Definitions

  • the subject matter of the invention is a mounting pin for an anchoring device according to the preamble of patent claim 1 and a method for extracting mounting pins according to the preamble of patent claim 13.
  • Anchoring devices are used in concrete walls in order to be able to fasten threaded rods, brackets for scaffolding boards and/or railings to the wall after stripping.
  • the anchoring device is attached to the formwork panels before concreting.
  • the mounting pins are initially attached to the formwork by nails and then the anchoring device is pushed onto the pin-shaped plug-in part and anchored to the mounting pin.
  • the mounting pins not only serve to attach the anchoring device to the formwork wall, but they also close the opening cross-section of the anchoring device, ie access for a hook, threaded rod, etc. to the anchoring device against the ingress of concrete, particularly concrete water.
  • the interior of the anchoring device must be accessed by releasing the mounting pin from its engagement with the anchoring device. Since the outer surface of the closure plate lies flush with the surface of the wall that has been constructed, the mounting pin can only be gripped with difficulty if it is not pulled out of the device beforehand when the formwork is removed by the fastening nails on the formwork. In order to be able to pull the mounting pin out of the anchoring device, an additional means is therefore necessary, which enables a tool to engage in the mounting pin.
  • One object of the present invention is to design the mounting pin in such a way that a tool, e.g.
  • the closure plate Due to the formation of at least one film-like area on the closure plate, i.e. one that can be penetrated by a tool, a tool can grip the mounting pin and detach it from the anchoring device.
  • the closure plate is preferably reinforced by a web such as a local thickening of the closure plate. The web preferably extends under the closure panel across the tubular portion of the male member.
  • At least one area from the surface of the closure plate takes the place of a film-like area that can be pierced flap that can be swung out, the root of which is connected to the closure plate in the area of the web below the surface.
  • the tab is delimited on three sides by a predetermined breaking line, which can be broken open by the tool.
  • a tool such as a claw hammer, a reinforcing iron or a screwdriver can reach under the web through the open area and thus pull the mounting pin out of the anchoring device.
  • the mounting pin is held securely by ramp-shaped latching elements arranged on the side of the plug-in part on suitable elevations formed inside the anchoring device while the concrete is being poured into the formwork, i.e. the connection between the mounting pin, which is temporarily attached to the formwork, and the anchoring device can be maintained in this way.
  • Ramped thickenings of the casing of the plug-in part can be formed on the plug-in part of the mounting pin as retaining and locking elements or, in order to facilitate the insertion or plugging of the anchoring device onto the mounting pin after it has been fastened to the formwork, the ramp-shaped locking elements can be made out of the casing be molded out of the plug-in part. These move back a little when the mounting pin is attached and facilitate the plugging and then lock behind the counter-locking means on the anchoring device.
  • reference numeral 1 designates a mounting pin.
  • This comprises a closure plate 3 and an insertion part 5 formed on the bottom thereof.
  • the closure plate 3 and the insertion part 5 can be produced in one piece in an injection molding tool.
  • the two parts 3, 5 are manufactured in one piece, but the connection between the closure plate 3 and the insert part 5 is designed so that it can be broken along a predetermined breaking line 7, i.e. a predetermined breaking area 7, e.g. in the form of a very thin-walled section or Perforations that are not continuous allow the closure plate 3 to be lifted off and separated from the plug-in part 5 after a wall has been created, ie after the formwork has been removed.
  • the plug-in part 5 remains within the in Figure 1a illustrated anchoring device 6, which has been kept closed by the mounting pin 1 during concreting.
  • This predetermined breaking line or this predetermined breaking area 7 is in figure 3 indicated by a broken line. Lines of weakness 7 can be attached to all embodiments of the closure plate 3 .
  • the closure plate 3 are in the first embodiment according to Figures 1b and 1c at least one, preferably two film-like zones or Areas 9 formed.
  • the film-like area or areas 9 are characterized by a very thin wall thickness of, for example, 0.1 mm or 0.2 mm (cf. Figure 1c ).
  • the surrounding areas have a wall thickness several times that of the film-like area 9 .
  • a web 11 is formed on the underside of the closure plate 3, ie on the area protruding into the plug-in part 5, for example by increasing the wall thickness.
  • the web 11 connects the two longer walls 15 which, together with the shorter walls 13, form the rectangular cross-section of the plug-in part 5.
  • the web 11 serves as a force application point when pulling out the mounting pin 1 from the opening 7 of the anchoring device 6.
  • one or both film-like areas 9 are broken through with a tool, for example a claw hammer, a reinforcing iron or a screwdriver 31 and the web 11 is grasped so that a vertically extending pull-out force can occur on the mounting pin 1.
  • a tool for example a claw hammer, a reinforcing iron or a screwdriver 31 and the web 11 is grasped so that a vertically extending pull-out force can occur on the mounting pin 1.
  • a tool for example a claw hammer, a reinforcing iron or a screwdriver 31 and the web 11 is grasped so that a vertically extending pull-out force can occur on the mounting pin 1.
  • a tool for example a claw hammer, a reinforcing iron or a screwdriver 31
  • the web 11 is grasped so that a vertically extending pull-out force can occur on the mounting pin 1.
  • a mounting pin with a different cross section for example circular or oval
  • Such a mounting pin for example circular, is inserted into an anchoring device with a correspondingly circular cross-section or a circular opening provided for the insertion part (no illustrations).
  • latching elements 17 are placed or formed on the surface of the long wall 15 on the plug-in part 5 or protrude from the wall 15 as hollow bulges. They can also be formed as indentations in the long wall of the plug-in part 5 (not shown) if inwardly directed ribs are formed on the anchoring device, which snap into place after the mounting pin 1 has been inserted into the anchoring device.
  • the tabs 21 are torn open or unfolded using a tool, such as a claw hammer, a reinforcing iron or a screwdriver 31, and through the resulting opening 23 in the closure plate 3 it is possible to guide the tool 31 either under the central web 11 and by pivoting it into Pull out the closure plate 3 together with the plug-in part 5 from the anchoring device 6 in the direction of the arrow P or, if a predetermined breaking line 7 is provided, just detach the closure plate 3 from the plug-in part 5 .
  • the tab 21 can be broken through from the underside by a lattice hammer, screwdriver or the like, and then the mounting pin 1 can be grasped and pulled out.
  • a first embodiment of the mounting pin relates to a mounting pin 1 for an anchoring device 6 for closing its insertion opening, which is used for inserting a hook or threaded rod and for temporarily fastening the anchoring device 6 with the mounting pin 1 on a formwork panel, comprising a closure panel 3 with a tubular insert 5 on the closure plate 3, wherein the Closure plate 3 protrudes outwards over the side walls 13, 15 of the plug-in part 5 in the manner of a flange, with ramp-shaped latching elements 17 leading away from the surface of the outer wall 15 being formed on the outer wall 15 of the plug-in part 5.
