Abstract

An anchor for supporting a load comprises an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for extending outside the concrete structure; a metallic body attached to the lower portion, the body including a top surface and a bottom surface joined by a vertical side surface; and the side surface including at least one shoulder extending therefrom.

Claims

exact text as granted — not AI-modified
I claim: 
     
         1 - 13 . (canceled) 
     
     
         14 . An anchor for supporting a load, comprising:
 a) an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for attachment to a load;   b) a metallic wedge-shaped body attached to said lower threaded portion; and   c) said body is circular in cross-section and including a circular top surface and a circular bottom surface joined by a side surface.   
     
     
         15 . An anchor as in  claim 14 , wherein said side surface is conical. 
     
     
         16 . An anchor as in  claim 14 , wherein said side surface is convex. 
     
     
         17 . An anchor as in  claim 14 , wherein said body includes a shoulder extending from said surface. 
     
     
         18 . An anchor as in  claim 17 , wherein said surface terminated into said shoulder with a radius surface. 
     
     
         19 . An anchor as in  claim 14 , wherein said body includes a central opening. 
     
     
         20 . An anchor as in  claim 19 , wherein said opening is threaded. 
     
     
         21 . An anchor for supporting a load, comprising:
 a) an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for attachment to a load;   b) a metallic cylindrical body attached to said lower threaded portion; and   c) said body including an upper horizontal edge surface to provide a load bearing surface, said body including a bottom surface joined to said upper horizontal edge surface by a side surface.   
     
     
         22 . An anchor as in  claim 21 , wherein said body includes outside threads. 
     
     
         23 . An anchor as in  claim 21 , wherein said body includes a shoulder extending from said side surface. 
     
     
         24 . An anchor as in  claim 21 , wherein:
 a) said body includes a circumferential groove disposed at a bottom end portion; and   b) a split ring disposed within said groove.   
     
     
         25 . An anchor as in  claim 21 , wherein said body includes a central opening. 
     
     
         26 . An anchor as in  claim 25 , wherein said opening is threaded. 
     
     
         27 . An anchor for supporting a load, comprising:
 a) an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for attachment to a load;   b) a metallic body attached to said lower threaded portion, said body including first cylindrical portion disposed next to a second cylindrical portion; and   c) said first cylindrical portion including a circumferential portion extending beyond said second cylindrical portion.   
     
     
         28 . An anchor as in  claim 27 , wherein said body includes a central opening. 
     
     
         29 . An anchor as in  claim 28 , wherein said opening is threaded.
