Domain, the staged reinforcing strip system and construction method of specially a kind of continuous concreting.
Background technology
In recent years, with the diversified development of building trade, Structural Design is more and more novel, overlength knot in city
The building of structure, large chassis multi-tower type structure or body irregular structure continues to bring out.Especially there is particular/special requirement to underground waterproof
Overlarge area hypogee emergence.Most of structure design has Construction Later Casting Zone, and the contraction to solve concrete is opened
Split problem.
But percolating water easily occurs for post-cast strip position, and hidden danger is brought to the normal use of building.In main body construction
Indwelling time is longer, and curing water and construction rubbish are extremely serious to steel bar corrosion during this period, cleaning work before cast and at
Product protect difficulty larger.In construction, due to the dismounting of template, the beam slab of post-cast strip both sides becomes cantilever member, with design
Intention is disagreed.Under entirely, superstructure, place of arrival meets the disconnected beam of beam, meets the disconnected plate of plate, is brought very to construction for post-cast strip
It is mostly inconvenient, influence construction speed.Before post-cast strip fills concrete, both sides concrete dabbing need to be constructed extremely difficult, and had
A little structural concretes and post-cast strip concreting time interval several months, the adhesion strength of New-old concrete it is difficult to ensure that, and by
In pouring the time difference, cause the drying shrinkage of the concrete of these structures is most of to be completed before post-cast strip fills.Therefore, post-cast strip
The drying shrinkage of concrete easily generates crack in the junction of New-old concrete.The original intention that Construction Later Casting Zone is arranged is to prevent concrete
The generation in crack, then pours that tape handling is bad but artificially to cause two through cracks at every post-cast strip, causes leak.
