Definitions

  • the invention relates to a formwork element with a layer structure.
  • a layer structure is understood to mean an element which has several layers.
  • shuttering elements known, for example DE 38 15 870 C1 in which a steel mesh mat is covered by a foil.
  • the film is a stable shrink film, for example made of polyethylene, with which the latticework of Baustahlmatte is shrunk, so that the grid openings are each closed by two layers of film and thus one obtains a flat, concrete impermeable formwork element.
  • the object of the invention is to provide a novel, lightweight formwork element.
  • the layer structure comprises two plates, wherein the plates each have at least one layer having a plurality of layers, and wherein a wavy layer of a layer of a plate and a wavy layer of a layer of other plate are wavy in different directions.
  • a wave of a wave-like layer of a layer of the one plate extends transversely to a shaft of a wave-like layer of a layer of the other plate.
  • the formwork element according to the invention is used for permanent formwork, for example foundation formworks, then it may be advantageous if the material of the formwork element rots gradually after moisture absorption.
  • the layer structure has a structure arranged between the plates, preferably a honeycomb structure, wherein walls which form the structure extend transversely to the plates.
  • a honeycomb structure is understood to mean an element which has a large number of honeycombs.
  • the walls of the structure are glued to the plates. Due to the stabilizing interaction of the structure and the plates, a high stability of the formwork element can be achieved at the same time as low weight using suitable, thin, lightweight materials. It also comes into consideration materials for the plates and the structure that could not previously be used for lost formwork. In particular, low density materials such as paper or paperboard can be used.
  • said walls are made of paper or cardboard.
  • said walls are formed by strips each defining a plurality of honeycombs together with adjacent strips.
  • the strips are kinked or bent, such as zigzag or wavy. They are preferably glued together.
  • the plates each have at least one layer with a plurality of layers, of which at least one layer is wavy.
  • the layers of paper or cardboard Preferably, the layers of paper or cardboard.
  • a wave-shaped layer results in high material stability at low material density.
  • the plates each have at least two such layers whose undulating layers are corrugated in different directions.
  • the wave of a wave-like layer of a layer can extend transversely to the wave of a wave-like layer of another, in particular adjacent layer.
  • the plates each have three such layers, each with a wave-like layer.
  • the plates can also be constructed differently, and the described characteristics of the plates can be present in only one of the two plates.
  • the layer structure is covered by a film.
  • the layer structure is protected against wetting.
  • the film is perforated. Due to the extent of the perforation, the rate of water absorption of the material of the plates can be selectively controlled from the moisture released when setting the concrete.
  • an insulating layer is arranged on at least one side of the layer structure. If the formwork element according to the invention for lost formwork, such as foundation formwork is used, so can be achieved with the help of the insulating layer in a simple way, a heat and / or sound insulation.
  • the insulating layer may consist of conventional insulating materials, such as foam polystyrene, rock wool or the like and may be formed for example by one or more insulating panels.
  • the insulating layer is within the film and thus protected against moisture acting from the outside, also other insulating materials come into consideration, especially open or closed-cell materials or fiber materials with low density, which have a particularly low thermal conductivity.
  • the insulating layer may consist of foamed plastic material.
  • the insulating layer can be fixed by the shrink film in the desired position on the layer structure, so that the formwork element and the formwork formed therefrom can be produced in a particularly simple manner.
  • the honeycomb structure is interrupted by at least one cavity for receiving a peg.
  • FIG. 1 a plate-shaped shuttering element is shown with a layer structure 12, and in the FIGS. 2 to 4 a similar plate-shaped shuttering element is shown, in which the layer structure 12 is additionally covered with a shrink film 13.
  • the formwork elements of the Figures 1 and 2 constructed identically and will therefore be described together below. With the exception of the film 13 corresponds to in the Figures 3 and 4 structure shown also after the formwork element FIG. 1 ,
  • the layer structure 12 consists of two plates 14, 16 and a honeycomb structure 18 arranged between these plates 14, 16.
  • the plates 14 and 16 each consist of a three-layered cardboard, each of the three layers containing a corrugated layer 20 and 22, respectively.
  • the shaft of the shaft layer 22 of a middle layer extends transversely to the shaft of the wave layers 20 of the outer layers.
  • the wave layers 20, 22 each extend between smooth layers 24.
  • Walls 26 of the honeycomb structure 18 are formed by strips of paper which, as in FIG. 4 can be seen, wavy or kinked run and each together with adjacent strips to limit the honeycomb of the honeycomb structure. The edges of the walls 26 are glued to the respective adjacent plates 14, 16.
  • a cavity 28 is shown which interrupts the honeycomb structure 18 and extends in a vertical direction through the formwork element to receive a peg for fixing the formwork element.
  • Such cavities 28 are formed, for example, at regular intervals in the formwork element.
  • the film 13 may be perforated so that the moisture released upon setting of the concrete can pass through the perforated film 13 and be absorbed by the plates 14 and 16 and the honeycomb structure 18, respectively.
  • the film 13 can be pierced on the inside of the formwork element at different locations.
  • FIG. 5 shows a configuration in addition to one side of the formwork element, for. B. between the plate 14 and the film 13, an insulating layer in the form of an insulating plate 30 is provided.
  • the film is preferably not perforated.
  • the insulating panel 30 may have any desired thickness for the purpose of thermal insulation, for example, between 30 and 120 mm, and may be made of any insulating materials such as foamed polystyrene, rock wool and the like. Instead of a rigid insulation board, a flexible insulating layer of rock wool or other suitable material can be used. Likewise, the insulating layer can also be formed from a loose bed of granules or the like, which is held by the shrink film 13 in its shape.
  • the insulating layer may also have moisture-storing properties, or it may be provided in addition to the thermal barrier coating, a moisture-absorbing layer. In this case, the film 13 may be perforated again.
  • the film 13 may also be dispensed with, and the insulating layer may be glued to the plate 14, for example.
