Problems solved by technology

[0010] The technical problem to be solved by the present invention is that in the current suspension cable-cable-stay cooperation system, there is an obvious discontinuity in the deformation and internal force in the connection area between cable-stay and suspension. Resulting in poor structural security, basically impossible to implement

Embodiment Construction

[0034] In the accompanying drawings, in a non-limiting manner, an embodiment of a strand anchorage related to the present invention is illustrated (see FIG. 4), which includes a force transmitting member 10, a clip 12 and Anti-exit device 13. Wherein, the passage hole of the force transmission member 10 includes a tapered hole near the outlet of the force-bearing surface of the force transmission member, and the clip 12 is located between the tapered hole and the surface of the strand 14 that passes through the hole, and the anti-exit device 13 is connected with the force transmission member 10 by bolts, and has the function of preventing the clip 12 from withdrawing from the tapered hole. The implementation steps are: insert the cable strand 14 into the passage hole of the force transmission member 10, insert the clip 12 into the tapered hole at the end of the passage hole and tighten it, and then connect the anti-exit device 13 to the force transmission member 10 with bolts ...

Abstract

The invention discloses a suspended cable-cable-stayed cooperation system. A suspended subsystem of the suspended cable-cable-stayed cooperation system utilizes a sling 5 which is arranged in an inclined mode, and the sling 5 and a stay cable 4 close to a main tower 2 together provide elastic support for a main beam 1 evenly and continuously. Therefore, the problem that a roebling system and a terry dischinger system cannot be constructed because of obvious internal force and discontinuous deformation is resolved radically. The invention further provides a suspended cable structure combining the new regular pattern of internal force distribution of a main cable 3, the suspended cable enables parts of strands to be anchored close to the lower end of a cable clamp, and the problem that the cable clamp anti-sliding design is difficult is resolved. The suspended cable-cable-stayed cooperation system is clear in stress, good in power characteristic, safe, and reliable, saves material, and is beautiful in appearance, free of large anchorages and good geological conditions, strong in environment adaptability, suitable for suspended arm construction, excellent in spanning capability, and suitable for bridge engineering of middle-large spans in particular to oversized spans.

Description

technical field [0001] The invention belongs to the field of bridge structures, and relates to a suspension cable-cable-stay cooperation system, in particular to a suspension cable and an anchor clamp for the suspension cable. Background technique [0002] At present, the existing suspension-cable-stayed collaborative systems in the field of bridge structures include the Roeblin system and the Dissinger system. [0003] In the Roebling system, the suspension cables are arranged in the same way as the conventional suspension bridge in the longitudinal vertical facade, that is, they are all vertically arranged; only at each suspension cable symmetrical to the side span in the side span and main span , increase the arrangement of stay cables to play a strengthening role, stay cables are only an auxiliary component, and stay cables and suspension cables are not considered as equally important force-bearing components in the design. [0004] The famous German bridge designer Die...
