Description

Technical Field

[0001] This utility model relates to the field of steel structure connection, specifically a corrosion-resistant steel structure node. Background Technology

[0002] As the key to connecting various components, steel structure nodes are crucial to structural safety. They are responsible for transferring loads, maintaining stability, and ensuring the integrity of the structure. Nodes come in various forms, including welding and bolted connections. When designing, the stress state, load, ease of construction, and maintenance and inspection must be considered. Special nodes, such as stiffened plates and intersecting types, can meet specific requirements. The patent application CN211200711U, titled "An Anti-corrosion Node for Underground Steel Structures," describes a technical solution that uses a non-welding method to connect steel beams and columns and applies a corrosion-resistant buffer layer to slow down the corrosion reaction rate. Specifically, this solution uses bolts to fix four I-beams on the outside of the column as connection nodes for the steel structure. However, in actual installation, this design has a problem: when operators install the bolts, they need to precisely align the ends of the I-beams with the column surface and the predetermined installation position. This step requires providing stable support to the ends of the I-beams to ensure the smooth progress and accurate positioning of subsequent bolt installation. Since the original design did not have a built-in effective support structure, additional support equipment must be used to complete this operation, which undoubtedly increases the complexity and inconvenience of steel structure installation and connection. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a corrosion-resistant steel structure node to solve the technical problem that traditional steel structure connection technology does not have a clearly defined support structure for the I-beam, thus reducing the convenience and efficiency of bolt installation between the I-beam and the column.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant steel structure node, including a column and an I-beam. Mounting ears are welded and fixed at the four outer corners of the column. A base plate is welded and fixed below adjacent mounting ears. A cavity is formed between adjacent mounting ears and the corresponding base plate below. The cavity has an open structure above it. The inner side of the cavity is bolted to the I-beam through a connecting component. The base plate supports the bottom of the connecting component.

[0005] By adopting the above technical solution, the mounting ears welded and fixed at the four corners of the outer side of the column and the base plate welded below the adjacent mounting ears form a stable cavity structure, which not only enhances the overall structural strength of the node, but also provides reliable installation space and support for the connecting components inside the cavity. At the same time, the open structure of the cavity facilitates the installation and adjustment of the connecting components, making the entire node assembly process more convenient and efficient.

[0006] Furthermore, the cavity has an open structure and is adapted to the connecting assembly, and the mounting ear has a rectangular plate structure.

[0007] By adopting the above technical solution, it is ensured that the connecting components can be accurately installed into the cavity, improving the accuracy and efficiency of assembly. At the same time, the mounting ears are rectangular plate-shaped structures, which not only increase the welding contact area with the column and improve the welding strength, but also provide stable bolt connection points for the side plates.

[0008] Furthermore, the connection assembly includes a mounting motherboard, with side plates fixedly disposed on both sides of the mounting motherboard, and the side plates being connected to corresponding mounting lug bolts by multiple bolts.

[0009] By adopting the above technical solution, the connecting components have strong integrity and rigidity, which can effectively transfer and distribute loads. At the same time, the side plate is connected to the corresponding mounting lug bolts by multiple bolts, which realizes the stable fixation of the node in the horizontal direction and prevents the node from lateral displacement when under stress.

[0010] Furthermore, the mounting motherboard is installed with the column bolts via multiple bolts.

[0011] By adopting the above technical solution, a tight connection between the connecting components and the column is ensured, improving the overall stability and load-bearing capacity of the node. At the same time, this bolt connection method facilitates quick installation and disassembly on site, providing convenience for the maintenance and replacement of the node.

[0012] Furthermore, two sets of first connecting plates and second connecting plates are fixedly installed on the side of the mounting motherboard near the I-beam.

[0013] By adopting the above technical solution, multi-point connection between the connecting component and the I-beam is realized, which improves the stability and reliability of the connection. At the same time, the first connecting plate is attached to the upper and lower surfaces of the I-beam and connected by multiple bolts to ensure the stable fixation of the node in the vertical direction.

[0014] Furthermore, the two sets of first connecting plates are attached to the upper and lower surfaces of the I-beam and are bolted to the I-beam with multiple bolts. The two sets of second connecting plates are located on both sides of the web of the I-beam and are bolted to the web of the I-beam with multiple bolts.

[0015] By adopting the above technical solution, the stability and load-bearing capacity of the node in the vertical direction are ensured. At the same time, this close-fitting connection also reduces stress concentration when the node is under stress, and improves the fatigue life of the node.

[0016] Furthermore, the outer side of the connecting component is uniformly coated with an anti-corrosion coating and a waterproof layer.

[0017] By adopting the above technical solutions, effective anti-corrosion protection is provided for the nodes, extending their service life. At the same time, the presence of the waterproof layer also prevents moisture from penetrating into the interior of the nodes, avoiding rust and corrosion of the internal metal components.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model provides a reliable installation space and support for the connection between the I-beam and the column by installing ears, a base plate, and connecting components. This allows the connecting components to be accurately positioned and installed in the cavity without the need for additional support structures to fix the I-beam, thereby simplifying the assembly process, improving installation efficiency, reducing the steps of supporting the I-beam in traditional operations, and avoiding installation deviations or unstable connections caused by improper support. This improves the ease of connection and installation between the I-beam and the column, and reduces construction difficulty and cost.

[0020] 2. This utility model, by setting a first connecting plate and a second connecting plate, ensures the stability and load-bearing capacity of the node in the vertical direction by tightly fitting the first connecting plate to the upper and lower surfaces of the I-beam and connecting it with bolts. It can effectively transfer and disperse the vertical load from the I-beam, making the entire node more uniformly stressed and improving the overall stiffness and strength of the node. At the same time, the second connecting plate is located on both sides of the web of the I-beam and is connected to the web with bolts, enhancing the connection strength of the node in the horizontal direction. It can effectively limit the displacement and rotation of the I-beam in the horizontal direction, improving the overall stability and seismic performance of the node. Therefore, the combined effect of the first connecting plate and the second connecting plate enables the anti-corrosion steel structure node to maintain stable performance when subjected to various complex loads, improving the reliability and durability of the node.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] A type of corrosion-resistant steel structure node, such as Figures 1-4 As shown, the structure includes a column 1 and an I-beam 2. Mounting ears 3 are welded and fixed at the four outer corners of the column 1. A base plate 4 is welded and fixed below each adjacent mounting ear 3. A cavity 5 is formed between the adjacent mounting ears 3 and the corresponding base plate 4. The cavity 5 has an open structure at the top. The inner side of the cavity 5 is bolted to the I-beam 2 via a connecting component 6. The base plate 4 supports the bottom of the connecting component 6. The mounting ears 3 welded and fixed at the four outer corners of the column 1 and the base plate 4 welded below the adjacent mounting ears 3 form a stable cavity 5 structure. This not only enhances the overall structural strength of the node but also provides reliable installation space and support for the connecting component 6 inside the cavity 5. Furthermore, the open structure of the cavity 5 facilitates the installation and adjustment of the connecting component 6, making the assembly process of the entire node more convenient and efficient. In addition, the supporting effect of the base plate 4 on the bottom of the connecting component 6 further improves the stability and load-bearing capacity of the node.

[0029] See Figure 1 , Figure 2 The cavity 5 has an open structure and is adapted to the connecting component 6. The mounting ear 3 has a rectangular plate structure, which ensures that the connecting component 6 can be accurately installed into the cavity 5, improving the accuracy and efficiency of assembly. At the same time, the rectangular plate structure of the mounting ear 3 not only increases the welding contact area with the column 1 and improves the welding strength, but also provides a stable bolt connection point for the side plate 602, enhancing the connection stability and reliability of the entire node, so that the node can maintain stable performance when subjected to large loads.

[0030] Example 2:

[0031] See Figure 3 , Figure 4 The connecting component 6 includes a mounting main board 601, with side plates 602 fixedly installed on both sides of the mounting main board 601. The side plates 602 are connected to the corresponding mounting ears 3 by multiple bolts, giving the connecting component 6 strong integrity and rigidity, and effectively transferring and distributing loads. At the same time, the side plates 602 are connected to the corresponding mounting ears 3 by multiple bolts, achieving stable fixation of the node in the horizontal direction and preventing lateral displacement of the node under stress. This connection method not only improves the connection strength of the node, but also facilitates on-site installation and adjustment, reducing construction difficulty.

[0032] See Figure 1 , Figure 2 , Figure 3 The mainboard 601 is installed with multiple bolts to the column 1, ensuring a tight connection between the connecting component 6 and the column 1, improving the overall stability and load-bearing capacity of the node. At the same time, this bolted connection method facilitates quick installation and disassembly on site, providing convenience for the maintenance and replacement of the node. In addition, the use of multiple bolts also increases the redundancy of the connection, so even if individual bolts become loose or damaged, it will not seriously affect the stability of the entire node.

[0033] See Figure 3 , Figure 4 Two sets of first connecting plates 603 and second connecting plates 604 are fixedly installed on the side of the mounting motherboard 601 near the H-beam 2, realizing multi-point connection between the connecting component 6 and the H-beam 2, improving the stability and reliability of the connection. At the same time, the first connecting plate 603 is in contact with the upper and lower surfaces of the H-beam 2 and is connected by multiple bolts to ensure the stable fixation of the node in the vertical direction. The second connecting plate 604 is located on both sides of the web of the H-beam 2 and is connected by multiple bolts, further enhancing the connection strength of the node in the horizontal direction. This multi-point connection method enables the node to better withstand various complex loads.

[0034] See Figure 3 , Figure 4 Two sets of first connecting plates 603 are fitted to the upper and lower surfaces of the I-beam 2 and bolted to the I-beam 2 with multiple bolts. Two sets of second connecting plates 604 are located on both sides of the web of the I-beam 2 and bolted to the web of the I-beam 2 with multiple bolts. This ensures the stability and load-bearing capacity of the node in the vertical direction. At the same time, this fitted connection also reduces the stress concentration phenomenon of the node under stress and improves the fatigue life of the node. In addition, the two sets of second connecting plates 604 are located on both sides of the web of the I-beam 2 and connected by multiple bolts, which not only enhances the connection strength of the node in the horizontal direction, but also enables the node to better adapt to the deformation and displacement of the I-beam 2, improving the overall coordination and seismic performance of the node.

[0035] See Figure 1 , Figure 2 The outer side of the connecting component 6 is uniformly coated with an anti-corrosion coating and a waterproof layer, which provides effective anti-corrosion protection for the node and extends its service life. At the same time, the presence of the waterproof layer also prevents moisture from penetrating into the node, avoiding rust and corrosion of the internal metal components. This dual protection of anti-corrosion and waterproofing enables the node to maintain stable performance under harsh environmental conditions, improving the reliability and durability of the node.

[0036] The implementation principle of this utility model is as follows: Mounting ears 3 are welded to the four corners of the outer side of the column 1, and a base plate 4 is welded between adjacent mounting ears 3 to form a cavity 5. This cavity 5 provides installation space for the connecting component 6 and is stably supported by the base plate 4 below it. Then, it is tightly connected to the column 1, mounting ears 3 and I-beam 2 by bolts, which ensures the stability and rigidity of the entire node. In particular, the first connecting plate 603 is bolted to the upper and lower surfaces of the I-beam 2, and the second connecting plate 604 is connected to the web of the I-beam 2. This multi-point connection method further enhances the stability of the node. In addition, the anti-corrosion coating and waterproof layer coated on the outer side of the connecting component 6 effectively resist corrosion and humid environment, and extend the service life of the node.
