The supporting structure of the power structure of the roof

To design the roof is strong and quality, the roof structure must also be strong and durable without forgetting factor climate. The factors that support the strength of the roof structure is:

1. Material. Type of material that will be used for the roof structure is strong need to have strong, durable, lightweight and precise. Said the roof is able to hold strong when the size of the burden of work on the structure of the roof. There are three types of burden of work on the roof that is:
a. Burden that the burden of covering the roof structure and roof cover.
b. Wind load.
c. Materials include moving the burden of workers at the installation and maintenance of the roof.

2. Form of roof

Factors that determine the selection in the form of a dwelling house roof is rain, heat and wind. The form of the roof must be able to hold rain water downpours, hot sun and keep a strong wind encouragement. Among the three factors, the wind factor has a very big risk. When the blast occurred gale, the cover can only fly to the roof frame and roof can be picked up. Said the roof when the wind is able to hold the same from all directions. However, there are factors that affect the very strong pressure not to air, the altitude and slope roof buildings. the higher a building the more powerful the wind pressure on the building. So also with the roof slope, the greater its slope of the strong wind pressure. Ideal slope of a roof is 30 degrees.

3. The process of localization.
Processing through the roof must be considered and the requirements determined in accordance with the characteristics of the materials to be used. Characteristics include exposition and making the connection.
Exposition is set in the selection of roofing materials. The size and type of roofing material used must match the size of a roof expanse. The long expanse of the roof the size of the required materials. For exposition long exposition usual steel roof structure.
How to make the connection determine the strength of the roof structure. Note continuation to its continuation at the time of making the structure of wood is usually more., Especially for a long exposition. This is because the length of wood is limited, so need continuation. Continuation of wood can be a way in the nails, the bolt, or plate. Continuation should apply this technique in the right continuation.
