Description
Technical field
The utility model relates to canopy and its precast reinforced is poured after assembled architecture field of engineering technology more particularly to one kind
Concrete frame beam.
Background technique
Process of Housing Industrialization is carried forward vigorously in country and place in recent years.Wherein, Shanghai City requires the outer ring from 2016
Civil buildings are created within line should be all using assembled architecture, and Section of Outer Ring Line is in addition more than 50%；Section of Outer Ring Line is external from 2017
Increase year by year on the basis of 50%.Meanwhile to using concrete structural system build assembled architecture monomer pre-emulsion assembly rate into
It has gone and respective specified and has stepped up, since 2016, monomer pre-emulsion rate was not less than 40%.
With assembled architecture development and widely popularize, there is various technical problem, existing assembled rule
The reference way that model and atlas provide just seems awkward, the serious development for restricting assembled architecture technology.
Currently, canopy stress indulges muscle and is generally 8@100, distributing bar one when the after-pouring canopy design of cantilever span 1m
As be 8@200, canopy stress is indulged there are mainly three types of the connection types of muscle and precast reinforced concrete frame beam:
The first: setting a roof beam in place upper embedded bar mechanical sleeves in prefabricated frame, and then live formwork supporting plate, is mechanically connected stress steel
Muscle binds distributed structure reinforcing bar, casting concrete.
This way disadvantage: it is 8 100 that stress, which indulges muscle, more in prefabricated frame interior pre-buried reinforcing steel bar machinery sleeve of setting a roof beam in place, not only
It is costly, and prefabricated frame sets a roof beam in place production and later period canopy site operation is inconvenient.
Second: directly reserving canopy steel bar stress in precast frame beam sides, then live formwork supporting plate, binding distribution structure
Make reinforcing bar, casting concrete.
This way disadvantage: when prefabricated components are manufactured, mold periphery throws away one meter or so of reinforcing bar, not only causes die station
Upper a large amount of reinforcing bar accumulations, influence to produce；And since weight difference is very big inside and outside mold for canopy steel bar stress, necessarily cause by
Power reinforcing bar is tilted in die inside, reinforcing bar location difficulty；In addition, prefabricated frame is set a roof beam in place, outside throws away a large amount of canopy steel bar stresses, makes
It sets a roof beam in place at prefabricated frame in the inconvenience of transport, lifting and construction casting.
The third: prefabricated frame is set a roof beam in place normally to be produced in factory, after being transported to scene, rigging out, in precast frame beam sides
Drilling is implanted into canopy steel bar stress, and then live formwork supporting plate, binds distributed structure reinforcing bar, casting concrete.
This way disadvantage: 1. are connected using later period bar planting, and setting a roof beam in place to former component, that is, prefabricated frame, it is larger to damage；2. bar planting expense
Higher, construction quality is difficult to ensure；3. after the smooth side bar planting of prefabricated components, casting concrete, new-old concrete contact surface
It is bad to locate globality, stress weakness easy to form；4. atlas " concrete structure reinforcement construction " (13G311-1) page 196 is bright
True regulation this bar planting spreading floor way is not suitable for newly-increased cantilevered plate.
Therefore, canopy is poured after how providing one kind, it is easy for construction to realize, working efficiency is improved, is current this field skill
Art personnel technical problem urgently to be resolved.
