DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described with reference to the drawings shown as embodiments. In this embodiment, as shown in FIGS. 1 and 2, a large number of ALC panels 1 are arranged to form the outer wall surface of a building, and the surface finishing structure of the present invention is adopted. [Overall structure] As shown in FIG. 1 and FIG.
A large number of panels 1 are arranged and fixed, and a covering sheet material 3 is adhered to the ALC panel 1 with an adhesive 5 so as to cover the joint treatment portion 2 of the adjacent ALC panels 1 and 1. The sealing material 4 is filled in a small gap between the edges of the materials 3 and 3. In this embodiment, ALC panels 1 having a width of 600 mm are vertically arranged as shown in FIG. [About Covering Sheet Material 2] As shown in FIGS. 3 and 4, the covering sheet material 2 includes a sheet-shaped base material 30 and a waterproof coating layer 31.
The sheet-shaped base material 30 is manufactured by spraying or applying a waterproof coating on the sheet-shaped base material 30. Here, the cover sheet material 2 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 (hereinafter referred to as the site).

As the sheet base material 30, a woven fabric formed by weaving glass fibers is used, which secures the strength of the sheet itself and prevents the waterproof paint layer 31 from peeling off from the sheet-like base material 30. are doing. The sheet base material 30 is not limited to a woven glass fiber, but a woven resin fiber may be adopted, or a woven fiber of these fibers may be used. Further, it may be a resin sheet that is deformable and has a roughened surface.

The waterproof paint layer 31 is made of an acrylic resin in this embodiment. However, this is not limited to the acrylic resin, and other types of resins can be adopted as long as they have waterproofness. Further, considering that when the covering sheet 3 is used in the entering corner or the exiting corner, the waterproof coating layer 31 has a certain degree of flexibility in a dry state, considering that the covering sheet 3 is adhered following these. It is preferable.

Here, the joint treatment portion 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, and an ALC panel is placed on the sealing material 20. The cement material 21 is filled up to a position flush with the surface of 1. [Regarding Adhesive 5] The adhesive 5 preferably has waterproofness, and an epoxy type is used, but other types can also be used. [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. In this embodiment, the sealing material 4 has a heat insulating property and a waterproof property. Modified silicon type is used. In this embodiment, the width for filling the sealing material 4 is 6 mm and the thickness is 4 mm.

Next, the order of construction for completing the surface finishing structure of the ALC outer wall surface of this embodiment will be described. It is assumed that the joint processing 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 constitute the outer wall, and then the adhesive sheet material 3 is sequentially attached. At this time, as shown in FIGS. 1 and 2, the joint processing section 2 is covered with the central portion of the cover sheet material 3.

There are no cracks on the wall surface. Therefore, it looks good and rainwater does not enter the inside where the steel aggregate exists. The cover sheet material 3 has elasticity and the sealing material 4
Has excellent elasticity, so even if the ALC panels 1 and 1 are displaced from each other, the sealing material 4 is not broken or the cover sheet material 3 is peeled off. Can be secured. . It has a luxurious finish like a panel stuck on the entire wall. . Basically, since the cover sheet material 3 is simply attached, 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 the generation of odors (this situation may occur due to the notification of the Ministry of International Trade and Industry) and paints may adhere to buildings, vehicles, etc. around the site. No problems such as these occur, and there are almost no remaining cans and waste materials. . Unlike the tiles and the like, the cover sheet material 3 is light, so there is little risk of falling during construction, and accidents can be prevented. Although the structure and construction method of the present invention is adopted for the planar outer wall surface in the above-mentioned embodiment, the present invention is not limited to this, and this structure and construction method can be adopted for the entry corner and the exit corner. That is, as shown in FIG. 6 and FIG. 7, 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 covering sheet is similarly formed. It is sufficient to fill the sealing material 4 between the materials 3 and 3,
Also in this case, the same advantages as those of the above-mentioned embodiment are obtained.
