Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge construction, relates to the installation of arch ribs of arch bridges by adopting an oblique-stayed buckle-hanging method, and specifically relates to a buckle-back cable tensioning connector of an oblique-stayed buckle-hanging system. Background Art
[0002] When installing the arch ribs by the inclined buckle hanging method, it is usually necessary to set up a buckle tower, with a buckle cable connected between one side of the buckle tower and the arch rib, and a back cable connected between the other side and the anchor. An anchor box is installed on the buckle tower, and the tensioning end of the buckle back cable is connected to the anchor box at the top of the buckle tower, and the buckle back cable is tensioned on the buckle tower. However, in the case of steep mountains on both sides, it is impossible to set up a buckle tower, and the anchor needs to be set on the hillside, and the buckle cable is directly connected between the anchor and the arch rib. In this case, the tensioning end of the buckle cable is generally set on the anchor, and for this purpose, a tensioning anchor box needs to be set on the anchor, resulting in a more complicated structure of the anchor anchor support; and even if there is a buckle tower, tensioning operations are performed on the top of the buckle tower, and there is a certain risk of high-altitude operations. Summary of the invention
[0003] The utility model aims to solve the above problems and provides a back-cable tensioning connector for being installed on an anchor to facilitate tensioning of the back-cable on the anchor.
[0004] The technical solution of the utility model is as follows:
[0005] A back-clip cable tensioning connector, characterized in that it includes a tensioning anchor box, an articulated anchor box and two steel slings, the tensioning anchor box includes two first steel plates arranged in parallel, two connecting plates are welded between the opposite side walls of the two first steel plates, a tensioning anchor pad is welded between the lower ends of the two connecting steel plates, and a cable hole is provided in the middle of the tensioning anchor pad; the articulated anchor box includes two second steel plates arranged in parallel, two articulated ear plates are welded between the two second steel plates, and one end of the two articulated ear plates is provided with an axial hole that penetrates through; the tensioning anchor box and the articulated anchor box are arranged opposite to each other, the tensioning anchor pad of the tensioning anchor box faces the articulated anchor box, and the two articulated ear plates of the articulated anchor box are provided with an axial hole with one end extending away from the tensioning anchor box; one end of the two steel slings is respectively welded to the two first steel plates of the tensioning anchor box, and the other end is respectively welded to the two second steel plates of the articulated anchor box, and the two steel slings are respectively arranged on the outside of the two connecting plates and the two articulated ear plates.
[0006] The utility model has a simple structure and is easy to install. It can be hinged with the ear plate on the anchor seat without changing the anchor seat structure. The utility model has the functions of connecting and tensioning the back cable. It can be installed on the anchor and tensioning operations can be performed on the ground. Therefore, even in the case of a buckle tower, the tensioning end of the back cable can be set on the ground by adopting the utility model, avoiding the risk of high-altitude operations.
