[0002]

2. Description of the Related Art In afforestation of cedars, cypresses, pine trees, etc., seedlings are densely planted at first, but after about 10 years, they are bred and hindered in breeding. A thinned log is obtained by cutting a thinned tree to an appropriate length. Trees cut and cut from the forest are called logs, the thicker cut at the base is called the original mouth, and the thinner cut at the end of the trunk is called the end, but logs are distinguished by the diameter of the end. . That is, a small log, 14 ~
Those with 30 cm are called medium logs, and those with 30 cm or more are called large logs. Thinned logs correspond to small logs and thin middle logs. The diameter of the end of the lumber determines whether it will be square or plate, but the small diameter logs are too thin to be square or plate.

Conventionally, peeled small-diameter thinned logs have been mainly used as logs for construction scaffolding or logs for piles or rice hanging. However, iron pipes have been used for these purposes. Since the automatic drying machine is used for drying the rice, the thinned thinned logs have almost no use, and are used only for piles or the like. for that reason,
It is a fact that small diameter thinned logs are left inside the plantation.

[0004] In view of the influence of log houses in recent years, various proposals have been made using thinned logs as building materials having a similar appearance to log houses. For example, the invention described in Japanese Utility Model Laid-Open No. 60-179717 discloses a method in which a large number of pieces of wood obtained by cutting both sides of a log flat are arranged, and a thin joint material is fitted into each cut surface and connected to form a panel. In the invention described in Japanese Patent Application Laid-Open No. 58-156661, a large number of octagonal rods are cut out from the periphery, and joints are fitted and connected to form a panel. The invention described in Japanese Utility Model Application Laid-Open No. 01-48204 is a laminated material in which the same octagonal rods as described above are connected by an adhesive. Further, the invention described in Japanese Utility Model Application Laid-Open No. 61-43006 is a plate material obtained by sawing thinned logs into a board, arranging a large number of these boards and bonding them to a plywood board.
The device described in the publication is a panel formed by lumbering thinned logs into small quadrangular pillars and arranging and bonding a large number of them in a matrix. Also,
The present invention was filed on April 8, 1994 by the applicant as a patent application for a building material suitable for a wall or the like using a thinned log, and the present invention is an invention in which the overlapping method is different. The cut surfaces of two or more semi-cylindrical cylinders obtained by cutting into pieces are superimposed and fixed with a width in the range of 1 cm from the radius of the end so that the base and the end are alternately opposite. A column-shaped building material, and a panel-shaped building material in which a plurality of these are connected and fixed. The direction of the original opening is reversed on the front and back surfaces of this panel.

[0005]

The panel-like building material using the thinned log except the above-mentioned building material according to the application of the present applicant is obtained by cutting a side surface to a certain thickness. In particular, the invention described in Japanese Utility Model Laid-Open Publication No. 01-48204 discloses a structure in which only the octagonal surface that is cut off is visible, and is not a natural shape of a log as it is, so there is no natural beauty like a log house. is there. Showa 60-17
In the device described in Japanese Patent No. 9717, since both sides of the log are shaved, the roundness of the surface remains, but it is necessary to make the whole the same thickness in order to connect, and it is the same as the terminal end. Since both sides are shaved toward the base opening at the width, it is not the shape of the log itself, so an artificial feel is inevitable. The building material related to the application of the applicant of the present application is a thinning log as it is, and is a building material overflowing in nature, but the semicircular column on the back side has an inverted appearance because the end is downward. Therefore, in the case of an application showing both front and back surfaces, it is inevitable that there is some unnaturalness or unnaturalness on the back surface side. In the invention of other inventions, the lumber made of a plate or a square bar is used, so that the appearance is flat and is far from a log house-like attraction. These are also very expensive building materials because of the large number of sawing steps.

[0006] The present invention solves these problems, and differs from the conventional building materials utilizing thinned logs in that the natural appearance of unprocessed semi-cylindrical thin logs in the form of semi-columns dotted with nodes,
It is characterized by the fact that the end and the cut surface can be seen side by side in the same direction on both sides, and is also excellent in heat insulation, suitable for walls and partitions, etc. This will also contribute to the development of forestry by expanding demand for thinned logs.

[0007]

According to the present invention, a cut surface 2 of two semi-cylindrical columns 1 obtained by cutting a thinned thinned log in a vertical direction is used as an original opening 3.
Are the same direction, and are fixed so as to overlap in a predetermined range of width. The width of the predetermined range is the end 4
Side has a width of at least 1 cm. On the side of the base 3, the difference between the diameter of the base 3 and the end 4 and the sum of the overlapping width on the side of the base 4 indicate the value of the base 3. If the width is up to the radius and deviates from this range, a non-overlapping portion may be generated, the width of the fixing portion 5 may be small and the building material may be weak, or the cut surface 2 may be It does not overlap with the surface of the semi-cylindrical column 1 and does not become a high-quality building material. Further, the present invention is a panel-like building material in which the building materials obtained in this way are sequentially connected and fixed laterally at fixing portions 5 having a width in the above range. Thinned logs are cut into half cylinders 1 and half cylinders 1 and cut to a thickness of up to three-fourths of the diameter. In this case, the opposite semi-cylindrical column 1 has a thickness of approximately one-fourth or more of the diameter and an arc-shaped cross section.

FIG. 1 is a perspective view of a building material to which two semicircular columns 1 are fixed, and a thinned log is cut into two equal lengths.
The semi-cylindrical columns 1 are arranged so that the respective openings 3 are oriented in the same direction, and the cut surfaces 2 are superimposed on each other so that the distance between the center lines 6 is equal to the radius of the opening 3. By moving in parallel, the original port 3
In the width of the radius of the end 4, the width is twice the difference between the radius of the base 3 and the radius of the end 4 from the radius of the base 3, and overlaps with the elongated trapezoidal fixing portion 5. , This fixing part 5
Is fixed. The building material thus obtained has a natural appearance of the bark of the thinned log with dotted nodes 7 and a section 7 of the cut surface 2 excluding the fixed portion 5, that is, the heather appearance portion 8. It is a single pillar-shaped building material with a beautiful heather. Also, the use of three or four semi-cylindrical columns 1 is a somewhat wide columnar building material. If the cut of the thinned log is not a half of the diameter, for example, if it is cut to a thickness of two thirds of the diameter, a round bark with a truncated circular cross section and the heather grain appearance part 8 are arranged on the surface. The architectural material is visible on the back side, and on the back side, the wooden surface of the curved surface with an arc-shaped cross section and the heather eyes of the heather eye appearance portion 8 can be seen. A fastener such as a screw 9 or a nail or a bolt is used for fixing, but various adhesives are also used. As the adhesive, for example, epoxy-based Oshigadain 7030 (trademark), Stamic EA255A (trademark), urethane-based Takenate XA-W147NS (trademark), and other Fratac K-540 (trademark) are used.

In the case of superposition, if the fixing width is small, the thickness of the overlapped portion is small and the strength is inferior, so that the fixing width is limited. When the thickness of the thinned log is 270 cm in length, the difference between the diameters of the original mouth 3 and the end mouth 4 is usually about 3 cm. Therefore, the width obtained by subtracting 3 cm from the fixed width on the base opening 3 is the fixed width on the end opening 4 side. If the fixed width on the base opening 3 is 4 cm, the fixed width on the end opening 4 side is 1 cm. At the fixing width of 1 cm or less on the end 4 side,
Since the thickness of the overlapped portion is reduced and the strength is inferior, the fixing width is limited to 4 cm on the side of the base 3 and 1 cm on the side of the end 4. If the length is 210 cm, assuming that the difference between the diameter of the base 3 and the end 4 is about 2 cm, the side of the base 4 is 1 cm, and the base 3 is the end 3 The limit is 3 cm, which is the difference between the diameters of 4 and 2 cm plus 1 cm.

FIG. 2 is a perspective view of a panel to which several columnar building materials to which two semi-circular columns are fixed are fixed. Motoguchi 3
This is a panel-shaped building material in which a plurality of fixed building materials are arranged, and the cut surfaces 2 are overlapped and connected and fixed to each other at a fixing portion 5 having the same width. In this building material, both the front and back sides, the semi-cylindrical bark 1 and the surface 8
Appear alternately, and the semi-cylindrical column 1 is in a natural shape with the thick original opening 3 facing down, which is interesting. In addition, since the thickness of thinned logs is not always constant, there is also a case where various thicknesses are mixed and used, and those shown in FIG. 3A use thinned logs of various thicknesses. It is a very interesting building material with a change in the thickness of the semi-cylindrical column 1 and the width of the heat-exposed portion 8. Further, when a semi-cylindrical column 1 having a thickness of two-thirds of the diameter is used, as shown in FIG. The semi-cylindrical column 1 having the shape is a building material in which the naturalness is remarkably left alongside the heather appearance portion 8.

FIG. 4 shows a perspective view of a panel having a corner portion, in which two panels made by making the width of the fixing portion 5 equal to the radius of the main opening 3 on the side of the main opening 3 are set at an angle of 90 °. A corner member 10 in which a thinned log is vertically divided into four at the inner corner corresponding to
Is a panel having a corner portion obtained by fixing. In addition, there is also a panel having a shape bent at an angle of 60 ° using a corner member 10 obtained by dividing two panels vertically, for example, into six, instead of using 90 °. Some panels are bent at 120 °. Further, there is a panel having a U-shape or a Z-shape provided with a plurality of corner portions.

[0012]

The cut surface 2 is fixed so that the ends 4 of the semi-cylindrical columns 1 are overlapped so as to be in the same direction. Therefore, when viewed from the front side or the back side, the end 4 is directed upward. It is a building material with an interesting appearance in which the beautiful wooden skin with the semi-cylindrical columns 1 lined up and the nodes 7 are scattered, and natural heathers alternately appear, and a mixture of thinned logs with different thicknesses is mixed. The one used and the one using the semi-cylindrical column 1 which is cut at a location smaller than the radius of the end 4 are the thickness and roundness of the semi-cylindrical column 1,
The width of the heather appearance part 8 and the interval between the semi-cylindrical columns 1 are changed, so that it is very interesting and full of nature.

In use, the device may be used vertically, horizontally, or diagonally. A large number of columnar building materials are arranged at intervals, and the upper and lower sides are connected by a semi-cylindrical column 1 or an appropriate material to form a vertical bar or a horizontal bar. If it is interesting as a partition between seats and it has no legs, it will be more interesting if used as a partition between a lobby and a kitchen and a living room. Panel-shaped building materials as shown in FIG. 2 or panel-shaped building materials having corners as shown in FIG. 4 have sufficient thickness and strength, and are also excellent in heat insulating properties. It can be used as a ceiling to create a building with a log house-like feel.
