Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete compression resistance detection, more particularly to a building concrete compression resistance detection device. BACKGROUND

[0002] Concrete is an essential material in modern construction projects, and compressive strength is the most important indicator of concrete. Sampling and testing are required when pouring concrete on the construction site, and compressive strength testing is performed in the laboratory.

[0003] After searching, the utility model with publication number CN219915181U discloses a building concrete compression resistance detection device, which comprises a base, both sides of the base are connected with handles at the top end, both ends of the horizontal symmetry axis of the inner wall of the base are fixedly connected with bearing blocks, both ends of the inner wall of the bearing block are connected with threaded shafts, the bottom of the threaded shaft is connected with a steering roller, the center of the inner wall of the base is connected with a placing frame, and the patent discloses a recycling frame and a placing plate structure. When the concrete is crushed, the fragments will fall into the placing plate and the recycling frame, which facilitates the cleaning of the detection personnel. By setting the blocking shell, the fragments flying around can be shielded, thereby avoiding the injury of the detection personnel. By setting the simple connection mode between the blocking shell and the recycling frame, the installation and disassembly steps of the blocking shell are more convenient and fast, thereby effectively solving the problems and deficiencies in the existing device.

[0004] However, the above-mentioned patent still has the following disadvantages: when the concrete test piece is placed on the placing frame during compression resistance detection, the middle part of the test piece is in a suspended state, which affects the accuracy of compression resistance detection. At the same time, it is not convenient to adjust the middle part of the test piece to be directly below the pressure plate, and it is not convenient to align the test piece. In addition, when taking out the waste in the placing plate and the recycling frame, the blocking shell needs to be removed, which is not convenient. Therefore, we propose a building concrete compression resistance detection device. UTILITY MODEL CONTENTS
