バー材支持強度が劣化したりするおそれがある。 In general, an expansion joint is constructed by attaching a metal support member to the ends of building frames facing each other with a gap in between, and attaching a cover material to the support member.The cover material closes the gap between the opposing building frames. Although it is covered, the building frame facing it vibrates,
Since their relative positions change due to uneven settlement, etc., the cover material is also configured to respond to this displacement. However, when the opposing frame is suddenly displaced, a considerably large force is applied to the cover material, and the external force at that time is also applied to the support member and the building frame to which the support member is attached. Therefore,
The building frame itself also requires considerable strength.
In contrast, recently, structural materials such as ALC frames, which are lightweight, have good insulation properties, and are easy to process, are increasingly being used for the wall frames of buildings facing each other. Although this type of structural material has the above-mentioned advantages, it also has the disadvantage of being somewhat inferior in strength. Therefore, when constructing an expansion joint, it is necessary to bolt the supporting member directly to the end of the structural material to strengthen it. When fastened and fixed, the stress from the external force applied when the frame changes as described above will be concentrated on the fixed parts, which may cause damage to the building frame or deterioration of the support strength of the cover material. .

した位置の内外面に螺着したものである。 As explained in detail above, the expansion joint according to the present invention extends along the longitudinal direction of the inner and outer surfaces of at least one end of lightweight aerated concrete building frames that face each other with a gap between them. A cover material covering the gap between the building blocks is mounted on the reinforcing support members, and the reinforcing support members are held between one of the pair of L-shaped members. It is formed by overlapping and connecting at the end face on the gap side of the end of the building frame, and the other of each of the L-shaped members is screwed to the inner and outer surfaces of the building frame at a position spaced apart from the end face of the one building frame. This is what I did.

る。 Further, since the pair of L-shaped members are connected by overlapping at the end faces on the gap side of the ends of the building frame, it is possible to correspond to the thickness of the building frame by changing the degree of mutual overlap. moreover,
Each of the above L-shaped members is screwed onto the inner and outer surfaces of the building frame at positions spaced apart from the end faces of the building frame, so they can strongly support the cover material and also prevent stress from concentrating when the frame changes. The durability of the expansion joint can be improved. Furthermore, the work of attaching the reinforcing support member is also easy because it does not require troublesome work such as welding.
