Abstract
A load relief coupling device which interconnects a lower, supporting member and an upper, supported member of a concrete forming apparatus to permit quick and easy relief of the load on the members by a formed concrete structure. The load relief coupler includes a supporting coupler member, a supported coupler member, and an inner coupler member positioned between the supporting and supported coupler member. Coacting teeth on the inner coupler member and on the supporting and supported coupler members cause the coupler to move between a loaded, expanded position and an unloaded, collapsed position upon relative pivotal movement between the inner coupler member and the two supporting and supported coupler members. A connector is provided for releasably holding the supporting coupler member and the supported coupler member at the loaded position relative to the inner coupler member in a position wherein said connecting teeth support the inner coupler member a spaced distance from the supporting coupler member and the supported coupler member a spaced distance from the inner coupler member. Release of the connector permits the supported coupler member to move toward the supporting coupler member moving the load relief coupler to its unloaded, collapsed position relieving a substantial part of the load on the supporting member.
