Sliding hinged support for prefabricated stair and construction method of sliding hinged support
The invention discloses a siding hinged support for a prefabricated stair and a construction method of the sliding hinged support. The sliding hinged support comprises a bolt pre-buried in a ladder beam raised lug and a long-strip-shaped hole formed in a prefabricated stair plate, the lower end of the pre-fabricated stair plate is connected to the ladder beam raised lug in an overlapped mode, the long-strip-shaped hole is formed in the portion, corresponding to the bolt, of the end of the pre-fabricated stair plate, the direction of the long side of the long-strip-shaped hole is consistent with the length direction of the pre-fabricated stair plate, shoulder steps are arranged on the inner walls of the two sides of the long-strip-shaped hole in the length direction of the long-strip-shaped hole, the pre-buried depth of the bolt meets the requirement of regulated anchoring length, the head of the bolt faces downwards, a first anchoring plate is arranged on the head of the bolt in a penetrating mode, a second anchoring plate is arranged at the free end of the bolt, the second anchoring plate is clamped in the shoulder steps in the long-strip-shaped hole and fixed through nuts, and the interior of the long-strip-shaped hole is covered with a groove type high-strength cover plate so that a sliding cavity of the bolt can be formed. Compared with the prior art, the sliding hinged support has the advantages that the upper portion and the lower portion of the prefabricated stair plate are vertically restrained, the upward vertical displacement of the prefabricated stair plate is limited, and meanwhile the prefabricated stair plate can horizontally slide.
