PROBLEM TO BE SOLVED: To provide a vibration control ceiling structure having earthquake resistance.SOLUTION: A vibration control ceiling structure 1 comprises: a hanging bolt 11 suspended from a super structure 2; a hanger 12 attached to the lower end of the hanging bolt 11 and formed in a frame shape in cross-sectional view; a vibration-proof material 13 in a quadrangular pyramid shape formed and accommodated in an inner space of the hanger 12; a penetration bolt 14 ranging from the lower end of the hanger 12 to a ceiling substrate; and a diagonal member 15 for restricting the hanger 12. Left and right side faces of the vibration-proof material 13 are in close contact with the inner face of the hanger 12, and the penetration bolt 14 penetrates through the bottom of the hager 12 and the vibration-proof material 13 and is locked to the top face of the vibration-proof material 13. |
