Hollow sandwich high-strength steel pipe concrete telegraph pole

Abstract

The invention belongs to the technical field of telegraph poles, and particularly relates to a hollow sandwich high-strength steel pipe concrete telegraph pole. The hollow sandwich high-strength steelpipe concrete telegraph pole comprises a pole body. Perpendicular door type moving plates are sequentially connected to the pole body from bottom to top in an inserted manner, and windproof plates are arranged at the contact positions of every two adjacent door type moving plates in the same horizontal direction. Through the door type moving plates and the windproof plates, under the windproof action of the windproof plates, wind pushes the door type moving plates to move in the wind flowing direction, the other ends of the multiple door type moving plates extrude the adjacent door type moving plates downwards, the multiple door type moving plates are extruded closely, and downward extrusion force is generated to the pole body; meanwhile, the pole body and the door type moving plates arehard to stagger, and the pole body is more stable; and wind is guided to the thin portion of the top of the pole body, the function of blocking wind of the top of the pole body is weak, correspondingly, acting force of wind to the pole body is small, the anti-wind capacity of the pole body is further enhanced, and the strength of the pole body is improved.

Description

technical field [0001] The invention belongs to the technical field of electric poles, in particular to a hollow interlayer high-strength steel pipe concrete electric pole. Background technique [0002] A pole is a pole for a wire. The cross arm is an important part of the pole. It is an angle iron fixed horizontally on the top of the pole, and there is a porcelain bottle on it to support the overhead wire. The function of the cross arm is to install insulators and fittings to support wires and lightning conductors, and to keep them at a certain safe distance according to regulations. [0003] In some areas with a lot of wind, when the wind blows the pole body for a long time, the pole body is prone to tilt under the action of strong wind, and even breaks in severe cases. In view of this, the invention provides a hollow interlayer high-strength steel pipe concrete utility pole , which has the ability to press down on the rod body when there is a strong wind, and can guide ...
