CHIMNEY FOR BUILDING
PROBLEM TO BE SOLVED: To provide a chimney for a building of easily returning to an original attitude, when an earthquake settles, by restraining smoke leakage by lateral dislocation, when horizontal force acts in the earthquake.SOLUTION: A plurality of cylindrical chimney units 11 of a chimney 10 for a building are vertically laminated in a row. A joint part 20 is provided between mutual vertically adjacent two chimney units 11U and 11L. The mutual two chimney units 11U and 11L are linked in a sliding node point state so as to allow very small rotation by regulating lateral dislocation to the lower side chimney unit 11L of the upper side chimney unit 11U by the joint part 20. A side arm 31 is projected from a side part of the respective chimney units 11, and is held by a skeleton 1a of a building 1. The side arm 31 is upwardly displaceably restricted to the skeleton 1a by an arm restriction part 32.SELECTED DRAWING: Figure 1
【課題】地震時の水平力が作用した際、横ずれ等による漏煙を抑制し、かつ地震が収まったときは元の姿勢に戻りやすい建物用煙突を提供する。【解決手段】建物用煙突１０の筒形状の複数の煙突ユニット１１を上下へ一列に積層する。上下に隣接する２つの煙突ユニット１１Ｕ，１１Ｌどうし間にジョイント部２０を設ける。このジョイント部２０によって、上側の煙突ユニット１１Ｕの下側の煙突ユニット１１Ｌに対する横ずれを規制し微小回転を許容するように、２つの煙突ユニット１１Ｕ，１１Ｌどうしを滑節点状態で連接する。各煙突ユニット１１の側部から側方アーム３１を突出させて建物１の躯体１ａに保持させる。アーム拘束部３２によって、側方アーム３１を躯体１ａに対して上方変位可能に拘束する。【選択図】図１
