Description

{FLOOR BOARD FOR SPECIAL VEHICLE CARGO BOX}

[0001] The present invention relates to a bottom plate for a specially equipped truck, and more particularly to a bottom plate for a specially equipped truck, which comprises a plurality of support projections formed in the longitudinal direction in a "T & And which can prevent the wheels of the hand pallet from being caught by the bottom plate.

In general, a specially equipped truck is boxed so that the load can be protected from snow or rain without dropping the load. In the case of refrigerated specially equipped vehicles or refrigerated specially equipped vehicles, such as milk products or frozen foods, there are refrigeration facilities and refrigeration facilities for carrying cargo which may be changed.

The loading box of the above-mentioned refrigerated car has a box shape of a rectangular parallelepiped, and is mounted on the upper side of the chassis located on the cabin rear side of the automobile. A door for loading or unloading cargo in the cargo bay is formed on the rear or side of the cargo bay.

And the bottom plate of the loading box has a plurality of convex portions which are arranged in parallel at predetermined intervals and which are convexly bent upward so as to sufficiently support the cargoes loaded in the loading box.

However, since the loading box has various sizes depending on the size of the loading cargo, the bottom plate for the loading box can be 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 the bottom plates corresponding to the loading boxes of various sizes.

Therefore, a bottom plate corresponding to the size of the loading box is completed by manufacturing a bottom plate which is normalized to a substantially constant size and joining two or more bottom plates to each other.

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

First, the above-described conventional bottom plate welding structure is disadvantageous in that the welded portion is exposed to the outside and is not good in appearance. Since the flanges of the two bottom plates are welded together using a welding rod, the degree of bonding is weak. Therefore, there is a disadvantage in that the joint portions 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, a hole is formed at the welded portion due to thermal deformation of the flanges, which causes a risk of leakage occurring from the beginning.

In addition, the bottom surface of the loading floor of a conventional refrigerator car has a problem that the convex portion is smoothly formed, and the convex portion is put in the freezing space for the freezing facility, causing a safety accident that the operator slips and falls down during the operation.
