Definitions

  • the invention relates to a double-walled refrigerated container with foamed-in insulation, with a double-walled base with foamed-in insulation, the upper bottom wall of which consists of a base plate with longitudinal, cross-sectionally T-shaped supports, the upper flanges of which are arranged with longitudinal gaps and form a loading area.
  • the base plates with the T-shaped supports are generally used as extruded profiles, e.g. made of aluminum, in one piece, and the individual profiles are welded to a waterproof floor.
  • the longitudinal chambers between the webs of the T-shaped supports enable the unhindered return flow of the cooling air under the load to the cooling unit when the vehicle is loaded.
  • the object of the invention is seen in improving the base plate so that the floor can also withstand high impact-like, local loads.
  • the base plate is corrugated, the wave crests are at the location of the T-shaped supports and that the base plate is clawed by anchoring with the insulation.
  • the waveform of the base plate allows the vertical leg of the T-shaped supports to be made very short while maintaining sufficiently large channels for the air flow. This significantly increases the resistance to one-sided loads on the outer edges of the flanges.
  • the wave-shaped design of the base plate, with the wave crest facing the T-shaped support stiffens the base plate at the point of introduction of the force and thus even with a concentrated local load, an even introduction into the insulation, which increases the risk of critical overloading of the connection point between the base plate and the insulation is avoided.
  • connection area due to the waveform of the base plate and the resulting positive fit with regard to shear stress in the transverse direction has a positive effect on the security of the bond.
  • the anchors support this effect and are also effective against lifting the base plate vertically from the insulation. Due to the laterally beveled surfaces of the base plate, which form the channels, the advantage is additionally achieved that during cleaning measures, the cleaning liquid with the dirt residues is directed into the clearly visible central area of the channel, the outflow rate even with small amounts of liquid due to the narrowing of the channel bed remains high at the bottom and dirt residues are effectively taken away. This is a significant improvement over the known floors with the dreaded corner of dirt right at the foot of the T-shaped supports.
  • the invention can be advantageously configured as follows.
  • a favorable form of the wave crests in cross-section is that of an isosceles triangle, at the apex of which the T-shaped support stands.
  • the same legs expediently enclose an approximately right angle. Due to the oblique transitions of the angled legs into the lower surface of the base plate, the buckling height of the web of the T-shaped support is reduced, and a higher buckling stiffness can be achieved with a reduced use of material compared to the flat base plate according to the prior art.
  • FIG. 1 An exemplary embodiment of the invention is explained below with reference to a drawing.
  • the drawing shows the lower left corner area of a refrigerated container in cross section.
  • the double-walled refrigerated container has foamed-in insulation 1. Its bottom has a base plate 2 with longitudinal supports T-shaped in cross section 3, the upper flanges 4 of which form the loading area with longitudinal spaces 5.
  • the base plate 2 is designed corrugated, the waves being isosceles triangles with an approximately right upper angle on which the T-shaped supports 3 stand.
  • 2 anchors 7 extend into the insulation, which are designed as longitudinal, T-shaped webs.
  • the complete, corrugated base plate 2 with the supports 3 with flanges 4 and the anchors 7 has been produced as an extruded profile, the length at least corresponding to the container length and the width chosen as large as possible within the scope of the production possibility.
  • the extruded base plates have been welded together with weld seams 8.
