DRAIN PIPING STRUCTURE
PROBLEM TO BE SOLVED: To prevent flame and smoke from passing through a pipe conduit by closing the same when fire occurs.SOLUTION: A drain pipe joint is made of a non-fireproof material. For the purpose of being used in a building, the drain pipe joint has: a pipe body 11 which is arranged in a through hole 7 on a floor slab 2; an upper vertical pipe connection section 6a which is extended above the floor slab and connected to a vertical drain pipe 5 where wastewater from an upper floor inflows therethrough; a lower vertical pipe connection section 6b which is extended beneath the floor slab and connected to the vertical drain pipe 5 where the wastewater flows down therethrough; and a horizontal branch pipe connection section 12 which is connected to a horizontal branch drain pipe above the floor slab. For the purpose of being used in the building, the drain pipe joint is provided with a thermally expandable fireproof material 9 at a portion of the pipe body to be embedded in the through hole on the floor slab.SELECTED DRAWING: Figure 4
【課題】火災時にその管路を閉塞し、火炎、煙等が流通しないようにする。【解決手段】排水配管継手は、非耐火性材料で形成され、建築物に施工された際に、床スラブ２の貫通孔７に配される管本体１１、床スラブの上方に突出し上階からの排水を流入させる排水立管５を接続する上立管接続部６ａ、床スラブの下方に突出し下階に排水を流下させる排水立管５に接続する下立管接続部６ｂ、および床スラブの上方で排水横枝管と接続される横枝管接続部１２を備え、建築物に施工された際に管本体における床スラブの貫通孔に対応する位置に熱膨張性耐火材９が埋設されている。【選択図】図４
