2. Description of the Related Art Conventionally, as a soundproof building material, for example, a sound absorbing material made of glass wool, a foamed resin material, a rubber mat, or the like is directly laminated below a surface material, or one or more layers of a surface auxiliary material are interposed. In addition, those having a laminated plate structure that is indirectly laminated are known.

[0003] This conventional soundproof building material is usually formed in a rectangular or square planar shape, and a liquid or sheet-like adhesive is applied or applied to a construction base surface such as a floor or a wall slab. After the installation, the construction is performed by a method of applying a liquid adhesive to the side surface portion and sequentially tightening the adhesive from a reference position. Alternatively, a construction method is used in which a nail or a wood screw or the like is used instead of an adhesive material to sequentially tighten the foundation surface for construction.

[0004] In such a conventional soundproof building material, not only the sound insulating and sound absorbing functions inherent to the sound absorbing material are low, but also the sound absorbing material is directly or indirectly adhered to the construction foundation surface, so that the sound insulating performance cannot be obtained. There is a problem that. In addition, since it is constructed by a method of interposing an adhesive between the construction foundation surface and the adjacent soundproof building material, if the interposition of the adhesive is rough, the construction finish will be poor or an appropriate Since the mounting strength cannot be obtained, the work of interposing the adhesive must be performed very carefully, and there is a problem that the workability of the construction is low.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the soundproof building material according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a first embodiment of a soundproof building material according to the present invention.

In this embodiment, as shown in FIG. 1, a four-layer laminated plate structure is shown, and as shown in FIG. 2, a planar shape is shown as a rectangle.

The surface material 1, which is the uppermost layer in this embodiment, is made of relatively hard decorative wood such as veneer or plywood, the surface of which is coated. The surface material 1 has a long side shorter than a lower layer portion thereof, and is provided with a step-shaped joint groove 2 in all parts outside the short side of the surface material 1. A short rectangular joint plate 3 common to the joint groove 2 of the adjacent soundproof building material is fitted and bonded to the joint groove 2. The joint plate 3 is preferably made of the same material as the surface material 1 in consideration of appearance and the like.

A surface auxiliary material 4 is laminated and adhered to a lower layer of the surface material 1. This surface auxiliary material 4 is made of a relatively soft plywood or the like containing a cork material or the like.

A sound absorbing material 5 is laminated and adhered to a lower layer of the surface auxiliary material 4. The sound absorbing material 5 is obtained by directly applying electric current to a small metal piece such as cast iron, and heating and pressing the small metal piece to sinter it into a porous plate shape. When such a sinter is cooled, heat escapes to the center of the plate, so that the sintering density becomes low at the front and back surfaces of the plate and becomes dense at the center of the plate. For this reason, in this sound absorbing material 5, sound absorption becomes good at the front and back surfaces where the sintering density is low, and the sound absorbed at the center where the sintering density is high can be compressed and converted to extremely minute heat. . The sound absorbing and sound insulating functions of the sound absorbing material 5 are particularly excellent in a low frequency range, and have a characteristic that is stable from a low frequency range to a high frequency range. In addition, this sound absorbing material 5
It has a vibration damping function and the like. It is to be noted that the sound absorbing material 5 can be formed in a large number of layers with the above-mentioned sparseness and denseness, or can be made of a ceramic material.

Glass wool 6 is laminated and adhered to the lower layer of the sound absorbing material 5. The glass wool 6 functions as an auxiliary material for the sound absorbing material 5.

According to this embodiment, in order to perform the construction, the flat construction base surface 7 such as a floor surface or a wall surface is successively stretched without using an adhesive, and the entire construction base surface 7 or After a part of the joining, the adhesive material is applied to the back and side surfaces of the joining plate 3 and fitted into the joining groove 2 to bond the sound-tight building material adjacently attached and integrated. That is, the construction wool 7 is bonded to the glass wool 6 or the sound absorbing material 5 by an adhesive or other means.
Because it is not adhered to the sound, the sound absorbing performance is secured.
In addition, the use of the adhesive is extremely partial, and no special work is required for the use of the adhesive. For this reason, workability of construction is improved. In addition, it is also possible to paste a cushioning tile or a sheet-like decorative material on the surface material 1.

In the state constructed in this manner, even if stresses such as expansion, contraction, and bending act on the joint 8 of the soundproof building material due to humidity and the like, the joint plate 3 is positioned as a resistance to these stresses. As a result, the overall tensioning strength is increased, and the occurrence of knitting after construction is prevented. Further, since the sound absorbing material 5 exhibits much better sound absorbing and sound insulating functions than conventional materials due to the characteristics of the material, the soundproofing performance is enhanced. In particular, a sound absorbing material 5 having excellent sound absorbing and sound insulating functions in a low frequency range.
Since the glass wool 6 having excellent sound absorbing and sound insulating functions in a high frequency range is laminated under the lower layer, the soundproofing performance is extremely enhanced in the entire range from the low frequency range to the high frequency range due to the synergistic action of the two.

Since the sound absorbing material 5 has a vibration damping function, it is effective to prevent the transmission of vibrations downstairs when installed on a floor of a living room or the like. Also, the floor of the computer room,
When installed on a wall, it is effective in preventing the generation of computer noise.

FIG. 3 shows a second embodiment of the soundproof building material according to the present invention.

In this embodiment, the plane shape is shown as a square, and the joint groove 2 is formed in one part around four.

According to such an embodiment, there is an advantage that even if the joint groove 2 and the joint plate 3 are made small, a considerable tightening strength can be obtained.

FIG. 4 shows a third embodiment of the soundproof building material according to the present invention.

In this embodiment, the plane shape is a square, and the connecting groove 2 is formed in a square.

According to this embodiment, the four connecting grooves 2
Since the joint plate 3 is used in common, there is an advantage that the tensioning strength is increased.

FIG. 5 shows a soundproof building material according to a fourth embodiment of the present invention.

In this embodiment, the side surfaces of the joint groove 2 and the joint plate 3 are formed in a tapered shape.

According to such an embodiment, since the fitting of the connecting plate 3 to the connecting groove 2 can be performed smoothly, there is an advantage that the workability of construction is further improved.

FIG. 6 shows a fifth embodiment of the soundproof building material according to the present invention.

In this embodiment, the side surfaces of the joint groove 2 and the joint plate 3 are formed in a plurality of steps.

According to this embodiment, since the bonding area between the joint groove 2 and the joint plate 3 is increased, there is an advantage that the tensioning strength is increased.

FIG. 7 shows a sixth embodiment of the soundproof building material according to the present invention.

In this embodiment, a vibration absorbing synthetic resin material 9 is laminated on the front and back surfaces of the sound absorbing material 5 and further covered with a moisture proof synthetic resin material 10.

According to this embodiment, since the rust of the metal sound absorbing material 5 is prevented by the moisture-proof synthetic resin material 10, the durability is improved, and the construction can be performed around water or outdoors. There are advantages. Further, since the vibration absorbing function of the sound absorbing material 5 is assisted by the vibration absorbing synthetic resin material 9, there is an advantage that the vibration absorbing synthetic resin material 9 can be applied to a floor surface of a factory where vibration is severely generated.

As described above, in addition to the illustrated embodiment, it is possible to adopt an embodiment in which another member is additionally laminated on the upper layer side and the lower layer side of the sound absorbing material 5, or the above-mentioned lamination is removed.

[0037]

As described above, in the soundproof building material according to the present invention, the soundproofing performance is essentially secured because the sound absorbing material is not bonded to the construction foundation surface. In addition, since the sound absorbing material has good sound absorbing and sound insulating functions due to the characteristics of the sound absorbing material, there is an effect that soundproofing performance is enhanced.

Further, since the use of the adhesive at the time of construction is partial, there is an effect that the workability of construction is enhanced.

Furthermore, since the sound-tight building materials that are closely stretched are connected and integrated by a common joint plate, there is an effect of increasing the strength of stretching.

Further, since the vibration damping function is good due to the characteristics of the sound absorbing material, the use of the sound absorbing material is expanded to applications where vibration damping is required.

Further, in the soundproof building material according to the present invention, since the rust of the sound absorbing material is prevented,
This has the effect of improving durability and expanding its use in construction around water and outdoors.
