AI Technical Summary
In the production of precast T-beams, the friction between the steel bars on the end mold of the diaphragm and the steel bar holes of the end mold causes the steel bars to bend and the concrete to fall off, affecting the production quality and efficiency. Existing non-scraping technologies such as grout-stopping strips have a narrow range of applications, and automated scraping operations are cumbersome and difficult to demold.
An auxiliary demolding device for the end mold of the cross diaphragm without chiseling was designed. It uses a servo electric cylinder as a power source, adjusts the force through the control component, and combines the PVA water-soluble film to cover the raised surface to achieve efficient demolding. The device can move freely through the moving component.
It improves demolding efficiency, simplifies the operation process, avoids stress concentration in the formwork, reduces manual intervention, and improves production efficiency and quality. The PVA water-soluble film can dissolve on its own at high temperatures without affecting the appearance quality of the concrete.
