Abstract
It is a kind of control steel strand wires elasticity modulus method be related to cable production line technique, be specifically related to it is a kind of control steel strand wires elasticity modulus strand structure design.It is mainly to solve the problem of that the elasticity modulus fluctuation of current steel strand wires influences anchoring quality and invent greatly.In strand structure design, the diameter proportion of central hair and Bian Si is determined first, central hair diameter is 1.033 times of side silk diameter, central hair diameter tolerance+0.01mm, side silk diameter tolerance ± 0.01mm, wire rupture force value deviation≤0.5kN, 14 times of laying pitch coefficient, the practical lay pitch deviation≤3mm of steel strand wires realizes the control of steel strand wires elasticity modulus within 195 ± 3GPa.Advantage is can to accurately control steel strand wires elasticity modulus to be in standard intermediate range, and fluctuation range is small, realizes that the control of steel strand wires elasticity modulus within 195 ± 3GPa, meets the requirement of the key projects such as high-speed rail.
Description
Technical field:
The present invention relates to cable production line technique, the strand structure for being specifically related to a kind of control steel strand wires elasticity modulus is set
Meter.
Background technique:
In steel strand wires use process, elasticity modulus is an important technical indicator, determines stretching in steel strand tension construction
Long rate, if the elasticity modulus fluctuation of steel strand wires is big, the elongation of steel wire bundle is different when tensioning, can reduce prestressing force effect,
Anchoring quality is influenced, the control range of elasticity modulus is required in key project higher and higher.In order to meet the engineerings such as high-speed rail
Requirement to steel strand wires elasticity modulus devises the steel strand wires method of control elasticity modulus, realizes to steel strand wires elasticity modulus
It accurately controls.
Summary of the invention:
Technical problem to be solved by the invention is to provide it is a kind of by improve steel strand wires in respectively constitute steel wire proportionate relationship and
Dimensional accuracy improves combo and twisting parameter, realizes the control of steel strand wires elasticity modulus in the control steel strand wires elasticity of intermediate range
The method of modulus.
Above-mentioned purpose is achieved in that working out influences steel strand wires elasticity modulus by improving strand structure design
Structural parameters control steel wire diameter ratio and dimensional accuracy, work out and control steel strand wires combo and twisting parameter, realize steel strand wires
Elasticity modulus accurately controls.
Specific practice is: in strand structure design, it is first determined the diameter proportion of central hair and Bian Si, central hair are straight
Diameter is 1.033 times, central hair diameter tolerance+0.01mm of side silk diameter, side silk diameter tolerance ± 0.01mm, wire rupture force value
Deviation≤0.5kN, realizes the control of steel strand wires elasticity modulus 195 by 14 times of laying pitch coefficient, the practical lay pitch deviation≤3mm of steel strand wires
Within ± 3GPa.
The invention has the advantages that the design method is by improving strand structure design and combo twisting parameter, Ke Yizhun
Really control steel strand wires elasticity modulus be in standard intermediate range, and fluctuation range is small, realize steel strand wires elasticity modulus control 195 ±
Within 3GPa, meet the requirement of the key projects such as high-speed rail.
Detailed description of the invention:
Fig. 1 is the cross-sectional view of steel strand wires of the present invention, and 1 is side silk in figure, and 2 be central hair；
The schematic view of the front view of the position Fig. 2 steel strand wires of the present invention, 2 be side silk in figure, and 3 be the lay pitch.
Specific embodiment:
Referring to Figures 1 and 2, by improving strand structure design, the structural parameters for influencing steel strand wires elasticity modulus, control are worked out
Steel strand wires combo and twisting parameter are worked out and controlled to steel wire diameter ratio and dimensional accuracy, realizes that steel strand wires elasticity modulus is accurate
Control.
Specific practice is: in strand structure design, it is first determined the diameter proportion of central hair and Bian Si, central hair are straight
Diameter is 1.033 times, central hair diameter tolerance+0.01mm of side silk diameter, side silk diameter tolerance ± 0.01mm, wire rupture force value
Deviation≤0.5kN, realizes the control of steel strand wires elasticity modulus 195 by 14 times of laying pitch coefficient, the practical lay pitch deviation≤3mm of steel strand wires
Within ± 3GPa.
