There is a hole in the side of the main body 100, and a plurality of through parts 300 in the form of a conduit 320 connecting the hole in the side of the main body 100 and the hole in the periphery of the hollow box 220 are formed. dog is formed

The penetrating portion 300 is formed to extend from the hollow box 220 while being bent in a predetermined direction along the longitudinal direction toward the side of the body portion 100. Specifically, the through portion 300 extends downward from the hollow portion 200 and a preset bent portion ( It may be formed so as to pass through the side of the main body 100 by passing through (not shown).

Here, the through part 300 may be a passage for allowing the electric wires or electric equipment to enter and exit the hollow box 220 from the outside.

Accordingly, the bent portion may be formed to have different angles between the inside and the outside.

For example, the bent portion may preferably have an obtuse bending angle, and the bent portion may be bent at a relatively gentle angle on the inside of the bent portion than on the outside.

On the other hand, the ground portion 400 is formed to be elongated in the vertical direction of the body portion 100, and a plurality of them are radially arranged around the hollow portion 200, and at least some of them may be formed to have different rigidity in the longitudinal direction. have.

The grounding unit 400 will be described in detail with reference to FIG. 5 .

As shown in FIG. 5 , the grounding unit 400 in this embodiment includes a rigid member 420 , a reinforcing member 440 , a grounding panel member 450 and a flange 480 , and the rigid member 420 is A screw thread may be formed in a portion protruding to the upper portion of the main body 100 to be coupled to the street lamp 2 .

And the reinforcing member 440 is connected to the rigid member 420 to extend to the bottom of the body part 100 , and the ground panel member 450 is provided with a copper plate and is connected to the reinforcing member 440 and the body part 100 . It may be formed at the bottom.

In addition, the flange 480 may be inserted into the reinforcing member 440 together with a portion of the ground panel member 450 under the ground panel member 450 .

The rigid member 420 is made of a material such as reinforcing bars with no gaps inside, and a screw thread is formed on the protruding upper end to be a connection part coupled to the street lamp 2 .

And the lower end is inserted into the reinforcing member 440 through the upper portion of the main body (100).

As shown, the reinforcing member 440 has a hole formed therein, and may be deformed by an external force to restrain the rigid member 420 inserted at the top.

In addition, the reinforcing member 440 may be adjusted in length to set the height of the street lamp base 1 in a downward direction along the longitudinal direction corresponding to the shape of the hollow part 200 .

At this time, the rigid member 420 is formed to be long, and a portion thereof is bent at least once in the longitudinal direction and inserted into the reinforcing member 440, and the position at which the rigid member 420 is inserted may be the height of the street light base (1). have.

And the plurality of rigid members 420 may be connected to each other by welding a separate reinforcing bar.

As described above, since the rigid member 420 has a shape in which the reinforcing member 440 is inserted and constrained, it has an effect of facilitating assembly.

Meanwhile, a separate clamp 460 is mounted on the upper portion of the rigid member 420 .

The clamp 460 shown in FIG. 6 may be provided in a form that surrounds a portion of the rigid member 420 on the upper portion of the rigid member 420 in which a screw thread is formed, and a thread is formed on the inner circumference of the rigid member 420 . ) It is rotated through the upper screw thread and can be lifted and lowered, and a portion of the perimeter is cut off and then combined to bind the upper periphery of the rigid member 420

Therefore, the conventional screw thread nut can be easily coupled to the upper portion of the rigid member 420 instead of the trouble of inserting it by turning.

The reason why the clamp 460 is coupled to the upper end of the rigid member 420 is that when the concrete is poured into the formwork, it is possible to identify the exact location where the concrete is poured, as well as the upper portion of the rigid member 420 . When the street lamp (2) is combined in the, it may be to prevent the concrete from sticking to the screw thread and hardening. In addition, the length at which the screw thread formed at the end of the rigid member 420 protrudes can be adjusted.

Subsequently, the ground panel member 450 may be coupled to the lower end of the reinforcing member 440 .

As shown in FIG. 7 , the ground parts 452 have a protruding shape by removing a part of the ground panel member 450 , and the flange 480 is inserted into the removed part to bend the ground parts upward.

The flange 480 includes a support part (not shown) formed larger than the diameter of the reinforcing member 440 to support the lower end of the reinforcing member 440 and an insertion part (not shown) that is inserted into the reinforcing member 440 and is in close contact with the inner surface. city) is separated.

The insertion part is made of a material having elasticity and is formed in a cylindrical shape with a space formed therein, a portion is vertically cut along the circumferential direction, and the end portion inserted into the reinforcing member 440 is formed to be tapered upward, so that the reinforcement member 440 is formed. ) can be inserted smoothly.

Accordingly, it is inserted into the reinforcing member 440 together with the grounding parts 452 , and there is an effect that the grounding parts 452 are brought into close contact with the inner surface of the reinforcing member 440 by elastic force.

On the other hand, since the street light foundation 1 according to an embodiment of the present invention creates the body part 100 in a manner of pouring the concrete into the formwork, the air tube 340 penetrates to create the penetration part 300 . After being inserted into the part 300 and curing the concrete, the air tube 340 may be removed to form the penetrating part 300 .

The formation of the through part 300 through the air tube 340 will be described with reference to FIGS. 8 to 11 .

The air tube 340 has an air inlet member 342 formed at an end thereof to inject air therein.

At this time, by controlling the air inlet member 342 to the air tube 340 to discharge the internal air to reduce the volume, it can be easily removed from the concrete by applying an oil component such as a lubricant to the outer surface of the air tube 340. .

When the concrete is injected into the formwork and the air of the air tube 340 is drawn out after curing is performed, the penetrating part 300 is formed, and the friction force between the air tube 340 and the penetrating part 300 is reduced, so that the penetrating part easily At 300 , the air tube 340 may be removed.

In addition, for the removal of the air tube 340, a product capable of reducing friction, such as a lubricant, may be applied around the air tube 340 when it is installed.

Therefore, it is preferable that the penetrating part 300 is bent enough to put a hand into the hollow part 200 because the bent angle is gentle.

To this end, it may be preferable that the angle of the inner side of the bent portion is smoother than the angle of the outer side, that is, the bent angle is relatively larger.

This is because the inlet of the through part 300 in the body part 100 is at a lower position in the vertical direction than the hollow part 200 .

On the other hand, it may be formed in the through part 300 in a deformed form of the air tube.

Next, the manufacturing process of the street light base 1 according to the present invention will be described.

First, the formwork may be prepared and the hollow box 200 and the grounding unit 400 may be disposed therein.

The hollow box 200 may have a connection pipe 260 at an upper portion and a drain pipe 240 formed at a lower portion, and the connection pipe 260 may be disposed to extend upward through the opening hole 101 .

The grounding unit 400 combines the rigid member 420 and the reinforcing member 440 to extend from the opening hole 101 toward the lower part of the formwork, and at this time, it may be arranged so as to fit horizontally and vertically.

At this time, by coupling the clamp 460 to the rigid member 420 , the height of the plurality of rigid members 420 protruding into the opening hole 101 can be made uniform, and can be arranged vertically and horizontally. .

Then, an air tube 340 or tube 350 connecting the hole around the formwork and the hollow box 200 is mounted, and concrete can be poured into the formwork.

At this time, the clamp 460 is positioned between the formwork and the rigid member 420 to prevent the poured concrete from leaking out of the formwork.

After putting concrete (such as ready-mixed concrete) inside the formwork and curing it for a certain period of time, the formwork and the air tube 340 are removed. to form a conduit 320 .

After the concrete is cured, a part of the grounding panel member 450 may be inserted into the reinforcing member 440 from the lower portion of the grounding unit 400 to be connected.

At this time, the grounding parts 452 formed on a part of the grounding panel member 450 insert a separate flange 480 into the reinforcing member 440 , and the grounding while inserting the flange 480 into the reinforcing member 440 . The parts 452 may also be disposed inside the reinforcing member 440 together.

The manufacturing process of the street light base 1 may be performed on a flat ground, or after digging a place where the street light will be located, it may be performed at the digging position. In an unavoidable case, it may be manufactured in a factory and transported to a place where the street lamp 2 is located.

When pouring concrete into the formwork, it is desirable to use a vibrator to apply a certain vibration so that the concrete fills well.
