Truss nest
One of the simplest and most up-to-date sheds is the truss shed. The presence of unique parameters in its construction has made it stand out from other types of sheds. In terms of the materials used in the construction, it is similar to the sheet beam shed, but it is different in performing accurate technical calculations. The use of up-to-date engineering expertise in the construction of the truss shed has caused the use of steel parts to be at its lowest, resulting in a reduction in the weight of the structure. It is found and its endurance and durability increases. Not using a lot of steel parts in the truss shed does not affect its safety and security in any way. In this structure, all the external forces such as wind, earthquake, etc. are distributed uniformly in all parts, and this causes It can prevent the accumulation of weight in one point. Among the advantages of building a truss shed are low transportation costs, design of an arched or octagonal roof, ease of installation by a crane in any number, lower final price, and its implementation without Limitation in wide openings without columns, lack of restrictions in design and the ability to open the structure easily. In the construction of this type of shed, the opening can be created in the desired dimensions and size according to the customer's taste.
The beam nest
According to the passage of time, the oldest and most used sheds are sheet beam sheds. Of course, it is worth mentioning that in the past, due to the lack of engineering knowledge, these types of sheds were more common. Considering the teaching of sheet beam sheds in the past, all university graduates used this method and construction method. For this reason, the number of sheet beam sheds in the country is more than other types. The construction of this type of sheds is obsolete in European countries, but it is still used and built in Asian countries such as Iraq, Afghanistan, Iran, etc. Sheet beam sheds are made using steel parts and black sheets. The shape of the roof of this type of shed is octagonal, which is created through welding. The construction of this type of shed is faced with many disadvantages: it is not possible to construct an opening with a length of more than 45 meters. The weight of this shed is higher than usual due to the use of many parts, and as a result, its cost is higher than other structures. According to the explanations given, people prefer to replace the sheet beam shed with another shed structure. It is recommended that sheds with a span of less than 18 meters through a sheet beam have a lower cost to build due to having fewer parts. For the size of the opening, use a sheet beam shed.
UBM niches (UBM)
Formed and rolled galvanized sheets are used in the construction of this type of shed. The sheets are connected to each other by a special device called Samir. This is done to fasten the sheets together. But the thing to think about in this part is the possibility of the sheets being separated from each other due to contraction, expansion and strong vibrations caused by the force of the wind. The most common application of this type of shed is for structures with a maximum opening of 30 meters. The low resistance of this type of shed against air humidity, rain and snow due to the use of the spray insulation method causes the need for repair and maintenance in a short period of time after the components are installed. and this itself causes an increase in consumption costs. The insulation used in this type of sheds is flammable and absorbs pollution. In addition, they will not have the ability to disinfect in any way, for this reason, this type of shed should not be used in hospitals, food processing, poultry or livestock industries. One of the advantages of the UBM shed is the low cost of its construction compared to other sheds. but due to the length limitation of the opening and the lack of resistance to moisture and weather changes, it is recommended to use other types of sheds.
