PURPOSE:To facilitate assembling of frameworks for an installation line including areas for installing various installation apparatuses, to ensure setting of dimensions for the areas for installing the installation apparatuses and to standardize the installation areas. CONSTITUTION:Two finishing materials 3 for forming an installation line L, extending continuously in the longitudinal direction, are fixed with supporting metal fixtures 4 to the underside of substrate materials 1, hung down horizontally in parallel with one another from a ceiling slab S with hanging members 2, so that the finishing materials intersect the backing materials at a right angle. Engaging parts 7h on both ends of an extending material 7 in a specified dimension are put on and fixed to notches 3f provided on specified positions in the longitudinal direction of the finishing material, and an installation line L, composed at specified intervals of areas L1 for installing lighting apparatuses and areas L2 for installing other installation apparatuses, is formed in the longitudinal direction in a space between the finishing material and a counterpart finishing material 3. Thereby the installation line L for housing various installation apparatuses can be easily installed while setting of dimensions for the areas L1 for installing the lighting apparatuses and the areas L2 for installing other installation apparatuses can be ensured. |
