US 5,078,360 A · Prefabricated assembly for poured concrete forming structures

Abstract

There is provided a modular assembly for poured concrete forming, including a plurality of interconnecting rigid panel members having a rear portion and front facing for contact with poured concrete to form a mold surface. The rear portion of the panel members provides at least two flanges extending generally rearwardly of the front facing, each of the flanges being longitudinally disposed respectively adjacent each of at least two opposed terminal edges of the panel members. Adjacent the front facing of the panel members, a stepped portion is provided at one of the terminal edges of the panels, and a corresponding protruding edge portion is provided at the other of its terminal edges thereof for intimate engagement with the stepped portion of an abutting panel member. The flanges of the panels each provides a mating surface for abutment in intimate contact with an adjacent flange of an abutting panel member. The flanges are adapted for releasably retaining a locking member for securing two abutting panel members. The locking member may be a key member received in slots respectively provided in adjacent flanges of two abutting panels. Alternatively, the locking member may be in the form of a clamp member or scissor type member for engagement with the flanges adjacent longitudinally extending lip members provided at the free terminal ends of the flanges for retaining such locking members.
