Abstract
Przedmiotem zgłoszenia jest wkręt (1) śrubowy ze zoptymalizowanym gwintem symetrycznym do montażu termoizolacji ma trzpieniowy rdzeń (2) wyposażony w gwint (3) i zakończony wierzchołkiem (4) zwężającym się w kierunku wkręcania pod kątem wierzchołkowym (α), który zawiera się w przedziale od 40° do 50°, przy czym symetrycznie trójkątny w przekroju promieniowym zarys gwintu (3) jest obwodowo spiralny o skoku (S), odpowiadającym od 0,35 do 0,55 średnicy (d<sub>r</sub>) rdzenia (2) i ma kąt wierzchołkowy (φ), który wynosi od 45° do 55°. Zewnętrzny promień (R) wieńca gwintu (3) wynosi 0,1 mm, natomiast średnica (d<sub>r</sub>) rdzenia (2) jest mniejsza od średnicy nominalnej (d<sub>n</sub>) wkręta (1) w proporcji od 0,7 do 0,8.The subject of the application is a screw (1) with an optimized symmetrical thread for the installation of thermal insulation, has a shank core (2) equipped with a thread (3) and ends with a tip (4) tapering towards the apex angle (α) in the direction of screwing in, which is in the range from 40 ° to 50 °, the thread profile (3) being symmetrically triangular in the radial section is circumferentially helical with a pitch (S) corresponding to 0.35 to 0.55 of the diameter (d <sub> r </sub>) of the core (2) and has an vertex angle (φ) that is 45 ° to 55 °. The outer radius (R) of the thread (3) is 0.1 mm, while the diameter (d <sub> r </sub>) of the core (2) is smaller than the nominal diameter (d <sub> n </sub>) of the screw (1) in a proportion of 0.7 to 0.8.
