The device for measuring linear deformations of building materials according to the present invention comprises a base clamping plate (1) provided with a pair of grooves (2) (3) that are perpendicular to each other. In the longitudinal groove (3), there are movably mounted two laser sensors (5) and supporting points (6) for various lengths of the tested samples (7) and in the transverse groove (2), there is slidably mounted a supporting sheet metal (11) for various widths of the tested samples (7). In preferred embodiment, the laser sensor (5) is fixedly secured within a casing (4), which is attached to a steel angle (10), for setting the height of the laser sensor (5) casing (4) relative to the dimensions of the tested sample (7). The steel angle (10) is mounted slidably in the clamping plate (1) longitudinal groove (3) for setting arbitrary position relative to the dimensions of the tested sample (7) and measuring range of the laser sensors (5). |
