Side mounted drill bolt and threaded anchor system for veneer wall tie connection

Abstract

In accordance with one aspect of the present invention, a load transfer system includes a back-up wall and at least one panel disposed adjacent the back-up wall. A veneer wall is spaced from the back-up wall. A drill bolt having a generally cylindrical shaft extending between first and second ends is provided. A portion of the shaft adjacent the first end is secured to the back-up wall and a portion of the shaft adjacent the second end extends through a penetration hole in the at least one panel. A clip is disposed on the second end of the drill bolt within the space between the back-up wall and the veneer wall. A wire tie extends between the clip and the veneer wall.

         2 . The load transfer system of  claim 1 , wherein the at least one panel comprises one or more of wall sheeting and insulation board. 
     
     
         3 . The load transfer system of  claim 1 , wherein the second end of the drill bolt shaft includes a threaded portion, and wherein the clip includes a complementary threaded portion that is adapted to be threaded onto the second end of the drill bolt shaft. 
     
     
         4 . The load transfer system of  claim 1 , wherein the second end of the drill bolt shaft includes a threaded bore adapted to alternatively receive one of a drill tip with a complementary threaded member and a clip with a complementary threaded projection. 
     
     
         5 . The load transfer system of  claim 1 , wherein the clip is adapted to be independently rotatable in two directions relative to the drill bolt so that the clip may be angularly adjusted and longitudinally spaced from a surface of the back up wall by a distance of about L measured parallel to a longitudinal axis of the drill bolt shaft. 
     
     
         6 . The load transfer system of  claim 5 , wherein the distance L is about equal to a width of the at least one panel. 
     
     
         7 . The load transfer system of  claim 5 , wherein the wire tie is vertically adjustable within an opening of the clip. 
     
     
         8 . The load transfer system of  claim 1 , wherein a plurality of fasteners affix the portion of the shaft adjacent the first end to the back-up wall. 
     
     
         9 . The load transfer system of  claim 1 , wherein the penetration hole in the at least one panel is substantially equal in size to a diameter of the drill bolt shaft. 
     
     
         10 . The load transfer system of  claim 1 , wherein the portion of the shaft adjacent the first end is secured to a web surface of the back-up wall, and wherein a plane coincident therewith is substantially parallel to a longitudinal axis of the drill bolt shaft. 
     
     
         11 . The load transfer system of  claim 1 , wherein the clip comprises at least one of a U-clip, a slot nut, an L-clip, a wing-nut clip, a U-rail, and a rod-rail. 
     
     
         12 . The load transfer system of  claim 1 , wherein the portion of the shaft that extends through the penetration hole in the at least one panel includes at least one of a hole extending through the shaft and a smaller cross-sectional diameter about a longitudinal axis of the shaft in relation to the portion of the shaft adjacent the first end. 
     
     
         13 . The load transfer system of  claim 1 , wherein the second end of the shaft is provided with a threaded recess having a first end of a threaded core received therein, and wherein a second end of the threaded core is received within a threaded cavity of a drilling head. 
     
     
         14 . The load transfer system of  claim 13 , wherein the drilling head is comprised of a plastic. 
     
     
         15 . The load transfer system of  claim 13 , wherein a plastic sleeve is provided over the threaded core between the second end of the shaft and the drilling head. 
     
     
         16 . The load transfer system of  claim 15 , wherein one or more of the shaft, the threaded core, the drilling head, and the sleeve are separable from one another. 
     
     
         17 . A load transfer system, comprising:
 a back-up wall and at least one panel disposed adjacent the back-up wall;   a veneer wall spaced from the back-up wall;   means for securing a drill bolt to the back-up wall; and   means for securing the drill bolt to a wire tie attached to the veneer wall.   
     
     
         18 . A method of transferring a horizontal load between a back-up wall and a veneer wall, the method comprising the steps of:
 providing a veneer wall spaced from a back-up wall;   driving a drill bolt with first and second ends through at least one panel disposed adjacent the back-up wall, wherein a portion of the second end is threaded and is disposed within the space between the back-up wall and the veneer wall;   securing the portion of the drill bolt adjacent the first end to the back-up wall;   threadably attaching a clip to the second end of the drill bolt, wherein the clip includes at least one opening to receive a wire tie; and   inserting a wire tie into the at least one opening in the clip, wherein the wire tie is further attached to portions of the veneer wall.   
     
     
         19 . The method of  claim 18 , further including the step of rotating the clip in one of two directions relative to the drill bolt so that the clip may be angularly adjusted and longitudinally spaced from a surface of the back-up wall by a distance of about L measured parallel to a longitudinal axis of the drill bolt and vertically adjusting the wire tie within the at least one opening of the clip. 
     
     
         20 . The method of  claim 18 , wherein driving the drill bolt through the at least one panel creates a hole therein, which is substantially equal in size to a diameter of the drill bolt.
