Description
Technical Field
The utility model relates to a building technical field indicates a steel construction stair especially.
Background
The stairs are used for communication among floors and when the height difference is large, the stairs become vertical communication connection tools for duplex type, split level and villas in modern houses and multiple floors, and the design of the stairs is concerned by people more and more deeply.
Traditional stair generally adopt reinforced concrete stair, but reinforced concrete stair have had many drawbacks all the time, mainly have:
1. the stairwell adopts the cast-in-place concrete stairwell, so that great horizontal rigidity is generated, and great influence is caused on the overall calculation of the structure;
2. in order to reduce the influence of the cast-in-place stairs on the whole structure, the sliding support is adopted in the design of the construction drawing, the method really reduces the influence of the cast-in-place stairs on the whole structure, but the complicated multi-stair is difficult to completely design the sliding support, so that the stair structure is difficult to separate from the whole structure, and the whole structure is seriously influenced
Calculating a result of the structure;
3. the construction unit is difficult to be used in the construction process. The bench concrete is difficult to pour, and only manual pouring is needed, so that the construction quality and safety are affected;
4. the reinforced concrete stair has long construction period, more materials and high cost.
