Definitions

  • Insulation board for the insulation of external walls made of profiled sheets
  • the invention relates to an insulation board made of mineral fibers, in particular stone wool, for insulating outer walls made of profile sheets with a U-shaped cross section, in particular designed as a cassette profile, at least one leg of the profile sheet being bent at its free end, preferably at right angles to a leg, and thus runs essentially parallel to a web connecting the legs of the profiled sheet, consisting of a parallelepiped having two large surfaces running parallel and at a distance from one another, which are connected to one another via side surfaces arranged at right angles to one another and to the large surfaces, at least one of them in at least one side surface Incision is arranged, which serves to receive the part of this leg running parallel to the web.
  • the outer walls of industrial or other halls are clad, for example, with profiled sheets, which in turn are attached to lightweight metal constructions using bracket technology using blind rivets or self-drilling screws.
  • the linear holding structures can be arranged vertically or horizontally on the supporting wall shell made of, for example, concrete, masonry or a further sheet metal shell or its supporting structure.
  • Vertical support structures are usually only connected to the load-bearing wall shell or substructure at a few points.
  • the horizontal brackets are often made of Z-shaped sheets. Adhesions of this type are also arranged on flat roofs or parapets to fasten metallic roof seals.
  • the best-known profile shapes are trapezoidal or wave-shaped, further examples can be found in DIN 18807 or in the catalogs of the relevant manufacturers.
  • the known profile designs also include the standing seam profile and the cassette profile with belt beads.
  • the sheets can be made of sheet steel or aluminum, for example. Claddings made of wood, wood-based materials or GRP are also used.
  • So-called wall cassettes form a frequently encountered form, for example according to EP 0 849 420 A1.
  • these cassettes consist of sheets which are folded in a U shape and provided with reinforcing beads.
  • the legs of the cassettes themselves are bent in the same direction again at right angles.
  • the cassettes are attached one above the other - so on the supporting wall - that the legs meet once and their bent ends overlap.
  • the overlapping legs form webs to which clothing panels or sheets can be attached.
  • Both the actual legs of the cassettes and the webs can have stiffening profiles (beads). With some cassettes, the ends of the webs are also bent inwards again or run into a corrugation in the same direction.
  • the voids between the inner wall shell and the outer cladding are completely or partially filled with insulation.
  • the distances between the console-like holding structures and the heights of the cassettes vary between approx. 450 - 1000 mm.
  • the numerous metallic connections between the outer cladding and the inner wall shell create a large number of massive thermal bridges, which significantly reduce the insulation effect and thus lead to high transmission heat losses from the walls and, of course, the corresponding roof structures. Additional heat losses also occur if the insulation materials are not pressed into the cassettes so that the outside air flows against the inner wall shell.
  • these constructions have further disadvantages.
  • the thermal bridges regularly cause condensation to form in the wall structures, which in turn impair the insulation effect and can cause corrosion damage. In the event of a fire, the thermal bridges promote energy transmission through to fire propagation.
  • the soundproofing of such constructions is low despite the cavity damping due to the mineral wool insulation materials mostly used and the inherently low stiffness, in particular the light bracket constructions.
  • the mineral wool insulation board has the outer height of the wall cassette. There is an incision on the upper side surface of the insulation board, into which the downwardly angled, web-shaped legs of two wall cassettes engage from above. The incision is made so that the insulation layer slides over the outer web of the stacked wall cassettes and thereby covers them.
  • the insulation board used has low bulk densities so that the board can essentially adapt to the contours of the wall cassette. In order to be able to transfer significant forces from the cladding to the substructure, the insulation board has a higher here strength, which is achieved by a higher bulk density.
  • spacer elements made of a low thermal conductivity material are inserted into the horizontal joints between the insulation boards. These profile-like spacer elements are supported on the cassette webs, but are not firmly connected to them.
  • WO 00/77318 describes a similar insulation board and its use.
  • the angled webs of the two cassettes arranged one above the other engage from above in an incision made on one side surface of a mineral wool insulation board.
  • the bulk density of the mineral wool insulation layer should gradually increase slightly from the inside to the outside from a low value of around 35 kg / m to a high value of around 65 kg / m.
  • the fibers of the insulation board can also be arranged perpendicular to the large surfaces, which corresponds to a so-called lamella board. Sub-areas of the outer, more highly compressed plate zones therefore lie on the ridges mentioned here.
  • the outer linings are attached point by point, for example by screws.
  • the He indation is based on the task to improve insulation boards of the type mentioned in such a way that deformation of the boards, which affect the dimensional stability and thus the insulation effect of the boards after they are fastened to the substructure, during the manufacture of the insulation boards in can be avoided in a particularly simple and appropriate manner.
  • the invention has the advantage that the incision on the insulation board can be formed in a simple manner as a slot-shaped recess during its manufacture. It is possible in a simple manner to give the recess such a sufficient width that the angled webs of the wall cassette can engage in the recess without deforming the insulation board. This considerably simplifies the installation of the insulation panels on the wall construction. This is because the insulation panels can be pushed very easily and without any force using the slot-shaped recess from below over the two angled webs of stacked cassettes arranged one above the other.
  • the insulation panels do not undergo any deformation, which on the one hand benefits the dimensional accuracy of the fastening to the wall construction, but on the other hand, damage to the insulation panels, which can otherwise occur due to being pushed onto the angled webs of the abutting wall cassettes by force, can also be avoided in a particularly simple manner ,
  • inadmissible deformations of the insulation panels can be avoided in a particularly expedient manner by mounting them in that the width of the slot-shaped recess is at least equal to the thickness of the angled web.
  • the slot-shaped recess preferably has a width between approximately 2 mm and approximately 10 mm.
  • a width of more than 10 mm can also be provided, provided that care is taken to ensure that the remaining web of the insulation board is of sufficient thickness to prevent the web from breaking off.
  • the material thickness or thickness of the angled web, including any beads or bends, is to be designed in such a way that a positive or frictional connection can be established between the insulation board and the profiled sheet.
  • the mineral wool insulation boards designed according to the invention preferably have slot-shaped recesses only in one of the two long side surfaces.
  • the slots can have straight or curved flanks. Thanks to these recesses, the insulation boards can be pushed smoothly, ie without deformation and quickly from the open end faces over the sharp-edged web plates that have beads or end in chamfers. This This is particularly advantageous for stone wool insulation boards with a steep storage of the individual fibers due to a pronounced longitudinal-height compression of the fiber mass or a structure that is strongly intermingled.
  • Suitable mineral wool insulation boards have bulk densities of approx. 20 - 120 kg / m 3 .
  • stone wool insulation boards come into consideration that have a higher density outer zone or a glued top layer. This zone is about 10 to about 70 mm thick. The bulk density of this zone or top layer is approx. 60 - 200 kg / m 3 .
  • the insulation boards only have strip-shaped layers of specially prepared mineral wool fibers with bulk densities of approx. 300-1000 kg / m 3 in the particularly highly stressed areas above the webs. This means that the densification of the zone near the surface can be significantly reduced or completely eliminated.
  • These plates can be covered with glass fleece, glass silk fabric or similar non-combustible cover layers with low diffusion resistances.
  • the outer sheet metal shells can now be fastened with the usual fastening screws, these, e.g. with the help of torque wrenches, against the resistance of the then compressed insulating materials, are screwed into the web plates.
  • screws with a double thread and different shaft diameters represent an essential addition to the insulation boards according to the invention.
  • screws of this type eg Fischer RW 209 Duo fastener
  • the shaft diameter above the first thread used to screw the screw into the web plates is widened conically.
  • the screw is thereby bolt-like anchored in the two sheets standing one behind the other in such a way that they can also absorb shear forces from their own loads.
  • the shear forces are generally reduced by the frictional forces exerted when compressing the insulation.
  • insulation materials with relatively high compressive strengths of> approx. 200 kPa at 10% deformation are used.
  • the profiled sheets are pressed firmly onto the stiff cover layers of the insulation material and now cause significantly higher frictional forces.
  • the cover layer prevents the insulation layer and the profiled cladding sheets from bulging out, particularly at right angles to the profiling direction.
  • Insulation materials with a pronounced fiber structure are installed in such a way that the very strictly oriented interstructure ⁇ F ⁇ s ⁇ OrieT ⁇ tieTi ngeh are subjected to pressure.
  • the higher-density outer zone extends into a region of a boundary layer which is arranged between the recess and the adjacent large surface.
  • the higher density outer zone and / or the top layer is arranged exclusively in the area of the recess.
  • the higher-density outer zone or the top layer is located in the area of the above-described web made of mineral fibers, so that this web is reinforced and has a higher bending strength which prevents it from breaking off.
  • Fig. 1 shows a perspective view of an insulation board with a slot-shaped recess on a side surface of the insulation board and
  • FIG. 2 shows a perspective partial illustration of an embodiment of such an insulation board modified in comparison to this.
  • the insulation plate 1 shown in FIG. 1 consists of a preferably cuboid insulation body 2 with "a strong " longitudinal-height compression with a higher compression zone 3.
  • 1 and 2 consist of rock wool and are intended for insulation of external walls made of profiled sheets with a cassette profile made of U-shaped sheets, in which at least one leg is bent again in the same direction parallel to the cassette floor , wherein two angled webs of cassettes arranged one above the other engage from above in the slot-shaped recesses 5 arranged on the side surfaces 4 of adjacent insulation panels 1.
  • Each slot-shaped recess 5 is formed with a width such that the angled webs of the cassette profiles engage in the recess 5 without deformation of the insulation board 1.
  • the width of the slot-shaped recess 5 is at least equal to the thickness of the angled web.
  • the recess 5 can have straight or curved flanks.
  • the bulk density of the insulation board 1 can be approximately 20-120 kg / m 3 , whereby it can have the higher density outer zone 3 and / or also a glued top layer 6.
  • the bulk density of the higher density outer zone 3 or the top layer 6 is approximately 60-200 kg / m 3 .
  • the higher density outer zone 3 is about 10 to 70 mm thick.
  • the insulation board 1 can also have a strip-like insulation layer 8 made of mineral wool fibers with a bulk density of about 300-1000 kg / m 3 only in highly stressed areas 7 above the recess 5.
  • the insulation layer can be covered with glass fleece, glass silk fabric or a similar non-combustible cover layer 9 with a low vapor diffusion resistance.
  • the higher-density outer zone 3 extends over an entire large surface 10 of the insulation board 1.
  • the thickness of the higher-density outer zone 3 corresponds to the right-angled distance between the large surface 10 and the recess 5, so that a between the more highly compressed outer zone 3 and the boundary surface 11 arranged with the usual bulk density coincide with a side surface of the recess 5.
  • This configuration increases the bending strength of the narrow section of the insulation board 1 above the recess 5, so that the risk of breakage is significantly reduced.
  • the boundary surface 11 is arranged slightly above the side surface of the recess 5, so that the above-mentioned advantageous effect is achieved here in addition to a high compressibility of the side surfaces of the recess 5 in order to accommodate webs to facilitate in the recess 5, the thickness of which is greater than the gap width of the recess 5.
  • the insulation board 1 is expediently installed in the cassette wall so that the oblique fiber structure can be subjected to pressure.

Abstract

L'invention concerne un panneau de matière isolante constitué de fibres minérales et destiné à isoler des murs extérieurs constitués de tôles profilées à section transversale en U se présentant en particulier sous la forme d'un profil en caisson, au moins une branche de la tôle profilée étant coudée au niveau de son extrémité libre et s'étendant ainsi sensiblement parallèlement à un élément de liaison reliant les branches de la tôle profilée. Ledit panneau de matière isolante se présente sous la forme d'un parallélépipède comportant deux grandes surfaces parallèles, espacées l'une de l'autre et reliées entre elles par des surfaces latérales perpendiculaires entre elles et auxdites grandes surfaces. Au moins une surface latérale comporte au moins une entaille destinée à recevoir la partie de la branche s'étendant parallèlement à l'élément de liaison. L'objectif de l'invention est d'améliorer lesdits panneaux de matière isolante de manière à éviter de façon particulièrement simple et appropriée que des déformations n'altèrent la stabilité dimensionnelle et par conséquent l'effet isolant des panneaux après leur fixation à l'ossature porteuse, et ceci dès leur fabrication. A cet effet, l'entaille est constituée d'un évidement (5) en forme de fente présentant une largeur permettant de recevoir l'élément de liaison coudé du profil en caisson, de manière à ce que la déformation des panneaux de matière isolante soit la plus faible possible.
