Description

Technical Field

[0001] The invention relates to the technical field of concrete compression test tools, in particular to a material feeding and discharging device for full-automatic concrete compression test test blocks. Background Art

[0002] Concrete is primarily subjected to pressure in the structure, so its compressive strength index is the most important strength index. The compressive strength of concrete is related to many factors such as composition materials and construction methods. It is also affected by factors such as specimen size, loading method, loading speed, etc. Therefore, there must be a standardized strength measurement method and corresponding strength assessment standards.

[0003] At present, there are two types of concrete specimens used to determine the compressive strength of concrete in the world: cylinder and cube. my country stipulates that the compressive strength of concrete is measured with a cube specimen, and it is used as the basis for assessing the strength grade of concrete. It is stipulated that a cube with a side length of 150mm is used as a standard specimen, and it is maintained in humid air at a temperature of (20±2)℃ and a relative humidity of more than 95% for 28 days. The compressive strength measured according to the standard experimental method (no lubricant is applied to the surface of the specimen, and pressure is applied at a prescribed loading speed) is used as the compressive strength of the cube, recorded as fcu, in N / m㎡. The determination method of the compressive strength of the cube reflects the primary factors affecting the compressive strength of the cube.

[0004] At present, most quality inspection agencies still use personnel to carry concrete specimens during the concrete compressive strength test. One person takes a concrete specimen from the material turnover trolley, places it in the center of the press head, operates the control button, and the press head presses down to automatically perform the concrete compressive strength test. After the test is completed, the press head returns to its original position, and another person takes the concrete specimen from the other side of the press and places it on the waste turnover trolley. The disadvantages of this operation method are high labor intensity, low efficiency, and high cost. Summary of the invention
