Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of concrete detection, specifically relates to a building concrete durability detection equipment. BACKGROUND

[0002] The durability of concrete refers to its ability to maintain structural integrity, performance and appearance under different environmental and usage conditions. Concrete is affected by various factors during use, such as climate, chemicals, mechanical stress, etc. These factors can cause changes in the performance and durability of concrete, and even damage. Therefore, the durability assessment of concrete is an important prerequisite for ensuring the long-term use of building structures.

[0003] The Chinese patent document with authorization announcement number CN221707091U discloses a building engineering concrete durability detection equipment. The test block is clamped and fixed by the clamping part, and then the test block is driven into the inside of the test mold by the moving assembly, until the test block contacts with the fixed base, and the sealing part seals the connection between the test block and the test mold, ensuring the sealing performance during the test.

[0004] However, in the prior art, when the detection equipment detects the durability of concrete through the penetration test, it is necessary to strictly control the size of the test block. If there is an error in the size of the test block, it cannot be placed in the test mold, or there is a large gap between the test block and the test mold, which can easily cause water to seep out from the periphery of the test piece. In addition, the top of the clamped test block is blocked, making it difficult for the detection personnel to fully observe the water seepage condition of the end surface of the test block. Therefore, a building concrete durability detection equipment is proposed. Utility model content
