AI Technical Summary
In existing technologies, irregularly shaped precast templates are difficult to reuse, resulting in template waste and poor concrete forming quality. This is particularly economical for small buildings and irregularly shaped multi-curved surface casting, and the casting accuracy of curved surfaces is low.
A bending concrete casting template including an elastic bending plate, a back plate, an adjusting screw, and a locking structure was designed. The template can be adjusted and reused by adjusting the extension and retraction of the adjusting screw to form a curved surface structure with a specific curvature.
This enables adjustable and reusable templates, improves concrete forming quality, reduces template waste and subsequent repair costs, and enhances economy and the accuracy of curved surface casting.
