Description

[Detailed description of the invention] This invention relates to a U-shaped groove-shaped trough for arranging high-voltage and low-voltage distribution lines buried under sidewalks, etc. The bottom plate of a male member with an inverted L-shaped cross section is This is a combination type U-shaped groove type trough in which a bottom plate of a female member having an L-shaped cross section is stacked on top, and a U-shaped groove is formed together with the side plates of both members.

When transporting to the installation site, the male and female members can be transported separately, and the unevenness of the female member can be fitted into the unevenness of the male member to create a U-shaped structure without using bolts. It is a U-shaped groove-shaped trough with a combination bed that forms a groove, and since it is separated into two parts to be transported to the installation site, it is light and not bulky, making it easy to transport.
The purpose is to allow quick assembly by simply overlapping the male and female bottom plates and fitting them together, and to save space when storing them before construction.

Therefore, several separate walls are protruded inside the side of the female member to house the high voltage power distribution cable separately, and the low voltage power distribution cable is rolled on the bottom surface, and a notch is provided on the side plate of the male member. A hole is provided so that, if necessary, the high voltage distribution line on the separate wall of the female member can be drawn out through the notch hole in the side plate of the male member.

The structure of this invention will be explained with reference to the drawings. A raised part 4 is horizontally protruded across the front and rear ends of the side plate 2 slightly above the inner part of the side plate 2 of the male member 1 having an inverted L-shaped cross section and made of reinforced concrete and has a tapered surface on the lower side. 5 to form a horizontal groove 6 between the side plate 2 and the bottom plate 3. A notch hole 7 is provided in the center of the side plate 2, a raised portion 8 is provided at the outer end of the tip of the bottom plate 3, and a tapered surface 1 is provided between the top surface 9 of the bottom plate 3 and the top surface 9 of the bottom plate 3.
Set 0. This tapered surface 10 is parallel to the tapered surface 5 described above. Recessed holes 11, 11 are bored at both the front and rear ends of the upper surface 9 of the bottom plate 3, and at the end side edges of the recessed holes 11, 11, holes for connecting the central plate part, which has both sides of a planar U-shaped iron plate embedded in concrete, are formed. iron wall 12, 12
are provided and bolted to the iron wall 12 at the end side edge of the recessed hole 11 of the bottom plate 3 of the male member 1 arranged next to each other through bolt holes drilled in the iron walls 12, 12.

The female member 13 is made up of a side plate 14 and a bottom plate 15 with an L-shaped cross section. On the inside of the side plate 14, several stages of separate walls 16, 16, 16 are provided protruding downward from the back, and the side plate 14 and the bottom plate 15 are connected to each other. A tapered surface 10 of the raised portion 8 of the male member 1 is attached to the outer corner of the adjacent portion.
A tapered surface 17 is provided at an angle that matches the bottom plate 1.
5 to the raised part 4 of the side plate 2 of the male member 1.
A tapered surface 18 with an angle matching the tapered surface 5 of
It has been removed. Also, separate walls 16, 16, 1
A lid 19 is provided, which intersects the tip of the lid 1 at right angles to the tip of the lid 1, and a portion that curves at the upper end and becomes horizontal extends along the uppermost separate wall 16 and is bolted.
One end of the front and rear sides of the trough 9 is stepped and slightly larger, and has an extension 19' projecting outwardly so as to partially cover the lid of the separate wall of the adjacent trough. Furthermore, a side plate 14 on the inner surface of the female member 13
A tapered surface 20 is provided in the central portion excluding both sides of the intersection between the bottom plate 15 and the bottom plate 15 . Therefore, the center portion of the lower end of the lid 19 is shortened only at the portion where the tapered surface 20 is located, and the lower end is in close contact with the center portion of the tapered surface 20. Also, the male member 1 and the female member 1
The upper ends of each of the side walls 2 and 14 of 3 are formed with a side edge 21 that protrudes slightly outward, and an inner edge 23 that is lower than the side edge 21 and covered with rubber 22. Therefore, in order to combine the male member 1 and the female member 13, the bottom plate 15 of the female member 13 is placed on the bottom plate 3 of the male member 1.
When the tips of the bottom plate 15 are stacked and slid diagonally from above toward the side plate 2 of the male member 1, the outer edge of the tip of the bottom plate 15 fits into the groove 6 on the inner lower part of the side plate 2 of the male member 1. In other words, the tapered surface 18 at the outer edge of the tip is in close contact with the tapered surface 5 of the side plate 2 of the male member 1, and the tapered surface 17 at the outer corner of the intersection of the side plate 14 and the bottom plate 15 is in close contact with the bottom plate 3 of the male member 1. It can be fitted tightly into the tapered surface 10 of the protruding portion 8 at the tip. Both members 1 and 13 have bottom plates 3 and 15 stacked on top of each other and side plates 2 and 14 facing each other. bolt 25
The eye bolts are screwed into these bolt holes to connect the male member 1 and female member 13.
It was also designed so that it could be lifted up. Although there is no particular drainage facility for rainwater, there is no particular problem because it flows from between the male member 1 and the adjacent male member 1 connected. Also, the high voltage distribution cable 26 supported by the separate wall 16
Since the separate wall 16 is recessed and the sides are covered by the lid 19, there is no chance of it falling off other than by human action.

As described above, this invention has both bottom plates 3, 15 of the male member 1 having an inverted L-shaped cross section and the female member 13 having an L-shaped cross section.
If you stack and slide it from the side diagonal upper mold, the male mold member 1
The bottom plate 15 of the female member 13 on the bottom plate 3 is tightly fitted and has a fit-in structure that cannot be easily removed by force in both the vertical and horizontal directions. Therefore, the male members 1 and the female members 13 are transported separately to the underground cable installation site, and the plurality of male members 1 are connected to each other by bolting the iron walls 12 of the recessed holes 11 on both sides of the bottom plate 3. Next, a plurality of female members 13 are fitted into each male member 1 and assembled as described above, the high voltage distribution cable 26 is dividedly supported on the separate wall 16, and the low voltage distribution cable 27 is placed on the bottom plate 15. , respectively. The high-voltage power distribution cable 26 on the separate wall 16 can be extended to the outside through the notch hole 7 in the side plate 2, if necessary.

Therefore, if this invention is used for underground distribution cables laid in places where relatively deep digging is not required, such as under sidewalks, instead of a single U-shaped trough,
Since it is divided into two parts, a male type and a female type, it does not take up much space to store and is easy to transport to the installation site. In addition, the male and female members can be easily assembled and combined, and once the male members are connected to each other, the bottom plate of the female member can be placed horizontally on the bottom plate of the male member. They can be completely assembled by simply sliding them on top of each other from above, and can be completed by placing a top plate on top of them without any need for bolts, etc., which has the advantage of being separated into two parts for storage and transportation. It has the advantage of being easy to install and assemble.

Moreover, as mentioned above, the female member has each tapered surface,
Since it is fitted from the horizontally upper side in line with each tapered surface of the male member, once assembled, it will not come off even if force is applied from both the upper and lower sides of the U-shaped trough. In addition, the high voltage distribution lines are housed in separate walls according to the type of high voltage distribution line, direction, etc., and are held without fear of falling onto the bottom plate.

This invention has various effects as mentioned above.
