Description

Technical Field

[0001] The utility model relates to a square rectangular steel pipe column node structure of a building steel structure, in particular to a square rectangular steel pipe column node structure of a building steel structure. Background Art

[0002] As attached Figure 5 The conventional node structure of the rectangular steel pipe column in the current building steel structure is shown, which is to cut the steel pipe raw material into a number of pipe sections (such as 6 in the figure) at a fixed length, and then connect two outward-extending transverse partitions (such as 7 in the figure) with the pipe sections (6) on both sides thereof in the node area. According to the structural design requirements, the manufacturing process needs to open a groove on the end face of the pipe section (6) on both sides of the transverse partition (7), and install a steel liner around the inner periphery of the port; the two outward-extending transverse partitions (7) and the three pipe sections (6) connected thereto are coaxially butt-jointed and assembled, and then they are welded together at the butt joint.

[0003] Such structural features lead to:

[0004] 1. The process has high requirements and low production efficiency. In order to set the connection plate at the node where the steel column and the steel beam are connected, the whole steel pipe material needs to be cut into several sections, and the ends of each section need to be grooved and installed with inner lining according to the welding technical requirements, and then they are assembled and welded with the extended cross partition to form a whole steel column. Therefore, the process has high requirements and long working hours.

[0005] 2. The quality of components is difficult to control. It is difficult to restore the original straight steel pipe to its original straight state after cutting the originally straight steel pipe into sections and then butting and welding them. In addition, if so many welds are not well controlled, bending and deformation will occur. Therefore, the coaxiality and straightness of the welding are difficult to guarantee.

[0006] 3. High unit manufacturing cost. The low work efficiency leads to long production time, the high welding technology requirements of the weld lead to high technical requirements of the welder, and the consumption of welding materials and auxiliary materials is also high, so the production cost is high. Utility Model Content

[0007] In order to solve the problems existing in the background technology, the utility model specifically proposes a new square rectangular steel pipe column node structure.

[0008] Technical problems solved by the utility model:

[0009] 1) Do not cut off the raw steel pipe to maintain the original integrity of the pipe body and use other methods to ensure the rigidity of the connection between the pipe column node area and the steel beam.

[0010] 2) Simplify the process requirements and change the weld type to reduce the technical requirements for welders, thereby shortening working hours, saving welding materials and auxiliary materials, and reducing unit manufacturing costs.

[0011] The technical solution of the utility model is: a square rectangular steel pipe column node structure of a building steel structure, characterized in that it includes a pipe column body, a pipe wall plate, and an inner partition plate; in a set pipe column body node area, a pipe wall plate is cut from a pipe surface to open a hole in the pipe column body, two inner partition plates are arranged at the horizontal sides of the inner cavity of the hole, and after the inner partition plates are welded to the inner wall of the pipe, the pipe wall plate is reset and welded to the inner partition plate and the pipe mouth wall.

[0012] Furthermore, the tube wall block is cut from a tube surface of the tube column according to the designed size to open a hole in the tube column to expose the inner cavity.

[0013] Furthermore, the inner partition is vertically assembled and welded to the inner wall of the tube at the lateral side of the hole of the tube column.

[0014] Furthermore, the tube wall plate is subjected to secondary processing so as to match the hole size and welding position when it is reset.

[0015] Furthermore, the tube wall plate is assembled and reset to the hole position of the tube column body, and the periphery of the tube wall plate is welded and sealed with the inner partition plate and the tube opening wall.

[0016] Furthermore, one or more connecting plates are arranged on the peripheral surface of the node area of ​​the tubular column, and the steel beam wing plate is connected to the surface of the tubular column and the connecting plates at the position of the inner partition plate.

[0017] Advantages and beneficial effects of the utility model:

[0018] 1. Simple structure simplifies the process requirements. Cut a tube wall plate on a tube surface in the node area of ​​the steel tube to expose the inner cavity of the tube. Use an inner partition to replace the extended transverse partition of the conventional steel tube column node structure to strengthen the rigidity of the steel tube, so as to avoid dividing the steel tube raw material into multiple sections; at the same time, the three sides connecting the inner partition to the tube wall are beveled and welded to the tube wall, instead of beveling the two end faces of each tube section and assembling steel liners on the inner periphery of the port and then welding with the extended transverse partition group; then reset the tube wall plate and seal it with the tube wall and the inner partition on its four sides. It can be seen that the process links are reduced, the processing requirements and welding difficulty are reduced, the working hours are shortened, and the operation efficiency is greatly improved.

[0019] 2. In the case that the steel pipe raw materials are not cut in sections at the node area, the coaxiality and straightness of the steel pipe column can be basically guaranteed. At the same time, the welding of the reinforcement plate and the steel pipe at the node is changed from full penetration welding of the groove of the extended cross partition and the pipe end face to partial penetration welding of the inner partition and the inner wall of the pipe, and only the four sides of the pipe wall plate are fully penetrated for resetting and sealing. Therefore, the welding heat deformation is small, the welding difficulty and the technical requirements for welders and the consumption of welding materials are reduced, and the quality of the components can be effectively guaranteed.
