The invention relates to construction, in particular to devices for cutting building materials.The device for cutting building materials contains an operating base (1) with a rest (15) and a gauge staff (16), on which are mounted two spring-loaded platforms (12), between which is fixed a supporting edge (2). On the columns (3), installed from the end faces of the operating base (1), is fixed a profiled guide rail (4), the vertical plane of which coincides with the vertical plane of the supporting edge (2), on the profiled guide rail (4) is mounted with the possibility of longitudinal movement a cutting carriage (5) on rollers (8). The rollers (8) are installed on bearings and correspond to the profile of the guide rail (4), from the end faces of which in supports are mounted breaking elongated two-stage tabs (7), symmetrically placed with respect to the cutting carriage (5), between which is placed a roller cutting blade (6), and in the upper part of the cutting carriage (5) on the axis is fixed a lever (10) with handle (11), connected by rods (9) to the breaking elongated two-stage tabs (7). |
