Description

Technical Field

[0001] The invention relates to the technical field of concrete performance detection, in particular to a sampling structure for concrete performance detection. Background Art

[0002] Concrete performance testing usually requires sampling and uses different structures for testing. The following are some common concrete sampling structures: cylindrical samples, cubic samples, plate samples, conical samples, and core samples. The above are just some common concrete sampling structures. The specific sampling method and structure selection should be determined according to the specific test requirements and relevant standards. When sampling, the operator holds a shovel in his hand. Before the concrete is loaded into the mold, it needs to be mixed evenly with a shovel to ensure that the concrete test block is representative. Then, the test block will be made by shoveling the concrete into the test mold with a shovel. After the concrete is placed in the test mold for two parts, the concrete is tamped 27 times with a tamping rod, and the tamping rod is kept vertical during tamping and must not be tilted. Then, half of the concrete is placed in the test mold again, and the concrete is tamped 27 times with a tamping rod again. Then, the air in the concrete is reduced. After the tamping is completed, a rubber hammer is needed to gently tap the test mold around until the hole left by the tamping rod disappears, so that the sample quality meets the standard, thereby removing the air inside the concrete. The steps are relatively cumbersome. For this reason, we propose a sampling structure for concrete performance testing. Summary of the invention
