The old man glanced at Huang Lei, smiled, then thought for a moment and said, "Mortise and tenon joints are the crystallization of the wisdom of ancient Chinese craftsmen."
"The protruding part is called a tenon, also called a tenon, and the recessed part is called a mortise, also called a mortise or tenon groove."
"It originated in the Hemudu period about 7,000 years ago."
"It can be roughly divided into three major types."
"One type is mainly the joint between surfaces, it can also be the joining of two edges, or the intersection of surfaces and edges. The other type is the structural method as a point. It is mainly used as a T-shaped combination of horizontal and vertical timbers to form
Angular joints, cross joints and extended joints of straight and curved timbers, and another type of construction method that combines three members together and connects them to each other.”
"But the mortise and tenon structure has relatively high requirements on wood."
"If it is wood such as plywood, it is difficult to use it as a material for mortise and tenon structures because it is easy to crack."
Ling Rui nodded after listening to the old man's words, "Yeah."
"But because of this, the mortise and tenon joints of the log structure are extremely earthquake-resistant. Forbidden City experts and an American carpenter copied a model of the Forbidden City at a 1:5 ratio and conducted earthquake simulation tests. When the magnitude reached 9.5
At this time, although the model shook, it still stood upright."
"So, over the past 600 years, the Forbidden City has endured snow, frost, and more than 200 earthquakes, but it has still remained intact."
"It's really great!"
"I see."
"Oh, that's awesome!"
"But, why is the mortise and tenon structure of logs strong in earthquake resistance?" Wang Zulan looked at the old man curiously.
"Which structure does this have to do with?" The old man smiled, then looked at Ling Rui, "Why don't you ask this little brother for advice?"
Ling Rui raised his eyes, wondering what the old master was playing with, so he said, "The brackets can evenly distribute the weight of the eaves on each beam and column, which can make the house balanced and stable, and the earthquake resistance will naturally be improved."
At this time, Ling Rui also put down the tools in his hands, assembled another set of Luban locks, and handed them to Peng Peng.
Peng Peng took it and looked up and down, left and right, "Brother Rui, is this the same as the previous one?"
"Yeah." Ling Rui nodded, "Yeah, what's wrong?"
"But... how to unravel this?" Peng Peng was helpless, because Ling Rui said not to search online, so for now, no one present has been able to unravel it.
"Isn't this a question left for you?" Ling Rui asked, "There are several models now. You can try it yourself. Come on, we believe you can do it."
Peng Peng:...It's so difficult for me.
…
"Hahaha!"
"Poor Pumbaa."
"It's actually very simple! It's a pity that they can't see us talking!"
…
Ling Rui smiled and continued his work. Carpentry is a magical thing. In other words, some hands-on skills are magical and give people a strong sense of accomplishment.
"Tear this down, trust me!" Chi Chi said to Peng Peng.
Peng Peng rolled his eyes, "I believe you."
The three girls each took one and were taking it apart, but there was no progress.
The people next to me looked worried.
"It's so difficult!" Xie Na was a little anxious, "I think...how could this be a child's toy?"
"It's not just a child's toy."
"It's really difficult." The baby was also a little discouraged.
Zifeng silently continued to take it apart. Suddenly, he pulled out one of the sticks and said, "I took it out!"
Everyone looked at Zifeng, and sure enough, the Luban Suo on Zifeng's side had been loosened.
"Sister...can you fight back?"
Zifeng:……
"Why should I fight it back together? I finally took it apart!" Zifeng glared at Peng Peng, which wasted all his efforts!
"That makes sense."
"Hahaha!"
Chi Chi looked at her "niece" and couldn't help but smile. Sure enough, she looked so cute.
After more than an hour, Ling Rui stopped because he had already done so many sets and he felt a little tired.
Others also had sweat on their foreheads.
"Take a rest." Ling Rui said, "Take your time, don't be in a hurry."
"Come on, come on, drink some water." He Jiong brought out the freshly warmed milk, "to replenish your strength."
"I'm sleepy." Chichi yawned and took the milk. Speaking of which, they came here early in the morning and haven't taken a nap yet.
"It's half past three now. Let's go get some sleep." Ling Rui thought for a while and said, "Especially the girls."
"Why especially girls?" Wang Zulan looked in disbelief, "We also need to get some beauty sleep, okay?"
Ling Rui laughed and nodded, "Okay."
"Hey, I don't need to take a beauty nap, I take an afternoon nap." Chi Chi said in disgust.
"Yeah, what the hell is beauty sleep?" Zheng Kai was also helpless.
"Zu Lan, ignore them, let's go and get some beauty sleep!" the baby laughed and spoke.
"Go, go, go!"
"Dinner." Deng Chao thought for a while and said, "Do you need our help?"
Ling Rui thought for a while and said, "It shouldn't be needed."
"Okay, then I'll sleep until dinner." Deng Chao said with a smile.
other people:……
"Go ahead, go ahead." Ling Rui waved his hand.
"Xiao Rui, aren't you going to sleep?" He Jiong asked after dividing the milk and looked at Ling Rui.
"I'll take a nap for a while, but I need to think about how to cook dinner." Ling Rui looked helplessly at the men's team, "These seniors ordered dishes that are difficult to cook."
"Twenty-Four Bridges on a Moonlit Night."
"Beggar's Chicken."
“Good soup.”
"Burned cabbage."
"Who can listen to the jade flute and Luomei."
"Five dishes, six people came, who of you didn't order?"
Zheng Kai stood up at this moment, "I didn't order! These people have forgotten me!"
"Then stop it." Ling Rui said again.
Zheng Kai:......???
"Why?"
"Because your dish must be the Five Treasures of Yuanyang!"
Zheng Kai was silent for a moment, "How did you know?"
"The Chinese sturgeon rewarded by the program team...I guess it won't be steamed and eaten." Ling Rui sighed, "It will definitely cause trouble. Besides, you have to record for three days, so you can't eat all the dishes in one day.
Is it over?"
"So, I will probably only cook two of the dishes you ordered tonight."
Chen Kezhou picked up the speaker and said, "Xiao Rui's answer is correct. As for which two to choose, you can decide for yourself."
"Whoever heard about Jade Di stopped making Luomei. The program team hasn't even given them the ingredients yet."
"Let's have twenty-four bridges under the moonlight and roasted cabbage tonight."
"It will be all right!"
"Okay!"
"So which five delicacies are the five delicacies of the mandarin duck?" Chen Kezhou looked at Ling Rui and asked helplessly, "I don't know much about it, so I can't prepare the ingredients. But I really want to restore this dish.
.”
Ling Rui frowned slightly, "Let me think about it and get back to you before going to bed tonight."
"OK."
"Um, I've already brought the ham." Deng Chao said hehey.
