This wall material consists of two layers of sound-absorbing material, especially a core material made of porous material such as mineral wool, sandwiched between two outer panels, and one layer of sound-absorbing material bonded to each outer panel. be. The two outer covering plates are connected to each other at least at both edges so that a gap is formed between the two core layers.

グ繊維などの鉱質綿を使用することができる。 Sandwich-shaped wall materials are used for partition walls, especially removable ones for offices, partition walls for railway vehicles, and partition walls called bulkheads that partition inside ships. The components of such partition walls or bulkheads need to be thin to save space, but they also need to be strong and have high soundproofing properties. The most commonly used wall material is one in which a core plate, particularly a porous material, is filled between two outer cover plates. As the porous material it is possible to use, for example, mineral wool, such as glass wool, rock wool or slag fibers, with a bulk density of at least about 50 Kg% m 3 and a binder content of at least about 0.5% by weight.

ある。 Partition walls or bulkheads constructed from such wall materials of suitable dimensions, for example 600 mm x 2400 mm x 50 mm (thickness), are sufficiently durable but do not have sufficient soundproofing properties. Therefore, a method has been proposed in which the core plate is made of two layers of porous material. Two core layers are separated by a spacer, and an outer cover plate is attached to each outer surface. This spacer forms a gap between the core material layers. These voids improve the soundproofing properties, but on the other hand, the strength is unduly reduced. This is because the core material layer transmits very little compressive force or resultant stress between the covering plates.

きる。 An object of the present invention is to provide a sandwich wall material that has sufficient strength and has higher soundproofing properties than conventional sandwich wall materials of comparable thickness. This object is achieved in the present invention by providing a reinforcing layer of paper, foil, fiber material, etc. on the entire or part of the surface of the core layer facing the internal void. Since this reinforcing layer can absorb tension, basically a wall material with excellent strength is obtained. At the same time, the sound insulation is increased and the resonant frequencies of the wall material are significantly damped. By using metal foil such as aluminum for the reinforcing layer, it is possible to improve the fire resistance of the wall material, which is a problem especially when used for bulkheads inside ships, and at the same time, it is possible to improve the fire resistance of the wall material even if a fire breaks out on one side of the wall material. It is possible to keep the temperature rise on the opposite side low. Moreover, if glass fiber is used, fireproofing properties can be improved, and at the same time, adhesion to the core layer becomes easier. Moreover, the soundproofing properties at the upper limit resonance frequency of the wall material can be improved compared to the case where narrow strip-shaped mineral wool is used for the two core material layers.

れている。 FIG. 1 shows an embodiment of the wall material of the present invention, in which a core layer 2 is bonded to an outer cover plate 1.
This core material layer 2 is made of, for example, mineral cotton hardened with a binder, and can have a specific weight of about 150 kg/m 3 and a binder content of about 1% by weight. Edge pieces 3 are arranged along both side edges between the two outer cover plates 1, and grooves 4 of 15 mm x 15 mm are cut into the edge pieces 3 as necessary. The outer cover plate 1 and the edge piece 3 are attached by adhesive or other known methods. The edge piece 3 can be made of metal molding, wood, or mineral cotton impregnated with a binder such as phenol formaldehyde resin or water glass. The thickness of the edge piece 3 is greater than the total thickness of the core material layers 2, so that a gap 5 is formed between the core material layers 2. For example, the dimensions of the edge piece 3 are 47.4 mm x 47.4 mm, and the thickness of each core layer 2 is 22 mm.
It can be done. For the outer cover plate 1, a steel plate with a thickness of 0.7 mm can be used, but plastic or wooden ones can also be used. When the core material layer 2 is constructed using mineral cotton hardened with a binder, it can be formed into a plate shape in which the fibers are arranged parallel to the surface of the outer cover plate 1. The core material layer 2 is also made of a laminate obtained by rotating each band of mineral cotton hardened with a binder so that the direction of the fibers is perpendicular to the surface of the outer cover plate. It can also be configured. This laminate may be arranged vertically or horizontally in the wall material.
The voids 5 at the top and/or bottom of each wall material can be closed with mineral wool. A reinforcing layer 6 made of paper, plastic foil, metal foil, glass fiber, or the like is attached to the surface of each core layer 2 facing the void 5.

This shows the results measured based on the following. The area of the test wall was approximately 10.4 m 2 . FIG. 2 shows the sound attenuation characteristics of a wall assembled from known wall materials having voids 5 in decibels. FIG. 3 shows this as a curve.
The outer cover plate 1 is a steel plate with a thickness of 0.7 mm, on which mineral wool is laminated with a binder to a size of 47.4 mm x 47.4 mm x 2400 mm, and an edge piece 3 having a specific weight of about 300 Kg/m 3 is adhered. Each outer cover plate 1 has a specific weight of approximately 150Kg/m 3 ,
A core material layer 2 made of a mineral cotton laminate with a thickness of about 22 mm is adhered, and a gap with a width of about 22 mm is formed between both core material layers. A 15 mm x 30 mm x 1.5 mm steel pipe was inserted into the groove 4 and the individual wall members were connected to form a wall body. The measurement results were LabIa = 40 dB, total negative deviation = 11 dB, and Rm = 39.3 dB. At a resonance frequency of 125Hz, R was 15.8dB. Figures 4 and 5 show the results of similar measurements on the same walls as in Figures 2 and 3, but the only difference is that each core material facing the void 5 This is where lutex glass fibers are bonded to the surface of layer 2. The measurement results are LabIa=44dB,
The total negative deviation was 23 dB, and Rm was 40.1 dB.
At a resonance frequency of 125Hz, R was 22.8dB.
Figures 6 and 7 show the results of similar measurements made on walls similar to those in Figures 4 and 5, but in Figures 6 and 7, glass fibers were replaced. 0.05mm thick aluminum foil was used.
