Description

Positioning device for compressive strength test block

Technical Field

The utility model relates to the field of infrastructure building engineering tests, in particular to a positioning device for a compressive strength test block.

Background

The compressive strength of the concrete test block is not only an important index for evaluating the quality of the concrete, but also an important basis for controlling the quality of the concrete. The concrete test block can be used for checking the compliance of actual production and mixing ratio, and timely grasping the control conditions of production quality such as actual production mixing ratio, raw materials and mechanical equipment metering. Therefore, the strength of the concrete test block can directly reflect the quality of concrete, and provides a basis for adjusting the mixing ratio. In production practice, the test blocks under the same conditions are combined for checking and evaluating the strength of the solid concrete, and the real strength of the solid concrete can be accurately reflected. Therefore, in the construction engineering of China, each project must be equipped with standard curing rooms and test block compressive strength tests. The concrete compressive strength test method is definitely and in detail specified in the national standard of concrete physical and mechanical property test method standard (GB/T50081-2019). One of them is: the center of the test piece should be aligned with the center of the lower pressure plate of the testing machine. However, in actual operation, due to the reasons of operation and angle, the alignment cannot be performed quickly, time is wasted, and efficiency is reduced.
