Method for displacing a ceiling formwork, collision protection element, and ceiling formwork, supporting device and incremental launching device comprising such a collision protection element

Method for shifting a ceiling formwork according to any of the preceding claims, wherein the ceiling formwork (10) is shifted from a first concreting cycle, comprising an at least partly concreted first concreting portion (8), into the next concreting cycle, wherein the next concreting portion (9) is arranged adjacently to the first concreting portion (8) in the shifting direction (VR), wherein

• a third support apparatus (13) for supporting the ceiling formwork (10) is arranged beneath the first concreting portion (8) adjacently to the first support apparatus (11) in the opposite direction to the shifting direction (VR),
• the third support apparatus (13) is placed in the dismantling position (AP),
• the ceiling formwork (10) is shifted by the ceiling formwork (10) first being supported at least in part by the third support apparatus (13) and the end face (17) of the ceiling formwork (10) then passing over the first support apparatus (11) and then the second support apparatus (12) in the shifting direction (VR), and
• the ceiling formwork (10) continues to be shifted into the next concreting portion (9) until a further end face (17′) of the ceiling formwork (10), said end face being oriented in the opposite direction to the shifting direction (VR), is released by the third support apparatus (13), or until just an end portion of the ceiling formwork (10) comprising the further end face (17′) of the ceiling formwork (10) is supported by the third support apparatus (13).

Anti-collision element (15, 15′) for preventing a collision of an end face (17, 17′) of a ceiling formwork (10), wherein the ceiling formwork (10) is supported by a first support apparatus (11) placed in a dismantling position (AP) and on a second support apparatus (12) placed in a shuttering position (EP) when the ceiling formwork (10) is shifted into a next concreting cycle comprising a next concreting portion (9) to be concreted, wherein the second support apparatus (12) is arranged with respect to the first support apparatus (11) in the direction of a shifting direction (VR) of the ceiling formwork (10), wherein the ceiling formwork (10) is lifted up to a concreting level when the ceiling formwork (10) is being supported by the support apparatus (11-14) in the shuttering position (EP), and, the ceiling formwork is lowered relative to the concreting level when the ceiling formwork is being supported by the support apparatus in the dismantling position (AP), wherein, when the end face (17, 17′) of the ceiling formwork (10) strikes the second support apparatus (12) after having passed over the first support apparatus (11), the anti-collision element (15, 15′) is arranged between the second support apparatus (12) and an end face (17, 17′) of the ceiling formwork (10) such that the anti-collision element (15, 15′) has a flank (15a) for guiding the ceiling formwork in the shifting direction (VR), said flank rising in the shifting direction (VR) and being formed, for example, as a solid or hollow body in a beak-shaped, cuneiform or skid-shaped manner or in the form of a ramp, and is designed to guide the end face (17, 17′) of the ceiling formwork (10) so as to lift it up to the concreting level such that the ceiling formwork (10) can pass over the second support apparatus (12).
