Abstract
The invention provides a novel embedded type strain gauge and relates to a stress strain measurement device in a civil structure. The novel embedded type strain gauge comprises a shell, a temperature sensor, a strain force sensor and a cable. The shell is internally provided with the temperature sensor and the strain force sensor. The middle part of the shell is provided with the cable which is connected with the temperature sensor and the strain force sensor. According to the novel embedded type strain gauge, the temperature sensor is added into a common concrete strain gauge, temperature compensation is facilitated, the accuracy and reliability of monitoring data are raised, and an engineering accident caused by the influence of environmental temperature factors is avoided.
Description
Technical field:
The present invention relates to the stress-strain measurement device of civil structure inside, be specifically related to a kind of novel embedded strain gauge.
Background technology:
Concrete strain gauge is generally a kind of embedded strain gauge, namely be embedded in the xoncrete structures such as foundation pile, or be bound on reinforcing bar, for the strain of inside configuration concrete and reinforcing bar, stress measurement, be mainly used in bridge, highway, railway, subway, tunnel, dam, the stress-strain measurement of the xoncrete structure inside such as foundation pile, because be applied to different engineering, the environment of its stress-strain measurement also can be different, it is wherein the temperature of measurement environment for the accuracy of ess-strain Monitoring Data and the larger factor of reliability effect, the data deviation that different temperature can make identical stress condition record is larger, thus make people can accurately not obtain the stress-strain data of xoncrete structure inside, affect the judgement of people to the stress of xoncrete structure inside, cause the generation of engineering accident therefrom and the loss caused is huge.
Summary of the invention:
The object of this invention is to provide a kind of novel embedded strain gauge, its built-in temperature sensor, be convenient to carry out temperature compensation, improve accuracy and the reliability of Monitoring Data.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises shell, temperature sensor, adaptability to changes sensor, cable, temperature sensor, adaptability to changes sensor is provided with in shell, be provided with cable in the middle of shell, cable is connected with temperature sensor and adaptability to changes sensor.
The present invention adds a temperature sensor in common concrete strain gauge inside, temperature sensor and adaptability to changes sensor by measured data by cable transmission to outside, because be provided with a temperature sensor, make to record temperature data at that time at the stress-strain data recording Xtah Crude Clay structure inside simultaneously, after these two data are transferred to technician, technician carrys out counter stress strain data according to different temperature and compensates, thus improves accuracy and the reliability of the ess-strain Monitoring Data of Xtah Crude Clay structure inside.
The present invention it common concrete strain gauge inside add temperature sensor, be convenient to carry out temperature compensation, improve accuracy and the reliability of Monitoring Data, avoid the generation causing engineering accident because of the impact of environment temperature factor.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
With reference to Fig. 1, a kind of novel embedded strain gauge, it comprises shell 1, temperature sensor 2, adaptability to changes sensor 3, cable 4, is provided with temperature sensor 2, adaptability to changes sensor 3 in shell 1, be provided with cable 4 in the middle of shell 1, cable 4 is connected with temperature sensor 2, adaptability to changes sensor 3.
The present invention adds a temperature sensor in common concrete strain gauge inside, temperature sensor and adaptability to changes sensor by measured data by cable transmission to outside, because be provided with a temperature sensor, make to record temperature data at that time at the stress-strain data recording Xtah Crude Clay structure inside simultaneously, after these two data are transferred to technician, technician carrys out counter stress strain data according to different temperature and compensates, thus improves accuracy and the reliability of the ess-strain Monitoring Data of Xtah Crude Clay structure inside.
The present invention it common concrete strain gauge inside add temperature sensor, be convenient to carry out temperature compensation, improve accuracy and the reliability of Monitoring Data, avoid the generation causing engineering accident because of the impact of environment temperature factor.
