Brief introduction of corrosion and anti-corrosion of space frame steel structure

Image
  Because the space frame  steel structure has the advantages of good mechanical properties, strong load-bearing performance, simple manufacturing, easy to adopt industrial production, short construction and installation period, and good sealing performance, it has been widely used in national economic construction, such as l ong -span structure (coal bunker , stadium roof trusses, etc.), light   space frame  steel structures (large and medium-sized workshops), high-rise buildings (commercial buildings, office buildings, etc.). However, during the use of steel structure, and the environmental medium in which it is prone to biochemical, electrochemical or physical effects, resulting in the deterioration of the material and the destruction of steel structure failure, people often called the corrosion of steel structure.  People have realized that the steel space frame  structure used by humans is rarely damaged due to pure mechanical factors (such as tension...

Explain the development law of space frame structure in detail

Image
  The development of the space frame structure is closely linked to the needs of life and production, the level of science and technology, and the development of material conditions. It has undergone a long development process.It has become one of the most important and active development areas in the architectural structure discipline of the 21st century. Reviewing the development process of the  structure, we can summarize some development laws of it. The span of the space frame structure is getting bigger and bigger.From St. Peter’s Basilica in Ancient Rome to the "Millennium Dome" in London, England,its diameter has been expanded from 42m to 320m.Behind every innovation and development of the space frame structure, it is accompanied by the continuous increase of the span of the building.In recent years, more and more buildings have been built or under construction that exceed the span of the hectometer, and various forms of space frame structures have developed to super-...

Quality control elements of steel space frame structure

Image
With the acceleration of the social modernization process, the steel space frame structure building has been extensively developed in the construction industry by virtue of its unique advantages, playing an irreplaceable role. SAFS steel structure will give you a talk about the quality control elements of the steel space frame structure. The project quality of space frame is prone to problems mainly as follows: When the flange plate and the thickened or widened connecting plate are butt welded, the transition of the inclination should be made according to the requirements; The connection surface of the end plate is rough, the cutting is not flat, or the control is improperly welded with the beam column flange plate, which causes the end plate to be warped and deformed, causing the contact surface between the end plates to be inconsistent, and the connecting bolts are not strong.Therefore, the structural properties such as bending, tension, and shear resistance of the node cannot be sa...

5 principles for determining the height of a space frame structure

Image
What are the principles for determining the height of the space frame structure ? Today, SAFS steel structure will take you to understand the five-point height determination principle: 1.  The height of the space frame structure is related to factors such as roof load, span, plane shape, supporting conditions and equipment piping. 2.  When the roof load is large and the span is large, the height of the space frame should be larger. 3.  When the plane shape is round, square or close to square, the height of the space frame can be smaller. When the plane is long and narrow, the unidirectional force transmission is obvious, and the height of the space frame should be larger. 4.  The height of the point-supported space frame is larger than that of the peripheral support. 5.  When there is a passage pipe in the space frame, its height must meet the requirements. The above content is the principle of space frame height determination, I hope it can really help you. If ...

Steel structure correction forming process

Image
  The steel structure we use has many processes during processing. Correction and forming are the most important. Let's understand it together. 1. Correction 1). The cold correction of the finished product is generally performed by mechanical forces such as flange levelers, straightening machines, hydraulic presses, and presses. 2). Flame correction, there are three heating methods: point heating, linear heating and triangular heating. ①The heat correction heating temperature of low carbon steel and ordinary low alloy steel is generally 600~900℃, And 800~900℃ is the ideal temperature for thermoplastic deformation, but it is not allowed to exceed 900℃. ②Medium carbon steel will crack due to deformation, so medium carbon steel generally does not need flame correction. ③Ordinary low-alloy steel should be slowly cooled after heating and straightening. Picture taken from: www.safsteelstructure.com 2. Forming 1). Hot working: For low carbon steel, it is generally 1000~1100℃, and the term...

Problems in building space frame steel structure

Image
        The steel structure space frame  has been recognized by everyone in the market now. Because it has better energy saving and environmental protection characteristics, and it has begun to get everyone's attention. However, for steel structure manufacturers, they believe that there are still many problems in front of them, and these problems still need to be improved. So what are the main problems in the construction process? Steel structure manufacturers believe that although the current construction of steel structure space frame s has the effect of energy saving and environmental protection, the understanding of the entire industry is not high, so it needs to be improved. Some time ago, Canada and the United Kingdom have already published many articles to publicize the advantages of steel space frame s. In the current market, the design concept cannot be fully adapted. It mainly because buildings and functions have certain uniquenessin the planning proce...

How to judge whether the steel structure space frame company has the strength?

Image
For the construction party or some owners when they choose the steel structure   space frame  company, they basically have no   idea . I don't know how to judge the overall strength of the steel structure space frame  company. Below I can give you four points for reference. 1. It can be judged from the company's registered capital. A powerful company has relatively good investment in related capital, site and supporting construction equipment, and their strength and comprehensive capabilities should not be underestimated. 2. Look at the design qualifications of this company, generally qualified and high-quality design and construction teams, with high-profile designers, are relatively high-level, so you can judge from the company's steel space frame  designers. 3. Looking at the company's engineering cases, the success of general engineering cases is very important for the comprehensive ability assessment of a space frame  project, and it can well show the ...
