上での難点があった。2. Description of the Related Art A sound absorbing plate is generally known as a glass wool material. For example, for construction, a combination of a surface decorative plate 1 having a perforated portion 2 on the surface, a glass wool material 3, and a sound insulating plate 4 is used as shown in FIG. Therefore, if the perforated portion 2 of the surface decorative plate 1 is enlarged, the glass wool material 3 of the sound absorbing plate becomes visible from the outside. Therefore, a large number of thin holes are generally provided in order to make it blind. The perforated portion 2 of the surface decorative plate 1 has a design that is inconspicuous, and is also used by devising such as using a cloth as a base. However, such a conventional sound absorbing material has a low degree of freedom in designing the surface decorative plate 1 and is uniform, and is highly practical as a sound absorbing effect, but has a design difficulty.

ける自由度は今一歩の改善が望まれていた。On the other hand, it is known that the metal porous sound absorbing plate is manufactured by various methods using aluminum as a raw material. Among them, the one manufactured by the sintering method is composed of a porous body in which porous parts are connected, The sound absorbing effect has the same performance as that of glass wool, and its natural color obtained by sintering metal powder also has the function as a surface decorative plate, but there is a demand for further improvement in design freedom. It was

建築用吸音板として問題があった。Therefore, as a method of increasing the degree of freedom in designing the surface decorative plate, a porous metal material may be buried in an opening hole portion (hereinafter referred to as a hole portion) of the plate-shaped material, and these may be integrated. This technical idea is disclosed in Japanese Utility Model Publication No. 63-31117. However, the technical idea is to disperse the aluminum powder raw material in the holes and integrate it by means such as metallurgical means. The biggest drawback is that the raw material powder 5 is dispersed in the holes. Therefore, when spraying, excess powder is removed by a cutter 6 etc. as shown in FIG. 12, but it is difficult to remove completely and cannot be used as a surface material.
In addition, the idea that the opposite surface is the surface also causes the raw material powder 5 to wrap around other than the holes (in the direction of the arrow) due to vibration or movement of the base plate 8 where the plate-shaped material is slight (only in the direction of the arrow). It is difficult to integrate it with a plate-shaped material, and there has been a problem as a sound absorbing board for construction in which cosmetic properties are also important.

As shown in FIG. 2, a fixed clearance is provided in the hole of the plate member 11 and the plate member 11 is inserted in a free state.

得られた。The metal porous sound-absorbing material 13 preferably has a porosity of 40 to 50% in order to expect a highly practical sound-absorbing coefficient, and its pores are almost in communication with each other. Therefore, it was thought that the growth against reduction could not be expected.
Moreover, since it is not possible to increase the rolling reduction to expect a porosity of 40 to 50%, the rolling reduction is good so that it does not affect the sound absorption coefficient. Desirably, punching is performed at a reduction ratio of 3 to 5% to reduce the noise absorption. It is necessary to press and press the material 10 and fix it to the plate-shaped material 11. Therefore, in the state of FIG. 2 in which the four sides are restrained, the air in the holes of the punched sound-absorbing material 10 expands at the time of compression, so that the expansion and expansion action more than the expansion due to the reduction in the free state ( When the elongation due to the arrow) was predicted and verified by experiments, a practically adhered state was obtained.

い事を確認した。The experiment first measured elongation in the free state. The maximum measurement result was 2.4 mm with respect to 500 mm. Conditions: Aluminum porous sintered material Width 500 x 500 m
m, thickness 3.0 mm, porosity of 46% was passed between the rolls, rolling was repeated several times to reduce the thickness by 5%, and elongation was determined to be 2.4 mm at maximum in the rolling direction. Elongation was obtained. This value is about 1/1 of cast aluminum plate
Corresponding to 0, it was confirmed that the compressive deformation portion was absorbed in the void portion and the elongation was small.

考えられる。Next, a disk having a diameter of 14.0 mm was punched out from the aluminum porous sintered material, and the diameter was 15.0 m.
Clearance of 0.5m on an aluminum plate with m cut out
It was inserted in a free state with a space of m, pressed down under the condition that the thickness was reduced by 5%, and fixed to a plate-shaped aluminum plate. Furthermore, when the pulling force was measured, 3
It was confirmed that there is a sticking force to be released by a compressive force of 0 to 50 kg, and that the air inside the porous body expands and expands when it is pressed. Furthermore, considering its action, when the above-mentioned sintered material is cut out, the fact that many pores on the side surface are closed by pores due to shearing force also prevents air leakage and contributes to expansion of elongation. It is thought that they are working.

Is integrally fixed to the opening hole portion of the plate-shaped material, and the surface of the plate-shaped material is formed in a planar shape and / or a projection shape. The porous metal sound absorbing material having the same shape as the opening hole portion is inserted into the opening hole portion in the free state, and then pressed and fixed by pressing.

が期待出来る。Since a metal porous sound absorbing material having the same shape as the hole is pressed and fixed to a plate-shaped material having a hole to form a sound-absorbing material, various decorative wood boards and plasters can be used in addition to selecting a metal for the plate-shaped material. In combination with a board, etc., the porous metal sound absorbing material can be designed to include a three-dimensional shape such as a circle or a corner, so that a design that cannot be seen in the past can be expected.

The peak of the sound absorption coefficient is the same, and a value of the same level is obtained for 1000 Hz which is a general noise frequency component, and the practicability as a sound absorbing material is sufficiently retained. Further, the application range can be expanded by using the plate-shaped material as a vibration damping material.
