Abstract

Przedmiotem zgłoszenia jest obudowa specjalna poszerzeń wyrobisk składająca się z zasadniczych odrzwi A, zawierających przynajmniej jeden łuk stropnicowy (3) i dwa łuki ociosowe (1) oraz z niepełnych odrzwi B, zawierających przynajmniej jeden łuk stropnicowy (3) i jeden łuk ociosowy (1), wykonanych z kształtowników V połączonych ze sobą znanymi metodami za pomocą znanych strzemion, lokalizowana pomiędzy sąsiadującymi odrzwiami obudowy łukowo-podatnej wyrobiska korytarzowego, która charakteryzuje się tym, że pomiędzy zasadniczymi odrzwiami A i niepełnymi odrzwiami B jest połączenie podatne oraz tym, że zasadnicze odrzwia A i niepełne odrzwia B zawierają się w jednej płaszczyźnie wspólnej.The subject of the application is a special support for the expansion of workings consisting of main arches A, containing at least one roof arch (3) and two side arches (1), and incomplete arches B, containing at least one roof arch (3) and one side arch (1). , made of V sections connected to each other by known methods using known stirrups, located between the adjacent arch support frames of the corridor workings, which is characterized by the fact that there is a flexible connection between the main frames A and the partial frames B and that the main frame A and incomplete doorways B are contained in one common plane.
