Description
Technical field
It is especially a kind of for bridge, the steel braced girder composite structure of vestibule, green road the present invention relates to a kind of bridge field.
Background technology
Immediate with the present invention should be traditional steel truss girder bridge and aluminium alloy truss bridge, both by truss member group
At every truss member is primarily subjected to axial force, is to replace whole chamber with sparse web member compared with box-girder, to save
Material saving mitigates dead load and increases span ability.But the rod piece of traditional steel truss girder is in order to ensure the equilibrium of its stress
And stability, often size is larger, and truss is higher, and there are certain requirements to headroom, causes its moulding heavy ugly, and steel are used
Amount is also maintained at a higher level；Although the dead weight of aluminium alloy truss bridge, compared with light, durability is preferable, cost is high, purlin
Frame is equally higher, landscape effect is single.
Invention content
To solve the above problems, the present invention proposes a kind of under the premise of ensureing overall stability and safety, effective drop
Low beam body, the structure height of truss reduce whole steel using amount, can form beautiful three-dimensional contouring, and convenient for batch production, standard
Change the steel braced girder composite structure of processing, manufacture, transport, installation.
The steel braced girder composite structure that the present invention designs, including steel construction girder, the steel construction girder include lateral structure
Part is equipped with top bearing plate on cross member top, the side case for participating in longitudinal stress is symmetrically arranged in the both sides of cross member
Room, the side chamber top are equipped with the truss-like railing for participating in stress, the truss-like railing include handrail steel member with
Lattice format truss member, lattice format truss member form Fence structure, and lattice format purlin between handrail steel member and side chamber
Hack lever part upper end is fixedly connected with handrail steel member, and lattice format truss member lower end is fixedly connected with side chamber.This structure
Feature is that handrail steel member and side chamber are linked together using lattice format truss member, to which handrail steel member to be added to
In force structure.
Further embodiment is that the lattice format truss member is two-row structure, and two rows of lattice format truss members prolong side
Chamber direction extends, and forms three-dimensional contouring.Or lattice format truss member is single row configuration, and lattice format truss member prolongs side chamber
Direction extends, and forms three-dimensional contouring.
Further embodiment is that necessity that in the chamber of the side and lower part of top bearing plate is equipped with increase local stiffness is put more energy into
The bottom of rib, cross member is equipped with bottom sealing plate.
Further scheme is that the handrail steel member is led to by steel side or rectangular steel pipe forms.
Compared with prior art, steel braced girder composite structure obtained by the present invention includes the overall steel of steel construction girder composition
The both sides truss structure that box beam and truss-like railing are constituted, the two is according to rigidity than carrying out load action distribution.Overall steel box beam
On the one hand stress is participated in as girder construction and bridge deck structure, the side chamber being on the one hand arranged by both sides is joined as lower boom
With the stress of truss-like railing.Only it is transformed into lattice format truss member as the railing of accessory structure by conventional, with integral steel box
The side chamber of beam, which links together, participates in structure stress.
Steel construction girder lower part uses box-shaped steel structure, as possible Wide Band Oxygen Sensors, the deck-molding such as maintenance to can be controlled within 0.5m, and two
End chamber combines with truss railing and undertakes longitudinal pedestrian load, and span can be to 35m, the case where other Auxiliary supports are added
Bigger can also be reached, chamber part reinforcement prevents unstability, top bearing plate from maintaining bridge deck to stablize with cross member, and lateral structure
Steel plate back cover can be used in the part bottom later stage.
Girder top uses truss-like railing, and banister top is led to using steel side or the handrail steel member of rectangular steel pipe composition,
It is connected using lattice format truss member between handrail steel member and bridge floor, had not only ensured its truss stress, but also lattice format purlin can be passed through
Hack lever part moulds a kind of three-dimensional contouring of entanglement line type.
In conclusion the combination stress of steel braced girder composite structure obtained by the present invention, steel construction girder and truss-like railing,
Both the bearing capacity and frequency comfort of bridge had been increased, and can effectively maintain its span ability, with traditional Steel Continuous Box beam
0.4m ~ 0.5m is reduced to by 0.8m ~ 1.5m compared to girder height, but greatly reduces the structure height of girder, top can be saved
About 30% quantities of structure and construction investment, while the changeable lattice grid pattern of lattice format truss member structure composition forms the rhythm very
A kind of strong artistic style, improves the landscape effect of bridge.
Description of the drawings
Fig. 1 is the front view of the present invention.
Fig. 2 is the side view of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes.
Embodiment 1.
As shown in Figs. 1-2, the steel braced girder composite structure of the present embodiment description, including steel construction girder 1, the steel construction
Girder 1 includes cross member 4, is equipped with top bearing plate 5 on 4 top of cross member, is symmetrically arranged in the both sides of cross member 4
The side chamber 3 of longitudinal stress is participated in, 3 top of side chamber is equipped with the truss-like railing 2 for participating in stress, the truss-like
Railing 2 includes handrail steel member 8 and lattice format truss member 9, and defence steel member is made of rectangular steel pipe, lattice format truss member
9 form Fence structure between handrail steel member 8 and side chamber 3, and 9 upper end of lattice format truss member and handrail steel member 8 are solid
Fixed connection, 9 lower end of lattice format truss member is fixedly connected with side chamber 3.
Wherein the lattice format truss member 9 is two-row structure, as shown in Fig. 2, two rows of lattice format truss members 9 prolong side
3 direction of chamber extend, and inclined direction on the contrary, composition visual effect be braiding structure three-dimensional contouring, it is this to be reversed
Lattice format truss member 9 do not only reach increase three-dimensional contouring artistic style purpose, moreover it is possible to ensure lattice format truss member 9
Force stability, by being transmitted on handrail steel member 8 for the uniform force of side chamber 3.
In order to ensure the stability of bridge floor, in the side chamber 3 and lower part of top bearing plate 5, which is equipped with, increases local stiffness
