Title:
CONCRETE FORM SYSTEM
Document Type and Number:
WIPO Patent Application WO2002068776
Kind Code:
A3
Abstract:
A concrete form system (10) for receiving concrete includes a plurality of interlocking form panels (20) having opposite side ends (24, 26), and which are capable of being selectively arranged in series as a wall of a form configured to receive concrete. A plurality of attachments (42, 46) are each disposed between adjacent form panels (50, 52, 60, 62), and vertically engage the side ends of adjacent form panels to interlock the side ends of the adjacent form panels to resist lateral separation of the adjacent form panels. The attachments include one or more channels (82, 74) or engagement walls (82, 84), and an insert (92, 94) received within the channels or engaging the engagement walls. Ties (130) or brackets (140, 142) can extend between parallel, spaced-apart form panels to maintain a predetermined, spaced-apart distance. A gauge bar (170) can moveably extend into the form to indicate a fill level.
