Description

  The present invention relates to a suspension system for maintaining a glass plate or other plate-like object in a suspended state. The invention further relates to such a suspension system with improved seismic isolation performance.

Buildings with a certain floor area or more are obliged to install smoke barriers in order to save time evacuating from smoke generated during a fire. The smoke-proof hanging wall is configured by connecting a number of plates (such as glass plates) that are lowered from the ceiling to a predetermined height. The plates are not only arranged in a straight line, but also arranged in different directions, depending on the shape and area of the room. Moreover, the height of the lower edge of the plate is adjusted to be a certain height determined from the structure of the room to be constructed so as to be suitable for the height of the smoke exhaust window.
Conventionally, as shown in FIG. 1, the smoke-proof hanging wall is attached by inserting plates 4 and 5 into a longitudinal opening on the lower side of the frame 1 attached to the ceiling, and hanging metal fittings 2 lowered from the frame 1. This was done by placing both corners of the plate on the receiving part 3 of the plate.
However, depending on the circumstances of the individual room to be constructed, such as the height of the smoke exhaust window and the ceiling height, the vertical width of the plate required for the smoke-proof hanging wall differs, so the hanging bracket of the appropriate length 2 had to be prepared for each room in advance. Moreover, the ceiling of the room is not necessarily at the same height from the floor over the entire surface, and may have steps, and even in such a case, the lower edge of the smoke-proof hanging wall is at the same height from the floor. Since it is necessary to align, it was necessary to further prepare what adjusted the length of the hanging metal fitting 2 according to the level | step difference of a ceiling surface. In such a case, adjustment of the length of the hanging metal fitting 2 has been performed by cutting the middle of the shaft of the hanging metal fitting 2 supplied at a standard length, and partially overlapping and welding. In addition, at the refraction point where the plate row changes direction, the suspension bracket 2 that supports the corner portion where the two plates meet must be bent at an angle that matches the angle formed by the plates on the left and right sides. In addition, it is necessary to prepare the hanging metal fitting 2 having such a shape in advance.
Under these circumstances, conventionally, when constructing a smoke-proof hanging wall, it is necessary to prepare in advance all the necessary number of each length and shape of the suspension fittings 2 for each target room. For this reason, before a large-scale construction in a newly built building or the like, a very complicated and time-consuming and costly preparation work is required.
In addition, in the conventional smoke-proof hanging wall, the plate is usually mounted at a position away from the hanging bracket by vertically inserting the plate into the frame 1 and then shifting the plate in the horizontal direction so that the front corner is suspended by the hanging bracket 2. The rear corner portion is then supported by sliding the front half portion of the receiving portion 3 of the next hanging bracket 2 under the rear corner portion. 3 is carried out in an iterative process in which the front corner of the next plate is placed on the latter half of 3. Alternatively, depending on the mounting location, the plate is slightly inclined between a pair of suspension brackets 2 already provided at a fixed position and inserted into the frame 1 while avoiding a collision with the receiving portion 3, and then vertically. Returning and placing on the receiving part 3 is also performed.
In any stage of these attachment processes, the last plate is placed only on the first half of the receiving portion 3 of the hanging metal fitting 2, and thus is in a mechanically unstable state. For this reason, there is always a danger that the receiving part 3 tilts due to the load of the plate and falls backward to cause the plate to fall. Then, when the last piece falls off, the hanging bracket 2 on the rear side of the plate immediately preceding it becomes the same state and immediately exposed to the same instability, and the last plate falls. In response to the recoil of the plate, there is a risk that the plate will fall one after another. Therefore, in order to prevent such dropping and ensure safety, the plate mounting operation requires careful attention during construction.
In addition, in the conventional smoke-proof hanging wall using the hanging fitting 2, there is a gap between the two plates so that the shaft portion of the fishing fitting 2 is sandwiched between them, and it is necessary to close this to prevent smoke from flowing out. In addition, since it is necessary to blindly hide the shaft portion of the hanging metal fitting, a silicone sealant or the like that closes the gap is required, and the joint width is considerably wide and there is a problem in appearance in terms of color. Further, when an available standard-length suspension fitting is used as it is, the vertical width of the plate is defined by this, so that the dimension adjustment according to the aesthetics cannot be performed.

The present invention is a system for mounting an arbitrary number of plates in a form suspended from above like a smoke-proof hanging wall under the above background, and can simplify the preparation for mounting the plates, It is an object of the present invention to provide a plate suspension system that improves ease of handling and safety during installation work.
Another object of the present invention is to provide such a play and suspending system having an improved seismic isolation function in the event of an earthquake.
Instead of supporting the plate from below with the hanging metal fitting 2 (the receiving portion 3) as in the prior art, the present inventor has studied for a system that can easily support the upper edge of the plate to be attached. Completed the invention. That is, the present invention

These connecting members are planes such as adjacent vertical edges of a plurality of plates suspended by the plate suspension system of the present invention, or the vertical edges of the plates and the wall surfaces of the building or the side surfaces of other plates. It is easy to ensure an appropriate distance between the two (the former is, for example, 4 ± 2 mm, the latter is, for example, 10 mm), and prevents them from directly striking, and can be provided in the connecting member and When the building shakes during an earthquake, the plate suspension system is seismically isolated by giving flexibility to the connecting portion to prevent or weaken the stress in the plate due to the shaking. Is granted.
Further, these connecting members have one or more flexible protrusions or protrusions on the inner side of the receiving portion, which can be brought into contact with the end surface of the longitudinal edge of the plate. Good. Such a flexible protrusion or ridge absorbs the pressing force between the edge of the plate accommodated in the receiving portion and the connecting member in the event of an earthquake, further improving the seismic isolation performance of the plate suspension system. Increase.
The protrusions or ridges of the connecting member span the entire length, which can accommodate suspension bolts used in plate suspension systems such as conventional types of smoke-proof hanging walls in the interior or together with the bottom surface of the receiving part. A space extending in the longitudinal direction may be defined. Such a connecting member can be used in combination with the plate suspension system of the present invention and, in some cases, with a type of system in which a plate is attached using suspension bolts.
The connecting member is snapped from both sides of the plate at the center of the bottom of the receiving portion by a set of longitudinally extending fitting means defining a longitudinally extending space in which a suspension bolt can be accommodated. It may be composed of two parts to be joined. In such a connecting member, the snap-type fitting means may constitute a protrusion or a ridge extending in the longitudinal direction.
The present invention also provides a frame member, a holding member, a locking member, and a connecting member that constitute the plate suspension system.
Furthermore, the present invention is not limited to the plate suspension system of the present invention or a plate suspension system such as a conventional type of smoke-proof hanging wall. There is also provided a flexible connecting member for a plate suspension system, which is provided with an elongate receiving part for front and rear receiving each of the edges of the plate.

A method is also provided.
In the present invention, for example, when installing a smoke-proof hanging wall as an example, the frame member, the holding member, and the locking member are common as long as a plate having a vertical width determined according to the situation of the room is prepared. Therefore, preparation before construction is greatly simplified. In addition, the workability at the time of attachment is remarkably improved, the labor cost can be reduced, and the structure of the locking member is much simpler than the conventional hanging bracket, so that the material cost is also reduced. Furthermore, since each plate can be suspended stably, the danger of dropping in the middle of attachment is eliminated, and the safety at the time of work increases. Still further, since conventional suspension brackets are not used, not only the degree of freedom in setting the dimensions of the plate is increased, but also the plates can be directly abutted and arranged without gaps, so that the appearance is more beautiful. The whole design can be considered.
The plate suspension system of the present invention is not only for the installation of smoke-proof hanging walls, but also as a sash for indoor suspension partition walls, suspension interior and exterior walls of buildings, and window glass attachment. Can also be used. In particular, those using the above-described connecting member between plates or between a plate and a wall surface are excellent in seismic isolation performance.

In the present invention, the “frame member” may be long corresponding to suspending a desired number of plates, or may be used by abutting the ends of short ones, so that the length thereof is particularly limited. There is no. The other dimensions of the “frame member” are not particularly limited, but may be the same as those of a normal frame that is conventionally used together with a hanging bracket.
The longitudinally extending “pockets” provided on both sides of the opening of the frame member may extend uniformly from one end to the other end of the frame member and be open at both ends.
The length of the holding member is not particularly limited as long as it is within the length of the upper edge of the plate to be attached. Usually, it is sufficient to fix the plate around both corners, so a length of about several centimeters is sufficient.
Since the “groove” provided in the holding member is for inserting and fixing the upper edge of the plate there, it is necessary to have a groove width conforming to the thickness standard of the plate to be inserted. is there. The upper edge of the plate in the groove can be fixed using an adhesive. An appropriate adhesive may be appropriately selected from commercially available materials known to those skilled in the art in consideration of the surface material of the suspended plate and the material of the holding member. Both the frame member and the holding member are preferably formed (for example, extrusion molding) from aluminum, but are not limited thereto.
The locking member is, for example, one having a bent or bent end view shape or a shape including such a shape (for example, a shape having a straight portion and a portion protruding sideways in the middle). It may be. For convenience, for example, a substantially rectangular plate is refracted or curved along the longitudinal direction, but it is not necessarily a uniform plate. For example, a bent or bent ring having the same outline as such a plate, a plate with a center or other unnecessary portion cut out in terms of strength, or an end view shape similar to such a plate (ie, a frame member) Any other shape that gives a shape when one side is inserted into the pocket and viewed from the longitudinal direction of the frame member may be used. For example, when an aluminum plate is used as the locking member, it can be pressed and bent or curved along the longitudinal direction. Moreover, you may form the same shape with a leaf | plate spring material.
The plate suspension system of the present invention can be used very advantageously for the installation of smoke-proof hanging walls as described above, as well as suspension partition walls for partitioning rooms, It can be used for a wide range of applications such as sashes for outer walls, inner walls or window glass, and other plate-like objects. The material of the plate to be suspended may be glass, metal, stone, ceramic, synthetic resin, wood, plywood or other appropriate materials.

Hereinafter, the present invention will be described more specifically with reference to typical examples. However, the present invention is not intended to be limited to the examples.
FIG. 1 shows an example of a conventional smoke proof wall system. Reference numeral 1 denotes a frame (part of) that is attached to the ceiling so as to be suspended from a field receiver (C bar) in the ceiling, and the upper end of the hanging metal fitting 2 is hung on the lower side. The suspension fitting 2 has a receiving part 3 which is folded on both sides at the lower end, and a corner part of the plate is placed on and supported by this. Reference numeral 4 denotes a plate (glass) to be attached, and reference numeral 5 denotes a plate attached first.
FIG. 2 is a perspective view showing an example of the plate suspension system of the present invention. In the figure, reference numeral 11 denotes a frame member. In the figure, only a part of the length is cut out. Reference numeral 12 denotes a suspended plate made of, for example, glass. For convenience of explanation, the plate 12 is also shown in a reduced overall length. The upper edge of the plate 12 is inserted below the frame member 11, and holding members 13a and 13b are fixed to the upper edge at two locations. This fixing is performed by fixing both surfaces of the portion of the plate 12 inserted into the groove and both surfaces of the grooves of the holding members 13a and 13b facing each other with an adhesive. The holding members 13a and 13b thus integrated with the plate 12 are supported from below in the frame member 11 by a pair of locking members 14a and 14b, respectively. Each of the locking members 14a and 14b is inserted into each of the two rows 18 of pockets 18 in the longitudinal direction, the lower portion of which is provided below the frame member 11.
FIG. 3 shows the frame member 11 and the locking members 14a and 14b immediately before the plate 12 to which the holding members 13a and 13b are fixed is attached. As can be seen in the figure, the locking members 14a, 14b are both located in the pair of pockets 18 that extend in the longitudinal direction of the frame member 11 on both sides of the opening 16 that extends in the longitudinal direction. Is inserted. In order to insert the locking members 14 a and 14 b into the pocket 18, it is only necessary to manually insert the locking members 14 a and 14 b into the frame member 11 from below the opening 16 and insert the lower portion into the pocket 18. Since the upper portions of the locking members 14a and 14b thus inserted protrude into the opening 16, the inside of the pocket 18 can be slid to any position by touching the opening 16 with the tip of the driver or fingers.
As can be seen in FIG. 4, which is a cross-sectional view of the system of the present invention with the plate attached, the opening 16 of the frame member 11 is somewhat wider than the width of the holding members 13a, 13b. Therefore, the upper edge portion of the plate 12 to which the holding members 13a and 13b are fixed can be inserted into the frame member as it is from below the frame member 11 through the opening 16. When the plate 12 is inserted, the locking members 14a and 14b are placed in the pockets 18 at appropriate positions so that the locking members 14a and 14b protruding into the opening 16 do not hinder the passage of the holding members 13a and 13b. It is slid to an appropriate position between the holding members 13a and 13b. After the holding members 13a and 13b on the plate 12 are inserted into the frame member 11, the locking members 14a and 14b are lifted from the gap between the opening 16 and the plate 12 with the tip of the driver or other appropriate tool while being lifted. The suspension of the plate 12 is completed by pushing and sliding it directly below the holding members 13a, 13b and placing the holding members 13a, 13b on the locking members 14a, 14b at that position.
3 and 4, reference numeral 20 denotes a protrusion extending from the inner surface on both sides of the frame member 11, and the distance between the tips thereof is slightly larger than the width of the holding members 13 a and 13 b (about 1 mm on both sides). It is. For this reason, the holding members 13a and 13b inserted into the frame member 11 are restricted from shifting laterally. In this embodiment, the protrusion is a round bar-like protrusion extending in the longitudinal direction. However, as long as the holding members 13a and 13b are shifted to the side and abut against this to prevent the deviation, The shape is arbitrary. For example, you may comprise a protrusion part by narrowing the dimension of a horizontal direction by making the upper half inside the frame member 11 thick.
FIG. 5 shows a cross-sectional view of only the frame member 1. In this embodiment, the frame member 11 has a width of about 27 mm and a height of about 35 mm, and the distance between the tips of the pair of protrusions 20 is about 15 mm. The two rows of pockets 18 extending in the longitudinal direction each have a depth of about 7 mm and a gap width of about 2.5 mm. 22 is an engaging means used when suspending the frame member 11 itself, and this is a cut-out defined between the ends of a pair of oppositely protruding longitudinally extending L-shaped ridges 24. It is made up of. The lateral width of the ridge 24 is about 7.5 mm, the gap between the cutouts 22 is about 12 mm, and the gap between the L-shaped ridge 24 and the top plate 25 is about 2.5 mm. These protrusions 24 can be engaged with each other by inserting an engagement protrusion plate fixed in a T-shape at the tip of a conventional frame suspension bolt and rotating it 90 ° between them.
FIG. 6 shows the holding member 13 (all common). The holding member 13 has a groove 30 for inserting the plate 12 on the lower side. The inner surface of the groove 30 is provided with a plurality of longitudinal protrusions 31 (or recesses between them), and these protrusions 31 (or recesses) are formed by applying an adhesive into the groove. When the plate 12 is bonded, the fixation between the plate 12 and the holding member 13 is strengthened by acting to increase the adhesive force between the cured adhesive and the groove surface. The lower surface 32 of the holding member 13 has an inclination (in the present embodiment, about 20 °) that falls toward the groove on both sides of the groove. This inclination contributes to stabilizing the engagement between the upper part of the locking member 14 and the lower part of the holding member 13 as seen in FIGS.
7 is an end view of the locking member 14, and FIG. 8 is a perspective view thereof. In this embodiment, the locking member 14 is formed by bending a rectangular aluminum plate along the longitudinal direction by press working, and a lower portion 35 for insertion into the pocket 18 and an upper portion 36 on which the holding member 13 is placed. It consists of. The thickness of the locking member 14 is about 2 mm, and the upper part 36 is bent from the lower part 35 by about 70 °. The dimension of the upper part 36 is set such that when the holding member 13 is placed on the locking member 14 in the frame member 11, the tip of the upper part 36 extends to the front of the groove 30 of the holding member 13. .
FIG. 9 shows an example of attachment of the plate suspension system of the present invention to the ceiling. A steel plate 40 is inserted into the frame member 11 below the engaging means 22, and the steel plate 40 is passed through a hole of a C-bar bracket 45 attached to the C-bar 42. The frame member 11 is installed by being suspended by 47. The frame member 11 is exposed under the ceiling (not shown), and all support structures above the frame member 11 are disposed on the back of the ceiling. The plate is attached by inserting the plate 12 having a plurality of holding members 13 bonded and fixed to the upper edge from the bottom of the frame member 11 and then placing the plate 12 in the pocket of the frame member 11 in advance from the insertion position of the holding member 13. The holding member 14 is slid downward (using an appropriate thin tool such as the tip of a driver) and then the holding member 13 is placed on the locking member 14.
FIG. 10 shows one mode of connection between the plate 12 suspended by the plate suspension system of the present invention and the wall surface 50 (the support structure behind the ceiling that supports the frame member 11 is omitted in the figure). ). In the figure, the plate 12 and the wall surface 50 are connected by a connecting member 52 made of flexible synthetic resin (soft vinyl chloride). FIG. 11 is a view when the vicinity of the lower end of the connecting member 52 is looked up obliquely from below. As shown in FIG. 11, the connecting member 52 includes a receiving portion 53 that sandwiches the edge portion of the plate 12 and a pair of flexible fin portions 55 a and 55 b that protrude from the back surface of the receiving portion. The fin portions 55a and 55b are bent in the lateral direction in the middle, and are adhered and fixed to the portion in close contact with the wall surface 50. The bottom 56 of the receiving portion 53 is separated from the wall surface 50 by interposing part of the fin portions 55a and 55b that have risen from now on. Thus, since the plate 12 and the wall surface 50 are connected to each other via the flexible connecting member 52 with a gap therebetween, a certain degree of mobility is ensured. This makes it possible to release stress generated in the connecting portion when shaking due to an earthquake or the like, and works to impart seismic isolation to the system. Even if the wall surface 50 is replaced with the side surface of another plate, the connecting member 52 can be used in exactly the same manner, and in this case, the same effect is exhibited.
FIG. 12 shows one mode of connection between adjacent edges of two plates 12a and 12b arranged at right angles, and 62 is a flexible connection member. FIG. 13 is a view when the vicinity of the lower end of the connecting member is looked up obliquely from below. In FIG. 13, the connecting member 62 sandwiches the edge portion of the plate 12 a by the receiving portion 63. The fin portion 65 rises from one place on the back surface of the receiving portion 63, and bends in the horizontal direction parallel to the plate 12b along the hinge portion 66, which is a V-shaped groove, and adheres to the contact surface with the plate 12b. It is fixed. Thus, since the plate 12a and the plate 12b are connected to each other via the flexible connecting member 62 with a gap therebetween, a certain degree of mobility is ensured. This also works to impart seismic isolation performance to the system in the event of shaking due to an earthquake or the like.
FIG. 14 is an enlarged view of the connecting member 52 shown in FIGS. 10 and 11 before being attached to the plate (the length is cut short). The connecting member 52 is manufactured by extrusion molding of soft vinyl chloride, and as shown in the figure, has a receiving portion 53 extending in the longitudinal direction and a pair of fin portions 55a and 55b protruding on the back side thereof. Yes. Hinge portions 56a and 56b, which are V-shaped grooves, are respectively formed in the middle of the width direction (projection direction) of the fin portion, and the fin portions 55a and 55b are either inside or outside at this portion.
