Definitions

  • the invention relates to a method for the erection of a dome, cone or pyramid-shaped cover made of concrete for buildings and civil engineering, in particular for container-like structures, annular sections being produced successively starting from the upper edge of the surrounding wall of the building.
  • Dome roofs in particular are used because of their favorable static properties as support-free covers, particularly for round containers.
  • Dome roofs can also be made from individual ring sections, these ring sections being made from different materials. In any case, with these dome roofs made in antiquity, the entire dome had to be fully encased.
  • the object of the invention is therefore to create a method according to which such covers can be produced in an economical manner and with the least possible formwork and scaffolding material.
  • successive annular sections are produced with an annular covering and / or beam support formed in each case on the inner edge, radial supports of a formwork construction in the invention of the first annular section adjoining the peripheral wall on the one hand on the peripheral wall and on the other a support frame running parallel to the surrounding wall at a distance, and that when the further annular sections are erected, the radial supports are supported on the one hand with their inner ends against the support frame which is shifted towards the center of the structure according to the width of the section and on the other hand with their outer ends in Area of the edge-side cover and / or beam support of the hardened, annular portion of the cover can be hung.
  • the required scaffolding material can be reduced to the area of an annular section of the cover. It is then possible, for example, to form and produce annular sections with a width of approximately 5 to 6 m, whereupon this formwork and scaffolding material can in turn be used for the next annular section.
  • the required strength is achieved by the covering carrier produced in the ring-shaped sections on the inner edge of the ring-shaped sections, since this covering carrier takes over the static function of the not yet closed dome roof. After hardening and reaching the required strength, the corresponding ring section is switched off. The corresponding ends of the radial supports can therefore be attached to the relevant edge of the hardened annular section, so that the annular section which has already been created can practically be incorporated into the formwork support structure.
  • FIG. 1 consists of a surrounding wall 1 and a dome-shaped cover 2.
  • this cover 2 is now formed from individual annular sections A, B and C, which are successively switched on and cast.
  • the corresponding sections in the exemplary embodiment shown are in each case on the inner upper edge of the ring-shaped sections A, B and C. annular coating carrier 3 cast. This takes over the static function of the not yet closed dome roof.
  • annular coating carrier 3 cast. This takes over the static function of the not yet closed dome roof.
  • the center area is closed in the last section of the process, so that no coating carriers 3 are then required in this center area.
  • the required static conditions are also met for this covering carrier.
  • prefabricated concrete panels 5 (corresponding to FIGS. 8 and 9) serving as lost formwork can be used.
  • These precast concrete slabs 5 are correspondingly conical, so that they can each bridge the space between the radial supports 6. This results in a further saving in formwork material.
  • these precast concrete slabs 5 can generally have a length of 50 to 150 cm and are designed with a width of approximately 40 to 80 cm.
  • Correspondingly bent reinforcements are provided on the longitudinal edge area in order to achieve a mutual good connection. Reinforcing lattice girders can also be provided on the top.
  • a supporting scaffold and a working scaffold are required, which will be explained in more detail below using a process sequence.
  • precast concrete slabs By using a combination of precast concrete slabs - of course, precast slabs made of other materials can be used - and an empty scaffolding with slight structural changes to the dome shell, the required scaffolding material can be reduced to an area of an annular section of approx. 5 to 6 m wide.
  • support towers 7 are set up in a ring.
  • annular support structure 8 which is a concentric circle to the container diameter.
  • Radial supports 6 are placed on this support structure 8, which expediently can be adjusted in their curvature according to the curvature of the dome-like cover 2.
  • the other ends of the radial carrier 6 lie directly on the peripheral wall 1 of the container-like structure.
  • symmetrical prefabricated concrete slabs 5 are placed ring by ring in the sense of a pre-shaped but load-bearing formwork.
  • auxiliary beams can be provided, which are arranged between the radial beams 6 running approximately transversely to them. The arrangement of these subcarriers also seals the joints so that concrete cannot escape downwards through the joints.
  • these precast concrete slabs 5 also lie circumferentially closed on corresponding supports (radial supports 6 and auxiliary supports).
  • the concrete 9 is now applied and compacted well.
  • an ring-shaped covering carrier 3 is produced, which must take over the static function of the dome-shaped cover 2 which has not yet been closed.
  • the first annular section A which has now been produced, is stripped off.
  • the structural cover carrier is provided at certain intervals with vertically continuous openings for the passage of fastening means for the radial carrier 6.
  • corresponding suspension devices can also be provided.
  • the outer end of the radial carrier is suspended from this or by means of appropriate fastening means in the area of the pipe bushings.
  • the precast concrete slabs are to be prefabricated on a simple horizontal void. However, they can also be ordered at precast plants at any time.
  • a large-scale auxiliary scaffold for dismantling can be prevented if a light ladder scaffold is moved to the location of the formwork on concentrically arranged rails or on corresponding rollers.
  • a work scaffold is provided which can be walked on or passed over at its upper edge, so that any position on the circumference of the container-like structure can be reached by moving a corresponding mobile pedestal.
  • a support which is curved in accordance with the provided dome curvature or a support which can be adjusted to the curvature and which can be adjusted in accordance with the desired curvatures can be used for the radial support 6.
  • covers for a round container.
  • these covers can also be conical or pyramid-shaped, which will also take place in each case in adaptation to the shape of the container-like structure.
  • the building itself could therefore not only be circular, but also elliptical.
  • the method according to the invention thus considerably facilitates the erection of a dome, cone or pyramid-shaped cover made of concrete for buildings and civil engineering, the advantages achieved not only in the significantly reduced need for formwork and scaffolding material, but also in the significantly reduced workload for erecting the formwork, scaffolding and thus also for erecting such a cover.
