Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a prefabricated channel-type fence culvert for constructing irrigation channels and drainage channels.

[Conventional technology]

Conventionally, as shown in Figure 6, for waterways such as simple sewage, irrigation channels, and small rivers, piles 1
1. Those that are constructed as earth retainers by assembling beams 12, boards 13, and capstones 14, and those that are constructed by setting frames 21 and panels 22 as shown in Figure 7 are generally used. In all of these cases, when setting the boards or panels, it is necessary to separately brace the boards or panels with wood or other material to prevent the boards or panels from falling off.

FIG. 8 shows an example of this, in which a peck bar 30 made of square timber or the like is supported by an external mound, etc. to prevent the panel 22 from falling to the outside, which eliminates the problem of requiring too much work. It was hot. In addition, most of the bottom plates were weak, and even after the frame and panels had been temporarily set, the panels would sometimes fall off during work, making assembly difficult.

[Problem that the invention attempts to solve]

It is an object of the present invention to solve these conventional problems and provide an assembly waterway having a structure that allows quick and stable assembly on site.

[Means for solving problems]

The present invention is comprised of U-shaped frames installed at required intervals along the length of a waterway, and panels set between the installed U-shaped frames with their ends supported. In the assembly channel, a tapered protrusion is formed on the panel support surface of the frame, and an outwardly upward hole is formed in the protrusion for attaching a connecting pin, and the tapered protrusion is formed on the panel in contact with the frame. The assembly water channel is characterized in that a recess is formed to complement the protrusion, and an inwardly downward hole for inserting the connecting pin is formed in the recess.

〔Example〕

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

FIG. 2 is a perspective view of the main parts of the U-shaped frame 1 according to the present invention, and the panel support portion 1a of the frame 1 has tapered protrusions 1b protruding from the panel support portion 1a corresponding to the number of panels. An upwardly directed hole 1c is formed in each case.

FIG. 3 is a perspective view of the panel to be set between the frames 1 as seen from the back side, and the connecting portion with the frame 1 is provided with a recess 2a into which the protrusion 1b fits, and there is a downward hole therein. 2b is formed.

Figure 4 shows the lower part of the panel.
It has the same structure as the upper and middle panels 2 except that it has cut portions 3c at both lower corners.

Figure 1 shows a state in which an assembled waterway is being constructed using the above-mentioned frame 1 and panels 2 and 3. Before assembling panels 2 and 3 to frame 1, frame 1 is
A connecting pin 4 with tapered ends is inserted into the side hole 1c as shown in FIG. 5, and the panels 2, 3 is set. Once the panels have been set between frames 1, a series of waterways can be constructed by installing the frames of the next span and setting the panels.

By using the connecting pin 4 in this way,
Even if the panel surface is inclined outward, it will not fall outward, and the span of the frame will be accurately positioned.

[Effect of idea]

As described above, the present invention provides the following effects.

(1) By using connecting pins, on-site assembly can be done quickly, and panels can be completely prevented from falling off, and there is no need for any parts or work such as poking rods, which are required in the past. .

(2) Since the frame and panel assembled using connecting pins are completely integrated, the whole is continuous and stable, therefore workability is good, and it is economical in terms of construction time and cost. You can expect good results.

[Brief explanation of the drawing]

Figure 1 is a perspective view showing the construction status of the assembled waterway according to the present invention, Figure 2 is a perspective view of the main parts of the frame, Figures 3 and 4 are perspective views of the panel, and Figure 5 is the connection of the frame and panel. 6 to 8 are perspective views showing examples of conventional assembled waterways.

Claims (1)

[Claims for Utility Model Registration] U-shaped frames installed at required intervals along the longitudinal direction of a waterway, and panels set between the installed U-shaped frames with their ends supported. In the assembly waterway configured with the frame, a tapered protrusion is formed on the panel support surface of the frame, and an outward upward hole is formed in the protrusion for attaching a connecting pin, and a contact portion of the panel with the frame is formed in the protrusion. An assembly waterway characterized in that a concave portion complementary to the tapered protrusion is formed in the concave portion, and an inward downward hole for inserting the connecting pin is formed in the concave portion.
