Several groups bolt hole is set on the connecting plate of the top plate.
The upper and lower L shaped plate structure is identical.
The concrete compression elastic modulus detection device of the utility model, using displacement principle of relativity by concrete compressed-bit
Transferization L shaped plate separates displacement relatively, to accurately measure concrete compression displacement using extensometer；By L shaped plate with
The bolt of connecting plate changes, and realizes different height of specimen and applies a kind of specification extensometer；Top plate and bottom plate large-size can be with
It is adapted to the concrete compressions elastic modulus detection such as cube, prism and cylinder.
L shaped plate is bolted on connecting plate, and L shaped plate and top are adjusted according to the height and position of bolt hole in installation
Plate or bottom distance between plates, to adapt to the measurement of different height test specimen elasticity modulus, meanwhile, guarantee is connected to L shaped plate in top plate and bottom plate
Horizontal position be fixed value, to adapt to extensometer minimum gauge length.
Extensometer collet is connect with L shaped plate horizontal segment, measures displacement, and extensometer is connect with acquisition system or other devices,
Form the concrete compression elastic modulus detection device of complete set.
Compared with prior art, advantage is the utility model concrete compression elastic modulus detection device：The measurement
Device makes full use of extensometer to measure and stretches the high feature of bit precisions, not only solves hydraulic servo universal testing machine and measures concrete
