Description
Technical field
The present invention relates to bridge technology fields, and in particular to a kind of cable stayed steel truss co-operative system bridge.
Background technique
There are many bridge-type structure suitable for 300~500m across footpath, almost contain steel truss beam bridge, cable-stayed bridge, suspension bridge
With all bridges including arch bridge, still, the bridge construction natural conditions that each bridge type has it applicable, if any thrust arch bridge and ground again
Anchor suspension bridge is not suitable for soft soil foundation geological conditions, and when there is harsh limit for height to require, conventional cable-stayed bridge, arch bridge are even outstanding
Cable bridge is unsuitable for since bridge tower, arch rib all can be beyond limit for height requirements.
Comparatively, Steel Truss Beam structure height is low, can be used for the big or middle span bridge of limited high request, still, steel truss
Bridge set a roof beam in place on landscape and many people cannot be allowed to please oneself.Steel truss beam bridge is a more traditional bridge type, early in 1889
Year, Fox bridge was achieved that the leap of 521m, and the port bridge across footpath that Japan in 1974 builds up also has reached 510m.
But traditional truss-type bridges rod piece is intensive, and visual effect is undesirable, it is mainly manifested in the following aspects:
(1) rod piece is more, vision is in disorder；
(2) it is controlled, is withstood forces smaller by bar stability；
(3) difficulty of construction is big for main span range on river surface；
(4) cost is larger, economical poor.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of beautiful, endurance more
Strong cable stayed steel truss co-operative system bridge.
The purpose of the present invention can be achieved through the following technical solutions: a kind of cable stayed steel truss co-operative system bridge, packet
Main span and end bay are included, the main span lower part is equipped with middle pier, and steel truss cantilever beam is arranged in the end bay of the bridge, and the steel truss is outstanding
Setting drag-line suspension cable and its bridge floor of bearing in the middle part of arm beam and main span.The present invention is by traditional steel truss beam bridge and cable-stayed bridge knot
It closes, power performance more better than cable-stayed bridge conventional under the same terms can be obtained, improve its wind resisting stability.
The steel truss cantilever beam includes bridge floor upper and lower part, the two sides parallelogram on bridge floor top, and
Two bevel edges of the parallelogram in the vertical direction extend to main bridge center from bottom to top, and bridge floor lower part is in the shape of the letter V,
And lower part is fixed on middle pier by support.I.e. rigid truss uses large scale section chord member, and truss lower edge is connected altogether with main deck
Same stress has steel truss cantilever beam powerful each to rigidity, while providing for across oblique pull part broad in the middle strong
Anchoring；Meanwhile the rigid truss in bridge floor lower part uses V-structure, increases truss root deck-molding, and it is anti-to effectively increase cantilever truss beam
Curved rigidity, stress need and moulding perfect combination.The truss of gathering can be by seat supports on main pier bearing platform, convenient for adopting
It takes and subtracts vibration isolation measure.
The ratio between described end bay and main span are 0.25~0.65.
The side and steel truss cantilever beam top of span centre bridge floor are separately connected positioned at the both ends of the drag-line of the top
Tip triangular area.
Height more than the steel truss cantilever beam bridge floor is 20~40m, the specific longest for regarding oblique pull bridge floor in the middle part of main span
The angle of drag-line and horizontal plane it is unsuitable it is too small depending on.
The center of host bridge is equipped with expansion joint and rigid hinge, to transmit longitudinal and transverse bridge to moment of flexure and shearing, release temperature
Power.
Compared with prior art, the beneficial effects of the present invention are embodied in following several respects:
(1) traditional steel truss beam bridge and cable-stayed bridge are combined, can when not needing that towering bridge tower is arranged cloth
The main span bridge floor for setting suspension cable bearing, especially suitable for the Large Span Bridges for thering is aviation limit for height to require；
(2) steel truss cantilever beam has powerful each to rigidity, while providing for across oblique pull part broad in the middle strong
Anchoring.Power performance more better than cable-stayed bridge conventional under the same terms can be obtained, its wind resisting stability is improved.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention；
Wherein, 1 is main bridge, and 2 be access bridge, and 3 be handover pier, and 4 be middle pier, and 5 be steel truss cantilever beam, and 51 be top, and 52 are
Lower part, 6 be drag-line, and 7 be expansion joint and rigid hinge.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
A kind of cable stayed steel truss co-operative system bridge, as shown in Figure 1, the bridge includes main bridge 1 and connects with main 1 both ends of bridge
The access bridge 2 connect sets there are two middle pier 4 in the middle part of main bridge 1 in main bridge 1 and 2 junction of access bridge setting handover pier 3, joins 3 He of pier
The distance between middle pier 4 is 160m, and total across footpath of main bridge 1 is 785m.The both ends of main bridge 1 are equipped with 5 structure of steel truss cantilever beam,
The V-shaped structure of parallelogram sturcutre and lower part 52 including top 51 is equipped with drag-line between 51 inner end of top and main bridge 1
6, expansion joint and rigid hinge 7 are equipped in the middle part of main bridge 1, to transmit longitudinal and transverse bridge to moment of flexure and shearing, release temperature power.
Specifically:
