Description

Die Erfindung betrifft einen aufrollbaren Bodenbelag einer Verkehrsfläche, bestehend aus einzelnen Tragelementen, die jeweils zwei parallele Längskanten aufweisen, an denen und um die sie, auf Zug und Druck beanspruchbar, gelenkig miteinander verbunden sind.The invention relates to a roll-up floor covering of a traffic area, consisting of individual support elements, each having two parallel longitudinal edges, on which and around which they are articulated to one another, which can be subjected to tension and pressure.

Derartige Bodenbeläge werden angewandt, um z. B. Gelände mit weichem und/oder nassem Untergrund für schwere Transportgeräte oder ähnliches zugänglich zu machen. Zum Befahren von zweispurigen Reifen- oder Kettenfahrzeugen werden entweder Rollbahnen verwendet, die die erforderliche Breite - z. B. 4,6 m - aufweisen, oder zwei getrennte Fahrbahnspuren. Während die in voller Breite verlegte Rollbahn Punktlasten besser auf den Untergrund verteilt, hat die Verwendung von zwei getrennten Fahrbahnspuren den Vorteil des geringeren Transportgewichts. Zum Landen von Hubschraubern können Bodenbeläge verwendet werden, deren Breite in der Größenordnung der Länge liegt.Such floor coverings are used to z. B. make terrain with soft and / or wet ground accessible for heavy transport equipment or the like. To drive on two-lane tire or tracked vehicles either runways are used, the required width - z. B. 4.6 m - or two separate lanes. While the full width of the runway distributes point loads better on the ground, the use of two separate lanes has the advantage of the lower transport weight. Flooring whose width is of the order of length can be used to land helicopters.

Die Bodenbeläge können aber auch - bei großen Flächen gegebenenfalls unter Zuhilfenahme von einzelnen Längsträgern - über Vertiefungen wie Baugruben, Gräben od. dgl. verlegt werden.However, the floor coverings can also be laid over recesses such as excavation pits, trenches or the like in the case of large areas, if necessary with the aid of individual longitudinal members.

Die Erfindung geht aus von einem aufrollbaren Bodenbelag, dessen Tragelemente eine - im Querschnitt gesehen - nach oben und nach unten offene wellenförmige Struktur aufweisen, wobei die Wellenberge und Wellentäler mit jeweils zwei Ecken und einer dazwischenliegenden Geraden dargestellt sind.The invention is based on a roll-up floor covering, the support elements of which — seen in cross section — have an undulating structure which is open upwards and downwards, the wave crests and wave troughs each being shown with two corners and a straight line in between.

Parallel zu der wellenförmigen Struktur weisen die bekannten Tragelemente an der einen Längskante einen Wulst und an der anderen Längskante eine klauenförmige Vertiefung auf. Dieses bekannte Profil ist zwar äußerst leicht, es hat aber entscheidende, von seinem Aufbau herrührende Nachteile. Für den Fall, daß die Zwischenräume zwischen zwei Wellenbergen oder -tälern außen größer bzw. weiter als innen sind, ist der Anteil der unmittelbar tragenden Fläche an der gesamten Fläche relativ gering. Sind dagegen die Zwischenräume außen geringer als innen - sogenannte Schwalbenschwanzform - so wird der weiche, dort hineingedrückte Untergrund dort auch festgehalten. Bei einer erneuten Verwendung des bekannten Belages müssen die Tragelemente, wenn das geringe Eigengewicht der bekannten Rollbahn genutzt werden soll, wieder gründlich gesäubert werden. Diese Forderung ist aber im Gelände nur äußerst schwierig zu erfüllen. Durch die einlagige Querschnittsgestaltung neigen die Tragkörper darüber hinaus - insbesondere bei ungünstigen Lastenverhältnissen, wie z. B. punktförmiger Lasteinwirkung - zu Brüchen.Parallel to the wave-shaped structure, the known support elements have a bead on one longitudinal edge and a claw-shaped depression on the other longitudinal edge. This known profile is extremely light, but it has decisive disadvantages arising from its structure. In the event that the gaps between two wave crests or valleys are larger or wider on the outside than on the inside, the proportion of the directly bearing surface in the total area is relatively small. If, on the other hand, the gaps on the outside are smaller than on the inside - the so-called dovetail shape - the soft surface pressed in there is also held there. When the known covering is used again, the support elements have to be thoroughly cleaned again if the low weight of the known taxiway is to be used. However, this requirement is extremely difficult to meet in the field. Due to the single-layer cross-sectional design, the support body also incline - especially under unfavorable load conditions, such as. B. point load - to breaks.

Aus der DE-B-14 59 718 ist ein Bodenbelag mit einzelnen, vor Ort zu montierenden Tragelementen mit hohlem Querschnitt bekannt, der eine Deckplatte, eine Bodenplatte und dazwischen verlaufende senkrechte Stege aufweist. Aus der DE-U-1838412 ist ferner ein Bodenbelag mit Tragkörpern bekannt, die zwischen der Deckplatte und der Bodenplatte unter etwa 45° verlaufende Versteifungsscheiben aufweisen und die durch sogenannte Schloßkonstruktionen fest miteinander verbunden sind. Bei den beiden bekannten Tragelementen bzw. Tragkörpern ist die Bodenplatte eben ausgebildet. Dies führt bei unebenem Gelände zu örtlich unterschiedlichen Auflagedrücken. Außerdem weisen die Tragelemente einen nur geringen Auflagewiderstand gegen waagerechte Kräfte auf.From DE-B-14 59 718 a floor covering with individual support elements to be assembled on site with a hollow cross-section is known, which has a cover plate, a base plate and vertical webs running therebetween. From DE-U-1838412 a floor covering with supporting bodies is also known, which have stiffening disks running at approximately 45 ° between the cover plate and the base plate and which are firmly connected to one another by so-called lock constructions. In the case of the two known supporting elements or supporting bodies, the base plate is flat. This leads to locally different contact pressures on uneven terrain. In addition, the support elements have only a low contact resistance against horizontal forces.

Der Erfindung liegt die Aufgabe zugrunde, einen aufrollbaren Bodenbelag anzugeben, bei dem senkrechte Einzellasten - insbesondere bei unebenem, weichen Boden - gleichmäßig auf den Untergrund verteilt werden, der waagerechten Kräften einen hohen Widerstand in Fahrtrichtung entgegensetzt und darüber hinaus leicht zu verlegen ist.The invention has for its object to provide a roll-up flooring in which vertical individual loads - especially on uneven, soft floor - are evenly distributed on the ground, the horizontal forces oppose a high resistance in the direction of travel and is also easy to install.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Tragelemente - in einem senkrecht zu den Längskanten gelegten Querschnitt gesehen - als Hohlprofil ausgebildet sind, das einen im wesentlichen ebenen flächenförmigen Obergurt und einen von einer Ebene abweichenden flächenförmigen Untergurt aufweist, wobei der Untergurt abwechselnd sowohl Flächenteile aufweist die im Uhrzeigersinn als auch solche Flächenteile, die entgegen dem Uhrzeigersinn gegen die durch den Obergurt gegebene Ebene geneigt sind, und wobei jeweils zwei verschieden geneigte, benachbarte Flächenteile abwechselnd erhabene bzw. versenkte Knickkanten im Untergurt bilden. Einerseits bewirkt das Hohlprofil eine Erhöhung der Bruchfestigkeit der Tragelemente. Auf der anderen Seite ergibt sich durch die senkrechte Komponente der Flächenteile des Untergurtes die Möglichkeit, daß punktförmig angehäufter Untergrund und insbesondere auch einzelne Teile davon, wie Steine, Wurzeln, usw., schräg nach oben und damit gleichzeitig zur Seite gleiten können. Diese Ausgleichsbewegung des Untergrundes wird sich im wesentlichen solange fortsetzen, bis sich ein gleichmäßiger Auflagedruck unter der Fläche der Tragelemente ergeben hat. Gleichzeitig ergeben die schräg verlaufenden Flächenteile einen erhöhten Widerstand in Querrichtung der Tragelemente - d. h. in Längsrichtung der Fahr- bzw. Rollbahn - der durch die Ausbildung von Rippen nach Anspruch 2 noch erhöht werden kann.This object is achieved in that the support elements - seen in a cross section perpendicular to the longitudinal edges - are designed as a hollow profile which has a substantially flat, flat top flange and a flat bottom flange which deviates from a plane, the bottom flange alternately having both surface parts the clockwise and also those parts of the surface which are inclined counter-clockwise against the plane given by the upper chord, and where two differently inclined, adjacent parts of the surface alternately form raised or recessed buckling edges in the lower chord. On the one hand, the hollow profile increases the breaking strength of the support elements. On the other hand, due to the vertical component of the surface parts of the lower flange, there is the possibility that point-accumulated subsurface and in particular also individual parts thereof, such as stones, roots, etc., can slide diagonally upwards and thus simultaneously to the side. This compensating movement of the subsoil will continue essentially until a uniform contact pressure has resulted under the surface of the support elements. At the same time, the sloping surface parts result in increased resistance in the transverse direction of the support elements - d. H. in the longitudinal direction of the road or taxiway - which can be increased by the formation of ribs according to claim 2.

Durch die Anordnung von Versteifungsteilen nach Anspruch 3 wird die Festigkeit insbesondere großflächiger Tragelemente wesentlich erhöht.By arranging stiffening parts according to claim 3, the strength of large-area support elements in particular is significantly increased.

Durch die Ausbildung der Tragelemente nach Anspruch 4 wird deren Eigengewicht gering gehalten, was einer leichten Handhabung des Bodenbelages entgegenkommt. Mit der Ausbildung der Tragelemente nach Anspruch 5 wird in einfacher Weise ermöglicht, Dübel in die Vertiefungen zu setzen, und so ein seitliches Verrutschen der einzelnen Tragelemente gegeneinander zu verhindern. Der hierzu erforderliche schräge Schnitt der Stirnseiten erfordert im wesentlichen lediglich den gleichen Aufwand wie ein senkrechter Schnitt. Eine Auseckung oder Ausklinkung der Wulstteile an der entsprechenden Stelle ist damit nicht erforderlich.By designing the support elements according to claim 4, their own weight is kept low, which accommodates easy handling of the floor covering. With the design of the support elements according to claim 5, dowels in the wells are made possible in a simple manner to set, and thus to prevent the individual support elements from sliding sideways. The oblique cut of the end faces required for this essentially only requires the same effort as a vertical cut. It is therefore not necessary to cover or notch the bead parts at the corresponding point.

Durch das Ausschäumen der Tragelemente nach Anspruch 6 und durch das Abdichten nach Anspruch 7 wird vermieden, daß sich weicher Schlamm seitlich in die Hohlräume schiebt und das Gewicht der Tragelemente nachträglich erhöht und damit die Handhabung des ganzen Bodenbelages erschwert. Bei entsprechender Dimensionierung kann der Bodenbelag bei dieser Ausbildung für sich sogar schwimmfähig sein.By foaming the support elements according to claim 6 and by sealing according to claim 7, it is avoided that soft mud pushes laterally into the cavities and subsequently increases the weight of the support elements and thus complicates the handling of the entire floor covering. With appropriate dimensioning, the floor covering can even float in this training.

Die Ausbildung der Tragelemente nach Anspruch 8 dient der sicheren Übertragung von waagerechten Kräften von Fahrzeugen auf die Fahrbahn und umgekehrt.The design of the support elements according to claim 8 is used for the safe transmission of horizontal forces from vehicles to the road and vice versa.

  • 2 the roadway in a partial side view with omission of lateral fasteners,
  • 3 the roadway in a partial plan view,
  • Fig. 4 shows the adjacent ends of two support elements in an upwardly angled position in side view and
  • Fig. 5 shows a large floor covering in plan view.

Der Bodenbelag der Fahrbahn in der Ausführungsform nach Fig. 1 besteht aus mehreren hintereinander angeordneten Tragelementen oder Paneelen 1. Dieser Belag kann sowohl eine von zwei Fahrspuren mit geringer Breite B von je etwa 1,4 m als auch eine Fahrbahn mit einer Breite B von z. B. 4,6 m im entrollten Zustand darstellen. Die Länge der Fahrspur bzw. Fahrbahn ist mit L angegeben. Die Länge der Paneele 1 ist gleich der Breite B der Fahrspur bzw. Fahrbahn. Der effektive Abstand der Paneele bzw. deren Teilung ist mit t bezeichnet. An den Enden der Fahrspur bzw. Fahrbahn können besondere (hier nicht weiter dargestellte) Auffahrpaneele angeordnet sein.The floor covering of the carriageway in the embodiment according to FIG. 1 consists of a plurality of support elements or panels 1 arranged one behind the other. This pavement can be either one of two lanes with a small width B of about 1.4 m each, or a carriageway with a width B of z . B. represent 4.6 m in the unrolled state. The length of the lane or lane is indicated by L. The length of the panels 1 is equal to the width B of the lane or lane. The effective spacing of the panels or their division is denoted by t. At the ends of the lane or lane, special drive-on panels (not shown further here) can be arranged.

Die Paneele 1 sind als Hohlkörper ausgebildet und weisen eine Deckplatte bzw. einen flächenförmigen Obergurt 10 und einen flächenförmigen Untergurt 11 auf. Der Untergurt 11 besteht aus verschieden geneigten Flächenteilen 12 bis 15, die abwechselnd im und entgegen dem Uhrzeigensinn gegen die Ebene der Fahrbahn bzw. der Deckplatte 10 geneigt sind (12, 14 bzw. 13, 15). Jeweils zwei verschieden geneigte Flächenteile (12, 13 bzw. 13, 14) bilden abwechselnd eine erhabene und eine vertiefte Knickkante 16 bzw. 17 im Untergurt 11. Zwischen dem Obergurt 10 und dem Untergurt 11 sind schräg angeordnete tragwerkartige Flächenteile 19 bis 25 angeordnet und mit diesen fest verbunden. Mit dem Untergurt sind diese Flächenteile vorzugsweise an den Knickkanten 16, 17 verbunden.The panels 1 are designed as hollow bodies and have a cover plate or a flat top flange 10 and a flat bottom flange 11. The lower flange 11 consists of differently inclined surface parts 12 to 15 which are alternately inclined clockwise and counterclockwise against the plane of the roadway or the cover plate 10 (12, 14 or 13, 15). Each two differently inclined surface parts (12, 13 and 13, 14) alternately form a raised and a recessed fold edge 16 and 17 in the lower flange 11. Between the upper flange 10 and the lower flange 11, obliquely arranged structural parts 19 to 25 are arranged and with this firmly connected. These surface parts are preferably connected to the lower flange at the buckling edges 16, 17.

Die Flächenteile 12 bis 15 und 19 bis 25 verlaufen in Längsrichtung der Paneele 1, die wiederum quer zur Längsrichtung der Fahrbahn verläuft. Die Paneele 1 haben an ihrer einen Längs- bzw. Seitenkante einen zylindrischen Wulst 26 und an der jeweils anderen Längsseite eine klauenförmige, hohlzylindrische Vertiefung 27. Der Wulst 26 ist über einen halsförmigen Steg 28 mit dem Paneel 1 verbunden. Die Vertiefung 27 weist eine in Längsrichtung der Paneele verlaufende Öffnung 29 auf.The surface parts 12 to 15 and 19 to 25 run in the longitudinal direction of the panels 1, which in turn runs transversely to the longitudinal direction of the carriageway. The panels 1 have a cylindrical bead 26 on one longitudinal or side edge and a claw-shaped, hollow cylindrical recess 27 on the other longitudinal side in each case. The bead 26 is connected to the panel 1 via a neck-shaped web 28. The recess 27 has an opening 29 running in the longitudinal direction of the panels.

Der Obergurt 10 und der Untergurt 11 sind mit in Längsrichtung der Paneele verlaufenden, außenliegenden Rippen 31 bzw. 32 versehen - beim Obergurt vorzugsweise an den Stellen, wo die fachwerkartigen Flächenteile 18, 19, usw. anstoßen und beim Untergurt vorzugsweise an den erhabenen Knickkanten 16.The upper chord 10 and the lower chord 11 are provided with external ribs 31 and 32 running in the longitudinal direction of the panels - in the case of the upper chord preferably at the points where the framework-like surface parts 18, 19, etc. abut, and in the lower chord preferably on the raised buckling edges 16 .

Die Paneele 1 sind vorzugsweise als Leichtmetall-Strangpressprofil ausgebildet. Als Werkstoff kommt hierbei z. B. AIMgSi 1 in Frage. Die durch den Obergurt 10, den Untergurt 11 und die fachwerkartigen Flächenteile 19 bis 25 gebildeten Hohlräume können mit Polyurethan ausgeschäumt sein.The panels 1 are preferably designed as a light metal extruded profile. The material here is z. B. AIMgSi 1 in question. The cavities formed by the top flange 10, the bottom flange 11 and the framework-like surface parts 19 to 25 can be foamed with polyurethane.

Der Wulst 26 kann in die Vertiefung 27 hineingeschoben werden. Die Weite der Öffnung 29 ist wesentlich größer als die Dicke des Steges 28. Dadurch ergibt sich die zum Aufrollen der Fahrspur bzw. Fahrbahn notwendige Gelenkigkeit der Paneele 1 (vgl. Fig. 4). Damit die Paneele 1 in ihrer eigenen Längsrichtung - also quer zur Längsrichtung der Fahrbahn - nicht gegeneinander verrutschen, sind an den Enden der Vertiefungen 27 Dübel 35 angeordnet. Die Dübel 35 sind beispielsweise von der Art, daß ein Konus 36 eine mit einem Innenkonus 37 versehene, gespaltene Hülse 38 gegen die Wandung der Vertiefung drückt. Die Paneele 1 sind an der Längsseite mit dem Wulst 26 im wesentlichen um die Länge des Dübels 35 zurückgenommen. Die Längskante mit dem Wulst 26 ist bei den Paneelen in der Ausführungsform nach Fig. 1 demnach um zweimal die Länge des Dübels 35 kürzer als die Längsseite mit der Vertiefung 27.The bead 26 can be pushed into the recess 27. The width of the opening 29 is significantly greater than the thickness of the web 28. This results in the articulation of the panels 1 required for rolling up the lane or roadway (cf. FIG. 4). So that the panels 1 do not slip against each other in their own longitudinal direction - that is, transversely to the longitudinal direction of the roadway - 27 dowels 35 are arranged at the ends of the depressions. The dowels 35 are, for example, of the type that a cone 36 presses a split sleeve 38 provided with an inner cone 37 against the wall of the recess. The panels 1 are withdrawn on the long side with the bead 26 essentially by the length of the dowel 35. The longitudinal edge with the bulge 26 in the panels in the embodiment according to FIG. 1 is therefore twice the length of the dowel 35 shorter than the long side with the recess 27.

Im einfachsten Fall kann diese Zurücknahme bzw. Verkürzung durch einen schrägen Schnitt erreicht werden, der derart gelegt ist, daß die Stirnseite 41 gegen die Seitenkante mit der Vertiefung 27 einen solchen Winkel 8 bildet, der kleiner als 90° ist.In the simplest case, this withdrawal or shortening can be achieved by an oblique cut, which is made such that the end face 41 forms an angle 8 with the recess 27 against the side edge, which is less than 90 °.

Die Stirnseiten 41 können mit entsprechenden Abdeckblechen 42, die im wesentlichen die gleiche Form wie der Querschnitt der Paneele 1 aufweisen, wasserdicht verschweißt sein.The end faces 41 can be welded in a watertight manner to corresponding cover plates 42, which have essentially the same shape as the cross section of the panels 1.

Bei dem Ausführungsbeispiel nach Fig. 5 sind die Tragkörper oder Paneele zu einem aufrollbaren "Teppich" zusammengesetzt, dabei sind jeweils mehrere Paneele in einer Reihe oder Zeile - in ihrer eigenen Längsrichtung - hintereinander zusammengesetzt. Mehrere Zeilen bilden den gesamten Teppich mit der Länge L und der Breite B'.In the exemplary embodiment according to FIG. 5, the supporting bodies or panels are assembled to form a “carpet” that can be rolled up, in each case a plurality of panels in a row or row — in their own longitudinal direction — are assembled one behind the other. Several lines form the entire carpet with the length L and the width B '.

Jede zweite Zeile weist zwei - allgemein : n-Paneele 1a, 1 mit der Länge B auf. Dazwischen liegen Zeilen, die jeweils ein - allgemein : (n - 1)-Paneele 1 c der Länge B und zwei Paneele 1d. 1e der Länge B/2 aufweisen.Every second row has two - generally: n-panels 1a, 1 with the length B. In between are rows, each of which - generally: (n - 1) panels 1 c of length B and two panels 1d. 1e of length B / 2.

Die Paneele 1a bis 1e weisen den gleichen Querschnitt auf wie die beschriebenen Paneele 1. Die Wülste 26 sind jeweils in die Vertiefung 27 geschoben. Gegen unbeabsichtigtes Verschieben sind die Paneele an der Außenseite des Teppichs in der beschriebenen Weise durch Dübel 35 gesichert, wozu die Stirnenden 41 der Paneele jeweils an der Außenseite des Teppichs unter einem Winkel 8 gegen die Seitenkante mit der Vertiefung 27 von 8 < 90° angeordnet sind.The panels 1a to 1e have the same cross section as the panels 1 described. The beads 26 are each pushed into the recess 27. The panels on the outside of the carpet are secured against inadvertent movement in the manner described by dowels 35, for which purpose the ends 41 of the panels are each arranged on the outside of the carpet at an angle 8 against the side edge with the recess 27 of 8 <90 ° .

Im Innern des Teppichs sind die Stirnseiten 41 der Paneele senkrecht zu den Längskanten der Paneele angeordnet. Die Paneele jeweils zweier benachbarter Zeilen sind mit ihren Stirnkanten um eine halbe Paneelenlänge B/2 gegeneinander versetzt (sogenannter Klinkerverband).In the interior of the carpet, the end faces 41 of the panels are arranged perpendicular to the longitudinal edges of the panels. The panels of two adjacent rows are offset with their end edges by half a panel length B / 2 (so-called clinker bond).

Zum Zusammenhalt des ganzen Teppichs in Querrichtung sind die Paneele einiger Reihen durch Seile 44 miteinander verspannt. Dazu sind die Seile 44 durch die Hohlräume der Paneele gezogen und durch Haltelemente 45 an den Abdeckblechen 42 an den äußeren Stirnseiten 41 verankert.To hold the whole carpet together in the transverse direction, the panels of some rows are braced together by ropes 44. For this purpose, the ropes 44 are pulled through the cavities of the panels and anchored to the cover plates 42 on the outer end faces 41 by holding elements 45.
