Description

Prefabricated Pallet

The present invention relates to a pallet, and more particularly, to a prefabricated pallet that can reduce the manufacturing cost and recovery cost by simplifying the coupling structure and dismantling structure while improving the structure and weight.

In general, at the production sites of goods and storage of goods, etc., when the raw material, semi-finished product, or finished product is loaded or transported, the object to be loaded or the object to be transported is placed on a pallet as a pedestal (or loading stand). The goods are stored or loaded on pallets and are transported together with pallets by means of a forklift.

Such pallets for transporting and loading articles in general have a structure in which timbers having a constant thickness and width are intersected at right angles up and down and fastened by fastening fixtures, such as nails, at the intersection thereof. Pallets are arranged in parallel with a plurality of wood having a rectangular cross-section in parallel with each other and arranged a plurality of plate-shaped wood having a wider width than the thickness at equal intervals in an orthogonal direction at the intersection between the upper and lower members. One way is to nail them so that they are fixed to each other.

However, since the conventional pallets are first fixed at the intersection of the upper and lower members in the manufacturing step, they are fixed by nailing at the intersections thereof. When the goods are moved to the destination together with the target goods, they are usually disposed of rather than collected and used again. Therefore, the waste of resources or the difficulty of processing the wastes are a big problem.

Pallets made of conventional wood are used for storing goods in warehouses, etc., or when they are used as a place of goods stored in the open air such as bricks or stones, and when pallets are exposed to moisture or moisture, they constitute pallets. It is also pointed out that the water is soaked into the wood, which causes deformation of the wood, and the wood itself decays, resulting in unstable loading of the goods loaded thereon or a bad smell as the wood decays. .

In addition, the conventional pallet is not preferable in terms of general versatility, since a pallet having a dimension corresponding to the specific item to be transported or loaded cannot be changed since it is impossible to change its size or dimensions once it is manufactured. It has

In addition, wooden pallets have been used for a long time because they are relatively inexpensive, but they are easily damaged, so they are used less frequently and are not desirable in terms of forest protection. Therefore, wooden pallets are used to suppress or prohibit the use of wooden pallets. Industrial policies in each country are shifting.

As described above, the upper and lower integral synthetic resin pallets have been developed to compensate for the disadvantages of wood pallets, which are not only repetitive in use, but also undesirable in terms of forest protection. It is not only easy for the worker to handle, but also has a problem that the cost of recovering it is increased because the weight and volume is larger than the wooden pallet.

Therefore, in order to solve the problems of the one-piece synthetic resin pallet, a pallet that can be dismantled and assembled repeatedly has been developed. Such a prefabricated pallet can be found in Korean Registered Utility Model Publication Nos. 20-296881 and 20-314812. Started.

However, the conventional prefabricated pallets can be disassembled and assembled to form a conventional one-piece pallet, which improves efficiency in terms of recovery and transportation of the pallets. In addition to lengthening, when a member such as a metal mesh or wire forming a lattice shape is used, the appearance quality tends to be deteriorated.

On the other hand, when the goods are loaded on the pallet and exported overseas, the pallet is transported along with the goods after being unloaded from the local area to be recovered. However, when the structure of the pallet becomes complicated, there is a problem that the recovery cost incurred when the pallet is dismantled greatly increases the necessity of simplifying the structure.

The present invention has been made to solve the above problems, to provide a prefabricated pallet that can reduce the manufacturing cost and recovery cost by simplifying the coupling structure while improving the weight of the pallet structure.

5 is a cross-sectional view showing in detail the bracket of FIG.

The bracket 300 is a component for coupling the vertical member 100 and the horizontal member 200 to each other. As shown in FIG. 5, the upper fitting plate 310 and the lower fitting plate 320 are vertically spaced apart from each other. It is composed of a pillar plate 330 that is upright between the fitting plate 310 and the lower fitting plate 320. At this time, the horizontal length of the upper fitting plate 310 and the lower fitting plate 320 is the fitting space of the first coupling portion 110 and the second coupling portion 210 of the vertical member 100 and the horizontal member 200. It is formed to correspond to the width of the (115, 215).

And the horizontal length of the column plate 330 is the locking space 116 between the side engaging plates 111 and 211 and the center engaging plates 112 and 212 of the first coupling portion 110 and the second coupling portion 210. , 216 is formed. That is, the upper fitting plate 310 and the lower fitting plate 320 of the bracket 300 are formed in a square equal to the distance between the fitting spaces 115 and 215, and the pillar plate 330 is the locking space 116, 216. It is formed in a square equal to the distance between the two. The thickness of the upper fitting plate 310 and the lower fitting plate 320 is smaller than or equal to the height of the fitting spaces 115 and 215. And the height of the column plate 330 is formed to be greater than or equal to twice the thickness of the side engaging plates (111, 211) or the center engaging plates (112, 212).

In this case, a plurality of protrusions 340 are formed on the inner surface of the bracket 300 like the first coupling part 110 and the second coupling part 210.

As such, the reason why the protrusions 118, 218, and 340 are formed on the inner surfaces of the first coupling part 110, the second coupling part 210, and the bracket 300 is that the first coupling part 110 and the second coupling part are formed. When the bracket 300 is inserted between the parts 210, the bracket 300 is provided to eliminate the play between the bracket 300 and the coupling parts 11 and 210.

The following briefly describes the coupling method of the vertical member 100 and the horizontal member 200 formed as described above.

In order to combine the vertical member 100 and the horizontal member 200, first, the plurality of vertical members 100 are arranged in parallel with each other at desired intervals. The length of the vertical member 100 and the distance between the vertical members 100 are set to fit the horizontal length of the pallet to be manufactured.

The horizontal member 200 is orthogonally coupled to the vertical members 100 arranged as described above, before the horizontal member 200 is coupled, first, the bracket 300 is installed.

Since the fitting space 115 of the first coupling part 110 is two or three, two or three brackets 300 are positioned on the same line.

When the bracket 300 is installed, the horizontal member 200 is coupled to the brackets 300 to be perpendicular to the vertical member 100. At this time, the horizontal member 200 will be preferable to arrange as closely as possible so that the seat is seated. Alternatively, after the horizontal member 200 is cut at a predetermined interval, the horizontal member 200 may be installed between neighboring horizontal members 200 to be used as a gap adjusting means of the horizontal members 200.

Since the projections 118, 218, and 340 are formed in the vertical member 100, the horizontal member 200, and the bracket 300, which are coupled as described above, even if there is a certain degree of fitting tolerance, the play does not occur due to the projection. After coupling, the bracket 300 may fall out or the horizontal member 200 may be prevented from being separated from the vertical member 100.

If it is necessary in this manner, the horizontal member 200 may be further coupled to the lower surface of the vertical member 100.

On the other hand, it is also possible to bolt the vertical member 100 and the horizontal member 200 in order to more firmly coupled to the assembled prefabricated pallet as described above.

Then, the nut is fastened to the screw portion of the ring bolt 400 inserted into the mounting groove 230 and fixed at the top.

By the bolt coupling, the two-dimensional coupling force of the vertical member 100 and the horizontal member 200 was increased.

On the other hand, when the horizontal member 200 is mounted on the vertical member 100 may be used as a spacer 200 'by cutting the horizontal member 200 to an appropriate size in order to fit the gap between the horizontal members 200. That is, the spacer 200 ′ is coupled to the vertical member 100 in a direction perpendicular to the arrangement direction of the horizontal member 200. In addition, grooves are formed on the upper surfaces of the horizontal members 200 in the longitudinal direction thereof, and a right angle groove extending from the spacer 200 'may be further formed to intersect the grooves.
