Description

Process for ready-to-transport stacking of percolating block elements on a sea container-suitable pallet

The invention relates to a method for ready-to-transport stacking of percolating block elements on a sea container-suitable pallet according to claim 1.

State of the art

It is known, for a transport in a high-cube sea container, to arrange seepage block elements with a base area of 80 cm × 80 cm for utilizing the inner width of the sea container on three adjacent pallets, so that an upright one on each of the two outer pallets Stack of 34 percolating block elements is arranged and arranged on the middle pallet three stack with six per block elements on top of each other. That is, you need two pallets of about 80 cm x 80 cm and a range of about 80 cm x 73 cm. The loading and unloading of the prepared for transport pallets is complicated, since three pallets must be moved. The packing and unpacking of stacks of the middle pallet is more complex than that of the side pallets.

EP 2 980 328 A1 discloses seepage block elements having a base wall which has a square base surface, wherein hollow columns are connected to the base wall. The columns are designed and arranged such that, in the case of two identical and identically aligned percolating block elements, the columns of the upper percolating block element can be introduced into the columns of the lower percolating block element, and a stack of percolating block elements can be formed. In addition, block filter elements are disclosed having a base wall with a rectangular base, wherein such a block filter element of two identical Sickerblo- ckelementen each having a base wall with a square base, which are arranged side by side in the same orientation corresponds.

Sea containers, also called ISO containers, can be defined by the ISO 668 standard.

task

It is an object of the present invention to enable an efficient transportable stacking of percolation block elements for a transport with a shipping container.

solution

This object is achieved by the method according to claim 1. Preferred embodiments are disclosed in the dependent claims.

The method according to the invention for ready-to-transport stacking of percolating block elements on a sea container-suitable pallet comprises the steps:

- providing a sea container-suitable pallet, - Providing a stack or more stacks, each with a plurality of nested block block elements and a final percolating block element, wherein the percolating block elements each have a base wall with a square base or a rectangular base surface, wherein per block the percolation block elements are of identical design and

- Laying one or more stacks horizontally on the sea container-suitable pallet.

A square base area as a special case of the rectangular base area is explicitly mentioned in order to be able to explain a difference to the rectangular, non-square base area. In the following, when the term "rectangular" is used, it is to be understood that it is somewhat rectangular, but not square. If rectangular also includes square, this is explicitly mentioned.

It may be provided that a single sea container-suitable pallet is provided for arranging the one or more stacks. This totality of pallet and stack / stacks can be called a transport unit. Such a transport unit may also comprise securing means for securing the stack or stacks on the pallet and / or a transport or bottom plate respectively arranged on the final percolating block element. A sea container can be equipped with one or several transport units.

Due to the horizontal arrangement on a single pallet, a simple packing and unpacking is possible because only one orientation of the stack is given. In the shipping container, the available floor space can be optimally utilized (> 90%). The loading and unloading of such a packed pallet is economical.

As the final blocker block element, that block of percolating block is referred to, in which another percolating block element is stacked, but the final percolating block element is stacked in no further percolating block element.

A percolating block element may have a base wall with a square base area of 80 cm x 80 cm, with a base connected to a plurality of hollow pillars. Alternatively, a percolating block element may have a base wall having a rectangular footprint of 100 cm x 50 cm, 120 cm x 60 cm, or 160 cm x 80 cm, with a base connected to a plurality of hollow pillars. For the embodiments with a square base area or rectangular base area, the columns can have a length of 37.1 cm, starting from the top side of the base wall. A stepped tip at the end of the column may have a length of 1.7 cm. The thickness of the base wall can be 4 cm. Through the hollow columns, the Sickerblockelement are intertwined stackable, with an operating distance of 2 cm between an underside of a first base wall and an upper side of a second base wall can be formed.

As a sea container suitable pallet can be considered a pallet having a rectangular or square transport surface, in which two opposite sides have a length which is 2% to 3% shorter than the inner width of the sea container. With an inside width of 233 cm, the length of the two opposite sides could each be between 226.01 cm and 228.34 cm. The height of the pallet can be between 13 cm and 15 cm.

Thus, with a width of the 80 cm pallet, it would be possible to arrange a stack of 32 seepage blocks with a square base on the pallet. With a width of the 160 cm pallet, it would be possible to arrange a stack of 32 bead block elements with a rectangular base area on the pallet. In both cases, the stack could also have a transport plate or bottom plate with a thickness of 4 cm to protect the pillars during transport. Such a stack would have a length or height of 225.4 cm. Preferably, the transport plate or the bottom plate is constructed similar or equal to a base wall of the percolating block element.

Sea containers can be standard 2071 CC (inner width 2.33 m, door height 2.28, inner length 5.89 m), standard 40V1AA (inner width 2.33 m, door height 2.28 m, inner length 12.01 m) or high-cube 4071AAA (internal width 2.33 m, door height 2.56 m, internal length 12.01 m). In a 4071 AAA High Cube, three stacks of percolating block elements with a square footprint can be stacked on a pallet and 15 such loaded pallets can be placed in the sea container, for a total of 1440 percolator elements.

In the arrangement known from the prior art, only 1290 seepage block elements with a square base area with 15 pallets can be accommodated in the sea container. The arrangement according to the invention makes it possible to arrange 1 1% more bead block elements in a sea container.

A first layer of the one or more stacks can be arranged on the pallet in such a way that one of the four outer sides of the perimeter block elements can come to rest on the transport surface of the pallet.

Due to the flying up of the outer sides on the transport surface, a tilt-safe storage of the stack can be achieved due to the support surface and because the greater weight proportion of the stack is given by the base surfaces, while the non-supporting columns make up the smaller weight fraction of the stack. A second layer of the plurality of stacks can be arranged on the first layer such that one of the four outer sides of the perimeter block elements of the second layer can each come to lie on a respective second one of the four outer sides of the perimeter block elements of the first layer.

With multiple stacks, a first stack can be placed in a first position directly on the pallet, i. on its transport surface, and a second stack can then be arranged lying on the first stack, wherein both stacks can have the same orientation. In case of intended transport in a high-cube sea container, a third layer may be provided due to the door height of the sea container.

In the case of square base blocks, with a pallet width of 80 cm, it is possible to place three stacks one above the other in three layers on the pallet for transport in a high cube sea container.

The provision of a stack or a plurality of stacks may include that a respective transport plate or a bottom plate is arranged on the final percolating block element. The transport plate or the bottom plate can protect the column tips during transport. Also, by the transport plate or the bottom plate, the stability of the stack can be increased.

The method may further comprise securing the one or more stacks on the pallet by securing means. The securing means may comprise pallet straps or PP strapping bands.

The attached figures represent by way of example for better understanding and illustration aspects of the invention. It shows:

Figure 7 schematically, twelve transport units. 1 shows an arrangement of stacks 6, 7, 8, 9, 10 of blocker block elements 1 with a base wall with a square base on three pallets 3, 4, 5 according to the prior art. For transport in a high-cube sea container, the bead block elements 1 with a base area of 80 cm × 80 cm are arranged on the three pallets in such a way that the two outer pallets 3, 5 each are used to utilize the inner width of the sea container An upright stack 6, 7 of 34 percolating block elements 1 is arranged and on the middle pallet 4 three lying stacks 8, 9, 10 each with 6 percolating block elements 1 are arranged one above the other. The stacks 6, 7, 8, 9, 10 of blocker block elements 1 each comprise a transport plate 2 or bottom plate 2. That is, there are two pallets 3, 5 of about 80 cm x 80 cm and a pallet 4 of about 80 cm x 73 cm needed. The loading and unloading of the prepared for transport pallets 3, 4, 5 (ie with the stacks 6, 7, 8, 9, 10 equipped pallets 3, 4, 5) is complicated, since three pallets 3, 4, 5 are moved have to. The packing and unpacking of stacks 8, 9, 10 of the middle pallet 4 is more complicated than that of the side pallets 3, 5.

FIG. 2 shows the arrangement according to the invention of the filter block elements 1 stackable on a sea container-suitable pallet 14 with a base wall with a square base surface, wherein the filter block elements 1 are arranged in three stacked stacks 11, 12, 13 and a stack 11, 12 , 13 each comprise a transport plate 2 or base plate 2.

The three stacks 1 1, 12, 13 are arranged in three layers, wherein the first stack 13 is arranged in a first position on the pallet 14 such that in each case a first of the four outer sides of the base wall of the perimeter blocks on the transport surface 16 of the Pa - Let lette 14 come to rest. Also, one of the four outer sides of the transport plate 2 or the bottom plate 2 comes to lie on the transport surface 16 of the pallet 14. The second stack 12 is arranged in a second position on the first layer such that in each case one of the four outer sides of the base wall of the bead block elements 1 of the second layer come to lie on a respective second of the four outer sides of the bead block elements 1 of the first layer.

FIG. 3 shows a plan view of the upper side 1a of a known percolator block element 1. The percolator block element 1 has a base wall 17 with a square base surface, to which a plurality of hollow columns 183 are connected. The columns 18 may be formed conically with an oval cross section and have at the end facing away from the base wall 17 each have a column tip 19 (see Figure 4). A bead block element 1 has an axis symmetry of 180 ^° when rotating about a rotational symmetry axis of the base surface, the rotational symmetry axis extending perpendicular to the base surface of the base wall 17 and through the intersection of the two 45 ^° diagonals DU, DI2 of the base wall 17 goes. The pillars 18 are arranged to be relative to both centerlines M1, M2 of the base wall 17 mirror-symmetrically and with respect to both 45 ^° diagonals DU, DI2 of the base wall 17 are not arranged mirror-symmetrically. In the case of a reflection at the two 45 ^° diagonals D1 1, DI2 of the base wall 17, a column tip receptacle 20 or, at the position of a column tip receptacle 20, a column 18 comes to rest at the position of a column 18. The column tip receptacles 20 are provided in the structure 21 of the base wall 17 between the columns 18.

FIG. 4 shows a top view of the underside 1b of a bead block element 1, the hollow columns 18 extending perpendicularly away from the underside 1b of the base wall 17. The column tips 19 have a through opening 22 which allows passage of water through this opening 22 and the hollow columns 18.

FIGS. 3 and 4 illustrate that the column tip receptacles 20 and the columns 18 are designed and arranged in such a way that the column tips 19 of the upper bead block element 1 are inserted into the column tips when the block filter elements 1 are identical and rotated by 90 ^° about an axis of rotation. Receivers 20 of the lower Sickerblock- ckelements 1 can be introduced or that in two identical and identically aligned squaring blocks 1, the columns 18 of the upper Sickerblockelements 1 in the columns 18 of the lower Sickerblockelements 1 can be introduced.

FIG. 5 shows a side view of twenty block filter elements 1 stacked one inside the other. This stacking possibility results from the fact that the columns 18 of the percolating block elements 1 are designed and arranged such that, with identical and identically aligned infiltration blocks 1, the columns 18 of a percolating block element 1 arranged above can be introduced into the columns 18 of a percolating block element 1 arranged underneath , Between an underside 1 b of a base wall 17 arranged above and a top 1 a of a base wall 17 arranged therebelow, the illustration shows a stack spacing D1.

The sintered block elements 1 stacked one inside the other are arranged on a transport plate 2, which has feet 23 on its underside 2b, so that, for example, the fork of a fork-lift truck can be inserted under the transport plate 2. On the upper side 2a, the transport plate 2 recesses into which the column tips 19 of a Sickerblock- ckelements 1 can be introduced. Between the bottom 1b of the base wall 17 and the top 2a of the transport plate 2 results in a distance D2.

The square base can have a size of 80 cm x 80 cm. The columns 18 can have a length of 37.1 cm, starting from the upper side 1 a of the base wall 17. The column tip 19 may have a length of 1, 7 cm. The thickness of the base wall 17 may be 4 cm. Through the hollow columns, the block filter elements are stackable, wherein the stack spacing D1 of 2 cm between an underside 1 b of a first base wall 17 and a top 1 a of a second base wall 17 can be formed. Consequently it would be possible with a width of the pallet 14 of 80 cm, a stack of 32 Sickerblo- ckelementen 1 on the pallet 14 to arrange lying. A transport plate 2 or bottom plate 2 may have a thickness of 4 cm to protect the column tips 19 during transport. Such a stack 1 1, 12, 13 would have a length or height of 225.4 cm.

FIG. 6 shows a flowchart of a method for the transportable stacking of seepage block elements 1 on a sea container-suitable pallet 14.

Thereafter, in step 103, a horizontal arrangement of the one stack 1 1, 12, 13 or the plurality of stacks 1 1, 12, 13 takes place on the sea container-suitable pallet 14.

The horizontal arrangement 103 may include, in step 104, arranging the one stack 1 1, 12, 13 or the plurality of stacks 11, 12, 13 in a first position on the pallet 14 such that in each case a first of the four outer sides of the base wall 17 the bead block elements 1 come to lie on a transport surface 16 of the pallet 14.

In step 105, arranging remaining stacks 1 1, 12, 13 of the plurality of stacks 1 1, 12,

13 take place in a second position in such a way on the first layer, that in each case one of the four outer sides of the base wall 17 of the bead block elements 1 of the second layer come to lie on a respective second of the four outer sides of the bead block elements 1 of the first layer.

If further stacks 11, 12, 13 remain after step 105, they can be arranged correspondingly in a third, fourth, etc. position.

The step 101 of providing the one stack 1 1, 12, 13 or the plurality of stacks 11, 12, 13 may further comprise arranging 102 each of a transport plate 2 or a bottom plate 2 on the final percolating block element 1. The transport plate 2 or the base plate 2 may have feet 23.

In step 105, the one or more stacks 11, 12, 13 on the pallet can be secured

14 by means of securing means 15 done.

Figure 7 shows schematically, with regard to the bases of the percolating block elements, twelve transport units, ie the whole of the pallet and stacks, the different stacks each comprising a plurality of blocker block elements nested one inside the other and a final blocker block element. In the illustration, it is assumed that the rectangular base area corresponds in extent to two square base areas.

In the following, the indications "rectangular" and "square" refer to the base surface of the base wall of the respective block elements of a stack. "2x" refers to the fact that two such stacks are arranged in the respective layer.
