PROBLEM TO BE SOLVED: To enable adjustment of vibration damping effect while keeping the amount of viscoelastic bodies small, at the same time securing the vibration damping effect by preventing separation between a ceiling plate and the viscoelastic body in a ceiling structure.SOLUTION: A ceiling structure supports a ceiling plate 3 by having an edge part thereof mounted on support plates 12 fixed on a wall 2. The ceiling structure includes viscoelastic bodies 14 provided between a top surface of the support plates 12 and an edge part undersurface of the ceiling plate 3, in a divided section, and guide plates 13 fixed on the wall 2 above the support plates 12 for guiding an edge part top surface of the ceiling plate 3. Furthermore the viscoelastic bodies 14 between an undersurface of the guide plates 13 and the edge part top surface of the ceiling plate 3 are provided in a divided section. Specifically, a parting material 11 integrated with the support plate 12 and the guide plate 13 is provided.SELECTED DRAWING: Figure 1 |
