Classification of prestressing technology
1. Different classification according to prestressing method ①The first method: On the pedestal or steel form, the steel bars are first tensioned and fixed with temporary fixtures, and then the concrete is poured. After the concrete reaches a certain strength, the prestressed tendons are loosened to make the concrete generate prestress. Suitable for prefabricated elements. ②Post-tensioning method: The components or structures are made first, and then the concrete is stretched after reaching a certain strength, so that the concrete generates pre-stress. Applies to cast-in-place components.
2. According to the different bonding methods: ①No bonding: Refers to the prestressed concrete in which the prestressed steel strand is free to expand and deform and does not bond with the surrounding concrete. The full length of the unbonded prestressed steel strand is coated with grease and protected by a plastic tube. ②With bonding: It refers to the prestressed concrete in which the prestressed steel strand is completely bonded and wrapped by the surrounding concrete or cement paste. Both pre-tensioned prestressed concrete and post-tensioned prestressed concrete with pre-set channels pierced and grouted belong to this category. ③Slow bonding: It means that the prestressed tendons can be stretched and deformed freely during the construction stage, and do not bond with the surrounding retarding adhesive, but the prestressing tendons are bonded with the surrounding concrete through the cured retarding adhesive within a predetermined period after the construction is completed. The prestressed tendons and the surrounding concrete form one body and work together to achieve a sticky effect.
3. Classification by prestressing degree ①Fully prestressed structure: Prestressed concrete that does not allow tensile stress at the tensile edge under full service load. Applicable to the requirement that the concrete is not open cracked structure. Partially prestressed structure: Prestressed concrete that allows certain tensile stress or cracks to occur at the tensile edge under full service load. ②Partially prestressed structure: Prestressed concrete that allows certain tensile stress or cracks to occur at the tensile edge under full service load.
