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-.
A structure using a T-joiner as shown in Japanese Patent No. 8307, 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, a metal siding material having a gypsum board as a core material. In this case, rainwater from the decorative surface is incompletely waterproof due to wind and rain at the joints of the so-called outer wall material, so that it penetrates from the joints to the wood mouth and core material by a capillary phenomenon, dissolves gypsum, or metal plates. There was a drawback that it corroded. In addition, when the dry type outer wall material is Nanjing siding (tiered), rainwater is extremely leaked 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 filled with the joint material, the joint material and the outer surface of the outer wall material are difficult to adhere to, especially with the outer wall material having the plastic foam as the core material, and the waterproof property is poor.
There was a drawback that the base was 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 has a vertical joint having a shape similar to that of the mouth of each outer wall material and having a V-shaped cross section having a height not protruding from the decorative surface. Is repeatedly installed from the bottom to the eaves, corresponding to the mouth, and the upper end of the lower gutter is positioned below the lower end of the upper gutter to form a stepped drainage channel. At the same time, a coating layer and caulking material are added to the vertical joints so that the troughs of the gutter function as drainage channels, and the openings are filled so as to close the openings. It is possible to form vertical joints without leakage, corrosion of the base material, surface material, core material,
We propose a waterproof vertical joint structure for walls using a dry type outer wall material that is waterproof against deterioration and has improved weather resistance.

[Operation] The gutter described above functions as a running channel for rainwater that has entered from the vertical joints, quickly discharges rainwater toward the base, and does not project from the surface of the outer wall material. Since the through appearance can be formed and only the opening of the gutter can be filled with the paint layer and the caulking material, the waterproofness and weather resistance of the vertical joint can be improved.

〔The invention's effect〕

As described above, according to the vertical joint structure of the present invention, the vertical joint, which hinders the appearance of the horizontal lining, becomes inconspicuous as a whole wall and can be formed into a beautiful outer wall. Rainwater that leaks from the grain openings in the horizontal and vertical joints of the board to the inside of the board, the ground, etc. is drained to the outside without infiltrating the inside of the decorative surface of each board to the inside by at least a double waterproof layer, and the rainwater to the back of the board and the ground Waterproof leaks and eliminate corrosion caused by water leaks. Construction is easy and the cost is almost the same as before.
The drainage channels are arranged in a staircase pattern from the girder to the base in correspondence with each board, and the inclined part of the upper gutter body does not contact the upper end part of the gutter body of the lower board. Capillarity can also be eliminated by leakage. The gutter is placed in the space between the wood openings of the board so that the elasticity of the gutter itself does not create a gap between the wood opening and the side wall of the gutter, and the rainwater from entering the inside of the decorative surface of the board is waterproofed. It is led to the valley part of the to prevent rainwater from leaking to the base and prevent corrosion of the core material and skeleton. Leakage of rainwater from the horizontal joints to the vertical joints is also characterized by being drained to the outside through the troughs of the gutter and being able to be waterproofed from entering the inside.
