Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trough support pile used when a trough for accommodating power cables, communication cables and the like is installed on the ground.

[0002]

2. Description of the Related Art When installing the above trough on the ground, a method is used in which the lower half of the trough support pile is buried in the ground and the trough is attached to the upper surface thereof. And as such a trough support pile, a prismatic concrete one is generally used.

[0003]

However, in such a conventional concrete trough support pile, the size of the trough that can be supported is determined because the trough mounting portion is only the upper surface, and the trough size is small. It is necessary to prepare trough support piles with different standards for each different type. For this reason, not only the manufacturing cost becomes high, but also inventory management is troublesome. The present invention has been made in order to solve such a conventional problem, and is made to provide a trough support pile that can be commonly used for troughs of various sizes.

[0004]

The present invention is characterized in that a support pile main body having upper and lower end surfaces formed on trough mounting portions has an inverted trapezoidal outer shape and a trapezoidal outer side shape. It is a thing.

[0005]

[Function] The trough support pile constructed as described above is installed by burying one of the trough mounting portions formed on the upper and lower end surfaces of the support pile main body to the required height from the ground surface and burying it in the ground. However, installing the trough at the trough mounting portion is the same as the conventional one. However, according to the present invention, since the front outer shape of the supporting pile body is an inverted trapezoidal shape, one of the trough mounting portions formed on the upper and lower end surfaces of the supporting pile body has a wide width and the other has a narrow width. Therefore, by using a wide trough mounting part for large troughs and a narrow trough mounting part for small troughs, it is possible to handle troughs of various sizes with one type of trough support pile. Is something that can be done. In addition, the outside shape of the side of the support pile is trapezoidal, which is the reverse of the inverted trapezoidal outside shape. Therefore, there is no danger of getting out of the ground.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to FIGS. In these figures, 1 is a pair of side plate portions 2, 2
A support pile body made of a plastic material such as FRP resin or high-density foamed polyethylene resin, which is formed by stretching the upper plate portion 3 and the lower plate portion 4 formed on the trough attachment portions 3a, 4a between the upper and lower ends of the is there. The supporting pile main body 1 has side plates 2 and 2 each having a trapezoidal shape in which the width of the upper edge is shorter than the width of the lower edge, and the side surface has a trapezoidal shape, and is stretched between the upper ends of the side plates 2 and 2. The plate portion 3 is wider than the lower plate portion 4 stretched between the lower ends, and the front outer shape is an inverted trapezoidal shape. Therefore, the outer shape of one side is a trapezoidal shape with a downward spread regardless of whether the top and bottom are taken up or down, and the support pile main body 1 can be prevented from slipping out of the ground. Further, by installing the wide upper plate portion 3 as the trough mounting portion, it is possible to deal with a large trough 21 as shown in FIGS. 1, 2 and 3, and the narrow lower plate portion 4 is used. By installing as a mounting portion, it is possible to support a small trough 22 as shown in FIG.

Reference numeral 5 designates a stabilizer plate which also serves as a reinforcing plate stretched over the intermediate portion of the side plate portions 2 and 2 of the support pile body 1 at a required interval.
6 is a reinforcing plate stretched between intermediate portions of the stabilizers 5 in the front-rear direction, and 7 and 7 are wing plate-shaped portions extending outside the side plate portions 2 and 2 to enhance stability when installed on a soft ground. The side wall portions 2 and 2 to which the auxiliary stabilizer 8 for installation is attached are window holes provided between the window holes 7 and 7, and the rectangular tube portion 9 also serving as a stabilizer plate through which the auxiliary stabilizer 8 can be inserted is provided. The side plate portions 2 and 2 are provided integrally with each other, and the front plate portion 10 of the square tube portion 9 is provided with a screw mounting hole 11 for inserting a screw for fixing the auxiliary stabilizing plate 8.

With such a structure, when laying a large-sized trough 21 having a wide width, the structure shown in FIGS. 1, 2 and 3 is used.
As shown in FIG.
The upper plate portion 3 having the above-mentioned structure is exposed by a required height from the ground surface and then embedded and installed in the ground, and the connecting portion of the trough 21 is attached to the trough attaching portion 3a by means such as screwing. .

Further, when laying a small trough 22 having a narrow width, as shown in FIG. 4, the upper and lower sides of the supporting pile main body 1 are reversed and the lower plate portion 4 having the narrow trough mounting portion 4a is formed. The desired height is exposed from the surface and the device is installed by embedding it in the ground, and the connecting portion of the trough 22 is attached to the trough attaching portion 4a by means such as screwing.

In addition, the supporting pile main body 1 has side plates 2 and 2 having a trapezoidal shape in which the width of the upper edge is shorter than the width of the lower edge, and the outer side surface has a trapezoidal shape. Since the upper plate portion 3 stretched between the two is narrower than the lower plate portion 4 stretched between the lower ends, and the outer shape of the front is an inverted trapezoidal shape, the support pile body 1 can be placed upside down in the ground. Since one of the outer shapes is trapezoidal, there is no danger of slipping out of the ground.

Further, the support pile body 1 is provided with a pair of side plate portions 2, 2
If it is made of a plastic material in which the upper plate part 3 and the lower plate part 4 are stretched between the upper and lower parts of the above, it is lightweight and easy to handle, and does not require much labor for transportation to the construction site and installation work. It is a thing. Further, when the support pile main body 1 is buried in the ground, earth and sand enter the support pile main body 1 and a stabilizer plate stretched between the side plate portions 2 of the support pile main body 1 at a required interval. Since 5 comes into contact with this earth and sand, it is possible to prevent slipping out and inclination from the ground regardless of the weight.

[0012]

As is apparent from the above description, in the present invention, since the outer shape of the front of the support pile body is an inverted trapezoidal shape, the trough mounting formed on the upper and lower end surfaces of the support pile body. Since one side has a wide width and the other has a narrow width, the size can be significantly increased by using a wide trough mounting part for large troughs and a narrow trough mounting part for small troughs. It is possible to deal with different troughs with a kind of trough support pile. In addition, since the outside shape of the side of the main pile is trapezoidal, which is the reverse of the inverted trapezoidal outside shape, even if the top and bottom are turned upside down, one of them will have a trapezoidal shape in the ground. There is no danger of getting out of it. Therefore, the present invention is of great practical value as a solution to the conventional problems.
