Different Types Of Trusses Roofs

A Trusses roof is a structural framework that has designed offer strength and support to a roof. Therefore, roof trusses are one of the most important things in the roof construction. In this article, you will learn about different types of trusses roofs. Such as king post truss, queen post truss, mansard truss, truncated truss, bel-fast roof truss.

King Post Truss

In this type of truss, the central vertical post, known as king-post, forms a support for a tie beam. A king post truss is suitable for roofs of span varying from 5 to 8 meters.

King post trussed roof

Queen Post Truss

This truss differs from a king post truss in having two vertical posts, known as queen post. This type of trussed roof is suitable for spans varying from 8 to 12 meters.

Queen post trussed roofs

Mansard Truss

This truss is named after a french architect Francois Mansard. It is a combination of king-post and queen post trusses. The mansard truss is a two-story truss with the upper portion consisting of a king post truss and a lower portion consisting of a queen post truss.

Truncated Truss

This truss is similar to the mansard truss except that the top is formed flat, with a gentle slope to one side. This trussed roof is used when it is required to provide a room in the roof.

Bel-Fast Roof Truss

Also known as latticed roof or bowstring truss. This type of trussed roof can be used for long spans of about 30 meters, provided the light roof covering is used.

What Are The Different Types Of Roofs?

What Are The Different Types Of Roofs? The roof is the uppermost portion of the building which protects the building from rain, wind, and sun. Various types of roofs used may be divided broadly into three types: 1. Flat roofs 2. Pitched roofs 3. Shells and folded plates. Flat roofs are used in plains where rainfall is less and climate is moderate. Pitched roofs are preferred wherever rainfall is more. Shells and folded plate roofs are used to cover large column-free areas required for auditoriums, factories, etc. Brief description of these roofs is presented below: 1. Flat Roofs These roofs are nearly flat. However slight slope (not more than 10°) is given to drain out the rainwater. All types of upper-story floors can serve as flat roofs. Many times top of these roofs are treated with waterproofing materials-like mixing waterproofing chemicals in concrete, providing Coba concrete. With the advent of reliable waterproofing techniques, such roofs are constructed e

The Common Rafter and Purlin Roof

The Common Rafter and Purlin Roof As a civil engineer or roof contractor, you should aware of the construction of a roof and trussed roofs also types of roof construction in the industry. So, here our new article about roof rafter and purlin roof related to roof construction. The structure is most commonly used where there is a gable at both ends of the roof and is frequently to be found on terraced houses, as indicated in the below picture. This simple form of roof is illustrated in below picture. Its construction has been included here because of the now very common refurbishment of such houses. The wall plates are often simply bedded on mortar on either the inner skin of a cavity wall or, as is often the case with older terraced houses, on the inside edge of a solid 9 in. brick wall. Wall plates should be half lapped where they meet, and should not be less than 75 mm wide and 50 mm thick. They should be treated with preservative. Below picture shows typical plate co

The Coupled Roof, Ceilings And Trusses

The Coupled Roof, Ceilings and Trusses M oving off from early roof forms that provided each wall and roof in one unit, succeeding development showed a real roof designed on masonry or timber walls. the only type of roof was a coupled roof, consisting of 2 lengths of timber bearing against one another at the highest and resting on a plate at their feet. The timbers, known as couples, were pegged along at the highest with timber dowels and were equally pegged or spiked to the plate. The term ‘couple’ was used until the fifteenth century once the terms ‘spar’ or ‘rafter’ began to be used. The term rafter in fact continues to be wont to describe the piece of timber during a roof spanning from the ridge to the place. paced regarding four hundred millimeters apart tied solely by horizontal binders and tile battens. the easy couple was adequate for tiny span dwellings and steep pitches, however the outward poke force at the feet of the rafters caused stability issues with the walls
