EMBEDDED MEMBER FOR CONCRETE SLAB AND BASE BOARD FOR CONCRETE SLAB HAVING EMBEDDED MEMBER, AS WELL AS STRUCTURE

摘要

PROBLEM TO BE SOLVED: To avoid formation of redundant recessed grooves and notches having no pipes P for facilities inserted therein, in a surface of an embedded member 10, and to avoid unnecessary increase in weight of a concrete slab caused by increase in amount of poured cast-in-place concrete, in construction of the concrete slab on which a number of pipes P for the facilities are laid.;SOLUTION: The plurality of notches 13, 14, 15, 16, and 17 are formed in the surface of the embedded material 10 formed of a synthetic resin foam product, and when the pipes P for the facilities are laid in the construction field, the synthetic resin foam body is partially removed by using the notches. As a result, the U-shaped recessed grooves for housing the pipes for the facilities can be formed.;COPYRIGHT: (C)2002,JPO
