Abstract:
An apparatus for forming a trench drain comprising:a) an elongated trench form for insertion into a trench along a longitudinal axis of the trench, wherein the form is comprised of at least one folding member folded along predetermined lines to define a top surface, a bottom surface, and first and second spaced apart side surfaces; b) first and second spaced apart frame rails supporting the trench form, each of the first and second frame rails comprising a horizontal portion, a transverse portion extending upwardly from the horizontal portion and a trench form engaging surface, the first frame rail abutting the first side surface of the form and the second frame rail abutting the second side surface of the form; c) a support member removably affixed to the first and second frame rails to maintain the first and second rails in a fixed position relative to each other, the support member including a first opening extending through the support member adjacent one end of the support member and a first fastener bearing surface surrounding the first opening and a second opening extending through the support member adjacent an opposite end of the support member and a second fastener bearing surface surrounding the second opening, the first and second fastener bearing surfaces of the support member being spaced above respective uppermost surfaces of the transverse portions of the first and second frame rails; and d) a first fastener bearing against the first fastener bearing surface of the support member, extending through the first opening of the support member, and releasably engaging the first frame rail and a second fastener bearing against the second fastener bearing surface of the support member, extending through the second opening of the support member, and releasably engaging the second frame rail; e) wherein said trench form is comprised of an outer form having parallel first and second side walls defining the first and second side surfaces and a bottom wall defining the bottom surface, a base form disposed in an interior region defined by the outer form, a box form disposed in the interior region defined by the outer form, the box form including a plurality of cross members extending between the first and second side walls, and a top form having a top wall defining the top surface.
