[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-4 The utility model provides an embodiment: a shear-resistant steel structure node structure, including two steel beams 1, one side of the two steel beams 1 is welded and fixed with a connecting plate 2, and the two sides of the upper and lower ends of the two steel beams 1 are welded and fixed with shear mechanisms 4; reinforcing mechanisms 5 are fixedly arranged around the middle position of the two shear mechanisms 4, and the four corners of the upper and lower ends of the four reinforcing mechanisms 5 are fixedly arranged with first fixing plates 6, and the four corners of the upper and lower ends of the steel beams 1 are fixedly arranged with second fixing plates 7.

[0032] The node mechanism connects two connecting plates 2 through a first fastening bolt 3, and the connecting plate 2 is fixed to one side of the steel beam 1 by welding. The steel beam 1 is connected by the two connecting plates 2. The shear resistance performance of the node mechanism can be effectively enhanced by the set shear resistance mechanism 4, and the overall strength of the node mechanism can be enhanced by the set reinforcement mechanism 5, thereby effectively protecting the shear resistance mechanism 4. The first fixing plate 6 and the second fixing plate 7 are used in combination to fix the reinforcement mechanism 5 inside the steel beam 1.

[0033] Reference Figure 1-3 , the first fastening bolts 3 are threadedly sleeved on one side of the two connecting plates 2, the second fastening bolts 8 are threadedly sleeved on the upper ends of the eight first fixing plates 6, the four anti-shear mechanisms 4 include a fixing seat 401 and a reinforcing plate 402, the upper ends of the four fixing seats 401 are provided with sliding grooves 403, one side of the four reinforcing plates 402 is fixedly provided with a moving block 404, the inside of the four sliding grooves 403 is slidably provided with a slider 405, one side of the four moving blocks 404 is fixedly provided with a connecting block 406, and one side of the inside of the four fixing seats 401 is fixedly provided with a spring damper 407.

[0034] The node structure connects the connecting plate 2 by means of the first fastening bolt 3, and the second fastening bolt 8 fixes the first fixing plate 6 and the second fixing plate 7. The shear mechanism 4 fixes the fixing seat 401 and the reinforcing plate 402 on the steel beam by welding, and a slide groove 403 is provided inside the fixing seat 401. The moving block 404 drives the slider 405 to slide inside the slide groove 403. The connecting block 406 connects the spring damper 407 and the moving block 404. When the beam 1 is subjected to pressure, the reinforcing plate 402 initially resists the pressure. When the reinforcing plate 402 is deformed, it drives the moving block 404 and the connecting block 406 to move and squeeze the spring damper 407. The spring damper 407 buffers the pressure on the node mechanism, thereby effectively extending the service life of the node mechanism.

When the node mechanism is in use, the shear mechanism 4 will squeeze the moving block 404 when it is subjected to shear stress through the reinforcing plate 402, and when the moving block 404 is squeezed and moved, it can drive the slider 405 to slide The groove 403 slides inside, and drives the connecting block 406 to move and squeeze the spring damper 407. The pressure on the spring damper 407 can be buffered, thereby effectively extending the service life of the node mechanism and the steel beam 1. In addition, through the provided reinforcing mechanism 5, when the reinforcing mechanism 5 is subjected to the vertical shear force from the steel beam 1 through the first support rod 501, it will move toward the inside of the second support rod 504 and squeeze the spring column 503. The spring column 503 buffers the pressure received, thereby protecting the steel beam 1, and indirectly protecting the shear mechanism 4, further improving the overall service life of the node structure.
