An apparatus for the application and surface-treatment of screed masses on floors comprises a bearing and supporting apparatus (1) which can be braced between the floor and ceiling, a cantilever (3) mounted pivotably on said apparatus, and a floor-working implement (9) located at the free cantilever end. The cantilever (3) is constructed in the form of a linked arm and for this purpose possesses a plurality of cantilever members (4) mounted so as to be able to pivot relative to one another. To permit extremely simple assembly and dismantling of the individual cantilever members with and from one another, in particular also with regard to a multiplicity of cantilever members, without affecting horizontal adjustment of the cantilever (3) overall, each cantilever member (4) is mounted on the preceding cantilever member (4) via a pivot fork (21). Whereas the upper end of the pivot shaft (29) can be inserted into a corresponding fitting hole in the upper fork arm (23) by a vertical movement, in the lower fork arm (25) a semicircular fitting hole (39) with an adjoining keyway (41) for a horizontal relative movement between two adjacent cantilever members (4) is provided (Fig. 2). <IMAGE> |
