Rebar attachment device and system

Abstract

A rebar attachment device includes a vertical attachment device having a base member that includes a bottom surface for making contact with a piling, and a top surface for positioning a sleeve and a pair of flexible chairs. Each of the chairs acts to removably engage and position a rebar rod at a predetermined separation distance from the base member. A rebar attachment system includes at least one vertical rebar attachment device, at least one horizontal rebar attachment device, a tether for positioning the at least one vertical device onto a piling, and a tether connector for securing the tether to the piling.

1 . A vertical rebar attachment device for securing rebar rods to a piling, said device comprising:
 a base member having a bottom surface configured to make contact with a piling, and a top surface;   a sleeve secured to the base member, said sleeve including a pair of diametrically opposed openings and a hollow interior portion forming a channel for receiving a tether; and   a pair of flexible chairs secured to the top surface of the base member, each of said chairs being configured to removably engage and position a rebar rod in a vertical orientation and at a predetermined separation distance from the base member.   
     
     
         2 . The device of  claim 1 , wherein each of said chairs comprises:
 a pair of curved retention shafts having a first end secured to the base member, and a second end protruding outward from the base member,   each of said shafts having a complementary shape forming a semicircular area for engaging the rebar rod.   
     
     
         3 . The device of  claim 2 , wherein the semicircular area is configured to engage rebar rods of varying dimensions. 
     
     
         4 . The device of  claim 1 , wherein said predetermined distance is one inch. 
     
     
         5 . The device of  claim 1 , further comprising:
 a plurality of openings extending from the top surface of the base member to the bottom surface of the base member, each of said openings being configured to receive a concrete anchor.   
     
     
         6 . The device of  claim 1 , wherein the bottom surface of the base member includes a curved portion, said curved portion being configured to allow the device to be positioned onto pilings with curved surfaces. 
     
     
         7 . The device of  claim 6 , wherein said curved surface includes a ninety degree bend configured to allow the device to be secured to a corner section of a piling. 
     
     
         8 . The device of  claim 1 , wherein each of said base member, sleeve and chairs are constructed from a single mold of injected plastic. 
     
     
         9 . A horizontal rebar attachment device for securing rebar rods to a piling, said device comprising:
 a base member having a bottom surface and a top surface;   a pair of vertical chairs secured to the top surface of the base member, each of said chairs being configured to removably engage a pre-installed vertical rod; and   a horizontal chair configured to removably engage and position another rebar rod in a horizontal orientation.   
     
     
         10 . (canceled) 
     
     
         10 . A rebar attachment system for securing rebar rods to a piling, said system comprising:
 an elongated tether having a first end, a second end, and a length greater than an outside dimension of the pile;   a tether connector configured to secure the first and second ends of the tether together around the pile;   a plurality of vertical rebar attachment devices, each of said devices including
 a base member having a bottom surface configured to make contact with the piling, and a top surface, 
 a sleeve having a pair of diametrically opposed openings and a hollow interior portion forming a channel configured to receive the tether, and 
 a pair of flexible chairs secured to the top surface of the base member, each of said chairs being configured to removably engage and position a rebar rod at a predetermined separation distance from the base member, 
   wherein said tether is further configured to securely position the at least one attachment device to the piling; and   a plurality of horizontal rebar attachment devices, each of said devices including
 a base member having a bottom surface and a top surface, 
 a pair of vertical chairs secured to the top surface, each vertical chair of the horizontal rebar attachment device being configured to removably engage a pre-installed vertical rod, and 
 a horizontal chair configured to removably engage and position another rebar rod in a horizontal orientation. 
   
     
     
         11 . The system of  claim 10 , wherein each chair of both the vertical and horizontal rebar attachment devices are configured to engage rebar rods of varying dimensions. 
     
     
         12 . The system of  claim 10 , wherein said predetermined distance is one inch. 
     
     
         13 . The system of  claim 10 , wherein at least one of said vertical rebar attachment devices includes a curved bottom surface configured to be positioned onto pilings with curved surfaces. 
     
     
         14 . The system of  claim 13 , wherein said curved surface includes a ninety degree bend configured to allow the device to be secured to a corner section of a piling. 
     
     
         15 . The system of  claim 10 , wherein said tether includes a polyester pallet band having a breaking strength of at least 1500 psi, and configured to be cut to a length approximating the outside dimension of the piling. 
     
     
         16 .- 20 . (canceled) 
     
     
         21 . The device of  claim 9 , wherein each of the vertical and horizontal chairs are configured to engage rebar rods of varying dimensions.
