Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a dry type composed of one kind of an outer wall of a building, a structure, a house, etc., particularly a metal siding material containing a core material, a ceramic siding material, an ALC plate, etc. The present invention relates to a waterproof vertical joint structure of butt vertical joints when an outer wall is formed by horizontally installing an outer wall material on a body composed of main columns and studs.

[Conventional technology]

Generally, the waterproof structure in the vertical joint when the outer wall is constructed by using the horizontal siding material is the structure using the H joiner as shown in Japanese Utility Model Laid-Open No. 56-102308, or the actual open type Sho 60-8.
A structure using a T-joiner as shown in Japanese Patent No. 307, or a structure in which a joint material is simply filled in a joint gap, or a cover member is attached to a joint portion using a mounting bracket as shown in Japanese Patent Laid-Open No. 59-217866. The structure and the like are known.

[Problems to be Solved by the Invention] However, the vertical joint structures shown in the above three publications not only impair the aesthetics because the horizontal joints divide the entire outer wall while running, but also the outer wall material, for example, The metal siding material with gypsum board as the core material has the drawback that rainwater from the decorative surface intrudes into the core material from the mouth of the horizontal joint by capillary action due to wind and rain, melting the gypsum and corroding the metal plate. . Further, when the dry type outer wall material is Nanjing siding (tiered), rainwater leaks extremely between the back surface of the metal plate and the core material, and the T-joiner surface can be seen from the side, resulting in a further deterioration in aesthetic appearance. Further, in the structure in which the joint material is filled, the joint material and the outer wall of the outer wall material have a drawback that they are difficult to adhere to each other particularly in the outer wall material having the plastic foam as a core material, the waterproof property is poor, and the base is corroded. Furthermore, in ceramic siding, it is difficult to reliably fill joints with narrow joints of 1 to 2 mm, and in the case of hollow cavities, only the surface is flush with the structure, resulting in poor weather resistance and rainwater. Had the disadvantage of getting inside.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention uses, as the exterior material, the siding material of the composite board structure in which the cross section of the mouth and the majority of the decorative surface in the vicinity of the mouth are covered with a waterproof coating material with an adhesive on the body. Symmetrically with respect to the same vertical line of, and fixed with a narrow gap to form a plurality of vertical joints corresponding to the wood mouth hanging from the girder to the base, the vertical joints on the decorative surface All vertical joints are covered with joint coverings that are about twice as wide as the exposed waterproof coverings, and joint coverings wider than the above joint coverings are applied to each siding material from the base to the girder. This is to propose a waterproof vertical joint structure of a wall using a dry type outer wall material, which is characterized in that a vertical joint is formed by facing toward.

[Action]

Uses a dry outer wall material that has a beautiful wall appearance and prevents rainwater from entering the interior, as well as preventing rust at the mouth of the metal siding material, preventing cracks due to freezing of the ceramic siding material, and eliminating corrosion of the body. It will be a waterproof vertical joint structure of the existing wall.
