DETAILED DESCRIPTION
(23) FIG. 1 shows a ceiling formwork system 100 supported by ceiling supports 1. Ceiling formwork system 100 comprises, in addition to a ceiling formwork 2, a plurality of elements of a side protector 3. Ceiling formwork 2 comprises a plurality of formwork elements 4. Two side protectors 3 each are installed on some of the plurality of formwork elements 4.
(24) Formwork elements 4 are designed in the shape of frame panel formwork elements. Formwork elements 4 have a frame 5 and a formwork shell 6. Formwork elements 4 are oriented with their formwork shell 6 directed upward and are laterally joined to each other. Formwork elements 4 have a longitudinal side and a transverse side. Correspondingly, frame 5 has two longitudinal frame parts 7 extending parallel to each other and two transverse frame parts 8 extending parallel to each other. Longitudinal frame parts 7 and transverse frame parts 8 are oriented perpendicular to each other. Longitudinal frame parts 7 have double the length of transverse frame parts 8. Longitudinal frame parts 7 extend on the longitudinal side of formwork element 4. Transverse frame parts 8 extend on the transverse side of element part 4.
(25) Side protector 3 has a pivoting frame 10, a railing 11 and a mounting rail 9. Mounting rail 9 is arranged below ceiling formwork 2, covered by formwork shell 6 and is indicated in FIG. 1 by a black bar (mounting rail 9). Railing 11 is connected to pivoting frame 10.
(26) If, as depicted in FIG. 1, side protectors 3 are provided laterally with respect to the longitudinal side of formwork elements 4 arranged in the edge region of ceiling formwork 2, two mounting rails 9 each are installed next to each other on the longitudinal frame part 7 facing the longitudinal side to be protected of third formwork element 4—as seen from the longitudinal side of formwork element 4 to be protected.
(27) If side protectors 3 are provided laterally with respect to the transverse side of formwork elements 4 arranged in the edge region of ceiling formwork 2 (not shown in FIG. 1), then mounting rail 9 is installed on the transverse frame part 8 facing toward the transverse side to be protected of second formwork element 4—as seen from the transverse side to be secured of formwork element 4.
(28) After installation of mounting rail 9 on frame 5 of formwork element 4, pivoting frame 10 is hooked into mounting rail 9 from the ground and is pivotably mounted there about an axis of rotation A opposite mounting rail 9. Immediately after being hooked in, pivoting frame 10 is first positioned in an installation position. In the installation position, pivoting frame 10 is hooked into mounting rail 9, but not swung up. Pivoting frame 10 is then swung up from this installation position about an axis of rotation A into an end position. In the end position, side protector 3 laterally secures ceiling formwork 2 by railing 11. In the end position, side protector 3 projects upward with its railing 11 out over ceiling formwork 2.
(29) FIG. 2 shows pivoting frame 10. Pivoting frame 10 has a pivoting base frame 14 and a pivoting flap 15. Pivoting base frame 14 has two longitudinal members 16 arranged parallel. Longitudinal members 16 are designed as hollow profiles having a rectangular cross-section. Longitudinal members 16 each have a first longitudinal member part 17 and a second longitudinal member part 18. Second longitudinal member part 18 is arranged at an angle of 90 degrees with respect to first longitudinal member part 17. First longitudinal member parts 17 are connected to each other via crossbeams 19. Crossbeams 19 have a square cross-section. A through-hole 13 is provided in the end area of each first longitudinal member part 17 A pin 20 is arranged in through-hole 13 that extends through corresponding first longitudinal member 17 and projects from first longitudinal member 17 on both sides. The longitudinal axis of pin 20 that extends through the passage of one of the two first longitudinal member parts 17 and the longitudinal axis of pin 20 that extends through the passage of the other of the two first longitudinal member parts 17 are within the same axis of rotation A. Second longitudinal member parts 18 are connected to each other via a transverse connector 21. Transverse connector 21 is designed as a round rod/tube.
(30) In a further embodiment shown in FIGS. 19 and 20, pin or pins 20 are not designed or arranged in longitudinal member parts 17 but are rigidly fixed in end areas of spacer support pieces that are oriented upward at a right angle in the extension direction of second longitudinal members 18 at the ends of longitudinal member parts 17. In this embodiment, the spacer support pieces are also provided in the area between longitudinal member parts 17 and longitudinal member parts 18. The embodiment shown in FIG. 2 and the embodiment shown in FIG. 19 can be mounted overlapping each other on the bottom side of formwork elements 4 without colliding with each other. If these two embodiments are combined, the side protector according to the invention can also be mounted in corner areas of adjacent transverse and longitudinal sides of formwork segments 4, and a side protector all around ceiling formwork 2 (completely) is also possible.
(31) Pivoting base frame 14 having pivoting flap 15 is pivotably connected about axis of rotation B in the end region of second longitudinal member 18. Pivoting flap 15 has two side parts 22 that are connected to each other via two additional crossbeams 23. Side parts 22 are designed as flat plates that have a profiling in a side area. The profiling is designed as step 24 for bearing on the top side of formwork 4 (FIG. 1). One of the additional crossbeams 23 connects side parts 22 in the end area of pivoting flap 15. This additional crossbeam 23 has a coupling element 25. A locking element 25 is pivotably articulated at coupling element 26 about an axis of rotation C. Locking element 26 comprises two identically designed side plates 27 that each have a lug 28 and are connected to each other by a connecting plate not shown in FIG. 2. Coupling element 25 is arranged between two side plates 27 of locking element 26 and is pivotably mounted via an additional pin 30 that extends through side plates 27 of locking element 26 and coupling element 25.
(32) FIG. 3 shows mounting rail 9 in a perspective representation. Mounting rail 9 has a beam 31, in each of whose end areas is arranged a pair of mounting brackets 32 and in whose center is arranged a securing flap 33. Beam 31 is designed as a hollow profile and has a square cross-section. Mounting brackets 32 are formed as flat, essentially S-shaped plates and have first notches 34 on their ends facing away from beam 31 for receiving a corresponding pin 20 that extends through first longitudinal member part 17 (FIG. 2). Each of the mounting brackets 32 forms an additional second notch 35 with beam 31 for engaging behind a projection of frame 5 (FIG. 1). Securing flap 33 has an abutment element 37 and a locking lever 38 pivotably connected to beam 31 for fastening mounting rail 9 onto frame 5 (FIG. 1). Abutment element 37 is designed as a flat, essentially sickle-shaped plate. Just as mounting brackets 32 with beam 31, abutment element 37 forms an additional notch 35 with beam 31 for engaging behind the projection of frame 5 (FIG. 1). Abutment element 37 has a wedge-shaped taper 39 at its one end for engaging in a passage opening 40 of frame 5. Securing lever 38 is pivotably connected to beam 31. For this purpose, securing lever 38 has an additional passage 41 and beam 31 has an additional pin 42. Additional pin 42 arranged on beam 31 extends through additional passage 41 of securing lever 38. A release of securing lever 38 from additional pin 42 is prevented by a cotter pin 43 inserted into additional pin 42.
(33) In a resting position of securing lever 38, in which it is oriented transverse to beam 31, securing lever 38 blocks additional notches 35. Securing lever 38 projects over the surface of beam 31 with a free end. An insertion of the projection of frame 5 into additional notches 35 is consequently not possible. FIG. 3 shows securing lever 38 in its resting position (blocking position). If mounting rail 9 is mounted on frame 5 and securing lever 38 is in the position shown in the figure, mounting rail 9 cannot be removed.
(34) FIG. 4 shows a mounting rail 9 connected to frame 5 having a securing lever 38 oriented parallel to beam 31. In order to install mounting rail 9 on frame 5, securing lever 38 is pivoted far enough out of its resting position—against a spring force, for example—that it is oriented parallel to beam 31. This makes it possible to insert the projection of frame 5 into additional second notches 35. At the same time, the wedge-shaped taper 39 of abutment element 37 is inserted into passage opening 40 of frame 5. Mounting rail 9 is thus also stabilized on frame 5.
(35) FIG. 5 shows the engagement of projection 36 of frame 5 through mounting brackets 32 and beam 31, as well as abutment element 37 that, with beam 31, forms an additional notch 35. Securing lever 38 is oriented parallel to beam 31 so that mounting rail 9 can be fitted on frame 5 and mounted securely there via a placement of securing lever 38 in its resting position.
(36) FIG. 6 shows mounting rail 9 connected to frame 5 having securing lever 38 in resting position. After projection 36 on the interior of frame 5 is fully inserted into additional second notches 35, securing lever 38 is again pivoted back into its resting position, for example automatically by spring force. An outer side of frame 5 opposite projection 36 of frame 5 comes to rest against securing lever 38 when projection 36 of frame 5 slips out of the additional second notches 35, whereby a slipping of projection 36 of frame 5 out of the additional second notches 35 is prevented. Mounting rail 9 is thus fixed on frame 5, meaning captively secured.
(37) FIG. 7 and FIG. 8 show a pivoting frame 10 in installation position with its pins 20 in mounting brackets 32 of mounting rail 9. In order to connect pivoting frame 10 to mounting rail 9, pins 20 extending through first longitudinal member part 17 are mounted in first notches 34 in mounting brackets 32. The two first longitudinal member parts 17 are each arranged for this purpose between one of the pairs of mounting brackets 32. Here, one mounting bracket 32 is to be mounted on each side of the corresponding longitudinal member part 17. Pin 20 extending away on both sides of corresponding first longitudinal member part 17 is pivotably mounted about an axis of rotation A in first notches 34 of the pair of mounting brackets 32 and rests on each side of corresponding longitudinal member part 17 in a first notch 34 of a mounting bracket 32.
(38) FIG. 9 shows a railing 11. Railing 11 has two longitudinal struts 44. Longitudinal struts 44 are connected to each other via a plurality of transverse struts 45. The connection of longitudinal struts 44 to transverse struts 45 results in a grid. Longitudinal struts 44 and transverse struts 45 are designed as hollow profiles.
(39) FIG. 10 shows a railing 11 connected to a pivoting frame 10 arranged in the installation position. Railing 11 is mounted in pivoting frame 10. For this purpose, railing 11 is mounted having each one of its longitudinal struts 44 inserted into one of each of second longitudinal member parts 18 designed as a hollow profile.
(40) FIG. 11 shows a railing 11 connected to pivoting frame 10, wherein pivoting frame 10 is pivoted out of the installation position in the direction of the end position.
(41) FIG. 12 shows pivoting frame 10 pivoted almost into its end position in a cutaway section in the area of railing 11/pivoting frame 10.
(42) FIG. 13 shows parts of pivoting frame 10 pivoted almost into its end position in a cut representation from the side having locking element 26.
(43) FIG. 14 shows pivoting frame 10 pivoted almost into its end position in a perspective view from above. In FIG. 12, FIG. 13 and FIG. 14, pivoting flap 15 is not fully pivoted about axis of rotation B in the direction of pivoting frame 10 and lug 28 of locking element 26 does not engage behind the closest of the plurality of crossbeams 19.
(44) FIG. 15 shows pivoting frame 10 in its end position on the transverse side of a formwork element 4 having locking element 26 engaged behind the closest of the plurality of crossbeams 19.
(45) FIG. 16 shows a perspective view of pivoting frame 10 in its end position having locking element 26 engaged behind the closest of the plurality of crossbeams 19.
(46) FIG. 17 shows a cutaway view from the side of pivoting frame 10 in its end position with locking element 26 engaged by its lug 28 behind the closest of the plurality of crossbeams 19.
(47) FIG. 18 shows a perspective view from below of pivoting frame 10 in its end position with locking element engaged by its lug 28 behind the closest of the plurality of crossbeams 19. If pivoting frame 10 is fully pivoted into the end position, first longitudinal member parts 17 are oriented essentially parallel to formwork elements 4. For securing pivoting frame 10 in this position to formwork element 4, pivoting flap 15 is fully pivoted with respect to pivoting frame 10 about axis of rotation B in the direction of pivoting frame 10. Step 24 designed in each of side parts 22 of pivoting flap 15 (see FIG. 16) thus comes to rest on the top side of formwork 4, whereby pivoting frame 10 is supported on formwork 4. Simultaneously, lug 28 engages behind the closest of the plurality of crossbeams 19 and locks to this, whereby a slippage of step 24 built into each side part 22 of pivoting flap 15 from the top side of formwork element 4 is prevented.
(48) FIG. 19 shows a second embodiment of a pivoting frame 50 having spacer support pieces 52, 54, 56, 58 that are provided on first longitudinal member parts 17′ and second longitudinal member parts 18′. Pins 20′ that form axis of rotation A between pivoting frame 50 and the mounting rail not shown in the figure are designed in the end area of spacer support pieces 52, 54.
(49) All further embodiments of pivoting frame 50 correspond to the technical embodiments as they are described in FIG. 2, in particular, and to pivoting frame 10 in FIGS. 1 to 18.
(50) FIG. 20 shows in a side view how two pivoting frames cross over each other and are mounted on the bottom side of formwork elements.
(51) Formwork elements 4 form and illustrate the cutaway section of a ceiling formwork. Mounting rails 9 are installed on a longitudinal side as well as on a transverse side on the bottom side of the formwork elements, as described in the figures. On the longitudinal side, pivoting frame 50 is mounted in mounting rail 9 and pivoting frame 10 is pivotably mounted in the other mounting rail 9 shown. Pivoting frame 50 is also held pivotably guided by pins 21 that are formed in support spacer piece 52.
(52) In FIG. 20, Support spacer piece 56 is shown that enables a pivotable side part 22′ to engage with a formwork element 4 on the top side of formwork element 4. Side part 22′ is shown in the locked position and holds the side protector securely on the edge of the formwork. The longitudinal side with railing 11 is secured via pivoting frame 50.
(53) Pivoting frame 10 that secures the transverse side of a ceiling formwork via a railing 11 is mounted between pivoting frame 50 and the bottom side of formwork element 4. FIG. 20 shows a corner covering with a side protector on each of the transverse and longitudinal sides.
(54) A side protector 3 is disclosed for a ceiling formwork 2. Ceiling formwork 2 comprises at least one formwork element 4 with a frame 5. Side protector 3 has a railing 11. Side protector 3 further has a pivoting frame 10. Railing 11 is connected to pivoting frame 10. Pivoting frame 10 can be connected to frame 5 in a direct or indirect manner from the bottom side of ceiling formwork 2. Pivoting frame 10 can be pivoted from an installation position about an axis of rotation A into an end position in such a manner that ceiling formwork 2 is laterally secured by railing 11. In addition, a ceiling formwork system 100 having at least one corresponding side protector 3 and one ceiling formwork 2 is specified. A method for erecting such a side protector 3 is also specified.
