Definitions

  • This invention relates to scaffold clamps suitable for use a part of a scaffolding system.
  • this invention relates to scaffold clamps comprising spacer wings having carefully selected dimensions that permit the mutually orthogonal connection of scaffold tubes in a tube-on-tube and/or in a clamp-on-clamp configuration.
  • the invention may facilitate bracing a scaffold assembly to a wall using the same transom tubes that are used to support scaffold boards.
  • a further possible advantage of the invention is the ability for form a "birds nest" intersection of vertical and horizontal scaffold tubes in a tube-on-tube configuration.
  • Scaffolding is a system of tubes, connectors, boards, ladders and other items that can be connected together to form a framework around, for example, a building. Scaffolding can be used in various ways, such as: to provide elevated walkways around and/or external access to, a building, for example so that workers can make repairs to, or construct, the building; a (or part of) temporary and/or free-standing construction, for example to support display screens at live events; and to provide temporary structural support to a building during remedial works.
  • the applications of scaffolding are not limited to the foregoing examples, which are merely exemplary.
  • scaffold tubes can be used vertically to provide support for other scaffold tubes arranged horizontally, which can be topped by boards forming walkways.
  • the same tubes can be used to form guardrails, cantilevered platforms, and mountings for derricks and so on.
  • scaffold boards can be used as parts of walkways, toe boards, walls, etc.. It will be appreciated that the range of configurations is almost limitless. When erecting a scaffold, due care and attention needs to be paid to safety and structural integrity.
  • scaffold tubes are correctly aligned, both relative to the horizontal and vertical, as well as relative to one another.
  • Vertical scaffold tubes need to be plumb to ensure that weight is correctly transmitted through them and to minimise bowing or buckling that can occur in non-vertical tubes.
  • horizontal tubes need to be level to ensure that walkways, guard rails etc. are not canted.
  • scaffold clamps which comprise a pair of interconnected C-shaped claws that engage with respective scaffold tubes, and a corresponding set of clamp portions that clamp each of the scaffold tubes firmly into their respective claws.
  • Scaffold clamps of this general type are very well-known and do need further explanation here. Where a scaffold is assembled using only one type of scaffold clamp, in all likelihood, the spacings between adjacent or overlapping tubes will be the same, thus ensuring that sets of scaffold tubes can be correctly aligned, that is to say, the horizontal tubes will lie in one plane, and the vertical tubes will lie in another plane.
  • This invention aims to provide a solution to one or more of the above problems and/or to provide an improved/alternative scaffold clamp.
  • a scaffold clamp comprising first and second generally claw portions, and a respective set of releasable clamping portions associated with each of the claw portions for securing, in use, a respective scaffold tube between the claw portion and its respective clamp portion, wherein the scaffold clamp further comprises a spacer interposed between the generally claw portions.
  • Another aspect of the invention provides a scaffold assembly comprising pair of scaffold tubes interconnected by a scaffold clamp as described herein.
  • the scaffold assembly comprises at least one vertical scaffold tube connected to at least one first horizontal scaffold tube, the first horizontal scaffold tube forming one part of a ladder beam, and wherein a second horizontal scaffold tube forming another part of the ladder beam is affixed to the vertical scaffold tube by clamp, wherein the spacer of the scaffold clamp is dimensioned to bring the first and second horizontal scaffold tubed into vertical alignment.
  • the scaffold assembly comprises a second horizontal scaffold tube affixed to the vertical scaffold tube by a clamping portion forming part of a transom unit.
  • the scaffold assembly may comprise a further vertical scaffold tube affixed to the ladder beam by way of a scaffold clamp as described herein.
  • the dimensions of the spacer of the scaffold clamp are selected to bring the vertical scaffold tube and the further vertical scaffold tube into alignment.

  • Another aspect of the invention provides a scaffold assembly substantially as hereinbefore described, with reference to, and as illustrated in, Figures 4 to 9 of the accompanying drawings.
  • the claw portions are generally C-shaped, i.e. adapted to accept/receive a scaffold tube.
  • a spacer interposed between the claw portions means that the centres of the generally C-shaped claw portions (and thus, in use, the centres of the connected scaffold tubes) can be/are maintained at a desired spacing.
  • the desired spacing is different to that of a standard scaffold clamp.
  • the desired spacing is greater than that of a standard scaffold clamp, i.e. a known scaffold clamp that may be used on another part of a scaffold assembly comprising scaffold clamps in accordance with the invention.
  • the spacer comprises a (generally cuboidal) projection formed integrally with each of the claw portions.
  • the projections can be permanently connected, for example, by welding, to one another to form the spacer between the inner surfaces of the claw portions to maintain them in a fixed, spaced-apart configuration.
  • the projection can be integrally formed with just one of the claw portions, and can be permanently connected, for example, by welding, to the claw portion of the other part of the connector.
  • use of the scaffold clamp of the invention usefully enables scaffold tubes to be connected between scaffold systems of different types: the spacer avoiding the need for further scaffold tubes or components to be inclined or offset where the planes of the components of the different scaffolding systems are not coplanar.
  • the spacer is fixed, and provides a rigid connection between the claw portions of the scaffold clamp.
  • the claw portions can be arranged about the spacer in the same orientation (i.e. to interconnect a pair of parallel scaffold tubes); at right angles (i.e. to interconnect a pair of perpendicular scaffold tubes); or at any desired angle, such as 45-degrees, 30-degrees, 60-degrees etc.
  • the spacer comprises a swivel, which provides a rotatable connection between the claw portions of the scaffold clamp.
  • a swivel which provides a rotatable connection between the claw portions of the scaffold clamp.
  • the swivel may be lockable at a desired relative claw orientation, for example, using a spline shaft or grub screw.
  • the dimensions of the spacer are selected to ensure that interconnected tubes from different scaffolding systems are coplanar or parallel.
  • the spacer is configured to provide a substantially 38mm (i.e. 38mm +/- 0.5mm, +/- 1mm, +/- 1.5mm, +/- 2mm, or +/- manufacturing tolerances) spacing between the outer diameters of overlapping; or in one specific embodiment, a substantially 86.3mm spacing between the centres of overlapping 48.3mm OD scaffold tubes.
  • the aforementioned dimensions render the scaffold clamp of the invention ideally suited for use with scaffold assemblies incorporating eadylok or readylock-type prefabricated transom units.
  • the scaffold clamp is suitably manufactured from strong, tough, durable materials, such steel, galvanised steel and stainless steel.
  • the claw portions and their respective releasable clamping portions are together shaped and dimensioned to receive, in use, standardised scaffold tubes, such as 48.3mm OD scaffold tubes.
  • the releasable clamping portions are suitably detachably and/or releasable affixed to the claw portions by releasable locking means, such as by bolts and nuts, a cam lock device or similar.
  • the scaffold clamp conforms to EN74 (and/or any of its variants).
  • the scaffold clamp is suitably sufficiently load-bearing to enable it to conform to EN74, that is to say, having sufficient resistance to slippage, bending moments and cruciform loading to conform to the structural (strength, gripping and flexure) requirements of, for example, EN74-1 (2005).

  • the upper horizontal tube 20 of the ladder beam 16 engages with a clamping part 24 of a transom unit 25.
  • the clamping part 24 is formed from a sheet of steel bent into a generally M-shape when viewed from above (as in Figure 2), the limbs 28 of which comprise C-shaped cut outs when viewed from the side (as in Figure 3) for receiving the upper horizontal tube 20 of the ladder beam 16, and the interconnecting part 30 abuts the vertical scaffold tube 12.
  • a clamp portion 32 firmly grips the vertical tube 12 to the interconnecting part 30 of the clamping part 24 to form a rigid connection.
  • the transom unit 25 comprises a horizontal tube 26 that is oriented perpendicular to the ladder beam 16, which horizontal tube 26 supports a floor surface (not shown) of a walkway.

Even modest inclinations can significantly affect the structural characteristic of the ladder beam. Further, if a further vertical scaffold tube (not shown) were to be dropped from the upper horizontal tube 20 of the ladder beam 16, it is readily apparent that this further vertical scaffold tube (not shown) would be inwardly offset relative to the aforementioned vertical scaffold tube 12.

  • the scaffold clamp 500 is able to better grip a scaffold tube, thereby increasing its resistance to slippage.
  • the scaffold clamp's resistance to bending moments is greatly improved due to the increase in height of the load-bearing area 502.
  • the scaffold clamp's resistance to cruciform loading is greatly increased, compared with known scaffold clamps, due to the increase in width of the load-bearing area 502 in contact with the scaffold tube.
  • the provision of the wings 510 enables the scaffold clamp 500 to conform to the structural (strength, gripping and flexure) requirements of EN74-1 (2005). It will be noted from Figures 10 to 18 of the drawings, that the wings 510 each have a pair of parallel, planar end surfaces 212 (one at either side).
  • the end surfaces, in the illustrated embodiments of Figures 10 to 18 are 58.5mm apart, but this dimension is purposively selected such that when the end surface 212 of one clamp 500 abuts the releasable clamping portion 54 part of an adjacent clamp 500, as shown in Figure 12 of the drawings, this creates a clamp-on-clamp connection with a precise "tube-on-tube” placement also (i.e. the underside of one scaffold tube 512 rests upon the upper side of another scaffold tube 514).
  • the aforementioned 58.5mm dimension is not fixed, but is rather a function of certain other dimensions of the clamp (i.e. the width of the clamping portions 54) as well as the outer diameter of the scaffold tubes.
  • the wings 510 and their carefully selected dimensions, enables a mutually orthogonal connection of scaffold tubes 12, 512, 514, as shown in Figures 13 and 14 of the drawings.
  • the main advantage of this is that it is possible to brace a scaffold assembly 100 (such as that shown in Figure 9 of the drawings) to a wall, with its transom tubes 512 resting directly on top of the cross-members 514.
  • This configuration which is not possible with existing scaffold clamps, enables the transom tubes 512 to be used to support scaffold boards (not shown) as well as to provide a structural connection to a wall.
  • a similar configuration when used with known scaffold clamps, requires a first transom tube to be used to support the scaffold boards, and a further, offset transom tube, to brace the scaffold assembly 100 to the wall.
  • a clamp-on-clamp and a tube-on- tube configuration as is the case with the invention, it becomes possible to brace a scaffold assembly to a wall using the same transom tubes that are used to support the scaffold boards.
  • a further advantage of the scaffold clamps 500 in accordance with the invention is that they permit the formation of a "birds nest" intersection of vertical 12 and horizontal 512, 514 scaffold tubes, also in a tube-on-tube configuration.
  • This is shown in Figures 15 to 18 of the drawings, in which (compared with Figures 13 and 14 of the drawings) the tubes are no longer mutually orthogonal, but rather the transom tube 512 is rotated through 30° or 60° (or indeed any other desired angle).
  • the wings 510 are configured to extend around their respective scaffold tubes to such an extent that the aforementioned "birds nest" configuration can be obtained whilst maintaining the tube-on-tube configuration.
