[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a surface finishing structure applied to the outer surface of a wall formed by arranging a number of ALC panels and a cover sheet material used for the structure.

[0002]

[Prior art]

 In recent years, ALC panels, which are excellent in lightweight, fire resistance, heat insulation, sound insulation and economy, have been increasingly used as outer walls of buildings.

The ALC panel is formed in a rectangular shape having a certain area, and each edge is provided with a tapered surface that becomes thinner toward the edge in consideration of filling a seal material. I am allowed.

When the outer wall of a building is formed using the ALC panel, the following steps (1) to (2) are performed. ． A large number of ALC panels are properly arranged on a steel aggregate assembled in a predetermined shape, that is, arranged so as to abut each other with a minute gap provided between the edges of the ALC panels, and bolted. In this state, a recess having a V-shaped cross section is formed by the tapered surfaces of the adjacent ALC panels. ． Next, a sealing material is filled in the bottom of the above-mentioned recessed portion, and further, cement is applied to the recessed portion so as to cover the sealing material until it becomes substantially flush with the surface of the ALC panel (hereinafter, the sealing material and The recessed part filled with cement is called the joint treatment part). Note that the joint treatment is not limited to this because there are other methods. ． Finally, if necessary, a coating material for makeup is sprayed on to complete the outer wall of the building.

As described above, when the ALC panel is used, the outer wall of the building can be completed relatively easily, but the outer wall formed by this method has the following problems. A. When the wet method of spraying the coating material is adopted locally, there is a problem that it takes a lot of time to finish because the drying time is required. B. Regardless of whether it is the wet method or the dry method using a pre-painted ALC panel, there is a problem that when the joint treatment portion is cracked due to the stress acting on the building, it looks very unattractive. C. When a crack occurs in the joint treatment area, rainwater invades from the crack, which causes corrosion of the steel aggregate, resulting in a problem that the strength of the building itself decreases. D. The painted surface is uniform and cannot be designed to be excellent.

[0006] In recent years, in this type of industry, the outer wall surface formed of ALC panels can be finished in a short time, and no bad-looking cracks or the like are generated on the outer wall surface. It is desired to develop a surface finish structure for the outer wall of the ALC that can generate a good construction surface without causing any generation, and a cover sheet material used for the structure.

[Action]

 This device works as follows.

When the surface finish structure of the ALC outer wall surface according to the present invention is used, A. The cover sheet material 3 of the present invention is manufactured in advance in a factory, and by using this locally, the dry method can be used, so that the drying time unlike the wet method is unnecessary, and as a result, the finishing is relatively short. Can be done in time. B. Even if stress is applied to the structure and the joint treatment portion 2 is cracked, the joint treatment portion 2 is covered with the covering sheet material 3 and does not affect the appearance. Immediately, you can secure a beautiful condition when finishing for a long time. C. Even if the joint treatment portion 2 is cracked after finishing, the joint treatment portion 2 is covered with the covering sheet material 3 and the small gap between the adjacent covering sheet materials 3 and 3 is waterproof. Since the sealing material 4 is filled to cover the entire outer wall surface, rainwater penetrates directly or indirectly from the cracked portion of the joint treatment portion 2 or the air bubbles of the ALC panels 1 and 1 to the steel aggregate. There is no such thing. Therefore, the corrosion of the steel aggregate caused by the intrusion of rainwater will not occur, and the decrease in strength of the building itself due to this will be completely prevented. Since the cover sheet material 3 has elasticity and the seal material 4 has excellent stretchability, even if the ALC panels 1 and 1 are displaced from each other, the seal material 4 may be broken or the cover sheet material may be removed. It is unlikely that the 3 will peel off, and the above condition can be secured for a long time. D. Since the waterproof thin film layer 31b (the surface layer 31 in another device) is transparent or translucent, the printed part can be seen through the waterproof thin film layer 31b (the surface layer 31 in another device). If, for example, a surface photograph of marble, granite, or the like is formed by printing, the construction surface can be made excellent in design.

In this embodiment, as shown in FIGS. 1 and 2, a plurality of ALC panels 1 are arranged to form the outer wall surface of the building, and the surface finishing structure of the present invention is adopted. [Overall Structure] As shown in FIG. 1 and FIG. 2, a large number of ALC panels 1 are arrayed and fixed to a steel frame F that constitutes a building by bolt nuts (not shown), and joints between adjacent ALC panels 1 and 1 are fixed. A covering sheet material 3 is attached to the ALC panel 1 with an adhesive 5 so as to cover the processing section 2, and a small gap between the buttings of the covering sheet materials 3 and 3 is filled with a sealing material 4. It is configured. In this embodiment, ALC panels 1 having a width of 600 mm are vertically arranged as shown in FIG. [About Covering Sheet Material 3] (Aspect 1 of Covering Sheet Material 3) As shown in FIG. 3, the covering sheet material 3 includes a sheet-shaped base material 30, a surface layer 31, and an intermediate layer 32 between them. It is integrated and has elasticity as a whole. Here, the cover sheet material 3 is manufactured in advance in a factory to have a vertical and horizontal dimensions of 594 mm and a thickness of 4 mm, and this is used at a construction site.

As the sheet base material 30, a woven cloth formed by weaving glass fibers is used. The sheet base material 30 is not limited to the one woven with glass fiber, and a material woven with resin fiber may be adopted, or may be formed by knitting these fibers. Further, it may be a resin sheet that is deformable and has a roughened surface.

As shown in FIG. 3, the surface layer 31 includes a flexible film 31a having a printed portion 31c on the surface side, and a transparent or translucent waterproof thin film layer 3 formed so as to cover the printed portion. 1b and.

The flexible film 31a can be made of, for example, a vinyl chloride-based resin, an acrylic-based resin, a polyester-based resin, a urethane-based resin, a silicon-based resin, or the like, while the waterproof thin film layer 31b is made of, for example, fluorine. It can be composed of a paint based on polyester, a paint based on polyester, a paint based on urethane, a paint based on silicon, or the like. When the waterproof thin film layer 31b is formed by coating a fluorine-based paint or an inorganic-based paint whose main component is organopolysiloxane, both of them have a weather resistance of about 20 years. In addition, the latter has excellent fire resistance.

Here, since the printing portion 31c can be visually recognized through the waterproof thin film layer 31b, a printing portion of an appropriate type (color printing of marble, granite, etc. is possible since printing technology has been established in recent years, By providing the flexible film 31a with any other material that can be photographed), the construction surface can be made excellent in design.

The intermediate layer 32 is formed by mixing an inorganic material (cement or silica is used) as a main material and a flexible resin material, and has a heat insulating property and a certain degree as a whole. It has elasticity.

Here, an example of the components of the inorganic material and the flexible resin material forming the intermediate layer 32 will be shown below. (A) Inorganic material component (powder) Special cement: 52% weight ratio Additive: 0.8% weight ratio Aggregate: 28% weight ratio Fine aggregate: 19.0% weight ratio Polymeric binder: 0.2% weight ratio (B) Components of flexible resin material (mixture) Special acrylic resin emulsion: 78% weight ratio Surfactant: 0.3% weight ratio Defoaming agent: 0.3% weight ratio Antiseptic / antifungal agent: 0.1% weight ratio Clay imparting agent: 2.0% weight ratio Water: 19.3% weight ratio (C) Mixing weight ratio of inorganic material: flexible resin material = 20: 7 The joint treatment section 2 covered with the covering sheet material 3 is filled with a sealing material 20 made of an acrylic or modified silicone resin on the back side.

The surface layer 31 and the intermediate layer 32 described above are preferably adhered using a waterproof acrylic adhesive, silicone adhesive, urethane adhesive or the like. [About Sealing Material 4] In order to prevent the sealing material 4 from being broken due to the mutual displacement of the ALC panels, it is necessary to use a material having excellent stretchability. The modified silicone type is used. In this embodiment, the width for filling the sealing material 4 is 6 mm and the thickness is 4 mm. [Adhesive 5] The adhesive 5 is preferably waterproof, and acrylic, silicone, urethane or the like can be used.

Next, a construction sequence for completing the surface finishing structure of the ALC outer wall surface of this embodiment will be described with reference to FIG. It is assumed that joint treatment has already been performed. First Step First, the adhesive 5 is applied to the surfaces of the ALC panel 1 and the cement 21 that form the outer wall, and then the adhesive sheet 5 is sequentially attached. At this time, as shown in FIGS. 1 and 2, the joint treatment section 2 is covered with the central portion of the cover sheet material 3. The adhesive 5 may be applied to the surface sheet material 3 side. Second step Next, the sealing material 4 is filled in the gap between the adjacent covering sheet materials 3 and 3 to complete the construction.

The surface finishing structure of the ALC outer wall surface of this embodiment has the above-mentioned structure, and since this structure can be constructed by the above-mentioned steps, it is as follows than the conventional surface finishing of the ALC outer wall surface. Is very good at. ． Since the joint treatment section 2 is covered with the cover sheet material 3, cracks and the like do not occur on the surface of the wall surface. Therefore, it looks good and rainwater does not enter inside the steel aggregate. ． The printing portion 31c formed on the flexible film 31a enables the entire wall surface to have a luxurious finish like marble or granite. ． Basically, only the attachment of the cover sheet material 3 is applied, so the work is completed very quickly. ． Since construction is simple, there is little difference depending on the skill of the builder, and the possibility of construction errors is extremely low. ． Since no paint or coating material is used at the construction site, there is no risk of fire and there is no danger to the health of the contractor. ． Since paints and coating materials are not used at the construction site, construction may be suspended due to odors (this situation may occur due to the notification from the Ministry of International Trade and Industry) and paints may adhere to buildings, vehicles, etc. around the site. There are no problems such as rusting, and there are almost no remaining cans or waste materials. ． Unlike tiles, etc., the cover sheet material 3 is light, so there is less risk of falling during construction, and accidents can be prevented.

In the above embodiment, the structure and construction method of the present invention was adopted for the flat outer wall surface, but the present invention is not limited to this, and this structure and construction method can be applied to the entrance corner and the exit corner. . That is, as shown in FIGS. 5 and 6, the covering sheet material 3 is adhered along the right-angled surface so as to cover the joint processing portion 2 of the ALC panels 1, 1 forming the right-angled portion, and then the same manner as the covering is performed. It suffices to fill the sealing material 4 between the sheet materials 3 and 3, and in this case as well, the same advantages as those of the above-described embodiment are obtained.

Further, as shown in FIG. 7, instead of the cover sheet material 3 of the above-mentioned embodiment, a sheet-like base material 30, an intermediate layer 32 mainly composed of an inorganic material, and a transparent or translucent waterproof property. It is also possible to use the covering sheet material 3 in which the surface layer 31 is laminated and integrated in the order, and the printing portion 31c is formed by printing on the back surface side of the surface layer 31 or the front surface side of the intermediate layer 32. . Needless to say, even when this covering sheet material 3 is used, the same effects as those of the above-mentioned embodiment are obtained.

Further, in the above-mentioned embodiment, the covering sheet material 3 is directly attached to the ALC panels 1, 1, but the present invention is not limited to this, and the ALC panels 1, 1 can be attached so as to eliminate a step on the front surface side. A base adjustment layer may be formed, and a cover sheet material may be attached to the base adjustment layer so as to cover portions of the ALC panels 1 and 1 corresponding to the joint treatment section 2. As the base adjustment layer, a layer mainly composed of an inorganic material such as cement can be used.

On the other hand, the projected corner portion may be configured as shown in FIG. In FIG. 7, reference numeral 6 is a metal square member, reference numeral 4'is a seal portion, and reference numeral 60 is a screw.
