Definitions

  • the invention relates to a method for producing an insulating material from mineral fibers, in particular bonded with binders rockwool fibers, which insulating material consists of a fiber mat with attached on at least one large surface mesh fabric, wherein the fiber mat is made of a binder impregnated with fiber mass, the mesh fabric the pulp is sewn or quilted and the pulp is compressed at least in its longitudinal direction prior to sewing or stitching the mesh.
  • thermal insulation of buildings insulating materials, for example, in the form of insulation boards glued to the exterior walls of the building and then covered with a plaster, which usually consists of two layers of plaster and optionally embedded in the plaster layers reinforcement of fiber mats.
  • a plaster which usually consists of two layers of plaster and optionally embedded in the plaster layers reinforcement of fiber mats.
  • thermal insulation are referred to as thermal insulation systems.
  • the proof of the plaster layer is usually in the lower, directly on the insulating material resting plaster layer, the probation consists for example of an elastic mesh fabric, which is mostly made of endless glass fibers.
  • the maximum weight of a coat that can be applied is approximately 32 kg / m 2 .
  • the total self-weight of a thermal insulation composite system is limited to about 60 to 65 kg / m 2 . Higher inherent weight occur, for example, when ceramic plates form the outer end of the thermal insulation composite system.
  • Polystyrene rigid foam boards are used as the insulating material, which at high densities between 15 and 30 kg / m 3 have a high compressive, shear and transverse tensile strength. Hard foam boards of this type must first be secured with so-called insulation holders at high wind loads, which are anchored in the supporting outer wall via molded dowels. But since polystyrene rigid foam panels are normal or easily inflammable, they have for tall buildings are not approved and, due to the latent fire risk on low buildings, should only be used in conjunction with certain fire risk reduction measures.
  • mineral wool insulating boards are also known as insulating materials, which can have significantly different structures and therefore large differences in the strength properties.
  • Mineral wool insulating materials are also used in thermal insulation composite systems in sheet form, such insulation boards with densities of about 120 to 150 kg / m 3 transverse tensile strengths of about 15 to 25 kPa and compressive stress values of more than 40 kPa at 10% compression can have.
  • a fiber flow is substantially parallel to the large surfaces of the insulation boards.
  • such insulating panels are known in which the fibers are predominantly oriented perpendicular to the large surfaces.
  • Such insulating panels have already at gross densities from 90 kg / m 3 transverse tensile strengths of more than 80 kPa.
  • the shear stress values of both different insulation boards are in the range of approx. 50 to 20 kPa.
  • Insulating materials made from mineral fibers lose their strength during intensive and long-term exposure to moisture, so that when calculating the stability of thermal insulation composite systems only relatively low fatigue strength values can be used in conjunction with relatively high safety coefficients. Consequently, insulation boards with a fiber path parallel to their large surfaces must always be secured with insulation holders, although it has been found in practice to be common to glue the insulation panels with at least 40% of their surface area with the substrate. In insulating panels with a grain perpendicular to the large surfaces in certain areas sticking of the insulation boards on the substrate is sufficient, so that can be dispensed with buildings up to a maximum height of, for example, 20 m insulation holder. Only in areas of particularly high wind load must then be additionally anchored insulation holder in the ground.
  • the number of insulation holders depends on the wind suction load and the size of the insulation panels. In general, four to six insulation holders per square meter are arranged in the wall surfaces, while the number is raised in the edge regions of the facade to eight to twelve Dämmstoffhalter per square meter, since experience shows that there is a higher wind load in edge regions.
  • the insulation holder consist of a mostly circular plate, which is broken for uniform embedding in the plaster layers. On this plate, a hollow shaft is formed, which usually expires in a Sp Dahldübel. Plate, shank and expansible plug are made of a tough plastic, usually made of polyamide, fiber-reinforced polyamide, or other fiber-reinforced plastic.
  • the diameter of the often circular plate is about 60 to 140 mm and may vary within the building insulation, so that, for example, find in the peripheral areas plate with a larger diameter to achieve greater strength.
  • the insulation holder can either be placed directly on the surface of the insulating material, so that the maximum resistance to wind suction is determined depending on the tensile strength of the plate by the insulating material, or be mounted only after the application of a first layer of plaster, the force is much cheaper, since in this procedure, the reinforcement fabric, which is generally arranged in the first layer of plaster, contributes substantially and the anchor penetration resistance increases significantly.
  • the Dübel malzugsfesttechnik or fürzugfesttechnik by the insulating material is particularly by the Scherfestikgeit the insulating material and the Shape stability of the insulation holder influenced.
  • the through-pull is lower in insulating panels with fibers oriented at right angles to the large surfaces than in panels of insulating material whose fiber orientation is oriented essentially parallel to the large surfaces.
  • the insulation holders are considered as statically easily calculable cantilever arm on which the insulation material hangs together with the plaster and outer layers, or absorbs the forces arising as a result of hygrothermal deformations and wind loads and dissipates into the load-bearing wall.
  • the anchoring methods of the insulation holder described above are relatively expensive.
  • the insulation panels In order to achieve the necessary strength properties, the insulation panels must have a minimum raw density, due to the manufacturing processes, no complete binding of all fibers can be achieved, ie that the insulation panels can have weaknesses that adversely affect the strength, especially in view of the here significant transverse tensile strength ,
  • the anchoring methods of the insulation holder require drilling holes and arranging the insulation holder.
  • the Dämmmaterialdicken required from 250 to 300 mm, a greater number of Dämmstoffhaltern must be installed with the associated higher strength values the like, which then increasingly reduce the thermal resistance of the thermal insulation composite system because of their effect as a thermal bridge.
  • the plaster layer thicknesses are reduced to 6 to 8 mm in order to save material and labor costs.
  • the plates are characterized in the plaster layer, which is the case especially in certain climatic conditions and deteriorates the appearance of the facade due to usually irregular positioning.
  • Such a method is known from US-A-5 981 024, which produces a cured mineral fiber nonwoven web, wherein in a first step a first mineral fiber nonwoven web is produced having a first longitudinal direction parallel to the first mineral fiber web and a first transverse direction parallel to the first Mineral fiber web defines which first mineral fiber web predominantly contains mineral fibers disposed generally in the first longitudinal direction thereof and includes a first curable binder. This first mineral fiber web is moved in the first longitudinal direction.
  • the first mineral fiber web is disposed in segments in partially mutually overlapping fashion transverse to the first longitudinal direction to produce a second mineral fiber nonwoven web, the second mineral fiber web defining a second longitudinal direction and a second transverse direction predominantly generally to the second longitudinal direction and the second transverse direction and generally contains mineral fibers arranged transversely to each other.
  • the second mineral fiber web is then moved in the second longitudinal direction and folded transversely to the second longitudinal direction and parallel to the second transverse direction to produce a third mineral fiber nonwoven web, the third mineral fiber web predominantly transverse to each other and generally transverse to the second longitudinal direction and the second transverse direction Contains mineral fibers.
  • This third mineral fiber nonwoven web is moved in the second longitudinal direction and the first curable binder is cured so as to cause the mineral fibers of the third mineral fiber web to bond to each other, thereby forming the cured nonwoven mineral fiber web. It is preferably provided that an additional step of the longitudinal compression of the second mineral fiber web is carried out.

  • the mortar carrier is formed as a sheet and has a fiber structure of in particular a natural or synthetic fiber fabric or non-woven fabric.
  • the spacer element is a three-dimensional space element, which is wave-shaped, zigzagged or sickle-shaped and consists of a plastic or metal structure.
