Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, the keel framework of existing light gauge cold-formed steel shape body of wall is generally light gauge cold-formed steel shape keel column 1 and light gauge cold-formed steel shape upper rail 2, lower guideway 3 are interconnected by tapping screw 4 and form.Light gauge cold-formed steel shape keel column 1 can select single C type cross section column or Two bors d's oeuveres C type cross section column back-to-back according to load level; Keel column 1 spacing is generally 600mm or 400mm.Then at least one deck shingle nail 5 (as shown in Figure 2) is respectively installed in keel framework both sides, the wide * of long * of shingle nail 5 size is thick is generally 3000mm × 1200mm × 12mm or 2440mm × 1220mm × 12mm, the long side direction of shingle nail 5 is consistent with keel stem height direction, the tapping screw 4 recycled lower than 300mm spacing runs through shingle nail and the keel framework component edge of a wing, completes a body of wall.
Namely of the present invention be when damage occurs under horizontal loads for the both sides wallboard of above-mentioned light gauge cold-formed steel shape combined wall, can to its free removal and the rapid reinforcement method of repairing.The method by reinforcing steel covering at original exterior surface of wall supplementary protection, and installs the method for new shingle nail, carries out reinforcement and repair to damaged body of wall.Its concrete steps are as follows:
