JPH07139120A - Crack preventing method for finishing material for thick smooth finishing for outermost layer of joint for external wall panel - Google Patents

Abstract

PURPOSE:To prevent cracks from occurring to finishing materials on the outermost layer of joints, and to keep beautiful exterior for a long period of time by a method wherein a decking for smooth finishing is made over the outermost layer of the joint after the joint is filled with a dent in a specified depth provided, and decorative caulking is applied to the dent. CONSTITUTION:Filling 3 is applied to the outermost layer of a joint of external wall panels utilizing ALC boards 1, and the surface of the external wall is made to be a smooth surface 5. The outermost layer of the joint, with filling 3 applied thereto, is then cured with a joint strip 4, and smooth finishing is made with cement filler in the thickness of the joint strip 4. The joint strip 4 is removed and a dent in a C shape 6 is formed for applying finishing material thereto. After coloring finishing material 7 is applied to the surface of the panel, decorative caulking 8 is applied to the dent. Thereby, cracks can be prevented from occurring to the finishing material on the outermost layer of the joint with movement absorbed by the decorative caulking even in the case where the joint between the ALC boards moves because of vibration applied to a building.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of applying cosmetic caulking so that a finishing material for an ALC plate joint is not cracked even when a building body moves.

[0002]

2. Description of the Related Art Conventionally, as a finish of an outer wall panel using an ALC plate, as shown in FIG. 1, direct spraying of an uneven pattern (9) or porcelain tile application is mainly performed on a waterproof caulking (2). .

[0003]

[Problems to be solved by the invention] However, since the spray material or the porcelain tile cannot adhere to the movement of the ALC plate, many cracks occur on the surface, which impairs the aesthetics and costs a lot of repair work. The building was left as it was. The present invention is intended to develop a smooth finishing method which is free from cracks and has a high-class feeling of the finishing material for the surface layer portion, excluding its drawbacks.

[0004]

[Means for solving the problem] After backfilling the joint portion of the ALC seam in the seam layer portion of the outer wall panel using the ALC plate, a step (6) is formed in a U-shape so that makeup caulking can be performed, and a recess finishing material Make-up caulking (8)
This is a method to prevent cracking of the finish material of the outer layer of the outer wall panel by applying a thick and smooth finish.

[0005]

[Action]

1. ALC seam filling (3) is performed to make the outer wall surface smooth (5). 2. The joint layer (4) is used to cure the joint layer of the ALC plate with joint filler (4), and the cement filler is used to finish the joint to a smooth thickness. 3. Next, the joint bar is removed and the lower map 3 with steps is made. 4. Next, after the surface is colored and finished (7), makeup caulking (8) is applied to the joint recess. Since this plan has the structure as described above, even if the LLC plate moves due to the movement of the building, cracks will not occur on the surface of the finishing material.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. After backfilling the joints of the ALC seams in the outer layer of the outer wall panel using the ALC plate, make a step (6) in the U-shape so that you can hit the makeup caulk, and make a makeup caulk (8) in the recess finishing material part Since this is a method for preventing the cracking of the finish material for the outer layer of the outer wall panel by thick and smooth finish, even if the building moves due to the passage of a large vehicle, etc. The material does not crack.

[0007]

EFFECTS OF THE INVENTION Even if the edge of the joint of the ALC plate and the finishing material is cut off, and even if the body moves, the cosmetic caulking absorbs the movement, so that the surface of the finishing material does not crack. Moreover, with this method, a smooth finish with a high-class feeling can be applied on site and the cost is low. Also, with the conventional construction method, the cracking of the caulking part would occur within a few months at the earliest, which impaired the aesthetics of the building and incurred high repair costs. It is economical because it keeps the beauty of time. In addition, since it prevents cracks at the cosmetic caulking joints, it has the effect of preventing water from entering the interior and extending the life of the building.

Claims (1)

[Claims] 1. Backfilling of a joint portion of an ALC seam in a seam layer portion of an outer wall panel using an ALC plate (3).
After that, make a step (6) on the U-shape so that you can hit the cosmetic caulking (8) and hit the cosmetic caulking on the recessed finishing material part.
