System for securing concrete form panels

Abstract

An improved concrete form ( 20 ) is provided having spaced apart, opposed, multi-panel wall sections ( 22, 28 ) interconnected by connection assemblies ( 68 ). Each wall section ( 22, 28 ) is made up of at least two form panels ( 24, 26, 30, 32 ) which are placed in side-by-side, abutting relationship. Each form panel ( 24, 26, 30, 32 ) has a planar panel segment ( 34 ) with a pair of projecting, apertured sidewalls ( 42 ) secured to the outer surfaces ( 38 ) thereof. Each segment ( 34 ) has a series of recesses ( 62 ) formed in the butt edges ( 60 ) thereof outboard of the proximal sidewalls ( 42 ), so that when the form panels ( 24, 26 or 30, 32 ) are adjacent each other, a series of through-openings ( 64 ) are cooperatively defined by the recesses ( 62 ). The connection assemblies ( 68 ) include an elongated, threaded connector ( 70 ) of length to bridge the wall sections ( 22, 28 ) and to present threaded end segments ( 78, 80 ) extending beyond the wall sections ( 22, 28 ). Connection clip assemblies ( 74, 76 ) are threaded onto the ends ( 78, 80 ) of the connectors ( 70 ) to interconnect the panels ( 24, 26 and 30, 32 ) as well as the wall sections ( 22, 28 ).
