The multi-layered design enhances mold rigidity and produces more uniform molded products. Furthermore, the multiple layers of the double-layer mold, with their corresponding positioning and connections, facilitate easier maintenance. Even if only one layer is damaged, repair costs are relatively low, leading to better economic benefits. Currently, composite slab components are widely used in prefabricated buildings.

This can easily lead to gaps between the two layers, causing grout leakage. This results in low efficiency and poor stability during construction and installation. Therefore, a stable, leak-proof double-layer mold for composite floor slabs is needed. Utility Model Content

[0006] The upper floor slab connecting frame and the lower floor slab connecting frame are both equipped with composite floor slabs, and the surfaces of the upper floor slab connecting frame and the lower floor slab connecting frame are equidistantly threaded with multiple connecting and fixing bolts in a linear array.

[0007] The connecting and fixing bolts are set at the top and bottom of the connecting and fixing steel plate in the same way.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a double-layer mold for leak-proof composite floor slabs, comprising a connecting and fixing steel plate 1, with several floor slab connecting components 2 bolted inside the connecting and fixing steel plate 1. The floor slab connecting components 2 are disposed on both sides of the connecting and fixing steel plate 1, each floor slab connecting component 2 being located between the grooves on both sides of the connecting and fixing steel plate 1. An upper floor slab connecting frame 3 is fixedly connected to the top of the floor slab connecting component 2, and a lower floor slab connecting frame 4 is fixedly connected to the bottom of the floor slab connecting component 2. Composite floor slabs 5 are disposed inside both the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4. Multiple connecting and fixing bolts 6 are equidistantly threaded in a linear array on the surfaces of both the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4, and the connecting and fixing bolts 6 are disposed on the top of the connecting and fixing steel plate 1 in the same manner. At the bottom, the surfaces of the connecting and fixing steel plate 1, the floor slab connecting assembly 2, the upper floor slab connecting frame 3, and the lower floor slab connecting frame 4 are all provided with connecting and fixing screw holes 7 that are compatible with the connecting and fixing bolts 6. The connecting and fixing bolts 6 are threaded into the connecting and fixing screw holes 7 on the floor slab connecting assembly 2 and the connecting and fixing steel plate 1 to fix the connecting and fixing steel plate 1 and the floor slab connecting assembly 2. The upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 are used as fasteners before the composite floor slab 5 is formed, thereby ensuring the formed shape of each composite floor slab 5. At the same time, the presence of the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 can be used to strengthen the compressive strength of the composite floor slab 5 and enhance the stability of the structure. The connecting and fixing steel plate 1, the floor slab connecting assembly 2, the upper floor slab connecting frame 3, and the lower floor slab connecting frame 4 form the overall shell of the double-layer floor slab through a number of connecting and fixing bolts 6.

[0030] Furthermore, the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 are bolted together with a first anti-leakage baffle 17. The surface of the first anti-leakage baffle 17 is provided with connecting fixing screw holes 7 that are compatible with the connecting fixing bolts 6. Multiple polygonal clips 8 are fixedly connected to the surface of the first anti-leakage baffle 17, and each polygonal clip 8 is fixedly connected with a connecting protrusion 9. The upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 are bolted together with a second anti-leakage baffle 18. The surface of the second anti-leakage baffle 18 is provided with connecting fixing screw holes 7 that are compatible with the connecting fixing bolts 6. The surface of the second anti-leakage baffle 18 is provided with connecting slots 11 that are compatible with the polygonal clips 8 and connecting protrusions 9. The connecting fixing steel plate 1 is I-shaped, and both the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 are in contact with the connecting fixing steel plate 1. Both the first anti-grout leakage baffle 17 and the second anti-grout leakage baffle 18 are installed between the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4, and are bolted together by connecting fixing bolts 6. Each connecting fixing bolt 6 is located on one side of the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4, making the structure easier to install and ensuring sealing performance to prevent grout leakage. Polygonal locking blocks 8 and connecting protrusions 9 are installed on the surface of the first anti-grout leakage baffle 17 and are adapted to the connecting slots 11 opened on the second anti-grout leakage baffle 18. Inserting the polygonal locking blocks 8 and connecting protrusions 9 into the corresponding connecting slots 11 ensures the connection stability between the two structures and further enhances the compressive strength. The above structure solves the problem that gaps easily appear between the two floor slabs, causing grout leakage, which leads to low efficiency and poor stability during the building installation process.

[0031] Secondly, the surface of the floor slab connecting component 2 is provided with a receiving groove 10. The first anti-leakage baffle 17 and the second anti-leakage baffle 18 are both located inside the receiving groove 10. The bottom of the upper floor slab connecting frame 3 is fixedly connected to the floor slab heat dissipation layer 12, and the top of the lower floor slab connecting frame 4 is fixedly connected to the floor slab waterproof layer 13.

Rock wool board is specially designed and produced for the exterior walls of buildings and is suitable for dense structures. The composite floor slab 5 is made of sound insulation felt. The sound insulation felt is made of high-density polymer material, which can effectively block sound waves in the air and reduce the propagation of sound. Its high density and good elasticity make sound waves encounter more resistance when passing through the material, thereby reducing the propagation of sound. The sound insulation chamber 14 is filled with sound insulation cotton 15. The sound insulation cotton 15 absorbs the propagating sound, prevents sound diffusion, reduces the propagation of noise, and improves the application range of the device. The floor waterproof layer 13 is a polyurethane coating. The polyurethane coating can form a strong, continuous, and seamless waterproof membrane on the base surface. It has excellent elasticity and extensibility, which can effectively prevent water penetration, protect the building structure from water damage, and improve the waterproof effect.

[0032] Working principle: The connecting bolts 6 are threaded into the connecting bolt holes 7 on the floor slab connecting assembly 2 and the connecting steel plate 1, fixing the connecting steel plate 1 and the floor slab connecting assembly 2. The upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 serve as fasteners before the composite floor slab 5 is formed, thus ensuring the formed shape of each composite floor slab 5. At the same time, the presence of the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4 can strengthen the compressive strength of the composite floor slab 5 and enhance the stability of the structure. The connecting steel plate 1, the floor slab connecting assembly 2, the upper floor slab connecting frame 3, and the lower floor slab connecting frame 4 form a double layer through several connecting bolts 6. The overall shell of the floor slab, the first anti-leakage baffle 17 and the second anti-leakage baffle 18 are both set between the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4, and are bolted together by connecting fixing bolts 6. Each connecting fixing bolt 6 is set on one side of the upper floor slab connecting frame 3 and the lower floor slab connecting frame 4, making the structure easier to install and ensuring sealing performance to prevent grout leakage. The polygonal locking block 8 and the connecting protrusion 9 are set on the surface of the first anti-leakage baffle 17 and are adapted to the connecting slot 11 opened on the second anti-leakage baffle 18. Inserting the polygonal locking block 8 and the connecting protrusion 9 into the corresponding connecting slot 11 ensures the stable connection between the two structures.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
