The pillars are simply supported beams, which provide support for the beams on the road bridge. With the rapid development of my country's construction industry, the requirements for the stability of buildings are increasing. Therefore, the beam-column connection nodes in the frame structure of a building are the most critical structures, and the original structural columns and simply supported beams are also connected and installed through rigid connection structures.

[0003] In existing technology, structural columns and simply supported beams are placed and installed through connecting supports, which contain steel sections and stirrups. When connecting, rigid connections are made by expansion bolts or welding. However, in actual use, connections made solely by expansion bolts or welding have poor firmness and stability, which can easily affect subsequent use and is inconvenient to use.

The simply supported beam body 3 is provided with guide units that are adapted to the guide grooves.

[0018] With the above structure, during use, the lower fixing block 9 and the upper fixing block 10 can be inserted to allow it to move only up and down. Then, the lower fixing block 9 and the upper fixing block 10 can be fixed and limited by the fixing reinforcement component, thereby connecting the original structural column body 1 and the simply supported beam body 3.

[0019] The fixing and reinforcing assembly includes three threaded holes respectively opened on both sides of the connecting block 2, and expansion bolts 5 are threadedly installed on the multiple threaded holes. The sides of the two lower fixing blocks 9 and the two upper fixing blocks 10 are each provided with three clearance holes that are adapted to the expansion bolts 5.

The multiple expansion bolts 5 pass through the multiple through holes respectively. The sides of the connecting block 2 are fixed with two grouting ports 7. The connecting block 2 is provided with a reinforcing unit.

[0020] In this scheme, the lower fixing block 9 and the upper fixing block 10 can be fixed by expansion bolts 5 and grouting port 7.

[0021] Specifically, the expansion bolts 5 can limit the lower fixing block 9 and the upper fixing block 10, and then the grouting port 7 can be used for grouting, thereby fixing and limiting the internal components and preventing loosening.

[0022] The reinforcing unit includes multiple first reinforcing plates 6 disposed above the original structural column body 1. Second reinforcing plates 13 and third reinforcing plates 14 are installed on the sides of the multiple first reinforcing plates 6. Three insertion holes adapted to the second reinforcing plates 13 are opened on the mutually distant sides of the connecting block 2, the sides of the two lower fixing blocks 9 and the sides of the two upper fixing blocks 10. Multiple reinforcing grooves adapted to the third reinforcing plates 14 are fixed at the mutually distant ends of the original structural column body 1. Reinforcing bars 15 are installed on the sides of the multiple first reinforcing plates 6. Three moving holes adapted to the reinforcing bars 15 are opened on the inner walls of the mutually distant sides of the connecting block 2, the sides of the two lower fixing blocks 9 and the two upper fixing blocks 10 and the sides of the two slots. Movable holes adapted to the expansion bolts 5 are opened on the sides of the multiple first reinforcing plates 6.

[0023] In this scheme, the installation of the first reinforcing plate 6, the second reinforcing plate 13, the third reinforcing plate 14, and the reinforcing bar 15 increases the fixing effect.

[0024] Specifically, during use, the fixing area is increased by the first reinforcing plate 6, the second reinforcing plate 13, and the third reinforcing plate 14, thereby increasing the fixing effect of the lower fixing block 9 and the upper fixing block 10. The strength of the concrete after pouring is increased by the setting of the steel bar 15.

[0025] The guide assembly includes three guide blocks 11 fixedly installed at the bottom of the simply supported beam body 3, and each of the three guide blocks 11 has a movable plate 12 connected to the guide groove installed at its bottom.

[0026] In this design, the guide block 11 and the movable plate 12 serve a certain guiding function.

[0027] Specifically, the guide block 11 and the movable plate 12 enable the simply supported beam body 3 to quickly align with the connecting block 2. At the same time, the movable plate 12 can cooperate with the expansion bolts 5 to enhance the fixing effect.

[0028] The sealing assembly includes a first loop block 4 fixedly installed at the bottom of the simply supported beam body 3, and a second loop block 8 installed at the bottom of the connecting block 2. The four inner walls of the first loop block 4 are in contact with the four outer walls of the second loop block 8.

[0029] In this design, the first loop block 4 and the second loop block 8 are used to achieve a certain sealing effect.

[0030] Specifically, by setting the first loop block 4 and the second loop block 8, welding can be performed during use to increase the connection effect. At the same time, the connection between the connecting block 2 and the simply supported beam body 3 is made tighter, preventing concrete from moving out of the gap during grouting.

[0031] The sides of the two lower fixing blocks 9 and the two upper fixing blocks 10 are provided with reinforcing ribs 16.

[0032] Specifically, the strength of the lower fixing block 9 and the upper fixing block 10 is increased by setting the reinforcing rib 16.

[0033] In summary: When using this utility model, the simply supported beam body 3 is first lifted by an external hoisting tool. At this time, the guide block 11 and the moving plate 12, together with the guide groove, play a certain guiding role, so that the fixing holes of the two upper fixing blocks 10 on the simply supported beam body 3 are aligned with the two lower fixing blocks 9. After alignment, the simply supported beam body 3 is placed on top of the connecting block 2 by the hoisting tool. Then, the second reinforcing plate 13 and the third reinforcing plate 14 are respectively inserted into multiple insertion holes and reinforcing grooves through the first reinforcing plate 6. At this time, the lower fixing blocks 9 and the upper fixing blocks 10 is restricted and cannot move. Then, the expansion bolt 5 is bolted into the connecting block 2 through the threaded hole. The expansion bolt 5 will be screwed in and will pass through multiple clearance holes and press against the first reinforcing plate 6, thereby fixing the original structural column body 1 and the simply supported beam body 3. At the same time, the expansion bolt 5 will enter the guide groove to limit the moving plate 12, further strengthening the fixing effect. Then, grouting operation is performed in the connecting block 2 through the grouting port 7. After the mortar solidifies, it will fix and limit the internal components, prevent loosening, and greatly improve the connection stability.
