BUILDING CEILING STRUCTURE
PROBLEM TO BE SOLVED: To provide a ceiling structure capable of reducing heavy floor impact without increasing the risk of falling off of a ceiling board, which can be efficiently constructed.SOLUTION: The ceiling structure is provided with a TMD (tuned mass damper) (16) to a ceiling joist (12) of an under-layer ceiling backing material (6) to thereby reduce a heavy floor impact which is generated when a heavy matter impacts on an upper-layer floor structure (4). The TDM includes: a spring member (18) bridged across a pair of neighboring ceiling joists; and a weight member (20) attached to the spring member in an intermediate part. Since the TMD is not directly attached to a ceiling board but attached to the ceiling joist, the risk of falling off of the ceiling board is not increased. Also, since the TMD has a structure to be bridged across a pair of neighboring ceiling joists, the TMD can be easily installed.SELECTED DRAWING: Figure 2
【課題】天井ボードの落下のリスクを増大させずに、重量床衝撃音を低減でき、効率良く施工できる天井構造を提供する。【解決手段】下層階の天井下地材（６）の野縁（１２）にＴＭＤ（１６）を取り付けることにより、上層階の床構造（４）に重量物が衝突した場合に発生する重量床衝撃音を低減する。ＴＤＭは、隣接する１対の野縁間に架け渡されたばね部材（１８）と、ばね部材の中間部に取り付けられた錘部材（２０）とを有する。ＴＭＤが、直接天井ボードに取り付けられるのではなく、野縁に取り付けられているため、天井ボードの落下のリスクが増大していない。また、隣接する１対の野縁間にＴＭＤを架け渡す構造であるため、施工の手間が少ない。【選択図】図２
