Description

Technical Field

[0001] This invention relates to the field of steel structure joint reinforcement, and specifically to a steel structure joint reinforcement component and its installation method. Background Technology

[0002] Steel structures are building structures assembled using steel as the primary load-bearing material through welding, bolting, or riveting. They possess characteristics such as high strength, high rigidity, light weight, fast construction speed, and recyclability, and are widely used in industrial plants, high-rise buildings, long-span bridges, stadiums, and offshore platforms. Steel structure joints refer to the connection nodes between different steel components (such as beams, columns, trusses, and supports). These are critical areas for structural stress transmission, bearing and distributing complex multi-directional loads such as tension, compression, bending moment, shear force, and torque. Their design rationality directly determines the overall structure's seismic performance, wind resistance, and durability. To enhance the load-bearing capacity and failure resistance of joints, reinforcing components are often used for local reinforcement. These include stiffening ribs to increase web stability, connecting plates to expand the connection area, angle steel or channel steel for corner support, welded backing plates to distribute weld stress, high-strength bolts for reliable friction connections, and rivets or specialized connectors.

[0003] Strengthening components at steel structure joints effectively prevent brittle joint failure, fatigue crack propagation, or connection failure by increasing the moment of inertia of the cross section, improving the stiffness of the joint, dispersing stress concentration, enhancing connection reliability, or preventing local buckling. This ensures that the structure maintains its integrity and safety under extreme loads and is the core means of realizing the concept of strong joints and weak components in steel structure design.

[0004] Existing steel structure joint reinforcement components lack adaptive multi-dimensional reinforcement capabilities. This results in fixed-size reinforcement component designs that cannot adapt to beams of different specifications, requiring on-site cutting and modification. Furthermore, the use of unidirectional or bidirectional planar supports fails to form a three-dimensional stress system, making them prone to local instability under complex loads and limiting their load-bearing capacity. Over long-term use, vibrations in the steel structure can also cause the reinforcement components at the joints to loosen, requiring frequent inspection and maintenance.

[0005] Therefore, it is necessary to invent a reinforcing component for steel structure joints and its installation method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a reinforcing component for steel structure joints and its installation method. By enabling the reinforcing component to have adaptive multidimensional strengthening capabilities, stress distribution can be made more uniform, effectively suppressing fatigue cracks caused by stress concentration, maintaining long-term stable contact, and ensuring the stability of the steel structure joint. This solves the problem that existing technologies lack adaptive multidimensional strengthening capabilities, which leads to fixed-size reinforcing component designs that cannot adapt to beams of different specifications, requiring on-site cutting and modification. Moreover, the use of unidirectional or bidirectional planar supports cannot form a three-dimensional force system, making it prone to local instability under complex loads and limiting load-bearing capacity. Furthermore, long-term use can lead to loosening of the reinforcing component at the joint due to vibrations of the steel structure, requiring frequent inspection and maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a reinforcing component for a steel structure joint and its installation method, comprising a reinforcing frame, wherein the reinforcing frame has fitting grooves on both outer sides, fitting blocks are embedded in the fitting grooves, a closed clamp is fixedly installed on the outside of the fitting blocks, inner sliding grooves are formed on the upper and lower inner sides of the reinforcing frame, a pushing block is slidably connected inside the inner sliding grooves, upper and lower support frames are fixedly installed at the front end of the pushing block, a middle partition is fixedly installed at the center of the back of the reinforcing frame, a bidirectional screw is rotatably connected inside the middle partition, a rotating head is fixedly installed at the top end of the bidirectional screw, a threaded sleeve is threadedly connected to the outside of the bidirectional screw, and a pushing plate is sleeved on the outside of the threaded sleeve;

[0008] An adjusting screw is rotatably connected inside the upper and lower support frames. An adjusting sleeve is threadedly connected to the outside of the adjusting screw. A first abutting frame is fixedly installed outside the adjusting sleeve. An abutting support rod is hinged inside the first abutting frame. A first rotating shaft is rotatably connected to the outside of the upper and lower support frames. A side reinforcing frame is fixedly installed outside the first rotating shaft.

[0009] Preferably, the outer perimeter of the closed clamp is threaded with reinforcing screws, and the two ends of the reinforcing screws are threaded with tightening nuts. The closed clamp and the reinforcing frame are threadedly connected by the reinforcing screws.

[0010] Preferably, the inner groove is a through groove, and the tail end of the push block that slides inside the inner groove is fixedly connected to the push plate. The upper and lower support frames are fixedly connected to the push plate through the push block, and the upper and lower support frames are also slidably connected to the reinforcing frame.

[0011] Preferably, the push plate is slidably connected to the reinforcing frame, and the two ends of the bidirectional screw have opposite thread directions.

[0012] Preferably, a nitrogen spring is fixedly installed inside the inner slide groove, and an abutment plate is fixedly installed at the front end of the nitrogen spring, the abutment plate abutting against the push block.

[0013] Preferably, the upper and lower support frames are slidably connected to the reinforcing frame, and a rotating screw head is fixedly installed at the front end of the adjusting screw.

[0014] Preferably, the side reinforcement frame is internally rotatably connected to a second rotating shaft, and the other end of the abutting support rod is hinged to the second rotating shaft.

[0015] Preferably, the bottom two sides of the side reinforcement frame are fixedly installed with external fixing plates, and the internal threads of the external fixing plates are penetrated by double-ended bolts.

[0016] Preferably, the outer thread of the double-ended bolt is connected to a bottom reinforcing plate, and the upper surface of the bottom reinforcing plate is provided with anti-slip texture.

[0017] A method for installing a steel structure joint, including the reinforcing components for the steel structure joint as described above, and the specific processing steps are as follows:

[0018] Step 1: The reinforcing frame and the enclosed clamping plate are clamped in the middle of the steel structure beam. The double screw drive mechanism, which consists of a double screw, a rotating head, a threaded sleeve and a push plate, is manually rotated so that the upper and lower support frames abut against the included angle of the joint of the steel structure beam.

[0019] Step 2: Operate the internal screw drive mechanism consisting of the adjusting screw, rotating screw head and adjusting screw sleeve to unfold the side reinforcement frame of the opposing support rod. The side reinforcement frame meets the side angles at different times, and then fits into the other side of the steel structure beam joint to form support.

[0020] Step 3: Use double-headed bolts to install a bottom reinforcement plate at the bottom of the side reinforcement frame, so that the upper and lower plate clamping mechanism composed of the side reinforcement frame, the outer fixing plate and the bottom reinforcement plate can form a stable reinforcement on the other side of the steel structure beam connection.

[0021] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0022] After the reinforcing frame and enclosed clamps are positioned at the midpoint of the steel structure beam, a double-screw drive mechanism, consisting of bidirectional screws, is used to make the upper and lower support frames abut against the included angle of the joint of steel structure beams of different lengths. Then, an internal screw drive mechanism, consisting of adjusting screws, is used to unfold the side reinforcing frame, allowing it to meet different side angles while also fitting against the other side of the steel structure beam joint. This completes the installation and use of the reinforcing component at the steel structure joint. This design gives the reinforcing component at the steel structure joint an adaptive multi-dimensional strengthening capability. The adaptive adjustment of the upper and lower support frames against the joint of beams of different lengths solves the installation error problem caused by poor size adaptability of traditional components. Moreover, the side reinforcing frame can be infinitely unfolded from 0-90°. With the abutment support rod hinged to the second rotating shaft, a three-dimensional support surface with a variable angle is formed. Compared with traditional unidirectional and bidirectional support structures, this can make the stress distribution more uniform, effectively suppress fatigue cracks caused by stress concentration, maintain long-term stable contact, and ensure the stability of the steel structure joint.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] This invention provides, for example Figure 1-8 The present invention relates to a reinforcing component for a steel structure joint and its installation method, comprising a reinforcing frame 1, with fitting grooves 2 on both sides of the outside of the reinforcing frame 1, fitting blocks 3 embedded inside the fitting grooves 2, a closed clamping plate 4 fixedly installed on the outside of the fitting blocks 3, inner sliding grooves 5 on the upper and lower sides of the inside of the reinforcing frame 1, a pushing block 6 slidably connected inside the inner sliding grooves 5, upper and lower support frames 7 fixedly installed at the front end of the pushing block 6, a middle partition plate 8 fixedly installed at the center of the back of the reinforcing frame 1, a bidirectional screw 801 rotatably connected inside the middle partition plate 8, a rotating head 802 fixedly installed at the top end of the bidirectional screw 801, a threaded sleeve 803 threadedly connected to the outside of the bidirectional screw 801, and a pushing plate 804 sleeved on the outside of the threaded sleeve 803.

[0036] The connection sealing is enhanced by the fitting groove 2 and the closed clamp 4, and the inner sliding groove 5 and the push block 6 achieve flexible support and adjustment, thus satisfying the purpose of stable assembly and flexible adjustment.

[0037] An adjusting screw 11 is rotatably connected inside the upper and lower support frames 7. An adjusting screw sleeve 13 is threadedly connected to the outside of the adjusting screw 11. A first abutting frame 14 is fixedly installed on the outside of the adjusting screw sleeve 13. An abutting support rod 15 is hinged inside the first abutting frame 14. A first rotating shaft 16 is rotatably connected to the outside of the upper and lower support frames 7. A side reinforcing frame 17 is fixedly installed on the outside of the first rotating shaft 16.

[0038] Precise adjustment is achieved by adjusting screw 11 and adjusting sleeve 13. The hinged design of the contact support rod 15 enhances dynamic adaptability. The side reinforcement frame 17, together with the first rotating shaft 16, improves the lateral support strength. The whole system forms an adjustable support system, which effectively enhances the deformation resistance and load-bearing stability of the steel structure joints and adapts to diverse installation needs.

[0039] Furthermore, in the above structure, the outer perimeter of the closed clamping plate 4 is threaded with reinforcing screws 401, and the two ends of the reinforcing screws 401 are threaded with tightening nuts 402. The closed clamping plate 4 and the reinforcing frame 1 are threadedly connected by the reinforcing screws 401.

[0040] The detachable threaded connection between the closed clamp plate 4 and the reinforcing frame 1 is achieved by using the reinforcing screw 401 and the tightening nut 402, which strengthens the tensile and shear resistance of the connection node and facilitates on-site assembly and adjustment. At the same time, the layout of the reinforcing screw 401 improves the overall deformation resistance of the structure and ensures that the connection is stable and reliable in the long term.

[0041] Furthermore, in the above structure, the inner slide groove 5 is a through groove, and the tail end of the push block 6 that slides inside the inner slide groove 5 is fixedly connected to the push plate 804. The upper and lower support frames 7 are fixedly connected to the push plate 804 through the push block 6, and the upper and lower support frames 7 are also slidably connected to the reinforcing frame 1.

[0042] Furthermore, in the above structure, the push plate 804 is slidably connected to the reinforcing frame 1, and the two ends of the bidirectional screw 801 have opposite thread directions.

[0043] A wide range of adjustments is achieved through the sliding connection between the inner slide groove 5 of the through groove and the push block 6. The sliding cooperation between the push plate 804 and the reinforcing frame 1 improves the smoothness of movement. The reverse thread of the bidirectional screw 801 enables synchronous bidirectional drive. Overall, the adjustment accuracy and structural stability of the connection are enhanced, adapting to the connection requirements of steel structures of different sizes, and improving installation efficiency and load-bearing reliability.

[0044] Furthermore, in the above structure, a nitrogen spring 9 is fixedly installed inside the inner slide groove 5, and an abutment plate 10 is fixedly installed at the front end of the nitrogen spring 9, which abuts against the push block 6.

[0045] The nitrogen spring 9 and the contact plate 10 provide elastic support, enabling smooth sliding and shock absorption of the push block 6, enhancing the impact resistance and dynamic stability of the steel structure connection, optimizing the smoothness of the adjustment process, extending the service life of the components, and improving the overall structural safety factor.

[0046] Furthermore, in the above structure, the upper and lower support frames 7 are slidably connected to the reinforcing frame 1, and the front end of the adjusting screw 11 is fixedly installed with a rotating screw head 12.

[0047] Furthermore, in the above structure, the side reinforcement frame 17 is internally rotatably connected to a second rotating shaft 18, and the other end of the support rod 15 is hinged to the second rotating shaft 18.

[0048] The upper and lower support frames 7 are slidably connected and rotated screw head 12 for easy adjustment. Combined with the dynamic structure of the side reinforcement frame 17 rotating and the contact support rod 15 hinged, the multi-directional adaptability, deformation resistance and installation flexibility of the steel structure joint are enhanced, effectively improving the overall structural stability and construction efficiency.

[0049] Furthermore, in the above structure, external fixing plates 19 are fixedly installed on both sides of the bottom of the side reinforcement frame 17, and double-ended bolts 20 are threaded through the internal threads of the external fixing plates 19.

[0050] Furthermore, in the above structure, the outer side of the double-ended bolt 20 is threaded with a bottom reinforcing plate 2001, and the upper surface of the bottom reinforcing plate 2001 is provided with anti-slip texture 2002.

[0051] The threaded connection of the external fixing plate 19 and double-headed bolts 20 strengthens the fixing effect of the side reinforcement frame 17. The bottom reinforcement plate 2001, together with the anti-slip texture 2002, enhances the bottom friction, prevents displacement and slippage, and improves the shear resistance and overall stability of the steel structure connection.

[0052] A method for installing a steel structure joint, including the reinforcing components for the steel structure joint as described above, with the specific processing steps as follows:

[0053] Step 1: The reinforcing frame 1 and the closed clamping plate 4 are clamped in the middle of the steel structure beam. The double screw drive mechanism, which consists of a two-way screw 801, a rotating head 802, a threaded sleeve 803 and a push plate 804, is driven so that the upper and lower support frames 7 respectively abut against the included angle of the joint of the steel structure beam.

[0054] Step 2: Operate the inner screw drive mechanism consisting of adjusting screw 11, rotating screw head 12 and adjusting screw sleeve 13 to unfold the side reinforcement frame 17 of the contact support rod 15. The side reinforcement frame 17 satisfies the side angles of different sides and then fits against the other side of the steel structure beam joint to form support.

[0055] Step 3: Use double-headed bolts 20 to install bottom reinforcement plate 2001 at the bottom of side reinforcement frame 17, so that the upper and lower plate clamping mechanism composed of side reinforcement frame 17, outer fixing plate 19 and bottom reinforcement plate 2001 forms a stable reinforcement on the other side of the steel structure beam connection.

[0056] Working principle of this invention:

[0057] Refer to the instruction manual appendix Figure 1 - Figure 8First, remove the reinforcing frame 1 and attach it to the middle of the steel structure beam. Then, use the fitting groove 2 and fitting block 3 to clamp and fix the closed clamp 4 to the steel structure beam from the outside. A detachable threaded connection between the closed clamp 4 and the reinforcing frame 1 is achieved through the reinforcing screw 401 and the tightening nut 402, strengthening the tensile and shear resistance of the connection node and facilitating on-site assembly and adjustment. Next, rotate the rotating head 802 of the bidirectional screw 801, causing the two sets of threaded sleeves 803 on the bidirectional screw 801 to synchronously drive the push plate 804 to slide up and down on the reinforcing frame 1. This is achieved by the bidirectional screw 801 and the rotating head 802... The double-screw drive mechanism, consisting of head 802, threaded sleeve 803, and pusher plate 804, causes the pusher plate 804 to slide up and down via the fixedly connected pusher block 6, respectively abutting against the included angle of the joint of the steel structure beam. Then, according to the current angle of the side of the steel structure joint, the rotating screw head 12 is rotated again to drive the adjusting screw 11 to rotate, allowing the adjusting screw sleeve 13 to slide inside the upper and lower support frames 7, thereby driving the abutment support rod 15 to support the unfolded side reinforcement frame 17. The internal screw drive mechanism, consisting of adjusting screw 11, rotating screw head 12, and adjusting screw sleeve 13, is... The moving mechanism allows the side reinforcement frame 17 to unfold while simultaneously supporting the steel structure side at different angles. It provides support and enables stepless unfolding from 0-90°. After unfolding the side reinforcement frame 17, the double-headed bolts 20 are used to install the bottom reinforcement plate 2001 at the bottom of the side reinforcement frame 17. This creates a clamping mechanism between the side reinforcement frame 17, the outer fixing plate 19, and the bottom reinforcement plate 2001, providing stable reinforcement to the other side of the steel structure beam connection. The bottom reinforcement plate 2001, combined with anti-slip texture 2002, enhances bottom friction, prevents displacement and slippage, and improves the shear strength of the steel structure connection. With improved cutting ability and overall stability, the reinforcing components installed at the steel structure joints possess adaptive multi-dimensional reinforcement capabilities. The synchronous contact of the upper and lower support frames 7 with the joints of beams of different lengths provides adaptive adjustment, solving the installation error problem caused by poor size adaptability of traditional components. Moreover, the side reinforcing frame 17, together with the second rotating shaft 18, hinges the contact support rod 15 to form a three-dimensional support surface with a variable angle. Compared with traditional unidirectional and bidirectional support structures, this can make the stress distribution more uniform, effectively suppress fatigue cracks caused by stress concentration, maintain long-term stable contact, and ensure the stable use of the steel structure joints.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
