Description

Technical Field

[0001] This utility model relates to the field of concrete strength testing technology, and more specifically, to a device for testing concrete strength. Background Technology

[0002] Concrete strength testing is a crucial aspect of quality control in building construction. It involves using scientific methods and specialized equipment to test the compressive, tensile, and flexural strength of concrete to ensure it meets design requirements and functional specifications. Concrete strength directly impacts the safety, durability, and service life of building structures; therefore, accurate strength testing is of paramount importance for ensuring building quality and preventing potential safety hazards.

[0003] A search revealed an existing patent (publication number: CN217901365U) that discloses a strength testing device for building concrete, including a concrete aggregate anti-splash component. The top of the housing has a through hole, and the inner wall of the housing has symmetrical grooves on both sides of the through hole. A slider is embedded and slidably connected inside the groove. In this invention, a concrete test block is placed on a concrete test block placement plate. An electric cylinder is activated, causing its output shaft to drive the support plate and sliders to slide downwards. The two sliders move the concrete test block placement plate, which is fixed to it, to contact the top of the support plate. The support plate is supported by a fixed column to increase its compressive strength. A cylinder drives a pressure plate and a pressure sensor to extend into the housing to contact the concrete test block, apply pressure, and test. Thus, the device is not affected by the splashing of test block fragments during the pressure application process. Furthermore, the groove at the bottom of the housing facilitates the discharge and cleaning of the concrete test block and the debris generated during the pressure application process into the slag collection box, thus improving the cleaning and collection of debris.

[0004] However, during use, the aforementioned device cannot simulate a real environment, and the fragments still scatter, making cleanup difficult. Furthermore, the device's complex structure involves the coordinated operation of multiple components, increasing manufacturing costs and maintenance difficulty, and potentially leading to cumbersome operation and reduced testing efficiency. Additionally, the placement and removal of test blocks are not convenient, easily resulting in jamming or inaccurate positioning, affecting testing accuracy. Utility Model Content
