Abstract
The utility model discloses a guyed form traveler arc-shaped head adopted in cable stayed bridge construction, which comprises longitudinal beams (3), wherein the two longitudinal beams (3) are overlapped in the vertical direction, i.e. the double-longitudinal-beam structure is adopted, a steel box (5) with a stiffening plate (4) is arranged between the two longitudinal beams (3) arranged at both sides in the horizontal direction, the outer side of the longitudinal beams is provided with a baffle plate (9), and a pad beam (10) is arranged between the baffle plate (9) and an anchor beam (8). The guyed form traveler arc-shaped head successfully solves the technical problem that when a cable stayed bridge with the cable surface in a space curved surface adopts the guyed form traveler for construction, the guyed form traveler arc-shaped head structure needs to adapt to angle changes of stay cables in each beam section in the longitudinal bridge direction and the transverse bridge direction and needs to be capable of balancing the transverse component force. The guyed form traveler arc-shaped head is suitable for construction of the cable stayed bridge with the cable surface in the space curved surface.
Description
Technical field
The utility model relates to a kind of dragging suspension basket arc head that adopts in CONSTRUCTION OF CABLE-STAYED BRIDGE.
Background technology
In the past, adopted the cable stayed bridge of dragging suspension basket construction, be generally single rope face or double plane cable stayed bridge, promptly its suspension cable in one or two regular plane, the simple structure of Hanging Basket arc head.Current, bridge construction is constantly weeded out the old and bring forth the new, and is the cable stayed bridge of arch for Sarasota, and promptly its suspension cable arranges it no longer is the plane of rule, but space curved surface.When the cable stayed bridge of Spatial Cable face adopted the dragging suspension basket construction, the first structure of existing Hanging Basket arc was no longer suitable.
The utility model content
The technical problems to be solved in the utility model is: a kind of dragging suspension basket arc head is provided, and is arch or other polymorphic structure to adapt to Sarasota, and the rope face is the CONSTRUCTION OF CABLE-STAYED BRIDGE needs of space curved surface, overcomes the deficiencies in the prior art.
The utility model is by the following technical solutions: in 3 stacks of two longerons of vertical direction, promptly adopt two longitudinal beam structures; The steel case 5 of band stiffener 4 is set between two side girders 3 in the horizontal direction; At the arranged outside baffle plate 9 of longeron 3,8 of baffle plate 9 and anchor beams are provided with bearing beam 10.
Adopt between the steel case (5) of band stiffener (4) and horizontal direction two side girders (3) and be welded to connect; Adopt between baffle plate (9) and the longeron (3) and be welded to connect; Between baffle plate (9) and the bearing beam (10), adopt bolt to be connected between bearing beam (10) and the anchor beam (8).
Anchor beam (8) upper surface is close to steel case (5) arc face, the axis normal of soffit and beam section suspension cable (1).
During the first design of Hanging Basket arc, adopt two longerons as main force structure, the arc length of longeron and horizontal spacing satisfy respectively suspension cable in each beam section construction vertical bridge to the angle amplitude of variation of direction across bridge.The steel case of band stiffener is set between two longerons, pulling force is delivered to two side girders.The geometric position of suspension cable is provided with cable guide pipe respectively during by each beam section construction, is convenient to hard tension rod and passes.In the first lower end of Hanging Basket arc, by the anchoring temporarily position of each beam section suspension cable anchor beam is set respectively, the first arranged outside baffle plate of arc is provided with bearing beam between baffle plate and anchor beam, and the transverse component of avoiding stretch-draw to produce causes that anchor beam produces laterally and slides.
For Sarasota is arch or other polymorphic structure, the rope face is the cable stayed bridge of space curved surface, when adopting the dragging suspension basket construction, the first structure of arc is wanted to adapt to each beam section suspension cable and is changed to the angle with the direction across bridge both direction at vertical bridge, thereby when realizing each beam section construction, the Hanging Basket front fulcrum all can utilize the corresponding suspension cable of this beam section, and can balanced transversal component.
The utility model is applicable to the Spatial Cable face, it has successfully solved for the rope face is the cable stayed bridge of space curved surface when adopting the dragging suspension basket construction, and the first structure of Hanging Basket arc is wanted to adapt to each beam section suspension cable and changed and requirement that can balanced transversal component to the angle with the direction across bridge both direction at vertical bridge.The first structure stress of this Hanging Basket arc is reasonable, and constructing operation is easy, and can guarantee construction safety.

The specific embodiment
Dragging suspension basket arc head, it comprises two longerons 3, stiffener 4, steel case 5, cable guide pipe 6, anchor beam 8, baffle plate 9, bearing beam 10.According to the axis geometric position of each beam section suspension cable 1 in the bridge design, count suspension cable in the construction of each beam section vertical bridge to the angle amplitude of variation of direction across bridge.During first 2 designs of Hanging Basket arc, adopt two longerons 3 as main force structure, the arc length of longeron and horizontal spacing satisfy respectively suspension cable in each beam section construction vertical bridge to the angle amplitude of variation of direction across bridge.The steel case 5 of band stiffener 4 is set between two longerons, pulling force is delivered to two side girders.The geometric position of suspension cable is provided with cable guide pipe 6 respectively during by each beam section construction, is convenient to hard tension rod 7 and passes, and when stiffener conflicts with the cable guide pipe position, suitably adjusts cable guide pipe 6.In the first lower end of Hanging Basket arc, by the anchoring temporarily position of each beam section suspension cable anchor beam 8 is set respectively, the first arranged outside baffle plate 9 of arc, 8 of baffle plate 9 and anchor beams are provided with bearing beam 10, and the transverse component of avoiding stretch-draw to produce causes that anchor beam 8 produces laterally slip.
