- the invention relates to an extruded, cross-sectionally U-shaped channel profile, consisting of a base and legs integrally formed thereon, with a cover part which can be connected to the free ends of the legs.
- Such channel profiles are known in large numbers. They serve as installation ducts for the laying of electrical or pipelines, are used in the wall or ceiling installation of such ducts, serve as parapet ducts and are used in many other areas of application.
- a generic channel profile is known from German utility model 77 02 117.
- elongated holes are formed in the longitudinal direction for the introduction of retaining clips.
- the invention takes advantage of the experience that has been made, for example, in the manufacture of corrugated pipes. There, considerable cross-sectional reductions of the tube walls were achieved by the shaping of ring corrugations, so that ring-corrugated tubes could be produced with considerably less material and with comparable strength to compact tubes.
- the essence of the invention is thus a type of transverse corrugation for producing transverse ribs, at least in the area of the base of the U-shaped channel profile. According to the invention, this transverse corrugation can be produced by embossing, punching, via vacuum link chains or by differences in shear during extrusion.
- the transverse corrugations are introduced into the wall areas with the weakened cross section. It can be advantageous here that the legs, which are thicker in cross-section than the base, protrude slightly into the base with their wall thickness in the deflection area relative to the base, and that the impressions start from the wall thickness of the deflection areas. The strength resulting from these impressions thus runs into the thickened side wall, preferably here in the radius area.
- embossments in cross, T or other form can also be introduced into the wall thickness-weakened base.
- Star shapes, circles, polygons, etc. can be incorporated into the wall, which is weakened by the wall thickness.
- the impressions can be in planar form or can be reinforced in a prism shape at the greatest load level, ie the bending moment.
- circular structures are introduced into the base, which additionally contribute to increasing the stability.
- Such circular structures can be designed with a raised edge, as a result of which, for example, a screw head of a fastening screw can be countersunk in the interior formed. In addition to increasing the strength, this also prevents damage to lines to be drawn into the lumen of the channel profile, for example via the sharp-edged screw head.
- impressions according to the invention can be introduced both into the base and / or into the legs and / or the cover part.
- Cross-corrugations in the cover part can, if they are introduced over a large area, serve in addition to the reinforcement property and also serve as a raised base on the cover for advertising elements such as company names, system names, test marks, etc.
- the impressions according to the invention can be introduced into the relevant wall thickness-reduced wall regions at any intervals.
- the embossments can also be in a mixed form, namely once as transverse corrugations transverse to the longitudinal axis of the channel profile in the base, in the legs and / or in the lid and additionally in round, cross, star, T and polygonal embossments.

- the channel profile 1 consists of the wall thickness-weakened base 11 and the leg 12 shown, to which the leg not shown in the picture on the other side of the channel profile 1 corresponds in mirror image.
- the transversely continuous impression 111 is introduced into the base 11, which is weakened by the wall thickness. This indentation 111 runs in the edge region to the leg 12 into the deflection region 123 to the base 11, so that the indentation 111 starts from the wall thickness of the deflection region 123.
- the circular indentation 112 is introduced into the base 11.
- This circular indentation 112 delimits, with its peripheral edge 1121, a circular projection which corresponds to the height of the indentation 111 and surrounds the screw head 4 of a fastening screw in a protective manner.

The invention provides a material-saving production of conduit profiles while completely adhering to the required stability at the same time. To this end, at least the wall thickness of the base of the U-shaped conduit profile is reduced, and impressions which reinforce are placed in a section by section manner inside said base which has a reduced wall thickness.
Description
Kanalprofil Channel profile
Die Erfindung betrifft ein extrudiertes, im Querschnitt U-förmiges Kanalprofil, bestehend aus einer Basis und daran einstückig angeformten Schenkeln, mit einem mit den freien Enden der Schenkel verbindbaren Deckelteil.The invention relates to an extruded, cross-sectionally U-shaped channel profile, consisting of a base and legs integrally formed thereon, with a cover part which can be connected to the free ends of the legs.
Derartige Kanalprofile sind in großer Anzahl bekannt. Sie dienen als Installationskanäle zur Verlegung von Elektro- oder Rohrleitungen, werden bei der Wand- oder Deckeninstallation solcher Leitungen benutzt, dienen als Brüstungskanäle und werden in vielen anderen Anwendungsbereichen eingesetzt.Such channel profiles are known in large numbers. They serve as installation ducts for the laying of electrical or pipelines, are used in the wall or ceiling installation of such ducts, serve as parapet ducts and are used in many other areas of application.
Ein gattungsbildendes Kanalprofil ist aus dem Deutschen Gebrauchsmuster 77 02 117 bekannt. Dort ist ein Installationskanal mit einem U-förmigen, durch einen Deckel verschließbaren Gehäuse zur Aufnahme von Drähten, Kabeln, Leitungen, Schläuchen und dergleichen beschrieben. In den freien Endbereichen der Seitenwandungen dieses Installationskanals sind in Längsrichtung verlaufende Langlöcher zum Einbringen von Halteklammern ausgebildet.A generic channel profile is known from German utility model 77 02 117. There is an installation channel with a U-shaped, closable by a cover housing for receiving wires, cables, lines, hoses and the like is described. In the free end regions of the side walls of this installation channel, elongated holes are formed in the longitudinal direction for the introduction of retaining clips.
Gegenüber solchen Kanaiprofilen geht das Bestreben der Hersteller und der Verbraucher heute dahin, die Wanddicke der Profile möglichst niedrig zu halten. Diesem Bestreben sind jedoch wegen der geforderten Stabilität bei Herstellung und Installation relativ enge Grenzen gesetzt.Compared to such Kanai profiles, the efforts of manufacturers and consumers today are to keep the wall thickness of the profiles as low as possible. However, due to the stability required during manufacture and installation, this endeavor is subject to relatively narrow limits.
Aus diesem Grunde wird in der DE 82 31 934 U1 vorgeschlagen, den Boden und/oder die Seitenwände und/oder den Deckel des Kanalprofils wenigstens teilweise als Hohlkammerprofil auszubilden. Dieser Vorschlag geht davon aus, daß Hohlkammerprofile in der Regel eine hohe Stabilität bei geringem Gewicht aufweisen, daß also auf diese Weise die gewünschte Materialeinsparung herbeigeführt werden kann. Allerdings wird dabei übersehen, daß derartige Hohlkammerprofile zwei durchlaufende Wandungen mit zwischengeschalteten Stegen als Abstandhalter aufweisen, daß also die Materialeinsparung - wenn überhaupt eine solche zu erzielen ist - relativ gering ausfallen wird.
Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, eine materialeinsparende Herstellung solcher Kanalprofile bei gleichzeitiger voller Aufrechterhaltung der erforderlichen Stabilität anzugeben. Erfindungsgemäß wird dazu vorgeschlagen, daß wenigstens die Basis des U-förmigen Kanalprofils in ihrer Wanddicke reduziert ist und daß in diese wanddickenreduzierte Basis abschnittsweise der Verstärkung dienende Einprägungen eingebracht sind.For this reason, it is proposed in DE 82 31 934 U1 to at least partially design the bottom and / or the side walls and / or the cover of the channel profile as a hollow chamber profile. This proposal is based on the fact that hollow chamber profiles generally have a high stability with low weight, so that the desired material savings can be achieved in this way. However, it is overlooked that hollow chamber profiles of this type have two continuous walls with interposed webs as spacers, so that the material savings - if any can be achieved at all - will be relatively small. This is where the invention comes in, which has set itself the task of specifying a material-saving production of such channel profiles while at the same time fully maintaining the required stability. According to the invention it is proposed that at least the base of the U-shaped channel profile is reduced in its wall thickness and that portions of the reinforcement serving for reinforcement are introduced in sections in this reduced-wall base.
Die Erfindung macht sich die Erfahrungen zunutze, die beispielsweise bei der Herstellung von Wellrohren umfangreich gemacht worden sind. Dort wurden erhebliche Querschnittsreduzierungen der Rohrwände durch die Anformung von Ringwellungen erzielt, so daß ringgewellte Rohre mit erheblich geringerem Materialaufwand bei vergleichbarer Festigkeit zu kompakten Rohren hergestellt werden konnten. Kern der Erfindung ist damit eine Art Querwellung zur Erzeugung von querverlaufenden Rippen, wenigstens im Bereich der Basis des U-förmigen Kanalprofils. Diese Querwellung kann erfindungsgemäß durch Prägen, Stanzen, über Vakuumgliederketten oder durch Schubunterschiede bei der Extrusion hergestellt werden.The invention takes advantage of the experience that has been made, for example, in the manufacture of corrugated pipes. There, considerable cross-sectional reductions of the tube walls were achieved by the shaping of ring corrugations, so that ring-corrugated tubes could be produced with considerably less material and with comparable strength to compact tubes. The essence of the invention is thus a type of transverse corrugation for producing transverse ribs, at least in the area of the base of the U-shaped channel profile. According to the invention, this transverse corrugation can be produced by embossing, punching, via vacuum link chains or by differences in shear during extrusion.
Wesentlich ist für ihre Wirkungsweise, daß die Querwellungen in die Wandungsbereiche mit dem verschwächten Querschnitt eingebracht sind. Hierbei kann es von Vorteil sein, daß die gegenüber der Basis im Querschnitt dickeren Schenkel mit ihrer Wanddicke im Umlenkbereich zur Basis geringförmig in die Basis hineinragen und daß die Einprägungen von der Wanddicke der Umlenkbereiche ausgehen. Damit läuft die Festigkeit, die von diesen Einprägungen ausgeht, bis in die verdickte Seitenwand, bevorzugt hier in den Radienbereich ein.It is essential for their mode of operation that the transverse corrugations are introduced into the wall areas with the weakened cross section. It can be advantageous here that the legs, which are thicker in cross-section than the base, protrude slightly into the base with their wall thickness in the deflection area relative to the base, and that the impressions start from the wall thickness of the deflection areas. The strength resulting from these impressions thus runs into the thickened side wall, preferably here in the radius area.
Neben der Wellenform oder an deren Stelle können in die wanddickenverschwächte Basis auch Einprägungen in Kreuz-, T- oder sonstiger Form eingebracht sein. So können Sternenformen, Kreise, Vielecke usw. in die wanddickenverschwächte Wandung eingebracht sein. Hierbei können die Einprägungen in planer Form vorliegen oder an der größten Belastungsebene, d. h. dem Biegemoment, prismenförmig verstärkt sein.
Es hat sich als besonders vorteilhaft herausgestellt, wenn neben den wellenförmigen Einprägungen kreisförmige Gebilde in die Basis eingebracht sind, die zusätzlich zur Stabilitätserhöhung beitragen. Solche kreisförmigen Gebilde können mit erhöhtem Rand ausgebildet sein, wodurch beispielsweise in dem gebildeten Innenraum ein Schraubenkopf einer Befestigungsschraube versenkt werden kann. Dadurch wird zusätzlich zur Festigkeitserhöhung eine Beschädigung von in das Lumen des Kanalprofils einzuziehenden Leitungen über beispielsweise den scharfkantigen Schraubenkopf verhindert.In addition to the waveform or in its place, embossments in cross, T or other form can also be introduced into the wall thickness-weakened base. Star shapes, circles, polygons, etc. can be incorporated into the wall, which is weakened by the wall thickness. In this case, the impressions can be in planar form or can be reinforced in a prism shape at the greatest load level, ie the bending moment. It has proven to be particularly advantageous if, in addition to the wave-shaped impressions, circular structures are introduced into the base, which additionally contribute to increasing the stability. Such circular structures can be designed with a raised edge, as a result of which, for example, a screw head of a fastening screw can be countersunk in the interior formed. In addition to increasing the strength, this also prevents damage to lines to be drawn into the lumen of the channel profile, for example via the sharp-edged screw head.
Die erfindungsgemäßen Einprägungen können sowohl in die Basis, und/oder in die Schenkel und/oder das Deckelteil eingebracht sein. Querwellungen im Deckelteil können dabei, sofern sie flächig eingebracht sind, neben der Verstärkungseigenschaft noch zusätzlich als erhaben auf dem Deckel angeordnete Basis für Werbeelemente wie beispielsweise Firmennamen, Systembezeichnung, Prüfzeichen usw. dienen.The impressions according to the invention can be introduced both into the base and / or into the legs and / or the cover part. Cross-corrugations in the cover part can, if they are introduced over a large area, serve in addition to the reinforcement property and also serve as a raised base on the cover for advertising elements such as company names, system names, test marks, etc.
Die erfindungsgemäßen Einprägungen können in beliebigen Abständen in die betreffenden wanddickenreduzierten Wandbereiche eingebracht sein. Die Einprägungen können auch in Mischform vorhanden sein, nämlich einmal als Querwellungen quer zur Längsachse des Kanalprofils in der Basis, in den Schenkeln und/oder im Deckel und zusätzlich in runden, Kreuz-, Stern-, T- und mehreckigen Einprägungen.The impressions according to the invention can be introduced into the relevant wall thickness-reduced wall regions at any intervals. The embossments can also be in a mixed form, namely once as transverse corrugations transverse to the longitudinal axis of the channel profile in the base, in the legs and / or in the lid and additionally in round, cross, star, T and polygonal embossments.
In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Kanalprofils schematisch dargestellt; es zeigt:In the drawing, an embodiment of the channel profile according to the invention is shown schematically; it shows:

Figur 1 zeigt den Querschnitt durch ein Kanalprofil 1 mit Deckelteil 3 im Schnitt entlang der Mittellinie A-A. Das Kanalprofil 1 besteht aus der wanddickenverschwächten Basis 11 und dem gezeigten Schenkel 12, dem der im Bild nicht gezeigte Schenkel auf der anderen Seite des Kanalprofils 1 spiegelbildlich entspricht.
In die wanddickenverschwächte Basis 11 ist die quer durchgehende Einprägung 111 eingebracht. Diese Einprägung 111 verläuft im Randbereich zum Schenkel 12 in den Umlenkbereich 123 zur Basis 11, so daß die Einprägung 111 von der Wanddicke des Umlenkbereichs 123 ausgeht.Figure 1 shows the cross section through a channel profile 1 with cover part 3 in section along the center line AA. The channel profile 1 consists of the wall thickness-weakened base 11 and the leg 12 shown, to which the leg not shown in the picture on the other side of the channel profile 1 corresponds in mirror image. The transversely continuous impression 111 is introduced into the base 11, which is weakened by the wall thickness. This indentation 111 runs in the edge region to the leg 12 into the deflection region 123 to the base 11, so that the indentation 111 starts from the wall thickness of the deflection region 123.
Neben der Ausprägung 111 ist die kreisförmige Einprägung 112 in die Basis 11 eingebracht. Diese kreisförmige Einprägung 112 begrenzt mit ihrem umlaufenden Rand 1121 eine kreisförmige Aufwerfung, die in der Höhe der Einprägung 111 entspricht und den Schraubenkopf 4 einer Befestigungsschraube schützend umgibt.In addition to the indentation 111, the circular indentation 112 is introduced into the base 11. This circular indentation 112 delimits, with its peripheral edge 1121, a circular projection which corresponds to the height of the indentation 111 and surrounds the screw head 4 of a fastening screw in a protective manner.
Figur 2 zeigt dies perspektivische Ansicht des Deckelteils 3 mit den abschnittsweise eingebrachten Quereinprägungen 32, 33. Diese Einprägungen 32, 33 sind entsprechend der Schilderung zur Basis 11 mit der Einprägung 111 in den Randbereichen am Übergang zwischen dem dickeren Halteschenkel 31 und der wanddickenverschwächten Basis 34 des Deckels 3 so eingebracht, daß die Einprägungen 32, 33 erhaben nach außen abstehen. Sie dienen in dieser Form als Grundlage für einen Werbeaufdruck.FIG. 2 shows this perspective view of the cover part 3 with the transverse embossments 32, 33 introduced in sections. These embossments 32, 33 are, according to the description of the base 11 with the embossment 111 in the edge regions at the transition between the thicker holding leg 31 and the base 34, which is weakened by the wall thickness Cover 3 introduced so that the impressions 32, 33 protrude outwardly. In this form, they serve as the basis for an advertising imprint.
Die Einprägungen 32, 33 aus Figur 2 können auch zum Lumen 13 des Kanalprofils 1 durchgedrückt sein, so daß sich auf der Oberseite der Basis 34 des Deckels 3 entsprechende Quervertiefungen ergeben. Selbstverständlich können die zur Basis 11 geschilderten Einprägungen der anderen Formgestaltung ebenfalls auch in die Basis 34 des Deckeiteils 3 zusätzlich zu den Quereinprägungen oder allein eingebracht sein.
The embossments 32, 33 from FIG. 2 can also be pushed through to the lumen 13 of the channel profile 1, so that corresponding transverse depressions result on the upper side of the base 34 of the cover 3. Of course, the impressions of the other design described for the base 11 can also be introduced into the base 34 of the cover part 3 in addition to the transverse impressions or alone.
