In this type of prefabricated buildings, during the design, the building is divided into two or more portable parts and all construction steps are done in the factory and then the building is transported to the project site in several pieces and assembled there to each other in the form of bolts and nuts. The size and plan of these buildings can be designed based on desires and orders.
The prefabricated building assembled in the factory has a series of features during implementation. These features are considered the principles of prefabricated building construction.
In the prefabricated building assembled in the factory, the profiles used in the foundation are bent by cold rolling and these parts are connected with bolts and nuts at the project site. These profiles are designed with software such as Solid work and Abacus.
Iron profiles form the skeleton of the prefabricated building. Also, their connection point is punched and connected with bolts and nuts during execution. The size and shape of skeleton profiles are designed based on global standards. Also, the profiles should not have pollution on themselves; Therefore, before starting work, it is necessary to clean them of any contamination and to protect them from rotting, use furnace paint to paint them.
For the metal grid of the floor, a sandwich panel with polyurethane insulation and shadowline design is often used. Parquet or any material desired by the customer is used to cover it.
Aluminum or PVC framed doors and windows are used in these prefabricated buildings. PVC profiles together with double-glazed windows are very effective in insulating the interior of the building thermally and acoustically.
The roof of the prefabricated building assembled in the factory is usually made in a sloping manner and for its covering, a variety of sandwich panels are used. The walls are also made of prefabricated sandwich panels.
The prefab building assembled in the factory has significant advantages compared to other buildings. Some of these benefits are:
In order to estimate the price of a prefabricated building, several factors must be considered. Factors such as the thickness and quality of the steel used and the prefabricated materials used in the walls are effective in determining the price. On the other hand, the roof covering and the type of windows are among the factors that determine the price of a prefabricated building assembled in a factory. But in general, compared to the types of buildings built with traditional materials, they have a lower price.
Here, an attempt was made to discuss the advantages of a factory-assembled prefabricated building. Today, these buildings have been welcomed by people and organizations due to reasons such as natural disasters and the economy ruling the society, considering the existing situation. These buildings are more interested in project engineers due to their high execution speed and lower cost. Anyway, to order a prefabricated building, whether factory assembly or concrete foundation, it is necessary to get help from experts and specialists in this field. You can contact the experts of Arya Baron for any advice in the field of buying prefabricated buildings.
Frequently Asked Prefabricated building assembled in the factory
It is better to minimize the pre-assembly and assembly operations in the factory because assembly in the factory will face you with limitations. For example, the assembly structure in the factory should not be large in size, because in this case it may not be possible to move it to the project site. Therefore, it is better to assemble structures with larger dimensions and area on site. How to transport parts of prefabricated buildings is also very important.
Hierarchy of transportation and relocation of these structures for installation on site must be followed properly because there is a possibility of damage to the parts of these structures if proper and principled transportation is not followed. In some cases, the parts of a prefabricated structure may be made in a factory under a certain temperature and may suffer damage if the temperature of the outside environment changes. Therefore, it is necessary to pay more attention to these items during the construction and assembly of these buildings.
Welding joints are not used to connect different parts of these structures to each other, that’s why they are also called bolt and nut prefabricated buildings. The connection of these structures with the help of bolts and nuts has made their use suitable for the place where it is not possible to build in the traditional way. Factory assembled bolt-on prefab buildings are often built with the following uses:
In the past, the use of bolted structures was limited only to industrial complexes and sheds, while today, with significant progress in the construction of prefabricated structures, we can see wider uses of bolted prefabricated buildings. Structures with residential, office and commercial uses can also be assembled in the factory. The following are the advantages of bolted connections:
Arya Baron is currently one of the top national brands in the field of design, production, and construction of sandwich panels, prefabricated buildings, cold storage doors, and so on. Through utilizing specialized technical personnel and fully automated production lines, this brand has managed to manufacture products with global standards in Iran and export them to neighboring countries.
One of the main features that factory-assembled prefabricated buildings must have is their lightweight nature. Clearly, if heavy materials are used in the construction of these buildings, transporting and relocating them to the project installation site will not be feasible. Accordingly, factory-assembled prefabricated buildings are of the lightweight prefabricated building type. Aluminum and its alloys are considered strong and lightweight metals appeared to be the most commonly used materials in the construction of prefabricated buildings where all construction stages take place in the factory or workshop.
However, given the high cost of aluminum and its alloys, emplying this metal for manufacturing prefabricated structures does not seem very economical. Hence, metals with properties similar to aluminum but more cost-effective may be utilized for the construction of factory-assembled prefabricated buildings. Cold-rolled steel is one of the most widely used materials for manufacturing these structures.
Different components such as parts, panels, and modules can be used either alone or in combination in prefabricated construction. The best method for constructing prefabricated buildings with these components is to manufacture the various parts of each building in large dimensions at the factory and then transport them to the workshop for installation. In case of deciding to use the panel system for manufacturing these structures, it is worth noting that this material can achieve up to 60% prefabrication, with the remaining 40% needing to be completed on-site.
Meanwhile, 3D components, i.e. modules, can increase prefabrication up to 85%. If only modules are employed in a project to construct these prefabricated buildings, prefabrication can even increase up to 95%. The remaining 5% is dedicated to foundation operations and workshop equipment.
