Steel-concrete composite staircase manufacturing method

Abstract

The invention relates to a steel-concrete composite staircase manufacturing method. The steel-concrete composite staircase manufacturing method includes the following process steps that (1) L-shaped tread vertical plates are welded to the inner sides of steel sloped beams; (2) concrete rebars are laid below the steel sloped beams; (3) pedals arelaid on the tread vertical plates, and positioning is conducted by positioning nails; (4) the steel sloped beams on the two sides are used for hanginga lower template used as a template for a cast-in-place rebar concrete ladder section; and (5) concrete is cast, then maintenance is conducted, and finally a steel-concrete compositestaircase is formed. According to the steel-concrete composite staircase manufacturing method,the steel members (steel sloped beams,tread vertical plates) are only used as a part of the template during cast-in-place, stress is not considered, steel-encased does not need to be subjected to fireproof treatment, effect on aesthetics is small, decoration treatment does not need, and it can be used without a decorative treatment, the steel-concrete composite staircase manufacturing method is suitable for a steel structure system, construction is convenient, and assembly is easy.

Description

[0001] 【Technical field】 [0002] The invention relates to a construction method of a staircase, in particular to a production method of a steel-concrete composite staircase, and belongs to the technical field of construction engineering. [0003] 【Background technique】 [0004] In traditional buildings, most of the work needs to be completed on the construction site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction personnel have become barriers to the progress of the construction industry. Stairs, as an important vertical transportation, in the construction process of traditional concrete projects, need to go through formwork, tying steel bars, pouring concrete, and demolishing the formwork. Before the formwork is demolished, it cannot be used for vertical transportation. [0005] With the transformation of traditional buildings into industrialized buildings, under the background of my country's v...

Problems solved by technology

[0006] However, for the stairs in steel structure prefabricated buildings, the steel stair treads are generally made of patterned steel plates, and the bottom of the patterned steel plates needs to be painted with fireproof paint. At the same time, for the appearance of the building, it needs to be decorated and coated, and the post-processing is more troublesome.
