Definitions

  • the invention relates to a method for producing a multilayer, heat-insulating and fire-retardant composite panel, in which at least one layer consists of a panel made of pressed mineral wool.
  • the invention further relates to a composite panel produced by the method.
  • the suspended ceiling must have fire protection of class F30 - F90 so that the steel girders that are installed in or form the solid ceiling are not attacked by a fire that breaks out in the room.
  • gypsum cassette panels So far, they had managed to use gypsum cassette panels, for example. However, a higher fire protection class than F30 could not be achieved.
  • the gypsum cassette panels are very good heat conductors, which is undesirable for thermal reasons; for this reason had to be designed n in the suspended ceiling structure still mineral fiber webs may be applied vapor barrier.
  • the object of the present invention is to develop a composite panel of the type mentioned at the outset in such a way that there is a substantially improved fire safety with at the same time improved thermal insulation capacity, the advantage of a much simpler and less expensive assembly being achieved.
  • a composite panel produced by the process is characterized in that the composite panel consists of two plate elements made of rock wool, glass wool or basalt wool, the plate elements being separated by a reflective film in the area of their horizontal contact surface, and the reflective film on both sides with a highly heat-resistant glue layer each with the associated one Plate element is connected.
  • the mineral wool board elements on their own do not have good fire resistance. If you wanted to use such mineral fiber board elements in residential construction, a relatively good thermal insulation would be given, but not the required fire safety, because the phenol glue, which connects the mineral fibers of a board element, decomposes at 600 ° C.
  • the reflective tape consists for example of an aluminum foil or another metal foil, but it can also consist of a silver-damped plastic foil or the like. It is only important that this aluminum foil withstands temperatures of up to approximately 1000 ° without substance destruction.
  • the reflective tape acts as a vapor barrier, i.e. hot air or moist air cannot pass through the plate, this also protects the back.
  • the lamination disintegrates at the high temperatures of about 1000 o and the plate elements fall apart.
  • a glue layer be applied to the front and back of the reflective film as the connecting element and that this glue layer consists of a water glass glue.
  • the basic substance is a powder mixed with water is stirred, and which has a slightly yellowish, glass-like transparent appearance when ready for use.
  • This glue is then applied and dried and results in a very hard and brittle connection layer after drying.
  • this glue layer acts as a protective screen for the reflective film and this glue layer protects the reflective film from heat decomposition.
  • this water glass glue has approximately the same expansion capacity and similar brittleness behavior as the reflective film, so that both materials complement each other. This protects the reflective film from warping, and the glue layer forms a protective screen that surrounds the reflective film on both sides (on all sides).
  • the glue layer penetrates the fibrous substance of the plate elements on the connecting layer and keeps the plate elements with high strength connected to the glue layer and the reflective film.
  • the required high level of fire safety is also achieved by inserting a reflective tape in the structure of the composite panel.
  • the upper plate element is completely kept free of gas heat flows (convection), and the reflective film still radiates a large amount of heat back into the lower plate element, so that the required high level of fire safety is provided.
  • the reflective tape offers a high degree of mobility, in addition to the glass-hard water glass glue. This prevents the glue layer, which is very brittle, from flaking off, tearing open and forming cracks, so that this creates an undesired heat transfer. Furthermore, the connection between the plate elements, which consist of a mineral fiber wool material, is very soft, so that thermal stresses can be absorbed well without the glue layer being attacked.
  • the advantage of the invention is that high heat insulation is ensured in the same part, that is, the same composite panel, so that the cumbersome rolling out of mineral fiber mats with a built-in vapor barrier, as was previously the case with plaster cassette ceilings, can be omitted.
  • a vapor barrier is installed in the form of the reflective film.
  • suspension profile can either engage with its horizontal leg in a groove within the lower panel element (concealed construction), or the visible side of the composite panel can be placed on the horizontal leg (visible installation of the suspension profile).
  • jacket elements which have a support beam, e.g. Enclose steel or wooden beams.
  • a support beam e.g. Enclose steel or wooden beams.
  • Another field of application of the proposed composite panel elements is the creation of facing shells for walls or of self-supporting partition walls in residential and industrial buildings.
  • the reflective film 4 has a thickness of approximately 4/100 mm.
  • the glue layers 5 have a thickness of about 50/100 to 1 mm, the thickness cannot be determined exactly and is only indicated schematically with reference to FIG. 1, because the glue layers 5 extend into the area of the fibrous plate elements and form a transition area there, so that the thickness can only be given approximately.
  • the composite panel element 1 shown in Fig. 1 has a particularly simple construction on the visible side 9, which also contributes to the fact that fire safety is increased by a further, essential degree. Tests by the applicant have shown that the visible side of the composite panel can be provided directly with a highly heat-resistant color layer 7.
  • a layer of paint is e.g. a layer of lime paint (sludge from burnt lime suspended in water).
  • the coloring layer 7 of lime has the advantage that it is highly heat resistant, and can withstand temperatures of about 1000 0 C without change, ie there will be no color changes or material changes. But if you want to improve the fire safety of such a plate element even more, then you have to achieve an airtight seal on the visible side 9 ago.
  • the fire safety class F90 means that such an element must withstand a temperature of 1000 ° C. on the visible side for 1 1/2 hours without the plate element being decomposed, with only 400 ° C. on a steel beam on the back of this plate element and only 200 0 C may occur on a wooden structure.
  • Fire safety class F120 means that the same conditions mentioned above are maintained for 2 hours.
  • the visible side 9 of the composite panel element then shows the color layer 8, which is mixed with water glass is applied, this color layer can be colored as desired, and it can be applied in any structure.
  • the fire is affected in the direction of arrow 10.
  • Fig. 1 also shows a special suspension construction.
  • the composite panel elements 1 can be placed directly on a suspension profile 23, on one side of the horizontal leg 24, with a hanging strip 26 being arranged on the vertical leg 25, which has corresponding recesses into which the ceiling hooks are hung.
  • connection or the support of the composite panel element on the horizontal leg 24 can be described as tight.
  • FIG. 2 shows that the top layer 6 of the composite panel element 1 consisting of the color layers 7, 8 can also be constructed differently.
  • FIG. 2 shows a composite panel element 20 which carries a decorative panel 22 instead of the cover layer 6.
  • This decorative plate 22 is in turn glued to the visible side of the lower plate element 3 with a glue layer 19 made of water glass glue.
  • the decorative plate 22 can consist of different materials. It is possible to use a thin chipboard as the material.
  • the chipboard has a thickness of 4 mm, it can consist of a chipboard or a veneered chipboard.
  • the decorative plate can also consist of a metal plate. In a fire test, the decorative panel would then carbonize (if it is made of wood), but this has no influence on the fire resistance of the composite panel element 20. It should also be noted that the glue layer 19 during the exposure to heat Protective screen function, and the conditions previously described in relation to the reflective film 4 and the glue layers 5 applied therein still remain.
  • the composite panel element 20 of Figure 2 can be used with the same suspension system as that of Figure 1, i.e. the horizontal leg 24 could be visible from below.
  • Figures 4, 5 and 6 to 10 show the details of a suspended ceiling construction using the designated composite panel elements 1 or 20.
  • the composite panel elements 1 are offset from each other in the association with the end joints.
  • wall brackets 260 are attached, on the horizontal leg of which the composite panel elements 1 rest.
  • the wall brackets 260 can be fastened to the wall via corresponding fastening brackets 203.
  • the joints of the composite panel elements 1 lie on the horizontal legs of ceiling profiles 201.
  • the vertical leg of the ceiling profile 201 has recesses (openings) arranged at a distance, through which the vertical profile of a cross profile 202 is pushed.
  • This cross profile 202 is thus arranged perpendicular to the longitudinal profile of the ceiling profile 201 and supports the composite panel elements at their longitudinal joints, while the cross joints are carried by the ceiling profile 201. In this way it is possible to use large format composite panel elements, for example in the format 125 x 62.5 cm.
  • Bores are arranged in the vertical part of the ceiling profile 201, through which the hook of a suspension wire 220 engages and which is inserted into a clamping spring 211 according to FIG. 10 for the purpose of length adjustment.
  • the length of the suspension hook 220 can be infinitely adjusted by compressing the resilient legs of the clamping spring 211.
  • the other side of the suspension hook 220 is hung with the bent part in an eyebolt 250, which in turn is screwed into a brass dowel 251 screwed into the solid ceiling 13.
  • the ceiling supports 11 arranged in the space between the solid ceiling 13 and the suspended ceiling are only subjected to the influence of heat as described above. An extraordinarily high fire retardancy is therefore achieved.
  • FIG. 11 Another area of application is shown in FIG. 11.
  • the jacket element 15 shown there serves for the full-surface coating of horizontal or vertical supports.
  • the individual plate elements 16, 17, 18 are each connected to the reflective film 4 at their contact surfaces via glue layers 5.
  • the reflection film can also be arranged in the interior 30 of the jacket element 15 on the surfaces of the plate elements facing the interior.
  • the reflective film 4 is also arranged on the outside of the plate elements.
  • This outside is additionally covered by a jacket covering 31, which can consist of a decorative plastic film, a fabric or another decorative covering. It is important that the effect of fire from the outside of the casing element 15 is certainly prevented from the interior 30.
  • the plate elements 16, 18 are separated from one another by a miter cut 29, the miter cut 29 merging into step-shaped undercuts 28. In this way, an airtight seal of the plate elements 16, 17, 18, 27 is achieved, especially since the connecting surfaces are covered with the reflective film 4 via glue layers 5.
  • the entire jacket element can be held together by a screw connection 33, a parting line 32 of the jacket covering 31 being arranged in the region of the screw head so that the head of the screw is accessible from the outside.
