A prefabricated spiral staircase installation structure

Abstract

The invention discloses a prefabricated rotating staircase installation structure, belonging to the technical field of architectural decoration, comprising an arc-shaped wall base, a cylindrical base and a plurality of stair mechanisms. The arc-shaped wall base and the cylindrical base are fixedly arranged on On the ground base, the arc-shaped wall base is arranged on the periphery of the cylindrical base, and the axis of the arc-shaped wall base coincides with the axis of the cylindrical base, and a plurality of the stair mechanisms are located in the between the arc-shaped wall base and the cylindrical base; the present invention pre-arranges the arc-shaped wall base and the cylindrical base, and both bases are provided with bosses with the same cross-section, so as to push the stair mechanism to be clamped in the arc. Between the wall base, cylindrical base and ground base, the degree of freedom is fully restricted, the installation and operation are simple and convenient, the construction efficiency is high, and it is easy to disassemble and assemble, which is conducive to the overall maintenance of the spiral staircase, and can realize the two functions of the stair mechanism. secondary utilization, saving resources.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration, and in particular relates to a prefabricated spiral staircase installation structure. Background technique [0002] Spiral staircases, often called spiral or spiral staircases, are usually arranged around a single column. It is popular due to its streamlined shape, elegant and space-saving. [0003] A Chinese patent (CN202021808913.3) discloses a prefabricated concrete spiral staircase. The prefabricated concrete spiral staircase includes: a rest platform, a spiral stair poured central axis column structure and a plurality of stair step structures. The spiral staircase poured central axis column structure includes a middle column structure. Axle-column steel cage, the end of the stair tread structure has a lap joint structure, and a plurality of stair tread structures are lapped upwards step by step through their respective lap joint structures and are sequentially staggered alo...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems of low construction efficiency, inconvenient installation and poor versatility caused by the fact that the spiral staircase is fixed on the base layer of the wall by fasteners when it is installed, and cannot be directly reused after disassembly, resulting in low construction efficiency, inconvenient installation and poor versatility.
