Description

Technical Field

[0001] The present invention relates to a mounting member for attaching a wall panel to a base metal fixed to a building body of a building, a mounting structure of the wall panel, a building, and a method for installing the wall panel.

Background Art

[0002] As a mounting structure for an ALC panel, a mounting structure (conventional structure 50 for a lightweight cellular concrete panel) as shown in FIG. 19 is widely adopted. In this mounting structure, an embedded anchor 52 embedded inside an ALC panel 51 and a panel joint surface of a lightning plate 53 used as a mounting fitting are joined by an anchor bolt 54. On the other hand, a base metal 56 having an L-shaped cross section joined to a building body 55 is sandwiched and fixed between the above panel joint surface of the lightning plate 53 and another surface formed to have a step by two-stage bending (Patent Document 1).

[0003] Here, regarding the embedding of the embedded anchor into the ALC panel, it is possible to embed it in advance in the panel manufacturing process, but in many cases, a hole is drilled and embedded using a general-purpose electric drill at the construction site.

[0004] When manually working at the site, if there is an error in the embedding position of the embedded anchor of the ALC panel, it may be difficult to install the ALC panel. If such an error can be absorbed by the mounting fitting, it is possible to reduce construction defects such as a wall structure using the ALC panel and improve the construction speed. Therefore, a mounting fitting capable of absorbing an error in the embedding position of the embedded anchor is required.

[0005] To meet such requirements, a mounting bracket has been proposed that consists of two brackets, a main plate and an auxiliary plate, each having a specific shape, and the auxiliary plate has a structure in which a protruding flat plate portion and protruding portions extending from both side edges of the protruding flat plate portion in the same direction and at the same height relative to the surface of the protruding flat plate portion (see Patent Document 2).

[0006] According to the mounting hardware disclosed in Patent Document 2, errors in the embedded anchor placement can be absorbed by the mounting hardware without changing the positional relationship between the ALC panel and the building structure, thereby eliminating the above-mentioned errors during the panel installation process.

[0007] [Patent Document 1] Japanese Patent Publication No. 2015-232219 [Patent Document 2] Patent No. 6405591 [Overview of the project] [Problems that the invention aims to solve]

[0008] Washers are sometimes placed between the mounting bracket and the panel, but these mounting brackets and washers are considered separate components. This requires extra effort to assemble them on-site, and the washers could fall off if, for example, the worker released their hand during installation. As a result, the washers had to be held in place at all times, hindering work efficiency.

[0009] Furthermore, in the mounting hardware described in Patent Document 2, the main plate and the auxiliary plate (washer) are integrated at the factory, but they cannot be separated at the construction site. Therefore, for example, if the thickness of the base metal is different, multiple types of mounting hardware must be prepared to match the thickness of the base metal. In addition, there was the problem of high costs due to the large number of metal parts, such as pins for integrating the main plate and the auxiliary plate.

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. [First Embodiment] The mounting member of the present invention is a mounting member for wall panels that attaches wall panels to a base metal fitting fixed to the building structure of a building. The mounting member of the present invention comprises a mounting bracket and a washer that is placed between the mounting bracket and the wall panel.

[0015] <Mounting hardware> Figure 1 is a perspective view showing one example of the configuration of the mounting bracket of the present invention, where (a) is a perspective view and (b) is a side view. Figure 2 is a diagram illustrating how the mounting bracket is butted against a base metal fitting. Figure 3 is a diagram illustrating the manufacturing method of the mounting bracket.

[0016] The mounting bracket 1 is a mounting bracket for attaching a wall panel (panel 20) to a base metal fitting 32 fixed to the building frame in the wall of a building, particularly an exterior wall, and is made of a bent metal plate. In this embodiment, the mounting bracket 1 is made of a bent metal plate that is roughly rectangular in shape (roughly rectangular in the example shown in Figure 3).

[0017] The mounting bracket 1 has a pair of first protruding pieces 3 formed by bending at both ends of a metal plate in a first direction parallel to one side (short side direction in the figure) at least a portion of the metal plate in a second direction perpendicular to the first direction (long side direction in the figure) at the same side and substantially perpendicular to one main surface of the metal plate; a substantially flat main body portion 2 disposed between the pair of first protruding pieces 3; and a projection portion that protrudes from the main body portion 2 on the opposite side from the bending direction of the first protruding pieces 3. The projection portion is equipped with a locking means that allows the mounting bracket 1 to be attached to the base metal fitting 32 at substantially a right angle.

[0018] In the example shown in Figure 1, the protruding portion has a pair of second protruding pieces 4, each formed by cutting a tongue-shaped section out of a metal plate and bending the tongue-shaped portion in the opposite direction to the bending direction of the first protruding piece 3.

[0019] In the example shown in Figure 3, a roughly rectangular metal plate is used, but a roughly square metal plate may also be used. Furthermore, in the following explanation, the first direction will be referred to as the "short side direction" and the second direction as the "long side direction." However, this is not limited to this, and the first direction may be the long side direction of the metal plate, and the second direction may be the short side direction of the metal plate. In the examples shown in Figures 1 to 3, the "long side direction" of the metal plate and the "long side direction" of the mounting bracket coincide, but this is not the only example.

[0020] The pair of first protruding pieces 3 are formed by bending at both ends of the metal plate in the short-side direction, with at least a portion of each piece in the long-side direction bent substantially perpendicular to one main surface of the metal plate on the same side. The mounting bracket 1 has first protruding pieces 3 that are bent on both sides, which ensures sufficient strength even when the metal plate is relatively thin.

[0021] In the example shown in Figure 1, the pair of first protruding pieces 3 are bent along their entire length in the long-side direction of the metal plate, but the design is not limited to this, and only a portion of the metal plate in the long-side direction may be bent. Furthermore, the first protruding pieces 3 may be formed not only at one location, but at multiple locations along the long-side direction of the metal plate.

[0022] The height (t1) of the first protruding piece 3 is not particularly limited, but from the viewpoint of strength and ease of processing during manufacturing, it is, for example, 10 mm to 15 mm.

[0023] The pair of second protruding pieces 4 are formed by cutting a tongue-shaped notch in a part of a metal plate, and bending the tongue-shaped portion on the opposite side of the bending direction of the first protruding piece 3 relative to one main surface of the metal plate.

[0024] Furthermore, in the mounting bracket 1 shown in Figure 1, the first protruding piece 3 and the second protruding piece 4, which are arranged on the same side in the short-side direction of the metal plate, are substantially on the same plane. Because the first protruding piece 3 and the second protruding piece 4 are substantially on the same plane, manufacturing by bending the metal plate is easy, and sufficient strength can be ensured.

[0025] Furthermore, in the mounting bracket 1 shown in Figure 1, the pair of second protruding pieces 4 are located at approximately the same distance from the end of the main body 2 that contacts the base metal fitting 32 in the longitudinal direction. Because the pair of second protruding pieces 4 are located at approximately the same distance from the longitudinal end of the main body 2, as shown in Figure 2, when attaching the mounting bracket 1 to the L-shaped base metal fitting 32, the side surfaces of the pair of second protruding pieces 4 can be brought into contact with the end of the base metal fitting 32, allowing the mounting bracket 1 to be positioned approximately perpendicular to the base metal fitting 32 easily and reliably, while also ensuring a certain length of overlap with the base metal fitting 32 (see Figure 9).

[0026] The distance (l) of the second protruding piece 4 from the longitudinal end of the main body 2 depends on the amount of engagement with the base metal fitting 32 (see Figures 2 and 9).

[0027] The height (t2) of the second protruding piece 4 is set so as not to exceed the thickness of the base metal fitting 32. The width (w) of the second protruding piece 4 is not particularly limited as long as the above function is ensured, but from the viewpoint of strength and ease of processing during manufacturing, it is, for example, 5 mm to 10 mm.

[0028] Thus, with this mounting bracket 1, in the wall panel installation method, the mounting bracket 1 can be easily and reliably attached to the base metal fitting 32 at approximately a right angle, and a consistent engagement area of ​​the mounting bracket 1 with the base metal fitting 32 can be ensured, thereby improving workability.

[0029] In the bent metal plate, the area between the pair of first protruding pieces 3 is a substantially flat main body portion 2, and the mounting bracket 1 is provided in the approximate center of the main body portion 2 and has an elongated hole 5 through which a bolt 26 for fixing the mounting bracket 1 to the panel 20 is inserted.

[0030] As shown in Figures 9 and 11 below, the elongated hole 5 is formed with a width that is sufficiently larger than the diameter of the bolt member (bolt 26) that screws into the anchor nut (O-nut 25) of the panel 20, and smaller than the diameter of the bolt member's head, and with a length predetermined in the design stage. By making the hole elongated rather than perfectly circular (elongated hole 5), misalignment of the anchor nut of the panel 20 can be absorbed.

[0031] The mounting bracket 1 may also have a slit 6 provided on one end of the main body 2 in the longitudinal direction. This slit 6 becomes a weld piece when the mounting bracket 1 is welded to the base metal 32.

[0032] By providing a slit 6 on one end of the mounting bracket 1, it becomes possible to weld the mounting bracket 1 from one direction while ensuring consistent quality. This allows, for example, in the case of horizontal wall construction, to be performed without changing the welding position, and in the case of vertical wall construction, it eliminates problems such as the welding rod not being able to reach the back of the column, making it possible to perform the work without having to go around the column.

[0033] The width of the slit 6 should be greater than or equal to the width into which the welding rod can be inserted, preferably 15 mm or more.

[0034] The length of the slit 6 depends on the engagement with the base metal fitting 32 (see Figures 9 and 10). If the slit 6 extends beyond the base metal fitting 32, a cross-sectional defect occurs, reducing the strength; therefore, the slit 6 must not extend beyond the base metal fitting 32. In the base metal fitting 32 of this embodiment, the engagement with the base metal fitting 32 is substantially equal to the distance (l) from the longitudinal end of the main body portion 2 of the second protruding piece 4. That is, the depth of the slit 6 from the longitudinal end of the main body portion 2 of the second protruding piece 4 does not exceed the distance (l) from the longitudinal end of the main body portion 2 of the second protruding piece 4.

[0035] Such mounting brackets 1 can be manufactured by cutting and bending a metal plate (sheet metal).

[0036] For example, first, a flat metal plate is prepared as shown in Figure 3. Then, the shaded portion in the figure is cut out to form the elongated hole 5 and the slit 6, and the plate is bent along the dotted line to form the first protruding piece 3 and the second protruding piece 4. By cutting a tongue-shaped notch in a part of the metal plate as shown in Figure 3, the first protruding piece 3 and the second protruding piece 4 can be formed in a single bending operation. This method makes processing easy and reduces costs. Of course, the first protruding piece 3 and the second protruding piece 4 can also be formed by separate operations.

[0037] The thickness of the metal plate constituting the mounting bracket 1 is preferably 3.0 mm or more, from the viewpoint of ease of processing and ensuring sufficient strength. However, it is not limited to this value.

[0038] In the above explanation, we used the example of a case where a slit 6 (notch) is formed on one end of the mounting bracket 1, but the present invention is not limited to this, and for example, the slit 6 may be omitted.

[0039] Furthermore, although the above description uses the case where only one slit 6 is formed as an example, the present invention is not limited to this, and for example, two or more slits 6 may be formed.

[0040] <Washer> Figure 4 shows one example of the configuration of a washer for mounting a wall panel according to this embodiment, where (a) is a perspective view, (b) is a top view, and (c) is a front view. Figure 5 shows the washer and mounting bracket combined in this embodiment, where (a) and (b) are perspective views and (c) is a front view. Figure 6 shows another example of the configuration of the washer according to this embodiment.

[0041] In the example shown in Figure 4, the washer 10 is made by bending a roughly rectangular metal plate, and has a pair of third protruding pieces 12 bent at both ends of the metal plate, on the same side and roughly perpendicular to one main surface of the metal plate, and a roughly flat washer body 11 positioned between the pair of third protruding pieces 12. In the example shown in Figure 4, a pair of notches 13 are formed on one end of the washer body 11 in the short side direction.

[0042] Each pair of third protruding pieces 12 has a narrow section where the width between the pair of third protruding pieces 12 is narrower. In the example shown in Figure 4, each of the pair of third protruding pieces 12 has a bent section 16 that is bent inward in a roughly "V" shape when viewed from the side, and the space between the pair of bent sections 16 is the narrow section. The dimensions of the narrow section, that is, the inner dimensions between the pair of bent sections 16, are slightly narrower than the outer dimensions of the mounting bracket 1.

[0043] As shown in Figure 5, the washer 10 is positioned along the side of the mounting bracket 1 where the elongated hole 5 is formed, rather than the side where the slit 6 is formed. The washer 10 is positioned such that a pair of third protruding pieces 12 overlap the outside of a pair of first protruding pieces 3 of the mounting bracket 1. This allows the washer 10 to be positioned relative to the mounting bracket 1 without bending or shifting.

[0044] At this time, when the pair of third protruding pieces 12 of the washer 10 are positioned to overlap the outside of the pair of first protruding pieces 3 of the mounting bracket 1, the pair of bent portions 16 come into contact with the outside of the pair of first protruding pieces 3 of the mounting bracket 1 and press against the first protruding pieces 3 from the outside. As a result, the mounting bracket 1 is sandwiched between the narrower portions of the washer 10.

[0045] As a result, even if the worker does not constantly hold the washer 10 against the mounting bracket 1 during installation, for example, if they release their hand during installation, the washer 10 will not fall off the mounting bracket 1. Consequently, work efficiency at the construction site can be improved.

[0046] Furthermore, since the mounting hardware and washers can be shipped pre-assembled at the factory, there is no need to assemble them at the construction site, reducing labor. As a result, work efficiency at the construction site can be improved.

[0047] Furthermore, even if the thickness of the base metal fittings 32 differs, it is possible to accommodate base metal fittings 32 of various thicknesses simply by changing the washer 10 at the construction site. In addition, because the mounting bracket 1 and the washer 10 are integrated, no parts such as pins are required, which leads to a reduction in the number of metal fittings and costs.

[0048] As shown in Figure 6, the washer 10 may have an open slit 17 instead of a closed hole 14 in the washer body 11. Because of its open shape, for example, when installing, even if the mounting bracket 1 and the washer 10 are overlapped and the bolt 26 is inserted through the bolt insertion holes (elongated holes 5 and slit 17), the position of the washer 10 can be adjusted by loosening the bolt.

[0049] Furthermore, it is preferable that one or more protrusions 15 are provided on the surface of the washer body 11 that contacts the mounting bracket 1, and that the sum of the thickness of the washer body 11 and the height of the protrusions 15 (t3) is approximately equal to the thickness of the base metal fitting 32. This allows the mounting bracket 1 (main body 2) to be fixed to the base metal fitting 32 so that the distance between it and the panel 20 is constant, that is, so that the mounting bracket 1 (main body 2) is approximately parallel to the panel 20.

[0050] The size, number, and arrangement of the protrusions 15 are not particularly limited; there may be one or two or more. In the example shown in Figure 4, one is placed on each side of the hole 14, but for example, as in the washer 10A(10) shown in Figure 12, three may be placed on each side of the hole 14.

[0051] These protrusions 15 are formed, for example, by a partial punching process. By forming the protrusions 15 by a partial punching process on the washer 10, the sum of the heights t3 of the protrusions 15 can be adjusted to be approximately equal to the thickness of the base metal fittings 32, even for base metal fittings 32 of different thicknesses. This makes it possible to install panels by changing the washer 10 placed between the mounting bracket 1 and the base metal fittings 32, even if the thickness of the base metal fittings 32 differs depending on the building part. Furthermore, for example, if the thickness of the washer body 11 alone can be made approximately equal to the thickness of the base metal fitting 32, then the protrusion 15 does not need to be formed.

[0052] <Wall panel installation method and installation structure> Next, a method and structure for mounting wall panels using the mounting members described above will be explained. The wall panel (panel 20) is, for example, an exterior wall panel, but the present invention is not limited to this. In the following explanation, the use of lightweight aerated concrete panels as wall panels is given as an example, but the present invention is not limited to this.

[0053] The wall panel mounting method of the present invention can be carried out in basically the same manner as the conventional wall panel mounting method, using the mounting bracket 1 and washer 10 described above. The wall panels may be vertical wall panels arranged so that the longer side of the wall panel is approximately vertical, or horizontal wall panels arranged so that the longer side is approximately horizontal. Basically, the mounting bracket 1 is attached to the panel such that the longitudinal direction of the mounting bracket 1 coincides with the longitudinal direction of the panel 20.

[0054] First, let's explain the wall panel (panel 20) that is attached to the building structure using mounting brackets. Figure 7 is a partial cross-sectional view showing one example of a wall panel configuration. Figure 8 is a perspective view showing one example of a locking hardware configuration. Panel 20 is not particularly limited; here, a lightweight aerated concrete panel is shown as an example, but it can also be applied to inorganic panels commonly used as building panels, such as cement-based extruded panels. The panel surface may be left unpainted or painted.

[0055] Elongated holes 21 are drilled from the end face of the panel 20 in a direction approximately perpendicular to the end face, and counterbore holes 22 are drilled from the surface of the panel 20 in a direction approximately perpendicular to the surface so as to connect the surface of the panel 20 with the elongated holes 21 (see Figure 7).

[0056] A rod-shaped or tubular steel material 23 is inserted into the elongated hole 21 from the end face of the panel 20, and a locking fitting 24 is inserted into the counterbore hole 22 from the surface of the panel 20. Inside the panel 20, the steel material 23 and the locking fitting 24 are engaged. As shown in Figure 8, the locking fitting 24 consists of an O-nut 25 having an engagement hole 25a, a bolt 26, and a washer 27. The steel material 23 is engaged with the engagement hole 25a of the O-nut 25 inside the panel 20.

[0057] An elongated hole 21 is drilled on the end face of the panel 20, approximately perpendicular to that face, and a counterbore hole 22 is drilled from the surface of the panel 20, reaching perpendicular to this face, to connect them. The elongated hole 21 and the counterbore hole 22 can be easily drilled with a handheld electric drill commonly used at construction sites, but they can also be drilled in advance during the panel manufacturing process. Next, the engagement hole 25a of the O-nut 25 of the locking fitting 24 is inserted into the elongated hole 21 from the counterbore hole 22, and the steel material 23 is inserted from the elongated hole 21 so as to pass through the engagement hole 25a. The length of the O-nut 25 is such that it does not reach the outside of the counterbore hole 22.

[0058] The diameter of the engagement hole 25a of the O-nut 25 is approximately equal to the outer diameter of the steel material 23, and the O-nut 25 and the steel material 23 engage and become one when the steel material 23 passes through the engagement hole 25a. The steel material 23 can be passed horizontally through a single panel 20, for example, at multiple positions on the top and bottom, and the locking fittings 24 can be attached in a vertical direction (the longitudinal direction of the panel) to fix the base metal fittings 32, and these can be increased as needed. Alternatively, the O-nut 25 may be positioned and fixed by welding to the reinforcing bars inside the panel 20. In that case, the steel material 23 and the engagement hole 25a can be omitted.

[0059] <Vertical wall construction method> Figure 9 is a perspective view showing one example of the wall panel mounting structure (vertical wall construction) of the present invention, and Figure 10 is a cross-sectional view. The wall panels are vertical wall panels arranged so that the longer side of each wall panel is approximately perpendicular to the wall.

[0060] The wall panel mounting structure is a wall panel mounting structure using the mounting bracket 1 described above, wherein at one end of the main body 2, the surface on which the second protruding piece 4 protrudes contacts the base metal fitting 32, and the mounting bracket 1 is arranged such that the side surfaces of each of the pair of second protruding pieces 4 abut against the base metal fitting 32.

[0061] The pair of second protruding pieces 4 of the mounting bracket 1 are located at approximately the same distance from the longitudinal end of the main body 2. This allows the mounting bracket 1 to be easily and reliably positioned at approximately a right angle to the base metal 32, even in locations where the bracket is difficult to directly see, by abutting the sides of the pair of second protruding pieces 4 against the end of the base metal 32 when attaching the mounting member to the base metal 32. Furthermore, by bringing the sides of the pair of second protruding pieces 4 into contact with the end of the base metal 32, a constant length can be ensured without the engagement area with the base metal 32 becoming larger or smaller. This also prevents the mounting bracket 1 from shifting during installation.

[0062] In this embodiment of the wall panel mounting structure, a washer 10 is placed between the wall panel (panel 20) and the mounting bracket 1.

[0063] As described above, the pair of third protruding pieces 12 of the washer 10 are positioned to overlap the outside of the pair of first protruding pieces 3 of the mounting bracket 1, and the pair of bent portions 16 contact the outside of the pair of first protruding pieces 3 of the mounting bracket 1 and press the first protruding pieces 3 from the outside. As a result, the mounting bracket 1 is sandwiched between the narrower portions of the washer 10.

[0064] As a result, even if the worker does not constantly hold the washer 10 against the mounting bracket 1 during installation, for example, if they release their hand during installation, the washer 10 will not fall off the mounting bracket 1. Consequently, work efficiency at the construction site can be improved.

[0065] If the washer body 11 has a notch 13, the pair of notches 13 are arranged to face the pair of second protruding pieces 4 of the mounting bracket 1. Furthermore, when the washer 10 is positioned at the outermost end (closest to the second protruding piece 4) relative to the mounting bracket 1, the pair of second protruding pieces 4 of the mounting bracket 1 and the pair of notches 13 of the washer 10 engage with each other. This allows the washer 10 to be positioned relative to the mounting bracket 1 without bending or shifting. Furthermore, it is sufficient that the washer 10 is in contact with the second projection 4, and it is not necessary for the washer body 11 to have a notch 13 formed therein.

[0066] Furthermore, the protrusion 15 provided on the washer body 11 allows the mounting bracket 1 (main body 2) to be fixed to the base metal fitting 32 so that it is substantially parallel to the panel 20.

[0067] The mounting bracket 1 has an elongated hole 5 located approximately in the center of the main body 2, and the washer 10 has a hole 14 located in the washer body 11. The mounting bracket 1 is positioned so that the elongated hole 5 and the hole 14 of the washer 10 overlap.

[0068] Then, the tip of the bolt 26 is inserted through the elongated hole 5 of the mounting bracket 1 and the hole 14 of the washer 10, and the bolt is screwed onto the O-nut 25 attached to the panel 20, thereby attaching the mounting bracket 1 to the panel 20 via the washer 10.

[0069] Furthermore, by placing the washer 10 between the panel 20 and the mounting bracket 1, when the mounting bracket 1 is attached to the panel 20, the embedded anchor (O-nut 25) and its embedded hole (countersunk hole 22) are less visible from the bolt insertion hole (elongated hole 5 and hole portion 14), thus maintaining aesthetic appeal.

[0070] Then, the mounting bracket 1, which has been pre-attached to the panel 20 as described above, is brought into contact with the base metal fitting 32, and the mounting bracket 1 is welded and fixed to the base metal fitting 32. In the examples shown in Figures 9 and 10, the mounting bracket 1 has a slit 6 formed on one end of the main body 2 in the longitudinal direction. The mounting bracket 1 is in contact with the base metal 32 on the side where the slit 6 is formed, and is fixed to the base metal 32 by welding at the portion of the slit 6.

[0071] At this time, since the pair of second protruding pieces 4 of the mounting bracket 1 are located at approximately the same distance from the longitudinal end of the main body 2, when attaching the mounting member to the base metal fitting 32, the side surfaces of the pair of second protruding pieces 4 abut against the end of the base metal fitting 32, making it easy and reliable to position the mounting bracket 1 at approximately a right angle to the base metal fitting 32, even in places where it is difficult to directly see the fitting (see Figure 2). In addition, by bringing the side surfaces of the pair of second protruding pieces 4 into contact with the end of the base metal fitting 32, a constant length can be ensured without the amount of contact with the base metal fitting 32 becoming larger or smaller. Furthermore, displacement of the mounting bracket 1 during the installation work is also prevented. This allows the panel 20 to be attached to the building structure.

[0072] <Horizontal wall construction method> Figure 11 is a perspective view showing one example of the configuration of the wall panel mounting structure (horizontal wall construction method) of the present invention. The wall panels are horizontal wall panels arranged so that the longer side of each wall panel is approximately horizontal. First, the mounting bracket 1 is attached to the panel 20 via the washer 10 by inserting the tip of the bolt 26 through the elongated hole 5 of the mounting bracket 1 and the hole 14 of the washer 10, and then screwing it onto the O-nut 25 attached to the panel 20.

[0073] Figure 11 shows an example of attaching the panel 20 to the column 30, which is part of the building's structural frame, using the mounting bracket 1. L-shaped base metal fittings 32 are welded to both sides of the column 30, which forms the vertically standing structural frame, via piece angles 31. Then, the mounting bracket 1, which has been previously attached to the panel 20 as described above, is brought into contact with the base metal fitting 32, and the mounting bracket 1 is welded and fixed to the base metal fitting 32 at the slit 6.

[0074] At this time, since the pair of second protruding pieces 4 of the mounting bracket 1 are located at approximately the same distance from the longitudinal end of the main body 2, when attaching the mounting bracket 1 to the base metal fitting 32, the side surfaces of the pair of second protruding pieces 4 abut against the end of the base metal fitting 32, making it easy and reliable to position the mounting bracket 1 at approximately a right angle to the base metal fitting 32, even in places where it is difficult to directly see the fitting. Furthermore, by bringing the side surfaces of the pair of second protruding pieces 4 into contact with the end of the base metal fitting 32, a constant length can be ensured without the engagement area on the base metal fitting 32 becoming larger or smaller. This also prevents the mounting bracket 1 from shifting during the installation process. In this way, the panel 20 is attached to the column 30.

[0075] According to the wall panel mounting method and mounting structure described above, sufficient strength can be ensured by the pair of first protruding pieces 3 of the mounting bracket 1. Furthermore, by bringing the pair of second protruding pieces 4 into contact with the base metal fitting 32, the mounting bracket 1 can be easily and reliably attached to the base metal fitting 32 at approximately a right angle, and a consistent engagement area of ​​the mounting bracket 1 with the base metal fitting 32 can be ensured, thereby improving workability.

[0076] In particular, for example, even if a worker lets go of the washer 10 during installation, it can be prevented from falling off the mounting bracket 1. As a result, work efficiency at the construction site can be improved.

[0077] [Second Embodiment] A second embodiment of the mounting member for wall panels of the present invention will be described. In the following description, we will mainly explain the parts that differ from the first embodiment, and the same reference numerals will be used for common parts, and their descriptions will be omitted. Figure 12 shows an example of the configuration of a washer related to the mounting member of the wall panel in this embodiment, where (a) is a perspective view and (b) is a front view. Figure 13 shows the washer and mounting bracket combined in this embodiment, where (a) is a perspective view and (b) is a front view.

[0078] The mounting bracket 1 has a structure similar to that shown in Figure 1, and comprises a pair of first protruding pieces 3 formed by bending at both ends in a first direction (short side direction in the figure) parallel to one side of the metal plate, with at least a portion of the second direction (long side direction in the figure) perpendicular to the first direction being bent substantially perpendicular to one main surface of the metal plate on the same side; a substantially flat main body portion 2 disposed between the pair of first protruding pieces 3; and a pair of second protruding pieces 4 projecting from the main body portion 2 in the direction opposite to the bending direction of the first protruding pieces 3.

[0079] The washer 10A(10) is made by bending a roughly rectangular metal plate, and has a pair of third protruding pieces 12 at both ends of the metal plate, each bent on the same side relative to one main surface of the metal plate, and a roughly flat washer body 11 positioned between the pair of third protruding pieces 12. A pair of notches 13 are formed on one end of the washer body 11 in the short side direction.

[0080] In particular, in the washer 10A(10) according to this embodiment, the pair of third protruding pieces 12 have a second engaging portion 18. The second engaging portion 18 is provided continuously from the pair of third protruding pieces 12 and is formed by bending inward or the like so that the width between the pair of second engaging portions 18 becomes narrower. The dimension between the pair of second engaging portions 18 is narrower than the outer dimensions of the mounting bracket 1. The distance between the pair of second engaging portions 18 is the distance between the tips of the second engaging portions 18.

[0081] The washer 10A(10) is positioned such that a pair of third protruding pieces 12 overlap the outside of the pair of first protruding pieces 3 of the mounting bracket 1. In this embodiment, the mounting member for the wall panel has a pair of second engaging portions 18 of the washer 10A(10) arranged to cover the upper ends of the pair of first protruding pieces 3 of the mounting bracket 1.

[0082] This allows the washer 10A(10) to be positioned more securely relative to the mounting bracket 1 without bending or shifting. Furthermore, the washer 10A(10) can be slid relative to the mounting bracket 1, allowing for optimal adjustment of the washer's position.

[0083] Furthermore, by positioning the pair of second engaging portions 18 of the washer 10A(10) to cover the upper end of the first protruding piece 3 of the mounting bracket 1, it is possible to prevent the washer 10 from falling off the mounting bracket 1 even if the user releases their hand during installation. As a result, work efficiency at the construction site can be improved.

[0084] Figure 14 shows another example of the washer configuration for the mounting member of this embodiment. For example, in the example shown in Figure 12, the second engaging portion 18 was bent at an angle to the third protruding piece 12, that is, the angle between the second engaging portion 18 and the third protruding piece 12 was obtuse. However, as shown in Figure 14(a), the second engaging portion 18 may be bent so that the angle between it and the third protruding piece 12 is approximately right angle.

[0085] Furthermore, in the example shown in Figure 12, the third protruding piece 12 was bent so as to be approximately perpendicular to the washer body 11. However, as long as the pair of second engaging portions 18 are arranged to cover the upper ends of the pair of first protruding pieces 3 of the mounting bracket 1, thereby preventing the washer 10 from falling off the mounting bracket 1, the third protruding piece 12 may be bent diagonally to the washer body 11, so that the angle between the washer body 11 and the third protruding piece 12 is obtuse, as shown in Figure 14(b).

[0086] Furthermore, in the example shown in Figure 12, the second engaging portion 18 was provided by bending it continuously from the third protruding piece 12. However, as shown in Figure 14(c), the second engaging portion 18 may be provided by rib processing, partial punching, or the like.

[0087] Figure 15(a) is a perspective view showing another embodiment of the mounting bracket, and Figure 15(b) is a perspective view showing the mounting bracket and washer combined. In the embodiment described above, the mounting bracket had a pair of first protruding pieces 3 that were bent substantially perpendicular to one main surface of a metal plate on the same side, and a substantially flat main body portion 2 disposed between the pair of first protruding pieces 3. However, the mounting bracket may not have the first protruding pieces 3.

[0088] In other words, the mounting bracket may consist of a main body 2 as a metal plate.

[0089] The washer 10A(10) is arranged such that the pair of third protruding pieces 12 and the pair of second engaging parts 18 cover both ends of the main body 2 of the mounting bracket in the short-side direction.

[0090] This allows the washer 10A(10) to be positioned more securely relative to the mounting bracket 1 without bending or shifting. Furthermore, the washer 10A(10) can be slid relative to the mounting bracket 1, allowing for optimal adjustment of the washer's position.

[0091] [Third Embodiment] A third embodiment of the mounting member for wall panels of the present invention will be described. In the following description, we will mainly explain the parts that differ from the embodiments described above, and the same reference numerals will be used for common parts, and their descriptions will be omitted. Figure 16 shows an example configuration of a mounting bracket related to the mounting member of this embodiment, where (a) is a perspective view and (b) is a front view. Figure 17 shows an example configuration of a washer related to the mounting member of this embodiment, where (a) is a perspective view, (b) is a top view and (c) is a front view. Figure 18 shows the washer and mounting bracket combined in this embodiment, where (a) is a perspective view and (b) is a front view.

[0092] As shown in Figure 16, the mounting bracket 1A(1) has a pair of first protruding pieces 3 formed by bending at both ends in a first direction (short side direction in the figure) parallel to one side of the metal plate, with at least a portion of the second direction (long side direction in the figure) perpendicular to the first direction being bent substantially perpendicular to one main surface of the metal plate on the same side; a substantially flat main body portion 2 disposed between the pair of first protruding pieces 3; and a pair of second protruding pieces 4 projecting from the main body portion 2 in the direction opposite to the bending direction of the first protruding pieces 3.

[0093] In particular, in the mounting bracket 1A(1) according to this embodiment, the pair of first protruding pieces 3 have a first engaging portion 7. The first engaging portion 7 is a protrusion formed on the first protruding piece 3 by rib processing, partial punching, etc., so as to protrude outward along the longitudinal direction of the main body portion 2.

[0094] As shown in Figure 17, the washer 10B(10) is made of a substantially rectangular metal plate that has been bent, and has a pair of third protruding pieces 12 that are bent substantially perpendicular to one main surface of the metal plate on the same side at both ends of the metal plate, and a substantially flat washer body 11 positioned between the pair of third protruding pieces 12. A pair of notches 13 may be formed on one end of the washer body 11 in the short side direction.

[0095] In particular, in the washer 10B(10) according to this embodiment, the pair of third protruding pieces 12 have a third engaging portion 19. The third engaging portion 19 is a protrusion formed on the third protruding piece 12 by bending or the like so as to protrude outward.

[0096] Then, as shown in Figure 18, the washer 10B(10) is positioned such that a pair of third protruding pieces 12 overlap the outside of the pair of first protruding pieces 3 of the mounting bracket 1A(1). At this time, the pair of first engaging parts 7 of the mounting bracket 1A(1) and the pair of third engaging parts 19 of the washer 10B(10) engage.

[0097] This allows the washer 10B(10) to be positioned more securely on the mounting bracket 1A(1) without bending or shifting. Furthermore, the first engaging portion 7 acts as a rail, allowing the washer 10B(10) to slide relative to the mounting bracket 1A(1). This allows for precise adjustment of the washer's position. Additionally, it prevents the washer 10B(10) from falling off the mounting bracket 1A(1) even if the user releases their hand during installation. As a result, work efficiency at the construction site can be improved.

[0098] Furthermore, the scope of the present invention also extends to building construction methods for buildings that incorporate the wall panel installation method described above.

[0099] Furthermore, the scope of the present invention extends to buildings equipped with the wall panel mounting structure described above.

[0100] While embodiments of the present invention have been described above, the present invention is not limited thereto and can be modified as appropriate without departing from the spirit of the invention.

[0101] For example, in the embodiment described above, the main body portion 2 of the mounting bracket 1 was described using the example where the shape of the end opposite to the side that abuts against the base metal is substantially rectangular, as shown in Figure 1. A rectangular shape includes, for example, the shape shown in Figure 12 of Japanese Patent Application No. 2022-032890. However, the present invention is not limited thereto, and for example, the end of the main body portion opposite to the side that abuts against the base metal may be curved or have a shape with large chamfered corners.

[0102] Furthermore, in the embodiments described above, the washer 10 was explained using the case where the washer body 11 is rectangular, as shown in Figure 4. However, the present invention is not limited to this, and for example, a washer 10' with a substantially semicircular washer body 11 can also be used. Of course, the shape of the washer body 11 may also be circular or polygonal. [Industrial applicability]

[0103] By using the mounting member according to the present invention, processing is easy, the mounting bracket can be attached to the base metal at approximately a right angle, and a consistent engagement area for the mounting bracket with the base metal can be ensured, resulting in improved workability. It can be widely used as a mounting member for attaching wall panels, a mounting structure for wall panels, and a building and wall panel mounting method. [Explanation of Symbols]
