Steel Space Frame Factory - China Steel Space Frame Manufacturers and Suppliers

The space frame can be divided into two types of nodes: welded ball space frame and bolt ball space frame. The flat space frame has a flexible plane shape and can be designed into various shapes. According to the different settings of the web members, it can be divided into: cross truss system, quadrangular pyramid system, triangular pyramid system and some other systems. When the chord of the space frame is perpendicular to the boundary, it is called a positive space frame, and when it is oblique to the boundary, it is called an oblique space frame. Many countries in the world have successfully built many space frame structures in large and medium-sized roofs, such as the expositions in Canada and Japan, the Congress Hall in Chicago in the United States and the hangar in London in the United Kingdom. Economic, the former Soviet Union also adopted prestressing in the space frame. In a word, the space frame structure has become one of the most widely used new structures in the modern world.

Mainly divided into three categories: the first category is composed of plane truss system, there are four forms of two-way orthogonal space frame, two-way orthogonal oblique space frame, two-way oblique inclined space frame and three-way space frame ; The second type is composed of quadrangular pyramid units, and there are five forms of positive quadrangular pyramid space frame, positive evacuated quadrangular pyramid space frame, inclined quadrangular pyramid space frame, checkerboard quadrangular pyramid space frame and star-shaped quadrangular pyramid space frame. ; The third category is composed of triangular pyramid units, and there are three forms of triangular pyramid space frame, evacuated triangular pyramid space frame and honeycomb-shaped triangular pyramid space frame. The shell space frame structure is divided into cylindrical shell space frame, spherical shell space frame and hyperbolic paraboloid shell space frame according to the shell surface form. The space frame structure is divided into steel space frame, reinforced concrete space frame and combined space frame composed of steel and reinforced concrete according to the materials used, among which steel space frame is used more.
