Abstract
A concrete form system for receiving concrete includes a plurality of interlocking form panels having opposite side ends, and which capable of being selectively arranged in series as a wall of a form configured to receive concrete. A plurality of attachments are each disposed between adjacent form panels, 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 an include one or more channels or engagement walls, and an insert received withing the channels or engaging the engagement walls. Ties or brackets can extend between parallel, spaced-apart form panels to maintain a predetermined, spaced-apart distance. A gauge bar can moveably extend into the form to indicate a fill level.

A concrete form system configured to receive concrete, the system comprising:
- a) a plurality of interlocking form panels having opposite side ends, capable of being selectively arranged in series as a wall of a form configured to receive concrete;
- and
- b) a plurality of attachments, each one disposed between adjacent form panels, which 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.
A concrete form system configured to receive concrete, the system comprising:
- a) a plurality of form panels having opposite side ends capable of being selectively arranged in series with opposing side ends of adjacent form panels being attached together to form a wall of an enclosure configured to receive concrete;
- b) at least one channel, formed along at least one of the side ends of the form panels;
- and
- c) an elongated insert, securable to an adjacent form panel and removably receivable within the at least one channel to attach the side ends of the adjacent form panels.
A concrete form system configured to receive concrete, the system comprising:
- a) a plurality of form panels having opposite side ends capable of being selectively arranged in series with opposing side ends of adjacent form panels being attached together to form a wall of an enclosure configured to receive concrete;
- b) a plurality of channels, each one formed along a length of one of the side ends of the form panels;
- c) a plurality of inserts, each one removably receivable within two channels of adjacent form panels, to interlock the side ends of the adjacent form panels;
- and
- d) at least one tie, configured to be coupled to and extend between parallel, spaced-apart form panels, having opposite ends each attachable to one of the inserts to maintain side ends of the form panels at a predetermined, spaced-apart width.
