KR20000059074A - Lightweight Prefabricated Steel Pallets - Google Patents

Abstract

PURPOSE: A lightweight steel pallet is provided to assemble simply and conveniently by using members at a minimum, to provide a steel pallet which is solid in construction and lightweight by assembling with bolts without welding or using additional means, to prevent the corrosion and vary the color by performing the zinc galvanizing or the ceramic treatment on the steel surface and to provide environmentally friendly products to have a high competition in transportation. CONSTITUTION: A lightweight steel pallet includes an upper board having roll-formed members (1,2), legs (3,4), which are formed by a press molding, assembled to the upper board and bolts connecting the upper board and the legs. The members are in a surface-contact with each other by the bolts without interval, and are treated with embossment.

Description

Lightweight prefabricated steel pallets {.}

The present invention relates to a lightweight assembled steel pallet, and more particularly, the horizontal member, the vertical member, and the leg member constituting the pallet are tightly assembled to each other without being spaced apart from each other, while the assembled pallet is easily disassembled when disassembled. It relates to a lightweight assembled steel pallet configured to be.

Until now, the technology has been used to stably stack various cargoes or use pallets to quickly load and unload cargoes to and from trucks. It is an iron pallet that can be easily exchanged to prevent waste of resources and environmental pollution, while minimizing the weight of the pallet, maximizing its own strength, increasing the loading efficiency of cargo and reducing logistics costs.

In general, a conventional pallet for transporting and loading goods is composed of a frame having a certain thickness or width in the form of a lattice, and fastening fixtures such as nails at the intersection thereof. This is a short problem. Especially, when the pallets are used for storage of open goods such as bricks or stones, when the pallet is exposed to moisture or moisture, the wood will get wet and cause the wood to deform and deteriorate. In some cases, the loading state of the goods loaded thereon may be unstable or the wood may be corroded, resulting in a bad smell. And after the end of life, it cannot be recycled and must be completely discarded, and there are many problems such as waste of foreign currency, waste of resources, and environmental pollution caused by the total dependence on imports from foreign countries.

In addition, pallets made of synthetic resin (plastic) are being used to reinforce corrosion and weak strength, which are disadvantages of wood.

However, pallets made of synthetic resins have a heavy weight because they are mass-produced and strengthened in strength, which extends their service life compared to conventional wooden pallets. Therefore, there is a disadvantage in that the loading efficiency is lowered, causing a large increase in logistics costs and recycling is impossible.

Recently, pallets made of steel have emerged to compensate for this problem. However, the number of parts and especially the combined parts of welding have caused problems of scraping the entire welded part and the number of parts even if some parts are damaged. have.

Therefore, the present invention is very simply assembled for the purpose of solving the above problems, and is easy to assemble using a minimum number of members, the structure is robust and lightweight at the same time, and the steel surface is galvanized or ceramic treatment to prevent corrosion and It is beautiful in appearance and can be diversified in color, making it easy to identify pallets and providing environmentally friendly products to contribute to transportation competitiveness.

The following description will be made based on the SJP A-type, which is an exemplary drawing, and other types are replaced by the drawings.

1 is an external view of a lightweight assembled steel pallet SJP A-type according to the present invention.

As shown in the drawing, in the SJP A-type, the constituent members are composed of roll formed (1) and (2) members to form a top plate, and the legs (3) and (4) formed by press molding are fitted to the top plate. After that, connect the body connecting bolt (4) and the bridge connecting bolt to form a lightweight assembled steel pallet. The main point here is that the members 1, 2, 3 are brought into contact with each other by the bolts without gaps.

Therefore, the pallets are firmly coupled to each other, so that the pallets are formed of excellent binders to support the load.

The above-mentioned wood, plastic, welded steel, and the parts of the assembled pallet, which has many kinds of parts, are supplemented and the main members are produced by continuous roll forming, which enables the mass production and automation, thereby reducing the production cost. will be.
