[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a lightweight, high-strength, non-combustible partitioning sheet made by attaching an inorganic fiber board with a easily cut metal foil on the back surface, a thin gypsum board, or a low-density silica board to the back surface of the panel surface steel sheet. It's about panels.

[0002]

[Prior art]

 As the partition panel, a paper honeycomb structure is used as the core material, and steel plates are attached to both sides of the paper honeycomb structure. As a non-combustible partition panel, a gypsum board laminated to the back side of the panel surface steel sheet is often used. However, the one using a paper honeycomb has the drawbacks of being light, strong, inexpensive, flammable, and low in sound insulation. A honeycomb structure made of asbestos paper or aluminum foil was put on the market to eliminate the flammability of paper honeycomb, but it is mostly used because of its high price, pollution problems, and poor insulation performance. It has not been. On the other hand, those using gypsum board are inexpensive, non-flammable, and have high sound insulation performance, but have the drawback of being heavy. Due to this drawback, it is difficult to handle such as transportation, mounting, and removal, and immediate improvement is required.

[0003]

[Problems to be solved by the device]

 The problem to be solved is to solve each of the drawbacks of the above-mentioned current panel, a partition panel that is lightweight, non-combustible, high-strength, high insulation performance, inexpensive, easy to cut the core material, and easy to assemble the panel. Is to provide.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a high density but lightweight inorganic fiber board with a metal foil on the back, or a thin gypsum board with metal foil on the back, or a metal on the back. A partition panel is constructed by laminating a foil with a low-density silica sheet on the back side of the panel surface steel sheet. The inorganic fiber board is a molded board mainly made of glass wool, rock wool or ceramic wool.

High density inorganic fiber board with metal foil on the back, thin gypsum board with metal foil on the back, or low density silica sheet with metal foil on the back, etc. Compared with those with no metal foil on the back and those with steel sheet on the surface, the weight increase is very small, but the bending strength due to the load from the front side increases significantly. Therefore, the partition panel composed of such a combination plate is lightweight but has sufficient strength.

Although it is conceivable to replace the metal foil in the present invention with another material such as a metal net or a glass cloth, it is possible to bond the metal foil with a high density inorganic fiber board, gypsum board or low density silica board. There is a problem, and there is also a problem with the strength of the product itself, and it is practically inappropriate for use. Also, when a metal thin plate is used instead of a metal foil, there is no problem in strength, but it is difficult to process the core material described below, which leads to an increase in weight and cost, which is also inappropriate. In the present invention, a metal foil having a thickness of 0.03 mm to 0.15 mm is used.

A high-density inorganic fiber board with a metal foil on the back side can be easily cut with a cutter knife or the like, and a thin gypsum board with a metal foil on the back surface or a low-density silica board is also compared. Since it can be easily cut, there are mounting parts inside the panel, and when manufacturing panels of various sizes, it can be easily processed into the required shape and size.

[0008]

[Action]

 When a load is applied to the inorganic fiber board, gypsum board, or silica board with the metal foil on the back side, and when the side with the metal foil becomes the compression side, there is almost no effect of the metal foil on the strength, but it is actually applied to the panel surface. Since the load is applied almost inward, in the panel of the present invention, a compressive force is applied to the panel surface steel plate by bending, and the inorganic fiber board, gypsum board, or silica board on the backside is covered with the metal foil. Is on the tension side and the force is mainly applied to the metal foil. In this case, tensile stress is generated in the metal foil, but buckling does not occur due to the tensile force, and it is possible to withstand a large load. Also, when reinforcing ribs are inserted inside, the ribs and core material are bonded together via metal foil, so the bonding strength is greater than when the ribs and the inorganic fiber molded plate are directly bonded without foil. However, this is another factor that improves the strength of the entire panel.

【Example】

 FIG. 1 is a sectional view taken along the line A-A in FIG. 2 according to an embodiment of the present invention, in which 2 is a panel surface steel plate, 3 is a metal foil, 4 is an inorganic material forming plate, 5 is a pillar, and 6 is a joint part. Is.

The embodiment of FIG. 1 has a structure in which a high-density inorganic fiber board having a metal foil on the back surface is stretched on the back side of a panel surface steel plate, that is, a panel surface composite plate A is pierced on a pillar 5. However, the strength of the panel surface composite board is a very important factor in this structure. Regarding this strength, there are three types of panel surface composite board B, which is the most commonly used gypsum board on the back side of the panel surface steel sheet, and high density inorganic fiber composite board C, which has no metal foil on the back surface. Table 1 shows the results of comparison tests of strength using test pieces. The test piece had a surface steel plate thickness of 0.6 mm, the metal foil had a thickness of 0.06 mm, and had a total thickness of 12.6 mm, a width of 150 mm, and the distance between fulcrums at the load test was 420 mm.

[0011]

[Table 1]

As is clear from Table 1, the composite plate A according to the present invention has a very high strength as compared with the composite plate B of the type most used at present, and the back surface as compared with the composite plate C. It can be seen that the effect of the stretched metal foil on the strength is very large. The composite plate D in which a metal foil was put on the back surface of the gypsum board of the composite plate B showed almost the same strength as the composite plate A.

FIG. 2 shows a state in which the room is partitioned using the partition panel 1 of the present invention.

The embodiment shown in FIG. 3 is an integral type partition panel body mainly composed of a panel surface composite plate A type or a composite plate D type according to the present invention. The lighter weight and increased strength make such a panel easier to handle.

In the embodiment shown in FIG. 4, a reinforcing rib 7 is inserted inside the panel and a space is filled with a heat insulating and sound absorbing material 9. The reinforcing ribs 7 are usually made by cutting a high-density inorganic fiber board, but since the reinforcing ribs 7 are adhesively bonded to the metal foil 3, the effect of the ribs is sufficiently exhibited. Further, in the panel having this structure, the thickness of the panel surface composite plate can be further reduced by reducing the pitch of the reinforcing ribs 7.

In order to improve the sound absorbing effect of the panel shown in FIG. 5, holes are made in the panel surface steel plate 2, the inorganic material forming plate 4, and the metal foil 3, and the space inside is filled with the heat insulating and sound absorbing material 9. It is a thing.

[0017]

[Effect of device]

 As described above, the partition panel of the present invention cannot be used for this purpose due to its strength because it is made of an inorganic fiber board or a gypsum board attached to the back side of the surface steel sheet and a metal foil attached to the back side of the panel. In addition, it becomes possible to use a thin, high-density inorganic fiber board alone, and in the case of gypsum board, the board thickness can be made thinner, and the strength is higher than conventional ones. It is a non-combustible partition panel that can be manufactured and is easy to transport and handle. In addition, rock wool molded board, gypsum board or calcareous board used as the inorganic material molding board used in this panel has a radiant heat shielding effect of metal foil and has a considerable fire resistance. Therefore, this panel can be a light and high performance alternative to the non-combustible partition panel of heavy gypsum board core, which currently has practically only one type.
