Definitions

  • the invention relates to a formwork for erecting buildings with any layout, any generators and possibly variable wall thickness, consisting of a formwork for an interior and / or exterior formwork and several, in the horizontal direction overlapping Schalplat th.
  • a sliding formwork for the manufacture of such structures has already become known, in which lifting jacks are provided on horizontal guides that can be moved transversely to the wall, and a formwork that is variable in length and adjustable transversely to the wall.
  • These jacks are designed similar to a parallelogram with articulated corner points, so that the horizontally running part of the jacks are always arranged horizontally and the other parts of these jacks run parallel to the inclined wall. So there is a rather complicated adjustment of the formwork inclination, since all jack stands to be arranged on the circumference of the formwork must each be set to the corresponding inclination. In addition, it must be noted that all these jack stands hang together with the formwork on a concrete platform, so that not only the onward transport, but also the new adjustment of each section of the structure are associated with particular difficulties.
  • the present invention has therefore set itself the task of creating an exactly and easily adjustable formwork, which can be adapted after each building section a changed inclinations, changed wall thicknesses, etc.
  • this is achieved in that the inner and / or the outer formwork are assigned circumferentially closed, force-dissipating support rings at a horizontal distance therefrom, in which threaded spindles are held displaceably in an approximately horizontal direction, but lockable, the ends of which are held at the ends
  • Formwork panels or to formwork straps that are in contact with the formwork panels, and that between the formwork panels, seen in the circumferential direction of the formwork, the formwork panel edges are provided on the rear side of the overlapping filler pieces, the filler pieces on their building surface in the area between the side edges of the each with a spacing between successive formwork panels approximately the thickness of the formwork plates have appropriate support.
  • the formwork according to the invention can be used without anchoring the structure, since the formwork only has to be supported in the vertical direction.
  • the supporting rings conduct the force a emanating from the formwork, so that a mutual connection of the outer and inner formwork, which penetrates the structure, is not required, as in the known formwork.
  • FIG. 1 shows a section through a formwork according to the invention, an inner and / or an outer casing being shown; 2 shows a plan view of such formwork in a ring-shaped structure;
  • Figure 3 is a plan view of an inner support ring.
  • Figure 4 is a plan view of a portion of an outer support ring. 5 shows a section along the line I - I in Fig. 4.
  • FIG. 6 shows a section along the line II-II in FIG. 4, shown enlarged compared to FIG. 4;
  • FIG. 7 shows a partial section of the inner formwork with the lower section of a support ring
  • FIG. 8 shows an enlarged representation compared to FIG. 1 of an angular support part to be arranged on a building section that has already been produced
  • FIG. 9 shows a front view of the support part according to FIG. 8.
  • 10 shows a plan view of a formwork panel with a formwork support attached thereto; 11 shows a front view of this formwork panel;
  • FIGS. 10 to 12 shows a side view of this formwork panel; 13 to 15 a filler corresponding to the representations in FIGS. 10 to 12;
  • FIG. 16 shows a support part for an inner podium in a top view, the use of a conical structure being shown in the lowermost area and in the uppermost area;
  • FIGS. 1 and 2 The formwork shown in FIGS. 1 and 2 is intended for the erection of a structure which is ring-shaped in cross section, this structure tapering upwards in the shape of a truncated cone or truncated cone and, moreover, the wall thickness of the structure decreasing towards the top.
  • An embodiment is also described in the drawings, in which the horizontal generators form circular arcs. It would also be conceivable to use such formwork for any cross-sectional shape of a building, for any generators and for variable wall thickness.
  • An inner formwork 1 and an outer formwork 2 are therefore provided here, with a formwork scaffold composed of several parts, which will be explained in more detail, and several in a horizontal direction comprehensive formwork panels 3 and 4 are provided.
  • Both the inner formwork and the outer formwork 2 are assigned at a horizontal distance from them circumferentially closed support rings 5 and 6, in which threaded spindles 7, 8, 9 and 10 are held in an approximately ho zontal direction. The free end of this thread spindles 7 to 10 engages the formwork panel 3, 4 or the formwork supports 11, 12a which are in contact with the formwork panels 3, 4
  • formwork panel edges are provided on the back of the overlapping filler pieces 13, 1, the filler pieces 13, 14 on their surface on the building side in the area between the side edges of the formwork panels 3 or spaced one after the other 4 have a support 15, 16 corresponding approximately to the thickness of the formwork panels 3, 4.
  • the formwork panels 3, 4 are supported by approximately vertically running formwork supports 11, 12 on the floor or on building sections 17 that have already been manufactured.
  • the support is provided on the floor or on a corresponding substructure, with the construction of the next building sections in each case Cladding tubes 18 are used, where with appropriate screw connections in the area of these cladding tubes 18 angular support parts 19, 20 can be attached to the manufactured sections of the building who can.
  • the formwork panels 3, 4 can therefore be supported on the angular support members 19, 20 via the formwork supports 11, 12. It is sufficient to provide such a support for each formwork panel, with extension pieces 21, 22 being fastened, for example screwed, to the corresponding formwork supports 11, 12 on the underside.
  • the remaining formwork supports 23 and 24 which follow one another at the required distance do not necessarily have to be supported by such support members 19, 20, but it would also be possible for these remaining formwork supports 23, 24 to provide such supports.
  • the angular support parts 19, 20 have a U-shaped, upwardly widening insertion opening 25 so that the formwork supports or their extension pieces 21, 22 can be introduced more easily and are also against lateral shifting.
  • the formwork supports 11, 12 or their extension pieces 21, 22 have an adjustable support part 26, 27 on their underside, which is attached to the angular support parts 19 , 290 lies on.
  • This support part 26, 27 is expediently designed as a threaded spindle, for example as a screw. It is therefore possible to easily adjust the height of the formwork girder and thus also the formwork panels to the required setting.
  • the support rings 5 and 6 are formed from two rails 30, 31 which run parallel and at a distance from one another and which are connected to one another via struts 32. These struts 32 can be formed in a simple manner by uprights. With correspondingly larger support rings, additional struts can also be provided.
  • Sleeves 35 exist. These sleeves 35 serve to push the threaded spindles 7 to 10.
  • Such flat profiles 33, 34 can be bent in a circular manner in a simple manner, so that the support rings 5, 6 are formed.
  • the inner support ring 5, which is therefore assigned to the inner formwork 1 can be manufactured in one piece, whereas the outer support ring 6, which is assigned to the outer formwork 2, is expediently made from a plurality of curved sections, which at their joints in the area of the two rails 30, 31 are mutually connected.
  • flanges 36 can be provided, with threaded sleeves 37 or corresponding through-holes being assigned to these flanges, which enable mutual screwing at the butt joints. It is also possible to assemble the inner support ring 5 from a plurality of such arc sections.
  • the formwork supports 11, 12, 23, 24 are advantageously designed as I-beams, w in the case of a cross leg 37 adjoining the formwork panel 4 or the filler 14 and 38 threaded sleeves or nuts 39 on the opposite cross leg for receiving one end of the threaded spindle 7 to 10 are arranged.
  • the arrangement of these formwork beams over the entire height of the formwork panels 4 and 14 enables proper load distribution, so that for a precise adjustment of the inclination of the formwork panel or wall thickness, only two threaded spindles 7, 8 and 9 arranged one above the other, 10 must be used in the corresponding nuts 39 or threaded sleeves, the threaded spindles 7, 8 or 9, 10 being guided through the sleeves 35 in the support rings 5, 6.
  • the threaded pins 45 are expediently designed as countersunk screws inserted into the formwork panels 3, 4 and freely projecting to the rear, so that there is an inner, flat surface with the formwork panels 3, 4.
  • Spacer webs 47 are inserted between the formwork beams 11, 12 and the filler pieces 14, 15 and the sheet 3, 4, which are in the area of the
  • Slits 46 or the threaded pin 45 are interrupted. These interruptions are practically only required for the filler pieces 14, 15, whereby these interruptions, with correspondingly larger overlaps of the successive formwork panels and filler pieces, allow the threaded pins 45 or correspondingly arranged flanges to be pushed through underneath the formwork supports 11, 12 without hindrance.
  • the filler pieces 14, 15 have a support 15, 16 facing the building section, the thickness of which corresponds approximately to the thickness of the formwork sheets 3, 4.
  • the support 15, 16 is advantageously made of a material that can be separated according to the increasing coverage area of the formwork panels 3, 4 and the filler pieces 13, 14.
  • the support 15, 16 can be made from individual pieces, which are respectively narrow or br ⁇ it ⁇ for the construction progress, from the filler 13, 14 separable strips of metal or plastic are formed, with corresponding strips being removed at each edge of the support 15, 16 after each new set-up of the formwork for a further section of the building.

  • the required area can be separated by appropriate cutting tools, so that the separated area of the support 15, 16 can be removed from the filler.
  • the formwork panels 3 can be made rectangular in their development, whereby the conicity in conical or truncated cone-shaped or pyramid-shaped structures can be achieved solely by the acute-angled overlap by the fillers 13, 14
  • the formwork panels 3 can be made rectangular in their development, whereby the conicity in conical or truncated cone-shaped or pyramid-shaped structures can be achieved solely by the acute-angled overlap by the fillers 13, 14
  • the support ring 5 associated with the inner formwork 1 carries a solder cross 50, from which a solder protrudes onto an underlying inner surface 51 supported on the angular support parts 19, 20. It is thus possible in a simple manner to check the exact vertical orientation of the building during the entire construction step. It is therefore already necessary to divide the formwork in accordance with the vertical construction progress.

Abstract

Dans un coffrage destiné à l'édification d'ouvrages à plan d'ensemble et génératrices quelconques et éventuellement épaisseur de paroi variable, il est prévu un coffrage intérieur (1) et un coffrage extérieur (2). Des bagues d'appui (5, 6) à fermeture circonférentielle sont adjointes à la fois au coffrage intérieur et au coffrage extérieur, à distance horizontale de ceux-ci, ces bagues d'appui (5, 6) comportant des douilles (35) orientées radialement, dans lesquelles sont supportées, coulissantes mais bloquables, des tiges filetées (7, 8). Ces dernières s'appliquent, à l'une de leurs extrémités, sur des supports de coffrage (11, 12) adjacents aux plaques de coffrage (3, 4). On peut ainsi régler l'inclinaison des plaques de coffrage (3, 4) ou l'épaisseur de paroi de l'ouvrage à édifier. Entre les plaques de coffrage (3, 4) sont disposées, vues dans le sens circonférentiel du coffrage, des pièces intermédiaires (13, 14) recouvrant la face envers des bords des plaques de coffrage. Ces pièces intermédiaires présentent, sur leur surface côté ouvrage, dans la région située entre les bords latéraux des plaques de coffrage (3, 4) se succédant respectivement à distance, un élément rapporté (15, 16) correspondant approximativement à l'épaisseur des plaques de coffrage (3, 4).
