4 and attach the waterproof material 23 to the other stepped section 22.
Since the connecting portion of the exterior material 21 was only brought into contact with the connecting portion, drainage was not performed at all or was insufficient.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a drainage structure for exterior materials that has an excellent drainage effect at joints of exterior materials.

The present invention will be explained in detail below using examples.

The exterior material 1 is a plate-shaped body made of wood, gypsum board, or the like with an embossed pattern on the outer surface, and is engaged with the engaged recessed step portions 3 on the outdoor and indoor surfaces of both ends thereof. The recessed step portion 2 is recessed.

In addition, on the surface of the engaged recessed step 3 facing outdoors and the surface of the engaging recessed step 2 facing indoors, two inner waterproofing materials 5 and one outer waterproofing material are provided, respectively, as shown in FIG. 2a. Material 4 is attached.

The inner waterproofing material 5 and the outer waterproofing material 4 are made of an elastic material or a plastic material, and are provided over the entire length of the engaged recessed step 3 and the engaging recessed step 2 in the upper and lower directions.

Furthermore, both ends of the engaged recessed step 3 are finished with rounded chamfered portions 6 as shown in FIG. Furthermore, the inner corner of the engagement stepped portion 2 is finished with a rounded radiused portion 7, and the outer surface end of the exterior material 1 on the side where this engaged recessed stepped portion 2 is formed is finished with a chamfered portion 6. be.

The exterior material 1 formed as described above can be used as an exterior wall material for a house by attaching a large number of them to the exterior wall of a house, but when connecting the exterior materials 1 and 1 together laterally, , one exterior material 1 as shown in Figure 2.
The engaging recessed step 2 of the other exterior material 1 is engaged with the engaged recessed step 3 of 2, and the outer waterproof material 4 is meshed between the two inner waterproof materials 5.

In this way, the outer waterproofing material 4 and the inner waterproofing material 5 prevent water from entering the joint between the pair of exterior materials 1 and 1, and at this time, the water is removed between the outer waterproofing material 4 and the inner waterproofing material 5. A gap 8 formed over the entire length of the exterior material 1 blocks the so-called capillary phenomenon and prevents water from entering. , 1, even if rainwater enters from the outdoor side, the rainwater flows down through the gap 8, thereby more completely preventing rainwater from entering the back surface of the exterior material 1.

Figures 3a and 3b show other embodiments of the present invention, in which two outer waterproofing materials 4 and three inner waterproofing materials 5 are provided; 4 and two inner waterproof materials 5.

FIG. 5 shows an example of manufacturing the outer waterproofing material 4 and the inner waterproofing material 5. First, as shown in FIG. Next, this same resin is heaped up as the middle part 9 on the base 8 with a width narrower than the base part 8, and then the same resin is used as the tip part 1 on the middle part 9 with a width narrower than the middle part 9.
In this way, the outer waterproof material 4 and the inner waterproof material 5 can be formed to have a high height and a narrow tip through several steps of heaping up.

By the way, in order to bring the outer waterproof material 4 and the inner waterproof material 5 into close contact with the engaged recessed step 3 and the engaged recessed step 2, as shown in FIGS. 6a and 6b, the outer waterproof material 4 and the inner waterproof material 5 are It is preferable to increase the height and make the tip thinner, but as shown in Figure 6a,
It is difficult in terms of manufacturing technology to provide the outer waterproofing material 4 and the inner waterproofing material 5, which are raised high and have narrow ends as shown in b, on the exterior material 1 all at once.

Therefore, by making it in several stages as shown in Figure 5 at b and c, it is possible to build it up high and with a narrow tip, and in this way, the outer waterproofing material 4 and the inner waterproofing material 5 can be raised high and with a narrow tip. This makes it possible to use materials that are difficult to press and compress as materials for the outer waterproof material 4 and the inner waterproof material 5. An engaging recessed step 2 is provided, and an engaged recessed step 3 is provided on the outdoor surface of the other side end, and an outer waterproof material 4 and an inner waterproof material are provided in the engaged step 2 and the engaged recessed step 3, respectively. 5 is attached to form a plurality of at least one of the outer waterproof material 4 and the inner waterproof material 5, and the engagement recessed part 2 of one of the exterior materials 1 of the pair of adjacent exterior materials 1, 1 is formed. The outer waterproof material 4 and the inner waterproof material 5 are brought into contact with the engaged recessed step 3 and the engaged recessed step 2, respectively, to engage the engaged recessed step 3 of the other exterior material 1. Since the outer waterproof material 4 and the inner waterproof material 5 are interlocked and cut, the meshing of the outer waterproof material and the inner waterproof material results in multiple drainage of water from both waterproof materials, and water drainage at the joint of the exterior material. can be carried out reliably.

Furthermore, since the outer waterproof material and the inner waterproof material are respectively attached to the surface of the engaging recessed step facing indoors and the surface of the engaged recessed step facing outdoors, the engaging recessed step and the covered surface are respectively attached. When engaging the engagement recessed steps and bringing the outer waterproof material and the inner waterproof material into contact with the engaged recessed step and the engaging recessed step, respectively, the outer waterproof material and the inner waterproof material are connected to each other in the indoor and outdoor directions. Therefore, even if the exterior material expands and contracts in the width direction due to temperature changes in the outside air, the engaged recessed step and the engaged recessed step will contact each other. The outer waterproof material and the inner waterproof material will not come out of contact with each other, and there is no risk that the water draining effect of the outer waterproof material and the inner waterproof material will be reduced.

In addition, since the outer waterproof material and the inner waterproof material are made to mesh with each other with a gap between the outer waterproof material and the inner waterproof material, there is no space between the outer waterproof material and the inner waterproof material. The gap formed along the entire length of the building blocks the so-called capillary phenomenon and prevents water from entering.In addition, this gap acts like a gutter and prevents rainwater from entering between the exterior materials from the outside. However, the gap allows the rainwater to flow downward, making it possible to more completely prevent rainwater from penetrating into the back of the exterior material.
