Abstract: Panel-shaped components are used for interior construction, e.g., for covering walls, ceilings and/or fabricating lightweight walls. Connecting elements are used during the assembly of such wall components. A connecting element is suitable for connecting several such wall components with each other, thereby greatly simplifying the assembly of wall components above all with respect to handling, and increasing the stability of such a wall. For this reason, such a connecting element has two U-shaped profiles offset to each other, which can accommodate at least two wall components, preferably plasterboards, whose narrow sides abut against each other. The non-positive connection between the connecting element and a wall component is established according to the invention using pop rivets or the known drywall screws.

Abstract: The present invention relates generally to the field of general building construction, comprised predominantly of panel-shaped supporting and non-supporting elements. These panel-shaped components are used for interior construction, e.g., for covering walls, ceilings and/or fabricating lightweight walls. Connecting elements are used during the assembly of such wall components. The present inventive connecting element is suitable for connecting several such wall components with each other, thereby greatly simplifying the assembly of wall components above all with respect to handling, and increasing the stability of such a wall. For this reason, the inventive connecting element has two U-shaped profiles offset to each other, which can accommodate at least two wall components, preferably plasterboards, whose narrow sides abut against each other. The non-positive connection between the connecting element and a wall component is established according to the invention using pop rivets or the known drywall screws.

Abstract: The invention relates to a polyol mixture which comprises as components a1) at least one fat-based polyol, a2) at least one polyetherol having a number average molecular weight of from 500 to 2000 g/mol and a3) if appropriate one or more crosslinkers having a number average molecular weight of from 90 to 400 g/mol, where x) the number average molecular weight of component a1) differs by not more than 400 g/mol from the number average molecular weight of component a2) and xi) components a1) and a2) do not differ from one another in OH functionality by more than 0.5. These polyol mixtures can be employed to produce polyurethane-based embedding compositions. The invention additionally relates to embedding compositions based on the polyol mixtures (A) described at the outset and at least one modified isocyanate (B) and to the use of the embedding compositions as potting material. The invention further relates to a process for producing the embedding compositions as described at the outset.

Abstract: The invention relates to a composite material having two or more superimposed wood layers. Said layers are joined together by means of a one component polyurethane adhesive containing a prepolymer having free NCO groups and a wood having a volume fraction of libriform fibres in the region of between 50-70% is used.

Abstract: The invention relates to the use of a composite material having two or more superimposed layers of wood as a support element in structural engineering, nautical, vehicle and aircraft constructions, energy production systems, mining or in the production of furniture. The wood layers are joined together by means of a one component polyurethane adhesive containing a prepolymer with free NCO groups and the wood has a structure having a volume fraction of libriform fibers of between 50%-70%.
