Definitions

  • THIS INVENTION relates to improvements to scaffolding and in particular to an improved scaffolding gantry suitable particularly for erection on a footpath say to allow pedestrian passage thereunder but to protect pedestrians from possible falling debris associated with building construction or demolition.
  • scaffolding gantries are formed from a plurality of scaffolding elements including a number of upright pipe members and a plurality of ledgers which are interconnected in such a fashion as to form on a footpath a passageway or tunnel through which pedestrians may pass.
  • the conventional type of scaffolding gantry as above has a number of disadvantages.
  • the footpath area upon which the scaffolding is to be erected has to be hired form the relevant Local Authority from the commencement of the erection of the gantry and as erection often takes up to four weeks, four weeks' hire of the footpath is required before erection or demolition of a building can commence.
  • labour costs are particularly high and the scaffolding gantry if not satisfactory to the relevant authorities, may require to be disassembled and re-erected after inspection.
  • Normally scaffolding gantries of the above form are assembled from a plurality of scaffolding components which are simply dumped on site and after completion of a buildingwork, those components are required to be disassembled, repaired if necessary and delivered back to the hirer thereof and costs are often associated with repair of such components or replacement thereof in the event of missing components.
  • the present invention aims to overcome or alleviate at least some of the above disadvantages by providing an improved scaffold gantry assembly and in particular a gantry assembly of modular form which may be arranged on site rapidly and efficiently and which therefore requires minimum costs for assembly.
  • the present invention also aims to provide a gantry which is safe in use and constructed of a minimum number of components so as to avoid losses associated with the conventional type of gantry.
  • the gantry assembly of the present invention comprises a plurality of gantry modules each being preferably of a rectangular form and comprising a plurality of upstanding support members or legs and a roof assembly secured to and supported by the upstanding legs.
  • a plurality of such gantry modules are arranged in end to end relationship with suitable means provided to interconnect the adjacent legs.
  • each leg is provided with a foot assembly which may be adjusted to suit varying footpath undulations or heights.
  • the upstanding members are foldable to enable modules to be stacked for transport.
  • a scaffolding module 10 according to a preferred form of the present invention.
  • the module in this instance is of generally rectangular form and includes four upright preferably hollow rectangular cross sectioned support members 11 at the corners thereof which support at their upper end a deck framework 12 which is covered by a sheeting material 13 such as steel sheet or the like.
  • a sheeting material 13 such as steel sheet or the like.
  • suitable bracing 14 is provided at the upper ends of the support members 11 to provide stability to the module 10.
  • the operative rear wall of the module is also closed in by sheeting 15 such as steel sheeting which may be supported by a central bracing member 16 extending between the rear upstanding support members 11.
  • Each upstanding support member 11 is provided at its lower end with an adjustable foot assembly 17 each of which may be adjusted to support the module 10 in a required attitude and which are preferably arranged to compensate for variations in or undulations in the surface such as a footpath surface upon which the modules are to be supported.
  • each foot assembly 17 may be in the form shown in Figs. 4 and 5 and include a first hollow member 18 telescopically receivable within the lower end of the support member 11 and provided with a plurality of spaced apertures 19 therein which may be aligned with a pair of apertures in the opposite sides of the support member 11 so that a locking pin or member 20 may be passed therethrough so that the hollow member 18 is maintained in a fixed position relative to the end of support member 11.
  • This adjustment may be varied by removing the pin 20 and repositioning the hollow member 18 until a further pair of its apertures 19 are aligned with the apertures 20 of the support member 11. This therefor provides for a course adjustment of the length of the support member 11.
  • the lower end of the hollow member 18 is provided with an end cap or plate 21 provided with an aperture 22 thereon to receive therethrough the threaded shank 23 of the support foot 24 in the manner illustrated.
  • Plate 21 may be provided with a plurality of drainage holes.
  • Fine adjustment of the foot 24 is achieved by means of a nut 25 threadely engaged with the shank 23 and normally in abutment with the end cap 21.
  • a nut 25 threadely engaged with the shank 23 and normally in abutment with the end cap 21.
  • Suitable abutment of the nut 25 with the cap 21 is maintained by means of a spring 26 surrounding the threaded shank 23 internally of the hollow member and interposed between the end cap 21 and an end plate 26 secured to the end of the threaded shank 18.
  • the opposite end of the foot 24 is provided with a universal joint so that the foot may adopt any position to cater for variations in the underlying support surface.
  • the universal joint comprises an eye 27 at the end of the threaded shank received within a hollow housing 28 secured to a planar mounting foot 29.
  • the hollow housing 28 is provided at its opposite sides with respective cut out portions 30 which are so sized and positioned as to captively hold the eye 27 within the hollow housing 28.
  • the above described arrangement also permits easy cleaning of the housing 28 after use.
  • This joint permits a sufficient degree of universal movement to cater for most variations encountered in the support surface for the gantry.
  • other suitable pivotal foot assemblies 17 may be employed for the support members such as a universal ball type joint as shown in Fig. 6.
  • the invention also provides a plurality of clamp assemblies which may be used to clamp together respective upright support members 11 of adjacent gantries.
  • a suitable clamp assembly 31 for this purpose is shown in Fig. 7 and comprises a pair of hinged parts 32 and 33, one part 32 being of relatively planar form, the other part defining an elongated recess 34 which in use neatly receives a pair of support members 11.
  • the respective parts may then be simply held together by bolting.
  • the support members may be simply bolted together by means of bolts passing through aligned holes therein.
  • clamps 31 ⁇ may also be provided with means for engaging and retaining side rails 32 for the gantries and a suitable form for such retaining means is shown in Figures 8 to 10.
  • Normally side rails 32 are attached to a gantry 10 intermediate the ends of the upstanding support members 11 for pedestrian safety purposes and as used in the present instance are preferably of C shape cross-section form.
  • the means for engaging and retaining the side rails in this instance are operative to clamp the free flange ends 33 of the C-shaped rails to the upstands 11 and for this purpose the retaining means comprise a pair of jaws 44 pivotably mounted on a support plate 35 forming part of the support member clamp 31 ⁇ and being pivotal from an engaged position shown in Figure 8 to a disengaged position whereby the side rails 32 may be detached.
  • means are provided to urge the jaws 44 to an operative retaining attitude and in this instance such means comprise a bolt 36 which is passed through apertures 37 formed in ears 38 comprising extensions of the jaws.
  • the bolt 36 may simply be tightened to pivot the ears 38 towards each other and cause corresponding opposite pivotal movement of the jaws 44 to a rail retaining and clamping attitude.
  • one of the ears may be provided with a threaded stud which is passed through an aperture 37 in the other ear to be engaged by a nut.
  • support plate 35 has welded thereto a tubular section 43 which in use aligns with through apertures 37.
  • ears 38 are clamped by bolt 36 in abutting relationship with tubular section 43.
  • tubular section 43 the portion of jaws 44 contacting the free flange ends 33 of the C-shaped rails may be angled towards and in some cases past the edge of upstand 11 when the ears 38 are in operative abutment with tubular section 43 to provide additional frictional holding of the C-channel side-rails 32 when operatively engaged.
  • the gantry modules may also be provided with detachable top rails 39 which serve as a railing for persons walking or moving about the deck 13.
  • the upper ends of the support members 11 may be provided with sockets 40 which may simply receive the spigot ends of upstanding supports 41 for the top rails 39.
  • a pair of adjacent top rails 39 may be interconnected by a U-shaped member 42 in the manner shown in Figure 1.
  • a gantry module 100 including upstanding support members or legs 111 and roof assembly 112.
  • Each leg 111 includes an upper fixed portion 113 and a lower folding portion 114.
  • the lower folding portion 114 is hingedly attached to the portion 113 about a hinge 115.
  • Hinge 115 is preferably arranged so as to prevent folding portion 114 from folding outwardly from its position of alignment with fixed portion 113.
  • the folding portions 114 are illustrated in their operatively folded and unfolded attitudes.
  • the folding portions 114 may be suitably secured in their unfolded and folded attitudes.
  • a plurality of scaffolding modules 10 may be simply delivered to site with the required course adjustment of the foot assemblies 17 preferably made prior to delivery thereof.
  • the modules 10 are arranged in end to end relationship and interconnected by clamps of the type shown in Figure 7 or alternatively connected by bolting whilst fine adjustment of the foot assembly 17 may be carried out by adjustment of the nuts 15.
  • the support plates 29 are of course in conventional manner mounted on lengths of timber arranged along say a footpath and secured thereto by any suitable fasteners passed through apertures therein.
  • the side rails 32 may be then simply assembled and clamped to the support members 11 and the top rails 39 engaged in the manner described above.
  • gantry module described above may be of any physical dimensions and of alternative forms to that described. It will also be realised that many other forms of foot assembly may be employed to provide a pivotal mount to cater for footpath undulations.
