Definitions

  • the invention relates to a terrace covering according to the preamble of the first claim.
  • the invention is also based on a method for fixing boards on a substructure for a terrace covering according to the preamble of the independent method claim.
  • Terrace coverings as compounds of wood parts with each other and on the ground, in particular of planks or planks of balcony and Outdoor patio covers are known.
  • the wood parts are screwed together, and this can be done from above or for aesthetic reasons, from below through the substructure.
  • the screwing from above is very easy to implement, the screw from the bottom relatively complicated.
  • mounting brackets for connecting wood parts are described, as they are used in particular for attaching planks of balcony and patio covers outdoors.
  • the mounting bracket is essentially formed as a composite of two L-profiles double angle.
  • these brackets are very expensive and not easy to use.
  • the invention is based on the object, in a terrace covering and a method for fixing boards on a substructure for a terrace covering of the type mentioned, to provide a simple and secure fastening system, which avoids the disadvantages of the prior art.
  • the core of the invention is therefore that the planks are connected by means of an elastic adhesive to the substructure.
  • the advantages of the invention can be seen in the fact that, as a result of the elastic bonding, it is possible to prevent bumps as known from the prior art.
  • the assembly is also greatly simplified and meets the highest aesthetic standards.
  • very good strengths and a cohesive fracture pattern result.
  • an elastic polyurethane adhesive, polyurethane hybrid adhesive and / or MS adhesive is used as the adhesive. Furthermore, it is expedient to use spacers for the assembly, which guarantee a certain adhesive thickness in order to ensure a good bond.
  • ⁇ coverings For the production of terrace coverings, various types of wood such as larch, pine, oak, spruce, Douglas fir, Bankirai, etc. can be used. According to the present invention, these wood coverings, also called planks, are glued to the substructure, which usually consists of the same type of wood, but may also consist of another type of wood or another material. In Fig. 1 and 2, such an adhesive bond is shown by way of example. On the substructure 1 of pale-shaped woods, the boards 2 are glued. Substructures and planks can be made of any type of wood or other materials such as plastics, metal, concrete, stone, granite, etc. On the substructure, a spacer 3 is placed, which is also referred to as an assembly line.
  • a spacer 3 On the substructure, a spacer 3 is placed, which is also referred to as an assembly line.
  • adhesive beads 4 are applied to the substructure and then placed the planks.
  • the adhesive bead can be applied and then only the assembly line.
  • the spacer is applied centrally on the lath-shaped substructure wood, and applied an adhesive bead on both sides of the tape. Due to the thickness of the spacer, the thickness of the bond can be adjusted.
  • a SikaTack® panel assembly tape is preferably used, which results in an adhesive thickness of 3mm.
  • Advantageous adhesive thicknesses are in a range of 1 to 5mm, especially in a range of 2 to 4mm.
  • the bond should have a certain thickness in order to achieve a sufficiently strong bond.
  • a primer can be applied to the areas to be bonded, which improves the adhesion of the adhesive on the wood.
  • adhesive for the bonding of the terrace coverings preferably elastic adhesives such as one- or two-component polyurethane adhesives, polyurethane hybrid adhesives and MS adhesives are used.
  • An MS polymer is a polyether having at least two alkoxysilane groups.
  • Such MS polymers are well known to the person skilled in the art and are described, for example, in US Pat. No. 6,207,766 in column 4 lines 27 to 54 and in US Pat. No. 3,971,751.
  • R1 and R2 hereby independently of one another represent a C1-C8-alkyl radical, in particular methyl or ethyl, and a represents the value 0 or 1, in particular the value 0.
  • a catalyst is used, which is usually a platinum catalyst.
  • Such MS polymers have, inter alia, the advantage that they can be prepared without the use of isocyanates and, secondly, that these compounds have a particularly low viscosity, so that they are very suitable for use in one-component moisture-curing compositions.
  • alkoxysilane-terminated polyurethane prepolymers can be used as polyurethane hybrid adhesives. These alkoxysilanterminerten polyurethane prepolymers can either from the reaction product of an OH-terminated prepolymer prepared from polyols and polyisocyanates in the stoichiometric excess of the polyisocyanate, and a Isocyanate group-bearing alkoxysilane, or from the reaction product of an NCO-terminated prepolymer prepared from polyols and polyisocyanates in stoichiometric excess of the polyisocyanate, and an NCO-reactive groups bearing alkoxysilane, such as aminoalkoxysilanes or mercaptoalkoxysilanes be.
  • Another possibility is the reaction of a polyol with an isocyanate group-bearing alkoxysilane.
  • Another possibility is the addition reaction of an aminoalkoxysilanes or mercaptoalkoxysilanes to the double bonds of double bond-terminated polyols as used in the preparation of the MS polymers for hydrosilylation
  • one-component polyurethane adhesives contain polyurethane prepolymers which have isocyanate groups or alkoxysilane groups.
  • the isocyanate group-containing prepolymers are typically prepared from at least one polyisocyanate and at least one polyol.
  • the reaction can be carried out by reacting the polyol and the polyisocyanate with customary processes, for example at from 50 ° C. to 100 ° C., optionally with concomitant use of suitable catalysts, the polyisocyanate being metered in such a way that its isocyanate groups in the Ratio to the hydroxyl groups of the polyol in stoichiometric excess are present.
  • the excess of polyisocyanate is chosen so that in the resulting polyurethane prepolymer after the reaction of all hydroxyl groups of the polyol, for example, a content of free isocyanate groups of 0.1 to 15% by weight, preferably 0.5 to 5% by weight based on the total polyurethane prepolymer remains.
  • the polyurethane prepolymer can be made with the concomitant use of plasticizers, wherein the plasticizers used contain no isocyanate-reactive groups.
  • Alkoxysilane-containing prepolymers are typically prepared by reacting the isocyanate group-containing prepolymers with an amino or mercaptosilane, in particular amino or mercaptotrialkoxysilane obtained, so that the resulting prepolymers are substantially free of isocyanate groups.
  • these one-component polyurethane adhesives typically also contain fillers, in particular carbon black and / or chalk, plasticizers and catalysts, and usually have a paste-like consistency.
  • the one-component polyurethane adhesives crosslink by contact with water, usually present in the form of atmospheric moisture, to a polymeric material.
  • SikaBond® T1 and SikaBond® T2 were used as adhesive.
  • Sika®Primer 2 and 3 is a solvent-containing polyisocyanate, with the solvents and polyisocyanates varying.
  • SikaTack®-Panel Primer is a solvent-based, epoxy resin.
  • Plank larch size 28x130mm was glued to 28x75mm construction wood.
  • the finished grate had the size of approx. 550x550 mm.
  • the commercial larch planks were selected due to the high resin content and the wood, which tends to warp.
  • planks were glued with and without primer and planks without gluing screwed. For the selection of wood, especially clean, planed, straight wood was chosen to ensure comparability.
  • the present bonding results in a significantly better picture than with the conventional screw.
  • Systems with primer treatment are advantageous over a bond without primer treatment. Bonding with SikaTack®-Panel Primer and SikaBond® T2, in particular, was particularly advantageous. with a primer of solvent-based, pigmented epoxy resin and a one-component polyurethane adhesive.
