Backup wall reinforcement with t-type siderail

Abstract

A backup wall reinforcement with T-type siderail anchoring system is described for use in masonry cavity walls. The reinforcement and integral anchor is hybrid device installed within the backup wall and interlocked with novel veneer ties. The novel veneer ties are manually connected through swinging or twisting the veneer ties until the veneer ties are interlocked with the anchor. Once interlocked, lateral and vertical veneer tie movement is limited strengthening the cavity wall structure. The inclusion of a reinforcement wire within the veneer ties and the exterior wall provides a seismic structure.

         5 . An anchoring system as described in  claim 4 , wherein said anchoring system further comprises:
 a reinforcement wire, said reinforcement wire for insertion within said one or more reinforcement notches,   whereby, upon installation a seismic construct is formed.   
     
     
         6 . An anchoring system as described in  claim 4 , wherein said insertion portion is offset from said cavity portion, said insertion portion configured upon installation to secure said cavity portion against said interior of said facing wall. 
     
     
         7 . An anchoring system as described in  claim 2 , wherein said veneer tie is stamped metal. 
     
     
         8 . An anchoring system for use in a cavity wall having a backup wall and a facing wall in a spaced apart relationship having a cavity therebetween, said backup wall and said facing wall each having an interior side facing said cavity, said backup wall and said facing wall each formed from successive courses of masonry block each with a bed joint of predetermined height between each two adjacent courses and, further, each course of masonry block having an embedment surface lying in a substantially horizontal plane, said anchoring system comprising:
 a wall reinforcement portion adapted for disposition upon one of said courses of masonry blocks for embedment in said bed joint of said backup wall, said wall reinforcement, further, comprising;
 a pair of side wires with the longitudinal axes thereof disposed parallel to one another, said pair of side wires having interior surfaces disposed opposite each other; 
 one or more intermediate wires each having a longitudinal axis, said one or more intermediate wires attached to said interior surfaces of said side wires maintaining the parallelism thereof and having the axes of said side wires and said intermediate wires being substantially coplanar; 
   at least one wall anchor portion formed from one of said side wires configured to extend into said cavity, said wall anchor portion further comprising, in turn,
 t-type wire formatives extending into said cavity, said t-type wire formatives forming a buckle and a throat dimensioned to engage a veneer tie. 
   
     
     
         9 . An anchoring system as described in  claim 8 , wherein said anchoring system further comprises a veneer tie, said veneer tie, in turn comprising:
 a strap, said strap dimensioned to interlock with said wall anchor portion, said strap having a slot, said slot dimensioned to be inserted over said buckle and said throat; and   a free end portion continuous with said strap,   whereby upon emplacement and rotation of said strap on said wall anchor portion, said veneer tie is securely interlocked with said wall anchor portion.   
     
     
         10 . An anchoring system as described in  claim 9 , wherein said slot is dimensioned upon installation to restrain lateral and vertical movement. 
     
     
         11 . An anchoring system as described in  claim 9 , wherein said free end portion further comprises
 a cavity portion, said cavity portion configured to span said cavity;   an insertion portion, said insertion portion continuous with said cavity portion and dimensioned for disposition within said bed joint of said facing wall; and   one or more reinforcement notches, said one or more reinforcement notches disposed in said insertion portion and dimensioned to receive a reinforcement wire.   
     
     
         12 . An anchoring system as described in  claim 11 , wherein said anchoring system further comprises:
 a reinforcement wire, said reinforcement wire for insertion within said one or more reinforcement notches,   whereby upon installation a seismic construct is formed.
