Professional space frame manufacturer

Long-span steel 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, 186m×235m). A new type of space structur

  Space frame is a high sub-super-stationary space structure system with steel pipe and cast steel ball nodes as the main material, which has the characteristics of large spatial stiffness, good overall performance, uniform force transfer between rods, strong seismic capacity, etc., and can withstand the load from all directions; diverse space shape, can construct various shapes; simple installation, fast construction; can provide a large span of space in the state of point support. This large span, low cost structure type to adapt to the construction of gas stations on the demand for large and medium-sized canopy, thus in the late 20th century in the construction of gas stations has been rapidly promoted, and with the application of color pressure-shaped steel plate as a roofing material, its overall structural performance has also been perfectly presented, a time the design scale of the canopy is increasingly large, and some even up to 2000m2 or more.

At present, among the tens of thousands of flat space frames that have been built in China, small and medium spans account for the vast majority. For small spans like gas stations, there are countless flat space frame structure canopies that require large column grid spacing. At present, the flat space frame structure of the gas station canopy accounts for the vast majority of the market. The structure of the gas station itself is of the type with few columns and large spans, and the column network layout is flexible. The double-layer flat space frame structure can give full play to its advantages. Due to its superiority, in addition, the competition in the space frame industry is fierce, and the price tends to be slightly profitable, and the market purchase is also very convenient.

  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. LF is professional manufacturer and engineering company for space frame and steel structure pr
