A mounting structure for an element (1) which is to be given a fixed setting. The mounting structure is intended to be mounted on a building, building part, base structure etc. The characteristic feature of the mounting structure is an axle (5) which is mounted both rotatable in and essentially vertically at a holder (4) which in turn is mounted on the building or equivalent structure, an azimuth angle rough-adjustment member being thereby formed. An azimuth angle fine-adjustment member (18) includes a slab (10) which is rotatably mounted on a transverse beam (6) fixed on the axle (5) and which rotates around a pivot pin disposed between the beam and the slab. The element (1) is mounted rotatable on the slab by means of two pivot pins (16) the longitudinal axes of which coincide with and intersect the longitudinal axis of the pivot pin. An elevation angle adjustment member (29) of variable length which extends, in a way well-known in itself, between a fixed point of the element (1) and a point of the axle (5) is articulately fixed at each one of these points. The joint with the element permits turning of the element in the azimuth and elevation directions, whereby when operating the azimuth angle fine-adjustment member (18) the element (1) turns around an imaginary axis (AZf) which passes through the pivot pin and the joint (31) of the elevation angle adjustment member with the element (1). |
