A pallet is a pedestal for loading various loads used when carrying loads by a forklift, etc., and is generally formed in a rectangular plate shape and manufactured using metal materials such as wood, synthetic resin, and aluminum.

Wood pallets have the advantages of low material cost, but they are not only susceptible to impact but also can easily propagate various pests and bacteria, which can introduce foreign pests during the import and export process. In particular, there is a disadvantage that increases the cost during air transportation.

Synthetic resin pallet has a high price of synthetic resin as a raw material, and has to produce injection molds according to specifications, so that the economic burden to cope with specification changes is high, and it is not easy to recycle, contaminating the environment.

As an alternative to this problem, a metal pallet using aluminum or the like is used.

Aluminum pallets are lightweight, so they can reduce costs, especially during air transportation, and there is no fear of damage or propagation of bacteria, and they can be recycled to minimize environmental pollution.

Hereinafter, an embodiment of an improved metal pallet according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the metal pallet 1 having improved economical efficiency according to the present invention includes a plurality of spacers for supporting the upper plate member 20 while providing a transport fork insertion space S. spacer) 10 and a plurality of top plate members 20 positioned on an upper surface of the spacer 10 and made of a metal material including aluminum, wherein the spacer 10 is formed on one or more horizontal partition walls 113 or ribs. It includes at least one vertical member 11, the inner space penetrating in the transverse direction divided into two or more layers and at least one horizontal member 15 penetrating the vertical member space and coupled with the vertical member 11 The vertical member 11 is made of metal, including aluminum, and the horizontal member 15 is made of any one or more of metal, including bamboo, wood, mixed wood, and synthetic resin.

Here, the spacer 10 is a plurality of vertical members 11 are arranged in a chopped form, the horizontal member 15 is made through the top layer space of the plurality of vertical members 11 or the top and bottom layer space is coupled through, the vertical The member 11 and the horizontal member 15 may be in the form of an extruded tube made of a metal material including aluminum and the whole or part of the inner space is closed.

The vertical member 11 is a tubular body in which an inner space is partitioned into two or more layers by at least one horizontal partition wall 113, that is, a closed cross-sectional shape in which the inside is partitioned into a multilayer space, and the horizontal member 15 is formed. May be coupled to the uppermost layer or the uppermost layer and the lowermost layer of the inner space of the vertical member 11 (see FIGS. 1 to 4).

The vertical member 11 has a high mechanical strength since the inner space is closed, and the one or more horizontal bulkheads 113 that partition the inner space provide a strength against impact and pressure in the vertical and horizontal directions. Reinforce.

The characteristics of the present invention is such that the upper portion of the vertical member 11 is stacked on the horizontal member 15 by the horizontal member 15 penetrates into the vertical member 11 so that the upper plate member ( 20, the thickness of the fastening portion is doubled, thereby reducing the thickness of the two components of the horizontal member and the vertical member in half and having sufficient strength necessary for the spacer without additional reinforcing material (FIGS. 3 and 4). Reference).

The cross-section of the corresponding space and the horizontal member is formed to correspond to each other through the horizontal member 15 to be coupled to the vertical member 11, the chamfer so that the coupling space 16 for the spacer closing cap 17 is formed Base 156 may be formed (see FIG. 3).

The closing cap is preferably provided at both ends of the upper plate member 20 or the lower plate member 30 as well as the spacer 10 (not shown).

In the above configuration, when the thickness of the vertical member 11 and the horizontal member 15 forming the spacer 10 is reduced, the rivet 51 is preferable as the fastening means 50. However, the rivet fastening is difficult to disassemble and repair after assembly. have.

As shown in FIG. 5 as a spacer of an embodiment according to the present invention, the horizontal member 15 is a core insertion horizontal member 15C into which the core C is inserted and coupled to an inner space, and the core C Is made of any one or more of wood, synthetic resin and mixed wood, including bamboo materials to facilitate the use of screws in the assembly of spacers and top plate members.

In addition, the core C may be inserted over the entire length of the horizontal member 15 or in the form of a piece corresponding to the position where the fastening means 50 enters.

The core (C) is made of a bamboo strip or bamboo aggregate, the bamboo aggregate may be a plurality of bamboo strips are joined in a single body or by crushing and then crushed bamboo finely crushed.

Bamboo is an excellent structure with tensile strength 6 times that of steel. It has good mechanical strength, low material cost, and significantly lower carbon gas emissions than metal materials in production and processing.

The bamboo strip is processed in the form of a square bar having an arbitrary cross-sectional shape by splitting the bamboo, and the fiber density gradually decreases from the surface layer of the dense tissue to the inner layer of the relatively soft tissue. The layer is removed and the portion from the surface layer to the middle layer is used.

In addition, the bamboo aggregate may be subjected to a carbonization process.

The core C, which is made of the bamboo aggregate material, increases the fastening force of the screw 53 of the upper plate member 20 to the spacer 10 and increases the strength of the spacer 10.

Here, as shown in FIG. 6, the core insertion horizontal member 15C is formed by dividing the inner space into two or more zones by one or more vertical walls 25 or horizontal partition walls. It can be inserted into one of the two or more zones into which the screw 53 enters the fastening means 50.

Such a configuration increases the fastening force at the time of assembling the upper plate member 20 using the core C and reduces the cross-sectional area of the core C to reduce the weight of the pallet.

On the other hand, when the pallet includes the core (C) made of bamboo aggregate, etc., there is a fear of pests or bacteria growth, and damage by rainwater may occur during the yard.

In order to prevent this, in the case of the bamboo aggregate material forming the core (C), the first self-protection is made by first sterilizing the bamboo strip with high-temperature, high-pressure fumigation and then collecting.

In addition, the core insertion horizontal member 15C may be secondly waterproofed and insectproofed by impregnating and coating paraffin at both ends in a state in which the core C is inserted into the horizontal member 15.

The paraffin-impregnated coating of the core insertion horizontal member 15C is a structure in which the core C is exposed to the paraffin melt, that is, the ends of the core insertion horizontal member 15C are immersed in the structure of the core C, the horizontal member 15. The paraffin is impregnated in the gap between and the core (C).

Then, the core insertion horizontal member 15C is taken out of the paraffin melt and then quenched and hardened so that the paraffin is filled with paraffin between the structure of the core insertion horizontal member 15C and the gap between the horizontal member 15 and the core C with paraffin. This is done.

Thus, the core (C) made of the bamboo aggregate material is combined with the horizontal member 15 after the first self-prevention treatment is made and the secondary paraffin impregnation coating is made to prevent biological contamination or moisture penetration after the product.

In addition, the core (C) may be made of a flame retardant coating to have a flame retardancy.

Any one or more of the vertical member 11 or the horizontal member 15 may be continuously formed with one or more of one or more protrusions 115, 155 or ribs to facilitate insertion and gripping of the horizontal member or core ( 3, 5)

The protrusions 115 and 155 facilitate the insertion of the horizontal member or the core, and the receiving space of the bur b which may be generated by the entry of the screw 53 when assembling the upper plate member to the spacer. To make the assembly stable (see FIG. 5).

The spacer 10 and the upper plate member 20 are coupled using the rivet 51 or the screw 53 as the fastening means 50, and the upper plate member 20 is shown in Figs. One or more fastening slots 21 for preventing protrusion of the fastening means 50 and one or more unevennesses 23 and two or more vertical walls 25 for preventing slips of the load may be extruded continuously. Can be.

In addition, a V-groove 211 for guiding the inlet of the fastening means may be formed in the center of the fastening slot 21 (see FIG. 7).

The upper plate member 20 may be in the form of a tube (see FIG. 7) in which the inner space is closed or in a variety of forms in which a part of the lower part is opened, and in the form of an open part of the lower part, the part is opened in the form of a tube ( 8 may be in any of various forms, such as a and b of FIG.

In addition, a plurality of lower plate members 30 may be arranged and fixed below the plurality of spacers 10.

The lower plate member 30 may be installed symmetrically with the upper plate member 20 below the vertical member 11.

In the drawings, reference numerals 27, 117, and 157 denote fastening holes formed in the upper plate member, the vertical member, and the horizontal member, respectively.

It looks at the assembly and operation state of the metal pallet (1) with improved economics according to the present invention having such a configuration.

According to the present invention, the horizontal member 15 penetrates into the vertical member 11 so that a part of the horizontal member 15 functions as a reinforcing member, thereby providing the necessary strength for the vertical member without a separate reinforcing member and the vertical member 11. The upper surface and the horizontal member 15 of the form is stacked is doubled in thickness.

Accordingly, even if the thickness of the vertical member 11 and the horizontal member 15 is half, the spacer 10 has a thickness sufficient to assemble and fasten the upper plate member 20 to reduce materials and manufacturing costs (FIGS. 3 and FIG. 4).

In addition, as described above, the reinforcing material is unnecessary and the horizontal member 15 is laminated to the vertical member 11 through a stack, that is, the circumference of the vertical member 11 in the form of a closed extruded tube fragment Since the horizontal member 15 in the form of a closed extruded tube is sewn, the vertical member 11 and the horizontal member 15 are assembled and assembled as they are without post-processing after cutting to a predetermined length, respectively, in the prior art It is very easy to manufacture and simple assembly flow because it does not require post-processing such as the formation of grooves, which greatly improves productivity.

In addition, when the spacer 10C becomes the core insertion horizontal member 15C, the fastening force of the screw 53 is remarkably increased when the upper plate member is assembled.

When fixing the top member 20 by using the screw 53 to the spacer (10) (10C), first to form a fastening hole (27) through which the screw can easily penetrate in the corresponding position of the top member (20) The vertical member 11 is formed with a tapping hole 117 of a smaller size than the fastening hole 27 so that the screw thread is formed by the entry of the screw is made.

FIG. 11 is a view for explaining an operation state when assembling the core insertion spacer 10C and the upper plate member 20, and shows the screw 53 when the core C is not present.

As shown in FIG. 11, when the screw 53 is fastened for assembling the upper plate member in a state in which the horizontal member 15 does not have the core C, the screw 53 is the vertical member 11 and the horizontal member 15. In the process of entering the thread while forming a thread), the stress for the entry of the screw 53 is concentrated in the place where the screw is drilled, in particular, the lower surface of the horizontal member 15 and the horizontal partition wall 113 of the vertical member 112 Deformation in which protrusions P are generated on the upper surfaces of the horizontal member and the vertical member 11 inversely occurs due to the concentrated stress generated when drilling, and the spacer 10 and the upper plate member 20 are caused by the protrusions P. A gap (s1) is generated between the () becomes unstable assembly.

In addition, when the protrusion 115 is not present in the vertical member 11, a deformation is generated between the horizontal member 15 and the vertical member 11 due to the burr b generated by the fastening of the screw 53. The state becomes bad (see Fig. 11).

In contrast, as shown in FIG. 5C, in the case of the core insertion horizontal member 15C into which the core C made of bamboo material or the like is inserted into the horizontal member 15, the screw 53 is a vertical member 11. ), Since the fastening force is increased at the same time as the horizontal member 15 and the core C are simultaneously tightened, the stress generated in the vertical member 11 and the horizontal member 15 due to the entry of the screw 53 has a large cross-sectional area (C). Diffused to the entire area of the) to prevent the protrusion deformation of the upper surface of the vertical member (11) and the top plate member 20 and the spacer (10C) is closely assembled.

In addition, even when burrs b are generated on the vertical member 11 and the horizontal member 15 when the screw 53 is fastened, the protrusions 115 formed on the vertical member 11 provide burrs b containing space so that assembly is easy. It becomes stable (see c of FIG. 5).

In summary, the spacer 10C including the core includes a vertical insertion member 11 and a horizontal member having a core insertion horizontal member 15C formed by coupling a core C made of bamboo aggregate or the like into the horizontal member 15. In the state in which the female thread is not formed in the member 15, the screw 53 is threaded directly through the core insertion horizontal member 15C from the upper surface of the vertical member 11 to the horizontal partition wall 113 and is directly fastened to the spacer. At the same time to significantly increase the fastening force for fixing the upper plate member 20 to 10C to simplify the assembly operation simple.

In addition, since the spacer 10C including the core is inserted into the horizontal member 15, the core C made of a bamboo material and the like is inserted into the reinforcing material, thereby minimizing the cross-sectional area of the metal material such as aluminum, and the whole is made of metal. Compared with aluminum pallets, the mechanical strength is good, and at the same time, expensive metal materials such as aluminum can be saved to significantly reduce manufacturing costs.

In other words, when assembling using a screw in an existing aluminum pallet, a female thread should be formed in the spacer, and for this purpose, the spacer should be of a considerable thickness. However, when the core insertion horizontal member 15C is provided, the vertical member 11 The screw is entered in the state in which only the tapping hole is formed without forming the female screw, so that the screw thread is directly formed on the vertical member 11 and the core insertion horizontal member 15C. And it is possible to reduce the thickness of the horizontal member 15 to 1mm or less can significantly reduce the manufacturing cost.

In addition, the core insert spacer (10C) is the core (C) made of a bamboo material stronger than steel is inserted into the load capacity is increased to significantly improve the quality characteristics of the pallet.

In addition, the core (C), which is made of bamboo aggregate, etc., is self-protected by the first fumigation treatment, and is inserted into the horizontal member (C), and the paraffin coating is then made waterproof and insect repellent, thereby causing secondary biological contamination. Because it is prevented, including wood cores such as bamboo material does not impair the advantages of waterproof, insect-proof aluminum pallets.

In addition, since the bamboo material having excellent profitability as a natural material is used as a pallet material, there is an advantage of contributing to the protection of the global environment by controlling metal resources with high carbon gas emissions in production and processing.

In addition, it is prefabricated using screws to enable direct repair and repair of the consumer.

As described above, the metal pallet with improved economical efficiency according to the present invention has a sufficient strength required by a relatively small cross-sectional area without a separate reinforcement because the spacer is coupled horizontally through the vertical member horizontal member

Firstly, it significantly reduces the required weight of raw materials,

Secondly, since the cumbersome post-processing using a milling or press machine is unnecessary after cutting the material, processing cost is minimized.

Third, the assembly labor and cost are reduced by the simple assembly using a screw, etc., excluding welding.

fourth. It is a prefabricated type using screw, which enables direct repair and repair by the consumer.

Although it has many advantages such as light weight, waterproof, insect repellent, pollution prevention, flame retardancy, resource recycling, etc., the aluminum pallet, which was difficult to use due to a large economic burden, can be widely used with a light burden, and thus the industrial applicability is very good.

The metal pallet 1A of which the economical efficiency of the present invention is improved is composed of a single body 11 in which the spacer 10A extends the vertical member 11 described above over the entire length of the spacer, and the core C is inserted. As such, the body 11 integrally performs the functions of the vertical member 11 and the horizontal member 15 as a single body.

The spacer 10A having such a configuration has the same effect as the metal pallet 1 of the embodiment having the spacer 10C having the core insertion horizontal member 15C in terms of increasing screw fastening force, and the number of parts. There is an advantage that the production is significantly easier by reducing the.

In addition, as shown in Figure 9c, by forming one or more vertical walls 114 in the interior space of the body (11A) to divide the interior space into two or more zones of the core insertion space and the core (C) The cross-sectional area can be reduced.
