Description

[Detailed description of the invention] This invention is a structural plywood board with a mortar layer attached to the front side and a sound absorbing material layer attached to the back side. The present invention relates to an improvement in a prefabricated soundproof partition that can be assembled into a desired size by connecting the respective ends of adjacent panel bodies.

The main purpose of the present invention is that since conventionally, each of the opposing side plates and the connecting member (shaped steel is used to provide the required shape-retaining strength) were rigidly connected, the incident sound from the sound source side could not be transmitted to the connecting member. The sound insulation performance deteriorates due to the bridging phenomenon at the edge of the panel circumference where the sound enters the receiving side directly through the member, and the center of the panel due to the fact that the opposing side plate was conventionally made of plasterboard with a small mass. In view of the insufficient sound insulation performance of the bridge, we decided to consider the connection structure between the opposing side panels and the material of the side panels.While the workability remains the same as before, we have improved the sound insulation performance by eliminating the bridging phenomenon mentioned above. The point is that we are trying to improve the quality of our products.

First, embodiments of the present invention will be described below.

Figure 1 shows the connecting structure of panel bodies A and A that are adjacent in the vertical direction, and Figure 2 shows the connection structure of panel bodies A and A that are adjacent in the horizontal direction.
This shows the connection structure between them.

X indicates the sound source side, and Y indicates the sound receiving side.

One panel body A is made by applying white mortar to the front side of structural plywood 1 to form a mortar layer 2, and adhering a sound absorbing material layer 3 such as glass fiber or cellulose fiber to the back side. A perforated plate material 4 such as perforated veneer is stretched on the back surface of the material layer 3, and a fixed connection made of lightweight steel is attached to the back surface of the structural plywood 1 at the circumferential end via a sound absorbing material 5 made of high-density glass fiber. Fix the member 6 with the self-screw 7,
A plaster board 10 arranged to form an air layer 9 on the back of the sound absorbing material layer 3 has a circumferential end that can be fixedly connected to the member 6 at a location corresponding to the fixed connection member 6. A fixed connection member 11 made of lightweight steel, which is symmetrical to the member 6, is fixed with a self-screw 13 through a sound absorbing material 12 made of high-density glass fiber.

and a nut 15 for fixed connection.

In addition, 8 and 8 are panel bodies A arranged side by side in the horizontal direction and the vertical direction.
, This is a joint treatment material for the butt joint of A.

In one panel body A, the connecting members 6, 11 are positioned to protrude outward from the peripheral edge at the upper end and one end in the lateral direction, and the connecting members 6, 11 are located at the lower end and the other end in the lateral direction. 11 is recessed inward from the peripheral edge,
Therefore, the respective ends of adjacent panel bodies A and A are inserted and fitted together at the construction site.

In order to maintain the adjacent panel bodies A, A, etc. in the required posture, the adjacent panels should be connected and joined by appropriate means, and in addition, the panel bodies should be attached to the floor, ceiling, and side walls of the building. A: The outer periphery of the entire group shall be connected and joined by appropriate means.

For reference, to give an example of the dimensional relationship, the thickness of the mortar layer 2 is 2 to 10 mm, and the thickness of the connecting members 6 and 11 is 1 mm.

The thickness of the Mn1 porous member 4 is 9 to 12, and the aperture ratio of the porous member 4 is 20 to 12.
In 85% of cases, the pore size is 3 to 5 rML.

As shown in the above embodiments, the characteristic structure of the prefabricated soundproof partition according to the present invention is that the mortar layer 2 is adhered to the front side of the structural plywood 1, and the sound absorbing material layer 3 is attached to the back side.
A plurality of panel bodies A are formed by adhering them to each other, and a perforated plate material 4 is attached to the back side of each panel body. In a prefabricated soundproof partition that is assembled into a desired size by connecting sections, a high-density glass fiber sound absorbing material 5 is applied to the back surface of the structural plywood 1 at the circumferential end of the panel body A. fixing the fixed connection member 6 through the porous plate material 4, and arranging boards 10 in parallel at intervals on the back of the porous plate material 4;
A fixed connection member 11 protruding toward the porous plate material 4 is fixed to the circumferential end of the board 10 with respect to the fixed connection member 6 through a sound absorbing material 12 made of high-density glass fiber. , 11 to form an air layer 9 between the perforated plate material 4 and the board 10.Furthermore, at the upper end of one panel body A and at one end in the lateral direction, the connecting members 6, 11 are connected to the circumferential side. Positioned to protrude outward from the edge,
In addition, at the lower end and the other end in the lateral direction, the connecting members 6, 11 are recessed inward from the peripheral edge, and the respective ends of the adjacent panel bodies A, A are inserted and connected to each other by fitting. This configuration enables the following effects to be achieved.

That is, on the side of the sound absorbing material layer 3, the structural plywood 1 and the connecting member 6 are fixed with a high-density glass fiber sound absorbing material 5 having extremely high sound absorbing properties interposed between them, and an air layer is formed. Also on the side of the board 10 for forming the sound source 9, the board 10 and the connecting member 11 are fixed with a high-density glass fiber sound absorbing material 12 interposed between them. The sound is greatly attenuated by the circular high-density glass fiber sound absorbing materials 5 and 12 at the circumferential end (prevention of bridging phenomenon), and the passage of sound to the sound receiving side can be sufficiently suppressed. .

In addition, the surface layer on the sound source side of the sound absorbing material layer 3 is made of structural plywood 1.
Since it has a two-layer structure with the mortar layer 2 and the mortar layer 2, it is possible to increase the mass, so that sufficient sound insulation performance can be expected even in the central part.

In addition, a perforated plate material 4 is attached to the back side of the sound absorbing material layer 3,
While ensuring the shape of the sound-absorbing material layer 3, the porous plate material 4 does not act as a complete sound insulating wall, and the air layer 9 exhibits a good attenuation effect on low-frequency sounds passing through the holes of the porous plate material 4. It will be done.

The synergistic effect of the above makes it possible to achieve extremely high sound insulation performance as a whole, and since it can be constructed by simply assembling prefabricated products on-site, construction can be done economically without complicating the work. There is an advantage.
