Application Status of Large Span Space Frame Structures

Application Status of Large Span Space Frame Structures




As we all know, the large-span spatial structure is a structural form with broad development prospects. In recent years, with the use of high-strength and lightweight materials, the development of structural design methods, construction technology and the application of computer numerical simulation analysis have created extremely favorable conditions for the development of large-span spatial structures. At present, the large-span space structure is widely used in a series of urban landmark buildings such as airports, gymnasiums, convention centers, and large commercial plazas, which reflects the current trend of world architectural concepts.

The construction of space structures and the technologies used often reflect the level of a country's building science and technology. Some large-scale, novel and technologically advanced large-scale space structures have also become important symbols of a country's economic strength and social civilization. It can be said that the large-span space structure is the fastest-growing structural form in the past three decades.

The development status of the space frame structure

The development status of the space frame structure space frame   structure has been developed greatly in the last 30 years, and has been widely used inside and outside. space frame   structure plan arrangement is flexible, space shape is beautiful, convenient for building shape processing and decoration, decoration, can adapt to different span, different plane shape, different support conditions, different functional needs of the building.   Especially in the roof structure of large and medium span, the space frame   structure shows its superiority and is used in large number of large sports buildings, public buildings, industrial buildings, and also widely used in the roof of some small buildings, such as gas stations, toll stations, large canopies. In recent years, with the wide application of electronic computers and the development of computing technology, the design efficiency of the space   frame structure has been greatly improved. The construction and installation of the space

Cooling method of steel building structure

 Steel structure plant mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundation, steel roof truss (of course, the span of the factory is relatively large, basically now are steel structure roof truss), steel roof, pay attention to the wall of steel structure can also be maintained by brick wall. Due to the increase of China's steel production, many have begun to use steel structure plants, which can also be divided into light and heavy steel structure plants. Industrial and civil construction facilities made of steel are called steel structures. 1. Heat preservation and cooling: Steel structure plant insulation film can isolate most of the solar radiation and conduction heat, reduce the indoor greenhouse effect. Then the temperature of the plant is greatly reduced to improve the environment of the steel structure plant. The commonly used methods now have the following two choices: the steel structure

What is the truss welding method?

图片
  truss roof Most of the rods in joist structures are welded at the nodes. Before welding, the webs and chords need to be cut in advance according to the shape of the weld seam of each member to be welded, which requires cutting of the web ends and slotting of the chords. Since the joist structure is intersected by coherent line between the rods and rods, the shape of rod end section is complicated, so in the actual cutting process, two methods of mechanical automatic cutting process and manual cutting process are generally used.
