Definitions
- the invention relates to a method for producing a packaging and / or Transport unit for plate-shaped insulating materials made of mineral fibers, in particular made of stone and / or glass fibers, in which several insulation boards with their large Surface arranged next to each other and combined into a stack be, the surfaces of the insulation boards in the stack horizontally and / or are aligned vertically and the insulation boards of the stack with one Envelope surrounded and summarized compressed. Furthermore concerns the invention a packaging and / or transport unit for plate-shaped Insulation materials made of mineral fibers, in particular stone and / or glass fibers, which too are combined in a stack and surrounded by an envelope, whereby the large surfaces of the insulation boards in the stack are stacked in vertical and / or horizontal alignment are arranged.
- the subject is the invention an insulation board in the form of a parallelepiped of mineral fibers, in particular of stone and / or glass fibers for use in a packaging and / or transport unit according to one of claims 23 to 37 and / or for use in a method according to any one of claims 1 to 22, the parallelepiped two spaced apart and parallel large surfaces aligned with each other and essentially this has narrow sides extending at right angles.
- Mineral wool insulation consists of glassy solidified mineral fibers with small amounts of a binder, usually a thermosetting
- plastics are connected to one another point by point.
- the mineral fibers are obtained from a melt in a defibration unit is frayed.
- the lower limit of the binder content is given by achieving the strength properties required for use and handling such as compressive and tensile strength.
- impregnants are still used in quantities of approx. 0.1 -approx. 0.4 mass% added.
- Glass wool fibers are made from silicate melts with a relatively high alkali content, optionally also produced boron oxides in such a way that the melt is passed through the fine wall openings of a rotating body. This creates relatively long and smooth mineral fibers with binders and impregnants fall onto an air-permeable conveyor belt.
- the specific The output of such a defibration unit is a few hundred Kilograms of mineral fibers per hour low, so that several aggregates together
- the associated chutes are arranged one behind the other over a production line become.
- the hardening of the structure of the insulation material to be produced fixing binder takes place in a hardening furnace, in which hot air through the fiber web is passed through. Then the cured fiber web trimmed on the side and, for example, split in two in the middle, of which almost lossless insulation boards with a certain length, for example half the line width and any width can.
- insulation felts are manufactured as a further essential form of delivery, which can be rolled up in winding stations. Insulating felts have low bulk densities between approx. 8 to approx. 27 kg / m 3 and possibly low binder proportions.
- the mineral fibers are due to the procedure described above their shape and the applied pick-up technique flat on top of each other the mineral fibers are connected parallel to the large surfaces the mineral fiber web in principle much stronger than at right angles to it. Insulation materials with this structure therefore have a very low transverse tensile strength and can only transmit low shear forces, which for example the rolling up of such insulation felt facilitated. It is also very important that this Insulating felts without permanent damage to the structure with low forces can be compressed very high and naturally only low restoring forces develop.
- Insulating felts made of glass fibers become up to 80% of their size during the winding process Starting material thickness compressed, the restoring forces are so low that for wrapping a wound insulation felt made of glass fiber polyethylene films with a very low material thickness of approx. 100 - 120 ⁇ m, for example can be used. Such films can be used when handling the wrapped Insulating felts withstand dynamic forces.
- the restoring force of the compressed insulation felt is sufficiently large so that the insulation felt even after a few months of storage, its nominal thickness and thus its raw material thickness essentially reached again after removal of the covering.
- the permissible limit deviation of the measured mean value of a sample from the specified nominal thickness is + 15 mm and - 5%, in addition there are also permissible deviations of the measured individual value of the sample from the mean value of ⁇ 10 mm.
- the test specimen is also swaged on the two opposite side surfaces in order to achieve rapid relaxation. Furthermore, the thickness is only measured under a load of 0.05 kN / m 2 . A local falling below the nominal thickness due to the winding technology and within the wound insulation felt due to locally higher compression as well as creep and relaxation behavior that generally occurs during longer storage periods therefore have little technical effect and therefore do not constitute a serious sales obstacle.
- the high compression of the insulation felt represents a very important one Advantage in the storage of the insulation felts in the manufacturing plant, at the trading companies and on the construction site. At the same time, this means significant cost reductions when transporting the light but voluminous in and of itself Insulating felts made from mineral fibers.
- insulation felts are not possible or only to a limited extent.
- manufacturers of insulating materials made from mineral fibers therefore also offer the insulating felts insulating boards, which are characterized by more exact dimensions and which can generally place higher demands on the dimensional stability.
- the permissible tolerances for insulation boards made of mineral fibers of application type W according to DIN 18165-1 "Thermal insulation materials, not pressure-resistant, e.g. for walls, ceilings and roofs" are significantly narrower than for application type WL and are only + 5mm or + 6 for the mean value of the sample % or - 1 mm; plus single value deviations of ⁇ 5mm.
- the load in the thickness measurements is 0.1 kN / m 2 and there is no upsetting of the plate to be tested for relaxation.
- Insulation boards are grouped together in a large number, whereby the stack of insulation boards are provided with a covering and one Packaging and / or transport unit forms.
- the insulation boards in the packaging and / or transport unit are also subject to compression, which is primarily caused by the wrapping.
- the compression of the insulation boards is lower compared to insulation felts and usually reaches one Degree of compression of approx. 20 - 50% of the original material thickness. Insulation boards are made with a slight excess thickness to ensure that the subsequent compression and the storage time creep and relaxation effects to compensate. The degree decreases with increasing bulk density the possible non-destructive compression.
- the insulation materials made from it have the Width of the production line and the height of the fiber web very narrow fluctuations in raw density on.
- the bulk density of insulation felt made of stone fibers can be reduced to approx. 22 - 25 kg / m 3 , whereby it should be noted that the net fiber mass in these insulation materials is only approx. 70%, the remaining shares are the finest unbound non-fibrous components, which do not affect the mechanical properties.
- a material-appropriate elasticization of fiber webs is described in DE 199 04 167 C1.
- a device used for this consists of a Belt system, the repeated increasing compression and controlled decompression the fibrous web or the insulating felt. The insulation felt or Before it is rolled up, the fibrous web becomes even over the entire cross-section elasticized, so that no damage both when rolling up and unrolling occur.
- Insulation boards made of stone fibers come with the usual dimensions of 1 or 1.2 m length x 0.6 or 0.625 m width in thicknesses of approx. 20 - approx. 240 mm. These insulation boards are combined into packaging units, which for handling reasons have a weight of max. 20 kg and at heights from approx. 40 to approx. 60 cm and with their large surfaces contiguous, one in relation to the large surfaces with vertical and / or horizontal orientation Insulation boards are first covered lengthways with a covering, for example in the form of a tensile film made of plastics, paper; composite films made of paper and plastics, metal, paper and / or plastics; Fleece from Natural or synthetic fibers or similar suitable materials encased. Become very common Films made of polyethylene, especially used in the form of shrink films.
- the stack is now compressed so far that, taking into account the expansion or the play of the casing, the packaging unit ultimately has the desired degree of compression in height.
- the deformations of the insulation panels that occur in the process decrease very greatly from the outside inwards.
- the ends of the wrapping are now connected to one another in a force-locking manner, and welded to one another in the case of thermoplastic films.
- the wrapping must now be placed around the compressed stack of insulation boards in a form-fitting manner in order to avoid a strong increase in the pre-compression and thus irreversible damage to the structure of the insulation boards.
- the covering on the end faces must protrude, better still be led around the edges in order to protect the edges of the insulation boards.
- the wrapping can be complete or at a suitable one Zones are shrunk using thermal energy.
- the plates arranged outside in the stack are significantly compressed and deformed. Because the insulation panels arranged in the middle of the stack little or only deformed in the elastic range when compressing the stack under certain circumstances, these insulation boards, especially when a long storage period between the two outside insulation boards yourself and the wrapper. The result is irreversible changes in shape and regularly falling below the nominal thickness for all insulation boards of the stack, but especially the two outer plates. As a remedy can the insulation boards as well as the insulation felts with excessive thicknesses from the start getting produced. However, this reduces the economic efficiency of the manufacturing process without eliminating the disadvantages.
- the object of the invention is to provide a method for producing a packaging and / or transport unit, such a packaging and / or transport unit and an insulation board, in which or in which the above-mentioned disadvantages are avoided and in particular a packaging and / or transport unit which is easy to handle and provided with sufficient stability is formed.
- the solution to this problem provides in a method according to the invention that the individual insulation boards of a stack are compressed before being arranged in the stack and then decompressed in a guided manner, so that the tension built up by the wrapping in the stack is substantially uniform on all the insulation boards arranged and elasticized in the stack is distributed.
- the insulation boards are elasticized by at least one compression acting on their large surfaces, so that a tension built up by the wrapping in the stack on all of the insulation boards arranged and elasticized in the stack acts substantially evenly.
- the parallelepiped particularly in the area of its large area, in particular in the area of its large surface, is compressed and preferably additionally decompressed in such a way that there is an elasticity which, when a plurality of parallelepipeds are arranged, in one surrounded by an envelope Stack enables a uniform stress distribution of the compressive stress in the stack applied to the individual parallelepipeds.
- the method according to the invention allows insulation boards, in particular from Stone fibers, without irreversible deformation in the packaging and / or transport unit compress evenly.
- the insulation boards in their structure is one, but preferably repeated several times, for each further one Step possibly increasing compressions with each subsequently performed Decompression exposed over the entire volume of the insulation board and loosened evenly so that no serious internal breaks or Cracks occur in the insulation board, but essentially those for deformation required forces drop significantly over the height.
- the conveying speed between an upper and a lower band or corresponding Rollers to act on the large surfaces differ his.
- the resulting shift between the top and bottom large surface of an insulation board should be 1 m long Insulation board limited to approx. 5 - 50 mm depending on the thickness of the insulation board become.
- the method according to the invention can be carried out with devices which are equipped with rollers. Due to the possibility of additional height
- the insulation boards can be used with individually adjustable rollers their linear zones of weakness transverse to the roller axes, i.e. mostly in the longitudinal direction of the plate oriented and promoted by the facility at the same time Insulation boards of different material thicknesses and / or raw densities processed different degrees of elasticity are achieved. In this Direction of conveyance, the insulation boards have significantly higher tensile strengths Surface zones and corresponding tensile and bending tensile strengths. On the on the other hand is the resistance to longitudinal compression in this direction of conveyance significantly higher, so that the degree of compression here is narrowly limited or careful must be graded to avoid destruction.

- This device can for example with a frequency up to several Heart operated, so that is particularly suitable in regular Change to produce insulation boards with different degrees of elasticity.
- thermosetting binder acts on the thermosetting binder and thus reduces the rigidity, in particular of the clod-like volume units rich in binder. This results in a more even and faster reaction of the structure to mechanical action.
- Water vapor can, for example, be directly behind a hardening furnace warm insulation boards are pressed or vacuumed. Subsequently these plates are mechanically elasticized.
- Treatment of the insulation boards in an autoclave is much more effective. An approximately fifteen-minute treatment of the insulation boards is sufficient here at 1 bar overpressure, corresponding to 121 ° C, to achieve the intended effect achieve.

- the insulation boards Due to the hydrothermal treatment, the insulation boards are initially damp, However, after a short period of storage they dry themselves or are sucked through with the help Air dried.
- the elasticized insulation boards are stacked on top of each other according to the size of the desired packaging units.
- the forces required for the compression have now been significantly reduced, the insulation materials do not behave like a continuum, ie the compression is different over the thickness of each individual insulation panel and thus to an increased extent over the height of the stack.
- This effect is countered by combining differently elasticized insulation panels in one stack.
- the insulation panels lying inside the stack are more elasticized than the insulation panels arranged further out, in particular than the two insulation panels arranged on the edge in the stack. This initially reduces the deformation forces required when compressing the packaging and / or transport unit and subsequently also the internal stresses in the packaging and / or transport unit. The pressure on the outer insulation boards is reduced and thus the degree of deformation of these insulation boards.
- thermoplastic films are approx. 70 - 120 ⁇ m.
- the wrapping usually takes place around the longitudinal axis of the stack. she should extend well beyond the edges of the stack to allow individual free expansion Avoid area, especially the ends of the insulation boards.
- the Stackability and the visual appearance of the packaging and / or Transport unit are significantly improved if the wrapping around the front Ends of the insulation boards is led around.
- the stack can have one or each one arranged on the outside, in itself stiff top layer made of cardboard or molded plastic parts, for example that lead around the longitudinal edges. These cover layers can be arranged lengthways Corner protection angles can be reduced.
- the corner protection brackets are put on, glued on or put on.
- the stack is now compressed together with the wrapping that is still open. Subsequently the ends of the sheathing are non-positively with each other connected. To compensate for the game of wrapping, the stack can be over the desired size can be compressed.
- the insulation boards only have low restoring forces due to their elasticization can develop the ends of shrink film sheets together be welded.
- the casing can then be replaced by a thermal treatment are shrunk, in particular the in In the longitudinal direction of the stack protruding ends of the wrapper treated become.
- Thermoplastic films expand over time under tension.
- the wrappings of the better recycling because of wrapping, shrink wrapping or more resistant tapes glued or covered with tear-resistant adhesive tapes.
- the packaging and / or Transport units placed upright, if possible, for additional Loads e.g. to avoid in large containers. Since the sides of the Insulation panels are not elasticized, this results in a stable position individual packaging and / or transport unit.
- the insulation panels or of the stack at least one tear-resistant broad band shrunk onto the wrapping or glued on.
- Adhesive tapes are also suitable for this. With help this is arranged, for example, in the region of the partially open end faces The packaging and / or transport unit can hold belts in the area of the end faces be gripped without the risk of damaging the wrapping in this area exists.
- the handles or carrying aids prevent the packaging and / or Transport unit, especially ground on construction sites are damaged, causing damage to the high-tension envelopes and in the event of external damage, e.g. even when touched of scaffolding parts and the stack falls apart. remedy creates the attachment of the carrying aids to the by the compression in favorably reduced narrow sides of the packaging and / or transport unit.
- the carrying aids can be on both ends of the packaging and / or Transport units are attached.
- An insulation board 1 shown in Figure 1 is designed as a parallelepiped and has two aligned and spaced apart large surfaces 2 that are perpendicular to the large surfaces 2 arranged long sides 3 and at right angles to the large surfaces 2 and to the long sides 3 arranged narrow sides 4 connected to each other are.

Description
Insbesondere bei gering verdichteten Dämmstoffen zeichnen sich die Grenzflächen der ursprünglichen Lagen des Primärvlieses auf den beiden großen Oberflächen durch quer zur Produktionsrichtung verlaufende Furchen, Verfärbungen, Anreicherungen bindemittelfreier Mineralfasern usw. ab. Bei Belastungen der beiden großen Oberflächen durch lokalen Druck oder beim Biegen hieraus hergestellter Dämmstoffplatten reißen diese bevorzugt entlang der Grenzflächen zwischen den Primärvlieslagen auf. Die Zug- und Biegezugfestigkeit dieser Steinwolle-Dämmstoffplatten ist deshalb in Produktionsrichtung deutlich geringer als im rechten Winkel dazu.
Bei einem Aufrollen eines Dämmfilzes aus Steinfasem reißt der Dämmfilz auf oder ganz durch. Ähnliche Effekte treten insbesondere bei Dämmstoffplatten mit großer Materialstärke und/oder Rohdichte auf, wenn dort einzelne Oberflächenbereiche gestaucht werden.
Eine weitere deutliche, aber eigentlich nicht werkstoffgerechte und auch nur schwer steuerbare Elastifizierung erfolgt durch das komprimierende Aufrollen der Dämmfilze. Allerdings läuft der Vorgang wegen der Form der sich bildenden Rolle nicht gleichmäßig ab, so dass die inneren Lagen der Rolle wesentlich stärker deformiert werden als die äußeren. Die dabei ausgelösten Beschädigungen der Dämmfilze führen zu Mängeln bei der Verarbeitung.
Um den Einsatz von Verpackungsmaterialien zu minimieren, werden erst jetzt die Enden der Umhüllung kraftschlüssig miteinander verbunden, bei thermoplastischen Folien miteinander verschweißt. Die Umhüllung muß nun möglichst formschlüssig um den gestauchten Stapel Dämmstoffplatten gelegt werden, um eine starke Überhöhung der Vorstauchung und damit eine irreversible Schädigung der Struktur Dämmstoffplatten zu vermeiden. Gleichzeitig muß die Umhüllung an den Stirnseiten überstehen, besser noch um die Kanten herumgeführt werden, um die Kanten der Dämmstoffplatten zu schützen.
Vor allem bei Dämmstoffplatten mit mittlerer bis höherer Rohdichte hat sich daher eine ergänzende hydrothermische Vorbehandlung als vorteilhaft erwiesen. Hierbei wirkt prinzipiell erwärmtes Wasser, insbesondere in Form von Wasserdampf auf das duroplastische Bindemittel ein und reduziert damit die Steifigkeit insbesondere der bindemittelreicheren schollenartigen Volumeneinheiten. Dadurch wird eine gleichmäßigere und schnellere Reaktion der Struktur auf eine mechanische Einwirkung erreicht.
Praktischerweise werden die in dem Stapel innen liegenden Dämmstoffplatten stärker elastifiziert als die weiter außen angeordneten Dämmstoffplatten, insbesondere als die beiden im Stapel randseitig angeordneten Dämmstoffplatten. Damit verringern sich zunächst die bei der Komprimierung der Verpackungsund/oder Transporteinheit erforderlichen Verformungskräfte und in der Folge auch die inneren Spannungen in der Verpackungs- und/oder Transporteinheit. Der Druck auf die äußeren Dämmstoffplatten wird geringer und damit auch der Verformungsgrad dieser Dämmstoffplatten.
Jede Lasche kann durch lose eingelegte, aber auch voll- oder teilflächig auf oder eingeklebte Pappstreifen oder dickere Folien vorzugsweise im Bereich des mittleren Eingriffloches oder Schlitzes verstärkt werden. Gleichermaßen können eine oder beide Decklagen um eine der beiden Seitenflächen herum bis in diese Laschen verlängert werden.
