Description

Support profile for cable trays.

Field of the Invention

The present invention relates to a profile of support for cable trays, preferably used by employees in electrical installations to support these elements.

Background of the invention

The supports for cable trays are a very important component in electrical installations such as supporting elements The so-called omega brackets (so called by the shape of its cross section) they are a support medium for cable trays usually used in these installations for fixing to the ceiling or walls.

Omega profiles are usually in the form of straight, L-shaped or C-shaped sections, and are fixed to the floor, wall or ceiling using through screws of holes made in the support itself.

To avoid deformation of the profile itself support omega as a result of the pressure exerted by the fixing screws to the floor, wall or ceiling are used usually metal or plastic stops constituted as prismatic pieces, usually of trapezoidal section. These bumpers they are placed in the gap between the omega support and the corresponding surface, and are supplied as parts independent. The Spanish utility models 1045098 and 1057771 of the applicant himself describe and claim several examples of these stops for omega supports.

The traditional omega brackets, which they need said studs to avoid deformation in the assembly, have a characteristic profile, with divergent side walls towards below that at the bottom bend, opening up, similar to the Greek letter that gives them their name.

These supports fulfill their function in a manner adequate and avoiding deformations; however, it is necessary carry out a pre-assembly or an assembly on site with the cue described above, with the consequent additional cost that they involve the use of one more piece and the time necessary for its mounting on the omega bracket, making it desirable to arrange a device that avoids the use of an additional piece without this must give up adequate resistance to deformations

Summary of the invention

Thus, the object of the present invention is provide a support profile for cable trays that avoid using additional parts during assembly or pre-assembly

The invention provides a support profile for cable trays, comprising a section consisting of two divergent side walls down that in its part lower fold out, and on top they are joined by a raised central wall, having the wall raised central holes made on it, in which the side walls comprise a rectilinear upper section divergent down, a central section of profile curved-convex, outgoing, and a stretch lower vertical short, below and after the section curved-convex

Through this configuration of the walls side of the profile an additional resistance is achieved in said profile that implies an increase in load capacity without Need to add additional parts.

Another advantage of the invention is that with it achieves a reduction in the time required to assemble the Profile to the desired surface.

Another advantage of the invention is that it can apply to universal profiles, of which they can support both cable trays of grid as of sheet metal.

Other features and advantages of this invention will follow from the detailed description that follows from an illustrative embodiment of its object in relation to Accompanying figures.

Brief description of the drawings

It will be illustrated below limiting the object of the present invention, making reference to the accompanying drawings, in which:

Detailed description of the invention

Figure 1 shows an exploded view of the set consisting of an omega support profile for trays Cable carrier of the prior art and other elements necessary for fixing to a surface, in this case, a vertical wall These elements are a threaded bolt, a washer, a block and a stop that is placed in the gap between the Omega support and corresponding surface.

As seen in said figure 1, the support Omega represented has a characteristic profile, with walls straight sides divergent downwards than in their part lower fold, opening up.

Figure 2 shows a front view of a support profile 1 for cable trays according to this invention. Like traditional omega support, this profile 1 it comprises a section 2 constituted by two side walls 5 divergent down that at the bottom bend outside, and at the top they are joined by a wall 6 central raised, the central wall 6 having raised some equidistant parallel transverse openings 7 practiced on she and that continue partially by the side walls 5. Without However, unlike the commonly used omega support, the side walls 5 of the support profile 1 of the invention they comprise a divergent rectilinear upper section 8 downwards, a central section 9 with a curved-convex profile, outgoing out, and a short 10 vertical short section, below and to continuation of section 9 curved-convex, as observes in the front view of the realization of said profile 1 of support shown in figure 2.

Figures 3 and 4 show an embodiment of the support profile 1 of the invention in which there is a section 3 additional of said profile 1 which is perpendicular to the section 2 located horizontally; this embodiment is especially suitable for wall fixing. In said embodiment it is also observed that the support profile 1 is universal, that is, it serves to support both grid trays 11 (figure 3) and sheet trays 12 (figure 4). In said support profile 1, in addition to the central wall 6 high additionally comprises about 7 parallel crossbars equidistant practiced on it and that continue partially 5 side walls.

In the support profile 1 represented in the Figure 3 section 9 curved-convex of each wall 5 side may have an elevation that allows the support of the horizontal rods 13 of grid cable trays, one  once said horizontal rods 13 are inserted through the openings 7 cross sections in the raised central wall 6 and which continue partially through the side walls 5.

In the assembly of figure 4, the tray sheet 12 is placed on the support so that the holes of both and can be joined together by means of union not shown (for example, bolts and nuts).

Figure 5 represents a perspective view of another support profile 1 for cable trays according to the present invention, which further comprises another section 4 perpendicular to section 3 and parallel to section 2 comprising transverse openings 7, and of the same profile as them. Profile 1 represented in this figure 5 is specially designed for ceiling mount.

Figure 6 represents a support profile 1 for single section 2 cable trays according to this invention with a grid tray 11 mounted on it, for ceiling fixing. We observe that the holes located in the Profile 1 ends are crossed by two threaded rods 14 that are fixed at its upper end to the ceiling.

The same support of figure 6 is represented in Figure 7, although in this case applying for fixing to floor 15. The side view of the assembled assembly of figure 7 represents a support profile 1, a grid tray 11 located on said support profile 1 and a ground connection means 15 (in this case, a bolt 16) that passes through one of the holes practiced on the upper central wall 6 of the profile 1 of support.

In the embodiments shown in Figures 3, 5 and 6 the raised central wall 6 of the profiles 1 has about equidistant parallel transverse openings 7 practiced on they and that continue partially by the side walls 5, in which are inserted the corresponding horizontal rods 13 of the grid cable trays 11 located on said profiles 1.

In the previous embodiments it is observed in addition that the lower lateral ends can be found folded up divergently, delimiting a species of concave lateral channels.

In the preferred embodiments of the invention we have just described can introduce those modifications within the scope defined by the following claims.
