Detection device for steel strand inhaul cable and detection method thereof

Abstract

The invention relates to a detection device for a steel strand inhaul cable and a detection method of the detection device. The detection device comprises a support; a force transmission piece connected to the bracket in a horizontal moving manner; a cable clamp arranged in the support, wherein the top of the cable clamp is fixedly connected with the bottom of the force transmission piece in a detachable mode, a mounting part is formed at the bottom of the cable clamp, and the steel strand inhaul cable is fixedly connected with the mounting part in a detachable mode; a jack horizontally arranged on the bracket and vertically propped against the force transmission piece; and a pressure monitoring structure connected to the jack. The force transmission piece is pushed by the jack, so that the cable clamp applies tangential force opposite to the twisting direction to the steel strand inhaul cable, whether the steel strand inhaul cable is loosened or not is observed, and a corresponding force value is monitored through the pressure monitoring structure. Simulation monitoring of actual construction is carried out through the detection device, corresponding quality data of the steel strand inhaul cable are obtained, and field construction can be guided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a detection device and a detection method for steel strand cables. Background technique [0002] A common cable is a steel strand, and the steel strand is a steel product formed by twisting a plurality of steel wires. When the direction of the applied force is opposite to the twist direction of the steel strand, it is easy to cause multiple steel wires of the steel strand to loosen. [0003] The cable-membrane canopy system is a commonly used roof structure system in large public buildings such as stadiums, in which the membrane structure is connected by clamping steel strand cables through cable clamps. When the unbalanced force in the circumferential direction of the cable clamp reaches a certain value, and the direction of the force is opposite to the twist direction of the steel strand, it is easy to cause the multiple steel wires of the steel strand cable to loosen, and...
