FRONTAL BUTT CONNECTION BETWEEN TWO ROOF SLAB ELEMENTS OF A FLAT ROOF AND CORRESPONDING ROOF SLAB ELEMENT

摘要

The invention relates to a frontal butt connection between two roof slab elements of a flat roof and to a corresponding roof slab element (1) which comprises undercuts, grooves or pockets (8, 9) integrated into its profile walls (6, 7). In this area the pockets of at least one roof slab element are substantially recessed in the form of slots (11) or a jog (15), and the apex of the slab can be removed. The slabs can be nested into one another or stacked without the pockets or grooves mutually impeding one another. Especially when the slots or the jog is configured in such a way that they almost halve the pockets next to the upper chord, the remaining pockets enclose the pockets of the subjacent slab. The top slab, in the slot area, is elastic to such an extent that it almost engages into the upper chord of the lower slab. The roof slab elements can be fastened, for example, in the area of the overlapping upper chords or with their slab surfaces resting on the purlin either with one another and/or on the purlin. The invention allows a gap-free butt connection of the roof slab elements despite their projecting pockets.
