<p>The apparatus comprises a support (1) to which is suspended a rotary arm (2), attached to which is a leveling device (3). The support (1) is designed so that it can be arranged vertically and that the arm (2) can be secured by a wedge-shaped suspension unit (23). The arm (2) consists of two or several sections (21, 22), which are mutually connected in order to rotate in relation to one another. The leveling device (3) is fixed rotationally to the arm (2) and carries a distribution feed screw (32), which in the initial stage of the process can distribute the concrete or cement mortar (4) and can level the latter and smooth it in a second stage. The apparatus dispenses with the difficult task of smoothing the mortar in order to produce a floor base. In addition, it allows a considerably increased daily output compared with conventional means and processes.</p> |
