How did the Shanghai elderly reproduce more than 7,000 mortise and tenon parts in Zhao Zhouqiao with 200,000 processes?

He once created a miniature model of the Temple of Heaven's Hall of Prayer with full tenon and mortise skills, and won the gold medal at the 20 16 World Handicraft Expo. Every door and window can be opened and closed freely, and all 877 parts are spliced with tenons and mortises without a drop of glue. Every combination of tenons and mortises conveys the ancient culture and wisdom of China. The netizen sighed with emotion, "Even if the technology is developed again, the tenon of pure wood structure is still full of wisdom and charm."

Have you met Rubinso? Legend has it that in the Spring and Autumn Period, Lu's craftsman Lu Ban made a spell out of six pieces of wood to test his son's cleverness-a detachable toy, told him to take it apart-after a busy night, he finally took it apart-this toy was later called Lu Ban Suo-in fact, this is just a legend. Lu Ban Suo is also called Kong Mingsuo, Bie SAP, Liu Zilian Boat, Mo Zuo, Difficult Wood, etc.-originated from China.

Speaking of tenon-mortise structure, an old engineer made a model of the Temple of Heaven with tenon-mortise structure in Shanghai! He is a craftsman and more stubborn. This miniature Hall of Prayer for the New Year took five years and went through 100,000 procedures. It consists of 765,438+008 parts. The smallest part is only 2mm, without a nail or a drop of glue, and it has a complete mortise-and-tenon structure.

The height is 0.5m, and the maximum diameter is less than 0.8m, which is 0/times higher than the original scale of small 8/kloc! Every component can be disassembled and built like a real house according to mechanical principles. Every small door can be opened with a gentle push; The double eaves of the three-story building spiral up and gradually close, exactly like the original shape; Touch it with your fingers, the steps are smooth and smooth, the doors and windows are concave and convex, and every place is full of royal texture!

As a new technology, 3D printing technology uses adhesive materials to construct objects by printing layer by layer. 3D printing of concrete is a new additive manufacturing technology which stacks cement-based composite materials layer by layer. Because of its advantages of modeless, automation, rapidity and flexibility, 3D printing of concrete is rapidly emerging in the fields of architecture, bridges and infrastructure.
