Description

Technical Field

[0001] The utility model relates to the technical field of anchorages, in particular to a load-bearing member for anchoring a flexible suspension cable. Background Art

[0002] The prestressed flexible suspension bracket adopts a suspension system with a prestressed anchor structure as the core. It is mainly composed of prestressed cables, steel cable beams, cable trusses, etc. It can make adaptive adjustments according to changes in terrain to improve the adaptability of the project and the flexibility of construction. The flexible suspension structure resists the action of external loads by axial tension of the cable, which can make the most of the high tensile strength of steel, and has the characteristics of light structural weight and material saving. The prestressed flexible suspension bracket has high structural strength performance and stable structure. It solves the problems of easy distortion of large-span and high-headroom components and insufficient bracket strength. It is widely used in large-span and high-headroom occasions such as sewage treatment plants, fish-light complementarity, and ground photovoltaic power generation. The anchor plays a vital role in the flexible suspension anchor system.

[0003] The anchoring efficiency of traditional anchors in suspension anchoring systems of different spans is different. The anchoring force loss is large in small spans and small in large spans, but the adjustability is still insufficient. At the same time, the traditional single-hole prestressed anchor does not have the effect of preventing wind vibration in the field of flexible suspension cables. Under the action of live loads such as wind loads, fatigue failure such as loosening of clips may occur, posing a great safety hazard. Therefore, a load-bearing member for flexible suspension anchoring is proposed. Utility Model Content
