Description
Technical field
The present invention relates to a kind of compound section steel box girders and its method of construction for high-speed railway, belong to high-speed railway bridge neck
Domain.
Background technique
Currently, simply supported girder bridge mostly uses T section beam or box-girder in high-speed railway field, the former is referred to as T
Beam, the latter are referred to as box beam.Because the T beam bridge lateral stiffness of T beam composition is smaller, anti-twisting property is poor, and stability when installation
Poor, the field operation time is long, uses when being not suitable for compared with large span.Simply supported girder bridge compared with large span generally uses box beam.
Box beam includes concrete box girder, steel box-girder and compound section steel box girder.When span is larger, the weight of concrete box girder is very
Greatly, difficulty is brought to pouring or set up, such as 32 meters of high-speed railway integrated box girder weighs about 900 tons, builds height in land
Fast railroad bridge should not use the concrete box girder of more large span.The rigidity of steel box-girder is relatively low, is not suitable for flatness
It is required that extremely stringent high-speed railway field.Therefore, the simply supported girder bridge of more large span is considered as using combination steel in high-speed railway
Box beam.
Compound section steel box girder is composed of the steel case and the concrete slab on top flange plate of lower part, passes through shear connections
Part is connected.The feature that concrete anti-compression ability is strong and steel tensile capacity is high is utilized, takes full advantage of material property.Steel case
The anti-twisting property of beam is strong, and erection construction is easy, and is suitably applied highway and Urban Bridge.It is applied to high-speed railway bridge then still
There is disadvantage, is exactly that vertical rigidity still is apparent not enough.Main cause is that bottom parts only have steel plate, and thickness is typically small.Increase group
The thickness for closing steel box-girder steel plate of baseplate is a kind of strategy, but the more economical thick steel plate thickness that steel and iron industry provides is not too large,
And thicker steel plate brings difficulty to construction and subsequent manufacture.Welding steps up rib on bottom plate, and rib spacing of putting more energy into is made by welding
The limitation of industry, and a large amount of welding increases manufacturing expense.Therefore welding ribbed stiffener is limited to stiffness is improved, should be by coagulation
Soil material increases contribution of the box beam bottom plate to rigidity.
A kind of scheme is the direct casting concrete on the steel sole plate of compound section steel box girder, but the tensile capacity of concrete material
Lower, under working load effect, concrete will crack after tension.If applying prestressing force to it, then after casting concrete
Because of the presence of steel sole plate, the prestressing force applied just only has partial action on concrete slab, and with concrete shrinkage, Xu
The progress of change, the prestressing force in concrete will be gradually reduced, and be a kind of inefficient method, and still may working load make
Cracking under.Another scheme is to use bottom plate of the steel case as steel box-girder, internally concrete perfusion or mortar, and then
Apply prestressing force, this is a kind of good method, can satisfy engineer application, but still having the disadvantage in that prestressing force still has greatly
Partially " consume " on steel case, and the tensile capacity of steel case is strong, does not need the partial prestressing；Concrete in steel case
Or mortar there are still shrink, problem of creeping, internal prestressing force can reduce in use；If being poured before erection in steel case
Concrete or mortar just will increase lifting weight；If it is installed in place concrete or mortar in after-pouring bottom plate in steel case, then
With post-stress, then construction speed is influenced；Because of template of the bottom plate as casting concrete or mortar of steel case, it is determined
Width can not be larger, and a combination beam is not able to satisfy the needs of whole picture bridge, can only be using laterally assembled with more beams
Form can thus make field operation complicated and increase the activity duration.Therefore, be badly in need of in high-speed railway bridge it is a kind of efficiently and can
The compound section steel box girder of rapid construction.
Summary of the invention
It is an object of the invention to solve the problems, such as above-mentioned the deficiencies in the prior art and, provide a kind of for high speed
The compound section steel box girder and its method of construction of railway.The compound section steel box girder surface with general compound section steel box girder, including steel case,

And the vertical, horizontal ribbed stiffener of bottom wing listrium.
Further, the prestressed concrete plate in steel case is made using super high strength concrete.This mainly considers
Concrete to tensile region can generate biggish stretching strain under working load effect, should have in prestressed concrete plate sufficiently large
Prestressing force deposit.In recent years, the development of super high strength concrete provides support thus, and prefabricated superelevation is mixed by force under general condition
Solidifying soil intensity is close to 200MPa, and uses the concrete of reactive powder production, and after steam curing appropriate, intensity is more than
300MPa, close to the intensity of conventional steels.Meanwhile the tensile strength of super high strength concrete is also accordingly improved.In this way, prefabricated
Prestressed concrete plate in can store more than the compressive pre-stress of 50MPa, consider further that the tensile strength itself having, answer in advance
