Definitions

  • the present invention relates to scaffolding. More particularly, the invention relates to safety aspects of scaffolding.
  • bamboo has been traditionally used for scaffolding.
  • bamboo scaffolding is still in use in China and Hong Kong.
  • bamboo has a number of advantages.
  • bamboo is economical and can be simply constructed without special tools.
  • bamboo scaffolding can also be constructed within a short period of time in a limited working space.
  • the most significant advantage of bamboo scaffolding is its very strong bending strength and elasticity when freshly cut.
  • the strength of bamboo decreases as time goes by because it gradually dehydrates over time. When the water content has reduced below 10% the bamboo becomes dry and cracks will appear.
  • the maximum lifespan of bamboo scaffolding members is thus relatively short, only about 12 to 18 months. Thus bamboo is considered somewhat unreliable.
  • a scaffolding structure for a building being erected, the scaffolding structure comprising: a scaffold of a substantially two dimensional inner grid interconnected with a substantially two dimensional outer grid, each of the grids being comprised of load bearing members having relatively constant strength over time under expected loading conditions of the scaffolding structure characterised in that additional bamboo members are secured on the outer grid such that the interstices defined by the load bearing members and the bamboo members of the outer grid are smaller than the interstices defined by the load bearing members of the inner grid; and an anchoring device which includes: an arm coupled to the scaffold, the arm having a longitudinal axis; and an anchoring member anchoring the device and the scaffold to the building, the anchoring member being coupled to the arm and being of an L-shape having a first leg in the form of a rod or bar which extends beyond the arm, the rod or bar being anchored into the building and a second leg is coupled to said arm.
  • the load bearing members are elongate structural members intersecting in a regular pattern to form the grids.
  • the elongate members may be coupled by right angle metal couplers at all or some of the intersections in the grid.
  • the load bearing members are steel members, preferably of tubular cross section.
  • the load bearing members may comprise fibre reinforced plastic tubes.
  • the grids are preferably constructed of load bearing members arranged at 90° to each other although other configurations are possible. Each grid may therefore have upright load bearing standards and substantially horizontal load bearing ledgers. Desirably, at least some-of the load bearing ledgers in the inner grid correspond to a respective load bearing ledger in the outer grid provided at the same height.
  • the additional bamboo members are preferably secured between the load bearing members in the outer grid.
  • the scaffolding structure is erected such that each of the distances between any two adjacent bamboo members and between any bamboo member and an adjacent load bearing member, are substantially equal.
  • the bamboo members include upright standards and horizontal ledgers with intersections between any bamboo members and other members being effected by nylon ties.
  • bamboo transoms may provide the interconnection between the inner grid and the outer grid.
  • the invention may further comprise one or more platforms on the structure, the or each platform disposed between two corresponding load bearing ledgers from the inner and outer grids which are of the same level, wherein the platform is of elongate configuration and includes a planar supporting surface and attachment means coupling the platform to the two load bearing ledgers.
  • the attachment means comprise hook portions. These hook portions may extend transversely out either side of the platform. Preferably there is a minimum of four hook portions, each extending from a respective corner of the platform.
  • the scaffolding structure of the present invention may be supported from the building being erected.
  • This building suitably includes at least one concrete slab with one or more structural beams supported from and extending outwardly from the concrete slab in a cantilevered fashion.
  • the scaffolding structure is then supported on the one or more structural beams.
  • the spacing between adjacent cantilevered structural beams will depend upon the particular application but a preferred spacing would be about 3 metres.
  • the above method may be used in conjunction with supporting brackets mounted on support columns of the building. The above method is especially appropriate where the column spacing of the building is more than 3 metres apart and the slab depth is insufficient to mount the brackets across the depth of the slab. Accordingly, the supporting brackets may be mounted to the support columns with an appropriate number of structural beams spaced between neighbouring supporting brackets mounted on respective building columns.
  • the structural beams comprise I-beams.
  • other types of structural beams are considered within the scope of the present invention including box-section beams.
  • the present invention consists in a method of constructing a scaffolding structure for a building being erected, the method including:
  • the anchoring member may be alignable such that the first leg extends substantially parallel to the longitudinal axis of the arm with the remote end of the first leg extending beyond the arm.
  • the scaffolding structure 10 illustrated in Figure 1 is a three dimensional structure.
  • the scaffolding structure 10 includes an inner two dimensional grid 12 illustrated in Figure 2 and an outer two dimensional grid 14 illustrated in Figure 3.
  • the inner grid 12 is disposed adjacent the wall of the building 15 being constructed.
  • the spacing of the inner grid 12 from the wall of the building 15 is generally about 200 mm.
  • the outer grid 14 is disposed outwardly of the scaffolding structure 10 relative to the building 15.
  • the outer grid 14 and the inner grid 12 are spaced approximately 600 to 700 mm apart. They are joined together by bamboo transoms 18 as shown in Figure 4 and Figure 1.
  • the inner grid is comprised of upright standards 20 and horizontal ledgers 22.
  • Each of the standards and ledgers are elongate steel tubular members.
  • the tubular members are joined by metal couplers (not shown).
  • the metal couplers are protected by covers to prevent contamination, particularly from concrete.
  • each of the upright standards 20 are spaced 1.5 metres apart whereas the horizontal ledgers 22 are spaced 2.25 metres apart.
  • This rectangular window created by the intersecting tubular members defines an interstice in the grid through which workers on the scaffolding structure can access the various parts of the building 15 as required. Due to the inherent strength of the steel ledgers 22 and standards 20, the interstices are comparatively large enabling easy access to the building 15 for the workers on the scaffolding structure 10.
  • the outside grid illustrated in Figure 3 comprises bamboo ledgers 25 and bamboo standards 27 in combination with steel standards 24 and steel ledgers 26.
  • the bamboo ledgers and standards are illustrated by the thin lines in Figure 3 whereas the steel ledgers 26 and standards 24 are illustrated by the thick vertical and horizontal lines of Figure 3.
  • the steel ledgers 26 and standards 24 provide the structural strength for the outer grid 14 whereas the bamboo ledgers 25 and standards 27 provide guard rails for the safety of the workman on the scaffolding structure 10.
  • the bamboo ledgers 25 and standards 27 thus increase the safety for workers on the scaffolding structure 10 without unnecessarily increasing the cost or weight of the structure.
  • the steel standards 24 in the outer grid 14 are spaced at intervals of 3 metres (in contrast to the 1.5 metre spacing of the inner grid 12).
  • the steel ledgers 26 are arranged at a vertical spacing of 2.25 metres. This corresponds to the spacing of the horizontal ledgers 22 so that the levels of the ledgers 26 in the outer grid correspond to the levels of the ledgers 22 in the inner grid.
  • the spacing of the bamboo transoms horizontally in the scaffolding structure 10 in line with the ledgers 26, 22 corresponds to the spacing of the bamboo standards 27 in the outer grid.
  • the bamboo standards 27 are arranged at spacings of 0.75 metres which allows for three at equal spacing from and between adjacent steel standards 24.
  • the bamboo ledgers 25 are arranged at equal spacing of 0.75 metres from and between adjacent steel ledgers 26. Given that the steel ledgers are spaced 2.25 metres, apart this enables two bamboo ledgers 25 at equal spacing therebetween.
  • the intersecting steel elongate members are joined by metal couplers.
  • the intersecting bamboo members are joined by nylon tie.
  • Figure 4 also illustrates the arrangement of netting 28 on the outer grid of the scaffolding structure. This prevents materials or tools dropping outside the scaffolding structure.
  • the netting 28 should be securely attached to the scaffolding structure by nylon tics or metal wire as illustrated.
  • FIG 6a shows diagrammatically only, the main structural components of the scaffolding structure 10.
  • Each of the steel standards 20, 24 is about 6 metres long.
  • Each level of the scaffolding structure 10 is referred to as a "zone” and is 24 metres in height as indicated in Figure 6a.
  • each zone is made up of 4 x 6 metre lengths of the steel standards 20, 24.
  • the region between adjacent steel standards 20, 24 in each zone is referred to as a "bay”.
  • the height of each bay is defined by the vertical distance between support brackets 30.
  • the support brackets disposed at vertical intervals corresponding to the length of four steel standards 20, 24, the height of each bay is thus 24 metres.
  • the vertical spacing of the brackets will naturally depend upon the weight of the scaffold and the expected loading.
  • the configuration of the support bracket 30 is illustrated schematically in Figure 15a.
  • the steel standards 20, 24 of the scaffolding structure 10 fit into suitable recesses (not shown) on one arm of the bracket.
  • the support bracket 30 is constructed from angle iron configured in the shape of a right angle isosceles triangle having side lengths of 900 mm.
  • the angle iron might be 80x80x8 angle grade 43 depending on the particular application.
  • One side of the support bracket 30 is secured to the wall of the concrete building, preferably at an upright support column of the building 15.
  • An array of supporting brackets 30 thus provides support for the scaffolding structure 10 at the base thereof and at intervening levels of the scaffolding structure.
  • a temporary bamboo structure may be first erected. Once the first layer of steel brackets 30 has been installed, the temporary bamboo structure may be transformed to be components of the scaffolding structure.
  • Figure 15b illustrates an alternative form of support bracket 30b. It can be seen from Figure 6a that the appropriate vertical spacing for the brackets is 24m. However, by using the higher strength brackets illustrated in Figure 15b together with closer spacing of the anchoring devices (see Figures 9, 10a and 10b), the bracket spacing can be increased to 30 m as shown in Figure 6b.
  • Figure 6b also illustrates that a bracket 30b of one level should be offset by an appropriate amount (80mm) in relation to the bracket 30b on an adjacent upper or lower level. This enables the steel standards to be overlapped (preferably by about 3m) and clamped together in the manner illustrated.
  • the clamps 30c are arranged at a spacing of about 750mm.
  • the building columns may be located too far apart for effective securement of adjacent supporting brackets 30.
  • an alternative supporting arrangement for the scaffolding structure will be required as illustrated in Figure 7.
  • Figure 7 illustrates adjacent columns 40 of the building 15 with a slab 42 extending therebetween.
  • Two supporting brackets 30 are bolted by bolts 46 to respective columns 40 as illustrated.
  • these supporting brackets 30 exceed the maximum permissible spacing therebetween for properly supporting the scaffolding structure 10. Therefore, cantilevered I-beams 44 are bolted to the slab to extend outwardly beyond the slab 42 as illustrated in Figure 8.
  • the inner grid 12 and the outer grid 14 are supported on the I-beam 44 as illustrated in Figure 8, provided that the outer grid 14 is a minimum of 200 mm from the cantilevered end of the I-beam 44 and the inner grid 12 is a minimum of 200 mm from the end of the slab.
  • the I-beams 44 are temporary and may be removed once the scaffolding has been disassembled.
  • FIG 9 illustrates one method of anchoring the scaffolding structure 10 to the building 15.
  • the anchoring is achieved by way of an anchoring device 50 as shown in Figure 9.
  • the anchoring device 50 is illustrated more clearly in Figure 10a.
  • the anchoring device 50 comprises a relatively short arm of metal tube of approximately 1 metre in length having an outside diameter of 48.6 mm.
  • an anchoring plate 54 adapted to be bolted to the concrete building 15 as shown in Figure 9.
  • the metal tube 52 is secured to the upright standards of the inner grid 12 and the outer grid 14 by way of metal right-angle couplers (see Figure 9).
  • the anchoring plate 54 also provides an eyelet 56 for attachment of a steel cable 58.
  • the other end of the steel cable 58 of R6 steel wire is provided with a coupling 59 for securement to a member of the outer grid 14 as shown in Figure 9.
  • a coupling 59 for securement to a member of the outer grid 14 as shown in Figure 9.
  • the anchoring method illustrated in Figure 9 serves to anchor both the inner grid 12 and the outer grid 14 to the building given that only bamboo transoms 18 are provided between the two grids.
  • the anchoring method may serve as a backup in case of any failure of the brackets 30.
  • FIG 10b illustrates an alternative anchoring device 50b.
  • the anchoring device 50b includes a short arm 52b of about 1m in length. At one end of the arm, a through-aperture 50d is provided into which an anchoring member 50c in the form of an L-shaped rod is received.
  • the anchoring member 50c has a first leg having a free end which, in the configuration shown in the drawing, extends past the end of the arm. The free end of the first leg is threaded to enable the anchoring member to be secured into the structure of the building being erected.
  • the small footprint of the first leg onto the building enables the first leg to be secured almost anywhere, thereby allowing greater flexibility in locating the anchoring device.
  • the anchoring member 50c may be cast into position or alternatively secured to the concrete structure of the building 15 after the concrete has set.
  • the threaded end may extend into the concrete about 750mm.
  • the anchoring member 50c also includes a second leg which is received in the through- aperture 50d.
  • the second leg also has a threaded free end. This threaded free end receives a nut (not shown) to retain the second leg within the aperture.
  • the length of the second leg is such that the arm 52b can slide along the second leg, hence increasing the flexibility in locating the first leg at an appropriate location on the building 15.
  • frequent use of the anchoring devices reduces the demand for support brackets. Desirably, the vertical spacing should not exceed 2.25m and the horizontal spacing should not exceed 3m. From a comparison of Figures 6a and 6b, it can be seen that the vertical spacing between brackets can be increased from 24m to 30m. This is achieved with frequent use of the anchoring devices 50b and the modified form of brackets 30b.
  • FIG 11 illustrates appropriate bracing 60 for the scaffolding structure 10.
  • the outside grid 14 of the scaffolding structure 10 is illustrated diagrammatically by the spaced upright steel standards 24.
  • diagonal cross bracing is typically arranged at an angle of 45- 60° plus or minus 5°.
  • Figure 12 illustrates a detail of the outer grid 14 with the dotted line 70 illustrating the location of an intended opening to be formed in the outer grid 14.
  • An opening 70 such as that illustrated might be required to load materials onto the site.
  • Figure 13 illustrates the detail of the outside grid 14 with the opening cut 70.
  • the bamboo and steel members have been cut as illustrated.
  • additional bracing members 72 are installed. These extend diagonally as shown. Additionally, warning signs are installed to notify workers on the scaffolding structure of potential danger.
  • the catch fan 80 comprises a catchment surface 82 extending upwardly and outwardly from the scaffolding structure 10.
  • the catchment surface 82 is defined by spaced metal tubes 84 extending upwardly and outwardly from the outer grid 14 with a canvas-like fire resistant material extending over the metal support tubes 84.
  • the upper and outer ends of the metal support tubes 84 are supported by further metal tubes 86.
  • Each metal tube 86 is joined to the end of one of the metal tubes 84 and extends from that end upwardly and inwardly towards the outer grid 14.
  • the catchment surface 82 is arranged at an angle of 45° from the horizontal but is adjustable with adjustment of the further metal tubes 86.
  • the catchment surface 82 is provided to catch materials falling off the building 15 or scaffolding structure 10 for easy collection of debris and removal.
  • Catch fans 80 are generally provided at each ten storey interval. However, individual contractors may install the catch fans 80 to suit the requirements of a particular building site.
  • protective layers 90 are disposed at regular intervals, preferably immediately above the supporting brackets ie every ten storeys.
  • the projective layers 90 provide access for workers as well as protect the workers from falling. Additionally, the protective layers 90 protect the workers from falling debris.
  • Each protective layer 90 comprises a layer of horizontally arranged bamboo members 92 extending between adjacent transoms 18. The spacing of the bamboo members should not exceed 200mm.
  • the bamboo members 92 can be above or below the transoms 18. These bamboo members provide a buffer effect in case heavy objects fall from above.
  • zinc sheet 94 is laid down. The zinc sheet may be formed with upturned edges 94a of about 100mm in height.
  • a bamboo ledger (not shown) fastened on top of the zinc sheet prevents the sheet from blowing away.
