Geodetic marker

Abstract

The subject of the application is a geodetic signal comprising a longitudinal beam (1) equipped with coupling plates (4) at both ends, connected by means of mounting screws (6) to mounting plates (5) mounted on a measuring object (20). On the longitudinal beam (1) in its axis oo and at the same time in its central part, a cross beam (2) is centrally mounted by means of an axle (3), which has a protractor (15) in its central part and a semicircular element (7) with an arc cut-out (16), with a locking screw (17) embedded in it, allowing to determine the position of the said cross beam (2) in relation to the longitudinal beam (1) according to the indications of the protractor (15), while the semicircular element (7) in its external part is equipped with an angular scale (18) cooperating with an indicator placed on the post (19) of the longitudinal beam (1), on the said longitudinal beam (1) in its axis pp, at set distances from the axis oo, signaling devices (8) are placed on washers (12) in its initial and final part.The subsequent signals (8) are placed on at least one crossbeam (2), in its initial and final part, along its axis tt, at fixed distances from the axis oo, furthermore each signal (8) consists of a base (11), to which a display (9) is vertically attached, on which a drawing of a sign (10) is projected, the center of which is at a fixed height hj in relation to the base (11), the signals (8) are attached by means of coupling screws (13) to the longitudinal beam (1) rotatably around its own axes and to at least one crossbeam (2) rotatably around its own axes, and the angular position of the signals (8) is determined by means of indicators (14).
