Definitions

  • the present invention relates to cable trays, and more particularly, to a cable tray used in a wiring operation in which relatively heavy cables or pipes are distributed in a manufacturing plant, a vessel, a marine structure or the like.
  • a number of cables are used to supply power to a plant, a vessel, a marine structure or the like, which consume a large amount of electric power.
  • the cables are generally wired on the floor or the wall.
  • a cable tray is widely used to prevent a worker or a passerby from experiencing inconvenience due to the presence of the wired cables, or to prevent an accident from being caused by the cables.
  • Such a cable tray is divided into two types, i.e., an integrated type and a prefabricated type, according to the different kinds of the cables used.
  • a representative example of the integrated cable tray is disclosed in the following Document 1.
  • the integrated cable tray is mainly used to wire ordinary lightweight cables, and is manufactured with a plastic or thin steel sheet.
  • the integrated cable tray functionally enables convenient wiring and easy transport thereof.
  • the integrated cable tray of Document 1 causes a large waste of material, and when wired with heavyweight cables or pipes, fails to support them. For this reason, the use of the integrated cable tray of Document 1 has limited use.
  • a prefabricated cable tray is proposed and used.
  • side bars located on opposite sides of the cable tray are connected with crossbars (rungs) , which are arranged in a ladder shape at regular intervals.
  • the crossbars are bolted or welded to the side bars. Thereby, wasting of material is prevented, and the heavyweight cables or pipes are firmly supported when in the wired state.
  • the prefabricated cable tray is designed in such a manner that the crossbars are bolted or welded to the side bars, and this increases the number of manufacturing processes and has poor durability.
  • the paired side bars and the crossbars coupled with the side bars are previously prepared, and then the crossbars are bolted or welded to the side bars.
  • the number of manufacturing processes is excessively increased, compared with the integrated cable tray of Document 1.
  • joints of the crossbars and the side bars may be of weak durability. This makes for difficult long-term use. Furthermore, in the case of a vessel to which parts cannot be rapidly supplied, such weak durability poses a large burden.
  • an embodiment of the present invention provides a cable tray, which is directed to a reduction in the material used, is light weight and of high durability, thereby providing for easy installation of relatively heavyweight cables or pipes in a manufacturing plant, a vessel, a marine structure or the like.
  • Another embodiment of the present invention provides a cable tray, which is directed to a reduction in the number of manufacturing processes, a reduction in the amount of material used, is light weight and offers an improvement in durability.
  • a cable tray which includes: side bars arranged in a direction toward which a cable is wired; and cross bars continuously displaced to the side bars so that openings are formed between the cross bars; wherein the side bars are formed integrally with the cross bars in one body and are bent in one direction away from the cross bars.
  • side bars and crossbars are integrally formed by bending, so that welding, which has been mainly used in the conventional prefabricated cable tray, is excluded to reduce the number of manufacturing processes, and so that durability is improved and sagging is prevented.
  • each crossbar includes a perimetric reinforcing part or a central reinforcing part, so that the durability is further improved to provide firm support of relatively heavy cables or pipes.
  • the cable tray is subjected to zinc galvanizing, and thus has a plating layer and a passivation layer formed on the galvanized layer.
  • the quality of the exterior surface of the cable tray is good, and is protected against oxidation.
  • the cable tray has corrosion resistance, and thus an increased life span.

  • FIGS. 7 to 13 are perspective views illustrating several embodiments of a ladder type cable tray according to the invention, in which side bars are formed integrally with and bent upwards from cross bars.
  • FIG. 14 is a cross-sectional view illustrating an embodiment of a perimetric reinforcing part according to the invention, in which the perimetric reinforcing part is formed on and bent downwards from the perimeter of cross bars.
  • FIGS. 15 and 16 are cross-sectional views illustrating an embodiment of a central reinforcing part according to the invention, in which the central reinforcing part is formed in and bent upwards from the central portion of a cross bar.
  • a cable tray 1 of the invention includes side bars 10 and 11 and cross bars 20.
  • the cross bars 20 alternate with openings 21, and the side bars 10 and 11 are formed integrally with and are bent in one direction away from the cross bars 20.
  • the side bars 10 and 11 are arranged in the opposite sides of the cable tray 1 along the direction in which the cable tray 1 is constructed.
  • the side bars 10 and 11 are extensible in length.
  • the top portions of the side bars 10 and 11 are bent in one direction to form side reinforcing portions 12, thereby preventing the side bars 10 and 11 from warping, which would otherwise occur in the process of wiring the cables.
  • the side bars 10 and 11 include those which are generally formed straight or partially bent in and along the wiring direction of the cables .
  • the side bars 10 and 11 also include rounded structures since they may be used for an elbow that connects the straight cable tray 1.
  • the side bars 10 and 11 are provided in structures modified in light of environmental conditions under which the cable tray 1 of the invention is constructed.
  • the side bars 10 and 11 are arranged in the sides of the cable tray 1 in the wiring direction of the cables and are formed integrally with the cross bars 20, which alternate with the openings 21. Since the side bars 10 and 11 are bent upwards or downwards from the cross bars 20, the connecting portions of the cable tray 1 of the invention have an excellent and higher durability than those of the conventional prefabricated cable trays.
  • the openings 21 are laser-machined or press- machined so that the cable tray 1 of the invention can not only offer savings in the amount of material used but also can be of light-weight. Consequently, the cable tray 1, if installed in a vessel or a marine structure, can reduce the burden of the load.
  • the cable trays 1 of the invention as shown in FIGS. 1 to 6 are a new marine type cable tray, in which the side bars 10 and 11 are bent downwards from the cross bars 20.
  • the cable trays 1 as shown in FIGS. 7 to 13 are a ladder type cable tray, in which side bars 10 and 11 are bent upwards from cross bars 20.
  • the side bars 10 and 11 of this type of cable tray 1 are formed relatively higher than those of the new marine type cable tray 1 so as to more stably support cables.
  • the side bars 10 and 11 are formed straight as shown in FIGS. 7 to 10 and are rounded as shown in FIGS. 11 to 13.
  • the side bars 10 and 11 are connected integrally to and bent from the cross bars 20.
  • the cross bars 20 of the invention are repeatedly arranged with openings 21 interposed therebetween to be integrally connected with the side bars 10 and 11 while supporting a variety of cables.
  • the cross bars 20 are preferably made of metal since they support relatively heavy pipes and the like.
  • a plurality of vent holes 22 can be formed in the cross bars 20 to reduce the net load of the cable tray 1 as well as to offer savings in the amount of material used. This feature can also be equivalently applied to the side bars 10 and 11.
  • the cable tray 1 in which the side bars 10 and 11 , and the cross bars 20 are integrally formed, it is possible not only to ensure maximum safety in terms of structural stability but also to achieve a lightweight structure. Accordingly, the cable tray of the invention can be properly used for a wiring operation in which typical cables as well as relatively heavy pipes are distributed on the ceiling or the wall of a plant, a vessel, a marine structure and the like.
  • a reinforcing part 23 is integrally formed in the connecting portions where the side bars 10 and 11 are connected to the cross bars 20 in order to further reinforce the durability of the connecting portions. Due to the reinforcing part 20, even if a number of heavy pipes are placed on the cross bars 20, it is possible to prevent the connecting portions of the cross bars 20 and the side bars 10 and 11 from losing durability, which otherwise would lead to their fracture in severe cases.
  • the reinforcing part 23 can be formed with a triangular configuration of the connecting portions of the cross bars 20 and the side bars 10 and 11. This configuration can prevent any one of the cross bars 20 and the side bars 10 and 11 from losing durability, and especially if the reinforcing part 23 is rounded at the end, can protect workers from being accidentally injured during the process of wiring the cables.
  • a perimetric reinforcing part 24 is formed on and bent downwards from the perimeter of the cross bar 20 in order to prevent the cross bar 20 from sagging down under a load of cables arranged in the cable tray 1. That is, the perimetric reinforcing part 24 can prevent the cross bar 20 from being deformed by sagging.
  • the perimetric reinforcing part 24 as above is bent downwards from the cross bars 20 in the case of the new marine type cable tray 1.
  • FIG. 15 shows another embodiment that has been devised to prevent the cross bars 20 from being deformed by sagging.
  • a central reinforcing part 25 is formed on and bent upwards from the central portion of the cross bar 20 in the case of a new marine type cable tray 1.
  • a central reinforcing part 25 is formed on and bent upwards from the central portion of the cross bar 20.
  • the central reinforcing part 25 can increase the overall endurance of the cross bar 20 in order to protect the cross bar 20 from the risk of sagging as well as the risk of being fractured when a variety of cables and pipes are arranged in the cable tray.
  • the cable tray 1 of the invention may further include a plating layer (not shown) formed on the surface of the side bars 10 and 11 and the cross bars 20. The plating layer is formed by galvanization in order to protect the cable tray 1 from oxidation and to thereby increase the life span of the cable tray 1.
  • This plating layer can be generally formed by hot dip zinc galvanization.
  • a passivation layer (not shown) is also formed on the surface of the cable tray 1 for uniformization.
  • the passivation layer can be formed for example by spraying epoxy-polyester based coating powder on the surface of the cable tray.
  • the spraying is generally carried out by electrostatic powder coating.
  • the coating powder is uniformly sprayed on the entire surface of the cable tray 1 including the side bars 10 and 11 and the cross bars 20, thereby uniformly forming a passivation layer on the surface of the cable tray 1.
  • painting may be performed by spraying Zn- or Mn-based surface conditioner for the purpose of surface uniformization, or liquid phosphate can be sprayed on the cable tray 1 to form a film with a uniform thickness.
  • the plating layer is formed on the surface of the cable tray 1 by galvanization in order to prevent oxidation, and the passivation layer is formed on the plating layer by spraying epoxy-polyester based coating powder or forming a phosphate film in order to make uniform the entire surface of the cable tray 1.

Abstract

Chemin de câbles utilisé lors d’une opération de câblage faisant intervenir des câbles ou des tuyaux relativement lourds distribués dans une installation, un navire, une structure marine et autres. Le chemin de câbles comporte des barres latérales orientées dans une direction de câblage d’un câble et des barres transversale en alternance avec des ouvertures, les barres latérales faisant partie intégrante des barres transversales et étant cintrées dans une direction s’écartant de celles-ci. Comparativement à un chemin de câble préfabriqué classique, les procédés de fabrication sont réduits, ce qui permet d’améliorer l’efficience, les ouvertures permettent de réduire la quantité de matériau utilisée et d’alléger la structure, d’où une durabilité prolongée de l’ensemble. Le chemin de câbles permet donc la distribution aisée de tuyaux relativement lourds.
