FIRE RESISTANT STRUCTURE, FIRE RESISTANT IMPLEMENT AND BLOCKING MEMBER
To provide a fire resistant structure more reliably blocking a penetration part of a fireproof compartment.SOLUTION: A fire resistant structure is such that: a wiring/piping material is inserted into a penetration part penetrating a fireproof compartment of a building in an axial direction; and a fire resistant implement is installed between the inner peripheral surface of the penetration part and the outer peripheral surface of the wiring/piping material. The fire resistant implement includes: a fire resistant implement body made from heat expansion material expanded due to heat, fixed to the inside of the penetration part, and surrounding the outer peripheral surface of the wiring/piping material with a prescribed clearance; and a blocking member compressively deformed so as to block the clearance between the fire resistant implement and the wiring/piping material by internally inserting the wiring/piping material. The blocking member is provided with a plurality of groove parts splitting the inner peripheral part of the blocking member facing the outer peripheral surface of the wiring/piping material into a plurality of split pieces in a circumferential direction. The plurality of split pieces are compressively deformed in each other individually in the circumferential direction and closely contact to the outer peripheral surface of the 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、熱により膨張する熱膨張性材料からなり、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
