The space frame structure is generally a high-order hyperstatically indeterminate structure, which can better withstand concentrated loads, dynamic loads and asymmetric loads, and has good seismic performance.
Fireproof coatings for space frame processing engineering have remarkable fireproof, heat insulation, heat preservation, water vapor, corrosion resistance and other characteristics.
As a new kind of construction, assembly steel structure buildings have a great significance in promoting the development of economic of our country.
Prefabricated steel structure building by the structure system, equipment and pipe space frame system, internal system, peripheral protection system integrated building; The structural system mainly takes steel members as the main skeleton, which are transported to the construction site for assembly and hoisting after processing in the factory. The components are connected by high-strength bolt connection, bolt connection and welding.
Tension beams on the top of independent columns are often used in indoor gymnasiums. Generally, the gable surface is relatively high. There are concrete beams tied in one direction at the top and half height of the column to separate the masonry wall and serve as the support of the parapet wall, while the other direction is Cantilever column.
Compared with the traditional concrete structure, the space frame structure has the advantages of large span, low weight, small steel consumption, and flexible shape.
As a modern high-end building structure, the light steel structure system is favored by designers and builders due to its rich and varied structural modeling effects, and is widely used in multi-storey buildings.
The space frame structure of the emergency dry coal shed in the coal pile area of the power plant is irregular pentagon in plane shape, with a length of 121.958m and a maximum span of 99.949m. The roof of the coal pile area is a double-layer flat space frame, which is supported by reinforced concrete columns around the perimeter. The space frame structure is in the form of quadrilateral cone cylindrical space frame shell structure, and the joints are connected by bolt balls.
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 roof of Chaoshan Airport terminal building is a spatial multi-curved welded spherical space frame structure in the form of positively placed quadrangular cones, with a length of about 315m along the direction of the central axis and a width of about 280m perpendicular to the direction of the central axis, of which there is an outdoor cantilevered roof of about 20m at the entrance of the south-eastern end of the terminal building.
Stainless steel is one of the strongest of the metal materials used in construction. Because of its excellent corrosion resistance, stainless steel allows structural components to permanently maintain the integrity of the engineering design.
The main loads of space frame steel structure are divided into three kinds, which are action load, permanent load and variable load. Generally speaking, the loads include the self-weight of the space shell structure, the self-weight of the roof maintenance structure, the load of the suspended equipment pipe and the load of the cat walk.
