Description

[0001] Support system, especially for a formwork system Description

[0002] The present invention relates to a support system, in particular for a formwork system.

[0003] EP 3 443 179 B1 discloses a formwork system constructed with a support system comprising a plurality of support units standing on a substrate and support beam assemblies supported thereon above the substrate. The support beam assemblies each comprise a plurality of support beams arranged one after the other in a longitudinal direction. Between support beam assemblies immediately adjacent to one another transversely to the longitudinal direction of the support beams or support beam assemblies, a safety arrangement is provided in each case, which is intended to protect persons involved in the assembly of the formwork system from falling. Each such safety arrangement comprises, associated with each of the two immediately adjacent support beam assemblies, a rail device having rail devices designed as profile elements arranged one after the other in the longitudinal direction of the support beam assemblies.A safety device with several safety units arranged one after the other in the longitudinal direction and displaceable in the longitudinal direction on the rail devices is carried on the rail devices assigned to the two immediately adjacent support beam arrangements.

[0004] It is the object of the present invention to provide a support system, in particular for a formwork system, which has increased structural strength.

[0005] According to the invention, this object is achieved by a support system, in particular for a formwork system, comprising a plurality of support beam arrangements elongated in a longitudinal direction, wherein each support beam arrangement is carried on a plurality of support units extending substantially in a height direction and at least two support beam arrangements are arranged at a distance from one another in a transverse direction transverse to the longitudinal direction, wherein in association with at least two support beam arrangements arranged directly adjacent to one another in the transverse direction, a safety arrangement is provided which is positioned in the height direction under a respective support beam arrangement support surface of the support beam arrangements arranged directly adjacent to one another in the transverse direction,wherein the safety arrangement, in association with each of the two support beam arrangements arranged immediately adjacent to one another, comprises a rail device extending substantially in the longitudinal direction and a safety device carried on the rail devices and at least partially covering a space between the two support beam arrangements arranged immediately adjacent to one another in the longitudinal direction, wherein each rail device comprises at least one, preferably a plurality of rail units following one another in the longitudinal direction, wherein at least one, preferably each rail unit comprises: a coupling part extending substantially in the longitudinal direction, wherein the coupling part has a coupling unit for coupling to one of the support units in each of its longitudinal end regions lying at a distance from one another in the longitudinal direction, a coupling unit firmly connected to the coupling part,in the height direction above the coupling part, the supporting part extending substantially parallel to the coupling part in the longitudinal direction.

[0006] In the support system according to the invention, by structurally separating the functions of coupling to support units on the one hand and carrying a safety device on the other hand, the system areas of the rail devices provided for this purpose, i.e. the coupling part on the one hand and the carrying part on the other hand, can be designed with a design optimized for fulfilling the respective assigned function.

[0007] For example, at least one, preferably each, support unit intended for coupling to a rail unit can comprise a support and, in an upper end region of the support in the vertical direction, at least one coupling element arranged offset transversely to the vertical direction relative to the support and preferably detachably coupled to the support, for coupling at least one coupling unit. A conventional construction support can be provided as such a support, which has a high load-bearing capacity while being simple and therefore cost-effective in design.

[0008] For increased variability in the structure, it is proposed that at least one, preferably each support unit provided for coupling to a rail unit comprises two coupling elements arranged transversely to the height direction with respect to the support and offset in opposite directions, each for coupling at least one coupling unit, and / or that at least one, preferably each coupling element comprises a perforated disc and at least one, preferably each coupling unit comprises a wedge head.

[0009] In order not to impair the coupling function to be realized in the region of the coupling part by the support part provided in a respective rail unit, it is proposed that the support part is offset with respect to the coupling part in the transverse direction, preferably in the direction of a support beam arrangement immediately adjacent in the transverse direction, and / or that in at least one, preferably each of its longitudinal end regions, the coupling part is shorter in the longitudinal direction than the support part, so that the support part extends beyond the coupling part in the longitudinal direction, preferably wherein all support parts immediately following one another in the longitudinal direction form a support structure which runs essentially without interruption in the longitudinal direction.

[0010] In an alternative construction which, above all, has a high mechanical stability, it can be provided that the support part is substantially not offset in the transverse direction with respect to the coupling part, and / or that in at least one, preferably each of its longitudinal end regions, the coupling part is longer in the longitudinal direction than the support part, so that the coupling part extends beyond the support part in the longitudinal direction.

[0011] In order to be able to achieve a structure of the support parts of directly successive rail units that runs continuously in the longitudinal direction in this embodiment without impairing the coupling function of the coupling part, it is proposed that the rail device, in association with at least two, preferably all, rail units that run directly one after the other in the longitudinal direction, comprise a support part adapter that adjoins the support parts of the directly successive rail units, preferably wherein all the support parts and support part adapters that run directly one after the other in the longitudinal direction form a support structure that runs continuously in the longitudinal direction essentially without interruption.

[0012] A high strength of the rail units can be achieved, for example, in that in at least one, preferably each rail unit, the coupling part and the support part are firmly connected to one another by a plurality of connecting elements arranged at a distance from one another in the longitudinal direction, for example by material bonding, such as welding, and / or in that in at least one, preferably each rail unit, the coupling part and / or the support part is designed in a tubular manner.

[0013] For a structure of the support system that is variable in the longitudinal direction and adapted to the given requirements, at least one, preferably each support beam arrangement can comprise at least one support beam that is elongated in the longitudinal direction, and / or at least one, preferably each support beam arrangement can comprise at least two support beams that are elongated in the longitudinal direction and adjoin one another in a connection region, preferably overlapping one another in the longitudinal direction.

[0014] The safety device can comprise at least one safety unit carried on the support parts of two rail devices, wherein the at least one safety unit comprises coupling elements in association with the rail devices carrying it, wherein the at least one safety unit is substantially blocked by the coupling elements on the rail devices carrying it against movement in the vertical direction downwards and against movement in the transverse direction, preferably wherein the at least one safety unit is not blocked by the coupling elements on the rail devices carrying it against movement in the longitudinal direction.Depending on the intended use, it can be provided that at least one safety unit comprises: a floor element which is elongated in the transverse direction and has the coupling elements in its longitudinal end regions, or a preferably substantially rectangular safety frame and a safety net or safety grid carried on the safety frame, wherein the coupling elements are provided on frame sections of the safety frame which are arranged at a distance from one another in the transverse direction and extend in the longitudinal direction, or.

[0015] - a safety floor assembly comprising two transversely elongated and longitudinally spaced-apart cross elements and a plurality of longitudinally elongated and transversely juxtaposed floor elements, wherein the coupling elements are provided at longitudinal end regions of the transverse elements spaced-apart in the transverse direction and the floor elements are coupled to the transverse elements at their longitudinal end regions spaced-apart in the longitudinal direction.

[0016] It goes without saying that different designs of such a safety unit can be combined with one another in a support system.

[0017] For further increased safety, at least one safety railing arrangement may be provided, wherein the at least one safety railing arrangement comprises two vertical elements extending substantially in the height direction and arranged at a distance from one another in the transverse direction, wherein each of the two vertical elements is designed for coupling to a rail device.

[0018] For a simple coupling of the safety railing arrangement to the support system, each of the two vertical elements for coupling to a rail device can comprise two coupling hook elements arranged at a distance from one another and open in opposite directions, wherein the distance between the coupling hook elements is greater than the width of the support part in the transverse direction, and wherein the coupling hook elements are positioned in an intermediate coupling position transversely to the longitudinal direction on both sides of the support part after a respective vertical element has been placed on the support part and are positioned at least partially encompassing the support part by rotating the vertical element from the intermediate coupling position, preferably by 90°, into a coupling end position.

[0019] Safety can be increased by the interaction of such a safety railing arrangement with a safety unit in that at least one safety railing arrangement can be coupled to at least one safety unit to provide an assembly coupled together in the longitudinal direction.

[0020] The invention further relates to a formwork system comprising a support system constructed according to the invention and at least one, preferably a plurality of formwork elements carried on the support system.

[0021] For efficient support of such formwork elements, they can be carried on the support beam arrangements via a plurality of intermediate beams extending substantially in the transverse direction.

[0022] At least one, preferably each circuit element may comprise: a formwork panel, or a lost circuit element, preferably made of concrete material.

[0037] Fig. 15 shows a further detailed view of the support system with the rail unit shown in Fig. 13. Fig. 1 shows a formwork system 12 comprising a support system 10, for example, for constructing a formwork intended for the production of a concrete slab.

[0038] The support system 10 comprises a plurality of support units 14, which stand on a base in a foot region 16 to be positioned downwards in a height direction H substantially corresponding to a vertical direction, and each carry a support beam arrangement 20 in a head region 18 to be positioned upwards in the height direction H.

[0039] Such a support unit 14 is shown in detail in Figs. 3 and 4. The support unit 14 comprises a support 26, designed, for example, as a construction support, and having shaft parts 22, 24 that can be locked in different positions relative to one another. The foot region 16 is formed on the shaft part 22, and the head region 18 is formed on the shaft part 24 inserted into the shaft part 22.

[0040] The head region 18 comprises a support coupling adapter, generally designated 28, and a holding head, generally designated 30. The support coupling adapter 28 comprises a central, housing-like support coupling part 32 and two oppositely oriented sides of the housing-like support coupling part 32, each with a coupling element 34, 36 designed as a perforated disc. When the support coupling part 32 rests on a plate-like support head 38 of the upper shaft part 24, a through-opening 40 formed therein is aligned with a through-opening 42 formed in the support head 38.

[0041] The holding head 30 is formed with a plate-like holding head base 44 and a holding head coupling projection 46 extending therefrom. When the support coupling part 32 rests on the support head 38, the holding head coupling projection 46 can be guided through the two mutually aligned through-openings 40, 42, so that the holding head 30 rests rotatably on the support coupling part 32 or the support head 38, and the support coupling adapter 28 is held on the support 26 by the holding head 30. The support coupling adapter 28 is held against rotation relative to the support 26 by the interaction of the support coupling part 32 with the support head 38.

[0042] Four holding projections 48, 50, 52, 54 extend from the holding head base 44, by means of which the support beam arrangements 20 to be supported on the support units 14 or to be held thereon are held stably against lateral movement, i.e. against movement in a transverse direction Q.

[0043] As can be seen in Fig. 1, each of the support beam assemblies 20 can comprise a plurality of support beams 56 arranged successively in a longitudinal direction L and overlapping one another in the longitudinal direction L in an adjacent region. The support beams 56 are supported at their end regions located in the longitudinal direction L, in particular where two such support beams 56 overlap in the longitudinal direction L, by one of the support units 14 shown in Figs. 3 and 4. In intermediate regions, the support beams 56 can be supported in the height direction H by supports 26 without using a support coupling adapter 28 and a holding head 30.

[0044] The support system 10 comprises, in association with each of the support beam assemblies 20 arranged in pairs adjacent to one another in the transverse direction Q, a safety assembly, generally designated 58. Each such safety assembly 58 comprises, in association with each of the two support beam assemblies 20 arranged adjacent to one another in the transverse direction Q, a rail assembly 60, 62 extending in the longitudinal direction L and a safety assembly 64 carried on these rail assembly assemblies 60, 62. The safety assemblies 58 provided in association with the respective support beam assemblies 20 arranged adjacent to one another in pairs are integrated into the support system 10 such that the safety assemblies 58 are positioned in the height direction H below support beam assembly support surfaces 66 of the support beam assemblies 20 or the support beams 56 thereof.This makes it possible to install structural elements of the formwork system 12, such as intermediate beams 68 extending substantially in the transverse direction Q and resting on the support beam arrangement support surfaces 66, and formwork elements 70 to be positioned thereon, without being impaired by the safety arrangements 58 on the support beam arrangements 20 or the support beams 56 of the same.

[0045] The rail devices 60, 62 extending in the longitudinal direction L each comprise, for example, in association with each support beam 56, a rail unit 70 shown in Figs. 5 and 6. The rail units 70 of the rail devices 60, 62, which are preferably constructed identically to one another, each comprise a coupling part 72, for example designed as a tube and elongated in the longitudinal direction L, and a support part 78 extending essentially parallel to the coupling part 72, firmly connected to the coupling part 72 by a plurality of connecting elements 74, 76 and, for example, also designed as a tube. The coupling part 72 and the support part 78 can be firmly connected to the connecting elements 74, 76, for example by material bonding, in particular welding, to provide a stable structure.

[0046] The coupling part 72 has a coupling unit 84, 86 designed as a wedge head at each of its longitudinal end regions 80, 82 located in the longitudinal direction L. By means of these coupling units 84, 86, the rail units 70 can be coupled at the longitudinal end regions 80, 82 of the coupling parts 72 to one of the coupling elements 34 or 36, respectively, of the support units 14, designed as perforated discs. By coupling the rail units 70 to the support coupling adapters 28 of the support units 14, not only is a stable integration of the rail units 70 into the support system 10 achieved, but the support system 10 itself is also stiffened.For this purpose, in addition to the rail units 70 extending in the longitudinal direction L between each two support units 14, coupling bars 88 extending in the transverse direction Q between two support units 14 can also be used, so that a network extending over the entire support system 10 is created from elements stiffening it in the longitudinal direction L and in the transverse direction Q. It should be noted that, in the sense of the present invention, the coupling of two components or assemblies means that they can be repeatedly connected to one another, i.e. coupled, and can also be detached from one another again without destructive influence.

[0047] Figs. 6 and 10 illustrate that in the rail units 70, the support part 78 is offset transversely to the height direction H, i.e., in the transverse direction Q, relative to the coupling part 72, specifically in the direction of a directly adjacent support beam 56. This results in the coupling units 84, 86 provided at the longitudinal end regions 80, 82 in the height direction H and designed as wedge heads not being covered by the support part 78 extending in the longitudinal direction L beyond the respective longitudinal end region 80, 82 of the coupling part 72. Thus, it is possible to move the coupling wedges 90 provided on the coupling units 84, 86 designed as wedge heads in the vertical direction in order to establish and release the coupling of the coupling units 84, 86 with the coupling members 34 and 36 designed as perforated discs, without being impaired by a support part 78 extending thereabove.

[0048] As illustrated in Figures 8 and 9, the lateral offset of the support parts 78 with respect to the coupling parts 72 of the rail units 70 directly adjoining one another in the longitudinal direction L enables the support parts 78 of the latter to extend so far in the longitudinal direction L beyond the coupling parts 72 of the latter that a support structure 92 is formed which is essentially uninterrupted in the longitudinal direction L. Only in a region of this support structure 92 lying essentially centrally above the coupling elements 34, 36, in which region the two support parts 78, 78 of two directly adjoining rail units 70, 70 adjoin one another, is there a short interruption which does not impair the essentially continuous structure of the support structure 92.

[0049] Fig. 1 shows various designs of the safety device 64 in connection with the two pairs of support beam assemblies 20 extending parallel to one another. In the pair of adjacent support beam assemblies 20 shown top right in Fig. 1 and the rail devices 60, 62 somewhat associated with them, the safety device 64 comprises a plurality of safety units 94 arranged one after the other in the longitudinal direction L. Each such safety unit 94 is constructed with a substantially rectangular, in particular square, safety frame 96 and a safety grid 98 or safety net attached thereto. On frame sections of the safety frame 96 extending in the longitudinal direction L, a plurality of spaced-apart safety units 94 are each arranged in Fig.7 and 8, which engage around the support parts 78 of the rail units 60, 62 from above and thereby hold the safety units 94 against falling in the vertical direction and against movement in the transverse direction on the rail devices 60, 62. Nevertheless, the safety units 94 can be displaced on the support parts 78 of the rail devices 60, 62 in the longitudinal direction L, so that, depending on the construction progress during the assembly of the formwork system 12, the safety units 94 can be displaced such that they can always be positioned adjacent to the area of ​​the formwork system 12 already covered by formwork elements 70. As Fig. 1 illustrates, a full-surface design of the intermediate space formed between the pairs of support beam arrangements 20 lying next to one another in the longitudinal direction L is therefore not absolutely necessary.

[0050] In the area located at the front left in Fig. 1, or between the support beam assemblies 20 running side by side, which can be seen there, the safety device 64 provided in association with these two support beam assemblies 20 comprises a plurality of floor elements 102, also visible in Fig. 7, such as are known, for example, from scaffolding construction. The floor elements 102, which are elongated in the transverse direction Q, are arranged one after the other in the longitudinal direction L, essentially without any space between them, and are supported by hook-like coupling elements 100 provided at their longitudinal end regions on the support parts 78 of the rail devices 60, 62 provided in association with these support beam assemblies 20.These safety units 94', designed as floor elements 102, can also be moved in principle in the longitudinal direction R on the supporting parts 78 of the rail devices 60, 62 that support them, in order to be able to adapt their positioning to the progress in the construction of the formwork system 70.

[0051] In the configuration of the support system 10 or the formwork system 12 constructed therewith shown in Fig. 2, the spaces formed between the support beam assemblies 20 arranged side by side in pairs are completely occupied by the respective safety devices 64. For this purpose, both the safety units 94' constructed with a safety frame 96 and a safety grating 98 or safety net, as well as the safety units 94' constructed in the form of floor elements 102, can be used. With such a configuration, regardless of the construction progress of the formwork system 12, a displacement of the safety units 94 or 94' is not necessary.

[0052] A further alternative embodiment of the safety device 64 or a safety unit 94" thereof is shown in Figs. 10 to 12. The safety unit 94" is designed as a safety floor assembly 97, which comprises two transverse elements 104, 106 extending substantially in the transverse direction Q and arranged at a distance from one another in the longitudinal direction L. Each of the transverse elements 104, 106 has, in its longitudinal end regions, the previously mentioned hook-like coupling elements 100, with which they can be slidably coupled to the support parts 78 of the rail devices 60, 62 in the longitudinal direction L.

[0053] The two transverse elements 104, 106 are designed, for example, as U-profiles open upwards in the vertical direction H. Floor elements 108 extending between the two transverse elements 104, 106 are coupled to the transverse elements 104, 106 by hook-like coupling elements 110 provided at their longitudinal end regions, thus creating a stable assembly in the longitudinal direction L, which, if necessary, can also be displaced in the longitudinal direction L on the support parts 78 of the rail devices 60, 62 supporting them.

[0054] In association with the safety unit 94" designed as a safety floor assembly 97, a safety railing arrangement 112 is also provided. The safety railing arrangement 112 comprises two vertical elements 114, 116 arranged next to one another in the transverse direction Q. Several perforated discs can be provided at a distance from one another on the vertical elements 114, 116, to which horizontal elements 118 of the safety railing arrangement 112 can be coupled.

[0055] In their lower regions in the vertical direction H, the vertical elements 114 are each designed for coupling to the support part 78 of one of the rail devices 60, 62. For this purpose, two coupling hook elements 124, 126 are fixed to the vertical elements 114, 116 at a distance from one another and oriented opposite to one another. The mutual spacing of the coupling hook elements 124, 126 is matched to the width or diameter of the support parts 78 such that the vertical elements 114, 116 can be pushed from above onto a respective associated support part 78, for example, until the vertical elements 114, 116 rest on the associated support parts 78. Subsequently, the vertical elements 114, 116 are rotated by 90° from the initially existing intermediate coupling position, so that the coupling hook elements 124, 126 are arranged at a distance from one another and oriented opposite to one another.12, the coupling end position of the coupling hook elements 124, 126 is reached, in which they engage around the outside of the respective associated support part 78 on opposite sides in the transverse direction and overlap downwards. As a result, the vertical elements 114, 116, which are prevented from twisting by the horizontal elements 118 then coupled to them, are firmly coupled to the associated support parts 78 in the vertical direction H and the transverse direction Q, but are displaceable on the support parts 78 in the longitudinal direction L.

[0056] In order to also be able to establish a coupling between one of the cross elements 104, 106 in the safety railing arrangement 112, hook-like coupling elements 128 can be provided on the cross elements 104, 106 in their respective longitudinal end regions. After the safety railing arrangement 112 has been coupled to the rail devices 60, 62, these coupling elements are moved via the coupling hook elements 124 and 126 facing the safety unit 94" and are thus coupled with them for joint movement in the longitudinal direction L. This creates a firm connection between the safety unit 94" and the safety railing arrangement 112, so that these two assemblies can be moved together in the longitudinal direction L on the associated rail devices 60, 62, if necessary, in accordance with the construction progress during the assembly of the formwork system 12.

[0057] An alternative embodiment of the rail devices 60, 62 or the rail units 70 thereof is shown in Figs. 13 to 15. In this embodiment, the rail units 70 are designed or coupled to the support units 14 in such a way that, in the installed state, the support parts 78 thereof are positioned in the height direction H directly above the coupling parts 72. In order to create the possibility, in this embodiment, which is advantageous for static reasons, of being able to couple coupling units 84, 86 provided in the longitudinal end regions 80, 82 of the coupling parts 72 and designed as wedge heads to the coupling elements 34 or 36 designed as perforated disks, the coupling parts 72 are designed such that they extend beyond the associated support parts 78 in the longitudinal end regions 80, 82.

[0058] In order to bridge the gap resulting in the installed state between the support parts of two rail units 70 directly following one another in the longitudinal direction L, a support part adapter 130 is provided in association with each such pair of support parts 78 directly following one another in the longitudinal direction L. The support part adapter 130 can have the same outer circumferential contour as the support parts 78, and can therefore also be tubular in the illustrated embodiment. For secure coupling and thus for producing a support structure 92 that runs essentially continuously in the longitudinal direction L, the support part adapter 130 can have insertion sections with smaller outer dimensions in its end regions, which are inserted into end openings of the tubular support parts 78.Alternatively, such sections with a small diameter can also be provided at the longitudinal end regions of the support parts 78, or such a section with a smaller cross-sectional dimension can be provided at a longitudinal end region of the support parts 78 and, accordingly, such a section with a smaller dimension can be provided only at one end region of the support part adapters 130. Other types of coupling are also possible, in which, for example, the support part adapters 130 are inserted from above into corresponding recesses in the support parts 78. It should be noted that in the various illustrated embodiments of the rail units, the support part in particular could also be designed in a different shape. For example, it could also be designed as a hollow profile into which corresponding coupling elements of the safety units to be carried or guided thereon can engage.In order to couple the safety units to the rail units, particularly if easy movement is to be ensured, the safety units can also have wheels which can then roll on the support parts forming the support structures running through in the longitudinal direction.
