Rafter system for industrial buildings and private houses

Starting the construction of the house, the owner always provides the final stage of the frame of the building - its roof. The roof consists of two parts: the supporting structure and the roof.

The load-bearing part of the roof is a rafter system consisting of a set of trussed trusses, on which the corners for fixing the girders are installed. Runs on industrial buildings are performed most often from channels having a bent profile. Then the roofs are fastened to the girders.

For industrial structures, there is a standard number of lengths of trusses: 6, 12, 18 to 48 meters in increments of 6 meters. Various designs of farms. For small spans of buildings, single-deck simple farms are usually performed. For large, over 18 meters, the rafter system consists of double-girder trusses.

Arched and hanging covers are used for the construction of hangars or covered stadiums, or other high buildings. They allow you to create a large free volume inside the building.

Before the construction of a building starts, the designers carefully develop its design. Carry out all the necessary calculations for the use of one or another material in the construction of the building, including the load on the roof.

The rafter system from the set of farms is selected based on all the recommendations of the designers. Usually, for industrial facilities, welded metal structures are used from standard profiles of beams, channels or corners. The choice of profile depends on the size of the building, the presence of static and dynamic loads and the climatic region of the area. In addition to the material, the designers propose the construction of farms.

The rafter system can consist of a number of hanging trusses. In this case, the support of the ends of the trusses falls on columns made of metal or reinforced concrete. The frame of the farm itself is made most often from the corners. The slope of the farm can be different - from 10 ° and above. A very high roof is not recommended, this will lead to an additional consumption of the material. All considered farms are mainly for industrial buildings.

For the construction of a private house there is such a thing as a rafter system of the hip roof. The difference between these roofs from single-sided or two-pitched roofs is the presence of an additional number of skates, which form hip rafters. Between them, the gable roof and the hipped rafters are joined by a ridge. For more reliable fixing of the roof, the outer rafters are reinforced with additional elements. We must not forget about the proportions of all elements. Do not perform all the designs themselves. They must complement each other.

Rafter system with own hands

Often, the owners themselves or with the help of helpers establish trusses in their future home. These are mostly wooden houses, in which the farms are gable. Depending on the owner's intentions, the roof can be made with a cold attic or have a space in which the attic will be constructed. A truss farm on a house that has two or more floors can be made with different sizes of ramps in a gable farm. To facilitate construction, the owner of a private home is increasingly being offered prefabricated trusses made in the factory. Then the quality of construction can significantly improve.
