Construction Technology of Pretension Prestressed Reinforced Concrete Structure of Multi-storey Logistics Warehouse

At present, there is a problem of too much prestress loss in the construction of multi-layer logistics warehouses in China. To meet the quality requirements of the project, this paper puts forward the research on the construction technology of pretension prestressed reinforced concrete structure of multi-layer logistics warehouse. The loss of prestress in the construction process can be effectively controlled by incorporating pre-tensioning technology into the construction process, placing prestressed tendons, and tensioning operations. Taking a logistics warehouse construction project as the construction object, using the construction technology designed in this paper to construct, the experiment proves that the construction technology of the pretension prestressed reinforced concrete structure of the multi-layer logistics warehouse proposed in this paper can effectively reduce the prestress loss caused by the instability of the construction structure, and can effectively improve the construction quality of the multi-layer logistics warehouse. This shows that the application and practice of pretension prestressing technology in the construction process of reinforced concrete structures has a positive reference significance, which can meet the needs of green engineering such as energy saving and emission reduction, and also provide a positive reference value for the construction technology of multi-layer logistics warehouse.
