DETAILED DESCRIPTION

[0027] A scaffolding arrangement according to the invention comprises, as essential components, an anchor bolt 1 designed for fixing to a building wall 36, a length compensating adapter 6, a tube clamp 4, a rail 3 fixed to tube clamp 4, as well as a scaffolding 2 and a connecting device 5 for connecting scaffolding 2 to rail 3. Scaffolding 2, which is illustrated in a grid-like manner by way of example in FIG. 1, and which is four standard breadths wide and five standard heights high, comprises a plurality of system frames 16 spaced a distance apart horizontally and arranged one above the other vertically, decks 17 arranged between system frames 16, rail posts 18, which are provided between system frames 16, height-adjustable threaded feet 22 as well as longitudinally extended toe boards 20 and transversely extended toe boards 21. Cross-braces 19 are also provided to reinforce scaffolding 2. Of course, the scaffolding may also have two additional elements, which are not illustrated, for example, stairs, ladders or end rails.

[0028] Rail 3 is used to indirectly fix scaffolding 2 to building wall 36, which is not illustrated in FIGS. 1 and 2. Rail 3 extends horizontally. Each rail 3 is provided at a distance of two standard scaffolding heights apart. The distance between the horizontally extending rails is thus approximately 4 meters. Rail 3 is formed by multiple rail elements 3.1, 3.2 inserted into each other. Rail elements 3.1, 3.2 inserted into each other are interconnected and fixed to each other via a ball catch.

[0029] Connecting device 5 is used to fix scaffolding 2 to rail 3. Connecting device 5 comprises a first coupling 30 as well as a second coupling 32. First coupling 30 and second coupling 32 are each designed in the manner of double clamps. Couplings 30, 32 are connected via a tube 29 of connecting device 5 acting as a coupling connector. Couplings 30, 32 are detachably and displaceably held on tube 29. Due to the detachable and displaceable fixing of couplings 30, 32 to tube 29, a distance between scaffolding 2 and rail 3 may be set variably or as needed, and tolerances may be compensated for.

[0030] Rail 3 is fixed to building wall 36 via anchor bolt 1, tube clamp 4 as well as length compensating adapter 6; cf. FIGS. 3 and 4. Anchor bolt 1 is designed as a multi-part anchor bolt 1, including a load distribution plate 7, a supporting body 8 and a threaded element 13 encompassed by supporting body 8. Load distribution plate 7 is preferably formed from a metallic material. It is supported on building wall 36 via a hardening compensating compound. The compensating compound is used to level unevennesses in building wall 36 and ensures a contact of load distribution plate 7 over a wide area. Supporting body 8 has a first end face 9 facing load distribution plate 7 as well as a second end face 10, which faces tube clamps 4 or scaffolding 2 in the mounted state. Supporting body 8 of anchor bolt 1 tapers from first end face 9 in the direction of second end face 10. It provides a radially oriented rib 11, which is used to preferably effectively absorb transverse forces transferred from the scaffolding to the anchor bolt via the rail. In addition, supporting body 8 provides a tubular neck 12 in the area of second end face 10. In the present exemplary embodiment of the invention, tubular neck 12 encompasses a threaded stem 34 of length compensating adapter 6. Threaded stem 34 is provided with a male thread. It engages with threaded element 13 of anchor bolt 1, which has a female thread.

[0031] In addition to threaded stem 34, length compensating adapter 6 provides a shaft 33, including a threaded element 35, which receives the threaded stem and is rotatably held thereon. A threaded shaft 25 of tube clamp 4 engages with threaded element 35 of length compensating adapter 6. A distance between anchor bolt 1 and tube clamp 4 or rail 3 may thus be set by rotating shaft 33. Shaft 33 of length compensating adapter 6 thus acts as an actuating body of the screw connection, which includes shaft 33 with threaded element 35 as well as threaded stem 34 and threaded shaft 25.

[0032] Tube clamp 4 provides a receptacle 26. Rail 3 is inserted into receptacle 26 in a mounted state of the scaffolding arrangement according to the invention. Threaded shaft 25 is provided at receptacle 26. Threaded shaft 25 and receptacle 26 are rotatably fixedly or integrally connected to each other. Clip 27 is also pivotably held on receptacle 26. Clip 27 encompasses rail 3 in the mounted state. A screw closure 28 is used to fix rail 3 to tube clamp 4. It detachably connects a free end of clip 27 to receptacle 26.

[0033] In the present exemplary embodiment of the invention, rail 3 is provided with a reinforced design. It thus provides a tube jacket 23 as well as an inner tube reinforcement 24. Tube reinforcement 24 is supported on tube jacket 23 on the inside of the tube jacket. In the present case, tube reinforcement 24 is formed with a regular cross shape.

[0034] Like the tube clamp, double clamp-like couplings 30, 32 have a receptacle as well as two clips pivotably held on sides opposite the receptacle. The clips have an orientation rotated 90 degrees.

[0035] In particular, double clamp-like couplings 30, 32 are thus used to connect two tubes to each other in a crossed orientation.

[0036] The concrete specific embodiment of the scaffolding is selected as an example in the present exemplary embodiment of the invention. Of course, the scaffolding may be configured according to the requirements and adapted locally to the particular spatial and site conditions. In particular, as illustrated in the present case, the scaffolding arrangement according to the invention may comprise a modularly constructed system scaffolding, a tube/coupling scaffolding, a module scaffolding or the like.

[0037] Identical components and component functions are marked by the same reference numerals.

[0038] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
