Definitions

  • THE PRESENT INVENTION relates to a support system and more particularly relates to a support system adapted to support falsework.
  • the support system is of the type known as a frame support system.
  • a frame for a falsework support system said frame com­prising two vertical legs interconnected by a plurality of horizontal transoms, each transom having, at each end thereof, a vertical connecting element, the vertical connecting element being releasably connected, at two points spaced apart in the vertical direction, to a res­pective leg of the frame.
  • each vertical connecting element is in the form of a plate, the plate being connected to the respective leg by means of bolts.
  • the plate may be a flat plate or a plate with a specially shaped cross-­section so that the plate can snugly abut the respective leg.
  • each leg is a hollow tubular form, each bolt having its head located within the hollow leg.
  • the interior of the leg defines at least one recess adjacent the exterior wall of the tube, the recess being dimensioned to receive the heads of said bolts, rotation of the bolts thus being prevented.
  • the configuration of the tube is such that the portion of the tube defining the recess is located beyond a circle having a predetermined radius and having a centre coincident with the axis of the tube, the circle representing a free unobstructed space within the tube.
  • the outer periphery of the tube is of substantially octagonal form, at least one face of the tube being associated with the inwardly directed projections which define said recess.
  • the tube is of substantially circular configuration having at least one radially outwardly extending projection defining said recesses.
  • one or more additional structural elements are each clamped to any one of the projections or between adjacent projections present on one or more legs of the frame.
  • the legs are formed of light weight alloy.
  • the horizontal transoms are formed of conventional scaffolding tube.
  • the frame may be provided with one or more screw jacks at the bottom and/or at the top of each leg.
  • each transom is provided with means adapted releasably to receive a brace or the like.
  • the brace receiving means com­prise a spigot securely attached to said connecting means, the spigot being provided with means to retain said bracing means thereon.
  • said retaining means comprise a pivoted locking lever contained within an axial recess in the spigot and movable to a position in which the lever projects outwardly from the spigot.
  • said retaining means comprise a nut or the like, the exterior of the spigot being threaded to receive said nut.
  • the frame may be provided with means to connect the frame to a similar frame mounted above the said frame.
  • the frame may be provided with a detachable cross brace and/or link bars and/or diagonals mounting element, detachably mounted in position on the frame, and provided with means to receive the cross brace.
  • the cross brace receiving means comprise a spigot and means to retain a cross brace in position on the spigot.
  • cross brace receiving means are bolted to the end of a transom.
  • a frame for use in a frame support system for faslework, said frame comprising two upright members interconnected by a plurality of horizontal transoms, each transom being connected to the adjacent frame member by means of a connecting element, each con­ necting element incorporating means adapted lockingly to receive the brace or the like.
  • the means adapted to receive a brace or the like comprise a spigot and means to retain a cross brace or the like on the spigot.
  • said retaining means comprise a pivoted locking lever mounted in an axial slot or recess formed in the spigot.
  • the retaining means comprise a nut, the exterior of the spigot being threaded to receive said nut.
  • the invention also relates to a falsework support assembly comprising a plurality of frames as described above.
  • a frame assembly 1 comprises two upright members or legs 2, 3. Interconnecting the legs are an upper horizontal transom 4 and a lower horizontal transom 5.
  • Each leg 2, 3 is formed of a strong alloy, and has a hollow cross-section as illustrated in Figure 2.
  • the leg 2 has an outer octagonal peripheral portion 6, four orthogonal faces of which are provided with inwardly directed protrusions 7, 8, the protrusions on each face defining between them a recess or channel 9.
  • the recess or channel 9 is dimensioned to receive snugly the head 10 of a bolt 11 which can pass through an aperture 12 formed at an appropriate location in the outer wall 6 of the leg 2.
  • the dimension of the channel 9 is such that the head 10 of the bolt cannot rotate when it is in position.
  • the bolt is adapted to receive a nut 14 utilised to secure a transom 5, in position, as will be described hereinafter.
  • the inwardly directed projections 7, 8 terminate with outwardly directed arcuate flanges 15, 16 which serve to define a central circular area 17 which is clear of all obstruction, the periphery 18 of the circular area being of such a size that a screwjack can readily be received within the central area 17 of the tube.
  • the inwardly directed projections 7, 8 and the lips 15, 16 can engage the engagement portion of a screwjack whilst permitting the elongate screw portion of the jack to move freely within the tube. If the tubular leg 2 is subjected to a knock and is thus dented, it is unlikely that the dent will extend into the central area 17 of the tube, and thus even if the leg is dented it will still be possible to utilise the leg in a satisfactory manner with the screwjack.
  • Each of the horizontal transoms 4, 5, terminates with a vertical end plate, the plate being designed to form a stiff node between the transom and the leg.
  • the end plate 19 provided at one end of the transom 5 is illustrated in Figure 3.
  • the end plate 19 is a vertical plate securely welded to the end of the horizontal transom 5, and maintained securely in position by means of triangular reinforcing webs 20, 21.
  • the vertical plate 19 (as can be seen from Figure 2) has a configuration such that the plate can be brought firmly into engagement with one of the said orthogonal faces of the leg 2, the plate having peripheral lips which abut the next two adjacent faces of the octagonal leg.
  • the plate 19 is secured firmly to the leg 2 by means of two bolts 11, as shown in Figure 2, and assoc­iated nuts 14.
  • the bolts are passed manually down in the interior of the leg 2 and are located in pre-formed apertures 12 in the walls of the leg 2.
  • the plate 19 is then mounted in position, with the bolts passing through appropriate apertures formed in the plate 19, and the nuts 14 are then located in position and tightened.
  • a projecting spigot 22 which has a locking lever 23 pivotally mounted in an axial slot formed in the spigot 22.
  • the locking lever 23 may move pivotally from a totally retracted position to a position in which it projects from the spigot as shown.
  • a bolt hole 24 is provided in the end of the horizontal transom 5, the hole 24 extending horizontally and being located in the region of the transom 5 that is reinforced by the reinforcing webs 20, 21.
  • a frame of the type described will be very rigid, by virtue of the fact that the vertical plates 19 provided at the ends of the transoms 4, 5 are each securely connected to the adjacent upright or leg 2, 3 at two spaced positions. Thus the frame will be relatively stiff and will resist any attempt to make the frame "lozenge”.
  • frames of the type described may have screwjacks mounted in the lower ends of the vertical legs 2 or in the upper ends of the vertical legs 2. Since the frames are fabricated from components which are bolted together if any one com­ponent becomes damaged, it is posisble to unbolt the component to facilitate the repair of the component, or to replace the damaged component with a new component. Whilst the legs 2 and 3 may be formed of an appropriate alloy, each transom may be formed of tubular steel, and may therefore be formed of conventional scaffolding tube. This enables conventional scaffolding couplers to be utilised to connect conventional scaffolding compon­ents to the transoms.
  • frames in accordance with the invention may easily be fabricated with transoms of any appropriate length. Thus it may be possible to have available relatively narrow frames, with short transoms, or relatively wide frames, with longer transoms.
  • Frames as described may be interconnected by link bars or the like.
  • Each link bar may be provided with means at the ends thereof adapted to be mounted on the spigots 22.
  • the locking lever 23 will be pivoted upwardly into the retracted position in which it is received in the axial slot to permit the link bar to be mounted on the spigot and the locking lever will subsequently return to a depending position in which a free end of the locking lever 23 projects downwardly out of the axial slot thus preventing the link bar from being inadvertently disen­gaged from the spigot 22.
  • Figure 4 illustrates a detachable brace connector 25 which has arcuate horizontal arm 26 having an aperture through which passes a bolt 27 which also passes through the bolt hole 24 provided at the end of the transom 5.
  • the bolt thus secures the horizontal arm 26 in position, the arm 26 being configured so that it lies immediately adjacent the outer periphery of the octagonal leg 2.
  • the arm 26 supports a vertical plate 28 having a configuration similar to the configuration of the plate 19.
  • the plate 28 has a main portion lying adjacent one face of the octagonal leg 2, and also has, at each side thereof, inclined flanges lying adjacent the next two adjacent faces of the octagonal leg.
  • a protruding spigot 29 having the same configuration of the spigot 22, the spigot 29 thus having a depending locking lever 30 corresponding to the locking lever 23.
  • a diagonal element 31, of tubular form, having a flattened end region 32 defining an aperture 33 can be mounted on the spigot 29, and can be retained in position by means of the locking lever 30.
  • the diagonal element 31 may be telescopic, and extends diagonally across the frame, as shown in phantom in Figure 1.
  • Additional bracing elements may also be mounted on the spigot, the additional bracing element extending in the directions indicated by the lines 33, 34 or 35, for example.
  • the design of the bracing arrangement utilised in any particular situation is within the ability of the man skilled in the art.
  • FIG. 5 illustrates a modified embodiment of the invention, illustrating a spigot 36 which may be in the position of the spigot 22 described above or which may be in the position of the spigot 29 described above.
  • the spigot 36 is mounted on a plate 37 (equivalent to the plate 19 or to the plate 25).
  • the spigot is pro­vided with a pivoted locking lever 38 (equivalent to the pivoted locking lever 23 or 30) and mounted on the spigot are a plurality of bracing elements 39.
  • the bracing elements have flattened ends so that they fit snugly adjacent one another.
  • the exterior of the spgiot 36 is threaded, as at 40, and a wing nut 41 may be mounted on the spigot. The wing nut may thus be tightened against the flattened ends of the bracing members 39, thus providing a secure connection.
  • the bracing elements may be mounted on the spigot 36 and may be retained by the locking lever 40.
  • a wing nut 41 can be threadedly engaged with the threaded exterior 40 of the spigot 36 and may be tightened against the flattened ends of the bracing members.
  • FIG. 6 illustrates a scaffolding arrangement incorporating frames in accordance with the invention.
  • a frame 1 as described above, is provided with screw­jacks 42, 43 which project downwardly from beneath the frame, the screwjacks 42, 43 being associated with base plates 44, 45 which rest on the ground.
  • screwjacks 46, 47 are provided which extend upwardly above the frame, these screwjacks being associated with head plates 48, 49 which support beams 50 upon which the falsework rests.
  • the screwjacks and the beams may be of a conventional design.
  • the frame 1 is illustrated as having a specific size, by selecting the length of the transoms 4 and 5 appropriately the frame 1 could be smaller, as indicated at 51, or larger, as indicated at 52. Appropriate diagonal reinforcing elements may be provided if desired.
  • Figure 6 illustrates that in a falsework support system incorporating frames in accordance with the invention it is possible to utilise a single prop 53 constituted by a tubular element 54 having same cross section as one of the legs of the frame.
  • the prop is provided with appropriate screwjacks 55, 56.
  • the frame 57 shown to the right hand of Figure 6 illustrates how frames in accordance with the invention may be interconnected by means of linking means comprising scaffolding tubes 58 connected to the transoms 4, 5 of the frame by means of conventional scaffolding fittings. It will thus be appreciated that the frames of the invention are very versatile and permit the assembly of many different arrangements of support frame work.
  • FIGS 7 and 8 illustrate one frame work support assembly made from frames in accordance with the invention. It can be ssen that in this assembly a plurality of frames 1 are mounted one above the other. The frames are interconnected by means of connectors 59 and connecting pins 60 which are conventional items known in the art.
  • FIG. 7 there are three sets of frames 1 which are spaced apart by appropriate distances.
  • the various sets of frames may be interconnected by means of horizontal linkbars 61, which may be connected to appropriate detachable brace connector 25, as illustrated in Figure 4.
  • Add­itionally diagonal braces 62 may be provided, if the load requires such diagonal braces to be provided.
  • Plan bracing may also be provided, if required.
  • the structure is illustrated supporting primary beams 63 and secondary beams 64, as is conventional.
  • a plurality of rows 65 of frames may be provided, and the frames of the rows may be interconnected by horizontal link bars 66 and/or cross braces and/or by diagonal lacing 67.
  • the structure illustrated in Figures 7 and 8 may be termed a "bird cage" frame support arrangement.
  • FIGs 9 and 10 illustrate an arrangement in which four rows 68 of frames are provided, the spacing between the rows being non-uniform.
  • each row 68 consists of two pairs of superim­posed frames 1.
  • the frames in the rows are inter­connected by a horizontal scaffolding tube 69 which are connected by means of appropriate connector 70, which may be a conventional scaffold coupler to the transoms of the frames 1.
  • diagonal bracing 71 can be provided if required.
  • This diagonal bracing may be formed from integral one-piece diagonal braces, or from telescopic braces, the braces being connected to a detachable brace connector.
  • the diagonal braces may comprise convention scaffold tubes connected to the horizontal transoms by conventional fittings.
  • Figure 11 illustrates a cross-section of an alternative member 72 which may be utilised to form a leg of a frame in accordance with the invention.
  • the member 72 is formed of an appropriate alloy, and has a cross-section which defines four rectangular protrusion 73.
  • Each protrusion 73 has an outer wall 74 which projects beyond the width of the protrusion 73 to form two projecting flanges 75.
  • Each protrusion 73 defines a channel 76 on the interior of the member dimensioned to receive the head of the bolt in a non-rotating manner.
  • a detachable brace coupler 77 is connected directly to a projection 73 by means of a clamp.
  • the clamp consists of a first element 78 comprising a plate having, at one side, a forwardly directed flange 79 terminating in an inwardly directed lip 80.
  • Bolt holes are provided in the flange 79.
  • the element is intended to cooperate with a second element consisting of an apertured plate which may have a shaped section 81 having an inwardly directed lip 82 at one end edge thereof, the set components being assembled so that the inwardly directed lips 80, 82 engage behind the flanges 75 provided on the front plate 74 of the projection 76, bolts 83 being passed through the apertures and being tightened to draw the components together.
  • a second element consisting of an apertured plate which may have a shaped section 81 having an inwardly directed lip 82 at one end edge thereof, the set components being assembled so that the inwardly directed lips 80, 82 engage behind the flanges 75 provided on the front plate 74 of the projection 76, bolts 83 being passed through the apertures and being tightened to draw the components together.
  • two bolts 83 are provided in a symmetrical arrangement, associated with nuts 84.
  • a spigot 85 corresponding to the spigots des­cribed above, is mounted on the first element 78. The spigot
  • the described detachable brace coupler may be located at any position on the leg, or any selected projection.
  • a similar clamping arrangement may be used to mount other coupling devices in position, including a conventional scaffold coupler.
  • a clamping device may be located between two adjacent projections on the leg and may be expanded to engage the projections, the clamping device thus being clamped in position.
