Das dargestellte Ausführungsbeispiel eines temperaturgeführten Isolier- und Kühltransportbehälters 1 (Fig. 1) weist einen quaderförmigen Behälterkörper 23 auf, der aus Raumbegrenzungselementen besteht. Die Raumbegrenzungselemente (Fig. 2), welche den Behälterinnenraum umfassen, sind ein Dachelement 2, ein Bodenelement 3 und Seitenwände 4 (nur eine in Fig. 2 dargestellt) , sowie eine Endwand (Frontwand 22). Jedes der Raumbegrenzunselemente 2 bis 4 besitzt einen Wandkern aus Hartschaumstoff, insbesondere Polyurethanschaum, welcher von Randholmen umfaßt ist. Die Randholme können ganz oder teilweise aus glasfaserverstärkten Kunststoffen bestehen. Die Randholme können auch als Hohlprofile (Umhüllung 28) aus faserverstärktem Kunststoff mit einem Holmkern 27 ausgebildet sein. Die Randholme besitzen bevorzugt einen rechteckigen Querschnitt und werden als Pfosten oder Balken in herkömmlicher Weise hergestellt. Es kommen glasfaserverstärkte Kunststoffe (GFK) und/oder kohlenstofffaserverstärkte Kunststoffe (CFK) zum Einsatz. Auch faserverstärkte Kunststoffe mit speziellen Mischgeweben aus CFK und GFK können zur Anwendung kommen. Die einzelnen Randholme werden zu einem rechteckigen Rahmen, insbesondere durch Kleben oder Nieten, zusammengefügt. Die Hartschaumkerne der Randholme können in bekannter Weise in einer entsprechenden Gießform oder in der schon fertigen faserverstärkten Kunststoffumhüllung 28 hergestellt werden. Die fertigen, zu einem Rahmen miteinander verbundenen Randholme aus dem faserverstärkten Kunststoff werden in eine Form eingebracht, in welcher beispielsweise durch bekannte Reaktionsgußtechnik der Wandkern aus Hartschaumstoff gebildet wird. Der jeweilige Wandkern aus Hartschaumstoff und der aus den Randholmen bestehende den Wandkern umgebende Rahmen bildet die mittlere Lage eines Sandwich-Aufbaus des jeweiligen Raumbegrenzungselements. Auf diese mittlere Lage werden beidseitig Deckschichten aufgebracht. Auf der einen Seite wird hierdurch eine im Behälterinnern liegende Innenhaut 29 und auf der anderen Seite eine auf der Behälteraußenseite liegende Außenhaut 30 gebildet. Die Innenhaut 29 und die Außenhaut 30 bestehen aus faserverstärktem Kunststoff. Die die Seitenwände 4 und die Frontwand 22 bildenden Raumbegrenzungselemente besitzen bevorzugt einen dikkensymmetrischen Sandwich-Aufbau.The illustrated embodiment of a temperature-controlled insulating and refrigerated transport container 1 (FIG. 1) has a cuboid-shaped container body 23 which is made of Space limitation elements exist. The space limitation elements (Fig. 2), which the container interior include a roof element 2, a bottom element 3 and Side walls 4 (only one shown in Fig. 2) and an end wall (front wall 22). Each of the room boundary elements 2 to 4 has a wall core made of rigid foam, in particular polyurethane foam, which is surrounded by side rails. The Edge bars can be made entirely or partially of glass fiber reinforced plastics. The side rails can also be made of fiber-reinforced hollow sections (covering 28) Plastic be formed with a spar core 27. The side rails preferably have a rectangular cross section and are used as posts or beams in conventional Manufactured way. There are glass fiber reinforced plastics (GRP) and / or carbon fiber reinforced Plastics (CFRP) are used. Also fiber reinforced plastics special blended fabrics made of CFRP and GFRP can be used. The single ones Edge bars become a rectangular frame, especially by gluing or rivets, put together. The hard foam cores of the side rails can be known Way in an appropriate mold or in the already finished fiber-reinforced Plastic sheath 28 are made. The finished, to a frame with each other connected side rails made of fiber-reinforced plastic are placed in a mold, in which, for example, by known reaction casting technology of the wall core is formed from rigid foam. The respective wall core made of rigid foam and the frame, which consists of the side rails and surrounds the wall core, forms the middle layer of a sandwich construction of the respective space delimitation element. On this middle layer, top layers are applied on both sides. On the one hand this creates an inner skin 29 inside the container and on the other side an outer skin 30 is formed on the outside of the container. The inner skin 29 and the outer skin 30 consist of fiber-reinforced plastic. The side walls 4 and The space boundary elements forming the front wall 22 preferably have a thickness-symmetrical Sandwich structure.

Auf diese Weise werden die einzelnen Raumbegrenzungselemente, welche den quaderförmigen Behälterkörper 23 bilden, hergestellt, wobei während des Reaktionsgusses des Wandkernes aus Hartschaumstoff eine feste Verbindung mit dem Kunststoff der Randholme besteht.In this way, the individual space delimiting elements, which are cuboid Form container body 23, produced, wherein during the reaction casting of the Wall core made of rigid foam a firm connection with the plastic of the side rails consists.

Wie aus den Figuren 1 und 2 zu ersehen ist, besteht das Dachelement 2 aus dem Wandkern 13 und den Randholmen 5 und 6, welche zu einem den Wandkern 13 umfassenden Rahmen miteinander verbunden sind. Die beiden Seitenwände 4 werden von den Wandkernen 15 und den Randholmen 9 und 10 jeweils gebildet. Die Randholme 9 und 10 sind ebenfalls zu einem, den jeweiligen Wandkern 15 umfassenden Rahmen miteinander verbunden. Das Bodenelement 3 besteht aus einem Wandkern 14 und den den Wandkern rahmenförmig umfassenden Randholmen 7 und 8. Die Frontwand 22 wird von einem Wandkern 16 und den den Wandkern 16 rahmenförmig umfassenden Randholmen 11 und 12 gebildet. Gegebenenfalls können zur weiteren Vereinfachung die Randholme 11 und 12 wegfallen und der mit der Außen- und innenhaut belegte Wandkern 16 direkt in die vorderen Randholme 6, 7 und 10, welche den Rahmen für den Wandkern 16 bilden, eingesetzt sein.As can be seen from Figures 1 and 2, the roof element 2 consists of the Wall core 13 and the side rails 5 and 6, which form a wall core 13 Frames are interconnected. The two side walls 4 are of the wall cores 15 and the side rails 9 and 10 each formed. The edge bars 9 and 10 are also part of a frame comprising the respective wall core 15 connected with each other. The floor element 3 consists of a wall core 14 and the the wall core frame-shaped edge spars 7 and 8. The front wall 22nd is of a wall core 16 and the wall core 16 enclosing a frame Edge bars 11 and 12 formed. If necessary, for further simplification the side rails 11 and 12 are removed and the one covered with the outer and inner skin Wall core 16 directly in the front side rails 6, 7 and 10, which the frame for form the wall core 16, be used.

Die Raumbegrenzungselemente 2 bis 4 und 22 werden zur Bildung des quaderförmigen Behälterkörpers 23 im Bereich ihrer Randholme, insbesondere durch Verkleben, fest miteinander verbunden. Entlang der Innenkanten und Außenkanten des Behälters 1 können zur großflächigen Verbindung längsverlaufende Kantenprofile 19 und 20 vorgesehen sein. Dadurch werden entlang den jeweiligen Holmen feste flächige Verbindungen gebildet, die ein starres und steifes aus den Holmen bestehendes Gerüst bilden. Hierbei wirken die Randholme 5 und 9, entlang welcher die Seitenwände 4 mit dem Dachelement 2 verbunden sind, und die Randholme 8 und 9, entlang welcher das Bodenelement 3 mit den Seitenwänden 5 verbunden ist, als Längsträger. Hierbei können zusätzlich Längsträger 25, welche einen Aufbau wie die Randholme haben, vorgesehen sein (Fig. 4). Die Längsträger 25 können nach innen vorspringend ausgebildet sein, so daß sie an ihrer Oberseite eine Auflage- und Verbindungsfläche im Bereich des jeweiligen Randholmes 8 des Bodenelements 3 bilden. Der jeweilige Längsträger, welcher an seinen Enden in Ecken von endseitigen Verstärkungsrahmen 17, 18, gelagert ist, besitzt einen Hartschaumkern 34 und eine den Hartschaumkern in Form eines Hohlprofils umgebende Umhüllung 35 aus faserverstärktem Kunststoff. Gegebenenfalls können bei den beiden Seitenwänden 4 die unteren Randholme 9 in Wegfall kommen, wobei durch die Längsträger 25 zusammen mit den übrigen Randholmen 9 und 10 die Rahmenfunktion am jeweiligen die Seitenwand 4 bildenden Raumbegrenzugnselement erfüllt wird. Der Wandkern 15 der jeweiligen Seitenwand 4 erstreckt sich dann bis zum Längsträger 25 zwischen der Innenhaut 29 und der Außenhaut 30.The space limitation elements 2 to 4 and 22 are used to form the cuboid Container body 23 in the region of their side rails, in particular by gluing connected with each other. Along the inner edges and outer edges of the container 1 can be provided for large-area connection longitudinal edge profiles 19 and 20 his. As a result, fixed flat connections along the respective spars formed, which form a rigid and rigid framework consisting of the spars. in this connection act the side rails 5 and 9, along which the side walls 4 with the roof element 2 are connected, and the edge bars 8 and 9, along which the floor element 3 is connected to the side walls 5, as a longitudinal beam. Here you can additionally Side members 25, which have a structure like the side rails, can be provided (Fig. 4). The longitudinal members 25 can be formed projecting inwards so that they are on its top side a support and connecting surface in the area of the respective edge beam 8 of the bottom element 3 form. The respective side member, which on its Ends in corners of end reinforcement frames 17, 18, is mounted, has a hard foam core 34 and one Rigid foam core in the form of a hollow profile surrounding casing 35 made of fiber-reinforced Plastic. If necessary, the lower side of the two side walls 4 Edge spars 9 are eliminated, with the longitudinal members 25 together with the remaining side rails 9 and 10 form the frame function on the respective side wall 4 Room boundary element is met. The wall core 15 of the respective side wall 4 then extends to the longitudinal member 25 between the inner skin 29 and the Outer skin 30.

Die Randholme 6 des Dachelements 2 und die Randholme 7 des Bodenelements 3, welche quer verlaufen, haben in dem quaderförmigen Aufbau des Behälterkörpers 23 Querträgerfunktion. Diese Querträgerfunktion wird noch unterstützt durch die Randholme 11 der Endwand (Frontwand) 22. Durch den von den Randholmen 11 und 12 geschaffenen Rahmen der Endwand 22 wird ferner die dreidimensionale Steifigkeit des quaderförmigen Aufbaus des Behälterkörpers 23 unterstützt.The edge bars 6 of the roof element 2 and the edge bars 7 of the floor element 3, which run transversely have in the cuboid structure of the container body 23 Crossbeam function. This cross beam function is further supported by the side rails 11 of the end wall (front wall) 22. By the created by the side rails 11 and 12 Frame of the end wall 22 is also the three-dimensional stiffness of the cuboid structure of the container body 23 supports.

Zusätzlich können an den beiden Enden des Behälterkörpers 23 die Verstärkungsrahmen 17 und 18 vorgesehen sein. Die Verstärkungsrahmen können aus Stahl oder faserverstärktem Kunststoff mit Ausnahme von Corner Fittings 24 in den jeweiligen Rahmenecken bestehen. Die Corner Fittings 24 bestehen aus Stahl und sind entsprechend den jeweiligen Vorschriften für Isolier- und Kühlbehälter, insbesondere Container, ausgebildet. Die beiden Verstärkungsrahmen 17 und 18 sind separat an den beiden Enden des Behälterkörpers 23 vorgesehen. Aufgrund der Steifigkeit, welche der Behälterkörper 23 durch die flächig (insbesondere durch die zusätzlichen Kantenprofile 19 und 20) miteinander verbundenen Raumbegrenzungselemente hat, ist es nicht erforderlich, daß die beiden Verstärkungsrahmen durch zusätzliche, entlang der Behälterkanten vorgesehene Verbindungsprofile miteinander verbunden sind. Die einzelnen Raumbegrenzungselemente 2, 3, 4 und 22 besitzen jedes für sich selbsttragende Eigenschaft, und durch ihre feste flächige Verbindung entlang der Randholme wird eine dreidimensionale Steifigkeit des Behälterkörpers erreicht. Da die Wandbegrenzungselemente in ihrem Sandwich-Aufbau mit den relativ dünnen Innen- und Außenhäuten 29, 30 ausclehnungsmäßig im wesentlichen von den großflächigen Wandkernen 13, 14, 15 und 16 aus einem durchgehenden Hartschaumkörper, insbesondere Polyurethanschaum, gebildet sind, ergibt sich ein äußerst leichter Aufbau des Behälterkörpers 23. Die notwendige Steifigkeit wird von den die Wandkerne rahmenförmig umfassenden Randholmen in Zusammenwirkung mit den Innen- und Außenhäuten 29, 30 gewährleistet. Dadurch wird ferner erreicht, daß die Dimensionierung der Seitenwände 4, des Dachelementes 2 und des Bodenelernentes 3 optimal gering gehalten werden können bei der erforderlichen Wärmeisolation.In addition, the reinforcing frames can be provided at both ends of the container body 23 17 and 18 may be provided. The reinforcement frame can be made of steel or fiber reinforced Plastic with the exception of corner fittings 24 in the respective frame corners consist. The corner fittings 24 are made of steel and are in accordance with the respective regulations for insulating and cooling containers, in particular containers. The two reinforcement frames 17 and 18 are separate at the two ends of the Container body 23 is provided. Due to the rigidity which the container body 23 through the flat (in particular through the additional edge profiles 19 and 20) with each other connected space limitation elements, it is not necessary that the two reinforcement frames by additional, provided along the container edges Connection profiles are interconnected. The individual space limitation elements 2, 3, 4 and 22 each have self-supporting properties, and by their own fixed flat connection along the side rails becomes a three-dimensional rigidity of the container body reached. Because the wall boundary elements in their sandwich construction with the relatively thin inner and outer skins 29, 30 essentially of the large wall cores 13, 14, 15 and 16 from a continuous Rigid foam body, in particular polyurethane foam, are formed an extremely light structure of the container body 23. The necessary rigidity is from in cooperation with the frame spars surrounding the wall cores the inner and outer skins 29, 30 guaranteed. This also ensures that the Dimensioning of the side walls 4, the roof element 2 and the floor element 3 can be kept optimally low with the required thermal insulation.

Die Verbindung der Kunststoffkonstruktion des Behälterkörpers 23 mit den beiden Verstärkungsrahmen 17 und 18 kann zusätzlich mit Hilfe von Kleb-Wings verstärkt sein. Diese Kleb-Wings können als beispielsweise 2 mm dicke innenliegende Stahlbleche ausgebildet sein. Hierdurch werden die Übergänge zwischen der Kunststoffkonstruktion des Behälterkörpers 23 und den beiden Verstärkungsrahmen 17 und 18 zusätzlich verstärkt.The connection of the plastic construction of the container body 23 with the two reinforcement frames 17 and 18 can also be reinforced with the help of adhesive wings. These adhesive wings can be, for example, 2 mm thick internal steel sheets be trained. This will make the transitions between the plastic construction of the container body 23 and the two reinforcement frames 17 and 18 additionally reinforced.

In bekannter Weise können am Verstärkungsrahmen 17 nicht näher dargestellte Türflügel zum Öffnen und Verschließen des Behälters 1 an schematisch dargestellten, z.B. als Scharniere ausgebildeten Befestigungselementen 26 schwenkbar befestigt sein.In a known manner, door leaves, not shown, can be provided on the reinforcement frame 17 for opening and closing the container 1 on schematically illustrated, e.g. as Hinges trained fasteners 26 be pivotally attached.

Der Boden des Behälters 1 wird von dem Raumbegrenzungselement 3 und an seiner Unterseite befestigten Querholmen 31 gebildet. Die Querholme 31 sind mittels einer Kunststoffhaut 36 an der Unterseite des Bodens 3 befestigt. Die Kunststoffhaut 36 besteht aus faserverstärktem Kunststoff. Die sich im wesentlichen über die gesamte Breite des Bodens hin erstreckenden Querholme 31 besitzen bevorzugt einen trapezförmigen Querschnitt. Wie die Randholme und die Längsträger 25 besitzen die Querholme 31 einen Holmkern 32 aus Hartschaumstoff, insbesondere Polyurethan, und eine Umhüllung 33 aus faserverstärktem Kunststoff. An der Oberseite des Bodens 3 ist eine gegebenenfalls dampfdicht verschweißte Gräting 21, welche mit dem Boden verklebt ist, vorgesehen. Die Gräting 21 kann aus T-förmigen längsverlaufenden Profilen, beispielsweise aus Aluminium bestehen. Sie kann jedoch auch in der Weise ausgebildet sein, wie es in der deutschen Patentanmeldung 197 01 171.3 beschrieben ist. Die Kunststoffhaut 36, mit welcher die Querträger 31 an der Unterseite des Bodens befestigt sind, kann die Außenhaut des Bodens 3 bilden.The bottom of the container 1 is from the space-limiting element 3 and on it Bottom attached cross bars 31 formed. The cross bars 31 are by means of a Plastic skin 36 attached to the bottom of the bottom 3. The plastic skin 36 is made made of fiber-reinforced plastic.
