Abstract
The GRC formwork structural column adopts the factory-based vertical prefabrication production process, which can reduce the floor space, reduce the formwork loss, speed up the construction progress, promote the full decoration of the prefabricated building, and improve the efficiency of the assembly construction. major. In order to optimize the production process of prefabricated GRC formwork column, the overall stress system of GRC formwork structure is analyzed in the concrete pouring process, and the thickness of GRC formwork, the number of steel hoops and the GRC mode are considered. The influence of the shell cross-section size on the mechanical properties. The research results can provide reference for the optimization and design of prefabricated GRC formwork column production process.
Highlights
In recent years, the new prefabricated concrete industrial building has been in a high-speed development period under the active promotion of the government with its green environmental protection, energy conservation and consumption reduction, high construction efficiency, short construction cycle, easy to ensure the quality of factory operations and other characteristics.The traditional GRC material is easy to crack, which would reduce the bearing capacity and durability of the material, and seriously threaten the safety of people 's lives and property
In order to optimize the production process of prefabricated GRC components and improve the production efficiency of GRC components, the crack resistance of GRC materials was studied experimentally, and the finite element model of the whole force system of GRC shell structure column was established and analyzed, which provided a reference for the optimization and design of the production process of prefabricated GRC shell structure column
Due to the construction of cement concrete materials, the self-deformation problem and structural limitation of cementitious materials, the GRC materials are easy to crack in the environment with large temperature and humidity changing
