half-slab of the present invention relates to using prefabricated building structures on the external wall of the , and these wire or rod that binds to one of the blocks are combined to penetrate the corner walls, and the roof center reinforcement for reinforcing the joint areas be provided in the central joint part of the half-slabs pair of roof, a half roof slab and external Roof to reinforce the joint region be provided on the connection of both ends of the reinforcing wall portion is provided. Thus, the liner or the outer wall by a steel bar, corner walls are so bound into a single block side structure of the building structure becomes very robust, vulnerable parts of the roof damage along the seam area in the center of the stress concentration hayeoseo reinforced Salo roof reinforcement sikimyeo prevention, hayeoseo fastening hole in the roof to form a reinforcing steel bar fastened to buy part of the roof and tighten the lock nut and the joint portion of the roof the roof is rigidly coupled. And, since the upper end of the outer wall and a corner wall contact surface to the bottom surface of the half-slab roof placed obliquely half slab is stable and supported on the outer wall and a corner wall for the roof, they are cohesive so signed by the insert and the roof fastening bolt is maximized. ;
