Definitions
- the invention relates to a support device for a ceiling support for supporting a ceiling formwork panel.
- the invention also relates to a ceiling support according to claim 11 and a ceiling formwork system according to claim 13.
- the invention also relates to a method for stripping a ceiling formwork panel, which is supported by at least one ceiling prop, according to claim 14.
- Ceiling formwork systems for producing ceilings, in particular for concreting concrete ceilings are known in various designs from the prior art.
- Known ceiling formwork systems can, for example, have a system of steel or wooden beams on which formwork panels that form the underside of the concrete ceiling are placed.
- the formwork panels can also be attached to a rigid substructure, usually made of steel or aluminum beams.
- a substructure with a formwork panel attached thereto is generally referred to as a panel or as a ceiling formwork panel.
- the slab formwork panels can also be made of a polymer.
- the ceiling formwork panel is usually supported by means of support elements, in particular ceiling props.
- ceiling supports are often telescopic so that the ceiling support can be adjusted to different heights.
- Extensions are also known from the prior art, which can be mounted on an upper end of the ceiling support, usually on an adapter slat located there.
- So-called support heads are formed or mounted at the upper end of the ceiling support or at the upper end of the extension of the ceiling support.
- the support heads can be integral with the ceiling support or an extension of the ceiling support, but it is usually provided that the support heads are detachably mounted.
- the prop heads extend the slab props axially in the direction of the concrete slab to be created.
- the support heads are designed in such a way that they act on the ceiling formwork panels, preferably can hook into suitable structures that are present there, as a result of which such ceiling formwork systems can be set up quickly.
- the slab formwork system formed by the slab formwork panels and the slab props is under load.
- this load means that the ceiling formwork panels can only be loosened with difficulty.
- a spindle device which the ceiling supports typically have, can be used to lower the ceiling supports and thus to lower the support head.
- a method for stripping a ceiling formwork panel is known, for which reference is made in particular to the description of FIGS. 1a to 1f.
- a support head with lowerable support height for a ceiling support is also known.
- support heads which can be pivoted according to the desired inclination of the concrete slab and can be fixed in the pivoted position.
- support heads which can be pivoted according to the desired inclination of the concrete slab and can be fixed in the pivoted position.
- ceiling formwork panels in particular large-panel ceiling formwork
- the ceiling formwork panels can be swiveled upwards from a safe position from a lower level. After swiveling up, the ceiling formwork panel is then supported by a ceiling prop with a suitable support head.
- a side edge of the ceiling formwork panel to be swiveled up is hooked onto a ceiling support that has already been erected.
- the ceiling formwork panel can then be swiveled up with a formwork aid, which is generally a telescopic rod.
- the formwork for the slab formwork panels is stripped downwards, since stripping upwards is not possible due to the concrete slab.
- the ceiling supports In order for the formwork to be removed from the ceiling formwork panels, the ceiling supports must first be lowered at least along one side edge of the ceiling formwork panels to such an extent that they no longer engage in the ceiling formwork panels.
- a problem when stripping ceiling formwork panels is that when the ceiling formwork panels are pivoted away or pivoted down, the supporting heads of the ceiling props, which were previously lowered, are in the pivoting path. This makes it difficult to simply and safely dismantle the slab formwork panels.
- the prop heads are usually lowered by the spindle mechanism of the floor props.
- the spindle travel is limited and is generally not sufficient to completely remove the support head from the pivoting path of the ceiling formwork panels.
- unscrewing is such that the support head is no longer in the pivoting path of the ceiling formwork panels, strenuous and time-consuming.
- the present invention is therefore based on the object of creating a support device for a ceiling prop for supporting a ceiling formwork panel, which allows simple and safe stripping or simple and safe dismantling of the ceiling formwork panel.
- the present invention is also based on the object of creating a ceiling prop that enables a simple and safe stripping or a simple and quick dismantling of a ceiling formwork panel.
- the invention is also based on the object of creating a ceiling formwork system which enables simple and safe stripping or simple and safe dismantling of a ceiling formwork panel.
- the present invention is based on the object of providing a method for stripping a ceiling formwork panel, with which the ceiling formwork panel can be easily and safely stripped or dismantled.
- the support device according to the invention for a ceiling prop for supporting a ceiling formwork panel has at least one upper elongate support element and one lower elongate support element.
- the support elements are pivotally connected to one another, the support elements being able to be brought into a working position in which the support elements are preferably aligned coaxially with one another, and the support elements being pivotable into a tilted position in which the support elements are tilted by a tilting angle with respect to one another.
- a locking element is provided, which secures the support elements against pivoting in the working position, with the locking element bridging a connecting region between the two supporting elements in the working position.
- the locking element can be brought into a release position in which the locking element is arranged outside of the connection area.
- the ceiling support can in particular be a scaffolding post or a vertical post.
- the ceiling support can also have a scaffolding post or a vertical post as a component.
- a support device for a ceiling prop is designed in such a way that it has at least one upper elongated support element and one lower elongated support element which are pivotably connected to one another.
- This makes it possible to align the support device in a working position in such a way that it can absorb the weight forces that arise when creating a concrete slab, in particular when concreting a concrete slab, in the usual way.
- the support elements are preferably aligned parallel, in particular coaxially, to one another in the working position, so that the forces that occur can be advantageously transmitted.
- the support elements are generally aligned in such a way that they run coaxially to the longitudinal axis of the ceiling support.
- the supporting elements are aligned orthogonally to the underside of the ceiling to be produced and are therefore also aligned orthogonally to the underside of the ceiling formwork panels. If a sloping ceiling is to be produced, it can preferably be provided that the support elements are not aligned orthogonally to the ceiling to be produced or the underside of the ceiling formwork panels, but run at an angle to the orthogonal. However, the support elements are preferably aligned coaxially with the ceiling support, which is preferably placed orthogonally on a plane which is located below the ceiling to be constructed.
- the support elements are connected to one another in such a way that the support elements can be pivoted into a tilted position.
- the upper elongate support element is swung out. This makes it possible to pivot a support head, which is connected to the upper elongate support element, in such a way that the support head is no longer in the pivoting path of the ceiling formwork panels when they are pivoted downwards for the purpose of stripping.
- the elongate support elements are secured against pivoting in the working position.
- a locking element is provided according to the invention, which secures the support elements against pivoting.
- the locking element bridges a connecting area between the two support elements in the working position. This reliably prevents the support elements from pivoting unintentionally into the tilted position. Furthermore, the stability of the two support elements in the working position is supported by bridging the connection area.
- Bringing the supporting elements into a tilted position in particular by tilting the upper supporting element by a tilting angle relative to the lower supporting element, can be achieved in a simple manner according to the invention by arranging the locking element outside of the connection region, preferably by displacing it accordingly.
- the result of this is that the locking element no longer covers the connection area, as a result of which the two support elements can be pivoted relative to one another, for example using a corresponding joint.
- connection area is to be understood within the scope of the invention in particular that the locking element does not prevent pivoting of the support elements relative to one another or that the locking element does not intersect a plane of the connection area.
- the locking element is preferably displaced in such a way that it is located above the connection area and preferably extends no further downwards than the upper support element. This solution has the advantage that the locking element does not move independently into the release position.
- the locking element is located below the connection area in the released position, preferably in such a way that the locking element does not extend further upwards in the direction of the connection area, like the lower support element.
- the locking element performs a movement that runs parallel to the longitudinal axis of the upper support element and/or the longitudinal axis of the lower support element, with the longitudinal axes of the support elements preferably being aligned coaxially with one another in the working position.
- the locking element In order to bring the locking element into a release position, it is also conceivable for the locking element to be constructed in two parts, with a first locking part being pushed upwards and a second locking part being pushed downwards in order to arrange the locking element as a whole outside of the connection area. In this solution it can be provided in the working position that the first locking part locks with the second locking part.
- the support device is designed to be pivotable or pivotable away, it is possible to pivot the ceiling formwork panels away without colliding.
- the support device according to the invention also simplifies shuttering or assembly of the ceiling formwork panels from below by prior pivoting away of the support device or the upper elongated support element. This means that shuttering from below can be carried out effectively, efficiently and safely.
- the shuttering and shuttering of the slab formwork panels can thus be carried out from a safe position from below.
- the locking element extends from a lower end area of the upper support element to an upper end area of the lower support element and thereby bridges the connection area.
- connection area can be bridged in a particularly advantageous manner, which prevents the upper support element from being accidentally pivoted out of the working position and also the support elements in the Working position can be additionally stabilized.
- the locking element rests at least in sections on an inner wall and/or an outer wall of the support elements in the working position.
- the locking element is in close contact with the inner wall and/or the outer wall of the support element.
- the support elements are particularly advantageously stabilized.
- the locking element can be designed in one embodiment in such a way that it surrounds the two support elements on the outside or rests against the outer walls of the support elements.
- the locking element can, for example, be rod-shaped or plate-shaped and can surround the support elements on the outside.
- the locking element can have one or more locking members, for example several rod- or plate-shaped members. If necessary, the locking members can also be connected to one another, for example in order to form a cage which encloses the support elements on the outside. In a particularly advantageous embodiment, which is explained in more detail below, it can be provided that the locking element is tubular or sleeve-shaped, for example as a support sleeve or sliding sleeve.
- the locking element bears against an inner wall of the support elements.
- the support elements can be tubular, for example.
- the locking element can be arranged within the tubular support elements.
- one or both support elements have a slot through which an operating part, which is connected to the locking element arranged inside the tubular support elements, protrudes in order to move the locking element along the longitudinal axes of the support elements, in particular upwards and downwards , to move.
- the locking element forms a guide with the support elements in order to move the locking element between the working position and the release position in a guided manner.
- the locking element and the support elements are designed in such a way that they form a guide in order to be able to move the locking element in a guided and defined manner from the working position into the release position.
- This can be a rail guide or a linear guide, for example.
- other configurations, in particular form-fitting configurations, are also possible, which enable a defined displacement of the locking element, preferably along the longitudinal axes of the support elements, in particular coaxially, from the working position into the release position.
- the outer diameters of the support elements are essentially identical, preferably identical, at least in the end areas adjoining the connection area.
- the support elements have an identical outer diameter or an identically designed outer circumference. It is particularly advantageous if the Supporting elements have an identical outer diameter at least in the end regions in which they adjoin the connection region, ie the upper end region of the lower supporting element and the lower end region of the upper supporting element.
- the loads can thus be advantageously absorbed and the locking element can also be moved particularly advantageously, in particular if this is designed in such a way that the locking element bears against the outer walls of the support elements, preferably circumferentially.
- the support elements it is also possible for the support elements to have different outer diameters. Provision can be made here, for example, for the lower support element to have a larger outside diameter than the upper support element.
- the locking element encloses the support elements on the outside, it can be provided that the locking element is designed as a sleeve which has two different outer diameters, so that in the working position the sleeve sits on the shoulder of the lower support element formed by the increase in diameter and after can be displaced up in the direction of the upper support member in the release position.
- the outside diameter of the connecting area is the same as or smaller than the outside diameter of the lower end area of the upper support element and/or the upper end area of the lower support element.
- connection area is the same size as or smaller than the outer diameter of one of the support elements or preferably both support elements, the locking element can be brought into the working position in a particularly simple manner in such a way that the locking element closes the connection area between the two support elements bridged or covered.
- the lower support element is a lower support tube and/or the upper support element is an upper support tube.
- the support elements are designed as support tubes, that is to say tubular.
- the lower support element is thus preferably designed as a lower support tube and the upper support element as an upper support tube.
- the locking element provided according to the invention can be used in a particularly advantageous manner with support tubes, both in such a way that the locking element bears against an inner wall of the support tubes—at least in sections—and in such a way that the locking element bears on an outer wall of the support tubes—at least in sections , to secure the support tubes against unintentional swiveling in the working position.
- the locking element is a displaceable support sleeve.
- a design of the locking element as a displaceable support sleeve has proven to be particularly suitable.
- a support sleeve can be designed in a simple manner in such a way that it bridges the connection area in the working position and can be displaced from there into a release position.
- the support sleeve can also be designed in a simple manner in such a way that at least sections of it bear against the outer walls of the end regions of the support elements in order to stabilize the support tubes in relation to one another in the working position.
- the formation of a guide between the locking element and the support elements in order to move the locking element between the working position and the release position is also possible in a simple manner.
- the use of a support sleeve is particularly advantageous if the support elements are support tubes.
- the support sleeve is preferably designed as a sliding sleeve.
- the support sleeve in the working position encompasses the lower end area of the upper support tube and the upper end area of the lower support tube at least in sections on the outside, preferably fitting snugly.
- a design of the support sleeve such that it encompasses the lower end area of the upper support tube and the upper end area of the lower support tube at least in sections on the outside has proven to be particularly suitable.
- the inner wall of the support sleeve preferably rests closely against the outer walls of the support tubes, so that these are stabilized, particularly in the working position.
- the support sleeve is displaceable coaxially with respect to the upper support tube and/or the lower support tube in order to bring the support sleeve into the release position.
- the support sleeve and the support tubes are designed in such a way that the support sleeve can be moved or brought from the working position to the release position by a movement that runs coaxially to the support tubes, i.e. along the longitudinal axes of the support tubes is. Such a movement can also be carried out particularly easily for the user.
- the lower support tube has a stop, preferably a stop ring, on which a lower front end of the support sleeve rests in the working position.
- a stop in particular a stop ring or at least a partially ring-shaped stop segment, which runs completely around the lower support tube on the outside, has proven to be particularly suitable for reliably defining the position that the support sleeve should assume in the working position.
- the stop can also advantageously be designed as a partially ring-shaped stop segment, particularly if the lower support tube has a cross section that deviates from the circular shape, it also being possible for several stop segments to be provided.
- the support sleeve has an operating element, for example a projection, an overhang or preferably an operating ring, which runs around the support sleeve on the outside, preferably in the shape of a ring or part of a ring, so that an operator can operate the support sleeve particularly easily, in particular coaxially from the working position can move to the release position.
- an operating element for example a projection, an overhang or preferably an operating ring, which runs around the support sleeve on the outside, preferably in the shape of a ring or part of a ring, so that an operator can operate the support sleeve particularly easily, in particular coaxially from the working position can move to the release position.
- the tilting angle between the upper support element and the lower support element in the tilted position is 5 to 90 degrees, preferably 10 to 80 degrees, more preferably 15 to 70 degrees and particularly preferably 20 to 60 degrees degrees, very particularly preferably 20 to 45 degrees, in particular 30 to 35 degrees, in particular 32.5 degrees.
- the aforementioned values for the tilting angle in particular an angle of 30 to 35 degrees, have proven to be particularly suitable in order to ensure that a support head, which is formed on the upper support tube or can be attached to the upper support tube, is out of the pivoting path of the slab formwork panels can be swung out.
- the support device is designed in such a way that the support tubes can only assume two stable positions, the first position being the working position, which is secured by the locking element, in particular the support sleeve, and the second position being the tilted position.
- the two support tubes are either in the working position or are pivoted out to the maximum and assume the tilted position, with the tilting angle relative to the working position being particularly preferably between 30 and 35 degrees, in particular 32.5 degrees.
- an upper front end of the lower support element has a bevel.
- an upper front end of the lower support element in particular in an embodiment as a support tube, has a bevel, ie an angle cut.
- the bevel or the angle cut makes it possible to bring the upper support element, in particular an upper support tube, from the working position into the tilted position in a particularly simple manner.
- a lower front end of the upper support element can rest in the tilted position on the bevel of the upper front end of the lower support tube. This results in stable positioning of the support tubes in the tilted position.
- the bevel 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 element is provided with a bevel.
- the pivoting movement between the support tubes can be realized, for example, by a rotary joint, a ball joint, a hinge or the like. In a special way, it can also be suitable if the pivoting movement is realized by a slotted guide.
- the support tubes are pivotably connected to one another via a pivot.
- connection of the support tubes via an axis of rotation has proven to be particularly suitable, since a defined movement that is also not susceptible to damage can be implemented in this way.
- one of the support tubes has bores, preferably elongated holes, in order to fix the axis of rotation.
- Fixing the axis of rotation in bores, preferably oblong holes, in a support tube has proven to be particularly suitable for achieving reliable and safe pivoting of the support tubes.
- the formation of the bores as elongated holes makes it possible in an advantageous manner that a lifting movement can also be carried out when the upper support tube is pivoted from the working position into the tilted position. This facilitates the pivoting process.
- the elongated holes enable or support an advantageous pivoting of the upper support tube in relation to the lower support tube. To do this, the upper support tube is moved vertically a little or a small distance along the length of the elongated holes, resulting in a height difference compensation when tilting.
- the slotted holes also prevent forces from being transmitted to the axis of rotation passed through the slotted holes.
- the axis of rotation always has vertical play in the elongated holes.
- the axis of rotation is arranged in the elongated holes in such a way that no forces, in particular no pressure forces, act on it when the support head is in the working position, ie is not pivoted.
- the axis of rotation and the elongated holes are therefore designed in such a way that the axis of rotation in the elongated holes in the working position has vertical play upwards and preferably also downwards. This ensures that the compressive forces are only transmitted from the upper support tube to the lower support tube.
- the axis of rotation is preferably designed as a bolt.
- a connecting element is fixed to one of the support tubes, preferably to an inner wall of the support tube, and the connecting element has one or more bores through which the axis of rotation fixed to the other support tube is guided in such a way that the connecting element the axis of rotation can be pivoted.
- the connecting element can have any suitable shape, preferably such that the connecting element can be fixed to an inner wall of the support tube, preferably such that the connecting element can be fixed to two opposite inner wall sides of the support tube.
- the connecting element and the support tube can have corresponding fastening bores, with the aid of which the connecting element can be connected to the support tube.
- the connecting element can preferably be a profile element, in particular with a design that is essentially rectangular in cross section, wherein the outer contour can optionally be adapted to the curvature of the inner wall of the support tube, for which it can be sufficient if the longitudinal running side edges of the connecting element are flattened or provided with a radius.
- the connecting element can preferably be tubular.
- an outer contour of the connecting element is adapted at least in sections to an inner contour of the upper support element, preferably in such a way that the outer contour bears against the inner contour of the upper support element in at least two sections, preferably in three sections, preferably in such a way that at least 5 % of the outer contour of the connecting element rests against the inner contour of the upper support element.
- the aforementioned configuration has proven to be advantageous in order to realize a secure connection of the connecting element to the upper support element. Provision can be made for the outer contour of the connecting element and the inner contour of the upper support element to be designed in such a way that the connecting element is secured against rotation in the upper support element.
- the connecting element has at least two, preferably exactly two, parallel and spaced apart surfaces, in each of which one of the bores is introduced in such a way that the bores guide the axis of rotation in a defined manner.
- the connecting element can also be designed as a hinge or as a T-profile.
- an outer circumference of the lower support tube and/or an outer circumference of the upper support tube and an inner circumference of the support sleeve have a circular cross-section or a non-circular cross-section, preferably a lemon-shaped cross-section (lemon shape), a rectangular cross-section, a triangular cross-section, a triangular lemon-shaped cross-section, a star-shaped cross-section or a polygonal cross-section.
- a configuration of the lower support tube and the upper support tube as well as the support sleeve in such a way that they have a circular cross section can be achieved in a particularly simple and cost-effective manner.
- the outer circumference of the lower support tube and/or the outer circumference of the upper support tube and the inner circumference of the support sleeve have a cross section that deviates from the circular shape.
- This has the advantage that the support sleeve, the inner circumference of which rests, preferably tightly, against the outer circumference of the support tubes in the working position, can absorb torsional forces, so that the support sleeve largely prevents the support tubes from twisting relative to one another. This in particular avoids the connection provided for pivoting between the two support tubes, in particular a pivot axis, being loaded with forces that could lead to damage.
