Abstract:
A removable support structure for supporting a wet concrete pour and cure during concrete slab construction, said slab disposed between permanently disposed building girders and columns, said removable support structure comprising:(a) shoring girders, each said shoring girder having a first and second end; (b) first latch engaging means, said first latch engaging means for removably engaging at least one of said first and second ends of each said shoring girder to a respective first one of either said building girders or columns, said shoring girders for extending from said respective first one of either said building girders or columns to a respective second one of either said building girders or columns, to which said second end of said shoring girder is to be engaged, said first latch engaging means having means for being extended or retracted a spaced distance from or towards said at least one of said first and second ends of each said shoring girders; (c) shoring beams, each said shoring beam having a third and fourth end; (d) second latch engaging means, said second latch engaging means for removably engaging at least one of said third and fourth ends of each said shoring beam to a respective shoring girder, each said second latch engaging means including means for being extended or retracted a spaced distance from or toward said at least one of said third and fourth ends of each said shoring; (e) a plurality of deck members for supporting the wet concrete until it hardens, each of said deck members for being positioned between said respective first one of either said building girders or columns and said respective shoring beam, or between said respective shoring beam and said respective second one of either said building girders or columns, each said deck member having a fifth and sixth end, each said deck member for being supported at said fifth end by said respective first or second one of said building girders or columns and at said sixth end by said respective shoring beam; (f) first cooperating means for being disposed between said fifth end of each said deck member and said respective first or second one of said building girders or columns and for detachably engaging said fifth end to said respective first or second one of said building girders or columns each said first cooperating means for detachably engaging including means for permitting rotation of said respective deck member downward, to facilitate removal of each said deck member; and, (g) second cooperating means disposed at said sixth end of each said deck member, said second cooperating means including means cooperatively engaging each said sixth end of respective deck members, said second cooperating means further including means utilized by an operator to initiate downward rotational movement of each said deck member at said sixth end, to facilitate removal of said sixth end from the concrete after it hardens; said first and second latch engaging means and said first and second cooperating means permitting rapid engagement and/or subsequent rapid removal of the elements of said support structure, before the pouring of the wet concrete and after the hardening thereof, respectively, and thereafter the reuse of said support structure elements to support a subsequent concrete slab construction.
