Prefabricated building structure and construction method

Abstract

The invention discloses a prefabricated building structure and a construction method, and relates to the technical field of prefabricated buildings. The problem that the size of a prefabricated stair is not easy to modify is solved. The prefabricated building structure comprises a stair body installed between a floor body and a middle platform, wherein the stair body comprises a bearing plate and further comprises a plurality of treading pieces installed on a supporting plate; each treading piece comprises a treading plate and the supporting plate perpendicularly connected with the treading plate; the end, away from the treading plate, of the supporting plate abuts against the bearing plate; an inserting groove is formed in the side face, back on to the treading plate, of the supporting plate; and a mounting base is fixedly connected to the upper end of the bearing plate, an inserting groove is also formed in the mounting base, sinking grooves are formed in the floor body and the middle platform correspondingly, and pushing blocks are installed in the sinking grooves and located between the lower end of the bearing plate and the supporting plate. According to the prefabricated building structure and the construction method, the length size of the prefabricated stair can be conveniently changed by people on a construction site, and thus the stair can better adapt to the height between floors.

Description

technical field [0001] The present application relates to the technical field of prefabricated buildings, in particular to a prefabricated and assembled building structure and a construction method. Background technique [0002] With the development and requirements of housing industrialization, prefabricated buildings have been vigorously promoted. As the main vertical traffic of the building and the main channel for emergency evacuation, the prefabricated staircase is one of the main indicators of the assembly rate of the prefabricated building. [0003] The current prefabricated stairs, as described in patent No. CN211341176U, include floor slabs, intermediate platform structures and prefabricated concrete stairs, the floor slabs are arranged in parallel at intervals in the vertical direction; the intermediate platform structure is arranged between two adjacent floor slabs room; the precast concrete staircase includes a plurality of precast concrete staircase unit bodies...
