| 摘要 |
The present invention relates to a device on building elements which, arranged next to one another, form slabs and/or walls, the building elements (1) holding one another and permitting limited mobility relative to one another and each building element (1) having both a laterally projecting longitudinal tenon (6) and a recess (8) arranged on an opposite side and intended for receiving the longitudinal tenon (6) of an adjacent building element (1), and also having at least one through-channel (14) which extends between mutually opposite end faces (4, 9) of the building element (1), and also, in at least one of the end faces, having slots (10, 11) in order to guide liquids penetrating downwards between the building elements (1) to the channel (14). To enable effective capture of the liquid which has hitherto largely run off between the building elements without being received by the channels, the present invention is characterised in that the building element (1) has at least one longitudinal groove (15) which is open towards the top in the upper side (13) of the longitudinal tenon (6) of the building element (1) and which opens out into the one slot (10) of one end face (9). <IMAGE> |
