Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and more specifically, to a steel structure node connector. Background Art

[0002] Steel structure refers to a load-bearing structure formed by processing steel plates and sections into various shaped steel members and then connecting and fixing the steel members to each other through welding, bolt connection, or riveting. Steel structure is a very important type of building structure in modern architecture, with various characteristics and advantages: Steel has high strength, good plasticity, and toughness, enabling the steel structure to bear large loads while having a relatively light self-weight, which is convenient for transportation and installation; The homogeneity and isotropy of steel are good, making the overall stiffness of the steel structure good and capable of resisting various forms of deformation; Steel structure components can be prefabricated in the factory and assembled on-site, with a fast construction speed, which is conducive to shortening the construction period. Due to its unique advantages, steel structures are widely used in large factories, stadiums, super high-rise buildings, bridge projects, offshore platforms, temporary buildings, and other fields.

[0003] The connection of steel structure nodes plays a crucial role in the design and construction of steel structures. Through the connection nodes, different steel members (such as horizontal members, vertical members, or diagonal members) can be tightly connected to form a stable whole, thereby improving the rigidity and stability of the steel structure. Moreover, the connection nodes can disperse the load to each member, effectively reducing the load pressure on a single member, alleviating the stress level of the steel structure, and thus extending the service life. However, the existing steel structure nodes usually use connectors in combination with bolts for connection. This connection structure is relatively simple. During the specific connection operation, it is necessary to manually align the steel structure members, which is difficult to ensure the flatness of the connection, not convenient for positioning the steel structure members, affecting the construction efficiency, and the fixing effect is not good enough. After long-term use, the connection is prone to looseness, affecting the structural safety. Therefore, there is an urgent need for a steel structure node connector with a simple structure, convenient installation, and firm connection. Summary of the Utility Model

[0004] In view of the existing deficiencies, the utility model provides a steel structure node connector, aiming to optimize the connection structure, improve the connection convenience of steel structure members, and improve the construction efficiency and ensure the connection strength.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A steel structure node connector includes a first steel member and a second steel member. The first steel member and the second steel member are connected by two sets of node connection mechanisms. The two sets of node connection mechanisms are respectively arranged on the left and right sides of the connection between the first steel member and the second steel member. The two sets of node connection mechanisms are connected to the first steel member and the second steel member by multiple first bolts, and the ends of the first bolts are locked and tightened by first nuts.

[0007] The node connection mechanism includes a side support plate, a node connection plate, connection holes and positioning chucks. The node connection plate is vertically attached to the connection between the first steel member and the second steel member. Multiple connection holes for connecting the first bolts are opened inside the node connection plate. Two groups of positioning chucks are welded on the front and back sides of the upper and lower ends of the node connection plate.

[0008] Furthermore, multiple first screw holes corresponding to the connection holes are opened inside both the first steel member and the second steel member.

[0009] Furthermore, a second screw hole runs through the inside of the positioning chuck. Third screw holes are opened on the upper end faces of both the first steel member and the second steel member. The positions of the second screw hole and the third screw hole correspond to each other. A second bolt is assembled inside the second screw hole and the third screw hole, and the outer end of the second bolt is locked and tightened by a second nut.

[0010] Furthermore, the positioning chuck is arranged in a U-shaped structure and can be clamped at the edges of the first steel member and the second steel member.

[0011] Furthermore, the outer end face of the positioning chuck is thickened.

[0012] Furthermore, two groups of second rib plates are symmetrically welded on the upper surface of the positioning chuck.

[0013] Furthermore, side support plates with a right-angle structure are fixedly arranged at the upper and lower ends near the front and back sides of the node connection plate. The horizontal outer surfaces of the side support plates are attached and connected to the inner surfaces of the first steel member and the second steel member.

[0014] Furthermore, multiple triangular first rib plates are uniformly welded at the inner corners of the side support plates.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. Through the design of the node connection mechanism, the present utility model ensures that the steel members at the node can be accurately aligned during connection, without excessive manual adjustment, thereby improving the flatness and accuracy of the connection, simplifying the on-site construction process at the same time, and improving the construction efficiency.

[0017] 2. In the node connection mechanism of the present utility model, not only is it connected to the steel member through multiple groups of first bolts, but also a second bolt connection is provided at the positioning card seat, forming a double fixation, significantly enhancing the strength and stability of the connection node.

[0018] 3. The positioning card seat in the present utility model is set as a U-shaped structure, and the positioning card seat can be clamped at the edges of the first steel member and the second steel member. The U-shaped structure enables the positioning card seat to have a larger contact area and better stability. When the positioning card seat is clamped at the edge of the steel member, it can closely fit the surface of the steel member, thereby providing firm support and positioning. The design of the U-shaped positioning card seat makes the installation process more simple and efficient. The construction personnel only need to align the positioning card seat with the edge of the steel member and then snap it in. The design reduces the alignment and adjustment time during the installation process and improves the construction efficiency. In addition, through the clamping of the U-shaped positioning card seat, extra stability and support can be provided for the connection point, realizing the rapid positioning between steel structure members, preventing the steel members from moving or misaligning during the connection process, and thus ensuring the accuracy and tightness of the connection.

[0019] 4. The outer end face of the positioning card seat in the present utility model is thickened. The thickening treatment can significantly increase the local stiffness of the positioning card seat at the connection point, enhance the bearing capacity, contribute to improving the stress distribution state of the positioning card seat at the connection point, reduce stress concentration, and prevent the positioning card seat from deforming.

[0020] 5. The side support plate with a right-angle structure provided in the present utility model provides extra support for the node connection plate, enhancing the overall stiffness of the node connection part and enabling it to better withstand the transfer force from the steel member. At the same time, the side support plate helps to disperse the stress at the connection part over a larger area, avoiding stress concentration, thereby improving the bearing capacity of the connection node. In addition, the installation process is simplified through the side support plate, providing clear positioning and support for the node connection plate and reducing the adjustment work during installation.

Detailed implementation manners

[0028] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Embodiment:

[0030] As Figures 1 to 6 shown, a steel structure node connector includes a first steel member 1 and a second steel member 3. The first steel member 1 and the second steel member 3 are connected by two groups of node connection mechanisms 2. The two groups of node connection mechanisms 2 are respectively arranged on the left and right sides of the connection between the first steel member 1 and the second steel member 3. The two groups of node connection mechanisms 2 are connected to the first steel member 1 and the second steel member 3 through multiple groups of first bolts 5. The end of the first bolt 5 is locked and tightened by a first nut 4;

[0031] The node connection mechanism 2 includes a side support plate 21, a node connection plate 22, a connection hole 23 and a positioning seat 24. The node connection plate 22 is vertically attached to the connection between the first steel member 1 and the second steel member 3. Multiple groups of connection holes 23 for connecting the first bolts 5 are provided inside the node connection plate 22. Two groups of positioning seats 24 are welded on the front and back sides of the upper and lower ends of the node connection plate 22. This design solves the problems that the existing node connection structure is relatively simple, manual alignment of steel structure components is required during specific connection operations, it is difficult to ensure the flatness of the connection, it is not convenient to position the steel structure components, affecting the construction efficiency, and the fixing effect is not good enough. After long-term use, the connection is prone to looseness, affecting the structural safety.

[0032] In this embodiment, multiple groups of first screw holes 6 corresponding to the connection holes 23 are provided inside both the first steel member 1 and the second steel member 3. The first screw holes 6 are used to connect the first bolts 5, facilitating the connection between the node connection plate 22 and the first steel member 1 and the second steel member 3.

[0033] In this embodiment, a second screw hole 7 is formed through the inside of the positioning clamping seat 24. Third screw holes 29 are formed in the upper end surfaces of the first steel member 1 and the second steel member 3. The positions of the second screw hole 7 and the third screw hole 29 correspond to each other. A second bolt 25 is assembled inside the second screw hole 7 and the third screw hole 29, and the outer end of the second bolt 25 is locked and tightened by a second nut 26. This design realizes the stable connection between the positioning clamping seat 24, the first steel member 1, and the second steel member 3 through the second screw hole 7, the second bolt 25, and the second nut 26, and further realizes the double connection between the node connection mechanism 2, the first steel member 1, and the second steel member 3, enhancing the stability and bearing capacity of the connection.

[0034] In this embodiment, the positioning clamping seat 24 is arranged in a U-shaped structure and can be clamped at the edges of the first steel member 1 and the second steel member 3. The U-shaped structure enables the positioning clamping seat 24 to have a larger contact area and better stability. When the positioning clamping seat 24 is clamped at the edge of the steel member, it can closely fit the surface of the steel member, thereby providing firm support and positioning. The design of the U-shaped positioning clamping seat 24 makes the installation process simpler and more efficient. The construction workers only need to align the positioning clamping seat 24 with the edge of the steel member and then snap it in. This design reduces the alignment and adjustment time during the installation process and improves the construction efficiency. In addition, through the clamping of the U-shaped positioning clamping seat 24, additional stability and support can be provided for the connection point, realizing the rapid positioning between steel structure members, preventing the steel members from moving or being misaligned during the connection process, and thus ensuring the accuracy and tightness of the connection.

[0035] In this embodiment, the outer end face of the positioning clamping seat 24 is thickened. The thickening treatment can significantly increase the local stiffness of the positioning clamping seat 24 at the connection point, enhance the bearing capacity, contribute to improving the stress distribution state of the positioning clamping seat 24 at the connection point, reduce stress concentration, and prevent the positioning clamping seat 24 from deforming.

[0036] In this embodiment, two groups of second rib plates 28 are symmetrically welded on the upper surface of the positioning clamping seat 24. As a strengthening member, the second rib plate 28 can significantly improve the bearing capacity and bending stiffness of the positioning clamping seat 24 in the vertical direction, contribute to the positioning clamping seat 24 remaining stable when bearing the transfer force between the first steel member 1 and the second steel member 3, reduce deformation, ensure the reliability of the connection, and at the same time, the concentrated stress can be effectively dispersed through the second rib plate 28 to avoid local damage due to excessive stress.

[0037] In this embodiment, side support plates 21 with a right-angle structure are fixedly provided at both the front and rear sides of the node connection plate 22 near the upper and lower ends. The horizontal outer surfaces of the side support plates 21 are in fitting connection with the inner surfaces of the first steel member 1 and the second steel member 3. The side support plates 21 with a right-angle structure provide additional support for the node connection plate 22, enhancing the overall stiffness of the node connection and enabling it to better withstand the transfer forces from the steel members. At the same time, the side support plates 21 help to disperse the stress at the connection to a larger area, avoiding stress concentration, thereby improving the load-bearing capacity of the connection node. In addition, the installation process is simplified through the side support plates 21, providing clear positioning and support for the node connection plate 22 and reducing the adjustment work during installation.

[0038] In this embodiment, multiple groups of triangular first rib plates 27 are evenly welded at the internal corners of the side support plates 21. This design enhances the load-bearing capacity at the corners through the multiple groups of first rib plates 27, reducing the possible deformation during the stress process. Moreover, the first rib plates 27 can disperse the stress concentration at the internal corners of the side support plates 21, making the stress distribution more uniform and improving the structural strength and durability of the side support plates 21.

[0039] The working principle of this steel structure node connector is as follows: First, the node connection plate 22 is vertically attached to the connection between the first steel member 1 and the second steel member 3. At the same time, by utilizing the U-shaped structure of the positioning clamp seat 24, the positioning clamp seat 24 is clamped at the edges of the first steel member 1 and the second steel member 3 to achieve preliminary positioning. The quick clamping of the U-shaped positioning clamp seat 24 shortens the alignment and fixing time of the steel structure members, improving the construction efficiency. Multiple groups of first bolts 5 are passed through the connection holes 23 on the node connection plate 22 and screwed into the first screw holes 6 inside the first steel member 1 and the second steel member 3, and the first nuts 4 are used to initially fix the node connection plate 22 to achieve a stable connection between the first steel member 1 and the second steel member 3. Then, the second bolts 25 are passed through the second screw holes 7 inside the positioning clamp seat 24 and screwed into the third screw holes 29 at the upper ends of the first steel member 1 and the second steel member 3, and are locked and tightened through the second nuts 26 to achieve double fixation between the node connection mechanism 2 and the steel members. At the same time, the side support plates 21 with a right-angle structure are closely attached to the inner surfaces of the first steel member 1 and the second steel member 3, providing additional horizontal support for the node connection plate 22 and enhancing the overall stiffness.

[0040] In summary, through its unique structural design, this steel structure node connector realizes the rapid, stable, and precise connection between steel structure members. At the same time, it can quickly position the steel structure members at the node connection, improve the construction efficiency, and reduce the construction difficulty.

[0041] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
