The sleeve (16) consists of a material porous to water vapor and is in the form of a film, a fleece and/or a membrane.

Description

The invention relates to a storage and transport unit consisting of at least one stack of plate-shaped insulating material elements made of mineral fibers, in particular rock wool and / or glass fibers, and a covering, which at least on the surface and the side surfaces of the Stack and preferably also on the underside of the stack.

The effect of thermal insulation materials is based on a high internal Porosity, consequently on a large number of fine and very fine pores in the insulation material. There are insulation materials known by nature are hydrophilic and therefore through their open or continuous pores Take up water capillary or through internal condensation of water vapor and mostly evenly inside the insulation material to distribute. The absorption of water in the insulation material can, however Adversely affect the insulating ability of the insulating material.

In the case of insulating materials made from rigid plastic foams, for example from expanded ones The capillary absorbency is very low in polystyrene. The recording Most of the water in these insulation materials is used via the vapor phase with subsequent condensation of the water in the cavities. The absorption of water vapor is relatively slow. On the other hand, such water-contaminated ones dry out Insulation materials under construction conditions are also very slow.

Insulating materials made from cellulose fibers absorb moisture both in the fiber structure as well as adhesion to the fibers or capillary between tightly packed fibers. The capillary suction is parallel to that Fibers significantly higher than perpendicular to the longitudinal fibers.

The well-known insulation materials, namely mineral wool insulation materials consist of glass and / or rock wool fibers, the Glass fibers with average diameters of approx. 2 to 5 µm with phenol-formaldehyde-urea resins are bound at certain points. The amounts of binder amount used for the thermal insulation of buildings Insulation materials approx. 2 to 8% by mass. A hydrophobicity of the fibers is caused by oil additives in the range between 0.2 and 0.4 mass% achieved so that these mineral wool insulation materials with even binder distribution made of fine glass fibers only in the direction of the individual fibers have low capillary water absorption. But it is almost impossible that the binder distribution in the entire insulation material done evenly. Furthermore, the impregnation with the oil additives not evenly formed over the entire volume. As a result water can be taken up capillary at the points of the insulation material water vapor will precipitate, on which the fibers agglomerate, i.e. in areas where the fibers are not oiled or otherwise Fabrics are impregnated. With known mineral wool insulation materials Made of glass fibers, for example in composite thermal insulation systems or used in flat roof constructions can be a relative Air humidity in the pores of the insulation> 80% can be reached, whereby the glass fibers are attacked by water vapor and condensation. Long-term exposure to moisture leads to these insulation materials weakening of the binder. The reasons for this lie in the relatively low chemical stability of the glasses used. Such Glasses are described for example in DE-A 196 14 572.

Fibers with a higher bio-solubility are for example from EP-A-0 711 258 known. These glass fibers are made from molten glass, that work well with conventional shredding machines to let. Sufficient moisture resistance is achieved which is determined in a standard procedure. With this procedure Glass semolina with a diameter of approx. 360 to 400 µm five hours in water cooked and then the dissolved substance determined.

In addition to glass fibers are also used for the production of insulation materials Rock wool fibers used. The bio-solubility of the well-known rock wool fibers is at a pH of 7.5 with a solution rate of approx. 2 nm / day. If the pH falls to 4.5, the solution rate is 3 nm / day. Rock wool fiber compositions are also known in which the above values are 2 to 5 times in basic Range and increase 10 to 20 times in the acidic range. As The half-life of fine fibers after intratracheal is the measure of bio-resistance Instillation in the respiratory tract of rats. In the case of glass fibers the half-lives have been reduced from> 200 days to <40 days been. With the so-called bio-soluble rock wool fibers the half-lives were reduced from about 270 days to <60, especially < Depressed for 40 days. If only the half-lives of the individual fibers no direct measure of the usability of the mineral wool insulation materials are, it can be assumed as very likely be that the sensitivity of the glass fibers to chemical Corrosion has increased 4 to 6 times.

The mixtures of phenolic resins and used in fiber insulation Urea-formaldehyde resins are primarily from a cost perspective and because of the favorable fire behavior of the nitrogen-containing ones Connections selected. But it is known that in particular Urea-formaldehyde resins tend to hydrolise.

Based on the above, it can be seen that the reduced Resistance to the manufacture of mineral wool insulation materials used glasses and the relatively unstable binders cause that the fiber insulation materials are damaged under hydromechanical loads can be. Of course, these are compositions fiber insulation materials not only with regard to the attack of water, but also only to a limited extent with regard to other chemical attacks tough.

In addition, fiber insulation materials are exposed to mechanical loads are. These stresses also occur in the form of internal ones, for example Tensions caused by the partially high compression and extreme Deformation of the fiber masses are induced. A long time and high hydrothermal loads can become more or less pronounced Relaxation processes lead to significant loss of strength are measurable. Mechanically loaded, high-density mineral wool insulation materials are therefore only storable for a short time, so that they are so fast as possible to be used for their intended use in order to the strength values achieved during manufacture are also maintained during take advantage of the installation phase, which often involves the greatest stress to be able to.

In addition to the mechanical loads described above occur hydromechanical loads even during the use phase of the insulation materials. The simultaneous appearance of both the mechanical as well as the hydromechanical loads is of particular importance negative meaning. In common use is with a hydromechanical Insulation materials exposed to water vapor or below Under certain circumstances, condensation in the surface areas of the insulation material count. With only low hydromechanical loads occur in the Usually no damage. It should be noted that hydrothermal Stresses on a thermally insulated component, for example of a house already different during a day or during the year are. The different loads on the fiber insulation materials with moisture also has an alternating mechanical load on it Fiber insulation materials result. For example, it is known that partially damp and thus weakened resin films in the dry state can regenerate, but not the original strength values more can be achieved. A constant change of the hydromechanical Strain on the fiber insulation materials thus leads to a continuous Loss of strength in the course of an aging process.

Experience has shown that the mechanical load on roof insulation panels is in the installation phase and / or during a longer storage phase on strongest. The same applies to insulation boards in thermal insulation composite systems be claimed on own load and on wind load. But there are other loads that weaken the mechanical properties, known for example in the manufacture of fiber insulation materials. So in the manufacture of sandwich elements from wood wool lightweight building boards these wood wool lightweight panels in a formwork underneath Pressure stored in an extremely humid environment until a Portland cement has achieved sufficient strength and a sandwich element can be demolded. Such sandwich elements are, for example Mounted under floor ceilings. The fiber element must do this Bear your own weight and the weight of an applied layer of plaster.

As stated above, the mineral fiber insulation materials are stored for a longer period of time to loss of strength. This is especially true if highly compressed mineral fiber insulation materials over a longer period of time with increased relative humidity and stored in vapor-tight packaging become. Such storage times occur, for example, at the manufacturers of mineral fiber insulation materials when seasonal Production fluctuations were not balanced become. As a result, longer storage times, for example in the Winter or spring occur since these seasons are lower There is demand for mineral wool insulation materials. A constant Utilization of the production facilities therefore leads to a longer storage time as a result of periodic construction activity, with the mineral fiber insulation materials must be stored outdoors for months. To storage volume to save will be mass-intensive, high-density and due to stacking the transport units on top of each other Insulation materials included in this storage phase. Similar relationships occur not only with the manufacturers in the course of the periodic Construction activity, but also on construction sites, with dealers or at long Ship transports on. To protect the mineral fiber insulation materials provide them with complete packaging, in particular a To provide protection against the weather. Such packaging consist of envelopes, mostly of polyolefin, in particular Polyethylene films are made. Polyethylene films with thicknesses d ≥ 0.1 mm according to DIN V 4108-4 have a water vapor diffusion resistance number µ from 100,000. This results in a diffusion equivalent Air layer thickness as a product of the material thickness with the Water vapor diffusion resistance number of approximately 100 m. The used Films are therefore clearly water vapor retardant. As a result they can also be used as steam brakes in construction. There such packaging films usually in thicknesses of about 60 to 100 µm are used and the above also with smaller film thicknesses to set the water vapor diffusion resistance factor µ the packaging films reach blocking values of 6 to 100 m. Since the thin films for strength reasons in larger packaging units or stacking in several layers must be increased the water vapor impermeability continues. A complete wrap a stack of mineral fiber insulation boards leads to temperature increases, for example, in the case of intense heating due to solar radiation in the existing between the film and the insulation Room for a temperature rise to relatively high values. On resulting temperature difference between the outside temperature and the interior of the packaging leads to one Water vapor partial pressure drop inside the stack of mineral fiber insulation boards. At the same time, a water vapor partial pressure drop occurs compared to the environment of the insulation stack, which water vapor partial pressure drop represents a driving force so that water vapor due to unavoidable leaks or through open areas the packaging (contact surfaces on pallets) in the areas with the diffused at the highest saturation pressures. When the outside temperature weakens condensation quickly forms on the inside the packaging film. Repeating the heating will As a rule, defrost water does not evaporate, but remains in liquid Form in the packaging. This leads to an increased failure of condensation, so that with regular repetition of the warming literally water through the daily cycle of the insulation stack pumps. Because the condensation in the insulation package even when reversed of the water vapor partial pressure gradient do not diffuse outwards can, the air in diffusion-open insulation materials has a relative humidity from> 80%. On the surfaces of the mineral fiber insulation boards there is condensation from the mineral fiber insulation boards is at least partially absorbed. Under unfavorable circumstances the mineral fiber insulation boards completely take away the defrost water on.

The storage and transport units in question can be used in the same way due to damage to the packaging film rainwater take up. Rainwater has due to the pollution of the Air may have pH values between 1 and 5, so that the surfaces of mineral fiber insulation boards, which are made in very acidic medium sensitive mineral fibers exist through the absorption of rainwater can be significantly weakened. The Haftverbund with the usual in the processing of mineral fiber insulation boards This can reduce glue or plastering.

On the basis of the prior art described above, the object of the invention is to further develop a storage and transport unit in such a way that hydromechanical loads on the insulation elements, in particular insulation panels, are substantially avoided, or at least reduced.

The solution to this problem provides that the covering consists of a water vapor-permeable material in the form of a film, a fleece and / or a membrane.

With such a storage and transport unit, care is taken that the condensation water that collects when heated within the storage and Transport unit is removed. For this purpose is a wrapper provided, on the one hand, a diffusion of the defrost water from the inside the storage and transport unit into the environment and on the other hand penetration of, for example, rainwater into the bearing and Transport unit prevented. The covering is thus semi-permeable trained and prevents the disadvantages described above known envelopes, so that in the storage and transport unit arranged insulation elements against hydromechanical loads and damage are protected.

It has proven to be advantageous to form the covering from a nonwoven composite. For example, materials are used for the covering which have diffusion-equivalent air layer thicknesses s _D <0.01 to approximately 8 m, preferably <4 m.

For the production of weatherproof and extremely water vapor permeable, but against rain, against weather influences resistant and mechanically resilient nonwovens are in particular Fibers made of polyester, polyolefins, polyamide alone or in combination suitable with each other. Suitable fibers take over the connection of the fibers mainly forming the fleece. Suitable nonwovens are mostly with binders such as polyacylates, styrene polymers, PVAC-PVC, Polynitrile butadiene and / or polyurethane bound.

To create wrappings that depend on the size of the warehouse and Transport unit are designed, it is proposed that the envelope is formed in several parts, the individual parts of the casing are glued, welded and / or sewn together. At a such a configuration can be kept in stock for the casing a few standard dimensions may be limited without this being a limitation the maximum size of the storage and transport unit goes hand in hand, since the individual parts of the wrapping correspond to the size the storage and transport unit can be assembled.

The nonwovens forming the covering are preferably metallized or trained with liquid barriers so that ingress of rainwater can be effectively prevented.

As an alternative to the use of nonwoven fabrics according to the invention, it is also possible to use foils, for example made of polyamide (μ 50,000), polypropylene (μ 1,000), polyvinyl chloride (μ 20,000 to 50,000) and / or polyester. Depending on the amide concentration and the relative humidity of the ambient air, for example, polyamide films have high water vapor permeability. A polyamide film with a material thickness of 50 µm can have a diffusion-equivalent air layer thickness s _D <0.3 m at 80% relative humidity and is more permeable to water vapor than with dry ambient air.

In order to increase the water vapor permeability of the films, they can slotted or perforated with needles. Thanks to such techniques relatively thick foils are used. In an advantageous embodiment are the slits or perforations in at least one side surface and / or the contact surface of the storage and transport unit, so that rainwater can enter through these slots and Perforation is prevented. Of course there is the possibility of Arrangement of slits and perforations even with wrappers Fleeces.

For better utilization of the water vapor permeability of thinner foils are they glued to the whole or part of the supporting fabric, welded on or applied, for example, by sewing on, for example connected to the supporting fabric in a different way. The supporting fabric can be in the form of straps, which itself again are connected to one another by seams, adhesive bonds or the like. These straps are arranged essentially at right angles to each other, with part of the straps on the surface of the top plate-shaped Insulating element is arranged running in the longitudinal direction. The belts arranged at right angles therefore run transversely to the Longitudinal extension of the plate-shaped insulation elements, the Belts over the side walls of the storage and transport unit and if necessary also extend over the contact surface of the like. The supporting fabric, in particular the straps, can be between the Insulation elements and the film or the fleece arranged or on be applied to the outside of the film or fleece.

The wrapping of the storage and transport unit according to the invention is for any size stack of plate-shaped insulation elements suitable. Here it has proven to be advantageous to use the packaging as reusable packaging train, because in this way packaging costs on the part of Manufacturer can be saved. Another advantage of this design is that due to existing packaging take-back regulations returning packaging can be reused and do not incur any recycling or landfill costs. Preferably is the wrapping in the form of a hood, a cape or completely closed packaging. To make things easier packing the insulation elements or removing the Wrapping at the processing location is provided that the wrapping is formed in several parts and the individual parts in particular in the form of a web are formed, which tracks releasably connectable to each other are. Zippers, push buttons, Buttons and buttonholes, hooks and eyes, Velcro fastenings and / or Lacing provided. To the connections between the railways It is planned to protect against the ingress of rainwater that the connections between the webs have covers.

According to a further feature of the invention it is provided that the casing Outside tabs for attachment to scaffolding structures have with which the storage and transport unit either on funding or can be attached to work scaffolding.

According to a further feature of the invention, it is provided that the bearing and transport unit has straps on which, for example, soft rubber, air-filled pillows, hard foam, woods and the like in the form of Stripes or studs can be applied. The strips and studs serve as a support body between stacked transport units or space for insertion e.g. the fork of a forklift create. The support bodies have heights of 2 to 15, for example cm, preferably 4 to 8 cm.

The belts are preferably placed around the stack of insulation and serve at the same time, the fixed constriction of the plate-shaped insulation elements. But there is also the option of retrofitting the belts to place the storage and transport unit, i.e. that the straps then lie on the wrapping. Finally, there is also the option of Support body partially or completely with the covering by gluing or by mechanical fasteners, for example To connect push buttons, hook fabric or the like.

Finally, it has proven to be advantageous to design the casing from a water vapor-permeable material with a weight per unit area of between 5 and 75 g / m ² . With these basis weights, in particular non-woven fabrics with very low water vapor diffusion resistance numbers are formed. Since the tensile strength of the nonwoven also depends on the weight per unit area, this can be changed with regard to the expected stress. If only weather protection is required, the weight per unit area can be kept significantly lower, while heavy, more resistant nonwovens are necessary for the transport of the insulation elements on open motor vehicles. Such non-woven fabrics can be produced on site and immediately applied to the stack of insulation elements. This results in a significant cost saving compared to pre-assembled nonwovens.

Figure 2

a side view of Figure 1 but with two belts and

Figure 3

a side view of Figure 1, but with a different configuration of the support body and a different configuration of a casing.

In Figure 1 is a storage and transport unit consisting of a stack 1 plate-shaped insulation elements 2 made of mineral fibers. The plate-shaped insulation elements 2 are horizontally one above the other piled up. On the underside of the stack 1 there are two support bodies 4 and 5 provided, made of a material that can be used for insulation purposes consist. The support body 4, 5 have a rectangular cross section and the height 8 of the support body advantageously corresponds approximately the thickness of an insulation board 2, 3 of the stack 1 lying thereon.

The stack 1, together with the support bodies 4, 5, is wrapped 16 surrounded by a water vapor permeable material in Form of a film. The envelope 16 lies both on the side surfaces the insulation boards 2, 3, as well as on the surface of the insulation board 2 and the contact surfaces of the support body 4, 5. As a foil a film made of polyamide is used for the covering 16. Alternatively films made of polypropylene, polyvinyl chloride and / or polyester can be provided his.

In the area of the side surfaces of the insulation panels 2, 3, the covering has 16 slots 17 through which condensation from inside the Storage and transport unit can escape to the outside. The slots 17 are by cover elements, not shown, in the form of film strips or fleece strips covered.

Figure 2 shows, compared to Figure 1, an envelope 16, the hood is trained. In addition, the embodiment differs 2 of the embodiment of Figure 1 in that each support body 4, 5 by a belt 6 and 7 with the stack 1 is connected, so that both the stack and the support body are each wrapped by a common belt 6, 7. More appropriate As shown, the two support bodies 4, 5 are transverse to Longitudinal extension of the stack 1, i.e. perpendicular to the image plane of the figures 1 and 2, and spaced apart from each other at the bottom of the stack a certain height 8 arranged so that the support body over extend the entire width of the stack. For an even distribution the weight of the stack 1 to the two support bodies 4, 5 reach, is the distance between the inner edges of the support body 4, 5 from each other chosen about twice as large as the distance between the outer edges the support body 4, 5 from the adjacent edges of the stack 1.

In the exemplary embodiment according to FIG. 1 or FIG. 2, the insulation boards are 2, 3 stacked horizontally one above the other. But there is also the possibility of the insulation panels 2, 3 vertically next to each other, that is to be arranged parallel to the image plane of FIG. 2. Preferably both exist the stacked insulation boards 2, 3 as well as the support body 4, 5 made of mineral wool, preferably rock wool.

The straps 6, 7 can consist of a film or a non-woven fabric, as far as the straps 6, 7 have sufficient tensile strength, the one Allow connection of the insulation panels 2, 3 and the support body 4, 5. The use of a film has the advantage that the film when wrapping the stack and the support body 4, 5 tightly and that, for example, a shrinking process due to heat treatment superfluous. Usable films with a proportionate can be used here small thickness of usually less than 20 µm. Greater stability of the Straps 6, 7 can be achieved, for example, in that the films in Multiple layers 11, 12 (Figure 3) can be arranged. The multiple layers are formed by wrapping the stack 1 several times. To this For greater strength and transport security is achieved for the In the event that minor damage occurs during transport of the transport unit, how small tears appear in the outer film layer. Basically can be said, however, that the foils u.a. the essential Bring advantage in arranging the storage and transport unit allow a sufficiently large strength of the like, essential areas of the insulation panels 2, 3 not of the film material the straps 6, 7 are covered, so that in these areas Insulation panels 2, 3 can emit moisture, which then through the Envelope 16 diffuses into the environment.

The envelope 16 shown in Figure 2 is the contact surface of the Stack 1 open, so that water vapor from this open side the storage and transport unit can escape.

In contrast to FIG. 2, FIG. 3 shows a storage and transport unit, in which the envelope 16 in turn on all side surfaces, the surface and the contact surfaces of the stack 1. Further differentiate the support body 4, 5 according to the embodiment Figure 2 in that the support body from a number close together arranged single body with a square cross-section are. These single bodies are longitudinal and diagonal cut into triangular bodies 13, 14. The perpendicular to the image plane extending cutting surface is provided with the reference number 15. The Invention is not limited to the illustrated embodiments. Rather, various changes are possible without the protection area to leave the invention. For example, the support body 4, 5 made of soft rubber, air-filled pillows, hard foam, wood or the like consist. They can be designed in the form of strips or tunnels. On Non-woven fabrics, in particular non-woven fabrics, can also be used instead of the films mentioned with fibers made of polyester, polyolefins, polyamide and / or mixtures thereof be used. These fibers of the nonwovens are made with binders, such as polyacrylate, styrene polymers, polynitrile butadiene, polyurethane or the like. The envelope 16 can be made in several parts be, the individual parts of the envelope 16 with each other are connectable, in particular glued, welded and / or sewn are. But it is also conceivable that the parts of the sheath 16 are detachable are interconnected.
