The ceiling shuttering system has a number of supports (1, 2), longitudinal (6) and cross bearers (3) and shuttering plates (4). On at least the lower side in the installation position of the longitudinal and cross bearers and/or the shuttering plates and/or the supports fixed positioning aids acting at regular distances optically and/or mechanically are fitted. The positioning aids are coloured markings. On the lower side in the installation position of the longitudinal and cross bearers and/or the shuttering plates raised formations or cavities are formed at regular distances. Such formations or cavities are conical. <IMAGE> |
