Record Broken – Expo’s Grand Ring is the largest wooden structure in the world

Less than a month before the launch of the international exhibition in Osaka, Japan (is scheduled to open on April 13), the crews are working with time to finish the touches on dozens of complex wings-many of which were designed using local Japanese rice-including the host country wing, which surrounds layers and layers of crossed rays around the wheat ring. “

Designed by Nikken Sekkei and inspired by the topic Between lives“The Japanese Wing allows visitors to experience a” individual cycle “without start or end”, ” Nindo saidWith all the wood in the standard construction to be dismantled and replaced after the exhibition.

It consists of 560 cross -wood panels, all of which are placed together in the formation of a giant ring. Through cross wood, “It symbolizes transformations between life situations.”

This comes as a disturbing approach that comes out of Osaka that reveals that only eight out of 47 wings of the country-including Ireland, the Philippines, South Korea, Australia, Bulgaria, the Netherlands, Malaysia and Hungary-were approved by its consequences in the Japanese Association of the World Exhibition for the year 2025, with the costs of RISK materials, the complex design for some reason it causes.

“It is true that there is a risk that the construction (from the wings) is not completed in a timely manner to open the exhibition,” said Hiroyuki Ishig, the Secretary -General of the exhibition, who pledged to provide all necessary assistance to accelerate the construction to meet the new final dates.

Fears about the delay come after the total construction costs of the “integrated exhibition” increased to 235 billion yen ($ 1.6 billion), with the division of the conservative, municipal and private bill. The most prominent in the exhibition – half the size of the 1970 exhibition with the number of participants ’weakness – is the giant ring, which was recognized earlier this month by Guinness World Records for being the largest wooden architectural structure in the world, which will host all the wings inside its walls.

Inside the episode, the wings, which have a large-scale feature, are unique on their way-the Swiss wings are the lighter wing ever, the Czech wing, known as bohemian glass, is a glass spiral, while the Austrian wing is a form of a 12-meter-high timber. Then, there is the Sumitomo Forestry Corporaate wing, which uses cypress and rice trees on the roof and walls of it, They all come from the company’s forests, which were planted for several years.

According to Kengo Kuma, the legendary Japanese architect responsible for the Malaysia wing inspired by bamboo-one of the few approved-and the 2025 exhibition is columns for 1970: “At that time, there was a feeling of the age card, with the idea of ​​building more and more.” Kuma said while visiting the site. “This time, the use of warm natural materials gives the entire place a feeling of trying to live happily in a time of low enthusiasm (for growth). Another is a strong awareness of 3RS – reducing, recycling and recycling – to enhance sustainability.

Last month, Wood Central spoke to Andrew Dunn, The Australian study tour that will take dozens of architects, engineers and construction professionals around the exhibition wing in early May.

“From the Tokyo Olympics and the exhibition, what we see comes out of Japan is great,” said Mr. Dan, who will tour the oldest wooden building in the world. “However, highlighting, without a question, is the two days in the exhibition, where we will explore the major episode (one of the largest wooden structures in the world that has ever created).”
