Description

[Detailed Description of the Invention] The present invention relates to a water drainer, and particularly relates to an improved water drainer with improved drainage.

The conventional drain jointer has a Z-shaped cross section and the horizontal piece located between the upper and lower wall materials is flat, so it is installed at the joint of the upper and lower external wall materials so that the lower surface of the upper external wall material comes into contact with the horizontal piece. When the rainwater enters the back surface of the upper outer wall material, it is blocked and blocked by drainage along the draining material. This accumulated rainwater was causing the wood that formed the walls to rot. In order to prevent this, it is necessary to lift the upper outer wall material to ensure a clearance with the horizontal piece of the drain jointer, which is a complicated work when constructing the wall.

The present invention eliminates the above-mentioned drawbacks, and allows the upper exterior wall material to be brought into direct contact with the horizontal piece of the drain jointer during wall construction without inserting a gauge member between the outer wall material and the drain jointer, and has good drainage. We provide delicious Mizukiri Jiyoina.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, the drain jointer 1 of the present invention is a thin metal plate with a Z-shaped cross section, and although not shown, it is placed on the back surface of the upper exterior wall material 2a (on the right side in FIG. 1) through a waterproof sheet or the like. The upright piece 11 includes an upright piece 11, a hanging piece 12 that comes into contact with the surface of the lower external wall material 2b, and a horizontal piece 13 that is interposed between the opposing end surfaces of both of these external wall materials 2a and 2b. The upper end portion and the lower end portion of the hanging piece 12 are provided with U on the outer wall material side, respectively.
It has an upper water return piece 11a and a lower water return piece 12a which are bent into a letter shape.

The horizontal piece 13 has a slightly lower sloped surface on the surface side of the outer wall material, and a plurality of protrusions 13a extending almost the entire length along the width direction of the horizontal piece 13 protrude from the upper surface with the same width in the longitudinal direction. It is formed by extrusion from the bottom with a gap in between. However, protrusion 13
A valley groove 13b is formed between the grooves a, and a groove (not shown) is formed on the lower surface.

When constructing the wall, follow the above-mentioned procedure and install the lower external wall material 2b.
The horizontal piece 13 may be brought into contact with the upper surface of the horizontal piece 13, and the upper outer wall material 2a may be attached so as to be brought into contact with the upper surface of the horizontal piece 13.
With this, the upper outer wall material 2a is
3a, and a gap is secured between the groove 13b and the valley groove 13b. Therefore, even if rainwater enters the back surface of the upper outer wall material 2a, the rainwater flows along the front side of the upright piece 11 through the valley groove 13b and is discharged to the front side of the hanging piece 12. The protrusions 13a also help prevent rainwater from flowing sideways. Furthermore, when two jointers are connected to each other in the length direction, by overlapping the protrusions and grooves at the ends, it is possible to prevent rainwater from entering from this part, in addition to preventing the above-mentioned lateral flow. In addition, by overlapping the protrusions and grooves of the joiner, the joiner joint is stabilized, and there is also the effect that the overlapping margin at the joint end can be kept constant without having to measure it. This construction also applies to building foundations.

As described above, in the present invention, a plurality of protrusions are formed along the width direction on the upper surface of the horizontal piece of the drain jointer having a Z-shaped cross section, and have the same width in the longitudinal direction, and are spaced apart in the length direction of the jointer. The structure is easy to install, and rainwater that has entered the back side of the upper exterior wall material can easily flow out onto the exterior wall surface along the grooves between the ridges, preventing rainwater from entering the wall and rotting the wood. Things have disappeared. In addition, since there is no horizontal flow of rainwater on the horizontal pieces, when the joints are spliced together in the length direction, rainwater will not infiltrate from this part.
