Tie bar assembly

Abstract

A tie bar assembly including a tie bar sleeve, a tie bar insert insertable to the tie bar sleeve, and a tie bar insertable to the tie bar insert. During construction, the tie bar is insertable into and secured in the tie bar insert. The tie bar and the tie bar insert are then insertable into and secured in the tie bar sleeve. This assembly is fastened to the form. After the first slab is poured the first tie bar and the tie bar sleeve are embedded in the first slab. The form is removed, and the second slab is then poured and encapsulates at least a portion of the remainder of the tie bar sleeve, tie bar insert, and tie bar.

The claims are as follows: 
     
         1 . A tie bar assembly for a first concrete slab and a second concrete slab, the tie bar assembly comprising:
 a tie bar sleeve; and   a tie bar insert insertable in the tie bar sleeve, the tie bar insert configured to receive a tie bar,
 wherein a portion of the tie bar sleeve, the tie bar insert, and the tie bar are configured to be positioned in the first concrete slab, and 
 wherein at least a portion of a remainder of the tie bar sleeve, the tie bar insert, and the tie bar are configured to be positioned in the second concrete slab. 
   
     
     
         2 . The tie bar assembly of  claim 1 , wherein the tie bar sleeve includes a receiver configured to receive the tie bar insert. 
     
     
         3 . The tie bar assembly of  claim 2 , wherein the receiver incudes a front boss and a rear boss. 
     
     
         4 . The tie bar assembly of  claim 3 , wherein the receiver defines a tie bar insert receiving opening. 
     
     
         5 . The tie bar assembly of  claim 4 , wherein the tie bar sleeve is configured to secure the tie bar insert within the tie bar receiving opening. 
     
     
         6 . The tie bar assembly of  claim 5 , wherein the tie bar insert defines a tie bar receiving opening. 
     
     
         7 . The tie bar assembly of  claim 6 , wherein the tie bar insert is configured to secure the tie bar within the tie bar receiving opening. 
     
     
         8 . The tie bar assembly of  claim 7 , wherein the tie bar sleeve includes inwardly extending ribs configured to secure the tie bar insert within the tie bar insert receiving opening. 
     
     
         9 . The tie bar assembly of  claim 8 , wherein the tie bar insert includes inwardly extending ribs configured to secure the tie bar within the tie bar receiving opening. 
     
     
         10 . The tie bar assembly of  claim 1 , which includes the tie bar. 
     
     
         11 . A tie bar assembly for a first concrete slab and a second concrete slab, the tie bar assembly comprising:
 a tie bar sleeve including:
 an attaching wall configured to be attached to a concrete form; and 
 a receiver configured to receive a tie bar insert insertable into the tie bar sleeve. 
   
     
     
         12 . The tie bar assembly of  claim 11 , wherein the receiver incudes a front boss and a rear boss. 
     
     
         13 . The tie bar assembly of  claim 12 , wherein the receiver defines a tie bar insert receiving opening. 
     
     
         14 . The tie bar assembly of  claim 13 , which is configured to secure the tie bar insert within the tie bar insert receiving opening. 
     
     
         15 . The tie bar assembly of  claim 14 , which includes inwardly extending ribs configured to secure the tie bar insert within the tie bar insert receiving opening. 
     
     
         16 . The tie bar assembly of  claim 11 , wherein the attaching wall includes a locator configured to locate the tie bar sleeve relative to a hole in the concrete form. 
     
     
         17 . A tie bar assembly for a first concrete slab and a second concrete slab, the tie bar assembly comprising
 a tie bar sleeve; and   a tie bar insert insertable in the tie bar sleeve, the tie bar insert including:
 a top wall; 
 a first side wall; 
 a bottom wall; and 
 a second side wall, 
 wherein the top wall, the first side wall, the bottom wall, and the second side wall are insertable into and securable within a receiver of the tie bar sleeve. 
   
     
     
         18 . The tie bar assembly of  claim 17 , wherein the insert defines a tie bar receiving opening. 
     
     
         19 . The tie bar assembly of  claim 18 , where the insert is configured to secure the tie bar within the tie bar receiving opening. 
     
     
         20 . The tie bar assembly of  claim 19 , wherein the insert includes inwardly extending ribs configured to secure the tie bar within the tie bar receiving opening.
