DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled U-shaped groove.

[0002]

2. Description of the Related Art Conventionally, a U-shaped groove made of concrete has been generally used. Concrete U-shaped grooves have advantages such as good weather resistance and good stability, but also have disadvantages such as heavy weight, poor workability, and difficulty in transportation. In order to solve this drawback, plastic U-shaped grooves have recently been used. However, they have a large volume and are expensive to store and transport. There are also drawbacks such as large expansion and contraction due to large thermal expansion and freezing due to light weight.

[0003]

It is an object of the present invention to provide an assembled U-shaped groove having weather resistance.

[0004]

Means for Solving the Problems Using a rigid thin plate such as a galvanized steel plate, a long member having an L-shaped cross section is formed. A plurality of L-shaped objects are combined in parallel to form a long, semi-cylindrical body that opens upward. Using a rigid material such as an angle material orthogonal to the long material, the long materials arranged in parallel are connected and reinforced at the same time to form an assembling U-shaped groove.

[0005]

[Function] Since it is formed of a rigid thin plate such as a galvanized steel sheet, the strength is large, and the strength is light and the workability is good. Each of the long materials can be brought to the site and can be assembled on site, so that it can be conveniently stacked during transportation and storage. A reinforcing frame is provided in contact with the outer cross-sectional surface of the synthesized semi-cylindrical body so as to have overall strength. In the case of light weight, the U-shaped groove may be lifted due to frost heave on the ground, but frost heave can be prevented by protruding the floating prevention tool to the side.

[0006] Although the present invention is an assembled U-shaped groove, its use is not limited to a drainage channel and the like, and can be widely used for wiring troughs and the like by providing a cover on the entire surface.
