Definitions

  • the invention relates to a plasterboard with a special edge formation as well as one for the educated Joint 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 Load 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.
  • a disadvantage when using known gypsum fibreboards and joint filler used for this is that when laying the Plates must be made sure that the laying the plates are made in a certain grid dimension and a Constant distance of about 5mm between the plates is observed.
  • Well-known gypsum fiber boards are not laid on butt, what the laying of the panels would greatly simplify.
  • the object of the invention is to develop a system To provide gypsum fiber boards and a joint filler, which is a quicker laying with sufficiently firm Joint connection between the individual panels guaranteed.
  • a gypsum fibreboard that has at least one chamfered edge, the Chamfered edge at a right angle to the surface of the board has standing bridge, the height of 5 to 50% of Board thickness, but at least 1 mm, and the chamfer width is at least 3 mm, and a joint filler for Filling the by the laid on butt Gypsum fibreboard resulting joint spaces, the 70 to 98% Stucco plaster with a particle size of ⁇ 300 ⁇ m, 0.02 to 0.5% Starch ether, 0.2 to 1% methyl cellulose, 0.5 to 3% Polyvinyl alcohol, 0.001 to 0.1% of a boric acid or an alkali metal or alkaline earth metal salt Contains boric acid.
  • a gypsum fibreboard system is used for the first time provided, which on the one hand the easy installation the plates butt and on the other hand the desired one allows a firm bond between such plates.
  • the Gypsum fiberboard joints according to the invention easier to fill than with conventional ones Gypsum fibreboard and have the required Joint strength.
  • 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. So that between the heavier gypsum fiber boards form a firm bond, which has therefore been assumed so far that this only due to the classic laying with a sufficiently large size Joint space and a backfill with a corresponding large amount of a joint filler can be achieved.
  • the rounded edges of the Plasterboard are covered with a layer of cardboard, so that thereby stabilizing the edge on the other hand, the joint filler is used on it is coordinated to adhere well to the paper surface.
  • the chamfer of the gypsum fibreboard according to the invention must be designed such that the web height of the Gypsum fiber board edge 5 to 50% of the board thickness, but at least 1 mm.
  • the web height is lower as 5% of the panel thickness or as 1 mm, the edge when chamfering, transporting or installing the gypsum fibreboard abort. If, on the other hand, the web is significantly higher than 50% the plate thickness, the joint space is too small and the Filling the joint usable amount of joint filler it is not enough to achieve the desired joint strength guarantee.
  • 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 plasterboard 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 of Paris mixes the joint filler in a lot 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 starches. These thickeners are in one Amount from 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.
  • Polyvinyl alcohol and boric acid or an alkali / alkaline earth salt a boric acid 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.
  • the viscosity and viscosity of the joint filler can be affected by Addition of fibers, in particular cellulose fibers, further being controlled.
  • Cellulose fibers can, for example the dry joint filler mixture in quantities up to 1 % By weight are added.
  • the joint filler according to the invention is dimensionally stable and elastic, so that neither crack nor bulge are expected. Those in the network of comparatively heavy gypsum fiber boards due to external loads Stresses that arise are caused by the joint added without this adversely affecting the joint affects.
  • 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 straight 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.
