Description

Technical Field

[0002] In the process of construction, in order to test whether the compressive strength of the concrete used meets the requirements, a pressure testing machine is usually used to perform a compression test on the concrete column test block. When performing the compression test, it is necessary to apply a load to the concrete column test block, so a load applying device for a concrete column is required. The existing load applying device for a concrete column generally includes a workbench, a mounting frame, a punch and a support seat. The mounting frame and the support seat are both fixed on the upper surface of the workbench, and the punch is installed on the mounting frame so that the punch is located above the support seat. When in use, the concrete test block is placed on the support seat, and then the punch is controlled to slide downward and gradually apply pressure to the concrete test block, so that the compressive strength of the concrete test block can be tested, thereby reflecting the quality of the concrete used. According to a construction concrete test block pressure detection device with application number CN217786710U, it has the following features: under the action of the protective shell, it is beneficial to avoid the phenomenon of concrete fragments splashing and injuring the staff during the crushing of the concrete test block, and at the same time avoid the phenomenon of fragments flying to the ground and being difficult to clean. However, the equipment cannot perform compression tests when cleaning concrete debris because the cleaning process takes a long time, thus affecting the efficiency of continuous testing of concrete column test blocks.
