Abstract

The invention discloses an auxiliary device for vibration wire type strainometer installation. The auxiliary device for the vibration wire type strainometer installation includes a concrete outer housing, a positioning chip and a gradienter are arranged on the concrete outer housing, a groove is formed in the middle of the concrete outer housing, a vibration wire type strainometer support is mounted in the groove through a horizontal inclination angle adjustment device and a vertical inclination angle adjustment device, convex ears are respectively arranged at the four corners of the upper part and the lower part of the concrete outer housing, and positioning holes are formed in the convex ears. 8 steel strands penetrate through the positioning holes, thus the auxiliary device is fixed inthe inner part of a to-be-tested structural steel reinforcement cage, the installation angle of a vibration wire type strainometer is adjusted through the horizontal inclination angle adjustment device and the vertical inclination angle adjustment device, the auxiliary device has the characteristic that installation is convenient, and the rate of survival and the installation precision of the vibration wire type strainometer can be effectively improved.

Description

Technical field: [0001] The invention relates to an auxiliary device for the installation of vibrating wire strain gauges, which is suitable for the auxiliary installation of vibrating wire strain gauges during the construction of various civil engineering structures such as bridges and buildings. Background technique: [0002] Stress-strain testing is a commonly used test method for engineering structures or structural components in the process of testing, construction and monitoring, and is an important means to evaluate the safety of structures or components. Civil engineering structures are usually high-order statically indeterminate structural systems, and internal force transfer and redistribution will occur after damage occurs. Therefore, monitoring the stress changes in key parts is helpful to discover structural damage. In addition, the structural temperature field has a great influence on the deformation and strain of the structure, which must be considered in calc...
