Abstract
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 asymetrycznie 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 asymetryczny kąt wierzchołkowy, który wynosi od 25° do 35°, a kąt gwintu (3), od strony przeciwnej do kierunku wkręcania stanowi od 0,1 do 0,2 kąta wierzchołkowego. 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 screw (1) with an optimized symmetrical thread for the installation of thermal insulation has a shank core (2) equipped with a thread (3) and ended with a tip (4), tapering in the direction of screwing in at the apex angle (α), which is in the range from 40 ° to 50 °, the thread profile (3) being asymmetrically 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 asymmetric point angle ranging from 25 ° to 35 °, and the thread angle (3), on the side opposite to the screwing direction, is from 0.1 to 0.2 point angle. 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.
