Description

Technical Field

[0001] The utility model relates to a connection structure between prefabricated floor panels and wall panels, belonging to the technical field of assembled buildings. Background Art

[0002] The floor slabs in prefabricated buildings are typically constructed using composite slabs, which are laid on-site. The joints between the upper and lower layers of the composite slabs are sealed using formwork and secondary pouring. This prevents concrete leaks during pouring, but also results in a high volume of concrete filling, necessitating subsequent leveling. After setting, the concrete can crack, leading to further quality issues. Therefore, the connection methods used at the floor slab joints have long been a focus of research for those skilled in the art. Utility Model Content

[0003] The utility model overcomes the shortcomings of the existing technology and provides a connection structure between prefabricated floor slabs / wall panels, which greatly reduces the labor intensity of workers, avoids the risk of cracking, and does not require subsequent grinding and leveling, thereby improving construction efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a connection structure between prefabricated floor slabs / wall panels, comprising a prefabricated floor slab and a steel mesh, wherein the steel mesh is cast in the prefabricated floor slab, and the ends of the prefabricated floor slabs are overlapped on the steel beams, and the ends of the steel mesh extend from the splicing sides between adjacent prefabricated floor slabs to form protruding ends of the steel mesh, and the protruding ends of the steel mesh between adjacent prefabricated floor slabs are staggered and crossed together, and a plurality of interlaced steel bars are horizontally passed through the protruding ends of the steel mesh, and a plurality of bolts are arranged in the gap between the protruding ends of the steel mesh and the interlaced steel bars, and the bolts are welded and fixed to the steel beam, and the splicing seams of the prefabricated floor slabs including the protruding ends of the steel mesh, the interlaced steel bars and the bolts are filled with filling material.

[0005] Furthermore, the number of the interlaced steel bars is either two or four.

[0006] Furthermore, a groove is transversely provided on the end side of the steel beam where the protruding end of the steel mesh is located, and the protruding end of the steel mesh is located in the groove.

[0007] Furthermore, the bolts are arranged in one row or more than one row at the joints of the prefabricated floor slabs.

[0008] Furthermore, the steel mesh is formed by staggering rectangular steel frame units vertically and horizontally, and the end of the steel mesh extending into the groove is a U-shaped closed structure.

[0009] Furthermore, the filling material is concrete.

[0010] Compared with the prior art, the present invention has the following beneficial effects: after the steel mesh is staggered and inserted into the protruding ends of the prefabricated floor slabs, the protruding ends of the steel mesh are penetrated with inserted steel bars, and then fixed together with bolts and filled with concrete, the labor intensity of the workers is greatly reduced, the risk of cracking is avoided, and there is no need for subsequent grinding and leveling, thereby improving construction efficiency.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figures 1 to 6As shown, the utility model is a connection structure between prefabricated floor slabs / wall panels, comprising a prefabricated floor slab 1 and a steel mesh 2. The steel mesh 2 is cast into the prefabricated floor slab 1. The steel mesh 2 is formed by staggering rectangular steel frame units vertically and horizontally. The end of the steel mesh 2 extending into the groove 6 is a U-shaped closed structure. The end of the prefabricated floor slab 1 is overlapped on the steel beam 5. The end of the steel mesh 2 extends from the splicing side between adjacent prefabricated floor slabs 1 to form an extended end of the steel mesh. The end of the steel beam 5 where the extended end of the steel mesh is located is transversely provided with a groove 6, and the extended end of the steel mesh is located in the groove 6. The protruding ends of the steel mesh between adjacent precast floor slabs 1 are staggered and crossed. Multiple interlaced steel bars 3 are inserted transversely through the protruding ends of the steel mesh. The number of interlaced steel bars 3 is two or four. Multiple studs 4 are arranged in the gaps between the protruding ends of the steel mesh and the interlaced steel bars 3. The studs 4 are arranged in one or more rows at the joints of the precast floor slabs 1. The studs 4 are welded to the steel beams 5, and the joints of the precast floor slabs 1, including the protruding ends of the steel mesh, the interlaced steel bars 3, and the studs 4, are filled with concrete. The concrete can be C40 grouting material.

[0021] The utility model realizes that after the steel mesh is staggered and inserted into the protruding ends of the prefabricated floor slabs, the protruding ends of the steel mesh are penetrated with inserted steel bars, and then they are fixed together with bolts and filled with concrete. This greatly reduces the labor intensity of workers and avoids the risk of cracking. There is no need for subsequent grinding and leveling, which improves construction efficiency.

[0022] The connection method of the prefabricated floor slabs in the utility model can be applied to the connection of prefabricated wall panels of the same type and can achieve the same technical effect.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.
