Description

An underbracing apparatus enabling supporting electric pole that supports the supporting structure according to the terrain

The present invention relates to an easy-to-support device capable of supporting a supporting structure according to a terrain capable of easily supporting a supporting structure by maximizing a supporting cross-sectional area of the supporting body, but easily inserting the root body regardless of the diameter of the buried hole. .

A structure made of concrete, etc., which is buried and installed to fix the pole or branch at the lower part of the pole or branch line, is called Geunga. It is possible to maintain the stable installation state of the pole through the support power of the pole pole, and it is common for the pole pole to have a rectangular or semicircular shape.

In this way, the Jeonju and Jiseon lines that support Jeonju, which supports electric power facilities, and the branch line contracts signed therein play an important role in maintaining the upright state of Jeonju. In particular, it is said that the role of Geunju in soft ground and slope is important.

Looking at the general electric pole construction, after auger pit is excavated using auger crane and the electric pole is inserted into the excavated pit, equipment and manpower such as a backhoe are put into operation to install a rectangular rod-shaped root of approximately 1.2m in length. After additionally excavating sufficient area to allow installation, the work is done in the form of installing and installing backfill near the pole in the vertical direction where tension is applied.

Until now, a lot of techniques for fixing the teeth and fixing them have appeared, for example, briefly explaining the patent registration No. 945390, "Fixed installation structure of the pole poles using the fastening means of the reverse fastening structure and the pole poles embedded with the fixing member" When installing a groove on one surface of the rectangular root (2) and attaching the grooved part to the outer circumferential surface of the electric pole (1), fastening the nut (4) to the U bolt (3) to install it is a general root value installation so far. It is a structure (refer to Fig. 1 하지만), but the root value has a problem such as support capacity in soft ground.

Therefore, in order to improve the support capacity in the soft ground, Patent Registration No. 923067 "Installation and Construction Method of Preclinical Workpiece Fixing Members and Precast Workplaces Using It" appeared. Briefly explaining the technical details, the work price made of concrete to improve the support power Positioning grooves 2a and positioning projections 2b are formed on the upper and lower surfaces of (2), respectively, so that the upper surfaces are in contact with the outer circumferential surface of the front pole (1), and the two roots are stacked in an "L" shape and U It is installed by fastening the nut 4 to the bolt 3, and at this time, it is installed so that the positioning projection is inserted into the positioning groove located on the two superimposed overlapping surfaces (see FIG. 1 )).

However, all of these conventional roots have a problem in that the diameter of the buried hole must be made largely larger than necessary because it is installed prior to inserting the electric pole into a buried hole that has been previously dug into the ground to reclaim the electric pole. There is a problem in that the time required is increased, and furthermore, there is a problem in that the bearing capacity of the electric pole is reduced due to the diameter of a large buried hole.

In addition, all of the conventional roots are combined with the electric pole by a'U'-shaped fastening means. In this case, considering that the diameter of the electric pole becomes narrower as the electric pole is directed toward the upper side, it is also applied to the weak external force applied to the electric pole. As the fastening part of the'U' shape is loosened, a problem may arise, which does not properly fulfill the excuse of the near price due to the play.

The present invention is intended to solve the problem of the rooting related to the function of the fixing key due to the supporting force and the rotational force of the tensile force by the electric wire, etc., which is the purpose of installation, to facilitate insertion into the buried hole but maximize the supporting cross-sectional area for supporting the electric pole It aims to provide a possible value.

In addition, another purpose is to prevent the loosening of the fastening part by the fastening means even with the external force of the electric pole having a gradient shape, and to provide a value that can stably support the electric pole by retaining the function of a fixed key against the rotational force. have.

It is characterized in that by digging the outer wall of the buried hole to unfold it, the supporting cross-sectional area with the bottom surface for supporting the support structure can be maximized by being wider than the diameter of the buried hole.

In addition, the root member is fixed to the rotating body and one side rotatably coupled to the rotating member by the installation member and the rotating shaft, but is extended so that the outer wall of the buried hole is dug by the rotation of the rotating body to open the support structure. It is preferred to include supporting muscles.

It is preferable that the edge portion is formed so as to easily dig the outer wall of the.

In addition, it is preferable that the muscle member further comprises an anti-rotation means for fixing the rotation body which is rotated to prevent the muscle body unfolded by rotation of the rotation body from rotating in the reverse direction.

In addition, the installation member is formed by protruding a pair of band bodies adjacent to each other on the outer surface of the band body and a plurality of band bodies coupled by fastening means so that the inner surface is in contact with the support structure in a shape fit but surrounds the outer surface of the support structure. It is preferable to include a hinge piece rotatably coupled to the member.

In addition, the band body further includes a flange on the inner surface of which the lower end of the support structure is seated, wherein the support structure seated on the flange is inserted into the band member through a through hole formed in the band body when the root member is rotated. It is preferable to fix the outer surface of the support structure by pressing.

In addition, the band body has a different circumferential length of the band body that is coupled to the outer surface of the support structure so that the muscle member can be densely installed at a position where a load of a distribution facility installed on the support structure is heavily loaded.
