In the construction of such sheds, sheet beams are used at long distances and the shingles are connected to the foundation separately. Also, more steel is used in this structure, which makes the sheds very heavy, and that is why it is named.
If we make a general division of the sheds in the world and want to divide the sheds based on the weight after construction, the sheds can be divided into the following three categories:
o Light shed
o Semi-heavy shed
o Heavy shed
In terms of efficiency, use in small and large projects, how to build and .. There are many differences.
Lightweight sheds are those that use prefabricated lightweight pipes, the structure of the building is prepared in the workshop, so the speed of work is very fast. In their construction, less steel is used. Which reduces the weight of the structure and also has acceptable strength.
The sheds that are made by sinusoidal beam method are very light and strong and can be built in large dimensions. In such sheds, one of the methods to increase the strength of the beam is to corrugate the soul, which is made of two blades. A flat, sinusoidal blade is used between them, increasing the strength of the beam.
The plates are made of steel, which are cut to the desired size by a "CNC" cutting machine and joined together by a welder and are formed into different shapes. Due to their low weight and high strength, sheet beams are more popular than beams in They are made of sheds. Among the types of sheet beams, we can mention sinusoidal beams, which have high resistance to corrosion and erosion and have a lower cost and weight. Shelters with metal frames are used.
• It is possible to recycle the parts of the shed after it is no longer used
• The use of overhead cranes, which are widely used in industry
He mentioned the construction of a multi-storey shed
One of the disadvantages of heavy sheds is the limitation in the size of the opening of the shed, the reason for which by increasing the opening of the shed more than (45 meters) disturbs the weight balance of the structure, which reduces security. We can mention the high cost of its construction.
Each shed has different uses based on the structure, and has its own advantages and disadvantages that you must consider based on the cost of construction of the shed, its area, consumables in construction and its needs and type of use to have the best choice. .
