Description

LOADING PLATFORM The invention relates to a loading platform, comprising an upper cover plate, a lower cover plate and columns between the upper cover plate and the lower cover plate. These loading platforms are now used on a large scale to store and transport all kinds of products. These pallets are usually made of wood, but now for a number of uses of paper material, too, such as upper and lower cardboard cover plate and columns made of solid cardboard tubes. These cardboard loading platforms are easily recycled and are lightweight, while the wooden loading platforms are heavy, splintered and difficult to recycle. However, for certain uses the loading platform is heavily loaded as it is stacked with solid cardboard plates, for example, between which the air comes out with the help of a machine. The forces on the column of the loading platform can add up to 1500 kg since the load is not always distributed equally. A cardboard loading platform with solid cardboard columns creates spillage in the product stacked on it, as a column causes an indentation in the lower products through the upper cover plate. Consequently, wood plates are still used for this purpose up to now.

The invention is directed to eliminate the disadvantages of known loading platforms. This attempt is achieved since the upper cover plate and the lower cover plate are made of paper material and in that the columns are made of a material that can be tamped in the longitudinal direction of the columns, the ends of the columns being arranged in holes in the upper cover plate and the lower cover plate. In this way, a column, which is subject to a disproportionately high load, is tamped so that the load is distributed over all the columns. The columns made of a rolled corrugated board are very suitable since, in the direction of its face the corrugated board can be rammed into and still retains its load bearing capacity, particularly at the edge of a board, after tamp and is also stiff and strong enough in a coiled condition to take the required load. Since one or more of the columns that have been subjected to a disproportionately high load have been tamped, the load distributed over all the columns will hardly cause an indentation in the products stacked on the loading platform, so that the upper cover plates and lower can be made of paper material. In order to obtain a good fixation to the upper and lower cover plates of the columns made of rolled corrugated board, which do not have optimal fixing potential at their main end faces, the ends of the columns are arranged in holes in the plates of upper and lower cover. In this way, the loading platform is suitable for the desired purpose, and is also lighter and can be recycled more easily than a wooden loading platform. Preferably, the upper cover plate and the lower cover plate are made of honeycomb-type plates comprising a honeycomb-type core and an outer cover plate and an inner cover plate, so as to obtain a pallet of rigid load but light weight. According to an advantageous embodiment, the holes in the upper cover plate and the lower cover plate extend through the inner cover plates and the core to the outer cover plates and with their end faces the columns rest on the inner surface of the outer cover plates, so that the column can not exit outside the upper and lower cover plates and the columns can be easily and securely fixed on the upper and lower cover plates. In accordance with another advantageous modality, the holes in the upper cover plate and the lower cover plate are by passage and the end faces of the columns are at the level of the outer surface of the outer cover plates. As a result, the holes in the outer and lower cover plates are simple to make. In this embodiment, it is also advantageous that not only the edge of the hole in the inner cover plate rests against the external surface of the column, but also the edge of the hole in the outer cover plate of the type plate. honeycomb rests against the external surface of the column, so that the adoption of lateral forces on the loading platform improves and the loading platform has more resistance to shear forces. Preferably each column is provided at each end with a fixing pin having a diameter smaller than the rest of the column and having a diameter and length corresponding to the holes in the upper and lower cover plate, so that the Fixing pins are received completely in the upper and lower cover plate, and the shoulder faces that form in the transitions between the pins and the rest of the column provide additional fixing and support surfaces of the column against the plate. inner cover and upper and lower cover plate. The columns are preferably joined in the holes in the upper and lower cover plate, so that when maneuvering a loading platform does not separate. Preferably, the honeycomb-type plate top cover plate is approximately 20 mm thick, and preferably the bottom honeycomb-type plate cover plate is approximately 10 mm thick, so that the loading platform with plates of type of honeycomb is sufficiently rigid and the upper and lower cover plates of the honeycomb-type plates are sufficiently separated so that in case of shear forces through the holes the loading platform can be taken to an adequate degree. Preferably, each column of rolcorrugated board is approximately 15 mm in diameter, so that each column can take sufficient strength. Preferably, the fixing pins on the columns of the rolcorrugated board are approximately 93 mm in diameter, so that the shoulder faces at the transition between the pin and the rest of the column are sufficiently large, while the diameter of the pins it remains large enough to assume lateral forces on the loading platform. According to an advantageous embodiment, the corrugated board is selected and rolup so that a column is rammed at a load between 1000 and 1500 kg, after which other columns of the loading platform take part of the load in that column and the taming of them ceases. A disproportionately high load between 1000 and 1500 kg in a column is distributed over other columns of the loading platform by tamping on that column in some way, so that all the columns will take an approximately equal part of the load and the product in the Loading platform will not be damaged by a disproportionately high load in only one column.

Preferably, the upper and lower cover plates are approximately 1 by 1.2 meters in size. The invention will now be elucidated in more detail by a preferred embodiment based on the drawings. Figure 1 is a top view of the loading platform according to the invention; Figure 2 is a cross-section according to the line l-ll in Figure 1; Figure 3 is a cross-section in accordance with the line III-III in Figure 1; and Figure 4 is a perspective view of a column of the loading platform. According to the preferred embodiment, the loading platform according to the invention consists of an upper cover plate 1, a lower cover plate 2 and columns 3, of which, for example, they are new. The upper cover plate 1 and the lower cover plate 2 are made of honeycomb type plate, consisting of a core 4 and 5, respectively, of thin cardboard strips, formed and fixed together so that, for example , hexagonal "honeycombs" are formed, and an outer cover plate 6 and an inner cover plate 7, which are joined on both flat sides in the core 4 and 5, respectively. Preferably, the cover plates 6 and 7 consist of solid cardboard.

According to the preferred embodiment, continuous holes 8 are arranged in the upper cover plate 1 and the lower cover plate 2 for receiving the fixing pins 10 and 1 1 provided in the columns 3. The length of the fixing pins 10 and 1 1 is adapted to the length of the holes in the upper cover plate and the lower cover plate, respectively, so that they do not leave the outer cover plates. The pins 10 and 1 1 are joined in the holes 8, the shoulder faces 14 and 15 being joined on the inner surfaces of the upper cover plate 1 and the lower cover plate 2 and the edges of the holes in the plates covers 6 and 7 are joined to the external surface of the fixing pins 10 and 1 1. However, it is possible to allow the holes in the upper cover plate 1 and the lower cover plate 2 to end on the inner surfaces of the outer cover plates 6, so that the end faces 12 and 13 of the pins 10 and 1 1 are attached to these internal faces. In accordance with a preferred embodiment, the columns are made of rolled corrugated board of the one-side type, and are of a thickness so that they tamp to the required load. In the preferred embodiment, the upper and lower cover plates 1, 2 are approximately 1 by 1.2 meters in size and the upper cover plate is approximately 20 mm and the lower cover plate is approximately 10 mm thick. The columns 3 are approximately 1 15 mm in diameter, and the fixing pins 10, 1 1 in the columns approximately 93 mm in diameter. A column 3 is rammed to a load between 1000 and 1500 kg, after which other columns of the loading platform take a part of this load (disproportionately high) and the tamping of that specific column ceases. In the preferred embodiment, the corrugated board for the columns is of the E-wave type RCK 1 10/125. Finally, continuous orifices 9, approximately rectangular, are arranged in the lower cover plate 2, which serve to move the loading platform by means of a manual carriage for loading platforms on a floor, for example. It will be clear that this preferred embodiment does not limit the following rights of the claims below.
