A kind of prefabricated staircase of prefabricated building and its installation method

Abstract

The invention relates to a fabricated building prefabricated staircase and a mounting method thereof. The fabricated building prefabricated staircase comprises stair single bodies, the stair single bodies are each in a similar rectangle shape, connecting heads are fixed to one side faces of the stair single bodies in a protruding mode, connecting grooves matched with the connecting heads in shapeare formed in the side faces, away from the connecting heads, of the stair single bodies in a sunken mode, the connecting heads and the connecting grooves are formed in a staggered mode in the heightdirection, and the adjacent stair single bodies are mutually connected through the connecting heads and the connecting grooves in a clamped mode; and a main steel bar column is jointly arranged between all the stair single bodies in a penetrating mode, and auxiliary steel bar columns are arranged between all the adjacent stair single bodies in a penetrating mode. Through arrangement that the stairsingle bodies are spliced to form the prefabricated staircase, the number of staircase steps of the prefabricated staircase can be adjusted, the effect of meeting the mounting demands in the certainlength range is achieved, the design costs of the staircases of different buildings and different floors is reduced, the stair single bodies can adopt the batched prefabricating mode, the cost is low,assembling is conducted on a construction site according to the required staircase length, and the adapting ability is high.

Description

technical field [0001] The technical field to which the present invention relates, in particular, relates to a prefabricated staircase of a prefabricated building and an installation method thereof. Background technique [0002] At present, the prefabricated reinforced concrete stairs refer to the stairs that are assembled and assembled with components produced by prefabricated factories or made on site. Compared with cast-in-place reinforced concrete stairs, the use of prefabricated stairs can improve the level of industrial construction, save formwork, simplify operating procedures, and greatly shorten the construction period. [0003] The existing mold design method for the prefabricated stairs of prefabricated buildings is to design the building structure drawing according to the size of the stair bay, and then split the building structure drawing. During the splitting process, the designers could not coordinate the resources of the relevant industrial chain very well, ...

AI Technical Summary

Problems solved by technology

During the splitting process, the designers cannot coordinate the resources of the relevant industrial chain very well, resulting in the prefabricated stairs after the splitting are often personalized stairs, resulting in a variety of prefabricated stairs and a low degree of standardization of prefabricated stairs

As a result, the designer has a heavy workload, the reuse rate of the prefabricated staircase mold is low, the adaptability is poor, and there are many construction problems on site. Therefore, there is room for improvement
