Description

Fixing and protecting device for outdoor temperature and strain sensor

Technical Field

The utility model relates to the field of building structure health monitoring, in particular to a fixing and protecting device of an outdoor temperature and strain sensor.

Background

The health monitoring of the building structure is to monitor the stress, deformation, vibration and other indexes (wind environment, temperature and humidity and the like) of the key position of the building structure in real time by adopting the mature sensor equipment technology at present, and obtain the safety reliability index of the building structure by an analysis means. At present, a building taking a reinforced concrete structure as a main body is the most common building form in China, the internal stress level of the reinforced concrete structure is an important index for monitoring structural health in the construction process, and a vibrating wire type strain sensor is generally adopted when the internal stress of the reinforced concrete structure is monitored, a vibrating wire type strain sensor method is to stretch a steel wire with a certain length between two mounting blocks, the mounting blocks are fixed on the surface of the structure, and the change of the tension of the steel wire in the vibrating wire type strain sensor is caused after the structure is deformed, so that the change of the natural frequency of the steel wire is caused. However, when the vibrating wire type strain sensor is applied to monitoring the internal stress level of a concrete structure, the internal steel wire thermal expansion coefficient is different from the thermal expansion coefficient of a concrete material, and the two steel wires cannot expand with heat and contract with cold together, so that when the internal stress of the concrete structure is not changed and the temperature changes, the vibrating wire expands with heat and contracts with cold due to the temperature effect, and further the measurement frequency and the conversion strain are deviated and error. Currently, the main solution to this problem is to correct the strain measurement value by performing temperature correction, but there is generally a large error in performing temperature correction. Based on the above problems, it is proposed to consider the influence of the temperature action in a manner of adopting a freely telescopic strain sensor (temperature plate) provided in the same condition, and a fixing and mounting structure is required to fix and protect the temperature plate.

However, in actual use, the sensor cannot be well protected due to the weather variation and the influence of external factors, and the sensor is installed in a ground insertion mode, so that the sensor has a narrow application range and is not suitable for a building with high hardness. Based on the above defects, there is a need for a monitoring device mounting structure that is simple in structure, convenient to install and detach, and capable of avoiding the monitoring device from being damaged by the external environment, and suitable for various types of building bodies.
