Central axis keeps vertical, and error is not greater than ± 1.0mm.However, in the past, in production and assembly formula taper circular pole,
Due to not correct connecting elements molding positioning process and operating instruction, to instruct and specification assembly type taper circular pole
The processes such as assembly, measurement and the positioning of connecting elements and the molding positioning of its framework of steel reinforcement, operator's randomness of leaving molding are fixed
Position causes every section assembly type taper circular pole connecting elements connection plane and the verticality of electric pole central axis unqualified, raw
There is plane skew in every section assembly type taper ring electric pole connecting elements connection that output is come, and assembly type taper circular pole is caused to go out
Larger skew is showed, the curvature of assembly type taper circular pole is unqualified after assembling.

It a) is in horizontal positioned state by the central axis of assembly type taper circular pole or taper pole framework of steel reinforcement；
B) lifting rope of the ceiling hammer about 1.0m that lengthens is permitted, with hand by rope end hold, keep ceiling hammer freely sagging, slowly
Until mobile vertical line almost connects end face, the gap between vertical line and connecting end surface is observed；If it was found that lower section is there are gap,
Behind connection steel part with hand hammer percussion lower section, move forward connecting end surface, until its connecting end surface and vertical line are comprehensive certainly
By until contacting；If it was found that top there are gaps, gently tapped with hand hammer behind above connecting end surface, make connecting end surface to
Preceding movement, until its connecting end surface and the comprehensive contact free of vertical line.
For assembly type taper circular pole, the connection plane to every economize on electricity bar connecting elements is in electric pole central axis
Verticality, which measures, to be necessary, and is measured, is controlled and precise positioning to above-mentioned verticality to realize, just must be fast
Speed accurately finds the assembly type taper circular pole central axis i.e. central axis of electric pole framework of steel reinforcement, keeps its horizontal
State, then measuring basis is become with it, and it is vertical to use the messenger wire of cross square crossing method ceiling hammer to be formed by with central axis
Straight line is measuring basis, and the verticality in two freedom degrees of connection plane is measured and positioned respectively, so that it may relatively be held
The assembly type taper circular pole with connecting elements of easy perpendicularity deviation very little.
The technological core of right-angled intersection vertical line correction positioning mode is:
1) with the taper of assembly type taper circular poleOn the basis of, previous level placement electric pole framework of steel reinforcement is born flat
Platform is pressedThe gradient become continuous slope along its length, so that electric pole framework of steel reinforcement is placed on the bearing stage after technological transformation
After upper, center axis thereof remains horizontal positioned state, conveniently make the central axis of horizontal positioned framework of steel reinforcement really at
For connecting elements squareness measurement, school reference of reference；
2) when being attached component assembly, using right-angled intersection vertical line correction method, and by rolling reinforcing bar on cushion cap
The method of skeleton, realize in connecting elements connection plane in two freedom degrees its verticality with framework of steel reinforcement central axis into
The effective measurement of row and control, by the control of its error of perpendicularity in ± 1.0mm.
The mechanism that the present invention skew occurs to assembly type taper circular pole connecting elements is analyzed, and specific aim mentions
Prevent assembly type taper circular pole connecting elements connection plane from the methods and techniques measure of skew occur out, to assembly type taper
Circular pole connecting elements molding positioning, process undergo technological transformation, by changing the upper of Making of reinforcement cage bearing stage
The state of plane, by flat-changed-into-sloping, the central axis after framework of steel reinforcement is placed is in horizontal positioned state, makes horizontal positioned steel
The central axis of tendons skeleton becomes correction reference, then introduces " right-angled intersection vertical line orthosis ", with the vertical principle of ceiling hammer and side
Method implements simply and effectively correction and measurement to the verticality of connecting elements connection plane and framework of steel reinforcement central axis, maximum
Limit simplifies molding positioning flow, reduces correction difficulty.
