Definitions

  • Fastening device for building formwork mounting arrangement with such and method for assembling and dismantling of building formwork
  • the invention relates to a fastening device for structural formwork, a fastening arrangement with a spacer and at least one such fastening device, and method for assembling and dismantling a building formwork according to the respective independent claims.
  • bar clamping systems are used, which have a variety of applications, such as the prestressing of concrete elements or the support of building formwork.
  • Such bar clamping systems are also called shutter anchors.
  • the bar clamping systems are used for the positioning of shuttering parts, which define the dimensions of the concrete wall to be built.
  • four vertical shuttering panels are constructed rectangular, with two opposite plates are held by spacers in a defined distance from each other.
  • the bar clamping systems exist in an exemplary, simple embodiment of an anchor rod which is arranged between the shuttering parts and projects through this, and from a respective threaded nut on each outer side of the shuttering parts, by which the shuttering parts are brought by tightening the nuts to the anchor rod to the required distance from each other .
  • the anchor rod is partially surrounded by a rigid, cylindrical spacer, which ensures that the shuttering parts can not be screwed too close to each other.
  • the anchor rod for example a Dywidag® anchor rod, has a coarse thread running the full length.
  • the procedure is such that the shuttering parts are initially positioned and fixed as described by means of the bar clamping system.
  • Connecting pipe can be poured into the interior defined in this way between the concrete facing parts.
  • the casings can be removed by unscrewing nuts attached to the tie rod ends.
  • the threaded rods can also be pulled out, but the spacers remain in the concrete.
  • the threaded rods must be displaced after removal, e.g. To extend the wall further in width, so that the procedure described repeated.
  • a disadvantage of this method is the time-consuming assembly or disassembly of the formwork.
  • EP1854941 A2 proposes a tensioning device with a main body and a nut consisting of two halves.
  • the two halves together form an internal thread and are arranged within the main body.
  • the halves are thereby held in the release position, that is acted upon manually against a spring force which presses the halves in the direction of the engagement position.
  • By releasing the halves between the release position and the engaged position are movable, in they engage in an external thread of an anchor rod.
  • the body runs conically inside. Accordingly, the halves together have a conical outer contour.
  • a disadvantage of this solution is that the tensioning device in the tightened state on the wall formwork can be released from the engagement position only by difficult turning of the entire tensioning device.
  • Another disadvantage is that a force is necessary to push the clamping device on the anchor rod, since in this process, the clamping device must always be kept in the release position.
  • the object of the invention is therefore to provide a possibility for shortening the dismantling time of formwork and overcoming disadvantages of existing fastening devices. This object is achieved with a fastening device and a fastening arrangement according to the respective independent claims.
