Abstract

Cable Tray Umbrellas on the pipe bridge, is intended for nrůmyelová factories, especially chemical industries. Stand, as part of the gear? is divided into individual bars, flange joints. Stojino, it is anchored to the cross-member of the pipe bridge. is attached to the bottom web member bracket for bridge and rail and the upper rod joins the 3'echa. Stojina is for outdoor use a applies mass production requirements and gradual increases in equipment capacity for saved? cables.

Description

The invention relates to a web for cable routes located on a pipe bridge in an industrial plant.

Pipe bridges are used, among other constructions, for the cable routing of cable routes. The common routing of pipes and cables is governed by the relevant safety regulations and this method is expedient, as it does not save space in the industrial distribution. Cable routes are placed on pipeline bridges newly built but straight? bridges that have been used for a long time. The number of stored cables along the length of the route is not the same and in case of changes in production or its extension, demands are made to increase the storage space for other cables. Cable routing equipment consisting of webs, booms and cable grates must also meet these requirements.

The prior art solutions use either common types of equipment, which are also intended for other electrical distribution systems and which are not suitable for outdoor purposes, or are used assemblies manufactured directly on a pipe bridge, mainly by welding. The additional expansion of the cable route leads to an increase in the number of cable gratings in certain sections of the bridge, and thus necessitates the elongation of the webs, which is difficult with respect to adjacent pipelines.

The above-mentioned drawbacks are eliminated by a web for cable ducts located on a pipe bridge, which consists in that the web is detachably composed of vertical bars provided with brackets for cable gratings that are terminated, except for the lower end of the vertical bar which is anchoring webs with horizontal flange plates provided with holes. The individual bars of the web are then connected to each other by means of screws, nuts and washers. The roof plate is connected to the flange plate with holes at the highest vertical bar. For cable operation, it is possible to unload the console for the walkway with railings from the lowest vertical bar.

With this new solution, only the necessary equipment according to the required number of laid cables is installed in each section of the pipe bridge. If the cable route is enlarged, the roof is removed and another rod is added to the web

AND

-2ne brackets for cable grates and roof and re-attach to the web. The individual parts of the web can be pre-made and connected to the bridge without welding by screw connections, the web parts meet the requirements for mass production.

The accompanying drawings show a solution for cable ducts placed on a duct bridge according to the invention, wherein FIG. 1 shows a vertical cross-section of a two-story duct bridge with a web placed; FIG. 2 is a magnified detedL A of FIG. Fig. 3 shows a horizontal section taken along line BB in Fig. 2 showing the connection of the brackets for the cable grate to the web; Fig. 4 shows an example of another web design; and Fig. 5 shows the arrangement of two webs with a common operator. footbridge.

The web 1, of the rolled section, is detachably assembled of vertical bars 11, 12, 13 provided with brackets 2. of angles for cable gratings i The individual bars 11, 12, 11 are terminated, except the lower end of the vertical bar 11 which is anchoring £ webs first, fifth horizontal flange plates ² plates in which holes 6 are drilled to interconnect the vertical members 2 using bolts 11 December 13 »nuts 8 and washers and washers on the flange plate 2 ^with holes £ highest vertical rod 13 is connected roof 10 _A From the lowest vertical bar 11, a bracket 15 of steel angles for a service footbridge 16, covered by floor gratings with railing 17, is unloaded. In another exemplary embodiment, the web 1 consists of vertical bars II, 12, 13, 14 and does not have a footbridge. The vertical bars 11, 12 have welded beams on both sides. In another exemplary embodiment, there is shown an arrangement of two kits in which the rows of webs 1 are parallel, longitudinal beams 20 are attached to the brackets 15 to receive floor gratings, which are detachably connected.

After removing the floor grates, the pipe mounting pieces can be inserted and placed on the crossbar 19.

The web for cable ducts located on a pipe bridge is also suitable for use on building structures and on low-lying overhead cable ducts. Further its use is in transition structures of cable ducts to cable bridges ·
