Description

[Detailed explanation of the idea] When constructing the exterior of a residence, etc., a plate-shaped wall material is attached to the construction base, but it goes without saying that in this case it is important to carry out construction with waterproofing in mind. do not have.

Conventionally, wall materials are constructed by overlapping the ends of the plates.

As shown in the sectional view shown in FIG. 1, since the wall materials were constructed by overlapping each other with their cut edges facing each other, rainwater could enter through the gap a due to capillary action.

The present invention has been devised in order to perform a cohesive joint without the intrusion of rainwater etc. due to such capillary action.

Therefore, at least one cut edge of the notches in the wall materials that are stacked one on top of the other is provided with a slope that cuts inward, and the tip thereof is butted against the cut edge of the other wall material, and the overlapping surface It is characterized by the fact that it is coated with caulking material.

This will be explained below with reference to the drawings. FIGS. 2A, 2B and 2C are sectional views showing different embodiments of the present invention.

Figure A shows an example in which only the cut end of one of the wall materials 1 and 2 is inclined.

That is, the wall material 1 has been subjected to edge processing for normal mating, and the back surface of the wall material 1 that comes into contact with the rim 3 is the wall material 1.
About half of the thickness of the plate is cut out to form a stepped portion 4.

The wall material 2 facing this has, conversely, a stepped notch 4' on the opposite side of the rim 3, that is, on the surface side of the wall material 2.

The cut edge 5 on the surface side of the wall material 2 of the stepped portion 4' is formed to be inclined so as to cut inward.

Therefore, when construction is carried out in tandem, a butt is formed at the part 6, and a seam is formed, but this is no different from the normal case as far as it is viewed from the surface side.

This abutment is not a strict adhesion, but a temporary connection, and a slight gap may occur depending on the construction accuracy or the machining accuracy of the wall material.

However, in most cases, it only serves to prevent rainwater from flooding.

By forming a wide gap 7 inwardly, this acts to cut off the capillary tubes that allow rainwater to enter.

Therefore, rainwater and the like will not enter the interior beyond this point, making it effective for waterproofing.

Figure B shows a case in which the abutting cut ends of both wall materials 8 and 9 are formed as slopes that cut inward, and the gap 7 formed inside is made wider to make it easier to cut the capillary. Alternatively, by making the slope of the cut end more gentle, the sharpness of the light end 10.10' of the cut end can be made blunt.
To obtain a certain necessary air gap 7 while preventing damage such as chipping.

Note that 11 in Figure B indicates a caulking material for further enhancing the waterproof effect.

Figure 0 shows the cut end cut into a truncated shape instead of a wedge-shaped point and a flat surface 1.
2 is shown to prevent chipping from occurring.

Note that the joints on the surfaces of the furring 3 and other surfaces that come into contact with the construction base may also be made transparent.

In summary, the present invention provides an inclination that cuts inward at at least one cut end of the notches in wall materials that are stacked one on top of the other, and the tip thereof abuts against the cut end of the other wall material, and The feature is that a caulking material is provided on the overlapping surfaces, so the abutting part of the surface has the effect of blocking water, and then the internal gap blocks water that has entered due to capillary action. It has a heavy waterproof effect.

Moreover, the water that enters due to capillary action is blocked in the middle of the joint surface (edge surface of the joint), so the waterproofing effect is even greater.
