Description

Rotary stair

Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to a rotary stair.

Background

In order to achieve convenient transportation of the upper and lower floors, and also to beautify space decoration effects, the space is saved, and the space is often solved by a scheme of rotating stairs. But the shared space with larger height at the upper and lower layers is used for rotating stairs, and the number of steps is quite large. The rotating stairway in the prior art is easy to generate displacement and sliding to deform, crack and unstably solve the problem of the whole stairway, and has poor stability and safety.

Disclosure of Invention

In view of the above, it is an object of the present utility model to provide a rotating stair for solving the problems pointed out in the background art.

In order to achieve the above object, the following technical scheme is adopted:

the utility model provides a rotatory stair, includes the stair body, the stair body includes braced frame, braced frame is the heliciform structure, be equipped with a plurality of arc wall portion and a plurality of horizontal installation department on the braced frame, just arc wall portion and horizontal installation department are crisscross to be set up, install the stair footboard on the horizontal installation department, the rail guard is all installed to the both sides of stair footboard, a plurality of vertical support bars of rail guard, a plurality of vertical support bar's upper end is connected with the top guard bar, and the middle part of a plurality of vertical support bars is connected with a plurality of middle part guard bars.

As a further improvement of the utility model, the lower ends of the two protective fences are in a Chinese character 'er' shaped structure, so that the stability of the protective fences can be improved.

As a further development of the utility model, each guard rail is provided with three intermediate guard bars.

As a further improvement of the present utility model, a portion of the lower end of the supporting frame, which contacts the ground, is provided with a horizontal connection portion.

As a further improvement of the utility model, auxiliary wing plates are fixed on both sides of the horizontal connecting part.

As a further improvement of the utility model, the auxiliary wing plate is a triangular plate.

As a further improvement of the utility model, the stair tread is an arc-shaped plate.

The beneficial effects of the utility model are as follows: the utility model has beautiful structure, strong stability and higher safety in use, and solves the problems of easy displacement and sliding of the rotary stair in the prior art, and deformation, cracking and instability of the whole stair.
