Between ~ 1/30, the width of the longitudinal and transverse beam rib among floorings is 10cm.
Compared with prior art, the utility model has the following beneficial effects: the ultra-high performance concrete bridge floor plate structure
Simply, construction is easy and convenient, material is novel and good mechanical properties, can be substantially reduced the sectional dimension of floorings, mitigates self weight,
The span for increasing floorings, saves the quantity of support construction, saving construction cost.Meanwhile utilizing the high intensity of UHPC, high tenacity and resistance to
The advantages that corrosion, significantly improves the durability of floorings, can effectively solve common reinforced concrete bridge deck plate cracking, part is broken
It splits or the problems such as burn into steel bar corrosion, obtains good mechanical property and economic benefit, there is very extensive application prospect.
Ultra-high performance concrete used in the utility model (UHPC) is to mix the mines such as a large amount of silicon ashes using fine sand as aggregate
Polymer blends 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 eliminates coarse aggregate (stone) compared with common concrete, be fines dense material and fibre reinforced materials it is compound and
At high performance concrete, compression strength and tensile strength are higher by than common concrete very much.Bridge is made using UHPC
Panel can reduce the sectional dimension of floorings, mitigate self weight, meanwhile, increase the span ability of floorings, reduces support construction
The quantity of meeting substructure, saving construction cost have good economic benefits, while the good service performance of UHPC can mention significantly
The service life of high floorings.
