Abstract:
1. A transportable multi-stemmed pre-stressed concrete floor system for manufactured buildings comprising, in combination: a pair of multi-stemmed concrete floors with each multi-stemmed floor having a generally rectangular configuration with an up side and a down side and a thickness there between, each multi-stemmed floor having two parallel side edges and two parallel end edges, one end edge being the front end and one end edge being the rear end, with each multi-stemmed floor having a downwardly disposed short front diaphragm header and a parallel downwardly disposed rear diaphragm header and a plurality of long downwardly disposed stems there between, all stems of each multi-stemmed floor being perpendicular to the diaphragm headers and all stems having a pair of stressing cables running the length of the stems and through the front diaphragm header and through the rear diaphragm header, with two of the stems of each multi-stemmed floor being located on and contiguous with the side edges of the multi-stemmed floor and forming the edges of each multi-stemmed floor, the side edge of a multi-stemmed floor being configured to contact the side edge of another multi-stemmed floor to form a floor system, the stems of each multi-stemmed floor comprising inner stems and edge stems, the inner stems being between the two edge stems, the front inner stems each having a plurality of fifth wheel coupling bolt holes there through, the rear inner stems that are adjacent the side edge stems each have a plurality of suspension shackle mounting holes there through; a wheel assembly having plurality of rigid metallic suspension shackle mounting plates with each having a squared U-shaped configuration with each plate receiving and snugly fitting the downwardly projecting stem of the multi-stemmed floor, each of the plates having a bolt hole there through with the bolt hole being align-able with the suspension shackle mounting bolt holes of the stems that are adjacent to the rear edge and side edge of the multi-stemmed floor, a wheel assembly being couple-able to the stems and having a plurality of axles with a plurality of wheels being rotatably coupled to each of the axles, with each axle being coupled to a pair of parallel suspension springs and each suspension spring being coupled to one of a pair of suspension carrying plates, the suspension carrying plate being coupled to a plurality of suspension shackle mounting plates, allowing the wheel assembly to be removably coupled to the multi-stemmed floor to allow the multi-stemmed floor to be trailed with a minimal road clearance sufficient to be used on all roadways without restriction; a fifth wheel subassembly having a hitching portion for release-able attachment to a trailer hitch and an attachment portion for coupling with a multi-stemmed floor, the attachment portion having a plurality of rearward extending carrier beams, with each carrier beam having a plurality of rigid metallic suspension shackle mounting plates with each shackle mounting plate having a squared U-shaped configuration with each plate receiving and snugly fitting the downwardly projecting stem of the multi-stemmed floor, each of the mounting plates having a bolt hole there through with the bolt hole being align-able with the fifth wheel coupling bolt holes of the front inner stems of the multi-stemmed floor, allowing the fifth wheel subassembly to be removably coupled to the multi-stemmed floor to allow the floor to be trailed with a minimal road clearance sufficient to be used on all roadways without restriction; and a plurality of bolts to couple the multi-stemmed floor to the wheel assembly and the fifth wheel subassembly, thereby allowing the multi-stemmed floor to be pulled from one location to another with ease and safely.
