Iranian Experts Construct Prefab Concrete Sheds Resistant to Earthquake, Fire
“A prefabricated concrete shed is a structure that consists of prefabricated concrete parts. Prefabricated parts are made in the form of modules with standard dimensions for manufacturing plants and are used after transportation and installation on site,” Mohammad Imani, a researcher working at the research and development (R&D) unit of the company, told ANA.
He added that fast and easy installation with the ability to educate the general public on technical issues, the ability to compete with metal sheds in terms of price, and resistance to the most severe earthquakes in Iran, weather factors (snow, rain, storm, etc.), fire and the destructive effects of chemicals are among other features of this prefabricated structure.
Noting that these structures can also be repaired after an earthquake without collapsing, Imani said, “Prefab structures are cost-effective compared to conventional structures as the construction time is reduced.”
“It usually takes 5-6 months to build a structure, but the parts of these structures are bolted and installed on a flat surface in just two days. The carpentry process of these structures takes about 2 to 3 months. In total, a structure of 200 meters is built within 2 to 3 months,” he added.
In a relevant development last year, a group of engineers from a technological company in Iran had also designed and manufactured earthquake-resistant prefabricated houses which are movable and the safest place during tremors.
“One of the main needs of Iran is the light structures since these frames, in addition to resistance to earthquake reduce the weight of the structure by 50%,” said Ali Akbar Khademi, the director of business, design and development of the technological company.
He mentioned economic efficiency as another advantage of the plan, saying, “The price of these structures is 20% lower than traditional structures, while unlike prefabricated structures including canopies and the like, whether in concrete or metal form, these structures are able to save energy.”
“In the past, we used kenaf in production of these structures which caused the structure to crack; therefore, we used a type of wall based on nanotechnology to solve this problem in production of these structures,” Khademi said.
