Description

[Detailed description of the invention] The present invention is an earth retaining fixing block, in particular, a block for securing earth retaining material, which can be easily and stably attached to the slope of a mountainside between the ends of log materials used for earth retaining formed using log materials. This relates to earth retaining fixing blocks for connecting and fixing.

Traditionally, earth retaining has been formed on collapsed slopes such as mountainsides using various ready-made wooden frames and concrete blocks, but in both cases, it takes too much time and effort to form earth retaining, and This method has disadvantages such as the increased cost of materials for forming the fasteners.

Therefore, the inventor of the present invention realized that if inexpensive log materials such as thinned logs, which are currently in low demand and difficult to dispose of, are effectively used as earth retaining materials, earth retaining formations can be easily and inexpensively formed on collapsed slopes. To achieve this goal, we developed an earth retaining block using logs that can easily stabilize and secure the end portions of logs piled up along the slope of a collapse.

In other words, the purpose of the present invention is to be able to easily and stably fix each end of logs such as thinned logs piled up along a collapsed slope to a predetermined location on the slope, and to secure the ends of logs piled up along a collapsed slope. A substantially rectangular parallelepiped-shaped block is provided on the bottom surface of the block, which can easily and stably connect logs to be connected, and the end portions of each of the three sides intersect the ridgeline portions of the three sides of the block at approximately right angles. A concave groove is carved into which a T-shaped bar is inserted,
Further, a short T-shaped protrusion that can be fitted into and locked into the T-shaped groove on the lower bottom surface of the block is provided at a portion of the upper surface of the block opposite to the T-shaped groove on the lower bottom surface of the block. To provide a protruding earth retaining fixing block.

Hereinafter, embodiments of the present invention will be described according to the drawings. Figs. 1 and 2 show an earth retaining block formed using the earth retaining fixing block (hereinafter referred to as block) 10 of the present invention. , Block 1 of this invention
0 has a substantially rectangular parallelepiped shape as a whole, and has three end portions 14a, 14b, and 14c on its lower bottom surface 12 at right angles to each ridgeline 16 of the block, as shown in FIGS. 3 to 5. A concave groove 20 is cut into which intersecting T-shaped logs 18a and 18b such as thinned timber are inserted. Further, the T of the lower bottom surface of the block 10 on the upper surface 22
At a portion opposite to the T-shaped groove 20, there is also a T which can be fitted and locked into the T-shaped groove 20 on the lower bottom of the block.
A short, letter-shaped protrusion 24 is provided in a protruding manner.

The block of the present invention has the above-mentioned structure and is made of concrete or the like. When using the block, as shown in FIGS. When stacking logs horizontally along 26 to form earth retaining, logs 1
8a to the lower bottom surface 12 of each block.
The log material 18a is inserted into the horizontal groove 20a of the T-shaped groove 20 that crosses the lower bottom surface of the block, and the end of the log 18a is fixed to the block 10. An inclined surface 26 forming an earth retaining portion at a portion of the vertical groove 20b that intersects with the vertical groove 20b.
Each end portion protruding into the slope surface of a plurality of logs 18b, such as thinned wood, buried approximately vertically in advance for fixing blocks is inserted and fixed, and the logs 18b are fixed.
The block 10 is fixed to a predetermined portion of the inclined surface 26 through the screws. At the same time, the concave grooves 20 in the lower bottom surfaces of the upper blocks of the plurality of adjacent blocks 10 fixing the respective ends of the logs 18a stacked along the slope 26 to predetermined portions of the slope There is a T-shaped protrusion 22 on the upper surface of the block at the bottom.
The plurality of blocks 10 are stacked in a line along the inclined surface 26 by fitting and locking the adjacent blocks 10 so as not to move back and forth or left and right.
Then, each of the logs 18a stacked laterally along the slope 26 passes through the block 10 and the logs 18b buried in the slope in advance to the slope 26.
It is fixed in a predetermined position of the log 18a so that it does not move, and it is not easily moved between the plurality of adjacent blocks 10 to which each log 18a is fixed, via the protrusion 24 protruding from the top surface of each block. It is stably fixed along the inclined surface 26 in a vertical line, and the inclined surface 26
An earth retaining structure made of strong log material 18a can be formed along the line.

Note that the T-shaped groove 20 on the lower bottom surface of the block and the T-shaped protrusion 24 on the upper surface of the block are not provided perpendicularly to each ridgeline 16 of the block, but are placed along each ridgeline, depending on the condition of the slope forming the earth retaining. 16 may be provided so as to be inclined at a predetermined angle close to a right angle. In addition, when the block 10 is used for the end portion of a retaining block, a T
Of course, it is possible to insert and fix the end portion of the log 18a into only one side of the lateral groove 20a of the letter-shaped groove, and leave it open without inserting anything into the other side. Furthermore, the block 10 of the present invention has each end of an earth retaining bar formed using not only a log 18a but also a square timber, a concrete bar, or a synthetic resin bar at a predetermined position on the slope 26. Needless to say, it can also be used to fix a value so that it does not change.

As described above, by forming an earth retainer using the block of the present invention, a strong earth retainer can be easily and quickly formed on a slope by using raw wood logs such as thinned wood without any processing. Compared to conventional earth retaining, the material cost for earth retaining can be significantly reduced and the labor required for forming earth retaining can be greatly reduced.

In addition, the block of the present invention has a concave groove cut across the lower bottom surface in the horizontal direction into which the end of the log is inserted. It can also be used as a block for connecting and fixing logs in the middle.

Furthermore, the concave groove on the bottom surface of the block is formed in a T-shape, and the protrusion on the top surface of the block that fixes the blocks is also formed in a T-shape. It is firmly fixed so that it does not move easily, and can form a strong earth retaining structure. In addition, the concave groove on the bottom of the block serves as a fixing groove for logs piled up along the slope, a fixing groove for logs buried in the slope to fix the block to the slope, and a groove for fixing logs buried in the slope to fix the block to the slope. The block itself has been designed rationally and without waste, such as the groove that fits into the protrusion on the top of the block that fixes it.
It has a simple structure and is easy to form.

Although various preferred embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the embodiments described above, and many modifications may be made without departing from the spirit of the invention. Of course you can get it.
