  • Process and device for connecting I-beams
    Patent number: 6829872
    Abstract: A connecting plate for connecting I-beams together. The connecting plate contains at least two plates that each have a series of holes drilled in them. These series of holes are drilled offset from each other in each plate. The connecting plate can be in the form of a flat face, an L-shaped plate or a partially H-shaped plate. The offset holes on these plates allow the plates to be connected to a first I-beam first, and then connected to a second I-beam. This design allows a user to forgo coupling the first I-beam, the coupling plate and the second I-beam together all at the same time which improves the safety and efficiency of coupling I-beams together.
