Furthermore, the invention relates to a transport container for plate-shaped insulating elements, in particular insulation boards, preferably mineral fibers, especially rock wool-containing packaging and / or transport units consisting of at least one, preferably two superimposed layers of insulating material and a preferably formed as a foil wrapping, in the the insulating elements are arranged in each layer so that they stand up on one of their, preferably extending in the longitudinal direction of the insulating elements narrow sides, and finally a method for producing a method for producing a packaging and / or transport unit for plate-shaped insulating elements, in particular insulation boards, preferably from Mineral fibers, in particular of rock wool, consisting of at least one, preferably two superimposed layers of insulating material elements and a preferably formed as a foil sheath, in the insulation elements are arranged in each layer such that they stand up on one of their, preferably in the longitudinal direction of the insulating material extending narrow sides.

Insulating materials are widely used in buildings and facilities. The sales volume of mineral wool insulation materials in Germany alone reaches the order of 15 to 20 million cubic meters per year. Insulation materials are light, voluminous and, despite high utility, inexpensive goods. Because of the large space requirements with comparatively low added value, trading companies limit the provision of insulation materials to a minimum. The manufacturers of insulating materials have therefore developed an advantageous logistics for the direct delivery of insulation materials on construction sites, produced on demand and in the name and on behalf of the trading company, the insulation materials are delivered on time to the hands of a processing company directly to the site. The insulation materials are provided in packaging and / or transport units, which are packages or packages of several packages with insulation elements, such as insulation boards or Dämmfilz -Rollen, which are therefore no longer stacked individually in the hold of a transport vehicle. Although it can be achieved with the individual arrangement of the insulating elements largely optimal utilization of the loading volume, but this advantage is economically aufzerrt by the labor-intensive loading and unloading of the transport vehicle. The combination of the insulation elements to palletized packaging and / or transport units allows fast and economical loading and unloading of transport vehicles.

The unloading conditions on construction sites or even in commercial enterprises are often not as favorable as with a manufacturer who can optimize the shipping of a single product.

To reduce labor costs, companies processing e.g. Produce flat roof seals, preferably large-sized and thus relatively heavy roof insulation panels that are put together to special packaging and / or transport units.

Since several companies with very different technical levels and corresponding differing economic interests are brought together in the logistics chain, it is of particular interest to the manufacturer of the insulating elements for various reasons, the costs for the distribution of the insulating elements to the end user to be as low as possible or to be involved in the possible creation of value.

Roof insulation panels made of mineral fibers have densities of about 100 to 200 kg / m ³ . There are also known roof insulation panels, which in a surface zone with about 180 to 220 kg / m ^{3 have} a significantly higher density than underlying arranged areas of the roof insulation panels. The highly compressed surface zone is intended to increase the rigidity of the roof insulation panels when walking. These roof insulation panels usually have thicknesses of about 30 - about 160 kg / m ³ . In a standard format of, for example, 1000 mm in length and 600 mm in width, the roof insulation panels are packed together by shrink-film wraps into packages of about 20 kg in weight and thicknesses of about 20 to 40 cm. Such packages are mostly shipped individually or stacked on wooden pallets.

Large-format roof insulation panels are produced, for example, with the dimensions 2 m long and 1.2 m wide and initially stacked. Such a stack of plates forms the basis for a packaging and / or transport unit. A well-proven in practice packaging and / or transport unit is in the DE 92 183 20 U1 described. The plate stack rests here on at least two support bodies, preferably of the same material as the roof insulation panels, the panel stack and the roof insulation panels being enveloped as a whole with a plastic film. The support bodies allow driving under the packaging and transport unit with pallet truck or a fork-type lifting device of forklifts.

The envelope consists of stretch films, preferably made of polyethylene. The film is wrapped in particular in the region of the support body several times around the plate stack to achieve greater transport safety. Stretch films have a good cohesion between the individual film layers. Due to the dimensions of the roof insulation panels, the relatively high weight of the individual roof insulation panels and the resulting frictional forces Overall, the plate stack already has a high internal rigidity and behaves essentially like a homogeneous block of mineral fibers. Favorable also has the effect that the roof insulation panels are separated on a production line across the initially endless fiber web. The roof insulation panels thus have in the longitudinal direction, which is thus transverse to the original manufacturing direction, a much higher internal rigidity and bending tensile strength, as in the direction of the plate width.

A packing and / or transport unit of such roof insulation panels thus has an overall weight of about 500 kg at an average height of the stack of 1.2 m and is not manageable without appropriate transport equipment, such as cranes, forklifts or the like.

In order not to overload the insulation elements locally, length and width of the support body are dimensioned so that neither the insulating elements nor the support body overloaded and thus damaged. The usually about 400 mm wide support body are arranged over the entire width of the plate stack. For example, the two meters long roof insulation panels collar on both ends about 150 mm, but preferably 200 mm above; in the middle remains an approximately 800 mm wide gap.

The packing and / or transport units are assembled at the manufacturer for transport or storage at the manufacturer or on the construction site. The transport to the construction site or to a warehouse of a manufacturing company or a trading company is usually done by truck. Because of the greater flexibility, lorries with overplated flatbeds or superimposed swap bodies are predominantly used. The packaging and / or transport units are mounted by means of forklifts from both sides on the bed of the truck or a trailer, wherein no more than two packing and / or transport units are arranged one above the other. Already during loading, the tarpaulins must be on both sides of the truck and / or of the trailer are unfolded. For this purpose, the numerous lateral brackets of the over-planning must be opened and half of the tarpaulin with the help of boards or the like folded up and stored on the scaffold.

The same process occurs in reverse order in the warehouse of a trading company or on a construction site. If the transportation of the transport unit takes place there directly on the roof surface with the aid of tower cranes, the tarpaulin must be largely removed. Otherwise, the transport units are unloaded by means of forklifts and temporarily stored. In both cases, the discharge process is delayed and thus more expensive.

In order to avoid a concentration of loads in the catchment area of the crane and thus possible deformations of flexible roof shells made of profile sheets, for example, the packaging and / or transport units are immediately distributed on a supporting roof shell. Serve multiaxial pallet truck, which can be moved easily on roof shells even under load.

Such favorable circumstances are but rarely encountered on construction sites. Due to the fact that many works simultaneously on a building to be erected and the material deliveries triggered by them, bottlenecks regularly occur in the use of the available crane capacities. The delivered insulation elements must therefore be stored temporarily. The same situation arises naturally when cranes are placed for transporting the insulating elements only temporarily and larger amounts of insulating elements to be lifted in one go on the roof surface. For this purpose, the packaging and / or transport units are lifted by means of normal forklifts from the back of the truck and / or the trailer. The usual fork width is outside about 0.6 m. Each fork is about 1.4 m long and only about 0.10 m wide. The usual material thickness is in the range of approx. 40 mm.

The fork is driven centrally under the stack of plates, although this is not always possible in the often uneven terrain in the construction site, so that the wrapper is exposed together with the support body possible damage by the forks of the lift truck. These damages affect the intended future use of the support body as insulating material to be processed. Furthermore, in the careless driving under of closely behind or next to each other parked on the bed of the truck packaging and / or transport units and the subsequent lifting of the packaging and / or transport unit, the adjacent packaging and / or transport unit may be damaged.

The specific loads on the bottom of the plate stack insulation element by the forks is often too large for insulation elements with high weight and regularly leads to damage to the insulation elements in the range of fork supports. These areas are then damaged in such a way that they lead to defective Dämmergebnissen and must be separated from the large-sized insulation elements, in particular roof insulation panels. When handling the packaging and transport units with cranes the same non-material-compliant attachment technique is used regularly. The plate stacks are lifted, for example, with crane hooks, as they are common for the transport of wooden pallets. Again, the specific bearing surface is much too small for compared to boards or panels made of wood materials much deformable Dämmstoffelementen. Further damage to the insulation elements is caused by lifting the plate stack with ropes or narrow straps.

When handling the packing and / or transport unit with a lift truck, the fork should be placed centrally under the stack of plates. As a result, the arranged in the plate stack insulation elements are subjected to considerable bending, with the upper zones of the insulation elements are claimed to train. In a frontal lifting to Transporting the plate stack on the roof surface, however, moves the tension zone downwards. These strong stresses in alternating directions, as well as occurring during transport of the packaging and / or transport unit dynamic forces are to be considered in the design of the envelope or the arrangement of the insulating elements.

Other packaging and / or transport units for plate-shaped insulating elements are from the EP 0 962 399 A2 known. A packaging according to the preamble of claim 1 is disclosed. In this prior art packaging, the insulation panels of mineral fibers are arranged in two superimposed layers within a sheath, the insulation boards stand up on one of their running in the longitudinal direction of the insulation boards narrow sides. It is a small container, which should be suspended in the frame area in corresponding devices and therefore has a carrying tab.

Furthermore, from the DE 297 15 125 U1 a comparable transport packaging for large-volume lightweight building materials, especially insulation materials known, which is also a small package, which should be handled by appropriate handles in a simple manner.

From the DE 40 26 807 A1 is a packing unit made of mineral wool plates with a sheath known, which consists of a shrinkable plastic film and the ends are joined together by a weld, wherein at the weld an outwardly facing carrying tab is flanged. Visible this is again a small container for handling, for example, on a scaffold or a simple sale and transport in hardware stores and other specialty stores to so-called do-it-yourself craftsmen.

However, these prior art packaging and / or transport units are only partially suitable for the economic transport of larger quantities of plate-shaped insulating elements. Especially in the construction site area, but also in the field of construction site dealers is associated with these packaging and / or transport units a complex packaging system and a complex loading and unloading of the vehicles.

Based on this prior art, the present invention seeks to provide a packaging and / or transport unit and / or a transport container and / or a method for producing this packaging and / or transport unit, in which or at a high Stability are given both during transport and in handling on a construction site and at the same time a more economic, since cost-effective transport is possible.

The solution to this problem provides for a packaging and / or transport unit according to the invention that the surrounded by the film insulating elements are arranged with their narrow sides with interposition of the film on support bodies, which are arranged substantially perpendicular to the longitudinal extent of the insulating elements and via connecting elements with the insulating elements and the film are connected. On the part of the transport package is provided to solve the task that several packaging and / or transport units are summarized and surrounded by a film and arranged on at least one support body. Finally, a method is provided for solving the problem, several insulating elements are placed close to each other on one of their longitudinal narrow sides, the insulating elements are compressed by a pressure on their large surfaces, the compressed insulation elements are wrapped with a film and finally in the film arranged insulating elements are connected to support bodies, which are arranged transversely to the longitudinal extent of the insulating elements with the interposition of the film in the region of the upstanding narrow sides.

Further features and advantageous developments of the invention will become apparent from the subclaims and from the following description of the advantages of the individual further developing features.

According to the invention it is thus provided that the insulating material elements are arranged in the film such that they stand up with their narrow sides on support bodies. As a result, the possibility is achieved to arrange a large number of insulating elements in a packaging and / or transport unit, since it does not depend on good manageability by a person. Rather, the packaging and / or transport unit according to the invention should be manageable with machines, i. For example, with lifting devices can be placed on a truck or lifted from this.

By setting up the insulating elements on a narrow side is achieved on the one hand, that the flexural rigidity of such a stack or more so formed and arranged in layers stack is sufficiently high to form a stable packaging and / or transport unit with relatively little use of packaging materials , which can be handled both with forklifts, as well as with cranes, so that a simple loading and unloading of transport vehicles, especially those that are designed to be open, is possible.

In this way, insulation elements in the form of large-sized insulation boards with small thicknesses can be combined to form stable packaging and / or transport units.

Preferably, the insulating elements are placed under compression on their large surfaces in the film. For this purpose, it is provided, for example, that the insulating elements are arranged side by side on their narrow sides in a first step, before then acting on both sides of a stack thus formed a pressure plate on the free large surface of the respective outer insulating elements and compresses the stack. Subsequently, the sheathing of the thus compressed and compressed stack of the insulating elements is carried out with a shrink film. The compression plates holding the stack up to the jacket are then pulled out of the jacket, whereupon the shrink film can subsequently be shrunk by a thermal treatment. The support body can be arranged directly inside the film. But it is also possible to subsequently attach the support body outside the film with more film strips or a change. In any case, results in a total stable packaging and / or transport unit for plate-shaped insulating elements.

Lightweight insulating elements made of mineral fibers have densities of about 22 to 50 kg / m ³ when produced from stone fibers and about 12 to 35 kg / m ³ when manufactured from glass fibers. These insulating elements are easy to compress even with low forces. However, this also results in a low compressive strength and rigidity of such insulation elements.

If such insulating elements are combined into stacks, the result is an unstable and very soft structure. In order to save transport and storage space, the insulating elements can be compressed. Compressed insulating elements or packages of compressed insulating elements are inherently stiff and do not have the disadvantages described above. The disadvantage, however, is that a stack of such insulating elements can not be compressed homogeneously. Rather, the compression and reaction force acts almost exclusively on the outer plates, which are permanently deformed, while the inner insulating elements remain largely uncompressed.

If such lightweight insulation elements combined to form packaging and / or transport units and wrapped with a film, so form the packaging and / or transport units no rectilinearly limited side surfaces. A summary of these packaging and / or transport units to Transportgebinden leads due to the slightly convex side surfaces to stability problems of the container. Such transport containers are primarily used for transport from the manufacturer to a trading company, where the transport container usually turned off and the content is sold in individual packaging and / or transport units. If necessary, the packaging and / or transport units are opened and individual insulation elements offered and sold.

The requirements for the stability and durability of support bodies used in such transport packaging is less here than on a construction site. As a result, it is possible here to use support bodies made of unfolded cardboard or of paperboard, which are optionally reinforced with stiffening plastic structures or rigid foam panels, as well as composite constructions of such materials. It has proven to be advantageous to use instead of these materials support body, which consist of highly compacted rock wool, especially from rock wool slats, as this produces no further packaging material, which makes an additional recycling process or a supplementary disposal path necessary. In addition, such support body are sufficiently stable to carry a corresponding transport container for a long time.

As already stated, the packaging and / or transport units have a slightly spherical shape due to the resilience of the compressed insulating elements and the lack of dimensional stability of the film. By a corresponding external pressure, this spherical deformation can be reduced. However, the non-compressed side surfaces, thus the narrow sides of the insulating elements form a total of a smooth bearing surface. It is therefore advantageous to design the transport containers such that the packaging and / or transport units are arranged standing one above the other on their narrow sides.

As an alternative to the above-described methods, the insulating material elements are wrapped in the film under compression on their large surfaces in such a way that the insulating material elements are introduced into the film together with the support bodies in one operation. The length of the support body corresponds to the width of the compacted insulating elements. The ends of the support bodies are angled in accordance with the material.

Subsequently, the insulating elements are compressed together with the sheath and the support body. The ends of the film forming the sheath are welded together, glued, riveted, clamped and / or sewn. A centrally arranged frictional band increases the strength and rigidity of the packaging and / or transport unit.

The compression of the insulating element is not carried out in this embodiment by corresponding pressure plates which act on large surfaces of the outer insulating elements, but by a negative pressure. For this purpose, the insulating elements are surrounded by the enclosure, the enclosure closed and evacuated from the enclosure, the air. Finally, the opening for evacuating the air is welded, so that the insulating elements are arranged under compression in the enclosure. By applying the negative pressure, a gentle compression of the entire insulation elements is achieved.

The films commonly used are relatively smooth and therefore have only low coefficients of friction. The inner movements of the insulating elements therefore preferably take place on these sliding surfaces of the films. To complicate these movements and thus avoid falling out of the packaging and / or transport unit or to keep the previously required contact pressure because of the associated risk of permanent deformation of the insulating elements as low as possible, the bearing surfaces of the films are provided with double adhesive tape or impregnated by slow-acting adhesive sprays. Through this inner Stiffening, the strength and amount of the envelope or the film can be significantly reduced.

Alternatively, it can be provided that tensile inserts are arranged between the insulating elements or the packaging and / or transport units of a transport package. These tensile inserts can also be provided as cover layers below the film of a packaging and / or transport unit or a transport container.

The packaging and / or transport unit is placed on support bodies whose flanks are angled in accordance with the material. Between the insulating elements and the support bodies, an intermediate layer is inserted, which is formed in area larger than the surface of the erected insulating elements. The projecting beyond the insulating elements area of the intermediate layer are angled upwards to increase the absorbable tensile force. A comparable intermediate layer is placed on the position of the insulating elements below the sheath. In this area, the protruding beyond the insulating elements areas of the intermediate layer are bent downwards. Finally, an intermediate layer may additionally be arranged between the insulating elements or adjacent packaging and / or transport units, in which case the areas of the intermediate layer projecting beyond the insulating elements are alternately bent upwards and downwards.

An alternative embodiment provides that between the insulation elements, a tear-resistant film is arranged, which runs meandering between adjacent insulating elements. Of course, the same applies to a transport container, in which case the tear-resistant film is laid meandering around the individual packaging and / or transport units. The stability of a transport package formed in this way or of a packaging and / or transport unit formed in this way can be sustainably increased by virtue of the fact that the ends of the meandering film are frictionally engaged with one another be connected and thus result in a complete sheathing of the insulating elements or the packaging and / or transport units.

Finally, in addition to the transverse to the longitudinal direction of the insulating material sheath enclosing a sheath in the longitudinal direction may be provided to completely pack the insulation elements and protect against the weather. The same applies with regard to a transport package according to the invention.
