PC Precast Concrete hollow core slab by extrusion

机译:PC预制混凝土空心板挤压成型

摘要

The present invention provides a PC hollow slab reinforced with a shear reinforcement manufactured by an extrusion molding method in which a CFRP sheet is fixed to a side end portion of a hollow slab body and an end portion of the hollow portion to improve the abdominal shear strength at the end portion. The PC hollow slab, which is manufactured by the extrusion molding method according to a preferred embodiment of the present invention and is reinforced by shearing, is made of precast concrete, and hollow slabs, which are open at both ends and hollow portions formed in the longitudinal direction, A body; A tensile member arranged in the hollow slab body in the longitudinal direction at regular intervals and arranged in the width direction to introduce compressive stress to the lower portion of the neutral axis of the hollow slab body; And a CFRP sheet for laminating and bonding the side surfaces of the hollow slab body by adjusting the number of layers of the CFRP sheet by means of an epoxy adhesive at certain intervals from both ends of both side surfaces of the hollow slab body.
