Description
Technical Field
The utility model relates to a reinforcing bar calibration device among the reinforced concrete test, in particular to reinforcing bar corrosion device suitable for three kinds of magnetic sensor.
Background
Concrete materials are widely used in the field of civil engineering as the most widely used building materials today. The corrosion of steel bars is the main cause of the rust cracking failure of the concrete structure, and the rust expansion cracking of the reinforced concrete structure caused by the corrosion of the steel bars is the important cause of the reduction of the bearing capacity and the service performance of the structure. According to data published by the Chinese academy of sciences oceans: the corrosion loss of China is up to 1.6 trillion yuan each year, wherein the corrosion loss of infrastructure and buildings is up to 5000 trillion yuan.
Therefore, the long-term monitoring of the steel bars after the service of the reinforced concrete structure is very important, and if the steel bars are monitored and found in the early stage of structure cracking caused by rusting, the steel bars can be maintained in time, so that the service life of the structure can be greatly prolonged.
Based on the above background, the chinese patent grant publication No. CN109374726A, the grant publication date is 22/2/2019, the name is "a sensor and a system for monitoring nondestructive corrosion of steel bar in concrete based on magnetic field", the chinese patent grant publication No. CN208420791U, the grant publication date is 22/1/2019, the name is "a device for changing response of steel bar corrosion electromagnetic field", the chinese patent grant publication No. CN110646505A, the grant publication date is 1/3/2020, the name is "an external sensor and a test method for monitoring nondestructive corrosion of steel bar based on electromagnetic field principle", the name is "a chinese patent grant publication No. CN112034033A, the grant publication date is 12/4/2020, the name is" a separate sensor and a test method for monitoring non-uniform corrosion of steel bar based on magnetic field principle ", the patent provides a plurality of steel bar corrosion monitoring sensors based on the magnetic field principle and monitoring methods thereof, which are used for monitoring the steel bar corrosion condition in a reinforced concrete structure.
The corrosion monitoring sensor is generally used for in-situ monitoring of the steel bars. In the laboratory verification stage of the sensor, the corrosion steel bars need to be calibrated to determine the corrosion degree. The calibration process is as follows: after the sensor is used for reading the magnetic induction intensity of the steel bar to be measured, the steel bar is shifted and weighed, then the steel bar is manually electrified and corroded, after the manual corrosion is finished, the steel bar is weighed again, the sensor is used for measuring the magnetic induction intensity of the same position, and the steel bar corrosion degree is determined according to a formula after the weight and the magnetic induction intensity data before and after the steel bar corrosion are obtained. Therefore, the accuracy of the magnetic induction intensity greatly affects the calibration precision.
The following problems are encountered during steel bar calibration: firstly, the steel bar calibration needs higher precision, after the steel bar is shifted and weighed and corroded manually, the relative position of the steel bar and a sensor measuring head needs to be adjusted, so that the relative position of a steel bar measuring point and the measuring head is completely consistent with that before the steel bar measuring point and the measuring head are shifted, and magnetic induction reading can be carried out. The calibration is carried out by means of auxiliary tools such as a clamp, a graduated scale and the like, the operation difficulty is high, and the test precision is difficult to ensure; secondly, the sensors for calibration verification mainly have three types, namely an internal type, a separated type and an external type, and a single clamp cannot meet the calibration requirements of various types of sensors at the same time. Considering that the components of the separated and built-in sensors need to be embedded in concrete in the practical application process of the sensors, how to fix the embedded parts of the sensors in the laboratory stage needs to be considered to ensure that the embedded parts of the sensors are fixed; and thirdly, the laboratory comprises an engineering application stage, the diameters of the steel bars are different from 14mm to 20mm, and the calibration precision of the steel bars with different sizes cannot be guaranteed through manual correction.
A possible alternative is to use a steel bar clamp that can be weighed, the clamping device being able to perform both the functions of fixing and weighing the steel bar. Based on the theory, the Chinese patent application publication No. CN111392574A, with the application publication date of 2020, 7 and 10, is named as a steel bar clamp capable of weighing, mainly relates to material transfer and transportation, and can realize automatic clamping and weighing of steel bars. However, the patent is mainly used for transporting the steel bars in the construction stage of the building, and only reference is made for calibrating the steel bars in a laboratory.
Further, considering that the research on the durability of reinforced concrete is a popular field in recent years, many laboratories in China are conducting the research on corrosion of reinforced concrete. A calibration device suitable for all sizes of reinforcing steel bars provides a great deal of convenience for the test.
The above problems are urgently needed to be solved. Therefore, a steel bar calibration device suitable for steel bars of various sizes and sensors of various types is specially developed, the steel bar calibration device has very important engineering value, the efficiency of a steel bar corrosion test in a laboratory can be greatly improved, and the smooth research is helped.
