Description

TELEGRAPH POLE USING BASE WITH SUPPORTER AND ANCHOR}

The present invention relates to an installed telegraph pole using a support for a helix anchor restraint constructed with a helix anchor. More specifically, by using the helix anchor restraint support constructed by the helix anchor to reinforce the lateral restraint force of the telegraph pole, the helix anchor restraint support constructed by the helix anchor with improved construction ability can be secured while improving the supportability. It's about telephone poles.

In general, telegraph poles are pillars that support electric wires such as telegraphs, telephones, lights, etc., including wooden poles and reinforced concrete poles.

The wooden pole is low in price, light in weight, easy to transport, but low in durability due to its low durability, and reinforced concrete is inexpensive and capable of mass production, and most of the pole pole is made of concrete.

Of course, there are cases in which steel poles are made of steel, but the economic feasibility of low-cost poles can be called reinforced concrete.

The reinforcement concrete stock is placed in the mold and the steel wire and PC steel wire, and the PC steel wire is pre-tensioned at the end of the mold and settled, then the concrete is poured into the mold, the mold is installed in the centrifugal molding machine and the mold is rotated Through centrifugal molding to form a hollow tube. The mold is moved to a curing room to cure concrete, and the final production is completed by demolding the mold.

In addition, Figure 1a is a front view showing a conventional telephone pole (10, or street lamp) construction diagram.

That is, the telephone pole 10 is constructed so that the lower portion is embedded in the ground (G), which can be called a method of using the telephone pole underneath.

To this end, excavation of the ground (G) to buy the telephone pole 10, but if the support of the ground is insufficient, the construction of the pole pole (10) will be conducted.

Therefore, as shown in FIG. 1B, the auxiliary steel 20 may be attached to the lower portion of the telephone pole 10 to prevent such conduction. In this case, however, the installation of the auxiliary steel 20 is inevitably accompanied with workability and economical deterioration.

Furthermore, as shown in FIG. 1c, there is an example of further constructing the reinforced concrete foundation 30 in the lower pole of the telephone pole 10. In this case, the amount of excavation of the ground is increased, and materials and manpower required for construction of the foundation are inevitably consumed.

In addition, even when the telephone pole 10 is installed in this way, a crack occurs on the surface of the telephone pole 10, and such cracks are generated mostly near the ground surface.

That is, as shown in FIG. 1D, most of the cracks occur at about 1.0D on the upper surface and about 1.5D on the lower surface (where D is the average diameter of the whole pole). The cracks have a horizontal force due to earth pressure and external force. It can be said to be the most occurring site. Therefore, it is necessary to reinforce the cracking site, and in fact, as the time passes, the cracking becomes larger, and the final telephone pole is inevitably replaced.

2 illustrates a construction example of a conventional helix anchor 10.

The helix anchor is a tube-shaped pile, and a plurality of spiral rotating blades 11 are spaced apart on the outer circumferential surface thereof so as to install the pile by a method of fixing the helix anchor 10 by rotating it on the ground.

Since the helix anchor 10 plays the same role as the anchor body, the helix anchor 10 is installed on the earth plate on the ground slope formed by breaking the ground.

Looking specifically, the ground (G) is installed a large number of thumb anchors 30 spaced apart and the earth plate 50 is installed between the thumb anchors.

Accordingly, the helix anchor 10 is inserted into the ground plate back ground by penetrating the earth plate 50.

Next, the tension anchor bolt 12 is connected to the helix anchor 10 inserted into the rotation.

Next, the tension anchor bolt 12 is passed through the belt anchor (wale, 40) while installing the belt anchor (wale, 40) on the thumb anchor 30, and then the anchor anchor bolt (not shown) with a jack (hydraulic jack). 12) is tensioned to introduce a tension force (tensile force), and settled using a fixing nut 20 in the band (Wale, 40) to introduce the prestress to the helix anchor (10).

Therefore, the present invention is installed by using the support for the restraint helix anchor restraint, helix anchor that can secure a more reliable support and constructability in the construction of the restraint support for helix anchors and reinforce the transverse restraint force of the whole pole It is to be a technical problem to solve the provision of the installed telegraph pole using the support for the restraint helix anchor construction.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

[Installed Telegraph Pole Using Helix Anchor Restraint Supported by Helix Anchor: Example 1]

3A, 3B, and 3C illustrate an assembled perspective view, a completed perspective view, and a construction cross-sectional view of the telegraph pole 100 using the helix anchor restraining support 200 installed as the helix anchor 300 of the present invention.

The pole pole 100 is a steel pole pole or concrete pole pole is used, the bottom portion is formed with a lower support 110 to be connected to the upper end of the support helix anchor constraint support 200 to be described later.

The lower support 110 may include a bottom plate 111 formed on the lower surface of the telephone pole and a reinforcement plate 112 (triangular piece form) installed between the bottom plate 111 and the outer surface of the telephone pole.

Accordingly, the bottom plate 111 is connected to each other by a top plate 210 of the helix anchoring support 200 and a fastener 120 such as a bolt and a nut.

The helix anchor restraint support 200 is a portion where the helix anchor 300 to be described below is installed while replacing the reinforced concrete foundation 30 as shown in FIG. 1C.

The helix anchoring restraint support 200 is manufactured using steel. The reason for using steel is that it can be manufactured in advance and immediately installed on site.

The support for the helix anchor anchor 200 is to be formed of the body portion 220 is made of steel, the front end portion 230 is preferably formed in a wedge shape to be embedded in the ground.

First, the body portion 220 may be formed by radially arranging the I-type steel based on the center, and the guide tube is attached to the center of the plurality of I-type steel so that the helix anchor which will be described later is vertically inserted in the center. Can be formed. The guide tube 233 may be formed of a steel pipe to form the upper and lower through holes (211,231) to be described later.

Thus, the overall shape can be produced in the form of upper and lower stepped steel assemblies.

That is, it is preferable that the lower part of the helix anchoring restraint support 200 in which the earth pressure is largely made larger and the upper part has a multi-stage diameter having a smaller diameter than the lower part.

An upper plate 210 is formed on an upper surface of the body portion 220.

In this case, an upper through hole 211 is formed in the center of the upper plate 210, and a lower through hole 231 is formed in the center of the front end portion 230, so that the upper and lower through holes 211 and 231 coincide with center lines. The helix anchor 300 is to pass through the center of the support for restraining the helix anchor in the vertical direction.

The helix anchor 300 is a tube-shaped pile, and a plurality of spiral rotating blades 310 are spaced apart on the outer circumferential surface to install the pile by a method of rotating the helix anchor 300 on the ground by press-fitting.

Accordingly, the helix anchor 300 is installed by digging and rotating the ground surface, and rotates through the upper and lower through holes 211 and 231 of the helix anchoring support 200 to the helix helix anchor 300 to rotate on the ground G. The helix anchor restraint support 200, through which the helix anchor penetrates, is stably installed in the ground according to the press-installation.

The helix anchor 300 installed in the ground penetrating the center of the helix anchor restraint support 200 serves as a pile of the helix anchor restraint support 200 so that the support of the helix anchor restraint support when the ground is particularly soft ground. Becomes possible.

In addition, the upper portion of the support for the helix anchor anchor 200 is exposed to the outside to effectively support the large horizontal force generated near the ground surface.

In addition, the helix anchor restraint support 200 may be further inclined to the helix anchor 300.

That is, the helix anchor 300 inclined support 240 that can be inclined to install the helix anchor 300 on the surface of the helix anchor restraint support, helix anchor restraint support when installed inclined in the ground helix anchor 300 The support for the more stable helix anchor anchor 200 in the state to minimize the (200) is to be able to support.

Therefore, the helix anchoring restraint support 200 of the present invention can secure a sufficient support force by the helix anchor 300, thereby minimizing the size of the helix anchoring restraint support 200, and thus the helix anchoring restraint support ( 200) It is possible to minimize the amount of ground breakage for installation, which enables more economic pole foundation construction.

Of course, one helix anchor 300 is installed in the center of the support helix anchor constraint, but helix anchor 300 is installed obliquely may be installed radially two or more on the support helix anchor constraint 200.

Furthermore, when the helix anchor 300 is fixed to the helix anchorage restraint support 200 by introducing a tension force after rotational indentation, the helix anchor restraint support body 200 and the helix anchor 300 are integrally installed. The support 200 and the helix anchor 300 may serve as a permanent anchor in which prestress is introduced, thereby enabling a highly efficient telephone pole installation.

As a result, the helix anchor restraint support member and the helix anchor installed vertically or inclined can reinforce the transverse restraint force of the telephone pole, and in particular, have a significant reinforcement effect on the horizontal force resistance required for seismic performance.

[Installed Telegraph Pole Using Helix Anchor Restraint Supported by Helix Anchor: Example 2]

4A and 4B illustrate another installation example of the telegraph pole 100 using the helix anchor restraining support 200 installed as the helix anchor 300 of the present invention in a complete perspective view and a construction cross-sectional view.

That is, the helix anchor restraint support 200 may be manufactured as a support for restraining the reinforced concrete helix anchor by disassembling the form after curing the concrete (C) after reinforcement in a formwork (not shown).

Such a synthetic helix anchor restraint support member uses a precast helix anchor restraint support body made of pre-manufactured reinforced concrete.

Of course, when used as a support for precast helix anchor restraint will be manufactured to maintain the lower through-holes as described above.

To this end, the guide pipe member 250 is pre-inserted into the center of the helix anchorage restraint support 200 so that upper and lower through-holes can be formed, and after the concrete is poured so that the guide pipe member is embedded, the top plate is finished. Just do it.

It is preferable to form a stud on the outer circumferential surface of the guide tube member 250 to be integrated with the concrete (C), the guide tube member 250 is further extended from the upper and lower surfaces of the support helix anchoring support 200 helix anchor 300 Guided).

In addition, since the above-described support for the helix anchor constraint 200 supports the telephone pole 100, it is preferable to form a ground hole in the support for the helix anchor constraint and to allow the grounding of the forward pole.

That is, the ground hole 260 may be formed as a horizontal tube extending horizontally from the center of the guide tube member and exposed to the trunk portion 220 and connecting a ground line not shown to the horizontal tube.

Therefore. As in the first embodiment, the upper through-hole 211 is formed in the center of the upper plate 210 of the helix anchor restriction support 200, and the lower through-hole 231 is also formed in the center of the front end portion 230, The upper and lower through-holes 211 and 231 are centered so that the helix anchor 300 penetrates.

The helix anchor 300 is also a pile of pipe-like piles on the outer circumferential surface is spaced apart a plurality of helix anchor 300 is installed on the ground by rotating the helix anchor 300 in the press-fit method.

Accordingly, the helix anchor 300 is installed by excavating and rotating the ground surface, and restraining the helix anchor in the excavated space by penetrating the upper and lower through holes 211 and 231 of the support for the helix anchor restriction 200 to the helix anchor 300. It is all day to allow the support to be seated,

In addition to the helix anchor restraint support 200, the helix anchor 300 is installed inclined further, but the helix anchor 300 is installed obliquely may be installed radially two or more on the helix anchor restraint support 200.

The helix anchor restraint support and the helix anchor installed vertically or inclined can reinforce the transverse restraint force of the telephone pole, and in particular, can have a reinforcement effect on the horizontal force resistance required for the seismic performance. Example 1 and the helix anchor restraint support It can be seen that there is a difference in making the concrete member.

[Installed Telegraph Pole Using Helix Anchor Restraint Supported by Helix Anchor: Example 3]

5A to 5D illustrate another embodiment of the telegraph pole 100 using the helix anchor restraint support 200 installed as the helix anchor 300 according to the present invention. And helix anchor 300 may be referred to as variations.

That is, the upper end is connected to the base block 400 installed on the ground so that the lower end of the telephone pole 100 is connected to the helix anchor restraining support 200 disposed to be positioned in the ground on the helix anchor 300 that is rotationally press-fitted in the ground. Helix anchor restraint support to be installed so as to be an embodiment to serve as the middle bulb of the helix anchor.

First, the case of Figure 5a

First, the helix anchor 300 is installed to be inclined a large number between the upper end and the lower end of the helix anchor 300, the helix anchor restriction support 200 having a torso portion 220 formed in a wedge shaped wedge is It can be seen that it is installed in the ground (G) in a fixed state.

The helix anchoring restraint support 200 may be formed to a size that does not interfere with the indentation when indented in the ground, and when the helix anchor restraint support 200 is buried in the ground, it becomes inclined because it acts as a kind of bulb. It is possible to support a stable load of the helix anchor 300 is installed.

It can be said to be used when the ground is very soft.

Furthermore, after the minimum burr for forming the foundation block 400, the upper end of the helix anchor 300 is connected to the lower support 110 of the telephone pole 200.

Since the lower support 110 is formed in a horizontal plate shape, the upper end of the inclined helix anchor 300 connects the upper end of the helix anchor 300 to the lower support 110 using a bending connector 130. It can be seen that.

Accordingly, by forming a foundation block 400 of reinforced concrete blocks using cast-in-place concrete using a formwork not shown in the burrowed space, the foundation block 400 protrudes above the ground surface and the upper end of the helix anchor 300 is the foundation block. To be embedded at 400.

In addition, the helix anchor restraint support and the inclined helix anchor can reinforce the lateral restraint force of the telephone pole, in particular, it can have a significant reinforcement effect on the horizontal force resistance required for seismic performance, and the first embodiment and the helix anchor restraint support It can be seen that there is a difference in that it is made of concrete members, and the basic block is minimized, and it can be said that it is advantageous for horizontal force reinforcement by installing a support for restraining the helix anchor in the ground.

5B is the same as that of FIG. 5A, but the upper end of the helix anchor 300, which is inclined to the lower support 110 of the telephone pole 100, is used as it is without using a bending connector on the lower support 110. 110).

Accordingly, the lower connecting plate is formed such that the end of the lower connecting plate is bent side plate so as to penetrate the upper end of the helix anchor 300 inclined, and after installing the helix anchor 300 in the bending side plate, the fixing nut ( 140) and tighten after tightening.

This makes it possible to secure a more secure support of the helix anchor (300).

Accordingly, as shown in FIG. 5B, the helix anchor 300 is connected to the telephone pole 100, but the helix anchor 300 is provided with the support block 200 for restraining the helix anchor and the foundation block 400 is the same as that of FIG. 5A. Proceeds.

FIG. 5C illustrates a case where the helix anchor 300 is vertically installed. In this way, the lower support 110 of the telephone pole is also formed in a horizontal plate shape, and the upper end of the helix anchor 300 is installed to pass through the lower support 110, and then tension and fasten the fixing nut 140 after tension Let's go.

Thus, as shown in FIG. 5C, the helix anchor 300 is connected to the telephone pole 100, but the helix anchor 300 is installed such that the support for the helix anchor restriction 200 is installed and the foundation block 400 is installed in FIGS. 5A and 5A. The same proceeds as in FIG. 5B.

Although not shown, as shown in FIG. 5B, the lower connecting plate having the bent side plate is formed, but the combination of vertical and inclined helix anchors 300 may be used.

Furthermore, FIG. 5D illustrates a case in which the upper end of the helix anchor 300 is not connected to the lower footrest of the telephone pole, unlike FIGS. 5A to 5C.

That is, the helix anchor 300 is first installed using the helix anchoring restraint support 200 in the ground, and the upper end is buried in the base block 400, and then the lower part of the telephone pole on the upper surface of the base block 400. It can be said to connect the part with anchor bolt.
