[Industrial applications]

 The present invention relates to a screw-type utility pole used for a building pole and an adapter for a utility pole vehicle used to build a utility pole.

[0002]

[Prior art]

 A conventional digging pillar means will be described with reference to FIG. As shown in FIG. 13 (a), an earth auger 51 provided in the hole-digging column car 50 excavates a round hole having a size corresponding to the thickness and height of the utility pole. Next, as in (c), a crane is used to build a utility pole in the excavation hole. Check the verticality of the utility pole and refill the hole with the excavated soil as shown in (d). Backfilling is performed while compacting the soil. Finally, level the ground around the utility pole and clean it.

The problems of the conventional work procedure are as follows. The ground for digging a hole thicker than the diameter of the utility pole and backfilling it after building will weaken, and the bearing capacity for supporting the utility pole will decrease. For this reason, telephone poles with a large horizontal load require equipment such as branch lines and struts to resist tension. The hole excavation itself can use the mechanical power of the earth auger, but the sand sand picked up by the auger (removal and treatment from the auger) requires manual work (see Fig. 13 (b)). In addition, since the work such as backfilling of sand and sand, tamping, ground leveling, and cleaning after building columns requires human power, fatigue, danger, and stains on clothes occur. Depending on the location of the pillar, there is a risk of harming the surrounding area. Crop crops are damaged in arable land, roads are soiled by soil in urban areas, and shoulders are weakened in roads.

[Problems to be solved by the device]

 The present invention is to obtain a utility pole and an adapter for constructing a utility pole that do not require treatment of earth and sand and do not cause damage to the surroundings of the location of the building pole.

【Example】

 FIG. 1 is a perspective view of a screw-type electric pole of the present invention. The construction of the screw-type electric pole of the present invention will be described. The screw-type utility pole 1 has a hollow steel pipe 1-1 whose outer diameter at the tip is smaller than that of the bottom, and the lower end opening is configured as a serrated tooth portion 2, which is generally located at the position corresponding to the burial depth inside the steel pipe. At this point, a disc-shaped steel plate that will become the subsidence prevention plate 3 is welded and fixed to one sixth of the column length. For long columns, split type steel pipe joint columns are used, but the lower pipe is processed in the same manner as above. The length of the utility pole is, for example, 2.25 m to 3.40 m, the outer diameter of the upper part is 150 mm, the outer diameter of the lower part is 181 mm, and the thickness of the steel pipe is 3 mm.

FIG. 2 is a front view of an adapter (hereinafter referred to as “adapter”) P for a building column vehicle of the present invention, FIG. 3 is a sectional view taken along line AA ′ of FIG. 2, and FIG. It is a figure. The configuration of the adapter P of the present invention will be described. In the figure, 10 is a steel pipe, 11 is a square hole of the steel pipe, 12 is a drill shaft fixing pin provided on the upper part, 13 is a wire stopper, 14 is an upper ring spacer, 15 is a lower ring spacer, and 18 is a ring spacer guide part. , 19 are hooks for the buttocks.

The steel pipe 10 has a square hole 11, a disk-shaped lower ring spacer 15 is provided at the lowermost portion, and a ring spacer guide portion having a plurality of dish-shaped holes made of steel plates at the lower portion. 18 is attached, and a hook 19 for the rear hand is provided on the ring spacer guide portion 18. A drill shaft fixing pin 12 is provided at the upper part of the steel pipe 10, a disc-shaped upper ring spacer 14 is provided slightly below the middle part of the steel pipe 10, and a support part having a plurality of plate-shaped holes made of steel plates at the lower part. 14-1 is provided, and a steel plate is fixed to the upper part of the upper ring spacer 14 as a plate-shaped wire stopper 13 whose upper side is open. The upper ring spacer 14 is provided with true pole holes 20a, 20b for fixing poles and ring spacer fitting holes 21a, 21b for large diameters as shown in a sectional view taken along the line BB 'in FIG. The length of L of the adapter P is 1 m.

A procedure for constructing a pillar using the screw-type electric pole of the present invention will be described. As shown in FIGS. 9 and 11, an adapter is attached to the drill shaft 32 instead of the earth auger of the digger / columner 50.PInsert and fix with the drill shaft fixing pin 12. Next, from the upper opening of the screw-type power pole 1, the adapterPInsert. Further adapter P The bolts are inserted and fixed in accordance with the positions of the true rod holes 20a and 20b of the above and the true rod holes 4a and 4b of the fixing of the screw-type electric pole 1.

Prepare as described above, and install a screw-type telephone pole attached to an adapter for a construction pole vehicle at a planned construction pole location. While rotating the drill shaft 32 and adjusting the boom angle, etc., the screw-type utility pole 1 is vertically screwed into the ground, screwed to a predetermined depth, and then the adapter P is removed from the screw-type utility pole 1. For steel pipe joint columns, the crane is used to lift the upper pipe and fit it into the lower pipe.

The operation of the above configuration will be described. The subsidence prevention plate 3 prevents subsidence due to the load being applied to the utility pole for a long time after the building pole without the bottom plate as in the conventional case. The wire stopper 13 is a brim-shaped stopper that prevents the wire from coming to the boom side when the auger drill equipped with an adapter is wound by the wire and tightly stored in the boom 31 of the crane when the vehicle moves. .

When storing the tail hook 19, the tail of the storage wire is attached when the hook 19 is stored, and the drill shaft 32 is rotated to tightly fix the adapter to the take-up boom with the wire. The ring spacer of the adapter P is a spacer for bringing the auger drill into close contact with the inner peripheral portion of the steel pipe column. The upper spacer 14 and the lower spacer 15 form a pair at the upper and lower portions, and are fixed to the steel pipe column with bolts using the true pole holes 22a and 22b for fixing the electric pole. The ring spacer guide portion 18 of the adapter P has a taper on the lower side of the ring spacer so that the drill shaft 32 can be smoothly inserted when the drill shaft 32 is inserted into the screw-type electric pole 1.

By the way, since the screw-type utility pole of the present invention has various thicknesses, the size of the adapter P is constant. Therefore, when the screw-type utility pole is large, when the adapter P is inserted into the screw-type utility pole, the screw-type utility pole 1 There is a gap between the adapter and the adapter P. In the present invention, the large-diameter half ring 17 is attached to the upper ring spacer 14 in the above-mentioned case. Fig. 5 shows a front view and Fig. 7 shows a perspective view. FIG. 6 shows a sectional view taken along the line CC ′ of FIG. FIG. 8 is a sectional view showing a state in which the large-diameter half rings 16 and 17 are attached to the upper ring spacer 14. In the figure, 16a and 17a are true pole holes for fixing utility poles, 16a and 17b are spacer fitting projections, and 16c and 17c and 16d and 17d are connecting bolt holes. For steel pipe joint columns, a large diameter half ring is applied to the lower pipe.

[0013]

[Effect of device]

 Since the present invention is constructed by using the screw-type utility pole and the adapter having the above-mentioned configuration, (1) the work is simple, the work is completed in a short time, and the efficiency is improved. Compared with the conventional digging pillar method, there is no digging or backfilling work, so the ground bearing capacity is not impaired, and the self-supporting strength of utility poles is improved. Eliminates the need for manual labor The handling of soil and sand is eliminated, and clothes and other materials are less contaminated. Since no soil is discharged, cleaning work is not required and the surrounding areas of the building columns are not damaged.
