Abstract

1. Tornillo de obra rápido autocortante, para la fijación de placas de fibras a una subestructura metálica, con un vástago de tornillo que lleva al menos un filete de rosca y que hace transición a una punta taladradora cónica provista de al menos una entalladura de corte, y con dos alas de corte dispuestas cerca del extremo del vástago, las cuales se rompen al tropezar con la subestructura metálica y al menos una de las cuales corta hasta el diámetro exterior de la rosca, caracterizado porque las dos alas de corte están axialmente desplazadas una respecto de otra, porque el ala de corte delantera está asentada sobre la superficie envolvente de la punta taladradora cónica y corta hasta el diámetro del núcleo del tornillo, y porque la punta taladradora representa un ángulo de cono de menos de 45 grados. 2. Tornillo de obra según la reivindicación 1, caracterizado porque otra ala de corte central está dispuesta sobre la superficie envolvente de la punta taladradora cónica en posición axial entre el ala de corte delantera y el ala de corte trasera asentada sobre el vástago del tornillo. 3. Tornillo de obra según la reivindicación 2, caracterizado porque las tres alas de corte están distribuidas uniformemente por la periferia. 4. Tornillo de obra según la reivindicación 1, caracterizado porque en la punta taladradora cónica están previstas dos entalladuras de corte enfrentadas entre sí. 5. Tornillo de obra según la reivindicación 1, caracterizado porque en la punta taladradora cónica están previstas tres entalladuras de corte distribuidas por la periferia. 6. Tornillo de obra rápido autocortante.
