Abstract

PURPOSE:To prevent the propagation of sound in each adjacent room by adding a damping material to a continuous formation material which is used as a component for a floor, a wall., and for a ceiling, which is continuously extended to both adjacent rooms. CONSTITUTION:Each of adjacent room 10A, 10B is partitioned by a partition 11, and a floor component 12, a wall component 13, and a ceiling component 14 that form rooms 10A, 10B, which are adjacent with each other, are of a continuous component 15 continuously extended to both rooms 10A, 10B adjacent with each other. A damping material 16 made of a lead sheet of approximately 0.5mm in thickness and of approximately 70mm in width, is added to the continuous component 15, and the vibration propagated on the continuous component 15 is damped. The side pass propagation of sound in each adjacent room can thus be prevented.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a structure for preventing side channel propagation between adjacent rooms.

[Prior Art] When considering the sound insulation performance between adjacent rooms separated by a partition in a building, there are cases where sufficient sound insulation performance cannot be obtained even though the partition itself has a high sound insulation performance. In particular, at least one of a floor component, a wall component, or a ceiling component
If the continuous component extends continuously to both adjacent rooms, the continuous component becomes a vibration propagation path, which tends to cause sound to propagate between the adjacent rooms. This phenomenon is commonly referred to as side path propagation. FIG. 6 shows an example in which the ceiling component 1 is a continuous component and causes sound propagation P.

Note that 2 is a partition and 3 is a joist.

Conventionally, in order to prevent the above-mentioned side path propagation, floor construction materials,
It was necessary to separate the wall or ceiling components at the location of the partition without making them continuous, and to create an insulating structure between these components between adjacent rooms. FIG. 7 shows an example in which the ceiling component 1 is divided.

[Problems to be Solved by the Invention] However, in the conventional technique of creating an insulating structure for floor components, wall components, or ceiling components between adjacent rooms, division and allocation of each component becomes complicated. In particular, this is not appropriate for mass-produced houses because it increases the number of parts and the number of construction steps.

It is an object of the present invention to prevent side-path propagation of sound between adjacent rooms without increasing the number of building parts or the number of construction steps.

[Means for Solving the Problems] The present invention provides a method in which at least one of the floor component, wall component, or ceiling component constituting each of the adjacent rooms separated by a partition is continuous with both of the adjacent rooms. In this structure, a vibration damping material is added to at least a part of the continuous component in the structure for preventing side channel propagation between adjacent rooms, which is a continuous component extending from one chamber to another.

[Function] According to the present invention, when a floor component, a wall component, or a ceiling component is continuously extended to both adjacent rooms, vibrations that try to propagate along the continuous component are The vibration is immediately damped and damped by the damping material added to the continuous component. This makes it possible to prevent the propagation of sound between adjacent rooms while providing the floor, wall, or ceiling materials as continuous components without having to divide them at the partitions. Therefore, side-path propagation of sound between adjacent rooms can be prevented without increasing the number of building parts or increasing the number of construction steps due to separation of floor, wall, or ceiling components.

[Example] Fig. 1 is a schematic diagram showing an example of the present invention, Fig. 2 is an end view showing an example using a sheet-like damping material, and Fig. 3 is an example using a plate-like damping material. FIG. 4 is an end view showing an example using rod-shaped damping material, FIG. 5 is a line diagram showing the inter-room sound insulation performance according to the present invention, and FIG. 6 is a schematic diagram showing a conventional ceiling structure. , FIG. 7 is a schematic diagram showing a conventional ceiling insulation structure.

In Fig. 1, 11 is a partition, 12 is a floor component,
13 is a wall component, and 14 is a ceiling component. In this example, the partition 11 is made of 12 mm thick gypsum board (multilayer), the floor component 12 is made of 20 mm thick particle board, and the wall component 13 is made of 12 mm thick gypsum board. The ceiling component 14 is made of gypsum board with a thickness of 12 mm.

As shown in FIG. 2, the partition 11 has an adjacent room 10
A, IOB are partitioned, each adjacent room 10A, IO
The floor component 12, wall component 13, and ceiling component 14 that make up B are continuous components 15 that extend continuously to both of the adjacent rooms 10A and IOB, respectively.

However, in each of the floor component 12, the wall component 13, and the ceiling component 14 as the continuous component 15, there is a portion near the partition 11 in one adjacent room 10A! damping material 16 as shown in FIGS. 1 and 2, respectively.
or has been added. In this example, the damping material 16 is 0
．． 5mm thickness? It is constructed from a lead sheet with a width of hm.

Next, the operation of the above embodiment will be explained.

According to the above embodiment, when the floor component 12, the wall component 13, or the ceiling component 14 extends continuously to both the adjacent rooms 10A and 10B, the continuous component 15 (12, 13
, 14) is immediately attenuated and damped by the damping material 16 added to the continuous component 15. As a result, the floor component 12, wall component 13, and ceiling component 14 are arranged as a continuous component 15 without being separated at the position of the partition 11, and sound propagation between the adjacent rooms 10A and 108 is achieved. can be prevented.

Therefore, the side path propagation of sound between the adjacent rooms 10A and 108 can be prevented without increasing the number of parts of the building or increasing the number of construction steps due to separation of the floor components 12, wall components 13, and ceiling components 14. It can be prevented.

Figure 5 compares the sound insulation performance between rooms when the side channel propagation prevention structure shown in Figures 1 and 2 is adopted using damping material, and when the vibration damping material is not used. These are the experimental results. According to the present invention, it is recognized that the inter-room sound insulation performance (the level of reduction in sound volume transmitted between adjacent rooms) can be significantly improved.

In addition, as the damping material used in the present invention, metal materials such as steel and lead, stones, polymer materials, asphalt materials, rubber materials, etc. can be widely used, and the forms of use of the materials include sheets, plates, A wide range of rods etc. can be used.

FIG. 3 shows an example of the rod-shaped damping material 21, and the design includes a surrounding edge,
It can also serve as a beam etc. This damping material 21 is a composite body of a rubber plate 21A and a metal plate 21B.

FIG. 4 shows an example of a rod-shaped vibration damping material 22, which can also serve as a decorative border.

Further, in implementing the present invention, the damping material can be used as follows.

■The damping material can be placed in one or both of the adjacent rooms.

■Vibration damping materials can be used for part or all of each room.

The wider the range of use, the greater the vibration damping effect. If the range of use is limited to a part of each room, it is effective to use it near the partition.

0 Damping material can be installed using adhesives, metal fittings, or a combination of these.

[Effects of the Invention] As described above, according to the present invention, side-path propagation of sound between adjacent rooms can be prevented without increasing the number of building parts or the number of construction steps.
