Background
The post-cast strip is a concrete strip reserved at corresponding positions of a foundation slab, a wall and a beam according to design or construction specification requirements in order to prevent harmful cracks possibly generated due to uneven self shrinkage or uneven settlement of a cast-in-situ reinforced concrete structure in building construction. The post-pouring belt temporarily divides the structure into a plurality of parts, the construction joint concrete is poured and smashed after a plurality of times after the internal contraction of the components, and the structure is connected into an integral zone. When the casting time of the post-cast strip is low, casting cement or concrete doped with a small amount of aluminum powder in cement can be used, the strength grade of the concrete is one level higher than that of a member, and cracks between new and old concrete are prevented from forming weak parts. The position for setting the post-cast strip also needs to consider consumption factors of different measures such as templates.
The post-pouring belt is arranged in construction, and a seam with the width of 700-1000 mm is arranged every 30-40 m in a long building, and reinforcing steel bars in the seam adopt a lap joint or straight-through bending method. After the post-cast strip is reserved, the concrete can shrink freely in the construction process, so that shrinkage stress is greatly reduced. The tensile strength of concrete can be used mostly to resist temperature stresses, increasing the ability of the structure to resist temperature changes. Post-cast strip retention times are typically no less than one month, during which shrinkage deformation can be completed by 30% to 40%. At present, the basement post-cast strip of the building construction site is generally exposed outside before earthwork backfilling, the exposed steel bars of the post-cast strip are corroded seriously, the bottom area is filled with soil and garbage, the later cleaning difficulty is high, the leakage risk of the post-cast strip is increased, the earthwork is not backfilled, the surrounding foundation pit is deeper and ponding is serious, the potential safety hazard is high, the surrounding roads of the building cannot harden at a later time, the site is messy, and the construction of the site safety civilization is not facilitated.
