  • the invention relates to a tensioning device according to the preamble of claim 1 . Furthermore, the invention relates to a clamping system according to the preamble of claim 12. Finally, the invention relates to a method for handling a clamping device according to the preamble of claim 13.
  • the tabletops In many production areas and especially in metal and mechanical engineering, special work tables are used, for example as work, welding or assembly tables. In order to be able to attach the various workpieces, tools and holders firmly and securely to the table, the tabletops must be prepared in a suitable manner. As a tabletop, the perforated plate is aligned at least essentially horizontally. However, such perforated plates can also be aligned in other installation situations, for example vertically or at any other desired angle to the horizontal, optionally also adjustable.
  • the table tops are designed as so-called perforated panels or perforated table tops. This means that the table top or perforated plate has a certain number, depending on the application, even a large number of holes. These holes are typically arranged regularly, that is to say in particular at equal intervals.
  • the holes are mostly openings, ie continuous holes.
  • the holes are usually designed as circular or cylindrical bores. However, they can also be provided, at least in part, as oblong holes, that is to say as slit-shaped openings.

  • clamping devices have a central clamping bolt or retaining bolt that is inserted through the respective hole in the perforated plate.
  • the retaining bolt typically has a washer as a counter-retaining element or counter-retaining element.
  • the counter-holding element rests on the perforated plate.
  • another washer may have to be screwed to the retaining bolt from below the table top with a nut. This means that high holding torques can be achieved. To do this, however, you have to work from underneath the table.
  • a disadvantage of the known clamping devices is that either the handling in general and, in particular, the assembly and disassembly are complex or only small forces can be absorbed.
  • the retaining bolt on the top it must be braced on the underside.

  • the clamping device is characterized in that the holding element has a mounting configuration for passing through a hole in the perforated plate and a clamping configuration for bracing with the perforated plate. In this way, the handling of the clamping device is significantly simplified compared to the prior art. With the present solution, forces greater than 10 kN can preferably be absorbed in the longitudinal direction.
  • the holding element preferably has a plurality of holding element parts. Two holding element parts are preferably provided. More preferably, the assembled holding element parts in the clamping configuration form the holding element and/or the holding element in the clamping configuration composed of the holding element parts. Multiple retainer parts allow multiple configurations of the retainer to be set, particularly the mounting configuration and the clamping configuration.

  • the holding element can preferably be adjusted between a plurality of states, in particular between two states, preferably between the mounting configuration and the clamping configuration. More preferably, this is done by pivoting and/or shifting the holding element parts relative to one another. In this way, the configurations can be changed simply by relative displacement of the holding elements.
  • the retaining element in particular together with the retaining bolt, has an overall diameter in the assembly configuration that is smaller than the hole diameter of the perforated plate.

  • the holding element parts are locked to one another in the clamped configuration or are firmly engaged with one another for common load bearing.
  • the forces act in particular as a tensile load, in particular accordingly on the retaining bolt and the retaining elements as well as the counter-retaining element.
  • the retaining element parts are preferably individually designed asymmetrically or eccentrically to the longitudinal axis of the retaining bolt. More preferably, the at least one retaining element part is designed as a projection in the shape of a segment of a circle and/or a semi-circle. These forms offer the possibility of assembling the holding element from a plurality of holding element parts which fit together.
  • the holding element parts are, in particular, eccentric halves.
