Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing the outer wall structure of the present embodiment. FIG. 2 is a cross-sectional view taken along the line AA of FIG. The outer wall structure of the building of this embodiment is applied to buildings, such as a house and a building, for example. The outer wall structure includes a frame body 2 including columns 5 (shown in FIG. 2) and beams 6, and an outer wall panel 3 fixed to the frame body 2.

  In the frame 2, a vertically extending column 5 and a horizontally extending beam 6 are connected via a joint metal (not shown) or the like. As a result, the frame 2 is formed with a vertical construction space 7 surrounded by the pillars 5 and the beams 6. In FIG.1 and FIG.2, the case where it is the vertical construction space 7 of the 2nd floor or more is shown. The vertical construction space 7 on the second floor or higher is formed by being surrounded by a pair of columns 5 and 5 and a pair of beams 6 and 6, for example. The first floor vertical construction space 7 is formed, for example, by being surrounded by a pair of columns 5 and 5, a beam 6, and a foundation (not shown).

  The column 5 is configured, for example, as a rectangular steel pipe having a rectangular cross section. The beam 6 includes an upper beam 6A disposed above the vertical construction space 7 and a lower beam 6B disposed below the vertical construction space 7. The upper beam 6A and the lower beam 6B are configured as, for example, H-shaped steel, and are a web 6a extending vertically, an upper flange 6b extending horizontally at the upper end of the web 6a, and a lower flange extending horizontally at the lower end of the web 6a. 6c is included.

  FIG. 3 is an exploded perspective view of the exterior panel of the present embodiment. The outer wall panel 3 includes a frame body 11, an exterior plate 12 fixed to the outside of the frame body 11, and an interior base material 13 fixed to the inside of the frame body 11.

  Before the outer wall panel 3 of this embodiment is conveyed to a construction site, the frame 11, the exterior plate 12, and the interior base material 13 are integrally fixed beforehand in a factory or the like. Thereby, it is not necessary to adhere the frame 11, the exterior board 12, and the interior base material 13 in a construction site. Therefore, the outer wall panel 3 is useful for both shortening the construction period of the building and stabilizing the quality.

  The frame 11 includes an upper frame member 11A, a lower frame member 11B, and a pair of vertical frame members 11C and 11C that connect the upper frame member 11A and the lower frame member 11B. Thereby, the frame 11 is formed in the rectangular shape in the front view. The upper frame member 11A, the lower frame member 11B, and the pair of vertical frame members 11C and 11C are configured to include a web 11a and a pair of flanges 11b and 11b fixed to both ends of the web 11a. Thereby, each frame material 11A, 11B, and 11C is formed in the cross-sectional U shape which has the recessed part 11h comprised by the web 11a and a pair of flange 11b, 11b.

  As shown in FIG. 1, the upper frame member 11 </ b> A and the lower frame member 11 </ b> B are arranged so that their respective concave portions 11 h face the inner side in the vertical direction of the frame body 11. As shown in FIG. 2, the pair of vertical frame members 11 </ b> C and 11 </ b> C are arranged such that the respective concave portions 11 h face the inner side in the horizontal direction of the frame body 11. As a result, the space surrounded by the upper frame member 11A, the lower frame member 11B, and the vertical frame members 11C and 11C can be increased, so that a large amount of the heat insulating material 19 can be held.

  The frame 11 is made of metal formed of steel or the like, for example. Moreover, each frame material 11A, 11B, and 11C are joined by welding etc., for example. Such a metal frame 11 has higher rigidity than, for example, a wooden frame. Therefore, the outer wall panel 3 of this embodiment can improve durability.

  As shown in FIG. 1, the length L1a in the vertical direction of the frame 11 of the present embodiment is set to be smaller than the length L2a between the upper beam 6A and the lower beam 6B. Thereby, a gap is formed between the frame 11 and the beam 6. Furthermore, as shown in FIG. 2, the horizontal length L1b of the frame 11 is set to be smaller than the length L2b between a pair of columns 5 and 5 adjacent in the horizontal direction. Thereby, a gap is formed between the frame 11 and the column 5. Therefore, the frame body 11 can be arranged in the vertical construction surface space 7 of the frame body 2.

  As shown in FIGS. 1 and 2, the exterior plate 12 is formed as a foamed concrete panel such as ALC formed in, for example, a rectangular plate shape in front view. The exterior plate 12 of the present embodiment is fixed to the frame body 11 via a trunk edge 18, a moisture permeable waterproof sheet (not shown), and a heat insulating material 19. Thereby, the ventilation layer which can let external air pass between the exterior board 12 and the frame 11 can be formed. Moreover, after the outer wall panel 3 is fixed to the frame 2, for example, an exterior material such as a tile (not shown) may be fixed to the outer surface of the exterior plate 12.

  The interior base material 13 is formed, for example, as a gypsum board formed in a rectangular plate shape when viewed from the front. The interior base material 13 of the present embodiment is fixed to the frame body 11 via a plurality of vertical bars 20A extending vertically, a horizontal bar 20B extending horizontally between the vertical bars 20A, 20A, and a heat insulating material 28. . An air layer is formed between the interior base material 13 and the heat insulating material 28. In addition, a space that can store, for example, an electric cord or the like is formed between the interior base material 13 and the frame body 11. After the outer wall panel 3 is fixed to the frame 2, for example, wallpaper or the like (not shown) may be fixed to the inner surface of the interior base material 13.

  4 is an exploded perspective view of the upper portion of the outer wall structure of FIG. As shown in FIGS. 1 and 4, the outer wall panel 3 has an upper portion of the frame body 11 or a lower portion of the frame body 11, in the present embodiment, an upper portion of the frame body 11 via the first mounting hardware 21. It is fixed to the beam 6A. In addition, the lower part of the frame 11 of this embodiment is being fixed, for example via the anchor bolt 23 which protrudes upwards from the lower beam 6B or the foundation (illustration omitted), as FIG. 1 shows. Furthermore, as shown in FIG. 2, the left and right sides of the frame 11 are fixed to the pillar 5 via the second mounting hardware 22.

  As shown in FIG. 3, at least one first mounting hardware 21 is disposed on the upper frame member 11 </ b> A, and in the present embodiment, a pair is disposed on the upper frame member 11 </ b> A. The pair of first mounting hardware 21 is disposed at both ends of the frame body 11 in the horizontal direction along the outer wall panel 3. Three or more first mounting hardware 21 may be arranged on the upper frame member 11A.

  FIG. 5 is a front view of the first mounting hardware 21. As shown in FIGS. 4 and 5, the first mounting hardware 21 of the present embodiment is arranged at the flat surface portion 21 a, the upper flange portion 21 b disposed at the upper end of the flat surface portion 21 a, and the lower end of the flat surface portion 21 a. The lower flange portion 21c is included. Thereby, the 1st attachment hardware 21 is formed in the U shape which has the recessed part 21h formed of the plane part 21a, the upper flange part 21b, and the lower flange part 21c. As shown in FIG. 4, the horizontal length L3a along the outer wall panel 3 of the upper flange portion 21b of the present embodiment and the horizontal length L3b along the outer wall panel 3 of the lower flange portion 21c are as follows. They are set the same. Moreover, the 1st attachment hardware 21 of this embodiment is formed from metals, such as stainless steel or steel, for example.

  The flat surface portion 21a extends vertically between the upper flange portion 21b and the lower flange portion 21c in a direction orthogonal to the planar direction of the outer wall panel 3. Thereby, the plane portion 21a can receive a horizontal force (hereinafter, simply referred to as “horizontal force”) Ph (shown in FIG. 5) along the outer wall panel 3 from the beam 6.

  As shown in FIG. 5, the thickness W <b> 3 a of the flat surface portion 21 a is set to be smaller than the thickness W <b> 6 of the beam 6. As shown in FIG. 4, the width D <b> 3 of the plane portion 21 a is set smaller than the width D <b> 1 of the frame body 11. Thereby, the rigidity of the flat surface portion 21 a is set to be smaller than the rigidity of the upper flange portion 21 b fixed to the beam 6 and the rigidity of the lower flange portion 21 c fixed to the frame body 11. Accordingly, the flat surface portion 21a is configured as a deforming portion 21T that deforms preferentially over the upper flange portion 21b and the lower flange portion 21c by receiving the horizontal force Ph. The deformation of the deformation portion 21T includes, for example, elastic deformation or plastic deformation.

  As shown in FIG. 5, the upper flange portion 21b of the present embodiment extends horizontally along the lower portion of the beam 6 (that is, the lower surface of the lower flange 6c of the upper beam 6A). The upper flange portion 21b is fixed to the upper beam 6A by a fixing tool 24 such as a bolt 24a and a nut 24b, for example.

  The lower flange portion 21c extends horizontally along the upper portion of the frame body 11 (that is, the upper surface of the web 11a of the upper frame member 11A). The lower flange portion 21c is fixed to the upper frame member 11A by, for example, fixing tools 24 such as bolts 24a and nuts 24b, or fixing means such as welding. The lower flange portion 21c is preferably fixed in advance to the upper frame member 11A, for example, in a factory or the like. Thereby, the installation process of the frame 11 can reduce the 1st attachment hardware 21 in a construction site, and workability can be improved.

  The first mounting hardware 21 can fix the frame body 11 fixed to the lower flange portion 21c and the upper beam 6A fixed to the upper flange portion 21b while being spaced apart from each other in the vertical direction. For this reason, it is possible to prevent the horizontal force Ph (shown in FIG. 5) from being directly transmitted to the frame body 11.

  As described above, the flat surface portion 21a of the first mounting hardware 21 receives the horizontal force Ph (shown in FIG. 5), thereby deforming as a deformation portion 21T that preferentially deforms over the upper flange portion 21b and the lower flange portion 21c. Composed. Due to the deformation of the deformation portion 21T, the horizontal force Ph transmitted from the beam 6 to the frame body 11 is relieved, so that the deformation of the frame body 11 can be prevented. Therefore, the first mounting hardware 21 can improve the durability of the outer wall panel 3.

  The first mounting hardware 21 fixes only the frame 11 among the frame 11, the exterior plate 12 and the interior base material 13 constituting the outer wall panel 3 to the upper beam 6 </ b> A. For this reason, it is possible to prevent the horizontal force Ph (shown in FIG. 5) from being directly transmitted to the exterior plate 12 and the interior base material 13 via the first mounting hardware 21. Therefore, in the outer wall structure of the present embodiment, it is possible to prevent the exterior plate 12, the interior base material 13, the exterior material (not shown) fixed to the exterior plate 12 and the like from being destroyed by the horizontal force Ph. it can. Moreover, since the frame 11 is made of metal having high rigidity, it can be prevented from being deformed by the transmission of the horizontal force Ph. Therefore, the outer wall structure of the present embodiment can improve the durability of the outer wall panel 3.

  As shown in FIG. 3, the first mounting hardware 21 of the present embodiment is arranged one by one at both ends of the flange 11 b of the frame body 11 in the horizontal direction along the outer wall panel 3. For this reason, the pair of first mounting hardware 21 can absorb the horizontal force Ph (shown in FIG. 5) over a wide range in the horizontal direction along the outer wall panel 3 of the frame 11.

  Furthermore, it is desirable that the pair of first mounting hardware 21 and 21 be arranged so that the recesses 21h and 21h (shown in FIG. 5) face each other in the horizontal direction along the outer wall panel 3. Thereby, since each deformation | transformation part 21T and 21T of the 1st attachment hardware 21 is arrange | positioned at the both ends of the horizontal direction along the outer wall panel 3 of the frame 11, the horizontal direction along the outer wall panel 3 of the frame 11 is shown. The horizontal force Ph (shown in FIG. 5) can be absorbed over a wider range. Accordingly, the first mounting hardware 21 can improve the durability of the outer wall panel 3 while preventing the deformation of the frame body 11.

  As shown in FIG. 5, it is desirable that a gap 35 be formed between the upper flange portion 21b of the first mounting bracket 21 and the lower flange 6c of the upper beam 6A. Such a gap 35 receives the horizontal force Ph and causes sliding between the upper flange portion 21b and the upper beam 6A, and partial deformation of the upper flange portion 21b is allowed. Due to the deformation of the upper flange portion 21b, the upper side of the deformation portion 21T (plane portion 21a) is greatly deformed, and the horizontal force Ph (shown in FIG. 5) is effectively absorbed.

  It is desirable that at least a part of the lower flange portion 21c is arranged so as to overlap with a joining region 36 where the upper frame material 11A and the vertical frame material 11C of the frame body 11 are joined. The joining region 36 is a portion having high rigidity in the entire region of the frame body 11. Thereby, since the deformation | transformation part 21T (plane part 21a) becomes low compared with the lower flange part 21c arrange | positioned in the joining area | region 36, it can deform | transform more effectively. Note that the lower flange portion 21 c may be disposed so as to protrude from the joining region 36.

  As shown in FIG. 4, the first mounting hardware 21 of the present embodiment includes a horizontal length L3a along the outer wall panel 3 of the upper flange portion 21b and a horizontal length along the outer wall panel 3 of the lower flange portion 21c. Although the direction length L3b is set to be the same, it is not limited to this. For example, the length L3a of the upper flange portion 21b and the length L3b of the lower flange portion 21c may be different from each other. Thereby, according to the structure of the outer wall panel 3 or the structure of the beam 6, the rigidity of the upper flange part 21b and the rigidity of the lower flange part 21c can be changed suitably.

  Moreover, although the 1st attachment hardware 21 of this embodiment was what was formed in U shape by the plane part 21a, the upper flange part 21b, and the lower flange part 21c, it is not necessarily limited to this. . FIG. 6 is a front view of the first mounting hardware 21 according to another embodiment of the present invention.

  The first mounting hardware 21 of this embodiment includes, for example, a flat surface portion 21a, an upper flange portion 21b extending from the upper end of the flat surface portion 21a to one side in the horizontal direction along the outer wall panel 3, and a horizontal surface from the lower end of the flat surface portion 21a. And a lower flange portion 21c extending to the other side of the direction. Thereby, the 1st attachment hardware 21 is formed in Z character shape (lightning bolt type).

  In such a Z-shaped first mounting hardware 21, similarly to the U-shaped first mounting hardware 21 of the previous embodiment, the deforming portion 21 </ b> T (plane portion 21 a) has a horizontal force Ph (shown in FIG. 5). Since the horizontal force Ph transmitted from the beam 6 to the frame body 11 is relaxed, the deformation of the frame body 11 can be prevented. Furthermore, the Z-shaped first attachment hardware 21 can arrange the upper flange portion 21 b and the lower flange portion 21 c at different positions in the horizontal direction along the outer wall panel 3. Therefore, the first mounting hardware 21 can absorb the horizontal force Ph (shown in FIG. 5) over a wide range in the horizontal direction along the outer wall panel 3.

  FIG. 7 is a front view of the first mounting hardware 21 according to still another embodiment of the present invention. The first mounting hardware 21 of this embodiment includes, for example, the flat surface portion 21a, the upper flange portion 21b extending from the upper end of the flat surface portion 21a to one side in the horizontal direction along the outer wall panel 3, and the lower end of the flat surface portion 21a. And a lower flange portion 21c extending on both sides in the horizontal direction. Thereby, the 1st attachment hardware 21 is formed in the U shape.

  Such a U-shaped first mounting hardware 21 is also deformed by the deformation portion 21T (plane portion 21a) receiving the horizontal force Ph (shown in FIG. 5), and is transmitted from the beam 6 to the frame body 11. Ph is relaxed. In addition, the U-shaped first mounting hardware 21 has lower rigidity of the upper flange portion 21b than that of the lower flange portion 21c. Thereby, when the first mounting hardware 21 receives the horizontal force Ph (shown in FIG. 5), the deformation of the upper flange portion 21b becomes larger than the deformation of the lower flange portion 21c. Due to the deformation of the upper flange portion 21b, the upper side of the deformation portion 21T (plane portion 21a) is greatly deformed, and the horizontal force Ph (shown in FIG. 5) is effectively absorbed.

  Further, the U-shaped first mounting hardware 21 has a lower flange portion 21c having a higher rigidity than the upper flange portion 21b. Thereby, the deformation | transformation of the lower flange part 21c becomes small compared with the deformation | transformation of the upper flange part 21b. Therefore, since the first mounting hardware 21 can hold the frame 11 firmly, it is possible to prevent the frame 11 from being damaged due to the horizontal force Ph (shown in FIG. 5). Durability can be improved.

  FIG. 8 is a front view of the first mounting hardware 21 according to still another embodiment of the present invention. The first mounting hardware 21 of this embodiment includes a base portion 21d extending horizontally, a pair of flat surface portions 21a, 21a extending vertically from both ends of the base portion 21d, and a flange portion extending from the lower end of each flat surface portion 21a, 21a in a flange shape. 21e, 21e. Thereby, the 1st attachment hardware 21 is formed in hat shape. In the present embodiment, the base portion 21d is fixed to the upper beam 6A, and the pair of flange portions 21e and 21e are fixed to the upper portion of the frame body 11 (that is, the upper surface of the web 11a of the upper frame member 11A). In addition, the 1st attachment hardware 21 of this embodiment may be turned upside down, the base 21d may be fixed to the upper part of the frame 11, and a pair of collar parts 21e and 21e may be fixed to the upper beam 6A.

  The base 21d of the present embodiment extends horizontally along the lower part of the beam 6 (that is, the lower surface of the lower flange 6c of the upper beam 6A). The base 21d is fixed to the upper beam 6A by, for example, a fixing tool 24 such as a bolt 24a and a nut 24b. Further, a gap 35 is formed between the base portion 21d and the lower flange 6c of the upper beam 6A. Such a gap 35 receives the horizontal force Ph and causes sliding between the base 21d and the upper beam 6A, and partial deformation of the base 21d is allowed.

  The pair of flat portions 21a and 21a extend vertically up and down perpendicular to the plane direction of the outer wall panel 3 in the same manner as the first mounting hardware 21 of the previous embodiments. The thickness W7a and the width (not shown) of each planar portion 21a of the present embodiment are the same as the thickness W3a (shown in FIG. 5) and the width (shown in FIG. 3) of the planar portion 21a of the previous embodiment. Is set to As a result, the pair of flat portions 21a and 21a receive the horizontal force Ph (shown in FIG. 5), thereby deforming the base portions 21d and the deformed portions 21T and 21T preferentially over the pair of flange portions 21e and 21e. Configured as

  The pair of eaves portions 21e and 21e extend horizontally along the upper portion of the frame body 11 (that is, the upper surface of the web 11a of the upper frame member 11A). The pair of flange portions 21e and 21e are fixed to the upper frame member 11A by, for example, fixing tools 24 such as bolts 24a and nuts 24b, or fixing means such as welding. Further, the pair of flange portions 21e and 21e are fixed to the frame body 11 in the horizontal direction along the outer wall panel 3 (shown in FIG. 3). Thereby, the first mounting hardware 21 is firmly fixed to the frame body 11 over a wide range in the horizontal direction along the outer wall panel 3.

  Such a hat-shaped first mounting hardware 21 is deformed in response to the horizontal force Ph (shown in FIG. 5) because the pair of deformation portions 21T and 21T are deformed, and thus the first mounting hardware 21 provided with only one deformation portion 21T. Compared to 21, the horizontal force Ph transmitted from the beam 6 to the frame 11 is effectively reduced. Therefore, the hat-shaped first mounting hardware 21 can effectively prevent the frame 11 from being deformed. Moreover, since the intensity | strength of the 1st attachment hardware 21 is raised by a pair of deformation | transformation parts 21T and 21T, durability can be improved.

  In the hat-shaped first mounting hardware 21, the base portion 21 d and the pair of flange portions 21 e and 21 e are arranged at different positions in the horizontal direction along the outer wall panel 3. Therefore, the first mounting hardware 21 effectively absorbs the horizontal force Ph (shown in FIG. 5) over a wide range in the horizontal direction along the outer wall panel 3.

  The hat-shaped first mounting hardware 21 has a lower upper rigidity on which the base portion 21d is disposed compared to a lower rigidity on which the pair of flange portions 21e and 21e are disposed. Thereby, when the first mounting hardware 21 receives the horizontal force Ph (shown in FIG. 5), the deformation of the base portion 21d becomes larger than the deformation of the pair of flange portions 21e and 21e. Due to the deformation of the base portion 21d, the upper side of the deformation portion 21T (plane portion 21a) is largely deformed, and the horizontal force Ph (shown in FIG. 5) is effectively absorbed.

  Further, in the hat-shaped first mounting hardware 21, the rigidity of the pair of flange portions 21e and 21e is larger than the rigidity of the base portion 21d. Thereby, a deformation | transformation of a pair of collar parts 21e and 21e becomes small compared with a deformation | transformation of the base part 21d. Therefore, since the first mounting hardware 21 can hold the frame 11 firmly, it is possible to prevent the frame 11 from being damaged due to the horizontal force Ph (shown in FIG. 5). Durability can be improved.

  Although the first attachment hardware 21 of the present embodiment is illustrated as being provided only on the upper frame member 11A, it is not limited thereto. For example, the first mounting hardware 21 may be provided only on the lower frame member 11B, so that only the lower portion of the frame body 11 is fixed to the lower beam 6B.

Accordingly, each guide groove 62 is formed as a vertical groove with its lower part open so that it can be inserted into the horizontal shaft part 25 from above.

  Similar to the second mounting hardware 22 shown in FIG. 13, the second mounting hardware 22 is provided on the frame 11 and the column 5 when the outer wall panel 3 is placed in the vertical construction space 7. From the upper side of the horizontal shaft portion 25, the guide groove 62 provided in the first piece 61a and the second piece 61b is inserted into the shaft portion 25a of each horizontal shaft portion 25. Next, when the holding portion 26 is lowered, the upper end of the guide groove 62 is brought into contact with the shaft portion 25 a of the horizontal shaft portion 25. The guide groove 62 is prevented from coming off from the horizontal shaft portion 25 by the flange portion 25b. Next, the shaft portion 25a of the horizontal shaft portion 25 is finally tightened by a fixing member 27 (shown in FIG. 13). Thus, the left and right sides of the frame body 11 are fixed to the column 5 by the frictional force acting between the horizontal shaft portion 25 and the holding portion 26.

  The second mounting hardware 22 of this embodiment can also prevent the horizontal force Ph (shown in FIG. 5) transmitted from the pillar 5 from being directly transmitted to the frame body 11. The horizontal shaft portion 25 is allowed to move up and down along the guide groove 62 when a horizontal force Ph (shown in FIG. 5) larger than the frictional force between the horizontal shaft portion 25 and the holding portion 26 is applied. Therefore, the durability of the outer wall panel 3 can be improved.

  Furthermore, since the holding part 26 of this embodiment is not fixed to the column 5 or the frame 11 by the fixing tool 31 (shown in FIG. 11) such as a bolt, the horizontal shaft portion 25 is provided in both the column 5 and the frame 11. Vertical movement of the shaft portion 25a along the guide groove 62 is allowed. Therefore, the durability of the outer wall panel 3 can be greatly improved. Moreover, since the 2nd attachment hardware 22 does not need to lift the outer wall panel 3 and insert the guide groove 62 in the horizontal shaft part 25, the workability of an outer wall structure can be improved.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
