Abstract

公开一种非接触法混凝土形变测量仪标靶(以下简称标靶),用于非接触法测量混凝土试件的变形实验,在实验过程中,标靶必须稳固固定在标靶架上,为此,设计了小型的电涡流标靶,采用A3钢制造,直径为25毫米至35毫米厚度2毫米至4毫米,连接螺栓为M3,10毫米长。

Description

非接触法混凝土形变测量仪标靶
技术领域
本发明“一种非接触法混凝土形变测量仪标靶”是混凝土非接触测量试验的重要部件,作为电涡流传感器的目标靶,需要反射率高,材质轻便,变形小,性能稳定。(以下简称标靶) 
背景技术
随着混凝土品种的增多以及矿物掺合料外加剂的广泛应用,导致某些混凝土的早期收缩明显增大。混凝土早龄期(如前3d)的体积变形最为复杂,包括全部塑性沉降收缩,自生收缩,水泥水化的化学收缩以及混凝土表面失水产生的干燥收缩在早龄期也占较大比例。从而导致混凝土早期收缩变形的研究变得非常重要。 
发明内容
标靶,用于非接触法测量混凝土试件的变形实验,在实验过程中,新拌混凝土流动性比较大,标靶架必须稳定的竖立在混凝土中,为此标靶须轻便且电涡流效应大,故标靶采用A3钢制造,直径为25毫米至35毫米,厚度为2毫米至4毫米,安装螺柱M3,长度为10毫米。 
附图说明
图1是本发明的整体结构图。
