Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of coating a decorative sheet on the surface of a lightweight aerated concrete (hereinafter referred to as ALC) panel already installed on a structural frame. So, the old A
It is used when the surface of an LC panel is repaired or when a change in design is required even for a new ALC panel.

[Prior Art and Problems] Conventionally, as a method of covering the surface of an already installed ALC panel in a decorative manner, there is a method of spraying a spraying material such as synthetic resin or mortar.

However, this method has the disadvantage that the spraying material scatters during spraying, so masking of areas that should not be sprayed and dust countermeasures are required, and the spraying equipment generates noise. In addition, the spray material has the disadvantage that it is difficult to spray it evenly and tends to cause uneven coloring on the surface.

In addition, as a method to compensate for the drawbacks of the method using spray material,
- It is also practiced to attach a sheet to the surface of each ALC panel.

However, since multiple ALC panels are combined to form a wall surface, joints are formed between the panels, but if you want to leave these joints for aesthetic reasons or change the position of the joints, had the disadvantage that it could not be done simply by pasting the sheet because there would be no lines at the joints.

In addition, with the conventional method of attaching a sheet to each ALC panel, it was necessary to fill each joint with a sealant for waterproofing, but ALC panels are generally shortened in length relative to the structural frame. The drawback was that it required a lot of work because it was built and had many vertical joints.

The purpose of the present invention is to solve the above-mentioned problems and cover the surface of the ALC panel with a decorative sheet, which allows joints to be freely formed, changed, and erased on the surface of the ALC panel already installed on the structural frame. The goal is to provide a way to do so.

[Means for Solving the Problems] In order to achieve the above object, the method of covering the surface of an ALC panel with a decorative sheet according to claim 1 is a method of covering the surface of an ALC panel with a decorative sheet, which is formed by installing a plurality of ALC panels on a structural frame. On the wall surface, a corner that is flush with the surface of the panel is formed by attaching filling material to the chamfered or missing portion of the edge of the same panel that constitutes the joint, and the surface of the panel is used for decoration. At the same time as pasting the sheet, we took a method of wrapping the edge of the decorative sheet into the same corner and pasting it.

Furthermore, the method of covering the surface of an ALC panel with a decorative sheet according to claim 2 includes forming a new groove on the surface of a wall surface formed by installing a plurality of ALC panels on a structural frame; A decorative sheet was attached to the surface of the panel, and the edges of the decorative sheet were wrapped inside the outer corners of the groove to form joints. . Here, the construction joint part refers to a straight groove like a joint formed for decoration.

In addition, the method of covering the surface of an ALC panel with a decorative sheet according to claim 3 includes filling the joints between the panels with a filling material on a wall surface formed by installing a plurality of ALC panels on a structural frame. By doing so, we flattened the panel and attached a decorative sheet to the surface of the panel and the joint area.

Further, the method of covering the surface of an ALC panel with a decorative sheet according to claim 4 is such that in a wall surface formed by installing a plurality of ALC panels on a structural frame, the surface of the ALC panel is covered with a decorative sheet so as to cover the surface of the same plurality of panels. In addition to pasting the decorative sheet in the horizontal direction, we also took the method of pasting the decorative sheet by rolling it into the grooves at the joints between the panels.

[Operation: According to the method of claim 1, a new corner is formed with a filler material at the edge of the existing joint between the ALC panels, and then the edge of the decorative sheet is turned around the corner. Since it is closely adhered, it has the effect of making the ridgeline of the corner clearly visible even after it is covered with the decorative sheet.

According to the method of claim 2, a new groove is formed on the surface of the ALC panel, and the decorative sheet is rolled and pasted inside the outer corner of the groove, so that a new joint is formed. Moreover, it has the effect of clarifying the ridge lines of the corners of the joints.

According to the method of claim 3, the existing joints are filled with the filling material, flattened, and then covered with the decorative sheet, so that the joints become invisible in appearance after being covered with the decorative sheet. It has an effect.

According to the method of claim 4, the decorative sheet is a plurality of AL
In addition to covering the C panel at the same time, the decorative sheet also serves as a seal for the vertical joints.
