DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining material which is attached to the lower end of an outer wall of a building to apply ventilation inside the wall of the outer wall and below the floor. The present invention relates to a member that also functions.

[0002]

2. Description of the Related Art A drainer is attached to a lower end of an outer wall of a building to drop water flowing down from the outer wall without approaching the base. Further, in order to improve the durability of the structural frame in a house, it is required to adopt a ventilation structure method in which a ventilation layer is provided inside the outer wall. Therefore, it is necessary to rationally put the drainage portion and the ventilation portion between the foundation and the outer wall.

Conventionally, when a dry outer wall material such as ceramic siding is employed, a draining material 1 as shown in FIGS.
Is fastened to the structural body (base) 21, a rim 25 is provided, and the outer wall material 22 is extended to the rim so as to form a gap of about 10 mm from the draining portion 3 of the draining material 1, thereby forming a ventilation layer in the wall. Had a vent to it.

On the other hand, when a wet outer wall such as mortar is used, the drainer 1 is fastened to a structural frame (base) 21 as shown in FIG. In order to form a gap between the drainer 1 and the outer wall mortar layer 30, a parting material 41 is provided at the lower end of the lath 32 to position the lower end of the mortar layer 30, and The air gap formed between the draining part 3 was used as a vent.

[0005]

However, since the above-described vent of the conventional ventilating layer in the wall is directly in contact with the outside, the structural frame (base) is required in consideration of intrusion of rainwater into the wall by wind and rain. Mounting part 2 for mounting drainer 1 to 21
Had to be enlarged. For this reason, the mounting portion 2 of the draining material interferes with the outer wall base material (hull edge) 25, causing irregularities in the outer wall material 22 and possibly causing cracks or the like when the outer wall material is constructed.

In addition, in order to provide a ventilation hole for the ventilation layer in the wall, an outer wall material must be constructed so as to open a gap between the outer wall material 22 and the drainage portion 3 of the drainage material. The construction was complicated. In addition, when a wet type outer wall is adopted, a parting material 41 is provided at the lower end of the outer wall.
However, there is a problem that the construction becomes complicated and the cost increases.

[0007] In view of the above, the present invention can be carried out without giving the outer wall material unevenness, and can eliminate the trouble of dimensioning the overhanging position of the outer wall material and parts such as a parting material, and can be easily constructed. Is provided.

[0008]

According to the present invention, there is provided a drainage material which extends vertically along an outer wall, an outer wall supporting portion extending forward from a lower end of the mounting portion, and a lower portion extending from a vicinity of a tip of the outer wall supporting portion. A water return portion to be formed, a drain portion extending obliquely downward from the lower end of the water return portion, a vertical portion extending downward from the tip of the drain portion, and a bottom portion extending in the base direction from near the lower end of the vertical portion. A vent hole is provided in the outer wall support portion and the bottom portion. By adopting such a configuration, the outside air that has entered through the ventilation hole formed in the bottom surface portion flows through the wall through the ventilation hole for the wall formed in the outer wall holding portion. Also, it acts to flow under the floor through a vent provided between the foundation and the base.

In addition, a turn-back portion is provided at a base-side end portion of the bottom surface of the drainer. By adopting such a configuration, when water intruding from the opening or the gap between the outer walls or water droplets generated in the wall due to dew drops to the bottom from the ventilation hole for the inside of the wall, the bottom of the bottom is further damaged by wind and rain. Even when water enters through the vent hole, it acts to prevent the water from flowing down the floor.

[0010] The outer wall supporting portion serves as a starter serving as a load-carrying rule when the dry outer wall material is constructed, and functions as a start portion of the outer wall material, so that complicated positioning work and cost of a parting material are omitted.

The material is not limited to aluminum, but may be a metal material such as stainless steel or a steel plate or a plastic material such as PVC, and the processing method is not limited to extrusion but may be bending or the like.

The mounting portion 2 is composed of a vertical rising surface for fastening to the structural body (base) 21 with a nail or a screw. Horizontal kerf 1 having a V-shaped cross section that can penetrate
1 is provided. Further, instead of the kerf 11, a plurality of holes for inserting fixing members may be formed. The outer wall support portion 3 is a substantially horizontal flat portion extending forward from the lower edge of the mounting portion 2, and is slightly inclined forward to form a drainage gradient to facilitate drainage from the inside of the wall. The length of extension of the outer wall support portion 3 in the inward and outward directions is slightly larger than the thickness of the rim of the wall base. The outer wall supporting portion 3 serves as a reference for overhanging the outer wall material when a dry method is employed.

The water return portion 4 is a flat or curved portion extending downward from the vicinity of the tip of the outer wall support portion 3.
In addition to the tip end, the water that has fallen into the drainer 5 is prevented from flowing toward the outer wall due to wind. The draining part 5 is a flat part extending obliquely downward and forward from the lower end of the water return part 4 and guides water flowing down the outer wall so as not to approach the base. The vertical portion 6 is a flat portion extending downward from the tip of the draining portion 5. The bottom portion 7 is a flat portion extending in the base direction from near the lower end of the vertical portion, receives water dropped from the inside of the wall, guides the water to the outside, and prevents the base portion from getting wet. The lower end of the vertical portion 6 slightly projects beyond the bottom portion 7 to prevent water flowing from the draining portion 5 from traveling along the bottom portion 7 and reaching the foundation. A turn-back portion 8 is raised at the base-side end portion of the bottom portion 7 (substantially immediately below the mounting portion 2) to prevent the water received at the bottom portion 7 and the rainwater that has entered due to wind and rain from penetrating below the floor. .

The outer wall support 3 has a circular air hole 9 having a diameter of about 13 mm for introducing outside air between the outer wall and the structural body and discharging water entering through an opening or the like to the bottom.
Are formed in the longitudinal direction. A plurality of circular air holes 10 having a diameter of about 13 mm are formed in the longitudinal direction in the vicinity of the tip of the bottom portion 7 to introduce outside air into the wall and below the floor and to discharge the water dropped on the bottom portion to the outside. ing. The ventilation hole 9 for the inside of the wall formed in the outer wall supporting portion and the ventilation hole 10 formed in the bottom portion serve to discharge water droplets inside the wall to the outside and to take in outside air for ventilation inside the wall and under the floor. However, the shape and dimensions are not limited to the above, and may be elliptical, rectangular, etc., and the size has an opening enough to allow outside air to pass through, It is preferable that the size is such that insects and the like do not enter.

The drainage material of this embodiment can be used regardless of whether the outer wall is of a dry construction method or a wet construction method. FIG. 3 shows an example of construction when the dry method is employed.
The base 21 is placed on the cloth foundation 20 via the ventilation packing 23.
Is installed. When constructing the outer wall, first, the bottom portion 7 of the draining material is placed on the cloth foundation 20, and the cutting groove 11 of the mounting portion 2 is penetrated with a nail or a screw to fix the draining material 1 to the structural frame (base) 21. Then, a moisture-permeable waterproof paper 26 is attached so as to cover the mounting portion 2. Further, the rim 25 is fixed to the structural skeleton 21 at predetermined intervals in the vertical direction, the lower end of the ceramic outer wall material 22 is placed on the outer wall support portion of the drainer 1, and nails or screws or Fasten with metal fittings. A decorative mortar layer 24 is applied to the outside of the fabric base 20.

FIG. 4 shows an embodiment in which the drainer 1 of the present invention is employed in a wet method. As with the dry method,
After the drainer 1 is fastened to the structural body (base) 21 with nails or screws, the moisture-permeable waterproof paper 2
Paste 6. Thereafter, the body edge 25 is fastened to the structural skeleton 21 at predetermined intervals in the vertical direction, and the wood edge 32 is attached to the body edge 25.
The mortar layer 30 is formed by providing the waterproof paper 33 and the lath net 31 in this order. In this case, since the drainer 5 functions as a starting portion of the mortar layer 30, a parting material is not required.

In FIG. 3 or FIG. 4, the outside air entering through the ventilation hole 10 flows under the floor through the ventilation hole formed by the base 21 and the ventilation packing 23 between the foundation 20 as shown by the arrow, so that it flows under the floor. The ventilation of
Since the water flows from the ventilation hole 9 for the inside of the wall to the inside of the outer wall and flows out from the vent of the eaves or the ridge, there is no possibility that the inside of the outer wall becomes high humidity and dew condensation occurs.

Even when rainwater or the like enters the back side of the outer wall from the opening or the gap of the outer wall material, or when dew condensation water is generated, the water is guided to the outside according to the inclination of the outer wall support 3. Then, it falls from the ventilation hole 9 for the inside of the wall to the bottom portion 7 and is discharged out of the ventilation hole 10. On the other hand, since the folded portion 8 is provided on the base side of the bottom portion 7, even when rainwater or the like flows down from the ventilation hole 10, the infiltration of the rainwater is suppressed by the folded portion 8, and it is possible to prevent the rainwater from entering under the floor. Since the bottom part 7 covers the foundation 20, there is no need to wet the foundation. Also,
Since the water return portion 4 is provided, rainwater does not flow directly into the wall from the drain portion 5 due to wind and rain.

Since the water return portion 4 is provided in the water drain portion 5 and the outside air intake for ventilating the inside of the outer wall is not in direct contact with the outside, rainwater from the water drain portion 5 to the inside of the outer wall due to wind and rain is provided. Can be prevented, and the rising dimension of the mounting portion 2 can be reduced. As a result, the mounting portion 2 and the rim 25 are less likely to interfere with each other and the outer wall is less likely to be uneven.

The draining material of the present invention has the most excellent function when it is used in a base part having a structure in which a ventilation layer is provided between an outer wall finishing material and a frame, and ventilation is provided under the floor using a cat base. However, it can be installed even when only one of the ventilation wall or cat base is used.
It can be used for various construction methods such as steel frame construction.

Also, since a multifunctional outer wall support is provided,
The present invention can be applied to any of a dry method for finishing outer wall materials such as ceramic siding, ALC, metal siding, and resin siding, and a wet method such as mortar finishing.

The present invention is not limited to the above embodiment, but can be freely modified and implemented within the scope of the claims. In particular, the material and shape of the drainer, the number of vents,
The size and shape are free.

[0025]

As described above, the drainer according to the present invention comprises a mounting portion, an outer wall supporting portion extending forward from the mounting portion, a water return portion extending downward from the vicinity of the end of the outer wall supporting portion, and an oblique front portion from the water returning portion. Draining portion extending in the direction, a vertical portion extending downward from the draining portion, and a bottom portion extending in the base direction from the vertical portion, the outer wall support portion and the bottom portion are provided with ventilation holes. Thus, the inflow of the outside air that ventilates the inside of the outer wall does not directly contact the outside world, so that the infiltration of rainwater from the drain portion is prevented. For this reason, the rising dimension of the mounting portion can be reduced, and the draining material and the body edge do not interfere with each other, so that unevenness with respect to the outer wall material does not occur. Therefore, cracks or the like that occur when the outer wall material is constructed can be suppressed.

When the dry method is adopted, the lower end of the outer wall material is placed on the outer wall supporting portion, which can be used as a reference for the start of sticking, and there is no need to form a gap between the drainer and the outer wall material. The time and effort for positioning and dimensioning for pasting can be reduced, and the workability is excellent.

When the wet method is employed, the draining portion functions as an outer wall starting portion, so that a parting material and the like can be omitted, and the cost can be reduced.

Also, since there is a folded portion on the base side of the bottom surface, water that has entered the backside of the outer wall from the opening of the building or the gap between the outer walls or water generated by condensation falls from the ventilation hole for the inside of the wall to the bottom portion. In this case, even if rainwater infiltrates through the ventilation hole due to wind and rain, water does not flow under the floor. In addition, since the draining material has a structure that covers the foundation, the foundation does not wet. For this reason, the life of the skeleton and outer wall is extended,
Overall, the durability of the house is improved.

Further, since the plurality of ventilation holes provided on the bottom surface are small, rats and insects are unlikely to enter the inside of the outer wall or below the floor.

The drainage material of the present invention can be used for dry and wet ventilation methods, and can freely ventilate the outside air both inside the outer wall and under the floor.
