Container for cold storage

Abstract

The invention relates to a refrigerated container. The soleplate of the refrigerated container comprises a floor arranged in the container body, an assistant corrugated floor arranged outside the container body, and a foaming material layer which is filled between the floor and the assistant floor; the assistant floor is connected with a bottom side beam and comprises a plurality of peaks and troughs with the same shape and arranged at intervals, and the part between the peak and the trough is an wave inclined edge. The refrigerated container is characterized in that the included angle between the wave inclined edge and the horizontal direction is less than 45 degrees. Compared with the prior art, the refrigerated container has the advantages of high welding quality, convenient painting, low cost, high production efficiency and good rigidness, etc.

Description

technical field [0001] This invention relates to a container and more particularly to an improved floor for refrigerated containers. Background technique [0002] The bottom plate of the existing refrigerated container is generally composed of the upper T floor and the lower sub-floor filled with foam material; among them, the corrugated sub-floor structure is widely used because of its good air leakage resistance and light weight. The sub-floor is generally formed by overlapping or splicing (welding or bonding) multiple corrugated sub-floors to form a whole sub-floor. Such as figure 1 with figure 2 As shown, the entire auxiliary floor 1 is welded on the bottom side beam 2 . Place the T floor 3 on one side of the auxiliary floor, and leave a certain distance between the two to fill the heat-insulating foam 4 . Since each corrugated sub-floor is welded or bonded to form the entire sub-floor, the sub-floor 1 and the bottom side beam 2 are welded together, so the air leaka...

AI Technical Summary

Problems solved by technology

[0003] (1) There are many pressing and assembling processes, and the efficiency is low;

[0004] (2) The welding with the bottom side beam is all used for manual welding, which has low welding efficiency and poor forming;

[0005] (3) The trough foam material does not have a heat insulation effect;

[0006] (4) The paint construction is difficult, resulting in a huge difference in the thickness of the paint film between the peak and the trough, and the waste is serious
