Definitions

  • the present invention relates to a scaffolding for supporting heavy loads, comprising a plurality of essentially 2-dimensional frame elements, each of which with the scaffold erected
  • Connection points is connected to at least one further frame element.
  • scaffolds are used to support formwork from below.
  • Such scaffolds generally have a relatively large height in relation to their plan dimensions, so that they have a tower-like shape when built up.
  • ceiling or joist formwork which is located at a relatively high height, can be supported from below and the corresponding ceilings or joists can be produced essentially only supported by the floor underneath.
  • a particularly suitable use is the manufacture of hall ceilings and bridges from reinforced concrete. It is particularly favorable that the height of the individual scaffolding towers is very variable, so that work can be carried out from uneven surfaces or there is great freedom with regard to the shape of the reinforced concrete parts to be created.
  • a height adjustment can be achieved, for example, by a different number of frame elements in the individual towers.
  • Systems on the market operate with a square outline of the scaffold and essentially two-dimensional frame elements with four connection points which lie on the corners of a rectangle, ie the frame elements are essentially rectangular.
  • two frame elements are always arranged parallel to each other on the sides of the square.
  • the two frame elements above are offset by 90 ° to the previous one. This alternating arrangement continues essentially over the entire height of the scaffolding tower.
  • a problem with such scaffolding towers is their stability.
  • the maximum permissible height depends on the load to be supported. If these load limits are exceeded, there is a risk of the scaffolding tower dodging sideways or buckling. It should be noted that the side wind load must also be taken into account for the load to be supported. In bridge building in particular, this is another very important limiting factor.
  • junctions of a frame element lie essentially on the corners of a triangle. This means that every single frame element is statically determined according to the laws of statics. By building the entire scaffold from individual statically determined frame elements this results in greater stability and greater load-bearing capacity of the overall scaffold than with a scaffold made of frame elements, the four connection points of which lie on the corners of a square and which are statically indefinite.
  • a base frame is preferably provided for installation on the floor, which in plan view has four connection points for connecting to the frame elements, which lie on the corners of a square, with two frame elements each connected to two connection points of the base frame when the scaffold is set up, that these frame elements are arranged parallel to each other, and the two frame elements next to it, offset by 90 ° to the previous frame elements, are each connected to a connection point of one frame element and a connection point of the second frame element.
  • the base frame can, for example, be supported on the floor at the four corners with a spindle foot, so that a level compensation can be accomplished.
  • an upper end frame can be provided at the upper end of the frame, in which spindle heads can also be provided for height compensation, for example with
  • Formwork beams work together.
  • the height of the scaffold can be adjusted as desired.
  • the connection points of a frame element preferably lie essentially on the corners of an isosceles triangle, the angle bisector between the two legs of equal length being essentially horizontal when the scaffold is set up.
  • Such a frame element has the advantage that it is
  • Angle bisectors can be mirror symmetrical and thus the structure of the scaffold can be simplified.
  • a base frame for setting up on the floor can preferably also be provided, which in plan view has three connection points for the
  • the bottom frame element is connected to two connection points of the base frame and the next frame element with one connection point each of the base frame and the previous one
  • Frame element is connected and the further frame elements are each connected to the two previous frame elements.
  • This construction has the advantage that the scaffold also has a statically determined construction, which further increases the stability of the scaffold. It can also be used with a much smaller one
  • connection points at the corner points of an isosceles triangle with a vertically arranged base is preferred, ie the - horizontally - height of the triangle intersects the base in the middle, with a triangular outline of the scaffold a frame element is preferred, in which the - horizontally running - height of the lying triangle intersects the - vertically running - base of the triangle in relation to one third to two thirds.
  • a frame element is preferably essentially T-shaped and the connection points of the frame element are provided at the three free ends of the T, the frame element being arranged in the form of a lying T when the scaffold is erected. This T-shaped
  • the construction of the frame element has the decisive advantage of using extremely few components. Only one vertical and one horizontal structural element is required. Correspondingly few connections have to be made between the individual structural elements during their manufacture. This allows both
  • Weight of the frame element and its manufacturing costs as well as storage and transportation costs can be reduced.
  • a frame element consists of only the following three
  • connection is formed in the directions perpendicular to the longitudinal axis of the pipe or sleeve. It should be noted in particular that the statically determined construction of the frame elements means that the connections are essentially only loaded in the direction of the longitudinal axis of the pipe or of the sleeve, as a result of which wear in the
  • frame elements which are essentially L-shaped can also be provided, particularly in the case of a square outline of the scaffold. Then the symmetry of the individual frame elements mentioned above is dispensed with, and the frame elements must each be arranged in a predetermined orientation when assembling the scaffold. Nevertheless, the savings in production, costs and storage or transport that are mentioned can be realized.
  • the invention further relates to a frame element for such scaffolding.
  • FIG. 1 shows a perspective view of a scaffold according to the invention
  • FIG. 2 is a perspective view of a base frame
  • FIG. 3 shows a perspective view of a frame element
  • Fig. 4 is a perspective view of a scaffold with a triangular base frame and corresponding arrangement of the

  • a base frame 4 can be seen, which is supported on height-adjustable spindle supports 6.
  • first frame elements 8 are arranged parallel to one another and essentially aligned with one side of the base frame 4.
  • second frame elements 10 are arranged parallel to one another, which are offset by 90 ° with respect to the first frame elements 8 and are each essentially aligned with one of the remaining sides of the base frame 4.
  • First frame elements 8 and second frame elements 10 are always arranged in pairs one above the other in order to form the height of the frame 2.
  • An upper end frame 12 is provided as the upper end of the frame 2, which is essentially the same Base frame 4 is, and ideally the same frame type can be used as base frame 4 or end frame 12.
  • spindle heads 14 are provided, on which, for example, formwork girders (not shown) can be supported. The spindle on the upper end frame 12 and on
  • Base frames 4 allow the scaffold 2 to be adjusted in height in such a way that overall heights can also be set which cover intermediate sizes between the multiples of frame elements 8, 10. In addition, they allow adaptation to uneven subsoil and non-level formwork types.

  • junctions 18 and 22 are essentially at the level of the base frame 4, while second junctions 16, 20 are at a higher level.
  • the individual frame elements 8 have a substantially T-shaped shape and have connection points 76, 78, 80 and 82 which are arranged essentially on the corners of a triangle.
  • the individual frame elements 8, 10 are each flat or 2-dimensional elements, i.e. with the scaffold erected, they essentially extend only along one side of the base frame 4 and vertically upward.
  • the first frame elements 8 and the second frame elements 10 are advantageously identical to one another, so that the base frame 4 is one has a square floor plan.
  • the side length of the base frame 4 is approximately 1 m.
  • the total height of the scaffold 2 can be 15 to 20 m and possibly even more.
  • the scaffold 2 can additionally be stiffened by cross struts 24, which can be inserted into corresponding openings 26 in the frame elements, the base frame and the end frame.

  • the tube 44 has a length of about 1 m. Measured in the direction of the traverse 46, the frame element 8, 10 also extends over approximately 1 m.
  • the first frame elements 8 are inserted with the tube 44 into the sleeves 18 and 22 and placed on the tube 35 and 36 with the lower opening of the double sleeve 48.
