Abstract
The utility model relates to a reinforced concrete electric pole with a wave-shaped steel wire ring reinforced rod used for lighting, electric and communicating aerial circuits. The utility model is characterized in that wave-shaped steel wires are taken as the lengthwise main reinforcing bars of the electric pole without stretching force, and ordinary reinforced concrete production technology is utilized. On the premise that 20% steel is saved, the intensity of the bending resistance, the crack resistance and the scratching resistance of the electric pole is enhanced.
Description
The utility model relate to be used to throw light on, the electric pole of overhead wire such as electric power, communication.
Now various in style, in the different electric pole of shape and structure, using the widest is circular pole.In existing circular pole, three kinds of major products are arranged, (1) Circular reinforced concrete pole; Its production technology is simpler, and deficiency is that intensity is lower, and from great, materials are many, and particularly anti-crack ability is poor, and the tensile region tends to cracking under regular service conditions, and its amount of deflection is big simultaneously.(2) Circular prestressed concrete pole; Though the deficiency place that the energy degree differently solves Circular reinforced concrete pole, but it has a fatal weakness, that is exactly that it exists because of heavily stressed creeping in a large number of causing, in case the crack occurs, very easily cause moment to destroy, and needing stretch-draw control corollary equipment aborning, technical requirements is also higher.(3) annular partially prestressed electric pole has mainly increased the toughness of electric pole, and purpose is to solve because of heavily stressed to cause the hidden danger that moment destroys.Its deficiency place is that mechanical property is lower than prestressed concrete electric pole, and breaking resistance has reduced by 20%, simultaneously its complex technical process.
The utility model purpose is an advantage of bringing into play above three kinds of electric poles effectively, solves their deficiency place, provides a kind of technology simple, and is few with material, cracking resistance, anti-crawl agentdefiection, flexural strength height, the concurrent with better mechanical property.
The purpose of this utility model is achieved in that the lengthways main steel bar of electric pole adopts waved wire to substitute conventional in the past straight line steel wire.This is that indentation straight line steel wire more effectively improves concrete adhesion stress because waved wire can be than screw thread.In addition, waved wire is formed through pressing ripple by the straight line steel wire, the hardening of its material owing to strengthen, thereby intensity is improved, production technology is identical with the technology of existing annular concrete electric pole, the cage of reinforcement that is about to tie is packed in the steel mould for electric pole, the concrete that pouring stirs, ECDC lid, fastening, last centrifugal forming.
Advantage of the present utility model is owing to adopted the ripple steel wire to substitute the conventional reinforcing bar muscle of deciding, thereby can save steel material more than 20%, and its mechanical property significantly improves.Through actual measurement, compare with the GB396-84 national standard, average bending resistance, breaking resistance are 287.4% of GBs, are 215% of design strengths, average flexing resistance is 325.4% of a GB, is 248.2% of design strength.Waved wire annular concrete electric pole, under the situation that does not need stretch-draw and prestressing, its mechanical strength really can reach Circular prestressed concrete pole mechanics standard.Measured result: compare with the GB4623-84 GB, average bending resistance, breaking resistance are 139% of GBs, and flexing resistance is 161% of a GB.Compare with GB4623-84 GB partly prestressed pole, average bending resistance, breaking resistance are 174% of GBs, and flexing resistance is 225% of a GB.
Below in conjunction with accompanying drawing the utility model is further described
Fig. 1 is a cross-sectional view of the present utility model
Fig. 2 is the utility model A-A sectional drawing
With reference to Fig. 1, Fig. 2, the lengthways main steel bar 2 of electric pole skeleton is for the wave mode steel wire is circular layout, and is equipped with the upright circle 3 of frame and is bundled into the electric pole skeleton and combines formation the utility model with the concrete 1 of pouring.
