Apparatus for passively supporting overhead solids (2, 3) typically located in a mine, above a floor (5) are described. The apparatus comprises an arrangement of three generally H-shaped beams (7-9) formed as a right-sided archway. The near vertically arranged beams (8, 9) stand from the floor (5) by footings (8a, 9a). The near horizontal beam (7) is secured to the vertically arranged beams (8, 9) by corner braces (7a) and associated locking bolts. Each of the beams (7-9) has a plurality of spaced-apart keyhole-shaped locking points (10) from which can be hung mining services such as pipes (12, 13) by means of a linked chain (11). By choice of appropriate locking points (10) a service can be supported with appropriate alignment.
Appareil de soutien passif pour structures solides en surplomb (2, 3) habituellement situées dans une mine au-dessus d'un plancher (5). L'appareil comporte un ensemble de trois profilés en H (7-9) constituant une arcade à montants verticaux. Les profilés sensiblement verticaux (8, 9) prennent appui sur le plancher (5) par l'intermédiaire de socles (8a, 9a). Le profilé sensiblement horizontal (7) est fixé aux profilés verticaux (8, 9) par des écharpes (7a) et des boulons de blocage associés. Chacun des profilés (7-9) présente une pluralité de points de fixation (10) en forme de trou de serrure espacés les uns des autres et adaptés pour recevoir des dispositifs auxiliaires suspendus tels que des tuyaux (12, 13) maintenus par une chaîne à maillons (11). Un choix approprié des points de fixation (10) permet l'alignement correct d'un dispositif auxiliaire.
