Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wall material constituting a wooden wall in residential construction and a method of using the same.

(Prior Art) Regarding constructing walls by stacking horizontally elongated timbers, there are the Shoso-in and other buildings that use square lumber with a triangular vertical cross section, and the Canadian House that uses logs.

In addition, there is temporary pasting for walls using board materials, which include:
There are vertical gluing, in which the lower end of a horizontally elongated rectangular plate is overlapped with the upper end of a similar plate, and horizontal gluing, which is a method in which longitudinally elongated rectangular plates are pasted together at joints.

(Problem to be solved by the invention) However, in Yokura-zukuri, square timbers with triangular vertical sections are simply stacked, and gaps are created between the square timbers, making it difficult to apply as a wall for residential construction. It is something that cannot be done.

In addition, Canadian houses are made of stacked logs, and although some measures have been taken to reduce the gaps between the logs, it is impossible to completely prevent rain and wind from entering. It is insufficient for residential construction.

On the other hand, temporary pasting is still used in Japanese residential construction, but vertical pasting requires waterproofing at the joints between the boards, and stacking requires applying waterproofing to the joints. Although caulking is mainly performed using silicone or the like, it not only takes a lot of time and effort to do the work, but it is also uneconomical because the walls are temporarily pasted only on the outer walls and it is necessary to apply the inner walls as well.

In view of the above points, an object of the present invention is to provide a wooden wall for housing construction that can prevent the intrusion of rain and wind without waterproofing, eliminates the need for internal walls, and can be fully adapted to the climate of Japan. It is something to do.

(Means for solving the problem) In order to achieve the above purpose, when constructing a wall by stacking horizontally long square timbers, the shape of the vertical cross section of the square timbers is divided into four corners of a square with a side of about 45 mm. ■Cut out an isosceles triangle of appropriate size with one corner as the apex angle, [2] Cut out a square with a side of about 5 ms at one corner located next to it so that the interior angles are the same. ,■ The remaining two corners are kept as they are at right angles, and the wall is stacked with the square cut part facing down and the triangular cut part facing indoors. I decided to configure it.

(Function) With the above configuration, the square cut part forms an inverted V-shaped concave part, and the tip of the corner that is located at the bottom end of the square timber and maintains a right angle is just convex. By overlapping the square timbers, the unevenness is combined, creating a structure that does not create any gaps and completely blocks out rain and wind.

Furthermore, since all of the triangular cut portions are directed towards the indoor side, the entire structure approximates a flat surface and can be used as an interior wall as is.

On the other hand, the exterior wall surface is different from a flat surface, as each side of the square timber forms an angle of 45 degrees or 135 degrees to the ground, so if the sun's altitude during the day is 45 degrees or more, more than half of the surface area of the exterior wall This creates a shadow, and when the temperature drops below 45 degrees, the entire surface of the exterior wall is exposed to the sun, which suppresses temperature rise in the summer and encourages this in the winter.

(Example) Embodiments of the present invention will be described below based on the drawings.

As shown in Figure 1, the longitudinal cross section of the horizontally elongated timber is cut out from one of the four corners of the square (in the shape of an isosceles triangle (3) with the apex angle 〇), and the one located next to it is cut out. Corner (4
) with the same internal angle as the square (0) and make it into a shape as shown in Figure 2. Turn the square piece thus formed into a shape as shown in Figure 3, with the square cut part facing down.
Stack the triangular pieces with the cut pieces facing indoors.

As a result, the square cut part ([IO becomes a concave part and is located at the lower end of the square piece, whereas the tip of the right-angled part located at the upper end of the square piece acts in the same way as a convex part, and the third
As shown in the figure, the concave part at the lower end of the square timber ■ and the convex part at the upper end of the square timber (8), and the concave part at the lower end of the square timber (8) and the convex part at the upper end of the square timber (9) are combined, respectively, and the outside and inside of the wall are combined. It completely blocks out the water and prevents rain and wind from entering.

Furthermore, by directing the triangular cut portion towards the indoor side, the indoor wall approximates a flat surface and can be used as an interior wall as is.

On the other hand, as shown in Figure 4, the shape of the outer wall is such that the sides of the square timbers that make up the wall are at 45 degrees or 135 degrees with respect to the ground.
In the summer, the sun's daytime altitude 00 is over 45 degrees, and one-half to two-thirds of the surface area of the exterior wall becomes a shadow, suppressing the rise in temperature and keeping the room cool. Since the altitude during the day is below 45 degrees, the sun hits the entire exterior wall, promoting a rise in temperature and making the interior warmer.

(Effects of the Invention) Therefore, if a wall is constructed using the wall material for residential construction according to the present invention, it is possible to prevent the intrusion of rain and wind without waterproofing, and the height of the sun during the day can be prevented. As the area changes, the area exposed to sunlight changes, becoming cooler in the summer and warmer in the winter, creating a high level of livability in Japan's natural climate.

In addition, since the material is wood, it is easy to work with, and since it can also be used as an inner wall, work efficiency is high, and costs are reduced.
Needless to say, it saves labor, etc., and it is very economical, as it has an insulating property due to the property of wood, which does not allow heat to pass through, and it can save a lot on heating and cooling costs.
