Angle Spreader for Trusses

摘要

A truss hinge that allows hinging between truss parts, and also allows configuration into a different size, and spreads the angle of the truss open ends. One embodiment uses a first plate, having a connection part to a first truss, where the connection part is adapted for connection to a first truss. A second plate is movable relative to the first plate. The second plate also has a second connection part adapted for connection to a second truss. An angle setting part forms a connection between the first plate and the second plate, that holds the first plate relative to the second plate at any of a number of different relative locations between the first plate and the second plate. The plates include angle markings to set the connections.

主权项

1. A method of adjusting angles between multiple trusses of a dual pipe truss that two parallel cylindrical pipes, comprising:
attaching a first plate to first and second cylindrical and parallel pipes of a first truss using a connection part; attaching a second plate to first and second cylindrical and parallel pipes of a second truss, in a way that is movable relative to said first plate, said second plate also having a second connection part adapted for connection; hinging between said first plate and said second plate using a hinging part that hinges said second plate relative to the first plate in a way that allows the second plate to move relative to the first plate while the first and second plates are each connected to said first and second pipes of said respective trusses and holds said first and second plates relative to one another; and setting an angle between said first plate and said second plate, by forming a connection between said first plate and said second plate, that holds said first plate relative to said second plate at any of a number of different relative locations between said first plate and said second plate; where each of said first plate and said second plate include angle markings thereon as text which indicates an numerical indication of an angle which will be formed between trusses that are connected to said first plate and said second plate when said angle setting part is set to one of said connections.
