Definitions

  • the present invention relates to loading platforms and rubbish chutes employed in the construction of buildings, particularly high rise buildings.
  • loading platforms are employed to deliver and remove material from the various floors under construction.
  • landing platforms are used in conjunction with the crane, which has a lift cable which delivers to or removes the material from the landing platform.
  • Known landing platform have consisted of two major beams which are generally horizontal, parallel and co-extensive.
  • the beams extend outwardly from a floor of the building under construction.
  • the inner ends of the beams are engaged by props to secure the beams in position.
  • Extending between the beams is a floor, while around the forward end of the platform there is a rail for safety purposes.
  • the landing platforms have been used in conjunction with cranes placed at a remote location relative to the landing platforms. This is particularly necessary where the landing platforms are vertically aligned and the crane must have access to the forward edge of each of the platforms.
  • landing platforms have suffered from the disadvantage that they are difficult to install due to their size and weight. They are also expensive to transport since they occupy considerable volume. A still further disadvantage is the requirement for several sizes of landing platforms. Accordingly, several sizes need to be manufactured and stocked.
  • a still further disadvantage of known landing platforms is the limitation in respect of the loads which may be applied thereto.
  • a foldable landing platform comprising: a pair of generally parallel co-extensive transversely spaced horizontal beams; a plurality of brace members extending between the beams and secured thereto; a floor panel supported on said brace members; and two side panels pivotally secured to the beams and movable from a generally upright position extending generally normal to said floor panel, and a folder transport position located adjacent said floor panel.
  • a landing platform comprising: a pair of generally parallel, horizontal, co-extensive, and transversely spaced beams; a platform portion supported on said beams adjacent an end thereof; a pair of elongated prop members to extend from said beams to an overhead structure to secure the beams in position; and pivot means pivotally supporting each prop member on an associated one of the beams, each pivot means including a lateral movement support enabling movement of the prop member from a position spaced laterally of the beam, to a position spaced above the beam, and pivot means enabling pivotting of the prop member about a generally horizontal axis extending transverse of the associated beam so that the prop member can pivot from a position generally parallel to the beam, to a position extending upwardly therefrom.
  • an overhead protector to be used with a crane, said protector comprising: a support frame; a generally horizontal sheet member supported on said frame and below which a vehicle or workers may be located so as to be protected thereby, an aperture in said member through which a cable may pass; and a cover extending over said aperture, said cover having a slot extending inwardly from an edge of said cover and through which a crane cable may pass, and wherein said cover is movably supported so as to follow movement of the cable.
  • a landing platform comprising: a pair of generally parallel co-extensive transversely spaced horizontal beans; track means supported on and extending longitudinally of each beam; a floor panel extending between the beams and movably supported on the track means for longitudinal horizontal movement parallel to the beams from an outer position to an inner position with respect to a building which is to support the landing platform.
  • the landing platform 10 consists of a pair of generally parallel co-extensive transversely spaced "I" beams 12 which are of a fabricated construction.
  • Each beam 12 consists of upper and lower tubular members 13 joined by a web 14. Extending between the beams 12 are braces 15 which rest upon and are secured to the members 13 by bolts 16. Resting on the braces 15 is a floor panel 17.
  • side panels 18 Secured to the beams 12 are side panels 18 which are pivotally movable from an erect operative position extending generally normal to the floor panel 17, to a folded transport position located adjacent the floor panel 17.
  • the side panels 18 are directly attached to the beam 12, and more particularly the web 14.
  • the side panels 18 could also be secured to the beams 12 by being pivotally mounted on the floor panel 17.
  • the side panels 18 consist of panel members 19 secured to a frame 20.
  • the frame 20 includes eyelets 21 which engage eyelets 22 fixed to the beam 12. Extending between the eyelets 21 and 22 are pivot pins 23. To retain the panels 18 in the upright position, bolts 24 pass through the side panels 18 and engage the member 13. It should be noted that the pivot pins 23 are spaced from the general plane of the panel 19.
  • each side panel 18 is provided with a hinge assembly 25 to receive pivot pins 26 which pivotally attach doors 27 to the side panels 18.
  • the side panels 18 are provided with eyelets 29 which engage pins 30 of the roof assembly 11 to secure the roof assembly 11 in position.
  • the roof assembly 11 includes side panels 31, and a roof panel 32.
  • the side panels 31 are pivotally attached to the roof panel 32 so as to be foldable to the transport position as best seen in Figure 8.
  • the roof panel 32 is provided with a slot 33 which is reinforced, and which enables a crane cable to pass through the roof panel 32.
  • the beams 12 are also provided with hooks or eyelets 34 which can be used to lift the landing platform into position.
  • braces 15 and floor panels 17 may be used to vary the width of the landing platform 10. In such instances different length doors 27 would also be required as would a different length kick panel 28. Still further, the beam 12 may vary in length and dimensions to accommodate differences in working requirements such as expected weights to be received on the landing platform 10.
  • the landing platform 30 consists of a pair of generally parallel co-extensive transversely spaced "I" beams 32.
  • Each beam 32 consists of upper and lower flange 33 joined by a web 34.
  • Extending between the beams 32 are braces 35 which rest upon and are secured to the flange 13 by bolts. Resting on the braces 35 is a floor panel 37, preferably formed of sheet metal.
  • side panels 38 Secured to the beams 32 are side panels 38 which are pivotally movable from an erect operative position extending generally normal to the floor panel 37, to a folded transport position located adjacent the floor panel 37.
  • the side panels 38 are directly attached to the beam 32, and more particularly the web 34 by pivots 16.
  • the side panels 38 could also be secured to the beams 32 by being pivotally mounted on the floor panel 37.
  • the side panels 38 consist of panel members 39 secured to a frame 40. Secured to the rear of the panels 39 are braces 41 which are bolted to the beams 32 via bottom flanges 42 secured to the bases 41.
  • each side panel 38 is provided with a hinge assembly to receive pivot pins which pivotally attach doors 47 to the side panels 38.
  • each beam 32 Secured to each beam 32 is a pair of prop members 43 and 44, which are pivotally movable from an erect position extending generally upwardly and normal to the beam 32, to a folded configuration located between the webs 33.
  • the prop members 43 and 44 engage adjustable jacks 45 which in turn engage a floor or structure above the landing platform 30.
  • the adjustable jacks apply a compressive force to the prop members 43 and 44 to secure the beams 32 in position.
  • the prop members 43 and 44 are pivotally attached to their associated beams 32 by means of pivot assemblies 46 and 48.
  • Each pivot assembly 46 and 48 includes a sleeve 49 through which a pivot pin 50 passes.
  • the pin 50 as a stop 51 at one extremity, with the other extremity being attached to the associated prop member 43 or 44 by a radially extending flange 52.
  • Each prop member 43 and 44 includes a bottom flange 53 through which bolts 54 pass to secure the prop member 43 and 44 to the flange 33.
  • the pins 50 associated with the prop member 43 is located at a lower position relative to the pin 50 associated with the prop member 44. This enables the prop member 43 and 44 to be folded to positions such that the prop member 43 is located above the prop member 44 in their retracted positions. To move the prop member 43 and 44 between their folded and erected configurations, the prop members 43 and 44 need to move in a direction parallel to the pins 50.
  • the prop members 43 and 44 may then pivot between a generally horizontal orientation and a
  • the above described preferred embodiment of the present invention has the advantage of the platform 30 being foldable to a generally flat configuration. This facilitates stacking and transportation of the platform 30. Also by having the side panels 38 and the prop members 43 and 44 pivotally attached to the beams 32, erection of the platform 30 is relatively quick and easy.
  • flanges 33 may also be advantageous to provide with "male” and “female” couplings also to facilitate stacking.
  • FIGs 27 to 31 there is schematically depicted a landing platform 60 which is a modification of the platform 30 of Figures 16 to 26.
  • the side panels 38 are pivotally secured to the floor panel 37 ( Figures 27 to 31).
  • the floor panel 37 is attached to a pair of supports 61 which in turn are pivotally attached to the beams 32. Accordingly, the assembly of the supports 61, floor panel 37, side panels 38 and doors 47 are pivotable to a position extending generally normal to the beams 32. This particular position is illustrated in Figures 29 and 31. In this particular position, the platform 60 would then clear the way for a crane to deliver objects pass the platform 30.
  • Figures 27 to 33 have the advantage of enabling a series of landing platforms to be located in vertical alignment.
  • FIG. 34 to 38 there is schematically depicted an overhead protector 70.
  • the overhead protector includes a series of generally parallel, horizontal and co-extensive transversely spaced beams 71.
  • Prop members 72 extend upwardly from the beams 71 to secure the beams in position.
  • Extending between the beams 71 are floor panels 73, while the forward edge of the overhead protector 70 is provided with an inclined edge panel 74.
  • the edge panel 74 being supported by angled brackets 75 secured to the webs 76 of the beams 71.
  • This particular overhead protector 70 is sufficiently strong to support scaffolding 77 directly supported thereon.
  • FIG 39 there is schematically depicted a landing platform 80.
  • the landing platform 80 includes a narrow portion 81 and an enlarged portion 82.
  • the narrow portion 81 being dimensioned to pass between vertical uprights 83 of a scaffold assembly 84.
  • the landing platform 80 would be provided with side panels 85.
  • the embodiment of Figure 39 has the advantage of providing a larger landing platform that what has been traditionally available.
  • FIG. 40 to 43 of the accompanying drawings there is schematically depicted a landing platform assembly 90.
  • the assembly 90 is adapted to be used in construction or renovating a building 91 having floors 92.
  • the floors have outer edges 93.
  • the landing platform assembly 90 includes a plurality of landing platforms 93 which are vertically aligned and each consisting of a pair of generally parallel co-extensive transversely spaced "I" beams 94.
  • the beams 94 have their inner ends supported on the floors 92 and if so required, may be held in position by "props".
  • each pair of beams 94 Movably supported by each pair of beams 94 is a movable floor 95, which is movable between a retracted position spaced inwardly with respect to the building 91, and an outer position spaced outwardly of the floors 92.
  • the horizontal beams 94 are supported by the vertical beams 96 so that the landing platform is free-standing.
  • the floors thereabove are retracted so that the crane may move inwardly with respect to the building so that the material may be located above the floor which is located at its outward position.
  • the above described preferred embodiment provides the advantage that a mobile crane is not required.
  • the use of the crane 98 in conjunction with the movable floors 95 overcomes the need for a mobile crane.
  • the overhead protector 110 includes a sheet member 111 preferably formed of steel.
  • the sheet member 111 provides protection for workers and any vehicles located beneath the protector 110.
  • the protector 110 includes a generally rectangular side frame 112.
  • the sheet member 111 is formed with an aperture 113 through which a crane cable 114 may pass to engage or disengage an object 115 to be lifted by the crane.
  • the aperture 113 extends inwardly from an edge of the sheet member 111.
  • Covering the aperture 113 is a cover 116 which is movably mounted on the sheet member 111. If so required, guides or tracks may restrict movement of the cover 116 to ensure that it extends over the aperture 113.
  • the cover 116 is provided with a slot 117 through which the cable 114 passes.
  • the slot 117 extends inwardly from an edge of the cover 116.
  • the slot 117 has an enlarged entry portion 118 to facilitate location of the cable 114 within the slot 117.
  • the operator moves the cable from a remote position into the slot 117. Thereafter the object 115 is engaged or disengaged, and the cable 114 again moves from within the slot 117 to a remote position where at the cable 114 may be raised without fouling the overhead protector 110.
  • the overhead protector 110 is supported on a plurality of horizontal beams 119 secured in position by means of props 120. As can be seen, the protector 110 is located at sufficient height to clear the vehicle 121.
  • an opening 136 Formed in the floor panel 134 is an opening 136 covered by a removable or pivotally mounted cover plate 137. Also extending across the opening 136 is a grid 138 which may also be removable and/or pivotally mounted.
  • Supported on the beams 132 are side panels 139 as well as forward gates 140.
  • the chute 131 Supported on the beams 132 is the chute 131, which includes a vertically extending rubbish duct 141 which has a first pair of upper hooks 142 which engage over the side panels 139.
  • the duct 141 has a second pair of hooks 143 which may be provided with projections engaged within recesses formed in the beams 142.
  • Extending outwardly in a transverse direction from the duct 141 is a delivery chute 144 which extends to the opening 16 so that rubbish delivered through the opening 136 is delivered to the interior of the duct 141 via the delivery chute 144.
  • the above described preferred embodiment has the advantage that the rubbish chute 131 does not require its own supporting structure but merely attaches to the landing platform 130. Still further, the rubbish chute 131 is located externally of the building thereby not hindering normal building operations and allowing final finishing of the building.
  • the ends of the beams scrape along the concrete floor which is to support the platforms. This has the effect of subjecting the crane to shock loading and damaging the concrete floor.
  • the extremities of the beams are provided with rollers or curved plates.
  • the end portions of the beams 12, remote from the doors 27, are provided with flanges 150 which notatably support rollers 151.
  • the rollers 151 are positioned so as to only engage the concrete floor when the beams 12 are inclined. During installation the beams 12 are inclined to maintain contact between the rollers 151 and the concrete floor.
