  • the support element may be, for example, one or more substantially annularly arranged around the opening and / or on the fastening device itself intended to act elements on which the lifting and mounting device can be pivotally supported in the manner described.
  • the movement of the tension member always occurs to the final fastening position, namely to the opening of the fastening device.
  • the tensioner head attached to the tension member may be disposed on the attachment device such that the fastening bolt is easily secured can be inserted.
  • the power transmission between the lifting device and the tension member can take place directly on the tensioner head, so that the hitherto required reworking can be omitted at the nip of the tension member.
  • the at least one support element can advantageously be provided so that it can be received between the tensioner head and the fastening device, so that it can remain permanently and optically "hidden” on the fastening device, and requires no complicated measures for the removal of auxiliary straps or the like are.
  • the invention relates to structures in which one or more tension members in the final state are "free", i. not surrounded by concrete or the like, remain.
  • the fastening device can also be referred to as a tab or perforated plate.
  • At least one support surface is provided arcuate.
  • the arc may, for example, be essentially semicircular, and the region of the lifting and mounting device according to the invention, on which the support surface is provided, can describe a part of a circular ring, for example a semicircular ring, as a whole. In that regard, this area can also be described as U-shaped or "sickle-shaped".
  • the support of the lifting and mounting device to the fastening device of the building when the lifting and mounting device is fork-shaped in the region of the support surface designed.
  • a gap in which, for example, the fastening device can be received in the form of a provided with an opening stable sheet In this way, a particularly torque-poor support of the lifting and mounting device.
  • the lifting and mounting device further comprises at least one connection for at least one auxiliary tension member, which is articulated to the region of the support surfaces.
  • the pivot axis of the lifting and mounting device about the opening of the fastening device may be substantially perpendicular to a plane containing the pivot axis of the Hilfszugglieds connection to the area with the support surfaces, so that the lifting and mounting device in this area a total "gimbal "represents.
  • the lifting and mounting device according to the invention comprises at least one such auxiliary tension member, as e.g. a rope or a strand which in particular may have a length which extends from the fixing device provided for the rope at least to the ground.
  • auxiliary tension member as e.g. a rope or a strand which in particular may have a length which extends from the fixing device provided for the rope at least to the ground.
  • the lifting and mounting device preferably further comprises a lifting device, for example in the form of a hydraulic device, which cooperates with at least one auxiliary tension member and absorbs the tension member with at least one tension member head such that the tension member directly to the fastening device to which it the tensioner head is to install, is feasible.
  • a lifting device for example in the form of a hydraulic device, which cooperates with at least one auxiliary tension member and absorbs the tension member with at least one tension member head such that the tension member directly to the fastening device to which it the tensioner head is to install, is feasible.
  • the movement of the tension member takes place directly and directly to the attachment point described, so that no complicated clamping or bending measures are required to bring the tension member head in the required position.
  • the invention further proposes the use of at least one support element, which is provided on a fastening device for a tension member of a building with at least one tension member head in the vicinity of at least one opening of the fastening device, can remain on this and preferably between the fastening device and a tension member head is receivable for support a lifting and mounting device for tensioning the tension member before.
