Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete components, and particularly relates to a device for detecting the strength of precast concrete. Background Art

[0002] Concrete: It refers to the general term of engineering composite materials in which the aggregate is cemented into a whole by a cementitious material. Generally, the term concrete refers to cement concrete, which uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water (which may contain additives and admixtures) in a certain proportion and obtained by stirring, also known as ordinary concrete. Precast concrete components are building components prefabricated in a factory with concrete as the basic material, including beams, slabs, columns and building decoration fittings, etc.

[0003] The patent authorization announcement number CN 220251639 U discloses a device for detecting the strength of precast concrete components, including: a detection device body, a hydraulic cylinder, a detection platform, and a multi-degree fixture assembly. The utility model rotates the rotating rod, and the threaded rod rotates accordingly. Under the action of the base, the threaded rod advances forward. Under the action of the bearing sleeve, the threaded rod pushes the clamping block forward until it is tightly attached to the precast concrete component. According to the shape of the precast concrete component, the corresponding number of clamping blocks are rotated in to clamp various different precast concrete components for transverse hardness testing. Then, the hydraulic cylinder moves down to contact the precast concrete component, and longitudinal hardness testing can be carried out on it. The multi-degree and multi-directional clamping can improve the applicability of the component shape, and rapid hardness detection can be carried out on it. The clamping method is simple and easy to understand, and the practicability is higher.
