Problems solved by technology
[0003] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is: the existing measuring method is easy to destroy the sensor because the sensor is directly in contact with the stretched steel bar, the operation is dangerous, and it is greatly affected by human factors, and the accuracy is not high. The degree of automation is low. In addition, the fixture and the steel bar are prone to slippage during the stretching process, and the measured overall stretching length is also biased.

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] A non-contact steel bar deformation measuring device and measuring method, comprising the following steps:
[0022] ①Connect the pressure sensor to the tension device, and the computer is connected to the pressure sensor, the first acquisition card and the second acquisition card at the same time;
[0023] ②The first light screen is fixed on the left end of the steel bar. The first light screen is displaced with the stretching of the steel bar. The first charge-coupled device does not touch the steel bar. The position of the first light screen is dynamically collected by photography. The card collects the displacement information obtained by the first charge-coupled device;
[0024] ③The second light screen is fixed on the right end of the steel bar, and the second light screen is displaced with the stretching of the steel bar. The seco...

The invention discloses a non-contact type reinforcing steel bar deformation measurement device and a measurement method thereof. The measurement method comprises on the basis of two image sensors of charge-coupled devices, photographing tensile conditions of reinforcing steel bars in real time and synchronously sending tension sizes to a computer, recording the measured value of every component in real time through the computer, and performing real-time computing processing through self-designed software to obtain the change conditions of the tensile length of the reinforcing steel bars and the length of the reinforcing steel bars along with the tension. The on-contact type reinforcing steel bar deformation measurement device is simple in structure, can achieve reinforcing steel bar deformation measurement in a non-contact mode, is high in measurement accuracy, wide in measurement range, safe in operation and convenient to operate, saves manpower, and has a wide application prospect.
Description
technical field [0001] The invention relates to the detection and measurement technology of steel bars, in particular to a non-contact steel bar deformation measurement device and measurement method based on double charge coupled devices. Background technique [0002] With the development of my country's economic construction and the improvement of people's living standards, the inspection of existing buildings has gradually been put on the agenda. Whether there are defects in survey, design, construction, use, etc. of existing buildings, or they are affected by the weather Structural aging caused by chemical corrosion and chemical erosion will bring engineering hidden dangers and reduce the safety and durability of the structure. In order to determine whether the safety and durability of the structure meet the requirements, it is necessary to inspect and appraise the engineering structure, make a scientific evaluation of its reliability, and then carry out maintenance and re...
