A prefabricated staircase for building construction and its installation method

Abstract

The invention relates to a prefabricated staircase for building construction and an installation method thereof, comprising a positioning seat located on an upper floor and a supporting seat located on a lower floor, a plurality of step monomers are arranged between the positioning seat and the support seat, and the step monomers are similar to rectangles. There is a height difference between the upper end surfaces of the adjacent step monomers, and there are obliquely arranged main ribs passing through the plurality of ladder monomers, and the two ends of the main ribs are respectively fixed with the positioning seat and the support seat. By adopting the above-mentioned technical scheme, the prefabricated staircase can adjust the number of stair steps, adapt to the installation requirements of the staircase with a certain length range, and reduce the design cost of staircases in different buildings and floors. Moreover, the steps can be prefabricated in batches, and the cost is low. The construction site can be assembled according to the required length of the stairs, and the adaptability is strong.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated staircase for building construction 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 first design the building structure drawing according to the size of the stair bay, and then split the building structure drawing, so as to cast the prefabricated stairs suitable for the building. [0004] The above-mentioned existing technical sol...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: 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 , 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
