However, for some industrial plants with special requirements, the steel structure floor slab has more defects. Such as pharmaceutical factories, which have cleanliness requirements for the ground, and therefore, it is usually considered to lay an epoxy mortar surface course. However, the epoxy mortar is thin, and cannot form good adhesion with a steel plate, so that the epoxy mortar surface layer is easy to fall off and damage; meanwhile, due to the fact that the rigidity of the steel plate is not enough, when personnel move and equipment or a material trolley moves, the epoxy mortar surface layer is prone to cracking and falling off. Therefore, the floor slab of the steel structure paved with the epoxy mortar surface layer can not meet the special requirements of production or working environment. Although some modular plants adopt a concrete floor slab formed by in-situ concrete pouring to solve the problems, the maintenance period is long after the concrete is poured, and other installation works in the building process need to be carried out until the concrete reaches a certain strength, so that the construction efficiency is reduced.
