Patent ID: 8402715

Claim:
A structural member for construction, said structural member, comprising: (a) a two-dimensional extent, and (b) a plurality of adjacent arranged hollow shaped elements extending across the two-dimensional extent of the structural member, said hollow shaped elements being made from a fibrous textile material and being impregnated with a binder made of a thermosetting reactive resin, wherein: (i) the hollow shaped elements each have a shape of a truncated cone with a continuous peripheral side wall and a cover surface and the adjacent hollow shaped elements are connected to each other at their side walls, (ii) two structural spacing parts extend in parallel to the two-dimensional extent of the structural member and form arrangements of the hollow shaped elements, (iii) each of the structural spacing parts has a base layer on which the hollow shaped elements belonging to this structural spacing part are arranged at mutual intervals, (iv) the structural spacing parts are arranged in opposite orientation so that the hollow shaped elements of a first structural spacing part protrude into spaces between the hollow shaped elements of a second structural spacing part and each of the hollow shaped elements touching each other with their side walls belongs to another one of the structural spacing parts, (v) the interlocking structural spacing parts are formed so that they are complementary relative to each other, wherein the spaces between the hollow shaped elements of the first structural spacing part are adapted to sizes of the hollow shaped elements forming the elevations of the second structural spacing part and vice versa and cover surfaces of the hollow shaped elements of the first structural spacing part touch base areas of the base layer in spaces between the hollow shaped elements of the second structural spacing part and vice versa, and (vi) the hollow shaped elements are joined to each other positively by force-fit along the side walls being face to face in contact with each other and by said reactive resin and the hollow shaped elements are deformed by mutual local pressure of adjacent hollow shaped elements.
