Description

[Detailed Description of the Invention] This invention relates to a draining material for an exterior wall that is attached to the lower end of a ventilation wall that takes outside air into the wall and prevents condensation.

Some of the rainwater that flows along the outer surface of the wall drips from the bottom of the wall and falls to the ground, but some of the rainwater falls from the bottom of the wall, especially during wind and rain. It turns to the bottom and enters the wall,
This may accelerate the deterioration of buildings. Conventionally, drainage materials were attached to the lower end of the wall to prevent rainwater from entering the wall.

Incidentally, recently, insulation materials have been filled into the walls of buildings from the perspective of energy conservation, but when there is a large temperature difference between indoor and outdoor temperatures, such as in summer or winter, the amount of heat insulating material contained in the air increases. There was a risk that the moisture in the wall would condense inside the wall, causing corrosion from inside the wall.

Therefore, conventionally, for example, as shown in Figure 1,
A wall 1 in which an air flow path A is provided by cutting out a part of the horizontal stile 1a in the vertical direction is installed on the architrave 3 placed at the top of the foundation 2, and the lower end surface of the wall 1 and As shown by the arrow, outside air is introduced into the wall 1 through the flow path A from the gap created between the top of the foundation 2 and the top of the foundation 2, and the introduced air is released from the attic or eaves to the outside. Natural ventilation was provided.

However, in the case of the configuration shown in FIG. 1, the rainwater flowing down the outer surface of the wall 1 is diverted to the lower end surface of the wall 1 by the drainage material 4 attached to the lower end of the wall 1. Even if this is not the case, water that has fallen to the ground and bounced back may accumulate between the bottom end of the wall 1 and the top of the foundation 2, causing corrosion from the bottom end of the wall 1. It was hot. Furthermore, if rainwater or the like accumulates between the lower end surface of the wall 1 and the top end of the foundation 2, highly humid air will be introduced into the wall 1 through the flow path A, resulting in a state where dew condensation is likely to occur. There was a problem with becoming.

This idea solves the above problem by providing an auxiliary piece from the upright part to the bent piece, and alternately arranging ventilation holes in this auxiliary piece and intake holes in the upright part. The object of the present invention is to provide a drainage material for exterior walls that can provide ventilation and prevent wall corrosion.

This invention will be explained in detail below based on the drawings.

2 to 5 show an embodiment of this invention. For example, an exterior wall draining material 10 made by extrusion of aluminum has a raised part 11 and a raised part 11 as shown in FIG. A guide portion 12 is provided approximately at the center of the rising portion 11 and protrudes outward with a water gradient, and the rising portion 1 is located at the tip of this guide portion 12.
1, an auxiliary piece 14 connected to the bending piece 13 with a water slope extending from the lower end of the rising part 11, and a lower end of the rising part 11. Water receiving piece 15 protruding almost vertically inward
It is made up of. And this exterior wall drainage material 10
, the rising part 11, the guide part 12 and the bending piece 1 are included.
3 and the auxiliary piece 14 form a hollow part B.

The rising portion 11 has a rib 11 at the upper end portion on the outer side.
A is provided, and furthermore, a V-shaped groove 11b is formed on the outer side between the upper end and the guide part 12 to serve as a guide for nailing for installation, and a V-shaped groove 11b is formed between the guide part 12 and the auxiliary piece 14. The structure is such that horizontally elongated intake holes 11c are formed at intervals of, for example, about 230 mm. The lower end of the air intake hole 11c is configured to be flush with the upper surface of the water receiving piece 15 and flush with the upper end of the auxiliary piece 14 provided with a water gradient.

Further, the guide portion 12 has a convex portion 12a which serves as a receiving portion and a ruler when an outer wall layer is formed approximately in the center of the upper surface thereof. The bent piece 13 has a rib 13a on its inner side and at its lower end.

Further, the auxiliary piece 14 includes, for example, a slope portion 14 which is connected to the lower end portion of the upright portion 11 and has a water slope.
a, and a bent piece 13 from the lower end of this slope portion 14a.
It consists of a horizontal part 14b that is horizontally connected to the inner side. Ventilation holes 14c are provided in this horizontal portion 14b at intervals of, for example, about 230 mm. The ventilation holes 14c are provided so as to alternate with the intake holes 11c, and are located approximately in the middle of the intake holes 11c.

In addition, the ventilation hole 14c is provided in the horizontal portion 14b that is connected horizontally from the lower end of the sloped portion 14a of the auxiliary piece 14 to the inner side of the bent piece 13. This means that it was installed at the lowest position of No. 14.

On the other hand, the exterior wall drainage material 1 configured as described above
0 is attached to the wall 16 as shown in FIGS. 3-4. The wall body 16 is made by, for example, assembling core materials vertically and horizontally with holes that allow air to circulate in the vertical direction, and assembling frames 16a around the four peripheries.
It is constructed by filling the indoor side of the interior with a heat insulating material 16f and pasting face materials 16b on both sides of the heat insulating material 16f. The stile 16a at the lower end of the wall body 16 has a plurality of notches 16c each having a rectangular cross section on its outer side and in the vertical direction.
are formed opposite the intake holes 11c formed in the rising portion 11 at the same interval. This notch 16
The width of c is set to be approximately the same as the width of the intake hole 11c of the upright part 11 of the outer wall drainage material 10, and the depth thereof is set to be shallower than the width of the water receiving member 15. Further, at the lower part of the outer side of the wall body 16, there is a rising part 1 from the lower end surface of the stile 16a.
A mounting portion 16d is provided by cutting off the lower end of the face material 16b by a height of 1. A waterproof coating 16e is coated on the surface of the outer side panel member 16b and the surface of the mounting portion 16d.

Therefore, in the mounting portion 16d of the wall 16,
The upright part 11 of the exterior wall draining material 10 is attached with a nail 20 or the like with its inner side in contact with the raised part 11, and the upper surface of the water receiving piece 15 is provided in contact with the lower end surface of the frame 16a. There is. That is, as shown by the arrows in FIGS. 2 and 4, the outside air flows from the ventilation hole 14c of the auxiliary piece 14, through the hollow part B, through the intake hole 11c of the upright part 11, and into the notch 16c of the stile 16a. Then, it rises and is introduced into the wall 16. In this case, even if rainwater or the like rebounds and enters the hollow part B from the ventilation hole 14c, the ventilation hole 14c and the intake hole 11c are staggered, so that it can pass through the hole in the frame 16a through the intake hole 11c. It does not penetrate into the recessed part 16c, so the lower end of the wall 16 is not rotted.

In addition, rainwater that has entered the hollow part B flows down from the slope part 14a of the auxiliary piece 14 and quickly flows to the ventilation hole 1.
It is discharged from 4c. In other words, rainwater flows into the hollow part B.
Therefore, there is no need to introduce high humidity air into the wall 16 as in the conventional case, and the inside of the wall 16 can be naturally ventilated with air always having the same humidity as the outside air. Condensation inside the wall 16 can be prevented. Of course, the air introduced into the inside of the wall 16 is
c, and passes through a hole in the core material inside the wall and is emitted to the outside from, for example, the attic or eaves side.

Further, the water receiving piece 15 has the recessed portion 16c.
Since the width is wider than the depth of the notch 16c.
The opening at the bottom of the can be closed. In addition, even if dew condensation should occur inside the wall 16, the water droplets will pass through the notch 16c and be received by the water receiving piece 15, and then flow from the intake hole 11c through the slope portion 14a and the ventilation hole 14c. It is discharged to the outside. In this case, the upper surface of the water receiving piece 15 and the air intake hole 11 of the upright part 11
Since the lower end surface of the auxiliary piece 14 is flush with the lower end surface of c, and the sloped part 14a of the auxiliary piece 14 is formed from this lower end surface, the condensed water drops are transferred to the water receiving piece 1 of the recessed part 16c.
5, the intake hole 11c, the slope part 14a,
It is discharged to the outside through the horizontal portion 14b and the ventilation hole 14c. Therefore, water droplets and the like do not accumulate in the lower part of the recessed portion 16, so that the wall body 16 is not corroded.

As a matter of course, the outer surface of the wall 16 is filled with caulking material 17a on the upright portion 11, and the convex portion 12a of the guide portion 12, for example, is filled with caulking material 17a.
The outer wall layer 17 is provided using a ruler. Further, this wall body 16 is installed on an architrave 19 at the top of the foundation 18.

On the other hand, when building a dirt floor or basement, the foundation 1
In order to prevent rainwater from entering inside the wall 16, caulking material or the like must be filled between the lower end of the wall 16 and the top end of the foundation 18 to make it watertight. By the way, in the case of this exterior wall drainage material 10, as shown in FIG. If the caulking material 21 is heaped up on the outside of the ring 19 and the wall 16 is placed on top of it by crushing the caulking material 21, there is no risk of blocking the air flow path, and this can be done efficiently and efficiently. The caulking material 21 can be filled in a watertight manner.

In addition, in the above embodiment, the auxiliary piece 14 is
a and a horizontal portion 14b, but the horizontal portion 14b may not be provided and it may be configured only from a slope portion. In this case, the ventilation hole 14c is placed at the lowest position of the auxiliary piece 14, that is, the auxiliary piece 14 is placed at the lowest position of the bent piece 14.
If it is provided near the position where it comes into contact with the water, drainage can be improved.

As explained above, this invention has a guide part protruding from the upright part, a bent piece hanging down from this guide part,
In addition, an auxiliary piece is provided continuously from the upright part to the bent piece,
Since intake holes and ventilation holes are provided alternately in the upright part and the auxiliary piece, if the exterior wall draining material configured in this way is attached to the wall,
Even if rainwater enters through the ventilation hole, it will not reach the intake hole and will not corrode the lower end of the wall. Moreover, since the auxiliary piece is provided with a water gradient, even if rainwater enters the hollow part, it can be quickly discharged from the ventilation hole due to its water guiding action. Air with the same humidity as the outside air is always introduced into the wall to provide natural ventilation and prevent condensation.
Furthermore, the lower end of the intake hole is formed flush with the upper surface of the water receiving piece and the upper end of the auxiliary piece provided with the water gradient, and the lower end of the wall and the foundation are formed on the upright part. A protruding water receptacle is inserted between the walls, so even if dew condenses inside the wall, the dripping water will be smoothly guided and discharged and will not accumulate, blocking the lower end of the notch in the wall. At the same time, even if rainwater splashes back from below, it will not enter the wall and corrosion can be prevented.
