Definitions

  • the invention relates to a method for laying Gypsum fibreboards with a special edge formation butt using a suitable joint filler.
  • Gypsum fiber boards have been known for many years. she have a higher strength compared to plasterboard and directional independence for many Stress cases. They are therefore for certain Applications more suitable than plasterboard, for what however, a higher weight compared to plasterboard Purchase must be made.
  • the known gypsum fiber boards always have one right-angled edge and must be laid at a distance become.
  • the resulting joint is made with a Filled filler, which with regard to the Tensile strength and bending tensile strength of the filled joint is of particular importance.
  • the object of the invention is a method for laying of gypsum fibreboard with a special To provide edge formation, which is a faster Lay the joint if the joint is sufficiently firm individual plates guaranteed with each other.
  • This task is solved by a procedure for Laying gypsum fiber boards with at least one of these chamfered plate edge that the chamfered edge one Bridge perpendicular to the plate surface whose height is 5 to 50% of the plate thickness, at least 1 mm, and the chamfer width at least 3 mm is, where the plates are butted and the resulting joint spaces filled with a joint filler, of 70 to 98% by weight of stucco with a particle size of ⁇ 300 ⁇ m, 0.02 to 0.5% by weight thickener, 0.2 to 1% by weight Water retention agent, 0.5 to 3% by weight polyvinyl alcohol and 0.001 to 0.1% by weight boric acid or an alkaline earth or alkali salt of boric acid, each based on the Weight of the mixture, as well as usual additives.
  • a method for easy laying of the gypsum fibreboard on butt and at desired firm bond between such plates allows.
  • EP 227 876 B1 describes plasterboard with a rounded edge and a joint filler for the joint spaces specially formed with these panels. Gypsum plasterboards are usually lighter than Gypsum fibreboards of the same thickness.
  • EP 0 094 507 A2 discloses a board wall made of plasterboard, which have a rounded edge and at least according to the Figure to be laid on butt.
  • U.S. 3,935,049 describes laminates made of plasterboard and resin-soaked Papers with rounded edges, with the edges through protected a strip of thermosetting resin are. To produce these laminates, the Starting materials pressed using heat.
  • EP 0 458 328 A1 relates to a thickener system for water-containing building material mixtures.
  • plasters, adhesives and fillers called.
  • a filler is applied Plaster base described, whose composition is essentially the of the joint filler used according to the invention.
  • EP 0 303 071 A1 relates to one Joint filler for grouting plasterboard joints.
  • the DE 43 31 141 A1 describes a joint filler which especially for filling the joints of Plasterboard is suitable.
  • the chamfer of the gypsum fibreboard must be designed in this way be that the web height of the gypsum fiber board edge 5 to 50% of the plate thickness, but at least 1 mm. is the web height is less than 5% of the panel thickness or less than 1 mm, the edge can be used during chamfering, transport or installation break off the gypsum fibreboard.
  • the jetty is much higher than 50% of the plate thickness Joint space too small and that for filling the joint usable amount of joint filler is not sufficient that to ensure the desired joint strength.
  • Multi-layer gypsum fibreboards have a core layer and at least one top layer.
  • the thickness of the Core layer can be 25 to 50% of the gypsum fiber board thickness turn off.
  • the edge should be chamfered so that the chamfer or the fiber leg straight, concave or convex is.
  • the edges can be factory or on site be chamfered with a hand tool.
  • the main ingredient is a ⁇ -hemihydrate gypsum (stucco), due to the manufacturing process, small amounts of others May contain calcium sulfates.
  • the plaster is in a lot of grout mix from 70 to 98% by weight, preferably 90 to 97% by weight.
  • a starch ether is preferably used as the thickener used. Starch ethers are particularly preferred Hydroxypropyl. These thickeners are in one Amount of 0.02 to 0.5% by weight, preferably 0.1 or 0.2 up to 0.3% by weight.
  • As a water retention agent methyl celluloses are preferably used. The Water retention agent is used in an amount of 0.2 to 1% by weight, preferably 0.5 to 0.8% by weight.
  • Dry joint filler mixture to be used according to the invention Polyvinyl alcohol and boric acid or an alkali / alkaline earth salt a boric acid. Boric acid and its salts promote the crosslinking of polyvinyl alcohol and increase the strength of the joint filler and the adhesive strength of the joint filler on the gypsum fibreboard.
  • plaster-bound joint fillers include common additives Retarders, accelerators, wetting agents and defoamers.
  • a protein retarder for example in an amount of 0.01 to 0.5% by weight.
  • the accelerator can be used in an amount of 0.1 to 1% by weight. be used, especially if it is a dihydrate accelerator.
  • a wetting agent can for example in amounts up to 0.1% by weight Defoamers are used in an amount of up to 0.2% by weight become.
  • the joint filler mineral aggregates such as Limestone powder (calcium carbonate), mica or mixtures contain individual mineral aggregates. This are preferably in an amount of up to 25% by weight in the dry joint filler mixture.
  • Blend a polyacrylamide or polymethylacrylamide add.
  • the amount of this additional thickener depends on the desired viscosity and can be up to 0.1% or more, preferably up to 0.06% by weight.
  • the viscosity and viscosity of the joint filler can be affected by Addition of fibers, in particular cellulose fibers, further to be controlled.
  • Cellulose fibers can for example the dry joint filler mixture in quantities up to 1 % By weight are added.
  • the joint filler used in the invention is dimensionally stable and elastic, so that neither crack nor Bead formation are to be expected.
  • the in the association of comparatively heavy gypsum fiber boards by external Stresses occurring through the joint added without this adversely affecting the joint effect.
  • the dry is used to fill the joint Joint filler mixture in a known manner with water stirred.
  • a relationship has proven to be practical Water / dry grout mixture of about 0.9 proved.
  • the two figures show two different ones Embodiments of the edge of the invention Gypsum fibreboard 1.
  • the chamfer 2 or fiber leg 2 can just as in Fig. 1 or convex or concave as in Fig. 2 indicated, be formed.
  • the remaining one right-angled web 3 of the edge enables laying of the gypsum fibreboard on impact.
  • the depth of the chamfer is with the angle between the imaginary extension of the web 3 and the bevel leg 2 for the joint volume and thus the The amount of joint filler that can be inserted is responsible.
  • a joint filler according to the invention is produced on the basis of the following recipe. 92% by weight Stucco, particle size ⁇ 300 ⁇ m 4.27% by weight limestone 0.5% by weight cellulose fibers 0.2% by weight starch 0.8% by weight methylcellulose 0.7% by weight Dihydrate accelerator 0.02% by weight polyacrylamide 0.01% by weight borate 1.5% by weight polyvinyl alcohol 0.01 to 0.2% by weight retarder
