Definitions

  • the invention relates to an internal formwork for rotationally symmetrical structures with a plurality of formwork rings arranged one above the other, made of interconnected, preferably made of sheet steel, formwork panels that are bendable in the circumferential direction of the rotationally symmetrical structure, with stiffening rings consisting of ring segments which describe a ring in the form of a polygon for the formwork panels and with at least one spreading device arranged between the ring segments.
  • stiffening rings consisting of ring segments which describe a ring in the form of a polygon for the formwork panels and with at least one spreading device arranged between the ring segments.
  • each formwork panel has to be curved for a certain building diameter. If several buildings with different diameters are to be boarded, a corresponding number of formwork panels must be available.
  • the object of the invention is to provide an internal formwork of the type mentioned, in which cheaper formwork elements can be used and in which the formwork panels can be adapted to all common building diameters, so that cylinder structures with different diameters can be interconnected with the same panels. It should be ensured that the formwork rings are exactly circular.
  • the formwork panels are tensioned on the stiffening rings, that vertical U-rails, which bear the spreader and bear on the formwork panels and carry the spreader device, are arranged between the ring segments such that the U-rails are arranged over at least two stiffening rings extend and that the formwork rings are attached to the U-rails.
  • An embodiment of the invention provides that a U-rail is arranged over the circumference of the formwork rings after each formwork panel.
  • formwork panels have fastening flanges at their vertical edges, which are arranged at a distance from the vertical edge that is equal to half the width of the U-rail. In this way, the vertical edges of the formwork panels meet flush.
  • the spreading device has a clamping screw which is held against rotation at the end of a ring segment, and a clamping nut which is supported indirectly or directly at the end of the second ring segment.
  • An embodiment has proven particularly useful in which the clamping nut is supported directly on the U-rail, the U-rails having holes in one of the side webs through which the clamping screws protrude, and guide bushes projecting into the U-rail on the other side web the clamping screw on which the clamping nuts are supported.
  • the guide bushings are advantageously welded to the U-rails.
  • Another exemplary embodiment of the invention provides that the end of a ring segment opposite the clamping screw is fastened to the U-rail by means of a retaining bolt.
  • FIG. 1 schematically shows a formwork according to the invention, partly in section, FIG. 2 shows view I of FIG. 1, FIG. 3 shows section AA of FIG. 2, and FIG. 4 shows section BB of FIG. 2nd
  • the formlining hangs on the outside on horizontal bi-steel rings 17, which are supported by the vertical steel profile beams.
  • Bi-steel has proven to be particularly suitable, but a different strip steel, a flat iron, and possibly also a round steel could also be used.
  • the inner formwork like the outer formwork, consists of formwork rings 1, which are formed by the formwork panels 3.
  • Joint cover strips 2 can be provided on the ring joints between the formwork rings 1. However, the joint cover strips 2 will rather be dispensed with in the internal formwork, since there is no visible surface here in the concrete wall to be produced.
  • stiffening rings 18 are provided, which are advantageously composed of ring segments 21, which are formed by shaped tubes, square tubes in the exemplary embodiment.
  • the stiffening rings 18 are dimensionally stable.
  • U-rails 19 are provided at the junctures of adjoining formwork panels 3.
  • the U-rails 19 are two meters long, ie one U-rail 19 extends over four formwork rings 1.
  • the formwork panels 3 are also provided with angle brackets 4 at their vertical edges 3 ', but these are set back by a dimension r with respect to the edge 3' (FIG. 4).
  • the dimension r corresponds to half of the middle connecting web 19 ′ of the U-rail 19.
  • the angle iron 4 of adjacent formwork panels 3 are not directly connected to one another, but indirectly via the U-rail 19.
  • Wedge locks 10 are provided, each of which comprises the free web 4 'of the angle iron 4 and a free side web 19 "of the U-rail 19, which form connecting flanges.
  • the wedge locks 10 have a guide groove in which the mounting position of the wedges 13 is arranged. The wedges 13 are driven into the wedge locks 10.
  • the stiffening rings 18 are loose with respect to the formwork panels 3, but are connected to the U-rails 19.
  • Wedge locks 10 ' hold the stiffening rings 18 on the U-rails 19.
  • Wedges 13' are hammered into the wedge locks 10 '.
  • Each ring segment 21, which is advantageously formed by a shaped tube, is provided at its ends with a cover plate 22, a cover plate 22 receiving a retaining bolt 23 which, in the installed position, projects into a hole in one of the side webs 19 ′′ of the U-rail 19.
  • the cover plate 22 is provided with an Allen key 25 in which the head 26 of a clamping screw 27 is held.
  • the clamping screw 27 projects freely through a hole 28 in the second side web 19 ′′ of the U-rail 19 into a guide bushing 29 welded onto the U-rail 19.
  • a clamping nut 30 for the clamping screw 27 is arranged on the guide bushing 29.
  • adjacent ring segments 21 can be pressed apart by turning the clamping nut 30 by means of the clamping screw 27. Since this results in an increase in diameter, the ring segments 21 press against the formwork ring 1 formed by the formwork panels 3 and the formwork ring 1 is stiffened, which is also formed in an exactly circular manner.
  • FIG. 3 also shows a vertical support 31 formed by a double-T beam, which is connected to ring segments 21 arranged one above the other by means of a wedge lock 10 'and a wedge 13' and thus stabilizes the formwork.
  • Three or more vertical supports 31 are advantageously provided per formwork.

Abstract

Procédé de coffrage ainsi que coffrage intérieur et extérieur et pièces de liaison utilisés pour l'érection de constructions circulaires, par exemple des constructions cylindriques ou sphériques. Selon le procédé on érige une surface de coffrage (2) ayant la hauteur de la paroi à couler. Ensuite les armatures sont mises en place et on tire vers le haut la deuxième surface (2) de coffrage par étape de 50 cm, en introduisant le béton à chaque levée du coffrage. Les coffrages (2) sont constitués d'anneaux de tôles souples. Les anneaux sont tendus pour constituer une forme stable. Les tôles sont maintenus ensemble par des assemblages à clavettes comportant de coins rétractables entre les supports et les brides de liaison des tôles.
