Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure connection device. Background Art

[0002] Steel structure connections are devices and components used to connect and fix steel structure elements. These connections play a vital role in steel structure projects such as buildings, bridges, and industrial facilities. They need to have strong bearing capacity, reliable connection performance, and flexibility to adapt to different engineering requirements.

[0003] After searching, the Chinese patent with publication number CN219852912U: A steel structure building connection device, involving the technical field of steel structure building, includes a connection platform, baffles are fixedly connected at the four corners of the upper surface of the connection platform, and two sliding rods are fixedly connected to one side surface of the two groups of baffles. The left and right sides of the two sliding rod walls are slidably connected to the strip plates, and the front and rear sides of the upper surfaces of the two strip plates are fixedly connected to support rods. The above technical solution can be driven by a reciprocating motor to drive the two-way screw rod to drive the moving blocks on both sides to move outward or inward, so that the strip plate drives the sleeve ring to adjust according to the required length of the connected steel structure, and then the bolt is rotated to move the arc sleeve downward, so that the anti-slip pad is in contact with the surface of the steel structure to prevent offset and shaking during the connection process, and the movement of the strip plates is limited and guided by the sliding rods on both sides, thereby improving the efficiency of steel structure connection. However, the above technical solution still has the following shortcomings when actually used:

[0004] The above technical solution clamps and fixes the steel structure through the collar and the arc-shaped sleeve. The arc-shaped sleeve is of adjustable design, which facilitates the collar and the arc-shaped sleeve to clamp steel structures of different sizes. Although this structure can expand the scope of application of the device, when clamping and fixing steel structures of different sizes, the contact area between the collar and the arc-shaped sleeve on the surface of the steel structure is limited, resulting in poor clamping effect of the collar and the arc-shaped sleeve on the steel structure, making the steel structure easy to shake during welding, which is not conducive to the connection between steel structures.

[0005] Therefore, it is necessary to design a steel structure connection device to solve the above problems. Utility Model Content
