Preferred: the reinforced mesh is b4@50&50 model, increases netted density, increases toughness.
Preferred: the cast-in-place concrete layer and UHPC precoated plate layer wind up reinforcing bar, the casting of web member reinforcing bar integrally,
Preferred: the UHPC precoated plate layer thickness is only the half of normal concrete preformed layer thickness.
Preferred: the steel bar girder section is triangle, the wavy arrangement of web member reinforcing bar.
Preferred: 20X20 chamfered is done in top surface on side one side of something of the UHPC precoated plate layer, and 5X5 chamfering is done in lower surface Processing.Lower bevel install at the scene it is in place after, with polymer crack resist at mortar jointing, levelling.Effectively preventing superimposed sheet plate is low It cracks and practical and attractive.
Compared with prior art, the utility model has the beneficial effects that the utility model is that a kind of UHPC very-high performance is mixed Coagulating soil steel bar girder laminated floor slab, the superelevation durability of UHPC material itself and the mechanical property of superelevation and its has economy Property it is good, easy for construction and without temporary support, can be shortened the advantages that construction period, good integrity, can effectively solve floor piece Problem is significant in building trade field.
