Patent ID: 10053854

Abstract:
The invention is a structural connector used as a component to construct an arch consisting of a plurality of closely adjacent, polygonal rows of stringer beams. The multiple row polygonal arch is a low-cost, general purpose support structure for bridges, shelters and arbors applicable to many cost-, time- or environmentally-sensitive situations. The invention is a Y-shaped connector, typically made of sheet metal, with three brackets, two upper brackets and a lower bracket, which collectively enable a union of three beams forming one node of the multiple row polygonal arch. Using these Y-shaped connectors to join the beams at each node creates the arch structure, and additionally provides the features of cantilevering, modularity, generic component shape, reusability and safety. The invention is applicable to a variety of structures such as: pedestrian and vehicular bridges, shelters, arbors, as well as jewelry, furniture and toys.
