Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, in particular to a concrete strength detection device. Background Technique

[0002] Concrete refers to the general term of engineering composite materials that cementitious materials bond aggregates into a whole. Usually, the term "concrete" refers to using cement as the cementitious material and sand and stone as aggregates. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. The strength grade of concrete divided by the standard compressive strength (using a cube with a side length of 150 mm as the standard specimen, cured for 28 days under standard curing conditions, and the cube compressive strength measured according to the standard test method with a 95% guarantee rate) is called the grade, which is divided into 19 grades: C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80, C85, C90, C95, C100.

[0003] In the patent of a concrete strength detection device with the authorization announcement number of CN218212396U, when the concrete strength detection device provided by the utility model is in use, the concrete block to be detected is placed on the detection table, and then the hydraulic cylinder is started to push the hydraulic rod downward, and then it is pushed against the top of the concrete block for compressive stress testing. During this period, the rotating disks on both sides are rotated, and then the clamping plates at the front end are pushed against the sides of the concrete block, making the test more stable and the test data more accurate;
