Definitions

  • This invention is in the field of scaffolding as is typically used to provide access and support structures around buildings, erections, towers and the like.
  • Such scaffolding is generally made of tubular longitudinal lengths, which are connected together by various fixing methods.
  • One well known method is known as the Cuplok (Trade Mark) method which inter-links tubular members without the use of nuts, bolts or wedges.
  • the locking device is formed by two cups, a fixed lower cup which is welded on the under side of the connection of two tubes and a sliding upper cup.
  • the tubes are provided with forged blade ends which are shaped in a concave manner with a radius which corresponds to the outer radius of the tubes .
  • the blade end of the tubes are located into the lower cup fixed on a second tube and the upper cup is then moved down and rotated to secure the component in place.
  • the upper cup may be tightened by a hammer blow to give a positive and rigid connection. 2
  • the Cuplok scaffolding system is known and accepted internationally and considered to be a fast and safe scaffolding fixing system.
  • the blade ends are replaced by a pin and wedge system.
  • the pin is located in an aperture provided externally on an adjacent tube to be connected and the wedge is then hammered into the aperture to locate the pins securely.
  • the tubular components commonly found in scaffolding are provided with irregular fixing arrangements at each end thereof. While these arrangements enable the connection of the tubing, they also cause a disadvantage. Specifically, as the tubing is relatively long and thin, occasionally it may become damaged or bent in use. The existence of the irregular arrangements at each end of the tubing render it unsafe to run the tubing through straightening machines or apparatus. Often, bent tubing is discarded for scrap.
  • An object of the present invention is to provide a means for reclaiming all or part of bent scaffold tubing.
  • the present invention also finds application in the construction of scaffolding gates.
  • such gates have been mounted on the scaffolding using a caster wheel system to enable the gates to slide.
  • a tube is provided in the scaffold structure that functions as a runner upon which the gates are hung and slide. 3
  • sliding scaffolding gates are not particularly safe or desirable.
  • the gates should be suitable for easy access and adapted to be simple to open and close by workmen who may be carrying tools or building materials. Sliding gates are generally not adapted to close automatically, nor are they easy to provide with a catching mechanism that maintains them in a closed position for safety reasons and yet are easy to open when needed.
  • a further object of the present invention is to provide improved scaffolding gates and more particularly an improved means for mounting such gates.
  • mounting apparatus for mounting gates in association with scaffolding, the mounting apparatus comprising means for co-operating with a known scaffolding fixing system, a hinge and means for attachment to a gate.
  • the means for co-operating with a scaffolding fixing system comprises a forged blade end suitable for use in the Cuplok system.
  • the means for co-operating with a scaffolding fixing system may comprise a pin and wedge member suitable for use in the Kwikstage system. Other systems may be employed.
  • the hinge is formed by a pin which extends vertically through an aperture cut into a link member formed between the means for co-operating with the scaffolding fixing system and the gate attachment means.
  • the pin is fixed in the aperture by lugs or washers welded on the pin on each 4 side of the aperture, yet the pin being free to rotate in the aperture such that it may function as a hinge.
  • a sleeve or sheath may be provided in the aperture in the link member.
  • the gate attachment means comprises a weld joining the pin to the gate.
  • a method of reclaiming bent or otherwise damaged tubular components used for scaffolding comprising the steps of:
  • the method may further include straightening the relatively long portion of the tubular component after truncating the end thereof.
  • the above method may be repeated at the opposite end of the tubular component.
  • the method may specifically include use of the end portion of the tubular component in the mounting of gates for use in association with a scaffolding structure. 5
  • Figure 1 shows a new tubular component having welded steel blades at each end thereof
  • Figure 2 shows a truncated end portion of the tubular component shown in Figure 1 which has been adapted for use in an alternative manner according to the invention
  • Figure 3a and Figure 3b show, respectively, elevation and plan views of the truncated end member of Figure 2 used in the mounting of a scaffolding gate;
  • Figure 4a and Figure 4b show, respectively, elevation and plan views of an alternative embodiment of the invention.

  • a tubular component used in scaffolding is generally depicted at 1.
  • the component comprises a longitudinal tube 2 which is provided with forged blades 3 at each end thereof.
  • the blades 3 are welded to the tube 2 in a substantially orthogonal relationship and are provided with a concave profile which is sized to partially circumnavigate an additional tubular component (not shown) to which the tubular component 1 is to be connected.
  • the invention provides for cutting or truncating the tubular component 1 substantially toward and end thereof so as to provide a relatively long portion of the tubular component 1 (not shown) and an end portion generally depicted at 4 in Figure 2.
  • the end portion 4 has a short tubular portion 5 and a forged blade end 3.
  • the end portion 4 has been modified by providing same with a through-bore or aperture 6 which runs substantially parallel to the longer axis of the blade end 3.
  • FIG. 3 A use of the modified end portion 4 is shown in Figure 3.
  • a weldmesh gate 7 is mounted on the scaffolding by mounting apparatus comprising the modified end portion 4 and a pin 8.
  • the pin 8 is bent to form a right angle and has one end 8a welded to the gate frame 7a.
  • the free end 8b of the pin is positioned in the aperture 6.
  • the pin 8 is secured in the 7 aperture 6 by the use of two washers 9 welded to the pin 8 on either side of the aperture 6.
  • the blade end 3 on the modified end portion 4 is fixed to adjacent scaffolding, and more particularly, a vertical tubular component 10 using the normal Cuplok fixing.
  • a similar or identical mounting means may be employed and typically two such mounting apparatus are used for each gate.
