FIREPROOF STRUCTURE OF COMPARTMENT PENETRATION PART
To obtain a fireproof structure of a compartment penetration part capable of reliably preventing a fire from being spread by a simple structure since a penetration part between compartments being important in safety in a building is required to have a structure of preventing the fire from being spread to other compartments when the fire breaks out in any compartment.SOLUTION: A fireproof structure of a compartment penetration part includes: a bus duct 11 penetrating through an opening NP provided at a compartment penetration part SP formed in a fire resistant partition wall 14 of a building, and having a communication area SR extending from one side to the other side of the fire resistant partition wall 14 in the inside in response to an inner face of the opening NP; and a bus bar 12 extending through the communication area SR along the axis line in the inside of the bus duct 11. A sealing member FS constituted of a resin-molded partition 20 comprising a fire retarding material or an incombustible material for closing an outer circumferential surface of the bus bar 12 and an inner circumferential surface of the bus duct 11 and inhibiting communication from one side to the other side of the fire resistant partition wall 14 is provided in the communication area SR.SELECTED DRAWING: Figure 1
【課題】建築物における安全上重要な区画間の貫通部は、いずれかの区画で火災が発生した際に、他の区画への延焼を防止する構造とすることが要求されている。簡単な構造で、確実に延焼を防止できる区画貫通部の耐火構造を得る。【解決手段】建築物の耐火用仕切り壁１４に形成された区画貫通部ＳＰに設けられる開口部ＮＰを貫通し開口部ＮＰの内面に対応して内部に耐火用仕切り壁１４の一側から他側に及ぶ連通領域ＳＲを有するバスダクト１１と、バスダクト１１の内部でその軸線に沿い連通領域ＳＲを通って延在するバスバー１２を備え、連通領域ＳＲにおいてバスバー１２の外周面とバスダクト１１の内周面とを封塞し耐火用仕切り壁１４の一側から他側への連通を阻止する難燃材または不燃材からなる樹脂成型物の仕切り２０で構成される封塞部材ＦＳを設けた。【選択図】図１
