ABSTRACT:
A bracing system for a concrete form includes at least one spacer holding and spanning opposing sides of the form, and at least one inclined strut. The strut, at its upper end, attaches to the spacer and, at its lower end, engages the ground. The strut lower end has a spike and a foot plate for driving the spike into the ground by the user's weight. Preferably, two struts are employed, one on either side of the form. Both attach to the same spacer by dowel sockets and dowel pins. Each strut prevents the form from collapsing on its respective side. Each strut is independently adjustable as to length due to telescoping members having aligned holes, and is locked at a desired length by a spring loaded, captively retained pin. The bracing system is quickly and easily assembled by hand, and is retained in place by pins secured by clips.
