Resistance welding technique for concrete reinforcement structure - has mechanism to introduce diagonal members through chute and moves longitudinal members stepwise

摘要

The reinforced concrete structures consist of longitudinal rod supports and diagonal wire struts which connect the rods. The upper and lower-longitudinal supports are moved stepwise in parallel planes. There are one upper and two lower supports. The diagonal struts are fed in from a chute (1) in the direction of the diagonals. The infeed chute has a guide at the lower end which is placed at the same angle as the diagonals. The guide has a cut-out through which the counter electrode (10) passes and this engages with the upper support electrode (22). The in-feed chute has an arrangement which separates the cross struts.
