Description

Technical Field

[0002] The post-cast strip is a temporary construction joint left at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications to prevent harmful cracks that may be caused by uneven shrinkage or settlement of the cast-in-place reinforced concrete structure during construction. The post-cast strip temporarily divides the structure into several parts, and after a certain period of time after the internal shrinkage of the component, concrete is poured in the construction joint to connect the structure into a whole.
