Description

Technical Field

[0001] This application relates to a steel pipe column base intersecting node structure, belonging to the field of steel structure construction technology. Background Technology

[0002] Steel pipe structures are widely used in large-span spatial structures (such as stadiums and airport terminals), high-rise buildings, and bridge engineering due to their advantages such as high strength, light weight, good seismic performance, and convenient construction. Among them, the steel pipe column base joint is a key part for transferring loads, and its stress performance, construction accuracy, and durability directly affect the safety and economy of the overall structure.

[0003] Currently, traditional steel pipe column base joints have the following technical defects in engineering applications:

[0004] Significant stress concentration and abrupt changes in node stiffness were observed. Internal diaphragm reinforcement was employed, but the quality of internal welding was difficult to inspect. Cast steel nodes, while offering good load-bearing capacity, were expensive, heavy, and difficult to transport and install.

[0005] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a steel pipe column base intersecting node structure to overcome the defects in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a steel pipe column foot intersecting node structure that can improve node stiffness, reduce welding difficulty, and improve construction efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a steel pipe column foot intersecting node structure, including a circular plate, a support plate one vertically installed at the center of the circular plate, two support plates two installed at the center of the circular plate, the two support plates two being located on both sides of the support plate one, the support plate one and the support plate two being perpendicular to each other, and the support plate two being at a certain angle to the circular plate, a main pipe and a branch pipe are installed on the circular plate, the main pipe is coaxially arranged with the circular plate, and the axis of the branch pipe is located at the intersection of the support plate one and the support plate two.

[0008] By adopting the above technical solution, the force transmission path is continuous, stress concentration is reduced, and the stiffness and load-bearing capacity of the nodes are improved. At the same time, the cross-shaped structure is formed between the first support plate and the two second supports, which facilitates the assembly of the main pipe and the branch pipe, and ensures the quality of welding, thus ensuring the stress and stability of the structure.

[0009] The intersecting node structure of the steel pipe column base of this utility model is further configured as follows: the support plate is composed of a rectangular steel plate and another rectangular steel plate. The width of the steel plate is smaller than the width of the steel plate. The steel plate is inclined and covers the steel plate. The steel plate and the steel plate together form the support plate.

[0010] By adopting the above technical solution, steel plate one mainly works with the main pipe, and steel plate two and support plate two mainly work with the branch pipe.

[0011] The intersecting node structure of the steel pipe column base of this utility model is further configured such that: the width of the first steel plate is greater than the diameter of the main pipe, the width of the second steel plate is greater than the diameter of the branch pipe, and the width of the second support plate is greater than the radius of the branch pipe.

[0012] By adopting the above technical solution, when installing the main pipe, the width of steel plate one extends beyond the main pipe, which facilitates welding steel plate one to the main pipe. When installing the support rod, steel plate two and support plate two extend beyond the support pipe.

[0013] The intersecting node structure of the steel pipe column base of this utility model is further configured as follows: a line is provided on the first support plate, and the position of the line is consistent with the connection between the first support plate and the second support plate.

[0014] By adopting the above technical solution, marking lines facilitates the positioning of the two support plates, which is convenient for subsequent assembly.

[0015] The intersecting node structure of the steel pipe column base of this utility model is further configured such that: anti-deformation plates are installed on the top of the main pipe and the branch pipe.

[0016] This utility model discloses a steel pipe column base intersecting node structure, wherein the bottom of the circular plate is provided with a shear-resistant member.

[0017] By adopting the above technical solutions, the horizontal load capacity is improved, shear failure at the bottom of the circular plate is prevented, the bearing capacity of the steel column is increased, and the column deformation is reduced.

[0018] The intersecting node structure of the steel pipe column base of this utility model is further configured such that the shear member can be fitted with concrete.

[0019] The intersecting node structure of the steel pipe column base of this utility model is further configured such that the main pipe and the branch pipe are interconnected.

[0020] The intersecting node structure of the steel pipe column base of this utility model is further configured such that the top of the main pipe and the top of the branch pipe can be connected to the steel pipe column.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The intersecting joint structure of the steel pipe column base in this utility model uses steel pipes as the main body, and the steel pipes are directly connected to each other, so that the force transmission path is continuous, stress concentration is reduced, and the joint stiffness and load-bearing capacity are improved.

[0023] In this utility model, the support plate one and the two support plates two form a cross-shaped structure between the steel pipe column foot intersecting node structure, which facilitates the assembly of the main pipe and the branch pipe, ensures the quality of welding, and guarantees the stress and stability of the structure. The arc-shaped curved panel one and the arc-shaped curved panel two make the junction between the main pipe, the branch pipe and the circular plate natural, with simple lines, which fits the aesthetics of modern architecture.

[0029] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 6 As shown, this utility model is a steel pipe column base intersecting node structure, including a circular plate 41. A support plate 21 is vertically installed at the center of the circular plate 41. Two support plates 31 are installed at the center of the circular plate 41, respectively located on both sides of the support plate 21. The support plates 21 and 31 are perpendicular to each other, and there is a certain angle between the support plates 31 and the circular plate 41. A main pipe 51 and a branch pipe 61 are installed on the circular plate 41. In this embodiment, the main pipe 51 and the branch pipe 61 are steel pipes, and they are interconnected. The diameter of the branch pipe 61 is smaller than that of the main pipe 51. A shear-resistant member 62 is provided at the bottom of the circular plate 41. The shear-resistant member 62 can be reinforced with concrete to improve the horizontal load capacity, prevent shear failure at the bottom of the circular plate 41, and improve the bearing capacity of the steel pipe. Anti-deformation plates 63 are installed at the top of the main pipe 51 and the branch pipe 61 to reduce the deformation of the steel column. The top of the main pipe 51 and the top of the branch pipe 61 can be connected to the steel pipe column.

[0030] Support plate 21 consists of a rectangular steel plate 211 and another rectangular steel plate 212. The width of steel plate 212 is smaller than the width of steel plate 211. Steel plate 212 is inclined and covers steel plate 211. Steel plate 212 and steel plate 211 together form an integrated support plate 21. Steel plate 211 is vertically installed on circular plate 41. There are scribing lines 22 on the center lines of the front and rear sides of steel plate 212. The scribing lines 22 facilitate the positioning of the two support plates 21 for subsequent assembly.

[0031] Support plate 21 is installed at line 22. The two support plates 211 and steel plate 211 form a cross-shaped structure. The width of steel plate 211 is greater than the diameter of main pipe 51, the width of steel plate 212 is greater than the diameter of branch pipe 61, and the width of support plate 211 is greater than the radius of branch pipe 61. When installing main pipe 51, the width of steel plate 211 extends beyond main pipe 51 to facilitate welding of steel plate 211 to main pipe 51. When installing branch pipe 61, steel plate 212 and support plate 21 extend beyond branch pipe 61 to facilitate welding of the cross-shaped structure to branch pipe 61.

[0032] The bottom of the main pipe 51 has a groove that matches the shape of the first support plate 21 and the second support plate 31, and the main pipe 51 is installed on the first support plate 21 and the second support plate 31. The main pipe 51 and the circular plate 41 are coaxially arranged.

[0033] On the side of support plate 2 31 away from main pipe 51, and at the two intersections of the bottom of support plate 1 21 and support plate 2 31, curved panel 1 52 and curved panel 2 53 are respectively installed. The intersections are natural, with simple lines, conforming to modern architectural aesthetics.

[0034] The bottom of the branch pipe 61 has a groove that matches the shape of the main pipe 51, the first curved panel 52, the second curved panel 53, the first support plate 21 and the second support plate 31. The branch pipe 61 is installed on the first support plate 21 and the second support plate 31, and the axis of the branch pipe 61 is located at the intersection of the first support plate 21 and the second support plate 31.

[0035] The working principle of the intersecting joint structure of steel pipe column base of this utility model is as follows:

[0036] First, support plate 21 is welded to the front and rear sides of support plate 21 along the marking lines 22. Support plate 21 is then vertically installed on circular plate 41. Main pipe 51 is fitted onto support plate 21, with its axis aligned with the axis of circular plate 41. Main pipe 51 is then welded to support plate 21. Arc-shaped curved panel 52 and arc-shaped curved panel 53 are welded to the intersection of support plate 1 and support plate 21. Branch pipe 61 is fitted onto support plate 21 and support plate 21. Branch pipe 61 is then welded to support plate 21. Branch pipe 61 is then welded to support plate 21. Shear member 62 is installed on the bottom plate of circular plate 41, and reinforced with concrete around it. Anti-deformation plate 63 is installed inside the top of main pipe 51 and branch pipe 61. Steel pipe columns are connected to the top of main pipe 51 and branch pipe 61, completing the assembly of the steel pipe column foot intersection node structure.
