Steel strand integral bundle extrusion anchor cable guy cable

Abstract

The invention relates to a draw-rope used in major construction projects, in particular to an anchor draw-rope formed by compressing a whole bundle of stranded steel ropes and composed of a finished stranded steel rope body and anchor fasteners on the two ends. The anchor fastener is divided into an anchor fastening unit and a sealing unit. The anchor fastening unit comprises a compressing anchorage sleeve, a screw nut and an end cover. Mounting holes for embedding the stranded steel rope in equal number with the compressed stranded steel ropes are drilled inside the compressing anchorage sleeve; the stranded steel ropes are disposed in the mounting holes and compressed with the anchorage sleeve into a whole; main components of the sealing unit includes a sealing cylinder, a sealing ring and antiseptic materials. The end of the compressing anchorage sleeve is provided with external screw thread; one end of the sealing cylinder is sleeved on the end of the compressing anchorage sleeve through the screw thread; the sealing ring and a restraining ring sleeved on the rope body are arranged in sequence inside the other end of the sealing cylinder; a gland bush is screwed on the sealing cylinder through the inner screw thread of the sealing cylinder which is filled with antiseptic materials; a through-slit is opened between the mounting holes for embedding the stranded steel ropes inside the compressing anchorage sleeve. The stranded steel rope in the anchor rope is able to perform firm anchoring, not easy to slip off under high-frequency vibration, small in anchor head volume and low in manufacture cost.

Description

Technical field: [0001] The invention relates to a cable used in a large-scale construction project, which is a whole-bundle extruded anchor cable cable. Background technique: [0002] At present, the cables used in large buildings such as bridges and stadiums in my country mainly include cold-cast anchor cables, hot-cast anchor cables and clip-type anchor cables. However, the dragline of the extrusion anchoring method is hardly used because it is easy to slip off in practice. Due to the three forms of cold cast anchor, hot cast anchor and clip anchor cable, the size of the anchor head is relatively large, and the cost is relatively high. For this reason, the utility model patent whose application number is 03271782.2 discloses a cable in the form of a whole bunch of extruded anchor structure. Although it solves the problem that the anchor head size is relatively large and the cost is high, it still has the following deficiencies: [0003] 1. The entire length of the ancho...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide an improved steel strand extruded anchor cable, which can make each steel strand of the anchor cable receive sufficient extrusion force when extruded. , to solve the problems that the steel strands cannot be anchored reliably, are prone to slipping after being subjected to high-frequency vibrations, and the anchor heads in the existing three forms of cold-cast anchors, hot-cast anchors and clip anchor cables are large in size and high in production costs.
