ABSTRACT:
A concrete form having a frame with a first pair of outer frame members and a second pair of outer frame members. The first pair of outer frame members are disposed perpendicular to the second pair of outer frame members so that the first and second pairs of outer frame members define a substantially rectangular shape. The concrete form has two inner frame members connected between two of the outer frame members, the inner frame members being spaced to define a rectangular bay area therebetween. The concrete form has a flat concrete-forming member fixed to the outer frame, and a support member with a pair of end portions and a middle portion disposed between the end portions. The support member is connected to the first and second inner frame members so that the middle portion of the support member is spaced from the concrete-forming member by a first distance and so that the end portions of the support member are spaced from the concrete-forming member by a second distance smaller than the first distance.
