Bolt ball joint space frame

 Space frame structure because of its novel structure, reasonable force, light weight, small amount of steel, a large number of steel structures have emerged from the late 1980s, increased by about 80 to 1 million m2 every year. Widely used in large sports venues, exhibition centers, theaters, shopping malls, terminal buildings, waiting halls, factory workshops, warehouses, TV towers, etc. The domestic space frame structure is mainly divided into: welding ball joint space frame and bolt ball joint space frame. The bolt ball joint space frame has a large amount of processing in the factory and convenient installation on site. It is suitable for the special-shaped structure with tight on-site construction period, restricted construction conditions and electricity consumption, complex grid shape and difficult pole positioning. This paper focuses on the bolted ball joint space frame.

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision machining,

What are the advantages of steel over traditional concrete?

  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more flexibility in creat

Lifting construction of the starting unit frame of the large-span arched space frame

The space frame structure has good structural performance and a wide range of applications, especially for the installation of long-span steel structures. It has the advantages of saving steel, manufacturing technology, and convenient installation and construction. It is widely used in large-scale power generation facilities, petrochemical, coal f ields and other industries. In the construction of coal yards, in the past, most of the coal yards were piled in the open air, which caused great environmental pollution and affected the normal use of the coal yards. The coal raw material workshops of thermal power plants required relatively large building areas and spans (currently, the domestic span has reached 120m above), so that the steel space frame shell structure is widely used in the raw material dry coal shed workshop. The shell structure of the space frame of the dry coal shed has the characteristics of large span and high vertical height. During the construction process, it is ne
