主权项

1. A load transfer device connecting at least first and second concrete elements comprising:
said first concrete element having a first surface closest to said second concrete element; said second concrete element having a first surface closest to said first concrete element; a first load transfer member having a first end and a second end, said first load transfer member only in contact with said first and second concrete elements at said first and second ends respectively; a second load transfer member having a first end and a second end, said second load transfer member only in contact with said first and second concrete elements at said first and second ends respectively; wherein said first load transfer member and said second load transfer member are positioned at an angle to the normal of said first surface of said first concrete element and at an angle to the normal of said first surface of said second concrete element; wherein said first ends of said first and second load transfer members are at least partially embedded in said first concrete element in a spaced relationship with one another and said second ends of said first and second load transfer members are at least partially embedded in said second concrete element in a spaced relationship with one another; and wherein said first and second load transfer members transfer all loads independently of each other.
