One end of the composite panel body 1 has a recess 5, and the other end has a corresponding protrusion 6. The recess 5 is an inwardly recessed step, and the protrusion 6 is an outwardly protruding step. The recess 5 on one end of the composite panel body 1 and the corresponding protrusion 6 on the other end, both being step-shaped, facilitate accurate splicing and positioning between two composite panels, improving splicing precision and stability. Simultaneously, the step-shaped structure increases the contact area at the splicing point, which is beneficial for improving the leak-proof effect.

One end of the reinforcing steel bar 9 is placed inside the composite slab body 1, and the other end extends out of the composite slab body 1 and is inserted into the connection hole 10 at the recess 5 of another composite slab body 1. The reinforcing steel bar 9 is provided on the protrusion 6 side of the composite slab body 1, with one end placed inside the composite slab body 1 and the other end extending out and inserted into the connection hole 10 at the recess 5 of another composite slab body 1. This can enhance the connection strength between the two composite slabs, so that the composite slabs form a tighter whole after splicing, jointly bear the load, and improve the stability and load-bearing capacity of the entire structure.

[0024] A leak-proof component is provided between the composite slab bodies 1. The leak-proof component includes a water-stop strip 7 and a sealant 8. The water-stop strip 7 is placed on the contact surface between the two composite slab bodies 1 and fixed at the recess 5. The sealant 8 is applied to the two ends of the contact surface between the two composite slab bodies 1.

[0025] The waterstop 7 is placed on the contact surface between the two laminated slab bodies 1 and is fixed at the notch 5, and mainly functions to prevent water from penetrating through the joint gap between the laminated slabs, and forms a waterproof barrier by using its waterstop performance. The sealant 8 is coated on the two ends of the contact surface of the two laminated slab bodies 1, further seals the gap between the laminated slabs, prevents water from penetrating from the end gap, cooperates with the waterstop 7, and enhances the overall anti-seepage effect.

The intermediate isolation layer 3 is made of polyethylene foam plastic, is arranged between the prefabricated layer 2 and the post-poured layer 4, plays a role of isolation, can effectively prevent the mutual influence between the prefabricated layer 2 and the post-poured layer 4 due to shrinkage, deformation and other factors, and guarantees the stability of the two in the respective working states. The post-poured layer 4 adopts the concrete layer, is cast in situ, cooperates with the prefabricated layer 2, increases the overall thickness and bearing capacity of the laminated slab, and enables the laminated slab to better bear various loads.
