Meanwhile, the energy-saving and environment-friendly building material reduces the generation of building garbage and the emission of dust.

In addition, the cutting machine is adopted to cut the damaged part, and compared with a flame cutting mode, the cutting machine is safe and reliable and has good cutting quality. Through being equipped with hydraulic stem 11, guarantee on the one hand that 8 realize linear motion of rocking arm, on the other hand has the effect of supporting the cutting machine, and operating personnel uses less power just can control, and convenient easy accuse to guarantee the accurate cutting to the harm position.

The concrete steps of clamping the damaged section steel by the fixing device are that firstly, the fixing bolt 2 is rotated, the fixing block 3 extends into a gap between the boundary beam 20 and the middle beam 19, the fixing plate 1 is placed on the boundary beam 20 and the middle beam 19, then, the fixing bolt 2 is rotated again, two ends of the fixing block 3 extend into rubber strip grooves of the boundary beam 20 and the middle beam 19, and the fixing plate 1 is locked by nuts and fixed on the boundary beam 20 and the middle beam 19. In this embodiment, the length of the fixing block 3 is between the width of the gap between the edge beam 20 and the center beam 19 and the width between the end surfaces of the two adjacent rubber strip grooves or slightly greater than the width between the end surfaces of the two adjacent rubber strip grooves, and the width of the fixing block 3 is smaller than the width of the gap between the edge beam 20 and the center beam 19. Wherein, when the length of the fixed block 3 is slightly larger than the width between the end faces of two adjacent rubber strip grooves, the fixed block 3 can be obliquely arranged.

The specific step of adjusting the cutting position and angle of the cutting machine by the clamping adjusting device is that the cutting machine is driven to slide transversely by adjusting the relative position of the clamping plate 4 on the fixed middle beam 13 so as to adjust the transverse cutting of the cutting machine relative to the damaged part of the section steel. The cutting machine is driven to horizontally rotate by rotating the rotating disc 6 so as to adjust the horizontal cutting angle of the cutting machine relative to the damaged part of the section steel. The cutting machine is driven to vertically move by pulling the rocker arm 8 so as to adjust the vertical cutting position of the cutting machine relative to the damaged part of the section steel.

Further, as shown in fig. 5, the clamping plate 4 includes a first side plate 41, a second side plate 42, an inclined plate 43 and a connecting plate 44, the first side plate 41 and the second side plate 42 are symmetrically disposed, two ends of the inclined plate 43 are fixed to front ends of the first side plate 41 and the second side plate 42, respectively, and two ends of the connecting plate 44 are fixed to rear ends of the first side plate 41 and the second side plate 42, respectively. The connecting plate 44 is provided with a limit bolt 17 which is abutted against the fixed center sill 13.

In the structure, the effect of adjusting the transverse displacement of the clamping plate 4 relative to the fixed middle beam 13 is realized by screwing the limit bolt 17.
