INSTALLATION DEVICE FOR ELECTRIC AIR-CONDITIONING DUCT IN HOLLOW SLAB

摘要

PURPOSE:To permit the compact and simple installation of an electric duct and an air-conditioning duct in a small space as well as the increase of the ceiling height of respective floors as much as possible by a method wherein the electric duct and the air-conditioning duct are provided in a hollow slab along the continuous direction of the hollow sections thereof so that the electric duct is piled upon the air-conditioning duct in up-and-down relation. CONSTITUTION:An electric duct 6 is provided so as to be piled upon an air-conditioning duct 5 in up-and-down relation along the continuous direction of the hollow section 4 of a hollow slab A, made by the floor form of a PC board 1 and poured concrete. The air-conditioning duct 5 is formed by a metallic plate such as a galvanized iron sheet or the like so as to have an oblong channel section opened downward immediately and a cushioning plate 9, consisting of a soft plate such as Styrofoam plate or the like, is provided on the air-conditioning duct 5 while the electric duct 6 is provided o the air-conditioning duct 5 along the lengthwise direction thereof. The electric duct 6 is formed by a metallic plate such as the galvanized iron sheet or the like same as the air-conditioning duct 6 so as to have an oblong rectangular section while the section is divided into plural section in the widthwise direction thereof by providing partitioning plates 6a therein.
