Abstract

PROBLEM TO BE SOLVED: To prevent covering soil from sliding down at a low cost and create an environment suitable for creatures by connecting block bodies in which a pierced hole is provided between artificial stones arranged on the surface, through connecting hooks and laying them on the revetment surface. SOLUTION: A number of artificial stones 3 are arranged on the surface and a pierced hole 2 is provided between artificial stones 3 to form a circular or a polygonal block body 1 and connecting metallic hooks 4 divided into a plurality of pieces are buried in the outer periphery of the block body 1 at both ends The block bodies 1 made in such a way are arranged on a revetment surface and the connecting hooks 4 of adjacent block bodies are joined with U-shaped connecting metal tools to lay the block bodies. And soil is filled between respective block bodies and in the pierced hole 2. Mutual blocks can be rapidly and freely connected at an appropriate position within the reachable distance of the connecting metal tools. And the appearance and the weight per unit quantity are changeable by changing the arrangement of the block bodies 1 and hence, only one kind of mold for production is sufficient and the production cost and construction cost is low.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revetment block characterized in that blocks used for revetment on slopes of rivers, coasts, lakes and marshes can be easily connected to each other at any place. is there.

[0002]

2. Description of the Related Art For protection of slopes such as rivers, coasts, lakes and marshes, there are many methods of covering with concrete blocks. Regarding the connection of these blocks, a hook for connection is buried in a specific part of the block, Although a method of connecting the connecting hooks to each other by a connecting metal fitting is adopted, in this case, when the blocks are arranged, it is necessary to form a block in which the connecting hooks are adjacent to each other. Blocks could not be placed and connected in any direction, and joining the curves was a problem. Also,
In recent years, large-scale revetment blocks have been used, but with such large blocks, atypical blocks that match the curve are used, or large blocks are cut and gussets are provided to deal with the cast-in-place concrete. However, such a method is not only unfavorable for the landscape, but also leads to the destruction of the natural habitat environment of living things.

[0003]

From the above situation, even if the planar shape is an arbitrary shape such as a circular shape or a polygonal shape, the blocks can be freely connected and the curve construction is facilitated. It is required to develop a multi-natural landscape creation block that can create a space for methods and vegetation greening functions and create a living environment for living things.

[0004]

The present invention has been proposed to solve the above-mentioned problems, and its constitution is as follows.
A single or plural connecting hooks are provided at appropriate intervals from the periphery of the main body so that the main block having an arbitrary shape such as a circular shape or a polygonal shape can be easily connected at any place. The end of the hook is embedded inside the main body to form a single body, a large number of pseudo stones are formed integrally on the surface of the main body to create a landscape, and a space for vegetation greening function is created to create a living environment for living things. As shown in the figure, one or several through-holes that pass from the front surface to the back surface are provided between many pseudo stones provided on the front surface of the main body.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described with reference to the drawings.
The block of FIGS. 1 to 3 has a circular outer shape,
Reference numeral 1 is a main body of the block, 2 is a through hole provided in the center of the main body 1, and in this example, it is a triangle, but it may be circular or polygonal. A large number of pseudo stones 3 are provided on the surface of the main body 1 of the block. Four
Is a metal connecting hook provided on the outer periphery of the main body 1 at a constant interval and is divided into three pieces. Both ends thereof are embedded inside the main body 1.

The main body 1 is formed not only in a circular shape as shown in FIGS. 1 to 11, but also in a polygonal shape such as a hexagonal shape, an octagonal shape as shown in FIGS. 12 and 13, or an appropriate shape as shown in FIG.

When the main body 1 has a circular shape, the connecting hook 4 may have a single circular shape as shown in FIGS. 4 and 5, and in that case, the connecting hooks 4 project at appropriate intervals from the connecting hook 4. 5 is projected, and its end is embedded inside the main body 1. When the connecting hooks 4 are circular, they are two as shown in FIGS. 6 and 7,
It may be appropriately divided into three pieces as shown in FIG. 9 and four pieces as shown in FIGS. 10 and 11, and the end portions are embedded in the main body 1, respectively.

When the main body 1 is formed in a polygonal shape as shown in FIGS. 12 and 13, the connecting hooks 4 project on each side,
The end portion is embedded inside the main body 1. When the main body 1 is formed in an appropriate shape as shown in FIG. 14, the connecting hook 4 is formed in one circular shape, the projecting piece 5 is projected from an appropriate position, and the end portion thereof is placed inside the main body 1. Buried.

FIG. 15 shows a metal fitting 6 for connection, which has spiral portions 7 at both ends of a U-shaped rod, through which a strip 8 is inserted.
A nut 9 is screwed into the spiral portion 7.

Since the present invention has the above-mentioned structure, it is arranged as shown in FIG. 14 and FIGS. The band-shaped rod is inserted, the band plate 8 is fitted, and the nut 9 is screwed together, thereby repeating the connection. Then, the plant 10 is vegetated in the space between the blocks.

[0011]

According to the present invention, by arranging the connecting hooks 4 along the outer periphery of the block at a constant distance from the side surface of the main body 1 of the block, when the block is laid on the revetment surface, As long as the contact points of the connecting hooks 4 and 4 or the distance that the connecting hooks 4 and 4 reach through the connecting metal fittings 6, the connecting hooks 4 and 4 can be freely connected at an appropriate position, construction is extremely easy and quick. In addition to straight lines, any curved construction can be easily and firmly connected, and the connected blocks are highly flexible and fit well on the slope.

Further, the weight per unit can be changed by changing the arrangement of the blocks, and the soil formed in the space formed between the laid blocks and the through hole provided on the surface of the main body can be changed. It is filled with sand and gravel, and these places serve as a growth space for plants and a habitation space for living things, so that an environment suitable for living things can be created.

Further, by forming pseudo stones on the surface of the blocks, natural stones are arranged, and even blocks formed by one type of formwork can be arranged without orientation, so that various surface expressions can be obtained. Is created and various landscapes are created, the manufacturing cost of blocks can be reduced and the construction cost can be reduced, and it also prevents slipping of cover soil, and plants grow and cover revetment surfaces. It is effective in creating a natural environment.
