Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wooden panel formed using thinned wood or the like.

(Background technology and problems to be solved) Wood is used as a building material for houses, etc., and although good woods such as cypress and cedar are often used, the value of wood from thinning has decreased significantly and it cannot be used as a building material. The forest is hardly ever used, and as a result, the forest is not properly maintained, such as thinning, and used wood and miscellaneous trees are left alone.

As a result, the mountains have fallen into disrepair, and the reality is that Japan's future building materials will not be cultivated, and that we will have no choice but to rely on foreign materials.

In view of this situation, the inventor of the present invention decided to use these thinned materials,
The present invention was developed after studying ways to effectively utilize used wood, miscellaneous trees, etc., as building materials, etc.

That is, the present invention utilizes materials that are not normally used for construction materials, such as dried thinned wood, used wood, and miscellaneous trees, and can be used as wall materials, roof materials, floor materials, etc.
The purpose of the present invention is to provide a wooden panel that can be used as a material for furniture, fittings, etc., and has excellent earthquake resistance as a building material.

(Means for Solving the Problem) The present invention has the following configuration to achieve the above object.

That is, wood such as thinned wood, used wood, miscellaneous wood, etc. is formed into unit block materials having an H-shaped cross section, and the unit blocks are arranged alternately in the direction of the end of the wood, and are provided on the outer surface of each unit block material. The concave grooves are arranged so that they communicate in series, and one side edge of the connecting material is fitted into the connected grooves by spanning between the unit block materials, and the other side edge of the connecting material is inserted into the connected grooves. Insert into the concave groove of the unit block material,
It is characterized in that each of the unit blocks arranged vertically and horizontally and between the unit blocks and the connecting member are joined with an adhesive to be integrated.

(Function) The unit block materials have an H-shaped cross section, and connecting materials are inserted into the grooves on the outer surface of the unit blocks to join them together. This makes it possible to firmly join the unit blocks of wood together, and also to alternate the direction of the ends of the wood, making it possible to use internal forces such as warping of the wood to obtain a strong wooden panel as a whole. .

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

Figures 1a, b, and c show an embodiment of the wooden panel according to the present invention, showing a front view, a top view, and a side view, respectively.

A wooden panel is constructed by combining a plurality of unit blocks formed into blocks to form a flat plate of a predetermined size. 10 and 12 in the figure
are the two types of unit block materials that make up the wooden panel.

FIG. 2 shows the unit block material 10 alone. As shown in the figure, the unit block material 10 has grooves 14 formed in the center of the upper and lower surfaces, and has an H-shaped cross section. The illustrated unit block material 10 has a butt end, and a hole 16 of a predetermined diameter is bored in the center of the butt end. This hole 16
As will be described later, this is for inserting a connecting rod used to connect the unit blocks 10 in the longitudinal direction. Note that this hole 16 is also provided to prevent the core of the unit block material from cracking by partially hollowing out the core of the end. In addition, hole 16
may be provided to penetrate the core portion. Also, in the figure 1
Reference numeral 8 designates bolt holes provided through the upper and lower surfaces of the unit block material 10.

The wooden panel shown in FIG. 1 is integrated by adhering and fixing each unit block material using an adhesive. Here, the unit block material 12 is formed so that the front exposed surface is the end, and the direction of the end is different from that of the unit block material 10. in this way,
The reason why unit blocks of different types are used is to obtain greater strength as a whole by combining different materials. Another problem is that it is difficult to bond the ends together, so unit blocks of material with different end orientations are joined together.

The unit blocks 10, 12 are arranged alternately as shown in the figure, and the unit blocks 10, 12 are bonded and fixed with an adhesive. Unit block material 10, 12
When arranged in a row, the grooves 14 become continuous grooves. 20 is a connecting member that fits into this groove 14. When the unit blocks 10 and 12 are stacked upward, the connecting member 20 is inserted between the stages, and the upper and lower unit blocks are positioned and joined using the connecting member 20.

As the connecting material 20, wood used as a unit block material may be used, or depending on the purpose of use, synthetic resin, steel material, etc. may be used.

Incidentally, in order to increase the joint strength of the unit blocks 10 and 12 in the vertical direction, the bolts 22 may be inserted into the bolt holes 18 of the unit blocks and tightened. It is best to use refillable bolts. The effects of bolting include the ability to increase the strength of the panel by inserting bolts, and the ability to hold the unit blocks together until they are completely joined. It will be done.

Furthermore, when joining the unit block materials 10 and 12 in the horizontal direction, the unit block materials 1
The connecting rods 24 are inserted into the holes 16 from the end faces of 0 and 12 and connected to each other.

By connecting as described above, the unit blocks 10 and 12 are completely connected in the vertical and horizontal directions and become one body, forming a panel of a predetermined size. As can be seen from the above forming method, the size of this wooden panel can be freely set depending on the number of unit blocks 10, 12 used. This makes it possible to provide panels of appropriate sizes depending on the application.

When joining the unit blocks 10 and 12, as shown in FIG. 1, the end of the connecting member 20 is slightly protruded from one end of the panel, and a tenon into which the connecting member 20 can be inserted is formed at the other end of the panel. It is preferable to form a portion 26. At the construction site, connecting material 2
By fitting the protruding portion of 0 into the tenon portion 26, a reliable connection can be achieved, and it can be easily used even on a large area such as a wall surface.

The size of the unit block material in the example is as follows: unit block material 10 with the end of the joint as the joint surface has a length of 120 mm, height and thickness of 100 mm, groove width of 15 mm, and unit block material 12 with the end of the end as the exposed surface; The length, height, and thickness are each 100 mm, and the groove width is 15 mm. The size of the unit block materials 10 and 12 is not particularly limited, but since the unit block materials may be small in size, they can be used even when good quality materials cannot be obtained, such as thinned wood or miscellaneous trees. It can be easily obtained as a unit block material and can be effectively used for the wooden panels mentioned above.

In addition, when using thinned wood, used wood, miscellaneous wood, etc., the material cost is low, and it is possible to provide the material at a cost that is slightly higher than the processing cost for processing the wooden panel. The processing of forming wood into blocks as described above can be done extremely easily using a woodworking machine, and when forming panels, the work is also easy because it is only necessary to join the unit blocks together.

In addition, when shaping wood, it is necessary to dry it to a certain degree and prevent it from being wrapped before shaping, but it is also possible to use unnecessary wood and dust left over from the process as fuel for drying. It can be done, and there is no waste from this aspect as well.

In addition, it is desirable to use various types of wood in the wooden panel from the viewpoint of increasing the strength of the panel, and as a result, there is an advantage that the unit block material can be used regardless of the type of wood used.
In the example above, the strength of the panel was increased by using wood with a different end direction, but in the same way, when different types of wood are used, the strength of the panel is increased by taking advantage of the differences in their properties. be able to. In other words, the meaning of using wood with different properties as a unit block material is to obtain different properties by changing the direction of the end of the wood, and to obtain different properties due to different types of wood itself. This creates a synergistic effect.

As described above, wooden panels are formed into a flat plate shape and have extremely high strength, and can be used extremely widely as building materials. For example, it can be used as residential wall materials, floor materials, ceiling materials, roofing materials, partitions, furniture, and general construction materials. In particular, wooden panels have high strength, so they can be effectively used as earthquake-resistant materials, and they also have excellent soundproofing performance.

The above-mentioned wooden panel may be used in a part that is not exposed to the outside, such as when used as a base material for a wall of a house, or it may be used as it is exposed to the outside. Wooden panels are made of various types of wood arranged in blocks, so a unique tile-like pattern appears on the surface, making them an interesting building material.

Furthermore, the above-mentioned wooden panel may be used as a core material for construction materials, and as shown in FIG. It can be used as an exterior material by finishing it with resin coating or the like.

In the above example, all the wooden panels were formed by combining unit block materials, but if a part of the wooden panel is made of long shaped members as shown in Figure 4, the strength can be further increased. It is effective and can be improved. Fig. 4b shows a state where a square piece is taken from a log, and Fig. 4a shows a state where the square piece is shaped into an H-shaped cross section. warp,
In order to correct distortion and gain strength, the square timber is divided into two halves at the center and joined in opposite directions. Depending on the case, different materials may be bonded together. When such an integrated product is used as a part of a wooden panel, it is effective because the strength of the unit blocks can be further strengthened by joining and integrating them.

As is clear from the above manufacturing method, the wood used for the wooden panel may be any type of wood, including cedar, cypress, red pine, black pine, Japanese pine, and other coniferous and deciduous trees. Additionally, split lumber made by splitting large-diameter lumber can also be used. As a result, the above-mentioned wooden panels can effectively utilize wood that has traditionally been neglected as a building material, such as thinned wood, used wood, miscellaneous wood, etc.
This has the effect of making it possible to perform forest maintenance such as thinning.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the invention) As mentioned above, the wooden panel according to the invention has
Since the unit block materials are arranged alternately in the direction of the end, and the connecting material is inserted between the unit block materials to connect them, internal forces such as warping of the unit block materials act on each other and the whole It can be obtained as a very strongly integrated panel. This allows it to be suitably used as a structural material such as wall materials and floor materials for residential buildings.

In addition, since the unit blocks are made from thinned wood, used wood, miscellaneous wood, etc., which have rarely been used as building materials in the past, they can be made at low material costs.

Additionally, the use of thinned wood, etc., which is available throughout the country, has great effects, such as being useful for maintaining mountain forests.
