Description

Technical Field

[0001] This application relates to the field of concrete mold technology, and more specifically to an internal mold suitable for flipping precast components. Background Technology

[0002] The assembly and disassembly of precast component molds is a critical process. After precasting, once the concrete strength reaches 75%, it is transferred to a storage yard for further curing until it reaches 100% strength, at which point the component is flipped over. At this point, the inner cavity of the precast component faces upwards, and the internal fixed-shape steel mold needs to be removed for reuse. Due to the irregular polygonal structure of the inner cavity, the increased adhesion of the concrete to the mold during strength gain, and the adverse effects of the fully fixed structure, existing technologies are labor-intensive, time-consuming, and inefficient in disassembling the inner cavity mold, and may also damage the precast concrete component.
