Abstract
A concrete forming panel with lightweight siderail includes a face plate and a frame, the frame including at least one siderail and a bushing plate coupled thereto, the bushing plate having thereon a wear member of a material having greater hardness than the bushing plate. The wear member is positioned adjacent an opening in the bushing plate, the hole being in registry with a corresponding hole in the siderail, whereby fasteners passing through the hole and opening to couple the forming panel to other structual members in a concrete forming system, such as another forming panel, will engage the wear member. The use of a wear member permits the use of lighter weight siderails and bushing plates.
Claims34
A concrete forming panel comprising:
- a face plate;
- and
- a frame coupled to said face plate and including at least one rail, said rail having an exposed edge and a face plate edge proximate the face plate, an inner surface and an outer surface and at least one hole extending therethrough and adapted to receive a coupling pin, said hole having a inner circumscribing periphery, said rail being of a first material and further including a wear element of a second material having a hardness greater than that of said first material and coupled to said rail with a majority of the wear element recessed below the inner surface and substantially positioned outboard of the periphery.
A concrete forming panel as set forth in claim 29, including a steel reinforcing member received in said channel.
A concrete forming panel comprising:
- a face plate;
- and
- a frame including at least one rail, said rail including at least one longitudinally extending hollow chamber and having a transversely extending hole through the rail adapted for receiving a coupling pin therethrough, the rail being of a first material and further including a wear element of a second, relatively harder material coupled to said rail proximate to said hole whereby a portion of said wear element is exposed in pin engaging relationship to said hole.
