[0002] Steel structure construction is a new type of building system. Compared with traditional concrete buildings, it uses steel plates or structural steel to replace reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, the construction period is significantly reduced. Publication number CN222414185U discloses a stable, modular steel structure component. It features clamping and fixing components installed on the periphery of the foundation column and cantilever beam, with tie-bar reinforcement components connecting the two clamping and fixing components. This method reinforces the connection between the foundation column and cantilever beam by tightening the two ends of the tie-bar reinforcement components, preventing structural deformation at the joint.

[0003] However, in actual use, since the angle between the clamping and fixing components and the inclined supports is fixed, it is necessary to precisely adjust the angle between the two sets of clamping components during the installation process. Only then can the tie rod pass through the holes on the surfaces of the two sets of inclined supports. The adjustment process is cumbersome and affects the installation efficiency of steel structure components.

[0004] Therefore, it is necessary to invent a lightweight modular steel structure to solve the above problems. Utility Model Content

A main supporting beam 11 is fixedly connected between the left and right sets of supporting columns 1. Multiple secondary supporting beams 12 are fixedly connected between the front and rear sets of main supporting beams 11.

An adjusting component is provided at the end of the supporting rod 3. The adjusting component includes an adjusting screw 32, an adjusting block 33, and a connecting collar 35. A second connecting plate 36 is fixedly connected to both the adjusting screw 32 and the end of the supporting rod 3. A through hole is provided inside the supporting rod 3. The adjusting screw 32 retracts inside the supporting rod 3. The adjusting block 33 is sleeved on the surface of the supporting rod 3. A positioning ring 31 is fixedly connected to one end of the supporting rod 3 near the adjusting screw 32. A positioning groove 34 is provided on the inner wall of the adjusting block 33. The positioning ring 31 is engaged inside the positioning groove 34. A connecting collar 35 is fixedly connected to the side of the adjusting block 33. The connecting collar 35 is threadedly connected to the adjusting screw 32.

[0034] The support column 1 is a cylindrical tube made of Q235B ordinary carbon steel, with a diameter of 89mm and a wall thickness of 4mm. Its height is customized according to usage requirements. The main support beam 11 is I-shaped, made of Q345B high-strength steel, with a thickness of 6mm. Its length is customized according to requirements. The secondary support beam 12 is a rectangular steel tube made of Q235B ordinary carbon steel, with a wall thickness of 4mm. The main support beam 11 is bolted to the support column 1, using M12 standard bolts. The main support beam 11 and the secondary support beam 12 are welded together. 2. Welded to the lower surface of the supporting main beam 11. During construction, first determine the position of each component according to the design drawings, then place the supporting column 1 in the predetermined position and fix it to the foundation with connectors. Next, lift the supporting main beam 11 and fix it between the left and right sets of supporting columns 1 with connectors. After the supporting columns 1 and supporting main beam 11 are fully installed, weld the supporting secondary beam 12 between the two sets of supporting main beams 11. Finally, use the fixing component 2 and the support rod 3 to reinforce the connection between the supporting main beam 11 and the supporting column 1.

[0035] In addition, during the process of fixing the support rod 3, the fixing component 2 is first fixed to the optimal support points on the surfaces of the support column 1 and the support main beam 11 respectively. Then, the second connecting plate 36 at the upper end of the support rod 3 is rotatably connected to the upper fixing component 2. Next, according to the position of the lower fixing component 2, the support rod 3 is rotated and the length of the support rod 3 is adjusted so that the second connecting plate 36 at the lower end of the adjusting screw 32 is connected to the lower fixing component 2, which effectively improves the installation efficiency of the steel structure components.

[0036] See Figure 2 and Figure 4 The fixing component 2 includes a fixing plate 21, a first connecting plate 22, a first screw 23, a sleeve plate 24, a second screw 25, a locking plate 26, and a insertion groove 27. The second connecting plate 26 is rotatably connected to the first connecting plate 22. The first connecting plate 22 is fixed to the side of the fixing plate 21. Two sets of first screws 23 are fixedly connected to both the front and rear ends of the fixing plate 21. The sleeve plate 24 is sleeved on the surface of the two sets of first screws 23. Two sets of second screws 25 are fixedly connected to the right side surface of the first screws 23. Two sets of insertion grooves 27 are opened on the surface of the locking plate 26. One end of the second screw 25 is inserted into the insertion groove 27. The end of the first screw 23 away from the fixing plate 21 and the right end of the second screw 25 are both threadedly connected with locking nuts.

[0037] Meanwhile, during the installation of the fixing component 2, firstly, the fixing plate 21 is attached to the surface of the support column 1. Then, the two sleeve plates 24 on both sides are slid inwards simultaneously, so that the first screws 23 on both sides abut against the surface of the support column 1. Next, the locking nut is rotated inwards to lock the sleeve plates 24 on both sides. Then, the locking plate 26 is fitted onto the right end of the first screw 23, so that the first screw 23 is inserted into the insertion groove 27. The locking plate 26 is then slid to the left. Finally, the locking nut is used to lock the locking plate 26, thus completing the installation of the fixing component 2.

[0038] Specifically, after installing the fixing component 2, the second connecting plate 36 at the upper end of the support rod 3 is clipped onto the outside of the first connecting plate 22 in the upper fixing component 2. Then, bolts are passed through the second connecting plate 36 and the first connecting plate 22 to fix them. Next, the support rod 3 is rotated downwards. At this time, one hand holds the second connecting plate 36 at the end of the adjusting screw 32, and the other hand rotates the adjusting block 33 counterclockwise to push the adjusting screw 32 outwards, extending the support rod 3. The second connecting plate 36 at the end of the adjusting screw 32 is clipped onto the outside of the first connecting plate 22 in the lower fixing component 2. Then, bolts are used to connect and fix them. Next, the adjusting block 33 is rotated clockwise with a tool to slightly retract the adjusting screw 32 inwards, tightening the support rod 3 and increasing the friction between the connecting collar 35 and the adjusting screw 32 to prevent loosening during use.

[0039] See Figure 2 and 6 The fixing component 2 on the surface of the supporting column 1 can be fixed to the upper or lower side of the supporting main beam 11 according to actual usage requirements, thereby fixing the supporting rod 3 to the upper or lower side of the supporting main beam 11, and pulling or supporting the supporting main beam 11 upward.

[0040] The working principle of this utility model is as follows: By fixing the fixing component 2 to the surfaces of the supporting column 1 and the supporting main beam 11 respectively, the second connecting plate 36 at the upper end of the supporting rod 3 is first rotatably connected to the upper fixing component 2. Then, according to the position of the lower fixing component 2, the supporting rod 3 is rotated and the length of the supporting rod 3 is adjusted so that the second connecting plate 36 at the lower end of the adjusting screw 32 is connected to the lower fixing component 2, which effectively improves the installation efficiency of the steel structure components. By sliding the sleeve plate 24 back and forth on the surface of the first screw 23 and the locking plate 26 sliding left and right on the surface of the second screw 25, the inner size of the fixing component 2 is adjusted, so that it can fix the supporting column 1 of different shapes and sizes, effectively improving the adaptability of the fixing component 2.
