Description

Concrete wire pole

Technical field

The utility model relates to a kind of electric pole that installs electric wiring that is used for power domain, especially refers to a kind of concrete wire pole.

Background technology

The Chinese utility model that existing a kind of patent No. is called " a kind of concrete wire pole " for the CN200620092684.3 name discloses a kind of structure and has been, the bottom of electric pole is plugged in the cover that blocks water by socket, and by tack coat sealing sealing.Owing to installed the cover that blocks water additional in the electric pole bottom, stop formation water to be filled in the electric pole cavity, thereby prevented the damage of freezing of electric pole bottom, prolonged the application life of electric pole, and prevented that the phenomenon of collapsing because of freeze thawing from taking place.The electric pole that adopts the utility model scheme to make suits to use at the high and moist rainy cold district of groundwater table especially.The shortcoming of this structure is, the first, and the structure of this electric pole does not have grounding function, meets the thundery sky electric pole and is shocked by electricity easily; Second cage of reinforcement is firm not enough, thereby reduces electric pole windproof ability; The 3rd, the positioner of measuring circuit is not set on the electric pole, the surveying work after can installing electric pole bring tired fiber crops.So its structure awaits to improve.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of sound construction, rated wind velocity big and arrester concrete wire pole easily is installed at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this concrete wire pole, include the body of rod, in the body of rod, axially be provided with cavity, it is characterized in that: the described body of rod is made by reinforcing bar and mixed earth, described reinforcing bar includes vertical reinforcement and hoop places the circle muscle on the vertical reinforcement to form, be welded with and the suitable endless metal circle of the circular bottom part shape of the body of rod in the bottom of vertical reinforcement, and be welded with metal derby in endless metal circle bottom surface.

As improvement, described circle muscle may be selected to be the helical form cranse on the toroidal frame periphery that vertical reinforcement surrounds, and this circle muscle can be preferably the whole piece reinforcing bar that connects from beginning to end.

Improve, the described body of rod is the little truncated cone-shaped structure of bottom enlarged head again, and the radical of described vertical reinforcement is that successively decrease two structure of compartment is arranged on the body of rod from the bottom of the body of rod to head, has so both kept reinforced steel bar strength, and has saved steel again.

As further improvement, the described body of rod welds the whether annular steel ring of conducting of circuit in the promising measuring stick body on the steel hoop frame that vertical reinforcement surrounded, the side of this annular steel ring is provided with projection, this projection is provided with and is used for the jack that the measuring instrument plug inserts, in this jack, be provided with internal thread, and the end face of this jack is mutually concordant with the cement outer peripheral face that is positioned at the body of rod.

Improve again, the bottom of described metal derby by reinforcing bar in the body of rod through the projection of annular steel ring be installed on the body of rod on the grounding wire of arrester be connected and form the earth terminal of earth lead.

Improve, described vertical reinforcement is to be embedded on the side face of annular steel ring again, makes vertical reinforcement and annular steel ring fixing more reasonable firm.

Improve, described body of rod compartment of terrain on the steel hoop frame inwall that vertical reinforcement surrounded is welded with the annular steel coil of stiffener frame intensity, thereby has further strengthened the intensity of reinforced frame again.

Improve, the described body of rod may be selected to be truncated cone-shaped, cylindrical, oval, square, rhombus or polygon etc. again.

Compared with prior art, the utility model adopts the body of rod to be made by reinforcing bar and mixed earth, described reinforcing bar includes vertical reinforcement and hoop places the circle muscle on the vertical reinforcement to form, be welded with and the suitable endless metal circle of the circular bottom part shape of the body of rod in the bottom of vertical reinforcement, and be welded with metal derby in endless metal circle bottom surface.The advantage of this design is that reinforced frame is more reasonable more firm, and last body of rod bottom surface is welded with the endless metal circle, thereby the reinforced frame structure that vertical reinforcement is surrounded is more firm; Again owing on the endless metal circle, be welded with metal derby, not only increased the Area of bearing of body of rod bottom, and the bottom of metal derby by reinforcing bar in the body of rod through the projection of annular steel ring be installed on the body of rod on the grounding wire of arrester be connected and form the earth terminal of earth lead.Have again, but the utility model adopts the body of rod to be welded with the annular steel ring of stiffener frame intensity on the toroidal frame that vertical reinforcement surrounded, and a side of annular steel ring is provided with the projection of hollow, the end face of this projection is positioned on the cement outer peripheral face of the body of rod, this has not only further strengthened the fastness of reinforced frame, and the surveying work of measuring whether conducting after can also installing electric pole brings convenience, the end face of the hollow convex column of measurement and positioning portion is concordant with the cement side surface of the body of rod, avoiding electric pole when transportation to damage projection, and make the whole appearance of electric pole also more attractive in appearance.
