Definitions
- the invention relates to a slab formwork system with a plurality of formwork elements, which have on its underside with heads of vertical supports coupled carrier.
- Such a slab formwork system is known from document EP 0 130 425 A1.
- This system consists of formwork panels, on whose underside C-shaped supports are arranged, which can be hooked in a substantially vertical orientation of the formwork panels with a head of a vertical support, after which the scarf panels can be pivoted while maintaining the hook connection in a horizontal position.
- the base portion of the C-shaped support is provided with an opening into which a fixing element can engage, which is fixedly connected to the head of the vertical support.
- a disadvantage of the known slab formwork system is the fact that mounted on the vertical supports shuttering elements can solve easily with appropriate force from the vertical supports, which can cause a significant risk of accidents.
- An object of the invention is to provide a ceiling formwork system of the type described above in such a way that there is a reduced risk of accidents.
- This object is achieved by the features of claim 1 and in particular by the fact that the head of a vertical support has a support of a formwork element in the vertical direction fixing lift-off, wherein the head of a vertical support in addition Fixierele- elements, which is a movement of the carrier in the longitudinal direction prevent relative to the head.
- the anti-lifting device ensures that a scarf element once coupled with a vertical support can not subsequently be loosened or displaced in an unintentional manner by the vertical support by movement of the formwork element substantially upwards or in the longitudinal direction of the support. This is particularly during the assembly or disassembly phase, ie before or after the application of the concrete to the slab formwork system, an advantage, since in certain situations can act on vertically coupled to vertical supports areas of formwork elements up or in the longitudinal direction of the carrier directed force components which then according to the prior art can lead to an unwanted and often dangerous lifting of the formwork elements of the vertical supports or to an unintentional displacement of the formwork elements relative to the vertical supports.
- the lift-off is designed as a first hook element, which is fixed, but possibly releasably connected to the vertical support and engages in the mounted position of a formwork element in a second hook element, which is formed on the carrier of the respective shuttering element.
- the anti-lifting device according to the invention can be produced economically and efficiently, wherein it is also achieved that the effect of the anti-lift device can be achieved solely by hooking the first and second hook elements, without having to handle them separately. Bende parts or tools would be necessary. This has a corresponding effect on the disassembly of the slab formwork system according to the invention positively.
- the carriers of the formwork elements may have an at least partially C-shaped cross-section, which has two legs extending away from a base portion, wherein one of these two legs is designed as a second hook element. Since this second leg is present in any case with a C-shaped support, the second hook element can be realized in this case, practically without any economic effort.
- the designed as a second hook member legs of the carrier may further at least partially form a support surface for supporting the carrier on a head of a vertical support, so that this leg then plays a dual role, which further increases the efficiency of the overall arrangement.
- the head of a vertical support may have in each case a recess of said support surface engaging fixing elements, wherein the recess is provided on the said base portion of the C-shaped support facing away from the end of the support surface. It is particularly advantageous in this case if the first hook elements are formed on the fixing elements attached to the head of the vertical support.
- the carrier can be coupled to the vertical support optionally in two mutually offset by 90 ° directions.
- the recess for fixing the carrier in its longitudinal direction relative to the vertical support erf ⁇ ndungsloom not in the base portion, but rather provided in the support surface and there in the base portion remote area it is possible to arrange a plurality of fixing such on the head of a vertical support, that a carrier in two mutually offset by 90 ° directions at the head of the vertical support can be attached.
- the variability of a slab formwork system according to the invention over known slab formwork systems is increased in such a way that the ceiling formwork system can be optimally adapted to individual circumstances by the given choice when attaching formwork elements to a head of a vertical support.
- one leg of the carrier serves as a support surface and as a second hook element for cooperation with a vertical support
- the other leg of the carrier may be formed as a contact surface for a plurality of longitudinal members of a grate element, then ultimately a formwork skin can be applied.
- the other limb can also be formed as a contact surface for a formwork panel, in which case, in contrast to the use of a grate element, there are no further elements between the support according to the invention and the scarf panel.
- the carriers used according to the invention are preferably designed as open profile elements. Alternatively, however, closed profiles can be used, in which then the described recess is also provided in the region of the respective support surface, which is brought into contact with the vertical supports. It is preferred if the support surface of the carrier in each of the two mutually remote end portions of the carrier in each case two, three or more recesses. This plurality of recesses makes it possible to couple a carrier at different, distributed over its length positions with a vertical support, so that again different installation situations can be taken into account, but at the same time at each selected position, the Abhebomme invention is realized.
- the carrier can then be mounted on a vertical support via said concurrent engagement either flush with its head, or it can be mounted such that the support projects beyond the head of the vertical support on both sides.
- the carrier can project beyond the head of the vertical support over different lengths adapted to the respective conditions. These different lengths are easily adjustable by selecting a suitable pair of recesses.
- a carrier provided with said tab can be positioned above a head of a vertical support such that the recess in the tab is located directly above the respective fixing element of the head, whereupon the support can be lowered onto the head, where the Fixing element of the head in the recess of the tab "threaded" is.
- the tab in each of the two mutually remote end portions of a carrier has two, three or more recesses of the type mentioned, which are each aligned with corresponding recesses in the support surface.
- a corresponding recess in the tab are provided for each recess in the support surface, so that the insertion of the fixing element is facilitated in any recesses of the support surface.
- the underside of the support surface extends in its mounted position, starting from the base portion obliquely upwards, so that in particular the angle between the underside of the support surface and the base portion is smaller than 90 ° and preferably between 70 ° and 80 °.
- the vertical supports may each be provided with a support head, which in addition to a perpendicular to the longitudinal extent of the respective vertical support extending support plane thereof angled fixing tabs for engagement in a respective recess of the support surface of a support.
- the above-described fixing elements of the support head are then formed on the fixing straps.
- angled Fixierlaschen is advantageous in that for the support head a plate-shaped element in the raw state can be bent from the certain areas, preferably corner areas as Fixierla- see, so that it is not necessary to attach separate fixing on the support head ,
- eight fixing lugs can be provided per support head, which extend in particular perpendicular to the support plane of the support head.
- the support plane is formed substantially square or rectangular, in which case they may each have two adjacent fixing lugs in each of its four corner regions, each of which is perpendicular to each other.
- fixing elements are formed on only a few of the plurality of fixing straps, which at the same time have first hook elements. This means that only when coupling formwork elements with such fixing straps, the fixing elements are designed as first hook elements, the anti-lifting device according to the invention is realized. However, if such fixing lugs are used for the preparation of a connection between formwork element and vertical support, the fixing elements are not designed as a first hook elements, is deliberately dispensed with the anti-lifting device according to the invention. This may well be useful and advantageous in certain applications, for example, if it is necessary due to the existing installation situation, hang a formwork element from above on the associated vertical supports, since in this case the first hook elements would collide with the second hook elements.
- the omission of the first hook elements makes such vertical laying from above possible. Furthermore, it is necessary in certain applications, prestreschalen a slab formwork at a certain point in the interior targeted to create in this way, for example, a walk-through. In such a case, the Stanfordschalende formwork element must be lifted vertically upwards be, which would not be possible in Buffalo of first hook elements in the field of vertical supports.
- fixing lugs of a support head which extend in a first direction have fixing elements with first hook elements and fixing lugs of the same support head which extend in a second direction perpendicular to the first direction have fixing elements, which are free of first hook elements. Then, when formwork elements are coupled with such a support head, which extend perpendicular to the first direction, a lift-off is provided. However, if the shuttering elements extend perpendicular to the second direction, a lift-off protection is deliberately omitted.
- the support head has abutment areas for the rear side of the base section of a carrier facing away from the legs, wherein the abutment surfaces of the abutment areas extend in particular perpendicularly to the support plane.
- areas of the fixing elements or fixing lugs are located in the recesses of the support surface complementary thereto, whereby the rear side of the base section is simultaneously supported on said abutment areas or only a short distance therefrom Stop areas comes to rest.
- these stop regions prevent the fixing elements from the recesses can move out, so that here a reliable and defined fixation of a carrier is secured to a support head.
- a total of eight stop areas are provided, the stop surfaces extend in particular at an angle of 90 ° to their respective associated fixing tabs.
- These eight stop regions make it possible for one carrier each to be fastened to the support head at four different positions, two orientations of the carrier in a horizontal plane offset by 90 ° being possible at each of these four positions. Overall, therefore, four different carriers can be arranged on a support head at the same time, the orientation of each individual carrier can be selected individually.
- the abovementioned stop areas of the support head can be formed by separate stop elements, which are subsequently coupled to the support head. However, it is preferred if four abutment regions are formed by a section of the support head or of the plate-shaped element, from which the support head is manufactured, which is bent in a substantially U-shaped manner and extends upwards from the support plane. Each two further stop areas can be formed by one stop tab each bent out of the support plane upwards. In this way, the use of separate elements can be completely avoided, and it is also possible to manufacture the entire support head from a single plate-shaped element.
- the support head used according to the invention can be connected either detachably or fixedly to its associated vertical support. It is particularly advantageous if the support head can be coupled to a preferably substantially square head plate of a commercially available vertical support, wherein the sizes of head plate and support head can be approximately equal in plan view to each other. In this case, the support head can be pushed onto the head plate in a direction running parallel to the head plate of the vertical support. The underside of a support plane of the support head comes to lie in the mounted position preferably directly on the top plate of the vertical support, so that no vertical extension of the support over its top plate extending elements are needed. The distance between the top of the top plate of the vertical support and the support plane of the support head thus corresponds in this advantageous embodiment substantially the thickness of the material used for the support head.
- all support heads, vertical supports, and / or end regions of the carriers used are designed to be identical to one another. This then allows any combination variants and avoids the erroneous handling of individual components of the slab formwork system according to the invention.
- the installation of a slab formwork system according to the invention is particularly convenient to perform for a fitter when the vertical support and the support of a formwork element are hooked together in such a position in which include the formwork element and the vertical support an angle less than 90 °.
- the formwork element runs essentially parallel to the respective vertical support or the respective vertical supports.
- the formwork elements used in accordance with the invention may, for example, consist of longitudinal members spaced parallel to one another and fixedly connected to at least one cross member extending perpendicular thereto, the upper sides of the side members forming a contact surface for a formwork skin, the top side of the cross member (s) (FIG. s) bears against the underside of the side members, and the underside of the cross member (s) forms a support surface of the type described.
- form the shuttering elements according to the invention grate elements, which are first mounted on the vertical supports, whereupon then the formwork skin or the formwork panels can be applied to the grate elements.
- formwork elements in such a way that a formwork skin is applied directly to the above-described supports, in particular on their upper sides.

- Fig. 8 is a view according to FIG. 7, in which all four carriers are parallel to each other.
- the carrier 2 shown in FIG. 1 is formed as an open elongated profile element which has a C-shaped section with two legs extending away from a base section 4, the lower leg serving as a support surface 6 for resting on a head of a vertical support is designed.
- the upper, supported for reinforcement with a diagonal strut 7 on the base portion 4 leg forms a support surface 8 for the undersides of longitudinal members, for example, perpendicular to the carrier 2, which in this case then forms a cross member extend, so that said Side members together with the carrier 2 and optionally further cross members form a grate element, on which a formwork skin can be applied.
- the support surface 8 can also serve directly as a support surface for a formlining.
- the base portion 4 In the illustrated carrier 2 is - seen in cross section - the base portion 4 longer than the support surface 8, which in turn is designed to be longer than the support surface 6.
- the length of the support surface 8 is approximately twice the length of the support surface 6, whereas the length of the support surface 8
- Base portion 4 is approximately twice the length of the support surface 8.
- the underside of the support surface 6 is not parallel to the support surface 8, but rather obliquely upwards in the direction of the support surface 8. In this way it follows that the thickness of the support surface 6 with increasing distance from the base portion 4 is lower, as is the support - Flat 8 facing top of the support surface 6, in contrast to its underside parallel to the support surface 8 extends.
- an upwardly angled tab 10 is formed, which extends parallel to the base portion 4 in the direction of the support surface 8.
- a round transition could also be formed between the support surface 6 and the tab 10, so that, for example, the shape of a quadrant is set substantially in cross section between the support surface 6 and the tab 10.
- the tab 10 is provided in the illustrated embodiment with two spaced apart in the longitudinal direction of the carrier 2 V-shaped recesses 12, 14, wherein the width of these recesses 12, 14 decreases each with increasing distance from the support surface.
- the recesses 12, 14 extend over the entire height of the tab 10 and go in its lower end in recesses 20, 22 of the support surface 6 via.
- the width of the recesses 20, 22 corresponds approximately to the width of the V-shaped recesses 12, 14 in their recesses 20, 22 facing end region.
- the recesses 20, 22 extend into the support surface 6 by less than half the length of the support surface 6.
- Fig. 1 only one end portion of the carrier 2 is shown.
- the other, not shown, end portion of the carrier 2 is formed analogous to the illustrated end region, so that the carrier 2 has two recesses 12, 14 and two recesses 20, 22 in each of its two end regions.
- Fig. 2 shows in three-dimensional view a head 28 which can be coupled to a vertical support (not shown).
- the head 28 is made of an originally substantially rectangular steel plate, which is bent such that in its central region a substantially U-shaped bent portion 30 is formed, which extends over the entire width of the head 28 upwards and which has in its upper portion on both sides depending on an outwardly projecting stop bead 31.
- the U-shaped section 30 divides the plane formed as a support plane 32 base of the head 28 into two halves of equal size.
- said support plane 32 absorbs the vertical forces to be transmitted by the supports 2 to a vertical support, since the support surface 6 of a support 2 is ultimately supported on the support plane 32 of the head 28, which will be explained below.
- the support plane 32 has at each of its two end regions facing away from each other a U-shaped section.
- shaped downwardly curved coupling tab 34 so that between the mutually facing coupling tabs 34 a parallel to the support plane 32 extending receiving plane for a (not shown) top plate of a vertical support is defined.
- Such a top plate can be inserted in the longitudinal direction of the U-shaped portion 30 in the coupling tabs 34 until it abuts two stop members 36 which are integrally formed with the U-shaped portion and extending from this down into said receiving plane for the Head plate of the vertical support extend. In Figure 1, only one of these stop elements 36 can be seen.
- a spring element is attached in the cavity surrounded by the U-shaped portion 30, a spring element is attached.
- the end portions 40 of the spring element 38 are in the region of an opening 42 of the U-shaped portion 30 and bent in the region of an end face of the U-shaped portion 30 such that the spring element 38 is held captive on the head 28.
- the spring element 38 is shaped in such a way that a middle section thereof extends downwards at least into the receiving plane provided for the head plate of a vertical support, between the coupling lugs 34, so that said section of the spring element 38 enters a frontal cavity of a vertical support or a head plate of a vertical support can snap, whereby the head 28 can be fixed in a defined position to a vertical support.
- the two stop members 36 abut an edge of the head plate of a vertical support.
- the spring element is deformed by the withdrawal force, so that the spring element ensures a correct positioning of the head 28 relative to the vertical support on the one hand, but also allows a subsequent release of the head 28 from a vertical support.
- the four corner regions of the support plane 32 are each bent upwards perpendicular to the support plane 32, so that they form a total of eight fixing lugs 44 - 51, which each extend either perpendicular or parallel to the longitudinal direction of the U-shaped section 30.
- Two mutually perpendicular, mutually adjacent fixing tabs 51, 44; 45, 46; 47, 48; 49, 50 are each associated with a corner of the support plane 32.
- the width of the fixing lugs 44 to 51 is slightly more than twice their height, wherein the corners of the support plane 32 respectively facing end portions of the fixing lugs 44 to 51 are chamfered.
- a carrier 2 is coupled via one of the fixing straps 44 to 51, only one of the two fixing elements 52 to 66 of a fixing strap 44 to 51 is always effective.
- the provision of two fixing elements 52 to 66 per fixing lug pair 51, 44; 45, 46; 47, 48; 49, 50 makes it possible to couple a carrier 2 optionally in two mutually offset by 90 °, parallel to the support plane 32 extending directions with a fixing tab 44 to 51.
- a stop tab 68, 70 bent out upwards, each of the two end, perpendicular to the support plane 32 extending edges of the Antschla see 68, 70 each have a stop surface 72, 74, 76, 78 for form the back of the base portion 4 of a carrier 2.
- abutment surfaces 80, 82, 84, 86 are formed by regions of the U-shaped section 30 extending perpendicular to the support plane 32, in particular by its abutment beads 31. These stop Areas 80 to 86 are each adapted to cooperate with the back of the base portion 4 of a carrier 2.
- a carrier 2 can be fixed between the following pairs of mutually opposite fixing elements 52 to 66 and stop surfaces 72 to 86: 52, 80; 54, 72; 56, 74; 58, 82; 60, 84; 62, 76; 64, 78; 66, 86.
- all those fixing lugs 46, 47, 50, 51 which extend perpendicularly to the longitudinal direction of the U-shaped section 30 have at their fixing elements 58, 60, 66, 52 respectively a first hook element 87, which in each case projects onto the U-shaped portion 30 extends and forms an undercut when viewed from above, which can be engaged behind by a second hook element or a support surface 6 of a carrier 2.
- the other fixing elements 54, 56, 62, 64 of the remaining fixing straps are free of first hook elements 87.
- first hook elements 87 a parallel to the longitudinal direction of the U-shaped portion 30 extending, coupled to the head 28 carrier 2 ge by first hook elements 87 - A lifting is secured by the head 28, whereas a perpendicular to the longitudinal direction of the U-shaped portion 30 extending, coupled to the head 28 carrier 2 due to the lack of the fixing elements 54, 56, 62, 64 first hook elements 87 vertically from the head 28 can be lifted upwards.
- FIG. 3 and 4 show a head plate 88 of a vertical support 90, which is so far inserted into coupling lugs 34 of a head 28 until an edge of the top plate 88 abuts against the stop elements 36 of the head 28.
- a support 2 according to FIG. 1 is coupled to the head 28, to the support surface 8 of which side members 92 are fastened, which are lowered. extend right to the carrier 2.
- a formwork skin 94 is attached to the top of the longitudinal beam 92, which in turn is coupled to a Stirnabschalung 96.
- the carrier 2 is coupled to the head 28 such that the fixing element 52 extends into the recess 12 and the recess 20 (FIG. 1).
- the fixing element 58 extends into the recess 14 and the recess 22 (FIG. 1).
- the base portion 4 of the carrier 2 is supported on its rear side on the abutment surfaces 80 and 82, so that ultimately these stop surfaces 80, 82 together with the fixing elements 52, 58 effectively prevent the carrier 2 move perpendicular to its base portion 4 can.
- the engagement between the fixing elements 52, 58 and the recesses 20, 22 ensures that no movement in the longitudinal direction of the carrier 2 relative to the head 28 can take place.
- the carrier 2 could also be coupled in a position offset in the longitudinal direction of the carrier 2 with the head 28, in which only the fixing element 58 would engage in the recess 12 or in the recess 20 corresponding thereto.
- the support 2 would then no longer extend as shown in FIGS. 3 and 4 over the entire support plane 32 of the head 28 away. Rather, it would only extend over less than half the width of the support plane 32, so that, for example, via the fixing element 52, a further carrier 2 could be coupled to the head 28 so that both carriers 2 would extend aligned in the longitudinal direction ,
- a support 2 could also be coupled to the head 28 via its recesses 12, 14 or recesses 20, 22 that it extends perpendicular to its orientation shown in Fig. 3.
- the fixing element 54 would engage in one of the recesses 20, 22, wherein the back of the base portion 4 of the carrier would be supported on the stop surface 72 of the stop tab 68.
- each of the carriers 2 can then be fixed between one of the above-mentioned pairs of fixing elements 52 to 66 and stop surfaces 72 to 86.
- the individual carriers 2 may extend parallel or perpendicular to each other.
- FIGS. 5a to c show how a coupling between carrier 2 and head 28, as shown in FIG. 3, can be produced.
- a formwork element 98 consisting of girders 2 and longitudinal girders 92 is aligned relative to a vertical girder 90 such that the longitudinal girders 92 extend either substantially parallel to the vertical support 90 or, as shown in FIG. 5a, somewhat obliquely to this orientation.
- a formwork element 98 can be easily grasped by a fitter and lifted so that the support 2 is ultimately located above a head 28 of the vertical support 90.
- the formwork element 98 is aligned and lowered by the fitter so that the fixing elements 52, 58 are inserted into the V-shaped recesses 12, 14 of the tab 10. This insertion is facilitated by the V-shape of the recesses 12, 14.
- the first hook elements 87 of the fixing elements 52, 58 are only so far in the direction of the U-shaped portion 30, that said insertion is not hindered. In this way, so between the head 28 and the carrier 2 already a hook connection made in which the weight of the shuttering element 98 can be introduced into the vertical support 90 for the greater part on the support plane 32, so that the person performing the assembly no longer has to hold the full weight of Schalungsele- element 98.
- the formwork element 98 according to FIG. 5 b is then pivoted upwards in the direction of the arrow about a pivot axis extending parallel to the longitudinal axis of the carrier 2, wherein the fixing elements 52, 58 - guided by the V - shaped recesses 12, 14 - are moved into the recesses 20, 22 of the support surface 6 of the carrier 2. Said pivoting movement is continued until the position according to FIG. 5 c is reached, in which the formwork element 98 or its side members 92 extend in a horizontal direction perpendicular to the vertical support 90. It can be seen particularly clearly from FIG.
- stop surfaces 80, 82 effectively prevent the carrier 2 in the arrowed direction from moving perpendicularly to the base section 4 of the carrier 2 in this completely mounted position such that the fixing elements 52, 58 are disengaged with the recesses 20, 22 arrive.
- FIG. 5c shows that the first hook elements 87 were brought into a position solely by said pivoting movement, in which they engage over the recess-free region of the support surface or of the second hook elements 6, so that the formwork element 98 is not perpendicularly upwards parallel to the base section 4 can be raised.
- a release of the head 28 and formwork element 98 is therefore only possible if the formwork element 98 is pivoted against the direction of the arrow of Fig. 5b down. If, as part of the dismantling of the formwork element 98 in the reverse order as described in connection with Fig.
- the formed on the underside of the support surface 6 bevel, which forms an angle of about 75 ° with the base portion 4, is advantageous to the effect. Because of this slope, it is namely possible to swing the formwork element 98, starting from the position according to FIG. 5c, counter to the direction of the arrow in FIG. 5b without a clamping effect occurring between the upper side of the formwork element 98, a formwork skin resting thereon and an already created concrete surface. Rather, the slope ensures that move all parts of the formwork element 98 when pivoting down, so that a trouble stripping is possible.
- FIGS. 6a-c illustrate that a corresponding coupling process can be realized if it is ultimately desired that the finished assembled formwork element 98 without realizing a lift-off in an offset from FIGS. 3 and 5a to c by 90 ° angle should extend relative to the head 28.
- the fixing element 64 then interacts with the recess 12 or the recess 20 of the carrier 2.
- the described pivoting process according to FIGS. 6a to 6c is analogous to the pivoting process described in connection with FIGS. 5a to c with the difference that the rear side of the base section 4 of the carrier 2 according to FIG. 6c ultimately abuts the support surface 78 of the stop tab 70, which in turn prevents that the fixing element 64 can move out of the recess 20 or 22 out.
- FIG. 7 shows a total of four carriers 100, 102, 104, 106, which are coupled to a head 28 of a vertical support 90.
