Description

Technical Field

[0001] This application relates to the field of building structure technology, specifically a high-strength bending-resistant reinforcement structure for beams and columns. Background Technology

[0002] Steel structures are widely used in construction, bridges, and other engineering fields due to their advantages such as high strength, lightweight, and flexibility. However, the connection points of steel beams are often weak points in the structure, susceptible to stress concentration, fatigue, and swaying. To improve the stability, load-bearing capacity, and safety of the structure, reinforcement structures are often installed at the steel beam connections to enhance the strength of the joints.

[0003] An existing patent (publication number: CN220747271U) discloses a steel beam connection reinforcement structure, belonging to the field of building structure technology. This steel beam connection reinforcement structure includes an upper beam, a lower beam, and a crossbeam connected in a cross shape; connecting components are provided at the connection points of the upper and lower beams; the crossbeams are arranged laterally on both sides of the connecting components, and reinforcement components are provided at the connection points of the crossbeams and the connecting components; the connecting components include a male connector sleeved on the bottom of the upper beam and a female connector sleeved on the top of the lower beam. Multiple connecting posts are provided at the bottom of the male connector, and multiple connecting grooves for engaging the connecting posts are provided at the top of the female connector; the male connector and the female connector are also fixedly connected by a locking component. This invention can solve the problem of insufficient reinforcement at steel beam connections, where the connection points may loosen and shift under external forces, leading to structural failure or even collapse.

[0004] The aforementioned comparative documents pointed out that fixing columns and beams solely through abutment can result in insufficient reinforcement. To further optimize the reinforcement strength, a high-strength bending-resistant reinforcement structure for beams and columns is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a high-strength bending-resistant beam and column reinforcement structure. The structure rationally distributes the positions of I-beam blocks and I-beam slots, and is combined with rationally distributed bolts to form a composite force transmission system, thereby further improving the reinforcement strength.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-strength bending-resistant beam-column reinforcement structure, comprising an upper beam, a lower beam, and a crossbeam, wherein the upper beam, lower beam, and crossbeam are connected by a reinforcement component, the reinforcement component comprising a reinforcement base sleeved on the top of the upper beam and a reinforcement top block sleeved on the bottom of the lower beam, wherein a first I-shaped block is fixedly connected to the bottom surface of the reinforcement top block, wherein a first I-shaped groove adapted to the first I-shaped block is formed on the upper surface of the reinforcement base, wherein four first positioning holes and two second positioning holes are formed on the outer surface of the first I-shaped block, wherein preset grooves are formed on both sides of the outer surfaces of the reinforcement base and the reinforcement top block, wherein one end of the crossbeam is inserted into two corresponding preset grooves, and one end of the crossbeam is formed with four third positioning holes and two fourth positioning holes.

[0007] The above scheme achieves multi-path force transmission through the reinforcement components, significantly improving reinforcement strength. Axial pressure is directly transmitted through the contact surface of the first I-beam block and the first I-beam groove. Combined with the multi-directional locking effect of the first positioning bolt and the first positioning screw on the first I-beam groove, the first positioning bolt, the first positioning screw, and the first I-beam groove can jointly bear the shear force. At the same time, the crossbeam is directly inserted into the two corresponding preset grooves, and the crossbeam is positioned by the second positioning bolt, the second positioning screw, and the second nut. This not only strengthens the connection between the reinforcement base and the reinforcement top block, but also optimizes the stress distribution, making the connection between the upper beam, the lower beam, and the crossbeam more secure.

[0008] Furthermore, a first rubber pad is fixedly connected to the bottom surface of the reinforcing top block.

[0009] The above solution improves the vibration resistance between the reinforced base and the reinforced top block by setting the first rubber pad, further optimizing the stability of the structure.

[0010] Furthermore, the inner wall of the first I-shaped groove is threaded with four first positioning bolts and two first positioning screws, and one end of each first positioning screw is threaded with a first nut.

[0011] The above scheme allows for convenient positioning of other components using the first positioning bolt and the first positioning screw. The first nut further limits the state of the first positioning screw, thereby improving the positioning effect of the first nut.

[0012] Furthermore, the outer surface of the first positioning bolt is threaded to the inner wall of the first positioning hole, and the first positioning screw is threaded to the inner wall of the second positioning hole.

[0013] The above scheme defines the relationship between the first positioning hole and the first positioning bolt, enabling the first positioning bolt to be screwed into the first positioning hole. It also defines the relationship between the first positioning screw and the second positioning hole, enabling the first positioning screw to be screwed into the second positioning hole. This allows the first I-shaped block to be positioned in the first I-shaped groove.

[0014] Furthermore, the inner walls of the four preset slots are each threaded with two second positioning bolts and one second positioning screw, and one end of each second positioning screw is threaded with a second nut.

[0015] The above scheme allows for convenient positioning of other components via the second positioning bolt and the second positioning screw, while the second nut further limits the state of the second positioning screw.

[0016] Furthermore, the outer surface of the second positioning bolt is threaded to the inner wall of the third positioning hole, and the outer surface of the second positioning screw is threaded to the inner wall of the fourth positioning hole.

[0017] By defining the relationship between the second positioning bolt and the third positioning hole, the second positioning bolt can be screwed into the third positioning hole. By defining the relationship between the second positioning screw and the fourth positioning hole, the second positioning screw can be screwed into the third positioning hole. This allows the crossbeam to be stably installed in the preset groove between the reinforcing base and the reinforcing top block.

[0018] Furthermore, the upper beam, lower beam, and crossbeam are provided with evenly distributed diagonal bracing steel on their exterior, and each diagonal bracing steel is fixedly connected to a second rubber pad at both ends.

[0019] The above solution improves the vibration resistance of the device by adding a second rubber pad, making it more practical.

[0020] Furthermore, each of the diagonal bracing steels is installed between the upper beam, lower beam, and crossbeam via two corresponding second rubber pads.

[0021] The above scheme uses diagonal bracing steel and a second rubber pad to reinforce the connection between the upper beam, lower beam, and crossbeam, which can convert horizontal force into axial force and significantly improve the structure's resistance to lateral displacement through the principle of triangular stability.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This high-strength bending-resistant beam and column reinforcement structure achieves multi-path force transmission through its reinforcement components, significantly improving reinforcement strength. Axial pressure is directly transmitted through the contact surface of the first I-beam block and the first I-beam groove. Combined with the multi-directional locking effect of the first positioning bolt and the first positioning screw on the first I-beam groove, the first positioning bolt, the first positioning screw, and the first I-beam groove jointly bear shear force. Simultaneously, the crossbeam is directly inserted into the two corresponding pre-set grooves, and positioned using the second positioning bolt, the second positioning screw, and the second nut. This not only strengthens the connection between the reinforcement base and the top block but also optimizes stress distribution, making the connections between the upper beam, lower beam, and crossbeam more robust. Finally, the addition of diagonal bracing steel and the second rubber pad further optimizes the bending resistance of the structure, making it more practical. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes a high-strength bending-resistant beam-column reinforcement structure, comprising an upper beam 1, a lower beam 2, and a crossbeam 3. The upper beam 1, lower beam 2, and crossbeam 3 are connected by a reinforcement component 4. The upper beam 1, lower beam 2, and crossbeam 3 are provided with uniformly distributed diagonal bracing steels 5 on their exterior. Each diagonal bracing steel 5 has a second rubber pad 6 fixedly connected to both ends. The second rubber pad 6 can improve the vibration resistance of the device and make it more practical. Each diagonal bracing steel 5 is installed between the upper beam 1, lower beam 2, and crossbeam 3 through two corresponding second rubber pads 6. The diagonal bracing steels 5 and the second rubber pads 6 are used to diagonally reinforce the connection between the upper beam 1, lower beam 2, and crossbeam 3, which can convert horizontal force into axial force and significantly improve the structure's resistance to lateral displacement through the principle of triangular stability.

[0034] Please see Figure 3 , Figure 4 and Figure 6The reinforcing component 4 includes a reinforcing base 401 sleeved on the top of the upper beam 1 and a reinforcing top block 402 sleeved on the bottom of the lower beam 2. A first I-beam block 403 is fixedly connected to the bottom surface of the reinforcing top block 402. A first I-beam groove 404, adapted to the first I-beam block 403, is formed on the upper surface of the reinforcing base 401. Inserting the first I-beam block 403 into the first I-beam groove 404 creates a direct pressure-bearing and force-transmitting path, bearing most of the axial pressure. A first rubber pad 410 is fixedly connected to the bottom surface of the reinforcing top block 402. Through the setting of the first... Rubber pad 410 can improve the vibration resistance between the reinforced base 401 and the reinforced top block 402, further optimizing the stability of the structure. The inner wall of the first I-shaped groove 404 is threaded with four first positioning bolts 407 and two first positioning screws 408. One end of each first positioning screw 408 is threaded with a first nut 409. The first positioning bolts 407 and first positioning screws 408 facilitate the positioning of other components, and the first nuts 409 further control the position of the first positioning screws 408. The positioning effect of the first nut 409 is improved by defining the position. The outer surface of the first I-shaped block 403 has four first positioning holes 405 and two second positioning holes 406. The outer surface of the first positioning bolt 407 is threaded to the inner wall of the first positioning hole 405, and the first positioning screw 408 is threaded to the inner wall of the second positioning hole 406. This defines the relationship between the first positioning hole 405 and the first positioning bolt 407, allowing the first positioning bolt 407 to be screwed into the first positioning hole 405, and defining the relationship between the first positioning screw 408 and the second positioning hole 406. The relationship between the holes 406 allows the first positioning screw 408 to be screwed into the second positioning hole 406, thereby positioning the first I-shaped block 403 in the first I-shaped groove 404. In this way, the first I-shaped block 403 can be positioned in the first I-shaped groove 404 from multiple directions. When the upper beam 1 and the lower beam 2 are under pressure, the first positioning bolt 407, the first positioning screw 408 and the first nut 409 can jointly bear the shear force, realizing a dual force transmission path, directly bearing pressure and friction to resist shear, and improving safety redundancy.

[0035] Please see Figure 3 , Figure 5 and Figure 6Both sides of the outer surface of the reinforcing base 401 and the reinforcing top block 402 are provided with preset grooves 411. One end of the crossbeam 3 is inserted into two corresponding preset grooves 411. One end of the crossbeam 3 is provided with four third positioning holes 412 and two fourth positioning holes 413. The inner walls of the four preset grooves 411 are threaded with two second positioning bolts 414 and one second positioning screw 415. One end of each second positioning screw 415 is threaded with a second nut 416. The second positioning bolts 414 and the second positioning screw 415 facilitate the positioning of other components. The second nut 416 further limits the state of the second positioning screw 415. The outer surface of the second positioning bolt 414 is threaded to the inner wall of the third positioning hole 412, and the outer surface of the second positioning screw 415 is threaded to the inner wall of the fourth positioning hole 413. The threaded connection, by defining the relationship between the second positioning bolt 414 and the third positioning hole 412, allows the second positioning bolt 414 to be screwed into the third positioning hole 412. By defining the relationship between the second positioning screw 415 and the fourth positioning hole 413, the second positioning screw 415 can be screwed into the third positioning hole 412. This allows the crossbeam 3 to be stably installed in the preset groove 411 between the reinforcing base 401 and the reinforcing top block 402. In this way, based on the reinforcement of the connection between the reinforcing base 401 and the reinforcing top block 402, the crossbeam 3 can be stably installed between the reinforcing base 401 and the reinforcing top block 402. One end of the crossbeam 3 cooperates with the second positioning bolt 414, the second positioning screw 415 and the second nut 416 to clamp the crossbeam 3 inside the corresponding two preset grooves 411, forming a composite anti-bending mechanism, which is more practical.

[0036] In this embodiment, a high-strength bending-resistant beam-column reinforcement structure achieves multi-path force transmission through the reinforcement component 4, significantly improving the reinforcement strength. Axial pressure is directly transmitted through the contact surface of the first I-beam block 403 and the first I-beam groove 404. Combined with the multi-directional locking effect of the first positioning bolt 407 and the first positioning screw 408 on the first I-beam groove 404, the first positioning bolt 407, the first positioning screw 408, and the first I-beam groove 404 jointly bear the shear force. Simultaneously, the crossbeam 3 is directly inserted into the two corresponding preset grooves 411, and positioned using the second positioning bolt 414, the second positioning screw 415, and the second nut 416. This not only strengthens the connection between the reinforcement base 401 and the reinforcement top block 402 but also optimizes the stress distribution, making the connection between the upper beam 1, the lower beam 2, and the crossbeam 3 more robust. Finally, the addition of the diagonal bracing steel 5 and the second rubber pad 6 optimizes the bending resistance of the structure, making it more practical.

[0037] The working principle of the above embodiment is as follows: When the upper beam 1 and the lower beam 2 are subjected to vertical pressure, the first I-shaped block 403 at the bottom of the reinforcing top block 402 is inserted into the first I-shaped groove 404 at the top of the reinforcing base 401. The first I-shaped block 403 and the bottom plane of the first I-shaped groove 404 are in close contact, forming a direct pressure transmission path, which bears most of the axial pressure. The remaining load is transmitted through the frictional resistance generated by the pre-tightening force between the first positioning bolt 407, the first positioning screw 408 and the first nut 409. The clamping force applied by the first positioning bolt 407, the first positioning screw 408 and the first nut 409 causes a certain frictional force to be generated on the contact surface. The beam 3 effectively resists shear force. When the beam 3 is bent or the structure is subjected to lateral force, the mating surfaces of one end of the beam 3 and the two preset grooves 411 are pressed together by the second positioning bolt 414, the second positioning screw 415 and the second nut 416 to form a shear-resistant interface, preventing horizontal slippage. After the beam 3 is inserted into the combined preset groove 411 on the side of the reinforcing base 401 and the reinforcing top block 402, the penetrating second positioning bolt 414, the second positioning screw 415 and the second nut 416 apply multi-directional pressure to clamp the beam 3 in the groove, forming a composite bending resistance mechanism. Finally, the installed diagonal bracing steel 5 can convert the horizontal force into axial force, further reducing the bending moment stress in the node area.
