    The plastic dowel pin for screwing and unscrewing prefabricated concrete sections, and preferably concrete sleepers for railway track, has an outer thread (1) and an internal thread (2). The head of the dowel pin has no threading and is in the shape of a multi-sided hollow prism (3) inside, or outside, preferably hexagonal. The plastic dowel pin is rapidly screwed and unscrewed, mechanically. A section joined to the screwing spindle of the screwing mechanism is dropped into or onto the multi-sided prism, enabling the dowel pin to be turned. Before screwing in the dowel pin, it is inserted by hand into the threaded hole of the concrete section.

    (54) DUBEL
    one
    This invention relates to superstructure elements.
    Known dowel having solderless threaded and threaded parts, ij.
    However, the disadvantage of this dowel is the large amount of time it takes to install and remove it from the sleeper.
    The purpose of the invention is to increase labor productivity by reducing the time to install the dowel.
    This goal is achieved by the fact that the inner surface of the threadless part has the shape of a polyhedron, mainly a hexagonal prism.
    -And the outer surface of the threadless part has the shape of a multifaceted prism ..
    FIG. 1 shows the proposed dowel, general view; in fig. 2 - dowel with hexagonal hollow prism, v.plan; in fig. 3 - dowel with a multifaceted prism, in plan.
    The proposed dowel has nojaie trackless 1 and threaded 2 parts. The threadless part has an inner and outer surface. The outer surface has a multifaceted prism 3. The inner surface has a hexagonal prism 4. A dowel is replaced by a wrapping mechanism, which is made in the form of a dowel and is inserted into it. prism 4 or worn on prism 3,
