Crossing in the foundation material device null hanging channel string

摘要

PROBLEM TO BE SOLVED: To provide a robust substrate material device for construction of a suspended ceiling and a wall surface, which facilitates construction, and eliminates waste of a material for reducing costs.;SOLUTION: A substrate material for the formation of the suspended ceiling and the wall surface is formed by hooking a single ceiling joist and a double ceiling joist twice as wide as the single ceiling joist as a clip in such a manner that they cross a hanging channel row. In the substrate material, a clip hooking port of the double ceiling joist is narrowed in such a manner as to be as wide as a hooking port of the single ceiling joist; the hooking port is formed in close vicinity to a lateral plate on one side; and the other side lateral plate of the double ceiling joist is protruded to the outside of a hanging channel end. Thus, the substrate material device for the construction of the suspended ceiling and the wall surface abuts on the vertical wall surface.;COPYRIGHT: (C)2010,JPO&INPIT
