[0021] See also Figure 1-4 As shown, a steel structure building demolition steel material recycling and reuse device comprises an aluminothermic welding generating tank 1, a bottom port of the aluminothermic welding generating tank 1 is connected and installed with a sand cover 2, and a sand pad 3 is arranged directly below the sand cover 2, the sand pad 3 is slidably arranged in a bottom frame 11, and one end of a guide column 12 is extended into a group of guide holes 301 located on both sides of the sand pad 3, a spring 13 is sleeved on the guide column 12, and the bottom end of the guide column 12 is fixedly connected to the bottom of the bottom frame 11, two hinges 14 are symmetrically arranged on the left end of the top of the sand pad 3, and the two hinges 14 are movably connected to the two ends of a U-shaped pressure rod 15 respectively, a connecting frame 4 located on one side of the aluminothermic welding generating tank 1 is rotatably connected to a bearing 18 located on a screw hole slider 7 through a flange shaft 6, the screw hole slider 7 is threadedly connected to a lead screw 9 located in a strip frame 8, and corresponding parts on both sides of the strip frame 8 are rotatably connected to corresponding parts of the U-shaped pressure rod 15 through rotating shafts;

[0022] The ignition end of the igniter 5 extends into the tank mouth of the thermite welding tank 1, and the outer end of the igniter 5 is fixedly connected to the connecting frame 4. The flux placed in the thermite welding tank 1 is ignited by the igniter 5 to obtain molten iron for welding.

The position movement of the overall structure can be completed through the handle 10 and the universal wheel 17.

[0024] like Figure 2 and Figure 4 As shown, the upper and lower high-position displacement range of the hinge 14 is within the range of 1 cm to 2 cm, which can form an upper and lower displacement and exert downward pressure on the sand pad 3; a spring 13 is mounted on the guide column 12, and the two ends of the spring 13 are respectively connected to the adjacent structures; the screw hole slider 7 is in sliding contact with the inner wall of the strip frame 8; the top end of the screw 9 is located outside the strip frame 8, and a turning handle is installed on the top end of the screw 9.
