Structural beam hidden suspended-type open rotating staircase structure and construction method thereof

Abstract

The invention discloses a structural beam hidden suspended-type open rotating staircase structure and a construction method thereof. The structural beam hidden suspended-type open rotating staircase structure comprises a staircase which is led to a second-layer floor from a first-layer floor, is poured by water concrete and is of an open rotating structure; the ground of the first-layer floor andthe lower face of the outer rotating side of the staircase are connected through an arc-shaped lower side wall, and the upper face of the outer rotating side of the staircase is connected with an arc-shaped upper side wall; the inner rotating side of the staircase is arranged in a suspended mode; the staircase is supported by a hidden structural beam hidden in the staircase; and the upper and lower side walls poured by water concrete are each of a cavity wall structure. The staircase structure is supported by the hidden structural beam, one side of the staircase is connected with the side walls, the other side of the staircase is suspended, and the staircase structure is concise and practical and in an open rotating form.

Description

technical field [0001] The invention relates to a cantilevered open spiral staircase structure with hidden structural beams and a construction method of the staircase structure, belonging to the technical field of staircase construction. Background technique [0002] At present, the spiral staircases on the market mainly include wooden spiral stairs, steel-wood spiral stairs, steel structure spiral stairs, concrete spiral stairs, etc. Among them, the structure of wooden and steel-wood spiral stairs is relatively simple, and the construction is simple, but the load-bearing capacity is weak. It is generally used in residential and other application fields, and the application is limited; the steel structure spiral staircase has a large arc and a small radius, and the construction is completed by segmented assembly. The construction technology is not difficult, but the steel structure spiral staircase is welded with light steel plates. People usually make noise when walking on ...

Problems solved by technology

[0002] At present, the spiral staircases on the market mainly include wooden spiral stairs, steel-wood spiral stairs, steel structure spiral stairs, concrete spiral stairs, etc. Among them, the structure of wooden and steel-wood spiral stairs is relatively simple, and the construction is simple, but the load-bearing capacity is weak. It is generally used in residential and other application fields, and the application is limited; the steel structure spiral staircase has a large arc and a small radius, and the construction is completed by segmented assembly. The construction technology is not difficult, but the steel structure spiral staircase is welded with light steel plates. People usually make noise when walking on the stairs, and in order to prevent the steel plate from rusting, regular maintenance is required; the concrete spiral staircase is mainly in the form of cast-in-place concrete, which has a wide range of applications, but the structure of the concrete spiral staircase is complex and difficult to construct. The construction technology requirements are high, and more load-bearing beams are needed for support. The exposed load-bearing beams greatly affect the appearance of the stairs.
