[Technical field to which the device belongs]

 The present invention relates to a draining material attached to a lower edge of an outer wall of a building such as a house, and mainly to a draining material used for a building having a basic packing method.

[0002]

[Prior art]

 At the lower edge of the outer wall of the building, a draining material is attached to guide the rainwater flowing down along the wall to the outside and to drip it. FIG. 8 shows an example of a conventional draining material 30. In the figure, 10 is a cloth foundation, 11 is a base, 12 is an exterior material, and 31 is a ventilation port. As can be seen from the shape shown in the drawing, the conventional draining member 30 has only a function of guiding the rainwater flowing down along the outer surface of the outer casing 12 and dropping it.

Further, in a conventional building, underfloor ventilation is usually performed by a ventilation opening 31 provided at an appropriate position on the cloth foundation 10 as shown in FIG. However, with this ventilation system, a stagnation area where air does not flow is created in a part of the floor, ventilation performance is not sufficient, and the foundation 11 is in contact with the cloth foundation 10, so that the foundation 11 is corroded. There is a problem that is likely to occur. Therefore, as a construction method for solving this, a ventilation construction method in which a synthetic resin base packing 13 is interposed between a cloth base 10 and a base 11 as shown in FIG. 9 is also often used.

[0004]

[Problems to be solved by the device]

 However, it is obligatory to take measures to prevent the entry of mice etc. into the ventilation openings under the floor. For this reason, even in the case of the above-mentioned basic packing construction method, the treatment is required, and usually, a method of attaching a rodent-proof rod-proof material to the opening is adopted. However, the method of mounting the rodent-proofing material separately from the draining material has the drawbacks of increasing the number of parts and requiring extra labor for construction.

In view of such a point, the present invention is to provide a draining material which is used in a basic packing construction method or the like and exhibits excellent functions. Further, the present invention aims to provide a draining material which can completely prevent invasion of a mouse and the like and can secure sufficient air permeability. Further, the present invention provides a draining material which can be easily installed and can be manufactured at low cost.

[0006]

[Means for Solving the Problems]

 The technical means of the draining material of the present invention has a mounting wall portion integrally formed of a thin material, an inclined protruding wall portion, and a bottom wall portion, and a mouse or the like enters the bottom wall portion. The number of vent holes is so large that a sufficient amount of air can be obtained, and further, the edge of the bottom wall portion comes into contact with the cloth foundation in the mounted state.

Further, a dimension mark for applying the decorative mortar may be provided on the bottom wall portion. Further, the bottom wall portion can be extended rearward for the ventilation wall construction method.

[0008]

[Embodiment of device]

 An embodiment of the draining material of the present invention will be described with reference to the drawings. FIG. 1 is an inclined view showing an end portion of the draining material of the first embodiment. The draining member 1 as a whole has a mounting wall portion 2, an inclined protruding wall portion 3, a protruding end wall portion 4, and a bottom wall portion 5. The draining member 1 is usually manufactured by sheet metal processing from a thin metal plate such as a thin steel plate, a thin aluminum plate, a thin stainless plate, or an extrusion process of an aluminum alloy or a synthetic resin material.

A large number of ventilation holes 6 are formed in the bottom wall portion 5. The size of the vent holes 6 is determined so as to prevent the entry of mice and the like, and the number of holes is determined so that a sufficient amount of ventilation can be obtained. For underfloor ventilation, it is required to provide a ventilation opening with an effective ventilation area of 300 cm ² or more within a gap of 4 m. Therefore, the hole diameter and the number of holes should be determined so as to comply with this. In the first embodiment, as shown in FIG. 3, 5 × 16 mm holes are continuously formed at 10 mm intervals. In the second embodiment described later, 8 × 12 mm holes are formed at 12 mm intervals. In FIG. 1, 7 is a convex strip for water repelling due to the capillary phenomenon, and 8 is a dimensional mark concave strip provided on the bottom wall 5 for applying decorative mortar.

FIG. 4 shows a state in which the drainer 1 is mounted and used. In the figure, 10 is a cloth foundation, 11 is a base, 12 is an exterior material, 13 is a basic packing, and 14 is a decorative mortar layer. The draining material 1 has its mounting wall portion 2 fixed to the base 11 by a nailing method or the like. When mounting the draining member 1, the draining member 1 is positioned so that the rear edge of the bottom wall portion 5 abuts on the upper edge of the cloth foundation 10 or in the vicinity thereof. The decorative mortar 14 is applied after the draining material 1 is attached. At this time, since the bottom wall portion 5 of the draining material 1 is provided with the mark concave streak 8, it is convenient to determine the coating thickness.

When the draining material 1 is attached, the rainwater that has flowed down along the outer surface of the exterior material 12 drops onto the inclined projecting wall portion 3 and is guided outward along the inclination, and the protruding end wall portion is formed. It will start dripping from the bottom edge of No. 4. Further, since the bottom wall portion 5 has a ventilation hole 6 and opens downward, outside air freely flows in through the ventilation hole 6 and the cloth foundation 10 formed by the foundation packing 13. It flows under the floor through the ventilation gap 15 with the base 11. Since the opening area of the ventilation hole 6 is large, the required underfloor ventilation area can be sufficiently secured. Further, since the individual hole diameters of the vent holes 6 are small, it is possible to prevent mice and the like from entering under the floor.

FIG. 5 shows a second embodiment of the draining material of the present invention. The draining material 21 of the second embodiment is a draining material for the ventilation wall construction method in which the ventilation layer 16 is provided on the outer wall. In this case, the bottom wall portion 5 is provided with the extension portion 22 corresponding to the ventilation layer 16 of the wall, and the bottom wall portion 5 is longer than that of the first embodiment. In the figure, 17 is a moisture permeable / waterproof sheet, and the gap between this sheet 17 and the exterior material 12 serves as the ventilation layer 16.

In the draining member 21 of the second embodiment, as shown in FIG. 6, the outside air entering from the ventilation hole 6 goes through the gap 15 to the underfloor and also to the ventilation layer 16 of the wall. Removes moisture from the body. The other functions of the second embodiment are the same as those of the first embodiment.

The draining material of the present invention is not limited to the above-mentioned embodiments, but can be freely modified within the scope of the claims of the utility model. In particular, the material of the draining material, the overall outer shape, and the size, number, and shape of the ventilation holes are completely free.

[0015]

[Effect of device]

 Since the draining material of the present invention has the bottom wall portion, it has a rodent-proof function in addition to the original function of draining. That is, since the lower surface of the draining member is shielded by the bottom wall and the vent hole formed in the bottom wall is small, it is possible to prevent a mouse or the like from entering the underfloor. In addition, since sufficient ventilation can be obtained with this ventilation hole, sufficient underfloor ventilation can be secured when used in a building with the basic packing method. Further, the draining material of the present invention has a simple structure, can be manufactured and provided at low cost, and is easy to install and is practically very convenient.

According to the second aspect of the present invention, since the bottom wall portion has the dimension mark, it is easy to set the coating thickness when applying the makeup mortar to the cloth foundation, and the construction becomes easy.

According to the third aspect, since the bottom wall portion extends rearward, it is suitable for the ventilation wall construction method, and the outside air entering from the ventilation holes of the bottom wall portion is supplied to both the underfloor and the wall. Can be sent.
