Abstract

The transporting unit comprises plates (2-7) which are particularly of rock wool, the mineral fibres running parallel to their large surfaces. These are assembled in the upright position and close together in a stack, forming one or more recesses (8) for engagement by lifting forks, etc.. The stack is held firmly and permanently together and under tension by a wrapping sheet (9) enclosing all its vertical sides. The outer plates at both sides of the stack can be of greater height than those between them and which are offset from them, so that the outer ones form supporting feet extending below the inner ones.

Description

The invention relates to a transport unit, consisting of a number of mineral wool panels, preferred wise stone wool slabs.

Transport units from a plurality of one each Stack of assigned insulation boards are from the DE 42 18 354 A1 known. With these transport units the problem was in the foreground, the most common in the past wooden pallets that are suitable for the use of Avoid forklifts were required. At the out the laid-open transport units are Support body provided, which from a for insulation purposes usable material exist. On these support bodies are stacked of insulation boards, the insulation panels are essentially horizontal. Before trains exist both the support body and the insulation mineral wool panels. The fibers within the Insulation boards are essentially parallel to the large surfaces of the insulation boards oriented, ver run essentially horizontally. With this fiber The insulation boards have only one orientation Inherently low compressive strength perpendicular to the large ones Surfaces. The advantage of this well-known transport stone units is that the respective plate stack by means of common films with the support bodies to one compact unit is connected that this transport unit without any pallets or without further transport pack can be transported using conventional forklifts can and the entire material of the transport unit on the Construction site can be processed for insulation purposes.

In contrast, the invention is based on the object to create a transport unit in which the previously mentioned support body can be avoided and nevertheless a transport by forklift or other Funding is possible, with which in particular internal transport, e.g. B. from manufacturing road to the camp, is made easier and harmless numerous transport units for warehousing are stackable.

Transport is used to solve the task proposed unit consisting of a number Mineral wool slabs, preferably rock wool slabs, in which the mineral fibers essentially parallel to the large plate surfaces run and which one Plate stack with vertical position of the plates tight are arranged side by side such that at least one Cavity formed for the engagement of a means of transport is, with the stack of plates vertically at least on all len circumferential sides under tension through a foil winding is firmly and immovably connected.

The fact that the plates within the transport unit stand vertically and the mineral fibers essentially parallel to the large plate surfaces, thus also run essentially vertically, there is a large one Compressive strength perpendicular to the surface of the transport unit, so that very many transport units one above the other can be stacked. Through the live under tension brought foil wrapping results in a compact unit, within which the individual plates do not oppose each other can move or slip together.

Advantageous configurations of this transport unit result from subclaims 2 to 13.  

Alternatively, one is used to solve the task Proposed transport unit consisting of a number Mineral wool slabs, preferably rock wool slabs, in which the mineral fibers essentially parallel to the large plate surfaces run and which one Plate stack with vertical position of the plates tight are arranged side by side, whereby on the lower and / or top of the plate stack stiffening elements are provided on which cantilever elements for the hanging Attack transport of the plate stack and taking the Plates of the plate stack at least through a foil wrapping around all outer vertical surfaces of the panel stacks are pressed together.

Before going into the individual embodiments general explanations are first cleverly.

All of the exemplary embodiments explained below is common that the mineral wool slabs, preferably stone wool panels, or more generally, all insulation sheets of material, vertical or inside the transport unit upright to a stack of plates close together are arranged. Because the mineral fibers are essentially parallel run to the large plate surfaces, with vertical ones The position of the plates is also at least in part run vertically, the pressure is much higher strengths perpendicular to the small areas of the panels and thus perpendicular to the top of the transport unit than to the large plate surfaces. The ratio of directional compressive strengths - always at 10% Deformation determined - at high bulk densities the  Plate material about 1: 1.5 and increases at medium to low bulk densities down to about 1: <4. The Deformation is therefore when pressure is exerted on the large surfaces 1.5 to <4 times larger than with pressure on the small areas of mineral wool slabs. It is understood that the ratio but also on the type, shape and other Properties of the mineral fibers as well as the type and quantity of the binder used are dependent. A sure one manageable transport unit can easily by Experiments with appropriate plates are developed, and adapted to the respective purpose, such as height or number of stacked transport stones units. For example at a maximum stack height in the usual means of transport, such as trucks or Railway of about three meters results in a raw density of 30 kg / m³ and a support area of 50% Compressive stress of only 0.06 kN / m². This is a burden which under that when determining the delivery thickness of the Plate lies. The pressure rises at higher bulk densities tension, but also the compressive strength.

Fig. 1 illustrates an intermediate position in the manufacture of a transport unit 1 , namely mineral wool plates 1 , 2 , 3 and 4 and 5 , 6 and 7 are placed vertically close to each other. The plates extend with the usual width per se perpendicular to the image plane of FIG. 1. The outer plates 2 , 3 , 4 on both sides of the plate stack formed have a greater height than the inner plates 5 , 6 and 7 located between them. The outer and inner plates are offset from one another so that the outer plates form support feet and a cavity 8 is formed below the inner plates. If the plates are set up on a conveyor belt, for example, the cavity 8 can be temporarily filled by a suitable spacer until the plate stack reaches a machine in which the film is wrapped. Instead, the stack of plates in the given formation can first be produced with the plates horizontally supported and then wrapped in foil. Then the plate is then rotated 90 ° so that it represents the intended position of the transport unit. A finished transport unit with a plate stack according to FIG. 1 illustrates FIG. 2, namely the plate stack is firmly and immovably connected on all vertical circumferential sides under tension by a foil wrap 9 . The resistance to kinking is of course dependent on the individual thickness of the individual panels. The resistance to resistance is too low for some panels. Characterized in that the mineral wool plates are provided with a film wrapping under tension, the plates are pressed firmly together so that they cannot move against each other within the transport unit. The foil wrapping has the advantage that the forces are transferred gently to the insulating materials that are sensitive to point loads. A tensile stretch film or a corresponding tensile shrink film is advantageously provided for the film wrapping. This also applies to all of the exemplary embodiments explained below.

The film wrapping can include the entire height of the plate stack, namely the height of the outer plates 2 , 3 , 4th When transporting the transport unit, the forks of the forklift truck can then be pushed through the foils to penetrate into the cavity 8 , which is not a problem.

In order to obtain a further increase in strength, in particular the stability of the transport unit, it is advantageous that the support feet of the outer plates 2 , 3 , 4 are wrapped on the vertical surfaces with an additional film 10 . For the sake of clarity, the film wraps 9 and 10 are only shown in the drawing at the respective edges. However, it is understood that the film wrapping also covers the front and rear vertical surface of the plate stack, which also applies to the feet formed and to the exemplary embodiments described below.

Fig. 3 shows a further embodiment of a transport unit 11 , in which all plates 12 to 17 of the plate stack have the same height. Here, however, a plurality of outer plates 12 , 13 and 14 are offset on both sides to the inner plates 15 , 16 and 17 between them in height so that a cavity 21 for the engagement of the forks one below the inner plates 15 , 16 , 17 Forklift is formed. In this arrangement, 12 , 13 , 14 recesses 22 and 23 are formed above the outer plates. This arrangement has the advantage that the support feet of a stack of plates arranged above can engage in these recesses, thereby ensuring, as it were, firm anchoring between a plurality of transport units stacked one above the other. The plate stack is again provided with a common film wrapping 18 . In addition, both the support feet of the outer plates 12 , 13 , 14 and the upwardly projecting ends of the inner plates 15 , 16 , 17 on the vertical outer surfaces are advantageously equipped with additional film wraps 19 and 20 . The design according to the exemplary embodiment according to FIG. 3 is particularly useful if the strength of the load-bearing surfaces is sufficiently high, for example, to lift a plurality of transport units stacked one above the other from a means of transport in one operation. The available contact surface, namely the common lower surface of the inner plates 15 , 16 , 17 should be fully utilized, for. B. by placing a sheet of appropriate width on the forks of a forklift so that there is no localized deformation of the mineral wool slabs which are easily deformable.

Fig. 4 shows a further embodiment of a trans port unit 24 , in which a plurality of outer plates 25 , 26 and inner plates 28 have the same height. The plates 27 located between them have a lower height and are offset upwards in such a way that cavities 30 , 31 are in turn formed for the engagement of forks of a forklift. A common film wrap 29 is again provided in this plate stack. This embodiment is particularly advantageous when the mineral wool panels are less tightly pressed together within the transport unit 24 . It avoids the risk of slipping of the higher arranged plates.

Fig. 5 illustrates a further embodiment of a transport unit 32 , the structure of which essentially corresponds to the transport unit 1 according to FIG. 1, but here a pressure compensation plate 38 in the form of a chipboard or plywood is arranged below the inner plates 34 , under the two sides of which Edges of strips of insulation 37 are provided, which are stretched by 36 wrap around the support feet of the outer plates 33 a. In this way, in turn, a recess or a cavity 39 is formed for the engagement of forks of a forklift, and any deformations when lifting are avoided. The transport unit is again seen with a common film wrap 35 .

FIGS. 6 and 7 illustrate another execution example of assembling a transport unit. A plurality of individual plate packs 40 , 41 , 42 and 43 are provided with first film wraps 46 and 47 in such a way that the vertical end faces of the plates 44 and 45 are open. The plate packs are arranged closely next to one another and are held together under tension by a second common film wrapping 48 , which covers the outer vertical surfaces including the end faces of the plates 44 and 45 . It has proven to be advantageous to put together four plate packs 40 to 43 to form a transport unit, the two outer plate packs 40 and 43 having a greater height than the two inner plate packs 41 and 42 . They are arranged so that they are offset from one another so that the upper horizontal package surfaces lie in one plane and the cavity for the engagement of a suitable means of transport is located under the inner plate packages 41 and 42 . In order to prevent the inner plate packs from slipping, either double-sided adhesive tapes can advantageously be pushed between the plate packs or the adjacent surfaces can be wetted with a suitable pressure-sensitive adhesive. The adhesive can be applied by spraying the corresponding areas of the film wraps.

FIGS. 8 and 9 show another embodiment of the manner in which a transport unit can be assembled. A plurality, preferably four, individual plate packs 49 , 50 , 51 and 52 are also present here. These plate packs are equipped with a first film winding 55 and 56 in such a way that the top and bottom sides and the vertical end faces of the plates are covered by films. It is then a second common foil wrapping 62 is provided, the parts of the outer large plate surfaces of the outer plate packs 49 , 52 over the top and vertical films 65 and 67 on the undersides of the inner plates packets 50 and 51 is guided. The plates 53 of the outer plate packs again have a greater height than the plates 54 of the inner plate packs. The common film wrap 62 consists of zig-zag shaped film parts 63 , 64 , 65 , 66 , 67 , 68 and 69 , the film parts 63 and 69 can extend over the entire height of the corresponding plate packs, so that the previously open side surfaces 61 can be completely covered. Advantageously, the first Folienum windings 55 and 56 widened edge parts 57 , 58 , 59 and 60 , which abut the edges of the outer large vertical side surfaces of the plate packs 49 , 50 , 51 and 52 . Furthermore, a banderole 70 or a third film winding under tension around the outer large Plattenflä surfaces and the end faces of all plates, so that the plate packs 49 , 50 , 51 and 52 by the action of the second tensioned film wrap 62 and by the action of the banderole 70 or the third film wrap are pressed close together. Only for better illustration, Fig. 9 shows an intermediate position, in which the plate packs are still at a distance from each other before, as I said, firmly pressed together to form a compact transport unit. In this exemplary embodiment, the film parts 65 , 66 and 67 of the second film wrap 62 prevent the inner plate packs 50 , 51 from slipping downward. The large surfaces of the plate packs running perpendicular to the image plane of FIG . B. the surface 61 are open, that is, not covered by the first film wraps in order to achieve high internal friction between the plate packs. This effect is supplemented by the fact that the second film wrap 62 is formed from narrow film strips or from fabrics or ribbons, which are each subjected to tension.

Fig. 10 shows another embodiment of a trans port unit 71 , in which the outer plates 72 of the plate stack have a lower height than the inner plates 73 , the plates being set up such that 72 cavities are formed above the outer plates, in which hollow profiles 75 and 76 , advantageously with reinforcements 77 and 78 are arranged. The plate stack is provided with a tensile film wrap 74 , which surrounds the top and bottom and the outer vertical large side surfaces of the plate stack and the hollow profiles 75 and 76 under tension. The arranged in the outer savings from hollow profiles can, for. B. from corrugated cardboard folded hollow body, which are so resistant that they can withstand both the pressure of the wrapping wrapping the transport unit and the load due to stacked transport units. This embodiment according to FIG. 10 is particularly suitable for transport units which are composed of less resistant, ie comparatively slightly compressible mineral wool plates, so that the transport unit can be moved in a hanging manner by suitable transport means. It is understood that the trans port means engage in the hollow profiles open at the end.

FIGS. 11 and 12, finally, show yet a transport unit 79, which in turn records of a number of mineral wool 80, 81 and 82, is preferably made of rock wool plates, assembled, in which in turn extend the mineral fibers substantially parallel to the large plate surfaces. The plates are in turn arranged close to each other with a vertical position to form a stack of plates. On the bottom and / or top of the plate stack, stiffening elements 83 and 88 are provided, on which support elements 86 and 87 engage for the hanging transport of the transport unit 79 . The plates 80 , 81 , 82 are pressed together at least by a film wrapping 89 which is guided under tension around all outer vertical surfaces of the plate stack. Advantageously, a further film wrap 90 is provided, which covers the bottom and top and the large outer surfaces of the outer plates 80 of the plate stack 79 under tension. The stiffening elements 83 and 88 , which can be provided with incisions 84 and 85 , advantageously consist of strip-shaped, rigid components, such as flat wood or chipboard strips, which run perpendicular to the large vertical plate surfaces and at a distance from the adjacent edges of the plate stack 79 . The support elements 86 and 87 consist of tension-resistant bands which have at least one loop above the plate stack 79 , which are formed by the tension band parts 91 and 92 , the ends of which at a connection point 93 , for. B. are connected to each other by a lock. The vertical parts of the tensile bands acting on the lower stiffening elements 88 can advantageously be embedded between the plates 81 , 82 of the plate stack.

An alternative construction is that a pressure compensation plate is provided on the underside of the plate stack 79 , to which centrally located drawstrings engage, which are embedded with their vertical drawstring parts between the plates of the plate stack and have a loop above half of the plate stack.

The following are general explanations connected.

The presence of recesses or the explained cavities in the transport unit is a prerequisite for one-man transport. The same applies to hanging transport according to FIG. 10 or transport using loops according to FIG. 11.

In the mineral wool panels, according to the invention too Transport units are summarized, it is generally around insulation boards, which are on flat surfaces of Building exterior and interior walls, on flat roofs or on Rafters and greases applied from suitable roofs become. The plates are usually bandaged relocated. The width of the panels can vary from row to row Row can be varied without additional adjustment work attack. When using different widths  Mineral wool panels should, if possible, be a suitable one Ratio of length and width of the panels can be selected.
