Description

Technical Field

[0001] This utility model relates to the field of composite slab technology, specifically a prefabricated composite slab. Background Technology

[0002] Composite slabs, also known as floor slabs or semi-precast slabs, are used in residential and industrial construction. They are mainly used in conjunction with double-skin walls to build monolithic buildings. They are lightweight and have a smaller weight and volume compared to solid precast concrete components, resulting in lower transportation costs when transporting them to the construction site.

[0003] Research revealed that precast composite slabs suffer from poor support strength during use. For example, common composite slabs mainly consist of truss reinforcement made of welded concrete steel bars, visible top chords, two bottom chords filled with concrete, and diagonal connecting rods between the top and bottom chords. The top-poured support structure is simple, which affects the stability of the pouring support.

[0004] There is an urgent need for a prefabricated composite slab to address the technical deficiencies mentioned above. Utility Model Content

The reinforcing block on the top of the waterproof board can improve the stability of the connection. This structure realizes the function of easy waterproofing.

[0017] (3) By setting up hanging rings, support blocks, connecting rods and connecting plates, the support blocks are installed at the four corners of the top of the composite slab base.
