It is a unique bridge-building technology in China. It is named after the rainbow resembling the sky. The biggest feature of Hongqiao is that it does not need bridge pillars, does not need nails, but is composed of shorter wood, which crosses into a circular shape. The ingenious structural design utilizes the average load-bearing load on the top to share the downward and outward loads, making the load-bearing structure of the Hongqiao very stable. https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_3067dd35-7b8e-446d-8885-729ffac0a389.jpg The structure of Hongqiao is simple, but there are quite a few mysteries. Want to know more about the Hongqiao secrets that prevailed during the Ming and Qing Dynasties? Mr. Sai takes you back to the past to witness the wisdom of science. https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_4cf63a54-868b-4bc8-a445-237c16db2798.JPG ●The principle of Hongqiao Li Chun, a Chinese artisan who was about 1400 years ago, invented a single-hole arch bridge with an "open shoulder" "Zhaozhou Anji Bridge", which can use the openings between the beams to pile up each other. The weight is transmitted to both sides. Hongqiao has two advantages: 1. When the length of the beam is longer, the arc of the arch is smaller, and the easier it is for people to pass the car. The "Hongqiao" is no longer a semi-circular, short arch bridge with a long slope! 2. In addition, the longer the beam is, the longer the river can be spanned by the entire bridge, and the more powerful it is. In the Northern Song Dynasty, the bridge-building technology was quite sophisticated. In Zhujing (Kaifeng, Henan), a lot of arch bridges were built. The painter Zhang Zairui used the realistic style to complete the masterpiece of the Qingming River. We can see that the structure of the bridge is made up of two sets of wooden beams. We will try to see the use of chopsticks and belts to build an elegant Hongqiao with the wisdom of the old ancestors! https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_f2400a2a-f63e-49e4-a62f-62e7997007cc.jpg Product specifications: ► Content: Square strip x20 / cylindrical x8 ► Material: Wood ► Origin: Taiwan
