Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an earth retaining fence material that can be suitably used for earth retaining construction using thinned wood.

[Prior Art] In recent years, with the increase in land development, the demand for earth retaining construction has rapidly increased. Conventionally, gabions have been generally used for such earth retaining work, and the gabions were installed by filling them with chestnut stones, gravel, earth and sand, etc. It has become extremely expensive and difficult to obtain. For this reason, there are an increasing number of cases in which earth and sand from the site are used as is, but simply filling the gabions with earth and sand causes the earth and sand to flow out rapidly, making it impossible to achieve an effective earth retention effect.

In addition, in recent years, there has been a strong demand for the effective use of thinned wood for forest conservation and forestry promotion in the above-mentioned earth retaining works, etc., and in addition, when carrying out forest road projects, mountain conservation projects, general roads and land development, etc. However, there is a need to use organic materials such as the thinned wood mentioned above to promote greening and create a vibrant forest.

On the other hand, as an earth retaining method that can simultaneously make effective use of thinned wood and prevent earth and sand from flowing out, for example, as shown in Fig. A crossbar 2 facing in the width direction is arranged, and restraints 3 and crossbars 4 intersecting with the crossbar 2 are stacked alternately on top of the crossbar 2, and these restraints 3 and crossbars 4 are connected to each other by metal fittings 5. There is a log piling earth retaining structure in which the logs are fixed and the gaps are filled with earth, sand, gravel, etc., and as shown in Figure 6, a plurality of horizontal logs 8 are installed on the backs of piles 7 driven at regular intervals using iron wire. Many earth retaining methods are being implemented using thinned wood, such as log fencing, in which horizontal logs are piled up by tying them together with ropes, etc., and the backs of the horizontal logs are filled with earth and sand.

However, with this earth retaining method that uses only thinned wood, it is difficult to create sufficient topsoil and vegetation because the thinned wood rots quickly, taking several years. There was a risk of a disaster.

Therefore, as a result of intensive research, by combining thinned logs with a support frame made of metal wire,
Even when earth, sand, gravel, etc. are used as filler, it can be supported reliably and stably, and even if the rods rot, the earth retaining effect will not immediately disappear, and it will last for a long time. We developed an earth retaining fence that can maintain excellent earth retaining function (Utility Model Application No. 64-651).

However, such earth-retaining fences are usually installed in remote locations with poor footing, so it takes a lot of time and effort to pack and transport materials, especially support frames with three-dimensional shapes, and assemble them on site. It has the problems of requiring time and increasing costs. Therefore, in order to solve these problems,
It is necessary for the above-mentioned support frame to be able to package and transport a large number of items at the same time, and to be able to be easily assembled on site, and there is a need for further improvements in these respects.

[Problems to be solved by the invention] The problem of the invention is to make the supporting frame of the above-mentioned improved earth retaining fence easy to pack and transport, and to be able to assemble it on site easily and in a short time. It consists in composing.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides that the support frame for supporting the log is made up of a plurality of horizontal lines and vertical lines arranged at predetermined intervals, and that at least both ends of the horizontal lines are a front mesh provided with a connecting ring; and an intermediate frame bone line that is connected to a vertical line in the front mesh and that cooperates with the vertical line to form a frame that has an installation part for horizontally laying logs on the bottom side. and an end vertical bone line that is inserted into the ring at the end of the horizontal line in the front mesh, and serves as a substitute for the vertical line at the end of the front mesh, and also serves as a connecting bone line when connecting the support frames, An end frame bone line is connected to the end longitudinal bone line and cooperates with the longitudinal bone line to constitute a bone frame at the end of the support frame.

[Function] Since the support frame is divided into multiple stackable parts, by stacking and packing a large number of these parts, it is possible to transport a large number of fence materials to the site at the same time. The effort and expense required for packaging and transportation are reduced.

Furthermore, since the support frame is divided into parts that are assembled to some extent, assembly work on site is very easy by connecting these parts.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

As can be seen from the overall perspective view shown in Fig. 1 and the sectional view of the used state shown in Figs.
1, logs 12 for earth retention stacked horizontally inside the front surface of the support frame 11, and logs 13 for fixing arranged at the rear of the support frame 11.

As shown in FIG. 4, the support frame 11 includes a front mesh 15, an intermediate frame bone line 16, an end longitudinal bone line 17,
End frame bone line 18, upper and lower connecting horizontal bone lines 19, 2
0, and an auxiliary bone line 21 for supporting the log.

The front mesh 15 is made by welding together a plurality of horizontal lines 24 and vertical lines 25 arranged at predetermined intervals. An installation part 26 is formed for horizontally installing the earth retaining logs, and connecting rings 24 are provided at both ends of each horizontal line 24 and vertical line 25, respectively.
a, 24a and 25a, 25b are formed. The above-mentioned installation part 26 is an intermediate frame frame line 1 which will be described later.
The support frame 11 is formed so as not to bulge out below the bottom side of the support frame 11, thereby eliminating the need to dig a groove in the ground corresponding to the installation part 26 and facilitating the installation of the support frame 11. In addition, when welding the horizontal line 24 and the vertical line 25, at least one line may be formed with a recess into which the other line fits, at the intersection thereof.

The intermediate frame frame line 16 has an L-shape with its upper end bent slightly downward, and has coupling rings 16a and 16b at both ends thereof, and a fixing log at a position near the rear of the bottom. By connecting both ends of the ring 16c to both ends of the vertical line 25 in the upper end front screen 15, logs are attached to the front and rear ends of the bottom in cooperation with the vertical line 25. It constitutes a substantially triangular bone frame in which installation parts 26 and 27 for use are aligned. The intermediate frame bone line 16 may have a shape other than the above as long as it can cooperate with the vertical line 25 to form a closed bone frame.

Further, the end vertical rib lines 17 are inserted into the rings 24a at the ends of the respective horizontal lines 24 in the front mesh 15, thereby serving as a substitute for the vertical lines at the ends of the front mesh 15, and at the same time, are inserted into the rings 24a at the ends of the horizontal wires 24 in the front mesh 15. , 11 (see Fig. 1).
A connecting ring 17a is formed at the upper end of 7, and a leg 29 is formed at the lower end thereof to be buried in the soil by extending the lower end straight downward. These legs 29 stabilize the position of the support frame 11 to facilitate construction when constructing the retaining fence (filling with earth and stones), and prevent the fence from sliding after the retaining fence is installed. to increase the earth retaining effect.

Further, the end frame bone line 18 is the intermediate frame bone line 1.
6, it is formed into an L-shape with the upper end bent slightly downward, has a connecting ring 18a at the upper end, and has an installation part 2 of a log 13 for fixing at the bottom.
Ring 18c that partitions 8 and transverse bone line 20 for lower connection
However, unlike the intermediate frame bone line 16, the end of the bottom extends straight forward, and the end vertical bone line 17 is inserted through the ring 18b. A ring 18d for use is formed. By being connected to the end longitudinal bone line 17, the end frame bone line 18 is connected to the end longitudinal bone line 1.
7 to form a triangular bone frame at the end of the support frame 11. In addition, this end frame bone line 1
8 may have a shape other than the shape described above, as in the case of the intermediate frame bone line 16 described above.

The upper and lower connecting horizontal bone lines 19 and 20 are connected to the front mesh 15
It connects the vertical line 25 and the intermediate frame bone line 16, and the end vertical bone line 1 and the end frame bone line 18,
The upper connecting horizontal bone line 19 is connected to the upper ring 2 of the vertical line 25.
5a, an upper ring 16a of the intermediate frame bone line 16, and an upper ring 17a of the end longitudinal bone line 17 and the end frame bone line 1.
A ring 25 is inserted through the upper ring 18a of 8, and a lower connecting transverse bone line 20 is formed at the lower part of each line.
b, 16b, and 18b. The ends of the connecting horizontal bone lines 19 and 20 inserted through these rings may be bent as appropriate and locked to the bone frame at the end of the support frame 11.

Furthermore, the auxiliary bone line 21 for supporting the log has an inverted J shape with the upper end bent downward, and the lower end thereof is provided with a connecting ring 21a, and the lower connecting horizontal bone line 21 is attached to the lower end of the auxiliary bone line 21. By passing the wire 20 through, it is attached at an appropriate position between the bone frames. This auxiliary bone line 21 is used to hold the logs 12 so as not to separate from the inclined front net 15 when the logs 12 for earth retention are stacked and filled with earth and stones behind them. The portion 21b is removably connected to the upper connecting horizontal bone line 19, and when stacking the logs 12, the bent portion 21
b is removed from the upper connecting transverse bone line 19 and the auxiliary bone line 21 is tilted backward so that it does not interfere with the stacking. The portion 21b is locked to the upper connecting transverse bone line 19. Note that the above-mentioned stacking of logs and filling with soil and stones are usually performed in multiple steps.

The logs 12 for retaining the earth are fitted at the lowest level into the installation part 26 formed at the lower end of the vertical line 25 in the front screen 15, while the logs 13 for fixing are Middle frame bone line 1
6 and the end bone frame line 18 are installed on installation portions 27 and 28 formed at the bottom rear end portions.

Note that between the intermediate position of the vertical line 25 in the support frame 11 and the intermediate frame bone line 16, and between the end vertical bone line 17
A reinforcing bone made of wire rope or the like can be appropriately stretched between the intermediate position and the end frame bone line 18.

In the earth retaining fence having the above configuration, the support frame 11 is the fourth
After being disassembled into the parts shown in the figure and transported to the site, they are assembled as shown in Figure 1.
Logs are piled up and filled with earth and stones, and the logs are stacked in one or more layers at a predetermined location.

At this time, since the support frame 11 is divided into a plurality of stackable parts, by stacking and packing a large number of these parts, it is possible to transport a large number of fence materials to the site at the same time. This reduces the time and expense involved in packaging and transportation.

Further, the support frame 11 is divided into parts that are assembled to some extent, and each part is
Horizontal bone lines 19 for connecting the upper and lower sides to the rings formed therein,
20 can be connected by simply inserting them, the assembly work on site is very simple. Furthermore, when connecting multiple support frames 11, 11 as shown in FIG. In order to do this, it is only necessary to overlap the rings 24a at the ends of the horizontal wires 24 in these support frames and insert the end vertical ribs 17 therethrough. Therefore, it is very easy to install a long earth retaining fence. be.

In the earth retaining fence thus installed, the logs gradually rot due to long-term use, but the support frame 1
Since the front surface of the log 1 is a mesh surface, the rotten log 12 does not immediately collapse and fall off, and is held in place by the mesh surface. Therefore, the earth retaining function will be maintained over a long period of time, during which time sufficient topsoil construction and vegetation will progress.

Note that the most suitable inclination angle of the front mesh 15 of the support frame 11 is generally about 73 degrees, and
Logs 12 and 13 usually have a diameter of about 10 mm at the end.
Logs of about cm are suitable, but these front nets are 15 cm long.
The inclination angle, the thickness of the log, the cross-sectional shape, etc. can be determined as appropriate depending on the installation conditions of the earth retaining fence, such as the size of the earth retaining fence and the soil quality of the site.

Further, in the above embodiment, the earth retaining fence is explained in which the frame has a triangular shape, but the frame is not necessarily limited to this shape, and may be formed in any other shape, such as a trapezoid or a square shape. You can also.

[Effect of the invention] According to the invention having the above configuration, the support frame is divided into a plurality of parts that can be stacked one on top of the other. Materials can be transported to the site, and the labor and expense involved in packaging and transport can be reduced.

Furthermore, since the support frame is divided into parts that are assembled to some extent, assembly work on site is extremely easy.
