The invention relates to a construction panel consisting of superimposed elements »

An object of the invention is to make one in a simpler and more economical To create way manufacturable panel, which has particular advantages in terms of use in construction. As is desirable in building construction or house construction, the Panel in particular have advantages relating to the comfort of the residents and at the same time be protected against fire. According to the invention, this object is achieved in that the construction panel consisting of superimposed elements contains a soul made up of non-combustible cell walls divided foam is formed and the on both Pages - apart from an outer cladding - also with a sequence of foils and / or layers and / or plates which make the board resistant to impacts and which connect the layers and are self-extinguishing Have properties.

In a preferred embodiment, the foils and / or layers and / or plates are with one another and with the core made of foam connected with the help of a self-extinguishing resin. Preferably hydrous resin or "polyester

Resin used for this.

The following description relates to an embodiment of a panel constructed in accordance with the invention. she takes Refer to the attached drawing in which

Fig. 1 is a schematic partial view of a core of a panel designed according to the invention, partly broken open, and

Figure 2 shows a section through a panel constructed in accordance with the invention.

The construction panel according to the invention contains a core 10 from in material divided into incombustible cells, which can consist, for example, of a mixture of foamed and hardened resin. According to a preferred embodiment, the core 10 is made of a network 11 with hexagonal cells 12 and rigid cell walls 13 formed, for example from I. metal foil, with Resin-soaked cellulose material or the like can consist. The individual cells are filled with foam 14. The core 10 thus not only has qualities in terms of heat and noise insulation, but also an increased resistance in particular against a pressure acting on the surfaces 15 and 16.

Plates 17 and 18 are arranged on both sides of the core 10, which essentially serve to increase the resistance of the board to impacts. These plates 17 and 18 can consist of pressed wood chips. To connect the plates 17 and 18 to the core 10 is a relatively thin intermediate layer 19 or 20 is provided, which consists, for example, of a glass film or a layer preferably composed of fibers. For this purpose, e.g. glass, steel or asbestos fibers soaked with synthetic and self-extinguishing resins can be used.

On the outer sides of the plates 17 and 18 are located thin and waterproof shielding films 21 and 22, preferably of an aluminum layer between two foils made of kraft paper or a waterproof one against high temperatures and mechanical stress-resistant paper can be formed «The foils 21 and 22 close the The board is steam and waterproof and also serves as fire protection

The shielding films 21 and 22 are each supported by a reinforcing layer 23 or 24 covered from fibers, including preferential | wisely soaked with self-extinguishing resin, glass, steel or Asbestos fibers are used. The outer panels 25 and 26 of the panel are placed on these reinforcement layers, the de * may vary depending on the purpose: color, wood paneling or other paneling for reasons decoration or mechanical or chemical durability. The cladding can also be made from consist of a self-extinguishing "gel-coat" (gel layer).

Preferably, the reinforcement layer 24 is extended beyond one edge of the panel (see reference numeral 27) by the to protect narrow sides of the various panels and layers. The shielding layer serves the same purpose. 22 g and tie layer 20 elongated and folded back

(See reference numerals 28 and 29 or 30 and 3Ό and the free Ends 29 and 31 lie between the shielding film 21 as well the plate 17 on the one hand and between the plate 17 and the Link layer 19 on the other hand.

The various layers are connected to one another; through a liquid applicable resin, which can be changed by adding solidified by a suitable agent after use. The panel is expediently manufactured in one

Shape. After the bottom of the mold has been treated with an agent that makes it easier to remove the panel from the mold, a layer is first applied manually or by spraying to form the outer cladding the board forms. The reinforcement layer 24, the shielding layer 22, the plate 18 and the connecting layer 20 are laid. After that, the soul turns 10 - depending on your choice of the starting material in one or more layers - laid on top and then the remaining layers follow one after the other, whereby also the extensions serving to protect the narrow sides of the layers are folded and placed between the corresponding ones Layers are inserted. The last layer to be applied, which forms the outer cladding, can also be on the lid attached to the form. The connecting means used is preferably a water-containing resin, which is solidified by Adding cold water, possibly under pressure. Self-extinguishing polyester resin can also be used will. After opening the mold, the finished panel can be removed immediately.

The board created in this way is fireproof and therefore self-extinguishing resin is used.
