Abstract
Description
Die vorliegende Erfindung betrifft zunächst eine Kanaldiele, vorzugsweise für eine Kammerplatten-Verbaueinheit, wobei der Querschnitt der Kanaldiele in einer quer zu ihrer Dielenlängsrichtung orientierten Querschnittsebene mehrere Querschnittssegmente, die in der Querschnittsebene in verschiedene Richtungen orientiert sind, umfasst.The present invention initially relates to a channel dowel, preferably for a chamber-plate shoring unit, wherein the cross-section of the channel dikes in a cross-sectional plane oriented transversely to its plank longitudinal direction comprises a plurality of cross-sectional segments which are oriented in different directions in the cross-sectional plane.
Bekannt sind stählerne Kanaldielen für die Verwendung beim sog. Stahl-Kammerplatten-Verbau. Diese Technik findet Einsatz beim Grabenbau (bspw. bei Rohrverlegearbeiten) in nicht kurzfristig standfesten Böden. Dabei erfolgt zunächst ein Voraushub von nur begrenzter Tiefe, in den mit Kanalstreben gegeneinander abgestützte stählerne Kammerplatten eingestellt werden. In die oben und unten offenen Kammern der Kammerplatten werden anschließend von oben Kanaldielen eingeführt und im Wechsel mit dem weiteren tieferen Grabenaushub aufgrund ihrer schweren Handhabbarkeit mit einem Baggerlöffel auf Tiefe gedrückt. Je nach Erstreckung der Kanaldielen in ihrer Dielenlängsrichtung können so auch tiefere Gräben an ihren seitlichen Wänden abgestützt bzw. verbaut werden, wobei sich im oberen Grabenausschnitt die Kanaldielen gegen die auch eine Führung bildenden Kammerplatten abstützen und je nach Tiefe des Grabens unterhalb der Kammerplatten die Kanaldielen bspw. durch ein Erdwiderlager oder auf andere Weise abgestützt sein können. Nach dem bspw. Verlegen von Rohren wird der Graben wieder verfüllt und die aus Stahl hergestellten und daher schweren Kanaldielen mittels eines Baggers, Kranes oder dergleichen aus den Kammerplatten nach oben heraus gezogen, worauf auch die Kammerplatten aus dem restlichen Graben entnommen und die Restverfüllung vorgenommen wird. Diese bekannte Anwendung wird als Stahl-Kammerplatten-Grabenverbau bezeichnet. Gegenüber der aus
Vor diesem Hintergrund liegt der Erfindung zunächst die Aufgabe zugrunde, eine Kanaldiele der eingangs genannten Art vorteilhaft weiterzubilden, so dass insbesondere die beschriebenen Nachteile vermieden werden können.Against this background, the object of the invention is first of all to further develop a channel dowel of the type mentioned initially, so that in particular the described disadvantages can be avoided.
Die Aufgabe wird gemäß der Erfindung zunächst und im Wesentlichen in Verbindung mit den Merkmalen gelöst, dass die Kanaldiele überwiegend oder vollständig aus Aluminium und/ oder Aluminiumlegierung hergestellt ist und dass zumindest ein Querschnittssegment zumindest eine hinterschnittene, vorzugsweise T-profilartig hinterschnittene, Nut aufweist, die sich parallel zu der Dielenlängsrichtung der Kanaldiele und vorzugsweise durchgehend entlang der gesamten Länge der Kanaldiele erstreckt. Die Kombination dieser Merkmale ermöglicht es vorteilhaft, dass die erfindungsgemäßen Kanaldielen, die aufgrund ihrer vielseitigen Verwendungsmöglichkeit auch einfach als Dielen (oder auch als Alu-Dielen) zu bezeichnen sind, auch ohne Bagger bzw. vergleichbare Hebemittel verwendbar sind. Einerseits wird im Vergleich zu herkömmlichen Stahl-Kanaldielen durch die erfindungsgemäße Verwendung von Leichtmetall ein signifikant niedrigeres Gewicht erreicht. So kann eine erfindungsgemäße Kanaldiele, die bspw. (d.h. nicht notwendig) in Dielenlängsrichtung eine Länge von 2,5 m und in ihrem dazu senkrechten Querschnitt in Querschnittslängsrichtung 215 mm und in Querschnittsquerrichtung 50 mm misst, ein Gewicht von nur etwa 14 kg aufweisen, das selbst nach den sehr strengen Arbeitsschutz-Vorschriften bspw. in Schweden noch dauernd von einem Arbeiter bewegt werden darf. Im Hinblick darauf muss das Einzelgewicht unter 16 kg liegen. Eine solche Alu-Diele kann bei einer von der Erfindung bevorzugten Verwendung für einen Alu-Kammerplatten-Leichtverbau von Hand in die Kammerplatten eingestellt und nachgedrückt werden und ermöglicht es bspw., Baugruben bis 2 m Tiefe je nach Boden ohne zusätzliche Gurtungen zu verbauen. In Kombination mit dem geringen Gewicht wird die bevorzugte manuelle Handhabung der erfindungsgemäßen Kanaldielen durch deren hinterschnittene, in Längsrichtung verlaufende Nut (vorzugsweise T-Nut) begünstigt, die eine Multifunktionsleiste bildet. Sie kann z.B. mittels einer Steckschraube zum Anklemmen eines Anschlagmittels oder eines Handgriffes zum Eindrücken und Ziehen der Alu-Diele von Hand dienen. Auch kann mittels der T-Nut bspw. ein Stopper an die Kanaldiele angeklemmt werden. Der Stopper kann hinsichtlich seiner Abmessungen so groß dimensioniert sein, dass er über den Rand der in einer Kammerplatte gebildeten Kammer hinaussteht und sich daher nicht mit in die Kammer einschieben lässt. Auf diese Weise kann die erfindungsgemäße Diele beim Einstecken in die Kammer positioniert und in der Kammerplatte, vorzugsweise in einer nachfolgend beschriebenen erfindungsgemäßen Kammerplatte, am weiteren Durchrutschen gehindert werden. Auch kann die erfindungsgemäße Nut als Klemmleiste genutzt werden, um die einzelnen Alu-Dielen mit einer zusätzlichen Gurtung abzustützen, was gegenüber bekannten stählernen Kanaldielen, die nur ein Loch zum Anschlagen besitzen, eine größere Vielseitigkeit ermöglicht. Um die erfindungsgemäße Kanaldiele möglichst langlebig auszuführen, sollte sie aus hochfestem Aluminium bzw. Aluminiumlegierung hergestellt sein, vorzugsweise aus AlZn 4,5 Mg 1 nach DIN 1725 mit einer Streckgrenze über 290 N/mm2 und einer Bruchfestigkeit über 350 N/mm2. Die erfindungsgemäße Kanaldiele ist vorzugsweise aus hochfestem Aluminium/Aluminiumlegierung mit der Festigkeit von Stahl bzw. aus bruchfester Aluminiumlegierung für eine hohe Langlebigkeit hergestellt. Zufolge dieser erfindungsgemäß mittels der Multifunktions-Nut bedarfsgerecht an der Kanaldiele zu befestigenden / zu lösenden Hilfsmittel für den manuellen Einsatz kann der Verbau mittels Körperkraft erfolgen und auf diese Weise nicht nur auf aufwendiges Hebezeug (bspw. auf einen Bagger mit Bohlenzange), sondern je nach Anwendung auch auf weitere Hilfsmittel wie bspw. hydraulische Rütteleinrichtungen verzichtet werden.The object is achieved according to the invention first and essentially in conjunction with the features that the channel dumbbells is predominantly or completely made of aluminum and / or aluminum alloy and that at least one cross-sectional segment has at least one undercut, preferably T-profile undercut groove, the extends parallel to the plank lengthwise direction of the channel planks, and preferably continuously along the entire length of the channel planks. The combination of these features makes it advantageous that the channel boards according to the invention, due to their versatility also simply as planks (or as aluminum planks) are to be called, even without excavator or comparable lifting means are used. On the one hand, a significantly lower weight is achieved compared to conventional steel channel boards by the use of light metal according to the invention. Thus, a channel dowel according to the invention which, for example (ie not necessary) in the plank longitudinal direction has a length of 2.5 m and in its perpendicular cross-section in the longitudinal direction 215 mm and cross-sectional
Wie schon angesprochen, weist der Querschnitt der Kanaldiele in der quer zu ihrer Dielenlängsrichtung orientierten Querschnittsebene mehrere in dieser Querschnittsebene in verschiedene Richtungen orientierte Querschnittssegmente auf. Bei diesen handelt es sich vorzugsweise um im Vergleich zu den Querschnittsabmessungen in Querschnittslängs- und Breitenrichtung vergleichsweise dünnwandige Querschnittssegmente. Einzelne oder mehrere dieser Segmente können innerhalb der Querschnittsebene einen nahezu beliebigen, bspw. in sich geraden oder gebogenen, bspw. auch gerundeten, Verlauf besitzen. Dabei bilden die miteinander einstückig verbundenen Segmente bevorzugt insgesamt einen in breitem Wortsinn wellenähnlichen Verlauf des Kanaldielenprofils aus, wobei vorzugsweise an eine zumindest im Wesentlichen Rechteck-Wellenform oder Trapez-Wellenform als Grundform gedacht ist. Vorzugsweise kann die Wandstärke der Kanaldiele in der Größenordnung von wenigen Millimetern liegen, bspw. in verschiedenen Querschnittssegmenten etwa 4 oder 6 mm betragen, wobei aber auch andere Wandstärken möglich wären. Zufolge des beschriebenen, im Querschnitt wellenartigen Profils der Kanaldiele erstreckt sich deren Wand nicht nur in einer sog. Querschnittlängsrichtung, sondern dabei auch dazu quer gerichtet wellen- oder stufenartig zwischen den beiden Profilseiten mehrfach hin und her. Zur zweckmäßigen Ausgestaltung ist bevorzugt, dass die hinterschnittene Nut an einem sich zumindest im Wesentlichen in bzw. parallel zu einer Querschnittslängsrichtung erstreckenden Querschnittssegment vorgesehen ist, das als U-Steg mit zwei damit verbundenen, U-Schenkel bildenden Querschnittssegmenten einen ersten, vorzugsweise in Bezug auf die Querschnittslängsrichtung mittleren, im Wesentlichen U-profilartigen Querschnittsbereich ausbildet, wobei die Nut und der U-profilartige Querschnittsbereich zu einander gegenüberliegenden Profilseiten hin geöffnet sind. Wenn das der Nut insofern zugeordnete Querschnittssegment eine ebene Wandfläche aufweist, kann diese als Führungsfläche beim Einsetzen in die Kammer einer Kammerplatte dienen. Es besteht die Möglichkeit, dass die Wandstärke dieses Querschnittssegmentes kleiner als die Tiefe der daran vorgesehenen Nut ist, wobei die Nuttiefe sogar im Bereich eines Mehrfachen der Wandstärke liegen kann. Dies bedeutet, dass das Querschnittssegment die besagte Nut im Bereich eines Vorsprunges bzw. eine Ausbauchung aufweisen kann, welche sich als eine Umrandung der Nut von dem U-Steg bzw. von dem entsprechenden Querschnittssegment ausgehend in das hohle Innere des U-profilartigen Querschnittsbereiches hinein erstreckt. Auch besteht die Möglichkeit, dass der Querschnitt in seiner Querschnittslängsrichtung im Bereich seiner beiden Längsenden je einen endseitigen U-profilartigen Querschnittsbereich umfasst, wobei diese beiden Querschnittsbereiche je einen sich zumindest im Wesentlichen in bzw. parallel zu der Querschnittslängsrichtung erstreckenden U-Steg und je zwei daran anschließende U-Schenkel aufweisen und zur einander gleichen Profil- bzw. Querschnittsseite hin offen sind, wobei deren jeweiliger, in Querschnittslängsrichtung der Querschnittsmitte zugewandter U-Schenkel in ein sich zumindest im Wesentlichen in bzw. parallel zur Profillängsrichtung erstreckendes Querschnittssegment, vorzugsweise in den U-Steg des mittleren U-profilartigen Querschnittsbereichs, übergeht, wobei das freie Ende der jeweiligen, in Querschnittslängsrichtung von der Querschnittsmitte abgewandten (also endseitigen) U-Schenkel in einem quer zu der Querschnittslängsrichtung (d.h. in Querschnittsquerrichtung) gemessenen Abstand von der von der Querschnittsmitte abgewandten Außenseite des sich im Wesentlichen in bzw. parallel zur Profillängsrichtung erstreckenden Profilsegments liegt, der gleich oder etwas größer als die Wandstärke der U-Stege der endseitigen U-profilartigen Querschnittsbereiche ist. Werden mehrere solcher drehsymmetrisch ausgebildeter Kanaldielen mit abwechselnd um eine halbe Umdrehung verdrehtem Querschnitt in eine Kammer einer Kammerplatte eingesetzt, lässt sich mittels der endseitigen U-Schenkel ein gegenseitiger formschlüssiger Eingriff zwischen benachbarten Kanaldielen erreichen bei zugleich hoher Überlappung der endseitigen U-Schenkel, wodurch das Ausrieseln von bspw. Sand oder dergleichen verhindert werden kann. Auf diese Weise kann auf eine filigrane Verbindungs- bzw. Schlossausbildung, die für die bevorzugte Anwendung an Kammerplatten zu sensibel wäre, verzichtet werden. Wenn die U-Stege bzw. insofern mittleren Querschnittssegmente der endseitigen U-profilartigen Querschnittsbereiche profilaußenseitig eine ebene Wandfläche aufweisen, können diese ebenfalls als, der vorgenannten mittleren führenden Wandfläche gegenüberliegende, Führungsflächen beim Einsetzen in die Kammerplatte dienen. Insbesondere lässt sich in Querschnittsquerrichtung durch geeignete Wahl der Abmessungen eine Abstimmung an die Kammerbreite zur Erzielung einer spielarmen Aufnahme erreichen. Die Kanaldielen sind dann in Querschnittsquerrichtung bzw. Kammerbreitenrichtung quasi selbstzentrierend und selbstführend. Insbesondere können derartige Kanaldielen auch in der Kammer bzw. im Aufnahmespalt von Kammerplatten, welche keine gesonderten Führungen für die Kanaldielen aufweisen, eingesetzt werden. Die Alu-Dielen können an beliebiger Stelle darin ineinander eingreifend eingestellt werden und werden dazu vorher zueinander abwechselnd um 180° im Querschnitt verdreht ausgerichtet, wodurch sie automatisch eine überlappende und dichte Verbauwand bilden. Eine kompakte Bauform der Kanaldiele wird erreicht, wenn je ein U-Schenkel des zuvor genannten mittleren, im Wesentlichen U-profilartigen Querschnittsbereichs je zugleich einen U-Schenkel eines der beiden endseitigen U-profilartigen Querschnittsbereiche ausbildet, d. h. mit diesem identisch ist. Auch ermöglicht eine derartige Gestaltung vorteilhaft, dass bezüglich einer geometrischen Bezugsachse, die sich in bzw. parallel zu der Querschnittslängsrichtung durch den Querschnittsschwerpunkt erstreckt, die beiden Widerstandsmomente gegen Biegung, die als Quotient aus dem der Bezugsachse zugeordneten Querschnitts-Flächenträgheitsmoment und je einem der zugeordneten Querschnittsrandabstände resultieren, zueinander gleich oder im Wesentlichen gleich groß sind. Bezüglich dieser Bezugsachse können also das sog. obere Widerstandsmoment und das sog. untere Widerstandsmoment praktisch ausgeglichen sein, was wiederum Vorteile für den beschriebenen alternierend um 180° verdrehten Einbau bietet.As already mentioned, the cross-section of the channel dumbbells in the cross-sectional plane oriented transversely to its plank longitudinal direction has a plurality of cross-sectional segments oriented in different directions in this cross-sectional plane. These are preferably comparatively thin-walled cross-sectional segments in comparison to the cross-sectional dimensions in the cross-sectional longitudinal and width directions. Within the cross-sectional plane, one or more of these segments can have an almost arbitrary course, for example straight or curved, for example also rounded. In this case, the segments integrally connected to one another preferably preferably form a generally wave-like course of the channel edge profile in a broad sense of the word, wherein an essentially at least substantially rectangular waveform or trapezoidal waveform is preferably intended as the basic shape. Preferably, the wall thickness of the channel dumbbells may be on the order of a few millimeters, for example, be about 4 or 6 mm in different cross-sectional segments, but other wall thicknesses would be possible. According to the described, in cross-section wave-like profile of the channel planks, the wall extends not only in a so-called. Cross-sectional longitudinal direction, but also directed to crosswise wave or stepwise between the two profile pages repeatedly back and forth. For expedient embodiment, it is preferred that the undercut groove is provided on a cross-sectional segment extending at least substantially in or parallel to a cross-sectional longitudinal direction, which as a U-web with two cross-sectional segments forming U-legs has a first, preferably with respect to the cross-sectional longitudinal direction forms a central, substantially U-profile-like cross-sectional area, wherein the groove and the U-profile-like cross-sectional area are open to opposite profile sides. If the cross-sectional segment associated with the groove has a flat wall surface, this can serve as a guide surface when inserted into the chamber of a chamber plate. There is the possibility that the wall thickness of this cross-sectional segment is smaller than the depth of the groove provided thereon, wherein the groove depth may even be in the range of a multiple of the wall thickness. This means that the cross-sectional segment can have the said groove in the region of a projection or bulge which extends as a border of the groove from the U-web or from the corresponding cross-sectional segment into the hollow interior of the U-profile-like cross-sectional region , There is also the possibility that the cross-section in its cross-sectional longitudinal direction in the region of its two longitudinal ends each include an end-side U-profile-like cross-sectional area, wherein these two cross-sectional areas depending on a at least substantially in or parallel to the cross-sectional longitudinal direction extending U-web and two each have subsequent U-legs and the same profile or cross-sectional side are open to each other, wherein their respective, in the cross-sectional longitudinal direction of the cross-section center facing U-legs in a at least substantially in or parallel to the profile longitudinal direction extending cross-sectional segment, preferably in the U Bridge of the middle U-profile-like cross-sectional area, passes, with the free End of the respective, in the cross-sectional longitudinal direction of the cross-sectional center facing away (ie end) U-legs in a transversely to the cross-sectional longitudinal direction (ie in cross-sectional transverse direction) measured distance from the side facing away from the cross-sectional center outside of the extending substantially in or parallel to the profile longitudinal profile segment which is equal to or slightly larger than the wall thickness of the U-webs of the end-side U-profile-like cross-sectional areas. If a plurality of such rotationally symmetrical trained channel boards with alternately twisted by half a revolution cross section in a chamber of a chamber plate can be achieved by means of the end U-legs mutual positive engagement between adjacent channel boards at the same time high overlap of the end U-legs, causing the trickling For example, sand or the like can be prevented. In this way, it is possible to dispense with a filigree connection or latch formation which would be too sensitive for the preferred application to chamber plates. If the U-webs or in this respect average cross-sectional segments of the end U-profile-like cross-sectional areas profile outside have a flat wall surface, they can also serve as, the aforementioned middle leading wall surface, guide surfaces when inserted into the chamber plate. In particular, can be achieved in cross-sectional direction by suitable choice of the dimensions of a vote to the chamber width to achieve a low-play recording. The channel boards are then quasi self-centering and self-guiding in cross-sectional transverse direction or chamber width direction. In particular, such channel boards can also be used in the chamber or in the receiving gap of chamber plates, which have no separate guides for the channel boards. The aluminum planks can be set at any point in meshing with each other and are previously aligned alternately rotated by 180 ° in cross-section, thereby automatically forming an overlapping and dense Verbauwand. A compact design of the channel dowels is achieved if ever a U-leg of the aforementioned mean, substantially U-profile-like cross-sectional area at the same time forms a U-leg of one of the two end-side U-profile-like cross-sectional areas, that is identical to this. Such a configuration also advantageously allows the two moments of resistance against bending to be determined with respect to a geometric reference axis which extends in or parallel to the cross-sectional longitudinal direction through the cross-sectional center of gravity, which is the quotient of the cross-sectional area moment of inertia assigned to the reference axis and one of the assigned cross-sectional edge distances result, are equal to each other or substantially the same size. With regard to this reference axis, therefore, the so-called upper resistance moment and the so-called lower resistance moment can be practically compensated, which in turn offers advantages for the above-described alternately twisted installation of 180 °.
Gemäß einem weiteren Aspekt betrifft die Erfindung eine Kammerplatte, vorzugsweise für eine Kammerplatten-Verbaueinheit, aufweisend zwei parallel voneinander beabstandete Kammerwände, bspw. Bohlen, die mit ihren einander zuweisenden Wandoberflächen einen parallelflächig berandeten Zwischenraum, vorzugsweise zur Aufnahme von einer oder mehreren Kanaldielen, begrenzen, und aufweisend auf einer Plattenseite im Bereich beider Längsenden Anschlussmittel, vorzugsweise zum Anschluss je einer längenverstellbaren Stützstrebe (bspw. sog. Kanalstrebe).According to a further aspect, the invention relates to a chamber plate, preferably for a chamber plate shoring unit, comprising two mutually parallel spaced chamber walls, for example. Planks, which bound with their mutually facing wall surfaces a parallel surface bounded space, preferably for receiving one or more channel boards, and having on a plate side in the region of both longitudinal ends connecting means, preferably for connecting each a length-adjustable support strut (eg., so-called channel strut).
Derartige Kammerplatten sind im Stand der Technik, wie oben beschrieben, als Stahl-Kammerplatten bekannt, wobei die ebenfalls erläuterten Einschränkungen bestehen. Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine derartige Kammerplatte vorteilhaft weiterzubilden, so dass die genannten Nachteile möglichst vermieden werden können.Such chamber plates are known in the art, as described above, as steel chamber plates, with the limitations also explained.

Die Aufgabe wird gemäß einem ersten erfindungsgemäßen Lösungsvorschlag zunächst und im Wesentlichen in Verbindung mit dem Merkmal gelöst, dass die Kammerplatte aus Aluminium und/ oder Aluminiumlegierung hergestellt ist. Dadurch resultiert ein geringeres Gewicht, so dass die Kammerplatte leichter handhabbar wird. Eine zweckmäßige Weiterbildung sieht vor, dass es sich bei den Kammerwänden um aus Leichtmetall (insbesondere Alu bzw. Aluminiumlegierung) hergestellte innen hohle Kastenprofile handelt, wie in der Beschreibung der Figuren näher dargestellt. Auf diese Weise lässt sich bei gleichzeitig niedrigem Gewicht eine hohe Stabilität erreichen.The object is achieved according to a first proposed solution according to the invention first and essentially in conjunction with the feature that the chamber plate is made of aluminum and / or aluminum alloy. This results in a lower weight, so that the chamber plate is easier to handle. An expedient development provides that the chamber walls are made of light metal (in particular aluminum or aluminum alloy) produced inside hollow box sections, as shown in more detail in the description of the figures. In this way, high stability can be achieved while maintaining low weight.

Eine derartige Kammerplatte besitzt somit erfindungsgemäß einen im Wesentlichen zweiteiligen Aufbau, d.h. lässt sich zerlegen, so dass die Bestandteile aufgrund ihres jeweils vergleichsweise geringeren Einzelgewichts leichter transportiert werden können. Ein Vorteil ist auch, dass eine solche Kammerplatte zerlegt werden kann, um die Innenwände der Kammer (welche zur Aufnahme von Kanaldielen dienen können) zu reinigen oder um bspw. eine beschädigte einzelne Wand zu ersetzen. Bevorzugt können auch hier die beiden Kammerwände, die Pfosten und die Stützprofile zumindest im Wesentlichen aus Aluminium und/oder aus Aluminiumlegierung hergestellt sein, so dass auch die Kammerplatte insgesamt aufgrund ihres geringen Gewichts von Personen ohne schwere Hebemittel (bspw. Bagger) gehandhabt werden kann. Insbesondere ist bevorzugt, dass es sich bei der genannten ersten, den Anschlussmitteln zugewandten Kammerwand mit ihren beiden Pfosten um die aus

Bevorzugt ist im Rahmen der Erfindung eine Verwendung der zuvor beschriebenen Kammerplatten und Kanaldielen bzw. Kammerplatten-Verbaueinheiten als sog.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine derartige Kammerplatten-Verbaueinheit vorteilhaft weiterzubilden, so dass insbesondere die vorgenannte Einschränkung vermieden werden kann.Against this background, the invention has the object, advantageously further develop such a chamber plate Verbaueinheit, so that in particular the aforementioned limitation can be avoided.
Die Aufgabe ist erfindungsgemäß zunächst und im Wesentlichen in Verbindung mit den Merkmalen gelöst, dass ein zu ihrer Dielenlängsrichtung senkrechter Querschnitt der Kanaldielen in seiner Querschnittslängsrichtung im Bereich seiner beiden Längsenden je einen endseitigen U-profilartigen Querschnittsbereich aufweist, die je einen sich zumindest im Wesentlichen in bzw. parallel zur der Querschnittslängsrichtung erstreckenden U-Steg und je zwei daran anschließende U-Schenkel aufweisen und die zur gleichen Profilseite hin offen sind, wobei deren jeweiliger, in Querschnittlängsrichtung der Querschnittsmitte zugewandter U-Schenkel in ein sich zumindest im Wesentlichen in bzw. parallel zur Querschnittslängsrichtung erstreckendes Querschnittssegment, insbesondere in einen U-Steg eines mittleren U-profilartigen Querschnittsbereichs, übergeht, wobei das freie Ende der jeweiligen, in Querschnittslängsrichtung von der Querschnittsmitte abgewandten (also endseitigen) U-Schenkel in einem quer zu der Querschnittslängsrichtung (d.h. in Querschnittsquerrichtung) gemessenen Abstand von der von der Querschnittsmitte abgewandten Außenseite des sich im Wesentlichen in bzw. parallel zur Querschnittslängsrichtung erstreckenden Querschnittssegmentes liegt, der gleich oder etwas größer als die Wandstärke der U-Stege der endseitigen U-profilartigen Querschnittsbereiche ist, und wobei die beiden einander zuweisenden, den Zwischenraum für die Kanaldielen berandenden Wandoberflächen keine aus der Wandebene hervorstehenden Führungen für Kanaldielen aufweisen.The object is achieved according to the invention initially and essentially in conjunction with the features that a perpendicular to their Dielenlängsrichtung cross-section of the channel boards in its cross-sectional longitudinal direction in the region of its two longitudinal ends each have an end U-profile-like cross-sectional area, each one at least substantially in or parallel to the cross-sectional longitudinal direction extending U-web and two adjoining U-legs and which are open to the same profile side, with their respective, in the cross-sectional longitudinal direction of the cross-section center facing U-legs in an at least substantially in or parallel to Cross-sectional longitudinal direction extending cross-sectional segment, in particular in a U-web of a central U-profile-like cross-sectional area, merges, wherein the free end of the respective, in the longitudinal direction of the cross-section of the cross-section center facing away (ie end) U-legs in a m transversely to the cross-sectional longitudinal direction (ie in cross-sectional transverse direction) measured distance from that facing away from the cross-sectional center Outside of the substantially in or parallel to the cross-sectional longitudinal direction extending cross-sectional segment is equal to or slightly greater than the wall thickness of the U-webs of the end U-profile-like cross-sectional areas, and wherein the two facing each other, the space for the Kanaldielen bordering wall surfaces no have from the wall level protruding guides for channel planks.
