FIRE PREVENTION COVER AND FIRE PROTECTION CONSTRUCTION FOR BLOCK PENETRATION PART
PROBLEM TO BE SOLVED: To provide a fire prevention cover capable of easily realizing a fireproof treatment for a block penetration part and blind arrangement.SOLUTION: This invention relates to a fire prevention cover 1 installed at a block penetration part 12 formed at a partition body 11 of a building, the fire prevention cover comprises a cylindrical main body 2 with a thermal expansion characteristics inserted into and passed through the block penetration part 12 and several protrusion pieces 3 protruded out of an inner peripheral surface of the main body 2. Several protrusion pieces 3 are arranged side by side along a peripheral direction at an inner peripheral surface of the main body 2 as seen from a top plan view from one end or the other end in a longitudinal direction of the main body 2 and they are spaced apart in a longitudinal direction of the main body 2 in regard to the adjoining protrusion pieces 3 as seen from the top plan view.SELECTED DRAWING: Figure 1
【課題】区画貫通部の耐火処理及び目隠しを容易に実現可能な防火カバーを提供する。【解決手段】建築物の区画体１１に形成される区画貫通部１２に設置される防火カバー１であって、熱膨張性を有しかつ区画貫通部１２に挿通される筒状の本体２と、本体２の内周面から突き出る複数の突片３とを備える。複数の突片３は、本体２の長さ方向の一端又は他端から視る平面視において本体２の内周面を周方向に沿って並び、かつ、前記平面視で隣り合う突片３と本体２の長さ方向において間隔をあけて設けられている。【選択図】図１
