Description

[0001] Support coupling adapter for a support assembly Description

[0002] The present invention relates to a support coupling adapter for a support assembly, in particular for a support system that can be used to construct a formwork system.

[0003] DE 10 2018 125 702 A1 discloses a support that can be used to construct a support system, for example, for a ceiling support structure. The support comprises a telescopic support shaft with a lower shaft portion providing a support base and an upper shaft portion inserted into the lower shaft portion and lockable thereon in various relative longitudinal positions in the direction of a longitudinal axis of the support. A holding head designed to support one or more support beams is attached to the end of the upper shaft portion remote from the lower shaft portion. In the region of the end of the lower shaft portion receiving the upper shaft portion, a coupling member in the form of a perforated disc is provided on the lower shaft portion and surrounds the upper shaft portion.Coupling beams installed as horizontal beams or diagonal beams, for example, can be coupled with the coupling elements of the supports provided in a support system in order to increase the structural strength of the support system.

[0004] It is the object of the present invention to provide a support coupling adapter for a support assembly with which an increased strength of a support system constructed therewith can be achieved with increased application variability.

[0005] According to the invention, this object is achieved by a support coupling adapter comprising a support coupling part for coupling to a support of a support assembly and an adapter coupling member on at least one of two sides of the support coupling part opposite one another with respect to a coupling adapter center axis. Such a support coupling adapter constructed according to the invention is characterized in that it provides an assembly that is fundamentally separate from a support intended for interaction with it. This means that such a support coupling adapter can be used in the construction of a support system in conjunction with supports or in areas of the support system in which increased rigidity of the support system is to be achieved.

[0006] Furthermore, since the coupling areas generated at the adapter coupling elements also have a lateral offset to the cooperating supports due to their offset to the coupling adapter center axis, the stiffening effect introduced by the adapter coupling elements of support coupling adapters present in a support system is shifted out of the essentially vertically oriented planes spanned by the supports of this support system, which also contributes to an improved stiffening effect.

[0007] It should be noted that, in the sense of the present invention, a coupling of two components or a coupling effect of a component enables the components to be released from one another without having a destructive effect on the coupled components.

[0008] In a preferred embodiment of the support coupling adapter, an adapter coupling element is provided on each of the two sides of the support coupling part that are opposite each other with respect to the coupling adapter's center axis. This can contribute to further increasing the rigidity of a support system constructed with such support coupling adapters, since several adapter coupling elements are provided on the support coupling adapter, thus making it possible to couple a support assembly constructed with such a support coupling adapter to other support assemblies of a support system in spatial areas separated from one another by the distance between the adapter coupling elements.In order to couple the support coupling adapter to a support cooperating with it, the support coupling part can comprise a coupling housing which is axially open in the direction of the coupling adapter center axis to receive a support head of a support, with a housing base for resting on a support head and a housing wall extending from the housing base and preferably completely surrounding the coupling adapter center axis.

[0009] For an inherently stable structure of the support coupling adapter, it is proposed that each adapter coupling element is connected to the housing base and / or the housing wall.

[0010] In order to be able to introduce a defined distance of the adapter coupling elements to the coupling adapter center axis and thus also to a support cooperating with the support coupling adapter, at least one, preferably each adapter coupling element can be connected to the housing base and / or the housing wall by a coupling element connecting projection, preferably in the form of a tube or bolt.

[0011] For simple and detachable coupling of a holding head of a support assembly to the support coupling adapter or a support cooperating therewith, a housing base access opening can be formed in the housing base.

[0012] In order to maintain a coupling of the support coupling adapter with a cooperating support that is secured against relative rotation, the coupling housing can have a non-rotationally symmetrical, preferably polygonal, inner circumferential contour.

[0013] For a high degree of versatility of use, it is proposed that at least one, preferably each adapter coupling element comprises a perforated disc with a plurality of coupling openings arranged circumferentially around a disc center axis. Such perforated discs are provided, for example, in scaffolding construction on vertical posts in order to stably couple the vertical posts to one another during the erection of a scaffold, for example using horizontal bars and diagonal bars. The use of such perforated discs as adapter coupling elements in the support coupling adapter constructed according to the invention creates the possibility of being able to use components available from scaffolding construction when constructing a support system comprising a plurality of support coupling adapters constructed according to the invention.

[0014] In at least one, preferably each, perforated disc, the disc center axis can be substantially parallel to the coupling adapter center axis, so that a plane spanned by such a perforated disc is substantially orthogonal to a longitudinal axis of a support cooperating with the support coupling adapter. These planes also essentially define the direction of extension of coupling bars used to connect different support coupling adapters.

[0015] In particular, when wedge heads known from scaffolding are used to couple such coupling bars or the like to the adapter coupling elements, increased coupling strength can be ensured if, in at least one, preferably each adapter coupling element, a preferably tubular or bolt-like abutment projection is provided in a central region of the perforated disc, extending from the perforated disc in at least one axial direction, preferably in both axial directions. Such an abutment projection, with its outer peripheral surface, forms an abutment for a wedge head used for coupling, whereby the wedge head is essentially blocked against pivoting or tilting relative to the cooperating perforated disc.

[0016] In order to achieve a symmetrical or evenly distributed stiffening effect in a support system, the support coupling adapter can be designed to be substantially symmetrical with respect to the coupling adapter's center axis. This can, for example, be point symmetry with respect to the coupling adapter's center axis and / or mirror symmetry with respect to a plane containing the coupling adapter's center axis.The present invention further relates to a support assembly, in particular for a support system, comprising: a support elongated in the direction of a support longitudinal axis with a support base to be positioned on a substrate at a first axial end region of a preferably telescopic support shaft and a support head at a second axial end region of the support shaft, a support coupling adapter constructed according to the invention, wherein in the assembled state of the support assembly the support coupling adapter is supported with its support coupling part on the support head.

[0017] In order to be able to achieve a substantially rotationally fixed coupling of the support coupling adapter to the support in cooperation with the coupling part, it is proposed that the support head has a non-rotationally symmetrical, preferably polygonal, outer circumferential contour, so that when the support coupling adapter is supported on the support head, the support head and the coupling housing are in a form-fitting manner with one another in the circumferential direction.

[0018] In order to be able to support, for example, essentially horizontally extending support beams on the support assemblies in a support system constructed with a plurality of support assemblies constructed according to the invention, such a support assembly can have a holding head designed for attachment to the support head of an associated support with the support coupling part of the support coupling adapter being interposed. By interposing the support coupling part between the support head of the support resting on a substructure and the holding part holding one or more support beams of a support system, the support coupling adapter is secured against detachment from the support assembly without the need for additional locking measures.

[0019] For coupling to a support, the holding head can comprise a holding head base and a holding head coupling projection extending from the holding head base, preferably in a tubular or bolt-like manner, wherein, when the support coupling adapter and holding head are attached to the support, the holding head coupling projection extends through the housing base through-opening into a support head through-opening provided on the support head, preferably in such a way that the holding head is rotatable about the support longitudinal axis with respect to the support and / or the support coupling adapter.With such a rotatability of a holding head with respect to the support cooperating with it and also with respect to the associated support coupling adapter, it is fundamentally also possible to integrate support beams resting on the holding heads in a support system into the support system with an extension direction that deviates from the extension direction of vertical planes spanned by the supports of the support system and thus also from the extension direction of coupling bars coupling individual support assemblies to one another.

[0020] For a stable supporting effect for support beams of a support system, the holding head can comprise at least two holding projections extending from the holding head base substantially opposite to the holding head coupling projection.

[0021] The invention further relates to a support system, in particular for a formwork system, comprising a plurality of support assemblies constructed according to the invention and a plurality of support beams carried on the support assemblies, wherein at least two support assemblies are coupled to one another by at least one coupling bar, wherein the at least one coupling bar is coupled in each of its end regions to an adapter coupling member of a support coupling adapter of one of the support assemblies coupled to one another by this coupling bar.

[0022] To achieve a further increased rigidity of the support system, at least one support assembly can be coupled to a plurality of further support assemblies by a plurality of coupling bars.

[0023] Using the support coupling adapter constructed according to the invention, it is also possible to couple at least one auxiliary device, preferably a tread arrangement and / or railing, to adapter coupling elements of at least two support coupling adapters.

[0024] The invention further relates to a formwork system comprising a support system constructed according to the invention and a plurality of formwork elements positioned above the support beams. The formwork elements can, for example, be formwork panels used to construct a concrete slab or precast concrete elements to be integrated into a concrete slab as permanent formwork, or the like.

[0025] The present invention is described in detail below with reference to the accompanying figures. They show:

[0030] Fig. 5 shows a representation corresponding to Fig. 4 of an alternatively constructed support system or formwork system;

[0031] Fig. 6 is a detailed view of the support system of Fig. 5;

[0032] Fig. 7 is an enlarged view of detail VII in Fig. 6.

[0033] A support assembly 10 shown in Figs. 1 and 2 comprises a support 12 constructed, for example, in the manner of a conventional building support, with a support shaft 14. The support shaft 14 is constructed with two shaft parts 16, 18 that are telescopic relative to one another, i.e., lockable in different positions relative to one another in the direction of a support longitudinal axis SL. A plate-like support base 19 is attached to the lower shaft part 16, and a plate-like support head 20 is attached to the upper support part 18. The two support parts 16, 18 are tubular, i.e., hollow components.

[0034] It should be noted that such props 12 designed as construction props differ fundamentally from vertical posts used, for example, in scaffolding construction in that such vertical posts are generally constructed from a single piece of tubing and are positioned one above the other to construct a scaffold and coupled together vertically. The props 12, which are generally telescopically designed with multiple shaft sections to adapt to different installation heights, are generally not intended or designed to be positioned one above the other and coupled together vertically.

[0035] The support assembly 10 further comprises a support coupling adapter 22, also shown in Fig. 3. The support coupling adapter 22 comprises a support coupling part 24 located in a central region thereof, which is essentially constructed with a coupling housing 26. The coupling housing 26 has a housing base 28 and a housing wall 30 adjoining an outer peripheral region of the housing base 28 and extending essentially axially from the housing base 28 in the direction of a coupling adapter center axis KM. Since the housing base 28 has a substantially square outer peripheral contour and the housing wall 38 extends along this substantially square outer peripheral contour of the housing base 28, the coupling housing 26 has a substantially square, i.e., non-rotationally symmetrical, inner peripheral contour.

[0036] In the central region of the housing base 28, a housing base access opening 32 is provided, which, when the housing base 28 rests on the support head 20, is aligned with a support head access opening 34 formed in the support head 20. Since the support head 20 has an outer circumferential contour adapted to the square inner circumferential contour of the coupling housing 26, when the housing base 28 rests on the support head 20, the housing wall 30 surrounding the support head 20 along its outer circumference generates a positive connection between the support coupling adapter 22 and the support 12, essentially preventing a relative rotation of the support coupling adapter 22 with respect to the support 12 about the support longitudinal axis SL.

[0037] The support coupling adapter 22 further comprises an adapter coupling member 36, 38 on each of two sides opposite one another with respect to the coupling adapter center axis KM. Each of the two adapter coupling members 36, 38 is designed as a perforated disc 40, 42 and has a plurality of coupling openings 44, 46 arranged one after the other around a respective disc center axis SMI or SM2.

[0038] It should be noted that such perforated discs 40, 42 are known, for example, from scaffolding construction and are generally provided there on vertical posts in order to be able to couple them with other scaffolding components, for example horizontal bars or diagonal bars, when erecting a scaffold.

[0039] Each of the two perforated discs 40, 42 is firmly connected to the coupling housing 26 by means of a coupling element connecting projection 48, 50, which may be configured, for example, as a tubular, i.e., hollow component, or as a bolt-like, i.e., solid component. For example, the coupling element connecting projections 48, 50 may be firmly connected by welding to the perforated discs 40, 42 on the one hand and to the coupling housing 26 on the other hand in the region of the housing wall 30 and, if necessary, also in the region of the housing base 28.

[0040] In a central area of ​​each perforated disc 40, 42, an abutment projection 52, 54 is provided, preferably extending on both sides in the direction of the respective disc center axis SMI, SM2. These abutment projections 52, 54 can also be tubular, i.e., hollow components, or bolt-like, i.e., solid components. The abutment projections 52, 54, with their respective outer circumferential surfaces, form an abutment for wedge heads to be coupled to the perforated discs 40, 42 in a manner described below, so that these can be coupled to the perforated discs 40, 42 in a defined manner that is essentially secured against pivoting or tilting.

[0041] The support assembly 10 further comprises a holding head 56. The holding head 56 has a holding head base 58, from which a holding head coupling projection 60 extends in a central region. The holding head coupling projection 60 can also be tubular or bolt-like and is dimensioned such that it can be passed through the housing base through-opening 32 of the coupling housing 26 and the support head through-opening 34 of the support head 20 in order to couple the holding head 58 to the support 12 when the housing base 28 rests on the support head 20. This type of coupling of the holding head 56 to the support 12 enables, on the one hand, a rotation of the holding head 56 with respect to the support 12 about the support longitudinal axis SL. On the other hand, the holding head 56 supported on the support 12 ensures that the support coupling adapter 22 is locked to the support 12 and secured against loosening.

[0042] In the illustrated embodiment, the holding head 56 further comprises four holding projections 62, 64, 66, 68 extending from the holding head base 58 opposite the holding head coupling projection 60, for example, designed as angle elements. The holding projections 62, 64, 66, 68 can be used to secure support beams of a support system described below, which rest on the holding head 56 or are supported by it, against falling sideways on the holding head 56 and thus stably couple them to it.

[0043] It can be seen in particular in Fig. 3 that the support coupling adapter 22 is, on the one hand, point-symmetrical with respect to the coupling adapter center axis KM. On the other hand, the support coupling adapter 22 is mirror-symmetrical with respect to a plane spanned by the coupling adapter center axis KM and by a coupling adapter transverse axis KQ corresponding to the extension direction of the coupling element connecting projections 48, 50, as well as with respect to a plane containing the coupling adapter center axis KM and oriented orthogonally to the coupling adapter transverse axis KQ. Fig. 4 shows a support system 70 constructed using a plurality of such support assemblies 10, which can be used, for example, to construct a formwork system generally designated 72. The support system 70 comprises a plurality of support assemblies 10 arranged in respective rows or a rectangular grid.Support beams 74, which can be referred to as longitudinal beams, rest on the support heads 56 of the support assemblies 10. Where two such support beams 74 adjoin one another in a longitudinal direction of the support beams 74, they can each be supported and held on a support head 56 in an overlapping manner.

[0044] Fig. 4 shows that support assemblies 10 with the structure shown in Fig. 1, i.e., with a holding head 56 and a support coupling adapter 22, are used in the support system 70 in those regions in which an end region of a support beam 74 is supported or held in an overlapping manner, possibly with the end region of another support beam 74. In intermediate length regions, the support beams 74 can be supported using, for example, only the supports 12 without using a support coupling adapter 22 or a holding head 56.

[0045] The support assemblies 10 are coupled to one another, on the one hand, by coupling bars 76 extending in the longitudinal direction of the support beams 74, and on the other hand, by coupling bars 78 extending transversely to the support beams 74. With respect to the longitudinal extension direction of the support beams 74, the coupling bars 76 can be referred to as longitudinal coupling bars, and the coupling bars 78 can be referred to as transverse coupling bars. As can be seen more clearly in particular in Figs. 6 and 7, these coupling bars 76 and 78 each have a wedge head 80 in their two end regions, which is generally known from scaffolding construction, with a fastening wedge 82 provided thereon.To couple such a coupling bar 76, 78 to one of the perforated discs 40, 42 of a support coupling adapter 22, the wedge head 80 is pushed from the radial outside over the perforated disc 40, 42 provided for coupling, whereupon the fastening wedge 82 provided on this wedge head 80 is pushed through the coupling opening 44, 46 encompassed by the wedge head 80 and thereby the wedge head 80 is stably locked to the respective perforated disc 40 or 42 with radial support on the respectively associated abutment projection 52, 54.

[0046] By means of the coupling bars 76, 78 which couple the immediately adjacent support assemblies 10 to one another, a stiffening network of coupling bars 76, 78 is generated in the support system 70, which is positioned in a height direction, i.e. generally a vertical direction, beneath the bearing surfaces 82 of the support beams 74. Since, in particular, the coupling bars 76 extending in the longitudinal direction of the support beams 74 are laterally offset, i.e. essentially horizontally, with respect to the associated or adjacent support beams 74, the stiffening effect introduced by these coupling bars 76 takes place outside the vertical planes spanned by the supports 12 coupled thereto. Since, in addition, such a stiffening effect can be achieved on both sides of such a vertical plane by one or moreseveral coupling bars 76 positioned there and these are additionally supported relative to one another via the coupling bars 78 extending transversely thereto, a very stable and rigid structure of the support system 70 is achieved.

[0047] It should be noted that, if necessary, such support assemblies 10 as shown in Fig. 1 can also be used in longitudinal regions of the support beams 74 located between the longitudinal ends of the same, in order to be able to achieve additional networking with coupling bars 78 extending transversely to these in regions located between the longitudinal ends of the support beams 74.

[0048] To construct the formwork system 72 using the support system 70, cross beams 84 can be positioned on the support beams 74 directly held or supported by the support assemblies 10. A plurality of formwork elements 86, designed as formwork panels or the like, can be placed on these cross beams. Alternatively, it is also possible, for example, to use precast concrete parts as such formwork elements, which are then integrated as permanent formwork during the construction of a building ceiling. The support of precast concrete ceilings using such a support system 70 is also possible.

[0049] 5 and 6 show a further design variant for the construction of such a support system 70 or formwork system 72. It can be seen that, for example, the coupling bars 76 extending in the longitudinal direction of the support beams 74 can also be used as supports for a plurality of floor elements 88. These floor elements 88, which are also known, for example, from scaffolding construction, can be suspended from the coupling beams 76 by means of coupling hooks 90 provided at their longitudinal end regions, so that a field delimited by four coupling bars 76, 76 or 78, 78 can be essentially completely laid out by a respective plurality of such floor elements 88.

[0050] The use of such floor elements 88, on the one hand, provides safety against falling for persons working on such a support system 70 or formwork system 72. On the other hand, a floor is created on which persons can move during the assembly of the formwork system 72, in particular for placing the cross beams 84 or the formwork elements 86.

[0051] Fig. 5 further illustrates that the coupling adapters 22, in addition to being able to couple coupling bars 76, 78 for stiffening, can also be used to couple auxiliary devices 92, 94 to the support system 70. The auxiliary device 92 is designed as a step floor arrangement with a floor element 95 and coupling rods 96, 98 coupling this to a respective support coupling adapter 22. Each of the coupling rods 96, 98 can be stably coupled to one of the perforated discs 40, 42 of a support coupling adapter 22 via a wedge head provided thereon and can support the associated floor element 95 in the same manner as was explained above with reference to the floor elements 88.

[0052] The auxiliary device 94 is designed, for example, as a railing, the vertical elements 100 of which can be coupled in their lower regions, for example, to one of the perforated discs 40, 42 of support coupling adapters 22 via wedge heads provided there or coupled thereto.

[0053] It should be noted that, of course, other auxiliary devices, particularly those known from scaffolding construction, can also be coupled to the support system 70 or the support coupling adapters 22 thereof. For example, a vertically constructed scaffold can be provided adjacent to or coupled to such a support system 70.

[0054] A support coupling adapter constructed according to the invention or a support assembly comprising such a support coupling adapter can be varied in various aspects. For example, in an alternative embodiment, a support coupling adapter can be designed with only a single adapter coupling element or a single perforated disc, which, due to its connection to the coupling housing, has a lateral offset from the coupling adapter's center axis. Such a support coupling adapter can be used, for example, in the edge areas of a support system where structural constraints prevent components from projecting beyond the centerline.

[0055] If necessary for weight savings and possible for stability reasons, the housing wall of the coupling housing of the support coupling adapter can be interrupted in the circumferential direction. For example, this can have interruptions in the corner areas of the housing base, so that sections of the circumferential wall extend essentially only along the longitudinal edges of the housing base. Alternatively, the housing wall can have interruptions in the area of ​​the longitudinal edges of the housing base and have wall sections extending over the corner areas of the housing base.

[0056] If the support coupling adapter is intended to be rotatable around the support's longitudinal axis with respect to a cooperating support, the coupling housing can be adapted to the support head in terms of its shape and / or size in such a way that the circumferentially acting positive connection between the housing wall and the support head is not created. For example, the support head can be designed with a circular outer peripheral contour, and the coupling housing can be designed with a correspondingly circular inner peripheral contour.
