THROUGH-HOLE COVER, AND FIRE PROTECTION CONSTRUCTION OF COMPARTMENT THROUGH-HOLE
PROBLEM TO BE SOLVED: To provide a through-hole cover capable of easily performing fireproof treatment of a compartment through-hole.SOLUTION: A through-hole cover 1 is inserted into a through-hole 12 of a compartment body 11 and includes a main body 2 and fin parts 4a,4b. The main body 2 has a cylindrical shape and a wiring or piping is inserted thereto. The fin parts 4a,4b are provided inside of the main body 2 at one end or the other end in the longitudinal direction of the main body 2. The fin parts 4a,4b are formed from a plurality of projection pieces 6 arranged in the circumferential direction of the inner peripheral surface of the main body 2. The plurality of projection pieces 6 project to a radial inner side from the inner peripheral surface of the main body 2. The periphery of a wiring or piping is surrounded by tips of the plurality of projection pieces 6. The main body 2 and the plurality of the projection pieces 6 forming the fin parts 4a,4b have thermal expansion property.SELECTED DRAWING: Figure 1
【課題】区画貫通孔の耐火処理を容易に実現可能な貫通孔カバーを提供する。【解決手段】本発明の貫通孔カバー１は、区画体１１の貫通孔１２に挿入されるものであって、本体２と、ヒレ部４ａ，４ｂとを備える。本体２は、筒状を呈し、配線あるいは配管が内挿される。ヒレ部４ａ，４ｂは、本体２の長手方向の一端や他端において、本体２の内部に設けられる。ヒレ部４ａ，４ｂは、本体２の内周面の周方向に並ぶ複数の突出片６から構成される。複数の突出片６は、本体２の内周面から径内側に突出しており、当該複数の突出片６の先端によって、配線あるいは配管の周囲が囲まれる。本体２や、ヒレ部４ａ，４ｂを構成する複数の突出片６は、熱膨張性を有する。【選択図】図１
