Multi-panelled concrete forming structure for forming flat curved walls

Abstract

A modular concrete form structure including a series of at least three vertically extending rows of concrete form panels to be joined together in side-by-side relation as a gang for use in the formation of straight or curved concrete walls. The panels have confronting slotted panel margins about their perimeters. Fasteners secure the confronting panel margins in side-by-side relation. A series of spaced vertically aligned a horizontally positioned mini-walers are provided for mounted disposition in lapped engagement against the confronting slotted panel margins. The mini-walers each have a width exceeding the width of the form panel and being of sufficient additional width to extend over joints formed between the confronting slotted panel margins at opposite sides of each panel to provide a backing. Fasteners are provided for securing the spaced vertically aligned horizontally positioned mini-walers to the panels. An upright strongback structure is mounted in abutment against said spaced vertically aligned horizontally positioned mini-walers generally in right angle relation thereto. Fastener means secures the strongback structure in unitary assembly with the panels.
