How to make an attic from truss metal roof. The role of the horizontal beam is to tie the truss together and carry the load that would otherwise be sustained by the support and vertical timber also known as the king post. Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. These are attached to the horizontal beam thus making up the triangle s base. Align the first metal roofing panel so that it overlaps the edging by 1 2 to 3 4 of an inch and is square to the roof line.

Typically the upper chords have different lengths in this particular type of truss that make the apex off center. The resulting truss will automatically extend out to the eaves. Install the roofing screws vertically along each rib in the panel. These steel joints are needed to support the overall truss.

While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. Its conventional triangular truss design is that the two sides are sloping up to the apex above with the struts known as the upper chords leading down from it. The rooms in the attic trusses depend on the length of the truss and the pitch or steepness of the roof. Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.

The conditions necessary to produce attic trusses are now in place. The more complex the truss framework is the greater quantity of these joints will be required. The longer the truss and the steeper the roof pitch the larger the room. To create an attic truss select build framing roof truss from the menu then click and drag a line that is perpendicular to the ceiling break lines and runs from exterior wall to exterior wall.

In this situation the walls of a finished attic space or room would go with the roof line. Extra support for the trusses can be made by placing a 2 by 4 inch piece of lumber from each truss on one side to the truss on the other side high enough to provide head room but low enough to provide support for the trusses.

The same thing is true for the bridge of the truss.
