a spiral staircase

Abstract

The invention discloses a rotating staircase, comprising: a staircase body; a first support beam; a first embedded part, a third embedded part and a second embedded part are embedded on the first support beam; the first support part, set on the side close to the first embedded part; the second support part, set on the side close to the second embedded part; the third support part, set on the third embedded part; the first locking component, with In order to lock and fix the first support beam, the first embedded part, the second embedded part, the first support and the second support; the second locking component, the second support, the first support beam, the second support The three rigid embedded parts and the third support part are locked and fixed; the first embedded part is fixedly connected to the stair body, the third support part abuts on the back of the first embedded part, and the bottom of the top of the stair body is built on the first support on the piece. The invention solves the problems of the rotating staircase in the prior art that displacement and sliding are easy to cause deformation, cracking and instability of the entire staircase.

Description

technical field [0001] The invention belongs to the technical field of building decoration, and particularly relates to an improvement of a rotating staircase structure. Background technique [0002] The shared public space of large public buildings is large, and there are many floors shared between the upper and lower floors. In order to facilitate the transportation of the upper and lower floors, steel structure stairs are often used to solve the traffic problem of the upper and lower floors. [0003] The steel structure staircase itself is light in weight, simple in shape, short in construction period, material saving, sturdy and durable, and is an ideal staircase structure for this space. [0004] However, in the form of steel structure stairs, it is necessary to solve the connection problem between the steel structure and the concrete beams of the original building. The upper and lower ends of the existing steel structure stairs are welded and fixed by embedded steel p...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the problem that the spiral staircase in the prior art is prone to displacement and sliding, which causes deformation, cracking and instability of the entire staircase. The present invention proposes a new spiral staircase structure. The pre-embedded components and support components are set on the beam, and the spiral staircase can be firmly locked and positioned between the spiral staircase and the first support beam through the cooperation of the first locking component and the second locking component, effectively avoiding the spiral staircase. Displacement, sliding, and cracking and instability of stair sections occur
