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.
Summary of the invention
The object of this invention is to provide a kind of simple and reasonable, stress performance and excellent in durability, easy construction and the bridge deck pavement structure that can effectively prevent bridge floor from ftractureing and paving method.
For achieving the above object, technical scheme of the present invention 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.
The paving method of bridge deck pavement structure, comprises the steps: a, by integrally welded to top board, longitudinal web and diaphragm, forms girder steel; B, by rigid posts according to rectangle or be quincunxly uniformly welded on top board, wrap up flexible cladding from rigid posts root to 1/3 ~ 3/4 At The Height; C, at top board end face upper steel fibrous concrete, form steel fibrous concrete layer, and ensure that rigid posts end face is lower than steel fibrous concrete layer surface; D, at steel fibrous concrete layer upper asphalt concrete, form asphalt concrete layer, thus final form whole bridge deck pavement.
Welding manner in described step b is downhand welding.
Rigid posts in described step b is connected with application and finer wire, iron wire improving bud grafting with between flexible cladding.
Compared with prior art, advantage of the present invention is:
1, bridge deck pavement structure of the present invention, it is simple and reasonable, flexible connecting member has that shearing rigidity is low, anti-fatigue performance 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.
4, paving method of the present invention, easy and simple to handle, the pave-load layer shape that steel fibrous concrete layer and asphalt concrete layer are laid is in aggregates, and resistance to tension increases, thickness increases, effectively can reduce tensile stress and the stretching strain on pave-load layer surface, thus the problem of Cracking on pave-load layer surface can effectively be solved, flexible connecting member makes the relative deformation ability between steel fibrous concrete and top board strengthen simultaneously, local crushes phenomenon can effectively to avoid the concrete of flexible connecting member near zone to occur, and bear shearing by the bar portion of flexible connecting member is bending, effectively improve anti-fatigue performance, also the corrosion of top board can be avoided in addition well.
