Concrete prefabricating mold based on mortise and tenon joint structure principle and demolding device

Abstract

The invention discloses a concrete prefabricated formwork based on a mortise and tenon joint structure principle and a demolding device. The mold is composed of a sample preparation device and a telescopic device. The sample preparation device comprises a slide rail inner attached bottom plate, a side edge concave slide rail vertical part, an outer attached hanging ring, a central partition plate and an upper attached hanging ring type drawing baffle plate; the telescopic device comprises a telescopic rope type rotating wheel, a rope inlet hole, a rope outlet hole, a rotating wheel handle, a mouth-reserved symmetrical core-through tubular column, a support, a lifting baffle rope, a fixing short rod and a rotating wheel small hole. During sample preparation, the mold is assembled, after pouring and maintenance work, the telescopic rope type rotating wheel is rotated to lift the two side edge inwards-concave sliding rail vertical plates, the two side edge inwards-concave sliding rail vertical plates are lifted upwards and fixed after reaching the designated position, and then demolding is manually completed. According to the invention, the tenon-and-mortise structure principle is utilized, external force confining is not needed, the device is firmly assembled together, the concrete test block can be effectively demoulded, the corner damage of the test sample is effectively reduced, no power supply is consumed, and the device is energy-saving and environment-friendly.
