INSTALLATION STRUCTURE OF PRECAST CONCRETE SLAB HAVING ITS CONNECTION PART BEING CONCEALED BY COUPLED RIBS AND, MANUFACTURING METHODS OF THE PRECAST CONCRETE SLAB

摘要

According to the present invention, an installation structure of a PC slab does not require additional caulking work or finishing work in a connecting portion as the connection part between PC slabs is concealed by being located in a setback space between a pair of adjoining ribs; maintenance control of cracks and spots due to water leakage can easily be executed; and an excellent construction finishing effect is left as a pair of identical rib patterns are repeated at a certain space while concealing a connecting portion of the PC slab.
