[0032] Working principle:
[0033] When the two parts are connected, the worker observes the position relationship between the limiting block a202 and the limiting block b302 from the side. When the limiting block a202 and the limiting block b302 are in close contact, the front and rear positions of the steel column can be determined. Then, the position of the positioning block a201 and the positioning block b304 is observed. When the positioning block a201 and the positioning block b304 are in close contact, the left and right positions of the steel column can be determined. After the positioning is correct, the I-beam 1 can be slowly lowered. The observation of the position of the reinforcing bar is converted to the position calibration of the limiting block a202, the limiting block b302, the positioning block a201 and the positioning block b304, which reduces the problems of inaccurate calibration and long calibration time. After the position is aligned, the steel drill is used to screw with the limiting hole a203 and the limiting hole b301. When the steel drill is completely inserted, it can be determined that the connection position is correct. Then, the base plate 2 and the base 3 are connected by the bolt through the threaded hole 206. The reinforcing block 204 and the reinforcing bar 205 are fixed on the outside of the I-beam 1 by the bolt, which enhances the connectivity of the I-beam 1, the base plate 2 and the base 3, and strengthens the stability of the bottom of the I-beam 1. When the I-beam steel beam 101 is welded, the position of the I-beam steel beam 101 is fixed first. Then, the connecting block b5 is placed on both sides of the I-beam 1. The second connecting groove 501 is aligned with the top of the I-beam steel beam 101. Then, the connecting block b5 is fixed with the I-beam steel beam 101 by the bolt. Then, the connecting block a4 is placed on the other two sides of the I-beam 1. The connecting block a4 is first located on the top of the I-beam 1, and the groove 401 is aligned with the top of the I-beam steel beam 101. Then, the connecting block a4 is placed vertically, and the first connecting groove 402 is aligned with the connecting plate 502 on both sides of the protrusion, so that the connecting block a4 and the connecting block b5 are connected tightly. Then, the steel drill is used to screw with the positioning hole 403 and the through hole on both sides of the connecting plate 502, so that the connecting block a4, the connecting block b5 and the I-beam 1 are connected and fixed. Through the connection between the connecting block a4 and the connecting block b5, the I-beam 1 and the I-beam steel beam 101 are connected and fixed. During welding, the unstable connection will not cause inaccurate welding and affect the welding quality.
