Load-Transfer Device For Reinforcing Concrete Structures

Abstract

A load-transfer device for a structure comprises a top member, a bottom member and at least one web member. The top member comprises a bottom surface adapted to receive a top surface of the structure. The bottom member comprises a top surface adapted to receive a bottom surface of the structure. Each web member comprises at least one aperture extending through the web member between the bottom surface of the top member and the top surface of the bottom member. Each aperture is capable of receiving a bolt member that is capable of fastening at least one of the top member, the bottom member or combinations thereof to the web member.

1 . A load-transfer device for a structure, comprising
 a top member comprising a bottom surface adapted to receive a top surface of the structure;   a bottom member comprising a top surface adapted to receive a bottom surface of the structure; and   at least one web member disposed between the bottom surface of the top member and the top surface of the bottom member, each web member comprising at least one aperture extending through the web member between the bottom surface of the top member and the top surface of the bottom member, each aperture capable of receiving a bolt member that is capable of fastening at least one of the top member, the bottom member or combinations thereof to the web member.   
   
   
       2 . The load-transfer device according to  claim 1 , wherein at least one web member is welded to the top member. 
   
   
       3 . The load-transfer device according to  claim 1 , wherein at least one web member is integrally forged with the top member. 
   
   
       4 . The load-transfer device according to  claim 1 , wherein at least one web member is welded to the bottom member. 
   
   
       5 . The load-transfer device according to  claim 1 , wherein at least one web member is integrally forged with the bottom member. 
   
   
       6 . The load-transfer device according to  claim 1 , wherein the top member, the bottom member and the web member are formed from stainless steel. 
   
   
       7 . The load-transfer device according to  claim 1 , further comprising a bolt member received in each aperture extending through the web member between the bottom surface of the top member and the top surface of the bottom member. 
   
   
       8 . The load-transfer device according to  claim 1 , further comprising at least one pad member disposed between the top surface of the bottom member and the bottom surface of the structure. 
   
   
       9 . The load-transfer device according to  claim 1 , wherein the structure comprises two adjacent double-T-shaped concrete structures. 
   
   
       10 . The load-transfer device according to  claim 9 , wherein the structure comprises a parking deck structure. 
   
   
       11 . The load-transfer device according to  claim 10 , wherein the load-transfer device is disposed in an expansion joint of the parking deck structure. 
   
   
       12 . A load-transfer device for a structure, comprising
 a top member comprising a bottom surface adapted to receive a top surface of the structure;   a bottom member comprising a top surface adapted to receive a bottom surface of the structure; and   at least one web member disposed between the bottom surface of the top member and the top surface of the bottom member, each web member comprising at least one stud member capable of extending through an aperture extending through at least one of the top member and the bottom member, each stud member capable of receiving a bolt member that is capable of fastening at least one of the top member, the bottom member or combinations thereof to the web member.
