Description
Technical field
The present invention relates to bridge deck structure technical field, particularly a kind of deck structrue of being combined by prefabricated ultra-high performance concrete plate and steel bridge deck and construction method.
Background technology
The bridge deck structure of highway steel bridge, primarily of bridge deck and deck paving composition, is the primary structure directly bearing wheel load on bridge and it is delivered on girder, is also one of position of most rapid wear in bridge construction.Be mainly manifested in steel bridge deck cracking and the fragile disease of deck paving.Although domestic and abroad bridge circle and road circle personage have done a large amount of theories and experimental study to steel bridge deck and paving steel bridge deck, attempt the material property improving compound of mating formation, optimized pave-load layer thickness, improved Steel Bridge Deck structure, improved the methods such as welding procedure technique.But from general principle, because steel bridge deck stiffness by itself is low, and flexible pave-load layer modulus low (particularly summer), the stress that effectively can not improve bridge deck rigidity and reduce in each layer, its distortion again more difficult steel bridge deck larger with distortion is coordinated, and does not therefore fundamentally solve the appearance of bridge deck structure disease.
In the prior art, by the inspiration of highrise building Composite Slab with Metal Deck research and apply, some scholars attempt and compoboard are applied to bridge deck to improve bridge floor rigidity, avoid the generation of Steel Bridge Deck system disease.Because bridge has the features such as span is large, load is large, some scholars again trial light weight concrete construction, steel fibrous concrete, high performance concrete replace ordinary concrete.But under Vehicle Load, be positioned at stiffening rib, the bridge deck at diaphragm and midfeather place can form hogging moment area due to supporting role, tensile strength by material self limits, and structure stress still can not meet the demands, in engineering practice, still occur deck paving cracking phenomena.On the other hand, under bridge deck structure is directly exposed to environment, bear the external loads such as driving, People's Bank of China, wind-force and temperature, and the effect of the environmental factor such as humidity, air institute chloride ion-containing.Therefore, bridge deck structure, except possessing enough intensity, rigidity and good overall performance, also should have enough cracking resistances, shock resistance, the performance such as wear-resisting.
In the prior art, have a kind of steel and ultra-high performance concrete combined bridge deck structure, its shearing resistance structure adopts peg and PBL connector, as shown in Figure 1 (to weld the example of nail as conventional shear connector 5).Ultra-high performance concrete (UHPC) is the very-high performance Fiber Reinforced Cement Based Composites of a kind of high strength, high-modulus, high ductility, and by the steel fibre that mixes certain volume content in UHPC layer with arrange that steel mesh reinforcement strengthens the resistance to tension of structure further.UHPC has high compactness, high impervious coefficient simultaneously, makes steel bridge deck be in good corrosion-resistant state.This kind of combined bridge deck structure adopts integral cast-in-situ construction, due to the easy shrinkage cracking of ultra-high performance concrete, existing cast-in-place construction technology cannot ensure construction quality, and the maintenance difficulty of large-area cast-in-situ concrete is very large, concrete strength can be subject to very large reduction because maintenance is not in place, this will greatly reduce the life-span of bridge deck pavement.If take working measure to overcome the unfavorable factor of integral cast-in-situ construction generation, operating expenses will be caused significantly to increase.
