Background technology
Along with the fast development of China's electric utility, more and more higher to the technical requirements of power transmission and distribution circuit.Due to power transmission and distribution circuit joint use that loop increases, transmission pressure wire diameter increases, and the continuous increase of the span of electric line and height, intensity to power transmission and distribution electric pole, highly, moment of flexure all has higher requirement.Add resource-conserving industry development requirement, electric power transportation art is increasing to the demand of function admirable, economical and practical large moment of flexure concurrent.
In prior art; the patent No. is that the utility model patent of CN97222957.4 discloses a kind of annular partially prestressed concrete electric pole; comprise concrete body and be cast in presstressed reinforcing steel, non-prestressing tendon and the spiral bar in concrete body; non-prestressing tendon is connected with the steel ring at two ends; steel bar welding is connected to the inwall of steel ring, so just makes reinforcing bar have one deck concrete cover outward.But the form of structure of this reinforced concrete pole can not make the mechanical property such as electric pole moment of flexure, bar section amount of deflection be brought into play to greatest extent.
Utility model content
The purpose of this utility model is to provide a kind of unprotect layer concrete electric pole, to improve the moment of flexure of concurrent.
The technical scheme of unprotect layer concrete electric pole of the present utility model is as follows:
A kind of unprotect layer concrete electric pole; comprise the concrete body of rod and cage of reinforcement; described cage of reinforcement comprises the main muscle of longitudinal setting and is welded on the steel ring at main muscle two ends; described main muscle around the center line of electric pole along circumferentially-spaced; contain in lateral cross section main muscle, vertical with the center line of electric pole in any one of concurrent; on the cross section of each main muscle, distance electric pole center line point farthest drops on same cylindrical, and the outer contour of the cross section of the concrete body of rod also drops on described cylindrical.
One end that described steel ring is connected with main muscle offers the breach inserting for main muscle, and main muscle inserts in corresponding breach and welds with steel ring.
Described cage of reinforcement also comprises the vertical circle of frame, and described vertical circle is positioned at the annulus that main muscle surrounds and welds with main muscle.
Described cage of reinforcement surface is coated with galvanizing coating for protection against corrosion.
Described unprotect layer concrete electric pole is isometrical bar, and the external diameter of any one of the concurrent lateral cross section vertical with the center line of electric pole all equates.
Described unprotect layer concrete electric pole can also be the tapering tapered rod that is 1:75; the external diameter of the lateral cross section vertical with center line electric pole concurrent is from diminishing gradually to the bar tip at the bottom of bar; equate with the cross section external diameter at the bottom of bar with the steel ring external diameter being connected at the bottom of bar, the steel ring external diameter being connected with the bar tip equates with the cross section external diameter of the bar tip.
Unprotect layer concrete electric pole of the present utility model is simple in structure; it is outer without concrete cover by main muscle is set; main muscle reaches maximum apart from the distance of electric pole center line; when electric pole is in the time bearing outside lateral force or pressure, it is maximum that the moment of flexure that main muscle produces with respect to electric pole cross-section center reaches.Compared with prior art, make the anti-bending strength of electric pole and supporting capacity obtain promoting to greatest extent.And main muscle is arranged on layer of concrete surface, can bear larger stretching force, effectively avoid the layer of concrete face checking phenomenon causing because layer of concrete tensile strength is low.
The utility model has only used main muscle, does not use spiral bar, has saved the lace process of steel mesh reinforcement, and the manufacture craft of cage of reinforcement is very simple, has improved production efficiency.Do not use spiral bar also to save steel, compared with conventional concurrent, can saving steel consumption 10-15%.
