The present invention is to provide a lower half-cross-section concrete slab to construct safely and cheaply by installing a truss reinforcing bar to which the compressive force is provided to fabricate the lower half cross-section concrete slab of the bottom and by removing a supporting post, and a fabrication and construction method thereof. Moreover, the construction method of the lower half-section concrete slab according to the present invention for achieving the objective is configured to dispose a plurality of the lower half-section concrete slabs on a girder, to form a loop connection portion between the lower half-section concrete slabs, and to install a shear distributing reinforcing bar in the loop connection portion, and to construct a bridge slab in the lower half-section concrete slabs. |
