Abstract
The invention provides a method for fixing electric pole ends without releasing partial prestress. The method includes steps of prefabricating a concrete pole body, installing the corrosion-resistant electric pole ends and fixedly installing low-relaxation helical rib steel wires; enabling the aperture of the upper end of the concrete pole body to be smaller than that of the lower end of the concrete pole body; installing the corrosion-resistant electric pole ends at the upper end and the lower end of the concrete pole body; fixing the corrosion-resistant electric pole ends to the concrete pole body by the aid of the low-relaxation helical rib steel wires to guarantee that an effect of the prestress can be effectively realized. The method has the advantages that the corrosion-resistant electric pole ends are connected onto the concrete pole body by the low-relaxation helical rib steel wires, so that the effect of the prestress of an electric pole can be effectively realized, operation is simple, the method is easy to implement and popularize, and the technological cost is low; T-shaped low-relaxation helical rib steel wire through holes are formed in joints of the low-relaxation helical rib steel wires and the corrosion-resistant electric pole ends, so that the low-relaxation helical rib steel wires can be prevented from falling off, the service life of a product can be prolonged, and safe power supply can be guaranteed.
Description
Technical field
The present invention relates to power supply unit method field of manufacturing, be specially a kind of nothing and put a partly prestressed pole termination fixing means.
Background technology
Concurrent has two kinds of ordinary reinforced concrete electric pole and prestressed concrete electric poles.That the section form of electric pole has is square, octagon, I-shaped, annular or some other profiled-cross-section.What the most often adopt is ring section and square-section.Whole of electric pole length is generally 3～18 meters.Circular pole has two kinds, tapered rod and isometrical bar, and the true footpath of tapered rod is generally 150～550 millimeters, and tapering is 1:75; The diameter of isometrical bar is 300～550 millimeters; Both wall thickness are 40～80 millimeters.
The 80's, Chinese development centrifugal process Circular prestressed concrete pole.Its manufacturing process is mainly by steel-wire carcass longitudinally stretch-draw in punching block, then makes concrete under centrifugal action, excessive moisture be extruded, thereby greatly improves concrete density and intensity.In order to make concrete can reach quickly the more than 70% of design strength, can carry out stream curing, to shorten the demoulding cycle.Use prestressed concrete electric pole than using ordinary reinforced concrete electric pole saving steel, and can also improve crack resistance and application life.
But electric pole connection end is all to use common flange part at present, can not give full play to the prestressed effect of underrelaxation helix rib steel wire.
Summary of the invention
Technical problem solved by the invention is to provide a kind of nothing to put a partly prestressed pole termination fixing means, to solve the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: a kind of nothing is put a partly prestressed pole termination fixing means, comprise the following steps: the precast concrete body of rod, installation anti-corrosion electric rod end head, installation be underrelaxation helix rib steel wire fixedly, described concrete body of rod upper port footpath is less than lower end bore, the upper and lower two ends of the concrete body of rod are provided with anti-corrosion electric rod end head, anti-corrosion electric rod end head is fixed on the concrete body of rod by underrelaxation helix rib steel wire, guarantees to realize better prestressed performance effect.
Described underrelaxation helix rib steel wire is T-shaped underrelaxation helix rib steel wire, on anti-corrosion electric rod end head, offer underrelaxation helix rib steel wire through hole, underrelaxation helix rib steel wire through hole is also T-shaped, underrelaxation helix rib steel wire one end is inserted and is fixed to electric pole body of rod inside, underrelaxation helix rib steel wire termination and the seamless fusion of underrelaxation helix rib steel wire through hole through underrelaxation helix rib steel wire through hole.
beneficial effect of the present invention:the present invention by connecting anti-corrosion electric rod end head by underrelaxation helix rib steel wire on the concrete body of rod, effectively brought into play the prestressed action effect of electric pole, simple to operate being easy to realized, low being easy to of process costs popularized, underrelaxation helix rib steel wire and anti-corrosion electric rod end head junction are provided with T-shaped underrelaxation helix rib steel wire through hole, prevent that underrelaxation helix rib steel wire from coming off, increase product application life, power supply ensures safety.

The specific embodiment
In order to make technological means of the present invention, creation characteristic, workflow, using method reach object and effect is easy to understand, below further set forth the present invention.
As Figure 1-3, a kind of nothing is put a partly prestressed pole termination fixing means, comprise the following steps: the precast concrete body of rod 1, installation anti-corrosion electric rod end head 2, installation be underrelaxation helix rib steel wire 4 fixedly, the described concrete body of rod 1 upper end bore is less than lower end bore, the concrete body of rod is provided with anti-corrosion electric rod end head 2 in two ends Shang Xia 1, anti-corrosion electric rod end head 2 is fixed on the concrete body of rod 1 by underrelaxation helix rib steel wire 4, guarantees to realize better prestressed performance effect.
Described underrelaxation helix rib steel wire 4 is T-shaped underrelaxation helix rib steel wire 4, on anti-corrosion electric rod end head 2, offer underrelaxation helix rib steel wire through hole 3, underrelaxation helix rib steel wire through hole 3 is also T-shaped, underrelaxation helix rib steel wire 4 one end are inserted and are fixed to electric pole body of rod inside, underrelaxation helix rib steel wire 4 terminations and the 3 seamless fusions of underrelaxation helix rib steel wire through hole through underrelaxation helix rib steel wire through hole 3.
The present invention is simple in structure, easy to make, and cost of manufacture is low, can coordinate electric pole to give full play to the prestressing force effect of underrelaxation helix rib steel wire in electric pole, strengthens the crack resistance of electric pole, improves electric pole application life, ensures power supply safety.
