SOUND INSULATING PARTITION PANEL AND SOUND INSULATING PARTITION WALL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide partition wall structure obtaining high sound insulating performance with easy work execution and a sound insulating partition panel constituting the partition wall structure. SOLUTION: Face members 2 are stuck to both faces of a frame body 3 to form a sound insulating partition panel 1. Face members 2 (2a, 2b) formed of gypsum boards different in thickness are stuck to one side face and the other side face. With this constitution, the face members 2 different in thickness are stuck to the respective side faces of the frame body 3, so that the coincidence frequency of each face member 2 is different, and lowering of transmission loss at the coincidence frequency can be effectively prevented. Coincidence of coincidence frequency of both face members can also be avoided by changing the rigidity and density of the face members at one side face and the other side face.
