EARTHQUAKE RESISTANT REINFORCEMENT METAL FITTING OF CEILING JOIST

NOSHIGE AKIHIKO / YAOITA JUN / MAEKAWA SHINYA

PROBLEM TO BE SOLVED: To provide an earthquake resistant reinforcement metal fitting of a ceiling joist capable of improving earthquake resistant strength by reinforcing its support receiving structure, by enhancing rigidity strength of a ceiling joist itself installed by a ceiling joint fixture of a structure for supporting-receiving by placing the ceiling joist in a suspending-holding shape, in a ceiling backing of requiring earthquake resistance.SOLUTION: An earthquake resistant reinforcement metal fitting is: integrally formed of ceiling joist fitted parts 71 each formed in a downward U shape and extension fixing pieces 72 each extended from a side surface piece 712 on one side to a ceiling joist supporting-receiving part 512 on the other side through an undersurface area of a ceiling joist receiver 3; and abutted onto a ceiling joist receiving-installing part 511 as a set, with each of the extension fixing pieces 72 fixed to the overlapped side surface piece 712 on the other side with a machine screw.SELECTED DRAWING: Figure 4

【課題】耐震性が求められる天井下地において、野縁を吊持ち状に載置して支持受けする構造の野縁固定金具によって取り付けられた野縁自体の剛性強度を高め、その支持受け構造を補強して耐震強度を向上することのできる野縁の耐震補強金具を提供する。【解決手段】耐震補強金具を、下向きコ字状に形成された野縁被嵌部７１と、一方の側面片７１２から野縁受け３の下面域を通過して、他方の野縁支持受け部５１２側に延出せしめた延出固定片７２とで一体形成し、組みとして野縁受け取付け部５１１に互いにスライド当接することで、延出固定片７２を他方の側面片７１２に重合せしめてビス固定する。【選択図】図４
