Embodiment Construction

[0025] In the following, the present invention will be specifically described through exemplary embodiments. It is to be understood, however, that elements, structures and characteristics of one embodiment may be beneficially incorporated in other embodiments without further recitation.

[0026] see figure 2 , shows a stainless steel pull-sling device 20 for a bridge according to an embodiment of the present invention, which is arranged on a pull-sling bridge. Specifically, the pull sling device 20 includes: a pull cable for bearing tension, and the pull cable is formed by a collection of stainless steel wires; a tension end anchor 21 and a fixed end anchor 22 are respectively used to cooperate with anchors on the pull cable. The two ends are used to transmit the cable force of the stay cable; and the guard 23 is connected between the anchor 22 at the fixed end and the anchor 21 at the tension end, and is used to protect the exposed part of the stay cable outside the anchor....

Abstract

The invention discloses a stainless steel pulling cable device for a bridge. The stainless steel pulling cable device is arranged on a pulling cable bridge and comprises a cable for bearing tension, a fixed end anchor, a tensioning end anchor and a protective member. The cable is integrated of stainless steel wires; the fixed end anchor and the tensioning end anchor are respectively used for anchoring the cable in matched mode and transmitting the cable force; and the protective member is connected between the fixed end anchor and the tensioning end anchor and used for protecting the part of the cable exposed out of the anchors. The stainless steel pulling cable for the bridge has the good performance of rust protection, corrosion resistance and abrasion resistance and has long service life.

Description

technical field [0001] The invention relates to a pulling sling device, in particular to a stainless steel pulling sling device for a bridge. Background technique [0002] Bridges are highways, railways, canals, and other space structures that cross obstacles such as deep mountains, canyons, rivers, bays, etc., and have carrying capacity. They are the guarantee for smooth routes and the throat of transportation. Among them, long-span cable-stayed bridges have been widely and rapidly applied and developed due to their beautiful appearance and large spanning capacity. [0003] As the main load-bearing component of the cable-stayed bridge, the sling is very slender in section, which makes it the most sensitive component in this type of bridge system. Among the cable-stayed bridge diseases discovered so far, the disease of the cable-stayed bridge appears in the accounted for the vast majority. In recent years, many bridges at home and abroad have had to be replaced due to seri...
