    Summary
    A device for determining the center coordinates (xi, yt) of circular wall holes (L) is described. This device is characterized by a gauge (1) that can be attached to the wall and has a V-shaped cutout (3) delimited by two angle legs (2), a measuring ruler (5) in the extension of the angle symmetry (4) between the two angle legs ( 2) and two vials (6, 7), one of which is arranged parallel and the other perpendicular to the measuring ruler (5).

    The invention relates to a device for determining the center coordinates of circular wall holes.
    In order to be able to cut and process cladding elements, for example ceramic tiles according to a given wall structure, it is known (AT 514 552 B1) for measuring surface points that determine wall boundaries, projecting and projecting wall parts, openings for different installations or wall openings on the wall project the axes of a reference coordinate system in order to be able to measure the coordinates of these surface points with respect to the projected horizontal and vertical axis of the reference coordinate system. Difficulties here are wall holes with a usually circular cross section, because the center coordinates of the circular openings, which clearly determine the position of these wall holes, cannot be easily measured.
    The invention is therefore based on the object of providing a device which can be used to determine the center coordinates of circular wall openings with little effort.
    The invention solves this problem by a wall-mounted gauge, which has a V-shaped cutout delimited by two angle legs, a measuring ruler to extend the angular symmetry between the two angle legs, and two vials, one of which is parallel and the other perpendicular to the measuring ruler are arranged.

    If such a teaching is applied to a circle in such a way that the two angle legs delimiting the V-shaped cutout form tangents to the circle, the angular symmetry between the two angle legs runs through the center of the circle. Provided that the teaching is applied to the wall hole in such a way that the angular symmetry runs vertically and then horizontally through the center of the circle, the vertical angular symmetries give the horizontal and the horizontal angular symmetry the vertical coordinate of the center of the circle in relation to a reference coordinate system with horizontal and vertical coordinate axis. It is therefore only necessary to apply the gauge horizontally and on the other hand vertically, which is used as a spirit level, only in the two aligned positions in the area of the V-shaped cutout tangentially to the circular wall hole in order to follow the measuring ruler on the wall that extends in the angle symmetry To be able to draw measurement lines that reflect the coordinates of the center of the circular wall hole.
    Although the opening angle of the V-shaped section of the gauge can be chosen as desired, if only it is ensured that the two angle legs of the section encompass the circular wall holes tangentially, there are particularly simple constructional relationships if the two angle legs of the V-shaped section form a right angle lock in.
    The subject matter of the invention is shown in the drawing, for example, and a device according to the invention for determining the center coordinates of circular wall holes is shown in a plan view in two measurement positions.
    A device according to the invention for determining the coordinates of the center M of a wall hole L with a circular cross section, for example an installation box, comprises a jig 1 which can be placed on the wall and which has a V-shaped cutout 3 delimited by two angle legs 2 and a / 6 in FIG
    Extension of the angular symmetry 4 between the two angle legs 2 arranged measuring ruler 5.
    Although the measuring ruler 5 in the exemplary embodiment shown is designed as an edge that a measuring line can be drawn along on the wall, this configuration is not mandatory. For example, the measuring ruler 5 could also be in the form of a marking slit through which the measuring line can be drawn on the wall.
    To align the gauge 1 with respect to a horizontal and a vertical reference axis, the gauge 1 is provided with two vials 6, 7 each forming a spirit level, of which one vial 6 runs parallel to the measuring ruler 5 and the other vial 7 perpendicular to it.
    To determine the coordinates of the center M of the wall hole L, the gauge 1 is first applied to the wall hole L in an aligned position, for example in the drawing the horizontal position shown in full lines, which is determined by the dragonfly 6, so that the two Angle leg 2 touch the circular edge of the wall hole L tangentially. In this position of gauge 1, a measuring line 8 can be drawn on the wall along the measuring ruler 5. After the jig 1 has been rotated by 90 ° and has been appropriately aligned using the spirit level 7, the measurement line 9 is drawn under analogous conditions. The measuring lines 8 and 9 thus indicate the coordinates xi and y1 of the center M of the wall hole L in relation to a coordinate system with the coordinate axes x and y, which is indicated by dash-dotted lines and z. B. is projected onto the wall using a laser system.
