Definitions

  • the invention relates to a formwork bracket for ceilings, which has a formwork wall made of a multilayer lightweight building board with an insulation plate, which lies between the outer and the inner formwork plate, wherein a support plate is arranged at right angles to the formwork wall, with at least the lower end faces of the formwork panels by an adhesive layer connected is.
  • formwork angles for ceilings are already known.
  • the formwork angles mentioned there consist of a multilayer lightweight building board, with between the outer and the inner layer is the insulation plate.
  • the support part is also a lightweight board that is connected to the lower end of the formwork wall by an adhesive layer.
  • the formwork brackets known to date have high thermal insulation and have no annoying rounded part on the inside.
  • the high insulation is achieved through the multilayer lightweight construction board with the insulation board in between.
  • a rounding part is no longer necessary, as with previous formwork angles.
  • the invention described by the laid-open publication has the advantage over the previous formwork angles that the multilayer lightweight building board and the support part formed from a lightweight building board are very light in weight. That means they are easy to handle. For example, this allows longer lengths of a part.
  • the present invention is therefore based on the object of providing a device of the type mentioned at the outset which makes it possible to achieve a fast setting time without having to accept losses in terms of a firm and resistant connection between the multilayer lightweight building board and the support part.
  • this object is achieved in that an intermediate layer over the length of the formwork angle is applied from at least two different adhesives, at least one adhesive being a fast-curing adhesive and the other a slow-curing adhesive.
  • the decisive advantage of this solution is that the positive properties of the two different adhesives are bonded together without their negative properties having an effect. Since the quick-setting adhesive has already hardened within a short period of time, there is already a short connection between the multilayer lightweight building board and the support part. The two parts therefore only have to be pressed together within the setting time of the fast-curing adhesive. Then the multilayer lightweight building board and the support part are pressed together by the already hardened fast-curing adhesive, thus enabling the slow-curing adhesive to exert the necessary contact pressure.
  • the resulting formwork angle can be stored at any location.
  • the pressing device required to compress the formwork angles can now be immediately occupied by a new formwork angle to be pressed.
  • At least two adhesives are arranged or applied in a grid.
  • the advantage of the quick-curing polyurethane adhesive is that it has a very short setting time of only about 15 minutes.
  • Polyurethane adhesives are often used as adhesives or sealants. So this adhesive is a conventional, commercially available adhesive.
  • the slow-curing adhesive is a two-component adhesive with hardener.
  • a two-component adhesive is generally a setting adhesive in which, for example, monomers, on the one hand, and hardener, on the other hand, are present as separate components which are only mixed together by the user shortly before use.
  • the two-component adhesive with hardener can be an epoxy resin adhesive.
  • the epoxy resin adhesive combines the aforementioned positive properties of a two-component adhesive in an optimal way.
  • a two-component adhesive often consists of epoxy and hardeners of amines.
  • An epoxy resin adhesive is a common reaction adhesive and is therefore commercially available, easy and inexpensive to obtain.
  • the fast-curing adhesive and the slow-curing adhesive are arranged alternately in a grid pattern over the length of the formwork angle, the size of the individual grid being 25-50 cm.
  • fast-curing adhesive and the slow-curing adhesive are arranged in a grid pattern over the entire length of the formwork angle, the size of the individual grid between 30 - 40 cm.
  • a particularly advantageous solution consists in that the adhesive (S) applied to the end regions of the two formwork panels is in each case a fast-curing adhesive (S).
  • the arrangement of the quick-curing adhesive in the area of the end faces enables a secure quick connection after assembly without the risk of tears or tears on the end faces during transport, e.g. occur for intermediate storage to harden the slow-curing adhesive.
  • the multilayer lightweight building board consists of wood cement and the support plate consists of a cement-bonded chipboard tested for compressive strength (at least 3 N / mm2).
  • the formwork bracket for ceilings has a vertical formwork wall 1, which consists of a multilayer lightweight building board with an outer layer 2, an inner layer 3 and an insulation plate 4 in between.
  • the width of the outer and inner layers will generally be between 1 and 4 cm, while the thickness of the insulation plate will be between 3 and 5 cm. Of course, other values are also possible here.
  • a support part 5 is connected at right angles to the formwork wall 1.
  • the support part 5 consists of a wood-cement board, the thickness of the board being 8 mm. Of course, other dimensions are also possible here.
  • the support part 5 is fastened to the uppermost stone layer 8 either by pins, nails 7 or the like.
  • the support part can also be attached to the uppermost stone layer 8 by means of a mortar or adhesive connection.
  • the width of the support part 5 can also be chosen freely.
  • this adhesive layer consists of two different adhesive layers (S, L) arranged in a grid.
  • two different adhesives are arranged at regular intervals at the lower end of the formwork wall 1 on the outer layer 2 and the inner layer 3.
  • One adhesive is a fast-curing polyurethane adhesive (S) and the other is a slow-curing two-component adhesive (L) with hardener, which is designed here as an epoxy resin adhesive.
  • the quick-curing adhesive (S) has a setting time of about 15 minutes.
  • the slow-curing epoxy resin adhesive (L) has a setting time of around 24 hours. This means that after about 15 minutes the formwork angle can be removed from the necessary pressing device.
  • the adhesives applied in a grid are arranged at regular intervals.
  • the size of the individual grid is between 30 - 40 cm.
  • the adhesive applied to the two end regions of the two formwork panels is in each case a fast-curing adhesive.
  • the multilayer lightweight building board with its two layers 2 and 3 and the insulation plate 4 in between can be constructed from different materials.
  • the insulation plate is e.g. Styrofoam, Styrodur or any other insulation material with a suitable stiffness is suitable.
  • the outer layer 2 and the inner layer 3 can also consist of a wide variety of materials, generally using the lightest and most stable materials possible and these should preferably also be heat-insulating to a certain extent.
  • the multilayer lightweight building board consists of materials by means of which it can be connected well and firmly to the support part 5 by means of the adhesives according to the invention.
  • a wide variety of materials are also conceivable for the support part 5, provided that there is a corresponding compatibility or connectivity with the adhesives according to the invention.
