Description

Bottom plate for van loading box {FLOOR BOARD FOR FREIGHT VEHICLE CARGO BOX}

The present invention relates to a bottom plate for a freighter loading box, and in detail, to form a horizontal plane, by forming a rail for inserting skates on both sides with respect to the center portion to the loading of cargo vans to facilitate loading and unloading It is related to the bottom plate.

In the case of logistics movement using vans, many parts are involved in the transportation of logistics, and most of the vans are equipped with an open type loading box. In recent years, there has been a problem in that the merchandise of the product may be deteriorated due to the impact of the product from the outside during the transportation of the cargo, A lid device of various configurations capable of keeping the loading box in a hermetically closed state is proposed.

The wing body is provided as a representative example, and the wing body (wing body) is a device that loads and unloads a side door like a big bird's wing, and has excellent work efficiency, easy operation, and excellent load capacity.

That is, the wing body will be described in more detail. The wing body can be freely transported regardless of the weather conditions, thereby improving the transportation efficiency. Further, the rope and lid work are unnecessary, thereby enhancing the safety of the loading and unloading operation. The wing body to which the electric hydraulic power pack with the hydraulic pump is integrated can be easily opened and closed with one button, and it is possible to open and close the side gate wing easily by installing the check valve alone.

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 at a strength capable of sufficiently supporting the cargoes loaded on the loading boxes of the wing bodies.

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 order to solve such a problem, Korean Patent Registration No. 10-0797097 filed by the present applicant and registered (the bottom plate structure of a loading car of a specially equipped vehicle) is published.
