Description
Technical field
The present invention relates to a kind of cavity building roof technical field, more particularly to a kind of assembled cavity laminated floor slab construction party
Method.
Background technology
As China's economic construction is developed by leaps and bounds, reinforced concrete structure is extensively applied in industry and civil buildings,
And achieve good techno-economic effect.High level, large space and antidetonation etc. are required due to architectural, nearly ten years, mixed
Solidifying soil hollow-ribbed floor is used widely in China's architectural engineering.The form of hollow-ribbed floor mainly has two big class,
One class is Cast-in-situ Hollow-ribbed Concrete, and another kind of is the prefabricated Hollow-Ribbed Concrete Floor with cast-in-place combination.It is cast-in-place
The technology practice weekly notes of Hollow-Ribbed Concrete Floor are mainly by filling " internal model " among cast-in-place concrete.Internal model can be adopted
With hollow tube filler, casing, the cylinder that light solid may also be employed, block.The filled internal mold of hollow-ribbed floor is realized in addition
Integrated support structure is at this stage, and these components can be the cylinder of hollow tube filler, casing or light solid, block.But
It is that its purposes is identical, as just filler.Its construction is identical, is integrated support structure.Hollow-Ribbed Concrete Floor technology
