  In the said embodiment, in each anti-vibration ceiling panel 8A-8D, the several dynamic damper 12 is arrange | positioned at equal intervals (pitch P3, P4) to the vertical direction and the horizontal direction. Thereby, the anti-vibration effect can be exhibited evenly within the range in which the dynamic dampers 12 of the anti-vibration ceiling panels 8A to 8D are provided.

  In the said embodiment, while the edge part of each field edge 10a-10d is connected by the field edge receiver 11a for 1st edge parts, and the field edge receiver 11b for 2nd edge parts, the edge of each field edge receivers 11a-11d The parts are connected by the first end field edge 10a and the second end field edge 10b. Thereby, compared with the case where the edge part of each field edge 10a-10d and each field edge receiver 11a-11d is a free end, the deformation | transformation of the edge part of each field edge 10a-10d and each field edge receiver 11a-11d And damage can be suppressed. Therefore, the strength of the anti-vibration ceiling panels 8A to 8D can be improved.

  In the embodiment, dynamics are provided at the intersections between the second end field edge 10b and the field edge receivers 11a to 11d and at the intersections between the second end field edge receiver 11b and the field edges 10a to 10d. It is not done. Therefore, when two anti-vibration ceiling panels (for example, anti-vibration ceiling panels 8A and 8B) are arranged in the vertical direction so that the first end field edge 10a and the second end field edge 10b are adjacent to each other. In addition, the dynamic damper 12 can be prevented from being concentrated at the boundary between the anti-vibration ceiling panels 8A and 8B. Similarly, the two anti-vibration ceiling panels (for example, anti-vibration ceiling panels 8A and 8C) are arranged in the horizontal direction so that the first end field receiver 11a and the second end field receiver 11b are adjacent to each other. When arranged, the dynamic dampers 12 can be prevented from being concentrated at the boundary between the anti-vibration ceiling panels 8A and 8C. Therefore, in the state in which the plurality of anti-vibration ceiling panels 8A to 8D are installed, the anti-vibration effect can be exhibited evenly on the ceiling surface constituted by the anti-vibration ceiling panels 8A to 8D.

  In the embodiment, in the state where the vibration-proof ceiling panels 8A to 8D are arranged in the vertical direction and the horizontal direction, the dynamic dampers 12 can be arranged in the vertical direction and the horizontal direction at substantially the same pitches P3 and P4. Therefore, the vibration-proof effect can be exhibited evenly on the top surface formed by the plurality of vibration-proof ceiling panels 8A to 8D.

  In addition, in the said embodiment, while connecting the edge parts of each field edge 10a-10d with the edge part edge receivers 11a and 11b, the edge part of each field edge receiver 11a-11d is edge part edge edge 10a. 10b. However, the said embodiment is not limited to connecting the edge parts of each field edge 10a-10d and each field edge receiver 11a-11d. When the edge field edge and the edge field receiver are omitted, the concentrated arrangement of the dynamic dampers 12 between the adjacent anti-vibration ceiling panels 8A to 8D can be avoided. Therefore, it becomes easy to arrange the dynamic dampers 12 at equal intervals in a state where the plurality of anti-vibration ceiling panels 8A to 8D are arranged.

  Further, only the second end field edge 10b and the second end field edge receiver 11b, which are unrelated to the arrangement of the dynamic damper 12, can be omitted. If it does in this way, weight reduction and cost reduction of the anti-vibration ceiling panels 8A-8D can be achieved by omitting the field edge 10b and the field edge receiver 11b.

  In the embodiment, the attachment portion 18 is removable with respect to the support member 7. Therefore, the anti-vibration ceiling panels 8A to 8D can be recycled by removing the anti-vibration ceiling panels 8A to 8D from the support member 7 when the building 1 is disassembled. When using a field edge and a field edge receiver having a length corresponding to the size of the ceiling as in the past, not only removing it from the floor component when dismantling the building, but also attaching it to the outside of the building It is also difficult to carry. On the other hand, as described above, the anti-vibration ceiling panels 8A to 8D can be configured in a compact manner, and it is possible to efficiently perform the removal work and the transport work during disassembly.

  In the said embodiment, the pitch P2 of the vertical direction and the pitch P1 of the horizontal direction of the connection position (each suspension member) of the floor structural member 2 and the ceiling structural member 3 can be made substantially the same. Thereby, the vibration mode produced in the ceiling surface comprised by the ceiling structural member 3 can be limited to a specific vibration mode. Therefore, since the tuning range of the resonance frequency of the dynamic damper 12 can be limited, the vibration isolation effect can be further improved.

  In the embodiment, the attached portions 7 c are provided on both lateral sides of the support member 7. Therefore, the anti-vibration ceiling panels 8A to 8D can be placed on the attached portions 7c of the support members 7 adjacent to each other, and the anti-vibration ceiling panels 8A to 8D can be attached to the support member 7 from below in this state. Therefore, compared with the case where the operator located under the support member 7 lifts the anti-vibration ceiling panels 8A to 8D and attaches the anti-vibration ceiling panels 8A to 8D to the support member, the burden on the operator is reduced. can do.

  In the said embodiment, each anti-vibration ceiling panel 8A-8D has the sound-absorbing material 17 clamped between the clamping panel 15 and the field edge receivers 11a-11d. Thereby, propagation of the impact sound from the upper floor to the lower floor can be suppressed more effectively. Here, the sandwiching panel 15 that sandwiches the sound absorbing material with the field edge receivers 11a to 11d is fixed to the field edges 10a to 10d so as to open the attachment portion 18 downward. Thereby, attachment to the to-be-attached part 7c of the attachment part 18 is accept | permitted obtaining the suppression effect of the impact sound mentioned above. And in the said embodiment, the coating | coated panel 16 fixed to the clamping panel 15 so that the attaching part 18 may be covered from the bottom is provided. Thereby, the attachment part of the anti-vibration ceiling panels 8A-8D and the support member 7 is coat | covered from the bottom, and the external appearance of a ceiling structural member can be made favorable.

  With the implementation value, each suspension member 6 can adjust the height position of each support member 7. Thereby, by adjusting the height positions of the anti-vibration ceiling panels 8A to 8D, the ceiling surface constituted by the anti-vibration ceiling panels 8A to 8D is adjusted to be flat and horizontal (non-landing). Adjustment).

  In addition, in the said embodiment, although the floor slab (for example, reinforced concrete slab) was illustrated as the floor structural member 2, the floor structural member 2 is not limited to this. The floor component 2 may include, for example, a flooring and a plurality of floor beams 5 (see FIG. 7) that support the flooring from below. In this case, the upper end portion of the suspension member 6 can be attached to the floor beam 5 as shown in FIG.

  Moreover, although the said embodiment demonstrated the ceiling structural member 3 which has the dynamic damper 12, the ceiling structural member 3 may have the anti-vibration material which attenuates a vibration by an own deformation | transformation. For example, as shown in FIG. 7, a vibration isolating material 19 made of an elastic material can be provided between the nut 6 b of the suspension member 6 and the floor beam 5. Thereby, it can suppress that the vibration which arose on the upper floor by the elastic deformation of the vibration isolator 19 propagates to a lower floor. In particular, the dynamic damper 12 suppresses the propagation of vibration in a specific band whose resonance frequency is tuned, and thus is effective in reducing the heavy floor impact sound, whereas the vibration isolator 19 is relatively wide. Since vibration is suppressed in the band, it is effective in reducing light floor impact sound. Here, the heavy floor impact sound is an impact sound caused by low-frequency vibration generated when a person on the upper floor runs around. Further, the lightweight floor impact sound is an impact sound caused by vibration at a medium to high frequency that occurs when an object falls or when an object is dragged.

  However, in the RC structure, it is possible to easily reduce the lightweight floor impact sound by increasing the weight of the flooring material. Therefore, the vibration isolator 19 can be omitted in the reinforced concrete structure.

  In addition, although the said embodiment demonstrated the anti-vibration ceiling panels 8A-8D which have the four field edges 10a-10d and the four field edge receivers 11a-11d, the number of a field edge and a field edge receiver is There is no limitation as long as it is a plurality. The number of dynamic dampers is not limited as long as it is plural.
