Stud rail with adjustable stud mounting

Abstract

A reinforcing stud for a stud rail includes an elongated stud body defining a first diameter. A first load transfer head is disposed at one longitudinal end of the elongated stud body. A second load transfer head is disposed at the other longitudinal end of the elongated stud body. The second load transfer head includes spaced apart mounting flanges on an end surface thereof. The mounting flanges define a channel for receiving a rail. At least one of the mounting flanges has a threaded opening through a wall thereof for receiving a set screw.

What is claimed is: 
     
         1 . A reinforcing stud for a stud rail, comprising:
 an elongated stud body defining a first diameter;   a first load transfer head disposed at one longitudinal end of the elongated stud body; and   a second load transfer head disposed at the other longitudinal end of the elongated stud body, the second load transfer head comprising spaced apart mounting flanges on an end surface thereof, the mounting flanges defining a channel for receiving a rail therein, at least one of the mounting flanges having a threaded opening through a wall thereof for receiving a set screw.   
     
     
         2 . The reinforcing stud of  claim 1  wherein the mounting flanges define a substantially rectangular cross-section. 
     
     
         3 . The reinforcing stud of  claim 1  wherein an interior wall of at least one mounting flange is substantially perpendicular to the end surface of the second load transfer head. 
     
     
         4 . The reinforcing stud of  claim 1  wherein at least one of the first load transfer head and the second load transfer head defines a second diameter greater than the first diameter. 
     
     
         5 . The reinforcing stud of  claim 4  wherein the at least one of the first load transfer head and the second load transfer head comprises a transition between the first diameter and the second diameter. 
     
     
         6 . The reinforcing stud of  claim 5  wherein a length of the transition is at least one half a diameter of the stud body. 
     
     
         7 . The reinforcing stud of  claim 1  wherein both mounting flanges comprise a threaded opening through the wall thereof for receiving a set screw. 
     
     
         8 . The reinforcing stud of  claim 1  wherein the set screw comprises a socket head screw. 
     
     
         9 . A stud rail for reinforcing a concrete structure, comprising:
 a longitudinally extending rail; and   a plurality of reinforcing studs mounted to the rail at selected locations along the longitudinally extending rail, each of the plurality of reinforcing studs comprising an elongated stud body defining a first diameter, a first load transfer head disposed at one longitudinal end of the elongated stud body, and a second load transfer head disposed at the other longitudinal end of the elongated stud body, the second load transfer head comprising spaced apart mounting flanges on an end surface thereof, the mounting flanges defining a channel for receiving a rail therein, at least one of the mounting flanges having a threaded opening through a wall thereof for receiving a set screw.   
     
     
         10 . The stud rail of  claim 9  wherein the mounting flanges define a substantially rectangular cross-section. 
     
     
         11 . The stud rail of  claim 9  wherein an interior wall of at least one mounting flange is substantially perpendicular to the end surface of the second load transfer head. 
     
     
         12 . The stud rail of  claim 9  wherein at least one of the first load transfer head and the second load transfer head defines a second diameter greater than the first diameter. 
     
     
         13 . The stud rail of  claim 9  wherein the at least one of the first load transfer head and the second load transfer head comprises a transition between the first diameter and the second diameter. 
     
     
         14 . The reinforcing stud of  claim 13  wherein a length of the transition is at least one half a diameter of the stud body. 
     
     
         15 . The stud rail of  claim 9  wherein both mounting flanges comprise a threaded opening through the wall thereof for receiving a set screw. 
     
     
         16 . The stud rail of  claim 9  wherein the set screw comprises a socket head screw. 
     
     
         17 . The stud rail of  claim 9  wherein the longitudinally extending rail defines a substantially rectangular cross-section. 
     
     
         18 . The stud rail of  claim 9  wherein the spaced apart locations are equally spaced.
