Abstract
The utility model discloses a C80 high-intensity concrete large-top-diameter partially prestressed electric pole. The C80 high-intensity concrete large-top-diameter partially prestressed electric pole comprises a pole body and a pole top bracket, wherein a cross arm is fixed at the upper end of the pole body through a supporting rod and a supporting rod hoop; and the bottom end of the pole body is connected with a foundation through fixing layer concrete and base layer concrete. The C80 high-intensity concrete large-top-diameter partially prestressed electric pole is relatively high in flexibility and crack resistance; cracks, deformation and fragile destruction can be well controlled under a use condition; the structure is safe and reliable; the bearing capacity and the bending torque are high; the assembled height is up to more than 30 meters; under the condition of the same bending torque, the using amount of steel of a large-bending-torque and high-top-diameter annular part prestressed concrete electric pole is less than that of a steel pipe tower and that of an iron tower; and during running, the C80 high-intensity concrete large-top-diameter partially prestressed electric pole is convenient to maintain and low in maintenance cost and can be used for 15 years or so.
Description
Technical field
The utility model relates to the large tip path portion of a kind of C80 strong concrete prestressed electric wire pole.
Background technology
Ordinary concrete electric pole, prestressed electric wire pole and steel pipe tower application life are shorter, steel quantity consumption large, the bearing capacity moment of flexure is little, safeguard loaded down with trivial details during operation and expense is high.
Summary of the invention
The purpose of this utility model just provides that a kind of steel quantity consumption is little, the bearing capacity moment of flexure is large, the large tip path portion of C80 strong concrete prestressed electric wire pole easy to maintenance during operation.
The large tip path portion of C80 strong concrete of the present utility model prestressed electric wire pole, comprise the body of rod, masthead support, cross-arm is fixed on body of rod upper end by strut and strut anchor ear, the bottom of the body of rod is connected with ground by fixed bed concrete, substrate concrete, the body of rod adopts Admixture and high-pressure steaming and cultivating to make strength grade of concrete can reach C80, there are 12.6 millimeters profiled bars of Φ 7～Φ to do the electric pole prestressed reinforcement with specification, adopt the indented bars of Φ 18 to do nonprestressed reinforcement.
The large tip path portion of C80 strong concrete of the present utility model prestressed electric wire pole, have preferably toughness and crack resistance, better crack, distortion and brittle fracture are controlled under the service condition, structural safety is reliable, and the bearing capacity moment of flexure is large, and assembled height can reach more than 30 meter, under the moment of flexure that equates, the large tip of large moment of flexure footpath annular partially prestressed concrete electric pole lacks than steel pipe tower and steel tower steel quantity consumption, and easy to maintenance and expense is few during operation, long service life is about 15 years.
Description of drawings
Fig. 1 is the utility model structural representation.
