Abstract
A form for concrete strike-off includes a pan adapted to float on a plastic concrete surface, a rigid straightedge, and a support. The straightedge is coupled on one end to the pan and the support is coupled to the opposing end of the straightedge with the straightedge thereby defining a reference elevation for concrete strike-off operations.
Claims28
A form for concrete strike-off, comprising:
- a pan adapted to float on plastic concrete;
- a post pivotably coupled on one end thereof to said pan for rotation in at least one plane relative to said pan;
- a rigid straightedge having first and second ends opposing one another along a longitudinal dimension thereof;
- means for coupling said first end of said straightedge to said post wherein, when said post is perpendicular to said pan, said first end can be adjusted to an elevation relative to said pan;
- and
- a support coupled to said second end of said straightedge with said straightedge defining a reference elevation for concrete strike-off operations.

A form for concrete strike-off, comprising:
- a pan adapted to float on plastic concrete;
- a post pivotably coupled on one end thereof to said pan;
- a rigid straightedge having first and second ends opposing one another along a longitudinal dimension thereof;
- a rigid bracket rigidly coupled to said first end of said straightedge and loosely coupled to said post;
- means coupled to said post and cooperating with said rigid bracket for fixing said rigid bracket to a position on said post wherein said position defines an elevation of said first end relative to said pan when said post is perpendicular to said pan;
- and
- a support coupled to said second end of said straightedge with said support including means for adjusting an elevation of said second end of said straightedge thereby defining a desired height for leveling the plastic concrete.

A method of defining a reference elevation for a concrete strike-off operation, comprising the steps of:
- providing a rigid straightedge having first and second ends opposing one another along a longitudinal dimension thereof;
- supporting said first end from a first support that floats on a plastic concrete surface;
- and
- that is coupled to said first end to allow said first support to be moved to a new location on the plastic concrete, by movement of said straightedge
- supporting said second end from a second support such that said straightedge defines a reference elevation for a concrete strike-off operation.

A form for concrete strike-off, comprising:
- a first support adapted to float on plastic concrete;
- a rigid straightedge having first and second ends opposing one another along a longitudinal dimension thereof, said first end coupled to said first support;
- and
- to allow said first support to be moved to a new location on the plastic concrete, by movement of said straightedge
- a second support coupled to said second end of said straightedge with said straightedge defining a reference elevation for concrete strike-off operations.
2 more elements
A form assembly for concrete strike-off, comprising:
- first and second portable forms, each of said first and second portable forms having
- (i) a first support adapted to float on plastic concrete,
- (ii) a rigid straightedge having first and second ends opposing one another along a longitudinal dimension thereof, said first end coupled to said first support to allow said first support to be moved to a new location on the plastic concrete by movement of said straightedge, and
- (iii) a second support coupled to said second end of said straightedge with said straightedge;
- said straightedge that is associated with said first portable form, opposing and spaced apart from said straightedge that is associated with said second portable form, thereby defining a reference elevation for concrete strike-off operations.
