AI Technical Summary
Existing concrete pressure testing devices only have one shape of pressure end, which limits the pressure test to one pressure range and cannot adapt to concrete test blocks of different shapes.
A concrete specimen pressure testing device was designed, which includes a main end and a dispersed end. The dispersed end can be adjusted by combining a guide convex plate and a mounting screw hole, thereby expanding the pressure area to adapt to the pressure requirements of different concrete specimens.
It realizes multi-interval pressure testing of different concrete test blocks, and improves the adaptability and accuracy of pressure testing.
