Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a draining material used for a building of a construction method in which a foundation packing is sandwiched between a cloth foundation and a base at an appropriate interval and ventilation is performed under the floor from a gap between the cloth foundation and the foundation.
[0002]
[Prior art]
When such an underfloor ventilation method is employed, it is necessary to prevent the intrusion of the bag from the gap between the fabric foundation and the base. For this reason, conventionally, a fender is continuously provided in the horizontal direction from the lower end of the front hanging portion of the draining material, and only air is passed through a large number of holes formed on the plate surface to prevent passage of the fist. .
[0003]
[Problems to be solved by the invention]
However, when a fender is continuously provided at the lower end of the front hanging portion as in the prior art, the inner end of the fender comes into contact with the surface of the fabric foundation. If the fabric foundation is carefully finished here, there is no problem, but usually the fabric foundation is constructed by concrete casting on site, so the finishing accuracy is poor, the surface is uneven and unevenness occurs. There are many. For this reason, when the end of the fender is brought into contact with the surface of the fabric foundation, the entire draining material is bent due to the unevenness, and the finish is deteriorated and the appearance appearance is impaired.
[0004]
In view of such a point, the present invention is to provide a draining material that can always be finished with a clean finish without being affected by unevenness of the fabric foundation.
[0005]
[Means for Solving the Problems]
The technical means of the draining material of the present invention is a draining material for a floor underfloor ventilation method comprising a draining material body having a mounting portion, a rainwater guide portion, a front hanging portion, and a fender having a vent hole. The main body and the fender are made by bending one sheet metal having elasticity and processing the attachment part to be doubled, and the draining material body is bent from the lower end of the attachment part to guide rainwater Is further bent from the front end of the rainwater guide portion to form a front drooping portion, and the fender is located behind the front dripping portion of the draining material body and is the lower end of the other mounting portion that is doubled Further, the armor is provided in a cantilevered state, and the fender part is elastic so that , in use , the lower end comes into contact with the fabric foundation in the cantilevered state .
[0006]
In order to facilitate elastic deformation, a bent portion may be formed in the fender. Furthermore, for the ventilation wall construction method , it has an insect repellent part that is bent forward from the attachment part of the draining material main body , folded back at the front end, formed in a doubled manner, and formed with a vent hole. You may do it.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the draining material of the present invention will be described based on examples of the drawings. FIG. 1 shows a first embodiment in which the drainage material 10 is used. A foundation packing 3 is sandwiched between appropriate positions between the fabric foundation 1 and the base 2. For this reason, the part without packing becomes the ventilation gap 4, and underfloor ventilation is possible from here. 5 is a decorative mortar provided on the surface of the fabric foundation, 6 is a pillar, and 7 is an exterior material.
[0008]
The draining material is constituted by a main body 10 having a normal form including an attachment portion 11, an inclined rainwater guide portion 12, and a front drooping portion 13, and a fender 14. The fender part 14 is located behind the front hanging part 13 and has a shape that is continuously provided in a cantilevered state downward from the lower end of the attachment part 11. Further, the fender part 14 is formed with a large number of ventilation holes 15 that are large enough to prevent the passage of soot, as shown in FIG. 2, and can ventilate under the floor. The fender 14 is made of a material having moderate elasticity, and its lower end 16 always comes into contact with the surface of the fabric foundation 1, and if the surface of the fabric foundation is uneven, Will be deformed along. In the illustrated example, a bent portion 17 is formed to facilitate inertial deformation of the fender portion 14. Incidentally, draining material 10 of the illustrated example, Ru sheet metal der. In short, the fender part 14 has moderate elasticity, is always in contact with the fabric foundation, and may be deformed along the unevenness of the fabric foundation.
[0009]
FIG. 3 shows the second embodiment, which has no bent portion in the fender 14 compared to the first embodiment. FIG. 4 shows a third embodiment, which is used for a building of a ventilation wall construction method in which a ventilation gap 8 is provided on the wall. In order to prevent insects from entering the ventilation gap, the insect-proof part 18 protrudes from the attachment part 11. It is formed in a shape. As shown in FIG. 5, the insect-proof portion 18 is formed with a large number of ventilation holes 19 having a size that prevents insects from passing therethrough. For this reason, insect invasion can be prevented without impairing the air permeability into the wall.
[0010]
FIG. 6 shows a fourth embodiment. The fender portion 14 is provided with a bent portion 17 as compared with the third embodiment. FIG. 7 shows a fifth embodiment in which an insect repellent portion 18 is provided on the back side of the attachment portion 11. FIG. 8 shows a sixth embodiment having no bent portion.
[0011]
The present invention is not limited to the above-described embodiments, and can be freely modified within the scope of the claims. In particular, the material and shape of the drainer main body 10 and the fender 14 are free, and the shape of the vent hole 15 is also free.
[0012]
【The invention's effect】
The draining material of the present invention is made of a single sheet metal having elasticity. That is, first, the sheet metal is folded to make the mounting portion a double structure, and the tips thereof are bent to form the draining material body and the fender. As a result, the draining material is integrated as a whole, so there is no need to assemble a separate element at the time of manufacture, and the manufacturing process can be simplified. The work can be performed easily, for example, the entire position can be aligned by simply contacting the foundation. In addition, since the fender is elastic and is supported in a cantilevered state , its lower end always comes into contact with the fabric foundation. Can be deformed. Furthermore, since the whole is made of one sheet metal having elasticity, the draining material body also has elasticity. For this reason, even if it collides with something at the time of use, it hardly deforms and can retain its original shape for a long period of time. Also, since the fender is located behind the front hanging part of the drainer body, the deformation of the fender is not visible from the outside, and the deformation of the fender does not affect the drainer body. The appearance of the construction of the material will not be impaired.
[0013]
According to the second aspect of the present invention, the insect-proof portion is integrally formed in front of the mounting portion, and when used in the ventilation method, insects can be prevented from entering the ventilation gap of the wall without impairing the air permeability. It is beneficial.
[0014]
According to the third aspect of the present invention, the insect repellent part is integrally formed on the rear side of the attachment part, and when used in the ventilation method, it is possible to prevent the insect from entering the ventilation gap of the wall without impairing the air permeability. It is beneficial.
