A production process for precast concrete components for carbon dioxide curing
The present invention discloses a production process for precast concrete components for carbon dioxide curing, comprising the following steps: assembling a hollow frame mold and a complementary mold to form a mold platform plane or a combined mold with an internal mold cavity; injecting mixed concrete into the complete mold cavity or onto the mold platform; curing at room temperature and 100% humidity for a certain period of time, removing the complementary mold to expose the hollowed-out area of the hollow frame mold on the surface of the concrete test block; placing the concrete test block and the hollow frame mold in a carbon dioxide curing apparatus for carbonization curing until the concrete test block reaches the demolding strength, and then removing the hollow frame mold from the surface of the concrete test block. The present invention utilizes a step-by-step demolding method, which allows the component surface to be fully exposed by removing the complementary mold before reaching the demolding strength, allowing the component to dry and fully contact with carbon dioxide. This advances the carbon dioxide curing operation from after demolding to before demolding, making the carbon dioxide curing process practical for production.

The invention discloses a linear pre-tensioning prestress double-T-beam movable formwork configuration system and method.The linear pre-tensioning prestress double-T-beam movable formwork configuration system comprises a concrete fixing pedestal, a double-T-beam formwork assembly and tensioning assemblies, and the tensioning assemblies comprise the left side tensioning assembly, the right side tensioning assembly and a plurality of steel strands; the multiple steel strands are arranged in parallel and sequentially penetrate through the multiple double-T-beam formwork assemblies along the straight line, meanwhile, the two ends of the multiple steel strands are connected with the left side tensioning assembly and the right side tensioning assembly correspondingly for tensioning or releasing, the linear steel strands are completely adopted, tensioning construction is convenient, bending devices and the like are not used for the linear steel strands, accessory materials are saved, and the construction efficiency is improved. Meanwhile, stress concentration of the steel strands can be avoided, and construction is safer.
