Description

Technical Field

[0001] The utility model belongs to the technical field of floor slabs, and particularly relates to a building floor slab structure with an inter-board waterproof layer. Background Art

[0002] A floor slab is a horizontal load-bearing member used to separate floors in a building. It supports the loads transmitted from the upper floor slab and transfers these loads to the underlying beams, columns, or walls and other load-bearing structures. Currently, reinforced concrete floor slabs are more commonly used, which have high strength, durability, and good fire resistance. The Chinese utility model patent with the publication number CN220928367U discloses a building floor slab structure with an inter-board waterproof layer, which improves the waterproof performance of the floor slab by setting a waterproof layer between the upper and lower floor slabs. However, it still has the problem that the sealing performance between adjacent floor slabs is poor, which is not conducive to waterproofing. Content of the Utility Model

The left floor slab, the middle-section floor slab, and the right floor slab all include an upper plate body and a lower plate body. An intermediate waterproof layer is filled between the upper plate body and the lower plate body. First edge reinforcement plates and second edge reinforcement plates are provided on the left sides of the upper plate bodies and the lower plate bodies of the middle-section floor slab and the right floor slab. First sealing ridges and second sealing ridges are respectively provided at the tops of the first edge reinforcement plates and the second edge reinforcement plates. First mating grooves are provided on the right sides of the upper plate bodies of the left floor slab and the middle-section floor slab. Second mating grooves are provided on the right sides of the lower plate bodies of the left floor slab and the middle-section floor slab.

In combination with the polyurethane waterproof coating layer applied on the surfaces of the upper plate body and the lower plate body and the waterproof expanded perlite filling layer filled between the upper plate body and the lower plate body, the water seepage prevention performance of the floor slab is greatly enhanced. The waterproof expanded perlite filling layer also has the capabilities of sound insulation and heat preservation, effectively reducing the impact of the water flow above the floor slab on the users of the lower layer.
