FIRE RESISTANT STRUCTURE, FIRE RESISTANT TOOL AND CLOSING MEMBER
To provide fire resistant grooves for more surely closing a penetration part of a fire resistant compartment.SOLUTION: In a fire resistant structure, electric wiring/piping material is inserted into a penetration part formed by penetrating a fire compartment in an architectural structure in an axial direction, and fire resistant tool is disposed between an inner peripheral surface of the penetration part and an outer peripheral surface of the electric wiring/piping material. The fire resistant tool is made of a non-thermal expansive flame-retardant material, is fixed in the penetration part, and comprises a fire resistant tool body surrounding the outer peripheral surface of the electric wiring/piping material with a prescribed interval, and a thermal expansive closing member inserted with the electric wiring/piping material, thereby, compressed and deformed so as to close a gap between the fire resistant tool and the electric wiring/piping material. The closing member comprises a plurality of groove parts that divide an inner peripheral part of the closing member facing the outer peripheral surface of the electric wiring/piping material into a plurality of divided pieces in a circumferential direction, and the plurality of divided pieces are mutually independently compressed and deformed in a circumferential direction so as to contact closely with the outer peripheral surface of the electric wiring/piping material.SELECTED DRAWING: Figure 2
【課題】本発明の目的は、より確実に防火区画体の貫通部を閉塞する耐火構を提供することにある。【解決手段】本発明の耐火構造は、建築物の防火区画体を軸方向に貫通して形成された貫通部に配線・配管材が挿通され、貫通部の内周面と配線・配管材の外周面との間に耐火具が設けられてなる。耐火具は、非熱膨張性の難燃材料からなり、貫通部内に固定され、配線・配管材の外周面を所定の間隙を空けて包囲する耐火具本体と、配線・配管材を内挿して耐火具本体と配線・配管材との間隙を閉塞するように圧縮変形した熱膨張性の閉塞部材と、を備える。閉塞部材は、配線・配管材の外周面と対面する閉塞部材の内周部を周方向において複数の分割片に分割する複数の溝部を備え、複数の分割片が周方向において互いに個別的に圧縮変形して配線・配管材の外周面に密着している。【選択図】図２
