The steel structure of a single-story factory building is generally a spatial rigid skeleton composed of purlins, skylight frames, roof frames, brackets, columns, crane beams, brake beams (or trusses), various supports, and wall frames and other components. These components can be grouped into the following systems according to their roles: (1) Horizontal plane frame –…
I. Rebar Rebar is a steel bar with ribbed surface, also called ribbed steel bar, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. Among them, rebars are categorized into Grade I rebars (round bars), Grade II rebars (HRB235), Grade III rebars (HRB400), and Grade IV rebars (HRB500). Ribbed steel bars…
Steel structure connections include riveting, welding, hybrid riveting joints, bolt connections, etc. The advantages of riveting are reliable force transmission, good toughness and plasticity, easy quality inspection, and strong resistance to dynamic loads. But the riveting method also has its drawbacks: complex structure, steel and labor consumption. Steel structure is a type of building structure…
1、 Preparation before budgeting For a beginner to make a steel structure budget, some knowledge should be essential. Firstly, one should know the construction process of the steel structure, including how to obtain materials, how to cut materials, and how to construct each process. This can prevent disclosure when calculating the engineering quantity in the…
Over the past 30 years of reform and opening up, China’s steel structure manufacturers have achieved rapid development in their manufacturing industry. Currently, this industry is in a historical development period from being a major manufacturing country for steel structure manufacturers to a manufacturing powerhouse. There are nearly 3000 qualified steel structure manufacturers and enterprises…
On July 21st, shipment continues in the whole day.
There are many types of glass curtain walls, which can be divided into the following types based on different factors such as glass type, installation method, and support structure:
1、 Chemical composition 1) Chemical composition Carbon: The main component that constitutes the strength of steel. If the carbon content increases, the strength of the steel will improve, but the plasticity, durability, cold bending function, weldability, and rust resistance of the steel will decrease, especially the impact resistance at low temperatures. Manganese and silicon: favorable…
(1) Before processing the steel structure, the construction personnel shall prepare the process regulations and the chief engineer shall approve them. Carefully inspect the process preparation of each process, and prepare and mutually review the processing drawings. (2) Inspect various materials and tools required for processing, and ensure that the process equipment meets the requirements…
The advantages of high strength and good ductility of steel determine that steel structures have the characteristics of light weight, good seismic performance, and large bearing capacity. At the same time, steel structures can be processed on site, with a short construction period, and materials can be recycled. Therefore, steel structure buildings have been widely…
