Abstract

A metal bar has upturned end flanges on opposite ends of a base portion arranged to provide stops against the outward movement of a pair of vertical form panels resting on the clip. Spaced inwardly from said end flanges is a pair of outwardly directed tongues struck out from said base portion in inclined positions with elevated ends spaced from said flanges. The form panels are received in the spaces between the end flanges and the tongues. Panels improperly placed in the mid portion of the clip may be readily pushed out against the end flanges or the pouring of the concrete will push the panels out to their proper positions. The tongues provide sloping ramp surfaces to facilitate the outward movement of the panels. The clip is also utilized in making forms for the monolithic pouring of a wall and footing. In one embodiment the clip is mounted on stakes in the footing pour area to support the wall form panels. In another embodiment in similar arrangement the clips are made long enough for mounting on the top edges of the footing form panels.

Claims

1. A concrete form clip comprising a metal bar having upturned end flanges perpendicular to an intermediate base portion, and a pair of inclined tongues directed outwardly and upwardly from said base portion toward said end flanges, each tongue having a free end elevated above said base portion and opposed to one of said end flanges at a distance therefrom to receive a form panel in the space between said flange and the end of the tongue, said tongues providing sloping ramp surfaces for sliding movement of the panels on the tongues outward from the middle part of said base portion into said spaces between said end flanges and the ends of the tongues.

2. A clip as defined in claim 1, each tongue forming an inclined strut to maintain a near perpendicular angular relationship between said panel and said base portion of the clip whereby a bottom clip on a bottom edge of a panel will hold the panel upright, and whereby an inverted top clip on a top edge of an upright panel will be held in outstanding position from the panel.

3. A clip as defined in claim 1 wherein said tongues are struck out from said base portion leaving holes between said flanges and the end portions of the tongues which are connected to said base portion of the clip.

4. A clip as defined in claim 3, said holes acting as receivers for the tops of stakes or posts inserted in said holes and said tongues covering said holes and acting as stops for the top ends of said stakes or posts.

5. A clip as defined in claim 1 supporting a pair of wall form panels, means supporting said clips and wall form panels in elevated position above the ground level, and a pair of footing form panels at a distance on opposite sides of said wall form panels, for pouring a monolithic wall and footing.

6. A clip as defined in claim 1 mounted at its ends on a pair of footing form panels, said first form panels being wall form panels supported on said clip in positions inward from said footing form panels, and a pair of spacers on said clip between said end flanges and said wall form panels, for pouring a monolithic wall and footing.

7. The invention defined in claim 6, said spacers closing the spaces between said footing form panels and said wall form panels to prevent concrete overflowing said footing form panels.

8. A form as defined in claim 5, said supporting means comprising stakes or posts.

9. A clip as defined in Claim 1 supporting a pair of wall form panels, and a pair of footing form panels at a distance on opposite sides of said wall form panels supporting said clips and wall form panels in elevated position above the ground level.
