[0023] Example

[0024] like Figures 1 to 8As shown, a fully assembled prefabricated component connection structure proposed by the present invention includes a building base layer 1 and a prefabricated component plate 2, wherein the upper surface of the building base layer 1 is provided with a plurality of basic steel bars 11, and further includes: a telescopic card slot 21 opened at the bottom of the prefabricated component plate 2, a telescopic card bottom block 3 is slidably provided inside the telescopic card slot 21; an insert block mechanism arranged on the telescopic card bottom block 3 so that the bottom end of the prefabricated component plate 2 is connected to the basic steel bars 11; a limiting mechanism installed on the insert block mechanism for clamping the prefabricated component plate 2 in the downward telescopic card slot 21.

[0025] Furthermore, the insert block mechanism includes a plurality of first circular slots 23 corresponding to the basic steel bars 11 and provided in the telescopic card slot 21, a plurality of installation sockets 31 for the basic steel bars 11 to pass through and correspondingly overlap with the first circular slots 23 are provided on the telescopic card bottom block 3, and a plurality of positioning slots 33 arranged linearly and corresponding to the installation sockets 31 are provided on the outer wall of the telescopic card bottom block 3, and the positioning slots 33 can help construction personnel accurately determine the installation position of the structure or component according to the design drawings and construction requirements, thereby improving the accuracy and construction quality of the entire project. A pair of support plug rods 34 are fixedly connected to the upper surface of the telescopic card bottom block 3, and a pair of second circular slots 24 for the support plug rods 34 to be inserted are also provided inside the telescopic card slot 21. The pair of support plug rods 34 and the second circular slot 24 are symmetrically arranged with the installation slot 32 as the center, and a release mechanism is provided on the prefabricated component plate 2 to allow the telescopic card bottom block 3 to escape from the telescopic card slot 21.

[0026] Among them, the release mechanism includes a sliding groove 36 opened on the telescopic card base block 3, an installation slot 32 is opened inside the sliding groove 36, a bolt groove 25 corresponding to the installation slot 32 is opened on the prefabricated component plate 2, and the internal spiral connection of the bolt groove 25 is inserted into the bolt screw 252 of the installation slot 32.

[0027] Secondly, the limiting and slowing mechanism includes an elliptical slot 22 provided in the telescopic card slot 21, a U-shaped support rod 35 inserted into the elliptical slot 22 is fixedly connected to the upper surface of the telescopic card bottom block 3, an arc-shaped block 351 is provided inside the top of the U-shaped support rod 35, and a U-shaped slide 352 slidably connected to the U-shaped support rod 35 is fixedly connected inside the arc-shaped block 351, and the U-shaped slide 352 does not hinder the U-shaped support rod 35 from sliding in the elliptical slot 22. A pair of buffer springs 353 are provided on the top of the arc-shaped block 351, and the buffer spring 353 is a spring used to absorb and alleviate shock, vibration or pressure changes. It consumes kinetic energy through elastic deformation, reduces the vibration and noise caused by shock or load changes in the mechanical system, and plays a role in protecting the system or components. A pair of buffer springs 353 and the U-shaped slide 352 are symmetrically arranged with the bolt screw 252 as the center, one end of the buffer spring 353 is fixedly connected to the arc-shaped block 351, and the other end of the buffer spring 353 is fixedly connected to the U-shaped support rod 35.

[0028] Furthermore, the bolt groove 25 has a hexagonal recessed bolt head 251 fixedly connected to one end of the bolt screw 252. The bolt screw 252 and the hexagonal recessed bolt head 251 form a hexagonal bolt, which is a bolt with a hexagonal inner hole, and usually needs to be tightened or loosened with a hexagonal wrench (i.e., a hexagonal wrench or an L-shaped wrench). The head of this bolt has a hexagonal inner hole, which can be operated by a hexagonal tool (usually a hexagonal wrench or a hexagonal socket), and has a high torque bearing capacity and operating space. A fixed sleeve is provided with a limit clamp 253 at one end of the bolt screw 252 away from the hexagonal recessed bolt head 251. When the limit clamp 253 moves to abut against the sliding groove 36, the end of the bolt screw 252 is inserted into the installation slot 32. When the limit clamp 253 moves to abut against the inner wall of the telescopic slot 21, the end of the bolt screw 252 is in a state of clamping the arc block 351. One end of the screw bolt 252 that is out of the installation slot 32 is used to clamp the arc-shaped clamping block 351 .

[0029] Furthermore, a pair of inclined tie rods 12 are provided on the building base layer 1 and the prefabricated component plate 2. The inclined tie rods 12 are structural elements used to temporarily support the prefabricated component plate 2 to maintain stability during the construction process. Its main function is to ensure that the prefabricated component plate 2 is in a safe and stable state during installation, construction or transportation, and to prevent tilting, sliding or collapse due to external forces or improper construction. Both ends of the inclined tie rods 12 are provided with rotating seats, and the rotating seats are fixedly connected to the corresponding building base layer 1 and prefabricated component plate 2.

[0030] In this embodiment, when it is necessary to use a fully assembled prefabricated component connection structure, such as Figure 2 As shown, after the prefabricated component plate 2 is lifted by the lifting device, the bottom end of the prefabricated component plate 2 is at a certain height from the upper surface of the building base layer 1. At this time, the hexagonal recessed bolt head 251 can be rotated by a tool, and the rotation of the hexagonal recessed bolt head 251 drives the bolt screw 252 to rotate. Since the bolt screw 252 and the prefabricated component plate 2 are spirally connected, the end of the bolt screw 252 away from the hexagonal recessed bolt head 251 is disengaged from the installation slot 32. At the same time, the bolt screw 252 drives the limiting clamp ring 253 to press against the inner wall of the telescopic slot 21. At this time, the telescopic bottom block 3 moves downward and disengages from the telescopic slot 21 due to the action of gravity, and the telescopic bottom block 3 then slides vertically along the second circular slot 24 through the support rod 34. Then, the U-shaped support rod 35 slides along the elliptical slot 22 until the arc-shaped block 351 on the U-shaped support rod 35 abuts against the end of the bolt screw 252, and the U-shaped slides 352 at both ends of the arc-shaped block 351 slide along the U-shaped support rod 35, and the arc-shaped block 351 and the buffer spring 353 provided in the middle of the U-shaped support rod 35 buffer and reduce shock, so that the telescopic card bottom block 3 is at the bottom end of the prefabricated component plate 2. Figure 3Then, the prefabricated component plate 2 can be moved by holding the support rod 34, so that the installation socket 31 on the telescopic card bottom block 3 is plugged into the basic steel bar 11, and finally, the prefabricated component plate 2 can be lowered downward, so that the telescopic card slot 21 at the bottom of the prefabricated component plate 2 can be clamped into the telescopic card bottom block 3. At the same time, the top of the basic steel bar 11 that has escaped from the installation socket 31 will be inserted into the first circular slot 23 in the telescopic card slot 21, and finally, the bolt screw 252 can be rotated by using a tool to insert the end of the bolt screw 252 into the installation slot 32, so that the basic steel bar 11 is connected to the installation socket 31 at the bottom of the prefabricated component plate 2.

[0031] The present application provides a fully assembled prefabricated component connection structure, such as Figure 1-Figure 6 As shown, the following steps are included: S1, when the need to use a fully assembled prefabricated component connection structure, first lift the prefabricated component plate 2 by the sling, and then rotate the hexagonal recessed bolt head 251 by the tool, at this time the telescopic card bottom block 3 moves downward by gravity out of the telescopic card slot 21; S2, then the U-shaped support rod 35 slides along the elliptical slot 22, and the U-shaped slides 352 at both ends of the arc-shaped card block 351 slide along the U-shaped support rod 35, so that the telescopic card bottom block 3 is suspended at the bottom end of the prefabricated component plate 2; S3, then make the installation socket 31 on the telescopic card bottom block 3 and the foundation steel bar 11 complete the plugging, and finally the prefabricated component plate 2 can be lowered downward, so that the foundation steel bar 11 and the installation socket 31 at the bottom of the prefabricated component plate 2 are connected.
