Abstract
The utility model relates to a high-taper combined annular reinforced concrete electric pole which is a high strength electric pole composed of multiple sections of high-taper annular reinforced concrete branch electric poles. The taper of each branch electric pole is respectively between 1: 50 and 1: 60; the electric pole is composed of seven sections of branch electric poles at most; the length of each sections of the branch electric pole is respectively three meters, three meters, six meters, six meters, six meters, six meters, and two to two point four meters from bottom to top; the electric pole of each combined length is composed of any three continuous sections or more than three sections of the branch electric poles which are successively arrayed in the seven sections of the branch electric poles; the strength is high and the cost is low, and the utility model can be directly applied in a power line of voltage level which is 110KV or below the 110KV.
Description
The utility model is a kind of high strength electric pole that divides electric pole to combine by the big tapering steel hoop of more piece concrete, belongs to the technical field that reinforced concrete pole is made.
In the electric pole of existing steel concrete prestressing force, non-prestressed or partial prestressing, the tapering of its electric pole is 1: 75, according to the national standard of GB369-94 " Circular reinforced concrete pole " and GB4623-94 " Circular prestressed concrete pole ", the maximum bending moment that uses of the electric mark post of this tapering can only be applicable to that generally wire type does not have backguy as LGJ-150 or wire type is LGJ-185 band backguy straight line pole.And be LGJ-240,110KV power circuit for built on stilts wire type, the concurrent of this traditional tapering all can not satisfy the Technological Economy composite request on intensity and height.Therefore when circuit is crossed over house, power line, navigable river, can only select iron tower, concrete filled steel tube electric pole, clean steel pipe electric pole for use, and the manufacturing cost height of these electric poles, complex process is difficult to bear in many areas.
Goal of the invention of the present utility model provides a kind of pole height that can be applicable to the 110KV circuit, and the big tapering separable ring shape reinforced concrete pole that intensity is big, cost is low.
Big tapering separable ring shape reinforced concrete pole of the present utility model divides electric pole to connect up and down by more piece to combine, it is 1: 50～1: 60 that every joint divides the tapering of electric pole, this electric pole is made up of seven joints at most, each joint divides the length of electric pole to be respectively 3 meters of first segments, 3 meters at second joint, 6 meters at the 3rd joint, 6 meters at the 4th joint, 6 meters at the 5th joint, 6 meters at the 6th joint, 2～2.4 meters at the 7th joint from bottom to top, and the electric pole of every kind of pattern length divides any continuous three joints or the above branch electric pole of three joints arranged in order in the electric pole to combine by this seven joint.Wherein topmost a joint is fixed according to the tapering that sets electric pole for 2-2.4 rice, and promptly tapering is that 1: 50, the tip are 190 millimeters directly, and the length that goes up a joint most is 2.0 meters, and when tapering was 1: 55, the tip was 190 millimeters directly, and the length that goes up a joint most is 2.2 meters.When getting tapering and be 1: 60, the tip directly is 190 millimeters of φ, and the length that goes up a joint most is 2.4 meters.
The combining form of this electric pole mainly is the bar Gao Erding according to various requirement, be that combining form can divide electric pole, 7-3 joint to divide electric pole, 7-2 joint to divide electric pole, 7-1 joint to divide electric pole or 6-4 joint to divide electric pole, 6-3 joint to divide electric pole, 6-2 joint to divide electric pole, 6-1 joint to divide electric pole for the 7-5 joint divides electric pole, 7-4 joint, and the 5-1 joint divides electric pole, 4-1 joint to divide electric pole or the like, so long as the above electric pole that divides of continuously arranged three joints can make up.
Adopt big its advantage of tapering separable ring shape reinforced concrete pole of the present utility model to be:
1. the bending resistance of electric pole, breaking resistance obviously increase, and the amount of deflection of electric pole reduces.Because the flexural strength of electric pole is directly proportional with main muscle place diameter of a circle, the breaking resistance of electric pole mainly is directly proportional with the difference of 4 powers of the outer interior diameter in electric pole cross section, the difference of 4 powers of the outer interior diameter in the amount of deflection of electric pole and electric pole cross section is inversely proportional to, that is to say, the increase of the increase of pole diameter and electric pole master muscle place diameter of a circle, the flexural strength and the breaking resistance of electric pole are obviously increased, and amount of deflection is obviously reduced.And the utility model has strengthened the tapering of electric pole, strengthens pole diameter and the most effective way of electric pole master muscle place diameter of a circle just.
2. cost is low.Because the tapering of electric pole strengthens, the intensity of electric pole is obviously increased, therefore bear under the prerequisite of same intensity at electric pole, the main muscle of electric pole just can be saved many, the tip footpath of electric pole also can be reduced to 190 millimeters of φ, so both can alleviate the weight of electric pole, and also can reduce the material consumption of electric pole, thereby reduce cost and cost.The investment of this electric pole is respectively 53%, 68%, 66% of iron tower, concrete filled steel tube electric pole, the investment of clean steel pipe electric pole under the similar condition of function of use, and economic benefit is fairly obvious.
3. can be applicable to the height of 110KV power circuit and the requirement of intensity, when dividing electric pole all to use at seven joints of the present utility model, the electric pole that just can form 32-32.4 rice height replaces tangent suspension tower that common 110KV power circuit adopts, concrete filled steel tube electric pole etc.
4. divide electric pole rationally to connect at some joints, applicable to the multi-thread bar shaft tower altogether of 35KV, 10KV.
Fig. 1 is the generalized section that a joint divides electric pole in the general structure of the present utility model.Branch electric pole body 1, reinforcing cage 2, concrete 3 are wherein arranged, hang gusset 4, stirrup 5.
Embodiment of the present utility model is as follows:
Choosing the electric pole that is applicable to the 110KV power circuit is example, its tapering is 1: 55, and its tip is 190 millimeters directly, adopts whole seven joints to divide electric pole to combine, wherein from bottom to top, the first segment height is 3 meters, and the tip directly is 720.9 millimeters, and second joint highly is 3 meters, the tip directly is 666.4 millimeters, the 3rd joint highly is 6 meters, and the tip directly is 557.3 millimeters, and the 4th joint highly is 6 meters, the tip directly is 448.2 millimeters, the 5th joint highly is 6 meters, and the tip directly is 339.1 millimeters, and the 6th joint highly is 6 meters, the tip directly is 230 millimeters, the 7th joint highly is 2.2 meters, and the tip is 190 millimeters directly, and the height overall that is combined into this electric pole is 32.2 meters.The use bending moment at 2 meters of root reaches 377KNM, can be used as lead and for the LGJ-240/30 horizontal span be 980 meters 110KV straight line pole.During construction, divide electric poles to join successively at seven joints and be welded into an integral body, just realized the utility model.
