Description
Technical field
The utility model belongs to hollow slab beam reinforcing technique field, especially relates to a kind of steel plate and concrete composite reinforcing construction of hollow slab beam.
Background technology
China's speedway Large scale construction starts from the mid-90 in last century, current many local roads bridge has been runed nearly 30 years, even reaches 40-50, has reached or has approached design reference period, or exist a variety of causes to cause Structural defect and damage, all need to carry out maintenance and reinforcement.According to Second National Highway General Survey statistics, in domestic 27.8 ten thousand highway bridges, three, the four classes bridge of reinforcing that needs repairing accounts for 10% left and right, and in current all kinds bridge, assembling hollow slab bridge is bridge type conventional in Bridges in Our Country engineering.It is simple that assembling hollow slab bridge has form of structure, little, the prefabricated convenience of building height, by material economy, be easy to the feature such as batch production and standardized construction, and veneer transportation and hoisting process in good stability.In assembling hollow slab bridge each plate-girder laterally between by cast-in-place tongue and groove concrete pin, and multi-disc beam is formed to entirety, Local Loads transverse distribution on carriageway plate is born jointly to each plate-girder, reduce so significantly even to avoid single plate-girder stressed, reach cooperative bearing object.Short/Medium Span Bridge below current domestic highway bridge 20m all adopts hollowcore slab structure substantially.
From the operation situation of built bridge, there are some comparatively typical diseases in hollowcore slab structure.Investigation and analysis shows, affects that hollow slab bridge is normal to be used and the distinct issues of structural safety are that lateral ties structure is on the weak side, and veneer rigidity is lower, and tracing sth. to its source is the destruction that hinge is stitched.After hinge seam or transverse splicing destruction, vehicular load is transverse distribution effectively, formation veneer is stressed, the very large and wide range of its harmfulness, except causing that plate-girder itself destroys, also can cause the destructions such as deck paving, stretching device, bridge pad, abutment pier, bridge floor planeness is reduced, even bridge deck pavement occurs ftracture, having gathered around, fragmentation, the phenomenon such as peels off.The comfortableness that this has not only seriously affected driving, has increased the potential safety hazard of driving a vehicle, and also greatly reduces the integrated carrying ability of bridge construction.Overweight vehicle is more now simultaneously, proof load while acting on the loading ratio design on independent hollowcore slab increases exponentially, and plate-girder is under the effect of these loads, and its amount of deflection increases greatly, under the repeated action of vehicular load, easily form plate-girder cracking, the plate that can break when serious caves in.
At present, the conventional reinforcement means of hollowcore slab structure has the reinforcing of bridge floor strengthening course, laterally affixing steel plate reinforcement, transverse prestress reinforcing, beam-removing rib-increasing strengthening, chemical grouting reinforcing etc.Wherein, when the construction of bridge floor strengthening course reinforcing method, need cut original deck paving, and connecting reinforcement and steel mesh reinforcement are set, after reinforcing, deadweight increases, supporting capacity improves not remarkable, use of occasion that can be less in resistance to compression cross section, and not remarkable to improving hollow slab bridge transverse integral.Laterally affixing steel plate reinforcement method is, by adhesive and crab-bolt, vertical steel plate direction across bridge stickup is anchored to hollowcore slab hinge seam place, bear the effect of lateral ties by more soft steel plate, under course under cyclic loading, easily cause steel plate and concrete to depart from, in addition after the breakage of hinge seam by the rain erosion causing, consolidation effect fails gradually, and the stressed stress hysteresis that exists of steel plate.Beam-removing rib-increasing strengthening method is to remove the more serious girder of indivedual damages, the maintenance of residue girder is also spaced within the scope of former bridge width again, recycle the newly-increased prestressed concrete beam rib in space between old beam slab, when construction, to lift by crane beam slab, engineering quantity is large, and increase material usage, comparatively applicable in the situation that of only serious in crack.Chemical grouting hinge seam reinforcing method is that chemical grouting material is pressed into hinge seam closed cavity, after cementitious materials setting and harden, form entirety with concrete, reach the object that shutoff is reinforced, although this method technique is simple, but most of chemical grouting materials are expensive, polymer chemistry slurry material has toxicity in various degree, and the aging and durability of polymer also lacks long-term observational data, general alternative of only stitching maintenance and reinforcement as hinge.In addition, abroad also have and adopt transverse stretching prestressed reinforcement to strengthen the scheme that transverse integral connects, construct more difficult in practice, cost is higher, and appearance effect is poor.To sum up, above-mentioned several reinforcement means have drawback separately, also have applicable elements separately.Thereby, nowadays lack the steel plate and concrete composite reinforcing construction of a kind of simple in structure, reasonable in design while easy construction, hollow slab beam that consolidation effect is good, it can effectively solve the problems such as construction inconvenience, input cost that existing hollow slab beam reinforcement means exists are higher, consolidation effect is poor.
