Abstract
The invention relates to a vertical scaffold tube having attached thereto at least one holding means, into which horizontal and/or diagonal scaffold tubes can suspended each of the scaffold tubes having a reinforcement in that region where the holding means is attached to the vertical scaffold tube.
Description
A Vertical Scaffold Tube Having Improved Load-Bearing Capacity The invention relates to a vertical scaffold tube having attached thereto at least one holding means, into which horizontal and/or diagonal scaffold tubes can be sus-pended.
Vertical scaffold tubes having attached holding means for horizontal and/or diagonal scaffold tubes find various uses in scaffolding. In order to join the horizontal and/or diagonal scaffold tubes with the vertical scaffold tubes, the bearing heads of the horizontal and/or diagonal scaffold tubes are suspended in the holding means of the vertical scaffold tubes and then clamped using a wedge. Such clamping causes the contact surface of the bearing head to be pressed tightly against the vertical scaffold tube, thereby forming a frictional and positive connection between the bearing head and the scaffold tube which, in an interaction with the hold-ing means, effects a transfer of all the forces and momentums from the horizontal and/or diagonal scaffold tubes to the vertical scaffold tube. Accordingly, tension peaks occur in the vertical scaffold tube around the holding means, which frequently give rise to impressions in the vertical scaffold tube at these positions, or to some other type of damage. To avoid such damages, the wall thickness of the scaffold tubes has been increased, with the consequence that these construc-tion elements have higher weight and thus, poorer handling.
The object is therefore to provide a scaffold tube having improved load-bearing capacity.
According to the invention, said object is accom-plish~sd by providing a vertical scaffold tube having attached thereto at least one holding means, into which horizontal and/or diagonal scaffold tubes can be suspended, each of the scaffold tubes having a reinforcement in that region where the r~olding means is attached to the vertical scaffold tube.
In the meaning of the invention, a vertical scaffold tube is any vertical scaffold tube of any cross-section and any dimensions that is known to a person skilled in the art.
However, the scaffold tube preferably has a circular cross-secti.on, the outer diameter of which being 48 mm.
These vertical scaffold tubes have attached thereto at least one arbitrary holding means known to the artisan, such as those disclosed in US 5,605,204, particularly Fig-ure 2; DE 24 49 124, particularly Figures la and lb; DE-OS
196 02 737, particularly Figure 1; EP 0,289,825, particularly Figure 3, and in Applicant's parallel application having the internal reference PH 8061, particularly Figures 1 and 2.
According to the invention, each scaffold tube must have one reinforcement in the region of said holding means.
In a preferred way, said reinforcement is achieved by a local enlargement of tie wall thickness of the vertical scaffold tube. These enlarged wall thicknesses have prefera-bly been rolled in.the sheet metal which is used to produce the vertical scaffold tubes. The enlarged wall thickness may bulge inwardly and/or outwardly. The wall thickness in the region of the holding means is preferably enlarged by about 50-150%. The length of the wall thickness enlargement prefer-ably is 1-3 times the scaffold tube diameter. Attachment of the holding means is effected in the reinforced area, prefer-ably in the center thereof, and preferably by welding.

According to the invention, each scaffold tube must have one reinforcement in the region of said holding means.
In a preferred way, said reinforcement is achieved by a local enlargement of tie wall thickness of the vertical scaffold tube. These enlarged wall thicknesses have prefera-bly been rolled in.the sheet metal which is used to produce the vertical scaffold tubes. The enlarged wall thickness may bulge inwardly and/or outwardly. The wall thickness in the region of the holding means is preferably enlarged by about 50-150%. The length of the wall thickness enlargement prefer-ably is 1-3 times the scaffold tube diameter. Attachment of the holding means is effected in the reinforced area, prefer-ably in the center thereof, and preferably by welding.
In another preferred embodiment, reinforcement is achi~wed using a sleeve which is pushed over the outside of the vertical scaffold tube and then fastened by shrinking, pressing or welding. The holding means is then attached to the ;sleeve, preferably in the center thereof, and preferably by welding. It is also preferred to produce the sleeve and the holding means as one single part which then is pushed over the vertical scaffold tube and affixed to the scaffold tube in the manner described above. The wall thickness of the slee~~e preferably is 0.5-1.5 times the wall thickness of the vertical scaffold tube. The length of the sleeve preferably is 1~-2 times the scaffold tube diameter.
It is also preferred to accomplish reinforcement using a bushing in the interior of the scaffold tube. The bush:~ng can be fitted in by shrinking or pressing. In a pre-ferred embodiment, the bushing is designed as a split tubular pin 'which is introduced in the vertical scaffold tube and then released at the appropriate position. The wall thickness of the bushing preferably is 0.5-1.5 times the wall thickness of the vertical scaffold tube. The length of the bushing preft:rably is 1-2 times the scaffold tube diameter.
In another preferred embodiment, reinforcement is accomplished by a ring arranged above each holding means. The spacing between the ring and the holding means preferably is 0.2-:1.0 times the tube diameter. The wall thickness prefera-bly _'~s 0.5-1.5 times the wall thickness of the vertical scaf-fold tube. The length of the ring preferably is 0.1-1.0 times the :scaffold tube diameter.
It is also preferred to attach a ring both above and below the holding means. The spacing between the rings and the holding means preferably is 0.2-1.0 times the tube diame-ter. The wall thickness of the rings preferably is 0.5-1.5 timef; the wall thickness of the vertical scaffold tube. The lengi:h of the rings preferably is 0.1-1.0 times the scaffold tube diameter. It is preferred to arrange the rings symmetri-call~~ with respect to the holding means.
The vertical scaffold tube according to the invention has ei higher load-bearing capacity compared to a prior art vertical scaffold tube. The reinforcements can be mounted easily, and retrofitting is possible in the case of bushings or split tubular pins, for example. Owing to the local rein-forcement, the overall wall thickness of the vertical scaf-fold tube can be reduced, resulting in a lower weight of the vertical scaffold tube compared to prior art scaffold tubes.
The use of a wall thickness lower than a nominal 3.2 mm is possible without loss of load-bearing capacity of the verti-cal scaffold tube.
