[0015] 2. Stable and reliable fixing: When the fixing structure cooperates with the first supporting structure or the second supporting structure, the butt joint steel frame is forced downward by gravity, which makes the fixing structure of the rectangular frame clamping more stably fitted on the H-shaped steel frame, thereby enhancing the stability of the overall structure during butt joint and reducing the risk of shaking or displacement.
[0016] 3.

[0032] Remove the first cross arm 14 between the clamping seat 134 in the fixed structure 1, then adjust the length of the adjusting frame 131 in the force clamping unit 13, and make the first sliding seat 12 move in the first sliding groove 5 of the width adjustment frame 11 to adjust the width, at this time the width adjustment frame 11 and the two adjusting frames 131 form a concave shape, which can be fitted on the steel frame; Turn the first screw 132 in the clamping structure, make the second sliding seat 133 move under stress, and move the clamping seat 134 to the H-shaped steel frame with the help of the second sliding seat 133, make the concave clamping seat 134 clamp on the two sides of the H-shaped steel frame, and then realize clamping and fixing; If other shaped steel frames are clamped, the blocking frame 15 can be fixed on the first cross arm 14 by the first bolt 16 and the width can be adjusted; At the same time, the first cross arm 14 is limited between the clamping seats 134 by the blocking frame 15, so that the width adjustment frame 11, the length adjustment frame 131 and the first cross arm 14 form a rectangular frame for clamping; When the first support structure 2 is butt jointed with the fixed structure 1 for support, one end of the first mounting arm 21 is inserted into the butt joint interface 4 in the corresponding butt joint direction, and then the second bolt 135 is screwed into the butt joint interface 4 to tighten the first mounting arm 21; Secondly, the second cross arm 24 between the first mounting arms 21 can bear the butt jointed steel frame, and the second cross arm 24 is limited between the first mounting arms 21 by the blocking piece 25; The spacing of the first mounting arms 21 is adjusted according to the clamping condition of the fixed structure 1, and after the spacing of the first mounting arms 21 is adjusted, the third sliding seat 23 is moved on the second cross arm 24 by the first bearing port 7 to adjust the width; By rotating the second screw 22, the third sliding seat 23 moves in the second sliding groove 6 of the first mounting arm 21 under stress, adjusts the distance between the second cross arm 24 and the fixed structure 1, and then changes the length of the bearing butt joint steel structure and adjusts the bearing gravity and the bearing position; When the second support structure 3 is assembled with the fixed structure 1, one end of the second mounting arm 31 can be inserted into the symmetrical butt joint 4 of the second sliding seat 133 or the symmetrical butt joint 4 at both ends of the width adjusting frame 11 to realize combined installation on the front side or the rear side of the fixed structure 1. The second mounting arm 31 is also fixed by the second bolt 135, and the mounting spacing of the second mounting arm 31 is adjusted according to the actual fixed clamping width, and the spacing adjustment of the second mounting arm 31 can be moved to fit on the third cross arm 33, and the second mounting arm 31 and the third cross arm 33 can be rotatably connected by the second bearing port 8, and the third bolt 32 is fixed; Due to the design of the L-shaped second mounting arm 31 and the hexagonal design, the rotation of the second mounting arm 31 in the butt joint 4 can be adjusted by 60 degrees each time, and the height of the height adjusting unit 34 or the inclination angle of the butt joint can be adjusted. Regardless of the installation inclination angle of the second mounting arm 31, the height adjusting unit 34 is synchronously adjusted on the second mounting arm 31 by the hexagonal design of the second bearing port 8 and the third cross arm 33, and the direction of the bearing roller 346 is realized; and the third screw 342 in the driving adjusting seat 341 can be rotated, so that the fourth sliding seat 343 is forced to move in the opposite direction in the supporting groove 9, and the docking height and position can be adjusted by the force of the steel structure when the bearing roller 346 bears the steel structure., by the gravity of the steel structure, labor-saving descending adjustment is carried out, that is, the third screw 342 is rotated, the supporting rod 344 is forced to overturn to drive the bearing seat 345 to descend, that is, when the butt joint is used, the position is adjusted from high to low. It is more labor-saving.
[0033] In summary, the present application has wide adaptability, high stability and flexible adjustment, which effectively solves the technical defects of the existing steel structure welding butt joint device, provides efficient, safe and precise auxiliary equipment for steel structure construction, and has obvious practical value and popularization significance.
