The second layer is affixed to the first layer with first layer fasteners and the third layer is affixed to said second layer with second layer fasteners. The first layer fasteners pass through the second layer to engage the first layer from a first side of the roof truss and the second layer fasteners pass through the third layer to engage the second layer from the first side of the roof truss. Therefore, the truss components may be field assembled without having to turn the partially assembled truss. The use of common components and fasteners and the ease of assembly provide an economical alternative to known truss systems. | 09-09-2010 |
