[0002] In the field of civil engineering, the traditional site pouring concrete structure needs a large number of formwork supports, and the construction process is complex, the construction period is long, and quality control is difficult. Assembly type structure has become one of the development trends of structural engineering due to its advantages of efficient construction, easy quality control and resource saving.

[0003] The existing laminated slab structure usually adopts chord and web to form a steel bar truss, and pours a concrete slab below the steel bar truss to form a steel bar truss laminated slab structure. Compared with the traditional site pouring concrete structure, although the steel bar truss laminated slab structure is convenient for assembly type manufacturing and construction, the convenience of manufacturing and construction still needs to be improved, the interface shear resistance and anti-lifting performance between the laminated slab and the upper post-cast concrete slab still need to be improved, and the integrity of the structure is still insufficient.

[0011] Preferably, the bending shape of the lower bending part and the upper bending part of each W-shaped web reinforcement comprises one or more of an arc shape, an acute angle, a right angle and an obtuse angle bending.

[0012] Preferably, the materials of the upper main reinforcement, the lower main reinforcement, the distribution reinforcement and the W-shaped web reinforcement comprise one or more of a steel bar, a fiber bar, a steel strand, a steel wire, a composite material bar, a polymer bar and a bamboo bar.

[0013] Preferably, the upper main reinforcement, the lower main reinforcement, the distribution reinforcement and the W-shaped web reinforcement are connected by welding or binding at the intersection.

[0014] Preferably, the materials of the bottom plate comprise one or more of a high-strength concrete material, a high-performance concrete material, a fiber concrete material, an ultra-high-performance concrete material, a polymer concrete material and a common concrete material.

[0015] Compared with the prior art, the beneficial effects of the composite structure are as follows:

[0016] In the utility model, the W-shaped web reinforcement is very easy to manufacture, and the manufacturing efficiency is higher and the manufacturing is more convenient than the complex steel truss in the existing steel truss composite slab structure.

[0018] In the utility model, the modeling, structure and connection between the parts make the shear resistance and the lifting resistance between the parts and the post-cast concrete higher than the existing steel truss composite slab structure. DRAWINGS
