The invention relates to an improved concrete-spreading and -smoothing tool. The invention consists of a scraper drag comprising a ladle (2), two runners (3) and a handle (5). The aforementioned ladle (2) comprises a rectangular metal sheet having two folds such as to form three parts, namely: a central section (2.2), a large section (2.1) and a small section (2.3). According to the invention, each part of the scraper drag has a determined function, i.e. the large section is used to distribute the concrete, the central section is used to smooth the concrete and the small section prevents the central section from penetrating the concrete during the smoothing process, owing to the angle of inclination thereof in relation to said central zone. Moreover, the circular runners (3) are used for two functions, namely: to facilitate the sliding of the scraper drag over the iron framework and, depending on the size thereof, to determine the height of the compression layer. |
