[0028] According to the above technical solution, the top and bottom surfaces of the connecting plate and the mating plate are both rough surfaces, and the connecting plate and the mating plate are tightly fitted together.

[0029] According to the above technical solution, a crossbeam support assembly is provided on both sides of the column at the bottom of the L-shaped connecting seat, and the crossbeam support assembly includes a connecting sleeve;

[0030] The column has mating sleeves fixed at the bottom of the L-shaped connecting seat on both sides. A support plate is connected to the top of the mating sleeve.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. Equipped with tensile and seismic resistant components, the welding rod is tied to the steel bar in the column by passing the iron wire through the through hole. After welding and binding, the column can be poured with concrete. Under the dual effect of welding and iron wire binding, the installation stability of the L-shaped connector is enhanced. When an earthquake causes the weld between the welding rod and the steel bar in the column to break, the iron wire passing through the through hole can still ensure the connection between the welding rod and the steel bar in the column, thus enhancing the seismic resistance.

[0035] When the mating plates and connecting plates are subjected to external tension, the mating groove restricts the mating protrusion. With the help of tightening bolts, the connection between the connecting plates and mating plates is more stable. At the same time, the mating plates and connecting plates are stacked together. When the mating plates and connecting plates are subjected to external tension, they will be subjected to the opposite frictional force from other mating plates and connecting plates. The surfaces of the mating plates and connecting plates are rough, which increases the frictional force. In static friction, the magnitude of the frictional force is balanced with the applied tension force, so that the stacked mating plates and connecting plates have greater frictional force under a fixed friction coefficient, making them less likely to be pulled apart. With the connection and fixation of the tightening bolts, the tensile strength of the beam and column joint is further enhanced, and the seismic performance is better.

[0036] Meanwhile, the surface of the friction steel plate is also rough, the energy generated by the earthquake is consumed by the mutual friction between the friction steel plates, the anti-seismic ability is better, meanwhile, the arc-shaped strip is connected between the I-shaped steel and the connecting frame, the deformation of the arc-shaped strip can also consume the energy generated by the earthquake, further enhancing the anti-seismic ability, meanwhile, the arc-shaped strip can also strengthen the stable connection between the connecting frame and the I-shaped steel.

[0037] 2、Setting up the crossbeam support assembly, the fixed bolt cooperates with the connecting rod and the connecting groove to connect, so that the two butt joint sleeves can be more stably fixed on the outside of the stand column, the two-way screw rod is connected with the reinforcing rib, the connecting lug is sleeved on the outside of the reinforcing screw rod, the rotating adjusting screw tube moves along the outside of the adjusting screw rod, the connecting flat head is sleeved on both ends of the two-way screw rod, the fixed nut is used to fix the connecting flat head and the connecting lug, the top surface of the support plate on the top of the two butt joint sleeves is tightly attached to the bottom surface of the L-shaped connecting seat, the L-shaped connecting seat is supported, when the support plate is pressed by the crossbeam, under the connecting pulling action of the two-way screw rod, the connecting flat head, the adjusting screw rod, the adjusting screw tube, the connecting lug and the reinforcing screw rod, the expansion screw is used to further improve the compression resistance of the butt joint sleeve, at the same time, the two adjusting screw rods and the adjusting screw tubes on the same side are connected to form a triangular shape, the stability of the triangular shape is used to make the compression resistance of the butt joint sleeve stronger, at the same time, the position of the adjusting screw tube on the outside of the adjusting screw rod can be controlled according to the diameter of the stand column, the application range is increased.

[0038] 3、Through the combination of the steel-concrete structure beam-column joint component, the alignment condition is detected by using the photoelectric sensor during the combination, the width and depth of the non-welding gap at the combined position are detected by the laser displacement sensor after the combination, the appearance of the combined position of the combined component is detected, the internal steel bar distribution and cavity condition of the welding position at the combined position are detected by the ultrasonic sensor, and the strength of the combined component is detected, so as to understand the comprehensive condition of the combined component, and the combination effect and quality of the combined component are better.

[0039] In summary, compared with the support mode of the traditional steel bracket to the crossbeam, the crossbeam support assembly strengthens the support ability of the butt joint sleeve, so that the crossbeam in the tensile and anti-seismic assembly can be more stably fixed on the top of the support plate, the two assemblies cooperate with each other, the anti-seismic effect of the steel-concrete structure beam-column joint is better, the appearance, gap and strength of the combined component are detected, the comprehensive condition of the combined component can be more accurately mastered, and the quality of the combined component is improved.

[0084] At the same time, the surface of the friction steel plate 220 is also rough, when the earthquake occurs, the friction steel plate 220 rotates around the rotating screw rod 222, the friction steel plate 220 is rubbed with each other to consume the energy generated by the earthquake, so that the anti-seismic capacity is better, at the same time, the arc-shaped strip 223 is connected between the channel steel 221 and the connecting frame 219, the deformation of the arc-shaped strip 223 can also consume the energy generated by the earthquake, further enhancing the anti-seismic capacity, at the same time, the arc-shaped strip 223 can also strengthen the stable connection between the connecting frame 219 and the channel steel 221.
