[0002] In recent years, steel structure buildings are more and more, whether it is residential engineering or large public building, factory and other buildings, the convenience and speed of steel structure are fully played, but the tiling method of steel structure stair also has big problem, because two different materials, mortar and steel structure can not be effectively combined, often occur ceramic tile hollowing, falling and other problems, seriously affect the use safety.

[0003] The traditional steel structure stair step tiling usually adopts the method of welding steel wire mesh, combines the mortar with the steel structure step, and increases the tension. But the steel wire mesh used is easy to melt when welding, and cannot play the role of binding. Too thick steel wire mesh has poor bending property when used, which brings inconvenience to construction, increases the construction difficulty, and the steel wire mesh is easy to have excessive thickness when bent improperly, which causes the problem that the steel wire mesh exceeds the ceramic tile surface layer, affecting the ceramic tile paving. Frequent welding also increases the safety hazard of the steel structure stair, and the quality of welding is difficult to guarantee, which greatly affects the quality and safety of the stair. Once a disaster such as earthquake occurs, the position of improper or unqualified welding is easy to fall off, which cannot play the role of binding the mortar and the steel stair, causing the ceramic tile to be hollow and fall off. The welding construction involves many safety fireproofing and electrical problems, needs professional welder operation, has high technical requirements for workers, has fire hazard in the construction process, and the whole process is relatively complicated and complex. There is also a way of pouring concrete to increase the rigidity of the steel stair, but the self weight of the concrete is often large, which increases the load of the steel structure when increasing the rigidity of the stair, and is more likely to occur deflection, which causes the ceramic tile to be hollow, and loses and gains.
