Description

[Detailed description of the invention] <<Detailed description of the invention>> The present invention relates to a slope frame used as a slope protection vegetation work.

In addition, in this specification, the term "legal frame" refers to the construction of soil on the slope surface formed during housing land construction or road development, as well as the construction of additional soil within the legal framework covered by walls, etc. It is used as a so-called slope protection vegetation work that stabilizes the soil on the slope and scatters plant seeds or plants seedlings.

《Prior art》 This type of legal framework is as shown in Figure 6.
It comprises a ring-shaped member 1 whose ends are connected by a connecting fitting 1a, and a cross-shaped member 2 formed by combining two L-shaped members 2a and 2b at their corner parts,
The legal frame of the ring-shaped member 1 is set by the cross-shaped member 2 by approximately 4
The area is divided into equal parts, and soil is added to each frame 5a for vegetation.

Both ends of the L-shaped members 2a, 2b are fixed to the inner wall of the ring-shaped member 1 by connecting members 3, and the intersecting portions of the L-shaped members 2a, 2b are connected by anchors 4 or the like. In addition, the ring-shaped member 1 and the cross-shaped member 2 are formed of a metal mesh of the required width, usually a clip wire mesh made of iron wire specified in JIS-G3553. The construction method that uses a seed sill is generally called the mesh ring construction method).

Figures 7 and 8 show examples of how the slope frame 5 is used. The figure is a side sectional view of the slope.

A large number of slope frames 5 are successively arranged on a slope 6 and are fixed to the slope 6 by anchors 4 and sub-anchors 7. The anchor 4 is driven into the intersection of the L-shaped members 2a and 2b, and the sub-anchor 7 is driven into the continuous part of the ring-shaped member 1. In this way, additional soil is applied and vegetation is applied to such an extent that the legal frame 5 is almost hidden.

Compared to the case where the slope is made of concrete or the like, such a slope 5 not only allows construction to be adapted to the topography, but also improves the water permeability and air permeability of the top soil. It has the advantage that the roots of the plant can spread and become stable through the mesh without having to divide them.

<<Problems to be solved by the invention>> By the way, a large number of the above-mentioned legal frames 5 are often used at the same time, and although they vary in size, for example, the outer diameter of the ring-shaped member 1 is about 1 meter or more. There is also. For this reason, generally, the cross-shaped member 2 is separated from the ring-shaped member 1, and a large number of each are stacked and transported to the site.

However, there is a limit to the number of items that can be transported at one time, and this poses a problem in that the items cannot be transported efficiently. In addition, on-site assembly work is usually very troublesome because it must be carried out on a bank or other sloping site with poor footing.

Therefore, in addition to the advantages of the above-mentioned legal framework, the present invention provides:
The purpose is to provide a legal framework that can greatly increase the amount of transportation per time and reduce the number of on-site assembly work.

<Means for Solving the Problems> In other words, the civil engineering work frame of the present invention constitutes a unit protective member formed on a net-like wall surface by arranging straight metal wires vertically and horizontally. Both ends of the metal wires arranged in the direction are made into hook-like curved parts to form insertion locking parts, and a hinge pin is inserted into the insertion locking part on one side, thereby forming the unit protection members into a substantially dogleg shape. By connecting the slope protection materials to form a slope protection material, and inserting a hinge pin into the hook-shaped curved portion on the other side, the slope protection materials are connected to each other to form a slope frame. It is characterized by forming an engaging bent part.

<<Operation>> By connecting a plurality of unit protection members to form a slope protection material and stacking a large number of these in sequence, it becomes possible to bundle a large number of unit protection members without increasing the bulk. Further, by arranging the slope protection materials to face each other, a substantially rhombic slope frame is formed.

<<Example>> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing a state in which slope protection materials to which the present invention is applied are arranged facing each other, and FIG. 2 is a schematic perspective view showing a state in which a slope frame is formed by the slope protection materials. In these figures, the slope protection material has a unit protection member 12 consisting of wall surfaces 11a and 11b that can be formed into a substantially dogleg shape.
The slope frame 13 can be constructed by connecting a plurality of slope protection materials formed by connecting two slope protection materials, and by arranging other slope protection materials formed in the same manner to face each other.

The unit protection member 12 has a wall surface 11a and a wall surface 11b connected to each other via a hinge pin 14, and can be bent into a substantially dogleg shape by the hinge pin 14. The wall surfaces 11a and 11b are formed by arranging straight metal wires in the vertical and horizontal directions to form a mesh, for example, a crimp wire mesh made of iron wire specified in JIS-G3553 is used. In addition, the wall surfaces 11a and 11b are formed by forming metal wires into a continuous S-shape.
There is no problem even if the character-shaped member is covered with a net made of synthetic resin or the like to form a net shape.

The lower ends of the walls 11a and 11b have metal wires 15 arranged in the vertical direction protruding from the lower ends, making it easy to lock the wires 15 when laying on a slope.

Further, both ends of the hinge pin 14 are connected to the engaging bent portion 1.
4a and 14b are formed, and the unit protection member 12
hinge pin 1 against walls 11a and 11b of
4 to prevent it from falling out.

In addition, the width of the unit protection member 12 (height when installed)
The length when bent into a dogleg shape may be set appropriately depending on the need. For example, the width is set to 10 to 15 cm, and the
The length of each b is set to 3.5 to 4 cm, and the distance between both ends is 50 cm when bent into a substantially doglegged shape.

Further, the hinge 14 can be made of a metal wire or the like, and the end portion of the metal wire 16 arranged in the horizontal direction constituting the net shape of the wall surfaces 11a, 11b is bent into a hook shape 16a, and the end portion of the metal wire 16 is bent into a hook shape. It has a structure that allows it to be inserted and locked in a movable manner.

The unit protection member 12 formed in this manner is sequentially connected to other unit protection members 12 via the hinge pin 17, similar to the hinge pin 14. Then, a large number of connected unit protection members 12 are sequentially piled up and transported to the site. Further, when forming the legal frame 13, the substantially diamond-shaped legal frame 13 is formed by arranging the unit protection members 12 facing each other as shown in FIG. Further, both ends of the unit protection members 12 arranged opposite to each other are joined by anchors 18 or the like.

The tip of the anchor 18 is bent into a U-shape, and the unit protection members 12 can be joined to each other at this bent portion 18a. This anchor 18 also serves as a member for fixing the unit protection member 12 on the slope.
By using this, the efficiency of the joining work can be increased.

3 to 5 illustrate specific usage examples of the slope protection material. As shown in FIG. 4, the slope 19 has a section where the slope protection material is arranged, which is divided by a net-like partition member 20, and a plurality of the unit protection members 12 are connected to this partition 12.
Lay A, 12B...12G sequentially from the bottom end. In this case, the positions are adjusted so that the slope frame 13 is formed by the adjacent unit protection members 12, and the abutting portions of the adjacent unit protection members 12 are joined by the anchors 18 or the like, and the slope Fixed at 19. Further, the contact portion with the partition member 20 may be firmly joined using a connecting fitting 21 having a substantially L-shaped cross section, as shown in FIG. The connecting fitting 21 is provided with a plurality of opening windows 21a in order to obtain water permeability and air permeability, and bendable locking portions 22 are each formed by cutting and bending. Then, a stud-like locking pin (not shown) is passed through the mesh hole of the unit protection member 12 or the partition member 20, penetrated through the hole 22a of the locking part, and the locking member 22 is bent downward to join. It has a structure.

The slope 13 formed as described above and the slope 23 formed by the unit protection member 12 and the partition member 20 are covered with soil, soil piling, etc. to the extent that the slope protection material is almost hidden, as in the past. and vegetation. In addition, unit protection members 12A, 12B,...12
It is also possible to connect the Gs to each other by hinge pins 17, thereby making it unnecessary to connect them by anchors 18 on site.

Note that the slope frame of the present invention is not limited to the above-mentioned usage example, and the slope frame 13 may be formed by combining a plurality of slope protection materials formed by connecting unit protection members 12 in a dogleg shape. It goes without saying that various modifications can be made as long as they are used.

<<Effects of the invention>> As explained above, the present invention has all the advantages of conventional mesh-type slope protection materials, and also has a plurality of unit protection members connected. Since many pieces can be stacked one on top of the other and transported to the site without increasing the bulk, the amount transported at one time can be greatly increased compared to conventional ring-shaped members. In addition, when forming a slope frame by connecting a plurality of the slope protection members, it is only necessary to insert the hinge pin into the insertion locking part formed by the hook-shaped curved part formed at the end of the unit protection member. A separate assembly operation for forming the framework prior to laying on the surface can be eliminated.

In the present invention, the insertion locking portion of the hinge pin is formed by forming a curved portion at the end portion of the straight metal wire arranged in the transverse direction that constitutes the net-like wall surface of the unit protection member. The hinge pin is inserted and locked into a curved part made up of metal wires arranged laterally at certain points (six places in the above embodiment), and engaging bent parts are formed at both ends of the hinge pin. Therefore, the unit protective members can be assembled very reliably, and once assembled, they will not easily come off.
