Post-cast strip pre-sealing structure

Technical Field

The utility model relates to a construction field, in particular to post-cast strip enclosed construction in advance.

Background

In the field of building construction engineering, a post-cast strip is a temporary construction joint which is reserved at a corresponding position of a foundation slab, a wall, a beam and the like where concrete is firstly poured in order to prevent a cast-in-place reinforced concrete structure from possibly generating harmful cracks due to nonuniform self shrinkage or nonuniform settlement, and concrete needs to be poured into the construction joint after a period of time.

At present, in the sealing construction of the telescopic post-cast strip of the large-scale ground reservoir, the construction is carried out after the age of concrete on two sides of the post-cast strip reaches 60-90 days in the traditional method, and for the post-cast strip which is settled, the construction is carried out after the main body of the high-rise structure is capped and the settlement is stable, and then the construction of working procedures such as roof covering, greening, municipal administration and the like can be carried out. According to the method, the roof of the ground reservoir can be poured after the stretching deformation, the settling deformation and the like are basically finished, and the landscape earthing cannot be inserted in advance before the later pouring belt is not closed, so that the construction is long in time consumption and much in time consumption, and in the current time period with the emphasis on time cost, the construction period is long and the efficiency is low.
