A kind of UHPC ultra-high performance concrete steel bar girder laminated floor slab
The utility model relates to concrete floor field, specially a kind of UHPC ultra-high performance concrete steel bar girder
Laminated floor slab.
The advanced degree of main member of the floor as building structure, form and technology for the quality of engineering, cost,
Duration has a significant impact.Currently, floor mainly has cast-in-situ reinforced concrete slab, concrete prefabricated board, profiled sheet-coagulation local soil type
It is several to close floor and superimposed sheet etc..Wherein, it though in-situ reinforced concrete slab has the advantages that good integrity, need to carry out a large amount of
Complicated Site Template engineering, reinforced bar engineering and concrete works, so that it is slow to bring speed of application, long in time limit, cost of labor
The deficiencies of height, construction quality is difficult to control, it is difficult to realize industrialized production, while also be unfavorable for energy conservation and environmental protection.Concrete is pre-
The problems such as although making sheet speed of application is fast, floor overall stiffness is poor, and earthquake is serious, and there are antiseepages, anti-leakage, seriously limits
It is applied.Although Profiled Steel Sheet and Concrete Composite Floor floor overall stiffness is big, formwork supporting plate is not needed, cost is high, die mould steel
Plate need to do fire prevention processing, and bottom surface out-of-flatness need to often do furred ceiling processing.Existing superimposed sheet has the disadvantage in that preformed layer and folds
The superposed surfaces closed between layer need to carry out stringent processing, and the overall performance after overlapping is difficult to ensure；Live reinforcing bar binding is cumbersome, applies
Work speed is slow；Prefabricated panel transport, the lifting of superimposed sheet are inconvenient, easily damaged；The production of prestressed concrete laminated floor slab is multiple
It is miscellaneous, and antiarch makes board bottom out-of-flatness.
