DETAILED DESCRIPTION

[0032] The structure of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0033] Example 1

[0034] A prefabricated beam-column connection structure, such as Figures 1 to 4 As shown, including a cylinder;

[0035] On the side wall of the column body 1, there is a crossbeam placement groove 3 for supporting the crossbeam 9. The crossbeam placement groove 3 is in a U shape, including a bottom plate and side plates on both sides of the bottom plate. At the ends of both side plates away from the bottom plate, there are guiding inclined surfaces 13 inclined towards the inside of the crossbeam placement groove 3. Through the provided guiding inclined surfaces 13, when placing the crossbeam 9, it can slide into the crossbeam placement groove 3 from the inclined surface, making the installation of the crossbeam 9 more convenient. Below the crossbeam placement groove 3 (bottom plate), there is a lower support member 2. The lower support member 2 includes a lower vertical plate and a triangular support plate. The lower vertical plate is flush with and fixed to the side wall of the column body 1. The lower vertical plate is fixedly connected to the crossbeam placement groove 3. The triangular support plate is arranged between the L-shaped plate formed by the lower vertical plate and the crossbeam placement groove 3 (bottom plate). The triangular support plate is fixedly connected to both the lower vertical plate and the crossbeam placement groove 3 (bottom plate) at the same time. There are two triangular support plates in total, and the two triangular support plates are parallel to each other and arranged at intervals. There are lower support member fixing holes on the lower vertical plate, and the lower support member fixing bolts pass through the lower support member fixing holes and are fixed on the column body 1;

[0036] On the side of the crossbeam placement groove 3 close to the column body 1, there are a pair of bidirectional threaded rod arrangement holes. The bidirectional threaded rod 4 is inserted into the two bidirectional threaded rod arrangement holes and the bidirectional threaded rod 4 penetrates through the crossbeam placement groove 3. On both sides of the bidirectional threaded rod 4, two sliders 5 are symmetrically arranged and threadedly connected. One side of the slider 5 is connected to the rotating plate 7 through the first connecting shaft 6. The ends of the two rotating plates 7 away from the slider 5 are simultaneously connected to the pushing plate 8 through the second connecting shaft. The pushing plate 8 is in contact with the end face of the crossbeam 9;

[0037] At the end of the bidirectional threaded rod 4 passing through the crossbeam placement groove 3, there is an operating handle. There is an operating handle card slot 12 on the operating handle that matches the end of the bidirectional threaded rod 4. The operating handle is inserted and fixed at the end of the bidirectional threaded rod 4 passing through the crossbeam placement groove 3 through the operating handle card slot 12. There is a fixed plug rod arrangement hole on the operating handle. The fixed plug rod 11 is inserted into the fixed plug rod arrangement hole. On the side wall of the crossbeam placement groove 3 where the operating handle is provided, there are several plug rod fixing holes 10 arranged around the circumference of the bidirectional threaded rod arrangement hole. The plug rod fixing holes 10 match the fixed plug rod 11. By operating the operating handle, the bidirectional threaded rod can be rotated. After adjusting to a certain position, the pushing plate 8 and the crossbeam 9 can be fixed by inserting the fixed plug rod 11 into the plug rod fixing holes 10. Of course, the tool head of an electric screwdriver can also be stuck inside through the operating handle card slot 12 to drive the rotation of the bidirectional threaded rod 4, thereby making it more labor-saving for construction workers to operate and making the pushing plate 8 squeeze the crossbeam 9 tighter;

[0038] An upper closing plate 14 matching the beam placement slot 3 is provided above the beam placement slot 3, and the upper closing plate 14 and the beam placement slot 3 form a square structure. Side connecting plates 15 are fixed on both sides of the upper closing plate 14, and the side connecting plates 15 extend downward to the outside of the beam placement slot 3. The corresponding positions of the beam placement slot 3 and the side connecting plates 15 are provided with matching side connecting plate fixing screw holes 16, and the side connecting plate fixing screws 17 pass through the connecting plate fixing screw holes 16 on both sides to fix the beam placement slot 3 and the side connecting plates 15. The side connecting plate fixing screws 17 penetrate from the outside of the side connecting plates 15. The end of the side connecting plate fixing screw 17 does not extend out of the inner surface of the beam placement groove 3 by inserting into the side connecting plate fixing screw hole 16. The end of the side connecting plate fixing screw 17 does not extend out of the end of the beam placement groove 3, so that after the beam 9 is placed, the side connecting plate fixing screw 17 can be tightened to avoid the side connecting plate fixing screw 17 from loosening due to obstruction by the beam 9. After tightening the beam 9, the upper closing plate 14 is covered and the side connecting plate fixing screw 17 is installed, thereby wrapping and fixing the end of the beam 9, making the beam 9 safer and more stable after installation.

[0039] The connection steps of the above-mentioned prefabricated assembled beam-column connection structure are as follows:

[0040] First, fix the lower support member 2 and the beam placement groove 3 on the column 1, then move the beam 9 up and place it inside the beam placement groove 3, and then rotate the two-way threaded rod 4 to make the push plate 8 tightly squeeze the beam 9. The position of the beam can be fixed by squeezing at both ends to prevent it from shaking. Then, when assembling the beam 9, some shorter beams 9 can be directly selected, and the beam 9 can be fixed through the device.

[0041] It has been verified that the prefabricated assembled beam-column connection structure of the utility model has a reasonable structural design. By rotating the two-way threaded rod to adjust the spacing between the two sliders on the two-way threaded rod, the angle between the rotating plate and the slider can be adjusted, and then the position of the push plate can be adjusted. The position of the beam can be fixed by squeezing at both ends to prevent it from shaking. This structure can greatly reduce the requirements for assembly accuracy while ensuring normal construction efficiency, and its structural stability is good. Compared with traditional connection structures, it has high redundancy and good adaptability, and can avoid on-site modification and processing operations to a large extent. When assembling beams, some shorter beams can be directly selected, and the beams can be fixed through the device, thereby effectively avoiding the reduction of the stress performance of the structure due to errors. It has high installation efficiency and good structural strength, and has good application prospects.
