 1. Production of hollow steel balls and steel pipe rods In order to ensure the installation and quality of the space frame and bolt ball processing, all hollow steel ball joints and steel pipe rods are processed centrally in the factory. The steel ball is made of tire film, and the raw material is No. 45 steel. Using lathe cutting, machining tolerance is: diameter deviation ±1mm, ball ellipticity deviation <1mm. The allowable deviation of the length of the steel pipe is ±1mm, the end face of the steel pipe must be perpendicular to the axis of the rod, the allowable deviation is 0.5%R(R is the radius of the steel pipe), the maximum bending of the steel pipe must not be greater than 1/1000 rod length. 2. Installation of steel space frame Based on and guided by the theory of computer simulation, a detailed assembling scheme is made. According to the characteristics of the engineering structure and the layout of the construction site, scaffolding work platform is set up on the gro...

  Because most of the space frame   engineering uses steel structure materials, due to the influence of paint and natural environment, rust corrosion is very likely. The following explains how to do anti-corrosion measures in the construction of large-scale space frame   projects. First, the causes of corrosion affecting large-scale space frame   projects The first is the coating aging problem of the space frame   engineering, no matter what kind of material basically has the characteristics of aging, and this anti-corrosion coating is no exception, and the aging of this coating makes the failure of the anti-corrosion coating of the steel structure, and then makes the rust affect the life. In addition, a natural environmental factor around the space frame   project, if the air around the steel structure plant is relatively humid, then it will inevitably make the steel structure gradually rust under the erosion of water and air. In addition, if the pollutio...

 In a sense, steel structure can also be divided into two categories, one is light steel structure, the other is heavy steel structure. And they come from many sources, but how exactly do they differ in detail and architectural use? Come here. I'll show you. First, light steel, for steel structure, light steel is not strictly defined, because its main building structure can be said to be composed of a combination of a variety of structures, such as cold-formed thin-wall steel, hot-rolled thin-wall steel, welded and high-frequency welded cold-rolled thin-wall steel structure and so on. The second is heavy steel, the definition of Pusteel is also the same, there is no unified standard to measure the difference, can only say that many experienced designers or projects are not clear, but from some data reference can be seen that the difference is very big, such as in the steel structure of the plant, if the weight of more than 25 tons, then it is heavy steel. In addition, in the use a...

 "A new building system can open up the industry line between construction, metallurgy, machinery and equipment manufacturing, new building materials and disaster prevention and reduction industries, become a national strategic resource reserve, and integrate innovation into a strategic emerging industry." Steel structure houses are conducive to economic transformation and upgrading and sustainable development, and need to accelerate cultivation and development." This is a few years ago, the industry is generally optimistic about the steel structure building system. Steel structure residential general system for residential use, with unique advantages, including: first, light weight. Steel structure housing can reduce the building weight of about 30%-25%, which is conducive to the construction of high-rise buildings, especially in places with low geological carrying capacity and high seismic intensity, and its comprehensive economic benefits are better than ordinary res...

The steel structure will be subjected to various forms of action (load, uneven settlement of the foundation, temperature, etc.) during use, so the steel should have good mechanical properties (strength, plasticity, toughness) and processing properties (hot and cold processing and welding performance) to ensure the safety and reliability of the structure. There are many kinds of steel, and only a few kinds meet the requirements of steel structure, such as Q235 in carbon steel, l6Mn in low alloy steel, and 20 manganese vanadium steel (20MnV) for high-strength bolts. Performance index 1. Strength The strength index of steel is composed of elastic limit σe, yield limit σy, and tensile limit σu. The design is based on the yield strength of steel. High yield strength can reduce the weight of the structure, save steel, and reduce the cost. Tensile strength σu is the maximum stress that steel can withstand before failure. At this time, the structure loses its performance due to large plastic...

 Prefabricated steel frame commercial buildings are ideal for agricultural projects, warehouses and industrial buildings. This is because they are fast and cheap to build. This type of steel structure construction has many advantages. So, read on to find out why steel construction might be the choice for your next construction project. Faster construction time Prefabricated commercial buildings (PEBs) can be completed much more quickly than other construction methods. This is due to their use of high-strength steel and stacked conical cross sections. Steel construction general contractors also utilize computerized processes to ensure standardized and accurate design. The structure of these buildings is clearly laid out in the diagram so that all the different parts can be easily assembled. All components and materials are pre-cut so that they are ready for construction on site. As a result, PEBs can be assembled much faster than other, more traditional modes of construction. Pre...

 1. High strength, light weight The strength of steel is high, and the elastic modulus is also high. Compared with concrete and wood, the density and strength of steel are relatively low, so under the same stress conditions, the steel structure has the characteristics of small cross-section, light weight, convenient transportation and installation, and is suitable for large-span, high-height and heavy-duty structures. 2. Good toughness, high reliability The steel is suitable for bearing impact and dynamic loads and has excellent seismic performance. Its internal structure is homogeneous and almost isotropic. The actual performance accords with the calculation theory. Therefore, the reliability of the steel structure is higher. 3. High degree of mechanization Steel structural components are easy to manufacture in the factory and assemble on site. The steel structure component factory has high precision, high production efficiency, fast assembly speed and short construction period. S...
