Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary power pole used in a house construction work, and more particularly to a structure of a pole pipe used as a temporary power pole.

[0002]

2. Description of the Related Art When a single-family house is constructed, temporary power poles have conventionally been used in order to enable use of various electric tools and lighting at night. Building work involves the use of various power tools and the need for night lighting in accordance with the effects of weather and other work site schedules. Conventionally, as shown in FIG. Such a temporary power pole 1 generally takes an electric wire 4 from a power pole 3 closest to an architectural house 2.

Conventionally, the temporary utility pole 1 has used a normal metal tube (metal pole) having a certain height required for the site.
When setting up, start by deciding where to stand and digging a hole in that place. Excavation dimensions in this case are, for example, a depth of 60 to 100 cm, a diameter of about 50 to 80 cm,
A metal tube having a total length of about 3 to 5 meters was erected on the erect hole, and a temporary telephone pole was erected.

[0004]

Recently, it has been pointed out that a minimum standard of height should be set for such a conventional temporary pole. If the height of the temporary utility pole is too small,
This is because there is a risk that an unic vehicle or other various work vehicles may be caught by the temporary electric wire and cause an accident.

[0005] Therefore, the temporary poles currently proposed are at least 5.2 m or more, and poles having a height of at least 6.2 m or more when drawing electric wires over a general roadway may be used. It is desirable.

However, as described above, when a tall pole having a height of 5.2 m or more is to be erected on the site, it is necessary to dig into the ground more than conventional erection work, and at least a metal of 45 kg or more is required. It is necessary to carry the pole to the site and to support the pole vertically during soil covering work, which constrains the precious working time of staff and increases the risk of work. Become. In residential construction, improvement of work safety and efficiency is particularly desired in recent years.However, stricter conditions for erecting temporary utility poles are necessary to secure sufficient safety and efficiency for construction workers operating with a small number of people. This is a very difficult task.

Accordingly, an object of the present invention is to make it possible to easily and erected a temporary pole pole having a length of more than 5 to 6 m easily, in a short time, and safely by one working staff. is there.

[0008]

In order to achieve the above object, a temporary electric pole for residential building according to the present invention comprises a pile member previously driven into the ground and a drop-in pole connected and fixed to the pile member via a connecting member. The pile member is provided with a sharp driving and expanding surface at a tip end thereof, and is provided with a vertical panel having a substantially horseshoe shape standing up along the axis of the pile member at a rear end thereof. The vertical panel is provided with a bolt hole at an appropriate place, while the connecting member is provided at its rear end with a slit for fitting the vertical panel, and the slit is provided at one end surface of the tubular connecting member. And a pair of vertically elongated bolt fitting holes are provided at positions corresponding to the bolt holes of the vertical panel.

[0009]

FIG. 4 shows the entire structure of a temporary power pole according to the present invention. The temporary power pole 10 according to the present invention includes a pile member 11 for driving in advance into the ground,
And a pull-in pole 20 that is connected and fixed via a connecting member 30 to the pull-in pole 20. The present invention is particularly applicable to the connection member 30 and the pile member 11.
And connection structure.

First, regarding the length of each member, the pile member 11 is about 120 cm, the connecting member 30 is about 40 cm, and the upper retracting pole is about 4 meters in total length. The draw-in pole 20 may be divided into two tubes for the sake of transportation. In this case, a so-called Sayakan 19 is connected in the middle and connected by appropriate means to function as a single pole. Since the connecting member 30 connects the pile member 11 and the drop-in pole 20, this member does not affect the total length of the temporary utility pole.

FIGS. 5A and 5B show an example of the structure of the pile member 11. FIG. The pile member 11 has an acutely widened inclined surface (pyramid or conical shape) 14 at its tip. At the rear end (upper end), there is provided a vertical panel 15 having a substantially horseshoe shape as a whole.
The shape of the vertical panel 15 is not limited.
It is necessary to raise the connecting member 30 vertically after installing the panel horizontally, and it is preferable that at least the upper part of the vertical panel 15 be formed in an arc shape in consideration of the movement trajectory of the connecting member 30.

FIG. 1 and FIG. 2 show an example of the structure of the connecting member 30. The connecting member 30 has a slit 31 for loosely fitting the vertical panel 15, and the connecting member 30 is substantially 90 degrees around the pipe axis O as shown in FIG. A pair of bolt insertion holes 34 and 35 are formed at positions having the above positional relationship. Since the slit 31 is engaged with the vertical panel 15, it is formed so as to reach the lower end surface of the connecting member 30. Also, the lowermost ends D of the bolt insertion holes 34, 35
Is formed from a position below the uppermost end U of the slit 31 and always has an upper and lower portion (indicated by a symbol W) which overlap each other.

Next, a method of erecting a temporary utility pole using the connecting member 30 will be described. Prior to construction, first, pile member 1
Hit 1 into the ground. Since the vertical panel 15 is provided on the upper part of the pile member 11, a hammer receiving member 40 as shown in FIG. 6, for example, is used in this operation. Cast from.
Reference numeral 43 denotes a slit that fits into the vertical panel 15.

Next, a drop-in pole 20 having a predetermined length
The connecting member 30 is fixed to the lower end of the. Although not shown, for example, three bolts (bolts each of which is directed to the axis) are arranged on the upper part of the connecting member 30 and
What is necessary is just to screw it firmly into the bolt fixing hole formed in the lower end part of 0.

In this state, the slit 31 of the connecting member 30
Is fitted to the vertical member 15 of the pile member 11, and the connecting member 30
A bolt 50 of an appropriate length is inserted from one of the bolt insertion holes 34. In this case, the slit 31 is fitted to the vertical panel 15 in a horizontal state as shown in FIG. This is because the entire length of the pull-in pole 20 is long and cannot be vertically set from the beginning. In other words, the pole is inserted sideways, and the weight of the pole is loaded on the Raising the pole vertically is a feature of the present invention. The bolt 50 inserted from one of the bolt insertion holes 34 passes through the bolt hole 16 of the vertical panel 15 and the other bolt insertion hole 35, and is loosely tightened. In this state, the bolt 50 is in a freely movable state, and is not tightly tightened.

In this state, the bolt 50
Is located at the lowermost end D of the bolt insertion holes 34 and 35.
The opposite surface of the slit 31 is closed, and the vertical panel 1
This is because the position of the bolt 50 is uniquely determined by the lateral width of the bolt 5 and the inner diameter of the connecting member 30. Of course, bolt 50
Is in a state in which it can move freely, and when the retracting pole 20 is started up, it may exhibit a slight vertical movement.

With the connecting member 30 temporarily fixed to the vertical panel 15 via the bolt 50, the pull-in pole 20 is raised vertically. This operation can be easily performed by one worker. This is because the lower end of the pull-in pole 20 is supported by the upper end of the pile member 11 and the long pole weight is shared and supported by the pile member 11. Get up easily.

When the retracting pole 20 rises substantially vertically,
In the preferred embodiment, coupling member 30 falls slightly downward. This is because the inner diameter of the connecting member 30 is set to be larger than the outer diameter of the pile member 11, and the bolt 50 moves to the uppermost end P of the bolt insertion holes 34 and 35 and stops. The upper ends of the bolt insertion holes 34 and 35 function as positioning stoppers. This method uses the connecting member 30.
Is not included in the total length of the temporary pole, and the upper pole is dropped and fixed inside the connecting member when the pole is started up. Of course, the descending dimension at that time is arbitrary, and the vertical dimensions of the bolt insertion holes 34 and 35 can be arbitrarily set accordingly.

In this state, the work of erection of the temporary utility pole is temporarily completed. However, since the pile member 11 is not always accurately driven vertically, the upper retraction pole 2
The possibility that the angle of 0 is also inclined remains. Therefore, as described above, it is desirable to adjust the angle of the pull-in pole 20 by using three bolts arranged above the connecting member 30. Since these three bolts point toward the center of the tube, it is possible to tilt the pole in any direction by loosening one of the bolts. Even if you loosen one bolt,
Since the two bolts support 2/3 (= 240 degrees) of the entire circumference, the pole does not fall.

As described above, according to the temporary utility pole according to the present invention, the remaining pole weight can be significantly reduced by separately and independently handling the pile members from the entire length. As a result, a single work staff can establish a utility pole that meets the power company's new safety regulations. In this embodiment, the pile member 11 is assumed to be about 1.2 meters, but this length can be considered to be a length sufficient to reduce the weight of the upper pole. This corresponds to about 1/5 of a pole that has a maximum of 6.2 meters. For example, if the original total weight is 50 kg, the weight is reduced by 10 kg.
Below the limit weight (45 kg) that makes handling difficult,
Since the weight becomes 40 kg, and it is only necessary to perform the lever movement from the viewpoint of the upper surface of the pile member, the working efficiency and the safety are remarkably improved as compared with the conventional whole standing method.

Assuming a minimum length of 5.2 meters, the total weight is reduced from 45 kg to 36 kg, and the standing work can be performed by leverage, so that the working efficiency is obviously improved. .

[0022]

As described above, according to the temporary power pole according to the present invention, a long temporary power pole of more than 5 to 6 m can be erected easily, quickly and safely by one work staff. It is possible to do.
