JOIST MEMBER AND CEILING STRUCTURE
To provide a joist member capable of steadily reducing noise caused by vibration transmitting from a room on an upper floor of a building to a room on a lower floor without increasing additional parts and working load upon installation.SOLUTION: A joist member is provided with: a first flange 10A and a second flange 10B oppositely arranged in a direction orthogonal to a longitudinal direction viewing from the longitudinal direction; and a web 10C connecting an end of one side of the first flange 10A to an end of one side of the second flange 10B. Further, one part of the second flange 10B passing through an end of the other side of the first flange 10A viewing from the longitudinal direction and positioned on an opposite side of the web 10C with respect to a reference line L parallelly extending with the web 10C is a load applied point P on which gravity and inertia force acting on a ceiling surface member 12 is applied.SELECTED DRAWING: Figure 3
【課題】部材数および施工時の手間の増加を招くことなく、建物の上階の部屋から下階の部屋へ伝わる振動に起因する騒音を安定的に低減することができる根太材を提供する。【解決手段】根太材は、長手方向から見て長手方向と直交する方向に対向して配置された第１フランジ部１０Ａ及び第２フランジ部１０Ｂと、第１フランジ部１０Ａの一方側の端と第２フランジ部１０Ｂの一方側の端とをつなぐウェブ部１０Ｃと、を備えている。また、長手方向から見て第１フランジ部１０Ａの他方側の端を通りかつウェブ部１０Ｃと平行に延びる基準線Ｌに対してウェブ部１０Ｃとは反対側に位置する第２フランジ部１０Ｂの一部分が、天井面材１２に作用する重力及び慣性力が入力される荷重入力点Ｐとなっている。【選択図】図３
