Description

  The present invention relates to a building part formed using a combination of three wooden blocks made of thinned wood or the like.

Regarding the conventional technology, several building structures for processing and assembling wood for promoting the use of thinned wood have already been devised. For example, there are a device for connecting four block members in a cross shape, or a wall surface member made of small-diameter wood and a wall surface structure using the same.

  All the problems that the conventional techniques are trying to solve are aimed at promoting the use of thinned wood. The present invention also uses low-value thinned wood left as it is in forests, fallen trees exposed to natural disasters, and scraps and short woods that appear frequently in the lumbering process and construction sites. Build building structures. However, the conventional building structure has a problem in that it is converted into an industrial product, and there is room for improvement.

  Therefore, the present invention provides a building part formed from three wooden blocks having the kind and quantity suitable for commercialization, quality, strength, and beautiful grain of wood, and furniture materials that can be made using the building part, The issue was to provide architectural interior materials and structural materials for wooden buildings.

  First, using thinned wood with low utility value, manufacture three wooden blocks that can be divided into a plurality of vertical vertical surfaces in a vertical rectangular parallelepiped with a given length of bottom. To do. Each of these three wooden blocks has a different shape, but each includes a vertically long triangular prism whose bottom surface is a right triangle. That is, the first block is a right triangular prism, the second block contains two right triangular prisms, and the third block is one fifth of the right triangular prism and the rectangular parallelepiped. Three wooden blocks containing a vertically long rectangular parallelepiped with a volume ratio of 1: 2: 2.

  Next, a semicircular groove is processed over the entire length along the long side at two positions respectively at the same position on the four rectangular side surfaces of the vertically long rectangular parallelepiped. The size of the groove is 1/20 of the length of the short side of the rectangular side surface. The cuboid 6 surface including the grooving and the grooving surface requires extremely high processing accuracy. However, since it is an outer shell surface, it can be processed relatively easily if it is mechanized. Three wooden blocks have two or more of these semicircular grooves.

  Now, in principle, three wooden blocks are overlapped to make a combined building part, and then the surfaces with grooves are bonded together. At this time, no adhesive should be applied to the semicircular groove. This is because a circular through-hole formed when two semicircular grooves overlap each other plays a role of connecting short materials. At this time, among the three wooden blocks, a wooden block having two bonding surfaces and having four semicircular grooves is a central block of the combination. An architectural part formed from three wooden blocks, characterized in that it has 2 (n-1) circular through-holes by adhering n wooden blocks.

Next, a method for longitudinal joining in the longitudinal direction will be described.
First, a hardwood plug driving joint using a through hole will be described. Use hardwood plugs that are harder, more resilient, and more flexible than materials. The shape of the hardwood plug is a round bar, and the size is about 5% higher than the through hole. The strength of this joining method cannot be expected, but anyone can easily process it, and it can be reused by returning it to its original shape at any time by moistening the periphery of the hardwood plug.

Furthermore, three methods will be described for longitudinal adhesive bonding in the longitudinal direction.
First, the vertically long bottom is cut at a right angle and bonded. The advantage is that it is easy to process, but the strength cannot be expected. Next, the vertically long bottom surfaces are cut obliquely and bonded together. The strength can be expected to be about the same as the material, but there is a material loss, so it needs to be considered. At the end, the vertically long bottoms are cut into fingers like hands and bonded together. This method is suitable for mechanization and can be expected to be stronger than the material.

  The present invention can also solve the disadvantages of wood during the manufacturing process. Of course, the rectangular parallelepiped with a square bottom is a solid material. By cutting it into three wooden blocks, it is possible to remove dead nodes and dry quickly. In addition, by combining and bonding the three wooden blocks, it is possible to prevent cracking, warping, twisting, and the like, and to ensure a quality suitable for industrial products. Furthermore, it is possible to further characterize the beauty of the wood, such as the mesh and the mesh that the three wooden blocks have.

  The basic dimensions of a vertically long rectangular parallelepiped used in the present invention will be described. In order to use thinned wood and fallen trees with low utility value, and sawmills that are discarded at the lumbering process or construction site, it is impossible to combine them into one. In view of this, a rectangular parallelepiped with five types of bottoms having a square shape was used. The five types are used even if they are too many, so the usage form becomes complicated. If the usage is considered to be a wide range, such as furniture materials, architectural interior materials, wooden construction materials, etc., 5 steps of rectangular parallelepiped with 120 mm square, 105 mm square, 90 mm square, 75 mm square and 60 mm square are required. .

  The type and amount of building parts formed by using the combination of wooden blocks of the present invention are six kinds of building parts by combining two wooden blocks. By combining three three wooden blocks, 16 kinds of building parts are formed in four ways. In principle, the combination of 3 and 4 has a wooden block having two adhesive surfaces as a central block. Similarly, 78 combinations with 5 combinations and 79 combinations with 6 combinations can form abundant building parts.

  As described above, the building parts formed by the combination of wooden blocks have a wide variety of shapes, and if you have the abundant building parts group, you will want to expand your creativity, and you will want to actually assemble it like a building block. For example, it can be used as a school material for children and as a material for familiar wooden furniture for baby boomers who are retiring. Furthermore, it can be provided as a structural material that can be used to show architectural interior materials, wooden pillars and beams. If demand in the market increases, it will be possible to stop the deforestation of planted forests all over the country after the war and be an effective improvement measure for forestry regeneration.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  From FIG. 1, in the vertically long rectangular parallelepiped 1 having a square bottom surface, the vertex ABCD and the center point abcd of each side are respectively connected. Using the line Ac, the line Bd, the line Ca, and the line Db, an intersection point e between the line Ac and the line Bd, an intersection point f between the line Ca and the line Db, and an intersection point g between the line Ac and the line Db are obtained. From the above, three wooden blocks formed by cutting along four vertically long surfaces with the lines Cf, fD, ge, and eB as cutting lines are manufactured as shown in FIG. That is, a wooden block 2 is formed of a vertically long triangular prism having a right triangle connecting the points CDf as a bottom surface. Next, a wooden block 3 includes a figure connected by the points ABegD as a bottom surface and includes two right-angled triangular prisms. Further, a figure connecting the points BCfge is defined as a bottom, and a wooden block 4 includes a rectangular prism and the rectangular parallelepiped 1 which is a fifth volume of the rectangular parallelepiped. The volume ratio of the wooden block 2, the wooden block 3, and the wooden block 4 is 1: 2: 2, and each shape is characteristic and optimal for combination.

Next, in the vertically long rectangular parallelepiped 1 having a square bottom surface, a groove for vertical contact is formed. As shown in FIG. 1, a semicircular groove 5 having a radius of 1/20 of the length of the short side AB is formed at two locations at one third of the short side AB of one rectangular side surface. Machining from end to end along the long side. The remaining three rectangular sides are similarly grooved. As described above, when the vertically long rectangular parallelepiped 1 is cut into three wooden blocks, the wooden block 2 and the wooden block 4 have one adhesive surface and two semicircular grooves 5, and the wooden block 3 has an adhesive surface. Will have four semicircular grooves 5 on two sides.

  As shown in FIG. 3, five types of rectangular parallelepipeds having a square bottom surface will be described. Five types of vertically long rectangular parallelepipeds are cut into three wooden blocks in the same procedure, and the three wooden blocks are characterized by having two or four semicircular grooves. And, as a general rule, three wooden blocks are overlapped for each type to make a combined building part. However, the formed building parts are used beyond the same kind of frame.

As shown in FIG. 4, the vertical joint using a hardwood plug between short building parts will be described. First, carefully slash one half of the length of the round timber bar prepared in all the through holes of one building part to the middle. The other half of the projecting part is carefully driven into the projecting remaining half-length Tamo laminated round bar until the building parts are joined together. At this time, it is important to moisten the through holes and the Tamo laminated round bar to prevent damage to the building parts.
