Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a retaining wall block. In particular, the present invention relates to a retaining wall block formed by combining a plurality of timbers made of thinned wood.
[0002]
[Prior art]
Conventionally, a concrete retaining wall formed by assembling a formwork and placing concrete on a slope beside a road, such as a mountainous area, or a concrete retaining wall formed by combining concrete blocks, prevents disasters such as landslides. Yes.
[0003]
Such concrete retaining walls are common. The present applicant is not particularly aware of any literature specifying this.
[0004]
[Problems to be solved by the invention]
However, these concrete retaining walls were exposed to the surface of the concrete, and the appearance was unnatural due to the appearance of the surrounding natural environment. In addition, these concrete retaining walls provided the safety of the surrounding area, but also destroyed the living environment of animals and plants, leading to the destruction of the natural environment. Further, when concrete is driven into the mold, it takes time and labor to assemble and remove the mold, and it is also dangerous. Furthermore, when combining concrete blocks, the mass of the concrete blocks to be handled is large, and this also takes time for construction and is dangerous.
[0005]
Conventionally, there is a structure in which landslides are prevented by a wooden fence made of wood instead of the concrete retaining wall described above. However, it is easy to construct wooden fences on a certain flat slope, but it is difficult to arrange along a terrain like a concrete block on a slope that curves in the front-rear direction. . In addition, it was necessary to fasten with bolts and nuts at the time of construction, which took time and labor.
[0006]
In view of the above circumstances, an object of the present invention is to provide a retaining wall block that is gentle to the natural environment, matches the surrounding landscape, and can cope with terrain that curves in the front-rear direction. .
[0007]
[Means for Solving the Problems]
The retaining wall block according to the present invention is a retaining wall block having a block body formed by combining a plurality of timbers made of thinned wood, and forming a retaining wall by connecting a plurality of timbers. The main body has a first scissors insertion hole for allowing the scissors to pass in a direction parallel to the installation surface of the retaining wall, and the first scissors insertion holes of the adjacent block main bodies are continuous with each other, and are continuous with each other. The main means for solving the above-mentioned problem is to “connect the block bodies adjacent to each other by inserting the collar through the first collar insertion hole”.
[0008]
In the retaining wall block according to the present invention, the block body is erected on the installation surface, and a plurality of the retaining walls are continuously formed to form the retaining wall. The method of stacking the retaining walls when forming the retaining walls can be the same as when stacking the concrete blocks. The front shape of the block body may be, for example, a square including a square or a rectangle, or a triangle including a regular triangle or an isosceles triangle. When the front shape of the block body is square or rectangular, how to pile up the piles so that the joints of the upper and lower block bodies form a straight line, or the valley piles that pile up so that the joints of the upper and lower block bodies are corrugated Can be used. Here, trough stacking has the effect of strengthening the entire retaining wall by engaging the retaining wall blocks and the effect of efficiently distributing the load applied to the upper retaining wall block to the two lower retaining wall blocks. Since it is obtained, it is particularly suitable when constructing a retaining wall. When the block body has an equilateral triangle or an isosceles triangle, the block body is arranged so that the base is straight, and a block body in the opposite direction is further arranged between the adjacent block bodies. Can be used.
[0009]
When forming the retaining wall, whether the cloth pile, valley pile, or other stacking method is adopted, the openings of the first hook insertion holes of the adjacent block main bodies are made to coincide with each other. The retaining wall is formed as a continuous line. Here, the first scissors insertion hole may be formed by, for example, a plurality of wood gaps forming the block body, and is formed by drilling a plurality of wood forming the block body. It may be. Further, the first hook insertion hole only needs to allow the hook to be inserted in a direction parallel to the installation surface of the retaining wall. For example, a hole penetrating in the vertical direction of the block main body or a hole penetrating in the horizontal direction of the block main body Any of those penetrating in the diagonal direction of the block body may be used. Furthermore, the first scissors insertion hole may be used to insert a single scissors, or may be used to insert a plurality of scissors.
[0010]
Adjacent block main bodies are connected by inserting rod-shaped scissors through the first scissors insertion holes that are continuous with each other, but the scissors that are inserted are almost the same as the vertical width of the opening of the first scissors insertion hole. It is preferable to form with thickness. This is because the first hook insertion hole can be inserted and the movement in the first hook insertion hole is limited by friction. However, the thickness and shape of the ridge are not particularly limited. For example, when the slope is curved in the front-rear direction, the adjacent block main body is not arranged in a straight line, and the opening of the first hook insertion hole may not always be continuous, but in such a case For example, it is only necessary to select a ridge appropriately and insert it into an adjacent retaining wall block, such as using a fold thinner than usual or a fold having a round cross section. Further, the length of the ridge may be any length necessary for penetrating two block bodies, or a length necessary for penetrating three or more block bodies.
[0011]
Thus, the retaining wall block according to the present invention has a wooden block body, so that even if the retaining wall is formed, the concrete is not exposed like the conventional concrete retaining wall, and the surrounding natural environment Can keep the harmony in appearance. In addition, in the slope where the entire surface is completely covered with concrete or concrete block, there is a possibility of destroying the living environment of animals and plants or hindering drainage, but the retaining wall block according to the present invention, Since the block body is made of wood, there is little possibility of destroying the living environment of animals and plants or inhibiting drainage. Further, in the case of a conventional wooden fence or the like, it is difficult to arrange along the terrain like a concrete block, for example, in a site that curves in the front-rear direction, but in the retaining wall block according to the present invention, Similarly, it can be arranged along the terrain, and it can be stacked in various ways, such as cloth or valley, like a concrete block. This is advantageous. In addition, when connecting adjacent block main bodies, it is not necessary to fasten with bolts and nuts because it is connected by inserting a scissors through the first scissors insertion hole, and it can be easily constructed without trouble in the field. .
[0012]
By the way, when afforested trees grow and the branches touch each other, competition between adjacent trees intensifies, leading to inferior growth, inferior trees wither, and individual trees also grow. Decline, become susceptible to pest damage, wind damage, snow damage, etc. For this reason, it is necessary to reduce the density of the forest by cutting a part of the trees, to promote the growth of the remaining trees by relaxing the competition, and to nurture the entire forest in a healthy manner. This is called thinning, but the large amount of thinning that occurs at this time is often inferior trees, damaged trees, poorly formed trees, poorly shaped trees, withered trees, etc. As a building material, its value is low. In addition, because the trees are not sufficiently grown, it is difficult to use if the material is large and warped during drying. In the retaining wall block according to the present invention, the plurality of timbers forming the block main body are not a long material like a building material but a short material, and therefore, a thin and thin portion of the thinned material is normally cut and used. Is possible. Therefore, a new use of thinned wood has been developed, and effective utilization without waste of planted forest resources can be achieved.
[0013]
The retaining wall block may be “the block body further includes a second scissor insertion hole for allowing the scissors to be inserted in a direction perpendicular to the installation surface of the retaining wall”.
[0014]
By doing in this way, it becomes possible to penetrate the block main body in a direction perpendicular to the installation surface of the retaining wall and embed a part of the cage in the ground. Therefore, the position of the retaining wall block can be fixed by the eaves inserted vertically with the installation surface of the retaining wall. Here, when forming the retaining wall, it may be inserted through the second hook insertion hole of all the block body, but doing so will take time and work, so the bottom block body etc. It is also possible to insert a ridge in a direction perpendicular to the installation surface only. Further, the second scissors insertion hole may be formed by, for example, a plurality of wood gaps forming the block body, and is formed by drilling a plurality of wood forming the block body. There may be. Furthermore, the second scissors insertion hole may be used to insert a single scissors, or may be used to insert a plurality of scissors.
[0015]
The retaining wall block is described as follows: “The block main body is a first structure formed by combining a plurality of the woods and a second structure formed by combining a plurality of the woods and stacked on the first structure. And a third structure formed by combining a plurality of the woods and stacked on the second structure ”.
[0016]
By doing in this way, a block main body will be formed by laminating | stacking at least three structures which combine a some timber. The 1st thru | or 3rd structure which combines several timber is not specifically limited, For example, from the thing which consists of the timber arranged in parallel by the appropriate space | interval, and the timber combined so that the triangle may be made And the like. When the first hook insertion hole of the block body is formed in the second structure by the first structure, the gap between the plurality of woods of the second structure, and the third structure, the first hook insertion hole is easily Can be formed, which is more preferable. Here, the number of stacked structures is not limited to three, and four structures may be stacked, or four or more structures may be stacked. When four structures are stacked, the first hook insertion hole of the block body is formed in the second structure by the first structure, the gaps of the plurality of woods of the second structure, and the third structure. In addition, the second structure, the gap between the plurality of timbers of the third structure, and the fourth structure are also formed in the third structure, and for example, it is possible to insert ridges having different directions in different steps. Thus, for example, block bodies that are adjacent in the vertical and horizontal directions can be connected.
[0017]
The retaining wall block may be a "further provided with a lumber projecting from the block main body in a direction perpendicular to the installation surface of the retaining wall and partially embedded in the ground".
[0018]
In this way, when the bottom surface of the block main body is erected on the installation surface of the retaining wall, a part of the retaining wood is buried in the ground, and the position of the retaining wall block is fixed. Therefore, the retaining wall block can be reliably fixed to the installation surface of the retaining wall. Here, the holding wood may be extended from a plurality of woods forming the block body, or may be attached to the plurality of woods forming the block body. In addition, by placing a piece of wood perpendicular to the holding wood at the tip of the side of the holding wood that is buried in the ground, it is possible to embed wood in a different direction into the ground and fix the retaining wall block more firmly. You may do it.

Further, the retaining wall block 1 of the first embodiment has second collar insertion holes 24 and 25 in the block body 2 for allowing the second collar 27 to be inserted in a direction perpendicular to the installation surface of the retaining wall 4. . For this reason, the second rod 27 can be inserted into the block main body 2 in a direction perpendicular to the installation surface of the retaining wall 4 and a part of the second rod 27 can be buried in the ground. Therefore, the position of the retaining wall block 1 can be fixed by the second rod 27 inserted perpendicularly to the installation surface of the retaining wall 4.
[0040]
In the retaining wall block 1 of the first embodiment, the block body 2 is orthogonal to the first structure 5 composed of the woods 13 and 14 arranged in parallel at appropriate intervals, and the woods 13 and 14 of the first structure 5. A second structure 6 composed of woods 15, 16, and 17 arranged in parallel in the direction at appropriate intervals, and a third structure composed of woods 19 and 20 arranged in parallel in the same direction as the first structure 5 at appropriate intervals. 7. Thus, by stacking the structures so that a plurality of woods are alternately orthogonal, the first heel insertion holes 22 and 23 and the second heel insertion holes 24 and 25 can be formed with a simple configuration. .
[0041]
In addition, the retaining wall block 1 of the first embodiment includes a retaining wood 3 that protrudes from the block body 2 in a direction perpendicular to the installation surface of the retaining wall 4 and is partially embedded in the ground. For this reason, when the back surface 10 of the block main body 2 is erected on the installation surface of the retaining wall 4, a part of the retaining wood 3 is embedded in the ground, and the position of the retaining wall block 1 is fixed. .
