Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and more specifically, relates to a steel structure connector. Background Technology

[0002] Steel structure connectors are metal parts used to connect steel components, wood components, and components of both steel and wood. Connectors are required in steel structure connections to connect the butt joints of steel components.

[0003] A building steel structure connector, as described in patent application CN202420259467.7, includes a cross-shaped connecting sleeve. An internal support block is fixedly connected inside the cross-shaped connecting sleeve. Four snap-fit ​​sleeves are provided on the cross-shaped connecting sleeve, and a connecting pipe is snapped into the inside of each snap-fit ​​sleeve. L-shaped connecting sleeves are fitted onto the top and bottom of the cross-shaped connecting sleeve. The vertical and horizontal surfaces of the L-shaped connecting sleeves are connected and fixed to the cross-shaped connecting sleeve and the connecting pipe by bolts. This utility model uses the cross-shaped connecting sleeve as the main connecting body. First, the L-shaped connecting sleeve is snapped onto the outside of the snap-fit ​​sleeve. Then, the connecting pipe is inserted into the four snap-fit ​​sleeves on the cross-shaped connecting sleeve, connecting the L-shaped connecting sleeve and the connecting pipe to the snap-fit ​​sleeve. The L-shaped connecting sleeve reinforces the perimeter of the snap-fit ​​sleeve, enhancing its strength in all directions and improving the integrity of the connection. This results in a device with good connection stability and stronger resistance to deformation in all directions.

[0017] Specific Implementation Example 1: Please refer to... Figure 1-3A steel structure connector includes a steel column 10; a corbel beam 11 is fixedly connected to one side of the steel column 10; a steel crossbeam 12 is abutted to one side of the corbel beam 11; the upper and lower ends of the corbel beam 11 and the steel crossbeam 12 respectively abut against pressure plates 13; the pressure plates 13 have two pairs of sliding grooves 23; a pair of fastening bolts 17 are slidably connected to the inner side of each sliding groove 23; a locking nut 22 is threadedly connected to the side of each fastening bolt 17 away from the bolt head; the corbel beam 11, the steel crossbeam 12 and the pair of pressure plates 13 are fixed together by the fastening bolts 17 and the locking nuts 22; it also includes support rods 20 fixedly connected to both ends of the upper pressure plate 13; each The lower end of the support rod 20 is fixedly connected to the platform plate 21; an adjustment plate 14 is provided on the outer side of each pressure plate 13; the outer side of each adjustment plate 14 abuts against the side of the locking nut 22 near the steel beam 12; each adjustment plate 14 has a corresponding slide groove 15 opened on the slide groove 23; by setting the pressure plate 13, adjustment plate 14, fastening bolt 17, locking nut 22, connecting rod 18, and limiting groove 19, the distance between the two adjustment plates 14 can be controlled to adapt to the welding of steel beams of different sizes, which improves practicality. At the same time, welding can be carried out by means of the gap of the welding avoidance groove 16 and the welding avoidance groove 24, which improves welding efficiency.

[0018] Please see Figure 2 The upper adjusting plate 14 is rotatably connected to the connecting rod 18; the lower adjusting plate 14 has a limiting groove 19; the lower end of the connecting rod 18 is slidably connected to the limiting groove 19; the pressure plate 13 is made of stainless steel; the adjusting plate 14 is made of stainless steel; the pressure plate 13 has a second welding clearance groove 24; each adjusting plate 14 has a first welding clearance groove 16 corresponding to the second welding clearance groove 24; the upper surface of the platform plate 21 is chrome-plated; there is a gap between the support rod 20 and the lower adjusting plate 14; the connecting rod 18 is made of cast iron; by setting the support rod 20 and the platform plate 21, a foothold is provided for welding, improving welding efficiency and welding safety.

[0019] During operation, two pressure plates 13 are attached to the corbel beam 11 and the steel crossbeam 12, so that the welding clearance groove 16 is aligned with the connection between the corbel beam 11 and the steel crossbeam 12; then the adjusting plate 14 is pressed onto the pressure plate 13, and the locking nut 22 is tightened so that the adjusting plate 14 is pressed tightly against the pressure plate 13, and at the same time the pressure plate 13 is pressed tightly against the corbel beam 11 and the steel crossbeam 12. After tightening the locking nut 22, the fixing is completed. When adjusting the lower pressure plate 13 and adjusting plate 14, the lower end of the connecting rod 18 slides due to the movement of the lower adjusting plate 14, which can adapt to steel beams of different sizes. The two adjusting plates 14 are connected by the connecting rod 18 to prevent the lower adjusting plate 14 and pressure plate 13 from falling quickly due to external force, thus improving safety. After the connection is completed, the worker can step onto the platform plate 21 and weld the steel beam by welding the first relief groove 16 and the second relief groove 24. Then, the longitudinal welds of the bracket beam 11 and the steel crossbeam 12 are welded. Since there is a certain distance between the connection of the bracket beam 11 and the steel crossbeam 12 and the connecting rod 18, it will not affect the welding between the bracket beam 11 and the steel crossbeam 12. After the welding is completed, the locking nut 22 is loosened, the entire connecting part is removed, and put into the cycle of welding.
