  • a carrier shell consists of one or more steel sheets and roof insulation panels on top of them. Roof insulation panels made from mineral fibers, preferably from rock wool, have proven particularly suitable for this.
  • roof insulation boards made of mineral fibers have about 3 - 7% by mass of a thermosetting curing mixture of phenol-formaldehyde-urea resins, with which the mineral fibers are bound in a known process of melting, defusing and gathering together a silicate starting material.
  • binders which amount to a maximum of 4.5% by mass in the most frequently used mineral fiber products in this area of application, naturally not all mineral fibers can be adequately bound or the majority of the mineral fibers will only be linked to one another at points, in addition to obtain a resilient behavior of the mineral fiber mass.
  • the individual mineral fibers are covered with oil films during the manufacturing process in order to prevent capillary activity of the insulation material and the failure of condensation in the insulation layer.
  • the structure and orientation of the individual mineral fibers in the roof insulation panels, as well as the bulk density, can be varied within relatively wide limits.
  • the mineral fibers wetted with binders and made hydrophobic are produced on an air-permeable collecting belt as a mineral fiber web under the slightly compressing line, usually formed by one or more continuous conveyors, for example conveyor belts and / or roller conveyors Effect of a cooling and transport air sucked through in a quasi natural position.
  • the endless mineral fiber web is then compressed and the binder is cured in a hardening furnace before the mineral fiber web is then divided into individual sections that form the roof insulation boards.
  • properties are small-format by using, for example, 1 to 1, 25 m long and 0.5 to 0.625 m wide
  • the upper insulation cantilevered sections of the roof insulation panels are very quickly damaged or destroyed in use if they are not at least based on stable vapor and air barriers
  • Bitumen sheets are glued or laid out.
  • the roof insulation panels used for this purpose have a special structure.
  • First, natural fluctuations in the mineral fibers produced per unit of time and fluctuations in the deposition of the mineral fiber mass are greatly reduced by the fact that the thinnest possible, so-called primary fleece is deposited in the desired thickness by pendulum movements on a second conveyor belt and then an endless mineral fiber web formed in this way, called secondary fleece, into Unfolding facility is promoted where the mineral fiber web (secondary fleece) is subjected to an intensive longitudinal and simultaneous height compression.
  • the consequences are intensely deformed with each other in the direction of production and therefore in the direction of conveyance, and steep with the big ones
  • the secondary fleece has an apparently laminar structure.
  • the secondary fleece then passes through a hardening furnace, possibly after further mechanical processing stations, such as compression areas, in which the binder is hardened and the geometry of the secondary fleece is fixed. After leaving the hardening furnace and a downstream cooling zone, the secondary fleece is trimmed using circular saws arranged parallel to the direction of production. A strip of secondary fleece that is several centimeters wide and previously compressed laterally is separated, which also gives the saw a certain amount of guidance.
  • the fixedly positioned saws equipped with large-sized saw blades usually produce two parallel longitudinal surfaces, which run parallel to the conveying direction and thus along the secondary fleece. In order to achieve the most parallel alignment of the longitudinal surfaces, the axis of the saw blades must be exactly aligned.
  • the saw blade axis can easily deviate from the horizontal axis, so that the longitudinal surfaces are not parallel to each other and / or not exactly at right angles to the large surfaces of the roof insulation panels to be formed from the secondary fleece.
  • These roof insulation panels are separated from the endless secondary fleece according to the desired width by cross saws with saw blades.
  • the particularly large, coarse-toothed circular saw blades of the cross saws are constantly driven because of their mass and cooling.
  • a measuring device determines the current conveying speed of the secondary fleece and controls a drive moving the saw in the conveying direction with the conveying speed of the secondary fleece. In the area of the desired cut, the cross saw is pushed through the secondary fleece at a feed rate of several meters per second across the conveying direction.
  • the accuracy with which the area of the separating cut is to be controlled is of the order of magnitude of + 2 mm, in addition there are deviations from the perpendicularity of ⁇ 1.5 - 2.5 mm per 2 m width of the secondary fleece.
  • Such a precise control of the cross-section cannot be achieved with the known systems and controls, which is also reflected in the level represented by the applicable standards.
  • the roof insulation panels separated from the secondary fleece are then stacked on top of each other without further treatment, e.g. stacked on transport pallets and covered with plastic sheeting to protect against the weather.
  • the roof insulation panels are preferably produced as large-format elements with dimensions of, for example, 2 m in length and 1, 2 m in width and approximately 40 to 160 mm in thickness.
  • these roof insulation boards can be transported and installed much faster and, on the other hand, react to loads on their large surfaces like multi-span girders and are therefore more resistant from the outset than small-format roof insulation boards.
  • the steep arrangement of the individual fibers also leads to a reduction in the punching resistance of the area of the roof insulation panels arranged between the upper chords of the profiled support shell.
  • roof insulation panels described above has one to avoid in particular the low punching resistance integrated top layer with mineral fibers that are particularly highly compressed to approx. 180 to 220 kg / m 3 .
  • roof insulation panels made of mineral fibers are very stiff in themselves, so that the edge areas cannot be compressed, or only very slightly, when laying.
  • the roof insulation panels are laid offset on the support shell.
  • Roof insulation panels with particularly direction-dependent bending tensile strengths are usually designed with their longitudinal axis transverse to the profile direction of the support shell, that is to say transversely to the upper chords and thus also to a lower flange of the support shell arranged between two upper chords. Tolerances in the width of the roof insulation boards, like the skew angle in relation to the dimensions, therefore lead to gaping joints in the insulation layer.
  • the gaping joints represent thermal bridges, which significantly reduce the insulating effect.
  • the individual sheets of air-blocking foils are usually not glued tightly to one another and are also not tightly connected to the adjacent components, warm air can in principle always flow from inside the building through and above the foils that often sag over the lower chords, and ultimately without further resistance between them Roof insulation boards get into the spaces between the insulation layer and loose roof seals. Condensation forms immediately on the underside. If this cannot evaporate again quickly and diffuse outwards via the roof seals, the roof insulation panels become wet, which not only significantly reduces their insulating effect, but also leads to significant reductions in strength and corrosion of the fastening elements, namely the screws and plates.

  • roof insulation panels In order to avoid open joints between the individual roof insulation panels, no or only very slight deviations from the nominal values of the Dimensions and the right angles occur at the corners of the roof insulation panels. In addition, larger roof areas are installed roof insulation panels that were manufactured at different times and, if necessary, in different production plants. According to the invention, roof insulation panels with deviations in the width of approx. ⁇ 0.5 to 1 mm or a skew angle of max. about 0.5 to 1 mm per meter in terms of lengths and widths. These tolerances exclude the disadvantages mentioned at the outset at least to the extent that joints between adjacent roof insulation panels are designed to be so small that no thermal bridges are formed.

Selon ce procédé, on produit à partir d'une masse de silicate en fusion des fibres minérales que l'on dépose, associées à un liant et/ou un agent d'imprégnation, sur un convoyeur continu sous forme de bande de fibres minérales. Cette bande de fibres minérales est soumise à des traitements mécaniques puis cédée à un four de trempe et enfin subdivisée en plaques le long de surfaces de coupe. L'invention concerne également un dispositif de production de plaques isolantes de toiture et de mise en oeuvre du procédé, avec un parcours le long duquel les plaques isolantes de toiture sont transportées jusqu'à une station d'emballage. L'invention vise à créer un procédé et un dispositif qui permettent la production simple et économique de plaques isolantes de toiture d'une grande précision dimensionnelle. A cet effet, les plaques sont disposées sur le convoyeur continu avec une grande précision tant en longueur qu'en largeur, leur longueur et leur largeur étant perpendiculaires. Le petit côté des plaques de toiture est rogné de telle manière que les plaques isolantes de toiture aient un écart maximal dans leur largeur de +/- 0,5 à 1 mm et/ou un biais maximal entre les surfaces de coupe et les surfaces longitudinales de 0,5 à 1 mm, pour une longueur de 1 m. Une butée qui est implantée sur le parcours de manière à pouvoir être introduite dans la voie de parcours, est dirigée perpendiculairement à la direction de transport. Un équipement d'usinage par découpe et/ou enlèvement de copeaux des surfaces latérales des plaques isolantes de toiture est implanté en aval de la butée, ces surfaces latérales étant sensiblement parallèles à la direction de transport.
