Abstract

The invention discloses a positioning assistive device and a hollow beam provided with the positioning assistive device, and relates to the technical field of guy rope hanging basket construction. Thepositioning assistive device comprises a body, a prism arranged on the body, two sliding cavities formed in the same side of the body and two abutting blocks, wherein the two sliding cavities are correspondingly formed in the left side and the right side of the prism, and the sliding cavities and the prism are correspondingly arranged on the two sides of the body; an elastic piece is connected tothe side wall, close to the other sliding cavity, of the sliding cavity; and the two abutting blocks are correspondingly and slidably assembled in the two sliding cavities and connected with the elastic piece, and part of the structures of the abutting blocks extend out of the sliding cavities. According to the positioning assistive device, the position of the hollow part of the hollow beam can be rapidly positioned and accurately measured.

Description

technical field [0001] The application relates to the technical field of dragline hanging basket construction, in particular to a positioning aid and a hollow beam equipped with the positioning aid. Background technique [0002] In the construction of the cable hanging basket on the bridge, it is necessary to locate the distribution beam on the curved head of the cable hanging basket, so as to install the cableway pipe extender, so that the force on the bridge deck can be controlled by the main cable through the cables in the cableway pipe. If the positioning of the hollow part on the distribution beam is inaccurate, the installation of the cableway pipe extender installed in the hollow part is also prone to deviation, which may lead to safety accidents in bridge construction. [0003] In the related art, the position of the hollow part of the distribution beam is often determined by measuring, calculating and checking multiple measurement points on the edge of the distribut...
