The present invention relates to a steel pallet, and more particularly, to form upper and lower plates and legs and support members in a state in which wrinkles are formed on a relatively thin steel plate to increase its strength, as well as openings at both ends of the legs and support members; The inner part is provided with a cap and a reinforcing member, and if necessary, the safety member is coated on the upper and lower end portions, or the safety member is integrally bent on the outer upper surface of the leg and support member. Press-fitting through press enables mutual coupling (ie, cocking assembly), greatly reducing assembly time and cost, and automating the production of steel pallets, and increasing the weight of the steel pallet itself. It can be greatly reduced and lightened, and the strength of each member can be greatly increased by corrugated force ribs and reinforcing members, and the amount of upper and lower plates It is protected by a safety member provided on the safety member or the foot supporting member cum coating to add itself to the invention to secure the safety.

In general, pallets are indispensably used to easily or quickly and accurately handle transportation and storage by producing various goods or products in an industrial site or a distribution business.

By the way, the pallets used for transporting and storing the goods are mostly composed of the form of squeezing wood having a certain thickness or width into a lattice form and fastening fixtures such as nails at the intersection thereof. There was a problem that the service life is short.

In particular, when the wooden pallet is used as an appropriate place for items stored in the open air such as brick or stone, the pallet is exposed to moisture or moisture, causing the wood to be dehydrated, resulting in the deformation of the wood, while the wood is rotten and moldy. Will cause bad smell and damage to the load stored in the upper part of the pallet.In addition, raw materials are mostly dependent on imports, causing foreign currency waste, resource waste and environmental pollution. It was.

Therefore, in recent years, a pallet made of a synthetic resin (plastic) has been utilized to reinforce the corrosion and strength which is a disadvantage of the wood.

By the way, the pallets made of synthetic resins are mass-produced and reinforced in strength, which extends their service life compared to conventional wooden pallets. It causes dropping, which greatly increases the logistics cost, and also causes the environmental problems due to the inability to recycle materials at the time of disposal.

On the other hand, in recent years, in order to supplement the above problems, a pallet using steel sheet has been produced, but most of the number of parts, such as the rise of manufacturing costs and difficult automation of mass production has emerged, and each component is welded or In the case of welding, the production cost is high, and in the case of welding, the bolt is easily released due to vibration and load when used for a long time.

In addition, in some cases, the entire steel pallet is manufactured integrally up to the legs. In this case, there are problems such as excessive input of equipment costs, and the overall weight of the steel pallet is excessively increased and the production cost is greatly increased. Of course, there are many problems in use.

Therefore, the present applicant has proposed a number of domestic patent applications 2004-108331, 2005-51713, 51714, 51715, 51716 and 64652 as a way to improve the problems with such a conventional steel pallet have.

At this time, among the patent applications No. 2004-108331 proposes a surface treatment method for enhancing the anti-slip and corrosion resistance and wear resistance of the steel pallet, 2005-51713 is the strength of the intermediate support of the steel pallet In the case of 2005-51714, the surface of the steel pallet is coated to provide anion and far infrared rays. In 2005-51715, the upper and lower plates of the steel pallet are specially fastened. A side safety pallet is proposed to enable mutual fastening without a device, and 2005-51716 proposes a structure that can be joined without external media by forming a recess and a coupling protrusion in an intermediate member of a steel pallet. 64652 proposes a structure in which each component of a steel pallet can be mutually bonded through compression bonding.

However, the steel pallet of the above-described application has the shape of the bridge to serve as an intermediate member that connects the upper and lower plates, so that the upper and lower plates can not only exist at the same time, these upper and lower plates, By connecting the bridge through several legs, the number of parts constituting the pallet and the number of parts to be joined are increased, which increases the production cost of the product due to the increase in the number of production processes.

In addition, in the coupling of the upper plate, the lower plate and the middle plate, technical methods such as fastening, welding, and rivet joints are used, but all of them consume excessive labor costs and technical difficulties, as well as use in the field after production. There were a lot of cases.

In other words, the fastening of the piece is solid, but it is weak in vibration, labor costs in the process are high, and automation is difficult, and the welding method is difficult according to the working conditions. The cost was not adequate in terms of cost and quality.

In addition, since the legs do not support the entire upper and lower plates, the lower and lower plates have only a part of the supporting plate fixed to each other, so that the bending strength of the upper and lower plates is weak and of course requires a separate supporting plate. As described above, the number of parts and the number of assembly processes are high, resulting in a large production cost of the product.

In addition, the free end portions of the upper and lower plates that are bent in a zigzag form are exposed from both sides of the pallet at the upper and lower sides thereof, so that the operator may be injured by the sharp free ends of the upper and lower plates while handling the pallet. .

In addition, the fork-shaped legs of the forklift truck have a form in direct contact with the bottom of the steel pallet or the bottom of the support plate which fixes the top plate when carrying various items through the pallet using the forklift. Including a lot of load is applied to the coupling portion of these and the legs, there is a disadvantage that the top plate and the support plate is bent or the coupling portion is damaged and shorten the life and inconvenience of use.

The present invention has been made in order to solve such a conventional problem, the first is to automate the production of steel pallets and at the same time can reduce the number of components and significantly reduce the assembly time and production costs, the second steel pallet itself The weight can be greatly reduced, and the weight can be reduced. Third, the strength of each member can be greatly increased through the corrugated force part and reinforcement member. Fourth, the upper plate and the lower plate are made of the safety member coated on its own or formed on the leg and support member. It is possible to secure the safety of the operator by protecting the sharp both ends of the upper part, and to prevent the deformation of the upper and lower plates by supporting the upper plate or the upper and lower plate through the whole leg and supporting member equipped with the fifth cap and the reinforcing member. On the sixth leg and the supporting member to form an insertion hole into which the fork-shaped legs of the forklift can be fitted, The steel pallet is capable of preventing the bending of the upper and lower plates or the leg and support members or the damage of the coupling part when transporting various items through the pallet by bending the reinforcing pieces. The purpose is to provide.
