The channel's profile
(57) Abstract:The invention relates to the mounting equipment for laying of cables and pipelines and ensures efficiency of manufacturing channels. Profile channel has a cross section of U-shaped and provided with a part in the role of a cover connected with the free ends of the arms of the U-shaped profile. These free shoulders of the U-shaped profile formed solid shelves for a fixed fastening of the overlapping elements arranged at a certain distance from each other. In the proposed profile of the channel at least the base of the channel is weakened in thickness. In this weakened the thickness of the base in some areas made extruded sections for extra rigidity. Such sites can have different shapes and be located not only on the basis, but also on the shoulders of the U-shaped profile and the cover profile of the channel. 4 C.p. f-crystals, 2 Il. The invention relates to extruded profile channel has a cross-sectional U-shape with the upper part forming the cover and connected with the free ends of the arms of the U-shaped profile, with the free ends of the arms of the U-shaped profile formed United at a certain distance.There are a large number of such profiles of the channels. They serve as mounting channels for wiring and pipes that are used for laying of such conductors in walls and ceilings serve as a parapet channels and are used in various fields.This profile of the channel is known from German utility model 7702117. There is described a mounting channel with a U-shaped body, closed by a cover, for wiring, cables, wires, hoses, etc. In the free end areas of the side walls of this mounting channel made passing in the longitudinal direction of the elongated holes to install the retaining brackets.The desire of the manufacturer and consumer of such profiles is the execution profile wall thin as possible. However, these aspirations are limited to a relatively narrow confines of the stability required for fabrication and erection.Therefore, in DE 8231934 U1 offered to do the bottom and/or side walls and/or the cover profile of the channel at least partially in the form of a hollow profile. This proposal comes from the fact that profiles with a cavity, as a rule, high stability with low weight that postout two solid walls with intermediate partitions in the form of the spacer elements, resulting in savings of material, if it can be achieved, will be relatively low.Here can be applied to this invention, which is an economical manufacture of such profiles while simultaneously preserving the necessary stability.For this extruded profile channel has a cross-sectional U-shape, with the part forming the cover connected with the free ends of the arms of the U-shaped profile, and to free the shoulders of the U-shaped profile formed directed to the cavity channel solid shelves for a fixed fastening of the overlapping elements arranged at a certain distance, according to the invention, it is proposed to weaken the wall thickness of at least the base of the U-shaped profile and run at the same time, weakened the thickness of the base, on separate sites produced by squeezing the tabs that increase rigidity.When creating inventions used the experience gained, for example, in the manufacture of corrugated pipes. There was achieved a significant reduction of pipe wall thickness in cross-section by forming annular corrugations, making udalosti strength compared to compact handsets. Therefore, the invention is a kind of cross shirring for the formation of ribs, passing transversely at least in the area of the base of the U-shaped profile of the channel. This transverse corrugation can be made by stamping, punching, through the circuits of vacuum sections or by differences in shear during extrusion.Thus it is essential that the transverse corrugations in the walls are weakened cross-section. Moreover, it may be preferable to cross-sectional shoulders U-shaped profile were thicker base, the thickness of the transition zone was slightly above the base, and to extruded sections started from the walls in zones of transition. Due to this increase in the rigidity created by these extruded sections, is provided until thickened side wall, here, preferably, in the radius area.Along with a corrugated shape, or instead of weakened by the thickness of the base can be extruded cross sections, T-shaped or other shapes. So, on the wall, weakened by the thickness, can be shaped as stars, circles, polygons, etc., and the extruded sections can be square is occurring.It was found that particularly preferred is the execution, which in the base along with squeezing out the areas having the form of corrugations, are having the shape of a circle education, improving stability. Such education, having the form of a circle, can be performed with a protruding edge, so that, for example, in the formed cavity may be recessed head screws. Due to this, in addition to increasing the stiffness prevents damage extending through the internal cavity of the profile channel conductors, for example, the screw head having sharp edges.Extruded sections according to the invention can be performed as in the basis, so, if necessary, on the shoulders of the U-shaped profile and/or cover. When this transverse corrugation in the lid, if it is flat, can, in addition to performing the functions of strength, additionally serve because they are on the cover, the base elements of advertising, for example, names of firms, notation systems, sign checks, etc.Extruded sections according to the invention can be performed on the respective weakened by the thickness of the zones of the wall, with all the pepper of corrugations, passing transversely to the longitudinal axis of the profile of the channel, based on the shoulders of the U-shaped profile and/or on the cover, and, optionally, in the form of a circular, cross-shaped, star-shaped, T-shaped or polygonal extruded sections.The figure schematically shows an example of the execution profile of the channel according to the invention.In Fig. 1 shows a cross-section profile of the channel with the holding bracket and cover;
Fig. 2 is a perspective image of the cover.In Fig. 1 shows a cross-section of profile 1 channel with the holding bracket 2 and the cover 3 in section along the middle line A-A. the profile of the 1 channel is weakened by the thickness of the base 11 and is shown on the drawing shoulder 12 of the U-shaped profile, which in mirror image corresponds to the shoulder of the U-shaped profile on the other side of the profile 1 channel, not shown in the drawing. The shoulder 12 of the U-shaped profile has at its free end a lug 121 included in the cavity 13 of the profile of the 1 channel and provided with a hole 1211, through which the retaining element 21 of the bracket 2. The cover 3 is attached to its rounded edge 31 on the protruding inward portion 122 of the shoulder 12 of the U-shaped profile.In this weakened the thickness of the base 11 you what Chu 12 U-shaped profile in an area of 123 transition to the base 11 so that extruded section 111 starts from the wall zone 123 of the transition.Along with the extruded section 111 of the base 11 perform circular extruded section 112. This circular extruded section 112 its borders along the perimeter edge 1121 with a circular protrusion corresponding to the height of the extruded section 111, and encircles the cylinder 4 mounting screws, protecting her.In Fig. 2 shows in perspective the cover 3 with separate transverse extruded sections 32, 33. These extruded to the base 11 sections 32, 33, in accordance with the image, together with the extruded sections 111 are placed in edge zones at the transition between the thicker retaining shoulder 31 and weakened by the wall thickness of the base 34 of the cover 3 so that the extruded sections 32, 33 are convex outward. In this form, they serve as the basis for print advertising.Extruded sections 32, 33 according to Fig. 2 can go into the cavity 13 of the profile 1 channel so that the upper side of the base 34 of the cover 3 are obtained the corresponding transverse recess. Needless to say, converted to the base 11 of the extruded sections with another form of execution can also be placed in audirovannyj profile of the channel, having in cross section U-shaped, with the part forming the cover connected with the free ends of the arms of the U-shaped profile, and to free the shoulders of the U-shaped profile formed directed to the cavity channel solid shelves for a fixed fastening of the overlapping elements arranged at a certain distance, wherein at least the base (11) of the U-shaped profile (1) channel weakened by the thickness of its walls, and that weakened the thickness of the base (11) in some areas made extruded sections (111, 112), employees for extra rigidity.2.
