Integrally formed stainless steel cable bridge and preparation method thereof

Abstract

The invention discloses an integrally formed stainless steel cable bridge and a preparation method thereof in the technical field of cable fittings. The integrally formed stainless steel cable bridgecomprises a bottom plate, a left folded plate, a right folded plate, a left mounting plate and a right mounting plate. A left side wall of the bottom plate is integrally formed and is connected to theleft folded plate, and a right side wall of the bottom plate is integrally formed and is connected to the right folded plate. According to the integrally formed stainless steel cable bridge and the preparation method thereof, the cable bridge can be quickly and effectively prepared by the combination of accessories and the improvement of preparation process, the steps are simplified, a compression plate containing a top pad and a bottom pad is added inside, the strength and toughness of stainless steel are increased, the local settlement deformation of the stainless steel with strong ductility after bearing weight is avoided, the compression plate is made of expanded graphite powder which can be released from ports of a left folded side and a right folded side after being exposed to hightemperature, the internal space of the cable bridge is filled, the cable is protected, the risk of open flame combustion is reduced, the loss is effectively reduced, and the safety of information transmission is protected.

Description

technical field [0001] The invention relates to the technical field of cable fittings, in particular to an integrally formed stainless steel cable bridge and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulating covering layer, used in power system, information transmission and instrumentation system and other fields. [0003] The cable tray is one of the accessories in the cable installation process. The cable tray is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, brackets and installation accessories. The bridge in the building can be erected independently. , and can also be laid on various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simpl...

Problems solved by technology

[0005] The object of the present invention is to provide an integrally formed stainless steel cable bridge and its preparation method, to solve the problem that the existing cable bridge proposed in the above background technology needs to go through processes such as material selection, cutting, grinding, welding and assembling. It is cumbersome, and solder joints are easy to appear in the welding assembly, the degree of integration is low, and the compactness cannot be guaranteed. The cable tray using stainless steel as raw material, because stainless steel has certain ductility, strength and toughness are not high, subject to Local subsidence and loose connection will occur after the force is applied. Secondly, in the face of fire, the heating of the cable bridge under high temperature will cause the internal cable to overheat and burn from time to time, which has long become a problem of economic waste and safety of information transmission.
