[the third embodiment]

10 to 13 show a third embodiment of the present invention. This embodiment exemplifies the structure of the outer wall, which is erected and installed between the beam 2 on the lower floor side and the beam 2 (or small beam) on the upper floor side in a two- to three-story steel frame structure building. The outer wall panel 1 is long and rectangular when viewed from the front, and a plurality of these outer wall panels 1 are connected in the transverse direction, thereby forming the outer wall of the building. However, in this third embodiment, the outer wall panel 1 adopts a curtain wall structure that shakes as the structure shakes.

In the third embodiment, H-shaped steel is used for main columns 3 or other vertical members and beams 2 or other horizontal members constituting the structure. A plurality of bolt holes 201 are formed at predetermined intervals on the inner and outer sides of the upper and lower flanges 21 , 22 of the beam 2 , and an attachment 7 described later is fixed by these bolt holes 201 .

The outer wall panel 1 of the present embodiment adopts a panel material such as an autoclaved lightweight aerated concrete panel or other inorganic materials. As shown in FIG. 10 , on the inner surface of the outer wall plate 1 , a frame body 8 made of shaped steel is installed along the periphery of the outer wall plate 1 . The frame body 8 is composed of a pair of left and right vertical frame members 81, an upper frame member 82 connecting the upper ends of these vertical frame members 81 to each other, a lower frame member 83 similarly connecting the lower ends of these vertical frame members 81 to each other, The middle rail 84 of the middle part of the vertical frame material 81 is comprised.

The left and right longitudinal frame materials 81, the upper frame material 82 and the middle crosspiece 84 adopt thin-walled channel steel with edges. The vertical frame material 81 is arranged in a state of being grooved on the inside of the surface, and the upper frame material 82 and the middle rail 84 are arranged in a state of being grooved downward. The lower frame material 83 adopts the thin-walled edged Z-shaped steel (edge-shaped B-shaped steel) shown in FIGS. 11-12 . The lower frame material 83 is arranged in such a way that the middle part 831 corresponding to the edged Z-shaped steel web is horizontal, and the hanging piece 832 extending downward from the outer side edge of the middle part 831 is in contact with the inner surface of the outer wall panel 1. , The flange portion 833 protrudes from the lower end edge portion of the hanging piece 832 toward the interior of the house. The above-mentioned frame materials are joined to each other by welding, and at the same time, they are fixed on the inner surface of the outer wall panel 1 by using adhesives and small screws.

The outer wall 1 is mounted on the beam 2 by means of mounting fittings 7 . The mounting fitting 7 includes a horizontally arranged shorter beam support plate 71, a vibration-proof plate 72 erected from the middle part of the upper surface of the beam supporting plate 71, and the mounting fitting 7 is in the shape of an inverted T (T) when viewed from the side. . In this anti-vibration plate 72, a vertically long U-shaped hole 73 opened at the upper edge thereof is formed. Bolt holes are respectively formed in approximately half of the exterior side and approximately half of the interior of the girder plate 71 divided by the anti-vibration plate 72 . In the exemplary embodiment, the bolt holes 75 formed in approximately half of the inner side of the girder plate 71 are elongated holes extending in the direction of the interior and exterior of the house. The attachment fittings 7 are arranged at appropriate intervals so that approximately half of the inner side of the beam support plate 71 overlaps the upper surface of the upper flange 21 of the beam 2 , and are fixed to the upper flange 21 of the beam 2 with bolts and nuts 202 . .

On the other hand, in the horizontal portion 821 corresponding to the web of the upper frame member 82 attached to the inner surface of the outer wall panel 1 , bolt holes are formed corresponding to the positions of the attachment fittings 7 . The suspension bolts 84 are inserted into the bolt holes from below, and are fixed by tightening the nuts 85 from the upper side of the horizontal portion 821 with their front ends protruding upward. The front ends of the suspension bolts 84 are inserted into bolt holes formed in approximately half of the outside of the girder plate 71 from below, and the suspension nuts 86 are screwed to the front ends. As a result, the outer wall panel 1 is held in a state where its upper portion is suspended from the attachment fitting 7 .

In addition, on the lower frame member 83 attached to the inner surface of the outer wall panel 1, there is provided a rising piece 834 rising upward from the edge portion of the house inside the middle portion 831 corresponding to the web, and on the rising piece 834, Bolt holes are also formed to match the positions of the mounting fittings 7 . Vibration-proof bolts 87 are inserted into the bolt holes from the outside of the house. The front end of the anti-vibration bolt 87 is inserted into the U-shaped hole 73 of the anti-vibration plate 72 of the mounting bracket 7, and the nut 88 is tightened from the interior side to fix it. However, the anti-vibration bolt 87 can move slightly in the vertical direction along the U-shaped hole 73 of the anti-vibration plate 72 .

As shown in FIG. 10 , when building the outer wall panel 1 , the hanging bolts 84 are inserted into the upper frame material 82 of the outer wall panel 1 and fixed with nuts 85 . In addition, the installation accessories 7 are also installed on the hanging bolts 84 and utilize suspension nut 86 for temporary fixation. In this state, the outer wall panel 1 is lifted by a crane or the like, the mounting bracket 7 is placed on the upper flange 21 of the beam 2 on the upper side, and the beam supporting plate 71 of the mounting bracket 7 is fixed to the upper flange 21 of the beam 2 superior. At this time, if the bolt hole 75 formed in the substantially half of the inner side of the girder plate 71 is a long hole, the protruding dimension of the girder plate 71 relative to the beam 2 can be adjusted within the range of its length.

In addition, the height of the outer wall panel 1 relative to the beam 2 can be adjusted by rotating the hanging nut 86 screwed to the tip of the hanging bolt 84 in the state where the outer wall panel 1 is erected. At this time, a circular clearance fit hole 835 is formed in the lower frame member 83 of the upper adjacent outer wall panel 1 , and the clearance fit hole 835 matches the extended position of the hanging bolt 84 of the lower adjacent outer wall panel 1 . The loose fit hole 835 has an inner diameter larger than the outer diameter of the hanger nut 86 , and an appropriate tool can be inserted inside to rotate the hanger nut 86 from above.

According to this outer wall structure, the outer wall panel 1 is suspended from the backing plate 71 by the hanging bolt 84 , so the outer wall panel 1 can move up and down relative to the backing plate 71 within the range of the axial length of the hanging bolt 84 . In addition, the anti-vibration bolt 87 can also move up and down along the U-shaped hole 73 of the anti-vibration plate 72 . Therefore, as shown in FIG. 13 , during an earthquake, even if the structure 20 of the building shakes laterally, the outer wall panel 1 will not resist the shaking of the structure 20. 7 Rotate while moving up and down. Such a locking action can prevent the outer wall panel 1 from falling off and being damaged.

In addition, at this time, when the suspension bolt 84 is moved upward, the suspension bolt 84 interferes with the lower frame material 83 of the outer wall panel 1 adjacent above, and the lower frame material 83 is formed with the clearance fit hole 835 as described above. Thus, the suspension bolts 84 of the lower outer wall panel 1 can freely move up and down in the clearance fit holes 835 . By taking such considerations, it is possible to ensure a large swing range of the locking action.

Industrial Applicability

The utility model can be used as the outer wall structure of small and medium-sized steel frame structure buildings represented by houses.
