Description

[Detailed description of the invention] This invention relates to a multi-purpose support ring that taper-fits to a reinforced concrete utility pole.Specifically, it includes support rings for scaffolding nails, support fittings for building pull-ins, workbench mounting support fittings, cross-arm mounting supports. The purpose of the present invention is to provide a multi-purpose support ring for use as a support ring, for holding telephone lines, for holding branch lines, etc.

Hollow reinforced concrete utility poles that are currently in general use are manufactured by applying centrifugal force, making it difficult to form an integrally protruding exterior member.

For example, when installing scaffolding nails (bolts), it is not possible to make the scaffolding nails (bolts) protrude directly from the utility pole body, so bolt receivers are installed in advance by burying members at predetermined locations on the cylindrical reinforcement. Concrete is poured into utility poles while applying centrifugal force.

In this case, it is extremely troublesome to install the bolt receiver so that the members are arranged perpendicular to the longitudinal direction, and there is a risk that the bolt receiver may be oriented incorrectly during rotation.

For this reason, even if the scaffolding needle body is screwed onto the specified bolt receiver of the finished utility pole, it does not necessarily protrude exactly horizontally (horizontally), which may cause problems for workers when attaching the scaffolding. It has become a thing that brings about.

In addition, once the scaffolding needle body is installed, it must be removed, so when transporting or erecting the pole, it is not possible to roll the pole. It is something.

Furthermore, after the pillar is erected, in the case of fixed type scaffolding nails that always protrude, there is a risk that a third party may climb using the scaffolding nails, which may pose a danger.

Furthermore, even when attaching pole mounting members other than the scaffolding nails, a separate band tightening member is arranged and then attached, resulting in a time-consuming handling operation.

The present invention has been developed in view of the above circumstances, and its configuration will be described below with reference to drawings of embodiments.

1 is a taper 1a as a whole with different end diameter and base diameter.
A concrete utility pole body having a diameter l' equal to the diameter l at regular intervals in the longitudinal direction of the utility pole body 1.
An appropriate number of collar-shaped support ring bodies 2 having a constant width a are formed.

This support ring main body 2 has a flange portion 2 having a constant width at one end edge.
' is provided protrudingly, and a large number of locking holes 3 are bored in the flange 2', and an uneven part 4 having a chevron shape is arranged on the inner periphery of the ring main part 2''. It is configured to be elastically fitted to the utility pole main body 1 with its surface.

To explain the action of Iyoko, first select the support ring body 2 having a diameter corresponding to the diameter of the utility pole at a predetermined position on the utility pole body 1 (for example, the spacing between commonly used scaffolding nails), and attach it to the utility pole. If the support ring body 2 is fitted from the end 1b side which is the top of the main body 1, the support ring body 2 will be stuck at a predetermined radial position of the telephone pole and will be attached as a so-called collar fitting.

In this case, if the upper edge 2a'' of the support ring main body 2 is appropriately hit with a mallet or the like toward the base end (see Figure 3), the support ring main body 2 can be is pressed against the telephone pole surface, exerting a kind of spring action, and the telephone pole body 1
Coupled with the widening of the diameter based on the taper 1a that it has, a strong elastic fit is achieved, resulting in a fixed installation with no movement during rotation or removal.

Hereinafter, an appropriate number of support ring bodies 2 having diameters corresponding to the diameters of the utility pole bodies 1 at each predetermined interval are sequentially fitted, and then the utility pole bodies 1 are erected.

Here, for example, when using a scaffolding needle when climbing the utility pole main body 1, a support metal fitting 5 having engaging legs 5a shown in FIGS.
Insert the pair of engagement legs 5a into the two locking holes 3 in the flange 2' of the support ring main body 1 in an upright manner, and in this state rotate the scaffold shaft 5b by 90 degrees to bring it into a horizontal position. For example, the hooked engagement leg 5a rotates to face the lower surface of the collar 2', and the entire supporting hardware 5 stops horizontally (see Fig. 5A).
.

In this state, the user places his or her feet on the horizontally protruding support metal fittings 5 in the same way as with conventional scaffolding nails, places his or her hands on the support metal fittings 5, and climbs up in sequence.

Of course, in this case, the toes or arch of the foot may be directly hung on the flange 2' (this flange 2' has a diameter of, for example, 6 to 7 cm).
It exhibits a certain amount of overhang width, and the footrest can also be used as a cover).

Alternatively, a simple inverted support metal fitting 6 may be used as shown in FIG. 5B.

At this time, by simply dropping the hooked leg portion 6a of the inverted support hardware 6 from above into the gap between the inner grooves 4a of the concavo-convex portion 4 formed in the ring main portion 2'', the hooked leg portion 6a will be removed. Ring main part 2″
It is installed by being sandwiched between one side of the utility pole body.

In this state, the inverted support metal fitting 6 is installed in a horizontally protruding manner as described above.
All you have to do is put your hand on the scaffold shaft 6b and climb up.

Incidentally, these supporting metal fittings 5 or inverted type supporting metal fittings 6 are to be removed when unnecessary.

In addition, when using the support ring body 2 as a retainer for a house lead-in, a low-voltage branch, a telephone line, etc., the flange 2' of the support ring body 2 should be adjusted as shown in FIGS. Locking hole 3
Attach the proximal end of a fastening fitting 7 made of a simple or similar material to the bottom with a connecting bolt 8, and connect an electric wire 9 to the tip of the fastening fitting 7. This is to hold down the telephone line 9', etc.

When the support ring main body 2 is used as a beautification pole member, the support ring main body 2 is arranged at two places on the utility pole main body 1 as shown in FIGS. D-shaped pillar 1 constructed by bending an angle on the flange 2'
A semi-circular arc-shaped branch attachment piece 10a is brought into contact with the base end of 0, and is fixed with a connecting bolt 8.

That is, the mounting hole 10b formed in the branch mounting piece 10a of the D-shaped mounting column 10 is aligned with the retaining hole 3 of the collar 2', and the connecting bolt 8 is inserted into this.

An electric wire 9'' is installed on the D-shaped pole 10 installed in this manner.

Furthermore, when the support ring main body 2 is used as a workbench support metal fitting, the hook portion 11a protruding from the base end of the workbench main body 11 is connected to the flange of the support ring main body 2, as shown in FIGS. 8A and 8B. The lower end of the support arm 11b, which is hooked into the locking hole 3 of the utility pole 2' and protrudes diagonally from the lower part of the workbench body 11, comes into contact with the side surface of the utility pole body 1 to form a stand.

A worker stands on the workbench main body 11, which is horizontally extended and is mounted in this manner, and performs appropriate work such as inspecting the overhead wire 9.

As mentioned above, the present invention can be used for multiple purposes, and by making the support ring a ring body with a diameter that corresponds to the diameter of the predetermined mounting position of the utility pole body, and arranging an appropriate number of locking holes on the stallion edge, This support ring only needs to be installed after the utility pole is manufactured.For example, unlike the installation of conventional buried type scaffolding nails, when arranging the reinforcement that makes up the utility pole body, the scaffolding nail receiver eliminates the process of accurately burying the members, and is made of reinforced concrete. Making telephone poles becomes easier.

Of course, this integrally bent flange has a kind of rib effect on the support ring body and also serves to strengthen the support ring body.

Further, since a plurality of locking holes are bored throughout the entire area of the flange, there is no directionality for attaching supporting hardware, etc., which also leads to improved workability.

In addition, the support ring body is installed by arranging a diameter that corresponds to the taper of the utility pole itself and the diameter of the installation position, so it can be firmly fixed simply by fitting it into the support ring body. By simply engaging the desired metal fittings, it can easily be used as a substitute for scaffolding nails, support metal fittings for building lead-in work benches, support metal arms for mounting arms, telephone cable tie-downs, and other branch line tie-downs. It becomes something that grows.

Further, since the present invention has an extremely simple structure with a ring-like structure as a whole, it is easy to manufacture and can be provided at low cost, which provides practical effects.
