Abstract

In a transport unit (1) for rock wool products (2) arranged in a stack, the stack has on its principal surfaces receptacles (5) for handling by mechanical means of transport, such as fork-lift trucks, lifting equipment and the like.

Description

The invention relates to a transport unit for mineral wool product arranged in the stack te, especially mineral wool insulation boards.

Such insulation boards are essential for the construction industry, especially for Roof insulation and facade insulation and the like used more. For the purpose of Such insulation boards made of mineral wool are transported and stored in a stack arranged in which the insulation boards usually with respect to their main surfaces be arranged one another. For stabilization, such stacks are made from one another arranged insulation boards very often covered with foil, which also serves as a weather protection and protection against transport-related damage is provided.

The main problem with the transport and storage of insulation products made of mineral wool is that these are products with a comparatively large volume, which can also have a relatively high weight. For example, insulation boards are offered in raw density ranges from 10 kg / m ³ to 200 kg / m ³ with an area size of up to 2000 by 1200 mm in thicknesses of, for example, 50 mm to 200 mm, so that transport units with considerable stacked arrangement of such boards Dimensions arise, which leads to a corresponding space for transport and storage. Just the size and weight of such transport units are hardly manageable manually, rather mechanical transport means must be used, such as forklifts and the like.

Since the insulation market is mindful of the fact that significant amounts of insulation per Year alone in the Federal Republic of Germany, also very intensive of Competitors are served, there is inevitably a significant price pressure that this leads to transport units having to be optimized from all points of view. This also means that the transport units must be packed or designed so that them from usual means of transport, especially forklifts, without the risk of loading damage can be handled.

Such stacks of insulating boards are usually used on wooden pallets Arranged for transport and storage purposes, which was well handled by forklifts can have, but have the disadvantage that they are used for the return of empties port are heavy and voluminous and are also relatively expensive. For this Efforts are being made in the insulation industry, substitutes for these are used to develop pallets that facilitate recycling and, in particular, recycling enable.

In this context, it is already known (DE-A 42 18 354) to include a transport unit form, in which the stack of stacked insulation boards on a support body pern is stored, which are formed from a material that can be used for insulation purposes. Support body and insulation panels are here together by turning one Foil connected to a transport unit. Due to a staggered arrangement of the edition body underneath the stack, there are free spaces or receptacles for the intervention of Lifting devices for mechanical means of transport, such as forks on forklifts. However, these transport units carry the risk that, as a result of damage the film wrapping in the area of the support body when handling by me Chanish means of transport then forcibly the film wrapping of the stack as a whole can be damaged, which then the stabilizer essential for transport and storage  stack is endangered and, especially during transport, a disintegration of the stack is possible. This problem also occurs with transport units according to DE-U 296 20 646 where the stack of damping plates is supported by support bodies and the entirety of the stack and the support body are encased by a film. In the rough Operation when handling such large transport units using mechanical trans However, port means can very often cause damage in the area of the support body the film wrapping, such as an incision, tear and the like, which is not necessarily immediately leads to damage to the film envelope as a whole, depending but if it is transported further by further tearing to damage the film cover can result in total with the harmful consequences as described above.

Finally, to prevent this risk of damage to the shell as a whole, it is known (DE-A 198 42 721), a transport unit from a stack of one another tidy insulation boards to create, in which the stack as a whole by means of a film is enveloped, but not the support body are included. However, these are from egg made of a material suitable for insulation purposes. The support body are included glued to the bottom bottom surface of the stack. But it was considered necessary see, specifically with a view to achieving stable containers, the individual to insulate nen insulation boards within the stack by an adhesive connection bind, which, however, involves additional effort. Another disadvantage is note that the hot melt adhesive commonly used in this context can easily penetrate into the surface of mineral wool insulation panels where by in turn, especially with excessive adhesive application, the properties of the Insulation product can be negatively affected. This is particularly the case with insulation Fabric panels are disadvantageous where special fire resistance is required. Also the Applying the adhesive to the insulation boards considering the bond is under the disadvantages of rational production.

The object of the invention is to provide a transport unit for mineral wool products, in particular Insulation boards, to create that particularly well on the criterion of manageability is adapted by means of mechanical means of transport, with main focus also on it is laid that as little waste material as possible should be created for environmental reasons.  

It is also necessary that such a further developed transport unit to the la tent price pressure in the insulation sector, so it is comparatively uncomplicated adorns in construction and is inexpensive.

This object is achieved by the characterizing part of claim 1 Features included solved, expedient training through the in the sub features contained claims are marked.

According to the invention, the stack of insulating material arranged one above the other plates, which is preferably wholly or partially covered with a shell, recordings for handling by mechanical means of transport on at least one of the main surfaces of the stack.

These recordings can be designed in different ways. So it is especially for transport in harsh environments and with voluminous stacks, especially ge weight heavy stacks expedient, the recordings through recesses one Form slat plate, which is arranged as a carrier of the stack below the stack. The lamellar plate is characterized by the special fiber due to the manufacturing process direction essentially perpendicular to the main surface due to increased compressive strength, see above that a carrier in the form of a lamella plate is very suitable for the application mentioned well suited. Since the lamella plate is also made of mineral wool and in particular Can be formed uniformly with the insulation boards, such is suitable Beams also for use as insulation on site, i.e. on the construction site. In this case return as empties is no longer required. As a result of the rigid construction Such a carrier, which is constructed in particular in a pallet-like manner, can form the slat plate can also be used as a reusable means of transport and is therefore common used. It is particularly advantageous here that such a lamella plate carrier is closed a roll can be wound, which for the return of the empties Advantage is. The recordings within a lamella plate can thereby be formed be that slat elements with different slat lengths are used, so that recesses are formed by recesses, which are the recordings for the Form means of transport.  

According to a further embodiment, the stack is covered with a fabric web, which is preferably designed tensile, such as a polyethylene fabric web and in which the the tabs forming the receptacles are formed. The training can take place integrally, d. H. the tabs can be made of the same material with the fabric web. You can NEN alternatively, however, also put on and welded, glued, or to the fabric web otherwise be connected. The tabs that hold the mecha African means of transport can be stiffened for easy access by enable retracting fork tines without the tabs being kept open separately Need to become. Such stiffening can be done, for example, by embedding git ter-like stiffening nets and the like. In the tabs.

In a further training, the tabs can be made with strips of mineral wool insulation be filled, which also serve as mold cores in the case of a one-piece design of the tabs can be used with the fabric web. These can be removed from the tabs Strips of mineral wool insulation can be used on site to support the stack become. This is particularly advantageous for a transport unit in which the tabs are open the top surface of the stack are formed or arranged, because then the Possibility to place the stack on the strip removed from the tabs to be stored, which are then arranged below the stack. If necessary, they can come here removable strips can be coated with an adhesive or adhesive, which with a peelable film is covered. Conveniently, the packing that the La fill out, be provided with a delayed activation of the adhesive layer, which is activated in particular when this packing is used as a carrier for the stack should be used.

In a further, very advantageous embodiment of the invention, in which the carrier is identical to the material of the insulating wool of the stack, is the Carrier preferably formed itself as an insulation board, which is used for protection against weather influences is expediently surrounded with a plastic film. Because insulation boards are offered in specific standard dimensions for specific applications, where, for example, the insulation boards are graded with the same length  Widths and thicknesses are offered, the carrier is preferably the same standard type as the insulation board, but with a smaller standard width, so that with a central arrangement the recesses for the mechanical means of transport on the side of the insulation board are limited. This embodiment is particularly suitable for pallet stacks for insulation flat roofs. The transport units are opened using a lifting device the roof is hoisted, where the insulation panels are then unpacked. Since the carrier as Insulation board comes from the same series of board types, the carrier can at the same time Insulate wake on the roof to be used. In this case there would be pallet waste attributed only to the film envelope, which the carrier in the form as an insulation board around wraps so that it cannot be used for other purposes on the building. With this con The transport unit can thus be processed on site at the construction site become. It would then only be the packaging envelopes of the stack, what but so far has been the case.

In further training, the insulation board coming from the same type series ten, which are used as a carrier, are also arranged in the region of the edges of the stack the, so that depending on the staggered arrangement, there are two lateral outlets to the edges recesses and between the two carriers a central recess for the intervention of the mechanical means of transport. It is useful if an adhesive Bund or adhesive bond between the carrier and the bottom of the stack is created. This can done by an activatable adhesive, for which purpose the insulation material plate surrounding film sleeve of the carrier is provided with an adhesive layer with a peelable film is covered. This creates a firm bond between the carrier and the stack ensures and at the same time prevents the adhesive from affecting the insulation behavior of the Carrier, which can also be used for insulation purposes.

In a further training, the supports are support bodies, which are made of system-inherent components are formed, in particular about foil wraps, the foil being about a sealing foil can be used for sealing purposes. But the carriers are useful also formed from packing elements, the other additional components, such as dowels, screws ben and the like and are packed so tightly that the support body ent are designed to be pressure-resistant for the property as a carrier of the plate stack. Also  The advantage here is that the transport unit is used on the construction site as a whole can be, which leads to a significant reduction in waste on construction sites.

According to a further expedient concept of the invention, the stack is the transport unit by corner profiles arranged at the four lower corners, which the Trä form ger and at the same time serve as edge protection. These carriers have a reusable function, can be reused as often as you like. They are preferably made of plastic, so that they are easy to manufacture and can be cleaned well. To improve the hold the corner profiles can be connected to each other crosswise by struts. If the struts arranged crosswise are connected to each other in the middle by a joint, this carrier device can be scissor-like together very well for the return fold so that the transport volume for the return of empties is considerably minimized can be.

Fig. 7 shows a further embodiment of a transport unit in which the stack of insulating boards made of mineral wool is supported by corner elements made of plastic and

Fig. 8 is a perspective view of the corner element, wherein all figures are kept in a purely schematic representation.

In the transport unit shown in FIG. 1, generally designated 1 , a stack of insulating boards 2 made of mineral wool arranged one above the other is encased with a film 3 and received on a carrier 4 in a pallet-like configuration. The films of wrapping of the stack of FIG. 1 envelopes the stack of insulation panels 2 at only 4 peripheral sides, but leaves the two end faces free, of which in the front view is visible. Of course, alternatively, a film packaging can also be seen in which the end faces can also be completely covered with film or only partially in the outer areas when using a shrink film.

A plastic film, for example a heat-shrink film, is particularly suitable as the film however, a packaging made of a film is expedient, in which the ends overlap beaten and connected by gluing, welding or the like. Here it is from Case by case also useful to un compression the stack of insulation panels then pull the film over so that the finished film wrapping is relieved due to the resilient properties of the previously compressed insulation boards is excited. However, since the invention is not actually related to the type of wrapping Senses concerned, needs here on the different ways of wrapping a sta pels with a film, e.g. B. also with a foil color and the like. Who did not go into detail the. The purpose of the wrapping is to hold the stacked ones together Insulation boards for transport and storage and as protection against the insulation boards Weather influences as well as against damage and the like. Furthermore, the modular enables  term wrapping of a stack of insulation boards also the stacking meh rerer this stack to obtain a so-called large container.

The carrier 4 is constructed in the exemplary embodiment shown by a pallet-like structure from lamella pieces with different lamella lengths, so that receptacles 5 result which can be used for the engagement of mechanical transport means, in particular tines of forklifts.

For this purpose, the carrier 4 is constructed, for example, from three lamella elements 6 with the same lamella length, between which lamella elements 7 with a shorter lamella length are arranged. This results in corresponding recesses compared to the footprint of the longer slat members 6 through which the recesses 5 for the engagement of the transport means are limited.

The lamellar plates are comparatively pressure-resistant structures due to the special fiber orientation. In conventional insulation boards, the fibers are oriented essentially in the longitudinal direction of the two main surfaces, essentially due to the manufacturing process of the mineral wool insulation boards, so the fiber orientation of the known lamella boards is mainly perpendicular to the two main surfaces, resulting in an increased compressive rigidity the insulation board with fibers parallel to the main surfaces results. The manufacture of such lamella panels is carried out by cutting lamellar blocks from conventional len insulation boards, which are then turned by 90 ° and attached to a flat support material such as aluminum foil or glass or plastic fabric by gluing to form the lamella plate. In Fig. 1, the lamination is designated 8 and consists of a fabric-reinforced aluminum foil. This forms, so to speak, the upper wing of the carrier 4 , on which the stack of insulating boards 2 is arranged and at the same time serves as a barrier to possible rising damp.

Although the carrier 4 constructed from lamellar plates 6 and 7 is a pressure-rigid pallet-like plate, it can be rolled up into a wrap after use without any problems, which facilitates the return transport of the empties pallet.

Of course, it is also possible that from Fig. 1 apparent pallet-like support plate made of only two edges arranged longer lamella plates 6 to create, between them, due to the recessed lamellar panel 7, a recess 5, which is used for the access of the tines of the forklift bil the , However, the central arrangement of the further lamella plate 6 offers a more stable structure, which prevents the carrier plate 4 from bending in the interior. This is particularly useful in connection with high stacks, which are made up of a plurality of stacked insulation boards and for stacks with very large insulation sheets.

Particularly when the transport unit is used in areas where bad weather conditions prevail, the pallet-like carrier 4 can be wrapped with a film, so that even if the transport unit is parked on wet terrain or is exposed to rain, a correspondingly long operating time the multi-way pallet carrier 4 is guaranteed. It is also possible to treat the carrier 4 with water-repellent agents, so that it is resistant to water, which can occur in the form of peaks on site at the building.

In the embodiment according to FIG. 2, the stack of insulating boards 2 arranged one above the other, which are usually in rectangular form with a rectangular cross section, is covered with a fabric web which is either only provided over the circumference or also covers the two exposed end faces. The fabric web denoted by 9 is designed to be tensile in this embodiment and preferably made from polyethylene, since in this embodiment the receptacles 5 for the means of transport are formed by tabs 10 arranged above the stack, so that when the stack is lifted, forces exerted on it Tabs 10 are introduced into the fabric web 9 . In the La's 10 , it can be elements that are separately manufactured and attached to the upper deck surface of the fabric sheet 9 , something by welding or gluing, but advantageously the tabs 10 are integrally ausgebil det with the fabric sheet 9 and therefore also of the same material , The one-piece production can take place, for example, in that when the stack is wrapped with the fabric web 9, corresponding cores with the dimensions of the later recesses 5 are placed in order to form the loops 10 . The cores can then be removed again, so that the tabs 10, which are open on both sides, remain for the engagement of the tines of a forklift. A correspondingly rigid design of the tabs 10 ensures that the tabs 10 remain dimensionally stable, ie do not coincide in the area of the recesses 5 .

A modification of the embodiment according to FIG. 2 is shown in FIG. 3, two functional positions being shown here in a drawing. To form the plate stack, the stack is encased with a fabric web 9, specifically analogous to the embodiment according to FIG. 2, with tabs 10 again being provided in the upper region. In this embodiment, however, the tabs 10 are filled with strips 11 of mineral wool insulation material, which so to speak form or can form the cores for forming the recesses 5 or the tabs 10 . It is preferred that the strips 11 are made of the same material as the insulation boards, which has the advantage that the strips can then be used for insulation purposes with the intended use of the insulation boards of the stack on site, i.e. at the construction site ,

In the event that the stack is to be handled by a mechanical means of transport, for example a forklift, the insulation strips 11 only need to be removed on site. It is possible to use the insulation strips 11 as a carrier 4 , as illustrated in the lower functional illustration in Fig. 3, the Trä ger here by the strips 11 removed from the tabs 10 are formed of insulation. For the purpose of stability, an adhesive connection 12 is provided between the top of the insulation strip 11 and the bottom of the plate stack. This bonded bond can already be prepared, for example, in which the insulation strips 11 stored as cores within the tabs 10 are provided with an adhesive layer, which are covered on the outside by a removable strip of film.

In the embodiment according to FIG. 4, in which in turn a stack of insulating boards 2 is encased by means of a fabric web or film 3 , a material-uniform element with the insulating boards 2 packed in the transport unit is used as the carrier 4 , namely a corresponding strip with a smaller width 4 as the frontal longitudinal extent of the insulation panels 2 shown in FIG. 4. As a result, receptacles 5 for engaging the mechanical means of transport are limited or created on the left and right below the stack. This embodiment offers the advantage that the insulating element or insulating material plate 13 which makes up the carrier 4 and has a smaller width can also be used on site for insulating purposes. In this embodiment according to FIG. 4 it may also be expedient to wrap the carrier with a film 14 in order to make the carrier weatherproof. This is particularly advantageous in view of the soil moisture, which is often caused by rain, which could otherwise damage the carrier 4 according to the invention.

A modified embodiment is shown in FIG. 5. Here, too, the trans port unit 1 comprises a stack of insulating boards 2 arranged one above the other, which are surrounded by a film envelope 3 , the carrier 4 being formed here by two insulating boards 13 , which in turn are expediently of the same material or identical to the insulating boards 2 within the stack , It is preferred that the carriers 4 are elements which, like the insulation panels 2 , are guided within the stack in standard dimensions. For example, the stack could be made of insulation boards 2 with a length and width of 2000 × 1200 mm, but the insulation boards 13 could be designed for standard size 625 × 1200, which has the consequence that the insulation boards 13 are flush with the stack as a carrier can be aimed and limit the desired recesses 5 as recordings due to the reduced dimensions. In the embodiment according to FIG. 5, 3 receptacles are identified purely schematically, this being dependent solely on the arrangement of the insulation panels 13 below the stack. Depending on the type of mechanical means of transport to be used, the insulation panels 13 can be offset more or less far from the outer lower edge of the stack, designated by 15 .

Also in the embodiment of Fig. 5, it is expedient if the insulating boards 13 are wrapped as a support in view of weather protection with a foil 14, whereby also here a pressure-sensitive or adhesive composite analog of the embodiment of Fig. 3 can be easily seen. This is designated by the same reference number 12 . An advantage of the embodiment of FIG. 5 is that the insulation sheets 13 , which are present in an adapted standard for the insulation boards in the stack, can advantageously be used on site at the construction site at the same time as the insulation boards for insulation purposes. It only needs to be removed in the case of protection against weather conditions provided film 14 , which in turn should have a greater thickness than the film cover 3 to meet the more difficult transport conditions in the floor area.

According to the embodiment of FIG. 6, again a stack of insulating boards arranged one above the other, wrapped with a film or the like, is received on two supports 4 , which are arranged below the stack and are preferably bonded together in such a way that corresponding receptacles 5 for inside or outside limit the mechanical engagement of lifting elements of means of transport. In the case of the embodiment according to FIG. 6, the supports 4 are formed by components which are inherent in the system and which can expediently be used at the construction site in connection with the insulation boards delivered in the stack.

If, for example, insulation boards are used in the transport unit shown in FIG. 6 for the insulation of pitched roofs, then the supports 4 are expediently formed by film windings, in which plastic film is wound around a stable core, such as a tube, the film therein as underlayment and the like or can be used as a cover sheet. This means that an additive, which is required anyway when laying the insulation boards, can be transported to the roof at the same time as the transport unit, so that the transport unit contains both the insulation boards and the required film at the same time in one package. Depending on the application, the support 4 may be structures that are made, for example, from Abdichtungfo lines or packs that may contain nails, screws or dowels and other additional components for the insulation purpose or the construction purpose. Depending on the type of additional components, the carrier 4 can only extend in its length over a partial section of the width of the stack, so that a total of 4 carriers are arranged below the stack for the possibility of access from both sides by a means of transport. However, the carriers 4 can also extend over the entire width of the stack, as is particularly expedient in the case of the previous embodiments, so that they are essentially flush with the stack edges.

In the embodiment according to FIG. 7, the carriers 4 are designed as corner elements 16 , which are preferably made of plastic and thus form reusable elements and at the same time serve to protect the edges of the stack. Such corner elements 16 are preferably suitably designed as edge protection elements and support elements. In the illustrated exemplary embodiment, which in turn is shown in FIG. 8 in the schematic representation of a perspective, the corner element 16 is formed with two side surfaces and a bottom surface, where the bottom surface is provided with projections 17 , which can be designed as nose-like projections or knobs. For better clarification, the corner region of the stack, which is received by the corner protection element 16 , is indicated by a dashed line in a schematic representation. The corner protection elements can be fixed by means of an adhesive bond. However, it is also expedient if the corner elements 16 are connected to one another via a cross-like carrier. According to the projecting lugs 17 here limit an inner recess 5 , which in turn can NEN for the engagement of the means of transport.
