DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a panel-shaped building element.
DESCRIPTION OF THE INVENTION
A composite element is known from DE 1 484 322 A1 which is composed of a folded-plate structure and heat insulation located on either side in the form of a plastic foam foamed into the corrugations between the legs of the folded-plate structure. The two large surfaces of the known building element are covered with a lining of cover foils.
SUMMARY OF THE INVENTION
The object of the invention is to make available, proceeding from DE 1 484 322 A1, a simplified structure of a building element, which can be used as a ceiling, wall, floor or roof element.
It is advantageous in the building element as claimed in the invention that by the corresponding selection of the shape of the folded-plate structure and optionally by the attachment of planks on one or both sides it can be matched easily and without abandoning the principle as claimed in the invention to the respective application.
The plastic foams which can be used within the framework of the invention are not limited to polyurethane or polystyrene plastics, but other foam plastics can be used to advantage, for example, those based on vegetable (rapeseed) oil.
It is especially advantageous that the folded-plate structure provided in the building component as claimed in the invention is provided with openings (holes of any shape), since then the plastic foam provided on either side of the folded-plate structure is integral over its parts which extend through the openings so that the support function of the plastic foam is increased. For openings in the folded-plate structure there is also the advantage that the plastic to be foamed in the production of the building element as claimed in the invention need be located only on one side of the folded-plate structure, and still completely fills the other side of the folded-plate structure under the action of the foaming pressure.
Other details and advantages of the panel-shaped building element as claimed in the invention follow from the description below.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 1 through 4 show different embodiments of the building panel in cross section.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the embodiment of panel-shaped building element 1 as claimed in the invention (building panel), folded-plate structure 2 of wood fiber or particle material are provided with corrugations 6 and with planks 4 located on both sides. The cavities between planks 4 and branches 8 of folded-plate structure 2 which proceed from corrugations 6 are completely filled with plastic foam.
In this case plastic foam 7 which for example is a polyurethane or a polystyrene foam, is foamed into the cavities so that it not only fills the cavities, but also acts as an adhesive which fixes planks 4 to folded-plate structure 2 so that uniform, stable building panel 1 results.
Openings (holes) can be provided in branches 8 of folded-plate structure 2 so that plastic foam 7 can extend in one piece through folded-plate structure 2 and thus the strength of building panel 1 is increased.
In the embodiment shown in FIG. 1 corrugations 6 of folded-plate structure 2 do not extend as far as inner surfaces 5 of planks 4.
FIG. 2 shows an embodiment in which building panel 1 is made without planks 4. This embodiment is produced in a mold and has smooth outer surfaces 9 which are provided directly with a surface treatment, for example, they can be papered, painted and/or plastered. Outer surfaces 9 can however also be made with a structure matched to the surface treatment (grooved, burled, etc.).
The embodiment of building panel 1 which is shown in FIG. 3 has a construction similar to FIGS. 1 and 2, here branches 8 of folded-plate structure 2 being made from wooden boards which are joined to one another in the area of corrugations 6.
In the embodiment of building element 1 (building panel) shown in FIG. 4, folded-plate structure 2 is a corrugated sheet (for example, raw, galvanized or otherwise surface-treated ste
