FIELD: building tools, particularly ones adapted to create guiding strips to level horizontal or vertical surfaces during finishing work performing. ^ SUBSTANCE: guide strip formation tool comprises laser level indicator, which indicates plumpness and levelness and alternately or simultaneously creates vertical and/or horizontal light lines, and guiding rule. Vertical and/or horizontal deviation of working surface is set with respect to vertical and/or horizontal light lines. Guiding rule consists of two strips, which may be displaced one relatively another. The first strip is shaping unit and provided with at least two spaced apart measuring scales drawn on outer surface thereof and extending in transversal direction. The second strip is stop. One strip is provided with through transversal guiding cuts. The first and the second strips are connected with each other by means of adjustable clips, which may be freely inserted in guiding slots and fastened to another strip through slotted strip. The first and the second strips are mutually arranged so that they coincide with each other in transversal and longitudinal directions. The second strip, namely stop, may abut working surface by longitudinal end surface thereof. Longitudinal end surface of the first strip faces working surface and is directed so that light line projects onto the first strip plane in longitudinal direction through selected measuring scale divisions. ^ EFFECT: increased usage convenience, decreased labor required for plastering execution due to increased tool simplicity and extended field of tool application. ^ 4 cl, 4 dwg |
