Abstract
The utility model discloses a bidirectional cable stayed cylindrical tower cable stayed bridge which comprises a guyed tower fixed in the middle of the bridge. Front and rear sides of the guyed tower are towards the head of the bridge; left and right sides of the guyed tower are towards the side of the bridge; longitudinal stay cables are arranged on both the front and rear sides of the guyed tower and connected with a bridge floor; planes of the longitudinal stay cables are perpendicular to the left and the right sides of the guyed tower; the bridge is characterized in that transverse stay cables are arranged on both the left and right sides of the guyed tower and connected with the bridge floor; and the transverse stay cables are perpendicular to the left and the right sides of the guyed tower. The bridge has the obvious effects that the mature basic mechanical principle of plane triangular truss of for cable stayed bridge longitudinal cable stayed beam lifting and tower fixing in terms of structural design concept, and the basic mechanical principle is applied to the longitudinal and transverse design of main bridge and main tower, space tower cable tension is formed, and pressed longitudinal and transverse high efficiency structural systems of a main tower column reduce the engineering work load and the work load of the bridge.
Description
Technical field
The utility model belongs to a kind of bridge construction, specifically, is a kind of two-way oblique stay column shape pylon cable-stayed bridge.
Background technology
The maximum characteristics of two-way oblique stay column shape pylon cable-stayed bridge are to utilize the draw of bridge cable, bridge is fixed on the water surface, saved the bridge pier of bridge, two-way oblique stay column shape pylon cable-stayed bridge comprises the guyed tower that is fixed on the bridge middle part, the front and back sides of guyed tower is towards the end of the bridge of bridge, the left and right side of guyed tower is towards the bridge limit of bridge, all led vertical suspension cable at the front and back sides of guyed tower and has been connected with bridge floor, and the plane at described vertical suspension cable place and the left and right side of guyed tower are perpendicular.
But since vertically suspension cable be along bridge move towards hold bridge floor owing to only possess traction effect longitudinally.Therefore, guyed tower need be made Double-Tower Structure, as shown in Figure 1, from the vertical suspension cable of double tower traction, its engineering quantity and workload are excessive.
The utility model content
The purpose of this utility model provides a kind of two-way oblique stay column shape pylon cable-stayed bridge, and guyed tower is possessed vertically and horizontal traction effect, can reduce the engineering quantity and the workload of bridge.
For achieving the above object, the utility model provides a kind of two-way oblique stay column shape pylon cable-stayed bridge, comprise the guyed tower that is fixed on the bridge middle part, the front and back sides of guyed tower is towards the end of the bridge of bridge, the left and right side of guyed tower is towards the bridge limit of bridge, all having led vertical suspension cable at the front and back sides of guyed tower is connected with bridge floor, the plane at described vertical suspension cable place and the left and right side of guyed tower are perpendicular, its key is: all led horizontal suspension cable on the left and right side of described guyed tower and be connected with bridge floor, described horizontal suspension cable parallels with the left and right side of described guyed tower.
Vertically suspension cable and horizontal suspension cable combine, and guyed tower is possessed vertically and horizontal traction effect, have improved the stability of the body of a bridge.Make the guyed tower of two-way oblique stay column shape pylon cable-stayed bridge change single body of the tower structure into by the double tower body structure.
The basic mechanical principle of having used ripe cable stayed bridge vertically tiltedly to draw the plane trigonometry truss of bale handle Gu Ta, and with it apply to main bridge king-tower vertically and transverse design, formed space Tasso tension, the vertical and horizontal space high efficiency structural system of king-tower post pressurized.The engineering quantity and the workload of two-way oblique stay column shape pylon cable-stayed bridge have been reduced.
The bottom of described guyed tower is fixed with down trapezoidal base, should the seat of falling the trapezoidal bottom be positioned at the below of the described bridge body of a bridge, and described vertical suspension cable falls trapezoidal base with this and is connected.
Fall the design of trapezoidal tower seat not only for the guyed tower substructure provides effective intensity and rigidity, and with traditional tower relatively, Foundation Design is effectively reduced under the safe condition guaranteeing.
Remarkable result of the present utility model is: a kind of two-way oblique stay column shape pylon cable-stayed bridge is provided, the basic mechanical principle of having used ripe cable stayed bridge vertically tiltedly to draw the plane trigonometry truss of bale handle Gu Ta from the structure design theory, and with it apply to main bridge king-tower vertically and transverse design, formed space Tasso tension, king-tower post pressurized vertically and horizontal space high efficiency structural system, reduced the engineering quantity and the workload of bridge.Its concrete advantage is as follows:
One, guyed tower structure collectivity and core texture unit strength assurance coefficient height thereof are guaranteed bridge safety.
Two, the guyed tower vertical cross stiffness is big, has improved quiet, the power behavior of big bridge construction.
Three, king-post main body pressure-bearing, the king-post required size reduces greatly, and then can reduce branch space in the case beam, reduces beam body steel work consumption and shortens transition length of access bridge flat linearity etc.
Four, construction is simple, convenient, and exquisite succinct king-post facade and section have greatly improved the efficient of main tower of bridge construction, and the stressed approach of work progress clear in structure is guaranteed the safety of work progress.
Five, the disposable input of engineering reduces: king-post efficiently, Tasso efficiently, fall reasonable king-tower basis due to the trapezoidal king-tower pedestal, branch space and simple and clear repeatable construction bring not little saving all for the one-time investment of bridge in the case beam of optimizing, compare with traditional tower, the construction investment saving can reach more than 30%, saves the later stage maintenance costs greatly.
