FIXING METAL FITTING FOR CEILING JOIST RECEIVER
PROBLEM TO BE SOLVED: To provide a fixing metal fitting 6 for a ceiling joist receiver having small height and width that may be installed without an upper nut 21 protruding from a top surface of a ceiling joist receiver 3, thereby enabling the ceiling joist receiver 3 to be fixed on a bottom edge of a hanging bolt even on a ceiling substrate structure in a narrow ceiling space, regardless of whether existing or new, at the same time functioning as a tilting restriction surface that prevents significant widening and deformation of a side surface of the ceiling joist receiver 3 by a hanging bolt fixing part 62, thus enhancing aseismatic resistance of the structure.SOLUTION: A fixing metal fitting 6 for a ceiling joist receiver is installed integrally and next to each other with a ceiling joist receiver fitting/fixing part 61 on a side and a hanging bolt fixing part 62 on the other side, with a side surface piece 6a abutted on the side surface of the ceiling joist receiver interposed in between, the ceiling joist fitting/fixing part being formed in a U-shape when seen from sideways, and the hanging bolt fixing part being formed by bending into an L-shape for having a bottom end side of a hanging bolt 2 fixed with a nut thereon. The hanging bolt fixing part 62 is configured such that an upper nut 21 may be installed within a side surface region having same height and a width as the ceiling joist receiver 3.SELECTED DRAWING: Figure 5
【課題】野縁受け固定金具６の高さ幅を短く形成して、上側ナット２１を野縁受け３の上面から突出しない状態で配設できるようにし、天井スペースの狭い天井下地構造であっても、新設、既設を問わず吊りボルトの下端部に野縁受け３を固定することができ、野縁受け３の側面を吊りボルト固定部６２が大きく拡開変形してしまうことを規制する傾動規制面として機能させ、その耐震性を向上する。【解決手段】野縁受け固定金具６を、野縁受けの側面に面当てされる側面片６ａを介して、その一側に、側面視コ字状に形成せしめた野縁受け嵌装固定部６１と、その他側に、吊りボルト２の下端部側をナット固定されるＬ字状に折曲形成せしめた吊りボルト固定部６２とを備えて一体に並設せしめ、吊りボルト固定部６２を、上側ナット２１が野縁受け３の高さ幅となる側面領域内に配設可能に構成する。【選択図】 図５
