Steel space frame is a kind of space structure . As early as 40 years ago , it has been applied abroad and gradually formed many stereotyped systems . Its application in many famous public buildings fully demonstrates the function and unique style of space frame. As early as the 1950s , China began to apply space frames , especially from the mid-1980s to the 1990s, the development was particularly rapid . The scope of application is mainly in airport terminals, large gymnasiums, light industrial plants, and machinery industrial plants. In recent years , with the rapid development of the aerospace industry , the requirements for long-span buildings are getting higher and higher . With the development of light roofs such as colored profiled steel plates and PVC waterproof systems , especially aerospace buildings have higher and higher requirements for indoor humidity. Building roofs have higher and higher requirements for the selection and anti-corrosion of steel structure space frames . What is more important is that the roofs of aerospace buildings have relatively large concentrated loads , and the ball joints of steel space frames need to bear large concentrated loads. Xuzhou space frame manufacturing company will discuss the advantages of using welded spherical steel space frames in large-span aerospace buildings by taking actual engineering as an example.

Aerospace buildings have the characteristics of relatively regular plane shape , large floor area , and large building space . The traditional structure is a plane structure system , that is, a single roof truss is supported on the column head , and the roof trusses are connected by roof supports to form a stable structure. system , the vertical load on the roof is all borne by the roof trusses and then transmitted to the columns . The support system does not participate in the force action in the vertical direction , and not only ensures the stability of the roof truss, but also transmits horizontal forces. It can be seen that the division of labor between the roof truss and the supporting system is clear , and each performs its own duties . This is obviously a waste of the use of material stress. Such a roof system composed of roof trusses and supports has very little horizontal stiffness, and the substructure can only be treated as a plane bent frame. The space frame is a space structure composed of rods arranged in an orderly manner , so it has high rigidity and good seismic performance . In addition , under any load condition , all rods participate in the force , making full use of the performance of the material , so as to save materials. Purpose. Light weight and low material consumption are its outstanding features. The most widely used aerospace building space frame is the flat space frame , and the flat space frame is divided into two types: the vertical (or oblique) cross truss type and the vertical (or oblique) pyramid type. Most of the aerospace buildings use flat-plate orthogonal and square pyramid space frames , mainly because of their simple shape and easy installation of skylights , which can meet the process requirements , are convenient to manufacture , and are convenient for overall hoisting during construction.
