The load sensor is arranged between and the load applying device and the flexible energy storage device, and connected with the two devices; the displacement sensor is arranged on the surface of the test sample; the displacement and load sensors are connected with an automatic acquisition instrument. The tester for concrete creep test under compression of the utility model has a convenient operation, high precision of the automatic data gathering, low cost, and capability of maintaining the stability of the load in the test.
Description
Technical field
The utility model relates to a kind of concrete compression creep test tester.
Background technology
Concrete creep is to continue under the load action phenomenon that the distortion of xoncrete structure constantly increases in time.The creep loss of prestress that causes prestressed reinforced concrete construction or increase the amount of deflection of long-span beams or cause the excessive vertical differential deformation of (surpass) high building structure generation.So the test of concrete creep characteristic is necessary test.
The power of test of existing creep test apparatus is low, and load is adjusted complicated operation, adopts manual method collecting test data, is unfavorable for the test of this class testing time remaining several months of concrete creep even several years.
