Definitions

  • a through hole cleaning method with a hollow drill is known in which air is blown through the hollow drill into the borehole during the drilling of the borehole. Accumulating drill cuttings and drill dust are thereby blown out of the borehole, which can pollute the environment of the borehole.
  • the desired tensile loads in the range of more than 1000 Newtons are transferred from the self-hardening mortar only to the component when the drill dust is removed cleanly.
  • smooth borehole walls made by sawing or grinding tend to be very easy to clean by suction, but still do not allow sufficient adhesion of the mortar to the boring wall.
  • a partially chiselling tool, the beating hollow drill probably leads to sufficient roughness and cracks in the borehole wall, so that the mortar sticks.
  • the self-hardening mortar is introduced as two components in the borehole.
  • the self-hardening mortar may be based on an epoxy resin and / or and / or polymethacrylate.
  • the fastener anchored in the self-hardening mortar is designed for tensile loads of at least 1000 Newton
  • the hollow drill 12 comprises a shaft 16 having at a first, front end a drill head 13 with outlet openings 14 and at the other, rear end a spigot 15 for mounting the hollow drill 12 in a tool holder 8 of a not shown beating and rotating drill.
  • a radially outwardly open inlet opening 17 is provided, which is connected via a circumferentially closed, provided in the shaft 16 longitudinal channel 18 with the outlet openings 14 on the drill head 13 in connection.
  • the suction hood 21 is bell-shaped and has a passage opening 22 for the hollow drill 12 and a connecting piece 23 for connecting a suction line 27 as a connection to the vacuum source 26.
  • the passage opening 22 may with a sealing device, such as. B. radially inwardly projecting brush elements or flexible sealing elements, for partial sealing of the passage opening 22 may be provided.
