Description
Technical field
The utility model is related to big flat concrete technical field of structures, more particularly to one kind based on after multi-level network format
Pour the super plane concrete structure of band.
Background technology
The type of distress in concrete mainly has：Settlement crack, deformation crack, comprehensive crack, expansion fissure and motional inertia
Crack.Wherein incidence of the concrete deformation crack in engineering reaches 80% or more, is the main original that concrete generates crack
Cause.And the producing cause of deformation crack is mainly that the deformation of concrete autogenous shrinkage, variation of ambient temperature and concrete itself are swollen
Bulging deformation is mainly the curing temperature for controlling concrete for the settling mode in crack is generated because of temperature change；And it is directed to coagulation
Crack caused by native self-deformation, settling mode mainly take Crack Resistance from material, change form of construction work, increase reinforcing bar
Dosage or setting post-cast strip.
According to existing concrete design specification, concrete structure is to avoid contraction fissure, needs that permanent expansion joint is arranged
And Construction Later Casting Zone, Construction Later Casting Zone are a kind of temporary construction seams, are the improving technologies at permanent expansion joint, are to prevent overlength from building
Build the effective measures for being deformed crack.Reinforcing bar at existing conventional rear pouring tape construction method post-cast strip is all continuous, and is mixed
The contraction distortion of Xtah Crude Clay structure cannot freely be discharged, when the length or width of concrete structure are more than certain size,
Deformation crack is inevitable, and therefore, the size of concrete structure nevertheless suffers from larger limitation.
Utility model content
The utility model provide it is a kind of the contraction or expansion of concrete structure can be made to deform adequately discharged, effectively
Avoid the super plane concrete structure based on multi-level network format post-cast strip of the deformation crack of concrete structure.
The technical issues of solution is：Existing routine post empiricism is only capable of improving to a certain extent because concrete itself becomes
Distress in concrete caused by shape, since the reinforcing bar at post-cast strip is continual, the contraction distortion of concrete structure cannot obtain
It freely discharges, significantly limits the size of concrete structure.
