Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0036] As mentioned in the background technology, in the prior art, the magnetic flux method is used to measure the force of the prestressed steel cable. The existing magnetic flux method is not feasible for stainless steel cables with weak energy or magnetic permeability.

[0037] Based on this, the present invention provides a cable force measurement method for stainless steel cables. By replacing at least one of the stainless steel wires constituting the pre...

Abstract

The invention provides a method and a system for measuring a cable force of a stainless steel cable, and relates to the technical field of stress measurement. The method comprises the steps of: replacing at least one stainless steel wire forming a prestressed cable with a carbon steel wire with magnetic conductivity; and arranging a magnetic flux sensor on the outer side of the detected prestressed steel cable for measuring the corresponding magnetic field physical quantity so as to obtain a cable force value of the prestressed steel cable. The system comprises the detected prestressed steel cable and the magnetic flux sensor, wherein the prestressed steel cable contains the carbon steel wire with magnetic conductivity, and the magnetic flux sensor is arranged on the outer side of the detected prestressed steel cable and used for measuring the corresponding magnetic field physical quantity. The method and the system solve the problem of application of the magnetic flux method in the stainless steel cable, greatly optimize the measurement problem of the stainless steel cable, and greatly reduce the cable force measurement cost of the stainless steel cable.

Description

technical field [0001] The invention relates to the technical field of stress measurement, in particular to a method and system for measuring the cable force of a stainless steel cable. Background technique [0002] With the development of modern construction industry, as a green, low-carbon building component-prestressed steel cable component, it is widely used in large bridges, In airport waiting halls, terminal buildings, high-speed rail stations and large commercial buildings. Because of the above characteristics, prestressed steel cables generally play an important role in the above-mentioned building structures, such as the prestressed cable-stayed bridge connecting the tower column and the bridge body through prestressed steel cables, it can be said that the prestressed steel cables can bear almost 60 The importance of -80% dead load of the bridge body and the loads of vehicles and pedestrians walking on it can be imagined. Because of its important "position" in the...
