Refrigerating container comprising a steel frame with upper (1) and lower (2) longitudinal bearers, lower cross-members, with corner posts, with an insulation (4), with an inner cladding comprising inner wall panels (5), and with indented outer wall panels (3) which are connected at the upper and lower edges to the longitudinal bearers (1, 2) and at the side edges to the corner posts, characterised in that indentation of the outer wall panels (3) extends in the vertical direction, and that indentation ends short of the edge of the outer wall panels (3) in a manner known per se, and that the connection of the indented outer wall panels (3) to the upper (1) and lower (2) longitudinal bearers and to the corner posts is formed as an encircling weld seam (8).

Description

Die Erfindung betrifft einen Kühlcontainer aus einem Stahlgestell mit oberen und unteren Längs- und unteren Querträgern, mit gesickten Außenwandplatten, einer Isolierung und einer Innenbeplankung aus Platten. Bei bekannten, derartigen Containern ist die Sickung als waagerechte, durchlaufende Sickung der Außenwandplatten ausgeführt, um deren Beulfestigkeit zu erhöhen. Die Außenwände sind im allgemeinen mit den Längsträgern vernietet. Es sind auch Container bekannt, bei denen die Außenwände glatt ausgeführt sind. Bei beiden Arten von Containern wird die Seitenwandbelastung von einem zwischen den Innen- und den Außenwandplatten angeordneten Traggerüst, das einen Teil des Raums für die Isolierung wegnimmt, auf die Träger übertragen. Diese Bauart ist aufwendig und verschlechtert den Isolierwert des Containers erheblich.The invention relates to a refrigerated container made of a steel frame with upper and lower longitudinal and lower cross members, with corrugated outer wall panels, insulation and an inner paneling made of panels. In known containers of this type, the beading is designed as a horizontal, continuous beading of the outer wall panels in order to increase their resistance to buckling. The outer walls are generally riveted to the side members. Containers are also known in which the outer walls are smooth. In both types of containers, the sidewall load is transferred to the beams from a support structure located between the inner and outer wall panels, which takes up part of the space for insulation. This design is complex and significantly deteriorates the insulation value of the container.

Ausgehend von diesem Stand der Technik wird die Aufgabe der Erfindung darin gesehen, einen Kühlcontainer zu entwickeln, bei dem die Seitenwandbelastung unter Beibehaltung einer im wesentlichen gleichmäßig dicken Isolierschicht zwischen Innen- und Außenwand und ohne zusätzliche Innenkonstruktionen sicher in die unteren Träger eingeleitet werden.Based on this prior art, the object of the invention is seen in developing a refrigerated container in which the side wall load is safely introduced into the lower supports while maintaining an essentially uniformly thick insulating layer between the inner and outer walls and without additional inner structures.

Erfindungsgemäß wird diese Aufgabe bei einem Kühlcontainer der eingangs genannten Gattung dadurch gelöst, daß die Außenwandplatten in senkrechter Richtung gesickt sind, daß sie am oberen und am unteren Rand mit den Längsträgern und den Pfosten verbunden sind und daß die Sickung vor der Verbindungsstelle der Platten mit den Längsträgern endet. Die so erreichte Aussteifung der gesickten Außenwand ermöglicht zusammen mit dem Auslaufen der Sicken vor der Verbindungsstelle und der Verbindung mit den oberen und unteren Längsträgern, die Kräfte ohne Zuhilfenahme von weiteren Abstützelementen zu übertragen. Die Isolierschicht hat dabei, abgesehen von einer geringfügigen Minderung der Dicke an den Sickenstellen, im wesentlichen überall eine gleichmäßige Stärke und damit gute Isolierwerte. Die glatte, lineare Verbindung des ebenen Bleches mit den oberen und unteren Trägern und den Eckpfosten - nicht eines trapezförmigen Blechquerschnittes mit den Pfosten wie bei den bekannten Containern - ermöglicht eine sehr feste, gegen Undichtwerden sichere Verbindung und ist reparaturfreundlich. Der erfindungsgemäße Container ist besonders auch für den Gütertransport mit verderblichen Waren geeignet, da bei einer Stoßbelastung auf die Außenwand in der Regel lediglich das Blech verbeult wird und die Wärmedämmeigenschaften erhalten bleiben. Er ist insoweit auch den bekannten Kühlcontainern mit GFK-Außenwänden überlegen, bei denen eine stoßweise Beananspruchung zur teilweisen Zerstörung der Außenwand, Eindringen von Feuchtigkeit in die Isolierung und dadurch zum unzulässigen Temperaturanstieg im Container führen kann.According to the invention this object is achieved in a refrigerated container of the type mentioned in that the outer wall panels are crimped in a vertical direction in that they are at the top and bottom the side members and the posts are connected and that the beading ends before the junction of the plates with the side members. The reinforcement of the corrugated outer wall achieved in this way, together with the running out of the corrugations in front of the connection point and the connection with the upper and lower longitudinal members, enables the forces to be transmitted without the aid of further support elements. The insulation layer has, apart from a slight reduction in the thickness at the beads, essentially a uniform thickness everywhere and thus good insulation values. The smooth, linear connection of the flat sheet with the upper and lower beams and the corner posts - not a trapezoidal sheet cross-section with the posts as with the known containers - enables a very firm connection that is secure against leakage and is easy to repair. The container according to the invention is also particularly suitable for the transportation of goods with perishable goods, since in the event of an impact load on the outer wall, as a rule only the sheet metal is dented and the thermal insulation properties are retained. In this respect, it is also superior to the known refrigerated containers with GRP outer walls, in which intermittent stress can lead to partial destruction of the outer wall, penetration of moisture into the insulation and thus to an inadmissible temperature rise in the container.

Im einzelnen kann die Erfindung wie folgt vorteilhaft ausgestaltet sein.In particular, the invention can be advantageously configured as follows.

Dadurch, daß die Außenwandplatten und die Innenwandplatten mit der dazwischenliegenden Isolierung fest verbunden sind, entsteht eine besonders feste, zur Übertragung von Lasten geeignete Ausbildung als Sandwich. Eine derartige Verbindung kann z.B. durch Ausschäumen erzielt werden.Characterized in that the outer wall panels and the inner wall panels are firmly connected to the insulation in between, a particularly strong, suitable for the transmission of loads training as a sandwich. Such a connection can e.g. can be achieved by foaming.

Eine völlig gleichmäßige Dicke der Isolierschicht kann dadurch erreicht werden, daß die Außenwandplatten und die Innenwandplatten an einander gegenüberliegenden Stellen in gleicher Richtung gesickt sind. Zweckmäßigerweise wird man dabei die Sicken gleich ausführen, so daß ein paralleler Verlauf der Blechflächen erzielt wird. Das ist auch vom Standpunkt der Produktionsvereinfachung vorteilhaft. Die zusätzliche Sickung der Innenwandplatten führt außerdem zu einer Erhöhung der Stabilität und damit der Tragfähigkeit.A completely uniform thickness of the insulating layer can be achieved in that the outer wall panels and the inner wall panels are corrugated at opposite locations in the same direction. The beads are expediently designed to be the same, so that a parallel course of the sheet metal surfaces is achieved. This is also advantageous from the standpoint of simplifying production. The additional beading of the inner wall panels also leads to an increase in stability and thus the load-bearing capacity.

Dadurch, daß die gesickten Außenwandplatten umlaufend mit den oberen und unteren Trägern und den Eckpfosten verschweißt sind, entsteht eine völlig dichte, sehr feste Außenschale.Because the corrugated outer wall panels are welded all around to the upper and lower beams and the corner posts, a completely sealed, very strong outer shell is created.

In einer anderen Ausführungsart sind die gesickten Außenwandplatten mit den oberen und unteren Trägern und den Eckpfosten vernietet.In another embodiment, the corrugated outer wall panels are riveted to the upper and lower beams and the corner posts.

Im folgenden wird anhand einer Zeichnung ein Ausführungsbeispiel der Erfindung erläutert. Es zeigen im einzelnen

  • Fig. 1 einen senkrechten Schnitt durch das Dach, eine Seitenwand und des Bodens eines Kühlcontainers,
  • Fig. 2 einen dazu senkrechten Schnitt entsprechend der in Fig. 1 mit A A bezeichneten Schnittebene,
  • Fig. 3 einen Schnitt durch den Boden, eine Seitenwand und den Boden eines Kühlcontainers in einer anderen Ausführungsart,
  • Fig. 4 einen dazu senkrechten Schnitt gemäß der in Fig. 3 mit A A bezeichneten Schnittlinie.
An exemplary embodiment of the invention is explained below with reference to a drawing. It show in detail
  • 1 is a vertical section through the roof, a side wall and the bottom of a refrigerated container,
  • 2 shows a section perpendicular to this, corresponding to the section plane designated AA in FIG. 1,
  • 3 shows a section through the bottom, a side wall and the bottom of a refrigerated container in another embodiment,
  • Fig. 4 is a section perpendicular thereto according to the section line designated AA in Fig. 3.

Der Kühlcontainer besteht aus einem Stahlgestell mit oberen 1 und unteren 2 Längsträgern und mit nicht dargestellten Eckträgern und Eckpfosten und mit gesickten Außenwandplatten 3. Die Sickung der Außenwandplatten verläuft in senkrechter Richtung und endet vor der Verbindungsstelle der Platten mit den Längsträgern 1, 2. Die Außenwandplatten 3 und die Innenwandplatten 5 sind mit der Isolierung 4 fest verbunden und bilden so ein tragfähiges Sandwichelement. Die Sicken 6 in der Außenwandplatte und 7 in der Innenwandplatte liegen einander gegenüber und sind in der gleichen Richtung ausgeführt, so daß die Isolierschicht im Sickenbereich genauso dick ist wie im nicht gesickten Bereich. Der gegenseitige Abstand je zweier Sicken 6,6 bzw. 7,7 (Figuren 2 und 4) ist variabel je nach Blechdicke und Qualität, im speziellen Beispiel beträgt er rund 200 mm. Die Verbindung der Platten am oberen und am unteren Rand mit den Längsträgern erfolgt entsprechend Fig. 1 durch Verschweißung 8,9. Auch an den nicht dargestellten Pfosten Ist der glatte, nicht gesickte, senkrechte Rand der Außenwandplatte 3 verschweißt, so daß ein geschlossener Rahmen mit einem fest damit verbundenen, stabilen Füllblech entsteht. Nach Fig. 3 ist die Verbindung mit den oberen Trägern 1 und den unteren Trägern 2 durch Nieten 10,11 verwirklicht und ebenso die nicht dargestellte Verbindung mit den Eckpfosten.The refrigerated container consists of a steel frame with upper 1 and lower 2 longitudinal beams and with corner beams and corner posts, not shown, and with corrugated outer wall panels 3. The beading of the outer wall panels runs in a vertical direction and ends before the junction of the panels with the longitudinal members 1, 2. The outer wall panels 3 and the inner wall panels 5 are firmly connected to the insulation 4 and thus form a load-bearing sandwich element. The beads 6 in the outer wall panel and 7 in the inner wall panel face each other and are designed in the same direction, so that the insulating layer in the bead area is as thick as in the non-beaded area. The mutual distance between two beads 6.6 and 7.7 (Figures 2 and 4) is variable depending on the sheet thickness and quality, in the special example it is around 200 mm. The connection of the panels at the top and bottom with the side members is carried out according to FIG. 1 by welding 8.9. Also on the post, not shown, the smooth, not corrugated, vertical edge of the outer wall plate 3 is welded, so that a closed frame with a firmly connected, stable filler plate is formed. According to Fig. 3, the connection to the upper beams 1 and the lower beams 2 is realized by rivets 10, 11 and also the connection, not shown, to the corner posts.
