[0002] Steel structure building is a new type of building system, which breaks through the industry boundaries between real estate, construction and metallurgy, and integrates them into a new industrial system. This is the steel structure building system that is generally favored by industry insiders. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections to replace reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be factory-made and installed on-site, the construction period is greatly reduced. Because steel can be reused, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely adopted by countries around the world and used in industrial and civil buildings.

[0015] The beneficial effects of the present invention are as follows: 1. Compared with the steel structures of other steel roofs, the steel roof with two rows of continuous shuttle-shaped blades and the highest point of the second row of shuttle-shaped blades forming the highest slope tip are novel and unique, with a stronger sense of space, layering and rhythm, and more dynamic. The overall shape can be similar to a lotus throne, and has the artistic conception of golden Buddha light, mountains and sea of ​​clouds, and the confluence of three rivers; 2. The second and third rows of columns form an arc surface. Combined with the fact that the length and width of the second row of continuous shuttle-shaped steel grids are greater than those of the first row, the overall shape is more similar to the form of a lotus throne, which makes people entering the terminal building have a deeper impression when they see this outline. 3. The highest slope tip forms a shuttle-shaped skylight, which is open and transparent, and has good lighting; 4. At the construction nodes, a unique and novel combination of steel-concrete columns and steel tube concrete columns is used for support. Uniformly distributed bifurcated columns are used at the location of the gently cantilevered canopy grid frame, and unique eccentric bifurcated columns with high strength are designed at the steeper slope position on the second row of continuous shuttle-shaped steel grid frames. The apex of the eccentric support bifurcated column is higher than the vertical support bifurcated column, forming a new protruding claw-shaped support structure. The unique support system makes the scheme of this application convenient for construction; 5. In construction, the shuttle-shaped structure is divided into X-shaped segmented hoisting groups in the form of X-shaped intersections, which improves the construction quality and reduces the construction difficulty. In addition, the two ends of the X-shaped segmented hoisting group of the second row of continuous shuttle-shaped steel longitudinal beams at the eccentric bifurcated column are segmented into a docking section that cooperates with the eccentric support bifurcated column, which reduces the difficulty of large-span docking and the difficulty of high docking risk, and has high structural stability and low construction difficulty. 6. In the length direction of the first row of continuous shuttle steel grids and the second row of continuous shuttle steel grids, the present application uses column-beam hinged nodes. The overall structure takes the end of the finger corridor connecting the grid as the vertex and can have a small range of ups and downs, thereby having good seismic resistance. In addition, at the offset forked column, the rotating connection of the pin on the eccentrically supported forked column can cooperate with the column-beam hinged node to form a matched seismic resistance. In addition, the pin node on the vertically supported forked column enables the second row of beams to fluctuate up and down at four positions, namely, pin seat one and pin seat two, in the length direction of the beam, thereby achieving four-way seismic resistance and having good seismic performance. The forked column ball hinge node is used at the cantilevered canopy grid, which allows multi-directional rotation in the plane for seismic resistance. Therefore, the overall mobility of the present application is very long and has very good seismic resistance.
