Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a composite panel made of flash (1').

Conventionally, a front plate (2) was attached to the screen of the JIJ frame core (1).
) In the conventional example, the inside is filled with shirasu wool (3), so it has heat insulation and sound insulation properties, but the front plate (2)
Since there is nothing inside the central part of the board to support the board (2), there is a disadvantage that the surface of the N-curved board (2) becomes uneven and no longer flat, and there is no pressure on the top board (2). It has the disadvantage that it becomes flat when exposed to water. In addition, if a rigid core material such as parallel plywood or timber similar to the frame core material (1) is installed between the frame core materials (1) in order to prevent this flattening, there is a drawback that the sound insulation performance will deteriorate due to solid propagation seams. be.

The present invention has been made in view of the above points, and an object of the present invention is to provide a composite panel that has excellent sound insulation properties, has a flat surface, and has a beautiful appearance.

The following is a detailed explanation of "Kihatsu" using examples.

ill is a rectangular frame core material made of rigid material such as parallel plywood or exposed wood, and a surface plate (2) such as board beam plywood is laminated on both sides of the frame core material 0). be. The space surrounded by the frame core material f+) and the surface plate (2) is filled with shirasu wool (3). Such glass wool (3)
The density is 1d2sh/door. In addition, (4) is a rectangular bar-shaped auxiliary core formed of a rubber elastic body, which is installed in the same way as the surface plate (2) and tilted approximately at the center, and which is installed with the frame core open (0). be. This auxiliary core material (4) and the surface plate (2) are connected to each other with adhesive 11-.

Figures 3 (a) (I)) (c) and Figure 4 (Q) show other examples of the description. As shown in Figure 2713 (a), a plurality of auxiliary cores (4) are installed between the surface plates (2),
As shown in Figure 3 (b), the front side (5 (2) has an auxiliary core (4)
Figure 3 (C)
By including Gl and M1!, a beautiful outer n+', t with changes as shown in Fig. 4 can be obtained.

As mentioned above, the wood is filled with glass wool in the space surrounded by the front panel and the frame core, so it not only has sound insulation properties, but also has an auxiliary core inside the front panel. Therefore, as shown in Table 1, it can support the center part of the 11-board board, the surface is flat and has a beautiful finish, and it will not flatten even if the compression is uneven, and the auxiliary core is made of elastic material so it is solid. It can prevent propagated sound and has excellent sound insulation even if an auxiliary core TL is installed.
