Description

[Detailed Description of the Invention] The present invention relates to a slope protection frame with excellent workability and strength.

Traditionally, there have been various types of slope protection frames, and those that are superior in strength are generally heavy and cumbersome to install, and have poor workability.
Those that pursue good workability have a simple structure, but have the drawback of being weak in strength.

Therefore, the inventor worked hard to eliminate the above-mentioned drawbacks.
As a result of repeated research, the present invention was developed by forming a top surface at the corner portions of both legs extending at a substantially right angle, providing a protrusion approximately in the center of the top surface, and forming the top surface and the top surface at the lower ends of both legs. A large number of slope blocks with locking parts that lock at about 1/2 of the protrusions are installed horizontally on the slope.
At the upper stage of this stage, the locking parts at the lower ends of both legs of the same legal frame block are secured to about 1/2 of the top surface and protrusion of the lower stage of the legal frame block, and these steps are repeated in order to lay the blocks. However, by connecting the corner portions of both legs and the lower end portions of both legs with a connecting line,
It has superior workability and strength, and solves the above-mentioned drawbacks.
That purpose has been achieved.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings.

In addition, a lower edge sap block C ₂ is attached to the lower edge of the protective frame.
The end of the upper and horizontal sap material block D and the end of the leg 1 of the slope block A are tensioned and connected by the connection line 14 (see Fig. 1), and in this way, the slope A protective frame will be constructed.

It is also possible to fill the slope blocks A, A, . . . of the slope protection frame constructed in this way with cracked stones, or to plant appropriate plants on the slope a inside these frames.

Next, the effects will be explained.

In the present invention, both legs 1 extending at a substantially right angle,
A top surface 2 is formed at a corner of the top surface 2, a protrusion 3 is provided approximately at the center of the top surface 2, and approximately 1/2 of the top surface 2 and the protrusion 3 are provided at the lower ends of both legs 1, 1. The slope block A, which has the locking parts 4, 4 that lock in place, is placed on the slope a.
A large number of locking portions 4 at the lower ends of both leg portions 1, 1 of the same legal frame block A are provided in this step.
4 to the top surface 2 and about 1/2 of the protrusion 3 of the lower deck A, and repeat these steps one after another until the corners of both legs 1, 1 and both legs are secured. By connecting the lower end portions of 1 and 1 with the connecting line 14, there is an effect that both workability and strength are excellent.

To explain the operation and effect in detail, the laying construction can be carried out sequentially, or about 1/1/2 of the engaging part 4, top surface 2, and protrusion 3.
The construction is extremely simple, as it only involves engaging two points and connecting these points with the connecting line 14, and the legal frame block A itself is a relatively light block that is simply L-shaped. , it is possible to provide a slope protection frame that is easy to handle such as transportation and carrying, and has excellent workability. In particular, by laying the legal frame blocks A one after another, the structure becomes a trough stacked shape or a straight stacked shape, and the force of both legs 1, 1 of the legal frame block A rigidly connected to the L shape is applied to the lower legal frame block A. The structure is supported by the top surface 2 of the structure, and by connecting this point, the structure is integrated into a chain-like truss structure, which is strong and has an even stress distribution. Because of this, it adapts well to the slope surface A, making it difficult to slip down and allowing for stable installation.

In addition, the slope block A, end material block B, lower sap material block C, _lower end sap material block C, ₂ , upper and horizontal sap material block D, etc. are made of special concrete such as fiber-reinforced concrete, and have an inverted T-shaped cross section. If this is done, the weight can be further reduced, workability is doubled, strength is increased, and corrosion resistance is improved, among other effects.
