Description

Assembly-type pallet for loading article}

The present invention relates to a prefabricated pallet for loading goods, and more particularly, to prevent easy breakage or loosening by improving the bonding strength of fastening parts, and to allow easy disassembly and assembly of fastening parts, thereby improving assembly convenience and partial It relates to a prefabricated pallet for loading goods with improved maintenance convenience.

In general, pallets are generally loaded and transported along with cargo on transportation means (aircraft, ships, vehicles, etc.) in order to stably transport various cargoes such as machined products or assembly parts. Therefore, it is most important that the pallet is lightly manufactured in consideration of the total load of the cargo while stably supporting the cargo.

These pallets are mainly composed of a plurality of pedestals in close contact with the bottom surface and a plurality of top plates arranged orthogonally to the pedestals on the top and combined to load cargo. Conventionally, pallets mainly using wood are widely used. In addition, pallets made of plastic are also proposed.

However, since the weight of the pallet made of wood or plastic is heavy above all else, it acts as a factor that increases the overall load of the cargo, resulting in a significant problem of increasing logistics costs.

In particular, in the case of wood, frequent repair or replacement is required due to various problems such as easy damage to joints fixed with nails due to its weakness in moisture, and it is also weak in strength, so it is loaded into a vehicle using a loading means such as a forklift. Due to problems such as the top plate being easily broken, its usefulness is significantly reduced, and also, due to the nature of wood, durability is weak, so it cannot be used for a long time.

In addition, the pallet made of plastic material has better durability than wood, but since the entire pallet is integrally injection-molded, partial repair is not easy, and the service life is significantly shortened.

On the other hand, recently, a pallet using a lightweight material, for example, aluminum, has been proposed in order to solve the above-described problems of the conventional pallet.

Domestic Utility Model Registration No. 336053 is one of such pallets, and its configuration is as shown in FIGS. 1 and 2. As shown in FIGS. 1 and 2, a conventional pallet has a plurality of foundations 1, a plurality of upper plates 2 coupled in a direction orthogonal to the upper surface, and a bottom surface of the foundation 1 It consists of a plurality of pedestals 3 coupled at regular intervals and a plurality of lower plates 4 coupled to the lower surface of the pedestal and parallel to the upper plate.

At this time, the pedestal 3 has a double structure having a cap 6 forming a space therein and a reinforcing member 7 inserted from the top of the space of the cap 6, but the cap 6 The lower surface and the upper surface of the lower plate 4 are configured to be mutually assembled in a concave-convex shape corresponding to each other.

The base 20, upper plate 22, pedestal 24, and lower plate 26 are mutually coupled using fastening members such as rivets or screws at each joint, but this fastening method requires only one fastening member. Since it is a method of mutually fastening by penetrating a pair of aluminum plates, there is a problem that it is easily damaged or loosened by external impact. In addition, in the case of adopting a fastening member such as a rivet, partial repair is almost impossible in case of partial damage.

Republic of Korea Utility Model Registration No. 0336053 (December 11, 2003)
