Each connecting box has space for fastener installation. The top of each connecting box has a second mounting hole for connecting internal column reinforcement bars, with each second mounting hole corresponding to one of the first mounting holes. The fastener is located inside the connecting box and is used to fix the column base bolt.

[0005] A further improvement of the connection structure of the prefabricated component of this utility model is that the second mounting hole is a threaded hole adapted to the bottom thread of the steel bar inside the column.

[0006] A further improvement of the connection structure of the prefabricated assembly component of this utility model is that the bottom of the steel bar inside the column is provided with an external thread, and the bottom of the steel bar inside the column passes through the second mounting hole and is connected to the connection box by a nut.

[0007] A further improvement of the connection structure of the prefabricated assembly component of this utility model is that the top of the connection box is provided with a cylindrical connection section, and the second mounting hole is provided on the connection section.

[0008] A further improvement of the connection structure of the prefabricated assembly component of this utility model is that the plurality of the first mounting holes are located near the edge of the base plate.

[0009] A further improvement of the connection structure of the prefabricated assembly component of this utility model is that the fastener includes an adjusting nut and a first fastening nut.

The bottoms of the multiple connection boxes 8 are fixed to the base plate 6, and each connection box 8 has a connection hole 10 at its bottom, corresponding to the first mounting holes. The connection box 8 has space for fastener installation. The top of each connection box 8 has a second mounting hole 5 for connecting internal column reinforcement bars, with each second mounting hole 5 corresponding to one of the first mounting holes. The fastener is located inside the connection box 8 and is used to fix the column base bolt.

[0021] Specifically, the connection structure of this utility model is not only applicable to the connection between the vertical precast component 3 and the foundation 1, but also applicable to the connection between the vertical precast component 3 and other precast components, such as the connection between columns. The vertical precast component 3 can be a column or a wall, etc. The column base bolt 2 is an anchor bolt anchored in the middle and lower part of the foundation 1. The upper part of the column base bolt 2 is threaded, and the bottom of the column reinforcement 4 is threaded. The connection box 8 is columnar and has a certain shear resistance and deformation resistance. The connection box 8 is provided with an opening for fastener installation. The opening of the connection box 8 faces outward, which facilitates the installation of fasteners. The foundation 1 and the vertical precast component 3 are fixed simultaneously inside the connection box 8, solving the connection problem between the concrete vertical component and the foundation 1.

[0022] Preferably, the plurality of the first mounting holes are located near the edge of the base plate 6, thereby facilitating the tightening of the column base bolts 2 and the internal steel bars 4.

[0023] In this embodiment, the base plate 6 is rectangular, and each of the four corners of the base plate 6 is provided with a first mounting hole. There are at least four connecting boxes 4, and one connecting box 4 is fixed at each of the four corners of the base plate 6 corresponding to the position of the first mounting hole. The dimensions of the base plate 6 are the same as the dimensions of the column cross-section, thus facilitating production, transportation, and installation. In this embodiment, there are eight first mounting holes, with one mounting hole between any two adjacent corner first mounting holes. The base plate 6 can also be selected as rectangular, circular, polygonal, or a U-shaped structure with a central open section, depending on the cross-sectional form of the vertical prefabricated component 3.

[0024] Preferably, the fastener includes an adjusting nut 11 and a first fastening nut 9. The adjusting nut 11 is used to connect to the column base bolt and is located on the bottom surface of the base plate 6. The first fastening nut 9 is used to connect to the column base bolt and is located inside the connecting box 8. Multiple fasteners are used, each corresponding to a specific first mounting hole. By adjusting the position of the adjusting nut 11 on the column base bolt 2, the level and elevation of the base plate 6 are controlled, thereby controlling the verticality of the vertical prefabricated component 3. The opening on the connecting box 8 provides space for tightening the first fastening nut 9.

[0025] In the first embodiment, the second mounting hole 5 is a threaded hole adapted to the bottom thread of the column reinforcement, thereby connecting the column reinforcement to the connecting box 8 through the thread.

[0026] In embodiment 2, the bottom of the column reinforcement bar is provided with external threads, and the bottom of the column reinforcement bar 4 passes through the second mounting hole 5 and is connected to the connecting box 8 through a nut.

[0027] Preferred, such as Figure 3 As shown, the top of the connecting box 8 is provided with a cylindrical connecting section 7, and the second mounting hole 5 is provided on the connecting section 7. Specifically, the top of the connecting box 8 has an opening, and the second mounting hole 5 corresponds to the connecting hole 10, so that the steel bars inside the column can be directly inserted into the connecting box 8.

[0028] This utility model relates to a connection structure for prefabricated components. Column base bolts are fixed to the base plate 6 using fasteners, and the internal reinforcing bars of the column are connected to the second mounting holes 5. The first and second mounting holes 5 on the base plate 6 and top plate correspond to each other, ensuring the verticality of the prefabricated components. The length of the column base bolts and internal reinforcing bars extending into the connection box 8 can be adjusted using fasteners, thereby adjusting the elevation of the vertical prefabricated components. This solves the problems of force transmission between the longitudinal reinforcing bars of the column and the foundation, and other prefabricated components, as well as the installation deviation of the column base bolts between the longitudinal reinforcing bars of the column and the foundation or other prefabricated components, and the control of the elevation and verticality of the vertical prefabricated components in existing connection structures during installation. The connection structure of this utility model has the same cross-sectional dimensions as the column, facilitating production, transportation, and installation, and ensuring reliable force transmission to the reinforcing bars.
