Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a partition wall used as a partition to divide the inside of a building into several rooms. Regarding the unit.

0002

[Conventional technology]

Partition walls are installed to divide the inside of a building into several rooms. Ru. Traditionally, partition walls were constructed by assembling panels at the construction site. However, in recent years, from the viewpoint of labor saving and uniformity of products, it has become easier to manufacture products in factories. After the partition wall unit is constructed and transported to the construction site, it is installed in the building at the site. Development is provided. This partition wall unit has two or more panels made of plasterboard, etc. There are also three sheets pasted together and a sound absorbing material such as glass wool applied between them. Laminating multiple sheets like this is an attempt to obtain a specified thickness using a single sheet. , the required fire resistance/sound insulation performance and rigidity cannot be obtained, and the surface material has no finish. This is due to the fact that a material different from the base panel may be used. . Furthermore, in recent years, non-stud panels have been introduced that do not require the use of lightweight steel studs. This is compensated for by providing ribs that extend vertically (in the vertical direction when built in) on the flannel. A stronger version is also being developed.

[Problem that the idea aims to solve]

However, the various panels currently available are laminated and have poor sound insulation performance. The above sound insulation standards are met because the relationship between However, even higher sound insulation performance could not be achieved with the same plate thickness. Here, the inventor found that there are differences in sound insulation performance depending on the way the panels are pasted together. I started it. The present invention was developed in view of these circumstances, and its problem is to The object of the present invention is to provide a partition wall unit with higher sound insulation performance than conventional technologies.

【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. However, books The dimensions, materials, shapes, relative positions, etc. of the components described in the examples are particularly Unless there is a specific statement, the scope of this invention is limited to those only. It's not, it's just an illustrative example.

[0006] First, the configuration of the partition wall unit according to the present invention will be explained using FIGS. 1 to 3. explain. The partition wall unit 1 was manufactured in a factory and is shown in Figures 1 and 2. Two panels (plate-like bodies) 2 of the same size facing each other with a certain interval between them, and It is generally composed of a sound absorbing material 3 interposed within each panel 2. Both panels 2, the edges of multiple inorganic fiber-reinforced gypsum boards that are rectangular in side view are butted against each other. They are connected together to form a predetermined size. Regarding such connection method, conventional technology etc., may be carried out by any suitable method for implementing the present invention. Said two panels In order to connect through a predetermined interval, use the connecting fittings attached to the side ends as shown in Figure 3. This is done by 8. The connection fittings 8 extend from the upper end to the lower end of each panel 2. It is a rod-shaped body with a U-shaped cross section, and the outer surface of the part corresponding to the vertical bar of the U-shape is facing the side edges of each panel 2 in the direction in which the partition wall unit 1 is installed. On the opposing surface 9a of the mounting protrusion 9 extending in the vertical direction, there is a portion corresponding to both horizontal bars of the U-shape. The outer surface of the holder is fixed. In addition, on the outside surface of the part corresponding to the vertical bar of the U-shape The construction bolts 10 are provided at regular intervals in the longitudinal direction. Each of the panels 2 is provided on the outer surface (the surface opposite to the facing surface) of the both panels 2. Surface materials 4 of the same height and width are each attached separately using vinyl acetate adhesive. Ru. Each surface material 4 consists of a plurality of quasi-noncombustible gypsum boards with continuous seams extending horizontally. Make sure that each seam is staggered in the vertical direction, and Protrude so that the seams extending in the direction do not overlap with the seams of each of the inorganic fiber reinforced gypsum boards. They are assembled and connected to the required size, and each joint is treated with putty. There is. Regarding such connection methods, conventional techniques and other suitable methods for implementing the present invention may also be used. This can be done by Further, on the opposing surfaces of each panel 2, there is a The ribs (stiffeners) 5 are arranged at equal intervals in the horizontal direction, and the ribs 5 are in contact with each other. A plurality of them are provided alternately on the opposing surfaces of each panel 2 to prevent this from happening. The relevant The panel 5 has an inorganic fiber having the same length as the height of each panel 2 and a rectangular cross section. It is made of reinforced gypsum board and has a height smaller than the interval between each panel 2. has. Therefore, the rib 5 attached to one panel 2 comes into contact with the other panel 2. Never. In addition, in order to attach each of the ribs 5 to the panel 2 separately, tap the This is done using screws (not shown). The sound absorbing material 3 is made by stacking two sheets of glass wool of the same size, and the above-mentioned The ribs 5 are interposed between the panels 2 as shown in FIG. Since they are provided on opposing surfaces of each panel 2, the overall shape is a corrugated plate. . Further, the upper and lower edges and side edges of the partition wall unit 1 are provided with locks. The partition wall unit 1 is filled with a wall (not shown), and the side edges of the partition wall unit 1 are filled with a wall (not shown) as shown in FIG. It is sound-insulated using an acrylic sealant 7. To erect the partition wall unit 1, a runner etc. similar to the conventional technology is used. Just do it.

[0007] Next, the effects of the partition wall unit 1 configured as above will be explained. As shown in the test results described later, the partition wall unit 1 is superior to the conventional technology. The sound insulation performance can be improved or the board thickness can be reduced while maintaining the same sound insulation performance. Furthermore, in this embodiment, ribs 5 are provided on opposing surfaces of each panel 2. Therefore, it can be used as a non-stud panel 2. In addition, since it is manufactured in a factory, the product is uniform and the construction period is shortened. It is possible to reduce labor costs, reduce labor costs, etc.

[0008] Note that although the partition wall unit 1 according to this embodiment has the above configuration, the present invention The present invention does not intend to limit the scope of It is possible to have a suitable configuration for implementing the present invention, such as a plant or the like.

[0009] Finally, Figure 4 is used to describe the experimental results of the partition wall unit 1 configured as described above. I will explain. a. Test specimen dimensions. Overall dimensions: height 3000mm, width 3700mm, thickness 168mm. Dimensions of panel 2...thickness 21mm. Dimensions of sound absorbing material 3: 2 layers with a thickness of 25 mm and a unit weight of 32 kg/m3 thing. Dimensions of surface material 4...thickness 12 mm. b.Test method Sound transmission loss test method conducted in accordance with JIS A 1416. c. Test results The test results shown in FIG. 4 were obtained (○ indicates each center circumference of the partition wall 1 according to this example). Indicates the sound transmission loss at the wave number, and ● indicates each center of the partition wall unit according to the conventional example. represents the sound transmission loss in frequency). According to the test results, as shown in Figure 4, all frequencies above 400Hz Full-contact type partition wall unit (surface material 4, panel 2, ribs 5, suction The sound transmission loss is larger than that of sound material 3 and rock wool 6, which have the same dimensions. ing. Therefore, this test revealed that the sound insulation performance is superior to that of the full-surface contact type. Karu.
