Background
The assembled building is formed by transferring a large amount of field operation work in the traditional building mode to a factory, processing and manufacturing building components and accessories (such as floors, wallboards, stairs, balconies and the like) in the factory, transporting to a building construction site, and assembling and installing on site in a reliable connection mode; with the development of the building industry, the assembled building is widely applied.
Compared with the traditional cast-in-situ stairway, the assembled stairway has the advantages of high installation efficiency, high construction speed and good finished product quality, and is beneficial to shortening the construction period and reducing the environmental pollution and the resource waste.
However, the current fabricated stairway has the following problems: the effective width of the stairway is the horizontal net size between the floor beams at two sides, when the floor beam width is larger than the thickness of the side filling wall, and the filling wall cannot be flush with the inner side surface of the floor beam, the horizontal net size between the filling wall is larger than the effective width of the stairway, so that a larger gap is reserved between the side surface of the ladder plate and the filling wall (for example, when the floor beam width is 300mm and the thickness of the filling wall is 200mm, the gap is 100 mm), objects can fall from the gap to influence the safety of the stairway, and people feel unsafe when seeing the gap at the side surface to influence the comfort of the stairway; at this time, if the traditional cast-in-situ stair is adopted, the local width of the stair plates is directly extended to the inner side of the filling wall to seal the gap, but the prefabricated stair plates are irregular and nonuniform (the positions are wide and narrow), so that the prefabricated stair plates are inconvenient to produce and construct, especially the lifting difficulty is increased (the stair plates cannot be lifted from top to bottom directly and need to be horizontally moved) under the condition that floor beams are arranged on the side surfaces of the high-end flat plates, and the special-shaped stair plates are not beneficial to product standardization for the assembled stair plates, so that the design and production cost is increased, and the production efficiency of the prefabricated members is reduced.
