Definitions

  • a corresponding con- sideration is that a head of a screw, regardless of its profile, will be prevented from producing an outwardly-directed compression when it is configured with skirt part extending rearwards from the circumference of the screw head, which when the screw is screwed in will form a mechanical shiel- ding-off of that material area in which a compression of the material can possibly arise with the final screwing-in.
  • a screw according to the invention will thus be characterised by an appearance which is radically different from the above-mentioned, hitherto-preferred screw, i.e. by being provided with a decidedly " thick" outer edge on the screw head. This will appear quite illogical until it is seen that the back of the screw head within the outer edge is " hollow” , so that a compression of the material can arise without this in any way being able to spread to the area outside the head of the screw.
  • fig. 1 is sectional view of a screw according to the invention, shown during the initial screwing-in of the screw head in a plaster board surface, while fig. 2 is a corresponding view of an almost complete screwing-in, and fig. 3 is a corresponding view of the finally completed screwing-in.
  • the shown screw has a screw shank 2 with a thread 4, above which the neck 6 of the screw is configured with the same thickness as the core of the thread, i.e. preferably not with a greater thickness than this, and a screw head 8 which immediately appears as a " block head" with cylindrical outer side 10.
  • the screw head has a slot 12 of any usable type .
  • the underside of the screw head has an annular recess 14 around the neck 6 of the screw, said recess being of curved cross-section with gradual transition to the screw neck and with a short, rounded-off transition 16 to the outer side 10 of the screw head.
  • the screw 1 is shown screwed so far into a plaster board 20 that it has started to penetrate an under layer of wood W.
  • the head 8 will gradually penetrate deeper into the plaster, cf. fig. 3, whereby the plaster will be compressed locally.
  • This compression will immediately manifest itself most strongly under the downwards-extending edge area of the screw head, but this most strongly compressed material will naturally seek inwards and upwards under the " dome" which is formed by the recess 14, as shown by the arrow in fig. 3, whereby the differentiated compression in under the screw head will be substantial- ly equalised to an acceptable level despite the large peripheral thickness of the screw head.
  • Screw in particular for the fastening of cladding plates of the plaster board type, with a screw shank and a screw head with a groove or the like in the top, c h a r a c t e r i s e d in that the screw head is configured with a substantially flat top and with a skirt part extending downwards from the outer edge of said head top, and which within the underside of the screw head forms an annular cavity around the screw shank.
  • Screw according to claim 1 c h a r a c t e r i s e d in that said cavity meets the under edge of the skirt part in a wholly or semi-sharp manner.

Abstract

L'invention concerne une vis spéciale destinée à la fixation de plaques de plâtre. Cette vis comprend une tête de vis en forme de bloc dont le côté inférieur est pourvu d'une cavité annulaire entourant la tige de la vis. Lorsqu'on utilise cette vis, le volume de plâtre déplacé par la vis est comprimé à l'intérieur de cette cavité. Ainsi, du fait que le côté inférieur de la tête de vis n'exerce pas de pression radiale poussant ce volume vers l'extérieur, le gonflement extérieur du plâtre, qui devrait normalement apparaître autour de la tête de vis lorsque celle-ci est complètement vissée, peut être entièrement évité. L'utilisation de cette vis permet donc de réduire au minimum, voire de supprimer, l'opération de ponçage qui serait alors nécessaire.
