Description

Technical Field

[0001] This utility model relates to the field of steel structure reinforcement structure, specifically a side-mounted reinforcement unit and its circumferential self-reinforcing steel structure beam-column joint. Background Technology

[0002] Steel structure buildings are lightweight, quick to construct, reusable, and align with current green building development principles. However, problems in the joint design of steel structure buildings can severely impact their quality. The primary material used in steel structures is steel, which has high strength, effectively ensuring the building's structural integrity. Simultaneously, steel structure construction is efficient, fast, and cost-effective, ensuring economic benefits for businesses. As an irreplaceable mainstay in the construction industry, steel structure buildings are becoming increasingly widespread and valued. Beam-column joints are a crucial component of steel structures; their comprehensive consideration during the design phase directly impacts the structure's integrity and reliability, as well as the quality of manufacturing and installation, project progress, and overall construction cycle and cost.

[0003] Under normal loads, steel structures exhibit excellent load-bearing capacity. However, under special loads such as earthquakes, steel requires high ductility. When subjected to triaxial tension, steel cannot undergo lateral contraction or shear slip deformation, leading to brittle failure without apparent cause. Particularly at the welded joints of beam-column flanges, the intersecting structure of beam-column joints, due to its cross-sectional nature, results in a lack of standardized reinforcement methods and emergency reinforcement measures capable of multi-faceted reinforcement of the lateral aspects of steel structure joints when damage or rapid reinforcement is needed. Utility Model Content

[0004] The purpose of this invention is to provide a side-mounted reinforcing unit and its constituent circumferential self-reinforcing steel structure beam-column joint, which can effectively and rapidly reinforce the top beam-column joint in the steel structure from all directions, thereby improving stability and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A side-mounted reinforcement unit includes an upper enclosure plate, a lower enclosure plate, and two connecting rods. Both the upper and lower enclosure plates are L-shaped plates, arranged horizontally from top to bottom. The two connecting rods are arranged vertically side by side between the upper and lower enclosure plates. The upper end of each connecting rod passes through the upper enclosure plate, and the lower end of each connecting rod is detachably connected to the lower enclosure plate. When the side-mounted reinforcement unit is connected to a steel structure beam-column joint, the inner walls of both the upper and lower enclosure plates are tightly fitted against one corner of the steel column in the steel structure beam-column joint. Each end of the upper enclosure plate is connected to the upper wing of the H-shaped steel beam in the adjacent steel structure beam-column joint, and each end of the lower enclosure plate is engaged with the lower wing of the H-shaped steel beam in the adjacent steel structure beam-column joint.

[0007] A circumferentially self-strengthening steel structure beam-column joint, utilizing the aforementioned lateral reinforcement unit, comprises a steel structure beam-column joint and four lateral reinforcement units. The steel structure beam-column joint includes a steel column and four H-shaped steel beams. The steel column is a square column, and the four H-shaped steel beams are horizontally positioned on the four outer sides of the steel column. A lateral reinforcement unit is positioned at each of the four corners of the steel column. Each lateral reinforcement unit includes an upper enclosure plate, a lower enclosure plate, and two connecting rods. The upper and lower enclosure plates are both L-shaped plates. The upper and lower enclosure plates are horizontally arranged from top to bottom. Two connecting rods are vertically arranged side by side between the upper and lower enclosure plates. The upper end of each connecting rod passes through the upper enclosure plate, and the lower end of each connecting rod is detachably connected to the lower enclosure plate. The inner walls of the upper and lower enclosure plates are both tightly attached to one end corner of the steel column. The two ends of the upper enclosure plate are respectively connected to the upper wings of the two H-shaped steel beams adjacent to the upper enclosure plate. The two ends of the lower enclosure plate are respectively engaged with the lower wings of the two H-shaped steel beams adjacent to the lower enclosure plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention enables comprehensive, multi-position reinforcement, enhancing the strength of steel structure beam-column joints and improving their compressive and bending resistance. The cooperation between the upper and lower enclosing plates and two connecting rods ensures four-sided enclosure and clamping reinforcement around the steel structure beam-column joint, improving the balanced stability of the reinforced joint. The H-shaped steel beam in the joint is clamped and fixed by the upper and lower enclosing plates, achieving multi-point reinforcement. Each connecting rod connects the upper and lower enclosing plates, forming a multi-point combined surface reinforcement feature. Reinforcement is carried out using the empty space between the steel beam and column, improving the rationality of the reinforcement layout. The assembly method is convenient and easy to operate, facilitating installation, disassembly, and subsequent repeated installation and disassembly, making it more suitable for rapid or emergency construction conditions.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] As mentioned in the background section of this application, research has found that existing steel structure beam-column joints lack reinforcement structures, have weak stability, and are prone to deformation and damage, thus exhibiting certain defects.

[0022] To address the aforementioned deficiencies, this application discloses a side-mounted reinforcing unit and its constituent circumferentially self-reinforcing steel structure beam-column joints, which can effectively reinforce the beam-column joints of steel structures, thereby improving stability.

[0023] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This embodiment includes an upper enclosure plate 1, a lower enclosure plate 2, and two connecting rods 3. Both the upper enclosure plate 1 and the lower enclosure plate 2 are L-shaped plates, arranged horizontally from top to bottom. The two connecting rods 3 are arranged vertically side by side between the upper enclosure plate 1 and the lower enclosure plate 2. The upper end of each connecting rod 3 passes through the upper enclosure plate 1, and the lower end of each connecting rod 3 is detachably connected to the lower enclosure plate 2. When the side-mounted reinforcement unit is connected to the steel structure beam-column node 20, the inner walls of the upper enclosure plate 1 and the lower enclosure plate 2 are both tightly attached to one end corner of the steel column 21 in the steel structure beam-column node 20. Each end of the upper enclosure plate 1 is connected to the upper wing 22-1 of the H-shaped steel beam 22 in the adjacent steel structure beam-column node 20, and each end of the lower enclosure plate 2 is engaged with the lower wing 22-2 of the H-shaped steel beam 22 in the adjacent steel structure beam-column node 20.

[0024] Furthermore, the end of the upper enclosure plate 1 is snapped into connection with the upper wing 22-1 of the H-beam 22 in the steel beam-column node 20, while the end of the lower enclosure plate 2 is snapped into connection with the lower wing 22-2 of the H-beam 22 in the steel beam-column node 20. The upper enclosure plate 1 and the lower enclosure plate 2 are effectively connected by the connecting rod 3, thereby ensuring the improved balance and stability of the steel beam-column node 20 after reinforcement and enhancing the compressive and bending resistance of the steel beam-column node 20.

[0025] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The upper enclosure plate 1 includes a first main body 1-1. The two ends of the first main body 1-1 are respectively machined with first half grooves 1-1-1. The bottom of each first half groove 1-1-1 is closely attached to the lower side of the upper wing 22-1 of the nearby H-shaped steel beam 22. The inner end of each first half groove 1-1-1 is closely attached to the outer wall of the upper wing 22-1 of the nearby H-shaped steel beam 22. An upper connecting plate 4 is provided on the upper enclosure plate 1. The bottom surface of the upper connecting plate 4 is closely attached to the top surface of the upper enclosure plate 1 and the top surface of the H-shaped steel beam 22. The upper connecting plate 4 is detachably connected to the upper enclosure plate 1 and the H-shaped steel beam 22.

[0026] Combination Figures 1 to 4 The upper enclosure plate 1 has two forms. The first form is the basic form, in which first half-grooves 1-1-1 are machined at both ends of the first main body 1-1. The first half-grooves 1-1-1 are attached to the upper wing 22-1 of the H-shaped steel beam 22 through the first half-grooves 1-1-1. The lower enclosure plate 2 is used to snap the lower wing 22-2 of the H-shaped steel beam 22. The upper enclosure plate 1 and the lower enclosure plate 2 are connected and fixed around the steel structure beam-column node 20 by the connecting rod 3. The second form is that an upper connecting plate 4 is set above the upper enclosure plate 1. The bottom surface of the upper connecting plate 4 is attached to the top surface of the upper enclosure plate 1 and the top surface of the H-shaped steel beam 22. Similarly, the lower enclosure plate 2 snaps the lower wing 22-2 of the H-shaped steel beam 22. The upper enclosure plate 1 and the lower enclosure plate 2 are connected and fixed around the steel structure beam-column node 20 by the connecting rod 3.

[0027] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The upper enclosure plate 1 is machined with a first connecting hole 7 that can be detachably connected to the upper connecting plate 4. The first connecting hole 7 is a screw hole or other type of connecting hole, which serves a connecting function. Its specific machining position and number can be machined on the upper enclosure plate 1 according to the reinforcement design requirements.

[0028] Furthermore, the upper connecting plate 4 comes in two forms, combined with... Figure 3 As shown, in the first form, the upper connecting plate 4 is an L-shaped plate. When the first half-groove 1-1-1 on the first main body 1-1 is in contact with the lower side of the upper wing 22-1 of the H-shaped steel beam 22, the upper connecting plate 4 is in contact with the upper side of the upper wing 22-1 and the upper side of the first main body 1-1. At the same time, the end of the upper connecting plate 4 is flush with the end of the first half-groove 1-1-1, so that the upper wing 22-1 can be snapped in place. The lower enclosure plate 2 snaps in place the lower wing 22-2 of the H-shaped steel beam 22. The upper enclosure plate 1 and the lower enclosure plate 2 are connected and fixed by the connecting rod 3.

[0029] Combination Figure 4As shown, the second form is that the upper connecting plate 4 includes two horizontal plates. When the first half groove 1-1-1 on the first main body 1-1 is in contact with the lower side of the upper wing 22-1 of the H-shaped steel beam 22, the two horizontal plates are respectively attached to the upper side of the upper wing 22-1 and the upper side of the first main body 1-1. The working principle of the upper connecting plate 4 is the same, but the form of appearance is different.

[0030] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. The lower enclosure plate 2 includes a second main body 2-1 and a bottom plate 2-2. Both the second main body 2-1 and the bottom plate 2-2 are L-shaped plates. The bottom plate 2-2 is located directly below the second main body 2-1. The two ends of the second main body 2-1 are respectively machined with second half grooves 2-1-1. The bottom of each second half groove 2-1-1 is close to the upper side of the lower wing 22-2 of the nearby H-shaped steel beam 22. The inner end of each second half groove 2-1-1 is close to the outer wall of the lower wing 22-2 of the nearby H-shaped steel beam 22. The upper side of the bottom plate 2-2 is close to the bottom side of the second main body 2-1 and the lower side of the lower wing 22-2 of the two H-shaped steel beams 22.

[0031] Furthermore, the two ends of the second main body 2-1 are respectively machined with second half grooves 2-1-1. The second main body 2-1 is closely attached to the upper side of the lower wing 22-2 of the H-shaped steel beam 22 through the second half grooves 2-1-1 to avoid unstable connection. The bottom side of the second main body 2-1 and the bottom side of the lower wing 22-2 of the two H-shaped steel beams 22 are closely attached by the base plate 2-2, and the second main body 2-1 and the base plate 2-2 are connected and fixed together by the connecting rod 3. At the same time, a second U-shaped notch 6 can be formed between the second half groove 2-1-1 and the base plate 2-2. The second U-shaped notch 6 can stably clamp the lower wing 22-2, thereby ensuring that the side-mounted reinforcement unit can effectively reinforce the steel structure beam-column node 20.

[0032] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3 or 4. A first U-shaped notch 5 is processed at each end of the upper enclosure plate 1, and the opening end of each first U-shaped notch 5 is set towards the upper wing 22-1 of the nearby H-shaped steel beam 22; a second U-shaped notch 6 is processed at each end of the lower enclosure plate 2, and the opening end of each second U-shaped notch 6 is set towards the lower wing 22-2 of the nearby H-shaped steel beam 22.

[0033] Furthermore, when the upper connecting plate 4 in the upper enclosure plate 1 is attached to the upper side of the first main body 1-1, a first U-shaped notch 5 can be formed between the first semi-groove 1-1-1 and the upper connecting plate 4. This allows the upper wing 22-1 of the H-beam 22 to be clamped by the first U-shaped notch 5 when the upper and lower sides of the upper wing 22-1 of the first main body 1-1 and the upper connecting plate 4 are attached together. Similarly, the second main body in the lower enclosure plate 2... During the connection process between 2-1 and the base plate 2-2, a second U-shaped notch 6 can be formed between the second half groove 2-1-1 on the second main body 2-1 and the base plate 2-2. The lower wing 22-2 of the H-shaped steel beam 22 is clamped by the second U-shaped notch 6. At the same time, the upper enclosure plate 1 and the lower enclosure plate 2 are fixedly connected by the connecting rod 3. Thus, when supporting the steel structure beam-column node 20, the balanced stability performance of the steel structure beam-column node 20 can be improved.

[0034] Specific Implementation Method Six: Combination Figures 1 to 9 This embodiment describes a steel structure beam-column node 20 and four lateral reinforcement units. The steel structure beam-column node 20 includes a steel column 21 and four H-shaped steel beams 22. The steel column 21 is a square column, and the four H-shaped steel beams 22 are horizontally arranged on the four outer sides of the steel column 21. A lateral reinforcement unit is respectively arranged at each of the four corners of the steel column 21. Each lateral reinforcement unit includes an upper enclosure plate 1, a lower enclosure plate 2, and two connecting rods 3. The upper enclosure plate 1 and the lower enclosure plate 2 are both L-shaped plates, and the upper enclosure plate 1 and the lower enclosure plate 2 extend from top to bottom. The upper and lower enclosure plates 21 are arranged horizontally in sequence. Two connecting rods 3 are arranged vertically side by side between the upper enclosure plate 1 and the lower enclosure plate 2. The upper end of each connecting rod 3 passes through the upper enclosure plate 1, and the lower end of each connecting rod 3 is detachably connected to the lower enclosure plate 2. The inner walls of the upper enclosure plate 1 and the lower enclosure plate 2 are both close to one corner of the steel column 21. The two ends of the upper enclosure plate 1 are respectively connected to the upper wings 22-1 of the two H-shaped steel beams 22 that are close to the upper enclosure plate 1. The two ends of the lower enclosure plate 2 are respectively engaged with the lower wings 22-2 of the two H-shaped steel beams 22 that are close to the lower enclosure plate 2.

[0035] Furthermore, the side-mounted reinforcement unit can be installed around the steel structure beam-column node 20 through the cooperation of the upper enclosure plate 1, the lower enclosure plate 2, and the two connecting rods 3. The upper enclosure plate 1 and the lower enclosure plate 2 are used to clamp the upper wing 22-1 and the lower wing 22-2 of the four H-shaped steel beams 22, thereby enhancing the stability of the steel structure beam-column node 20. At the same time, the upper enclosure plate 1 and the lower enclosure plate 2 can also be disassembled. Therefore, the side-mounted reinforcement unit can achieve a rapid and emergency installation process according to specific reinforcement requirements when used with the steel structure beam-column node 20. The installation process causes little secondary damage to the steel structure beam-column node 20, and it can be repeatedly disassembled for easy local adjustment.

[0036] Specific implementation method seven: This implementation method is a further limitation of specific implementation method six. Each connecting rod 3 is a screw rod, and a first nut 16 is provided at the lower end of each screw rod. After the lower end of each connecting rod 3 passes through the lower enclosure plate 2, it is connected to its corresponding first nut 16. The first nut 16 is close to the bottom surface of the lower enclosure plate 2.

[0037] Furthermore, when the upper enclosure plate 1 and the lower enclosure plate 2 are snapped into the upper wing 22-1 and lower wing 22-2 of the H-shaped steel beam 22, the upper enclosure plate 1 and the lower enclosure plate 2 are fixed by the connecting rod 3. Since the connecting rod 3 is a screw, the lower end of the screw should be fitted with a first nut 16. When the connecting rod 3 passes through the lower enclosure plate 2, the first nut 16 is fixed, thereby ensuring that the bottom plate 2-2 in the lower enclosure plate 2 is not easy to fall off when it is against the lower side of the lower wing 22-2 of the H-shaped steel beam 22. This makes it easy to install, disassemble, and subsequently repeat the installation and disassembly of the side-mounted reinforcement unit on the steel structure beam-column node 20.

[0038] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six or Seven. The bottoms of two lower enclosure plates 2 on the same H-shaped steel beam 22 are connected by a support plate 17. Each connecting rod 3 is a screw rod, and a second nut 18 is provided at the lower end of each screw rod. The lower end of each screw rod passes through the lower enclosure plate 2 and the support plate 17 in sequence and is connected to its corresponding second nut 18. The second nut 18 is close to the bottom surface of the support plate 17.

[0039] Furthermore, the lower enclosure plate 2 is an L-shaped plate. When the two lower enclosure plates 2 surround the lower wing 22-2 of the H-shaped steel beam 22, the adjacent plates between the two lower enclosure plates 2 can be flush. At the same time, the support plate 17 is a horizontal support plate. The width of the support plate 17 is the same as the width of the lower enclosure plate 2. The upper side of the support plate 17 is in contact with the two lower enclosure plates 2 and the lower wing 22-2. One end of the support plate 17 is in contact with one side of the steel column 21. Meanwhile, the lower end of the connecting rod 3 passes through the lower enclosure plate 2 and the support plate 17 respectively and is fixed by the second nut 18, thereby ensuring that the side-mounted reinforcement unit can effectively reinforce the steel structure beam-column node 20.

[0040] The operation process of this embodiment is as follows: The upper enclosure plate 1 and the lower enclosure plate 2 are installed on the steel column 21 near the four corners of the four H-shaped steel beams 22. The upper connecting plate 4 on the upper enclosure plate 1 is placed on the upper side of the upper wing 22-1 of the H-shaped steel beam 22. The bottom of each first half groove 1-1-1 on the first main plate 1-1 is attached to the lower side of the upper wing 22-1 of the H-shaped steel beam 22. The upper connecting plate 4 and the first main plate 1-1 are connected by the upper end of each connecting rod 3. At the same time, the second main plate 2-1 on the lower enclosure plate 2 is attached to the upper side of the lower wing 22-2 of the H-shaped steel beam 22. The upper side of the bottom plate 2-2 is attached to the second main plate 2-1 and the lower wing 22-2 of the H-shaped steel beam 22. On the lower side, the lower end of each connecting rod 3 passes through the second main body 2-1 and the bottom plate 2-2 in sequence, and is fixed by screwing on the first nut 16; when the support plate 17 appears, the upper enclosure plate 1 and the lower enclosure plate 2 are also installed on the upper wing 22-1 and the lower wing 22-2 of the four H-shaped steel beams 22. At the same time, the support plate 17 is installed on the lower side of the lower enclosure plate 2. The upper side of the support plate 17 is attached to the lower side of the lower enclosure plate 2 and the lower wing 22-2. One end of the support plate 17 is attached to the side of the steel column 21. The upper end of the connecting rod 3 is installed on the upper enclosure plate 1. The lower end of the connecting rod 3 passes through the lower enclosure plate 2 and the support plate 17 in sequence. The support plate 17 is fixed on the lower enclosure plate 2 by screwing on the second nut 18.

[0041] Specific Implementation Method Nine: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, Seven, or Eight. In this implementation method, the lower enclosing plate 2 is an integral plate or a self-assembled plate, combined with... Figure 5 As shown, when the lower enclosure plate 2 is a self-assembly plate, it includes an upper plate and a lower plate. The lower plate is a component structure that forms the top of either of the two second U-shaped notches 6. One second U-shaped notch 6 is a fixed structure, while the other second U-shaped notch 6 is formed later. This facilitates the corresponding assembly when there is insufficient assembly space outside the steel structure beam-column joint. After one second U-shaped notch 6 is connected to a lower wing 22-2, the other lower wing 22-2 is assembled with the lower plate through the other end of the upper plate to form another second U-shaped notch 6 structure, which is used to clamp the lower wing 22-2. Finally, it is connected by bolts, which facilitates the multi-position clamping process in the effective assembly space and helps to improve the rapid assembly performance.

[0042] In the specific processing and manufacturing of the side-mounted reinforcement unit of this utility model, the upper enclosure plate 1 and the upper end of the connecting rod 3 are fixedly connected to form an integrated structure, which facilitates the reduction of assembly and alignment processes.

[0043] The working principle of this utility model is as follows: Different working principles are selected according to the working conditions and reinforcement design requirements:

[0044] Working Principle 1: Pre-assembly followed by on-site installation: Connecting rod 3 is fixedly connected to upper enclosure plate 1. After the lower end of connecting rod 3 passes through lower enclosure plate 2, the relative position between connecting rod 3 and lower enclosure plate 2 is fixed by first nut 16 or second nut 18, forming a side-mounted reinforcement unit. Other side-mounted reinforcement units are assembled in the same way. Then, the assembled side-mounted reinforcement units are installed into the steel structure beam-column node 20, ensuring that upper enclosure plate 1 and lower enclosure plate 2 are respectively attached to the corresponding positions on the four outer sides of the steel column 21. The two ends of each upper enclosure plate 1 are respectively connected to the upper wing 22-1 of its corresponding H-shaped steel beam 22, and the two ends of each lower enclosure plate 2 are respectively connected to the lower wing 22-2 of its corresponding H-shaped steel beam 22.

[0045] Working Principle 2: On-site Assembly and Installation: The upper enclosure plate 1 with connecting rod 3 is attached to the corresponding position in the steel structure beam-column node 20. The two ends of the upper enclosure plate 1 are pre-connected to the upper wing 22-1 of the corresponding H-shaped steel beam 22. The arrangement position of the lower enclosure plate 2 is arranged according to the vertical distance between the upper wing 22-1 and the lower wing 22-2 in the steel structure beam-column node 20. Then, the upper enclosure plate 1 with connecting rod 3 is removed, and the lower end of the connecting rod 3 is passed through the lower enclosure plate 2 and fixed. Then, the resulting side-mounted reinforcement unit is installed in the corresponding position in the steel structure beam-column node 20 for final connection. Other side-mounted reinforcement units can be assembled and installed on-site in this manner.
