The present invention relates to the improvement of a pallet for a car.

[0002]

[Prior art]

 Traditionally, wooden pallets have been used for this type of cargo handling pallet in the past, but in recent years, both girders made of aluminum extruded profiles and cargo receiving plates called deck boards are welded together. There are used a structure in which the steel girder and the load receiving plate are fixed by bolts, rivets, welding, etc.

[0003] In these pallets for cargo handling, a plurality of girder materials, each of which is a side girder material or a middle girder material, which are cut into a predetermined length, are arranged in parallel with each other, and a plurality of plate-shaped girder materials are provided on the upper surface of these girder materials. The load receiving plates of the above are installed at appropriate intervals in an orthogonal manner and fixed by welding or bolts. The fork of the fork lift is inserted below the load receiving plate for loading and unloading while the load is placed on the load receiving plate.

[0004]

[Problems to be solved by the device]

 However, in the case where the girder material and the load-bearing plate are fixed by welding, if part of the girder material or the load-bearing plate is damaged by bending or cutting, it is difficult to repair the part. There was a problem that the entire pallet had to be replaced. Further, when welding a girder material made of an aluminum alloy and a load bearing plate, an oxide film cannot be formed on the surfaces of the girder material and the load bearing plate, so that there is a problem in corrosion resistance. On the other hand, in the case where the girder material and the load-receiving plate are fixed with bolts or rivets, the bolts are exposed on the surface, so not only the appearance is bad, but also the head of the bolt projects and damages the luggage. There's a problem.

The present invention has been made in view of the above circumstances, and enables repairing when a girder material or a load-receiving plate is damaged to extend the life of the pallet, and eliminates a protruding portion to the outside for loading. The purpose of the present invention is to provide a cargo handling pallet that does not cause damage to the cargo.

[0006]

[Means for Solving the Problems]

On the premise of a cargo handling pallet equipped with a cargo support plate, the above-mentioned girder material is detachably fitted to the upper girder material that is screwed or riveted to the lower surface of the above-mentioned girder plate and both sides of this upper girder material. Channel-shaped lower girder material, and both ends of the upper girder material and the lower girder material are covered with the opening girders of the lower girder material and both sides are riveted to the lower girder material. It is characterized by being fitted with a small block material.

In the present invention, the upper girder member is formed into a plate shape that is screwed or riveted to the lower surface of the load receiving plate. It is preferable to provide a standing wall.

Further, if the upper girder material and the lower girder material are detachably fitted on both sides of the upper girder material, the fitting form may be, for example, snap fitting. It is good, but one of the fitting parts of the upper girder material and the lower girder material is formed with a narrow opening-shaped concave strip, and the other is formed with a bulging convex strip that slidably fits into the above fitting concave strip. Therefore, it is preferable to slidably fit the upper girder material and the lower girder material.

[0009]
