Description
Technical field
Cable support device technical field is the utility model is related to, more specifically to a kind of anticorrosive plastic-steel cable support
Frame.
Background technology
As economic construction of China and scientific and technical develop rapidly, electric power, communication and communications and transportation etc. are set up in field
The demand of cable increasingly improves, and during cabling, installation cable tray is intersected usually on cable duct two side, with
This supports cable.For a long time, the cable tray main selection product as cabling always made of angle steel, this be because
Be angle steel by roll forming, have the characteristics that it is economical, be easy to get.
But the weakness of angle bracket is also obvious, especially under the conditions of many rugged environments, such as subway, tunnel
The occasions such as road, chemical enterprise, rainy moist or coastal salt fog, sultry, moist environment easily causes angle bracket in cable duct
Corrosion, reduce the service life of cable tray, also increase the maintenance cost of facility.Although at present use outer painting more
Or the technology diagonal steel such as galvanizing bracket carries out surfacecti proteon processing, but still corrosion cannot be solved the problems, such as well, seriously affect
The safety and trouble-free life of the facilities such as electric power, communication.
Pass through patent retrieval, Chinese Patent Application No.：201620591318.6 the applying date：On June 15th, 2016, invention
Create entitled：A kind of detachable cable stent, this application include angle steel trailing arm, channel steel stent and supporting steel plate；Channel steel branch
