[0002] Steel structure refers to a building structure made of steel materials, including steel beams, steel columns, steel trusses, etc. Steel structure buildings have the characteristics of light weight, high strength, good earthquake resistance, and fast construction speed.

This structure can quickly install and limit the device through the fixing block 11 and the first bolt 12, thereby facilitating subsequent connection and use.

[0021] In this embodiment, Figure 1 and Figure 2 As shown, a first threaded rotating rod 13 is rotatably installed inside the fixed base 1, and a driving motor 14 is installed on the side end of the first threaded rotating rod 13. This structure can start the driving motor 14 to drive the first threaded rotating rod 13 to rotate, so as to facilitate the adjustment of the subsequent structural position.

[0022] In this embodiment, Figure 1 and Figure 2 As shown, a collar 17 is fixedly installed on the side end of each clamping plate 16, and each clamping plate 16 is slidably installed on the side end of the fixed base 1 through the collar 17 and the first threaded rotating rod 13. A nut 19 is sleeved on the outer surface of the second bolt 18. This structure can quickly adjust the position of the clamping plate 16 through the collar 17 installed on the side end of the clamping plate 16 and the first threaded rotating rod 13, so as to facilitate the rapid installation of steel structure beams with different thicknesses.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a bracket 2 is fixedly installed on the side end of the fixed base 1 on the same side as the clamping plate 16, and a limiting frame 21 is fixedly installed on the side end of the bracket 2.

Then the user turns the handle 25, and the handle 25 drives the second bevel gear 24 to rotate and then drives the two meshing first bevel gears 23 to rotate, thereby driving the second threaded rotating rod 22 to rotate. When the second threaded rotating rod 22 rotates, it cooperates with the connecting sleeve plate 27 to push the two reinforcement support plates 26 away from or close to the left and right sides of the limit frame 21, and then pushes the two sides of the reinforcement support plates 26 to the two sides of the steel structure beam for close fixation. At this time, the connection and fixation of the steel structure beam are completed.
