Problems solved by technology

[0002] Concrete strain gauges are generally embedded strain gauges, which are buried in concrete structures such as foundation piles, or tied to steel bars, and are used to measure the strain and stress of concrete and steel bars inside the structure. They are mainly used in bridges, roads, and railways. Stress and strain measurement inside concrete structures such as subways, tunnels, dams, foundation piles, etc., because they are used in different projects, the environment for stress and strain measurement will also be different, which affects the accuracy and reliability of stress and strain monitoring data One of the bigger factors is the temperature of the measurement environment. Different temperatures will make the data measured under the same stress condition deviate greatly, so that people cannot accurately obtain the stress-strain data inside the concrete structure, which affects people's understanding of the inside of the concrete structure. The judgment of stress, which leads to the occurrence of engineering accidents and the losses caused are huge

Embodiment Construction

[0008] refer to figure 1 , a concrete strain gauge, which includes a casing 1, a temperature sensor 2, a strain sensor 3, and a cable 4, the casing 1 is provided with a temperature sensor 2, a strain sensor 3, and the middle of the casing 1 is provided with a cable 4, and the cable 4 and the temperature sensor 2 , The strain sensor 3 is connected.

[0009] The present invention adds a temperature sensor inside the ordinary concrete strain gauge, and the temperature sensor and the strain sensor transmit the measured data to the outside through the cable, because a temperature sensor is set, so that the stress inside the concrete structure can be measured The strain data is measured at the same time as the temperature data. After the two data are transmitted to the technicians, the technicians compensate the stress and strain data according to different temperatures, thereby improving the accuracy of the stress and strain monitoring data inside the concrete structure. and relia...

Abstract

The invention discloses a concrete strain gauge, relating to the stress strain measurement device inside the construction structure. The concrete strain gauge comprises a shell, a temperature sensor, a strain sensor, and a cable. A temperature sensor and a strain sensor are arranged inside the housing. The cable is arranged in the middle of the shell, and the cable is connected to the temperature sensor and the strain sensor. The concrete strain gauge adds the temperature sensor in the common concrete strain gauge, which is convenient for the temperature compensation, improves the accuracy and reliability of the monitored data and prevents the engineering accidents caused by the environment factors.
