Types Of Wood Roof Trusses

It is usually used for roof construction some common trusses are named in accordance with their web configuration.

Types of wood roof trusses.

The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers. Steel rods are used as tension members. The more complex the truss framework is the greater quantity of these joints will be required. The cord size and web configuration are determined by span load and spacing.

A variety of the trusses shown above fit into the common or gable truss category including the king. This particular truss is made out of wood most of the time but it can also be built out of a combination of steel and wood. Studio two bearing points truss. The king post truss is mainly adopted for short spans less than 6 m.

This method allows for greater energy efficiency. The raised heel roof truss reduces. Below are the common types of roof. It is usually built of wood completely or of wood combined with steel.

As the name implies this roof appears flat in structure although it is always pitched at a wider angle to allow water runoff. Pitched truss or common truss characterised by its triangular shape. There are two fundamental types of trusses i e. Common types of roof trusses parallel chord roof truss.

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. The same thing is true for the bridge of the truss. Total load psf duration factor live load psf roof type 55 1 15 40 snow shingle 55 1 15 30 snow tile 47 30 snow 40 20 snow 1 25 20. These steel joints are needed to support the overall truss.

Most common types of roof trusses gable trusses. Alpine truss designs are engineered to meet specific span configuration and load conditions.
