Abstract

The invention relates to a device for fixing a surface strain gauge base on the surface of a steel structure. The device is of a door-shaped structure consisting of a transverse base fixing screw, a vertical base fixing screw, a transverse fixing screw of the surface strain gauge base, a screw nut with a washer, a slide block, a metal pad with a rubber pad, a base and a magnet. The device for fixing the surface strain gauge base on the surface of the steel structure can ensure that base distance meets the requirement on installing the surface strain gauge, avoids base sliding caused by human causes in a repeated adhesion or base welding process, reduces the intensity of monitoring personnel for installing the surface strain gauge, and has simple structure, convenient assembly and disassembly.

Description

technical field [0001] The invention relates to a device for fixing the base of a surface strain gauge used for engineering monitoring on the surface of a steel structure. Background technique [0002] At present, the main method for fixing the base of the surface strain gauge to the surface of the steel structure is to bond or weld the base to the surface of the steel structure. The bonding process is longer than welding, but the coordination of the base on the surface is stronger than welding during the bonding process. Whether it is a bonded base or a welded base, the base is directly or indirectly fixed by applying force by hand. This operation method not only brings inconvenience to the monitoring personnel who install the surface strain gauge on site, especially when installing the surface strain gauge when working at heights, but also affects the installation quality of the surface strain gauge base. Contents of the invention [0003] In order to solve the inconve...
