Chapter 164 Ancient temple structure, angle beam displacement value!
The next day, Lin Ran did not set off at four o'clock like yesterday. Instead, he had a rare sleep.
After all, he wasn't going to pray, so he didn't have to worry about missing the best time to pray.
All the way up the stairs, we arrived at the entrance of Gexian Temple. The young novice at the door saw Lin Ran and immediately ran in to report to the abbot.
Afterwards, the abbot went out with his disciples to greet him. He was so polite that other people who came to pray thought Lin Ran was some big shot in the temple.
Of course, Lin Ran did not stop in the main hall, but followed the abbot directly to the backyard.
In the backyard, stood a tall, bearded man with a hammer in his hand and his last name "Yang" printed on his head.
The big man is directing his workers to carry out repair work.
But it is only a small effort and we dare not start large-scale construction.
The abbot brought Lin Ran to him and introduced: "This is the best engineer nearby, his name is Yang Yu."
"Hello, Master Yang." Lin Ran stepped forward to shake hands with him.
Yang Yu also returned the greeting: "Hello, brother Lin. I heard from the abbot that you know a lot about the architecture of the Tang Dynasty. We have indeed encountered a problem. I would like to ask my brother to give me some advice!"
"Brother Yang, you're welcome. Just elaborate on the problem!" Lin Ran replied politely.
Yang Yu smiled slightly and had a better impression of Lin Ran. He originally thought that at his age, after gaining some skills, he would look at people with his nostrils, but he didn't expect that he would still be in this state of mind.
Without further delay, Yang Yu immediately took out a drawing from his briefcase and spread it out on a wooden table in front of the construction site.
"This is a rendering drawn by our architectural designer based on previous buildings, but there are always some problems."
Yang Yu pointed to the drawing and said, "If we follow the original layout, let alone an earthquake, even a slight shake will cause another collapse."
"I have to say that the wisdom of our ancestors is indeed superb! The secrets and supporting structures here are really hard for us old men to see through!"
Lin Ran took the drawing and took a look at it, and immediately admired it.
Yang Yu is worthy of being a specially invited architect, and his subordinates are also very professional. The drawings produced are almost the same as the original ones.
But he also encountered a thorny problem, which was the design of load-bearing columns.
According to the original drawings, the load-bearing columns are thicker at the top and thinner at the bottom, which actually tests the skill of the craftsmen!
Fortunately, in his previous life, Lin Ran was fortunate enough to witness the restoration work of the East Hall of Foguang Temple, and he brought a large number of advanced instruments with him at that time.
Led by Tsinghua University, a comprehensive and detailed survey of the hall was carried out using a combination of total station, three-dimensional laser scanner and manual measurement.
The accuracy of surveying and mapping results has been improved from centimeter level to millimeter level!
After a complete redrawing, the style of the early Tang Dynasty was simulated!
"It's really unimaginable that such a wooden structure can actually support this temple." Yang Yu sighed.
He can simulate building materials and craftsmanship.
However, if the design is based on the existing structure, I am afraid that the house will collapse soon!
This was also the main reason why he didn't dare to take action, so he had to let his men repair the outer wall silently, making small fuss, which was harmless.
After reading the drawings, Lin Ran couldn't help but smile, and he already had preliminary calculations in his mind.
So he shared with Yang Yu: "Gong Yang, maybe our understanding is wrong."
"How do you say this?" Yang Yu asked curiously.
"Wood structure buildings are not immovable. Unlike steel and concrete, they are subject to great changes in temperature and humidity, and will undergo slight displacement changes over time," Lin Ran explained.
Yang Yu nodded. He had also participated in the repair work of wooden houses before.
The problem raised by Lin Ran did exist, but although he could find the problem, he could not think of a solution.
How could they know how the structure had changed over the past 1000 or two hundred years?
Lin Ran took out the architectural drawings he drew, with some formulas marked on them.
Yang Yu was very curious and asked: "Brother Lin, can I borrow the drawings?"
"Excuse me." Lin Ran originally brought the drawings to share with everyone.
On the drawing, Lin Ran marked the height and width he guessed, all of which were rounded.
But he used formulas to calculate the specific location thousands of years ago.
Moreover, on the drawings, the positions of all wooden structures that may be displaced are also marked, and there are more than 70 of them!
Such a huge workload is difficult for Yang Yu to handle, and it may be difficult for his engineers to draw it for three days and three nights.
How did the boy in front of him do it?
After Yang Yu saw the drawings drawn by Lin Ran, he seemed extremely shocked!
"Brother Lin, did you infer this?"
If the drawings drawn by his men before, it may cause the house to collapse.
But the structure designed by Lin Ran can only be described as perfect.
It is definitely not a problem to last for decades, or even a hundred years!
You must know that this is a wooden house, and the mountain where they are located is very damp.
Lin Ran nodded: "Of course I don't know the specific value. You may need Yang Gong to arrange for someone to measure it. We can work out his original position together."
"Easy to say." Yang Yu was overjoyed, and most of the confusion in his heart was relieved.
Silently watching the conversation between the two, the abbot also stroked his beard, with pride on his face.
He has always wanted to show the original appearance of Gexian Temple to everyone, which was also his master's last wish.
It's a pity that I don't have a deep understanding of Tang Dynasty architecture and lack the help of experts.
Only private architecture enthusiasts are willing to help, but unfortunately their capabilities are limited.
Despite his young age, Lin Ran has unique insights into the architecture of the Tang Dynasty. He invited such experts, coupled with the meticulous work attitude of Yang Yu's engineering team.
He believes that the glory of Gexian Temple will be restored soon!
Even though he is a monk, he does not rejoice in things or feel sad about himself.
But this was his lifelong wish, and when it was about to be achieved, he couldn't hide his joy.
Yang Yu arranged for his men to measure the data of the ancient temple, and then pointed to the values on the design drawing and asked: "Brother Lin, how was this movement calculated? Can you tell me something?"
Lin Ran smiled and said: "This formula was compiled by experts who have participated in the Great Buddha Hall. As long as the temperature difference and humidity change between the inside and outside of the city are calculated, the endpoint translation of the corner beam can be calculated."
His men came over with the measured data.
Lin Ran began to show Yang Yu the calculation process: "The displacement of the northwest corner beam is 3.5 mm, and the displacement of the southeast corner beam end is 6 mm."
As he spoke, he also drew a curve on the paper.
The horizontal axis is the angle beam displacement value, and the vertical axis is the ambient temperature change.
It actually perfectly fits the curve of a linear equation of two variables, and the trend is consistent.
Yang Yu was full of praise: "I have never heard this statement for many years of studying architecture. I really learned a lot today!"
Lin Ran's statement is not without basis. On the contrary, it can be proved through mathematics. It can be said to be extremely rigorous!
This also shows that they can indeed perfectly reproduce the image of the temple!
Yang Yu was excited to be able to participate in such a project, and immediately told the workers to purchase materials, preparing to show off their talents and restore the glory of the ancient temple!
