Title:
PIPING INSTALLING STRUCTURE, AND MANUFACTURE OF SOUND INSULATING MATERIAL AND PIPING INSTALLING STRUCTURE
Document Type and Number:
Japanese Patent JP3433390
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a piping installing structure with an excellent sound insulating effect by blocking a clearance between a trunk and a piping penetrating the trunk, and preventing the sound leaking of the upper and the lower stories and the neighboring chambers.
SOLUTION: A piping installing structure 76 furnishing a piping 63 and a trunk 62, in which the piping 63 penetrates through the through hole of the trunk 62, is provided. In this piping installing structure 76, the piping 63 is not contacted directly to the trunk 62, but fixed between the through hole of the trunk 62, a tubular clearance is formed between the piping 63 and the trunk 62, a sound insulating material 82 is contacted closely to the piping 63 and the trunk 62, and the sound insulating material 82 blocks the opening of the clearance between the piping 63 and the trunk 62, so as to reduce the noise from the clearance of the piping 63 and the trunk 62.
