Technical field
The present invention relates to technical field of bridge engineering, and in particular to a kind of truss-like steel box-girder diaphragm plate.
Background technology
Steel box-girder is usually the envelope being formed by connecting by top plate, bottom plate, web, diaphragm plate and ribbed stiffener etc. by welding manner
Close box structure.Because box structure has good bending resistance, antitorque and lateral stability, therefore steel box-girder is Large Span Bridges
Conventional structure type.Minor radius, special-shaped beam, across crossing, building height is limited, has rapid construction and Bridge Landscape demand
Short/Medium Span Bridge engineering in, the application of steel box-girder is also increasingly extensive.
The thickness of steel box-girder roof and floor and web is very small compared with bridge depth of beam and width, be typically remain silent it is thin
Wall construction.To prevent steel box-girder section from transverse curvature, torsion and distortion deformation occurs, the shape of box section is kept, it is necessary to set
Put enough diaphragm plates.
Conventional steel box-girder diaphragm plate uses steel flanged beam diaphragm structure, as shown in figure 1, diaphragm plate is one block of steel plate, root
A certain degree of needs for hollowing out, constructing and conserving with satisfaction can be carried out according to demand.Because steel plate Out-of Plane Stiffness is relatively low, to ensure
Diaphragm plate has enough rigidity, it is necessary to set vertical and lateral stiffening on diaphragm plate.
Conventional diaphragm plate causes welding job amount big, construction is complex due to the steel flanged beam steel plate put more energy into using band.
The current and pipe of personnel supports passing through for equipment during steel flanged beam steel diaphragm plate is also unfavorable for constructing and runing simultaneously.In addition, real abdomen
Formula diaphragm plate steel using amount index is high, and Technical Economy is poor.Therefore, it is necessary to according to the construction features of steel box-girder, bridge is being ensured
On the premise of beam strength, rigidity and stability, simple structure, index economization, construction and the operation maintenance of diaphragm plate are realized
Facilitation.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of truss-like steel box-girder diaphragm plate, it is ensuring steel box-girder diaphragm plate
On the premise of anti-torsion and distortion ability, steel using amount is reduced, improves the space of steel box-girder internal structure so that steel box-girder exists
It is more convenient in terms of construction and operation maintenance.
The realization of the present invention is completed by following technical scheme：A kind of truss-like steel box-girder diaphragm plate, including it is arranged at steel case
Diaphragm plate in beam, it is characterised in that the diaphragm plate uses truss structure, described truss structure and described steel case
Beam inwall is welded to connect, and forms truss-like steel box girder.
Further, described steel box-girder is made up of top plate, bottom plate, web and its corresponding put more energy into, described steel box-girder
Top plate, bottom plate and web form enclosed construction by being welded to connect.
Further, described diaphragm plate put more energy into by pricncipal rafter, truss lower boom, web vertical, the gusset plate that winds up,
Lower-chord panel point plate and truss web composition, truss web by the gusset plate that winds up, lower-chord panel point plate respectively with pricncipal rafter, purlin
Frame lower boom is welded to connect, and forms truss structure.
Further, the T-bar that described pricncipal rafter is made up of pricncipal rafter web and pricncipal rafter wing plate
Part forms.
Further, the T-bar that described truss lower boom is made up of truss bottom chord web and truss lower boom wing plate
Part forms.
Further, described truss web is made up of shaped steel such as circular cross-section steel pipe or channel-section steels.
The present invention is a kind of truss-like steel box-girder diaphragm plate, and steel box-girder uses full steel structure, no precast slab.Truss
The top with steel box-girder, bottom plate weld to form entirety the upper and lower chord member of formula diaphragm plate respectively, truss-like diaphragm plate of the present invention it is upper,
Lower boom is welded using steel plate, belongs to pass force crossly component, to preventing the transverse direction of steel box-girder from construction stage to operation stage
Bending, torsion and distortion deformation have the function that important.It is an advantage of the invention that：1. reduce the steel using amount of steel box-girder；2. truss
Web member uses shaped steel, easy for construction；3. increase steel box-girder inner space；4. it is easy to the arrangement of box beam gut line；It is easy to the later stage
Maintenance.
