Advantages of large span space frame structure

图片
The advantages of space   frame structure application The combination of reasonable form and high stiffness of the rods has strong seismic performance; the texture of the rods is lighter, which has the advantage of lightness under the premise of ensuring the stability of the space frame ; the space frame   rods and nodes are stereotyped; the arrangement of the components is flexible, etc. Bolt ball welded ball hybrid node analysis Bolt ball node and welded ball node both have unique application advantages, taking the hybrid node way that integrates two nodes can fully integrate multiple advantages and better meet the requirements of the project on the quality, adaptability and construction efficiency of the space frame   structure construction. When the space frame   structure adopts mixed nodes, the number of nodes of each type accounts for different ratios in general. Most of the ends of the rods are connected with bolted balls, and there are more bolted ball node...

Advantages of large span space frame structure

  First, short construction period The biggest advantage of the space frame structure is that all the components can be produced by the factory on-site splicing and installation, for the general scale of the smaller industrial plant only 45 days to 2 months, while if the reinforced concrete building is to be 8 to 12 months or so. Second, good seismic performance As the space structure is a flexible structure, light weight, and thus can effectively reduce the degree of seismic response and the impact of disasters, is extremely conducive to anti-seismic. Third, easy to dismantle and relocate Space frame steel structure building can be dismantled and relocated in a very short time with minimal loss, which is not possible with reinforced concrete building. It is because of the many advantages of space frame structure, and with the continuous emergence of new products of fire prevention and anti - corrosion in recent years, it has better solved the shortcomings of poor corrosion resist...

The space frame structure is a lattice-like high sub-super-stationary structure with multiple rods assembled according to certain laws. This structure appeared in Europe before the Second World War, and the real large-scale application was after the war. At that time, the space frame structure replaced the reinforced concrete structure in many occasions with its advantages of factory fabrication, on-site installation, convenient construction and labor saving. First of all, the space frame can play a spatial role, its stiffness and integrity is better than the general plane structure, and has excellent seismic characteristics; secondly, the space frame structure is more convenient to produce and install, and can be shaped industrialized construction. LF is professional manufacturer and engineering company for space frame and steel structure project with full capability of research, design fabrication, construction, supervision service for oversea project.   Do you have a constructi...

Application of foreign long-span steel space frame structures

      Long-span steel space frame structures are mostly used in multi-functional stadiums, conference and exhibition centers, expo halls, waiting halls, hangars, etc. The earliest flat space frame   with the largest span was the 91m×122m square quadrangular pyramid in the gymnasium of the University of California in Los Angeles in the 1960s. The largest double-layer reticulated shells are the Houston Astrodome (196m in diameter) and the New Orleans Superdome (207m in diameter) built in the United States in the 1970s. In the 1990s, a single-layer reticulated shell with the largest span in the world was built in Nagoya, Japan, with a building diameter of 229.6m and a structural diameter of 187.2m. Three-dimensional grids were used, and the nodes were rigid nodes capable of bearing axial force and bending moment. The largest indoor gymnasium in the world is the main gymnasium of the 1996 Olympic Games in the United States—the Atlanta Stadium (quasi-elliptical plane, 18...

Structural features of space frame

  The characteristics of the space frame structure are mainly reflected in the following aspects: 1. The structural force belongs to the three-line space force mode, which is not only reasonable in force, but also can be applied in a large-span environment. Compared with the one-way force-bearing planar structure, it has the advantages of less steel material and light weight. The deformation problem can be effectively reduced by increasing the stiffness, and the force uniformity of the reticulated shell is ideal; 2. The nodes and components of the space frame structure are relatively single, and the stereotyped characteristics are more obvious. The standard size can be determined according to specific requirements, and based on this, construction operations such as parts and prefabricated units are carried out. The level of mechanized processing is relatively high, and the overall construction period is relatively short. It is shorter and has obvious comprehensive economic advanta...

Current status of steel structure industry

图片
At present, with the rapid economic development and the acceleration of urbanization, new building materials and construction technologies are gradually becoming the mainstream of the construction industry. Among them, as a new, environmentally friendly, energy-saving and efficient construction method, steel structure buildings have received more and more attention. According to the "Steel Structure Market Development Trend Forecast" report published by Academia Sinica, it is expected that the steel structure construction market will continue to maintain a good development trend in the next few years. The report pointed out that since the construction industry is a large energy consumer, green and low-carbon development has become an important trend in this industry. Steel structures and prefabricated buildings are increasingly recognized and popularized in the industry due to their advantages of being more environmentally friendly, energy-saving, and efficient.
