Steel skeleton in Bushehr
The steel skeleton consists of steel, beam and column. The steel structure columns are located in both vertical and horizontal forms, and today the bodies of many buildings are covered by the country's cities. The most fundamental material used in steel steel skeleton is currently one of the most important materials in the construction industry. One of the most important benefits of steel that has made it used in the steel skeleton is high resistance, welding, ductility, bending, homogeneity and elasticity. Using steel skeletons in structures and buildings has caused To gain less weight and to show more resistance and strength against any impact, pressure and external factors such as the earthquake. So it can be said that steel structure structures have more relative balance.
The benefits of steel skeleton
- کاهش حجم فونداسیون
- کاهش قابل ملاحظه وزن ساختمان
- بالا بردن چشم گیر سرعت پیشرفت پروژه
- امکان بازرسی و تست های غیر مخرب در کلیه مراحل انجام عملیات
- بالا بردن میزان سطح زیر بنا
- امکان اصلاح و رفع عیب در هر مرحله بدون تخریب و از بین رفتن مصالح
- امکان انجام عملیات در شرایط مطلوب کارخانه و در نتیجه دقت و کیفیت بالا و مطلوب
Balanced material resistance
The strength of steel is the same in tension and compression and in shear it is good and close to tension and compression. In changing the position of the loads, the applied, compressive and tensile forces can be changed and the sections react well. But the strength of concrete is good in pressure and low in tension or shear. So, if areas are subjected to tensile force and are not armed, they will be destroyed.
Elastic properties
Due to the homogeneity of steel, its computational elastic properties have a practical example with a very good approximation. For example, the moment of inertia of a steel section can be reliably included in the calculations. However, in the case of concrete, these figures are not very specific and reliable.
Durability
The durability of steel is very good. If sufficient care is taken in the maintenance of metal buildings, they will be usable for many years.
Occupy space
In two similar buildings in terms of height and dimensions, the columns and beams of the metal building are smaller in terms of dimensions than the concrete building, that is, the level of occupation of the skeleton or dead space is higher in concrete buildings.
What is the nest?
Sole is a metal frame that is built on several columns. These columns are connected to the foundation by the column plate and prevent vibration in the structure. The other part of the columns is connected to the rafter or frame with flange connections. Rafters also facilitate the installation and implementation of sloping roofs. Most sports halls, warehouses, livestock and poultry production halls, etc. are built in the form of sheds. Based on the size of the opening, height, length and tolerance of rain and snow, the sheds are designed and implemented in various forms. Sule is derived from the English word industrial shed and is called a triangular structure.
Types of niches
Soles are metal structures with sloping roofs that are produced in different types and are used according to the type of use and place of implementation.
Truss nest
One of the simplest and most up -to -date niches is truss nest. The unique parameters in its construction make it distinct from other types of niches. In terms of materials used in the manufacturing, it is similar to the beam, but it is different in accurate technical calculations. Using up -to -date engineering expertise in the construction of trusseed nest has made the use of steel components in its lowest value, resulting in the weight of the structure reduced. Find and increase its endurance and durability. Failure to use a lot of steel parts in the truss does not undermine its safety and security at all. In this structure, all the forces such as wind, earthquake, etc. are distributed uniformly in all parts and are distributed in all parts. The same thing has led to prevent weight gain at a point.
The beam nest
The oldest and most used sheds are sheet beam sheds due to the passage of time. Of course, don't forget that in the past, due to the lack of sufficient engineering knowledge, these types of sheds were more common. Regarding the teaching of sheet beam sheds in the past, all university graduates used this method and method of construction. 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. The construction of sheet beam sheds is done using steel parts and black sheets. The shape of the roof of this type of shed is octagonal, which is created through welding.
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 spray insulation method causes the need for repair in a short period of time after the components are installed. and this will increase 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, so 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 humidity and weather changes, it is suggested to use other types of sheds.
