Problems solved by technology

In order to ensure the installation accuracy of the outer casing, guide strips of a certain length or usually installed can be installed at a certain distance on the surface of the stay cable as a guide structure for installing the outer casing. The installation of the guide strips needs to be installed after the stay cables are stretched , so it is necessary to use special equipment for precise installation, but there is no related method and precise installation equipment for guide strip installation

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1~3 , a stay cable guide bar installation structure, the installation structure of this embodiment surrounds the stay cable 1, and can adjust the axial, radial and circumferential positions along the stay cable 1, while accurately installing the guide bar onto stay cable 1. It includes a guide frame 2 looped on the stay cable 1 and a construction platform 3 that can be driven by a traction device and can move axially along the stay cable 1. The construction platform 3 is used by construction personnel.

[0029] Such as Figure 1~2 As shown, the guide frame 2 of this embodiment is a support frame that surrounds the stay cable 1. The guide frame 2 is provided with a base body 6 along the axial lower end of the stay cable 1. The base body 6 surrounds the stay cable 1. The base body 6 One end is hingedly connecte...

Abstract

The invention relates to the technical field of the mounting of stay cables, in particular to a mounting structure and method for a guide bar of a stay cable. The mounting structure comprises a guideframe and a construction platform, wherein the guide frame sleeves the stay cable; the construction platform can be driven by a traction device to move in the axial direction of the stay cable; the guide frame is hinged to the construction platform in a manner that the guide frame can be rotated around the axis of the stay cable; a welding device for welding the guide bar to the outside of the stay cable is arranged on the guide frame; and a circumferential adjusting device for driving the guide frame to rotate around the axis of the stay cable is arranged between the construction platform andthe guide frame. The mounting structure for the guide bar, provided by the invention, has the advantages of simplicity, high efficiencies and precisions of welding and mounting, simple welding and mounting processes and low input costs of human and material resources, greatly facilitates the operation of constructors, and has great promotion value.

Description

technical field [0001] The invention relates to the technical field of stay cable installation, in particular to a stay cable guide bar installation structure and an installation method. Background technique [0002] The cable-stayed cable structure is mainly used in cable-stayed bridges and high-tower buildings. In addition to being a force-bearing structure, it also serves as a carrier for decoration, landscape and other structures. For example, installing lamps on the cable-stayed cables can provide lighting , It can also be used as a lighting landscape site. As a relatively mature product at home and abroad, stay cables have relevant standards and specifications for their design and manufacture. When installing appendages on the surface of the stay cables, generally the anti-corrosion capability and protection measures of the original structure cannot be reduced to avoid reducing the original life of the stay cable structure. Therefore, an outer sheath with a certain t...
