The conventional roll-shaped slack type braided rebar is manufactured in a roll shape in advance in a factory or the like, which facilitates storage and transportation before construction and transportation to a base (construction site). The rebar and the flat steel strips are arranged in a vertical and horizontal crossing pattern on the base by a relatively simple on-site work of rewinding and rotating on the base etc. to unfold, removing the take-up core and spreading. Although it is used as a concrete reinforcing bar, the conventional roll-shaped slack type braided bar is a slack type when it is spread on a substrate, etc. by unwinding and unwinding rotation and removing the winding core. The braided bars are likely to be deformed, which may reduce the construction accuracy. Adjacent to a wide area such as a base, etc., a reed type rebar, placement of spacers etc. on the extended rebar type rebar, arranging the upper layer such as rebar There are issues such as the on-site work that is troublesome to remove and collect.

The present invention was developed in order to address the above-mentioned problems, and the object of the present invention is to construct a rebar assembly rebar obtained by welding rebars and flat steel strips in a crosswise manner.
