[0017] Step one: Cast an arcade at the designed location, and make openings along the longitudinal direction on the side walls of the arcade, corresponding to the location of each floor slab.

[0018] Step two: Construct the main steel frame and set up passageways in the main steel frame at the locations where the corresponding arcades pass through. After the main steel frame of each floor is completed, construct the floor slabs and balconies immediately until the main steel frame is completed.

[0020] Step four: hoist the steel roof truss.

[0021] Step 5: The glass curtain wall around the main steel frame of the construction site.

[0022] Step six: Construct the terracotta roof structure, eaves structure, and glass louvered skylight structure.

[0023] Step seven involves constructing the terracotta sunshade structure on one side of the main steel frame and the terracotta louvered curtain wall on the other side of the main steel frame. This completes the construction. Compared with existing technologies, this invention has the following characteristics and beneficial effects.

[0024] 1. The steel structure building with an internal through-archway of this invention is located at the center of the project plan. The distinctive above-ground archway opens up an effective pedestrian passage to the east and northeast corner buildings, connecting urban public spaces and revitalizing the surrounding buildings. At the same time, the steel structure building with an internal through-archway of this invention has unique local cultural characteristics. The shape of the archway echoes the shape of the traditional ceramic kiln in the region. Through the overall casting process of colored fair-faced wood-grain concrete and kiln bricks, and by adding varied glaze effects, broken bricks, fragmented bricks, and concave-convex variations to the surface of the kiln bricks, the design ideas and concepts of modern architecture are combined with the traditional architectural culture of the region to create a modern building that integrates function and local characteristics.

[0025] 2. In the steel structure building with an internal through-archway of the present invention, the alternating arrangement of terracotta roof structure and glass louvered skylight structure greatly improves the appearance and functionality of the roof system; the terracotta roof structure increases the harmony between the building and the surrounding old buildings, preserving the style of the old buildings; at the same time, the inventors have added a modern architectural feel to the roof by setting up glass louvered skylights along the entire length of the roof, giving people a visual sense of combining modern and ancient architectural styles, and the setting of glass louvered skylight structure also increases the building's lighting.

[0026] 3. The present invention features a glass louvered skylight structure that runs through the top of a steel structure building with an internal arcade. This structure greatly increases the amount of natural light inside the building compared to opening windows on the roof. At the same time, the alternating arrangement of the glass skylight system and the terracotta roof structure also enhances the appearance of the roof. In addition, the glass louvered skylight structure in the present invention uses electric louvered blinds, which improves the operation performance of opening and closing and facilitates indoor operation.

[0027] 4. This invention connects a sleeve to the side of the inclined keel, and sets an insert and a connecting rod in the terracotta tile. The terracotta tile and the sleeve are rotatably connected through the insert and the sleeve. When it is necessary to adjust the angle of the terracotta tile, simply remove the first screw, rotate the terracotta tile to the required angle, and then insert the first screw into the corresponding insertion hole and through hole. Adjustment is convenient. In addition, the terracotta tile of this application has a through hole, which greatly reduces the weight of the terracotta tile. At the same time, this invention installs an aluminum alloy insert in the through hole of the connecting rod, which enhances the strength of the terracotta tile connection part and avoids damage to the terracotta tile during repeated rotation.
