Abstract

Przedmiotem zgłoszenia jest obudowa podporowa, która zawiera dwie usytuowane naprzeciw siebie podpory (1, 2) oraz umieszczony pomiędzy nimi segment łukowy (3) tworzące portal. Zarówno podpory (1, 2) jak i segment łukowy (3) są utworzone z profili mających w przekroju poprzecznym kształt litery „U” o poziomej osi obojętnej i pionowej osi symetrii dzielącej profil na pierwsze ramię i symetryczne do niego, przeciwległe drugie ramię, przy czym pierwsze i drugie ramiona profili podpór (1, 2) i segmentu łukowego (3) są skierowane na zewnątrz portalu, a położenie pierwszych i drugich ramion profili podpór (1, 2) odpowiada położeniu pierwszych i drugich ramion profilu segmentu łukowego (3). Segment łukowy (3) zachodzi z zakładem na każdą z podpór (1, 2) i w obszarze zakładu jest połączony z podporą (1, 2) za pomocą co najmniej zacisku ruchomego (5a) usytuowanego przy końcu podpory (1, 2) i zacisku nieruchomego (5b) usytuowanego przy końcu segmentu łukowego (3), przy czym każdy zacisk nieruchomy (5b) ma otwór mocujący (22). W podporach (1, 2) oraz segmencie (3) utworzone są otwory (10) dla kotew, przy czym w każdej podporze (1, 2) utworzone są co najmniej dwa otwory (10) dla kotew, a w segmencie łukowym (3) utworzony jest co najmniej jeden otwór (10) dla kotwy. Każdy otwór (10) dla kotwy jest usytuowany na przecięciu osi obojętnej i pierwszego lub drugiego ramienia profilu, natomiast oś wzdłużna otworu (10) dla kotwy rozciąga się w kierunku obszaru pomiędzy końcem pierwszego i drugiego ramienia profilu.The subject of the application is a support housing which comprises two oppositely located supports (1, 2) and an arch segment (3) placed between them, forming a portal. Both the supports (1, 2) and the arch segment (3) are formed of profiles having a U-shaped cross-section with a horizontal neutral axis and a vertical axis of symmetry dividing the profile into a first arm and a symmetrical, opposite second arm, wherein the first and second arms of the support profiles (1, 2) and the arch segment (3) are directed outwards from the portal, and the position of the first and second arms of the support profiles (1, 2) corresponds to the position of the first and second arms of the arch segment profile (3). The arch segment (3) overlaps each of the supports (1, 2) and is connected to the support (1, 2) in the overlap region by means of at least a movable clamp (5a) located at the end of the support (1, 2) and a fixed clamp (5b) located at the end of the arch segment (3), each fixed clamp (5b) having a fastening hole (22). Anchor holes (10) are formed in the supports (1, 2) and the segment (3), at least two anchor holes (10) being formed in each support (1, 2) and at least one anchor hole (10) being formed in the arch segment (3). Each anchor hole (10) is located at the intersection of the neutral axis and the first or second profile arm, while the longitudinal axis of the anchor hole (10) extends in the direction of the area between the end of the first and second profile arm.
