Example Embodiment

[0040] In the accompanying figures, in a non-limiting way, one embodiment of a force-transmitting member for a cable-strand anchor according to the present invention is illustrated (see image 3 ), which includes a force transmission member 10, a cable strand passing hole 18 with a tapered anchor hole 19 at the end, a force bearing surface 15, a main bearing surface 16 and an auxiliary bearing surface 17. The outline of the force transmission member 10 is roughly a hexahedron, and the force bearing surface 15, the main bearing surface 16 and the auxiliary bearing surface 17 are all one surface of the force transmission member 10; wherein the force bearing surface 15 and the main bearing surface 16 have no common side, and There is no parallel relationship, the auxiliary support surface 17 has a common edge with the main support surface 16 . The through hole 18 is a through hole located in the force transmission member 10, one outlet is located on the force bearing surface 15, ...

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...
