Definitions

  • the invention relates to construction platforms, that is to say temporary landings which in use extend away from an exterior face of a multi-storey building under construction.
  • One previously proposed platform comprises a pair of generally parallel, co-extensive, transversely spaced apart, horizontal beams which extend outwardly from a floor of a building under construction, a landing floor extending between the beams, and a safety rail extending about the outer free edges of the platform.
  • the beams comprise supported portions that are fixedly secured on a floor of the building and cantilever portions that project from the building and carry the landing floor.
  • Each beam may be so secured in position by at least two length adjustable struts which extend between a portion of the beam contacting one floor and an adjacent (usually the next above) floor of the building.
  • inboard and outboard are used hereinafter with reference to a building, in the sense that items designated as inboard are disposed, when in use, within the perimeter of a relevant floor of the building, whereas items designated as outboard project from the building when in use and are disposed outside of that perimeter.
  • the terms are similarly used to designate the positions for the time being of movable items that may be inboard at one time and outboard at another.
  • the invention is defined in the claims hereinafter and characterised over AU-A-63026/90.
  • the invention provides construction platforms of the kind having a retractable deck including locking devices for retaining the movable deck in selected operating positions and wherein the deck is bounded along its outboard edges by safety barriers irrespective of its position.
  • the invention provides retractable deck type construction platforms as aforesaid wherein the entirety of the outboard portion of the platform is retractable to an inboard position.
  • the invention consists in a construction platform comprising a stationary support structure adapted to be fixedly secured to a floor of a building under construction, a landing deck having an outermost edge carried by said support structure and able to move to and fro between at least one inboard and at least one outboard position relative to the building, immobilising means to releasably lock the deck in said at least one outboard position, and safety barrier means movable with the deck and extending along its said outermost edge.
  • the support structure comprises stationary cantilever beams on which the movable deck may ride and which support the deck in the outboard position.
  • the safety barrier means may comprise fixed safety railings or walls extending along those beams and swing mounted, lockable gates extending (when closed) along the outermost edge of the deck and moving therewith.
  • a self supporting deck may extend as a cantilever from the support structure when in its outboard position.
  • the safety barrier means may comprise safety barriers extending along the side edges and the outermost edge of the deck and moving therewith.
  • each platform 100 comprises a semi-permanently erected stationary support structure comprising side rails or beams 102 and a movable landing deck 103 which is supported by and travels upon the beams 102 on rollers or bearings as described in more detail hereinafter.
  • the deck 103 may be shifted between an inboard position (as shown in the two uppermost platforms of the figure) and an outboard position (as shown in the bottom platform of the figure), so that a load can be lifted straight through to the overhead rail 101.
  • Each platform 100 further comprises safety barrier means comprising side walls 104 extending along at least the outboard portions of the beams 102 and folding or swinging doors 105 mounted on the deck 103.
  • An end gantry 105 may be required to support the far end of the rail 101.
  • FIG. 2 shows this type of construction platform permitting a load to be picked up from, or delivered to, a truck 106.
  • each platform is secured in place by telescopic struts 107 which may be located in pairs on either side of the platform and which may be manually or otherwise extended to secure the inboard portions of the beams 102 between floors of the building.
  • FIGS 3 to 17 inclusive illustrate in greater detail the embodiment of the invention appearing in figure 1.
  • the rear portion 7 of one of the support structure beams 102 may partially house electrical components depicted in Figures 7 and 8, being a drive motor 108, operating switches 109 and a rear limit switch 110 for shutting off the motor 108 of the drive means which advances and retracts the movable deck 103.
  • the platform may also include a front limit switch 111 and various locking pins 112 for immobilising the deck in predetermined positions of use.
  • a rear security gate or chain 113 may also be provided.
  • the deck 103 may comprise substantial Rectangular Hollow Section side members 114 with longitudinally extending flange plates 115 affixed to a rigidified floor panel 116 and running as movable rails upon supporting guide rollers 117 mounted on the respective I-beams 102.
  • FIG. 10 illustrates the drive means of the embodiment now being described.
  • Those means comprise the electric 108 or other motor driving a driving wheel 118 through a right angled gearbox 119 mounted on a beam 102.
  • the wheel 118 has a high friction surface to minimise slip between it and the floor panel 116.
  • This friction drive mechanism further includes an adjusting or tensioning screw 120 which is used to increase or decrease the amount of pressure exerted by the wheel 118 on the deck floor 116.
  • the friction roller 118 is held on a pivoting bracket 121 which is raised or lowered by adjustment of the tension screw 120.
  • Figure 11 illustrates an alternative drive means for shifting the deck 103.
  • the drive motor and gear box mounted on the beam 102 turns a pinion of a rack and pinion pair 122.
  • the pinion is mounted for rotation about a fixed vertical axis and engages a longitudinally extending rack on the rail 114 through a slot in the web of the beam 102.
  • Rotation of the pinion gear causes the deck 103 to advance and retract.
  • Guide rollers 123 and 124 prevent the rack and pinion from becoming disengaged, and wheel 125 supports the weight of the deck and provides for its free movement.
  • FIGS 3, 4 and 5 illustrate in greater detail a preferred embodiment of a locking mechanism, being an immobilising means of the embodiment of the invention now being described.
  • the illustrated mechanism comprises a latch bolt 126, a bolt guide 127 and a clip 128 to hold the bolt 126 in a retracted inoperative position.
  • Figure 4 illustrates the locking mechanism in an operative position with bolt 126 extending through openings in the top and bottom flanges of support beam 102, and through a hole in the edge margin of the movable deck 103 when the hole and openings are brought into register thereby preventing relative sliding movement between the deck 103 and the beam 102.
  • Figure 5 illustrates the locking mechanism in an inoperative position with bolt 126 (in ghost outline) in a retracted position in engagement with the clip 157, thereby permitting relative sliding movement between the deck 128 and the beam 102.
  • a similar locking mechanism may be used as immobilising means in fully retractable platform embodiments in which the retractable beams of a sliding deck are slidably supported within respective stationary guides of an inboard support structure, to prevent relative movement therebetween.
  • FIGS 12, 13 and 14 illustrate details of the outer edge of the embodiment now being described, with the deck 103 in its outboard position of use.
  • bracing means for the platform comprising a pair of elongate stay elements 129, each having an end hinged by means of hinge joint 130 or otherwise pivotally mounted to a top edge of the exposed end of the retractable deck 103.
  • the other end of each of the stay elements 129 is releasably fastened or secured to a respective safety wall 104.
  • the latter securement may be effected by the releasable fastening means shown in more detail by Figures 13 and 14 comprising a tongue 131 having one end welded or otherwise attached to the stay element 129 thereby to extend substantially perpendicular to the longitudinal axis of the stay element 129.
  • the tongue 131 has an opening 132 piercing it near its other end.
  • To fasten the stay element 129 to the safety wall 104 the tongue 131 is positioned to extend through an aperture 133 in an upright member 134 to enable a latch pin 135 having a hooked end 136 is then driven into said opening 132 thereby releasably securing the stay element 129 to the safety barrier wall 104.
  • the latch pin 135 also extends through a clearance hole in a substantially horizontal member 137 of the wall 104 with the hooked end 136 hooked thereover.
  • the bracing means further comprise locating holes 138 in end plates 139 applied to the beams 102 adapted to receive pins 140 protruding from the front edge of the deck 103. Those pins 140 thus constitute the third points of triangular constructions positively bracing the deck 103 and the beams 102 into a rigid entity.
  • Figure 15 shows an alternative bracing structure wherein the simple pins 40 are replaced by tongues 141 adapted to pierce slots in the end plates and thereafter accept cotter pins 142 to lock the deck in place and provide further immobilising means.
  • the end edge of the deck 103 is able to be closed by means of doors 157, detachably hinged to the walls 104.
  • doors 157 detachably hinged to the walls 104.
  • the gates and/or chain 113 at the inboard end of the deck is/are primarily relied upon as a safety measure.
  • FIGS 16 and 17 illustrate a pair of struts 143, such as struts 107, together with a releasably secured strut brace 144 to impart rigidity and stability to the strut structure.
  • Each strut 143 comprises a Rectangular Hollow Section (RHS) member 145, a manually adjustable jack screw 146 with one end extending into the hollow core of tubular member 145, wing nut 147, floor or beam abutment means 148 at the other end of screw 146 and a bracket member 149.
  • RHS Rectangular Hollow Section
  • Said bracket member 149 comprises a tubular abutment member 150 of substantially the same cross section and dimensions as member 145, disposed within a sleeve 151 of substantially the same cross sectional shape but of larger dimensions, formed so that the bracket member 149 fits neatly over and sits on the end of the tubular member 145.
  • a flange 152 projects from the sleeve 151.
  • the flange 152 provides a mounting for the ends of brace element 144.
  • the brace element 144 is in the form of an elongate C-section structural member.
  • the brace element 144 is mounted to the bracket member 149 by fastening means, for example the nut and bolt illustrated in Figure 17.
  • a construction platform having a self supporting cantilever landing deck 200 may be provided.
  • the deck 200 may be fully extended to an outboard position or retracted to an inboard position using human, electrical, hydraulic or other forms of power, whereupon no portion of the platform is outboard of the building, as the landing deck 200 is carried by an entirely inboard stationary support structure 201.
  • the support structure 201 comprises extendable struts 202 and supports the retractable deck 200 on rollers or the like. It also comprises drive means for shifting the deck 200.
