Definitions

  • the invention relates to an assembly scaffold for a formwork scaffold for circular structures made of concrete or the like. with a horizontally aligned, approximately ring-shaped, polygonal frame for a work platform with an upper flange and a lower flange, which are connected by means of truss struts, which are supported on columns, preferably three, so as to be height-adjustable, and each frame section of the polygonal frame is a separate part between two corner points , which is detachably connected to the adjacent frame sections, preferably screwed.
  • AT-A-340 672 describes such a device for erecting preferably large-scale structures, such as silos, swimming pools, digesters or the like. made of pourable materials, for example concrete, in which a height-adjustable work platform is provided.
  • This work platform is mounted on three extendable tubes, with an annular lattice girder being mounted, and on this annular lattice girder, radiation-like outwardly or inwardly projecting girders are mounted, on which the outer and inner formlining is suspended.
  • the work platform along with the formwork skins attached to it, is hoisted after the poured concrete has hardened.
  • a disadvantage of the known work platform can be seen in the fact that a separate work platform must be available for each working diameter and that the extendable tubes serving as supporting columns are arranged within the ring of the work platform and relocating the work platform or loosening and attaching it to the Guide tubes is a time-consuming and dangerous job because this can only be done below the work platform.
  • the object of the invention is to provide an assembly scaffold of the type mentioned, in which the work platform can be adapted to different building diameters and which furthermore does not have the disadvantages mentioned above.
  • the polygonal frame is angularly adjustable at the corner points and the frame sections on their outer sides comprise a flange of the columnar girders, while the side opposite this flange also bears against the formwork fixing rings.
  • the upper and lower flange sections of the frame sections are provided at the connection points in a fork-like manner with two connecting webs which, in the mounting position, alternately abut a, b, a, b.
  • the frame sections can be separated at each corner point and by inserting a further frame section or by inserting several frame sections, the diameter of the frame can be expanded as desired, as can be reduced by removing frame sections.
  • the polygonal frame can be adapted to the continuous circle.
  • two connecting webs lie at one end of the upper and lower chord sections at an angle to the longitudinal axis of the upper chord and lower chord sections. This makes it possible to work with portable tolerances in the manufacture of the frame sections.
  • An embodiment of the invention provides that the connecting webs are provided with holes for connecting screws, which are at least partially on an arc. Some of these holes are elongated holes. A hole is advantageously located next to the circular point of the circular arc.
  • Another embodiment provides that the connecting webs at the other end of the upper or.
  • Lower chord sections are divided into an inner and an outer web part, which are located on both sides of the upper and lower chord section.
  • FIG. 1 schematically shows a vertical section through an assembly scaffold according to the invention and the associated formwork
  • FIG. 2 shows a schematic top view
  • FIG. 3 shows a side view of a section of the working platform according to the invention
  • FIG. 4 shows a side view 5 shows a plan view of a frame section
  • FIG. 6 shows details A, B of FIG. 4, namely with the ends of the frame sections abutting
  • FIG. 7 shows a section along the line CC of FIG 6
  • FIG. 8 shows the connection of frame and carrier in horizontal section
  • FIG. 9 shows schematically the interlocking of the sections of the upper and lower flange
  • FIG. 10 shows a top view of a further exemplary embodiment of a frame section
  • FIG. 11 shows a side view of such a frame section.
  • the wall under construction is designated 1.
  • the formlining 2 lies inside and outside, which is formed, for example, from steel, light metal or also from wood or plastic.
  • the steel profile beams 3 of the formwork scaffold are held by outer polygonal rings 4 or are screwed to them.
  • each outer or inner ring 4 consists of ring sections 8 which are articulated to one another at the corners 9.
  • each ring section 8 is preferably formed by a double T-beam.
  • a square tube could also be used, but the double-T support offers advantages in terms of faster fixing after the ring 4 has been adapted to a new diameter.
  • the articulated connection can be made either by an axis or by bending the lower parallel web of the double-T beam.
  • the inner formwork is basically the same as the outer formwork.
  • the formwork skin 2 is followed by the standing steel profiles 3, which are held by polygonal rings 4.
  • the polygon rings 4 which are preferably height-adjustable as in the case of the outer formwork, also have to absorb the resulting ring pressure in the inner formwork, so that they have to be provided in an appropriate number and strength.
  • the three columnar supports 5 are provided for the work platform 6, which support the polygonal annular frame 16.
  • This is a framework consisting of an upper flange 17, a lower flange 18 and vertical and oblique struts 19, 20.
  • the frame 16 is formed by separate frame sections 16 '.
  • each frame section 16 ′ has an auxiliary strut 21.
  • the upper chord sections 17 'and the lower chord sections 18' are formed by square tubes, as are the vertical struts 19 and the oblique struts 20.
  • a different profile for example a double-T profile, which has the necessary buckling rigidity, could also be used will.
  • the frame 16 is formed by screwed together frame sections 16 '.
  • Each upper chord section 17 'and each lower chord section 18' is provided at its two ends with connecting webs 22, 23 which, as can be seen in FIG. 9, interlock with one another in alternation (a, b, a, b), so that in each case one connecting web 22 on one Connecting web 23 is present in the same sequence.
  • the connecting webs 22 are arranged at an angle to the longitudinal axis of the upper or lower chord section 17 ', 18' and the connecting webs 23 are divided and there is a part on each side of the upper and lower chord section 17 , 18th
  • Each connecting web 22, 23 is provided with holes 24, 25 through which the connecting screws protrude. Furthermore, the connecting web 23 is provided with elongated holes 25 which are located on a circular arc, in the circle point of which there is also a fastening hole 24.
  • one or more frame segments 16 ' can be removed from the frame 16 by loosening the connecting screws between three frame segments 16', whereupon the frame 16 can be adjusted to a smaller diameter by subsequent angular adjustment at the corner points 9 'of the polygonal ring can.
  • This frame section 16 ' has on its upper chord section 17' holding means 26 which comprise a flange 5 'of the double-T beam 5 and via which the upper chord section 17' is connected to the flange 5 ', for example screwed to it.
  • the second flange 5 "of the double-T profile of the beam 5 is connected in a similar or identical manner to the rings 4 of the formwork framework.
  • the connection can be made, for example, by screwing.
  • the formwork scaffold and the work scaffold form a unit.
  • the work scaffold is guided vertically in the formwork scaffold.
  • the attachment of the work platform does not have to be carried out below the work platform.
  • the beams 5 can be secured against buckling directly on the concrete wall, which makes the otherwise necessary dangerous work below the work platform unnecessary.
  • each frame section 16 ' can be designed as a three-dimensional framework.
  • the frame sections 16 ' are advantageously trapezoidal in plan view.
