Description

Technical Field

[0001] This invention relates to the field of cross steel column technology, and more particularly to a cross steel column and its processing technology. Background Technology

[0002] Cross-shaped steel columns are a common structural component used to support and reinforce buildings. They are primarily used for structural support and reinforcement in industrial plants, commercial buildings, and large public buildings. Cross-shaped steel columns can withstand vertical loads and provide good bending and torsional resistance through their intersecting structural form.

[0003] The current cross-shaped steel frame mainly consists of an H-beam and T-beams welded to the two side walls of the H-beam. The ends of the cross-shaped steel frame are smooth. The processing flow of this type of cross-shaped steel frame is as follows: cutting and blanking, beveling, assembling the H-beam, assembling the T-beam, straightening the H-beam and T-beam, main cross assembly, and welding and assembling the cross-shaped steel frame. Although the above processing flow can achieve the welding of the cross-shaped steel frame, on the one hand, during the assembly of the cross-shaped column, the above process mainly involves welding a reinforcing rib every 0.5m at the edges of the T-beam and H-beam. This ensures the connection strength of the T-beams and H-beams during welding and prevents bending deformation. After welding, the reinforcing ribs need to be removed by cutting. The welding and disassembly of the reinforcing ribs are cumbersome, resulting in a long processing time and low efficiency for the entire cross column. On the other hand, when assembling two adjacent cross columns into a cross steel frame column, the lack of a reliable structure at the ends of the two adjacent cross columns makes it easy for misalignment to occur when the two adjacent cross columns are aligned and welded, resulting in poor final processing quality of the cross steel frame column. Summary of the Invention

[0004] The purpose of this invention is to provide a cross-shaped steel column and its processing technology in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A cross-shaped steel frame column and its processing technology are disclosed. The cross-shaped steel frame column is composed of an H-beam and T-beams welded to the upper and lower sides of the H-beam. Positioning blocks are welded and fixed to one end of the H-beam and the two T-beams, and positioning grooves matching the positioning blocks are formed at the other ends of the H-beam and the two T-beams. A quick-release reinforcement mechanism for reinforcing and supporting the T-beams during welding is also installed on the outer side of the H-beam. The specific processing steps of the cross-shaped steel frame column are as follows: Step 1: Cutting and blanking. Select suitable steel and cut it into webs and flanges of the corresponding dimensions according to the drawing requirements. Step 2: Beveling. A V-shaped welding bevel is made in the middle of the flange welding surface, and V-shaped platforms corresponding to the V-shaped bevel on the flange are made on both sides of the web. Step 3: Assemble the H-beams by placing the web and flanges on a welding machine and performing automatic welding using a gantry submerged arc welder. Step 4: T-shaped assembly. After assembling the H-beam, split it in half along the middle of the web to obtain the T-beam. Step 5: Straightening process. Straighten the assembled H-beams and T-beams to ensure that the overall structure of the H-beams and T-beams is flat and vertical, without any bending. Step 6: Assemble the cross column. First, lay the assembled H-beam flat and make a welding bevel in the middle of the web of the H-beam. Then, align the edge of the web of the T-beam with the welding bevel on the H-beam. At the same time, use a quick-release reinforcement mechanism to clamp and support the T-beam. Then weld the T-beam to the H-beam. After one T-beam is welded, remove the quick-release reinforcement mechanism. At the same time, flip the H-beam. Then, simply repeat the above welding operation to complete the assembly of the cross column. Step 7: Welding and assembling the cross steel columns. After the cross columns are welded and formed, the positioning blocks and positioning slots are used to achieve reliable assembly of two adjacent cross columns. Then, the connecting parts of the two adjacent cross columns are completely welded to complete the assembly and fixation of the cross steel columns.

[0006] Furthermore, the quick-release reinforcement mechanism includes a guide rail with a groove at the bottom, a bidirectional threaded rod installed in the guide rail, two clamping plates symmetrically installed on the bidirectional threaded rod at two sections with oppositely spiraling threads, connecting rods symmetrically installed on both sides of the bottom end of the guide rail, an L-shaped plate installed at the bottom end of each connecting rod, a hook plate slidably installed on one side of the bottom end of the L-shaped plate, a linkage block welded to one side wall of the hook plate, and a T-shaped adjusting bolt installed on the L-shaped plate and passing through the linkage block. When welding and assembling T-shaped steel and H-shaped steel, the T-shaped steel is first placed on the H-shaped steel, and then the hook plate clamps the two sides of the flange of the T-shaped steel under the action of the H-shaped steel. Then the hook plate is fixed to the bottom end of the web of the H-shaped steel, thereby realizing the reinforcement and support of the T-shaped steel when welding and assembling the H-shaped steel.

[0007] Furthermore, both ends of the bidirectional threaded rod are rotatably connected to the guide rail, and one end of the bidirectional threaded rod has a cross-shaped rotating head. This design allows for convenient rotational adjustment of the bidirectional threaded rod.

[0008] Furthermore, the top end of the connecting rod is hinged to the guide rail, and the bottom end of the connecting rod is hinged to the L-shaped plate. Under the action of the connecting rod, the guide rail and the L-shaped plate can be connected as one unit.

[0009] Furthermore, the T-shaped adjusting bolt is rotatably connected to the L-shaped plate, and the T-shaped adjusting bolt is threadedly connected to the linkage block. Rotating the T-shaped adjusting bolt can adjust the height of the hook plate to reliably tighten the hook plate against the bottom end of the upper flange of the H-beam.

[0010] Furthermore, in step 1, before cutting the steel, it is necessary to remove the impurities on the surface of the steel by wiping and cleaning. This design can effectively avoid the impurities on the surface of the steel from adversely affecting the welding quality during welding.

[0011] Furthermore, in step 3, when assembling the H-beams, the groove weld should first be made with CO2 gas shielded welding for the root pass and then with submerged arc welding for the cover pass. This design can effectively avoid damage defects at the welds on the H-beams in the weld transfer layer.

[0012] Furthermore, in step 4, when assembling the T-beams, an appropriate welding allowance should be reserved in the height direction of the H-beams used for cutting. This design can effectively avoid excessive deformation of the T-beams after welding them onto the H-beams.

[0013] Furthermore, in step 2, a flame cutting machine should be used to cut the bevel, and the oxides on the bevel surface and edge should be cleaned in time after cutting. This design can effectively ensure that the weld width and thickness at the bevel are uniform after welding.

[0014] Furthermore, in step 5, the straightening process of H-beams and T-beams mainly adopts a straightening method that combines mechanical pressure roller straightening with flame straightening, which can effectively ensure the stability of the overall structure of H-beams and T-beams and avoid complete deformation.

[0015] The beneficial effects of this invention are as follows: This invention utilizes a quick-release reinforcement mechanism to support and fix T-shaped steel and H-shaped steel during welding. This avoids excessive deformation of the T-shaped steel and H-shaped steel during welding and also facilitates quick disassembly of the quick-release reinforcement mechanism, avoiding the tedious operations of repeated welding and cutting. This significantly shortens the overall processing time of the cross steel column and improves processing efficiency. At the same time, the invention, in conjunction with positioning blocks and positioning slots, ensures reliable positioning of adjacent cross columns during welding assembly, preventing misalignment between adjacent cross columns during welding and thus improving the final processing quality of the cross steel column.

Straighten the assembled H-beam 1 and T-beam 3 to ensure that the overall structure of H-beam 1 and T-beam 3 is flat and vertical, and there is no bending. Step 6: Assemble the cross column. First, lay the assembled H-beam 1 flat and make a welding bevel in the middle of the web of the H-beam 1. Then, align the edge of the web of the T-beam 3 with the welding bevel on the H-beam 1. At the same time, use the quick-release reinforcement mechanism 4 to clamp and support the T-beam 3. Then weld the T-beam 3 to the H-beam 1. After one T-beam 3 is welded, remove the quick-release reinforcement mechanism 4. At the same time, flip the H-beam 1. Then, simply repeat the above welding operation to complete the assembly of the cross column. Step 7: Welding and assembling of the cross steel columns. After the cross columns are welded and formed, the positioning blocks 2 and positioning slots 5 are used to achieve reliable assembly of two adjacent cross columns. Then, the connecting parts of the two adjacent cross columns are completely welded to complete the assembly and fixation of the cross steel columns.

The linkage block 405 on one side wall of the hook plate 406 and the T-shaped adjusting bolt 404 installed on the L-shaped plate 403 and passing through the linkage block 405 are used to weld and assemble the T-shaped steel 3 and the H-shaped steel 1. First, the T-shaped steel 3 is placed on the H-shaped steel 1. Then, under the action of the hook plate 406, the two sides of the flange of the T-shaped steel 3 are clamped. Then, the hook plate 406 is fixed to the bottom end of the web of the H-shaped steel 1, thereby realizing the reinforcement and support of the T-shaped steel 3 when the H-shaped steel 1 is welded and assembled.

[0020] In this embodiment, both ends of the bidirectional threaded rod 408 are rotatably connected to the guide rail 401, and one end of the bidirectional threaded rod 408 has a cross-shaped rotating head.

Under the action of the connecting rod 407, the guide rail 401 and the L-shaped plate 403 can be connected into one piece.

[0022] In this embodiment, the T-shaped adjusting bolt 404 is rotatably connected to the L-shaped plate 403, and the T-shaped adjusting bolt 404 is threadedly connected to the linkage block 405. Rotating the T-shaped adjusting bolt 404 can adjust the height of the hook plate 406 to achieve reliable clamping of the hook plate 406 to the bottom end of the upper flange of the H-beam 1.

This design can effectively avoid the impurities on the surface of the steel from having an adverse effect on the welding quality during welding.

This design can effectively avoid excessive deformation of the T-shaped steel 3 after welding on the H-shaped steel 1.

[0026] In this embodiment, when processing the bevel in step 2, a flame cutting machine should be used to cut the bevel, and the oxides on the bevel surface and edge should be cleaned in time after cutting. This design can effectively ensure the uniformity of the weld width and thickness at the bevel after welding.
