Abstract

The invention discloses an automatic measuring instrument for concrete static compression elastic modulus, which comprises a horizontal bottom plate, an upper strain measurement component, a lower strain measurement component, a dial indicator and a digital display; plate and four vertical sliding rods, the specimen positioning plate is provided with a specimen positioning block, and the specimen positioning block is provided with a left positioning surface, a right positioning surface and a rear positioning surface; the four sliding rods are fixedly connected by the top plate at the top, The front end of the top plate is provided with a test piece entrance; the lower strain measurement component and the upper strain measurement component are symmetrically arranged between the two slide bars on the same side of the test piece positioning plate, and the front and rear ends of the lower strain measurement component and the upper strain measurement component slide respectively. Connect the slide bar, the lower strain measurement component and the upper strain measurement component are equipped with a measuring thimble mechanism; the dial indicator is located between the two measuring thimble mechanisms on the same side of the specimen positioning plate, and the digital display is electrically connected to the Two dial gauges; a reset mechanism is installed on the top plate.

Description

technical field [0001] The invention belongs to the technical field of concrete performance testing, and in particular relates to an automatic measuring instrument for concrete static compression elastic modulus. Background technique [0002] The elastic modulus of concrete is used to characterize the relationship between the stress and strain of concrete, which is a very important mechanical property of concrete. It is used to calculate the deformation of concrete structures, analyze the generation and development of concrete cracks, and calculate the temperature stress of mass concrete. When , the modulus of elasticity of concrete is an essential parameter. The test of concrete elastic modulus needs to meet the test requirements of the current national standard GB / T5008. At present, the most widely tested device for concrete elastic modulus on the market and in the laboratory is the TM-2 concrete elastic modulus tester designed and produced according to the national stand...
