Description

Die Erfindung betrifft ein Sektionaltor, insbesondere für Cargobehälter, mit einem an seitlichen Laufschienen geführten Torblatt aus gelenkig miteinander verbundenen Sektionen, die eine Innenschale, eine Außenschale, eine dazwischen angeordnete Dämmschicht aus Hartschaum und seitliche, in Längsrichtung der Laufschienen sich erstreckende Endkappen aufweisen, wobei die Endkappen als U-Profile ausgebildet sind und den aus der Innenschale, der Außenschale und der Dämmschicht bestehenden Formkörper umfassen. Cargobehälter bezeichnet Transportcontainer für Straßen- und Schienenfahrzeuge sowie Schiffe. Sie sind üblicherweise auf- und abladbar, wobei jedoch auch feste Aufbauten auf Straßen- und Schienenfahrzeugen im Rahmen der Erfindung nicht ausgeschlossen sein sollen.The invention relates to a sectional door, in particular for Cargo container, with one on the side rails guided door leaf made of articulated Sections that have an inner shell, an outer shell, a insulation layer made of hard foam and lateral, in the longitudinal direction of the running rails themselves have extending end caps, the end caps as U-profiles are formed and from the inner shell, the Outer shell and the existing insulating body include. Cargo container refers to transport containers for Road and rail vehicles and ships. they are Usually loadable and unloadable, but also fixed Superstructures on road and rail vehicles as part of the Invention should not be excluded.

Ein Sektionaltor des eingangs beschriebenen Aufbaus und mit der angegebenen Zweckbestimmung für Cargobehälter ist aus DE-C 197 23 158 bekannt. Die Formstabilität der das Torblatt bildenden Sektionen, die als zweischalige, einen Dämmstoff enthaltende Hohlkörper ausgebildet sind, ist ausreichend, um die bei einem Transport des Cargobehälters durch den Fahrtwind von außen auf das Torblatt wirkenden Windkräfte aufzunehmen. Bei Bremsvorgängen und insbesondere bei Unfällen besteht die Gefahr, dass die Ladung des Cargobehälters verrutscht und kurzzeitig hohe Kräfte auf die Innenseite des Torblattes einwirken. Für Straßen- und Schienenfahrzeuge wird daher die Forderung gestellt, dass ein für den Einsatz in Cargobehältern bestimmtes Torblatt einer hohen, innen auf das Torblatt wirkenden Belastung standhalten muss. Die Außenseite des Torblattes soll als möglichst glatte, für Werbeaufdrucke geeignete Fläche ausgebildet sein. Verstärkungsprofile an der Außenschale sind daher unerwünscht. An der Innenschale der Sektionen werden Verstärkungsprofile akzeptiert, doch dürfen sie nur geringfügig in den Laderaum vorstehen. Sie dürfen das Nutzvolumen des Cargobehälters nicht reduzieren. Vor allem muss ausgeschlossen sein, dass die Verstärkungsprofile beim Öffnen und Schließen des Sektionaltores an der Ladung hängen bleiben.A sectional door of the construction described at the beginning and with The stated purpose for cargo containers is off DE-C 197 23 158 known. The dimensional stability of the Sections forming the door leaf, which are double-shelled, one Hollow bodies containing insulation are formed sufficient to transport the cargo container by the wind from outside acting on the door leaf Absorb wind forces. When braking and in particular in the event of an accident, there is a risk that the cargo of the Cargo container slips and briefly high forces act on the inside of the door leaf. For road and Rail vehicles are therefore required to: a door leaf intended for use in cargo containers a high load acting on the inside of the door leaf has to withstand. The outside of the door leaf is said to be surface as smooth as possible, suitable for advertising printing be trained. Reinforcement profiles on the outer shell are therefore undesirable. On the inner shell of the sections reinforcement profiles are accepted, but they may only protrude slightly into the hold. You can do that Do not reduce the usable volume of the cargo container. Especially must be excluded that the reinforcement profiles at Opening and closing the sectional door on the load get stuck.

Der Erfindung liegt die Aufgabe zugrunde, ein für Cargobehälter geeignetes Sektionaltor anzugeben, das einer auf die Innenseite wirkenden hohen Belastung ohne Zerstörung standhält.The invention has for its object one for cargo containers specify a suitable sectional door that one on the inside acting high load without destruction withstand.

Die Aufgabe wird bei einem Sektionaltor des eingangs beschriebenen Aufbaus erfindungsgemäß dadurch gelöst,
   dass an der Innenschale der Sektionen Verstärkungsprofile befestigt sind, die sich über die gesamte Länge der Sektion bis zu den Endkappen erstrecken und mit diesen verbunden sind, und
   dass im Bereich der Endkappen Versteifungsprofile in die Dämmschicht eingesetzt sind, die mit den Endkappen verbunden sind und das Querschnittsprofil der Endkappen versteifen,
wobei die Verstärkungs- und Versteifungsprofile so aufeinander abgestimmt sind, dass die Dämmschicht bei einer zulässigen Verformung der Innenschale unter einer gleichmäßig auf die Innenschale wirkenden Prüflast, die mindestens 800 kg/m2 beträgt, und Scherbeanspruchungen, die einen Riss des Hartschaumes bewirken, von der Dämmschicht ferngehalten werden. Die zulässige Verformung der Innenschale, die sich aus einem elastisch reversiblen Anteil und einem irreversiblen Deformationsanteil zusammensetzt, wird zweckmäßig so festgelegt, dass der nach Entlastung bleibende irreversible Deformationsanteil kleiner ist als 15 mm. Bei diesem Wert ist das Torblatt noch in vollem Umfange funktionsfähig.The object is achieved according to the invention in a sectional door of the construction described at the outset by
that reinforcement profiles are attached to the inner shell of the sections, which extend over the entire length of the section and are connected to the end caps, and
that stiffening profiles are inserted into the insulation layer in the area of the end caps, which are connected to the end caps and stiffen the cross-sectional profile of the end caps,
the reinforcement and stiffening profiles are matched to one another such that the insulation layer is subjected to a permissible deformation of the inner shell under a test load that acts uniformly on the inner shell, which is at least 800 kg / m 2 , and shear stresses that cause the rigid foam to crack Insulation layer are kept away. The permissible deformation of the inner shell, which is composed of an elastically reversible component and an irreversible deformation component, is expediently determined such that the irreversible deformation component remaining after relief is less than 15 mm. At this value, the door leaf is still fully functional.

Aufgrund der Formstabilität der durch Versteifungsprofile verstärkten Endkappen wird die Außenschale der Sektionen unter Zugspannung gesetzt, wenn die Innenschale sich unter Last durchbiegt. Bei hoher Formstabilität der Endkappen nimmt die Zugspannung in der Außenschale mit zunehmender Durchbiegung der Innenschale zu. Sie wirkt einer Durchbiegung der Außenschale entgegen. Das hat zur Folge, dass die aus Hartschaum, z. B. einem Polyurethanschaum, bestehende Dämmschicht zunehmend fest zwischen Innenschale und Außenschale eingespannt wird und im Wesentlichen nur Druckkräften ausgesetzt ist. Die Erfindung beruht auf der Überlegung, dass Hartschaum hohe Druckkräfte aufnehmen kann, hingegen bei Scherbeanspruchungen reißt. Durch die erfindungsgemäße Anordnung werden Scherbeanspruchungen, die ein Reißen des Hartschaumes bewirken, von der Dämmschicht ferngehalten. Due to the dimensional stability of the stiffening profiles The outer shell of the sections is reinforced with end caps put under tension when the inner shell is under Load deflects. With high dimensional stability of the end caps the tension in the outer shell increases with increasing Deflection of the inner shell. She works one Deflection against the outer shell. As a result, that the hard foam, e.g. B. a polyurethane foam, existing insulation layer increasingly firmly between the inner shell and outer shell is clamped and essentially only Is subjected to compressive forces. The invention is based on the Consideration that hard foam absorbs high compressive forces can, however, tears under shear stresses. Through the Arrangement according to the invention are shear stresses that cause the hard foam to tear from the insulation layer kept away.

Gemäß einer bevorzugten Ausführung der Erfindung sind die Verstärkungsprofile an der sichtbaren Seite der Innenschale befestigt und weisen eine in den Innenraum des Cargobehälters vorstehende Höhe von weniger als 20 mm auf. Bevorzugt ist die Verwendung von U-förmigen Profilen mit einer Schenkelbreite von etwa 15 mm.According to a preferred embodiment of the invention Reinforcement profiles on the visible side of the inner shell attached and have one in the interior of the Cargo container protruding height of less than 20 mm. The use of U-shaped profiles is preferred a leg width of about 15 mm.

Die in den Endkappen angeordneten Versteifungsprofile bestehen zweckmäßig aus Abschnitten eines Rechteckrohres oder Hutprofils, welches einen U-förmigen Querschnitt und an die U-Schenkel angeformte, nach außen abstehende Flanschflächen aufweist. Dabei sind die Verstärkungsprofile und die Versteifungsprofile vorzugsweise durch Schrauben oder Nieten, welche Bohrungen der Innenschale durchfassen, miteinander verbunden. Die Schraub- oder Nietverbindungen sind bei einer innenseitigen Belastung des Torblatte hohen Scherbeanspruchungen ausgesetzt und bestehen daher zweckmäßig aus einem scherfesten Material, vorzugsweise einem Vergütungsstahl. Auch zur Verbindung der Außenschale mit den Endkappen sind aus einem Vergütungsstahl bestehende Nieten zweckmäßig.The stiffening profiles arranged in the end caps suitably consist of sections of a rectangular tube or hat profile, which has a U-shaped cross section and molded on the U-legs, protruding outwards Has flange surfaces. Here are the reinforcement profiles and the stiffening profiles preferably by screws or rivets that pass through the holes in the inner shell, connected with each other. The screw or rivet connections are high when the door leaf is loaded on the inside Exposed to shear stresses and therefore suitably exist made of a shear-resistant material, preferably one Quenched and tempered steel. Also for connecting the outer shell with the end caps are made of tempered steel Appropriate riveting.

Die Verstärkungsprofile können mit der Innenschale der Sektionen verklebt oder durch Nieten verbunden sein.The reinforcement profiles can be attached to the inner shell of the Sections glued or connected by rivets.

Das in Fig. 1 dargestellte Sektionaltor ist in einem Cargobehälter eingebaut, dessen boden- und oberseitige Umrisse 1 schematisch angedeutet sind. Es weist ein an seitlichen Laufschienen 2 geführtes Torblatt 3 aus gelenkig miteinander verbundenen Sektionen 4 auf, deren sandwichartiger Aufbau aus Fig. 2 ersichtlich ist. Die Sektionen 4 bestehen aus einer Innenschale 5, einer Außenschale 6, einer dazwischen angeordneten Dämmschicht 7 aus Hartschaum und weisen in Längsrichtung der Laufschienen 2 sich erstreckende, seitliche Endkappen 8 auf. Die Endkappen 8 sind als U-Profile ausgebildet und umfassen den aus der Innenschale 5, der Außenschale 6 und der Dämmschicht 7 bestehenden Formkörper.The sectional door shown in Fig. 1 is in one Cargo container installed, the bottom and top Outlines 1 are indicated schematically. It instructs one side rails 2 guided door leaf 3 from articulated interconnected sections 4, the 2 can be seen from the sandwich-like structure. The Sections 4 consist of an inner shell 5, one Outer shell 6, an insulation layer 7 arranged between them made of hard foam and point in the longitudinal direction of the running rails 2 extending, side end caps 8. The End caps 8 are designed as U-profiles and include the from the inner shell 5, the outer shell 6 and the Insulation layer 7 existing molded body.

In den Fig. 3 und 4 ist eine der das Torblatt bildenden Sektionen 4 perspektivisch sowie in einem durch die Endkappe 8 gelegten Querschnitt dargestellt. Einer vergleichenden Betrachtung der Figuren entnimmt man, dass an der Innenschale 5 der Sektion Verstärkungsprofile 9 befestigt sind, die sich über die gesamte Länge der Sektion bis zu den Endkappen 8 erstrecken und mit diesen verbunden sind. Im Bereich der Endkappen sind Versteifungsprofile 10 in die Dämmschicht 7 der Sektion eingetrieben und mit den Endkappen 8 verbunden, um das Querschnittsprofil der Endkappen 8 zu versteifen. Sie bestehen im Ausführungsbeispiel aus einem Hutprofil, das einen U-förmigen Quertschnitt und an die U-Schenkel angeformte, nach außen abstehende Flanschflächen aufweist. Als Versteifungsprofile 10 sind auch Rechteckrohrabschnitte und ähnliche Profilkörper geeignet. Die Verstärkungsprofile und die Versteifungsprofile sind im Ausführungsbeispiel durch Nieten 11, welche Bohrungen der Innenschale 5 durchfassen, miteinander verbunden. Die Außenschale 6 ist durch eine Anzahl von Nietverbindungen 12 an die Endkappe 8 und die im Bereich der Endkappen eingesetzten Versteifungsprofile 10 angeschlossen. Bei einer auf die Innenschale 5 wirkenden Last werden die Nietverbindungen 11,12 im Bereich der Endkappe 8 hohen Scherkräften ausgesetzt, so dass zumindest die im Bereich der Endkappe 8 verwendeten Befestigungsmittel 11,12 aus einem scherfesten Material, vorzugsweise einem Vergütungsstahl, bestehen sollten. Im Ausführungsbeispiel werden Edelstahlnieten 11,12 verwendet. Die Verstärkungsprofile 9 sind mit der Innenschale 5 der Sektionen verklebt oder - wie im Ausführungsbeispiel - an dieser durch eine Anzahl vorzugsweise in gleichmäßigen Abschnitten angeordneter Nietverbindungen 13 befestigt.3 and 4 is one of the door leaf forming Sections 4 in perspective and in one by End cap 8 shown cross section. one comparative examination of the figures shows that on the inner shell 5 of the section reinforcement profiles 9 are attached that extend the entire length of the section extend to the end caps 8 and connected to them are. In the area of the end caps there are stiffening profiles 10 driven into the insulation layer 7 of the section and with the End caps 8 connected to the cross-sectional profile of the Stiffen end caps 8. They consist in Embodiment from a hat profile, the one U-shaped cross-section and molded on the U-legs, has outwardly projecting flange surfaces. As Stiffening profiles 10 are also rectangular tube sections and similar profile body suitable. The reinforcement profiles and the stiffening profiles are in the embodiment Rivets 11 which pass through holes in the inner shell 5, connected with each other. The outer shell 6 is through a Number of rivet connections 12 to the end cap 8 and in Area of the end caps used stiffening profiles 10 connected. With one acting on the inner shell 5 The rivet connections 11, 12 are in the area of the load End cap 8 exposed to high shear forces, so that at least used in the area of the end cap 8 Fastening means 11, 12 made of a shear-resistant material, preferably tempered steel. in the Embodiment stainless steel rivets 11, 12 are used. The reinforcement profiles 9 are with the inner shell 5 of the Sections glued or - as in the embodiment - to this by a number, preferably in uniform Sections of arranged rivet connections 13 attached.

Bei einem Transport von Cargobehältern z. B. auf Straßenund Schienenfahrzeugen, kann das Torblatt 3 einer hohen, auf die Torblattinnenseite des Torblattes wirkenden Last ausgesetzt sein, wenn die Ladung infolge eines Unfalles verrutscht. Die erfindungsgemäß vorgesehenen Verstärkungsund Versteifungsprofile 9,10 verleihen den sandwichartig aufgebauten Sektionen 4 ausreichende Formstabilität und Festigkeit im Falle einer auf die Innenschale 5 wirkenden Last. Erfindungsgemäß sind die Verstärkungs- und Versteifungsprofile 9,10 dabei so aufeinander abgestimmt, dass die Dämmschicht 7 bei einer zulässigen Verformung der Innenschale 5 unter einer gleichmäßig auf die Innenschale 5 wirkenden Prüflast, die mindestens 800 kg/m2 beträgt, zwischen der sich verformenden Innenschale 5 und der dabei unter Zugspannung stehenden Außenschale 6 auf Druck beansprucht ist und Scherbeanspruchungen, die einen Riss des Hartschaumes bewirken, von der Dämmschicht 7 ferngehalten werden. Die Verformung der Innenschale 5, die sich aus einem elastisch reversiblen Anteil und einem irreversiblen Deformationsanteil zusammensetzt, wird so festgelegt, dass der nach Entlastung bleibende irreversible Deformationsanteil kleiner ist als 15 mm, und zwar gemessen in der Mitte der Sektion. Bei diesem Wert ist eine ordnungsgemäße Funktion des Sektionaltors noch problemlos gewährleistet. Die an der sichtbaren Seite der Innenschale 5 befestigten Verstärkungsprofile sollen weniger als 20 mm in dem Innenraum des Cargobehälters vorstehen. Im Ausführungsbeispiel weisen die als Hutprofil mit einem U-förmigen Querschnitt und seitlich abstehenden Flanschflächen ausgebildeten Verstärkungsprofile 9 eine Höhe von etwa 15 mm auf.When transporting cargo containers such. B. on road and rail vehicles, the door leaf 3 may be exposed to a high load acting on the inside of the door leaf if the load slips as a result of an accident. The reinforcement and stiffening profiles 9, 10 provided according to the invention give the sandwich-like sections 4 sufficient dimensional stability and strength in the event of a load acting on the inner shell 5. According to the invention, the reinforcement and stiffening profiles 9, 10 are matched to one another in such a way that the insulation layer 7 is subjected to a permissible deformation of the inner shell 5 under a test load which acts uniformly on the inner shell 5 and is at least 800 kg / m 2 between the deforming inner shell 5 and the outer shell 6, which is under tension, is subjected to pressure and shear stresses, which cause a crack in the rigid foam, are kept away from the insulation layer 7. The deformation of the inner shell 5, which is composed of an elastically reversible portion and an irreversible deformation portion, is determined so that the irreversible deformation portion remaining after relief is less than 15 mm, specifically measured in the middle of the section. With this value, proper functioning of the sectional door is still guaranteed without any problems. The reinforcement profiles attached to the visible side of the inner shell 5 should protrude less than 20 mm in the interior of the cargo container. In the exemplary embodiment, the reinforcement profiles 9, which are designed as a hat profile with a U-shaped cross section and laterally projecting flange surfaces, have a height of approximately 15 mm.

The side connected end caps are made of 1.0 mm sheet steel.

Die Sektion wurde mit der Außenschale nach unten auf zwei Stützen aufgebockt, wobei die freitragende Länge 2370 mm betrug. An der Oberseite wurden anschließend in gleichmäßiger Lastverteilung Prüflasten aufgebracht.The section was made with the outer shell down on two Jacked supports, the unsupported length 2370 mm scam. At the top were then more even Load distribution applied to test loads.

1. Versuch1st attempt

In einem Referenzversuch wurde die beschriebene Sektion ohne Versteifungs- und Verstärkungsprofile getestet. Bei einer Belastung von 420 kg wurde in der Sektionsmitte eine Durchbiegung von 40 mm gemessen. Bei einer Belastung von 480 kg ist die Sektion gebrochen. The section described was used in a reference experiment tested without stiffening and reinforcement profiles. at a load of 420 kg was in the middle of the section Deflection measured 40 mm. With a load of The section is broken 480 kg.

2. VersuchSecond attempt

An der Außenseite der Sektion wurden drei Verstärkungsprofile angebracht, die sich über die gesamte Länge der Sektion bis zu den Endkappen erstreckten und mit diesen verbunden wurden. Die Verstärkungsprofile bestanden aus 1,5 mm dickem Stahlblech und besaßen ein U-Profil mit einem 20 mm breiten Steg und 15 mm hohen Schenkeln. An das U-Profil schließen seitliche Abkantungen an, die mit der Innenschale und den Endkappen der Sektion vernietet wurden. Die in der beschriebenen Weise verstärkte Sektion konnte bis zu 940 kg belastet werden. Bei der Belastung von 940 kg wurde eine Durchbiegung in der Sektionsmitte von 58 mm gemessen. Bei 960 kg löste sich die Außenschale vom Hartschaum und kam es zu einem Bruch der Sektion.On the outside of the section were three reinforcement profiles attached, which extends over the entire length of the Section extended to and with the end caps were connected. The reinforcement profiles consisted of 1.5 mm thick steel sheet and had a U-profile with a 20 mm wide bridge and 15 mm high legs. To the U-profile connect side bends with the inner shell and riveted to the end caps of the section. The in the described way reinforced section could be up to 940 kg be charged. At a load of 940 kg, one was Deflection measured in the center of the section of 58 mm. at 960 kg the outer shell detached from the hard foam and it came to a break in the section.

3. Versuch3. Attempt

Eine entsprechend dem 2. Versuch mit drei innenseitigen Verstärkungsprofilen ausgerüstete Sektion wurde zusätzlich mit Versteifungsprofilen verstärkt, die zur Erhöhung der Formstabilität der Endkappen in die Endkappen eingesetzt wurden. Die Versteifungsprofile waren als Hutprofile ausgebildet und mit Nieten aus Edelstahl mit der Außenschale sowie den an der Innenschale angebrachten Verstärkungsprofilen verbunden. Die erfindungsgemäß ausgebildete Sektion hielt einer Belastung von 1080 kg bei einer in der Sektionsmitte gemessenen Durchbiegung von 69 mm stand. Nach Entlastung der Sektion wurde ein irreversibler Deformationsanteil von 7 mm gemessen. One corresponding to the 2nd attempt with three inside Section equipped with reinforcement profiles was added reinforced with stiffening profiles that increase the Dimensional stability of the end caps inserted into the end caps were. The stiffening profiles were designed as hat profiles and with stainless steel rivets with the outer shell as well as the reinforcement profiles attached to the inner shell connected. The section designed according to the invention held a load of 1080 kg at one in the Section deflection of 69 mm measured in the middle. To Relief of the section became an irreversible part of the deformation measured of 7 mm.
