Description

This invention relates to the configuration of a partition ceiling that is installed using a partition wall.

Suspended ceilings are often used in the ceiling structure of buildings. A suspended ceiling is constructed by suspending a ceiling frame consisting of rafters and rafters from a specific structure (such as a ceiling slab or H-shaped steel) above the building's ceiling via numerous suspension bolts, and attaching a ceiling panel (such as a decorative board) to the underside of the ceiling frame (see, for example, the configuration in Patent Document 1).

Therefore, with a suspended ceiling, there is usually a large space above the ceiling, which has the advantage of effectively securing the space needed to install electrical, water, air conditioning, etc.

JP 2020-7882 A

However, even if this is true in buildings such as gymnasiums and music halls where the ceiling depth is greater than a certain level, in places such as hospital corridors where the ceiling depth is shallow and there are partitions on both sides with a narrow gap between them, and where various types of equipment and numerous pipes are concentrated in the attic space, there is a problem that it is not possible to hang down multiple suspension bolts from the ceiling slab because the various types of equipment and numerous pipes interfere with each other.

The present invention was made to solve these problems, and aims to provide a partition ceiling that uses a pair of partition walls on the left and right, and has a specified connecting member that spans a specified upper position between the partition walls, taking into account the installation space for equipment and piping, and uses the connecting member to directly form the ceiling frame or to indirectly attach it via hanging bolts.

The partition ceiling of the present invention is configured with the following problem-solving means to solve the above problems.

(1) First Means of Solving the Problem of the Present Invention First, the partition ceiling in the first means of solving the problem of the present invention is a partition ceiling which utilizes a pair of left and right partition walls, spans a predetermined connecting member at a predetermined upper position taking into consideration the installation space for equipment and piping between the partition walls, and uses the connecting member to install a ceiling frame consisting of a joist support and a joist. The pair of left and right partition walls are made of a partition base consisting of a predetermined runner, a predetermined stud and a predetermined vibration stopper, and gypsum board which is integrally attached via a predetermined metal plate to a predetermined upper position on the opposing faces of the partition base, while the connecting member is made of a predetermined shaped steel, and both ends of the connecting member made of the predetermined shaped steel are connected and fixed to a predetermined metal plate of the partition wall via predetermined connecting and fixing fittings, and the ceiling frame is installed using the connecting member connected and fixed to the predetermined metal plate of the partition wall.

As a result, with the above configuration, a partition base consisting of a specified runner, a specified stud, and a specified anti-vibration stopper, and a pair of left and right partition walls consisting of gypsum boards that are integrally attached via a specified metal plate to a specified upper position on the opposing faces of the partition base, can be connected and integrated into a gate-shaped structure as a whole by connecting members.

Moreover, the connecting member itself is made of a specified shaped steel with high cross-sectional strength, and both ends of the connecting member made of the same specified shaped steel with high cross-sectional strength are firmly connected and fixed to the specified metal plates of the pair of left and right partition walls via specified connecting and fixing fittings. Therefore, the pair of left and right partition walls can be more firmly connected and integrated into a gate-shaped structure as a whole. Therefore, compared to the conventional configuration in which the ceiling frame is simply suspended from the ceiling slab portion via hanging bolts located between the pair of left and right partition walls, the strength and earthquake resistance of the pair of left and right partition walls that act as support walls supporting the ceiling frame are effectively improved.

As a result, in this configuration, the connecting members themselves that connect the pair of left and right partition walls are also reliably and firmly supported by the pair of left and right partition walls, and have a sufficiently high support strength as a cross beam material for directly or indirectly installing the ceiling frame. And, in this configuration, the ceiling frame is installed directly or indirectly using such connecting members with high support strength, so compared to the conventional configuration in which the ceiling frame is located between the pair of left and right partition walls and simply suspended from the ceiling slab portion via hanging bolts, the strength of the installed ceiling frame portion is effectively improved, and as a result, the rigidity and strength of the entire ceiling portion can be greatly improved.

In this configuration, unlike the conventional configuration in which the ceiling frame is suspended from the ceiling slab via multiple suspension bolts located between a pair of left and right partition walls, the connecting member is positioned at a specified upper position that takes into account the installation space for equipment and piping between the pair of left and right partition walls, and the ceiling frame is installed below this position.

Therefore, with this configuration, there is nothing in the space above the connecting member to the ceiling slab, making it possible to realize a completely free space. As a result, the installation of equipment and piping between the partition walls is also free, and the constraints that are based on the assumption that a ceiling frame must be installed are completely eliminated. This improves both workability and maintainability.

As described above, a partition wall generally consists of a pair of runners positioned above and below, multiple studs positioned between the runners and spaced apart at a specified distance, and multiple anti-sway bars arranged at a specified distance above and below to connect the multiple studs to each other. The runners are made of metal members with a U-shaped cross section, and are fixed with driving pins (or concrete nails) so that the upper one is fixed to the ceiling slab and the lower one is fixed to the floor slab with their open sides facing each other. Channel members (light channel steel) are generally used for the studs, and multiple through holes for inserting the anti-sway bars are provided at specified positions in the vertical direction, and the anti-sway bars are inserted in a cross state using the through holes and fixed to the studs using spacers. This connects the multiple studs to each other, achieving the anti-sway function.

Therefore, the pair of left and right partition bases that make up the main body of the partition wall are not structurally strong in themselves, and do not necessarily have sufficient strength or earthquake resistance as a building structure supporting the ceiling frame. In particular, they have a weakness in that they are prone to bending as a whole. For this reason, by connecting their vertical middle (middle) parts together at a specified interval in the longitudinal direction (front-to-back direction) with connecting members with high cross-sectional strength as described above and supporting them reliably at three points on the ceiling slab side, the middle part side, and the floor slab side, constructing a rigid gate-shaped structure with high bending strength as a whole is extremely effective in improving the earthquake resistance of the building structure.

(2) Second Means for Solving the Problem of the Present Invention Next, the partition ceiling in the second means for solving the problem of the present invention is characterized in that, in the configuration of the above-mentioned first means for solving the problem, a specified connecting and fixing bracket for connecting and fixing both ends of the connecting member to a specified metal plate of the partition wall is adopted which is configured to include a U-shaped cross-sectional receiving portion that fits in and receives both ends of the connecting member from above to below, and a pair of left and right mounting pieces that connect and fix the connecting and fixing bracket body including the receiving portion to the partition wall, and the pair of left and right mounting pieces are connected and fixed in advance to a specified metal plate that is attached to the partition base on the back side of the gypsum board using a specified screw-fitting means.

The partition ceiling of the second problem-solving means of the present invention employs a connecting fixture equipped with a U-shaped cross-sectional receiving portion that fits from above to below to receive both ends of a connecting member that connects a pair of left and right partition walls, and a pair of left and right mounting pieces that connect and fix the connecting fixture body including the receiving portion to each partition wall, and the connecting fixture is provided such that the pair of left and right mounting pieces are connected and fixed in advance to a specified metal plate attached to the partition base on the back side of the gypsum board using a specified screw-fitting means.

Therefore, with this configuration, when connecting a pair of left and right partition walls to each other with a connecting member, the connecting members can be connected simply by fitting both ends of the connecting member from above down into the U-shaped cross-sectional receiving portions of the connecting and fixing fittings on each partition wall, and the pair of left and right partition walls can be finally connected and fixed by simply screwing and fixing the U-shaped cross-sectional receiving portions with a specified screw fixing means, making the connecting and fixing work extremely easy.

Moreover, in this configuration, the pair of left and right mounting pieces of the connecting fixture are attached to a specified metal plate on the back side of the gypsum board that is already attached to the partition base using a specified screw-fastening means, so the mounting and fixing strength is high, and the connecting and fixing strength after connection is also high. The connecting strength is high in all directions of the connecting member, up and down, left and right, and axial direction. Therefore, earthquake resistance is also improved.

(3) Third problem-solving means of the present invention Next, the partition ceiling in the third problem-solving means of the present invention is characterized in that, in the configuration of the above-mentioned first or second problem-solving means, a specified connecting and fixing bracket is attached to a specified metal plate on the partition base side via a specified metal plate for attaching the connecting and fixing bracket between the gypsum board on the partition base side.

With this configuration, the strength of the mounting surface of the gypsum board, which does not have sufficient strength as a mounting surface for the connecting fasteners, is sufficiently reinforced by the specified metal plate for mounting the connecting fasteners, making it possible to mount the connecting fasteners more firmly in a more stable state. As a result, the connection strength between the connecting member and the partition base is also improved.

In particular, when the mounting structure uses a specified metal plate for mounting the connecting fasteners, the seismic resistance against horizontal seismic forces acting parallel to the wall surface of the partition base (the board surface of the gypsum board) is greatly improved compared to when the brackets are mounted directly to the board surface of the gypsum board, and the seismic resistance against horizontal seismic forces acting perpendicular to the wall surface of the partition base (the board surface of the gypsum board) is also greatly improved.

(4) Fourth problem-solving means of the present invention Next, the partition ceiling in the fourth problem-solving means of the present invention is characterized in that, in the configuration of the above-mentioned first or second problem-solving means, the connecting members that connect a pair of left and right partition walls to each other are configured as siding supports and siding supports of a ceiling frame consisting of siding, and the siding is directly attached to the underside to form a vertical ceiling.

With this type of configuration, no hanging bolts are required at all, and no vertical span is required to install the hanging bolts, so even in areas such as hospital corridors where the ceiling is shallow and there are partitions on both sides with narrow spaces between them, and where various types of equipment and numerous pipes are concentrated in the attic space, such as a hospital corridor, the ceiling frame can be installed with appropriate clearance without interfering with the various types of equipment and numerous pipes.

In addition, in this configuration, the connecting member and the ceiling frame are integrated, so that the pair of left and right partition walls are integrated into a portal shape via the ceiling frame. This further improves the strength of the entire building structure, including the ceiling frame and partition walls, making it more earthquake-resistant.

(5) Fifth solution to the problem of the present invention Next, the partition ceiling in the fifth solution to the problem of the present invention is characterized in that, in the configuration of the above-mentioned fourth solution to the problem, the rafters are made of square steel pipes, and openings of a specified diameter are provided on the underside of the rafters for screwing, and the upper surface of the rafters is attached to the underside of the connecting member by screwing through the openings.

This configuration increases the strength of the siding itself, and by screwing the siding to the underside of the high-strength connecting member that connects the pair of left and right partition walls and functions as a siding support, the siding can be easily and firmly attached.

As a result, orthogonal clips and the like are no longer necessary, making installation of the furring strips extremely easy. In addition, the furring strips themselves are made from high-strength square steel pipes, and are directly integrated with the underside of extremely strong connecting members that are connected to a pair of left and right partition walls, so their installation strength is sufficiently high.

(6) Sixth Solution to the Problem of the Present Invention Next, the partition ceiling in the sixth solution to the problem of the present invention is characterized in that, in the configuration of the first or second solution to the problem, multiple sheets of gypsum board are stacked together.

In this way, when multiple gypsum boards are stacked together, the thickness of the gypsum board portion that secures the connecting and fixing fittings to the specified metal plate on the partition base becomes thicker, making it easier and more stable to screw the connecting and fixing fittings to the specified metal plate on the partition base.

(7) Seventh problem-solving means of the present invention Next, the partition ceiling in the seventh problem-solving means of the present invention is characterized in that, in the configuration of the above-mentioned first or second problem-solving means, the connecting members that connect a pair of left and right partition walls to each other are configured as cross beam materials for hanging the ceiling frame, and the ceiling frame consisting of the siding support and the siding is configured to be hung from the connecting members via hanging bolts.

With this configuration, even in cases such as hospital corridors where the ceiling is particularly deep, it is possible to realize a suspended ceiling structure using (short) hanging bolts depending on the case while still ensuring sufficient strength for the portal structure using the connecting members.

(8) Eighth Solution to the Problem of the Present Invention Next, the partition ceiling in the eighth solution to the problem of the present invention is characterized in that, in the configuration of the above-mentioned first or second solution to the problem, the studs of the partition base that constitute the pair of left and right partition walls are square studs, and the connecting members that interconnect the pair of left and right partition walls are composed of square steel pipes.

In this configuration, the strength and rigidity of the partition base and connecting members are greatly improved, and the ceiling frame support strength of the ceiling frame support part consisting of a gate-shaped structure and the seismic strength of the building structure are both greatly improved.

(9) Ninth Solution to the Problem of the Present Invention Next, the partition ceiling in the ninth solution to the problem of the present invention is characterized in that, in the configuration of the above-mentioned first or second solution to the problem, the studs of the partition base that constitute the pair of left and right partition walls are lipped channel studs, and the connecting members that connect the pair of left and right partition walls to each other are composed of lip channel steel.

In this type of configuration, although they are inferior to square studs and square steel pipes, they both have a lip and have a cross-sectional strength close to that of square studs and square steel pipes, so the strength and rigidity of the partition base and connecting members are effectively improved, and the ceiling frame support strength of the ceiling frame support part consisting of the gate structure and the earthquake resistance strength of the building structure are effectively improved. In addition, compared to square studs and square steel pipes, they can be made relatively lighter and less expensive.

As a result, the present invention can effectively improve the strength, rigidity, and earthquake resistance of partition ceilings, including partition walls. Furthermore, not only in the case of a vertical ceiling structure that does not use hanging bolts, but also in the case of a suspended ceiling that uses hanging bolts, the shortest possible hanging bolts are sufficient, and the largest possible equipment space can be secured above the ceiling, which also allows for good coordination with the necessary equipment and piping.

Below, with reference to the attached Figures 1 to 56, we will explain in detail some specific forms for implementing the configuration of the partition ceiling of the present invention, which utilizes a pair of left and right partition walls and is installed between the pair of left and right partition walls via a connecting member.

<Configuration of the partition ceiling according to the first embodiment of the present invention: Figs. 1 to 12>
First, Figures 1 to 3 each show the configuration of the entire specified length portion of a partition ceiling in embodiment 1 of the present invention, which is installed using a pair of left and right partition walls, with Figure 1 being an oblique view of the entire specified length portion, Figure 2 being a front view of the entire specified length portion, and Figure 3 being a bottom view (underside view) of the entire specified length portion.

As mentioned above, the partition ceiling according to the first embodiment of the present invention is intended to be installed in a building that has a pair of partition walls on both the left and right sides, such as a hospital corridor, and is firmly attached by directly connecting and fixing both the left and right ends of the connecting members that make up the joist support to a specified upper position of the left and right partition walls.

In other words, in Figures 1 to 3, the reference numerals 1, 1 indicate a pair of partition walls installed on both the left and right sides of the corridor of the hospital, etc.

Each of the pair of left and right partition walls 1, 1 comprises a pair of runners 11, 11 located above and below, a plurality of studs (partition posts) 12, 12... located between the runners 11, 11 and erected at a predetermined interval from each other, a plurality of vibration braces 13, 13... arranged at a predetermined interval above and below and connecting the plurality of studs 12, 12..., and a partition base (reference numerals omitted) consisting of galvanized steel sheets (hot-dip galvanized steel sheets) 14, 14 of a predetermined vertical width (the length in the front-to-back direction is the same as that of the runners 11, 11) firmly screwed to the studs 12, 12... of the partition base. , 11, the length of the anti-sway bars 13, 13..., and the width between the studs 12, 12 at both front and rear ends), and gypsum boards (approximately 12.5 mm thick) 15, 15 attached to the opposing sides of the pair of left and right partition bases via the galvanized steel plates (approximately 0.8 mm thick) 14, 14 (the front-to-rear width corresponds to the length of the runners 11, 11, the length of the anti-sway bars 13, 13..., and the width between the studs 12, 12 at both front and rear ends, and the vertical height corresponds to the dimension between the upper and lower runners 11, 11 via the studs 12, 12, i.e., the height of the partition base).

The runners 11, 11 of the left and right partition bases are each made of a channel member (lightweight channel steel material) with a U-shaped cross section, and the upper one is fixed to the underside of the ceiling slab and the lower one is fixed to the upper surface of the floor slab with driving pins (or concrete nails) (not shown) with the open sides facing each other. In addition, in this embodiment, the studs 12, 12... are made of square studs (square steel pipes similar to the connecting member 31 described later can also be used) with a cross-sectional structure that is large in the left-right direction and small in the front-to-back direction, and each has multiple through holes (penetrating coaxially at the same position in the parallel installation direction) for inserting the vibration stoppers at predetermined positions in the vertical direction.

As shown in FIG. 4, the through hole for inserting the anti-sway bar has an anti-sway bar fixing groove 12a with clamping ribs (protrusions) 12b, 12b on the left and right at the bottom, a finger insertion hole 12c into which a finger can be inserted from the inside of the upper side, and a door structure with a bent anti-sway bar fixing piece (U-shaped cut plate) 17 between them. The anti-sway bar fixing piece 17 can be bent (opened and closed) in both directions, like a door, with its base (part without a cut groove) 17a as the center. For example, when the fixing piece main body part in the closed state as shown in FIG. 4 is bent by inserting a finger into the finger insertion hole 12c and bending it from the tip side to the front side by 90 degrees or more to the left, the entire area from the upper finger insertion hole 12c to the lower anti-sway bar fixing groove 12a is opened widely. In this open state, for example, a channel structure anti-sway bar 13, 13... is inserted with the non-web side (flange side) downward. Then, when the entirety is inserted, the sway stoppers 13, 13... are pushed downward and pushed into the sway stopper fixing groove 12a, and the flanges on both the left and right sides are clamped by the clamping ribs 12b, 12b on both the left and right sides. This reliably fixes the sway stoppers 13, 13... from moving left and right. After that, the fixing piece main body part of the sway stopper fixing piece 17, which was bent to the left, is returned to its original closed state as shown in Figure 4. As a result, the sway stoppers 13, 13..., which are pushed into the sway stopper fixing groove 12a and clamped by the left and right clamping ribs 12b, 12b and fixed left and right, are further reliably fixed up and down by the sway stopper fixing piece 17. Therefore, in this configuration, there is no need for an accessory (separate member) for fixing the sway stopper, as in the case of fixing using a spacer, and the work of fixing the sway stopper is significantly easier. In addition, the accessory for fixing the sway stopper will not come off due to the occurrence of an earthquake, and a secure fixed state can be maintained.

As a result, the multiple studs 12, 12... are interconnected by the anti-vibration devices 13, 13..., providing a reliable anti-vibration function.

In this way, a partition base is constructed of runners 11, 11, studs 12, 12..., and vibration braces 13, 13..., with a lattice structure (top and bottom two-point support structure) fixed to a ceiling slab (not shown) at the top and a floor slab (not shown) at the bottom. Galvanized steel plates (approximately 0.8 mm thick) 14, 14 of the above-mentioned specified top and bottom width are first screwed to the ceiling mounting parts on the opposing sides of this partition base, and then gypsum boards (approximately 12.5 mm thick) 15, 15 are attached to the galvanized steel plates 14, 14 as described above, and finally a pair of left and right partition walls 1, 1 as shown in Figures 1 to 7 are formed.

In this case, the galvanized steel sheets 14, 14 of the above-mentioned specified vertical width are screwed to the inner facing surfaces of the multiple studs 12, 12... that constitute the partition base. In this embodiment, the studs 12, 12... are square studs, so their cross-sectional strength is high and the mounting strength of the galvanized steel sheets 14, 14 is also high. In the same sense, the attachment strength of the gypsum boards 15, 15 is also high. In addition, each of the multiple studs 12, 12... is reliably connected and fixed in both the vertical and horizontal directions without loosening by the multiple vibration stoppers 13, 13... that have a high connecting and fixing strength as described above, so the flatness accuracy of the gypsum board mounting surface is high, and the entire gypsum boards 15, 15 are attached reliably and uniformly to the inner surface of the partition base without any steps. As a result, the connecting and fixing fittings 2, 2 via the gypsum boards 15, 15 described below to the galvanized steel sheets 14, 14 is also improved, and the fixing strength after connection is also improved.

Next, the pair of left and right partition walls 1, 1 thus formed are connected and fixed to the gate-shaped structure (H-shaped structure) by connecting members 31, 31, 31 for installing the ceiling frame at positions corresponding to the above-mentioned galvanized steel plates 14, 14. In this embodiment, the connecting members 31, 31, 31 for installing the ceiling frame (hereinafter simply referred to as connecting members) are made of square steel pipes in particular (in this example, as an example, a corner-caulked square steel pipe with a plate thickness of about 0.8 mm, which has particularly high cross-sectional strength, as shown in Figure 2 of JP Patent Publication No. 2020-7882, which was developed by the present applicant, is used).

On the other hand, at the connection positions (ceiling frame installation positions) on the partition walls 1,1 to which the left and right ends of the connecting members 31, 31, 31 correspond, connecting and fixing fittings (end fixing fittings) 2, 2, 2, 2, 2, 2 are attached to connect and fix the left and right ends 31a, 31a of the connecting members 31, 31 to the partition walls 1, 1, as shown in Figures 4 to 7, for example.

As shown in Figures 8 to 10, the connecting fixture 2 (one of the six shown in the figure is used as a representative) is cut out over a predetermined width (approximately 1/3 of the overall vertical dimension) from the front-to-rear middle to the rear end of a pair of parallel side plates 21a, 21a of a metal plate body 21 that has been bent horizontally in a U-shape as a whole, and the cut plate portion is extended uniformly to the left and right in a substantially flat state integrally with the rear end back plate 21b to form a pair of left and right mounting flanges (a pair of left and right ear-shaped mounting pieces) 21c, 21c. The mounting portions of the pair of left and right mounting flanges 21c, 21c on the partition walls 1, 1 are press-formed forward by a predetermined height, except for a predetermined width portion of the outer periphery, to form a ribbed surface structure with a reinforcing effect (step). In addition, at the lower end of the pair of left and right side plates 21a, 21a, a pair of end support pieces 21d, 21d of a connecting member 31 of a predetermined width bent horizontally inward is provided over the length from the front end side to the rear intermediate position (the rear side portion from the intermediate position is formed on the mounting surface of the sill 32: see the cross-sectional view of Figure 4). This forms a receiving portion with a U-shaped cross section into which both ends 31a, 31a of the connecting member 31 are inserted from above to below and received. In addition, reinforcing ribs 21f, 21f, 21f, 21f are provided at the upper and lower parts of the cutout openings 21e, 21e formed after cutting out the pair of left and right mounting flanges (cut plate portions) 21c, 21c of the pair of left and right side plates 21a, 21a over the length from the front end side to the rear end side of the opening.

Furthermore, four screw holes 21g, 21g, 21g, 21g are provided above and below the cutouts 21e, 21e of the pair of left and right side plates 21a, 21a, two screw holes 21h, 21h are provided above and below the rear end back plate 21b, and two screw holes 21i, 21i, 21i, 21i are provided at a predetermined distance from each other in the pair of left and right mounting flanges 21c, 21c. Of these two screw holes 21i, 21i, 21i, 21i on each side, only the outer screw holes are actually used.

In addition, V-shaped grooves 2a, 2b, 2c, 2d (two sets each for the top, bottom, left and right) are provided at the top and bottom middle parts of the back plate 21b of the connecting fastener 2 and at the middle parts of each end of the pair of left and right mounting flanges 21c, 21c, which serve as markers for mounting the connecting fastener 2 in the appropriate mounting position in line with the inking lines of the gypsum board 15, and these are used as references for accurate mounting to the front side of the gypsum board 15 (see the perspective view in Figure 7).

Then, the connecting fixture 2 thus constructed is firmly attached and integrated with the galvanized steel plates 14, 14 in the middle of the partition walls 1, 1 via the gypsum boards 15, 15 using the screw holes 21h, 21h in the rear end back plate 21b and the screw holes 21i, 21i, 21i, 21i in the pair of left and right mounting flanges 21c, 21c, as shown in Figures 4 to 7, for example.

Then, the ends 31a, 31a, 31a, 31a, 31a, 31a of the connecting members 31, 31, 31 for installing the ceiling frame are fitted and fixed to the connecting and fixing brackets 2, 2, 2, 2, 2, 2 on the left and right partition walls 1, 1. The ends 31a, 31a, 31a, 31a, 31a, 31a of the connecting members 31, 31, 31 to the connecting and fixing brackets 2, 2, 2, 2, 2, 2 are fixed to the connecting and fixing brackets 2, 2, 2, 2, 2 by using only two pairs of screw holes 21g, 21g in the diagonal direction out of the four pairs of screw holes 21g, 21g, 21g, 21g on each of the left and right side plates 21a, 21a, and screwing the screws 21n, 21n into those two pairs of screw holes 21g, 21g. In this case, a configuration is adopted in which the left and right side plates 21a, 21a are screwed together at different positions in the diagonal direction.

In the case of the partition ceiling structure of this embodiment, the connecting members 31, 31, 31 that connect the pair of left and right partition walls 1, 1 using the pair of left and right connecting fixing brackets 2, 2, 2, 2, 2, 2 as described above are themselves configured as sill supports that are part of the ceiling frame 3, and multiple sills 32, 32... are attached directly to the underside of the connecting members 31, 31, 31 in a state where they intersect at right angles, and a ceiling board (gypsum board) 4 made of a specified material is further attached to the underside of these sills 32, 32... to form the partition ceiling.

In this embodiment, the connecting members 31, 31, 31 that make up the sill supports of the ceiling frame 3 are rectangular steel pipes with particularly high cross-sectional strength as described above (corner crimped rectangular steel pipes with a plate thickness of approximately 0.8 mm), and are constructed with a cross-sectional structure that has a large vertical dimension and a small horizontal dimension, resulting in high load strength.

For the fixing, the ends 31a, 31a of the connecting member 31 made of the same rectangular steel pipe are inserted (fitted downward from above) between the pair of left and right side plates 21a, 21a of the connecting and fixing brackets 2, 2 that have been attached to the partition walls 1, 1 in advance as described above, for example as shown in Figures 4 and 5, and temporarily fixed. Then, the screws 21n, 21n, 21n, 21n are screwed through the diagonal screw holes 21g, 21g, 21g, 21g that are located at different positions in the pair of left and right side plates 21a, 21a, and finally fixed firmly. As a result, the connecting members 31, 31, 31 made of the rectangular steel pipes with high cross-sectional strength and load strength connect and integrate the vertical intermediate parts of the pair of left and right partition walls 1, 1 (the intermediate parts between the ceiling slab fixing parts and the floor slab fixing parts via the runners 11, 11) into a gate shape (H type). Therefore, the support strength of the pair of left and right partition walls 1, 1 is increased from the conventional two-point support state of only the ceiling slab fixing part and the floor slab fixing part via the upper and lower runners 11, 11 to a three-point support state including the support of the intermediate part. As a result, the rigidity and bending strength are greatly improved. Moreover, this connecting part is formed uniformly over the entire pair of left and right partition walls 1, 1 in a continuous manner at a predetermined interval in the front-to-rear direction (longitudinal direction) of the pair of left and right partition walls 1, 1 by multiple connecting members 31, 31, 31.... Therefore, the rigidity and strength of the entire pair of left and right partition walls 1, 1, which is not necessarily high in strength, consisting basically of the runners 11, 11, studs 12, 12..., vibration stoppers 13, 13..., and gypsum board 15, is effectively reinforced.

Next, the orthogonal clips 33, 33... shown in Figs. 11 and 12 are used to attach the soffits 32, 32... made of square steel pipes with high strength like the connecting member 31 to the lower side of the connecting member 31, which is the soffit support, in the cross direction. There are two types of orthogonal clips 33, 33...: a single type (single clip) in which the mounting portion 33b to the lower side soffit 32 is only on one side (left or right) as shown in Fig. 11, and a double type (double clip) in which the lower side mounting portion 33b is on both sides (left and right) straddling the connecting member 31, which is the soffit support, as shown in Fig. 12. In practice, one of these types is used depending on the case. In the illustrated example (for example, Figs. 1 and 2), for convenience, the two types of clips are used in combination, and the mounting state of each is shown for reference. However, in the actual mounting state (construction state), one type of clip is used according to the purpose.

The single clip in FIG. 11 and the double clip in FIG. 12 are both configured with an engagement portion 33a on the upper side of the hook-structured connecting member 31 and an inverted U-structured soffit attachment portion 33b on the lower side, and are configured with screw holes 33c, 33c and screw holes 33d, 33d on the contact surface with the connecting member 31 and the contact surface with the soffit 32, respectively. Then, as shown in FIG. 1 to FIG. 7, for example, the soffits 32, 32... are attached to the connecting member 31, which is the soffit support, by screwing the screws 33e, 33e, 33f, 33f through the screw holes 33c, 33c, 33d, 33d. In this case, the soffits 32, 32... are also made of high-strength square steel pipes, just like the connecting member 31. Therefore, the strength of the soffits 32, 32... is also high, just like the connecting member 31.

In this embodiment, the siding 32 is also attached to the underside of the connecting end 31a of the connecting member 31 connected and fixed to the connecting fixture 2. However, because the thick side plates 21a, 21a of the connecting fixture 2 are located on the left and right of this part, the common orthogonal clip 33 as shown in Figures 11 and 12 cannot be used (there are also reinforcing ribs 21f, 21f, and the dimensions do not match). Moreover, the siding 32 is a square steel pipe, and its entire cross section is closed.

Therefore, in this portion, as shown in Figures 4 and 5, for example, a large diameter hole (reference number omitted: see Figure 5) is drilled with a hole saw on the underside of the joist 32 made of the square steel pipe for screwing, and the upper surface side is screwed through the large diameter hole to the underside of the widthwise center of the connecting side end 31a of the connecting member 31 using a screw 21m.

As a result, according to the above configuration, the galvanized steel plates 14, 14, which extend in the front-to-rear direction, are screwed to the rectangular studs 12, 12, of the partition base, which consists of the channel-structured runners 11, 11, the high-strength rectangular studs 12, 12, and the channel-structured vibration braces 13, 13. The galvanized steel plates 14, 14, connect and fix the rectangular studs 12, 12, which are arranged in parallel at regular intervals in the front-to-rear direction, so that the upper and lower slab-side runners do not slide relative to each other. As a result, the earthquake resistance strength of the partition base in the wall direction can be greatly improved. Then, gypsum boards 15, 15, are attached to the partition base to form a pair of left and right partition walls 1, 1. This improves the earthquake resistance of the partition walls 1,1 in the wall surface direction, and in the event of an earthquake, the partition walls 1,1 will not swing in the wall surface direction and their front and rear ends will not collide with the fixed walls of the building, causing damage.

In the above configuration, multiple connecting members 31, 31... that form the ceiling frame 3 between the pair of left and right partition walls 1, 1 are arranged at a specified interval in the front-to-rear direction (wall surface direction), and each end 31a, 31a... is connected and fixed by screwing to the galvanized steel plates 14, 14... that are screwed to the square studs 12, 12... on the partition base side via the gypsum boards 15, 15... using connecting and fixing fittings (end fixing fittings) 2, 2... as shown in Figures 8 to 10.

As a result, the pair of left and right partition walls 1, 1 with improved strength in the wall surface direction are firmly connected and fixed to each other by the connecting members 31, 31... arranged in the wall surface direction, and are connected and integrated into a gate shape (H type) as a whole. Moreover, the connecting members 31, 31... use square steel pipes with particularly high cross-sectional strength, such as corner crimped steel pipes. Therefore, the connecting and fixing strength is sufficiently high. Therefore, the earthquake resistance strength of the pair of left and right partition walls 1, 1 in the direction perpendicular to each wall surface is also greatly improved. Therefore, the pair of left and right partition walls 1, 1 has sufficient strength as a building structure supporting the ceiling frame 3, and is optimal as a partition wall of this embodiment in which a ceiling is installed in a wall-supported state.

Furthermore, in the above configuration, the ceiling frame 3 consisting of the siding and the siding is constructed by using a number of connecting members 31, 31... that connect the pair of left and right partition walls 1, 1 to each other as siding supports, and attaching a number of sidings 32, 32... to the lower parts of the same number of connecting members 31, 31....

That is, in the case of the partition ceiling of this embodiment, the ceiling frame 3 is formed in such a manner that the multiple rafters 32, 32... are directly connected to the multiple high-strength connecting members 31, 31... that connect the pair of left and right partition walls 1, 1 to each other, and the multiple high-strength connecting members 31, 31... essentially form the rafter support of the ceiling frame 3. Therefore, in the case of this configuration, the ceiling frame 3 itself can be seen as being attached in a structure that directly connects it to the pair of left and right partition walls 1, 1. Moreover, not only the connecting members 31, 31... that form the rafter support of the ceiling frame 3, but also the rafters 32, 32... are made of high-strength square steel pipes. Therefore, the rigidity, strength, and earthquake resistance of the ceiling frame 3 itself are also high. Therefore, the partition ceiling of this embodiment, which is ultimately constructed in a gate type (H type) integrated with the pair of left and right partition walls 1, 1, has extremely high strength and excellent earthquake resistance.

Therefore, unlike the conventional structure in which a single ceiling frame consisting of a rafter and rafter is suspended from the ceiling slab via hanging bolts between a pair of left and right partition walls 1, 1, there is no swinging part at all, and the strength and earthquake resistance of the ceiling frame 3 and ceiling frame support part (support wall) are far higher.

In addition, in this configuration, unlike the conventional configuration in which the ceiling frame is suspended from the ceiling slab portion via multiple suspension bolts located between a pair of left and right partition walls, the multiple connecting members 31, 31... are connected in a bridging manner at a predetermined upper position that takes into account the installation space for equipment and piping between the pair of left and right partition walls 1, 1, and form the ceiling frame 3 at the same upper position.

Therefore, with this configuration, there is nothing in the space above the connecting members 31, 31, up to the ceiling slab, creating a completely free space. As a result, the installation of equipment and piping between the partition walls 1, 1 is completely free, and the restrictions that are based on the assumption that the ceiling frame 3 is installed are completely eliminated. This improves both the ease of installation and maintenance.

Furthermore, in the above-mentioned configuration, the connecting and fixing fittings (end fixing fittings) 2, 2... that connect and fix both ends of the connecting members 31, 31... to the galvanized steel sheets 14, 14... of the partition wall 1, 1 are configured to have a U-shaped cross-sectional receiving portion that fits in and receives both ends 31a, 31a of the connecting members 31, 31... from above and below, and a pair of left and right mounting flanges 21c, 21c that securely and firmly connect and fix the connecting and fixing fitting main body 21, 21 including the receiving portion to the partition wall 1, 1 side, and are securely and firmly connected and fixed to the galvanized steel sheets 14, 14 that are attached to the multiple square studs 12, 12... of the partition base on the back side of the gypsum boards 15, 15 via screwing means such as screws 21k, 21k.

Therefore, the work of connecting the multiple connecting members 31, 31... to the pair of left and right partition walls 1, 1 is extremely easy and has excellent workability.

As mentioned above, when square studs 12, 12... are used for the multiple studs of the partition base 1, 1, the strength of the studs themselves is higher than that of channel structure (groove structure), and the support parts of the vibration stoppers 13, 13... are four-point supported, so that once the fixed edge 17 of the door structure described above is closed, a strong fixed structure is realized, and the strength and earthquake resistance of the partition base 1, 1 itself is improved. Also, in the case of the fixed piece (spacer) 17 of the door structure described above, the fixed piece 17 itself is integrated with the studs 12, 12... at the base 17a, so there is no risk of it falling off due to earthquakes or other vibrations like a spacer with a separate member structure, and the above strength can be maintained permanently.

In this case, instead of the so-called square studs as described above, it is also possible to use high-strength square steel pipes (corner crimped steel pipes) similar to the connecting members 31, 31, for the multiple studs 12, 12.... By using such square steel pipes, the strength of the studs 12, 12... portion is further improved, and the strength and earthquake resistance of the partition base and partition wall 1, 1 portion are further improved.

Therefore, the technology can be used not only in the hospital corridors mentioned above, but also in high-ceilinged buildings such as warehouses, where there are partitions on the left and right.

In addition, in the above explanation, the multiple studs 12, 12... are described as being of a square type, but this can also be changed to a groove type.

<Structure of the partition ceiling according to Modification 1 of Embodiment 1: Figures 13 and 14>
In the above embodiment, as described above, the back plate 21b portion and the pair of left and right mounting flange portions 21c, 21c of the connecting fixing bracket 2 are screwed and fastened to the galvanized steel plates 14, 14 on the back side of the gypsum boards 15, 15 by using each of the screw holes 21h, 21h and either of the screw holes 21i, 21i with screws 21j, 21j and 21k.

In other words, in the case of this configuration, there is a galvanized steel plate 14, 14 on the back side of the fastening part, but there is no steel plate on the front side where the connecting and fixing bracket 2 abuts, and the board surface of the gypsum board 15, 15 is the direct mounting surface. Moreover, the mounting surface on the corresponding connecting and fixing bracket 2 side is a fastening surface with a small corresponding area only consisting of the back plate 21b part and the mounting flange part 21c, 21c part, and furthermore, this part is also press-molded for reinforcement, and the center part is bulged, so the width of the abutment surface on the outer periphery is narrower. Therefore, if the screws are fastened tighter than a certain level, there is a concern that the mounting surfaces will bite into the board surface of the gypsum board 15, 15 and a stable mounting state cannot be maintained.

In this modified example 1, taking such a case into consideration, for example, as shown in FIG. 13, a square galvanized steel plate (approximately 0.8 mm thick) 6 large enough to cover the entire back plate 21b and the pair of left and right mounting flanges 21c, 21c of the connecting fastener 2, as shown in FIG. 14, is attached in advance to the connecting fastener mounting surface of the gypsum boards 15, 15, and the connecting fastener 2 is attached via this galvanized steel plate 6. The galvanized steel plate 6 is the same as the galvanized steel plate 14 on the back side.

That is, as shown in FIG. 14, the galvanized steel sheet 6 has small-diameter screw holes 61, 61... for screwing and fixing the galvanized steel sheet 6 to the galvanized steel sheet 14 on the back side via the gypsum board 15 with the same screws (not shown) as described above, and large-diameter screw insertion holes (clear holes) 62, 62... for passing screws 21j, 21j and 21k for attaching the back plate 21b of the connecting fastener 2 and the pair of left and right mounting flanges 21c, 21c after screwing and fixing to the front surface of the gypsum board 15.

Therefore, when the connecting and fixing bracket 2 is attached to the front side of the gypsum board 15 via such a galvanized steel plate 6, even if the screws are tightened more than a certain level, the back plate 21b and the pair of left and right mounting flanges 21c, 21c of the connecting and fixing bracket 2 do not bite into the board surface of the gypsum board 15, and the connecting and fixing bracket 2 is firmly attached in a stable state. In other words, the galvanized steel plate 6 functions as a reinforcing plate that increases the strength of the board surface of the gypsum board 15 (the surface on which the connecting and fixing bracket 2 is attached).

As a result, the connection and fixing strength of the end 31a of the connecting member 31 and the connection strength of the left and right partition walls 1, 1 by the connecting member 31 are also improved. In particular, in the case of such an attachment structure via a galvanized steel plate 6, compared to a case where the connecting member 31 is attached directly to the board surface of the gypsum board 15, the earthquake resistance against horizontal earthquake forces acting parallel to the wall surface of the partition wall 1 (the board surface of the gypsum board 15) is greatly improved, and the earthquake resistance against horizontal earthquake forces acting perpendicular to the wall surface of the partition wall 1 (the board surface of the gypsum board 15) is also greatly improved. Therefore, it is possible to contribute to a stronger integration of the pair of left and right partition walls 1, 1 and the connecting member 31, and to an improvement in earthquake resistance.

When attaching the galvanized steel sheet 6 to the front of the gypsum board 15, V-shaped grooves 6a, 6b, 6c, and 6d are provided at the center of each of the top, bottom, left, and right sides of the galvanized steel sheet 6, which serve as markers for the top, bottom, left, and right attachment positions. The galvanized steel sheet 6 is then attached in the appropriate position by aligning these with the inked lines on the front side of the gypsum board 15.

On the other hand, as already mentioned, the upper and lower middle parts of the back plate 21b of the connecting fixing bracket 2 and the middle parts of each end of the pair of left and right mounting flange parts 21c, 21c are provided with similar V-shaped grooves 2a, 2b, 2c, 2d for mounting the connecting fixing bracket 2 in alignment with the marking lines of the gypsum board 15. Therefore, when a zinc-plated steel plate 6 is provided, the V-shaped grooves 2a, 2b, 2c, 2d are aligned with the V-shaped grooves 6a, 6b, 6c, 6d of the zinc-plated steel plate 6, so that the connecting fixing bracket 2 is similarly mounted in the appropriate position.

<Regarding the structure of the partition ceiling according to Modification 2 of Embodiment 1: illustration omitted>
The galvanized steel plate 6 is not only rectangular and individually provided to correspond to the connecting surfaces of each connecting fitting 2, 2... as in the above-mentioned variant example 1, but can also be changed to, for example, a horizontally elongated plate having the same shape and dimensions as the galvanized steel plate 14 on the back side of the above-mentioned gypsum board 15.

With this structure, the square studs 12, 12..., which were previously only secured by fitting the upper and lower runners 11, 11 together and engaging the vibration braces 13, 13..., are more firmly connected by the two galvanized steel plates 6 , 14 at the front and rear of the gypsum board 15, greatly improving the strength of the pair of left and right partition walls 1, 1 made up of the gypsum board 15 and the partition base in the longitudinal direction (wall surface direction), and also greatly improving the connecting strength (axial direction and perpendicular direction) of the multiple connecting members 31, 31... that connect them together, and the ceiling frame support strength (load-bearing strength). As a result, the earthquake resistance of each of these parts is also greatly improved.

<Configuration of the partition ceiling according to the second embodiment of the present invention: Figs. 15 to 22>
First, Figures 15 to 22 each show the overall configuration of a specified length portion of a partition ceiling according to embodiment 2 of the present invention, which is installed using a partition base. Figure 15 is a perspective view of the entire specified length portion, Figure 16 is a front view of the entire specified length portion, Figure 17 is a bottom view of the entire specified length portion, Figure 18 is an enlarged perspective view of the main parts as seen from the partition wall side (partition base side) showing the mutual configuration of a pair of left and right partition walls in the partition ceiling of embodiment 2, connecting members connecting those partition walls to each other, and ceiling frame parts configured with the connecting members as joist supports, and Figure 19 is an enlarged perspective view of the main parts as seen from the partition wall side (partition base side) showing the mutual configuration of a pair of left and right partition walls in the partition ceiling of embodiment 2, and connecting members connecting those partition walls to each other, and ceiling frame parts configured with the connecting members as joist supports. Figure 20 is an enlarged oblique view of the key parts viewed from the connecting member side (ceiling frame side) showing the mutual configuration of the frame parts; Figure 21 is an enlarged bottom view of the key parts on one end side of the connecting member showing the configuration of the connecting member that connects a pair of left and right partition walls in the partition ceiling and the ceiling frame part configured with the connecting member as a joist support; Figure 22 is an enlarged oblique view showing the configuration of a modified example in which the joist connecting fittings used to connect the connecting member that constitutes the joist support of the ceiling frame in the partition ceiling to the joist are changed from double clip type orthogonal clips to single type orthogonal clips.

The partition ceiling according to the second embodiment of the present invention is characterized in that the square studs 12, 12... in the partition base of the partition ceiling according to the first embodiment are replaced with channel members (channel steel with lips) 12, 12... with lips, and the overall shape of the through-holes 12a-12c of the sway stoppers 13, 13... is made into a mountain shape, and the upper part of the sway stoppers 13, 13... with a channel structure that is inserted and fitted with the flange side of the lower end 12a of the through-hole with a smaller opening diameter is fixed by a spacer 17 via a pressing piece 16.

In this second embodiment, as shown in Figures 15 to 20, for example, the double-clip type orthogonal clips 33, 33... described above are used to attach the furring strips 32, 32... to the connecting members 31, 31..., which serve as furring strip supports. However, these can all be changed to single-type orthogonal clips 33, 33..., as shown in Figure 22, for example.

All other configurations are the same as those of the partition ceiling in the first embodiment described above, and the same functions and effects can be achieved.

In this way, even if the square studs 12, 12... that make up the partition base are changed to channel members with lips, such as light channel steel with lips, a pair of left and right partition walls 1, 1 can be connected and integrated into a gate shape (H-shape) using connecting members 31, 31... made of multiple square steel pipes, just like in the case of the above-mentioned embodiment 1. Therefore, exactly the same action and effect as in the case of the above-mentioned embodiment 1 can be achieved.

<Configuration of the partition ceiling according to the third embodiment of the present invention: Figs. 23 to 26>
23 to 26 show the configuration of the main part of the partition ceiling according to the third embodiment of the present invention, which is installed using a partition base. FIG. 23 is an enlarged front view of the main part showing the configuration of a pair of left and right partition walls in the partition ceiling, a connecting member connecting the partition walls to each other, and a ceiling frame portion configured with the connecting member as a joist support. FIG. 24 is an enlarged front view of the main part showing the configuration of a pair of left and right partition walls in the partition ceiling, a connecting member connecting the partition walls to each other, and a ceiling frame portion configured with the connecting member as a joist support. Figure 25 is an enlarged oblique view of the key parts viewed from the partition wall side (partition base side) showing the mutual configuration of the ceiling frame parts constituted by a pair of left and right partition walls in the partition ceiling and connecting members that connect those partition walls to each other, and an enlarged oblique view of the key parts viewed from the connecting member side (ceiling frame side) showing the mutual configuration of the ceiling frame parts constituted by the connecting members as joist supports. Figure 26 is an enlarged oblique view showing the configuration of the mounting fittings (clips) that attach the joists to the connecting members, which are joist supports, in the partition ceiling.

The partition ceiling according to the third embodiment of the present invention is characterized in that the square studs 12, 12... in the partition base of the partition ceiling according to the first embodiment are changed to channel members 12, 12... with lip portions, the through holes 12a-12c of the sway braces 13, 13... are made generally mountain-shaped, the upper parts of the sway braces 13, 13... with the inserted channel structure are fixed by spacers 17, and the multiple connecting members 31, 31... connecting the pair of left and right partition walls 1, 1 are made of lip channel steel instead of the square steel pipes mentioned above. The rest of the configuration is the same as that of the partition ceiling according to the first embodiment, and the same actions and effects can be achieved.

In this way, even if the square studs 12, 12... that make up the partition base are changed to channel members with lip portions, such as light channel steel with lips, and the multiple connecting members 31, 31... that connect the pair of left and right partition walls 1, 1 to each other are changed to the square steel pipes described above and made of lip channel steel, the pair of left and right partition walls 1, 1 can be connected and integrated into a gate shape (H-shape) by the connecting members 31, 31... made of multiple lip channel steel, just as in the case of the above-mentioned embodiment 1, and its strength can be improved. Therefore, the same actions and effects as in the above-mentioned embodiment 1 can be achieved.

In this configuration, although the strength is inferior to square studs and square steel pipes, both have lips and have cross-sectional strength close to that of square studs and square steel pipes, so the strength and rigidity of the partition base and connecting members 31, 31... are effectively improved, and the ceiling frame support strength of the ceiling frame support part consisting of a gate structure (H-shaped structure) and the earthquake resistance strength of the building structure are effectively improved. Also, compared to square studs and square steel pipes, they have the relative advantage of being lighter and less expensive.

In this embodiment, the clip 34 that attaches the siding 32 to the connecting member 31, which is the siding support, has a connecting portion 34b with the lower siding 32 similar to that of the orthogonal clips 33, 33 in Figs. 11 and 12, as shown in Fig. 26, while the hook portion 34a on the upper end has a flat U-shaped cross section that properly engages with the lower lip portion of the lip channel steel. Each of these portions has screw holes 34c, 34d, 34d similar to those of the orthogonal clips 33, 33.

In addition, in this configuration, the side wall portion 21a on one side of the connecting fixture 2 is also connected using the upper and lower lip portions of the connecting member 31 made of lip channel steel (the other side uses the web portion). Therefore, it is possible to maintain a connecting strength almost the same as that of a square steel pipe (see the connected state in Figures 23 to 25).

In addition, in the above explanation, the multiple studs 12, 12... are described as grooved type with a lip portion, but it is also possible to change this to square type studs as in embodiment 1.

<Configuration of the partition ceiling according to the fourth embodiment of the present invention: Figs. 27 to 33>
Next, Figures 27 to 33 each show the configuration of a partition ceiling according to embodiment 4 of the present invention, which is installed by utilizing a partition base.

Figure 27 is a perspective view of the entire portion of the specified length of the partition ceiling, Figure 28 is a front view of the entire portion of the specified length of the partition ceiling, Figure 29 is an enlarged front view showing the structure of the connection part between the partition wall and the connecting member of the partition ceiling and the ceiling frame hanging part, Figure 30 is an enlarged perspective view showing the engagement structure of the upper end of the hanging bolt for hanging the ceiling frame with the connecting member of the partition ceiling, Figure 31 is an enlarged perspective view showing the structure of the engagement member (upper hook part) at the engagement part of the upper end of the hanging bolt for hanging the ceiling frame with the connecting member of the partition ceiling, Figure 32 is an enlarged perspective view showing the engagement structure of the lower end of the hanging bolt for hanging the ceiling frame with the rafter of the partition ceiling, and Figure 33 is an enlarged perspective view showing the attachment state of the rafter to the rafter receiver of the partition ceiling.

In the configuration of this embodiment 4, the same square steel pipes are used for the multiple connecting members 36, 36... that connect the pair of left and right partition walls 1, 1 to each other, as in the case of the above-mentioned embodiment 1, but in this embodiment, instead of directly connecting the rafters 32, 32... to the connecting members 36, 36..., the ceiling frame 3 consisting of the rafter supports 35, 35... and the rafters 32, 32... is suspended at a predetermined height using hanging bolts 38, 38... of a predetermined length to install it.

In this case, the above-mentioned connecting and fixing fittings 2, 2... are used to connect the pair of left and right partition walls 1,1 to the multiple connecting members 36, 36..., and they are connected and fixed in exactly the same way by bridging between the pair of left and right partition walls 1,1. The pair of left and right partition walls 1,1 also have exactly the same configuration. Therefore, the wall strength of the pair of left and right partition walls 1,1 themselves is improved, and they are connected and integrated with each other into a gate-shaped structure (H-shaped structure) by the multiple connecting members 36, 36..., improving the ceiling frame support strength and earthquake resistance in exactly the same way.

However, in this embodiment, the ceiling frame 3 is a normal ceiling frame, as shown in Figure 33, and is composed of sill supports 35, 35... and sills 32, 32..., both of which are made of channel-structured channel steel (C-shaped steel), and are connected together by orthogonal clips 41, 41..., 42, 42.... The sill supports 35, 35... of the ceiling frame 3 of the same configuration are suspended by a first hanger 37 on the upper side and a second hanger 39 on the lower side via suspension bolts 38, 38... of a specified length.

As shown in Figures 30 and 31, the upper first hanger 37 is configured to have a hook-shaped hook member body 37a that opens downward, a screw hole 37c for the connecting member 31 provided on the side wall of the hook-shaped hook member body 37a, a hanging bolt engagement piece 37b formed by bending the lower end side of the side wall horizontally, and a nut member 37d that screw-engages the upper end side of the hanging bolt 38 provided on the hanging bolt engagement piece 37b in a height-adjustable state. The side wall part of the hook member body 37a is screwed and fastened to the connecting member 31 by a predetermined screw 37e through the screw hole 37c, for example as shown in Figure 30. Then, the upper end threaded part of the hanging bolt 38 is screwed into the nut member 37d to hang the hanging bolt 38 to a predetermined length.

On the other hand, as shown in FIG. 32, the lower second hanger 39 is screwed to the lower end of the hanging bolt 38, and the sill support 35 of the ceiling frame 3 is engaged through the second hanger 39. As shown in the figure, the second hanger 39 is composed of a hook-shaped hook member body 39a that opens upward opposite to the first hanger 37, a hanging bolt engagement piece 39b formed by bending the upper end of the side wall of the hook member body 39a horizontally, and a nut member 39c that screw-engages the lower end of the hanging bolt 38 provided in the hanging bolt engagement piece 39b in a height-adjustable state. The hanging bolt engagement piece 39b is screwed to the lower end of the hanging bolt 38 with a screw-engagement portion by the nut member 39c.

Then, using the first and second hangers 37, 39 and the hanging bolts 38, the ceiling frame 3 (see Figure 33), consisting of the soffit supports 35, 35... and the soffits 32, 32..., is suspended to the desired height, as shown in Figure 29, for example.

In this configuration, even in the case of a hospital corridor, for example, where the ceiling is deeper than a certain level, it is possible to realize a suspended ceiling structure using hanging bolts (short) 38, 38... depending on the case, while ensuring sufficient strength of the gate-shaped structure (H-shaped structure) using the above-mentioned connecting members 31, 31.... And in the case of this embodiment, even if it is a suspended ceiling structure, the length of the hanging bolts 38, 38... is as short as possible, so there is little possibility of restricting the installation space for equipment, piping, etc. In addition, since the strength of the connecting members 31, 31... as a cross beam structure that connects the pair of left and right partition walls 1, 1 to each other is sufficiently high, the hanging strength and earthquake resistance of the ceiling frame 3 can be sufficiently ensured.

The sills 32, 32... that make up the ceiling frame 3 are available in a double type with a large web width and a single type with a narrow web width. Therefore, when actually installing the sills 32, 32..., as shown in Figure 29, either a double type clip 41 or a single type clip 42 is used for installation (Figure 33) according to the dimensions of the sills 32, 32....

<Configuration of the partition ceiling according to the fifth embodiment of the present invention: Figs. 34 to 36>
Next, Figures 34 to 36 each show the configuration of a partition ceiling according to embodiment 5 of the present invention, which is installed utilizing a partition base.

Figure 34 is an enlarged front view showing the structure of the connection between the partition wall and the connecting member of the partition ceiling and the ceiling frame hanging part, Figure 35 is an enlarged perspective view showing the engagement structure of the upper end of the hanging bolt for hanging the ceiling frame with the connecting member of the partition ceiling, and Figure 36 is an enlarged perspective view showing the engagement structure of the lower end of the hanging bolt for hanging the ceiling frame with the sill bracket on the ceiling frame side of the partition ceiling.

As shown in FIG. 34, the partition ceiling of this embodiment 5 is configured to suspend the ceiling frame 3 using multiple connecting members 36, 36... that interconnect a pair of left and right partition walls 1, 1, as in the above embodiment 4. However, the multiple connecting members 36, 36... that interconnect the pair of left and right partition walls 1, 1 and serve as cross beam members that suspend the ceiling frame 3 are not made of square steel pipes as in the above embodiment 4, but rather lip channel steel (channel steel with a lip) with a lip on the open end side of each flange, as shown in FIG. 35.

Correspondingly, the configuration of the first hanger 46 on the upper end side of the hanging bolt 38 has been changed to one suitable for engaging with the lip portion of the lip channel steel. That is, the first hanger 46 is composed of an inverted V-shaped hook piece 46a that engages with the lip portion of the connecting member 36 made of lip channel steel, and a horizontal engagement piece 46b equipped with a nut portion 46c that engages with the upper end of the hanging bolt 38 in a screwed state. On the other hand, the lower end side second hanger 47 that is located on the lower end side of the hanging bolt 38 and engages with the soffit support 35 of the ceiling frame 3 is composed of a U-shaped hook piece 47a that engages with the soffit support 35 of the ceiling frame 3 from below, and a horizontal engagement piece 47b equipped with a nut portion 47c that engages with the lower end of the hanging bolt 38 in a screwed state.

The configuration of other parts is basically the same as that of embodiment 4 above.

<Configuration of the partition ceiling according to the sixth embodiment of the present invention: Figs. 37 and 38>
Next, Figures 37 and 38 each show the configuration of a main part of a partition ceiling according to embodiment 6 of the present invention, which is installed using a partition base.

The partition ceiling of this embodiment 6 is characterized by a change in the structure of the first hanger on the upper end side of the hanging bolt 38 in the partition ceiling of the above embodiment 4, which uses connecting members 36, 36... made of square steel pipes. The configuration of other parts is the same as that of embodiment 4.

In this embodiment, the first hanger 50 on the upper end side of the hanging bolt 38 is made up of a fitting piece main body with a U-shaped cross section that is fitted from the side to the connecting member 36, a connecting support member 50c with a hat-shaped cross section and a bolt insertion groove that is interposed between the upper piece 50a side end and the lower piece 50b side end of the fitting piece main body, and nuts 50d, 50d for screwing into the upper end of the hanging bolt 38 that are integrally provided on the upper surface side of the end of the upper piece 50a and the lower surface side of the end of the lower piece 50b of the fitting piece main body, respectively.

The upper and lower ends of the flange portion of the hat-shaped cross-section connecting support member 50c along the side wall portion of the connecting member 36 are bent at right angles to both the upper and lower sides of the connecting member 36, so that they engage with both the upper and lower sides of the connecting member 36 in a U-shaped cross-section. As a result, the U-shaped cross-section fitting piece main body and the hat-shaped cross-section connecting support member 50c are set to face each other and enclose the connecting member 36 (with the suspension bolt insertion groove position of the connecting support member 50c and the screw hole positions of the nuts 50d, 50d of the upper piece 50a and lower piece 50b of the fitting piece main body aligned, respectively).

Then, in this set state, the connecting support member 50c is fixed to the side wall surface of the connecting member 36 with the screws 51, 51, and then, as shown in the figure, the upper end side of the hanging bolt 38 is inserted from below to above by a specified distance and screwed in, and is securely fixed with two sets of upper and lower nuts 50d, 50d.

With this configuration, the upper end of the hanging bolt 38 can be securely and firmly connected to the entire periphery of the connecting bolt 36 by the first hanger 50, allowing for a more stable hanging of the ceiling frame 3. As a result, earthquake resistance is also improved.

<Configuration of the partition ceiling according to the seventh embodiment of the present invention: Figs. 39 and 40>
Next, Figures 39 and 40 show the configurations of two types of orthogonal clips (single type and double type) in a partition ceiling according to embodiment 7 of the present invention, which is installed using a partition base similar to that of embodiment 1 above.

The orthogonal clip (single type) 33 in FIG. 39 and the orthogonal clip (double type) in FIG. 40 used in the partition ceiling of this embodiment 7 correspond to the orthogonal clip (single type) 33 in FIG. 11 and the orthogonal clip (double type) in FIG. 12 used in the partition ceiling of the above embodiment 1, respectively, but the orthogonal clip (single type) 33 in FIG. 39 and the orthogonal clip (double type) in FIG. 40 in this embodiment are characterized in that reinforcing bead parts 33g, 33g are provided on both the left and right sides in a mutually continuous state from the top surface part of the hook-structured engagement part 33a to the connecting member 31 made of a square steel pipe, through the side abutment surface, and over the entire top surface part of the mounting part 33b of the joist 32. The configuration of the other parts is the same as that of the above embodiment 1.

This configuration effectively improves the strength of the orthogonal clips (single and double types) 33, 33 that attach the siding 32 to the high-strength connecting member 31 connected to the pair of left and right partition walls 1, 1 via connecting fixtures (end fixing fixtures) 2, 2..., and further effectively improves the attachment strength of the siding 32 to the high-strength connecting member 31.

The beaded orthogonal clip (double type) 33 in this embodiment as shown in Figure 40 above can also be used in place of the beadless orthogonal clip (double type) 33 in embodiment 2 above.

<Configuration of a partition ceiling according to the eighth embodiment of the present invention: FIG. 41>
Next, FIG. 41 shows the configuration of an orthogonal clip (single type) in a partition ceiling according to embodiment 8 of the present invention, which is installed using a partition base similar to that of embodiment 2 above.

The orthogonal clip (single type) 33 in Fig. 41 in this embodiment is configured in place of the orthogonal clip 33 (single type) in Fig. 22 in the above-mentioned embodiment 2, and like the orthogonal clip (single type) 33 in Fig. 39 in the above-mentioned embodiment 7, is characterized in that reinforcing bead portions 33g, 33g are provided on both the left and right sides in a state where they are continuous with each other from the top surface portion of the engaging portion 33a of the hook structure that engages with the connecting member 31, through the side abutment surface, to the top surface portion of the mounting portion 33b of the siding 32. The configuration of other parts is the same as that of the above-mentioned embodiment 2.

This configuration effectively improves the strength of the orthogonal clips (single type) 33 that attach the siding 32 to the connecting member 31, and also effectively improves the attachment strength of the siding 32 to the connecting member 31, which is made of a high-strength square steel pipe.

<Configuration of the partition ceiling according to the ninth embodiment of the present invention: Figs. 42 to 48>
Next, Figures 42 to 48 show the configuration of a partition ceiling according to embodiment 9 of the present invention, which is installed using a partition base similar to that of embodiment 1 above.

First, Fig. 42 is a perspective view showing the overall configuration of the partition ceiling, which is installed in a wall-supporting structure using a pair of left and right partition walls, Fig. 43 is a front view showing the overall configuration of the partition ceiling, Fig. 44 is a bottom view showing the overall configuration of the partition ceiling, Fig. 45 is an enlarged front view of the main part of one end side (left end side) of a connecting member which connects the pair of left and right partition walls in the partition ceiling to each other and shows the configuration of the ceiling frame part configured with the connecting member as a joist support, Fig. 46 is a perspective view showing the pair of left and right partition walls in the partition ceiling and the partitions Fig. 47 is a perspective view from below of Fig. 46, showing the structure of the siding that connects a pair of partition walls to each other as a siding support, and Fig. 48 is a bottom view from below of Fig. 46, showing the structure of the siding that connects a pair of partition walls to each other as a siding support, and Fig. 48 is a bottom view from below of Fig. 46, showing the structure of the siding that connects a pair of partition walls to each other as a siding support, in the same partition ceiling.

As already mentioned, in the case of the configuration of the above-mentioned embodiment 1, the siding 32 is also attached to the underside of the connecting end 31a of the connecting member 31 connected and fixed to the connecting fixture 2, but because there are thick side plates 21a, 21a of the connecting fixture 2 on the left and right of this part, the orthogonal clips 33, 33 as shown in Figures 11, 12, 39 and 40 cannot be used (there are also reinforcing ribs 21f, 21f, and the dimensions do not match). Moreover, the siding 32 is a square steel pipe, and its entire cross section is closed.

Therefore, as shown in Figures 4 and 5, in this portion, a large diameter hole (reference number omitted: see Figure 5) for screwing is drilled with a hole saw on the underside of the joist 32 made of the square steel pipe, and the upper side is screwed through the large diameter hole to the underside of the widthwise center of the connecting end 31a of the connecting member 31 made of the square steel pipe using a screw 21m. In this case, a small diameter pilot hole is preferably drilled on the upper side.

This embodiment is characterized in that the same screw fastening configuration is applied not only to the furring strip 32 at the bottom of the connecting fixture 2 as described above, but also to all the furring strips 32, 32, ... that are attached between both ends of the connecting member 31. The configuration of the other parts is the same as in the first embodiment.

In other words, in the case of the sidings 32, 32... made of square steel pipes in this embodiment, as shown in Figures 47 and 48, large diameter holes 32b, 32b... for screwing are drilled with a hole saw on the underside, while small diameter pilot holes 32a, 32a... for screwing in are drilled on the upper side. Then, after the coaxial large diameter holes 32b, 32b... and small diameter pilot holes 32a, 32a... of the sidings 32, 32... are aligned with the center of the underside of the connecting member 31, they are fastened and fixed by screwing in the screws 21m, 21m... from the lower side.

As a result, a neat partition ceiling base is realized that does not have any of the orthogonal clips 33, 33, etc. as described above, as shown in Figures 42 to 46.

With this configuration, there is no need for multiple orthogonal clips 33, 33..., which significantly reduces parts costs. In addition, installation work is greatly simplified. The structure of the ceiling frame part is simplified, making it possible to reduce weight, and many other benefits.

As mentioned above, the strength of the connecting member 31 made of square steel pipes is very high, and the girders 32, 32... themselves are also made of square steel pipes and are very strong, so by using screws 21m, 21m... that have sufficient strength, sufficient strength can be achieved for the ceiling board 4. In particular, with this configuration, the strength of the mounting part is the same in all 360-degree directions, and there are no weak points, which is an advantage.

In addition to the above configuration, it is also possible to further improve the attachment strength by optionally providing the above-mentioned orthogonal clips (single type and double type) 33, 33... at a predetermined portion, for example at a position spaced apart by a predetermined distance.

<Configuration of a partition ceiling according to the tenth embodiment of the present invention: Figs. 49 to 50>
Next, Figures 49 and 50 show the configuration of a partition ceiling according to embodiment 10 of the present invention, which is installed using a partition base similar to that of embodiment 2 above (channel steel with lips for the studs 12 and square steel pipes for the connecting members 31).

The partition ceiling of this configuration is characterized by the fact that the connecting member 31 is made of a square steel pipe and the attachment structure of the joists 32, 32... made of square steel pipes is exactly the same as in the ninth embodiment. All other configurations are the same as in the second embodiment.

Even with this configuration, the same effect as in embodiment 9 above can be achieved.

<Configuration of a partition ceiling according to embodiment 11 of the present invention: Figs. 51 to 52>
Next, Figures 51 and 52 show the configuration of a partition ceiling according to embodiment 11 of the present invention, which is installed using a partition base similar to that of embodiment 3 above (channel members with lip portions on the studs 12, and lip channel steel for the connecting members 31).

The partition ceiling of this configuration is characterized by the fact that it employs an attachment structure for the connecting members 31 made of lip channel steel, and the joists 32, 32... made of square steel pipes, exactly the same as in the ninth embodiment above. All other configurations are the same as in the third embodiment above.

Even with this configuration, the same effect as in embodiment 9 above can be achieved.

<Configuration of a partition ceiling according to embodiment 12 of the present invention: Figs. 53 to 54>
Next, Figures 53 and 54 show the configuration of a partition ceiling according to embodiment 12 of the present invention, which is installed using a partition base similar to that of embodiment 1 above (square steel pipes for studs 12 and square steel pipes for connecting members 31).

In the configuration of this embodiment, as shown in Figures 53 to 54, for example, instead of the single gypsum board 15 in the above-mentioned embodiment 1, two gypsum boards, a first and a second gypsum board 15a, 15b are used, and the same mounting structure for the rafters 32, 32... as in the above-mentioned embodiment 9 is adopted.

In this embodiment, the galvanized steel plate 14 is screwed directly to the studs 12, 12, and two sheets of gypsum boards, the first and second sheets of gypsum boards 15a, 15b, are provided behind the galvanized steel plate 14. The connecting fittings (end fixing fittings) 2 are screwed to the galvanized steel plate 14 via the first and second sheets of gypsum boards 15a, 15b. In the figure, 21p is a screw that fixes the galvanized steel plate 14 to the studs 12, and 21k is a screw that fixes the connecting fittings (end fixing fittings) 2 to the galvanized steel plate 14.

In this way, by adopting a configuration in which the first and second gypsum boards 15a, 15b are stacked together as the gypsum board section, the thickness of the gypsum board section that fixes the connecting and fixing fittings (end fixing fittings) 2 to the galvanized steel plate 14 becomes thicker (12.5 mm x 2 = 25 mm), making it easier and more stable to screw the connecting and fixing fittings (end fixing fittings) 2 to the galvanized steel plate 14 on the stud 12 side.

On the other hand, if the plasterboard portion is constructed by stacking multiple sheets of plasterboard in this way, the thickness of the plasterboard portion will increase, and the installation problems with the connecting fixture 2 described in the section of Variation 1 of the first embodiment above will also increase.

Therefore, when adopting a configuration in which multiple sheets of gypsum boards are stacked as described above, the connecting and fixing brackets 2 can be attached using galvanized steel sheets 6 for attaching the connecting and fixing brackets 2, as in Variation 1 of the above-mentioned embodiment 1, as necessary. In this way, when multiple sheets of gypsum boards are stacked to achieve ease and stability in the installation work, it is also possible to simultaneously achieve stable installation strength and durability of the attached connecting and fixing brackets 2.

This configuration of the gypsum board portion being made up of multiple sheets of gypsum board can also be used in exactly the same way when the connecting member 31 portion is a square steel pipe and the studs 12, 12 portion are a channel member with a lip portion, or when the connecting member 31 portion is a lip channel steel and the studs 12, 12 portion are a channel member with a lip portion.

<Configuration of a partition ceiling according to embodiment 13 of the present invention: Figs. 55 to 56>
Next, Figures 55 to 56 show the configuration of a partition ceiling for embodiment 13 of the present invention, which is installed using a partition base similar to that of embodiment 1 above (square steel pipes for studs 12 and square steel pipes for connecting members 31).

In the configuration of this embodiment, as shown in Figures 55-56, for example, instead of the single gypsum board 15 in the above-mentioned embodiment 1, two gypsum boards, a first and a second gypsum board 15a, 15b are used, and the same mounting structure for the rafters 32, 32... as in the above-mentioned embodiment 9 is adopted.

In this embodiment, the galvanized steel plate 14 is screwed to the studs 12, 12 via a first plaster board 15a, and two second plaster boards 15b are provided behind it, and a connecting metal fitting (end fixing metal fitting) 2 is screwed to the galvanized steel plate 14 via the second plaster board 15b. In the figure, 21p is a screw that fixes the galvanized steel plate 14 to the stud 12, and 21k is a screw that fixes the connecting metal fitting (end fixing metal fitting) 2 to the galvanized steel plate 14.

When this configuration of stacking the first and second gypsum boards 15a, 15b is adopted, as in the case of the above-mentioned embodiment 12, the thickness of the gypsum board portion that fixes the connecting fasteners (end fasteners) 2 to the galvanized steel plate 14 becomes thicker (12.5 mm x 2 = 25 mm), making it easier and more stable to screw the connecting fasteners (end fasteners) 2 to the galvanized steel plate 14.

Moreover, in this embodiment, unlike the configuration of embodiment 12 above, the galvanized steel plate 14 that serves as the mounting base for the connecting fastener (end fastener) 2 is positioned midway between the first and second gypsum boards 15a, 15b. Therefore, even though the overall thickness of the gypsum board section does not change, the galvanized steel plate 14 that serves as the direct mounting base corresponds to the connecting fastener (end fastener) 2 via only the second gypsum board 15b (one sheet).

Therefore, while maintaining the ease of screw fastening and stability similar to those of the above-mentioned embodiment 12, it is possible to achieve a relatively high connection strength compared to the above-mentioned embodiment 12. As a result, with this configuration, it is also easy to attach handrails, etc. to the partition walls 1, 1.

When the plasterboard portion is constructed in this way from multiple sheets of plasterboard with galvanized steel sheets 14 sandwiched between them, there is only one sheet of plasterboard between the galvanized steel sheets 14 and the connecting fixture 2, but problems still arise with the installation of the connecting fixture 2, just as in the case described in the variant 1 of the first embodiment above.

Therefore, even when this configuration is adopted, the connecting and fixing brackets 2 can be attached using the same galvanized steel plate 6 for attaching the connecting and fixing brackets 2 as in Variation 1 of the above-mentioned embodiment 1, if necessary. In this way, when two sheets of gypsum board are stacked as a whole, and ease and stability of the installation work are realized, stable installation strength and durability of the attached connecting and fixing brackets 2 can be realized at the same time.

In this case, there is only one piece of gypsum board between the stud 12 and the galvanized steel plate 14, and one piece of gypsum board between the galvanized steel plate 14 on the stud 12 side and the galvanized steel plate 6 on the connecting fixture 2 side. Therefore, even though there is gypsum board between them, the connection strength between the stud 12 and the galvanized steel plate 14, and between the galvanized steel plate 14 and the galvanized steel plate 6 (connecting fixture 2) is maintained at a sufficiently high level.

This configuration in which the gypsum board portion is made up of multiple sheets of gypsum board with galvanized steel sheet 14 interposed between them can also be used in exactly the same way when the connecting member 31 portion is a square steel pipe and the studs 12, 12 portion are a channel member with a lip portion, or when the connecting member 31 portion is a lip channel steel and the studs 12, 12 portion are a channel member with a lip portion.
