Supporting sliding hinged support structure for prefabricated stair board

Abstract

The utility model discloses a supporting sliding hinge support structure for a prefabricated stair board. The supporting sliding hinge support structure comprises a stair board body. A placing cavity is formed in the stair plate main body; a connecting bolt is arranged in the placing cavity; one end of the connecting bolt extends into the bottom of the placing cavity and extends downwards, and the other end of the connecting bolt is fixed in the placing cavity through a fastening nut; a cement mortar leveling layer is also arranged between the downward extending end of the connecting bolt and the stair board main body; a felt layer is arranged above the cement mortar leveling layer; the upper part of the PE rod is filled and leveled up by injecting glue; hoisting of a tower crane is achieved by arranging the containing cavity in the stair board body and the matched connecting bolts, meanwhile, the stair board body is subjected to a series of arrangement to meet the building requirement of building stairs, the purpose of rapidly building the stairs is achieved, meanwhile, the building difficulty is greatly reduced through the prefabricated stair boards, and the construction cost is reduced. And the construction speed is increased, the construction period is better shortened, and the construction efficiency is greatly improved.
