Embodiment Construction

[0021] The present invention is an ultra-high-strength parallel steel wire durable cable. The structure of the finished cable is shown in FIG. The anchorage 2 is formed by connecting an anchor cup 2.3, an anchor ring 2.4 and a connecting cylinder 2.6.

[0022] The cross-section of the steel strands of the cable is closely arranged in a regular hexagon or a hexagon with missing corners, and is formed by twisting. There are two types of cable body structures, and the cross-sectional schematic diagrams are shown in Figure 2 and Figure 3 respectively.

[0023] Referring to Figure 2, the outer surface of the steel wire bundle 1.2 of the cable body 1 is first wound with a perfluorinated film tape 1.3, then wound with a fiber reinforced polyester tape 1.4 to form, and then extruded a double-layer high-density polyethylene sheath 1.5, and the surface of the cable body is sealed. The embossing process forms embossed indentations 1.6.

[0024] Referring to Fig. 3, the gap between the ...

Abstract

An ultrahigh-strength durable pull cable made of parallel steel wires is composed of the cable body consisting of central parallel steel wires, fluorized rubber belt layer winding around said steel wires, fibre reinforced polyester band layer and high-density polyethene jacket, and the archors at both ends of cable body. Its advantages are high anticorrosion power and long service life.

Description

Technical field: [0001] The invention relates to a cable, in particular to an ultra-high-strength parallel steel wire durable cable. It is mainly used for cable-stayed bridges as cable-stayed cables. Background technique: [0002] The cable-stayed bridge is a self-anchored structural system, which does not require huge and expensive anchor piers at both ends of the cables, and its cable stress is basically constant along the cable length. Cable-stayed bridges are arranged in a straight line within the span and have considerable tensile stiffness. The stay cables exert favorable pressure on the main girder of the bridge span structure, which improves the stress state of the main girder. Cable-stayed cables have a great influence on cable-stayed bridges, and the failure of cable-stayed bridges in history is mainly caused by cable problems. Since the stay cables are generally arranged outside the beam body and are under high stress for a long time, their cross-sectional dime...
