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

Since the installation structure of the PC slab according to the present invention is located and hidden in the setback space between the pair of adjacent ribs, no separate caulking work or finishing work is required at the joint part, And when the PC slabs are arranged continuously, the same pair of rib patterns are repeated at predetermined intervals while hiding the joint portions of the PC slabs, which is advantageous in that the construction finishing effect is excellent.
