[0002] In the field of building construction, prefabricated floor slabs are widely used due to their high construction efficiency and strong industrialization. Currently, prefabricated floor slabs mostly use traditional welding and bolt connections to install load-bearing rods, but these connection structures have obvious defects. Welded connections are easily affected by the construction environment and personnel skills, resulting in poor quality stability, and high-temperature welding may damage the floor slab structure; bolted connections have the risk of loosening after long-term use, leading to a decrease in load-bearing reliability.

[0003] For example, the prefabricated floor slab dowel connection structure proposed in patent CN218521853U, while optimizing the installation method to some extent, still has problems such as insufficient seismic performance under complex working conditions and unverifiable long-term reliability. In addition, existing connection structures are generally complex and time-consuming to install, making it difficult to meet the rapid construction needs of prefabricated buildings.

One end of the movable connecting plate is provided with a symmetrical seventh threaded hole, and the other end of the movable connecting plate is provided with a symmetrical eighth threaded hole.

[0009] According to the prefabricated floor slab force transmission rod connection structure, the lower end of the first floor slab is provided with symmetrical fifth threaded holes, and the fifth threaded holes and the seventh threaded holes are correspondingly and movably connected with first threaded buttons.

[0010] According to the prefabricated floor slab force transmission rod connection structure, the lower end of the second floor slab is provided with a symmetrical sixth threaded hole, and the sixth threaded hole and the eighth threaded hole are correspondingly and movably connected with second threaded buttons.

[0011] According to the prefabricated floor slab force transmission rod connection structure, the lower end of the fixed connection plate is fixedly connected to a plurality of symmetrical connecting columns, and the connecting columns are provided with corresponding positioning grooves, and the movable connection plate is provided with a plurality of positioning shaft holes.

The cooperation between the positioning shaft hole and the connecting column and positioning groove enables precise positioning and installation, reduces construction errors, ensures uniform force transmission between floor slabs, and improves the overall structural load-bearing capacity and reliability.

[0015] 2. The threaded connection simplifies the installation process, eliminating the need for complex welding techniques and reducing construction difficulty and time costs. The fixed nut, combined with the threaded groove, allows for flexible adjustment of the movable connecting plate position to adapt to different working conditions, while also facilitating disassembly and maintenance.
