Goal of the invention of the present utility model just provides a kind of intensity height, little tip footpath, cost is low, manufacturing process is simple, and can replace the following circuit tangent suspension tower of 110KV of existing height below 32 meters, the combined type annular steel concrete tapered electric pole of straight line concrete filled steel tube electric pole.
Combined type of the present utility model annular steel concrete tapered electric pole divides electric pole to join in order by more piece to combine, every joint divides electric pole to be made up of reinforcing cage, stirrup and concrete, key of the present utility model is that upper end and stirrup welding that power transmission muscle, this power transmission muscle are set in the reinforcing cage upper end are fixed, and its lower end is arranged in reinforcing cage.Every joint divides the power transmission muscle of electric pole to be provided with the 4-6 root, and every length is 50～100 centimetres, and is distributed on the circumference of reinforcing cage.Because stirrup is positioned at the outside of every economize on electricity masthead portion and bottom; and reinforcing cage is arranged in electric pole; the inboard of the outside and stirrup cast centrifugal concrete in reinforcing cage; therefore in order to guarantee that reinforcing bar has 1.5 centimetres protection thickness; power transmission muscle in the reinforcing cage welds mutually with stirrup; be lined with a little steel plate between power transmission muscle and stirrup, the power transmission muscle is welded on the little steel plate, then little steel plate is welded on the inside wall of stirrup.In addition, an end of non-prestressing tendon is welded on the stirrup inside wall in the reinforcing cage, and the other end is fixed in the reinforcing cage by interior stirrup and spiral bar.Each joint in combination divides in the electric pole, and a bottom joint divides the non-prestressing tendon of electric pole to divide the stirrup on electric pole top to weld mutually with this joint, and all the other each joints divide the non-prestressing tendon in the electric pole all to weld mutually with the stirrup of its underpart.Topmost a joint and bottom saves to divide in the electric pole power transmission muscle is not set.In addition, owing to be provided with the power transmission muscle, variation has taken place in the reinforcing bar layout structure of the reinforcing cage in the electric pole, makes each joint divide the intensity of electric pole connecting joint vicinity to be guaranteed.
Adopt the utility model, its advantage is:
1. manufacturing process is simple.Owing in the reinforcing cage of electric pole, be provided with 4～6 power transmission muscle, can cancel the form of traditional non-prestressing tendon in the welding of bar head, thereby because non-prestressing tendon must cut-off by fixed length in presstressed reinforcing steel elongation institute, and need to adopt and add the technology of wearing the muscle cover when having avoided that reinforcing cage applied prestressing force.Adopt the power transmission muscle to simplify the manufacturing process and the manufacturing cost of electric pole greatly.
2. intensity height.Under the condition that satisfies the electric pole pressure angle, polygamy is put the quantity of presstressed reinforcing steel, can reduce the quantity of non-prestressing tendon relatively, and got rid of in the electric pole manufacturing process in the past the set muscle cover worn in the middle of the non-prestressing tendon, therefore the intensity of electric pole increases substantially, relative weight obviously reduces, and uses bending moment to reach 377KNM at 2 meters of root, can be widely used in 110KV and following various straight line poles and the multi-thread bar strain insulator corner pole altogether of 10KV.
3. saving steel.Since an amount of increase the radical of presstressed reinforcing steel, reduced non-prestressed radical, the total burn-off of reinforcing bar is reduced, the overall weight of electric pole is reduced, and further reduces cost.
Fig. 1 is the generalized section of a sectional mast in the utility model general structure, and the layout structure schematic diagram of non-prestressing tendon 1, presstressed reinforcing steel 2, power transmission muscle 3, stirrup 4, extension gusset 5, little steel plate 6, concrete seven is wherein arranged.
