Document Type and Number:
Japanese Patent JP2018028337
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a structure capable of easily closing a gap around a penetration portion of a penetration pipe which penetrates a component of a floor and the like of a building, and capable of securing heat insulating performance and airtight performance irrespective of skills of an operator.SOLUTION: A gap 13a around a penetration portion 2c of a penetration pipe 2 for penetrating a component 10 of a building is closed by a closing member 20. The closing member 20 include a first layer and a third layer 21, 23 which are airtight, and a second layer 22 which is heat insulating. A pipe insertion hole 20c is formed by penetrating in a lamination direction of the first to third layers 21, 22, 23. The penetration pipe 2 is inserted in the pipe insertion hole 20c. The diameters of the pipe insertion holes 21c, 23c in the first, third layers 21, 23 are made to be smaller than the external diameter of the penetration pipe 2, and also they are made to be smaller than the pipe insertion hole 22c in the second layer 22.SELECTED DRAWING: Figure 1
