Description

Technical Field

[0001] The utility model relates to the field of concrete test block processing, in particular to a rapid disassembly device for concrete test blocks. Background Technique

[0002] A concrete test block is a concrete component used to measure the compressive strength of concrete and can reflect the construction quality of a concrete structure. When making a concrete test block, usually a cylindrical or cubic box is used to pour concrete into the box. Since there is a strong tension between the box and the concrete, it is very difficult to separate the box from the concrete after the concrete caking. The convenience of its disassembly needs to be considered. After retrieval, a rapid disassembly device for concrete test blocks disclosed in the application number CN202121965437.0 records that a pressure relief hole is arranged at the bottom of the box body, and the gasket hole is blocked by a gasket component. At the same time, lubricating oil is brushed on the inner wall of the box body. The blocking block is installed on the box body through a threaded hole, so that the concrete test block and the blocking block fix the gasket component. When the concrete test block needs to be disassembled, the blocking block is unscrewed, and the gasket component is pushed, so that air enters between the gasket component and the concrete test block, so that the concrete test block and the box body are separated from each other, so as to achieve the technical effect of quickly taking out the concrete test block from the box body. However, the above description still has the following defects in actual use: At present, it is not convenient to disassemble the concrete test block after caking, and the fixed structure lacks the ability of flexible adjustment, which increases the disassembly time of construction workers. Therefore, it is necessary to design a practical and flexible rapid disassembly device for concrete test blocks. Content of the Utility Model
