Description

[Detailed description of the invention] The present invention has a U-shaped or almost U-shaped cross section, and an L-shaped or almost L-shaped flange part for joining with an adjacent plate of the same structure is integrated into the opposing plate part. The present invention relates to a soundproof wall member comprising a main body made of a rigid material and a plate-shaped sound absorbing material fixed to the main body so as to close an opening of the main body with a compression molded product of inorganic fiber.

In conventional devices, as a means to achieve a soundproofing effect on the joining flange portion, a method is adopted in which a sound absorbing material different from the plate-shaped sound absorbing material that closes the opening of the main body is adhered to the surface of the flange portion. was, but
This method increases construction man-hours, deteriorates construction efficiency, and has the disadvantage that joints and steps between the two types of sound absorbing materials tend to break, resulting in a poor and brittle wall finish.

The present invention aims to eliminate such drawbacks.

The soundproof wall member according to the present invention is characterized in that a sound-absorbing material portion covering the surface of the flange portion of the main body is integrally molded into the plate-shaped sound-absorbing material.

In other words, since the sound-absorbing material covering the surface of the flange is integrally formed with the plate-like sound-absorbing material that closes the main body opening, it is possible to achieve soundproofing on the surface of the joining flange, while still achieving sound absorption. The number of man-hours required for constructing the material is just one step of fixing the plate-shaped sound absorbing material, and overall the workability can be improved compared to the conventional method mentioned above. Moreover, since there is no need to form a seam or step between the plate-shaped sound absorbing material that closes the main opening and the sound absorbing material portion that covers the flange surface, the wall surface finish is good. Since only one size is required, it is possible to reduce costs by improving the productivity of the sound absorbing material.

Particularly, when the plate-shaped sound-absorbing material is integrally formed with a portion that elastically fits into the internal space of the main body, the plate-shaped sound-absorbing material can be fixed to the main body easily and quickly.

Hereinafter, an embodiment of the present invention will be described based on the drawings. The soundproof wall is constructed by connecting a plurality of soundproof wall members 1 of unit width side by side in the width direction and fixing them to pillars at appropriate intervals. Wall member 1
This is a bent product made of a vinyl-coated steel plate (an example of a rigid material), and has a substantially U-shaped cross section, and the opposing plate portions 3A and 3A are adjacent to each other with the same structure. and bolts to connecting fitting A.
The main body 3 of the sound insulating case 3 has L-shaped flange parts 3a, 3a for co-tightening jointed together via a nut B, and a high-density (60 to 200 kg/ ^m3 ) is a compression molded product, and includes a plate-shaped sound absorbing material 4 fixed to the main body 3 so as to close the opening thereof, and a space surrounded by both of these 3 and 4 filled. The sound absorbing material 5 is made of low density inorganic fibers.
The sound-absorbing material portions 4a, 4a covering the surface are formed in a continuous and integral state, and the internal space of the main body 3,
That is, the protruding portions 4b, 4b that elastically fit into the opposing plate portions 3A, 3A are formed in a continuous, integral state. In addition, the plate-shaped sound absorbing material 4 has the protruding portion 4
Adhesion of b, 4b to the inner surface of the opposing plate portions 3A, 3A,
Flange portions 3a, 3 of the sound absorbing material portions 4a, 4a
By adhering to the surface a, the protruding portions 4b,
4b to the main body 3 by an elastic fit. Further, the filled sound absorbing material 5 is adhered to the main body 3.

3 to 6 show different embodiments, respectively.

In another embodiment shown in FIG. 3, the plate-shaped sound-absorbing material 4 is formed to have a U-shaped cross section, so that the opposing plate portion of the plate-shaped sound-absorbing material is elastically fitted into the internal space of the main body 3. The parts 4b, 4b are integrally formed.

In another embodiment shown in FIG. 4, the plate-like sound absorbing material 4 is constructed in the shape of a corrugated plate, and portions 4b, 4b that elastically fit into the internal space of the main body 3 are integrally formed with corrugated portions at both ends. It is something that

Another embodiment shown in FIG.
It is U-shaped and is configured to protrude close to the connecting plate portion of the main body 3.

In another embodiment shown in FIG. 6, the sound absorbing material portions 4a, 4a that cover the surfaces of the flange portions 3a, 3a in the embodiment are configured in an L-shape so as to also cover the joint surfaces of the flange portions 3a, 3a. This is what I did.

In any of the above embodiments and other embodiments, the elastic fitting not only facilitates the fixation of the plate-shaped sound absorbing material 4 to the main body 3, but also allows the portion 4a, which is elastically fitted to the main body 3, to 4a acts as a rib,
The rigidity of the plate-shaped sound absorbing material 4 can be increased.

Furthermore, the present invention may be implemented as follows.

As a means for fixing the plate-shaped sound absorbing material 4 to the main body 3, means using only adhesive, means using only elastic fitting,
Adopt pinning means.

The filled sound-absorbing material 5 is fixed by being pressed by the plate-shaped sound-absorbing material 4.

This is carried out without filling the sound absorbing material 5.
