Description

Technical Field

[0001] This utility model belongs to the field of building engineering testing, and in particular relates to a concrete strength testing device. Background Technology

[0002] In modern construction engineering, concrete is one of the most important building materials. The strength of concrete directly affects the structural safety and service life of a building. Therefore, accurate and rapid testing of concrete strength is crucial for ensuring the quality of construction projects.

Residual concrete on the equipment makes it difficult to conduct subsequent tests, and uneven stress may occur during testing. In addition, residual concrete can corrode the equipment and reduce its service life. Therefore, we propose a concrete strength testing device. Utility Model Content

This gear then moves a rack, which slides within a slide rail. The rack's movement moves a U-shaped plate, which in turn moves the clamping plate, thus clamping the concrete. This design improves testing accuracy, prevents concrete from shaking and affecting results, and prevents accidental spillage that could injure operators, thereby enhancing safety.

[0024] 2. This utility model incorporates a scraper. When the worm gear rotates, it drives the worm wheel to rotate, which in turn drives the threaded tube to rotate. As the threaded tube rotates, it moves the threaded rod, which in turn moves the fixing ring and the fixing rod. When the fixing rod moves, it tilts the placement platform, pouring the concrete into the collection box. Simultaneously, the scraper can be moved, thus protecting the equipment, preventing residual concrete from affecting subsequent tests, avoiding uneven stress, and preventing residual concrete from corroding the equipment and reducing its service life.
