Definitions

  • the invention relates to a method for the construction of a ceiling or wall of material panels.
  • Material plates according to the invention are in particular gypsum material plates, calcium silicate plates, fiber-doped calcium silicate plates, cement-bound fiberboard, normal and lightweight concrete slabs, cement-bonded slabs with lightweight aggregates and wood-based panels.
  • gypsum material plates calcium silicate plates, fiber-doped calcium silicate plates, cement-bound fiberboard, normal and lightweight concrete slabs, cement-bonded slabs with lightweight aggregates and wood-based panels.
  • such boards may in particular be coated with wall paints, varnishing paints, gypsum plaster, plaster, lime plaster, lime or gypsum putty, glazes or dispersion putties.
  • Gypsum-based panels are distinguished in gypsum plasterboards and gypsum fibreboards.
  • a sandwich with cardboard layers is formed as a cover layer membrane.
  • the board surface is homogeneous and smooth so that it no longer has to be calibrated and tempered.
  • gypsum fiber boards are monolithic bodies and have a rough surface which can not readily be used as a visible surface.
  • Calcium silicate boards are used as cladding for fire protection and in the rehabilitation area as Sanierplatte. The surface is usually rough. It can not be used as a visible surface without editing.
  • Fiber cement and lightweight panels also have a rough surface due to their production, which must be reworked when used as reformfikiee.
  • Normal and lightweight concrete slabs are used as element ceilings and walls. These are reinforced concrete slabs, where joints are caused by installation. which must be reworked without cracks on the element joints for use as a visible surface.
  • Gypsum material and wood-based panels are hygrisch or thermally or in interaction of both causes conditional changes in shape. They disappear or expand. Thermally induced changes in shape are relatively small in gypsum material boards. The hygrisch caused change of shape predominates. In this case, the case of shrinkage during and after the construction phase of the slabs prevails because they are exposed to a higher equilibrium moisture content and are conditioned to a lower equilibrium moisture content in the utilization phase. In damp rooms, there are also alternating stresses. In any case, the butt joints of the gypsum material plates are subjected to dynamic loads.
  • Calcium silicate, fiber-doped calcium silicate, fiber cement and lightweight concrete slabs are subject to hygric, crystalline and thermal or due to the interaction of these causes conditional change in shape. Likewise, changes in shape can occur as a result of carbonation processes and associated microstructural changes. The hygrisch caused changes in shape are low in these plate types. The shape changes from crystalline water rearrangement and thermal change of shape over weigh.
  • the sheet metal profiles can easily twist during installation. This creates an offset in the alignment of the building panels.
  • the flange of the profiles can bend inwards at their free edge if the screw for fixing the plates does not immediately cut into the sheet and the pressure in the screw axis leads to a plastic deformation of the flange. Again, there is an offset in the alignment of the building panels (flatness).
  • the joint offset can be compensated by a HRAK edge (half-round flattened edge) or at least an AK edge (flattened edge), which allows a polygonal extension of the putty surface of the butt joint, so that the stripping no longer visually appears.
  • HRAK edge half-round flattened edge
  • AK edge flattened edge
  • plasterboard In order to produce surfaces of as good a quality as possible with plasterboard, various measures are taken. Thus, the plasterboard, as er ⁇ imagines, trained with HRAK or AK edges to take the filler from gypsum for filling the joints.
  • the joint filler is applied with considerable amounts of material in several operations, since the spatula naturally fades (if the above and below is referred to as spatula, actually putty is meant, which are according to DIN 55945 highly filled and pigmented pigmented coatings, which predominantly be used for filling pores and Aus ⁇ equality of unevenness of substrates).
  • the spatula joints can be seen in the grazing light when viewing the surface. If this is not the case, a special fine putty can be applied over the whole area with a suitable putty tool.
  • the sticking to the substrate has a disadvantageous effect on the crack-free surface, since stress concentrations due to the obstruction of the plate movement occur. Since the plates are mounted on a wood material, such as OSB, the joints in a suitable strip, for. B. of paper, deposited to prevent the so-called three-dimensional adhesion. This measure is complicated and less economically.
  • Another disadvantage of the bonding of gypsum fiber boards is the high tensile strength of the compound. As a result, the movements and stresses of the individual plates add up. The result is a kinematic chain, through which the bond is subjected to a high force of constraint, since the Reibungs ⁇ resistors of the support structure are too large. If the load becomes too great, the crack will be visible to the human eye.
  • the paper joint cover strip is rigidly embedded in the AK or HRAK joint with putty.
  • These paper joint tape strips have the disadvantage that they change their shape under the action of subsequent aqueous coatings (primer, paint, putty). When embedding they swell up and after curing the putty they disappear.
  • lattice joint strips are used, which achieve similarly good joint tear strengths, provided that the filler is carefully pressed into the joint during filling.
  • the invention has for its object to provide a method for the construction of a ceiling or a wall of material plates, with the unaufwen ⁇ Dige way a high-quality surface is created.
  • the Werk ⁇ material plates are dull (crunchy) juxtaposed.
  • a paper tape with a width of 3-8 cm is glued over the two plates.
  • the strength of the paper tape and the adhesive are such that when a broadening of the joint, the stresses occurring in the paper tape shears the adhesive bond near the joint rather than tearing the paper tape.
  • the adhesive causes sufficient elasticity such that sliding is more likely to occur than tearing of the paper tape. Since the paper tape would tear due to the high notch stresses on shrinkage of the plate, the adhesive used must possess a gap-filling property. This is done by adding fillers as putty or putty with a small Schwundmaschine. Fillers according to one embodiment of the invention include color pigments such as titanium dioxide or talc or both in combination. In addition, fillers such as terra silicea purificata cause the sanding ability of the adhesive, which can eliminate processing errors when applying the adhesive.

  • the perforation of the plastic coating is also advantageous in the case of a tape of the type specified. In this way, sufficient adhesion is achieved perpendicular to the plate plane. As in the case of the coating of the paper tape, this again took place in the middle of the specified tape in a width of up to 40 mm.
  • the plastic coating reduces the adhesion on the plate surface parallel to the plate plane in the middle area. By increasing the expansion surface up to about 40 mm, a significant improvement in the absolute extensibility is achieved with unchanged expansion properties of the nonwoven used.

Abstract

L'invention concerne un procédé pour ériger un plafond ou une paroi à partir de panneaux, en particulier des panneaux de gypse, selon lequel les panneaux sont fixés à une structure de support par vissage, clouage, agrafage, ou collage sur une construction support ou collés directement sur la base par collage par points ou collage par face. L'invention est caractérisée en ce que les panneaux sont placés les uns contre les autres bord à bord (sans grincement) ; une bande fine de papier de largeur (3 à 8 cm) est collée sur le joint des panneaux adjacents au moyen d'un adhésif ; l'adhésif est flexible de manière élastique, et lors d'un rajout de produits de remplissage, l'adhésif se présente sous la forme d'une masse coupante ou de ciment présentant une faible mesure de contraction ; et la résistance de la bande de papier et de l'adhésif relié aux autres adhésifs est conçue de sorte que lors de l'élargissement du joint, les contraintes apparaissant dans la bande de papier entraînent les adhésifs reliés à proximité des effets du joint ou l'adhésif relié effectue un cisaillement-coulissement, lors que la bande de papier se déchire.
