Abstract

Wzór użytkowy dotyczy konstrukcji elementu mocującego, znajdującego zastosowanie w budownictwie i w górnictwie. Element mocujący składa się z pręta (2) o powierzchni ryflowanej, oraz z rozpieraka (3). Pręt (2) na swobodnym końcu (2.3) ma wzdłużne, przelotowe szczeliny (2.5) wykonane wzdłuż prostopadłych do siebie i przecinających się w osi wzdłużnej (O<sub>2</sub>) pręta (2) płaszczyzn (A, B). Z kolei rozpierak (3) o postaci połączonych podstawami (3.1) stożków ściętych ma stożkową, tylną część (3.2) o mniejszej zbieżności i na jej obwodzie ma cztery wzdłużne, dwuścienne wycięcia prowadzące (3.4) o jednakowym kształcie. Każde z wycięć prowadzących (3.4) ma przekrój zasadniczo trójkątny, a jego dolna krawędź (3.5) usytuowana jest wzdłuż odpowiedniej płaszczyzny (M, N), które są prostopadłe do siebie i przecinają się w osi wzdłużnej (O<sub>3</sub>) rozpieraka (3). Dla rozparcia elementu mocującego w otworze, płetwy (3.6) rozpieraka (3) pod wpływem siły wzdłużnej wchodzą w przelotowe szczeliny (2.5), rozchylając na zewnątrz zakończenia (2.7) pręta (2), które rozpierają się o ścianki otworu.The utility model concerns the construction of a fastening element used in construction and mining. The fastening element consists of a rod (2) with a grooved surface and a spreader (3). The rod (2) at the free end (2.3) has longitudinal, through slots (2.5) made along planes (A, B) perpendicular to each other and intersecting in the longitudinal axis (O<sub>2</sub>) of the rod (2). . In turn, the spreader (3) in the form of truncated cones connected by their bases (3.1) has a conical rear part (3.2) with smaller convergence and on its circumference has four longitudinal, dihedral guide notches (3.4) of the same shape. Each of the guide slots (3.4) has a substantially triangular cross-section, and its lower edge (3.5) is located along an appropriate plane (M, N), which are perpendicular to each other and intersect in the longitudinal axis (O<sub>3</sub >) spreader (3). To expand the fastening element in the hole, the fins (3.6) of the expander (3) under the influence of longitudinal force enter the through slots (2.5), spreading outwards the ends (2.7) of the rod (2), which expand against the walls of the hole.
