Description

Technical Field

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

[0002] As a fundamental element in modern construction, concrete components are used across a wide range of projects. These components are made by mixing cement, sand, gravel, and other raw materials in a specific proportion and then undergoing processes such as casting, vibration, and curing. They possess excellent compressive strength and durability. In building structures, concrete components perform multiple functions, including support, load-bearing, and enclosure, and are crucial for ensuring building safety and stability. With the continuous advancement of construction technology, the types and forms of concrete components are becoming increasingly diverse, including prefabricated and cast-in-place components, meeting diverse project needs.

[0003] Modern engineering has developed a variety of specialized devices for testing the strength of concrete components. These devices employ non-destructive or minimally destructive testing methods to accurately assess the mechanical properties of concrete components, including compression, tension, and flexure. For example, techniques such as rebound, ultrasonic, and core drilling are employed to test the strength of concrete components. These devices not only improve testing efficiency and accuracy but also minimize damage to the components themselves. Furthermore, with the advancement of intelligent technologies, concrete component strength testing equipment is becoming increasingly automated and intelligent, providing strong support for quality control and safety assessment in construction projects.

[0004] Patent document CN220251639U discloses a precast concrete component strength testing device, comprising: a testing device body, a hydraulic cylinder, a testing platform, and a multi-degree clamp assembly. The utility model rotates the rotary rod, and the threaded rod rotates accordingly. Under the action of the base, the threaded rod rotates forward. Under the action of the bearing sleeve, the threaded rod pushes the clamping block forward and rotates forward until it is close to the precast concrete component. The corresponding number of clamping blocks is selected according to the shape of the precast concrete component and screwed in. This allows various precast concrete components to be clamped for transverse hardness testing. Then, by moving the hydraulic cylinder downward to contact the precast concrete component, the precast concrete component can be subjected to longitudinal hardness testing. Multi-degree and multi-directional clamping improves the applicability of component shapes, allowing for rapid hardness testing of all components. The clamping method is simple and easy to understand, and is more practical.

[0005] As in the prior art of the aforementioned patent, using a pressure plate to compress precast concrete parts is an essential step in the quality inspection process, aiming to accurately assess the precast concrete parts' compressive strength. However, this critical step inevitably produces some side effects: small amounts of concrete debris and other types of impurities can be scattered during the compression process and adhere to the surface of the inspection table. If these residues are not promptly cleaned, they will not only affect the cleanliness of the inspection table, but may also become interference factors during the next inspection, adversely affecting the accuracy of the test results.
