Background technology
Engineering structure with use time growth can lead to aging because being existed using the change of function, construction quality
Problem and suffer from the reasons such as natural disaster to need to take Reinforcement.Traditional reinforcement means mainly has：Section-increased method,
Reinforced with external steel encased, external strengthening method by bonding steel plate, prestressing, setting support method for strengthening, crack repairing method and injection are mixed
Solidifying soil method for strengthening etc..Compared with traditional method for strengthening, carbon fiber composite material reinforced method has that intensity is high, construction convenient and efficient,
The advantages of resistance to chemical attack is excellent, the suitability is good, therefore, is widely applied.Although carbon fibre composite has
Very high intensity, but elastic modelling quantity is relatively low, and the performance of its intensity is to be deformed into cost, thus its high intensity hardly results in and fills
Distribution is waved, and pre-stressed carbon fiber is reinforced and can be solved this problem well.
With the development of China's prestressing technique, pre-stressed carbon fiber beaverboard anchorage has obtained pushing away in a large number in construction
Extensively, the Mechanics Performance Testing also extremely people's concern therefore to anchorage.Increasingly sophisticated plus its service condition, rely on single at present
Pure static tension, relaxation test can not do the test of a reasonable benefit/risk to the service life of Anchor Cable Anchorage.Must divide
The fatigue behaviour of analysis pre-stressed carbon fiber beaverboard anchorage, predicts its safe operating life.Therefore it is sought after a kind of carbon beaverboard anchorage
The testing stand of mechanics properties testing.
