Abstract

PURPOSE:To cut down on the cost price of a slope frame by connecting two or more frame bodies made of a rigid belt-like material, having large numbers of water-permeable holes piercing its surface and back sides, in series by using metal annuluses in such a way as to enable them to be freely folded. CONSTITUTION:Belt-like frame bodies 2 having water-permeable holes 1 and a rigidity are connected with one another in series in the longitudinal direction by using metal annuluses 3 in such a way as to enable them to be freely folded in order to form a slope frame. As the belt-like body, an expandible metal, a perforated steel plate, etc., having a width of 5-100cm, a length of 30-200cm, and a thickness of several mm.-5cm, are usually used.

Description

[Detailed description of the invention] The present invention relates to a legal frame material and a method of forming a legal frame.

Because Japan has a large area of mountain forests, civil engineering works such as roads, railways, and land reclamation often involve slope construction, and many excellent materials and construction methods have been developed for slope construction. has been done. However, in recent years, slope construction has become longer due to development in remote areas, and labor and transportation costs are high, so materials and construction methods that are lightweight, compact, and easy to transport and construct are required. It became so.

In response to these modern demands, the present invention aims to provide an inexpensive and highly effective method for forming a legal frame material and a legal frame.

Embodiments of the invention will be described in detail with reference to the drawings.

[Example 1] As shown in Fig. 1, a long band-like body (2) having many water passage holes (1) and having rigidity, such as expanded metal
) are arranged in series in the longitudinal direction with metal rings (3
), etc., so that the strips can be freely folded to a certain degree.

and firmly interlock to form a legal frame material.

It is convenient for connection to attach similar metal rings to the ends of the strip at both ends.

In addition to expanded metal, the strips used in this example include perforated steel plates, perforated plastic plates, perforated thin concrete plates, etc. that have water passage holes and are rigid enough to support earth and sand on slopes. use The width of the strip is usually 5 to 10,051 mm. Preferably 10-501. The length is usually 30 to 200 strokes, preferably 50 to 1001 strokes. The thickness is usually several layers to about 5z.

The bending rigidity may be increased by forming the vertical cross section of the band-like body into a corrugated shape or adding a lip.

As for the water passage hole, it is better to use a hole with good water permeability, or if it is too large, the earth and sand will be washed away.
It is preferable that the number is 1 or less and that it is attached to the entire surface of the strip. The number of connected belt-like east bodies is usually between two and ten.

It is usually necessary to leave a gap of 1 to several 1 between the strips for bending. There are no particular restrictions on the material or shape of the connector as long as it is strong and bendable, but it is convenient if it is annular because it can be driven through the anchor bottle.

Connectors can also be formed by connecting several metal rings in a chain, or in the case of concrete plates, by driving the ends of several bendable iron wires into a strip. .

[Example 2] As shown in Fig. 2, a large number of semi-cylindrical bodies (5) made of plastic or the like and having a U-shaped cross section and having large water holes (1) in the side plates (4) were placed at slight intervals. Then, while arranging them in series, strong plastic threads such as nylon-polyester are connected using a stringing machine to form a mesh 16) around the periphery as shown in Fig. 3 to form the frame material. .

The semi-cylindrical body used here usually has a length of 50 cIR to 100 cIR.
cI11. The width of the side plate is usually 5-2051mm. The width of the edge (7) is usually 1 to 33 mm.

Since the threads forming the outer mesh are not easily cut when bent at the connecting portion (6), it is preferable to use thick and strong threads of several thousand to 20,000 deniers.

The purpose of including the semi-cylindrical body is to ensure water permeability in the vertical direction of the completed legal frame material.

The material and shape are not limited to the examples.

Any material may be used as long as it is permeable to water in both the longitudinal and lateral directions. Furthermore, the method of forming the mesh around the two is not limited to the embodiment, and may be wrapped in a flat plastic net.

Since the girder frame material of the present invention is constructed in this way, when constructing it, the girder frame material of Example 1 is bent at the connecting part (8) as shown in FIG. A large number of them are joined together to form a polygon, and as shown in Fig. 5, a large number of them are stacked on the slope to form a slope frame, and appropriate anchor bins 19) are formed.
etc. to determine ll. In this case, it is advantageous to use anchor pins that simultaneously penetrate the metal rings of adjacent frame materials, as shown in FIG. 6, because fixing and joining of the frame materials can be accomplished at the same time.

In addition, the slope material of Example 2 was bent in a zigzag manner at the connecting portion (8) as shown in Fig. 7, and then lined up vertically on the slope as shown in Fig. 8 to form a slope. , use an anchor bottle or the like as appropriate for identification.

In addition, when used as a legal frame, the width of the legal frame material is usually 10~
20cI11, but using a wide band, the seventh
As shown in the figure, it can also be bent into a corrugated shape and used as a shag.

Since the slope material of the present invention is constructed in this manner and constructed in this manner, it has the following nine features.

■ It is lightweight and can be stored, transported, and delivered to the site as a plate, so storage fees and shipping costs are extremely low.

■ If you bend it and set it on the slope, the approximate shape will be completed, so the time and effort required for positioning and assembling on the slope can be greatly reduced, so the construction will be faster and the construction cost will be lower.

■ You can adjust the length and connection angle to some extent at the connection part, and you can also freely choose the bending angle.

It can adapt to the unevenness of the slope to some extent, making construction easy and stable.

■ Since the main body is made of a rigid body, such as a band or semi-cylindrical body, it can sufficiently support the soil within the legal framework.

Further, as shown in FIG. 9, it is also easy to construct a legal frame material with four strips, two each for long and short strips, and assemble them into a horizontally long rectangle. Since the effect of supporting earth and sand in a drawing frame with horizontal sides and short vertical sides is good, an excellent legal frame can be formed by configuring it in this way.

■ Water holes are formed in the main body.

Since water does not accumulate within the slope frame and the roots of plants become entangled with each other through the two water holes, it is possible to form a slope that is difficult to run off as a whole.

(2) In the case of Embodiment 2, water pipes are formed in the longitudinal direction of the two main bodies, so that water can be drained downward through one water pipe. It is ideal as a legal framework for slopes with a lot of spring water, areas with heavy rains, etc.
