PRECAST CONCRETE SLAB, PRECAST CONCRETE SLAB STRUCTURE USING JOINT BLOCK, AND CONSTRUCTION METHOD AND REPAIR METHOD FOR PRECAST CONCRETE SLAB STRUCTURE

摘要

The present invention relates to a precast concrete slab, a precast concrete slab structure using a joint block, and a construction method and a repair method for a precast concrete slab structure. PC slabs are assembled and connected to each other on an upper part of a lower ground in the PC slab structure. Each of the PC slabs has a plurality of dowel bars opened to the upper part having a predetermined length, and the plurality of dowel bars installed at fixated intervals on a side. The PC slabs are in contact with each other by corresponding to a position in which a dowel bar pocket is formed. A site grouting space is formed by the dowel bar pocket. Mortar is injected into the site grouting space while the dowel bar is installed in the site grouting space, thus a joint block is formed and the PC slab connected.;COPYRIGHT KIPO 2017
