EARTHQUAKE STRENGTHENING METAL FITTING FOR CEILING, CEILING EARTHQUAKE PROOF FRAMEWORK, AND CEILING USING THEM

摘要

PROBLEM TO BE SOLVED: To provide: an earthquake strengthening metal fitting for a ceiling, which can connect a brace material to a hanging metal fitting in a simple and compact structure for all ceiling backing materials gathering at each intersection, and improves aseismic performance; a ceiling earthquake proof framework using the earthquake strengthening metal fittings for a ceiling; and a ceiling using them.;SOLUTION: Each of earthquake strengthening metal fittings for a ceiling 1a-1d includes: a hanging metal fitting mounting part 7 mounted in surface contact with a side face of a hanging meal fitting 6; a backing material fixing part 8 fixed to one of ceiling backing materials 2a, 2b; and a reinforcing surface part 9 to which the brace material is connected and which connects the hanging metal fitting mounting part 7 to the backing material fixing part 8. All ceiling backing materials 2a, 2b gathering at an intersection 14 can be connected to the hanging meal fitting 6. A ceiling earthquake proof framework is constituted of a ceiling lattice frame 3, a hanging bolt 5, and a brace material 4 with the earthquake strengthening metal fittings for the ceiling 1a-1d attached. A hanging ceiling is provided with the earthquake strengthening metal fittings for the ceiling 1a-1d or the ceiling earthquake proof framework.;COPYRIGHT: (C)2015,JPO&INPIT
