Description
Technical Field
[0001] The utility model relates to the technical field of detection equipment, in particular to a demoulding fixture for concrete anti-seepage performance experiments. Background Art
[0002] When conducting a concrete impermeability test, the concrete needs to be formed in a cylindrical mold and then tested. After the test, the concrete needs to be separated from the inner wall of the cylindrical mold and taken out so that the mold can be used for the next set of experiments. Demolding requires a demolding machine to raise the lower edge of the cylindrical mold, and then use downward pressure to poke the concrete out of the mold. The existing method of raising the mold is to use several pads. After positioning the mold, the mold with concrete is placed on it and then carefully adjusted to prevent the edge of the pad from exceeding the edge of the inner circumference of the mold to affect the demolding work. This process takes a lot of time and needs to be improved urgently. Utility Model Content
