Definitions

  • the invention relates to a flying scaffolding for buildings.
  • a flying scaffold is constituted by a nacelle which is raised or lowered as needed along an external wall by means of mittens and ropes usually fixed at hooking points arranged at the level of the roof.
  • the rail which must be carried by support members firmly anchored on the roof of the building.
  • the rail is formed of a plurality of elements assembled end to end, so that it can be adapted to the length of the facade.
  • the rail generally consists of a cylindrical tube on which the carriages can roll.
  • the wheels of the same pair arranged on the respective sides of a carriage, rotate in planes which converge downwards, while one of the carriages, said motor, further comprises a drive wheel with a rubber tire, frictionally bearing on the upper generator of the rail and integral in rotation with an external pulley maneuverable by a rope from the nacelle.
  • French patent n ° 1,297,234 provides for a winch with an endless cable and pulleys at the ends of the rail, the lateral displacement being obtained by maneuvering the winch.
  • These means are relatively complex and require the arrangement of return pulleys at the ends of the rail and of a cable running all along the rail.
  • An object of the invention is to provide a flying scaffold which is particularly well suited for working in horizontal strips along the facade of a building, comprising safety means to avoid accidents in the event of breakage of the support carriages, easily. movable and equipped easily adjustable support members to avoid any deflection of the longitudinal rail.
  • the subject of the invention is a flying scaffolding for a building, in which the nacelle is traditionally suspended from at least two carriages connected together by a removable spacer of length approximately equal to that of the nacelle used, and movable along a rail formed by a plurality of linear elements assembled, and arranged overhanging the top of the building by means of a series of support members placed on the roof, characterized in that in the vicinity of each of its ends, the spacer connecting the two carriages carries a T-shaped security bracket whose transverse bar is disposed inside the U-shaped rail, perpendicular to the longitudinal plane of symmetry of said rail and has a length greater than the spacing of the folded ends of the rail wings.
  • a rail 10 ( Figure 1), intended for the suspension and in lateral translation guidance, along the facade of a building, of a flying scaffolding nacelle (not shown), is formed by the end-to-end assembly of linear elements, namely a primer element 11, any number of intermediate elements 12 (only one in the example shown) and a terminal element 13.
  • Each element is provided with at least one suspension means (11a, 11b, 12a, 13a) arranged as will be said below -after and intended to be hung on the overhanging end of support members, shown in Figure 5, placed on the roof of said building.
  • All the elements are U-shaped profiles whose opening 14 faces downwards (FIG. 2) and which have a constant internal section from one end to the other of the rail 10.
  • the ends of the wings (10a, 10b) are folded inwards and preferably in an arc having a center angle 0 (greater than 90 °.
  • the inner face of these flaps forms the raceway of two carriages 15 and 16 each having at least two wheels such as 17 on each lateral side
  • the circular arc shape of the flaps envelops the lower part of the treads of said wheels which are thus guided without risk of lateral friction of the carriages against the internal face of the wings 10a and 10b of the rail.
  • the two carriages 15 and 16 are connected by a removable spacer 18 ( Figures 3 and 4), the length of which corresponds to that of the nacelle to be suspended and each of the carriages carries a suspension means 19 and 20 for mittens or other equivalent bodies , otherwise moored to the nacelle in a conventional manner.
  • the spacer 18 rigidly carries a bracket 21a in T whose transverse bar 21b is disposed inside the rail 10, perpendicular to the longitudinal plane of symmetry of said rail and has a length greater than the spacing of the lips of the opening 14.
  • This bracket ensures the safety of the suspension in the event of the axes of the wheels of a carriage breaking.
  • each rail element carries on its upper face two members 22, such as rings or the like for handling the element using a lifting device.
  • the rail elements are assembled end to end by embedding a female end on a male end in a movement from top to bottom.
  • the female end of the next element is lowered for assembly and locking.
  • the male end, such as 23 is free of any additional part, with the exception of an attached stop 28 carrying an ear provided with an oblong hole.
  • each element is welded on the upper face a support tab 25 whose projecting part is intended to rest on the upper face of the male end of the neighboring element.
  • a firmly welded stirrup 26 envelops the end part of the end 24 overlapping the middle part of the tab 25 and protrudes longitudinally so as to be able to overlap the end part of the end 23.
  • This stirrup 27 carries an ear 29 provided with an oblong hole, and a pin not shown, intended to secure the two elements of the rail.
  • each intermediate element 12 must have a male end 23 and a female end 24, while the initiating element 11 has a male end and is closed at the opposite end by a nozzle 31, and that the terminal element has a female end and an end closed by a nozzle 31.
  • FIG. 3 and 4 Such a system is shown in Figures 3 and 4. It includes a friction roller with a rubber bandage or the like applied against the underside of the rail 10 and fixed in rotation with a pulley 32 carried by the spacer 18 and having a trapezoidal groove - zoidal for endless rope 33, or notched for endless chain maneuverable from the nacelle.
  • the friction roller is constituted by two twin wheels 34a and 34b wedged on the same axis 35 as the pulley 32 and which apply respectively under the folded edge of each of the wings 10a and 10b of the rail. So that the pressure of the wheels 34a and 34b on the underside of the rail 10 is substantially constant despite the wear of the tires, the axis 35 pivots between the cheeks 36a and 36b of a yoke 36 articulated by the free end of said cheeks around an axis 37 passing through a socket 38 carried by the spacer 18, and subjected at its end opposite to the action of a spring 39 urging said end towards the underside of the rail 10.
  • the wheels 34a and 34b are located on the axis 35 between the cheeks 36a and 36b and the control pulley 32 is, on said axis, offset to the outside of the yoke 36.
  • a screw recall 40 makes it possible to act on the arm constituted by the yoke 36 to bring the wheels 34a, 34b out of contact with the rail 10 against the action of the spring 39, in order to allow the assembly of the assembly of suspension by engaging it at one end of the rail before fitting the end piece 31, or by engaging it from the start of assembly in the initiating element 11, before assembling the intermediate element 12 the nearest neighbor.
  • screw 40 instead of the screw 40, another equivalent means can be provided, for example a rod and cam assembly with two stable positions, or a locking device of the so-called grasshopper type, or a quick-release lever, so as to maintain it. in the compressed position of the spring 39 during the positioning of the carriages in the rail and its rapid release immediately after.
  • a rod and cam assembly with two stable positions, or a locking device of the so-called grasshopper type, or a quick-release lever, so as to maintain it. in the compressed position of the spring 39 during the positioning of the carriages in the rail and its rapid release immediately after.
  • the support member of the nacelle essentially comprises: a sole 101 with a front flap 102, intended to be placed on the top of the wall; two fixed arms 103 and 104 in a substantially vertical plane, integral with the sole 101 by means of sleeves 105, 106 and joining to carry an anchoring head 107; two movable arms 108, 109 capable of pivoting relative to the sole 101, for example by means of an axis 110 passing through the sleeves 105, 106, and approaching to carry the hooking member 111 supporting the nacelle ; and a rod 112 for adjusting the position of the mobile arms 108, 109 relative to the fixed arms 103, 104.
  • This rod 112 is provided with a drive crank 113, it is threaded and it rotates in a tube 114 for example.
  • This tube 114 is crossed by the threaded axis 115 of a shackle 116 which passes around a support axis 117 welded under the close ends of the arms 108 and 109. To the right of this axis 117, the arms 108 and 109 are slightly bent and they meet to form a sort of loop 118 beyond the latching member 111.
  • the anchoring head 107 essentially consists of a plate with raised edges and welded to the arms 103 and 104. It carries an anchoring ring 119 on which is fixed the end of a safety chain 120, the another end is fixed to the support pin 117. On the ring 119 is fixed a cable 121 intended to ensure the rear anchoring of the support member by any known means.
  • the anchoring head 107 has a simple notch 126 into which the end sleeve 127 of the threaded rod 112 is inserted.
  • This member 111 is for example a round iron rod, folded at its two ends 122, and having in its middle a curve 123 intended to receive the ring 124 for supporting a rail 125, running along a facade, and from which the basket is suspended.
  • the ring 124 When the ring 124 is housed in the curve 123, it urges it downwards, and at the same time it keeps the bent ends 122 of the hooking member 111 downwards. It therefore remains stable.
  • the support member according to the invention When the support member according to the invention is placed at the top of a wall, the sole 101 is on the wall and the flap 102 against the facade, the fixed arms 103, 104 are in a substantially vertical plane, and the rear anchoring is ensured by the cable 121 on the ring 119.
  • the threaded rod 112 is simply slid into a notch in the anchoring head 107.
  • the cranks 113 are operated to put the rail at the same height over its entire length. In the event that the mechanical connection between the threaded rod 112, the tube 114 and the shackle 116 becomes defective, the safety chain 120 could avoid an accident.
  • the threaded rod 112 can be removed from its notch; completely raise the movable arms 108, 109 against the arms fixed 103, 104 and fold the rod 112 along one of the arms 108 or 109 for example, to have a support member of reduced size, easily transportable, and which can be implemented very easily.
  • the spacer 18 is simplified and it carries in the vicinity of one of its ends a pin 52 on which pivots a bracket having a substantially horizontal arm 50 and a downwardly inclined arm 51, in the example shown.
  • a wheel 53 pivots on an axis 54.
  • a wheel 55 pivots on an axis 56. From this wheel 55, an endless rope 57 hangs freely until Platform.
  • the wheels 55 and 53 are connected to each other by means of a chain 59.
  • the wheel 53 carries an adherent external lining 60 constituted for example by a tire.
  • the length of the inclined arm and the masses of the wheel 55 and of the rope 57 are such that the wheel 53 is permanently applied against the underside of the rail.
