Description

Technical Field

[0001] [[ID=???]]This invention relates to a mounting fitting for a wall panel for attaching a wall panel forming a wall surface such as a retaining wall to a support member and a wall panel.

Background Art

[0002] A construction method of constructing a retaining wall or the like by stacking wall panels to form a wall surface is known. For example, in Patent Document 1, a remaining formwork is arranged on the surface side of a slope of cut soil and fill soil using a coupler, and the coupler for connecting adjacent remaining formworks is fixed to a column member installed on the slope side via a separator, and then, backfill concrete is placed in a gap between the remaining formwork and the slope, and a construction method of a cantilever retaining wall is disclosed.

[0003] However, in the disclosed technique of Patent Document 1, it is necessary to connect the remaining formworks adjacent to each other vertically, horizontally, and diagonally with a coupler provided on the back surface of the remaining formwork. For this reason, the remaining formwork must be arranged in consideration of the position of a fixing object on the slope side to which the coupler is fixed via a separator or the like, and the adjustable range of the position of the remaining formwork is narrow. In particular, in the curve construction of an inclined wall surface, since the wall surface extension changes for each step number of the remaining formwork, it is very difficult to arrange the remaining formwork following the change in the wall surface extension with the remaining formwork having a fixed coupler fixing position. For this reason, in curve construction or the like, the remaining formwork itself needs to be cut and adjusted, and the position adjustment and reinforcement of the fixing metal fitting are required, etc., and the work efficiency is very low, and a high level of skill is required for construction.

[0004] It should be noted that there is an unclear tag "??? " in the translation of line 5. Please double-check the original text for accuracy. If it's a misprint or an unclear notation in the original, appropriate corrections should be made for a more precise translation.On the other hand, as a technique to broaden the adjustable range of the position of the wall material, a wall panel is disclosed in Patent Document 2. The wall panel in Patent Document 2 is a substantially rectangular parallelepiped wall panel for stacking to form the outer surface of a wall, and is equipped with guide runners that engage with adjacent wall panels and hooks that connect the wall panel to a separator fixed to a fixed object, wherein the guide runners are provided in two or more locations near the top and bottom edges of the wall panel, and the hooks are provided independently of the guide runners at appropriate locations on the back surface of the wall panel.

[0005] According to the wall panel described in Patent Document 2, the wall panel can stand independently by having its guide runners contact the back surface of adjacent wall panels, without being connected to them. This allows for a wide range of adjustment for the wall panel's position, and is said to improve the efficiency of readjusting the position and orientation of the wall panel.

[0007] Incidentally, the wall panel in Patent Document 2 has guide runners and hooks embedded in it, each independently constructed. The semicircular feet formed at both ends of the hooks are secured to metal reinforcement embedded inside the wall panel to prevent the hooks from coming out of the wall panel. Therefore, in order to embed the guide runners and hooks into the wall panel beforehand when manufacturing the wall panel in Patent Document 2, the material of the panel body must be a molded product such as concrete. For this reason, the wall panel in Patent Document 2 cannot be made of stone or wood, and is subject to material limitations.

[0008] Therefore, the present invention was devised in view of the above-mentioned problems, and its objective is to provide a mounting bracket for wall panels for attaching a support member to a wall panel, which can be easily attached to a wide variety of wall panels and allows for easy adjustment of the position of the wall panels when stacking them, as well as a wall panel having this mounting bracket. [Means for solving the problem]

[0009] The mounting bracket for a wall panel according to the present invention is a mounting bracket for a wall panel for attaching a wall panel to a support member, comprising: a bracket body having a flat plate portion that contacts the back surface of the wall panel and has a first through hole, and a guide plate portion formed by bending from the flat plate portion; and a bolt that is inserted into the first through hole and fixes the flat plate portion to the back surface of the wall panel, wherein the guide plate portion has an opposing portion that faces the back surface of the wall panel, and a back projection that extends from the opposing portion so as to extend beyond the side surface of the wall panel and to contact the back surface of another wall panel adjacent to the wall panel, and at least one of the bolt and the opposing portion has a second through hole formed for fixing to the support member.

[0010] The wall panel according to the present invention is characterized by having mounting hardware for the wall panel according to the present invention. [Effects of the Invention]

MODE FOR CARRYING OUT THE INVENTION

[0013] Hereinafter, an example of a mounting bracket for a wall panel as an embodiment of the present invention and a wall panel having this mounting bracket will be described with reference to the drawings.

[0014] <First Embodiment> As shown in FIG. 1, the mounting bracket 1 for a wall panel is for connecting and fixing a rectangular parallelepiped wall panel 10 to a support member 8 and mounting it. Hereinafter, the mounting bracket 1 for a wall panel will also be simply referred to as the mounting bracket 1.

[0015] Multiple wall panels 10 are stacked to form the wall surface of a wall structure 100, such as a retaining wall. The wall structure 100 is composed of multiple stacked wall panels 10, support members 8 provided on the wall panels 10, wall panels 9 provided on the support members 8, etc. The support members 8 support the wall panels 10 and are composed of, for example, a support column 81, a support fitting 82, and a backfill material 83. The backfill material 83 is, for example, concrete. The wall panels 10 are used as residual formwork panels that hold the concrete used as the backfill material 83 when it is poured. The backfill material 83 may be made of concrete, or other materials such as crushed stone, soil, cement improver, etc.

[0016] The support column 81 is erected, for example, on a foundation, and is made of L-shaped angle material or the like.

[0017] The support bracket 82 is a well-known rod-shaped separator used to maintain the position of the wall panel 10 when concrete is poured as backfill material 83. The support column 81 and the support bracket 82 are embedded in the backfill material 83.

[0018] The wall panel 9 is, for example, a conventional wooden formwork. The wall panel 9 is supported by a support member 8. The wall panel 9 is fixed to a support column 81 via a separator 85 provided on the back. The separator 85 is embedded in the backfill material 83.

[0019] As shown in Figure 2, one end of the support bracket 82 has a hook portion 84 formed by bending a rod-shaped member, and the hook portion 84 is hooked onto the mounting bracket 1. The other end of the support bracket 82 is fixed to the support column 81 by fastening fittings such as welding or bolts and nuts. The support bracket 82 may be a rod-shaped round separator or a plate-shaped plate separator.

[0020] As shown in Figures 2 and 3, the wall panel 10 is made of a stone material such as natural stone for the panel body, but the panel body may also be made of concrete, wood, or the like. The wall panel 10 is formed in the shape of a rectangular parallelepiped, and has a front 10a, a back 10b, and four sides 10c, 10d, 10e, and 10f. The front 10a of the wall panel 10 is formed in an uneven shape and constitutes the outer surface of the wall structure 100. Four mounting brackets 1 are attached to the back 10b of the wall panel 10. The two sides 10c and 10e of the wall panel 10 are long sides and constitute the upper and lower sides. The two sides 10d and 10f of the wall panel 10 are short sides and constitute the left and right sides.

[0021] Of the four mounting brackets 1 attached to one wall panel 10, the two mounting brackets 1a and 1b positioned on the upper side have rear projections 24 (described later) that extend from the opposing portion 23 so as to extend beyond the upper side surface 10c of the wall panel 10. The two mounting brackets 1c and 1d positioned on the lower side have rear projections 24 (described later) that extend from the opposing portion 23 so as to extend beyond the lower side surface 10e of the wall panel 10.

[0022] As shown in Figure 4, the mounting bracket 1 comprises a bracket body 2 and a bolt 3. In Figure 4, among the stacked wall panels 10, the wall panel to which the mounting bracket 1 is attached is designated as wall panel 10-1, and the other wall panel 10 adjacent to wall panel 10-1 is designated as wall panel 10-2. In Figure 4, the mounting bracket 1 on wall panel 10-2 is not shown.

[0023] The metal fitting body 2 has a flat plate portion 21 that contacts the back surface 10b of the wall panel 10-1 and has a first through hole 20, and a guide plate portion 22 that is formed by bending from the flat plate portion 21. The first through hole 20 is formed, for example, in a circular shape.

[0024] The guide plate portion 22 has an opposing portion 23 that faces the back surface 10b of the wall panel 10-1, and a back projection 24 that extends from the opposing portion 23 so as to extend beyond the upper side surface 10c of the wall panel 10-1 and to contact the back surface 10b of another wall panel 10-2 adjacent to the wall panel 10-1.

[0025] The opposing portion 23 has a second through-hole 25 formed therein for hooking and securing the hook portion 84 of the support bracket 82. The second through-hole 25 is for securing the support bracket 82. When the hook portion 84 is hooked and secured in the second through-hole 25, the other end of the support bracket 82 can move vertically and horizontally with the hook portion 84 as a pivot point, making it easier to adjust the position of the other end of the support bracket 82, which is welded to the support column 81, in the vertical and horizontal directions.

[0026] Although not shown in the illustration, the support bracket 82 may be fixed to the mounting bracket 1 by fastening fittings such as bolts and nuts placed in the second through hole 25. When the support bracket 82 is fixed to the second through hole 25 via fastening fittings such as bolts and nuts, the support bracket 82 can be rotated vertically around the bolts and nuts, making it easier to adjust the position of the other end of the support bracket 82 welded to the support column 81 in the vertical direction.

[0027] The bolt 3 is, for example, an anchor bolt embedded in the wall panel 10. The extension line C1 of the axis of the bolt 3 and the extension line C2 of the center of the second through hole 25 intersect. As a result, the support bracket 82, which is hooked into the second through hole 25, is positioned to hold the head of the bolt 3, thus preventing the bolt 3 from coming out. Even if the bolt 3 loosens due to vibrations from a vibrator or the like when pouring the concrete backfill material 83, the support bracket 82 prevents the bolt 3 from coming out, resulting in a safe installation.

[0028] The tip of the rear projection 24 has a projection 26 that protrudes toward the rear surface 10b of the other wall panel 10-2. The projection 26 can contact the rear surface 10b of the other wall panel 10-2. The projection 26 is formed by the end face of the rear projection 24 protruding. The two corners of the projection 26 each have chamfered portions 26a, forming a trapezoidal shape when viewed from the normal direction of the guide plate portion 22. By bringing the chamfered portions 26a into contact with the other wall panel 10-2, the inclination of the other wall panel 10-2 with respect to the vertical can be finely adjusted. The chamfered portions 26a may have an arc shape or the like.

[0029] The rear projection 24 has a notch 27 formed below the projection 26. Therefore, when backfill material 83 is installed, the backfill material 83 can be installed in the notch 27 between the back surface 10b of the wall panel 10 and the rear projection 24. Therefore, even if rainwater or the like penetrates from between wall panel 10-1 and wall panel 10-2, the backfill material 83 can prevent the penetrating rainwater from reaching the rear projection 24. Therefore, corrosion of the rear projection 24 due to the penetration of deterioration factors such as rainwater can be suppressed.

[0030] The bolt 3 is inserted into the first through hole 20 and fixes the flat plate portion 21 to the back surface 10b of the wall panel 10. There is one bolt 3 in each mounting bracket 1. Having one bolt 3 allows the guide plate portion 22 to rotate around the bolt 3 when the bolt 3 is loosened. This allows for fine adjustment of the position of the back projection portion 24 that contacts other wall panels 10-2.

[0031] As shown in Figure 1, the wall panels 10 positioned at the bottom and top of the wall structure 100 are provided with mounting brackets 11. The mounting bracket 11 comprises a bracket body 2 and a bolt 3. The bracket body 2 of the mounting bracket 11 has a flat plate portion 21 and a guide plate portion 22. The guide plate portion 22 has an opposing portion 23, and the rear projection portion 24 is omitted.

[0032] Next, an example of a method for constructing a wall structure 100 using a wall panel 10 having a mounting bracket 1 will be described.

[0033] The method for constructing the wall structure 100 includes, for example, a column installation step, a wall panel installation step, a support bracket installation step, and a backfill material installation step. The order of the column installation step and the wall panel installation step is arbitrary.

[0034] The support column installation process involves installing support columns 81.

[0035] The wall panel installation process involves stacking multiple wall panels 10 on the front side of the support column 81 to install the wall panels 10. The wall panels 10 are stacked, for example, along a roughly vertical direction.

[0036] As shown in Figure 5, the wall panel installation process involves installing the first layer of wall panels 10, and then installing the second layer of wall panels 10 above the first layer of wall panels 10. More specifically, as shown in Figure 5(a), the wall panel installation process involves positioning the second layer of wall panels 10 above the first layer of wall panels 10. As shown in Figure 5(b), the wall panel installation process involves moving the second layer of wall panels 10 above the first layer of wall panels 10 vertically downwards. As shown in Figure 5(c), the wall panel installation process involves placing the second layer of wall panels 10 on top of the first layer of wall panels 10. This allows the wall panels 10 to be stacked.

[0037] As shown in Figure 6, the stacked wall panels 10 are arranged, for example, in a staggered pattern vertically. Furthermore, the wall panels 10 are stacked horizontally so that the upper side 10c and the lower side 10e are horizontal.

[0038] As shown in Figure 6(a), when the wall panels 10 are stacked vertically, the rear projection 24 of the mounting bracket 1 of the lower wall panel 10 contacts the rear surface 10b of the upper wall panel 10. Similarly, the rear projection 24 of the mounting bracket 1 of the upper wall panel 10 contacts the rear surface 10b of the lower wall panel 10. As shown in Figure 6(b), when the wall panels 10 are stacked vertically, the upper wall panel 10 tends to tilt towards the front surface 10a, but this movement is prevented by the guide plate portion 22, where the rear projection 24 contacts the rear surfaces 10b of each other. This ensures the flatness of the upper and lower wall panels 10 in the thickness direction, and the relative positions in the thickness direction are temporarily fixed by the guide plate portion 22 when they are stacked.

[0039] As shown in Figure 7, since adjacent wall panels 10 are not connected to each other, the upper wall panel 10 can be moved left or right (in the direction of arrow P in Figure 7) even after the upper wall panel 10 has been placed on the lower wall panel 10. Therefore, it is easy to adjust the position of the wall panels 10 when stacking them.

[0040] Furthermore, in the construction of inclined walls, it becomes easier to construct wall structures 100 that require positional adjustment of wall panels 10, such as continuous construction of inner curves, outer curves, and inner and outer curves.

[0041] In addition, the tip of the rear projection 24 has a projection 26 that protrudes toward the rear 10b side of the other wall panel 10. This allows for fine adjustment of the inclination of the other wall panel 10 with respect to the vertical direction when the projection 26 comes into contact with it. This makes it easier to adjust the position of the wall panel 10. Furthermore, the corners of the projection 26 are chamfered. This allows for fine adjustment of the inclination of the other wall panel 10 with respect to the vertical direction when the chamfered corners of the projection 26 come into contact with it. This makes it even easier to adjust the position of the wall panel 10.

[0042] Furthermore, as shown in Figure 6(a), during the wall panel installation process, the main body of the fitting 2 is rotated around the bolt 3 (in the direction of arrow R in the figure). This finely adjusts the position of the rear projection 24 that contacts other wall panels 10, thereby determining the position of the wall panels 10.

[0043] In addition, during the wall panel installation process, the wall panel 9 is installed on the back side of the support column 81.

[0044] Then, after determining the position of the wall panel 10, as shown in Figures 2 and 4, in the support bracket installation process, the hook portion 84 formed on one end of the support bracket 82 is hooked into the second through hole 25, and the other end of the support bracket 82 is fixed to the support column 81, for example, by welding or bolts and nuts.

[0045] In the support bracket installation process, the wall panel 9 is fixed to the support column 81 via the separator 85.

[0046] The wall panel installation process and the support bracket installation process are repeated until wall panel 10 and wall panel 9 are stacked to a predetermined height.

[0047] Then, as shown in Figure 1, in the backfill material installation process, after stacking the wall panels 10 and 9 to a predetermined height, concrete 83 is poured between the wall panels 10 and 9 as backfill material.

[0048] This completes one example of a method for constructing the wall structure 100.

[0049] According to this embodiment, a bolt 3 is provided that is inserted into the first through hole 20 and fixes the flat plate portion 21 to the back surface 10b of the wall panel 10. This allows the mounting bracket body 2 to be attached to the panel body of the wall panel 10 later. For this reason, it can be attached not only if the material of the panel body of the wall panel 10 is concrete, but also if it is made of natural stone. Therefore, the mounting bracket 1 can be easily attached to the wall panel 10.

[0050] According to this embodiment, the guide plate portion 22 has an opposing portion 23 that faces the back surface 10b of the wall panel 10, and a back projection portion 24 that extends from the opposing portion 23 so as to extend beyond the side surface of the wall panel 10 and to contact the back surface 10b of other wall panels 10 adjacent to the wall panel. As a result, when the wall panels 10 are stacked vertically, the upper wall panel 10 tends to tilt towards the front surface 10a, but this movement is prevented by the guide plate portion 22, where the back projection portion 24 contacts the back surfaces 10b of each other, the tilt of the upper and lower wall panels 10 is adjusted, and the relative positions in the thickness direction are temporarily fixed by the guide plate portion 22 when they are stacked.

[0051] Since adjacent wall panels 10 are not connected to each other, even after placing the upper wall panel 10 on top of the lower wall panel 10, the upper wall panel 10 can be moved left or right (in the direction of arrow P in Figure 7). Therefore, it is easy to adjust the position of the wall panels 10 when stacking them.

[0052] Furthermore, in the construction of inclined walls, it becomes easier to construct wall structures 100 that require positional adjustment of wall panels 10, such as continuous construction of inner curves, outer curves, and inner and outer curves.

[0053] According to this embodiment, the opposing portion 23 has a second through-hole 25 for hooking the support fitting 82. As a result, when a tensile force from the support fitting 82 acts on the fitting body 2, the bending moment acting on the fitting body 2 can be reduced compared to the case where the second through-hole 25 is provided in the rear projection 24. Therefore, damage to the fitting body 2 can be suppressed.

[0054] In this embodiment, the extension line C1 of the axis of the bolt 3 and the extension line C2 of the center of the second through hole 25 intersect. As a result, the support bracket 82 is positioned to hold the head of the bolt 3, thus preventing the bolt 3 from coming loose. Even if the bolt 3 loosens due to vibrations from a vibrator or the like when the backfill material 83 is poured, the support bracket 82 prevents it from coming loose, resulting in a safe installation.

[0055] According to this embodiment, there is only one bolt 3. This allows the metal fitting body 2 to rotate around the bolt 3 provided on the main body of the wall panel 10 when the bolt 3 is loosened. Therefore, the position of the rear projection 24 that contacts the back surface 10b of another wall panel 10 can be finely adjusted.

[0056] According to this embodiment, the tip of the rear projection 24 has a projection 26 that protrudes toward the rear 10b side of the other wall panel 10. This allows for fine adjustment of the inclination of the other wall panel 10 with respect to the vertical direction when the projection 26 comes into contact with it. This makes it easier to adjust the position of the wall panel 10. Furthermore, the corners of the projection 26 are chamfered. This allows for fine adjustment of the inclination of the other wall panel 10 with respect to the vertical direction when the chamfered corners of the projection 26 come into contact with it. This makes it even easier to adjust the installation position of the wall panel 10.

[0057] In the embodiments described above, the wall panel 10 was described in a case where it is installed, for example, along a substantially vertical direction. In the present invention, as shown in Figure 8, the wall panel 10 may be installed at an inclination with respect to the vertical direction, for example. The wall panel 10 is spaced apart from the ground 91. Support columns 81 are erected between the wall panel 10 and the ground 91. Backfill material 83 is poured between the wall panel 10 and the ground 91.

[0058] In this case, as shown in Figure 9, in the wall panel installation process, the first wall panel 10 is installed at an inclination with respect to the vertical, and then the second wall panel 10 is installed above the first wall panel 10. More specifically, as shown in Figure 9(a), in the wall panel installation process, the second wall panel 10 is positioned above the first wall panel 10. As shown in Figure 9(b), in the wall panel installation process, the second wall panel 10 above the first wall panel 10 is moved vertically downward. As shown in Figure 9(c), in the wall panel installation process, the second wall panel 10 is tilted to the rear and placed on top of the first wall panel 10. This allows the wall panels 10 to be stacked at an inclination with respect to the vertical.

[0059] In the embodiments described above, the case in which the wall panels 10 are stacked flat so that their bottom surfaces are horizontal was explained. In the present invention, as shown in Figure 10, the wall panels 10 may be stacked in a valley stack so that their bottom surfaces are inclined at approximately 45° with respect to the horizontal.

[0060] In this case, as shown in Figure 11, for example, six mounting brackets 1 are attached to the back surface 10b of the wall panel 10.

[0061] Of the six mounting brackets 1 attached to one wall panel 10, the two mounting brackets 1a and 1b positioned on the upper side have rear projections 24 that extend from the opposing portion 23 so as to extend beyond the upper side surface 10c of the wall panel 10. The two mounting brackets 1c and 1d positioned on the lower side have rear projections 24 that extend from the opposing portion 23 so as to extend beyond the lower side surface 10e of the wall panel 10. The two mounting brackets 1e and 1f positioned on the left and right sides have rear projections 24 that extend from the opposing portion 23 so as to extend beyond the left and right sides 10d and 10f of the wall panel 10.

[0062] Thus, if the wall panel 10 has a rear projection 24 that extends beyond the long side and a rear projection 24 that extends beyond the short side, it can be stacked in a valley pattern.

[0063] In the embodiments described above, the wall panel 10 was explained as having a rectangular parallelepiped shape as an example. However, in the present invention, the wall panel 10 may not be rectangular parallelepiped, but may be formed into a random shape with irregular shapes and sizes. In this case, the wall panels 10 can be stacked randomly.

[0064] <Second Embodiment> Next, the mounting bracket 1 in the second embodiment will be described. Detailed explanations of the same configuration as in the above-described embodiment will be omitted below. As shown in Figure 12, a pair of rear projections 24 are formed. The bracket body 2 has a flat plate portion 21 that contacts the back surface 10b of the wall panel 10 and has a first through-hole 20, and a guide plate portion 22 that is formed by bending the flat plate portion 21.

[0065] The guide plate portion 22 has a pair of opposing portions 23 and a pair of rear projections 24. The pair of opposing portions 23 are arranged opposite each other and parallel to each other. The pair of rear projections 24 are arranged opposite each other and parallel to each other. A second through hole 25 is formed in each of the pair of rear projections 24.

[0066] <Third Embodiment> Next, the mounting bracket 1 in the third embodiment will be described. As shown in Figure 13, a pair of rear projections 24 are formed. The bracket body 2 has a flat plate portion 21 that is in contact with the back of the wall panel 10 and has a first through hole 20, and a guide plate portion 22 that is formed by bending from the flat plate portion 21.

[0067] The guide plate portion 22 has an opposing portion 23 and a pair of rear protrusions 24.

[0068] The opposing portion 23 has an upright plate portion 23a bent from the flat plate portion 21, and a first opposing portion 23b and a second opposing portion 23c bent from the upright plate portion 23a in different directions. The first opposing portion 23b and the second opposing portion 23c are extended in directions that are 90° apart when viewed from the normal direction of the flat plate portion 21.

[0069] The rear projection 24 has a first rear projection 24a extending from the first opposing portion 23b and a second rear projection 24b extending from the second opposing portion 23c. The first rear projection 24a extends from the first opposing portion 23b so as to extend beyond the long side of the wall panel 10, for example. The second rear projection 24b extends from the second opposing portion 23c so as to extend beyond the short side of the wall panel 10, for example.

[0070] As shown in Figure 14, the wall panels 10 may be stacked in a valley stack so that their bottom surfaces are inclined relative to the horizontal. Thus, the wall panels 10 can be stacked in a valley stack if they have a rear projection 24 that extends beyond the long side and another rear projection 24 that extends beyond the short side.

[0071] <Fourth Embodiment> Next, the mounting bracket 1 in the fourth embodiment will be described. As shown in Figure 15, an eye bolt is used for the bolt 3. The bolt 3, as an eye bolt, has a head that is formed in an annular shape. A second through hole 31 is formed in the head of the bolt 3 for hooking and fixing the hook portion 84 of the support bracket 82. The second through hole 31 is for fixing the support bracket 82.

[0072] According to this embodiment, the bolt 3 has a second through-hole 31 for fastening the support bracket 82. This reduces the bending moment acting on the bracket body 2 even when a tensile force from the support bracket 82 acts on the bolt 3. As a result, damage to the bracket body 2 can be suppressed.

[0073] Although not shown in the diagram, the support bracket 82 may be fixed to the mounting bracket 1 by fastening fittings such as bolts and nuts placed in the second through hole 31.

[0074] <Fifth Embodiment> Next, a wall structure 100 using a wall panel 10 having a mounting bracket 1 according to the fifth embodiment will be described. As shown in Figure 16, in the wall structure 100, the support member 8 has an existing retaining wall 87 instead of a support column 81. For example, a steel pipe pile is used as the existing retaining wall 87. Although not shown in the figures, the existing retaining wall 87 may be a steel sheet pile, a steel pipe sheet pile, or the like.

[0075] <Sixth Embodiment> Next, a wall structure 100 using a wall panel 10 having a mounting bracket 1 according to the sixth embodiment will be described. As shown in Figure 17(a), in the wall structure 100, one end of the support bracket 82 is hooked onto the wall panel 10. The other end of the support bracket 82 is provided with a locking portion 86, which is formed by attaching a flat plate. Since the locking portion 86 is embedded in the backfill material 83, the wall panel 10 can be held in a predetermined position by the support bracket 82.

[0076] When constructing this wall structure 100, the first layer of wall panels 10 and the support columns 81 are fixed together via support brackets 82. Then, the first layer of backfill material 83a is installed between the first layer of wall panels 10 and the ground 91.

[0077] If the backfill material 83 is concrete, after the first layer of backfill material 83a has hardened, the second layer of wall panels 10 is stacked on top of the first layer of wall panels 10. Then, the second layer of backfill material 83b is poured between the second layer of wall panels 10 and the ground 91. The second layer of backfill material 83b is poured to a height below the mounting bracket 1 on the upper side of the second layer of wall panels 10 so that the mounting bracket 1 is exposed from the backfill material 83b. Then, before the backfill material 83b hardens, one end of the support bracket 82 is hooked onto the mounting bracket 1 that is exposed from the backfill material 83b. With one end hooked, the support bracket 82 is rotated so that the locking portion 86 at the other end of the support bracket 82 is embedded in the backfill material 83b before it hardens. With the locking portion 86 embedded in the backfill material 83b, the backfill material 83b is hardened. This fixes the position of the wall panels 10.

[0078] The same procedure as described above can be used for the third layer of wall panels 10 and the third layer of backfill material 83c. In this way, the backfill material 83 may be poured after the wall panels 10 have been stacked one layer high.

[0079] If the backfill material 83 is crushed stone or the like, after installing the first layer of backfill material 83a, the second layer of wall panels 10 is stacked on top of the first layer of wall panels 10. Then, the second layer of backfill material 83b is installed between the second layer of wall panels 10 and the ground 91. The second layer of backfill material 83b is installed to a height below the mounting bracket 1 on the upper side of the second layer of wall panels 10 so that the mounting bracket 1 on the upper side of the second layer of wall panels 10 is exposed from the backfill material 83b. Then, one end of the support bracket 82 is hooked onto the mounting bracket 1 that is exposed from the backfill material 83b. With one end hooked, the support bracket 82 is rotated so that the locking portion 86 on the other end of the support bracket 82 is embedded in the backfill material 83b. This fixes the position of the wall panels 10.

[0080] <Seventh Embodiment> Next, a wall structure 100 using a wall panel 10 having a mounting bracket 1 according to the seventh embodiment will be described. As shown in Figure 17(b), in the wall structure 100, one end of the support bracket 82 is hooked onto the wall panel 10. The locking portion 86 at the other end of the support bracket 82 may be formed by bending a rod-shaped support bracket 82.

[0081] <Eighth Embodiment> Next, a wall structure 100 using a wall panel 10 having a mounting bracket 1 in the eighth embodiment will be described. As shown in Figure 18, the wall structure 100 is a stone wall in a castle or the like. The wall structure 100 is constructed by stacking wall panels 10 made of stone materials such as natural stone. The wall structure 100 has a slope that becomes steeper as it goes upwards, for example, due to the stacked wall panels 10.

[0082] As shown in Figures 19(a) and 19(b), the wall panel 10 is made of stone material such as natural stone. The wall panel 10 is formed in an irregular shape, for example, the front surface 10a, side surfaces 10c, 10d, 10e, and 10f are formed in an uneven manner. The back surface 10b has an uneven surface 101 formed in the center of the back surface 10b and a flat surface 102 formed by cutting or other processing on the outer edge of the back surface 10b. The mounting bracket 1 is attached to the flat surface 102.

[0083] According to this embodiment, the guide plate portion 22 has an opposing portion 23 that faces the back surface 10b of the wall panel 10, and a back projection portion 24 that extends from the opposing portion 23 so as to extend beyond the side surface of the wall panel 10 and to contact the back surface 10b of other wall panels 10 adjacent to the wall panel. As a result, when the wall panels 10 are stacked vertically, the upper wall panel 10 tends to tilt towards the front surface 10a, but this movement is prevented by the guide plate portion 22, where the back projection portion 24 contacts the back surfaces 10b of each other, the tilt of the upper and lower wall panels 10 is adjusted, and the relative positions in the thickness direction are temporarily fixed by the guide plate portion 22 when they are stacked.

[0084] Furthermore, while stone walls with a slope typically require highly skilled construction techniques, this embodiment allows for the construction of wall structures with a slope while adjusting the slope of the wall panels 10, as the back projections 24 come into contact with the back surfaces 10b of adjacent wall panels 10. Therefore, even without specialized knowledge, wall structures 100 with a slope can be easily constructed.

[0085] <Ninth Embodiment> Next, a wall panel 10 having a mounting bracket 1 in the ninth embodiment will be described. As shown in Figures 20(a) and 20(b), the wall panel 10 is made of stone material such as natural stone. The wall panel 10 is formed in an irregular shape, for example, the front surface 10a, side surfaces 10c, 10d, 10e, and 10f are formed in an uneven manner. The back surface 10b has an uneven surface 101 formed in the center of the back surface 10b, and a flat surface 102 formed by cutting or other processing at the upper and lower edges of the back surface 10b. The mounting bracket 1 is attached to the flat surface 102.

[0086] <Tenth Embodiment> Next, a wall panel 10 having a mounting bracket 1 in the tenth embodiment will be described. As shown in Figure 21, the mounting bracket 1 has a bolt 3 that penetrates the wall panel 10 and a nut 39 that is screwed onto the bolt 3. In this case, it is easy to attach and detach the bolt 3 from the wall panel 10. Therefore, it is easy to replace the wall panel 10.

These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
