Abstract

The invention discloses a rigid auxiliary system for a concrete uniaxial compression test; the rigid auxiliary system is composed of four sets of rigid auxiliary devices, and the four sets of rigid auxiliary devices are symmetrically distributed on the periphery of concrete test pieces, namely the four corners of a lower pressing plate of a press machine. Each set of rigid auxiliary device comprises a force transmission steel pipe, a belleville spring, a connecting plate, a guide steel column and a bolt. The device supports high-strength concrete test pieces of different sizes, has high applicability and operability, can adjust the rigidity of the auxiliary system according to the rigidity of the concrete test pieces, and can adjust the height of the rigid auxiliary system according to theconcrete test pieces of different sizes; the device can basically cover the uniaxial compressive stress-strain test work of existing concrete test pieces.

Description

Technical field

[0001] The invention belongs to the field of civil engineering, and relates to a rigid auxiliary system for a uniaxial compression test of concrete, in particular to a rigid auxiliary system for a uniaxial compression stress-strain test of high-strength concrete.Background technique

[0002] With the improvement and development of science and technology, high-strength concrete has been widely used in many engineering fields, and has gradually become an indispensable material in industrial and civil buildings. In the uniaxial compressive stress-strain test of ultra-high-strength concrete, it is more dangerous and difficult to measure the falling section of high-strength concrete compressive stress-strain, and the emergence of rigid element auxiliary system greatly reduces the difficulty of the test , The device has great scientific research value. Therefore, many universities have increased their research and development efforts to improve the manufacturing and working capa...
