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 water cutter jointer has a substantially Z-shaped cross section, and the horizontal piece located between the upper and lower wall materials is flat, so it is attached to the joint between the upper and lower exterior wall materials, and the lower surface of the upper exterior wall material comes into contact with the horizontal piece. During this time, rainwater that has entered the back surface of the upper outer wall material is blocked, and drainage along the drainage material is prevented. This accumulated rainwater was causing the wood of the walls to rot. That is, in cold winter regions, if the drainage of the intermediate drain is poor, water that collects between the wall material and the drain may freeze during the night, damaging the edges of the wall material. Additionally, if water is constantly accumulating, water absorption from the edges of the wall material will be promoted, leading to faster deterioration.

Furthermore, in the conventional structure of the intermediate drain jointer, water is sucked up to the back side by capillary action, so the water return must be made quite large. 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 substantially 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 that is connected to the lower outer wall material 2b, a hanging piece 12 that comes into contact with the surface of the lower outer wall material 2b, and a horizontal piece 13 that is interposed between the opposing end surfaces of both of these outer 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 inclined surface 13b on the outer wall material surface side.
A plurality of chevron-shaped protrusions 13a are formed on the upper surface thereof at intervals in the length direction, and the rising piece 11
and the hanging piece 12 are arranged side by side with an interval between them. The chevron-shaped protrusion 13a is formed by extrusion from the lower surface during molding of the drain jointer 1. The back surface of the chevron-shaped protrusion 13a becomes a chevron-shaped recess (not shown).

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.
Thereby, the upper outer wall material 2a is supported by the chevron-shaped protrusion 13a of the horizontal piece 13, and a gap is secured between it and the inclined surface 13b. Therefore, even if rainwater enters the back surface of the upper outer wall material 2a, the rainwater flows along the surface of the upright piece 11 and on the inclined surface 13b of the horizontal piece 13,
It is discharged onto the surface of the hanging piece 12. Chevron protrusion 13a
The shape is circular or close to it, and the bottom part is widened. Furthermore, when two jointers are joined in the length direction, by overlapping the chevron-shaped protrusions and the chevron-shaped recesses at the ends, it is possible to prevent rainwater from entering from these parts. Furthermore, by overlapping the protrusions and recesses of the joiner, the joiner joint is stabilized, and there is also the effect that the overlapping allowance at the joint end can be kept constant without measuring.

Instead of the chevron-shaped protrusion 13a, as shown in FIG.
c may be formed into a rib shape. According to this structure, when the horizontal joint portion of the wall material is placed on the protrusion 13c, the wall material itself becomes stable, and no step difference occurs between adjacent wall materials.

As described above, the present invention is a drain jointer having a substantially Z-shaped cross section, in which a plurality of chevron-shaped protrusions are arranged in parallel in the length direction on the upper surface of the horizontal piece whose outer wall material surface side has a slightly low slope. Since they are spaced apart from each other in the direction of the wall, and are arranged side by side with a space between them with respect to the upright piece and the hanging piece, it is easy to install the wall, and the back side of the upper exterior wall material can be easily installed. Since rainwater that has entered the wall can easily flow out onto the slope between the protrusions of the horizontal pieces to the front side of the outer wall, rainwater no longer enters the wall and rots the wood. Also, when the joints were layered together, rainwater no longer infiltrated from this area. Furthermore, since there is a gap between the upper exterior wall material and the horizontal piece of the drain jointer, dust will not accumulate in this area and capillary action will not occur, so the height of the water return can be lowered, contributing to material savings. It became.
