Steel Structures (Manufactured Offsite)
Introduction
Prefabricated houses are homes built from standardized sections, which are manufactured in advance outside their location, and are subsequently shipped to their final location for final assembly.
There are a variety of different prefabricated houses, both due to the type of material used in their construction and their type of roof. What differentiates one type of prefabricated house from another is precisely the material used, especially in its structure.[1].
Approaching the definition
It refers to the parts of buildings already built in various industries. They can be made of different materials such as concrete, concrete, metal and wood, depending on the use that is going to be given to them. This, although it may seem like an inefficient way of creating buildings, reduces the cost and allows the construction of the building to be carried out in the fastest and most efficient way. It also considerably reduces environmental damage, since no noise is created, and the waste in the creation of the blocks is waste, which can be reusable.
This method acts like small LEGO blocks, which are arranged according to the required order, allowing constructions in two or three months, with greater durability and lower thermal conductivity. Making these buildings more efficient and durable.
The block, already finished and designed to fit with all the other blocks, is transported from the industry and taken by sea and land means. These come stacked in series and insured so that there are no problems when reaching its destination.
Prefabricated buildings can be living or storage spaces, among other various functions. They cover various needs and since they were designed using blocks, they can be combined with other modules or other constructions if more space is required or if space needs increase. In addition, the use of materials that do not require large amounts of energy consumption for their production, avoiding exaggerated weights, so as not to be like the old concrete and rod buildings weighing thousands of tons that were used in the last 30 years and return to a lighter and more manageable style. There is a modern technique that consists of taking reinforced concrete and pre-stressing it to make it much thinner and lighter; Thanks to this we save a large amount of material.
The results revealed that the environmental, economic and construction resources in the utilization of prefabrication technologies are significant compared to conventional construction methods, although there is still great room for evolution. This implies that greater use of prefabrication techniques can contribute to the industrialization of sustainable housing and construction.
