Description
Technical field
The present invention relates to a kind of concealed open spiral stairs structure of overhanging type of structural beams and the construction parties of the staircase structure
Method belongs to stair technical field of construction.
Background technique
The spiral stairs occurred on the market at present mainly have wooden spiral stairs, steel wood spiral stairs, steel construction rotating floor
Ladder, reinforced concrete spiral stairs etc., in which: wooden and steel wood spiral stairs structure types are simpler, and construction is simple, but load-bearing energy
Power is weak, is generally used for the application fields such as house, using limited；The radian of steel construction spiral stairs is larger, radius is smaller, and construction is adopted
It is completed with segmented assembly, construction difficulty is small, but steel construction spiral stairs are welded using the steel plate of lighter in weight, the building Ren Zou
It would generally make a noise when on ladder, and to prevent steel plate from getting rusty, need periodic maintenance；Reinforced concrete spiral stairs mainly use cast-in-place
Concrete form, application field is wider, but structure is complicated for reinforced concrete spiral stairs, and difficulty of construction is larger, construction technical requirement
Height needs more spandrel girder to support, and exposed spandrel girder largely affects the appearance of stair, prior
It is that there is presently no appearance to connect on one side with side wall, another side overhanging, structural beams are hidden, open type spiral stairs structure.
Summary of the invention
The purpose of the present invention is to provide a kind of open spiral stairs structure of the concealed overhanging type of structural beams and the stair knots
The construction method of structure, the staircase structure are supported using concealed structural beams, and stair are connect with side wall on one side, and another side overhanging is
A kind of staircase structure of the open rotated versions of brief and practical.
To achieve the goals above, the invention adopts the following technical scheme:
The open spiral stairs structure of a kind of concealed overhanging type of structural beams, it is characterised in that: it includes logical from the first floor
Toward the stair of open rotational structure made of the second floor, pouring exposed concrete, the outer rotation of first layer flooring and stair
