Abstract: A system for reinforced concrete construction, which relates the bar mat with the molding panels so as to obtain a rigid assembly capable of resisting the pressure of the placed concrete. The system integrates concrete's reinforcement and formwork, thereby making a rigid reinforcement web permitting direct attachment of the molding panels on it, holding them from the inside and avoiding the heavy external structure commonly used to stiffen the forms. This rigid assembly may be obtained by welded joints in the reinforcement web, and, or, using specially designed bar support devices such as tie and spacer units, intended to set in place both reinforcement and sheathing. Thus, the embodiment of the proposed system requires a method of assembly, which considers a combination of standard and invented elements. The latter are reinforcement welded mats and joists, and elements as ties, spacers, washer plates and sleeves for interlocking the bar mat and the molding panels together.
