Definitions

  • the invention relates to a turnbuckle device for bracing concrete formwork elements, with two claws and a wedge, the claws being displaceable relative to one another in a bracing direction, the wedge in the turnbuckle device being guided along a wedge guide direction, and the dimension of the advance of the wedge in the turnbuckle device determines the displacement of the claws.
  • a generic turnbuckle device is known for example from DE 35 45 273 A1.
  • Concrete formwork elements are used to erect boundaries for concrete bodies to be cast, such as building walls. In order to obtain pourable limits, several concrete formwork elements usually have to be firmly connected. Turnbuckles are used to connect the concrete formwork elements.
  • the concrete formwork elements essentially consist of a formlining, a frame and struts to stabilize the frame.
  • the turnbuckles are arranged in the area of the crossings of struts and frames.
  • one claw of a turnbuckle engages around a frame section of two concrete formwork elements to be connected, and by means of a wedge the two claws - and thus the concrete formwork elements - are braced against each other, i.e. the claws are moved towards and into one another in a clamping direction.
  • the force of gravity acts on the wedge in such a way that it is pulled in the direction of a stronger bracing.
  • turnbuckle devices are used adjacent to tension the interfaces of two adjacent concrete formwork elements that are subjected to particularly large forces (such as joint corners or outside corners).
  • the turnbuckle devices are then typically arranged on a straight line (e.g. one below the other), each with a parallel line Bracing movements of the claws and parallel movements of the wedges taking place on a single straight line when bracing.
  • Turnbuckle devices must be spaced apart by at least one key length (this is the extent of a wedge in the direction of the wedge guide direction if the wedge is arranged in a turnbuckle device). This limits the number of turnbuckle devices that can be used to secure an interface of two adjacent concrete formwork elements.
  • the object of the present invention is to present a turnbuckle device in which an obstruction of adjacent turnbuckle devices by their wedges can be avoided even with a small spacing of the turnbuckle devices.
  • the wedge guide direction and the bracing include an angle ⁇ less than 90 °.
  • the turnbuckle devices involved span a typically straight boundary line between the concrete formwork elements.
  • the turnbuckle devices are arranged side by side or one above the other on a straight line that runs parallel to this boundary line, the bracing movements of the claws of the turnbuckle devices running parallel to one another.
  • the wedge guide direction according to the invention is not perpendicular to the bracing direction, the wedges with their longitudinal directions are no longer all on a single straight line. Unlike in the prior art, the wedges are not driven for all the wedges along that single straight line, but rather for each wedge on a separate straight line.
  • the distance between the respective straight lines depends on the angle ⁇ and the spacing of the turnbuckle devices. According to the invention, the distance between the respective straight lines is selected such that it speaks to at least one diameter of a wedge (possibly the maximum diameter of a wedge), so that the wedges can no longer come into contact.
  • the bracing direction of advance of the wedges is strictly aligned with gravity in order to secure the wedges against unintentional loosening, for example as a result of vibrations.
  • it is entirely sufficient to have a sufficient vectorial portion of the direction of advance parallel to gravity. Even with a deviation of 45 ° in the direction of the wedge propulsion against the gravity vector 70% of the weight of the wedge is still available to hold the clamping position, corresponding to the sine of 45 °.
  • An embodiment of the turnbuckle device according to the invention is preferred, which is characterized in that the angle ⁇ is between 40 ° and 85 °, in particular approximately 70 °. These angular ranges are particularly suitable for wedge dimensions and concrete formwork element dimensions that are currently in use. The securing effect of gravity is still sufficient.
  • the angle ⁇ is approximately 45 °.
  • the turnbuckle device can be used equally well for connecting horizontally adjacent and vertically adjacent concrete shutter elements, i.e. the turnbuckle can be operated equally well with horizontal or vertical tensioning direction.
  • a position of the turnbuckle device can always be selected in which the wedge is forced into the tightening position by more than 70% of its weight.
  • ⁇ ⁇ 90 ° arctan (B / L) applies to the angle ⁇ , with L: length of the wedge in the wedge guide direction, and B: greatest width of the wedge measured transverse to the wedge guide direction and in the plane of the wedge guide direction and bracing direction.
  • Another preferred embodiment is one in which the wedge is guided through one of the claws alone. This simplifies the guidance of the wedge. The angle ⁇ can then be set very precisely.
  • an advantageous embodiment of the turnbuckle device according to the invention provides that the wedge has at least one depression and / or elevation which extends obliquely to the wedge guide direction, and that at least one of the claws has a profile which engages the depression and / or elevation of the wedge.
  • the profile can be designed, for example, as a row of teeth.
  • Turnbuckle devices profiled in this way can be designed in a wide range of transmission ratios (propulsion versus tensioning path); in particular, they can also be designed well for angles ⁇ less than or equal to 45 °.
  • the wedge has a cross section tapering along the wedge guide direction.
  • the wedge thus decreases in width in the direction of advance.
  • Turnbuckle devices which are based on the effect of the variable external dimension of the wedge, are mechanically particularly simple and therefore inexpensive.
  • a further development of the embodiment with a profiled turnbuckle device is advantageously designed in such a way that the wedge has a constant size, in particular a constant diameter, along the wedge guide direction.
  • the wedge thus maintains its width along the direction of advance. This considerably simplifies the guidance of the wedge in the turnbuckle device, and the angle ⁇ can be set particularly easily and precisely.
  • An embodiment is particularly preferred in which the turnbuckle device can be arranged for mounting on inner hinge corners or outer hinge corners or right-angled outer corners of concrete shell elements. At these positions, particularly large forces are to be expected on the concrete formwork elements, so that the tensioning means to be used must be particularly powerful.
  • a large number of turnbuckle devices can be installed at a short distance from one another, so that large forces can also be handled.
  • a concrete formwork system comprising concrete formwork elements and turnbuckle devices according to the invention of the type described above, wherein the concrete formwork elements each have a plurality of assembly positions, in particular struts, for the turnbuckle devices, the assembly positions of one another in a direction perpendicular to the bracing direction of the at the assembly positions to be assembled turnbuckle devices are spaced at a distance A, characterized in that for the angle ⁇ applies: ⁇ ⁇ 90 ° - arcsin (B / A), with B: greatest width of the wedge measured transverse to the wedge guide direction and in the plane of the wedge guide direction and clamping direction.
  • the wedges can be moved independently of one another in or against the wedge guide direction without the wedges being able to collide.
  • the ends of the wedges are also easily accessible to a fitter.
  • the advantages of the invention are particularly effective when the distance A is less than or approximately equal to the length L of a wedge.
  • the concrete formwork system according to the invention is the only way to make the wedges or turnbuckle devices usable and usable at this distance.
  • a combination of the concrete formwork system according to the invention with the embodiment of the turnbuckle device is particularly preferred, in which ⁇ ⁇ 90 ° arctan (B / L) applies.
  • the lengths of the wedges do not overlap either side, so that particularly easy assembly of the turnbuckle devices is possible due to the free access.
  • bracing direction and the wedge guide direction typically run parallel to the levels of the formwork skins of the concrete formwork elements if the formwork skins have a common plane.
  • a turnbuckle device is also considered to be part of the concept of the invention, in which the wedge guide direction does not run parallel to the level of the formlining, but with the level one
  • angle ⁇ '> 0 ° and preferably 0 ° ⁇ ' ⁇ 10 °. This can be combined with angles ⁇ 90 ° or ⁇ ⁇ 90 °.
  • the angle ⁇ '> 0 ° can also prevent wedges of adjacent turnbuckle devices from colliding. However, the freedom of movement for the wedges is limited by the back of the formlining facing the turnbuckle device.
