1. The difference in thickness position
Floor panels are indoors. Most of the floor thickness is 80-160mm. The biggest function of the floor panels is to bear the weight. There are differences in the thickness and the type and density of the steel bars. The roof slab is outdoor, and the thickness of the roof slab is generally 60-80mm, which has great requirements for waterproof, thermal insulation.
2, the difference in function
The main function of the roof panel is to form the enclosure space of the building with the wall and the ground, and play the role of heat preservation, heat insulation, weatherproof, and waterproof. The main function of the floor panel is to vertically separate the space in the building.
3, the difference in structural bearing
From the perspective of structural bearing, roof panels mainly bear the load of slab weight, suspended ceiling, leveling layer, insulation layer, waterproof layer, snow, dust accumulation, and maintenance. The load composition is mostly permanent load. Floor slabs mainly bear loads such as self-weight, plastering, and resident furniture. In addition to the self-weight of the slab, the civil buildings are mainly live loads. Therefore, the proportion of live load in the floor is larger.
