Description

Technical Field

[0001] This utility model relates to the field of steel beam connection technology, specifically to a steel structure beam with a strong connection. Background Technology

[0002] A steel structural beam is a beam-shaped structural member made of steel, which serves to support and transfer loads in a steel structure. It is typically constructed by welding or assembling steel plates and comes in various cross-sectional shapes and dimensions, such as I-beams and T-beams. Steel structural beams can be used in the beam section of building structures, working in conjunction with other steel components such as steel columns and steel beams to form a complete load-bearing system.

[0003] Currently, there are two methods for connecting steel beams: the first is direct bolt installation, and the second is welding connection. The first method involves lifting the steel beam to the required installation position and then aligning one end of the steel beam with the mounting hole. Because the steel beam is heavy, repeated alignment is required when installing with bolts, which is quite troublesome. In addition, after bolt installation, the bolts are prone to rusting over time, making disassembly difficult. The second method also involves lifting the steel beam to the required installation position without aligning the holes, but it is necessary to maintain the verticality of the steel beam, otherwise the welding will result in tilting.

[0004] Therefore, regardless of whether it is the first or the second method, it is necessary to ensure the alignment of the steel beams for a long time, which makes the installation more troublesome, and the disassembly process is also more difficult. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a steel structure beam with a firm connection, which solves the problems of difficult installation of existing steel beams by screws or welding, and difficult disassembly and assembly later.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a firmly connected steel structure beam, comprising a vertical steel beam and a horizontal steel beam, wherein the vertical steel beam and the horizontal steel beam are fixedly installed by connectors.

[0007] The connector includes a mounting plate, and the surface of the mounting plate is symmetrically provided with cross grooves. The inner cavity of the cross grooves is symmetrically fitted with L-shaped blocks through cross sliders. The L-shaped blocks are rotatably fitted with a first double-ended screw and a second double-ended screw in the horizontal and vertical directions, respectively. The upper and lower opposite sides of the L-shaped blocks are provided with grooves. The surface of the first double-ended screw is threaded with a pressing block. The opposite side of the pressing block is fixedly connected to a telescopic block, and the telescopic block and the grooves are slidably fitted together.

[0008] Preferably, the extrusion block and the L-shaped block abut against each other, with a gap in between.

[0009] Preferably, the mounting plate is fixedly mounted on the surface of the vertical steel beam by screws.

[0010] Preferably, all four corners of the transverse steel beam are inserted into the gaps between the L-shaped block and the extrusion block.

[0011] Preferably, both the first and second double-ended lead screws are fixedly fitted with hexagonal nuts.

[0012] Preferably, the second double-ended lead screw is located between the two upper L-shaped blocks, and the second double-ended lead screw and the first double-ended lead screw are of different sizes.

[0013] This utility model provides a firmly connected steel structure beam. Compared with the prior art, it has the following advantages:

[0014] Beneficial effects:

[0015] 1. This firmly connected steel structure beam is constructed by inserting the four corners of one end of the transverse steel beam into the gaps between the L-shaped blocks and the extrusion blocks. Then, the second double-ended screw is rotated, which moves the upper and lower L-shaped blocks and the extrusion blocks to tighten the transverse steel beam from side to side. Then, the extrusion blocks are raised and lowered on the surface of the first double-ended screw by rotating the first double-ended screw, which raises and lowers the transverse steel beam. This allows the L-shaped blocks and the extrusion blocks to tighten the transverse steel beam from top to bottom. The connector can achieve a stable and firm connection between the vertical and transverse steel beams, and is easy to assemble and disassemble.

[0016] 2. The firmly connected steel structure beam can be adjusted in height with the L-shaped block by raising and lowering the extrusion block. The distance between the L-shaped block and the extrusion block on both sides can be adjusted so that the transverse steel beam can be directly inserted during installation. Then, the transverse steel beam can be fastened by adjusting the first double-ended screw and the second double-ended screw. In addition, it can connect steel beams of different sizes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution: a firmly connected steel structure beam, including a vertical steel beam 1 and a horizontal steel beam 2, which are fixedly installed by a connector 3. The connector 3 can be installed on both sides of the vertical steel beam 1 for the installation of the horizontal steel beam 2 on both sides.

[0024] Please see Figure 2-4 The connector 3 includes a mounting plate 31, which is fixedly installed on the surface of the vertical steel beam 1 by screws. Before installation, the installation position is determined on the vertical steel beam 1, and then the connector 3 is installed on both sides of the vertical steel beam 1. Finally, the vertical steel beam 1 is installed vertically on the ground.

[0025] Furthermore, the surface of the mounting plate 31 is symmetrically provided with cross grooves 37, and the inner cavity of the cross grooves 37 is symmetrically fitted with L-shaped blocks 32 through cross sliders 310. The pressing block 33 abuts against the L-shaped block 32, and there is a gap in the middle. The four corners of the transverse steel beam 2 are inserted into the gap between the L-shaped block 32 and the pressing block 33. The installation method is simpler and more convenient than bolts or welding by direct insertion, which ensures stability and firmness.

[0026] Furthermore, the L-shaped block 32 is rotatably fitted with a first double-ended lead screw 34 and a second double-ended lead screw 35 in both the horizontal and vertical directions. Hexagonal nuts 36 are fixedly fitted onto the surfaces of both the first double-ended lead screw 34 and the second double-ended lead screw 35. The hexagonal nuts 36 are used for clamping an external wrench, allowing direct rotation of the first double-ended lead screw 34 and the second double-ended lead screw 35. This simplifies the tooling process. The second double-ended lead screw 35 is located between the two upper L-shaped blocks 32, and it differs in size from the first double-ended lead screw 34. The second double-ended lead screw 35 is slightly smaller than the first double-ended lead screw 34, thus not protruding from the surface of the L-shaped block 32 and not affecting the installation of accessories on the surface, while also improving aesthetics.

[0027] Furthermore, the L-shaped block 32 has a sliding groove 39 on its upper and lower opposite sides, and a pressing block 33 is threaded onto the surface of the first double-ended screw 34. A telescopic block 38 is fixedly connected to the opposite side of the pressing block 33, and the telescopic block 38 and the sliding groove 39 slide against each other. By limiting the telescopic block 38 in the sliding groove 39, the pressing block 33 can be raised and lowered by rotating the first double-ended screw 34. The raising and lowering of the pressing block 33 can adjust the height between it and the L-shaped block 32. The second double-ended screw 35 can adjust the distance between the two L-shaped blocks 32 and the pressing block 33, so that the transverse steel beam 2 can be directly inserted during installation. Then, the transverse steel beam 2 can be fastened by adjusting the first double-ended screw 34 and the second double-ended screw 35, which is convenient for disassembly and assembly. In addition, it can realize the connection of steel beams of different sizes, and the structure is simple and practical.

[0028] During operation or use, first install the mounting plate 31 onto the surfaces of both sides of the vertical steel beam 1 using screws. Then, fix the vertical steel beam 1 in place. Next, insert the four corners of one end of the transverse steel beam 2 into the gaps between the L-shaped block 32 and the pressing block 33 to overlap them. No repeated alignment is required. Then, using a tool to hold the hexagonal nut 36, rotate the second double-ended screw 35. Simultaneously, due to the connection of the first double-ended screw 34, the upper and lower L-shaped blocks 32 move relative to each other within the cross groove 37. The pressing block 33 also moves accordingly, causing the pressing block 33 to move the transverse steel beam 2 to the left and right. The right side is tightened, and then the first double-ended screw 34 is rotated through the hexagonal nut 36, causing the extrusion block 33 to rise and fall on the surface of the first double-ended screw 34. At the same time, the telescopic block 38 will limit the extension and retraction in the inner cavity of the slide groove 39, driving the transverse steel beam 2 to rise and fall, so that the L-shaped block 32 and the extrusion block 33 tighten the transverse steel beam 2 vertically. The connector 3 can achieve a stable and firm connection between the vertical steel beam 1 and the transverse steel beam 2, and the connection is convenient. In addition, the height and left and right distance between the extrusion block 33 and the L-shaped block 32 can be adjusted through the first double-ended screw 34 and the second double-ended screw 35, so that steel beams of different sizes can be connected.
