  • Patent number: 4913594
    Abstract: The present invention is directed to a connection system for connecting a facing panel to a soldier pile so as to support the cut face of an excavation and provide greater tolerance for misalignment of the soldier piles with respect to the facing panels. The connection system also provides improved strength, and greater ease of construction. The system includes a first bracket coupled to the facing panel, the bracket having at least one stem portion with a horizontally elongated slot. A similar second bracket with vertically elogated slots in the base portion and a horizontally elongated slot in the stem portion is fixed to the soldier pile by a threaded fastener. A connecting plate connects the stems of the brackets together. Adjustment in the vertical, y-direction is provided by the location of the fastener on the soldier pile and the vertical slots in the first bracket.
