[0002] In construction projects, it is usually necessary to test the performance of concrete at regular intervals. The method is to cast a batch of cubic concrete test blocks of specified sizes, and use a concrete press to squeeze these concrete test blocks until the test blocks are broken and various data values ​​are obtained. A concrete press is a press that is mainly used to test the compressive strength of test blocks of building materials such as concrete, cement, high-strength bricks, and refractory materials. It can also be used to test the compressive strength of other non-metallic materials.

[0003] At present, concrete pressure testing instruments have the following defects when in use: the debris generated after the concrete test block is broken will fly out of the working area and scatter on the ground, making it inconvenient to clean up, and may even cause harm and damage to surrounding workers and objects.

[0004] Therefore, in response to the above problems, we propose a test pressure device for concrete experiments. Utility Model Content
