Description
Technical field
The utility model belongs to bridge construction field of engineering technology, particularly a kind of bridge deck pavement structure.
Background technology
At present, in Longspan Bridge, orthotropic steel bridge deck is light with its component quality, transport is widely used gradually with features such as setting up convenience, short construction period, existing most of Steel Bridge plate all adopts orthotropic steel bridge deck, namely longitudinal web (vertical rib) is welded in the top board bottom surface of Steel Bridge plate, in longitudinal web, be provided with the diaphragm (cross rib) orthogonal with it, thus form orthotropic structural slab.
Bridge deck pavement is generally made up of the thin layer steel concrete be laid on top board and bituminous concrete, lays steel mesh reinforcement in steel concrete.In whole Orthotropic steel bridge deck structure, orthotropic structural slab is equivalent to sinking support, and under Vehicle Load, the tensile stress of bridge deck pavement localized positions reaches 3MPa ~ 7MPa, and ordinary reinforced concrete is difficult to meet the demands.
Because above-mentioned orthotropic steel bridge deck needs to arrange plain bars net, manufacture craft more complicated, there are stress raisers, this make also causes many mat formation disease and problem simultaneously, major embodiment is: 1, the load such as automobile is overweight can correspondence cause bridge deck pavement surface stretching strain excessive, easily causes bridge deck pavement vertical and horizontal to ftracture; 2, bridge deck pavement durability is not enough, under the course under cyclic loading of automobile, and the easy creep of compound of bridge deck pavement, thus form permanent deformation, permanent accumulation then develops into rut; 3, the connector rigidity between bridge deck pavement and top board is comparatively large, easily causes the concrete near connector to crush in stressed early stage appearance and destroys; 4, the combination between bridge deck pavement with top board does not conform to current common design assumption, and the analogy method between both interfaces exists dispute.
Utility model content
The bridge deck pavement structure that the purpose of this utility model is to provide a kind of simple and reasonable, stress performance and excellent in durability, easy construction and can effectively prevents bridge floor from ftractureing.
For achieving the above object, the technical solution of the utility model is: a kind of bridge deck pavement structure, the orthogonal longitudinal web that is connected comprising that top board and top board bottom surface be connected and diaphragm, top board end face upper berth is provided with bridge deck pavement, and described top board end face is provided with the flexible connecting member being positioned at bridge deck pavement.
Described flexible connecting member comprises the flexible cladding of rigid posts and the outside from rigid posts root to 1/3 ~ 3/4 At The Height, and rigid posts is connected with top board is vertical, and rigid posts end face is lower than bridge deck pavement surface.
Described bridge deck pavement comprises the steel fibrous concrete layer and asphalt concrete layer laid successively from below to up, and flexible connecting member end face is lower than steel fibrous concrete layer surface.
Steel fibre volume ratio in described steel fibrous concrete layer is 6% ~ 10%.
Described rigid posts is weldering nail, reinforcing bar or angle steel, and described flexible cladding is polyurethane resin sponges cover, foamed plastics cover or rubber sleeve.
Described flexible connecting member is rectangular or to be quincunxly uniformly welded on top board.
Compared with prior art, advantage of the present utility model is:
1, orthogonal longitudinal web of being connected that the utility model comprises that top board and top board bottom surface be connected and diaphragm, top board end face upper berth is provided with bridge deck pavement, described top board end face is provided with the flexible connecting member being positioned at bridge deck pavement, it is simple and reasonable, it is low that flexible connecting member has shearing rigidity, anti-fatigue performance is good, breakout capacity and the constant feature of shear strength, initial stage shear stiffness is little, shearing maintains about 1/3 of intensity and continues sliding deformation, effectively can reduce the shear value of local connector, the bridge deck pavement improved near rigid posts is stressed, effectively avoid bridge deck pavement to crush to destroy, thus improve the Local Cracking phenomenon on pave-load layer surface, and meet current common design assumption, rely on flexible connecting member bar portion to bend and bear shearing, anti-fatigue performance is good, stress performance and excellent in durability, builds easy construction, effectively can solve many mat formation disease and problem that current Steel Bridge Deck Pavement exists.
2, bridge deck pavement comprises the steel fibrous concrete layer and asphalt concrete layer laid successively from below to up, and deck paving layer thickness increases, and can improve the bad phenomenon such as distortion, Vehicular vibration because local wheel load produces, thus effectively improve the comfort level of driving; Adopt steel fiber reinforced concrete structure, the tensile property of bridge deck pavement can be strengthened, and effectively prevent the cracking phenomena of bridge deck pavement; In addition, without the need to arranging steel mesh reinforcement, simplify working procedure, easy and simple to handle.
3, flexible connecting member can reach that shearing rigidity is low, anti-fatigue performance good, breakout capacity and the constant effect of shear strength; Flexible connecting member is rectangular or be quincunxly uniformly welded on top board, and uniform force, welding manner is convenient to mechanized construction and the control to workmanship, effectively can ensure construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Bridge deck pavement structure as shown in Figure 1, it comprises longitudinal web 2 and diaphragm 1 that top board 3 and top board 3 bottom surface are connected, and longitudinal web 2 is orthogonal with diaphragm 1 to be connected.
Top board 3 end face is provided with flexible connecting member 4, flexible connecting member 4 is rectangular or be quincunxly uniformly welded on top board 3, flexible connecting member 4 comprises rigid posts 5 and the flexible cladding 6 from rigid posts 5 root to 1/3 ~ 3/4 At The Height parcel, rigid posts 5 and top board 3 vertical welding.
