Technical field
The invention belongs to bridge structure building fields, and in particular to a kind of half floats the cable-stayed bridge of truss-like bridge tower.
Background technique
With the increase of beam bridge span, need to take the additional ancillary measure such as suspension cable to meet structure stress requirement, But the temperature deformation of girder can also increase therewith, such as use prestressed concrete girder, and later period time deformation is also difficult to control, shadow Bridge floor driving ride comfort and comfort level are rung, especially to the driving demanding high-speed railway bridge of ride comfort.
Summary of the invention
The present invention proposes that the purpose is to provide a kind of half floating truss-like bridge tower in order to solve the problems existing in the prior art Cable-stayed bridge.
The technical scheme is that a kind of half floats the cable-stayed bridge of truss-like bridge tower, abutment pier including two sides and it is located at The bridge tower at middle part, the bridge tower middle part, abutment pier upper end are provided with support, are disposed on the support and directly bear bridge floor load Girder, arrange that multipair suspension cable, the bridge tower are separated with girder between the bridge tower, girder.
The bridge tower is the truss-like bridge tower of tower pier one, the separation of tower beam.
The bridge tower indulges bridge to being in A font, and bridge tower direction across bridge is in H font.
The support is longitudinally-moving support and bi-directional movable support, and bridge is indulged in the bridge tower to the two rows of supports of setting.
The longitudinally-moving support is arranged in route side, and bi-directional movable support is arranged in the route other side.
The abutment pier, bridge tower, girder form end bay, between the bridge tower, girder formed in across.
The girder is prestressed concrete box girder or girder steel.
The abutment pier, bridge tower are arranged with infrastructure, and the infrastructure is pile foundation, Extended chemotherapy, well foundation One of.
In described across for one across or collapse more.
Beneficial effects of the present invention are as follows:
The present invention uses space truss type bridge tower, and bridge tower longitudinal size is larger, effectively reduces Longspan Bridge infrastructure Cushion cap thickness and cubic amount of concrete, and modern design, beauty.
The present invention reduces girder temperature deformation, and efficiently solve by the two rows of longitudinal supports of setting on a bridge tower The uncontrollable problem of large-span concrete girder time deformation is conducive to the smooth of bridge floor driving especially high-speed railway driving Property and comfort level.
Full-bridge of the present invention is all made of longitudinally-moving support and bi-directional movable support, does not set hold-down support, seamless for being laid with Route across railroad bridge, can effectively reduce temperature span greatly, avoid deployment rails thermoregulator, reduce maintenance work Amount.

Specific embodiment
Hereinafter, referring to drawings and examples, the present invention is described in detail:
As shown in Figure 1 and 2, a kind of cable-stayed bridge of half floating truss-like bridge tower, the abutment pier 3 including two sides and the bridge tower positioned at middle part 2,2 middle part of bridge tower, 3 upper end of abutment pier are provided with support 4, and the master for directly bearing bridge floor load is disposed on the support 4 Beam 5 arranges that multipair suspension cable 6, the bridge tower 2 are separated with girder 5 between the bridge tower 2, girder 5.
The bridge tower 2 is the truss-like bridge tower of tower pier one, the separation of tower beam.
The bridge tower 2 indulges bridge in A font, and 2 direction across bridge of bridge tower is in H font.
The support 4 is longitudinally-moving support and bi-directional movable support, and bridge is indulged in the bridge tower 2 to the two rows of supports 4 of setting.
The longitudinally-moving support is arranged in route side, and bi-directional movable support is arranged in the route other side.
The abutment pier 3, bridge tower 2, girder 5 form end bay 7, between the bridge tower 2, girder 5 formed in across 8.
The girder 5 is prestressed concrete box girder or girder steel.
The abutment pier 3, bridge tower 2 are arranged with infrastructure 1, and the infrastructure 1 is pile foundation, Extended chemotherapy, open caisson One of basis.
In described across 8 for one across or collapse more.
Girder is end bay 7 between the abutment pier 3, bridge tower 2, and the end bay 7 is 94.2m long, main between the bridge tower 2, bridge tower 2 Liang Weizhong across 8, it is described in across 8 long 220m.
The girder 5 can be prestressed concrete beam or girder steel.
In the girder 5 across 8 can be one across or multispan.
The above tower height 35m in bridge tower Bridge 2 face, be in across 8 1/6.3.
Construction method of the invention is as follows:
Firstly, construction infrastructure 1, then construct bridge tower 2 and abutment pier 3, then rear erection support 4 and tower beam synchronous construction girder 5 Support on segment, then after the other segments of symmetrical Hanging Basket free cantilever casting girder 5 and tensioning correspond to segment prestressing force and suspension cable, then 5 midspan closing of girder, tensioning closure prestressed strands afterwards, then the attached construction of rear bridge floor, it is last to mend tensioning suspension cable as needed.
The present invention uses space truss type bridge tower, and bridge tower longitudinal size is larger, effectively reduces Longspan Bridge lower part base The cushion cap thickness and cubic amount of concrete of plinth, and modern design, beauty.By the way that two rows of longitudinal supports are arranged on a bridge tower, reduce Girder temperature deformation, and solve the problems, such as to be difficult to control compared with large span concrete girder time deformation, be conducive to bridge The ride comfort and comfort level of face driving especially high-speed railway driving.Using half floating system, full-bridge is all made of longitudinally-moving branch Seat and bi-directional movable support, do not set hold-down support, for being laid with gapless track greatly across railroad bridge, can effectively reduce temperature across Degree avoids deployment rails thermoregulator, reduces maintenance workload.
It only describes the invention in detail above, but content is only the preferred embodiment of the present invention, it cannot be by Think for limiting practical range of the invention.Any changes and modifications in accordance with the scope of the present application, should all be still It falls within the scope of the patent of the present invention.
