Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention Industrial Field of Application The present invention relates to a building material that is easy to construct and has excellent sound and vibration insulation properties, and to a sound and vibration insulation room.

Conventional Technology Due to the need to prevent noise pollution and improve acoustic effects, there is a growing need to make architectural spaces B-proof and vibration-proof.

In reinforced concrete buildings, increasing the thickness of floors, walls, etc. increases the soundproofing effect, but this causes problems such as increased construction costs and decreased effective space.

There is a method of installing a soundproofing sheet made of inorganic fibers such as glass fiber under the floor or between walls, but the soundproofing effect is not sufficient.This is because the edges of floorboards and wallboards come into direct contact with joists and columns This is probably because sound propagates through the exposed parts.

As a vibration-proofing measure for equipment that generates noise and vibration, a plate-shaped body is integrally molded so that a combination of cylindrical protrusions with different diameters and heights are continuously and repeatedly arranged on at least one side of the body. Anti-vibration blocks made of an elastic material with a 100% elastic material have been molded, but since it is labor intensive and uneconomical to construct them all over a large building space, they have not been applied to general housing.

Problems that Soundproofing 1 aims to solve: There are various types and sizes of noise and vibration, and the required soundproofing and vibration proofing rates. Φ Anti-vibration design requires specialized knowledge and experience, and the effectiveness can be drastically reduced by carelessness or cutting corners during construction.

The present invention has soundproofing and vibration-proofing performance sufficient for constructing architectural spaces such as studios, which have extremely strict performance requirements regarding soundproofing and vibrationproofing, and can also be easily installed in general residences by constructors without special knowledge or experience. The purpose of the present invention is to provide a soundproofing/vibration proofing building material that is simple and easy to install, and a soundproofing/vibration proofing room using the same.

Means for Solving the Constituent Problems of the Invention The first invention relates to a building material for soundproofing and vibrationproofing. A soundproof and anti-vibration blower, made of an elastic material, is formed on one side of a wooden board and has a shape in which a combination of cylindrical protrusions with different diameters and heights are arranged in a continuous manner. fixed at intervals,
Moreover, it has a structure in which sheet-like inorganic fibers are adhered to the entire surface except for the portion where the block is fixed.

This will be explained in detail with reference to the accompanying drawings. Figure 3 shows the soundproofing/vibration proofing block 1, which is an important component in this invention.
Fig. 4 is a plan view of the same, and Fig. 4 is a side view of the same as seen from the right side.On both sides of the plate-shaped main body 11 made of an elastic material, the warp is 1).
Something approaching! Cylindrical protrusions 12A, 12B, 12 having different diameters and heights are low in height for those with large Shiten Roku and Retsubi tails.
Combination G, 120 (temporarily shown surrounded by a dotted line in Figure 3)
It has a shape that is integrally molded so that it is arranged in a continuous manner.

These types of cylindrical protrusions with different diameters and heights start with 12A, which has the largest diameter, and decrease in diameter in the order of 12B, 12G, and 120. Conversely, 12A has the lowest height, and 12A has the smallest diameter.
The height increases in the order of B, 12C, and 120. Although the figure shows a case in which these four types are combined, there may be more types, for example, a combination of six types.

The diameter of these cylindrical projections is a minimum of 3 mm to a maximum of 10 mm.
It is preferable that the height is changed within a range of 1 mm at the minimum and 5 mm at the maximum.

When providing a combination of cylindrical protrusions on both sides of a plate-like body, as can be understood from FIG. There is a cylindrical protrusion with the smallest diameter on the - side, and a cylindrical protrusion with the largest diameter is on the opposite side corresponding to the position where the cylindrical protrusion with the smallest diameter exists on the - side. It is better to arrange them in reverse order so that they exist.

The number of combinations of cylindrical protrusions with different diameters and heights (tentatively shown surrounded by dotted lines in Figure 3) that are continuously and repeatedly arranged in one block is about 4 to 12. It is appropriate to do so. FIG. 3 shows the case of six sets.

The type of elastic material constituting the soundproofing/vibrationproofing block is one based on natural rubber or synthetic rubber.

The appropriate thickness of the plate-like main body 11 is about 10 to 15 mm.

As shown in FIG. 1 as a plan view and as shown in FIG. 2 as a side view, the soundproofing and vibrationproofing building material according to the present invention has the above-mentioned soundproofing and vibrationproofing block 1 on one side of the wooden board 2 (the top side in the figure). It has a structure in which the blocks are fixed at intervals, and a sheet-like blank 8m113 is attached to the entire surface except for the part where the blocks are fixed.

As the wooden board 2, it is usually convenient to use plywood, especially a regular-sized wooden board.

The soundproofing/vibration proofing blocks fixed on the wooden board are required at least at the four corners of the wood board, and the mutual spacing is usually about 90 cm to 30 cm (core to core). When using it as a flooring material and installing mB objects on it, this interval may be shortened according to its gL(f load).

Sheet-like atam3 includes glass wool sheet,
Slag wool sheets and the like, which are generally commercially available as soundproofing or heat insulating materials, can be used.

In order to attach the sheet-shaped inorganic fiber 3 to the entire surface except for the part where the soundproofing/vibration proofing block l is fixed, cut out the part corresponding to the installation position of the soundproofing/vibration proofing block in advance, and then cut it out. It is sufficient to cover and adhere the soundproof fist vibration-proof blocks fixed to one side of the wooden board 2 at intervals.

Further, for the purpose of further imparting an electromagnetic wave shielding effect to the soundproofing/vibration-proofing building material of the present invention, a covering layer made of sheet-like aluminum may be provided on the structure shown in FIGS. 1 and 2. As the aluminum, aluminum foil, aluminum vapor-deposited plastic film, or the like can be used. Some glass wool sheets commercially available as heat insulating materials have a cover made of an aluminum-deposited plastic film, so if you use that, you will automatically have a covering layer made of sheet aluminum.

The construction method for the soundproofing and vibrationproofing building material according to the present invention is such that the wooden board surface to which the anti-RF/vibration block is not fixed is on the indoor side.For example, when using it as a flooring material, the second
Construct with IE upside down from the state shown in the figure.

It is sufficient to allow only the noise, but if the noise or vibration is severe,
Or, if a high degree of soundproofing or vibration proofing is required,
This soundproofing/vibration-proofing building material can be installed in two or three layers.

By applying this anti-vibration building material only on the floor and using general sound-insulating materials such as inorganic sheets such as Glass Cool on the walls and ceiling, considerable sound and vibration-proofing effects can be achieved. However, if you want to further increase the soundproofing and vibrationproofing efficiency, you can construct the floors and walls with this soundproofing and vibrationproofing building material, and connect the ceiling panels to the beams using the Hokki soundproofing and vibrationproofing blocks. By suspending the structure from timber and assembling it, it is possible to almost completely shield sound and vibration.

That is, the second invention provides a continuous combination of cylindrical protrusions having different diameters and heights on at least one surface of the plate-like main body, in which cylindrical protrusions having different diameters and heights have a high height when the diameter is small, and a height when the diameter is thick is low. Soundproofing and vibrationproofing blocks made of an elastic material and having a shape that is integrally formed so as to be repeatedly arranged are fixed at intervals on one side of a wooden board, and a sheet-like non-Japanese fiber is placed on that side. The floors and walls are made of anti-friction and anti-vibration building materials that are adhered to the entire surface except for the parts where the above blocks are fixed, and the ceiling panels are attached to beams through soundproof Φ anti-vibration blocks. This is a soundproof and vibration-proof room with a structure that is suspended from timber and assembled.

To explain this with reference to FIG.
After constructing the vibration-proofing building material, the ceiling board 9 is attached to the beam material 7 via the soundproofing/vibration-proofing block l (suspended from the hanging metal fittings lO).
hang from.

An example of the structure of this hanging part is explained in detail in FIG. 8, in which the soundproofing/vibration proofing block l is installed at the bottom of a hollow box 8 with a hole 81 in the bottom. A hook 82 is attached downward to the center of the block 1, and a hanging fitting 10 from which a ceiling plate 9 is suspended is attached to the lower end of the hook 82.

On the other hand, the box 8 itself is suspended from the beam 7 by an upper hook 83. In this way, the ceiling board can be suspended from the beam material via the soundproof/vibration proof blower 2.

An appropriate sound absorbing panel may be used as the ceiling board.

Such a soundproof/vibration proof room can be used to completely shield external Wq9 and vibrations and keep the room quiet, even if there is a strong sound source inside the room and you want to prevent it from leaking outside. Also great if you want.

Single-dish vibrations are mainly propagated by contact between solid objects, and sound is propagated through air and solid objects.

When a floor, wall, or ceiling is constructed using the soundproofing/vibration proofing building material of the present invention, the wooden board comes into solid contact with the outside structural material through the soundproofing/vibration proofing blocks fixed at intervals on one side. That means you are doing it.

This soundproofing and vibrationproofing block has a combination of cylindrical protrusions with different diameters and heights arranged on both sides, with those having a small diameter having a high height and those having a large diameter having a low height.

Therefore, microscopically, the wooden board is in solid contact with the outer structural material only through the cylindrical projections of the sound- and vibration-proofing block.

When the soundproofing and vibrationproofing building material of the present invention is used in a state where no load is applied, for example, as a wall material, the propagation path of sound and vibration through the solid contact part is "Tallest cylindrical protrusion on one side - Plate-like body - Opposite side. This is the highest cylindrical protrusion, and the part that comes into contact with a solid is very small, so the sound and vibration energy propagated by contact with a solid is small, and both the cylindrical protrusion and the plate-like body are made of elastic materials. Even small amounts of sound and vibration energy propagated from the part that makes contact with a solid object are absorbed between them and attenuated by the time they reach the opposite side.

In particular, the sound-proofing/vibration-proofing block is arranged so that, on one side of the plate-like body, there is a cylindrical protrusion with the largest diameter and a cylindrical protrusion with the smallest diameter on the opposite side. If the cylindrical protrusions on one side are arranged in reverse order, such that the cylindrical protrusion with the smallest diameter exists on the opposite surface, the cylindrical protrusion with the largest diameter exists on the opposite surface. Cylindrical projection - plate-shaped body -
M2, t (1m small? Hemorrhoids are also 1α wide circle with 11 spaces left) Since the hemorrhoids will be as long as the hemorrhoids, the sound and vibration damping effect will be further enhanced.

Furthermore, since sheet-like inorganic fibers are present in the portions where the vibration isolating block is not fixed, sound is prevented from propagating through the air.

When there is a sound source such as a piano in the room, the sound energy propagated to the outside through the floor is large. When something is placed on it, the highest cylindrical protrusion receives the load and is compressed in order, and the lower cylindrical protrusion receives no or only a small amount of load.

The plate-shaped body made of elastic material deforms under uneven pressure, creating a complex compressive stress distribution inside the plate-shaped body, which effectively absorbs waves and vibrations of different wavelengths and directions. do.

It is free to apply any interior decoration material to the floor and wall surfaces of a room where the soundproofing/vibrationproofing building material of the present invention has been applied.

Note that as a method for ventilating a room in which the soundproofing/vibration proofing building material of the present invention has been constructed, a ventilation fan with a silencer may be installed to take in air.

! l, so that where there is a cylindrical protrusion with the largest diameter on one side, there is a cylindrical protrusion with the smallest diameter on the opposite side, and a circle with the smallest diameter on one side. The soundproofing/vibration-proofing blocks are arranged in the reverse order so that the columnar projections having the maximum diameter are present at the positions on the opposite side corresponding to the positions where the columnar projections are present, and the thickness is 22 mm.
As shown in Figure 1, approximately 90cm
Six blocks were fixed at m intervals, and a glass fiber sheet with a thickness of 22 mm was attached to the entire surface, except for the area where the soundproofing and vibrationproofing blocks were fixed, to create a soundproofing and vibrationproofing building material.

Example of Use One or two sheets of the soundproofing/vibration-proofing building material of Example 1 are applied to the floor, and an upright piano (heavy weight 200kg+
A chair and a player with a weight of 7 kg) were installed, and the absorption rate of sounds of 20 Hz and 80 Hz (do-do) generated by the piano was measured under the floor.

The results are shown in Table 51.

Table 1 (Vibration Absorption Rate) As shown in Table 1, more than 99% of the 80Hz sound is absorbed by just installing one piece of the soundproofing and vibrationproofing building material of the present invention, and the sound is transmitted to the outside. is less than 1%. 20H
As for the bass sound of z, more than 90% of it can be absorbed by installing two pieces of the soundproofing/vibration proofing building material of the present invention.
