Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior inorganic surface material-applied panel for forming an exterior portion of a building such as a prefab house.

[0002]

2. Description of the Related Art In recent years, for example, in the construction of houses, a prefabricated construction method has been widely adopted in which a house is constructed by assembling a wall panel, a roof panel, etc. manufactured in advance in a factory at a construction site. By the way, as a panel used in such a prefab construction method, a panel in which a wood surface material made of plywood or the like is attached to both or one of the frame bodies assembled in a rectangular contour by a core material is generally used.

[0003]

However, in the panel in which the wooden surface material is adhered to the frame body, the following disadvantage occurs when the exterior surface is formed using this panel. That is, when this is used as an exterior panel, after assembling these on the site, a waterproof layer made of a waterproof sheet or the like is attached to the surface to be the exterior part as a finish, and then the furring strip is attached on it. After that, finishing treatments such as siding, lathing, mortar coating, and painting are performed. However, since such finishing is performed on site, it becomes a factor of prolonging the construction period. When this panel is used as an outer wall panel, it is usually necessary to impart structural strength, fireproofness, sound insulation, waterproofness, and aesthetics to the panel, but the panel satisfies these performances. Therefore, it is necessary to perform the above-described exterior finishing treatment on the exterior side surface on site, which is a major cause of impairing the shortening of the construction period.

The present invention has been made in view of the above circumstances. An object of the present invention is to reduce the finishing time on site and shorten the construction period, and moreover, a plywood-attached panel without attaching plywood. With structural strength equal to or higher than
Another object of the present invention is to provide an exterior inorganic surface material-attached panel that does not require on-site waterproofing, that is, has excellent structural strength, fireproofness, sound insulation, and waterproofness.

[0005]

In the panel for attaching an inorganic surface material for exterior of the present invention, an inorganic surface material is attached to the surface on the exterior side,
The inorganic surface material is subjected to a sealer treatment having waterproofness, which is a means for solving the above problems.

[0006]

According to the exterior inorganic surface material-attached panel of the present invention, since the inorganic surface material is adhered to the exterior surface of a building such as a house, the surface material has structural strength, fire resistance and sound insulation. Being superior, it eliminates the need for structural plywood and fire-base treatments such as siding and mortar. In addition, since the inorganic face material is subjected to a waterproof sealer treatment, the face material itself has a waterproof property, and therefore, there is no need to carry out the waterproof treatment on site as in the conventional case.

[0007]

FIG. 1 shows an embodiment in which the panel for attaching an exterior inorganic surface material of the present invention is applied to a panel for an outer wall of a house. Reference numeral 1 in the figure denotes a panel for an outer wall (hereinafter abbreviated as a panel Yes). In this panel 1, reinforcing core members 2c are arranged vertically and horizontally inside a frame body 2 in which vertical core members 2a, 2a and horizontal core members 2b, 2b are assembled into a rectangular contour. The frame 3 is made up of the above, and the inorganic surface materials 4 and 4 adhered to both side surfaces of the frame 3, and the frame 3 is filled with a heat insulating material 5 such as glass wool, whereby a panel is formed. The heat insulation performance and sound insulation performance of No. 1 are improved. Further, the panel 1 is manufactured in advance in a factory by having the above-mentioned simple structure.

As the inorganic surface material 4, for example, JIS-A-
5422 asbestos cement siding and JIS-A-
Ceramic-based plate materials such as 5429 slag gypsum-based cement plate are preferably used. Here, JIS-A-5422 is a plate-shaped product obtained by appropriately mixing asbestos, cement, calcareous raw material, siliceous raw material, slag, gypsum, etc., and JIS-A-5422. The object is a plate body formed by slag, gypsum as a binder, and glass fiber, asbestos, etc. as a reinforcing material. In addition, inorganic materials such as fly ash, slag, cement as the main component, fiber mixed as reinforcing material into a plate shape, and lightweight concrete (ALC) board with air bubbles and lightweight aggregates are also used. Of course, it can be suitably used as the face material 4. Specific examples of such an inorganic surface material 4 include a fiber-containing fly ash slag cement board (manufactured by Ube Board Co., Ltd.) and a fiber-containing slag gypsum board (manufactured by Mitsubishi Cement Building Materials Co., Ltd.).

Further, such inorganic surface materials 4 and 4 have structural strength, fireproofness and sound insulation desired as surface materials for wall panels, and their surfaces are sufficiently smooth as adhesive surfaces and various finishing ground surfaces. And has the following properties. Water absorption rate: 20% or less, dimensional change rate upon water absorption: 0.10% or less, bending strength: 200 kgf / cm2 or more, tensile strength: 10
0 kgf / cm2 or more, plane tensile strength; 15 kgf / cm2 or more.

Further, as for the attachment of the inorganic surface material 4 to the frame 3, a known adhesive which has been used for adhesion of conventional wood surface materials is used, but it is excellent in curing speed and adhesion workability. It is more preferable to use a liquid fractional coating type adhesive.
Here, the two-liquid separation coating adhesive is an adhesive consisting of a few components, and the three-component adhesive mixes two of those components before bonding and treats them as apparently two components when applying the adhesive. It is a thing. These are generally called honeymoon type adhesives or two-liquid non-mixed type and are commercially available. For example, acrylic adhesives such as SGA,
It contains a gelling accelerator, a reaction catalyst, and an adhesive of the type that uses a reaction initiator as a primer.

That is, these are those that cannot be mixed or need to be mixed before bonding because they are too fast to be cured, and are used only after mixing for bonding. In addition, specifically, an acrylic adhesive (trade name “Diabond SG-350”), a modified SBR adhesive (trade name “HB-10”; manufactured by Konishi Co., Ltd.), an acrylate adhesive (trade name) "Multibond 330" manufactured by Nippon Loctite Co., Ltd.) is preferably used.

The outer surface of the inorganic surface material 4 disposed on the exterior side among the inorganic surface materials 4 and 4 is previously subjected to a waterproof sealer treatment by the factory or the like. Here, as the sealer treatment method, there is a method of applying a permeation waterproof material such as a silicone type, a silanol type, an acrylic type, an alkoxysilane type, a silane type, a urethane type by a roller method, a spray method, a flow coater method or the like. Adopted. When such a sealer treatment is performed, the surface layer of the inorganic surface material 4 is impregnated with the permeable waterproof material to form the sealer layer 6. By forming the sealer layer 6 as described above, the inorganic surface material 4 on the exterior side becomes waterproof, and thus the panel 1 is like a panel formed by pasting a conventional wood surface material. The work of attaching a waterproof layer made of a waterproof sheet after assembling on site is not necessary. Regarding the sealer processing, the framework 3
It may be done before or after the inorganic surface material 4 is attached to the frame 3, or after it is attached to the framework 3, and the method which is advantageous in the process can be selected.

In order to form the outer wall of a house using the panel 1 having such a structure, for example, as shown in FIG.
And a plurality of panels 1 ... Standing on the foundation 9 via the floor panel 8 and fixed to the anchor bolts 10 on the foundation 9. Then, finish processing such as spraying and painting is performed on the exterior surface to complete the outer wall surface. Further, on the inner surface side of the panel 1, it is possible to directly attach a cloth without attaching a gypsum board as a base for cloth attachment as in the conventional case.
As for the joining between the panels 1 and 1, known means such as nailing, bonding, joining with a joining metal or the like is adopted.

In such a panel 1, since the inorganic surface material 4 is excellent in fireproofing and sound insulation, it is not necessary to additionally attach a gypsum board to the inner wall side, and the inorganic surface material 4 on the exterior side is also provided. Since the waterproof property is provided by the sealer layer 6 by the waterproof sealer treatment, there is no need to treat a waterproof sheet or a fireproof base on site as in the past, and therefore construction on site is much easier than before. It becomes easier, and the construction period can be greatly shortened and the cost can be reduced.

In the above-mentioned embodiment, an example of applying the exterior inorganic surface material-attached panel of the present invention to the outer wall panel is shown.
Of course, the panel of the present invention can be applied to the roof of a house.

[0016]

As described above, the panel for attaching an exterior inorganic surface material of the present invention has a simple structure in which an inorganic surface material subjected to a sealer treatment having waterproof property is attached to a frame. It can be easily produced in the same process as a plywood panel at the factory, and the inorganic surface material is excellent in fireproofing and sound insulation and has high structural strength. No need to process,
Construction on site is much easier than before. Further, since the inorganic face material is previously subjected to waterproof sealer treatment, the face material itself becomes waterproof, thus eliminating the trouble of performing the waterproof treatment on site as in the conventional case. It is a thing. Therefore, according to the exterior inorganic surface material-attached panel of the present invention, it is possible to reduce the construction time at the site, reduce the labor cost at the site construction, and significantly shorten the construction period.
