DETAILED DESCRIPTION

A scaffolding arrangement according to the invention comprises, as essential components, an anchor bolt1designed for fixing to a building wall36, a length compensating adapter6, a tube clamp4, a rail3fixed to tube clamp4, as well as a scaffolding2and a connecting device5for connecting scaffolding2to rail3. Scaffolding2, which is illustrated in a grid-like manner by way of example inFIG.1, and which is four standard breadths wide and five standard heights high, comprises a plurality of system frames16spaced a distance apart horizontally and arranged one above the other vertically, decks17arranged between system frames16, rail posts18, which are provided between system frames16, height-adjustable threaded feet22as well as longitudinally extended toe boards20and transversely extended toe boards21. Cross-braces19are also provided to reinforce scaffolding2. Of course, the scaffolding may also have two additional elements, which are not illustrated, for example, stairs, ladders or end rails.

Rail3is used to indirectly fix scaffolding2to building wall36, which is not illustrated inFIGS.1and2. Rail3extends horizontally. Each rail3is provided at a distance of two standard scaffolding heights apart. The distance between the horizontally extending rails is thus approximately 4 meters. Rail3is formed by multiple rail elements3.1,3.2inserted into each other. Rail elements3.1,3.2inserted into each other are interconnected and fixed to each other via a ball catch.

Connecting device5is used to fix scaffolding2to rail3. Connecting device5comprises a first coupling30as well as a second coupling32. First coupling30and second coupling32are each designed in the manner of double clamps. Couplings30,32are connected via a tube29of connecting device5acting as a coupling connector. Couplings30,32are detachably and displaceably held on tube29. Due to the detachable and displaceable fixing of couplings30,32to tube29, a distance between scaffolding2and rail3may be set variably or as needed, and tolerances may be compensated for.

Rail3is fixed to building wall36via anchor bolt1, tube clamp4as well as length compensating adapter6; cf.FIGS.3and4. Anchor bolt1is designed as a multi-part anchor bolt1, including a load distribution plate7, a supporting body8and a threaded element13encompassed by supporting body8. Load distribution plate7is preferably formed from a metallic material. It is supported on building wall36via a hardening compensating compound. The compensating compound is used to level unevennesses in building wall36and ensures a contact of load distribution plate7over a wide area. Supporting body8has a first end face9facing load distribution plate7as well as a second end face10, which faces tube clamps4or scaffolding2in the mounted state. Supporting body8of anchor bolt1tapers from first end face9in the direction of second end face10. It provides a radially oriented rib11, which is used to preferably effectively absorb transverse forces transferred from the scaffolding to the anchor bolt via the rail. In addition, supporting body8provides a tubular neck12in the area of second end face10. In the present exemplary embodiment of the invention, tubular neck12encompasses a threaded stem34of length compensating adapter6. Threaded stem34is provided with a male thread. It engages with threaded element13of anchor bolt1, which has a female thread.

In addition to threaded stem34, length compensating adapter6provides a shaft33, including a threaded element35, which receives the threaded stem and is rotatably held thereon. A threaded shaft25of tube clamp4engages with threaded element35of length compensating adapter6. A distance between anchor bolt1and tube clamp4or rail3may thus be set by rotating shaft33. Shaft33of length compensating adapter6thus acts as an actuating body of the screw connection, which includes shaft33with threaded element35as well as threaded stem34and threaded shaft25.

Tube clamp4provides a receptacle26. Rail3is inserted into receptacle26in a mounted state of the scaffolding arrangement according to the invention. Threaded shaft25is provided at receptacle26. Threaded shaft25and receptacle26are rotatably fixedly or integrally connected to each other. Clip27is also pivotably held on receptacle26. Clip27encompasses rail3in the mounted state. A screw closure28is used to fix rail3to tube clamp4. It detachably connects a free end of clip27to receptacle26.

In the present exemplary embodiment of the invention, rail3is provided with a reinforced design. It thus provides a tube jacket23as well as an inner tube reinforcement24. Tube reinforcement24is supported on tube jacket23on the inside of the tube jacket. In the present case, tube reinforcement24is formed with a regular cross shape.

Like the tube clamp, double clamp-like couplings30,32have a receptacle as well as two clips pivotably held on sides opposite the receptacle. The clips have an orientation rotated 90 degrees.

In particular, double clamp-like couplings30,32are thus used to connect two tubes to each other in a crossed orientation.

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.

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

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.
