Problems solved by technology

[0002] High-strength galvanized steel wires for bridges need to be subjected to high-frequency fatigue tests. The traditional loading and unloading method is to use 12 M16 bolts to lock the sample. It takes more than half an hour for the sample, which is laborious and time-consuming; at the same time, the traditional loading and unloading method is to use bolts to tighten the steel wire, which can easily damage the clamping part of the steel wire sample, so that the steel wire is fatigued at high frequency. During the process, the clamping end breaks and the test is invalid

Abstract

The invention relates to a bridge galvanized steel wire clamping device in a high frequency fatigue test. The clamping device comprises two opposite bases (1), two rivet barrels (2) and two anchors (3), wherein the rivet barrels (2) are arranged in the bases (1); the anchors (3) are arranged in the rivet barrels (2). The bridge galvanized steel wire clamping device in the high frequency fatigue test disclosed by the invention fundamentally solves a problem of time and labor consumption in loading and unloading processes when the high frequency fatigue test is carried out on a bridge galvanized steel wire; in the high frequency fatigue test, a clamped end of the steel wire is not easy to break, thus guaranteeing effectiveness of the test; the clamping device is simple in design and structure, and convenient to use.

Description

technical field [0001] The invention relates to a fixture for high-frequency fatigue test of galvanized steel wire used in bridges, which is mainly used to solve the laborious and time-consuming problems caused by traditional loading and unloading methods. It belongs to the field of testing technology. Background technique [0002] High-strength galvanized steel wires for bridges need to be subjected to high-frequency fatigue tests. The traditional loading and unloading method is to use 12 M16 bolts to lock the sample. It takes more than half an hour for the sample, which is laborious and time-consuming; at the same time, the traditional loading and unloading method is to use bolts to tighten the steel wire, which can easily damage the clamping part of the steel wire sample, so that the steel wire is fatigued at high frequency. During the process, the clamping end breaks and the test is invalid. Contents of the invention [0003] The object of the present invention is to...
