Abstract

PROBLEM TO BE SOLVED: To control the propagation of oscillation by fixing a supporting batten to the upper end of a partition wall, fixing ceiling joists to both sides of the supporting batten with buffers therebetween, and fixing ceiling boards holding the partition wall to the ceiling joists. SOLUTION: A frame is formed of wooden battens 21, panels 22 are fixed to both sides of the frame to form a partition wall 2, and a supporting batten 3 is fixed on the upper surface of the wooden battens 221 of the partition wall 2. Ceiling joists 4 are fixed to both sides of the supporting batten 3 with buffers 5 therebetween and, at the same time, the buffers 5 are also arranged on the upper surface of the supporting batten 3 to fix ceiling joist holders 1. Ceiling boards 6 are arranged to both sides across the partition wall 2, and the ceiling boards 6 are fixed respectively to the ceiling joists 4. Accordingly, even if one of the ceiling boards 6 is oscillated by impact, since it is damped by the buffers 5, no oscillation occurs in the other of the ceiling boards 6, and the effect of sound insulation can be promoted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building vibration damping structure.

[0002]

2. Description of the Related Art A ceiling plate is generally fixed directly to a structure such as joists or beams. However, in this case, since the vibration propagates through the ceiling plate through the structure, it is easy for sound to be transmitted to the adjacent room over the partition wall.

As a countermeasure against this, conventionally, the ceiling plate is hung from the structure by using a hanging metal fitting.
This hanging metal fitting is made by connecting a pair of metal fittings via anti-vibration rubber, and one metal fitting is fixed to the edge that fixes the ceiling plate, and the other metal fitting is fixed to the structure, Vibrations can be damped by a rubber band (for example, Japanese Patent Laid-Open No. 6-341191, JP-B 62-8).
265).

[0004]

However, in the conventional ceiling vibration damping structure as described above, a large number of hanging fittings and a fixture for fixing the hanging fittings to the field edge and the structure are required. Therefore, the number of parts is increased and the cost is high, and since it is necessary to fix a large number of hanging fittings to both the field edge and the structure, the construction is very complicated and troublesome. .

In view of the above, the present invention focuses on the above-mentioned problems, and at the same time, at a low cost, the construction is simple, and it is possible to make it difficult for sound to be transmitted between rooms separated by a partition wall. The purpose is to provide a swing structure.

[0006]

In order to achieve the above object, in the ceiling vibration damping structure according to the first aspect of the present invention, a receiving bar is fixed to the upper end of the partition wall, and buffers are provided on both sides of the receiving bar. In the ceiling vibration damping structure according to the present invention, the receiving bar is connected to the field by fixing the field edge through the cushioning material. The structure is fixed to the frame.

[0007]

In the ceiling damping structure according to the first aspect of the present invention, when the ceiling plate provided on one of the partition walls vibrates due to some impact, the vibration is transmitted to the ceiling plate provided on the other of the partition walls. By the time it is transmitted, it is damped by the cushioning material between the receiving bar fixed to the upper end of the partition wall and the field edges fixed to both sides thereof. That is, even if the ceiling plate arranged on one of the partition walls vibrates, the ceiling plate arranged on the other of the partition walls hardly vibrates.

In the ceiling damping structure according to claim 2 of the present invention,
The vibration of the ceiling plate provided on one of the partition walls is damped not only by the cushioning material between the receiving bar and the field edge, but also by the cushioning material between the receiving bar and the field edge. It is possible to more effectively suppress the propagation of vibration to the ceiling plate arranged on the other side of the partition wall.

BEST MODE FOR CARRYING OUT THE INVENTION First, the ceiling damping structure of the first embodiment will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a ceiling damping structure according to the first embodiment, and FIG. 2 is a sectional view showing the ceiling damping structure according to the first embodiment.

In the figure, reference numeral 1 denotes a field frame receiver, which is arranged in parallel at a predetermined interval and has both ends fixed to a ceiling beam (not shown).

In the figure, reference numeral 2 denotes a partition wall, which is erected in a direction orthogonal to the field edge receiver 1. This partition wall 22
Is a wooden frame 21 that forms a frame, and panels 2 are provided on both sides of the frame.
2 and 22 are fixed to each other, and the receiving bar 3 is fixed to the upper surface of the wooden bar 21 located at the upper end, and the receiving bar 3 is fixed to the field edge receiver 1.

In the figure, reference numeral 4 denotes a field edge, which is fixed to both sides of the receiving bar 3 via cushioning materials 5, and the field edge 1
It is also fixed to the underside of. In addition, as the cushioning material 5,
5 m of polyethylene foam or synthetic rubber foam
It is optimum to use the one having a thickness of about m.
Further, it is desirable that the cushioning material 5 is adhered to at least one of the receiving bar 3 and the field edge 4.

In the figure, reference numeral 6 denotes a ceiling plate, which is provided on both sides of the partition wall 2 with the partition wall 2 interposed therebetween, and each is fixed to the field edge 4.

Therefore, even if one of the ceiling plates 6 vibrates due to some impact, the vibration is
By the time it is transmitted to the other ceiling plate 6, the partition wall 2
Since it is damped by the cushioning material 5 between the receiving bar 3 which is fixed to the upper end portion and the field edge 4 which is fixed to both sides thereof, the other ceiling plate 6 hardly vibrates. .

That is, in this ceiling damping structure, the partition wall 2 is provided by providing the cushioning material 5 between the receiving bar 3 and the field edge 4.
Since the propagation of vibrations between the ceiling plates 6 and 6 arranged on both sides of the partition wall 2 is suppressed, the cost is low and the construction is simple, but the space between the rooms with the partition wall 2 is separated. It has an excellent structure that makes it difficult for sound to be transmitted. Compared with the case where the ceiling plate 6 is directly fixed to the joists and beams, the sound insulation effect is about 1 dB in the low-pitched sound area and about 2 dB in the high-pitched sound area.
Could be improved.

It is also provided between the wooden bars 3. Therefore, the vibration of the ceiling plate 6 provided on one of the partition walls 2 causes not only the cushioning material 5 between the receiving bar 3 and the field edge 4 but also the vibration between the receiving bar 3 and the field edge 1. It is also designed to be damped by the buffer material 5.

In the ceiling vibration damping structure of the fifth embodiment, as shown in FIG. 6, the partition wall 2 is erected in parallel with the field edge receiver 1, and the field edge 4 fixed on both sides of the receiving bar 3 is also provided.
