Analysis and Advantages of Steel Structure Factory Building in terms of Noise Reduction and Fire Prevention

Steel structure plant is a structure composed of steel materials, is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust prevention processes. The components or components are usually connected by welds, steel bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, venues, high-rise and other fields. The steel structure is easy to rust, the general steel structure to remove rust, galvanized or paint, and regular maintenance.
In the case of steel structure construction, the elements must be considered first, but there are many, very much the level of sound insulation and noise reduction, it should be paid great attention to, the steel structure is the same, then the application of steel structure can really play a sound insulation and noise reduction effect?
(1) After adding this glass fiber cotton, it can reasonably block the flow of the gas in the middle, because the sound can be spread, when the sound is spread and there are blocks to block it, it can play a moderating practical effect, so that it can reduce the sound shell.
(2) After the addition of glass fiber cotton, it can change the actual effect of the audio in the whole process of sound transmission. A change to the frequency problem of audio can reduce it. In addition, for audio changes, it can also change the orientation, so it can be solved between each other.
Steel building
(3) For the steel structure, two walls can be applied on the design scheme, so that after having two walls, the sound can be solved twice on the above, which is much lower than the original one, and for the steel structure, it can change the ductibility and reasonably reduce the solid rapid propagation in the middle of the building. The reduction in speed means that the quality of sound is just beginning to diminish.
The steel structure commonly used in the construction industry has many advantages such as light weight, recycling and recycling of materials, but because the steel itself is not able to withstand high temperature, it affects the safety of steel structure buildings and hinders the development of steel structure manufacturers.
Introduction of fire resistance of steel structure materials:
1, the application of building refractory, weathering steel general steel fire resistance is poor, but through relevant technical means, change the material composition of steel, add specific components, change the structure and metallographic organization of steel, improve the fire resistance and weather resistance of steel itself. This is fire-resistant and weather-resistant steel. When the temperature of this steel reaches 600℃, the strength decreases by less than 30%, in addition, because of its better fire resistance table, the thickness of the protective layer can be properly reduced during construction, and even the anti-rust paint can be not applied, which can save a certain cost. The application of fire-resistant, weather-resistant steel is a cure, should be vigorously promoted, at present, China has a number of enterprises can produce building refractory, weather-resistant steel, which provides a good source of materials for steel structure buildings.
2, the use of strong fire resistance of the structural form and the fire resistance of the pure steel structure is relatively poor, but it can be properly combined with concrete to form a mixed component, or directly use reinforced concrete structure in some key parts. For example, concrete filled steel tube columns can be used, which can effectively improve the fire resistance limit, and the larger the diameter of the steel tube, the longer the fire resistance time, the 500mm diameter of the round steel tube concrete column, when coated with a thickness of 15mm insulation fire retardant paint can meet the fire resistance time of 3h. And such as floors and stairs with high fire protection requirements should still use reinforced concrete structure as much as possible.
3, adopt a reasonable steel structure fire protection treatment program steel structure fire protection construction practice should be reasonable, strong, economic, easy to construction, and conducive to decoration. When there is a non-combustible enclosure or divider on the same axis as the steel member, the non-combustible wall itself can be used to provide fire protection for the steel member, without the need to make another fire protection layer. For those exposed steel components, reasonable fire protection construction practices should be adopted.
4, the implementation of effective fire protection methods commonly used steel structure fire protection methods are outsourced concrete protection, steel wire mesh cement mortar, outsourced fire plate and spraying fire paint. External concrete protection is to completely wrap the steel member with concrete, and structural steel bars should be configured in the concrete to prevent the concrete from falling off. Steel wire mesh cement mortar fire protection is the use of metal mesh smeared 50# mortar as a protective layer, is also a traditional construction method. The fire-proof board can be made of fiber-reinforced cement board, gypsum board, calcium silicate board, hirudite SLATE and other non-combustible materials to wrap the steel members.
5, the fire resistance of steel structure depends on steel, steel itself does not burn, but also has good heat resistance, based on the physical properties of steel, steel structure this green building structure form has been quite popular in developed countries, do not let the fire resistance hinder the footsteps of steel structure manufacturers, we should actively take a variety of effective measures to improve the fire resistance of steel structure, Accelerate the development of steel structures.
Today, steel structure plant is widely used, mainly due to its own many advantages. The steel structure plant construction speed is faster, the appearance is beautiful, the premise is to prepare the construction guarantee position in advance. With the continuous improvement of the company’s production and manufacturing and warehousing and logistics land area requirements, the reasonable layout of space layout regulations are getting higher and higher. Therefore, the traditional construction method has been unable to consider the current area, but gradually eliminated.
The cross-sectional area of the steel structure plant is small, and the reasonable layout provisions of different indoor Spaces can be considered. The vertical pole area is small, and the indoor applicable space area is also expanded. Due to the characteristics of the steel structure plant building decoration materials, the construction of the frame shear wall and the application area of the interior space can be guaranteed, the plant mostly uses cold-drawn thick wall steel components, and part of the load uses cold-drawn galvanized steel plate with good corrosion resistance, which reasonably prevents the damage of rust in the entire construction and application process of the thick steel plate. Reasonably extended the service life of light steel structure plant manufacturers introduced steel structure components.
In addition to the advantages of spatial layout and carrying capacity, the steel structure plant also has good fire resistance. After fire prevention treatment, the fire prevention ability of steel components can be improved, and the entire process of steel structure being destroyed can be increased, giving everyone enough time to escape. Moreover, its raw materials are mostly reproducible resources, recyclable, reducing raw material consumption, in line with the current policy of sustainable development of our country.
There is also the steel structure plant can be constructed all year round, less affected by seasonal factors, more common in work construction, less harmful to the surrounding environment; Steel structure components are also transported to the site after production and processing in the processing plant for installation and construction, with high precision and fast speed, reducing the construction period, reducing time and cost input.
Moreover, there are many elements of the application of steel structure site, more and more companies and contractors choose steel structure engineering construction, I believe that the future application of steel structure market prospects will be broader, will follow the pace of The Times, and continue to improve the construction quality of steel structure and service projects, and build more excellent works.
