compression shear testing machine
The compression shear machine is specially used to test the mechanical properties of finished plate rubber bearings for highway bridges.It can be used to test the compressive modulus of elasticity, shear modulus of elasticity,shear angle, ultimate compressive strength,friction coefficient, rotation angle and load test of basin rubber bearings of highway bridges.
Compression shear testing machine
Introduction
The compression shear machine adopts four column structure.The beam, base and upper and lower pressing plates are all made of integral cast steel.The rigid strength and structural stability of the frame are better than those of the two column structure, which is convenient for measuring the elastic deformation of the sample. it can be used for compression modulus test, shear modulus test, shear bond property,shear aging,friction coefficient, angle test, ultimatecompressive strength test and corner test.the structure, function, performance and main technical indicators of the testing machine meet the requirements of the following standards
