Fabricated Prefabricated stacking floor as substitute the floor of cast-in-place skyscraper, the novel product of roof system can reduce formwork,
The cumbersome process of form removal shortens the advantages such as construction period.
In order to ensure that laminated floor slab has enough attachment force with rear pouring concrete overlapping interlayer, need prefabricated overlapping building
Plate upper surface is configured to rough surface, and the area of rough surface is not preferably less than the 80% of faying face, the rough surface bumps depth of prefabricated board
No less than 4mm.Plucking or the processing of dabbing method can be used in rough surface, and dedicated concrete can also be used and undisguisedly expect medicament,
06SG439-1《Prestressed concrete laminated floor slab》It introduces, the molding of the methods of net-shaped drum can be used.But since component factory uses
Tool, technology etc. it is irregular (if any factory for prefabrication using broomings such as besom, steel brushes), not only inefficiency, quality
It being difficult to ensure, chemical treatment method cost is again higher, and current net-shaped drum mostly uses handle type, since handle is shorter, for
Big module component is inconvenient.
In addition, existing Prefabricated stacking floor usually needs to dispose hollow mold core above it in cast, in order to shape
At cassette ceiling, but since the concrete of cast is usually squeezed into below hollow mold core so that hollow mold core bear compared with
It is moved up after big buoyancy, it is difficult to it realizes and preferably positions, and the way of generally use being fixed on mold core on the arrangement of reinforcement of top, not only
Increase the amount of labour, and can frequently result in arrangement of reinforcement deformed damaged.
When Prefabricated stacking floor application is more and more wide, on urgent need will propose a kind of new Prefabricated stacking floor to meet
State demand.
