The present invention relates to a bottom plate structure of a refrigeration truck loading box, more specifically, to facilitate the joining of the assembly plate in the process of assembling the bottom plate, such as a tower car or a refrigeration vehicle refrigeration vehicle made of various sizes, to prevent slipping during operation It relates to the bottom plate structure of the refrigeration truck loading box to be.

In general, the top vehicle is formed with a loading box so that the loading box is boxed so that the load can be protected from snow or rain without falling. In the case of a refrigerated truck or a refrigerated truck, it is intended to transport cargoes that may be deteriorated, such as dairy products or frozen foods.

As shown in FIG. 8, the above-mentioned loading box of the refrigeration tower vehicle has a rectangular box shape, and is mounted on the upper side of the chassis located behind the cabin 2 of the vehicle. A door (not shown) for loading or unloading cargo into the loading box 1 is formed on the back or side of the loading box 1.

In addition, the bottom plate 10 of the loading box 1 has a plurality of convex portions 12 arranged parallel to each other at predetermined intervals and bent upwardly convex, with a strength capable of sufficiently supporting the cargo loaded in the loading box 1. .

However, since the loading box 1 has various sizes depending on the size of the loaded truck, the bottom plate 10 for the loading box is also manufactured in various sizes. However, it is very disadvantageous in terms of productivity and economy because a large number of manufacturing facilities are required to provide all of the bottom plates corresponding to the various sizes of the loading boxes 1.

Therefore, the bottom plate 10 corresponding to the size of the stacking box 1 is completed by manufacturing the bottom plate 10 standardized to a substantially constant size and joining two or more bottom plates 10 to each other.

However, the conventional bottom plate bonding structure as described above has the following disadvantages.

First, the conventional bottom plate joining structure as described above has a disadvantage that it is not aesthetically good because the welded portion is exposed to the outside. In addition, since the flanges of the two bottom plates are joined using a welding rod, the joining degree is weak. Therefore, there is a disadvantage in that the joints of the flanges are broken due to the load and thermal fatigue of the cargoes, and leakage occurs. If the flanges of the bottom plate are welded at a high temperature without using a welding rod, holes are formed in the welded portion due to heat deformation of the flanges, and there is a disadvantage that a risk of leakage occurs from the beginning.

In addition, the bottom surface of the stacker of the conventional freezer tower has a problem that the convex portion is formed in a flat, and the convex portion is formed in the frost for the refrigeration facility, the safety accident that the worker slips during the operation.

Therefore, the present invention has been made in order to solve the above problems, in order to facilitate the bonding of the assembly plate in the process of assembling the bottom plate, such as a tower car or a refrigeration car refrigerated car made of various sizes, the refrigeration to prevent slipping It is an object to provide a bottom plate structure of the tower stacker.
