Not surprisingly, the twin towers of the Dragon Mountain International Business District in Seoul, South Korea, which is called "Dragon Dance", are truly extraordinary. They are covered with scales, just like real dragons. The scale-like skin of a dragon dance can in fact breathe: the main effect of gaps between overlapping panels is similar to the 600 mm ventilation holes through which air can circulate, allowing them to breathe like some animals. The Dragon Tower will have a double top floor that will shine in plenty of natural light. At the same time, the audience can take a 360-degree view of downtown Seoul and the nearby Han River landscape. May 14, Beijing time When the makers of Dubai's iconic "Sail" hotel unveiled a new tower, you may be pretty sure that it will never be just a rectangular building that you can forget about. Not surprisingly, the twin towers of the Longshan International Business District in Seoul, which is towering into the clouds and named "Dragon Dance", are truly extraordinary. They are dressed in "scales" and are as impressive as real dragons. Even more incredible is that these glass scales can actually "breathe." These buildings are used for both commercial and residential purposes and are composed of small, pointed towers with cantilevered central sections. These towers feature a series of eye-catching diagonal cuts that create space for activities that float outside the dragon's twin towers. The skin of a dragon dance like a scale can in fact breathe: the main effect of the gap between overlapping panels is similar to the 600 mm ventilation holes through which air can circulate, making them breathe like animals. The twin towers also have high-tech features such as radiant heating and fuel cell waste heat power generation facilities on the basement floor. The heat recovery technology through electric centrifugal chillers, daylight-sensing lighting control, and photovoltaic solar panels on the top of the tower are the highlights of the Dragon Tower. Architects Adrian Smith and Gordon Gill, who created the Dragon Tower, said that their design was inspired by traditional Korean pagodas. The Dragon Tower consists of a 1,500 foot (about 450 meters) high Tower 1 and a 1300 foot (about 390 meters) high Tower. These two parts are not exactly the same. On the 88th floor of Tower 1, the dense incisions at the top and bottom of the tower are V-shaped. But on the 77th floor of the 2 towers, these incisions move diagonally along a continuous line; they are also arranged radially in the center. Visitors can see the unpredictable trajectories of these incisions as they move around the tower. Adrian Smith, a member of the American Institute of Architects and a member of the Royal Institute of British Architects, said: "There is a mutual complementary relationship between the two bodies of the incision layer as if they were dancing. The important thing for our design is that Reflecting and explaining the rich cultural connotations of the Dragon Tower, although this tower is abstract and contains many high-tech factors, it expresses this meaning vividly.We try to design with a beautiful and architectural style. Dance Dragon Twin Towers. I believe this is an outstanding example." In both buildings, the top and bottom tower cuts are covered with glass, so that the sky pane on the topmost structure is visible to the outside so that the bottom floor structure forms a transparent floor. At the same time, it also creates conditions for the audience to appreciate the city center of Seoul and the landscape adjacent to the Han River from a 360-degree perspective on the top floor of the duplex. In addition, this structure can also allow sufficient natural light to come in. According to Gordon Gill, member of the American Institute of Architects, “The abstract memories of historical buildings give the dragon a unique perspective from the ground to the sky, creating a unique internal experience. Integrated ventilation windows and self-shielding cantilevers form the The twin skins of the twin towers."(Xiaowen) Flap Wheel Machine Mounted wheel machine is for producing flap wheel with shaft,which can slice abrasive clothes and place small pieces automatically. more effecient than arranging the flaps manually.
