Description

[Technical Field]

[0001] The present invention relates to a panel mounting bracket, a panel mounting structure, and a panel mounting method, and more particularly to a panel mounting bracket, a panel mounting structure, and a panel mounting method for mounting a wall panel (partition wall panel) to the foundation of a building. [Background technology]

[0002] Conventionally, a construction method has been known in which a parting wall panel (for example, a lightweight aerated concrete panel) is attached to the foundation of a building in a raised state by using a combination of multiple mounting brackets and welding these mounting brackets to attach the parting wall panel to the foundation (for example, see Patent Document 1). The specific method for installing parting wall panels involves first welding an L-shaped angle to the top surface of the building's foundation, then welding a straight angle to the top surface of the foundation in a position opposite the L-shaped angle, and then welding a raising plate to the top of the straight angle.The parting wall panel is then erected against the foundation, and the Z-shaped rib clips that have been pre-attached to the parting wall panel are used to secure the panel so that the straight angle is sandwiched between them.The straight angle and rib clips are then welded together.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-332655 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned parting wall panel installation method, multiple mounting fixtures (L-shaped angles, ruler angles, raising plates, and rib clips) are placed between the foundation and the parting wall panel, and welding is performed at multiple locations to secure the parting wall panel to the foundation. Therefore, there has been a demand for improved workability and reduced labor and material costs. In addition, the anchor bolts were embedded in the top surface of the foundation so that they protruded, and depending on the placement of the mounting hardware and parting wall panels, there was a risk of interference with the anchor bolts.

[0005] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a panel mounting bracket, a panel mounting structure, and a panel mounting method that can improve workability and reduce labor costs and component costs. Another object of the present invention is to provide a panel mounting bracket, a panel mounting structure, and a panel mounting method that can reduce the number of parts of the mounting bracket used when mounting a parting wall panel to a foundation and reduce or eliminate welding work. [Means for solving the problem]

[0006] The above-mentioned problem is solved by a panel mounting fitting of the present invention, which is used to mount a wall panel along the upper surface of a foundation of a building, and which mounts the wall panel in a state in which it partially protrudes outward in the width direction of the foundation from the foundation, and which has: a first wall portion that abuts against a side surface of the foundation and extends in a vertical direction along the side surface; a second wall portion that abuts against a surface of the wall panel and extends in a vertical direction along the surface, and is continuous from the first wall portion via a connecting wall portion; and a protruding wall portion that extends horizontally from the connecting wall portion along the upper surface of the foundation and abuts against the upper surface of the foundation and the bottom surface of the wall panel, The first wall portion is formed with a foundation mounting portion that is mounted to a mounting portion provided on a side surface of the foundation, the second wall portion is formed with a panel assembly portion that is provided at a position higher than the foundation mounting portion and that is assembled to a mounting portion provided on a surface of the wall panel, and the protruding wall portion is formed with a panel support portion that is provided at a position between the foundation mounting portion and the panel assembly portion in the vertical direction and is interposed between the upper surface of the foundation and the bottom surface of the wall panel and supports the wall panel, and the protruding wall portion is provided on the upper surface of the connecting wall portion and protrudes horizontally from a portion that overlaps with the connecting wall portion and extends beyond the first wall portion. The panel mounting fixture is disposed at the center of the wall panel in the width direction, and the protruding wall portion is formed to be narrower than the first wall portion, the connecting wall portion, and the second wall portion, and the protruding wall portion is configured to abut against the bottom surface of the wall panel, and the connecting wall portion is configured not to abut against the bottom surface of the wall panel.This is solved by: The above-described configuration makes it possible to realize a panel mounting fixture that can improve workability and reduce labor and material costs. More specifically, the wall panel can be attached to the foundation using the panel mounting bracket, which allows for a significant reduction in the number of parts required for the mounting bracket compared to conventional examples. As described above, the panel mounting bracket utilizes the side of the foundation and has a foundation mounting portion that is attached to a mounting portion provided on the side of the foundation, and a panel support portion that is interposed between the top surface of the foundation and the bottom surface of the wall panel. Therefore, the panel mounting bracket is supported on the side and top surface of the foundation. This prevents the panel mounting bracket from rotating. It also provides the mounting bracket with the necessary functions of transmitting its own weight to the foundation and elevating the wall panel (rocking deformation function).

[0007] At this time, the protruding wall portion abuts against the inner surface of the second wall portion, and extends protruding from the inner surface of the second wall portion toward the first wall portion, and the protruding length of the protruding wall portion in the width direction of the foundation is longer than the connecting length of the connecting wall portion in the width direction of the foundation. The panel assembly portion is an assembly hole that is assembled with an assembly bolt into an assembly hole provided on the front or back surface of the wall panel, and the assembly hole is an elongated hole or a notched hole that extends longer in the width direction of the second wall portion than the assembly hole, and it is preferable that the wall panel is raised, thereby causing rocking deformation and suppressing damage to the wall panel.

[0011] The above problem is also solved by: the above A panel mounting method using a panel mounting bracket, comprising: a first step of attaching the panel mounting bracket to the foundation; a second step of placing the wall panel on the top surface of the foundation; and a third step of attaching the panel mounting bracket to the wall panel. In the first step, The aforementioned The second step is to attach a foundation mounting part, and the second step is to interpose the panel support part of the panel mounting bracket between the top surface of the foundation and the bottom surface of the wall panel, and the third step is to attach the panel mounting bracket to the front or back surface of the wall panel. The aforementioned This problem can also be solved by a panel mounting method in which a panel mounting portion is assembled. [Effects of the Invention]

[0012] The panel mounting fixture, panel mounting structure, and panel mounting method of the present invention make it possible to improve workability and reduce labor and material costs. Furthermore, the number of parts of the mounting fixtures used when mounting the parting wall panels to the foundation can be reduced, and welding work can be reduced or eliminated.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 9A and 9B. This embodiment relates to an invention of a panel mounting bracket for attaching a wall panel to the foundation of a building, the main feature of which is that it has a foundation mounting part that is attached to the side of the foundation, a panel assembly part that is located above the foundation mounting part and is assembled to the front or back surface of the wall panel, and a panel support part that is located between the foundation mounting part and the panel assembly part in the vertical direction, is interposed between the top surface of the foundation and the bottom surface of the wall panel, and supports the wall panel. The present invention also relates to a panel mounting structure and a panel mounting method.

[0015] The panel mounting structure of this embodiment is a building fitting structure in which a wall panel B5 (partition wall panel) is mounted in a raised state relative to the foundation B1 of a building B, as shown in FIGS. The panel mounting structure includes a reinforced concrete foundation B1 that serves as the base of building B, anchor bolts B2 embedded in the top surface of foundation B1, a base plate B3 connected to the top surface of foundation B1 by anchor bolts B2, a steel column B4 fixed on base plate B3 and supporting the superstructure of building B, and a plurality of wall panels B5 attached to the top surface of foundation B1. The wall panels B5 are each attached to the upper surface of the foundation B1 by panel mounting brackets 1 in a raised state. By raising the wall panel B5, for example, in the event of an earthquake, rocking deformation can be caused, thereby suppressing damage to the wall panel B5.

[0016] The foundation B1 has a mounting hole B1a formed on the side surface of the foundation B1 for mounting the panel mounting bracket 1. Specifically, the mounting hole B1a is an insert nut embedded in the side surface of the foundation B1. The wall panel B5 is a fire-resistant cementitious panel, for example an aerated concrete panel (ALC panel). The wall panel B5 has an assembly hole B5a formed on the surface of the wall panel B5 for assembling the panel mounting bracket 1. Specifically, the assembly hole B5a is an assembly anchor (vertical pipe) embedded inside the wall panel B5, and the assembly hole of the assembly anchor is exposed on the surface of the wall panel B5.

[0017] As shown in Figures 1 to 3, the panel mounting bracket 1 is a connecting bracket having a curved shape that is interposed between the foundation B1 and the wall panel B5 in the vertical direction and is used when mounting the wall panel B5 to the foundation B1. The specific shape of the panel mounting bracket 1 is a first wall portion 2 that abuts against the side surface of the foundation B1 and extends vertically along the side surface, a second wall portion 3 that abuts against the surface of the wall panel B5 and extends vertically along the surface, and a third wall portion 4 that abuts against the top surface of the foundation B1 and the bottom surface of the wall panel B5 and extends horizontally along the top surface of the foundation B1, connecting the first wall portion 2 and the second wall portion 3.

[0018] The second wall portion 3 is disposed so as to protrude outward beyond the first wall portion 2 in the thickness direction of the wall panel B5. Strictly speaking, the third wall portion 4 has a connecting wall portion 4a that connects the first wall portion 2 and the second wall portion 3 and extends horizontally, and a protruding wall portion 4b that is provided on the upper surface of the connecting wall portion 4a and protrudes from the inner surface of the second wall portion 3 toward the first wall portion 2 (foundation B1 side). The protruding wall portion 4b is disposed at the center of the panel mounting bracket 1 in the width direction, and is formed so as to be narrower than the first wall portion 2 and the second wall portion 3.

[0019] The specific functions of the panel mounting bracket 1 include a foundation mounting portion 10 formed on the first wall portion 2 and attached to the side surface (mounting hole B1a) of the foundation B1, a panel assembly portion 20 formed on the second wall portion 3 and attached to the surface (assembly hole B5a) of the wall panel B5, and a panel support portion 30 formed on the third wall portion 4 (protruding wall portion 4b) and supporting the wall panel B5.

[0020] The foundation mounting portion 10 is a mounting hole that is mounted to the side surface (mounting hole B1a) of the foundation B1 with a mounting bolt 11, and specifically, is an elongated hole that extends in the vertical direction. The panel mounting portion 20 is an assembly hole that is mounted to the surface (assembly hole B5a) of the wall panel B5 with an assembly bolt 21, and is specifically an elongated hole that extends along the width direction of the panel mounting bracket 1. The panel support portion 30 is a panel support surface of the third wall portion 4 (protruding wall portion 4b), and is formed in a substantially flat shape.

[0021] The above configuration makes it possible to realize a panel mounting fixture that can improve workability and reduce labor and material costs in a structure for mounting a wall panel to a foundation. In particular, compared to the conventional example, the number of parts for the mounting fixture is reduced to one, making it possible to eliminate the need for welding work.

[0022] <Panel mounting method> Next, a panel mounting method using panel mounting fixtures will be described. First, as shown in FIG. 4, the process starts with a "first process" (step S1) in which a worker attaches the panel mounting bracket 1 to the foundation B1. In this step, the foundation mounting portion 10 of the panel mounting bracket 1 is brought into contact with the side surface of the foundation B1, and the mounting bolts 11 are used to mount the panel.

[0023] Thereafter, a worker performs a "second process" in which the wall panel B5 is erected on the upper surface of the foundation B1 and the wall panel B5 is placed in a predetermined position (step S2). In this step, the panel support portion 30 of the panel mounting bracket 1 is interposed between the top surface of the foundation B1 and the bottom surface of the wall panel B5.

[0024] Thereafter, a worker performs a "third step" of attaching the panel mounting bracket 1 to the wall panel B5 (step S3). In this step, the panel assembly portion 20 of the panel mounting bracket 1 is brought into contact with the surface of the wall panel B5, and the panel is attached using the assembly bolts 21.

[0025] The above method makes it possible to realize a panel mounting method that can improve workability and reduce labor costs and material costs. In the above panel mounting method, the "first step", "second step", and "third step" do not necessarily have to be performed in the above steps. For example, the steps may be performed in the order of "third step," "second step," and "first step." That is, the panel mounting bracket 1 may be first attached to the surface of the wall panel B5, and then finally attached to the side surface of the foundation B1.

[0026] <Another embodiment of the panel mounting bracket> Next, second to fourth embodiments of the panel mounting bracket will be described with reference to FIGS. 5A and 5B to 7A and 7B. The description of the same content as that of the panel mounting bracket described above will be omitted.

[0027] As shown in Figures 5A and 5B, the panel mounting bracket 101 of the second embodiment has a specific shape including a first wall portion 102 that abuts against the side of the foundation B1 and extends vertically along the side, a second wall portion 103 that abuts against the surface of the wall panel B5 and extends vertically along the surface, and a third wall portion 104 that abuts against the top surface of the foundation B1 and the bottom surface of the wall panel B5 and extends horizontally along the top surface of the foundation B1, connecting the first wall portion 102 and the second wall portion 103. Strictly speaking, the third wall portion 104 has a connecting wall portion 104a that connects the first wall portion 102 and the second wall portion 103 and extends horizontally, and a protruding wall portion 104b that extends from the extending end of the connecting wall portion 104a so as to protrude further along the upper surface of the foundation B1. The protruding wall portion 104b is disposed closer to the center of the foundation B1 in the width direction than the second wall portion 103, and is interposed between the foundation B1 and the wall panel B5.

[0028] Specific functions of the panel mounting bracket 101 include a foundation mounting portion 110, a panel assembly portion 120, and a panel support portion 130 formed on the third wall portion 104 (protruding wall portion 104b). The foundation mounting portion 110 is an elongated hole extending in the width direction of the panel mounting bracket 1, and the panel assembly portion 120 is a notched hole extending in the vertical direction.

[0029] As shown in Figures 6A and 6B, the panel mounting bracket 201 of the third embodiment has a specific shape comprising a first wall portion 202 that abuts against the side surface of the foundation B1 and extends vertically along the side surface, a second wall portion 203 that abuts against the surface of the wall panel B5 and extends vertically along the surface and is continuous with the first wall portion 202, and a third wall portion 204 that extends horizontally from the connecting portion of the first wall portion 202 and the second wall portion 203 along the top surface of the foundation B1. The panel mounting bracket 201 also has a foundation mounting portion 210, a panel assembly portion 220, and a panel support portion 230 formed on the third wall portion 204. The foundation mounting portion 210 is a circular hole, and the panel assembly portion 220 is a notched hole extending in the vertical direction.

[0030] As shown in Figures 7A and 7B, the panel mounting bracket 301 of the fourth embodiment has a specific shape including a first wall portion 302 that abuts against the side of the foundation B1 and extends vertically along the side, a second wall portion 303 that abuts against the back surface of the wall panel B5 and extends vertically along the back surface, and a third wall portion 304 that abuts against the top surface of the foundation B1 and the bottom surface of the wall panel B5 and extends horizontally along the top surface of the foundation B1, connecting the first wall portion 302 and the second wall portion 303. The panel mounting bracket 301 also has a foundation mounting portion 310 , a panel assembly portion 320 , and a panel support portion 330 . The foundation mounting portions 310 are a plurality of circular holes, and the panel mounting portions 320 are cutout holes extending in the vertical direction.

[0031] <Second panel mounting bracket> Next, the second panel mounting bracket for mounting the wall panel B5 to the beam B6 of the building B will be described with reference to Figs. 8A and 8B to 9A and 9B.

[0032] As shown in Figures 8A and 8B, the second panel mounting bracket 50 is a connecting bracket having a curved shape, and specifically has a first wall portion 51 that abuts against the bottom surface of the beam B6 and extends horizontally along the bottom surface, a second wall portion 52 that abuts against the back surface of the wall panel B5 and extends vertically along the back surface and is continuous with the first wall portion 51, and a protruding wall portion 53 that protrudes upward from the connecting portion of the first wall portion 51 and the second wall portion 52 and abuts against the side surface of the beam B6. In addition, the second panel mounting bracket 50 has, as its specific functions, a beam mounting portion 60 that is attached to a mounting hole B7a provided on the bottom surface of a beam connecting member B7 provided on the beam B6, and a panel assembly portion 70 that is assembled to an assembly hole B5b provided on the back surface of the wall panel B5. The protruding wall portion 53 corresponds to a panel support portion that abuts against the rear surface of the wall panel B5 and the side surface of the beam B6, and functions to prevent the second panel mounting metal fitting 50 from rotating.

[0033] As an alternative to Fig. 8A, the second panel mounting bracket 50 may be attached directly to the beam B6, as shown in Fig. 8C. That is, the beam mounting part 60 may be attached to a mounting hole B6a provided on the bottom surface of the beam B6.

[0034] As shown in Figures 9A and 9B, the second panel mounting bracket 150 of the second embodiment has a specific shape comprising a first wall portion 151 that abuts against the bottom surface of the beam B6 and extends horizontally along the bottom surface, a second wall portion 152 that abuts against the back surface of the wall panel B5 and extends vertically along the back surface and is continuous with the first wall portion 151, and a protruding wall portion 153 that protrudes upward from the tip of the first wall portion 151 and abuts against the side surface of the beam. The second panel mounting metal fitting 150 also has a beam mounting portion 160 that is attached to a mounting hole B6a provided in the bottom surface of the beam B6, and a panel assembly portion 170. The protruding wall portion 153 is attached to the upper surface of the first wall portion 151, and is an abutment plate that abuts against the side surface of the beam B6, and corresponds to a beam support portion.

[0035] Even in the above-described other embodiment, it is possible to realize a panel mounting metal fitting (second panel mounting metal fitting) that can improve workability and reduce labor costs and material costs.

[0036] <Other embodiments> In the above embodiment, as shown in Figs. 1 and 2, the wall panel B5 is described as a "partition wall panel", but it is not particularly limited to a "partition wall panel" and can be widely applied. For example, the wall panel may be an "exterior wall panel" or an "interior wall panel" other than a parting wall panel.

[0037] In the above embodiment, as shown in FIG. 2, the foundation mounting portion 10 (panel assembly portion 20) is assembled using mounting bolts 11 (assembly bolts 21), but mounting means (assembly means) other than bolt fastening may also be used. For example, they may be attached by attachment means such as an engaging protrusion (fitting protrusion) and an engaging recess (fitting recess).

[0038] In the above embodiment, the panel mounting fixture, the panel mounting structure, and the panel mounting method according to the present invention have been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention naturally includes equivalents thereof. [Explanation of symbols]
