Definitions

  • the invention relates to a method for the erection of castable materials, in particular concrete structures, in particular of circumferentially closed structures with a reusable formwork and this formwork has an inner formwork and / or an outer formwork and both formworks upright, spaced apart, in the longitudinal direction has one-part or multi-part supports and formwork panels lie between the supports and are anchored to them, and the supports are supported by tension and / or compression elements running transversely to their longitudinal extension, and the formwork panels can be inserted or removed at right angles to their plane between the supports , and a device for exercising the same.
  • the formwork rings mentioned can often no longer be used, so that it is necessary to use conventional formwork methods and formwork means which work with beams and formwork panels of conventional design.
  • the invention now aims to propose a method which can be used with relatively little effort in terms of formwork, although essentially conventional formwork elements (beams, formwork panels) are used and the structures to be manufactured are extremely large.
  • this is achieved by erecting the supports of the inner formwork and / or the outer formwork and then using formwork panels up to a height which corresponds to only a fraction of the height of the structure to be produced, whereupon the formwork cavity thus formed is filled and after Setting the poured-in material, the formwork panels underneath the top row of formwork panels are loosened and removed and then placed on the remaining formwork panels and connected to the carrier, after which the formwork cavity thus formed is filled and, after the cast-in material has set, the process described (implementation of the Formwork panels) is repeated until the height of the building is reached. Thanks to this proposal, it is possible to erect penetration-free structures with large expanses and with a relatively modest amount of formwork.
  • FIG. 1 shows a vertical section through a formwork for a round container with already introduced concrete
  • 2 shows the formwork according to FIG. 1, but already in a second step of the method
  • 3 shows a detailed top view of the formwork according to FIG. 1
  • Fig. 4 is a formwork in plan view, the outer formwork and inner formwork have a different structure
  • 5 shows a detail from FIG. 3, but on an enlarged scale compared to this
  • FIG. 6, 7 and 8 show in detail the expansion body in a side view for transmitting the forces from the upright support to the pressure or tension members
  • 9 shows a tool for moving the upright support
  • Figures 10 and 11 illustrate beam connections
  • 12 shows a variant of the support structure and formwork panels used for the formwork
  • Fig. 13 shows a carrier in detail.
  • the formwork according to FIG. 1 for the erection of a cylindrical round container consists of an outer formwork 1 and an inner formwork 2.
  • the outer formwork 1 has upright I-beams 3, for example profiled roller beams or wooden beams, to whose outwardly facing flange 4 support brackets 5 are fastened.
  • These upright beams 3 can extend in one piece over the entire height of the building to be erected, but they can also be divided over this height and consist of individual beams of the same or different lengths, which are firmly connected to one another and aligned.
  • the brackets or supports 5 are designed to be pivotable upward (FIG. 13). They consist of a right-angled triangle, the pivot axis 31 being in the corner of the right angle. A raised edge 32 prevents the pressure or. Tension member.
  • the support surface of the support can be enlarged by a bar 30 welded on the edge. Stops 34, which encompass the pedestal 35 laterally, ensure the correct position when the support is pivoted in (dashed line in FIG. 13).
  • the formwork panels 7 are attached to the inner flanges 6 of the beams 3. These expediently consist of glued wooden panels and are rebate-like at the edges, the formwork panels 7 with their rebated edges resting against the back of the inner flange 6 of the girder 3, the depth of the paragraph-like fold being dimensioned such that those facing the structure to be manufactured Surfaces of the formwork panel 7 and the flange 6 are approximately flush with each other. In this position, the formwork panel 7 is held by a wedge or an expansion spar 8, which is clamped between the outer flange 4 and the formwork panel 7. As a rule, several such spars 8 are inserted over the height H of a formwork panel 7, but at least one spar (FIG. 5).
  • FIG. 4 Another assignment of formwork panel 7 and support 3 is shown in FIG. 4 in connection with the outer formwork 1.
  • the formwork panels 7 lie here with their edges on the flanges of the support 3.
  • these panels On the back, these panels have holding members 36 in their edge area, which are hooked onto the flanges of the supports 3 and which can possibly be additionally braced with wedges 37.
  • the outer formwork 1 (Fig. 1) can be created up to the height of the building to be manufactured.
  • the flanges 4 of the supports 3 have brackets 5, on which ring-shaped tension members 9 rest, which have the task of absorbing the forces acting on the formwork when filling with concrete, for example in the manner of a barrel tire.
  • these tension members 9 consist of I-beams which are joined to form a ring. This ring can be assembled from individual straight partial carriers or from partial carriers that are already curved in themselves.
  • expansion members are used, which are shown in FIGS. 6, 7 and 8 in a side view. 6 is a type of toggle lever 38 which is pivotally mounted on a pair of tabs 39. Since the one tab 39 'has several rows of holes, the length L of the expansion member can be adapted to the particular formwork conditions.
  • Fig. 6 shows the expansion member in the released position. To tension the expansion member, the lever 38 is pivoted counterclockwise, so that the cam rigidly connected to this lever rests on the pressure or tension member.
  • FIG. 6 is a type of toggle lever 38 which is pivotally mounted on a pair of tabs 39. Since the one tab 39 'has several rows of holes, the length L of the expansion member can be adapted to the particular formwork conditions.
  • Fig. 6 shows the expansion member in the released position.
  • the lever 38 is pivoted counterclockwise, so that the cam rigidly connected to this lever rests on the pressure or tension member.
  • the expansion member is designed as a threaded spindle 4 with a left-hand and a right-hand thread and with two jaws 46 and 47, which bear against the components to be supported against one another.
  • This spreader is infinitely adjustable.
  • a wedge 41 instead of a toggle lever 38 according to FIG. 6, a wedge 41 has entered which cooperates here with an expansion body 42 from a plate assembly. With such spreading members, the formwork can also be pre-stressed.
  • expansion bars can also be used in simply mounted cases, as was described, for example, in connection with FIG. 5.
  • the upright beams 10 of the inner formwork are then set up, which are designed in the same way as the beams 3 of the outer formwork described above.
  • These supports 10 can also extend in one piece over the height of the structure to be manufactured or can be formed in several parts over this height.
  • the concrete is poured in up to the area of the upper edge 13 of the top row of formwork panels 7 '. If the filled-in concrete has set and has achieved sufficient strength, the expansion members 41-42 of the lowest pressure ring 12 are then released and the pressure ring 12 is lifted out. Then the formwork panels 7 of the lower row are loosened, removed and then placed on the upper edge 13 of the originally top row of formwork panels 7 'and connected to the carriers 10 in the manner described above and fastened to them. A second ring of formwork panels 7 "is inserted. The lower pressure element 12 is set up, namely on the brackets 5 (FIG. 2) that follow the originally top pressure element 12, so that a formwork state is subsequently achieved, as shown in FIG.
  • the beams 10 of the inner formwork 2 are formed in one piece, they remain in their original position, as can be seen from FIGS. 1 and 2, only the pressure or tension members 12 and the formwork panels 7, 7 'and 7 "of the inner formwork
  • the girders are made up of several parts, that is, made up of several individual girders in the longitudinal direction, the bottom sub-girders can be removed when the formwork panels are moved and the tension and pressure elements or formwork panels can be implemented , which are under tension after the concrete has been poured in, hold the formwork panels against the floor 16 even without further vertical support, in which case, in order to increase safety, expediently wedge-shaped on the inside flanges 6 '(FIG.
  • Lugs 17 are provided which jump directly into the concrete and prevent the formwork construction from slipping.
  • the individual short carriers 10 ' are firmly connected to one another via tabs 18 and screws 19.
  • at least one end face 20 is expediently slightly beveled, which facilitates the removal of the carrier when the individual elements are moved. It is within the scope of the claimed method to implement only a few of the upright supports which follow one another in the circumferential direction with the formwork panels.
  • connection point of two short beams 10 ' can be designed so that successive beams can be arranged at an angle to one another (FIG. 11), the corresponding flange 18' being adapted to this angular shape.
  • This enables the formwork to be set down in its height and thus to form angled sections, so that masonry is or can be erected that has surface sections that deviate from the vertical.
  • An auxiliary device as shown in FIG. 9, can be used to move the short beams 10 ′ during the gradual and gradual lifting of the formwork.
  • This is a kind of pendulum 43 with an upper hook 44, which is attached to the pressure member 12.
  • a gripping tab 45 At the lower end of the pendulum is a gripping tab 45 which can be attached to the support to be moved.
  • the released beam hangs on this pendulum 43 (dashed lines in FIG. 9) and can then be pulled up and used in the sense of the progressive formwork construction described above.
  • the outer formwork can be erected up to the planned height of the structure to be manufactured, and the inner formwork is then gradually implemented and raised in accordance with the construction progress.
  • the inner formwork is then gradually implemented and raised in accordance with the construction progress.
  • the supports arranged upright in the exemplary embodiment shown are to be arranged obliquely inclined in the case of a conical structure, the supports then lying parallel to the generatrix of the conical jacket. Because of this inclined arrangement to form a formwork for a conical structure, the distance between two adjacent beams changes depending on their longitudinal course. With such formwork, it is therefore not readily possible to use the conversion method described above, since the formwork panels of adjacent rows of formwork panels must have different widths.
  • brackets 5 have always been shown so that their support surface for the annular pressure or tension members 9 and 12 are perpendicular to the longitudinal axis of the carrier 3 and 10 or take this position by themselves if they are lifted and in the Sequence are released (Fig. 13). It is expedient to design these brackets in such a way that they can be brought into any angular position with respect to the longitudinal axis of the supports 3 and 10 and can be fixed in this position. About at for example, curved elongated holes in connection with clamping screws, this can be achieved without any problems. Thanks to this configuration of the brackets, it is possible to align the brackets in the case of inclined supports 3 and 10 such that they form horizontal support surfaces for the tension or compression members despite the inclined position of the supports mentioned.
  • brackets 5 it is expedient to provide the respective outer flanges of the supports 3 and 10 with rows of holes and to screw the brackets 5 to the flanges of these supports via mounting plates. Thanks to the rows of holes running along the length of the beams, these brackets 5 can then be installed at any point, which increases the adaptability of the formwork elements.
  • the formwork panels 7, which are shown in FIGS. 3 and 4 as flat panels, can also be drawn.
