CEILING SOUND INSULATING STRUCTURE AND CEILING SOUND ISOLATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ceiling sound insulation structure for perfectly insulating heavy floor impact sound by a simple and inexpensive means while reusing industrial wastes from the viewpoint of cost and environment protection.

SOLUTION: This ceiling sound insulation structure 1 is so constructed that heavy floor impact sound generated in a second floor structure on the upstairs in a dwelling house is reduced at downstairs below a ceiling member 20 disposed on the lower part of the second floor structure. The ceiling member 20 is constructed by laying a plurality of ceiling cradlings 31 on a ceiling bed material 21. A designated amount of ceiling vibration control plates 22 are stuck between the ceiling cradlings 31 on the ceiling bed material 21. The weight of the ceiling vibration control plate 22 is set with a range of weight on the basis of the ceiling bed material 21, and the ceiling vibration control plate is shaped to be stored in a designated void between the ceiling cradlings 31.
