Definitions

  • the invention relates to a sliding method for producing building walls made of concrete or the like according to the preamble of claim 1 and a sliding formwork device according to the preamble of claim 7.
  • Comparable sliding methods and slipforming devices are known from AT-PS 23 55 57 and from DE-OS 29 47 210.
  • this prior art relates to the construction of building walls made of concrete with a generally constant wall thickness, wherein aspects of a console production in the context of the sliding process are neither addressed nor can be implemented in the aforementioned prior art.
  • brackets When creating reinforced concrete structures such as television towers, chimneys or the like, it is usually customary to subsequently manufacture individual brackets, line or ring brackets that protrude from the concrete wall in a second operation after the actual building wall has been created using the sliding method.
  • recesses are usually provided for the walls of the building at the appropriate locations during the sliding process, which are set up in a second operation after the sliding process has been completed and the sliding formwork has been dismantled and only then created. This means that the reinforcing bars required for the brackets must be bent sideways or upwards during the actual sliding process and must be bent back into their intended position in the second step. Only then can the consoles be shaped and concreted in their intended form.
  • Individual consoles which are referred to below as block consoles and can have any cross-sectional configurations in horizontal section, such as Rectangle, trapezoidal shape or other polygonal cross-section have the advantage compared to ring or line brackets that they can be erected precisely at the point at which they are required using a suitable sliding method and a suitable sliding shuttering device.
  • the block brackets Compared to "triangular brackets", which initially have a continuous increase in wall thickness in the vertical section of the building wall and then gradually change to a wall thickness reduced in thickness, the block brackets have the advantage of substantially lower concrete consumption.
  • the sliding process for the creation of block consoles is carried out continuously without any significant interruption when sliding up, depending on the design of the sliding formwork device.
  • the object of the invention is therefore to design a sliding method and a sliding formwork device particularly suitable for it so that block consoles can be created individually or in groups in an economical and technically flawless manner even with annular or polygonal structures, which may also be conically tapering and / or inclined .
  • An essential idea of the invention is to equip the sliding formwork on the provided cantilever side of the bracket on the building wall with a formwork form or formwork box as an integral part of the sliding formwork.
  • This formwork form which has a complementary, advantageously at least minimally larger, shape, such as the corresponding block bracket, approximately in the horizontal cross section, is completed at height levels without a block bracket by a formwork apron opposite the adjacent formwork skin. This creates a formwork skin that is continuous in horizontal section and rests against the corresponding outer or inner surface of the building wall.
  • the integration of the formwork for the respective block console with the actual formwork skin of the sliding formwork can be realized in such a way that the formwork form is integrated at the lowest level of the building when the inner and outer sliding formwork is created and is present along the entire height of the building .
  • a formwork skin of the sliding formwork constructed as lamella formwork there is also the possibility of introducing the formwork form with formwork apron into the slat formwork just below the lowest level of the block bracket in the circumferential direction and at the predetermined location of the block bracket to be created — the formwork apron is flush with the adjoining slide formwork in To remove circumferential direction or direction of inclination of the building wall.
  • the formwork form on the wall side is removed when the lowest level of a block bracket to be created is removed by removing the formwork apron, which is held in particular relative to the formwork skin sliding upwards.
  • the entire sliding formwork is raised under the concreting of the corresponding block bracket, whereby a formwork apron is used on the wall side to align the formwork form in such a way that the lower edge of the formwork apron limits the top level of the block bracket or the contact surface of the block bracket.
  • the formwork apron is attached to the rest of the sliding formwork and carried upwards.
  • Corresponding formwork forms for block consoles can be integrated in the outer as well as alternatively or additively in the inner sliding formwork.
  • the form of the form essentially forms a negative form of the console to be designed, the distance between the side surfaces of the form of the form being kept somewhat larger than the width of the corresponding console. In this way it is possible to be able to limit the side flank surfaces of the bracket by side surface formwork inserted into the formwork form.
  • These side surface formworks are advantageously arranged stationary and fixed in relation to the building, while the end face of the bracket is formed by the corresponding formwork skin of the sliding formwork itself or by a formwork surface sliding with it.
  • the side surface formwork can expediently be wooden formwork, which is connected to its stationary arrangement with a bottom formwork delimiting the lower surface of the bracket.
  • the bottom formwork is advantageously suspended for fastening to the building on at least two reinforcing bars, such as steel angle profiles, which protrude from the building.
  • These steel angle profiles can e.g. be welded to the reinforcement bars of the building wall or be an integral part of the wall reinforcement.
  • the reinforcing bars or steel angle profiles of the bracket only protrude inside the bracket and are completely encased when the concrete is brought in.
  • side surface formwork within the formwork form has the advantage that the fresh concrete of the brackets can be removed from the sliding formwork, e.g. forces exerted in the circumferential direction are kept free during its solidification.
  • the side surface formwork designed as stand formwork offers a sufficient air gap e.g. to the steel surfaces of the lamellar formwork of the formwork and can thus be switched off much better.
  • the excess of the formwork forms compared to the final dimensions of the bracket, in particular in the circumferential direction and in depth allows the target dimensions of the bracket to be exactly adhered to by appropriately adapting the side surface formwork used.
  • the lamella formwork of a formwork skin per formwork field consists of one or two mother plates and a large number of intermediate plates provided in the manner of lamellas.
  • the mother sheets have, for example, a 3 to 4 times the width of the width of the intermediate sheets, which e.g. Can be 25 cm wide.
  • the mother plates are preferably made of a relatively thin spring steel and are connected to a yoke in a stationary manner over one or two yoke distances.
  • the intermediate plates suspended from form or guide tubes can be pushed behind the corresponding mother plate by reducing the arc gap between the yokes. If the intermediate plate is completely overlapped by the nut plate provided on the wall, the corresponding intermediate plate can e.g. be removed vertically upwards or downwards from the sliding formwork.
  • the nut plates are at least slightly pretensioned against the intermediate plates in their position of use and pass into them with a flat tapering vertical edge area.
  • the mother plates can also be carried stationary with the corresponding yoke in the circumferential direction and, in addition, can even be detached from the sliding formwork. Due to the butt joint of the vertical edges of the intermediate sheets and the bevel transition on the mother sheets, a largely smooth, continuous formwork skin is created.
  • a change in the diameter of the sliding formwork in the case of annular structures is preferably carried out in the areas outside the formwork for the corresponding block brackets. This is particularly useful where the arc distance between the individual brackets is relatively small, so that the spacing between the brackets is not sufficient for the use of mother plates and / or intermediate plate.
  • the sliding formwork device with a group of adjacent formwork forms for a corresponding number of individual block consoles can e.g. can be used particularly advantageously when creating large chimneys that have a conical taper upwards.
  • the block consoles are required for these chimneys to support the steel or steel concrete platforms, which are usually prefabricated at floor level inside the chimney and which themselves carry flue pipe sections or at least are intended to guide them.
  • the formwork areas between the individual formwork forms are preferably also lamella-like and can be made smaller or larger in the circumferential direction.
  • the platforms to be supported on the block consoles inside a chimney are mostly created with one and the same formwork inside the chimney at floor level.
  • the support axes of these platforms do not run in the radial direction, but e.g. parallel to a main axis of a horizontal plane, e.g. parallel to the 90 ° -270 ° axis. With this design of the support axes of the platforms, these axes run congruently in all planes of elevation. This means that the arc segment distance between the assigned block consoles of a group remains essentially constant, while the angle of the circular arc changes at different height levels.
  • the individual block consoles therefore move in the imaginary development of the chimney surface in a plane along straight lines which do not intersect the extension of the chimney axis, but rather run in pairs parallel but at an inclination corresponding to that of the surface.
  • the line of motion for neighboring block consoles over the total height of a chimney is therefore formed in the floor plan projection by parallel straight lines, the distance between which remains constant.
  • the formwork forms provided for the individual block brackets are kept constant with regard to their distance between the side surfaces and their depth.
  • the same also applies to the maintenance of a largely constant arc segment spacing between the formwork forms of a group of block consoles belonging together, so that changes in diameter of the slip formwork in the area of the slipform formwork lying outside the group of formwork forms are equalized by the displacement of intermediate plates behind the mother plates.
  • Strek - ken of 2-4 m are compensate the associated shuttering forms of block brackets advantageously with a shift and factssencardi positively driven. This can be done both with regard to stationary blocking and with regard to a shift in the circumferential direction due to tension or pressure.
  • This shifting device also serves to improve the adaptation to the corresponding bend or curvature, especially since the arc segment spacing of an assigned group of formwork forms is not to be changed.
  • the displacement device is expediently designed for tension and is articulated to adjacent yokes.
  • overlapping areas of the form and guide tubes of the formwork skin with the guide tubes or guide rails of the sliding formwork area of the formwork forms are provided.
  • the overlap area extends over 1 to 2 yoke fields.
  • the invention makes it possible to create block consoles of the most varied of horizontal cross sections, such as triangles, quadrilaterals, trapezoidal shapes, arch shapes, etc.
  • block brackets by means of the sliding formwork device according to the invention, an inventive idea, which has an independent character, can be seen in the fact that, in addition to automatically adapting a lamella formwork to different diameters, it is also possible to achieve a specific movement of a specific arch segment in the circumferential direction while maintaining the corresponding arch segment length while changing the diameter be introduced into other slipform areas.
  • this glider lungsvorraum compared to known slipform systems are on the one hand, the monolytic and notch-free design of the brackets, the bracket height can be adjusted according to the static requirements.
  • this sliding formwork device allows a continuous simultaneous creation of the block consoles with the building wall.
  • the formwork apron is also suitable for the formwork apron to be designed as steel sheet lamellae by means of a plurality of lined-up butt-jointing intermediate sheets. As soon as the formwork aprons have reached the same height as the sliding formwork, they can be attached to the sliding formwork and lifted up to the next higher bracket level as part of the sliding formwork. This creates smooth wall surfaces that do not differ in any way from the surrounding wall surfaces of the building.
  • a slipform device 1 is shown schematically and in a partial section on a building wall 13 which has been built essentially vertically using the sliding method.
  • the slipform device 1 has a plurality of outer yokes 21 and inner yokes 22, which are usually supported at their lower ends by support rollers 29 against the solidified concrete wall. These support rollers 29 are omitted in the inner yokes 22 in the area of the block consoles to be executed, since they would be ineffective because of the yoke distance from the concrete wall.

  • the upper ends are in force engagement with a support grate spanning the structure horizontally beyond its diameter.
  • the yokes 21 and 22 are non-positively connected to one another via two crossbeams, of which the lower one is shown as a yoke support 23 and, for example, with regard to their distance. adjustable via traverse spindles 54.

  • the sliding formwork 4 has a lamella-like formwork skin 6 oriented towards the concrete wall, a formwork skin 7 being provided on the opposite side for shaping the inner surface 14.
  • the lamella-like formwork is supported on the yoke frame, displacements in the circumferential direction are possible due to changes in the diameter of the structure.
  • working platforms 31 are provided on both sides of the building wall on different levels, which can be rigidly and articulatedly connected to the yoke frame.
  • a particular problem in the design of the slipform device 1 for conically tapering and / or additionally inclined structures is where the block brackets 15 or 16 to be created are required in groups and the arc segment distance between the block brackets and over the entire extent of the group at all height levels of the building should be kept at least largely constant to constant.

  • this block bracket 16 or the block bracket, not shown opposite it, mirror-symmetrical to the axis 26, would move inward on the corresponding radius with the circular arc angle a to the axis 27.
  • the support axes 42 and 43 running parallel to the transverse axis 27 for platforms manufactured in the building and to be supported on the brackets there is, however, the peculiarity that the group of block brackets 15 to 18 also has the same arc segment spacing at a height level of the building with a smaller inner diameter should maintain.
  • the block console 16 arranged in the left half does not appear at a higher level as a hatched block console 36 'at the same circular arc angle a, but that the mirror-image counterpart to the block console 16 is the block console 36 arranged at an angle ⁇ to the transverse axis 27.
  • the arc segment distance between the individual block brackets 15 and 16 or the total arc distance between the outer side surfaces 19 and 20 of the block brackets 16 and 18 therefore remains constant over the total height of the structure, so that the circumferential reduction of the slipforming device with this requirement in the slipforming area outside of Group of block consoles by overlapping sliding of the intermediate plates behind the corresponding mother plates.
