[0022] The best embodiment of the exterior wall panel fixing fixture and the exterior wall panel fixing structure of the present invention will be described below with reference to the drawings. The exterior wall panel fixing structure of the present application is a structure used when installing an exterior wall panel facing the web of a beam material made of H-shaped steel, and is mainly used when a shutter is installed on the outdoor surface of the exterior wall panel. Note that the "through hole", "lip of the horizontal rail material", and "lip of the horizontal frame material" in the present invention correspond to the "second through hole A5", "first lip B2a", and "second lip C1a", respectively, in this embodiment.

[0023] The exterior wall panel fixing structure 1 shown in Figure 1 is a structure for fixing an exterior wall panel B to a beam A made of H-shaped steel, and includes an exterior wall panel fixing bracket 2 for fixing the exterior wall panel B to the beam A, a beam A with the panel surface A1a of the web A1 oriented vertically, an exterior wall panel B formed by fixing a lip channel steel-shaped horizontal rail material B2 that opens toward the interior of the building to the back surface B1a side of the plate-shaped exterior wall finishing material B1, and a lip channel steel-shaped horizontal frame material C1 that is arranged at the bottom of the beam A.

[0024] As shown in Figures 1 and 2, the exterior wall panel fixing bracket 2 comprises a C-shaped first bracket 3 having a first plate portion 31 extending vertically to fix the exterior wall panel B, and a pair of second plate portions 32, 33 extending horizontally from both vertical ends 31a of the first plate portion 31, a second bracket 4 fixing the lower second plate portion 32 to the lower flange A1 of the beam material A, a rod-shaped third bracket 5 penetrating the upper second plate portion 33 in the plate thickness direction and having a tip 5a protruding in the opposite direction to the lower second plate portion 32, and a fourth bracket 6 fixed to the horizontal member C so as to be movable horizontally and fitting into the first lip B2a, which is the lip of the horizontal rail member B2.

[0025] As shown in Figures 2 and 3, the first fitting 3 is a member formed by bending a long and narrow, approximately rectangular metal plate into a C-shape. The first plate portion 31 has an L-shaped locking portion 34 formed on a horizontal edge 31b, which protrudes in the opposite direction to the pair of second plate portions 32, 33, and the lower end portion is bent in a stepped shape. Meanwhile, the lower second plate portion 32 has a first female screw hole 32a formed with a screw thread on the inner peripheral surface. This first female screw hole 32a is formed by penetrating the lower second plate portion 32 from the upper end surface to the lower end surface, performing burring, and then cutting a screw thread on the inner peripheral surface of the hole. The upper second plate portion 33, like the lower second plate portion 32, has a second female threaded hole 33a formed on its inner surface, and this second female threaded hole 33a penetrates the upper second plate portion 33 from the lower end face to the upper end face and is formed by performing a burring process.

[0026] The second fitting 4 is a bolt that is screwed into the first female screw hole 32a, and is installed so as to penetrate the lower second plate portion 32 from the upper end surface to the lower end surface. The third fitting 5 has a first bolt 51 that is screwed into the second female screw hole 33a and penetrates the upper second plate portion 33, and a first nut 52 that is screwed onto the shaft portion 51a of the first bolt 51. The first bolt 51 is installed so as to penetrate the upper second plate portion 33 from the lower end surface to the upper end surface, and the tip 5a protrudes in the opposite direction to the lower second plate portion 32. The second fitting 4 and the first bolt 51 installed in the first fitting 3 in this way can be moved in the axial direction by rotating each of them.

[0027] 2, 4, and 10 has a locking plate 61 that locks onto the second lip C1a which is the lip of the horizontal frame member C1, a fitting plate 62 that is positioned below the locking plate 61 and fits onto the first lip B2a of the horizontal rail member B2, a second bolt 63 whose head 63a is crimped to the locking plate 61 and whose shaft 63b passes through the fitting plate 62, and a second nut 64 that screws onto the shaft 63b of the second bolt 63 protruding from the fitting plate 62. The locking plate 61 is a C-shaped member made up of a slightly elongated first plate piece 61a extending horizontally and a pair of second plate pieces 61b protruding upward from both ends of the first plate piece 61a in the short direction. The first plate piece 61a, which is a substantially rectangular metal plate, has two corners located on one diagonal line cut obliquely, as shown in Fig. 4, and the distance L1 in the short side direction is less than the width W1 between the second lips C1a, and the distance L2 in the long side direction is greater than the width W1 between the second lips C1a and less than the groove width W2 of the horizontal member C1. Two exterior wall panel fixing brackets 2 are installed for one exterior wall panel B.

[0028] The fitting plate 62 is composed of a long and narrow cut plate piece 62a extending in the horizontal direction and having one end edge in the longitudinal direction cut into a trifurcated shape to form three protrusions 620, three rising pieces 62b extending upward from the tips of the protrusions 620, and a pair of extending pieces 62c extending downward from both ends of the short side of the cut plate piece 62a. As shown in the figure, the cut plate piece 62a has an insertion hole 62d penetrating in the plate thickness direction, and the shaft 63b of the second bolt 63 can be inserted into this insertion hole 62d. In addition, the three protrusions 620 are formed so that the protrusions 620 at both ends have approximately the same length from the base end to the tip, and the central protrusion 620 is formed so that the length from the base end to the tip is longer than the protrusions 620 at both ends by the plate thickness of the first lip B2a.

[0029] As shown in Fig. 1 and Fig. 5, the beam material A made of H-shaped steel has through holes A4, A5, and A6 formed in the web A1, the lower flange A2, and the upper flange A3, which penetrate in the plate thickness direction, respectively. The first through hole A4 formed in the web A1 is a wiring hole for the shutter E described later, and is formed to pull the wiring extending from the shutter box E1 into the building. The second metal fitting 4 can be inserted into the first through hole A5 formed in the lower flange A2, and the first bolt 51 can be inserted into the third through hole A6 formed in the upper flange A3. Therefore, the second through hole A5 and the third through hole A6 are formed at the locations where the exterior wall panel fixing metal fittings 2 are installed.

[0030] The exterior wall panel B fixed to the beam A shown in Fig. 6 is an exterior wall material installed above the opening D, and is also installed as a base material for fixing the shutter box E1 as shown in Fig. 1. As shown in Fig. 7, the exterior wall panel B has a flat exterior wall finishing material B1 and a lip channel steel horizontal rail material B2 fixed to the back surface B1a of the exterior wall finishing material B1. The exterior wall finishing material B1 is a plate material made of precast concrete molded to a uniform thickness, and its surface is finished with a decorative finish. On the other hand, two horizontal rail materials B2 are installed with a vertical gap between them, and are embedded in the exterior wall finishing material B1 with an opening on the back surface B1a of the exterior wall finishing material B1. As shown in Figures 1 and 6, the exterior wall finishing material B1 has a fourth through hole B1b formed between the two horizontal rail materials B2, which penetrates in the thickness direction of the plate, and the wiring of the shutter E can be pulled into the first through hole A4 of the beam material A through this fourth through hole B1b.

[0031] The exterior wall finishing material B1 is formed with a width of about 960mm to 980mm and a height of about 230mm to 250mm, and is a long member extending horizontally as shown in the figure. In addition, the two horizontal rail members B2 are arranged so that the distance from the upper and lower ends of the exterior wall finishing material B1 to their respective vertical centers is about 80mm to 85mm or more.

[0032] In the opening D shown in Fig. 1 and Fig. 6, a bay window having a height substantially equal to the ceiling height of the lower floor is installed. The sash frame D1 of the bay window is supported and fixed to the framework C consisting of a horizontal framework C1, a second horizontal framework C2 arranged under the horizontal framework C1, and a pair of vertical members C2 arranged at both horizontal ends of the horizontal framework C1 and the second horizontal framework C2. As shown in Fig. 6, the framework C is installed under the beam A, and the horizontal framework C1 is bolted to the beam A with the second lip C1a facing downward. In addition, as shown in Fig. 10, the horizontal framework C1 has a fifth through hole C1b formed at a position aligned with the second through hole A5, and the shaft portion 41a of the second metal fitting 4 can be inserted into this fifth through hole C1b. The horizontal frame member C1 and the lower flange A2 are spaced apart, with a gap of approximately 10 mm being formed between the upper end surface of the horizontal member C1 and the lower end surface of the lower flange A2.

[0033] As shown in Figures 1 and 6, a lip-channel steel-shaped exterior wall horizontal member C4 for fixing an upper floor exterior wall panel B3 is installed above beam A. Both horizontal ends of this exterior wall horizontal member C4 are bolted to beam A with the lip facing up, but no bolt holes are formed in the part of the lower end surface where the exterior wall panel fixing bracket 2 is installed. Also, a gap of about 10 mm is formed between the lower end surface of the exterior wall horizontal member C4 and the upper end surface of the upper flange A3, but because this gap is small, it is not possible to screw a nut by protruding the first bolt 51 from the third through hole A6 of the upper flange A3.

[0034] Next, the fixing structure 1 of the exterior wall panel will be described. First, as shown in Fig. 8, with the first plate portion 31 of the first fitting 3 facing the outdoor side, the lower second plate portion 32 is inserted into the gap between the lower flange A2 and the horizontal framework C1 to abut against the lower end surface of the lower flange A1. Then, the second fitting 4 is inserted into the second through hole A5 from above the lower flange A2, and while rotating, the shaft portion 41a is screwed into the first female screw hole 32a, and further inserted into the fifth through hole C1b, as shown in Fig. 10. Then, the second fitting 4 is moved downward until the head portion 41b of the second fitting 4 abuts against the lower flange A2, and the lower second plate portion 32 is fixed to the lower flange A2. In the unlikely event that the fifth through hole C1b is not formed in the horizontal member C1, as shown in Figure 13, the third nut 42 can be screwed onto the shaft portion 41a of the second fitting 4 before inserting the second fitting 4 into the second through hole A5, and the third nut 42 can be tightened after the shaft portion 41b has penetrated the lower second plate portion 32, thereby preventing the second fitting 4 from wobbling.

[0035] 8 and 9, the first bolt 51 of the third fitting 5 screwed into the second female threaded hole 33a is rotated and moved toward the upper flange A3, and the tip of the first bolt 51 is inserted into the third through hole A6 of the upper flange A3. Then, the first nut 52 is rotated and moved toward the upper flange A3 and abutted against the upper flange A3, and the first nut 52 is tightened to press the lower end surface A3a of the upper flange A3. In this way, the first bolt 51 is stretched between the lower flange A2 and the upper flange A3, thereby fixing the upper second plate portion 23 to the upper flange A2.

[0036] Next, as shown in Fig. 10, the fourth fitting 6 is fixed to the horizontal truss member C1. First, with the rising piece 62b of the fitting plate 62 facing the outdoor side, the longitudinal direction of the first plate piece 61a is aligned with the longitudinal direction of the horizontal member C1, and the locking plate 61 is inserted into the groove of the horizontal truss member C1. Then, the locking plate 61 is rotated so that the longitudinal direction of the locking plate 61 is perpendicular to the longitudinal direction of the horizontal truss member C1, and the locking plate 61 is locked to the second lip C1a. The second nut 64 is then tightened to bring the fitting plate 62 into contact with the second lip C1a, and the fourth fitting 6 is fixed to the horizontal truss member C1. The fourth fitting 6 can be moved horizontally to any position by loosening the second nut 64.

[0037] Next, as shown in Fig. 11, the exterior wall panel B is brought close to the exterior wall panel fixing metal fitting 2 with the horizontal rail material B1 facing the indoor side, and the first lip B2a of the upper horizontal rail material B2 is hooked onto the locking portion 34 of the first metal fitting 3, while the first lip B2a of the lower horizontal rail material B2 is fitted between the rising pieces 62b at both ends of the fourth metal fitting 6 and the rising piece 62b in the center. Then, a counterbore F1 is formed on the outdoor surface of the exterior wall finishing material B1 with a dedicated tool, and a pilot hole F2 for driving a screw F is opened in the exterior wall base material B1 and the first plate portion 31, and the screw F is driven from the counterbore F1 into the pilot hole F2 to complete the fixing of the exterior wall panel B to the beam material A. Finally, as shown in Fig. 1, the shutter E and the shutter box E1 are fixed to the outdoor surface of the exterior panel B, and the shutter wiring is drawn into the fourth through hole B1b and the first through hole A4 of the beam material A described above.

[0038] In this way, the fixing structure 1 of the exterior wall panel of the present application can fix the exterior wall panel B to the beam A even when the upper flange A3 or the web A1 cannot be fastened with bolts and nuts because another member is placed on top of the beam A or because it is not possible to form a bolt hole in the web A1 of the beam A.

[0039] In this embodiment, the case where the tip of the first bolt 51 is inserted into the third through hole A6 of the upper flange A3 has been described, but the first bolt 51 can be braced below the upper flange A3. For example, when a balcony is formed on the upper floor, a screen panel is installed around the floor of the balcony. In this case, as shown in FIG. 12, a screen horizontal frame member G for supporting and fixing the screen panel may be fixed to the beam A by a third bolt G1 and a fourth nut G2 inserted through the third through hole A6. In this way, when the first bolt 51 cannot be inserted into the third through hole A6, the tip 5a of the first bolt 51 can be pressed against the third bolt G1 to brace the first bolt 51. Even when the third through hole A6 is not formed in the upper flange A3, the first bolt 51 can be braced by pressing the tip 5a of the first bolt 51 and the first nut 52 against the lower end surface A3a of the upper flange A3.

[0040] The embodiment of the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the scope of the concept of the present invention. [Industrial Applicability]
