Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a mold for coring an elastic modulus test block after high-temperature and high-pressure curing. Background Art

[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement concrete obtained by mixing cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. In order to ensure the quality of the project, it is necessary to test the elastic modulus of concrete. To test the elastic modulus, it is necessary to drill a concrete core of a certain size. At this time, a concrete drilling and coring machine is needed to sample the test blocks after high temperature and high pressure curing. At present, due to the high temperature of the concrete after curing, concrete residues splash when coring the test blocks, which can easily cause harm to nearby workers and affect their health. At the same time, the test block vibrates during drilling and coring, resulting in deviation in the position of the test block coring, which reduces the effect of drilling and coring by the drilling and coring machine, and further affects the detection structure of the elastic module.

[0003] For example, the utility model patent with publication number CN214502969U discloses a fixing device for coring a concrete test block, comprising a hollow frame and a buffer block, wherein an upper end of the hollow frame and the front and rear ends relative to the hollow part are penetrated with a placement groove, the lower end of the inner part of the placement groove is provided with a second electric push rod, the upper end of the second electric push rod is provided with a support plate, the inner side of the upper end of the support plate is fixedly connected with a connecting rod, the upper ends of the hollow frame are fixedly connected with adjustment frames, the upper end of the adjustment frame is penetrated with an adjustment groove, and the lower end of the inner part of the adjustment groove is provided with a second electric push rod. An electric push rod, wherein the upper end of the first electric push rod is fixedly connected with an adjustment plate, the upper end of the adjustment plate is fixedly connected with a support frame, an electric motor is penetrated through the middle of the upper end of the support frame, a motor shaft extends from the lower end of the motor and a drilling tool is fixedly connected to the lower end of the motor shaft. When coring a test block, the device splashes concrete residues, which can easily cause harm to nearby workers and affect their health. At the same time, when drilling and coring, the test block vibrates, resulting in a deviation in the position of the test block coring, reducing the effect of drilling and coring by the coring machine, and further affecting the detection structure of the elastic module.
