Title:
PIPE JOINT STRUCTURE, PIPING STRUCTURE AND BUILDING
Document Type and Number:
Japanese Patent JP2016142003
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance sound insulation and vibration resistance, in order to reduce vibration transmission to a building.SOLUTION: The present invention relates to a pipe joint structure having a resin pipe joint 7 inserted into a slab penetrating hole 15 formed through a floor slab 3, and the resin pipe joint 7 has a thermally expanding fireproof material layer 16, at least in a location inside the slab penetrating hole 15. An outer peripheral part of the thermally expanding fireproof material layer 16 of the resin pipe joint 7 is covered with a sound insulating vibration resistant sheet 41, and a top edge part of the sound insulating vibration resistant sheet 41 protrudes above a top edge part of the slab penetrating hole 15. The sound insulating vibration resistant sheet 41 is of a multi-layer structure, with an inorganic fiber layer 42 on inside and a modified asphalt layer 43 on outside.SELECTED DRAWING: Figure 3
