Cable pipe sleeve suitable for cable structure system, multi-functional outer casing pipe containing cable pipe sleeve and cable structure

Abstract

The invention discloses a cable pipe sleeve suitable for a cable structure system, a multi-functional outer casing pipe containing the cable pipe sleeve and a cable structure. The cable pipe sleeve suitable for the cable structure system comprises a cable pipe sleeve body, the cable pipe sleeve body is spliced by a plurality of assembly units arranged in the circumferential direction of the cablepipe sleeve body,one or more installation structures for installing function units are machined on the pipe walls of one or more assembly units, and the installation structures comprise installation grooves which are formedin the axial directions of the assembly units at intervals and connecting holes for communicating the installation grooves. According to the cable pipe sleeve suitable for the cable structure system, the multi-functional outer casing pipe containing the cable pipe sleeve and the cable structure, the structure is simple, use is convenient, by designing the cable pipe sleeve body as the assembly units which can be mutually spliced in the circumferential direction and the radial direction of the cable pipe sleeve body, it is ensured that the assembly units are independent of oneanother, and thus the cable pipe sleeve is transported, assembled and replaced conveniently.

Description

technical field [0001] The invention relates to a cable sleeve structure, which belongs to the technical field of cable structures, in particular to a cable sleeve suitable for a cable structure system, an outer sleeve containing the cable sleeve structure and a cable structure. Background technique [0002] The cable structure refers to the prestressed structural system formed by the cable as the main load-bearing member. It is mainly used in cable structures such as stay cables in bridges, main cables, suspenders, and stay cables in other building structures. Bridges and other buildings using cable structures have the characteristics of beautiful shape, simplicity, clarity, perfect combination of rigidity and softness, strength and beauty, etc., which give people a refreshing feeling. At the same time, the cable structure and the main structure set off against the surrounding environment, and will form the city's sightseeing spots and landmarks. At present, the cable str...

AI Technical Summary

Problems solved by technology

[0003] 1. For lighting units installed on bridges and other buildings, it is often difficult to control the lighting units due to difficult or impossible wiring

The lamps and cables of some cable structure lighting units are directly installed on the surface of the cable structure, which will greatly shorten the life of the cable structure and lighting unit

[0004] 2. In winter, icing may occur on the cable structure. When the ice melts, it is easy to cause damage to passing vehicles and pedestrians, causing safety accidents

[0005] 3. When the bridge and other buildings are relatively high and the cable structure is relatively long, natural factors such as temperature, humidity, sunshine, wind speed between the cable structures, and cable structure characteristics such as the amplitude and vibration frequency of the cable structure are difficult to measure

[0007] 5. When a fire occurs outside the main structure, it may cause burning or damage to the cable structure, reduce the service performance and life of the cable structure, and cause safety accidents

This structure needs to increase the bracket, on the one hand, the weight of the stay cable, on the other hand, due to the space between the sleeve and the stay cable, the cross-sectional area of ​​the stay cable system is increased, and the wind resistance of the stay cable is increased at high altitude. At the same time, the hollow part causes the bearing capacity of the sleeve to decrease, which may cause damage and deformation of the sleeve under external loads, such as wind, snow, etc., and reduce the service life.
