Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated node for a suspended column under an H-shaped steel column. Background Technology

[0002] In multi-story and high-rise steel structure buildings, H-beams and steel columns play a crucial role as the main load-bearing components. The joints connecting these components are not only responsible for transferring bending moments and shear forces between beams and columns, but also have a vital impact on the overall structural performance. However, existing prefabricated joints with suspended columns often have certain problems, such as:

[0003] Application No. 202023193693.0, entitled "An Assembled Node for Under-Suspended Hanging Columns of H-Shaped Steel Columns," includes a steel column, an H-shaped steel beam, T-shaped connectors, L-shaped connectors, and bolts. The T-shaped connector consists of a horizontally arranged upper flange plate connecting plate and a web plate connecting plate perpendicular to the bottom surface of the upper flange plate connecting plate. The upper flange plate connecting plate is bolted to the upper flange plate, and the web plate connecting plate is bolted to the web plate. The L-shaped connector consists of a horizontally arranged lower flange plate connecting plate and a column connecting plate perpendicular to the lower flange plate connecting plate. The lower flange plate connecting plate is bolted to the lower flange plate, and the column connecting plate is bolted to the column flange plate of the steel column. During the assembly of this device, multiple threaded holes must be pre-drilled in the steel column, which reduces the strength of the steel column to some extent, thus failing to meet operational requirements. Therefore, this paper proposes an assembled node for under-suspended hanging columns of H-shaped steel columns to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an H-shaped steel column under-suspension prefabricated node to solve the problem mentioned in the background art that the existing steel column under-suspension prefabricated node must pre-drill multiple threaded holes on the steel column, which to some extent reduces the strength of the steel column.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an H-shaped upper steel column and an H-shaped lower steel column. A connecting flange is fixedly connected to the lower end face of the H-shaped upper steel column, and a mating flange is fixedly connected to the upper end face of the H-shaped lower steel column. A first triangular prism is welded to the right end face of the H-shaped upper steel column, and the first triangular prism is symmetrically arranged about the center of the right end face of the H-shaped upper steel column. A baffle is fixedly connected to the lower end face of the first triangular prism, and the lower end face of the baffle is fixedly connected to the upper right end face of the connecting flange. An assembly plate is welded to the lower end face of the first triangular prism. A second triangular prism is welded to the right end face of the H-shaped lower steel column, and an assembly plate is welded to the upper end face of the second triangular prism.

[0006] The above technical solution avoids the need for pre-drilling holes in the steel columns during assembly, effectively maintaining the original strength of the steel columns. The design of connecting flanges and mating flanges ensures a tight connection between the upper and lower H-shaped steel columns, significantly improving the stability of the joint. The symmetrical layout of the No. 1 and No. 2 triangular columns not only enhances the overall stability of the structure but also achieves uniform stress distribution, extending the service life of the joint. In addition, the design of the No. 1 and No. 2 assembly plates facilitates the installation and disassembly of the joint, greatly improving the convenience and efficiency of construction.

[0007] As a preferred embodiment of this utility model, the left end face of the No. 2 assembly plate is fixedly connected to the right end face of the mating flange.

[0008] By adopting the above technical solution, the connection strength between the upper H-shaped steel column and the lower H-shaped steel column is further enhanced, making the structure of the entire prefabricated node more stable and reliable.

[0009] As a preferred embodiment of this utility model, the connecting flange is threaded with a high-strength bolt, and the connecting flange is fixedly connected to the mating flange by the high-strength bolt.

[0010] By adopting the above technical solution, it is easy to tightly fix the connecting flange and the mating flange with high-strength bolts, which not only improves the firmness of the connection, but also effectively resists the action of external forces and prevents the node from loosening or deforming, thereby ensuring the safety and stability of the assembled node during long-term use.

[0011] As a preferred embodiment of this utility model, an H-shaped steel beam is provided between the first assembly plate and the second assembly plate.

[0012] By adopting the above technical solution, the structural layout of the nodes can be optimized, allowing the nodes to distribute the force more evenly when under stress, reducing stress concentration and thus extending the service life of the nodes.

[0013] As a preferred embodiment of this utility model, threaded holes are provided on the first assembly plate and the second assembly plate, and threaded holes corresponding to those on the H-beam are provided on the first assembly plate and the second assembly plate.

[0014] By adopting the above technical solution, the H-beam is fixedly connected to the No. 1 and No. 2 assembly plates with bolts. This not only simplifies the installation process and improves the assembly efficiency, but also enhances the connection strength between the H-beam and the assembly plates, making the entire node structure more stable and able to withstand greater loads, thereby further improving the node's load-bearing capacity and safety.

[0015] As a preferred embodiment of this utility model, the H-shaped steel beam is fixedly connected to the first assembly plate and the second assembly plate by the high-strength bolts.

[0016] By adopting the above technical solution, the H-beam is tightly connected to the No. 1 and No. 2 assembly plates with high-strength bolts. This not only enhances the overall rigidity of the node and improves its seismic performance, but also effectively prevents relative sliding or deformation between the H-beam and the assembly plates under long-term loads, thereby ensuring the stability and durability of the prefabricated node under various complex working conditions.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated joint of the steel column under suspension column improves the connection strength of the prefabricated joint. By optimizing the connection method between the assembly plate and the H-shaped steel beam, this utility model reduces the complicated steps in the installation process, making the assembly of the entire joint simpler and faster. At the same time, the use of high-strength bolts for fixed connection effectively improves the overall rigidity and seismic performance of the joint, providing a strong guarantee for the safety and stability of the structure.

[0018] 1. When assembling the prefabricated joint of the steel column under suspension, firstly, the upper and lower H-shaped steel columns are initially aligned using connecting flanges and mating flanges. Then, high-strength bolts are used to firmly fix them together, ensuring the strength of the connection. Next, the H-shaped steel beam can be smoothly placed between the first and second assembly plates and fixedly connected to the threaded holes on the first and second assembly plates using bolts. The entire assembly process does not require pre-drilling holes in the steel column, avoiding damage to the original strength of the steel column. At the same time, through reasonable structural design, the joint can distribute the force more evenly when under stress, improving the load-bearing capacity and stability of the joint. During use, the presence of high-strength bolts further enhances the overall rigidity of the joint, improves the seismic performance of the joint, and ensures the safety and durability of the prefabricated joint under various complex working conditions.

[0027] Please see Figures 1-6 The present invention provides a prefabricated joint for a suspended H-shaped steel column, comprising an upper H-shaped steel column 1 and a lower H-shaped steel column 2.

The upper end face of triangular prism 8 is welded with assembly plate 9, which facilitates assembly and avoids the need for pre-drilling holes in the steel column, effectively maintaining the original strength of the steel column. The design of connecting flange 3 and mating flange 4 ensures a tight connection between the upper H-shaped steel column 1 and the lower H-shaped steel column 2, significantly improving the stability of the joint. The symmetrical layout of triangular prism 5 and triangular prism 8 not only enhances the overall stability of the structure but also achieves uniform stress distribution, extending the service life of the joint. In addition, the design of assembly plate 7 and assembly plate 9 facilitates the installation and disassembly of the joint, greatly improving the convenience and efficiency of construction.

[0028] The left end face of the No. 2 assembly plate 9 is fixedly connected to the right end face of the mating flange 4, which further enhances the connection strength between the upper H-shaped steel column 1 and the lower H-shaped steel column 2, making the structure of the entire prefabricated node more stable and reliable.

[0029] The connecting flange 3 is threaded with high-strength bolts 10, and the connecting flange 3 is fixedly connected to the mating flange 4 by the high-strength bolts 10. This makes it easy to tightly fix the connecting flange 3 and the mating flange 4 by the high-strength bolts 10, which not only improves the firmness of the connection, but also effectively resists the action of external forces and prevents the node from loosening or deforming, thereby ensuring the safety and stability of the assembled node during long-term use.

[0030] An H-beam 11 is provided between the No. 1 assembly plate 7 and the No. 2 assembly plate 9, which facilitates the optimization of the structural layout of the node, enabling the node to distribute the force more evenly when under stress, reducing stress concentration, and thus extending the service life of the node.

[0031] Threaded holes are provided on the No. 1 assembly plate 7 and the No. 2 assembly plate 9, and threaded holes corresponding to those on the H-beam 11 are provided on the No. 1 assembly plate 7 and the No. 2 assembly plate 9. The H-beam 11 is fixedly connected to the No. 1 assembly plate 7 and the No. 2 assembly plate 9 by bolts.

[0032] H-beam 11 is fixedly connected to No. 1 assembly plate 7 and No. 2 assembly plate 9 by high-strength bolts 10. The high-strength bolts 10 tightly connect H-beam 11 to No. 1 assembly plate 7 and No. 2 assembly plate 9, which not only enhances the overall rigidity of the node and improves the seismic performance of the node, but also effectively prevents the relative sliding or deformation between H-beam 11 and the assembly plate under long-term load, thereby ensuring the stability and durability of the prefabricated node under various complex working conditions.

[0033] Working Principle: When assembling the prefabricated joint of the steel column under suspension, the H-shaped upper steel column 1 and H-shaped lower steel column 2 are first initially aligned using connecting flange 3 and mating flange 4. Then, high-strength bolts 10 are used to firmly fix them together, ensuring the strength of the connection. Next, the H-shaped steel beam 11 can be smoothly placed between the first assembly plate 7 and the second assembly plate 9, and fixedly connected to the threaded holes on the first assembly plate 7 and the second assembly plate 9 with bolts. The entire assembly process does not require pre-drilling holes in the steel column, avoiding damage to the original strength of the steel column. At the same time, through reasonable structural design, the joint can distribute the force more evenly when under stress, improving the load-bearing capacity and stability of the joint. During use, the presence of high-strength bolts 10 further enhances the overall rigidity of the joint, improves the seismic performance of the joint, and ensures the safety and durability of the prefabricated joint under various complex working conditions.
