(7) The previous steps are cycled until enough U-pieces 200 are spot welded on the corrugated web steel 100 and all the U-pieces 200 are placed with C-bars 300; thereafter, the worker fully welds the connection of the U-shaped member 200 with the wing plates 110 of the corrugated web steel 100 and welds the reinforcing bars with the U-shaped member 200.
In step (5) of the present embodiment, since the welding of the U-shaped member 200 and the lowering of the C-shaped reinforcing bars 300 are performed simultaneously, the horizontal distance between the blanking plate 710 and the square tube 510 should be equal to the distance between the adjacent C-shaped reinforcing bars 300 designed on the corrugated web steel 100; as shown in fig. 8, the position of the blanking plate 710 in the mounting slot 411 can be freely adjusted, and a worker can automatically adjust the horizontal distance between the blanking plate 710 and the square tube 510 before processing.
Although embodiments of the present invention have been described in the specification, these embodiments are presented only, and should not limit the scope of the present invention. Various omissions, substitutions and changes in the form of examples are intended in the scope of the invention.
