International ClassG01C 15/00AbstractA method and remote-controlled reflector device for layout reference and axis lines is provided for use preferably in high building construction industry. The reflector device includes a mirror capable of rotating about its horizontal and vertical axes as controlled by an instrument man standing with a remote controller and a theodolite at a first location, such as on the ground or a lower floor of the building. The reflector device is positioned over the edge of a floor of a building under construction such as to be in direct view from both the first location and the second location where the new axis line marking are to be placed by the rod man. The mirror is first rotated by the instrument man such as to reflect the view from the theodolite back upon itself to verify its proper alignment with the base axis line. The instrument man then remotely rotates the mirror towards the second location such that the inflected line of sight is formed from the theodolite through the mirror defining an inflection point and advises the rod man where to place the mark for the new axis line. The procedure is then repeated at other locations as needed. The method allows more precise and safe transfer of lines without the need for the rod man to stand close to the edge of the building. Proper verification of the existing layouts is also described.Other References
