Description

Technical Field

[0001] This utility model relates to the technical field of steel column connection nodes, specifically to spatial double-slope steel column nodes without corbels. Background Technology

[0002] In the field of steel structure construction, spatial double-slope structures are widely used in large-span building scenarios such as stadiums, exhibition halls, and transportation hubs due to their advantages such as large spatial span, beautiful appearance, and superior structural performance. In this type of structure, the connection node between steel columns and steel beams is the core component that ensures overall stability. Traditional connection methods mostly rely on corbel nodes to connect steel columns and steel beams, but this technical solution has many unavoidable defects.

[0003] First, the traditional corbel joint is difficult to process and transport. The corbel is an irregularly shaped component and needs to be customized according to the slope angle of the double-slope structure and the span of the steel beam. The processing accuracy requirements are strict. Even a slight deviation will affect the subsequent installation. In addition, the protruding corbel structure increases the overall volume and irregularity of the component. During transportation, the corbel is easily deformed and damaged due to collisions. This not only increases the transportation cost, but also requires additional manpower for repairs and delays the construction period.

[0004] Secondly, traditional joint stress concentration and structural stability are insufficient. The connection between the corbel and the steel column is a typical stress concentration area. When the spatial double-slope structure is subjected to external forces such as roof load and temperature deformation, this area is prone to fatigue damage. Long-term use may lead to joint cracking and reduce the overall structural stability. Utility Model Content

[0005] The purpose of this utility model is to provide a spatial double-slope steel column without corbel joints in order to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a spatial double-slope steel column without corbel nodes, including a steel column, wherein node plates are fixedly connected to the four sides of the steel column, steel beams are fixedly connected to the node plates, and a reinforcing component is fixedly installed between two adjacent steel beams. The reinforcing component and the two steel beams can cooperate in the length direction to form a triangular support structure. Support components are fixedly connected to the four longitudinal edges of the steel column to reinforce the node plate and limit the vertical movement of the reinforcement components.

[0007] The above-mentioned spatial double-slope steel column without corbel joints is adopted: The node plate is first welded to the steel column, and then fixed with bolts once or twice to ensure accurate positioning. The steel beam is positioned by welding to the steel column perpendicular to the steel beam through the first rib plate at the top and bottom, and then reinforced with bolts to complete the connection with the node plate. The roof and horizontal loads are first transferred to the steel beams, and then distributed to the steel columns through the contact of the node plates. The first rib plate assists in tensile resistance and support, optimizing the force path. The reinforcement components between adjacent steel beams are fixed by ear plates. The fixing rods are at the same angle as the steel beams, forming a triangular structure to further distribute the load and prevent deformation of the steel beams. The fixing rod of the reinforcement component is connected to the ear plate by bolt two. The triangular structure restricts the change of the included angle of the steel beam and prevents lateral displacement. The reinforcement plate of the support component is attached to the steel column and the node plate through the stepped groove to enhance the connection. The support plate is set along the diagonal of the steel column. The slot limits the fixing rod. The second rib plate strengthens the support plate and prevents breakage.

[0008] Preferably, the node plate is welded to the steel column, and a number of bolts are provided on the node plate to fix it to the steel column.

[0009] Preferably, the top and bottom of the steel beam are fixedly connected with first ribs, which are fixedly connected to the node plate and the steel column.

[0010] Preferably, the first rib is perpendicular to the top of the steel beam and the side of the steel column.

[0011] Preferably, the reinforcement component includes a fixing rod, and both ends of the fixing rod are fixedly connected to ear plates by bolts. The two ear plates are respectively fixedly connected to two adjacent steel beams.

[0012] Preferably, the angle between the fixing rod and the two adjacent steel beams is the same.

[0013] Preferably, the support assembly includes a reinforcing plate fixedly connected to the steel column, a support plate fixedly connected to the reinforcing plate, and a slot provided on the support plate, with the fixing rod fitting into the slot with a clearance.

[0014] Preferably, the reinforcing plate has stepped grooves, and the stepped grooves are fitted with the steel column and the surfaces of the two adjacent node plates with clearance.

[0015] Preferably, the support plate is fixedly connected to the top and bottom of the support plate, and the second rib is fixedly connected to the reinforcing plate and the steel column.

[0016] Preferably, the support plate is arranged along the diagonal direction of the steel column.

[0017] The beneficial effects are: 1. The traditional corbel component is eliminated, and a simplified connection mode between steel columns and gusset plates is adopted. The gusset plates and reinforcement components are all regular components, eliminating the need for custom-made irregular corbels. This significantly reduces processing difficulty, enabling standardized mass production and reducing processing errors and material waste. At the same time, the absence of protruding corbels makes the overall shape of the steel columns regular, less prone to deformation and damage during transportation, and reduces transportation protection and repair costs.

[0018] 2. The gusset plate extends to the web and flange of the steel beam, transferring loads through surface contact. Combined with the function of the first rib, it evenly distributes the steel beam load to the steel column, avoiding the localized stress concentration problem of traditional corbel joints. The reinforcement component and adjacent steel beams form a triangular support structure, utilizing the geometric stability of triangles to effectively disperse roof loads and horizontal forces, improving the joint's shear and torsional resistance.

[0019] 3. The support components are tightly fitted to the steel columns and node plates through the stepped grooves of the reinforcing plates, increasing the contact area and further reinforcing the connection between the node plates and the steel columns. The support plates are set along the diagonal of the steel columns, and together with the reinforcement effect of the second rib plate, they form a stable support for the reinforcing components, preventing deformation of the fixed rods. Together with the reinforcing components, they form a frame structure, improving the overall stiffness of the node and enabling it to withstand the long-term load of a large-span, double-slope structure, ensuring the safety and stability of the structure.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See Figures 1-4 As shown, this utility model provides a spatial double-slope steel column without corbel nodes, including a steel column 1, with node plates 2 fixedly connected to all four sides of the steel column 1, steel beams 5 fixedly connected to the node plates 2, and a reinforcing component 6 fixedly installed between two adjacent steel beams 5. The reinforcing component 6 and the two steel beams 5 can form a triangular support structure by cooperating in the length direction. Support components 7 are fixedly connected to the four longitudinal edges of the steel column 1 to reinforce the node plate 2 and to limit the vertical movement of the reinforcement components 6.

[0025] In this embodiment, there are at least four reinforcing components 6. These reinforcing components 6, together with the steel beams 5 installed on the steel columns 1, can form a frame structure, further improving the stability of the steel beams 5 installed on the steel columns 1.

[0026] As an optional implementation, the node plate 2 is welded to the steel column 1, and a number of bolts 3 are provided on the node plate 2. The node plate 2 is fixedly connected to the steel column 1 by the bolts 3, and the node plate 2 can be further reinforced by the bolts 3.

[0027] As an optional implementation, the top and bottom of the steel beam 5 are fixedly connected with first ribs 4. The first ribs 4 are fixedly connected to the node plate 2 and the steel column 1. The upper first rib 4 has a tensile force acting on the steel beam 5, and the lower first rib 4 is used to support the steel beam 5.

[0028] Furthermore, the first rib 4 is perpendicular to the top of the steel beam 5 and the side of the steel column 1, which maximizes the effectiveness of the first rib 4.

[0029] As an optional implementation, the reinforcement component 6 includes a fixing rod 13, with ear plates 14 fixedly connected to both ends of the fixing rod 13 by bolts 15. The two ear plates 14 are fixedly connected to two adjacent steel beams 5 respectively. The fixing rod 13 can support the two adjacent steel beams 5, so that the included angle between the two adjacent steel beams 5 remains unchanged.

[0030] Furthermore, the angle between the fixing rod 13 and the two adjacent steel beams 5 is the same, which is designed to ensure that the fixing rod 13 is subjected to uniform force.

[0031] As an optional implementation, the support assembly 7 includes a reinforcing plate 11 fixedly connected to the steel column 1, a support plate 8 fixedly connected to the reinforcing plate 11, a slot 9 provided on the support plate 8, and a fixed rod 13 clearance fits with the slot 9. By supporting the fixed rod 13 with the support plate 8, the stability of the fixed rod 13 can be improved and deformation of the fixed rod 13 can be prevented. If the fixed rod 13 remains unchanged, the stability of the connection node can be consolidated. The supporting component 7 and the reinforcing component 6 complement each other and together form the frame structure of the connection node; Furthermore, a stepped groove 12 is provided on the reinforcing plate 11, and the stepped groove 12 is in clearance fit with the surface of the steel column 1 and the two adjacent node plates 2. By setting the stepped groove 12, the contact area between the reinforcing plate 11 and the node plate 2 can be increased, and the reinforcing plate 11 can further improve the firmness of the node plate 2 fixed on the steel column 1. Furthermore, the top and bottom of the support plate 8 are fixedly connected with second ribs 10. The second ribs 10 are fixedly connected with the reinforcing plate 11 and the steel column 1. Since the support plate 8 is a load-bearing component, the second ribs 10 improve the stability of the support plate 8. Furthermore, the support plate 8 is set along the diagonal direction of the steel column 1, which maximizes the function of the support plate 8.

[0032] Using the above structure, the node plate 2 is initially fixed to the steel column 1 by welding. At the same time, bolts 3 are used to penetrate the node plate 2 and the steel column 1 to form a double fixing structure of welding and bolts. This prevents the node plate 2 from falling off or shifting due to welding, and ensures that the node plate 2 is accurately positioned on the four sides of the steel column 1, providing a stable foundation for the connection of the steel beam 5.

[0033] The first rib 4 at the top and bottom of the steel beam 5 is perpendicular to the sides of the steel beam 5 and the steel column 1. One end of the first rib 4 is welded to the steel beam 5, and the other end is welded to the node plate 2 and the steel column 1. This achieves the initial positioning of the steel beam 5 and the node plate 2, and also restricts the vertical displacement of the steel beam 5 by dividing the work of the upper first rib 4 for tension and the lower first rib 4 for support. Subsequently, the steel beam 5 and the node plate 2 are further reinforced with bolts to complete the precise connection between the steel column 1 and the steel beam 5.

[0034] The steel beam 5 transfers the load to the node plate 2 connected to it. The node plate 2 distributes the load evenly to the steel column 1 through surface contact, avoiding the load concentration in a local area. The upper first rib plate 4 bears the tensile force generated by the load on the steel beam 5, and the lower first rib plate 4 bears the vertical pressure of the steel beam 5, assisting the node plate 2 in transferring the load and optimizing the load transfer path.

[0035] The reinforcing components 6 between adjacent steel beams 5 are fixed to the steel beams 5 through ear plates 14. The angle between the fixing rod 13 and the adjacent steel beams 5 is consistent, ensuring that the fixing rod 13 is subjected to uniform force. The triangular support structure formed by the reinforcing components 6 transfers and cancels the horizontal and vertical loads between adjacent steel beams 5, further dispersing the load and preventing a single steel beam 5 from deforming due to excessive load.

[0036] The node plate 2, the first rib plate 4, the reinforcing component 6, the supporting component 7, and the second rib plate 10 together form a complete spatial load-bearing frame, which tightly connects the steel column 1 and the steel beam 5 into one, realizing the uniform transfer of load and the stable support of the structure, and ensuring the safe operation of the spatial double-slope structure.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
