Description

Technical Field

[0001] This utility model relates to the field of steel structures, and more specifically, to a seismic connection structure for steel structures. Background Technology

[0002] Steel structure is a building structure system that uses steel as the main load-bearing component and is assembled through welding, bolting, riveting, and other methods. Leveraging the advantages of steel's high strength, high toughness, lightweight, and industrial production capabilities, it is widely used in engineering fields such as buildings, bridges, industrial plants, large stadiums, and towers. It is one of the important types of modern engineering structures. The tensile, compressive, and shear strengths of steel are far higher than those of traditional materials such as concrete and wood. Therefore, under the same load requirements, steel structure components are more slender, significantly reducing the structure's self-weight. Steel has good plasticity and toughness, allowing it to deform under stress without sudden fracture. Under dynamic loads such as earthquakes and strong winds, it can absorb energy through its own deformation, making its seismic performance far superior to that of brittle concrete structures. A search revealed an existing patent (publication number: CN222541650U) that discloses a connection structure for an H-shaped steel structure, comprising interconnected steel columns and an H-shaped steel structure. The steel columns are vertically arranged, and the H-shaped steel structure is horizontally arranged. The key feature is that a connecting plate is fixedly installed at the end of the H-shaped steel structure by a first bolt. A fixing sleeve is slidably fitted onto the outside of the H-shaped steel structure. The fixing sleeve is fixedly connected to the steel column by a second bolt. A receiving groove is provided at the end of the fixing sleeve. The connecting plate is partially pressed and fixed within the space enclosed by the steel column and the receiving groove. Only the first and second bolts are needed to fix the steel column and the H-shaped steel structure together, eliminating the need for welding, thus saving costs. Furthermore, it facilitates disassembly and ensures the H-shaped steel structure can be reused. The inventors discovered the following problems with the existing technology during the development of this utility model: In existing seismic connection structures for steel structures, the steel columns and H-shaped steel structures are connected by only the first and second bolts. This single-point fixing method will result in insufficient connection strength. At the same time, no auxiliary support components are set at the connection point, which lacks effective shear and tensile buffering when under stress, thereby weakening the overall seismic performance. In addition, during the installation process, the bolt hole positions need to be manually aligned, and the positioning accuracy cannot be controlled, which increases the difficulty of operation and is also prone to affecting the connection stability due to hole position deviation, thus reducing construction efficiency. Therefore, a seismic connection structure for steel structures is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seismic connection structure for steel structures to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a seismic connection structure for steel structures, comprising a support beam, fixed side plates on both sides of the support beam, fixed supports fixedly connected to the opposite sides of the two fixed side plates, a support beam on one side of one fixed support, a reinforcing component on one side of the support beam, a limiting block fixedly connected to the bottom end of the support beam, a limiting hole on the bottom surface of the fixed support, the outer surface of the limiting block fitting the inner wall of the limiting hole, two fixing plates fixedly connected to the outer surface of the support beam, two sets of threaded grooves on the opposite sides of the two fixing plates, two sets of first through holes on the outer surface of the fixed support, two fixing screws on the outside of the fixed support, the outer surface of the fixing screws fitting the inner wall of the threaded grooves, positioning holes on the bottom surfaces of the two fixed side plates, and two positioning plates fixedly connected to the outer surface of the support beam, the outer surfaces of the two positioning plates respectively contacting the inner walls of the two positioning holes.

The lower part of the upper mounting plate is provided with a fixing nut, and the outer surface of the fixing nut is adapted to the outer surface of the threaded fixing rod.

[0009] Preferably, an anti-vibration buffer pad is provided between the support beam and the fixed side plate. The anti-vibration buffer pad is made of nitrile rubber and has a thickness of 5-10mm.

[0010] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this seismic connection structure for steel structures allows for initial positioning by directly embedding the positioning plate into the bottom surface of the fixed side plate through positioning holes. Furthermore, locking screws passing through the second and third through holes, along with locking nuts, ensure the connection stability between the fixed side plate and the support beam. Limiting blocks inserted into the limiting holes of the fixed support limit the support beam and align it with the first through hole and threaded groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] As attached Figures 1-5 The diagram illustrates a seismic connection structure for steel structures, comprising a support beam 1, with fixed side plates 2 on both sides of the support beam 1. Fixed supports 3 are fixedly connected to the sides of the two fixed side plates 2 that are far apart from each other. A support beam 4 is provided on one side of each fixed support 3. A reinforcing component 5 is provided on one side of the support beam 1. A limiting block 11 is fixedly connected to the bottom end of the support beam 4. A limiting hole 10 is formed on the bottom surface of the fixed support 3. The outer surface of the limiting block 11 is adapted to the inner wall of the limiting hole 10. Two fixing plates 16 are fixedly connected to the outer surface of the support beam 1. Two sets of threaded grooves 17 are provided on the side of the two fixed plates 16 that are far apart from each other. Two sets of first through holes 13 are provided on the outer surface of the fixed support 3. Two fixing screws 15 are provided on the outside of the fixed support 3, and the outer surface of the fixing screws 15 is adapted to the inner wall of the threaded grooves 17. Positioning holes 8 are provided on the bottom surface of the two fixed side plates 2. Two positioning plates 9 are fixedly connected to the outer surface of the support beam 1. The outer surfaces of the two positioning plates 9 are in contact with the inner walls of the two positioning holes 8 respectively. In addition, the components and bolts of this application are all made of high-strength corrosion-resistant materials.

[0020] As can be seen from the above description, this utility model has the following beneficial effects: the positioning hole 8 on the bottom surface of the fixed side plate 2 can be directly embedded into the surface of the positioning plate 9 for preliminary positioning. In addition, the locking screw 14 passes through the second through hole 18 and the third through hole 12 and is fixed with the locking nut 19 to ensure the connection stability of the fixed side plate 2 and the support beam 1. The limiting block 11 is inserted into the limiting hole 10 of the fixed support 3 to realize the limiting of the support beam 4 and the alignment with the first through hole 13 and the threaded groove 17. The connection between the fixed support 3 and the support beam 1 can be completed by directly screwing in the fixing screw 15, without complicated hole alignment operations, which reduces the construction difficulty. Example

[0021] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figures 1-5As shown, in a preferred embodiment, each of the two fixed side plates 2 has multiple second through holes 18 on one side, and the outer surface of the support beam 1 has multiple third through holes 12. A locking screw 14 is provided on one side of the fixed side plate 2, and a locking nut 19 is provided on the outside of the support beam 1. The outer surface of the locking screw 14 is adapted to the inner ring of the locking nut 19, and the diameter of the locking screw 14 is smaller than the inner diameter of the second through holes 18 and the third through holes 12. The outer surfaces of the support beam 1, the support crossbeam 4, and the fixed support 3 are all coated with an anti-corrosion coating, which is an epoxy resin coating. An anti-vibration buffer pad 20 is provided between the support beam 1 and the fixed side plate 2. The support beam 1, support beam 4, and fixed support 3 are made of nitrile rubber and the thickness of the shock-absorbing pad 20 is 5-10mm. Furthermore, the second through hole 18 and the third through hole 12 provide a passage for the locking screw 14. After the locking screw 14 passes through the two through holes, it is tightened with the locking nut 19 to form a multi-point fixation, avoiding the problem of easy loosening of single-point connection. At the same time, the epoxy resin anti-corrosion coating on the surface of the support beam 1, support beam 4, and fixed support 3 can isolate the corrosion of humid and acidic / alkaline environments and extend the service life of the components. In addition, the nitrile rubber shock-absorbing pad 20 between the support beam 1 and the fixed side plate 2 can absorb impact energy through its own deformation, reducing structural damage under loads such as earthquakes.

[0022] like Figures 1-5 As shown, in a preferred embodiment, the reinforcement component 5 includes a reinforcement support plate 501. A side mounting plate 502 and an upper mounting plate 503 are fixedly installed on both sides of the reinforcement support plate 501, respectively. One side of both the side mounting plate 502 and the upper mounting plate 503 has a mounting through hole 505. A threaded fixing groove 6 is formed on the outer surface of the support beam 1. A fixing bolt 506 is provided on one side of the side mounting plate 502, and the outer surface of the fixing bolt 506 is adapted to the inner wall of the threaded fixing groove 6. A threaded fixing rod 7 is fixedly connected to the bottom surface of the support beam 4. The diameter of the threaded fixing rod 7 is smaller than the inner diameter of the mounting through hole 505. A fixing bolt is provided below the upper mounting plate 503. The outer surface of the fixing nut 504 is adapted to the outer surface of the threaded fixing rod 7. Furthermore, the side mounting plate 502 is connected to the threaded fixing groove 6 of the support beam 1 by fixing bolts 506, so as to realize the firm fixation of the reinforcement component 5 and the support beam 1. The threaded fixing rod 7 on the bottom surface of the support beam 4 passes through the mounting through hole 505 of the upper mounting plate 503 and can be locked by fixing nut 504, so that the reinforcement component 5 and the support beam 4 can form a reliable connection. This design allows the support beam 1, the support beam 4 and the reinforcement component 5 to form a triangular support structure, which enhances the overall shear and tensile resistance, effectively disperses the load and avoids local stress concentration.

[0023] The working process of this utility model is as follows: When using this seismic connection structure for steel structures, firstly, the support beam 1 is connected to the fixed side plate 2. The positioning plate 9 on the surface of the support beam 1 is directly embedded into the positioning hole 8 on the bottom surface of the fixed side plate 2, which can quickly complete the initial positioning. Then, the locking screw 14 is passed through the second through hole 18 of the fixed side plate 2 and the third through hole 12 of the support beam 1, and tightened with the locking nut 19, which can firmly connect the support beam 1 and the fixed side plate 2. Then, when installing the support beam 4, the limiting block 11 at its bottom end is inserted into the limiting hole 10 on the bottom surface of the fixed support 3, which can limit the position during installation. At the same time, the first through hole 13 is aligned with the thread groove 17 of the fixed plate 16, and the fixing screw 15 is screwed in to realize the connection between the fixed support 3 and the support beam 1. Next, the side mounting plate 502 of the reinforcing support plate 501 is connected to the threaded fixing groove 6 of the support beam 1 by fixing bolts 506, while the upper mounting plate 503 is fitted into the threaded fixing rod 7 of the support beam 4 through the mounting through hole 505 and locked with the fixing nut 504. This enables the support beam 1 and the support beam 4 to form a triangular support structure, which enhances the shear and tensile resistance. At the same time, the seismic buffer pad 20 between the support beam 1 and the fixed side plate 2 reduces structural deformation and improves the overall seismic stability. This is the working process and working principle of the device.

[0024] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
