Definitions

  • the subject of the invention is a mounting pin for an anchoring device according to the preamble of patent claim 1 and a method for pulling out mounting pins according to the preamble of claim 13.
  • Anchoring devices are used in concrete walls in order to be able to attach 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 insert and anchored to the mounting pin.
  • the mounting pins are not only used to attach the anchoring device to the formwork wall, but they 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, especially concrete water.
  • the assembly pin can only be grasped poorly if it is not pulled out of the device by the fastening nails on the formwork during stripping.
  • an additional means is consequently necessary which enables a tool to engage on the mounting pin.
  • formwork panels made of metal because with such the assembly pin cannot be connected to the formwork panel in such a way that it adheres to the formwork panel during stripping and is consequently not pulled out of the anchoring device.
  • a tool e.g. a claw hammer, a reinforcing iron or a screwdriver finds a support on the locking plate in order to be able to pull it out against the resistance of the latching.
  • the closure plate is preferably reinforced by a web such as a local thickening of the closure plate.
  • the web preferably extends below the closure plate across the tubular area of the plug-in part.
  • at least one area from the surface of the closure plate replaces a pierceable film-like area Swing-out flap, 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 roofing hammer, a reinforcing iron or a screwdriver can reach under the web through the open area and thus pull the assembly pin out of the anchoring device.
  • Ramp-shaped locking elements arranged on the side of the plug-in part securely hold the mounting pin 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 sustained in this way.
  • Ramp-shaped thickenings of the shell of the insert part can be designed as retaining and locking elements on the insertion part of the mounting pin or, in order to facilitate the insertion or attachment of the anchoring device to the mounting pin after it has been attached to the formwork, the ramp-shaped locking elements can be removed from the shell of the plug-in part. These move back a little when the mounting pin is put on and make it easier to put on and then lock behind the counter-locking means on the anchoring device.
  • reference numeral 1 denotes a mounting pin.
  • This comprises a closure plate 3 and an insert part 5 molded onto it at the bottom.
  • the closure plate 3 and the insert part 5 can be produced in one piece in an injection molding tool.
  • the two parts 3, 5 are made in one piece, but the connection between the closure plate 3 and the plug-in part 5 is designed to be breakable along a predetermined breaking line 7, that is to say a predetermined breaking area 7, for example in the form of a very thin-walled section or non-continuous perforations enable 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 insertion part 5 remains within the in Figure 1a shown 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.
  • Predetermined breaking lines 7 can be applied in 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 that is a multiple of the film-like area 9.
  • a web 11 for example by increasing the wall thickness, is formed on the closure plate 3 on its underside, ie on the area protruding into the insert part 5.
  • 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 introduction point when pulling the mounting pin 1 out of the opening 7 of the anchoring device 6.
  • a tool for example a claw hammer, a reinforcing iron or a screwdriver 31 and the web 11 is gripped under so that a vertical pull-out force can be applied to the mounting pin 1.
  • a mounting pin 1 can also be provided with a different, for example circular or oval cross-section with the features described above.
  • a mounting pin is inserted into an anchoring device with a correspondingly round cross section or a circular opening provided for the plug-in part (no figures).
  • latching elements 17 are placed or molded onto 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 designed as indentations in the long wall of the plug-in part 5 (not shown) if the anchoring device has inwardly directed ribs which snap into place after the mounting pin 1 has been inserted into the anchoring device. Similar to the structure of the latching elements 17 on the walls 15 of the plug-in part 5, the closure plate 3 is in the second embodiment Figures 2a to 2d educated.
  • a tab 21 is created in each case, which, broken open as in FIG Figure 2c shown, can be opened upwards.
  • the flaps 21 are torn open or unfolded by the tool, such as a claw hammer, a reinforcing iron or a screwdriver 31 and, through the opening 23 in the closure plate 3, enables the tool 31 to be guided either under the central web 11 and pivoted in In the direction of arrow P, to pull the closure plate 3 together with the plug-in part 5 out of the anchoring device 6 or, if a predetermined breaking line 7 is provided, only to detach the closure plate 3 from the plug-in part 5.
  • the tab 21 can be pierced from the underside by a claw hammer, screwdriver or the like, and the assembly pin 1 can then be grasped and pulled out.
