Technical Field

They are composed of multiple layers of thin plates stacked together, usually made of materials such as wood, concrete or steel, and are stacked through special connection methods.

[0003] The existing publication number CN216340348U discloses a composite plate assembly structure, including a first composite plate and a second composite plate, the upper surface of the first composite plate is connected to a U-shaped positioning cylinder by bolts, the interior of the U-shaped positioning cylinder is inserted with a positioning rod for limiting the second composite plate, the surface of the positioning rod is covered with a return spring, the upper surface of the second composite plate is connected to a fixing plate for limiting the positioning rod by bolts, a fixing hole for limiting is opened at the edge of the upper surface of the first composite plate, a clamping block for limiting is fixedly connected to the edge of the lower surface of the second composite plate, the bottom end of the clamping block is clamped in the inside of the fixing hole, and one side of the upper surfaces of the first composite plate and the second composite plate are fixedly connected to a rubber pad for maintaining sealing.

[0004] The existing composite plate assembly structure still has the following shortcomings:

However, the composite slab is a prefabricated building material, so its rigidity and prestressed bearing capacity will be weak, and when connected to the concrete layer, the connection effect between the two building layers is also weak.

[0006] 2. There is usually a ditch between the adjacent parts of the two composite plates for the purpose of placing the steel bar bundles. The steel bars at the ends of the composite plates also need to be connected to it. The straight-through steel bars have caused the steel bars at one end to be tied loosely. Utility Model Content

The longitudinal auxiliary fixing structures include arc-shaped steel bars 5. The lower ends of the arc-shaped steel bars 5 are fixedly connected to the composite plate 1. The upper ends of the two arc-shaped steel bars 5 are fixed to each other to form a bottom fixing member. The two arc-shaped steel bars 5 form an angle of 50° between them. A plurality of bottom fixing members are arranged in a linear array on the upper surface of the composite plate 1. The upper ends of the bottom fixing members are fixedly connected to the connecting steel bars 6.

[0026] The two sets of transverse auxiliary fixing structures are symmetrical with respect to the central axis of the composite plate 1. The transverse auxiliary fixing structure is arranged on the outside of the longitudinal auxiliary fixing structure. The transverse auxiliary fixing structure includes a connecting plate 7. Two connecting holes 8 are arranged on the side of the connecting plate 7. The connecting holes 8 are arranged above the connecting steel bars 6.

Steel bars can be placed in the connecting holes 8 on the connecting plate 7 in the transverse auxiliary fixing structure.
