BUILDING CHIMNEY
To provide a building chimney that can prevent a fixed structure such as an anchor bolt at the lower end of the chimney from being damaged by an external force such as an earthquake motion, and can facilitate installation work.SOLUTION: A leg portion 20 of a building chimney 10 is fixed to a skeleton 1a of a building 1. A chimney body 11 is erected on the leg portion 20. A peripheral wall 22 is formed on the outer peripheral portion of the leg portion 20 and a receiving plate 26 is provided inside the peripheral wall 22. A lower end portion 12 of the chimney body 11 is inserted to the inside of the peripheral wall 22 and placed on the receiving plate 26. The leg portion 20 and the lower end portion 12 of the chimney body 11 are unconstrained from each other so that the chimney body 11 can be tilted and displaced upwardly relative to the leg portion 20.SELECTED DRAWING: Figure 2
【課題】地震動等の外力によって煙突下端におけるアンカーボルト等の定着構造が破損するのを防止するとともに、設置施工を容易化できる建物用煙突を提供する。【解決手段】建物1の躯体1aに建物用煙突10の脚部20を定着させる。脚部20上に煙突本体11を立設する。脚部20の外周部には周壁22を形成し、周壁22の内側に受けプレート26を設ける。煙突本体11の下端部12を周壁22の内側に差し込んで受けプレート26に載せる。脚部20と煙突本体11の下端部12とは、煙突本体11の脚部20に対する傾斜及び上方変位が許容されるように、互いに非拘束状態とする。【選択図】図2
