Definitions

  • the invention relates to a prop holder of a construction prop with three legs and with at least one building support system for the building support and a holding means for Holding the building support at the building support system.
  • Such a column holder has become known, for example, from EP 0 065 156 B1 .
  • the closure part holds the support shaft in the receptacle, one of the parts of the support shaft at most so far that there is a space between its edges, which corresponds at least to the column diameter.
  • the second part is as a slider formed and is guided by a wedge surface acting with respect to the first part.
  • the contact surface of at least one of the parts on the support shaft runs in Essentially in a plane parallel to the column axis and has one in cross section V-shaped centering channel perpendicular to the column axis.
  • the object of the present invention is the support holder mentioned at the outset to further develop that a safer movement on a construction site is possible, even if several prop holders are in close proximity to each other are set up.
  • a first fixing device is in particular a first fixing plate is provided, which the legs in the area of their spreading point fixed in their position to each other. Because the spreading takes place near the ground , the first fixing device is preferably also arranged near the floor. This measure increases the stability of the support bracket. It is conceivable to attach the legs with an end section to a fixation plate, which in small Distance to the floor is arranged. Below or at the level of the fixing plate the legs then spread out sideways so that the support is well supported or the support is achieved and the legs are arranged near the floor.
  • the prop holder can be configured for different purposes.
  • One leg is preferably on the support holder, in particular on the first fixing device, non-rotatably arranged. This measure allows a quick installation of the column holder without impairing its flexibility.
  • the legs have a vertical section and an angled foot section.
  • the foot section is preferred arranged below the first fixing device and represents the part of the Leg that spreads sideways and for the stability of the support bracket provides.
  • the vertical sections of the legs are in their Position relative to one another by the first fixing device and a second fixing device, in particular a second fixing plate. Because the legs on two Make a fixed distance from each other, the stability of the Column holder increased.

  • the legs above the second fixation device against slipping out Secure legs from the first and second fixation devices. This will make it of the column holder simplified, since the individual legs do not match the first or second fixing device must be connected.
  • a slipping out of the Legs in the opposite direction is due to the angling of the foot sections compared to the vertical sections. The foot sections are therefore from below against the first fixing device.
  • the spacer has at its free ends each have at least one projection, which is assigned by at least one Recess of the first or second fixing device protrudes and an edge of the Recess is permanently deformed, each of which moves the fixing device along the spacer preventing counter bearing is provided.
  • the connection by permanent deformation has the advantage that the spacer does not have to be connected to the fixing devices by welding.
  • Provided surface-coated material is used for the manufacture of the column holder surface finish of the spacer before welding and the fixing devices for the welding are removed so the quality or the strength of the weld is guaranteed. After welding together would usually have to be reworked and protected against corrosion become. These steps are not necessary if the spacer and the fixing devices are connected by permanent deformation.
