Equipped with horizontal by regular reinforcement, the vertical regular reinforcement net or deformed bar net being compiled into, it is furnished in the beam rib by reinforcing bar and hoop
The framework of steel reinforcement that muscle is compiled into.
Further, above-mentioned ultra-high performance concrete precast hollow floorings overall thickness is the 1/25 of floorings length direction
Between ~ 1/30, the width of the longitudinal and transverse beam rib among floorings is 10cm.
Further, stringer rib, crossbeam rib and top plate and bottom plate inside above-mentioned ultra-high performance concrete precast hollow floorings
Chamfering is arranged in intersection area.
The construction method of band of the present invention ultra-high performance concrete precast hollow floorings of rib in length and breadth, it is characterised in that: institute
The ultra-high performance concrete precast hollow floorings for stating band rib in length and breadth include top plate and bottom plate and are located among top plate and bottom plate in length and breadth
The beam rib of intersection, intermediate longitudinal and transverse beam rib are crossed to form hollow structure, are furnished in the top plate and bottom plate horizontal, vertical by regular reinforcement
The regular reinforcement net or deformed bar net being compiled into, the beam rib are interior equipped with the framework of steel reinforcement being compiled by reinforcing bar and stirrup；
When production, horizontal, the vertical regular reinforcement net for being compiled into bottom plate by regular reinforcement first, or deformed bar net is set in bottom plate,
Then it arranges the hollow module between horizontal, longitudinal rib steel bar stress skeleton and cross, stringer, then passes through regular reinforcement cross, vertical volume
The regular reinforcement net of top plate is made, finally the regular reinforcement net of bottom plate or deformed bar net, in length and breadth the framework of steel reinforcement of rib and
It is poured ultra-high performance concrete between the regular reinforcement net of top plate, forms ultra-high performance concrete precast hollow bridge by maintenance
Panel.
Further, above-mentioned ultra-high performance concrete precast hollow floorings overall thickness is the 1/25 of floorings length direction
Between ~ 1/30, the width of the longitudinal and transverse beam rib among floorings is 10cm.
Compared with prior art, the invention has the following advantages: the ultra-high performance concrete floorings simple structure,
The easy and convenient, material of constructing is novel and good mechanical properties, can be substantially reduced the sectional dimension of floorings, mitigate self weight, increase
The span of floorings saves the quantity of support construction, saving construction cost.Meanwhile utilizing the high intensity of UHPC, high tenacity and corrosion-resistant
The advantages that significantly improve the durabilities of floorings, can effectively solve common reinforced concrete bridge deck plate cracking, partial fracture or
The problems such as burn into steel bar corrosion, obtains good mechanical property and economic benefit, has very extensive application prospect.
Ultra-high performance concrete (UHPC) used in the present invention is to mix the mineral such as a large amount of silicon ashes using fine sand as aggregate and mix
Close material, high efficiency water reducing agent and micro steel fiber, a kind of high intensity of formation, high-durability, high tenacity, closely knit concrete material
Material, compared with common concrete, eliminates coarse aggregate (stone), is that fines dense material is combined with fibre reinforced materials
High performance concrete, compression strength and tensile strength are higher by than common concrete very much.Bridge floor is made using UHPC
Plate can reduce the sectional dimension of floorings, mitigate self weight, meanwhile, increase the span ability of floorings, reduces support construction meeting
The quantity of substructure, saving construction cost have good economic benefits, while the good service performance of UHPC can greatly improve
The service life of floorings.
