The invention further relates to a connecting device for connecting at least two coverings of such a scaffold system and a lifting prevention device for preventing a lifting of a covering of a longitudinal or transverse bar of a scaffolding system.

Scaffolding systems, in particular industrial scaffold systems, are known in the prior art in a wide variety of configurations. Such scaffolding systems include longitudinal and transverse bars, between which pads are arranged and connected to them. For example, such industrial scaffolding systems are used to equip containers of industrial plants in order to at least temporarily reach upper regions of the container. For safety reasons, the coverings should be arranged and secured so that even with an uneven load of these, so force application to this, as when entering these, the pads do not stand out unilaterally. Such a lifting of the coverings from the covering unit or the surface could lead to a loosening in particular of the longitudinal and transverse bars and thus to a falling person on the scaffolding system.

For example, from the DE 20 2008 013 674 U1 is the hanging of coverings, which are provided on the edge with support / hooks, known in support bars, the support / hooks overlap a support edge. A safeguard against lifting the pads from the support bar is not disclosed here.

Also from the VO02006 / 045432 A1 is an industrial scaffolding with vertical supports, which are interconnected by means of horizontally extending latch, known, are hung in the bars to create a walk-work surface pads extending in a horizontal plane. The coverings each have on the front side hook elements, which serve for the connection, wherein the hook elements engage over the respective latch. Supporting elements are also provided on the front side of the lining, which can be supported on the one bar, which is overlapped by the hook elements. The pad also has lift-off in the form of steel straps that can be moved into designated recesses, the steel straps are moved under the bolt so that the bolt between the hook elements and the lift-off is fixed.

From the DE 196 05 972 A1 a scaffold with lift-off for scaffold floors is known, the framework has stems, horizontal longitudinal bar, horizontal cross bar and diagonal bar and horizontal support bar and optionally formed with horizontal support means consoles, as well as resting on these, displaced and lift-off scaffolding floors. As Abhubsicherungs aids a bent from a single metal wire AbhubsicherungsBügel is used. The Abhubsicherungsbügel has a lower holding part, which is formed with an elastically resilient Einführschenkel and a short Hintergreifschenkel, wherein on the holding part upwardly extending spacer legs are formed, which are angled in passing on opposite sides Abhubssicherungungsarme, which in turn on the surfaces of the scaffold floors rest.
From the DE 195 11 847 A1 Furthermore, a support structure element arrangement of a scaffold is known, which forms a torsion-resistant space structure with the aid of stems, horizontal bars and diagonal bars. Scaffold floors are displaced against horizontal support elements or bearing bolts by means of securing pins attached to them and secured against lifting by means of a bridging and lifting-off element. The latter has underside hooks which engage in openings of the horizontal support bar. The bridging and Abhubsicherungsplatte has support ends that with a support length rest on the console scaffold floors. In the middle of securing hooks are attached to its underside, which engage in security openings with slot-character. The hook ends of the safety hooks are below the support surface of the horizontal support member when the bridging and Abhubsicherungsplatte is moved in the direction of extending transversely to the longitudinal extent of the scaffolding floors securing opening. This type of Abhubsicherung is thus constructed comparatively complex.

From the DE 91 081 74 U1 is a mounting bracket for scaffolding constructed from scaffolding poles and provided with planks scaffolds, with an attachable to the scaffold rod attachment portion and a covering board detecting holding portion are provided. The mounting bracket is designed in particular integrally with mounting portion and holding portion, in particular bent wire. The attachment portion is designed as a holding portion away from the open, perpendicular to the longitudinal axis of the scaffold pole on this plug-disengageable spring clip with two the scaffold pole resilient comprehensive clip legs executed. Such a mounting bracket may possibly break in multiple use, is also not usable between individual planking, but only in combination with scaffolding poles.

The object of the present invention is therefore to provide a scaffolding system, in particular an industrial scaffold system, in which persons who enter and / or stand on the scaffold system experience maximum security through a particularly good connection of the individual components of the scaffold system with one another and can be achieved in a simple manner even with uneven weight load on the coverings of the scaffold system.

The object is achieved for a scaffold system according to the preamble of claim 1, characterized in that at least one rail-like connection means for connecting a head side of at least one covering is provided with at least one longitudinal side of an adjacent covering, said connecting means having at least a portion for covering a Part of the longitudinal side and / or engagement in a part of the longitudinal side of the one covering and provided with at least one connecting portion for engaging or engaging at least one or mesh with at least one fastening element of the at least one other adjacent lining, wherein the Abhebeverhinderungseinrichtung for preventing lifting of the with the at least one fastener provided covering is part of the connecting device. For a connecting device according to the preamble of claim 7, the object is achieved in that the connecting device is rail-like, comprises a substantially flat gate for covering a portion of an edge portion of a pad and a connecting portion for connection to the other pad, wherein the connecting portion is designed for engagement or engagement at least one or mesh with at least one fastener. For a Abhebeverhinderseinrichtung according to the preamble of claim 12, the object is achieved in that the Abhebeverhindernseinrichtung at least one covering the covering in an edge portion and at least one longitudinal or transverse bar at least partially embracing portion and at least one connectable to this and the longitudinal or Crossbar comprises at a discharge from the encompassing gate hindering security part. Further developments of the invention are defined in the dependent claims.

As a result, a scaffolding system, in particular an industrial scaffold system, is provided which allows a particularly high level of security for this person entering and moving on this person, this being achieved by combining a connection between the individual coverings of the scaffold system and the coverings of the scaffolding system with the longitudinal axis. and crossbars, and a lift-off prevention device is achieved. For coverings to be joined together, the lift-off prevention device is formed integrally with the connection device. To prevent lifting of a deposit from a longitudinal or transverse bar of the scaffold system, an additional Abhebeverhinderseinrichtung be provided so that a lifting of the pads both in the region of joints of two or more coverings as well as in the region of the connection with the transverse and Longitudinal bars can be achieved. The connecting device is formed like a rail, thus extending similar to a truss parallel to the head side or front edge of a covering, on the other hand parallel to the longitudinal side of the adjacent lining between the two linings.

Via the connecting portion of the rail-like connecting device, a connection with the one or more fastening elements of a covering is provided, wherein the connecting portion advantageously adapted to the fastening elements, which are arranged on this covering, is formed. Of the overlapping portion of the rail-like connecting device, an edge region of the longitudinal side of the adjacent lining, with which the first coating is to be connected, is covered. In this case, it is basically sufficient to provide only an overlapping of this edge region, but this overlapping section can also be provided with at least one connecting device which engages or engages with the upper side and / or a section in the edge region of the longitudinal side of this lining. In any case, the overlapping section is supported on the upper side of this covering in its edge region. As a result, both pads are connected to each other via the connecting device.

The lift-preventing means of the rail-type connecting means advantageously holds the at least one fixing member of the pad in the engaging position or engaging position with the connecting portion of the connecting means. In particular, the at least one fastening element of the lining can be at least partially covered by the lifting connection device and thereby prevented from leaving the connecting section of the rail-like connecting device. In particular, the lift-off prevention device may have the shape of at least one protruding section which is located so far away from the connecting section for covering the at least one fastening element that the fastening element can be held in its position connected to the connecting section, in particular in this engaging position. Such a section may be formed, for example in the form of a web, the between its underside and the top of the connecting portion of the connecting device leaves such a distance that the one or more fasteners of the there to be connected to the connecting device covering are covered with a small distance, so that after connecting the one or more fasteners with the connecting portion of the connecting device an unwanted Loosening of the fastener or of the connecting portion of the connecting device is securely prevented, the one or more fasteners are held in its interlocking with the connecting portion position. In this case, it is particularly sufficient if only one of a plurality of fastening elements held in its interlocking with the connecting portion of the connecting device position and the corresponding coating over this against lifting, thus releasing the connection of fastener and connecting portion of the connecting device is prevented. Of course, all fasteners can be overlapped by the Abhebeverhindernseinrichtung and held in its connecting position with the connecting portion of the connecting device.

Such a lift-off prevention device is much more stable than the prior art hangers and other lift-off prevention devices mentioned above. Furthermore, such a lifting prevention device, since it is mounted directly on the connecting device, thus no longer has to be arranged separately on the coverings, always available and need not be separately mounted or considered when building the scaffold or scaffolding system. The Abhebeverhinderseinrichtung is thus always mounted after the joining of two coverings on the connection means already, so that they can not be accidentally forgotten. This provides the highest level of security.

The connecting device can have connecting sections formed in a great variety of forms, for example also a connecting section, which is designed to be suitable in sections for connection to various types of fastening elements of coverings. Of the Connecting portion may for example have at least one edge for engaging a hook or claw-shaped or web-like fastening element and / or pins and / or pins and / or openings for engagement with openings or pins or pins of the covering. Furthermore, a wide variety of other configurations of the connecting portion of the connecting device are possible, so that an adapted to the here to be connected covering or its fasteners connection of the connecting device and the one or more fasteners of a respective covering is created.

The connecting device can furthermore have, in the region of the connecting section, at least one securing device for preventing a lateral escape or pushing out of the at least one fastening element of the lining from the connecting section. Such a securing device can be provided for example in the form of a web, which serves to prevent lateral pushing out of a hook, claw or web-shaped fastening element of the connecting device, in particular in the region of the connecting portion thereof. For example, two such webs may be provided on both sides at the respective end of the rail-like connecting device and laterally close the arrangement region for the fastening elements or lock there against an exit of the fastening elements.

Thus, head and long sides of two adjacent coverings can be connected to a covering unit of a scaffold system via the connecting device. The connecting device is supported on the one covering and holds the other covering firmly in the connecting device, wherein both coverings are also prevented by the connecting device at a lifting or moving against each other. The connection device itself does not lift off against both coverings. An unintentional lateral pushing out and thus separating one pad from the other by separating the one pad from the connecting device is prevented by the said advantageously provided safety devices, such as the aforementioned webs or otherwise formed safety devices.

In order additionally to prevent the scaffold system from lifting off the cover or pads which are suspended or connected to the longitudinal or transverse bars of the scaffold system, a second lift-off prevention device is advantageously provided for preventing lifting of a covering from its connecting position provided with a longitudinal or transverse bolt. The second lift-off prevention device comprises a section which overlaps an edge region of the lining and a section which encompasses the longitudinal or transverse tie and can be secured thereon. Such a second Abhebeverhinderungseinrichtung can thus protect a covering against lifting or unscrewing from its connection to a longitudinal or cross bar of the scaffolding system. In order to secure this lifting prevention device on the longitudinal or transverse bar, the lifting prevention device may comprise a securing part which secures the longitudinal or transverse bar at least partially engaged by the encompassing section in the encompassing section, wherein the securing part can be connected or connected to the encompassing section, in particular engages one another or intervene in these. The securing part prevents removal of the lift-preventing device from the longitudinal or transverse bar. Such a securing part can for example be designed as a securing element which can be inserted or inserted into openings of the encompassing portion. The lift-preventing device thus overlaps the covering to be secured and engages around the longitudinal or transverse bar, with which the covering is connected. In order to prevent the encompassing portion unintentionally detached from the longitudinal or transverse bar, the securing part is provided, which is arranged for example in a three-sided embrace by means of the encompassing portion on the fourth side of the embraced longitudinal or transverse bar, wherein the securing part with in particular the encompassing part is also connected.

In the encompassing section, for example, two slot-shaped openings can be provided, through which the securing part can pass and hold itself in this. This can be done for example by a wedge-shaped forming the security part. But the security part can also another in at least one direction in the openings in particular two have opposite leg of the encompassing portion of the lifting prevention self-locking shaping. The encompassing portion is, for example, approximately U-shaped in cross-section and comprises two limbs approximately opposite one another, wherein in each of the two limbs the at least one opening is provided for engagement or passage or for receiving the securing part. The securing part can also be held via a connecting element to the cross-over and / or the encompassing portion of the Abhebeverhindernseinrichtung. In this way it can be ensured that the securing part is not lost even when not mounted on a covering or longitudinal or cross bar Abhebeverhinderseinrichtung.

Due to the advantageous multi-sided, all-round or peripheral embracing of longitudinal or transverse bar on which the covering is fastened with its at least one fastening element, especially when the Abhebeverhinderungseinrichtung to prevent lifting of the pad from the longitudinal or transverse bar of the scaffold system between two fasteners is arranged, a displacement of Abhebeverhindernseinrichtung be prevented along the longitudinal or transverse bolt. Thus, not only lifting of the pad and thus releasing its fastener (s) from the connection with the longitudinal or transverse bar, but also a displacement of Abhebeverhindernseinrichtung along the longitudinal or transverse bar of the scaffold system can be prevented. The lift-preventing device thus acts at the desired location and does not move undesirably along the longitudinal or transverse bar. Advantageously, the entire Abhebeverhindernseinrichtung, in particular the section covering the covering to be secured, are dimensioned accordingly to absorb the possibly occurring lifting forces acting on the covering and thus on the overlapping portion of Abhebeverhindernseinrichtung with uneven force on the covering, and the coating in his To be able to hold the position in the covering unit.

Both the connecting device for connecting a head side of a covering with a longitudinal side of an adjacent covering and the Abhebeverhinderseinrichtung for preventing lifting and loosening of a covering, of a longitudinal or transverse bar can at various points along one side of the longitudinal side of the one pad, which is connected to the front side of the other pad and on the other hand along the front side of the associated with the longitudinal or cross bar pad to be ordered. Both the dimensions of the connecting device and in particular also of the connecting portion for connecting to the provided on the head side of the respective covering at least one fastening element and Abhebeverhinderseinrichtung the connecting device and the second Abhebeverhinderungseinrichtung, the detached from the connecting means of two coverings with each other on covering and cross or Longitudinal bar can be arranged, can be adapted to the particular scaffold system and the forces occurring.

Thus, compact covering units of a number of coverings and scaffolding systems with the aid of the connecting device and the Abhebeverhinderungseinrichtung can be created at this and optionally additionally provided second Abbebeverbindungseinrichtung. Both the connection device and the second Abhebeverhinderungseinrichtung are not only simple in itself, but can be easily assembled and disassembled, so that even with frequent assembly and disassembly of scaffolding not or at least hardly the risk of damage to the connecting device or the Abhebeverhindernseinrichtung is to be feared.

Both the connection device and the second Abhebeverhinderungseinrichtung may consist of a metal, for example, formed of metal plates or metal strip or be made as a casting. Also, the use of other materials is possible, solid and stable materials are preferred here for permanent use, optionally also mixed materials which have a special stability.

FIG. 1 shows a top perspective view of a scaffold system 1 with two longitudinal bars 2, 3 and two cross bars 4, 5 which are connected to each other via corner posts 6, 7, 8, 9. The corner supports are each arranged at a corner of the scaffold system in approximately vertical positioning in the room. Between the opposing crossbars 4, 5 more pads 10, 11, 12, 13, 14, 15, 18, 19, 20, 21 are arranged and connected thereto. The pads 10, 11, 12, 13, 14, 15 each have two head sides 100, 101, 102, 103, 104, 105, 180, 190, 200, 201, 202, 203, 204, 205, 280, 290 and respectively two mutually approximately parallel longitudinal sides 181, 191, 281, 291, 300, 301, 302, 303, 304, 305 and 400, 401, 402, 403, 404, 405 on. The pads 20, 21 are trapezoidal and have head sides 206, 207, 208, 209 and longitudinal sides 210, 211 and 212, 213 of different lengths. The head sides of all coverings are provided with fastening elements in the form of hooks or claws 16. With these fasteners 16, the pads 10, 11, 12, 13, 14, 15 engage the front side of each of the cross bars 4, 5 and hold on to these. Only the pads 13, 14 are each provided at a front or head end with the fasteners 16, wherein the pad 13 on the Cross bar 4 and the pad 14 is releasably secured to the cross bar 5 via the fasteners 16. The pads 13, 14 are spaced apart so that between their ends and the respective adjacent pads 12, 15, an opening 17 is defined, through which, for example, a ladder or other component to be converted by the scaffold system, can be accommodated.

Furthermore, the coverings 11, 12 are spaced apart from one another, wherein the two further coverings 18, 19 are arranged between them approximately perpendicular to these. The pads 18, 19 are connected via two connecting devices 20 each with the adjacent pads 11, 12. About two further connection means 20, the two further trapezoidal pads 21, 22 are connected to the pad 11 and the pad 18. These coverings 21, 22 are used, for example, a diagonal stiffening of the scaffold system, can also serve for oblique covering of components that are rebuilt by the scaffold system or are at least partially surrounded by this.

All pads 10 to 15, 18, 19, 21, 22 together with the transverse and longitudinal bars 2 to 5 a pad unit 23. In particular one-sided lifting the pads from the created pad unit 23, thus from the created horizontal plane (in space ), not only the connection means 20 are provided with respective Abbebeverbindungseinrichtungen 126, but additional Abhebeverbindungseinrichtungen 30 are provided. In the in FIG. 1 shown embodiment, four such Abhebeverbindungseinrichtungen 30 on the pad unit 23, two at the two head ends 101, 102, 201, 202 of the pads 11 and 12, respectively. These Abhebeverbindseinrichtungen 30 are discussed in more detail to FIG. 3 and the connecting device 20 with the provided on this Abhebeverbindungseinrichtungen 126 for FIG. 2 described.

FIG. 2 shows a detailed perspective view of the linings 11 and 19 with the connecting device 20 connecting them. The connecting device 20 comprises a longitudinal edge region 110 of the covering 11 overlapping portion 120 and a connecting portion 121 for connecting to the Fastening elements 16, which are arranged on the head side 190 of the pad 19. The connecting portion 121 is formed as a flat plate-like member, wherein both the overlapping portion 120 and the connecting portion 121 are each formed as L-shaped portions which are interconnected in the region of a joint 122, for example by welding. In principle, it is also possible to form the entire connecting device 120 in one piece, it being possible for the individual sections to be formed by repeatedly bending over a sheet metal.

The fastening elements 16 designed as hooks or claws overlap the flat plate-like connecting section 121, as in FIG FIG. 2 shown. In order to prevent lateral slipping out of the connecting device 20, lateral webs 123, 124 are provided on the connecting device 20 between the connecting section 121 and the overlapping section 120. The webs may for example be attached to both sections 120, 121 by welding or brazing or another joining method. They extend between the two mutually approximately parallel portions of the connecting portion 121 and the overlapping portion 120, in the latter attached to the connecting portion 121 approximately parallel to the outside of the edge 111 of the pad 11 supporting portion 125 of the overlapping portion 120th A lateral slipping out of the fastening elements 16 of the pad 19 from the channel formed by the portion 125 and the connecting portion 121 of the connecting device 20 can be prevented via the webs 123, 124.

A lifting of the pad 11 against the pad 19 is prevented by the overlapping portion 120 of the connecting device 20. A lifting of the pad 19 against the pad 11 is prevented by the Abhebeverhinderseinrichtung 126 in the form of a plate-like web which protrudes approximately perpendicularly from the portion 125 of the connecting device 20 and which extends at attached to the connecting portion 121 fastener 16 above this. The plate-shaped lift-off prevention device 126 leaves to the upper extent of the connecting portion 121 of the connecting device 20 just so much space that the fastening element 16 to be arranged there between Abhebeverhindernseinrichtung 126 and the upper extension of the connecting portion 121 can be arranged, but lifting is not possible, only a lateral threading under this. Lifting out the fastening device 16 from the connecting device 20, that is to say lifting it off the connecting section 121 therefrom, is thus no longer possible there for the fastening element 16. Accordingly, a lifting of the pad 19 is no longer possible here.

In order to prevent lifting of the lining 11 from the cross bar 5, the lift-off prevention device 30 is provided, which in one embodiment in FIG FIG. 3 is shown. The covering 11 engages with its two fastening elements 16 in the form of hooks or claws on the U-shaped crossbar 5 in profile. Without the provision of Abhebeverhindernseinrichtung 30, a separation of this compound of pad 11 and crossbar 5 would be readily possible. However, this can be securely prevented by the lift-off prevention device 30. For this purpose, the lift-off prevention device 30 comprises a section 130 overlapping or covering the covering 11 on the upper side 112 thereof. The covering section 130 merges into a section 131 arranged approximately perpendicularly thereto, located on the front side of the covering, ie on the front side 113 of FIG Pads 11 is supported. The section 131 of the Abhebeverhindernseinrichtung 30 goes approximately at right angles to this about in a U-shaped, the crossbar 5 on three sides embracing portion 132. The U-shaped encompassing portion 132 thus has two mutually approximately parallel legs 133, 134 with a arranged between them, to the two legs 133, 134 about vertically arranged third leg 135. In the in FIG. 3 shown embodiment, the leg 134 is formed about longer than the leg 133, wherein both legs 133, 134 are each provided with a slot-shaped opening 136, 137. The two slot-shaped openings 136, 137 are advantageously aligned approximately one above the other, have in the in FIG. 3 However, shown embodiment, a different length or different dimensions. The opening 137 is shorter than the opening 136. This serves to slippage of a fuse element 140 through the two slit-shaped openings 136, 137 to prevent. The securing element 140 is wedge-shaped to allow locking in the openings 136, 137. The fuse element 140 has a wider end 141 and a narrower end 142. The wider end 141 is wider than the length of the slot-shaped opening 136 would correspond, so that a complete passage of the fuse element 140 through the slot-shaped opening 136 can be avoided.

After the U-shaped encompassing portion 132 already encompasses three sides of the transverse bar 5, after the insertion of the securing element 140 into the two slot-shaped openings 136, 137 in the two legs 133, 134 of the U-shaped encompassing portion 132 of the transverse bars 5 also becomes embraced its fourth side, so that the encompassing portion 132 in combination with the securing element 140 allows a complete embracing and holding the Abhebeverhindernseinrichtung 30 on the crossbar 5. Since the Abhebeverhindernseinrichtung 30 additionally supported with the two sections 130, 131 on two mutually perpendicular sides of the pad 11 and acts on these, a relative movement of pad 11 and cross bar 5 can be safely avoided. In this case, the securing element 140 can also be supported with its wider end 141 in addition to the section 131 of the Abhebeverhindernseinrichtung 30, so that a loosening of the connection of Abhebeverhindernseinrichtung 30 and cross bar 5 also hereby can be additionally prevented.

By arranging the lift-off prevention device 30 between the two fastening elements 16, these fastening elements 16 secure the lift-off prevention device 30 against lateral displacement and unintentional removal from the transverse bar, whereby the four-sided or circumferential embracing of the transverse bar 5 by the lift-off prevention device 30 depending on the choice of the positioning of the slot-shaped openings 136, 137 and accordingly of the securing element 140 with respect to the respective wall of the transverse bar 5, the Abhebeverhinderungseinrichtung more or less firmly on the outside of the cross bar 5 holds. The cross bar 5 is in FIG. 3 when U-profile shown, but may also have a different shape, wherein the shape of the Abhebeverhindernseinrichtung 30, in particular of the encompassing portion 132 can be adapted to the respective shape of the cross bar 5.

Thus, over the provision of the connecting device 20 and the Abhebeverhinderungseinrichtung 30 an unwanted lifting individual pads from the plane of the pad unit 23 can be safely avoided, thus providing a high level of security for the person entering the scaffold system 1 persons. Already by arranging the connecting device 20 not only the approximately perpendicular to each other or arranged at an angle to each other pads can be securely connected to each other, but at the same time fixed their positioning relative to each other or secured and lifting the respective pads even with uneven force on this solely by the provision of the connecting device 20 can be safely avoided, as already in this a Abhebeverhindernseinrichtung is integrated.

In addition to the embodiments of scaffolding systems, in particular industrial scaffolding systems, connecting devices for these and Abhebeverhindernseinrichtungen for these described above and in the form of numerous other can be formed, in particular combinations of said embodiments for different types of coverings, wherein in each case the connecting portions of the connecting devices the respective fastening elements of the coverings can be suitably adapted or can be. In each case, a connection of a fastening element provided with a side facing a covering with a fastener without provided side of an adjacent covering is possible via the rail-like connection means, wherein the connecting means on the one hand covers a part, portion or area of the side without fasteners of a covering and on the other comprises the connecting portion for connection to the other covering or its fastening elements and at the same time comprises a Abhebeverbindungseinrichtung, the unintentional release of the at least one fastening element of the covering from the connection with the Prevents connecting portion of the connecting device or from the connection with a longitudinal or transverse latch of the scaffolding system.
