FIRE PROTECTION COVER AND FIRE PROTECTION CONSTRUCTION OF COMPARTMENT THROUGH-HOLE
PROBLEM TO BE SOLVED: To provide a fire protection cover and a fire protection construction using the fire protection cover capable of exhibiting excellent fire protection performance without using a fireproof putty to the utmost, and easy to be constructed to a through-hole formed in a compartment body of a building.SOLUTION: A fire protection cover 1 is formed in a compartment body 11 of a building and installed to a through-hole 12 into which at least one tube body 13 is inserted, and is used for protecting the through-hole 12 from fire. The fire protection cover 1 has thermal expansion property and includes a cylindrical body part 2 inserted to the through-hole 12. The body part 2 is provided with a projection 4 projecting inwardly from the inner peripheral surface of the body part 2 at one end side of the axial direction, and receives a fireproof putty 5 filled from an opening 21 on one end side of the body part 2 on a surface 40 of the projection 4.SELECTED DRAWING: Figure 1
【課題】耐火パテを極力使用しなくても良好な防火性能を発現でき、かつ、建築物の区画体に形成された貫通孔への施工が簡易な防火カバー及び当該防火カバーを用いた防火構造を提供する。【解決手段】防火カバー１は、建築物の区画体１１に形成されかつ少なくとも１本の管体１３が挿通される貫通孔１２に設置され、貫通孔１２の防火に用いられる。防火カバー１は、熱膨張性を有し、貫通孔１２に挿通される筒状の本体部２を備える。本体部２は、軸方向の一端側に、本体部２の内周面から内側に向けて突き出た突出部４が設けられ、突出部４の表面４０で本体部２の一端側の開口２１から充填される耐火パテ５を受け止める。【選択図】図１
