Description
Technical field
The utility model relates to bridge engineering, especially relates to a kind of combined bridge deck be applied in Large Span Bridges and Urban Bridge.
Background technology
Orthotropic Steel Bridge Deck has that quality is light, transport with set up the advantages such as convenience, short construction period, supporting capacity are large, have a wide range of applications in Large Span Bridges and Urban Bridge, but Orthotropic Steel Bridge Deck steel using amount is large, cost is higher, under Concentrated load, local distortion amount is comparatively large, can produce secondary stress in weld seam constraint place; Within the bridge design life-span, be subject to repeatedly rolling of wheel and easily produce fatigue crack.Due to the complex structure of clean steel bridge floor, weld seam quantity is many, and welding difficulty is large, so factory's manufacture, Assembling precision and welding quality require all very high.In addition the natural environment residing for deck paving and load environment are comparatively severe, be subject to the multiple actions such as heavy duty, high temperature, vibration, cause the corrosion of clean steel bridge deck structure, weld seam produces fatigue crack, the diseases such as pave-load layer generally ftractures, need time serious to remove and bridge deck of again constructing.
The superposed beam that girder steel and concrete slab form avoids clean steel bridge deck Problems existing to a certain extent, but the girder steel of superposed beam mostly adopts opening section form, needs to rely on lateral ties composition overall between girder steel; Girder steel and concrete slab are out of shape asynchronous under TEMPERATURE FORCE and convergent force effect; Girder steel top needs to contact completely with concrete slab, and there is the problem that anti-torsion poor-performing, concrete slab weight are comparatively large, Site Welding amount is large, thus its range of application is restricted.
Summary of the invention
The purpose of this utility model is that providing a kind of combines the combined bridge deck being applied to Large Span Bridges and Urban Bridge with concrete slab by corrugated sheet steel.
For achieving the above object, the utility model can take following technical proposals:
The combined bridge deck be applied in Large Span Bridges and Urban Bridge described in the utility model, comprises bridge floor plate body, and described bridge floor plate body is combined by the corrugated sheet steel of bottom and the concrete slab on top; The shear connector be symmetrically welded on described corrugated sheet steel crest extends upwardly in described concrete slab; Be provided with stiffener in the equilibrium of the middle part of described concrete slab and tie up the ring-shaped stirrup of described stiffener.
Described shear connector is peg, shaped steel or perforated panel.
The thickness of described corrugated sheet steel is 6 ~ 30mm, and the spacing between adjacent two crests/trough is 0.4 ~ 1.0m.
The thickness of described concrete slab is 50 ~ 160mm.
Described stiffener is along bridge to elongated layout, and its diameter is 10 ~ 28mm; The ring-shaped stirrup diameter arranged perpendicular to described stiffener is 10 ~ 20mm, and the spacing between adjacent two ring-shaped stirrups is 100 ~ 300mm.
Described ring-shaped stirrup and described shear connector are interconnected.
The utility model has the advantage of and be mainly reflected in the following aspects:
1) strong for corrugated sheet steel shear resistance, that tensile strength is high feature and the high feature of concrete slab compressive strength are combined, make full use of the performance of material, under heavy load, there are enough bending bearing capacity, do not lose prior to the supporting capacity of integral bridge and destroy; Under Concentrated load, there is enough little distortion, steel work can be avoided to occur fatigue problem.
2) adopt concrete slab to replace the top board of conventional steel bridge deck, the cost of bridge deck can be reduced.
3) corrugated sheet steel can be stamped to form by general steel plate, is easy to large-scale standardized production, is convenient to sections transport;
4), after adopting corrugated sheet steel, welding capacity is very little, can reduce the multiple bridge deck disease because welding procedure self-defect causes;
5) under transverse temperature effect and concrete shrinkage effect, the fold effect of corrugated sheet steel significantly can reduce steel plate and the nonsynchronous problem of concrete deformation, can reduce the stress of bridge deck direction across bridge, avoid the cracking of bridge deck direction across bridge;
6) on concrete slab, only adopt conventional asphalt concrete pavement just can meet the needs of driving, and be easy to change, the ubiquitous fragile problem of mating formation of conventional orthogonal opposite sex steel bridge deck can be avoided;
7) the Orthotropic Steel Bridge Deck structural form with conventional is close, easily directly applies to the replacing of newly-built steel bridge construction or built Steel Bridge Deck system.
Accompanying drawing explanation
Fig. 1 is section structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the combined bridge deck be applied in Large Span Bridges and Urban Bridge described in the utility model, comprises by the corrugated sheet steel 1(base plate of bottom) and the concrete slab 2(top board on top) the bridge floor plate body that combines: the shear connector 3 be symmetrically welded on corrugated sheet steel 1 crest extends upwardly in concrete slab 2; Along bridge, elongated equilibrium is provided with stiffener 4 at the middle part of concrete slab 2, and forms entirety after being connected by the ring-shaped stirrup 5 tying up stiffener; Ring-shaped stirrup 5 and shear connector 3 are interconnected, and guarantee there are enough shear stiffnesses between corrugated sheet steel 1 and concrete slab 2.
In actual use, shear connector 3 can be peg, shaped steel or perforated panel structure; Force analysis according to cross-section structure and bridge deck is determined, the thickness of corrugated sheet steel 1 is 6 ~ 30mm, and the spacing between adjacent two crests/trough is 0.4 ~ 1.0m.Select according to the needs of form of structure and bridge deck force analysis is determined, the thickness of concrete slab 2 is 50 ~ 160mm; Suitable bridge is 10 ~ 28mm to the diameter of the stiffener 4 of elongated layout; Ring-shaped stirrup 5 diameter arranged perpendicular to stiffener 4 is 10 ~ 20mm, and the spacing between adjacent two ring-shaped stirrups is 100 ~ 300mm.
During construction, the steel plate punched that corrugated sheet steel 1(selects thickness suitable is formed) tile on the ground, its crest face is carried out the welding of shear connector 3; Then in the trough of corrugated sheet steel 1, steel form or the air bag consistent with trough shape is filled as inner membrance, be divided into two-layer up and down at the top colligation stiffener 4 of corrugated sheet steel and ring-shaped stirrup 5(stiffener 4, be connected with the levels of ring-shaped stirrup 5 respectively, the lower floor of ring-shaped stirrup 5 is connected with shear connector 3 simultaneously, make it formation entirety), form concrete slab 2 finally by fluid concrete, corrugated sheet steel 1 forms combined bridge deck system as the concrete slab 2 at base plate and top.
At present conventional steel bridge deck form of mating formation comprises pouring asphalt concrete and mats formation, bitumastic concrete pavement, epoxy resin asphalt concrete pavement three kinds, mating formation of these three kinds of forms all has very strict temperature and humidity requirement at work progress, need to adopt special construction technology and construction equipment, and in the application, the construction of each component all adopts conventional construction method and construction equipment to realize.The contrast of each bridge deck performance is as shown in the table
