DETAILED DESCRIPTION

[0174] Ceiling formwork systems, ceiling formwork panels, ceiling supports, and support heads and their mode of operation are known in principle from the general prior art, for example DE 10 2018 203 612 A1 and WO 2018/233993 A1, which is why only the features that are essential to the invention will be discussed in more detail below.

[0175] FIGS. 1 to 5 show a ceiling formwork system 1, in which four ceiling formwork panels 2 and a plurality of ceiling supports 3 are shown as an example.

[0176] The ceiling formwork panels 2 form a formwork in order to be able to create or pour a ceiling, in particular a floor ceiling, in particular made of concrete.

[0177] A support means 4 according to the invention is detachably fixed to an upper end of the ceiling supports 3. The support means 4 can also be designed in one piece with the ceiling support 3, in particular the upper end of the ceiling support 3.

[0178] In the exemplary embodiment according to FIG. 1 to FIG. 5, it is provided by way of example that each of the ceiling supports 3 shown there is provided with a support means 4 according to the invention. This is optional, however. If necessary, ceiling supports that are not provided with a support means 4 according to the invention can be used as well.

[0179] The ceiling supports 3 shown in FIG. 1 to FIG. 5 have a spindle device 5 in order to raise or lower the support means 4 as needed. Such spindle devices 5 are principally known from the prior art and typically have a spindle nut, by means of which the overall length of the ceiling support 3, in particular the support means 4, can be lengthened or reduced.

[0180] At their upper end, the ceiling supports 3 have a fastening element, preferably a fastening plate, to which the support means 4 can be fixed, preferably in a detachable manner, as will be explained in more detail below.

[0181] A support head 6 is arranged at an upper end of the support means 4 and engages in a basically known manner in a ceiling formwork panel 2 in order to hold said panel in position. In the exemplary embodiment, the support head 6 is detachably connected to the support means 4. Alternatively, however, the support head 6 can also be formed in one piece with the support means 4. A possible embodiment of a support head 6 is also shown in FIG. 21.

[0182] FIG. 6 to FIG. 23 show two advantageous embodiments of the support means according to the invention. In both embodiments, it is provided that the support head 6 can be releasably connected to the support means 4. However, the two exemplary embodiments are to be understood in such a way that the support head 6 can also be designed in one piece with the support means 4.

[0183] In principle, the support head 6 can be part of the support means 4.

[0184] As can be seen from FIG. 6 to FIG. 23, the support means 4 according to the invention has at least one upper elongated support element 7 and one lower elongated support element 8. The support elements 7, 8 are rotationally connected to each other.

[0185] FIG. 6 to FIG. 14 show an illustration of the support elements 7, 8 in a working position. In the working position, the longitudinal axes of the support elements 7, 8 preferably run parallel to one another so that the weight forces to be absorbed by the ceiling to be poured can be absorbed in an advantageous manner. In the exemplary embodiment, it is provided that the support elements 7, 8 or their longitudinal axes are aligned coaxially with one another.

[0186] The support elements 7, 8 can be rotated into a tilted position in which the support elements 7, 8 are rotated with respect to one another by a tilting angle α. FIG. 15 to FIG. 17 show the support elements 7, 8 in the tilted position.

[0187] In the exemplary embodiment, it is provided that the upper support element 7 is tilted while the position of the lower support element 8 remains unchanged, i.e., as before in the working position.

[0188] FIG. 5 shows how a support head 6 can be rotated outwards when the support elements 7, 8 are rotated relative to one another into a tilted position.

[0189] The support means 4 according to the invention has a locking element 9 which secures the support elements 7, 8 against a rotation in the working position.

[0190] FIG. 6 to FIG. 13 and FIG. 21 show the locking element 9 in the working position, in which it secures the support elements 7, 8 against rotation. As can be seen from the figures, the locking element 9 bridges a connecting region 10 between the two support elements 7, 8 in the working position. The connecting region 10 or the articulated connection between the upper support element 7 and the lower support element 8 is thus covered by the locking element 9 in such a way that the support elements 7, 8 cannot be rotated or are not rotatable into the tilted position.

[0191] As can be seen from FIG. 15 to FIG. 17 and FIG. 22, the locking element 9 can be brought into a release position, in which the locking element 9 is arranged outside the connecting region 10, i.e., in which the locking element 9 no longer bridges the connecting region 10 or releases the same.

[0192] In the exemplary embodiment, it is provided for this purpose that the locking element 9 is moved upwards from the working position until it has reached the release position, i.e., until the locking element 9 is outside of the connecting region 10.

[0193] In the exemplary embodiment, it is provided that the locking element 9 extends into the working position from a lower end region of the upper support element 7 to an upper end region of the lower support element 8 and thereby bridges the connecting region 10.

[0194] The exemplary embodiment also provides that the locking element 9 and the support elements 7, 8 are designed in such a way that the locking element 9 rests against an inner wall and/or an outer wall of the support elements 7, 8 in the working position. The exemplary embodiment shows that the locking element 9 rests against the outer walls of the support elements 7, 8 in the working position.

[0195] It is also provided in the exemplary embodiment that the locking element 9 forms a guide with the support elements 7, 8 in order to move the locking element 9 between the working position and the release position in a guided manner. This is preferably a linear guide that allows for the locking element 9 to be moved along the longitudinal axes of the support elements 7, 8, in particular in a coaxial manner.

[0196] In the embodiment shown in FIG. 6 to FIG. 13 as well as FIG. 22 and FIG. 23, it is provided that the locking element 9 and the support elements 7, 8 are designed such that, in addition to forming a linear guide, a guide is formed that secures the locking element 9 against rotation relative to the support elements 7, 8.

[0197] In the exemplary embodiments, it is provided that the outer diameters or the outer circumferences of the support elements 7, 8 are identical at least in the end regions of the support elements 7, 8 adjoining the connecting region 10. This makes it possible to move the locking element 9 back and forth between the working position and the release position in a particularly easy manner.

[0198] The exemplary embodiment also provides that the outside diameter of the connecting region 10 is the same as or smaller than the outside diameter of the lower end region of the upper support element 7 and/or the upper end region of the lower support element 8.

[0199] The features in the exemplary embodiment are to be understood in such a way that the support elements 7, 8 and also the locking element 9 can be designed as desired within the scope of the disclosure. The exemplary embodiment shows, however, a particularly preferred embodiment of the support elements 7, 8 and the locking element 9. The specific disclosure in the exemplary embodiment, however, is also to be understood as a general disclosure for a configuration of the support elements 7, 8 and the locking element 9.

[0200] In the exemplary embodiment, the upper support element is in the form of an upper support tube 7 and the lower support element is in the form of a lower support tube 8. Furthermore, the locking element is designed in the exemplary embodiment as a movable support sleeve 9.

[0201] The support sleeve 9 can also be a sliding sleeve.

[0202] The support sleeve 9 is designed such that, in the working position, as shown in FIG. 6 to FIG. 13, it encompasses, preferably tightly, the lower end region of the upper support tube 7 and the upper end region of the lower support tube 8, at least in portions. In the exemplary embodiment, the support sleeve 9, when in the working position, completely surrounds the lower region of the upper support tube 7 and the upper end region of the lower support tube 8 on the outside.

[0203] In the exemplary embodiments, the support sleeve 9 can be moved coaxially with respect to the upper support tube 7 and the lower support tube 8 in order to bring the support sleeve 9 into the release position.

[0204] In order to be able to move the support sleeve 9 in an easy manner, it preferably has an operating element, in particular an operating ring 9a, that runs about the outer wall of the support sleeve 9.

[0205] As can also be seen from the exemplary embodiments, the lower support tube 8 has a stop against which a lower front end of the support sleeve 9 rests in the working position. In the exemplary embodiment, the stop is designed as a stop ring 11 (e.g., FIG. 18) which runs about the outer circumference of the lower support tube 8 in the form of a ring or part of a ring.

[0206] The tilting angle a between the upper support element 7 and the lower support element 8 in the tilted position can be selected in such a way that it is ensured that the support head 6 is rotated outwards until the ceiling formwork panel 2, as shown in principle in FIG. 4 and FIG. 5, can be rotated downwards. It has proven to be particularly suitable if the tilting angle a is 5 to 90 degrees, preferably 10 to 80 degrees, more preferably 15 to 70 degrees, and particularly preferably 20 to 60 degrees, very particularly preferably 20 to 45 degrees, in particular 30 to 35 degrees, specifically 32.5 degrees. In the exemplary embodiment, an angle of 32.5 degrees is provided.

[0207] In the exemplary embodiment, no further intermediate positions are provided between the working position and the tilted position in which the support tubes 7, 8 are fixed or can be fixed to one another.

[0208] In the working position, the support tubes 7, 8 are fixed to one another by means of the support sleeve 9. In the tilted position, the support tubes 7, 8 are, due to gravity, in a stable position, which can be undone again by raising the upper support tube 7, preferably by hand, so that the upper support tube 7 runs again coaxial with the lower support tube 8 and can be secured by the support sleeve 9 in this position.

[0209] In the exemplary embodiment, the tilted position results from the fact that an upper front end of the lower support tube 8 has a bevel 12 or an angle cut. The bevel 12 is designed in such a way that 40% to 90%, preferably 50% to 90%, in particular 50% to 75%, of the upper front end of the lower support tube 8 is not provided with a bevel 12.

[0210] The bevel 12 can be seen particularly well in FIGS. 10, 11, 16 to 18, and 22. In the tilted position, a lower front end of the upper support tube 7 rests against the bevel 12, resulting in a stable positioning of the two support tubes 7, 8 in the tilted position.

[0211] In the exemplary embodiment, it is provided that the support tubes 7, 8 are rotatably connected to one another via an axis of rotation 13. For this purpose, it is provided that one of the support tubes, in the exemplary embodiment the lower support tube 8, has holes 14 in order to fix the axis of rotation 13. The holes are designed as elongated holes 14 in the embodiment.

[0212] The elongated holes 14 facilitate or support an advantageous rotation of the upper support tube 7 relative to the lower support tube 8. For this purpose, the upper support tube 7 is moved vertically to a slight degree or a small distance along the length of the elongated holes 14, resulting in a height difference compensation when tilted.

[0213] The elongated holes 14 also prevent forces from being transmitted to the axis of rotation 13 that passes through the elongated holes 14. For this purpose, it is preferably provided that the axis of rotation 13 always has vertical play in the elongated holes 14. The axis of rotation 13 is arranged in the elongated holes 14 in such a way that no forces, in particular no compressive forces, act on it when the support head 6 is in the working position, i.e., when it is not rotated. The axis of rotation 13 and the elongated holes 14 are therefore designed in such a way that the axis of rotation 13 has, in the working position, vertical play in the elongated holes 14 in the upward and preferably also in the downward direction.

[0214] This ensures that the compressive forces are only transmitted from the upper support tube 7 to the lower support tube 8.

[0215] The axis of rotation 13 is preferably designed as a bolt.

[0216] A connecting element 15 is fixed to the other support tube, in the exemplary embodiment the upper support tube 7. The connecting element 15 is shown in an individual representation in FIG. 20. In the exemplary embodiment, the connecting element 15 is fixed to an inner wall of the support tube 7. This is shown in particular in FIGS. 10, 11, 13, and 16, with FIGS. 10, 11, and 13 showing a design of the connecting element 15 that differs from that of FIG. 20.

[0217] To fix the connecting element 15 on the inner wall of the upper support tube 7, it can preferably be provided that the outer contour of the connecting element 15 is adapted to the radius of the inner wall of the support tube 7, for which purpose it can be sufficient, as shown in FIG. 20, if the longitudinal edges of the connecting element 15 are beveled or provided with a radius.

[0218] As shown in the exemplary embodiments, the connecting element 15 has one or more holes, in the exemplary embodiment exactly two holes 15a, through which the axis of rotation 13 fixed to the lower support tube 8 is guided in such a way that the connecting element 15 can be rotated about the axis of rotation 13.

[0219] As an alternative to the axis of rotation 13 and the elongated holes 14, a slotted guide can also be provided for carrying out the rotation movement.

[0220] In the exemplary embodiment, it is also provided that the connecting element 15 has holes 15b, by means of which the connecting element 15 can be fastened to the upper support tube 7.

[0221] In the exemplary embodiment, it is provided that the upper support tube 7 has holes 7a for attachment to the connecting element 15.

[0222] FIG. 6 to FIG. 14 and FIG. 22 to FIG. 23 show an embodiment of the support means 4 in which the outer circumference of the support tubes 7, 8 and the inner circumference of the support sleeve 9 have a noncircular cross section, in the exemplary embodiment a lemon-shaped cross section. Other cross-sectional shapes are possible as well, for example a polygonal cross section, a rectangular cross section, a square cross section, or a triangular cross section. Due to the fact that the support tubes 7, 8 and the support sleeve 9 have a cross section that is not circular and preferably lemon-shaped, torsional forces that can result from a twisting between the support tubes 7, 8 can be absorbed, whereby the stability of the support tubes 7, 8 is improved in particular in the working position and in particular makes it possible to avoid those forces, in particular the aforementioned torsional forces, that act on the axis of rotation 13 which can lead to damage there.

[0223] The exemplary embodiment according to FIGS. 15 to 19 and according to FIG. 21 shows a view in which the outer circumference of the support tubes 7, 8 and the inner circumference of the support sleeve 9 have a circular cross section. Such a design is particularly inexpensive.

[0224] It should be pointed out that, with the exception of these differences, all of the features illustrated in the exemplary embodiment can be realized in both exemplary embodiments without said realization requiring a separate mention.

[0225] In the exemplary embodiment, it is provided that the outer diameter of the support tubes 7, 8 with a circular cross section is 40 to 80 mm, preferably 40 to 70 mm, in particular 40 to 60 mm, preferably 50 mm±2 mm. If the cross section is not circular, in particular if the cross section is lemon-shaped, the length of a long axis of the cross section of the support tube 7, 8 can be 40 to 80 mm, preferably 40 to 70 mm, in particular 40 to 60 mm, preferably 51 mm±2 mm, and the length of a short axis of the cross section can be 5 to 25 mm, preferably 17 mm±2 mm shorter.

[0226] In both exemplary embodiments, it is advantageous if the wall thickness of the support tubes is at least 2.5 mm, preferably at least 3 mm, in particular at least 3.5 mm. Furthermore, it can be provided that the wall thickness is preferably less than 6 mm, in particular less than 5 mm, preferably less than 4.6 mm. Wall thicknesses between 3.5 mm and 4.5 mm, in particular 4.5 mm, are particularly advantageous. These values have proven to be particularly suitable for ensuring that, despite the bevel 12 in the working position, the weight of the ceiling to be poured can be reliably absorbed.

[0227] In both embodiments, it is advantageous if the support tubes 7, 8 together have a length of 200 to 600 mm, preferably 300 to 500 mm, more preferably 300 to 400 mm, very particularly preferably 340 to 360 mm, in particular 348.5 mm±2 mm. Furthermore, it has proven to be advantageous if the upper support tube 7 has a length that is greater than the length of the lower support tube 8. The length of the upper support tube 7 is preferably at least 1.5 times, preferably at least 1.8 times, the length of the lower support tube 8. It is also advantageous if the length of the upper support tube 7 is less than 4 times, preferably less than 3 times, the length of the lower support tube 8. It is advantageous if the length of the upper support tube 7 is 2 to 3 times, in particular 2 to 2.5 times, particularly preferably exactly 2 times, the length of the lower support tube 8.

[0228] In the exemplary embodiment, it is provided that the spindle device 5 is designed as part of the ceiling support 3. In principle, however, the spindle device 5 can also be part of the support means 4.

[0229] In the exemplary embodiment, the support means 4 is designed as an adapter or as an attachment for the detachable connection to an upper end of the ceiling support 3. For this purpose, a lower end region of the lower support tube 8 is designed with a lower adapter element 16 for a detachable attachment to the ceiling support 3. Alternatively, not shown in the exemplary embodiment, the ceiling support 3, an extension of the ceiling support 3, or a spindle portion, in particular a head spindle or the spindle device 5, can be formed on a lower end region of the lower support tube 8.

[0230] In the exemplary embodiment, it is also provided that an upper end region of the upper support tube 7 has an upper adapter element 17 for the detachable fixing of the support head 6 for the ceiling formwork panel 2. Alternatively, the support head 6 for the ceiling formwork panel 2 can be formed in one piece with the upper support tube 7 on the upper end region of the upper support tube 7 (not shown in the exemplary embodiment).

[0231] FIGS. 1 to 5 show the principle of a method for removing the ceiling formwork panels 2. For this purpose, it is provided that the ceiling support 3 is first lowered by means of the spindle device 5 until a support head 6 fixed to the support means 4 according to the invention, with which the ceiling support 3 is in engagement with the ceiling formwork panel 2, is disengaged or can be disengaged from the ceiling formwork panel 2. The support head 6 is then rotated by means of the support means 4 by a tilting angle α in such a way that the support tubes 7, 8 are rotated into the tilted position.

[0232] The support head 6 is rotated in such a way that the support head 6 is not in a rotation path of the ceiling formwork panel 2 when the support head 6 is rotated downwards about an axis of rotation that runs along a side edge of the ceiling formwork panel 2 that is not adjacent to the ceiling support 3. The result is shown in FIG. 5.

[0233] It should be pointed out that in order to carry out the method according to the invention, the spindle device 5 according to the invention with the two support tubes 7, 8 must not necessarily be used, but is preferred. A lowering can also be achieved with other support means that make it possible for the support head 6 to be lowered.

[0234] A particularly advantageous rotation of the support means 4 is shown below with reference to FIG. 1 to FIG. 5.

[0235] As shown, the ceiling formwork panels 2 preferably have a rectangular base region, which is usually formed by a formwork panel.

[0236] FIG. 1 to FIG. 5 show how the right front ceiling formwork panel 2 shown in FIG. 1 can be removed. The ceiling formwork panel 2 is rotated about one of the long side edges, in the exemplary embodiment about the left long side edge, which represents the axis of rotation of the ceiling formwork panel 2 in the context of the method.

[0237] In order to remove the ceiling formwork panels 2, as shown in FIG. 3, the two ceiling supports 3, which support the long left side edge of the ceiling formwork panels 2, are first lowered, preferably by approx. 20 to 30 mm, in particular 25 mm.

[0238] Then the two ceiling supports 3, which support the right long side edge of the ceiling formwork panel 2, are lowered, and preferably, the two ceiling supports 3 are lowered by 30 to 70 mm, preferably by 50 mm.

[0239] The right side of the ceiling formwork panel 2 is then raised and supported again by means of a positioning aid 18 or a raising aid. This situation, in which the right side of the ceiling formwork panel 2 is raised by means of the positioning aid 18, is shown in FIG. 4.

[0240] The positioning aid 18 is usually a telescoping rod with a head that is suitable for engaging the underside of the ceiling formwork panels 2.

[0241] By lowering the ceiling support 3 by preferably 50 mm and then raising the ceiling formwork panel 2 again using the positioning aid 18, as can be seen from FIG. 4, the support head 6 is disengaged from the ceiling formwork panel 2 or the support head 6 is exposed. This is shown accordingly in FIG. 4.

[0242] In the exemplary embodiment, the ceiling supports 3 are lowered by means of the spindle device 5. The spindle device 5 can preferably have a head spindle.

[0243] The support head 6 is then rotated by means of the support means 4 by a tilting angle a in such a way that the support head 6 is no longer in a rotation path of the ceiling formwork panel 2. This is shown in FIG. 5. The rotation path of the ceiling formwork panel 2 results from the fact that the ceiling formwork panel 2 is rotated downwards about an axis of rotation, in the exemplary embodiment the left long side edge of the ceiling formwork panel 2.

[0244] FIG. 5 shows a situation in which the ceiling formwork panel 2 has already been rotated downwards. The ceiling formwork panel 2 can then be unhooked and transported away in a known manner.

[0245] Before the head 6 is rotated by a tilting angle α, the support head will preferably be lowered by 25 mm to 500 mm, in particular 50 mm to 400 mm. It has proven particularly suitable if it is lowered by 25 mm to 100 mm, preferably 35 mm to 70 mm, particularly preferably 40 mm to 55 mm. This also makes it possible for the support head 6 to be released and then rotated.

[0246] The order of mounting the ceiling formwork panel 2 and its positioning can be reversed. It is thus possible to carry out both the positioning and the removal process from a safe position from below.

[0247] In order to make it possible for the support head 6 to be rotated, it is provided in the exemplary embodiment that the support means 4 is designed in such a way as was described above with reference to the support means 4 according to the invention. The support means 4 can be operated in a particularly simple manner by manually pushing the support sleeve 9 upwards in order to unlock the support tubes 7, 8 that are in the working position and then, preferably also manually, rotate the upper support tube 7 into the tilted position.

[0248] The method according to the invention, as described with reference to FIG. 1 to FIG. 5, can also be carried out with a support means that has a different rotation mechanism.
