Description

  The present invention relates to a fireproof partition wall, a construction method thereof, and a panel body form used for the fireproof partition wall.

  In buildings such as high-rise houses, hotels, hospitals, etc., the separation and walls of adjacent rooms are constructed by attaching fire-resistant partition walls using fire-resistant boards typified by gypsum boards, not on-site concrete walls. It has become common.

  The construction method of a fireproof partition wall using a fireproof board excellent in cost, fireproof performance and sound insulation performance is to erected a stud as a base pillar between the lower surface of the slab or the lower surface of the beam and the upper surface of the floor slab. A stud type that attaches a fireproof board (for example, refer to Patent Document 1), and a runner is attached to the lower surface of the slab or the lower surface of the beam and the upper surface of the floor slab. Non-stud type (see, for example, Patent Document 2).

  Further, in the non-stud type, a wall surface is constructed by arranging a plurality of fireproof boards having a plurality of panels formed in a hollow multi-layer structure between spacers and reinforcing materials between upper and lower runners (for example, Patent Document 3). And 4).

  However, in the stud type described in Patent Document 1, work such as erection of a plurality of studs at predetermined positions between the lower surface of the slab or the lower surface of the beam and the upper surface of the floor slab, and alignment of the fireproof board with respect to the erection dimension Therefore, not only is it difficult to shorten the construction period, but also there is a problem that the cost is high because a professional worker is required. Further, when wiring and piping work is necessary, the work must be performed in the middle of the construction of the partition wall, so that the work is likely to be more complicated.

  In the non-stud type described in Patent Document 2, it is necessary to ensure the strength for self-supporting a fire-resistant board having a built-in height dimension of 2 m to several tens of cm to more than 3 m. It has the disadvantage that the length of the board is limited. Further, when a gypsum board is used as a fireproof board, if the gypsum board is made to stand on its own by a non-stud type, unevenness due to deformation such as bending or twisting tends to occur, which has a drawback of affecting the finish aesthetics.

  In the non-stud type using the shaped panel body described in Patent Documents 3 and 4, there is not only an error of about ± several cm between the lower surface of the slab or the lower surface of the beam and the upper surface of the floor slab, but also the surface is not smooth. Therefore, when using a standardized panel body, if the built-in dimension is larger than the design dimension, a gap is generated, and therefore it is necessary to fill the gap. Work such as shaving is required, and fine adjustment at the site of the panel body is complicated, and the workability is reduced. Further, fine adjustment work at the site has the disadvantage that individual differences in finishing are likely to occur depending on the skill of the operator, and it is difficult to make the finished aesthetics uniform.

  Therefore, the problem of the present invention is that it is possible to construct a partition wall without requiring skill, and it is possible to shorten the construction period and reduce the cost, and to obtain a uniform finish aesthetics and its construction. It is an object of the present invention to provide a form of a panel body used for a law and a fireproof partition wall.

  After the panel body is attached, the gap which is the open part can be closed by attaching a lower fireproof board and an upper fireproof board as a post process. Therefore, it is possible to close the gap that is an open part while proceeding with each work such as building the partition wall by installing the panel body, wiring and piping work, filling with heat insulating material, etc. Work becomes possible.

In particular, according to the first aspect of the present invention, the panel body constituting the partition wall is composed of substantially all or the main part of the lower and upper fireproof boards attached to one side of the panel body, and the other side. The lower and upper refractory boards are attached to the upper and lower parts with a gap that becomes an open part, so that most of them are already installed with the lower and upper refractory boards. Because it is formed as a standardized panel body, even if it is a standardized panel body that can obtain a uniform finish aesthetics, fine adjustment work on the spot that requires skill is unnecessary, and the gap part is Simple work is possible because it is only necessary to install the underlay fireproof board and the upholstery fireproof board by the conventional method on site.

Therefore, according to the first aspect of the present invention, the partition wall can be constructed without requiring skill, the construction period can be shortened and the cost can be reduced, and a homogeneous finish can be obtained.

According to the second aspect of the present invention, the joint of the lower fireproof board and the joint of the upper fireproof board are provided at positions where they do not overlap, thereby providing fire resistance (preventing transmission of fire and smoke). In addition, the sound insulation (sound transmission preventing property) is improved, and the adjacent fireproof boards adjacent to each other of the panel bodies arranged side by side can be integrated by the upper fireproof board, so that the strength can be reinforced.

According to the third aspect of the present invention, instead of attaching the bottom fireproof board and the top fireproof board to the structure one by one, the structure after the bottom fireproof board and the top fireproof board are aligned. By fixing to the body at the same time, work efficiency can be improved.

According to the inventions shown in claims 4 to 7 , a uniform shape is achieved by the form of the panel body in which the underlaying fireproof board and the upholstery fireproof board are attached to at least two studs standing at predetermined intervals. A panel body can be obtained easily. In particular, when attaching the bottom fireproof board and the top fireproof board to the stud, the bottom fireproof board and the top fireproof board are aligned rather than attaching the bottom fireproof board and the top fireproof board one by one to the structure. By attaching it to the structure at the same time, the work efficiency can be improved.

  Hereinafter, the details of the present invention will be described with reference to the accompanying drawings.

  The fireproof partition wall 1 is configured by arranging a plurality of panel bodies 10... (Only two are shown in FIG. 1).

  As shown in FIGS. 2 and 3, the panel body 10 is provided on substantially the entire one surface side of the structure body having the upper and lower runners 11, 12 and at least two studs 13, 13. The lower fire board 14 and the upper fire board 15 are attached, and the lower fire board 14 and the upper fire board 15 are attached to the upper and lower portions on the other side of the structure with a gap 16 as an open portion. The gap 16 which is the open part of the upper part and the lower part on the other surface side is configured to be closed by the rear mounting of the underlaying fireproof board 14 and the upholstery fireproof board 15.

  The panel body 10 constitutes a panel body (end panel) 10 </ b> A (see FIG. 2) that constitutes one end portion of the partition wall 1 in contact with the one wall surface 4 and other than one end portion of the partition wall 1. And a panel body (basic panel) 10B (see FIG. 3).

  The runners 11 and 12 and the studs 13 used in the present invention are known and publicly used runners (for example, a hot-dip galvanized copper strip or copper strip having a U-shaped cross section) and studs used for this type of fire-resistant partition wall. For example, a hot dip galvanized copper plate column or a copper plate column having a square cross section can be used.

  As the underlay fireproof board 14 used in the present invention, a publicly known fireproof board (for example, a gypsum board) used as an underlay fireproof board of this kind of fireproof partition wall can be used.

  As the upper fireproof board 15 used in the present invention, a publicly known fireproof board (for example, a reinforced gypsum board) used as an upper fireproof board of this type of fireproof partition wall can be used.

The lower fireproof board 14 and the upper fireproof board 15 are attached to the structure having the runners 11 and 12 and the stud 13 after the lower fireproof board 14 and the upper fireproof board 15 are aligned. It is fixed to the stud 13 by screwing . By co-bis beating, working efficiency as compared with the method that has been attached by Tucker a veneer fireproof board underlayment fireproof board after first screw striking secure the underlayment fireproof board to conventional not high.

  The runners 11 and 12 may be attached to the stud 13 after the attachment to the bottom fireproof board 14 and the top fireproof board 15 to the stud 13 or one of the upper and lower sides (for example, the upper runner 11). Only the upper fireproof board 14 and the upper fireproof board 15 may be attached after attaching only the stud 13 to the stud 13, and then the other upper and lower (for example, the lower runner 12) may be attached to the stud 13. The assembly procedure may be changed as appropriate according to the construction site to be installed. However, after assembling the parts other than the upper runner 11 in advance and measuring and checking the dimensional height of the housing at the installation position, the length of the stud 13 It is preferable to adjust the height and then attach the upper runner 11 since it can cope with the error of the installation position.

Of the panel body 10, first, the panel body (end panel) 10A will be described.
Since the panel body (end panel) 10A constitutes one end portion of the fireproof partition wall 1 as described above, the end portion on the side in contact with the wall surface 4 as shown in FIG. 2 (a) {FIG. 2 (a) In FIG. 2, on the right side, the studs 13, the runners 11 and 12 {not shown in the plan view of FIG. 2A}, the ends of the underlaying fireproof board 14 and the upholstery fireproof board 15 are flush with each other. It is arranged as follows.

  As shown in FIG. 2 (c), the lower fireproof board 14 and the upper fireproof board 15 are attached to substantially the entire one surface of the panel body (end panel) 10A by means such as screwing. Substantially all (specifically, preferably up to half of the stud 13) is the side that does not contact the wall surface 4 (the right side of the drawing in FIG. 2C), that is, the panel body (basic panel). This is to prevent the joints at the end portion on the side where 10B is arranged side by side between the stud 13 and the underlay fireproof board 14. Further, the side of the upper refractory board 15 that is not in contact with the wall surface 4 is further displaced so as not to coincide with the joints of both the stud 13 and the lower refractory board 14. Studs 13, runners 11 and 12 {not shown in the plan view of (a)} for the upper end portion in contact with the slab lower surface or beam lower surface 2 and the lower end portion in contact with the floor slab upper surface 3 The boards 14 are aligned so that all ends of the upper fireproof board 15 on one side are flush with each other.

  Next, as shown in FIG. 2 (b), on the other surface side of the panel body (end panel) 10A, the lower fireproof board 14 and the upper fireproof fireproof with a gap 16 serving as an open portion in the upper part and the lower part. The board 15 is attached by means such as screwing.

  By providing the opening 16 as a gap, when the panel body (end panel) 10A is attached to the lower surface of the slab or the lower surface 2 of the beam and the upper surface 3 of the floor slab, the upper and lower runners 11 and 12 are opened. 16, the runners 11 and 12 can be nailed.

  The side not touching the wall 4 on the other side {the left side in the drawing in Fig. 2B), that is, the end on the side where the panel body (basic panel) 10B is juxtaposed is the one side described above. Similarly to the above, in order to prevent the joints from being coincident with each other between the stud 13 and the underlay fireproof board 14, a portion where the half of the stud 13 is hidden is attached. Further, the upper fireproof board 15 is further displaced so that the side not in contact with the wall surface 4 does not coincide with the joints of both the stud 13 and the lower fireproof board 14 in the same manner as the one side described above.

  With respect to the upper end portion and the lower end portion of the lower side fireproof board 14 and the upper side fireproof board 15 on the other surface side, by providing a gap 16 serving as an open portion, the gap 16 serving as the open portion is provided by post-attachment as a post process. A joint is generated by plugging. Accordingly, the upper refractory board 15 is attached to the lower refractory board so that the joint does not coincide with the lower refractory board 14 at the upper end and the lower end.

  With respect to the positions of the upper end portion and the lower end portion of the lower fireproof board 14 and the upper fireproof board 15, the upper end and the lower end are attached without gaps on one surface side, and there are gaps 16 serving as open portions above and below on the other surface side. The configuration provided and attached is clearly shown in FIG.

  In the panel body (end panel) 10A of this embodiment, three studs 13 are provided for the side that is in contact with the wall surface 4, for the middle, and for the portion that handles the joint portion of the joint end of the panel body (basic panel) 10B. It has been. The gap between the studs 13, 13, and 13 is filled with a heat insulating material as necessary so as to satisfy various regulations such as required fire prevention standards. As a heat insulating material to be used, a publicly known heat insulating material (for example, glass wool etc.) used for this kind of fireproof partition wall can be used. The heat insulating material may be filled during the manufacture of the panel body 10 or may be post-filled from the gap 16 serving as the open portion. The gap 16 serving as the open portion can be used not only for filling with a heat insulating material but also when wiring and piping are necessary.

Next, the panel body (basic panel) 10B will be described with reference to FIG.
As described above, the panel body (basic panel) 10B constitutes a portion other than one end portion of the fireproof partition wall 1, and a plurality of panel bodies (end panel) 10A are arranged in parallel and continuously connected. By proceeding {see FIG. 4 (a) and FIG. 4 (b)}, it is possible to construct the fireproof partition wall 1 for the length of the juxtaposition. That is, one panel body (end panel) 10A is used for one fireproof partition wall 1, whereas the panel body (basic panel) 10B corresponds to the length (width) of the fireproof partition wall 1. Thus, a plurality of sheets having the same configuration are used.

  The left and right end portions of the panel body (basic panel) 10B are joined so that a plurality of sheets having the same configuration can be continuously arranged and connected in accordance with the length (width) of the fireproof partition wall 1 to be constructed. At this time, the stud 13, the underlaying fireproof board 14, and the upholstery fireproof board 15 are attached to each other so as to have irregularities matching each other. And since the edge part which becomes concave has the structure which corresponds to the convex of the connection edge part of 10 A of panel bodies (end part panel), the edge part which becomes the convex of panel body (basic panel) 10B is a panel body ( The end panel has the same configuration as the protruding end of 10A.

  The specific mounting positions of the stud 13, the lower fireproof board 14, and the upper fireproof board 15 will be described. As described above, the connecting fired board 14 of the panel body (end panel) 10 </ b> A extends to the half of the stud 13. Is attached, and the upper fireproof board 15 displaced from the lower fireproof board 14 is attached, so that the upper end of the connecting end portion of the panel body (basic panel) 10B becomes concave so as to coincide with this displacement. The tension fireproof board 15 is attached so as to be shifted from the underlay fireproof board 15 so as to protrude in the connecting direction.

  Other configurations other than the connecting end portion that becomes the recess of the panel body (basic panel) 10B have the same configuration as the panel body (end panel) 10A described above. Accordingly, the upper and lower ends of the lower fire-resistant board 14 and the upper fire-resistant board 15 are also attached to the upper and lower ends without any gaps as shown in FIGS. 3 (c) and 3 (d). As shown in FIGS. 3 (b) and 3 (d), the other surface side has a configuration in which a gap 16 serving as an open portion is provided above and below and attached.

As mentioned above, although the fireproof partition wall 1 used for this invention was demonstrated, the panel body (end part panel) 10A and the panel body (basic panel) 10B which comprise the fireproof partition wall 1 are one or several kinds of standardized dimensions. Can be manufactured in advance in a factory or the like, and can be selected and used according to the building to be applied. In particular, since many buildings such as high-rise houses, hotels, and hospitals have uniform ceiling heights, standardization is extremely effective in terms of cost reduction and work efficiency. In the case of non-standard, it may be dealt with by correction at the site or manufacturing at the site, or when the quantity is large, it may be dealt with by pre-manufacturing at a factory or the like.

  By standardizing the panel body (end panel) 10A and the panel body (basic panel) 10B, the studs 13, the bottom fireproof board 14 and the top fireproof board 15 to be used are ordered and manufactured in advance. Therefore, the cost can be further reduced. In addition, by standardization, it is possible to order / manufacture a laminate and superposed refractory board 14 and upper refractory board 15 of dimensions applicable to the standard in a state where they are pre-aligned in a factory or the like. Manufacturing efficiency can be increased.

  Next, an embodiment of a construction method for constructing the fireproof partition wall 1 using the panel body (end panel) 10A and the panel body (basic panel) 10B having the above-described configuration will be described below.

  First, a panel body (end panel) 10A is arranged at a portion in contact with the wall surface 4 at the installation position, and after confirming the position with reference to laser and pre-printing, the upper and lower sides of the panel body (end panel) 10A The runners 11 and 12 are fixed to the lower surface of the slab or the lower surface of the beam 2 and the upper surface 3 of the floor slab using a nailing machine from the gap 16 serving as an open portion.

  Next, as shown in FIG. 4 (a), a panel body (basic panel) 10B is arranged next to the fixed panel body (end panel) 10A, and the position is confirmed with reference to laser and prior ink marking. Then, the upper and lower runners 11 and 12 of the panel body (basic panel) 10B are fixed to the lower surface of the slab or the lower surface of the beam 2 and the upper surface 3 of the floor slab using a nailing machine from the gap 16 serving as an open portion. Further, the lower fire-resistant board 14 and the upper fire-resistant board 15 of the panel body (basic panel) 10B located at the connection portion between the panel body (end panel) 10A and the panel body (basic panel) 10B are connected to the panel body (end panel). ) It is fixed to the stud 13 of 10A and the underlayer fireproof board 14 by fixing means such as a screw or a tucker {see FIG.

  Next, as shown in FIG. 4A and FIG. 4B, the panel bodies (basic panels) 10B corresponding to the designed number are successively opposed to the wall surface 4 next to the fixed panel body (basic panel) 10B. The refractory partition wall 1 can be constructed by installing and fixing in parallel until it comes into contact with the side in contact with the wall surface or pillar.

  After or during construction of the refractory partition wall 1, filling with heat insulating material and wiring / piping work are performed as necessary, and then open portions that exist laterally above and below the other side of the refractory partition wall 1 An operation for closing the gap 16 is performed. The closing operation is performed by attaching the underlaying fireproof board 14 and the upholstery fireproof board 15 in accordance with the size of the gap 16 serving as the open portion to the location by a fixing means such as a screw or a tucker.

  Moreover, about the panel body (basic panel) 10B finally installed and fixed, a half of the stud 14 and a part of the underlay fireproof board 14 at the end portion on the side in contact with the wall surface and the pillar facing the wall surface 4 are exposed. In this state, the bottom fireproof board 14 and the top fireproof board 15 that match the dimensions of this portion are attached to the corresponding portions by fixing means such as screws or tuckers. By this operation, the entire surface of the constructed fireproof partition wall 1 is double fireproof coated by the lower fireproof board 14 and the upper fireproof board 15.

  After the installation of the lower fireproof board 14 and the upper fireproof board 15 on the entire surface of the fireproof partition wall 1, the ground treatment and finishing process for finishing the surface of the fireproof partition wall 1 are performed.

As mentioned above, although one Example of the construction method of the fireproof partition wall 1 which concerns on this invention was described, this invention is not limited to the above, Other various aspects can also be taken.

  For example, when applied to a place where the ceiling height is higher than a general dimension, for example, as shown in a panel body (end panel) 10A ′ in FIG. It is preferable that the lower fireproof board 14 and the upper fireproof board 15 have a general height dimension attached. Since fireproof boards such as gypsum boards are relatively heavy, mounting underlay fireboards 14 and upholstery fireproof boards 15 that fit the height of the high ceiling increases the weight and can be transported to the construction site. Since installation becomes difficult, it is possible to prevent these difficulties by adopting a configuration for mounting a general height. In this configuration, the upper end portions of the lower fire board 14 and the upper fire board 15 on one side are attached so that the joints are not aligned. With this configuration, a gap 16 ′ serving as a large open portion is formed in the upper portion on both sides of the one side and the multi-sided side, and the gap 16 ′ serving as the open portion is also a post-mounting step as in the above-described embodiment. In this case, the lower fire board 14 and the upper fire board 15 corresponding to the size of the gap 16 'serving as the open portion may be attached and closed.

Next, the formwork of the panel body used for a fireproof partition wall is demonstrated below.
The panel body (end panel) 10A and the panel body (basic panel) 10B described above are assembled while being aligned with the design dimensions, but the formwork was used by standardizing the dimensions. Manufacture is possible.

  First, the formwork for the panel body (end panel) 10A is a formwork (No. 1) 17A for determining the position of the stud 13 and attaching the underside fireproof board 14 and the upside fireproof board 15 on one side (No. 1) (FIG. 6) and a formwork (part 2) 18A (see FIG. 7) for mounting the remaining fireproof board 14 and the upper fireproof board 15 on the opposite surfaces.

  As shown in FIG. 6, the mold frame (No. 1) 17A has stud positioning concave grooves 19, 19, 19 for determining the positions of the three studs 13, 13, 13 standing at predetermined intervals. An end positioning portion (No. 1) 20 of the underlaying fireproof board 14 and the upholstery fireproof board 15 is provided at the end of the formwork (No. 1) 17A.

  First, using the formwork (part 1) 17A, the studs 13, 13, and 13 are fitted into the stud positioning grooves 19, 19, and 19 of the formwork (part 1) 17A, and then the underlay fireproof board 14 is inserted. Is placed on the end positioning portion (part 1) 20 with the end protruding, and then the upper fireproof board 15 is placed on the end positioning portion (part 1) 20 with the end protruding. By screwing and fixing with a screw driving machine or the like, attachment on one side (either one side or the other side) is completed.

  Next, using the formwork (part 2) 18A shown in FIG. 7, one side of the opposite side (either the other side or the one side) is attached.

  As shown in FIG. 7, the formwork (part 2) 18A has a stepped portion of the upper form fireproof board 15 as the surface of the bottom fireproof board 14 and the upper fireproof board 15 attached to the formwork (part 1) 17A enters. A recess 21 having a step 21A corresponding to the step and a step 21B corresponding to the step of the underlayer fireproof board 14 is provided, and the end positioning portion (No. 1) 20 is provided at one end of the recess 21. Similarly, an end positioning part (part 2) 22 for determining the end positions of the lower fireproof board 14 and the upper fireproof board 15 is provided.

  The one side, which is the surface on which the lower fireproof board 14 and the upper fireproof board 15 have been attached, is fitted into the recess 21 in the formwork (part 1) 17A, and then the lower fireproof board 14 is fitted to the end positioning part (part 2). ) 22 with the end projecting, and then the upper fireproof board 15 is placed with the end projecting on the end positioning part (Part 2) 22 and then fixed with a screwing machine or the like. This completes the installation of the opposite surface.

  When mounting the opposite surface, before the underlaying fireproof board 14 is placed, the filler 5 can be filled if necessary.

  As described above, first, using the formwork (part 1) 17A and then using the formwork (part 2) 18A, each dimension such as the distance between the studs 13, 13, and 13 is measured each time.
