Abstract

The invention discloses a multi-connected concrete anti-seepage test block demolding device and relates to the technical field of demolding. Due to the fact that existing demolding equipment can onlyconduct demolding on a test block each time, the efficiency is low. According to the scheme, the device comprises a base; a plurality of frames are fixed to the base; a demolding assembly is mounted on each frame; a plurality of demolding holes are formed in the base; each demolding assembly comprises a hydraulic jack, a top plate located between the hydraulic jack and the demolding hole, and an elastic part used for abutting against the hydraulic jack; each hydraulic jack comprises a cylinder block, an ejection rod, a pressure relief screw and a lever plug; a force application lever is detachably arranged on each lever plug in a penetrating mode; and each force application lever is provided with a connecting assembly. By arranging the multiple demolding assemblies on the base and mountingthe connecting assemblies which are used for connecting the adjacent force application levers and enabling the adjacent force application levers to shaking synchronously, all the hydraulic jacks canbe synchronously driven by an operator for demolding, and thus the demolding efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of demoulding, in particular to a demoulding device for multi-connected concrete anti-seepage test blocks. Background technique

[0002] In the detection of concrete impermeability performance, the concrete test block is put into the test mold for testing. After the completion, in order to reuse the test mold, the concrete test block must be removed from the test mold, and the unloaded test block needs to be dissected. Open to observe the penetration of internal moisture.

[0003] For the demoulding operation of the test block, the traditional method is generally to press the ejector pin against the concrete test block, and then hit the ejector bar with a hammer, or place two steel bars on the lower edge of the test mold, put it on the press, and use The press punches the test block for demoulding. The above-mentioned methods are time-consuming and labor-intensive, and easily deform the trial mold. [000...
