Definitions

  • the invention relates to a method of replacing frames in facade openings above ground floor level, such as frames around windows, wherein a suspended scaffold is initially erected through the window, permitting one or more persons to work at the external side of the window, and then the old frame is removed, optionally piecewise.
  • the method according to the invention stipulates that the new frame is arranged on the scaffold during the erection of it, so that the parts of the scaffold passing through the window opening also pass through the new frame, and that, after the removal of the old frame, the new frame is inserted, following which the necessary external finishing treatment is carried out from the scaffold.
  • a complete new frame is inserted in one integral piece in replacement of the old removed frame, and since the new frame, already before or during the erection of the suspended scaffold, is placed around the girders which connect the external side with the internal side of the scaffold, the new window frame may be inserted in one piece without dismantling the scaffold.
  • the new frame may be arranged either at the external side or at the internal side, and it will depend on the type of the window and other circumstances which of the two options is the most expedient one.
  • the invention relates to a suspended scaffold for suspension from within a facade opening, such as a window in a building, with an internal engagement part adapted to engage the internal wall face around the window and external engagement parts adapted to engage the external wall face around the window and to carry a working platform for one or more persons, said engagement parts being kept together by girders, which pass through the window, and internal and external load-bearing beams extending in parallel with the wall faces, characterized in that the girders pass through the window opening at a distance from all frame parts, and that the load-bearing beams, which extend in parallel with the external wall face, for connecting the external engagement parts with the girders extend at such a distance from the external wall face that there is room between the load-bearing beams and the wall face for the passage of a frame part which is intended for insertion into the window opening.
  • the window frame may be suspended in a simple manner from the girders when these are mounted, and there will be enough room between the girders and the frame for the insertion so that an artisan can insert the frame into the facade opening without difficulty when the old frame has been removed.
  • the scaffold shown in fig. 1 has internal engagement parts at each side of the window,
  • the engagement parts are formed as vertical rods 1 which engage the wall along their respective sides of the window,
  • a part 3 is provided in extension of the vertical part 1 of each rod and extends obliquely outwards from the wall and down toward the internal floor, said inclined part 3 having a foot by means of which the inclined part rests on the floor.
  • a plurality of horizontal carriers 2 is provided at the vertical part 1 of each rod.
  • a beam 4 lies on a respective horizontal carrier 2 at a suitable height so that it passes across the lower part of the window opening.
  • Two connecting elements 6 connect the beam 4 with its respective horizontal girder 7, which extends through the window opening at a suitable distance from side parts as well as bottom parts of the frame 5 which is to be replaced.
  • each girder is connected with a respective load-bearing beam 8 which extends in parallel with the outer wall and down to engagement parts 9, which constitute the engagement with the outer wall.
  • the external parts of the suspended scaffold are shown in dashed line in fig. 1.
  • the load-bearing beams extend in an inclined direction along the external wall away from the window, so that the engagement parts 9 will engage their respective sides of the window.
  • girders 10 which extend horizontally away from the outer wall, and between which a working surface 11 is mounted.
  • a railing 12 surrounds the working surface 11 in the usual manner.
  • Figs. 4, 5 and 6 show how a new window frame 12 may be suspended from the girders 7 during the insertion, so that the girders 6 are moved through the frame 13. It appears from fig. 5 that the new frame can hang freely down, because no engagement parts are arranged in the area just below the suspended scaffold, and because the load-bearing beams 8 extend at such a distance from the external wall face that there is room for the frame 13 in this area.
  • the new frame 13 may therefore be suspended outside the window opening in many other ways, but it is necessary that the girders 7, which interconnect internal and external parts of the suspended scaffold, pass through the frame 13. It is also necessary that the girders pass through the window opening at such a distance from frame parts that there is room for the mounting of the new frame 13 between the girders 7 and the opening in the facade.
  • the old window frame 5 is sawn through at one or several places, and is removed piecewise. Then the new frame 13 may be passed up into the opening and be secured to the masonry in the usual manner, and the external finishing treatment can now take place using the suspended scaffold before this is dismantled and is ready for use for the replacement of the next window.
