Description
Technical field
The invention belongs to steel structure bridge technical fields, are related to a kind of Orthotropic Steel Bridge Deck knot with lateral binder
Structure.
Background technology
Orthotropic Steel Bridge Deck be the design of current steel structure bridge and build in through frequently with one kind for directly holding
The structural unit of bridge floor vehicular load is carried on a shoulder pole, it has many advantages, such as from heavy and light, high capacity, easy for construction.Orthotropic steel bridge deck
Plate is mainly made of the longitudinal stiffener and transverse stiffener (or diaphragm plate, crossbeam) that are welded on cover board and its lower surface, by
It is different in the vertical cross stiffness of this steel bridge deck, therefore this steel bridge deck is claimed to be referred to as Orthotropic Steel Bridge Deck.Wherein,
Longitudinal stiffener includes Research on Open Stiffener (such as rib of slab, flat-bulb steel rib, L-shaped rib, T shapes rib) and silent ribbed stiffener (such as trapezoidal rib, U
Shape rib, V-arrangement rib, Y shape rib), since silent ribbed stiffener has many advantages, such as that torsional rigidity is big, it is usually used in garage's Steel Bridge knot
In structure.
Use the structure of the Orthotropic Steel Bridge Deck of silent ribbed stiffener for：Longitudinal silent ribbed stiffener and transverse stiffener phase
Mutual square crossing is welded on cover board lower surface.In use, due to the repeated action of vehicular load so that the structure is being answered
Power concentrates most sensitive position easily to generate fatigue crack, especially welds near sites, silent in silent ribbed stiffener field joint
Ribbed stiffener and cover board welding position nearby, silent ribbed stiffener and cross rib (or diaphragm plate, crossbeam) handing-over position, weld easily occurs
Cracking, reduces the service life of bridge, and there are serious security risks.In addition, for the ease of longitudinal silent ribbed stiffener with
The welding of cover board needs to open up through hole on transverse stiffener, to step down to longitudinal silent ribbed stiffener, but passes through simultaneously
The weakening of perforation opened up and can cause transverse stiffener partial cross section reduces the intensity of transverse stiffener, and then influences orthogonal
The holistic resistant behavior of anisotropic steel bridge deck.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can improve it is anti-tired
Labor cracking performance and the good Orthotropic Steel Bridge Deck structure with lateral binder of stress performance.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of Orthotropic Steel Bridge Deck structure with lateral binder, the structure include cover board, multiple are disposed in parallel in
Longitudinal stiffener on cover board lower surface and it is multiple be disposed in parallel on longitudinal stiffener lower surface and with longitudinal stiffener phase
Vertical lateral binder, the longitudinal stiffener are Research on Open Stiffener, which includes being arranged in cover board lower surface
The upper and longitudinal stiffener vertical portion vertical with cover board and setting are in longitudinal stiffener vertical portion bottom and and longitudinal stiffener
The vertical longitudinal stiffener horizontal part in vertical portion, passes through welding by both sides between the top and cover board of the longitudinal stiffener vertical portion
Seam is fixedly connected, and multiple longitudinal stiffeners are fixed together by the lateral binder by longitudinal stiffener horizontal part.
Convenient for being fixedly connected using double welded joint between cover board, longitudinal stiffener horizontal part is convenient for and transverse direction for longitudinal stiffener vertical portion
Binder is fixedly connected.
The Research on Open Stiffener includes one kind in L fonts ribbed stiffener or inverted T font ribbed stiffener.
It is bolted to connection between the top and longitudinal stiffener horizontal part of the lateral binder.Lateral binder with
It is connected by screw bolts mode between longitudinal stiffener horizontal part, the speed of structure assembling can either be improved, shortens construction period, and
Connectivity robustness is good, while bolt has certain torsion resistant and bending resistant ability, can improve the stress performance of structure entirety.
The top of the lateral binder is equipped with lateral binder horizontal part, and is put more energy into longitudinal by lateral binder horizontal part
Rib horizontal part is fixedly connected.Lateral binder horizontal part fits with longitudinal stiffener horizontal part, is realized later by bolt quick
Connection.
The lateral binder includes one kind in angle steel, I-steel, H profile steel or T-steel.Steel also can be selected in lateral binder
Steel flanged beam crossbeam, truss-like crossbeam or the diaphragm plate of bridge girder.
The double welded joint includes one in full penetration double welded joint, partial penetration double welded joint or twin fillet wolt
Kind.
According to actual conditions, the both ends of lateral binder can be connect with the web of girder or longeron.
In the steel bridge main beam design stage, should be determined according to engineering functional requirement and structural stress analysis：(1) cover board steel plate
Thickness；(2) pattern (L fonts ribbed stiffener or inverted T font ribbed stiffener), specification (the longitudinal stiffener cross section ruler of longitudinal stiffener
Very little, plate thickness), spacing (be located at cover board on lateral distance)；(3) pattern (angle steel, I-steel, H profile steel or the T-type of lateral binder
Steel), specification, spacing, the steel flanged beam crossbeam, truss-like crossbeam or diaphragm plate for steel bridge girder can also be expanded；(4) longitudinal to put more energy into
Rib and cover board welded seam pattern；(5) type of attachment of lateral binder and longitudinal stiffener, preferred bolt connection.
The stage is fabricated in steel bridge girder, welds longitudinal stiffener on the cover board first, form of implementation should be according to steel bridge
Functional requirement, structural stress analysis and the manufacturing process of panel determine, then install lateral binder.Floorings of the present invention can
Other girder components assemble to form steel girder with web or longeron, crossbeam etc., and the cover board of floorings is using molten between steel girder segment
Weldering docking, the docking of longitudinal opening ribbed stiffener are connected by screw bolts thoroughly.
Compared with prior art, the invention has the characteristics that：
1) by selecting Research on Open Stiffener to be used as longitudinal stiffener, making can be by two-sided between longitudinal stiffener and cover board
Weld seam is fixed and welded together, and reduces stress concentration, effectively increases the antifatigue cracking performance of structure, extend making for structure
With the service life, safety is good；
2) it since the torsional rigidity of Research on Open Stiffener is weaker than silent ribbed stiffener, is set on the lower surface of Research on Open Stiffener
Lateral binder is set, and is fixed together the longitudinal opening ribbed stiffener for being mutually juxtaposed setting by lateral binder, becomes one
A entirety to improve the torsional rigidity and uniform force of structure, and then is improved together with cover board shared bridge floor vehicular load
The holistic resistant behavior of structure；
3) lateral binder is arranged on the lower surface of longitudinal stiffener, lateral binder is avoided mutually to be handed over longitudinal stiffener
It pitches and needs the case where opening up through hole on lateral binder, because of the weakening without leading to lateral binder partial cross section, effectively
It ensure that the intensity of lateral binder.
