Concrete Anchor Insertion Device and Method

Abstract

A device for mounting anchors having a mounting end for positioning within pre-drilled apertures formed in concrete or cement and having a threaded end projecting forward of the pre-drilled apertures when positioned therein. The device features a continues shaft that is adapted to engage with a hammer drill on a first end, and the threaded portion of the anchor on the opposite end to allow the hammer drill to force the anchor into its aperture in the concrete. A nut for the threaded portion is rotatable for engagement by a second component coaxially engaged with the shaft. The device allows for both hammering the anchor into its aperture and tightening the nut, without removing the device from its engagement with the anchor.

1 . An apparatus for mounting anchors having a mounting end for positioning within pre-drilled apertures formed in concrete or cement, and having a threaded end projecting forward of said pred-formed apertures, comprising:
 an shaft, said shaft having a proximal end and a distal end opposite said proximal end, and a central portion therebetween;   said proximal end adapted for engagement with the chuck of a hammer drill;   said distal end having an axial cavity;   said axial cavity adapted to engage around said threaded end of said anchors;   a second member having an axial passage running therethrough, said second member having a first end and a second end opposite said engagement end;   said second member coaxially engaged with said shaft communicating within said axial passage;   said first end of said second member connected to a mount at said central portion of said shaft;   said second end having an engagement cavity therein, said engagement cavity adapted to engage with a nut which is adapted for threaded engagement upon said threaded end of said anchor; and   said threaded end of said mounting anchor engageable within said axial cavity by communicating through said engagement cavity, whereby said mounting anchor may be hammered into said pre-drilled apertures by a hammering force of said hammer drill engaged to said shaft and said nut may be subsequently turned onto said threaded end by a rotation of said shaft communicated thereto by rotational force of said hammer drill while said engagement end connected upon said nut.   
   
   
       2 . The apparatus for mounting anchors of  claim 1  additionally comprising:
 said mount being a clutch;   said clutch configured to cause slippage of said rotation of said shaft should said rotational force exceed a pre-set maximum; and   said hammering force being unaffected by said slippage of said clutch, whereby said hammering force is directly communicated to said mounting anchor and said rotational force is always communicated through said clutch at or below said pre-set maximum.   
   
   
       3 . The apparatus for mounting anchors of  claim 1  additionally comprising:
 said first end of said second member being in a removable engagement with said mount whereby said second member may be removed from said shaft.   
   
   
       4 . The apparatus for mounting anchors of  claim 3  additionally comprising:
 said first end of said second member being in a removable engagement with a side surface of said clutch, whereby said second member may be removed from said shaft.   
   
   
       5 . The apparatus for mounting anchors of  claim 3  additionally comprising:
 said axial cavity being threaded to threadably engage with said threaded end of said anchors.   
   
   
       6 . The apparatus for mounting anchors of  claim 4  additionally comprising:
 said axial cavity being threaded to threadably engage with said threaded end of said anchors.   
   
   
       7 . The apparatus for mounting anchors of  claim 2  additionally comprising:
 said clutch being adjustable to thereby provide means for adjustment of said pre-set maximum.   
   
   
       8 . The apparatus for mounting anchors of  claim 3  additionally comprising:
 said clutch being adjustable to thereby provide means for adjustment of said pre-set maximum.   
   
   
       9 . The apparatus for mounting anchors of  claim 4  additionally comprising:
 said clutch being adjustable to thereby provide means for adjustment of said pre-set maximum.   
   
   
       10 . The apparatus for mounting anchors of  claim 5  additionally comprising:
 said clutch being adjustable to thereby provide means for adjustment of said pre-set maximum.   
   
   
       11 . The apparatus for mounting anchors of  claim 6  additionally comprising:
 said clutch being adjustable to thereby provide means for adjustment of said pre-set maximum.
