[0013] From the above technical solutions, the present application has the following advantages:

[0014] 1. In the application, when adjusting the inclination angle of the main support steel, the connected stopper plate ball does not interfere with the inclination of the main support steel, and can clamp and position the main support steel at the same time, preventing the support steel from falling off the equipment and causing accidents, thereby ensuring the normal construction.

[0015] 2. In the application, when the C-shaped steel is placed in the rectangular groove, the electromagnetic plate is energized, the magnetic repulsion force is generated between the magnet positioning plate and the electromagnetic plate, the cylindrical spring is stretched by the magnet positioning plate, and the magnet positioning plate is stretched out of the rectangular positioning groove to limit the C-shaped steel.

It is convenient to assemble and connect the C-shaped steel and the support steel. After the connection is completed, the force machine is used again to pull the L-shaped stop plate, and the L-shaped stop plate is manually rotated so that it no longer extrudes the C-shaped steel. Under the elastic force of the volute spring, the rotated L-shaped stop plate extends into the limiting groove and returns to the initial state.

[0017] 4. In the application, the control plate moves to drive the limiting sliding block to move, thereby changing the included angle of the equal-length rod, and finally adjusting the angle between the C-shaped steels. Since the length of the support steel assembled each time is different, the distance between the C-shaped steels is different. The limiting sliding block ensures that the distance between the equal-length rods changes smoothly with the length of the support steel. The limiting sliding groove guides the limiting sliding block, and the anti-interference groove prevents the electric telescopic rod from interfering with the movement of the control plate in the vertical plane.

steel of the assembled steel structure is placed on the clamping frame 17 for clamping, and the two ends of the main support steel are fixed in length by the fixed-length telescopic frame 21. Then, the C-shaped steel on the assembled steel structure is placed on the fixed limiting frame 22 for positioning. At this time, the left and right electric telescopic rods 13 cooperate with each other to adjust the inclination angle of the main support steel according to the angle ruler 16. The telescopic rod 15 deforms with the inclination angle of the main support steel. The extension support frame 23 is used to make the end of each C-shaped steel close to the main support steel. At this time, the distance between the control block 261 and the positioning block 14, i.e. the distance between the control plate 25 and the positioning block 14, is controlled by rotating the fixed-length screw 26, so as to adjust the opening angle of the support frame 24, so as to control the angle of the C-shaped steel facing the lower end. The control block 261 prevents the control plate 25 from interfering with the fixed-length telescopic frame 21. At this time, the C-shaped steel and the main support steel are connected according to the needs. At this time, the extension support frame 23 is separated from the end of the C-shaped steel, and the C-shaped steel is separated from the fixed limiting frame 22. Finally, the assembled steel structure is moved upward by the elevator 12 until it is close to the assembled roof, and the roof and the assembled steel structure are connected.

The bidirectional screw 173 is driven to rotate by the motor one 174, so as to control the distance between the front and rear clamping plates 171. When the clamping plates 171 move towards each other, the abutting member hemispheres are tightly attached to the front and rear ends of the main support steel of the assembled steel structure, so as to position the main support steel of the assembled steel structure. When the positioning block 14 is driven to move upwards by the left and right electric telescopic rods 13, the tilt angle of the main support steel is adjusted, the rotatably connected abutting member hemispheres do not interfere with the tilting of the main support steel, and the main support steel can be clamped and positioned at the same time, so as to prevent the main support steel from falling off the equipment and causing accidents.
