Post-cast belt position 1. In order to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven temperature and shrinkage, in accordance with the requirements of the design or construction specifications, the slabs (including foundation floors), walls, and beams Temporary construction joints are left at corresponding positions to temporarily divide the structure into several parts. After the internal shrinkage of the components, the concrete for the construction joints is poured after a certain period of time to connect the structure into a whole.

Post-cast tape is an effective measure that can both solve settlement differences and reduce shrinkage stress, so it is widely used in engineering.

2. The position and distance of the post-casting tape are determined through design calculations. The width is usually 800 to 1200mm to facilitate construction and avoid stress concentration. When setting up the post-casting tape in areas with waterproofing requirements, it should be Consider the structure of the waterstop; the location where the post-casting zone is set up should also consider the different consumption factors of formwork and other measures; the strength level of the concrete in the post-casting zone must be one level higher than the original structure.
