Description

Technical Field

[0001] This utility model relates to the technical field of steel truss structure reinforcement nodes, specifically a structural reinforcement node for corrosion cracks at steel truss connections. Background Technology

[0002] Currently, for some existing steel truss structures, due to untimely structural maintenance, the anti-corrosion coating on the outer surface of the steel truss structure peels off, easily leading to rust cracks at the connection points of chords and web members. This severely affects the load-bearing performance and durability of the existing steel truss. How to reinforce the rust cracks at the connection points of steel truss structures to maintain stable load-bearing performance, prevent secondary damage to the cracked structure, and improve the durability of the connection points has become an urgent problem to be solved by those skilled in the art. Therefore, this case was developed through in-depth research into the above-mentioned problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a structural reinforcement node for corrosion cracks at steel truss joints, solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a structural reinforcement node for corrosion cracks at the connection of a steel truss, comprising a reinforcement node set at the connection between the existing steel truss chord and web members, and composed of annular stiffening ribs, connecting stiffening ribs, connecting ring plates and edge sealing plates;

[0005] The inner ring of the annular stiffening rib is welded and fixed to the chord member, and the inner sidewall of the opening is welded and fixed to the web member; the connecting stiffening ribs are symmetrically arranged on both sides of the annular stiffening rib, with one end welded and fixed to the chord member and the other side welded and fixed to the web member; the connecting ring plate consists of four arc-shaped steel plates arranged in a ring and welded and fixed between the annular stiffening rib and the connecting stiffening rib, with one end of the connecting ring plate welded and fixed to the chord member; the sealing plate is welded to the annular stiffening rib, the connecting stiffening rib, and the end of the connecting ring plate, and is welded and fixed to the outer wall of the web member.

[0006] The aforementioned edge banding consists of two identical semi-circular steel plates.

[0007] The welding end face of the aforementioned connecting ring plate and the chord is an irregular arc surface that fits against the outer wall of the chord. Beneficial effects

[0008] This utility model provides a structural reinforcement node for corrosion cracks at steel truss joints. It offers the following advantages: The crack at the connection between the chord and web members of the steel truss is reinforced with annular stiffeners and connecting stiffeners, and then the joint is sealed with connecting ring plates and edge sealing plates. The annular stiffeners and connecting stiffeners not only reinforce the steel truss structure, maintaining stable load-bearing performance, but also minimize welds at the crack, preventing secondary damage to the structure. The design of the connecting ring plates and edge sealing plates prevents the crack from being exposed, avoiding further damage from the outdoor environment (rain, snow, etc.) and improving the durability of the joint. The design of the connecting ring plates further increases the strength and stiffness of the joint, improving its load-bearing performance. Therefore, this reinforcement node not only strengthens the steel truss joint, improving the load-bearing performance of the steel truss structure and ensuring the theoretical feasibility of strong joints and weak members, but also prevents secondary damage to the structure at the crack, significantly improving the durability of the joint.

[0014] 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.

[0015] Example: Refer to the appendix of the instruction manual Figure 1-4As can be seen, this application specifically designs a structural reinforcement node for corrosion cracks at the connection of a steel truss, including a reinforcement node set at the connection between the existing steel truss chord 1 and web member 2, consisting of annular stiffening ribs 3, connecting stiffening ribs 4, connecting ring plates 5, and edge sealing plates 6; wherein the inner ring of the annular stiffening rib 3 is welded and fixed to the chord 1, and the inner sidewall of the opening is welded and fixed to the web member 2; the connecting stiffening ribs 4 are symmetrically arranged on both sides of the annular stiffening rib 3, with one end welded and fixed to the chord 1 and the other side welded and fixed to the web member 2; the connecting ring plate 5 consists of four arc-shaped steel plates arranged in a ring and welded and fixed between the annular stiffening rib 3 and the connecting stiffening rib 4, with one end of the connecting ring plate 5 welded and fixed to the chord 1; the edge sealing plate 6 is welded to the annular stiffening rib 3 and the connecting stiffening rib 4. 4. The end of the connecting ring plate 5 is welded and fixed to the outer wall of the web member 2. The crack at the connection between the steel truss chord member 1 and the web member 2 is reinforced with annular stiffening ribs 3 and connecting stiffening ribs 4. Then, the node structure at this point is sealed with connecting ring plate 5 and sealing plate 6. The annular stiffening ribs 3 and connecting stiffening ribs 4 can not only reinforce the steel truss structure and maintain the stable stress performance of the steel truss, but also have fewer welds at the crack, so as not to cause secondary damage to the structure at the crack. The design of connecting ring plate 5 and sealing plate 6 prevents the crack from being exposed to the outside, preventing the outdoor environment (rain, snow, etc.) from damaging the crack again and improving the durability of the connection node. The design of connecting ring plate 5 also increases the strength and stiffness of the connection node and improves the stress performance of the connection node.

[0016] In practice, as a preferred option, the aforementioned edge sealing plate 6 consists of two semi-circular steel plates with identical structures, making construction more convenient.

[0017] In the specific implementation process, as a preferred setting, the welding end face of the connecting ring plate 5 and the chord 1 is an irregular arc surface that fits against the outer wall of the chord 1, which improves the fit between the end face of the connecting ring plate 5 and the side wall of the chord 1, and enhances the connection stability and sealing quality.

[0018] In summary, this reinforcement node not only strengthens the steel truss connection, improving the load-bearing performance of the steel truss structure and ensuring the theoretical feasibility of strong node weak component, but also avoids secondary damage to the structure at the crack, greatly improving the durability of the node.
