In the southeast corner of the courtyard of the daytime studio, interviewees wore gray carpentry coats.

Unlike the strictness and nervousness of the interviewers in other places, the atmosphere here seems to be much more cheerful and relaxed.

The crowd rolled up their sleeves, holding planers and chisels in their hands, and pieces of wood were quickly processed.

There was sawdust all over the ground

Unlike the West, its history has been inseparable from wood since ancient times, intertwined with each other.

The old cow was strong, and his arms were thicker than the thighs of a thinner man. The flat head, deliberately cold face, and the dark-toned gown gave many people who came to the interview a strong sense of oppression at first.

But this sense of oppression did not last long, although Lao Niu is fiercer on the outside, but on the inside he is a really gentle person.

When he saw the work he liked in his heart, he immediately forgot about the idea of giving the newcomer a ride together the day before yesterday at a small meeting

Lao Niu stood in the middle of the crowd and glanced at the hot scene around him, and when he saw it, he only saw that the most of them were wooden seats of different shapes, and the rest were wooden lampshades and wood carvings

There is a spiral wooden ladder that climbs up the middle pillar, and there is a simple model of a wooden house

There are too many ideas, and some of them even make Lao Niu's eyes light up.

The old cow looked at it, his mouth grinned to the root of his ears, and a pair of round eyes had already narrowed into slits!

I like it so much, I like this scene so much.

This is different from the feeling of being with people during the day, and there is more of a like-minded happiness here.

Suddenly, his eyes widened as he looked at one place.

I only saw Lao Niu step in a few steps in front of the work that interested him, and Lao Niu didn't pay attention to the demeanor of his predecessors, and squatted down directly.

It's a bridge, a bridge that's completely different from an ordinary bridge.

There are two main differences:

One is the modeling, have you ever seen a bridge with a roof? It's like the roof of the house in ancient China.

The second is the structure of the force, which seems to be extraordinarily simple.

It doesn't even need a nail or a rivet, and the most basic combination unit only needs six members, of which four are longitudinal and two are transverse, and the plane is in the shape of a 'well'.

"This is a covered bridge?"

The old cow carefully observed every part of the bridge, and then raised his head to look at the young man in front of him.

The young man was also inch-haired, wearing a plain white shirt and a gray coat that had been issued to them to avoid sticking to sawdust.

The edges and corners of the young man's face are very distinct, and his eyes are not big or small, but they are extraordinarily bright.

Medium build, but very stylish!

"It's a covered bridge that has undergone secondary creation."

Without waiting for the young man to speak, the old cow followed closely and said again.

"Covered Bridge"

I saw the movement of the young man's hand pause slightly, and then the corners of his mouth raised an arc, and he whispered: "This is two thousand years old!" ”

"Can you tell us about it?"

Lao Niu asked with his two thick arms on his knees, his legs squatting, and his mouth grinning.

"The covered bridge is also known as the Hongqiao and the Centipede Bridge."

The young man glanced at the old cow and nodded, knowing that this was a test of himself.

"It refers to a covered bridge that protects the bridge and provides shade from the sun and rain, as well as for workers to rest, communicate and gather."

"Its plane is in the shape of a 'well', and the friction of the compression is used to make the members more and more tightly pressed."

"This kind of structure does not need to be riveted, only the same specification of rods, do not press interspersed and lapped."

The young man turned the model in his hand diagonally, stretched out a finger and pointed to a place, and said so.

Lao Niu is the interviewer in this area, and there are always many people who pay attention to him.

When everyone saw the old cow squatting in front of a young man, they were shocked.

Some of the interviewers who had already completed or were about to finish their work actually gathered around one after another.

"I've heard that although the bridge doesn't need to be riveted, and although it has an extremely long span and only one arch, it can bear a lot of weight."

At this time, Lao Niu pointed to the bottom of the model bridge, only to see that this wooden bridge with an extremely long span has only one 'eight-figure structure' formed by the vertical and horizontal splicing of round wooden strips.

From the point of view of common sense, such a span bridge must have at least three to five arches or columns to be heavy, otherwise the weight it can withstand is absolutely worrying!

"Excuse me, is that so?"

Lao Niu's bull's eyes were completely open, and he looked straight at the young man in front of him and asked.

"Of course, the covered bridge is completely dependent on its own strength, friction and diameter, the angle, the horizontal distance, etc., and the structure is simple, but it is exceptionally strong!"

"Just my bridge model"

The young man's expression was not too large, he glanced at Lao Niu and the people surrounding Lao Niu, and said, "If you are afraid to stand up, there will be no problem with the three or five of you!" ”

The young man's voice fell, and the audience was in an uproar.

The interviewers looked at the wooden model of the bridge in front of him, which was about a meter long and more than 30 centimeters high, and their faces showed disbelief at the same time.

"How is that possible? The span of this bridge is so large, it is impossible for the stressed structure to be satisfied! ”

Behind him, someone immediately opened his mouth to retort.

It's really too exaggerated, three or five people have at least three or five hundred pounds, how can such a small wooden model and a model with such a long span be able to withstand it?

"That's it, that's it! The cowhide is blowing up."

"Let's go back and have a good look at structural mechanics, and dare to come to the interview in the daytime studio at such a level!"

"It's a joke."

All of a sudden, the laughter erupted.

In the crowd of onlookers, Lao Niu watched with interest without squeaking, and on the other side, there was also a person at the back of the onlookers who remained silent.

"Gui Huahao?"

It was an ordinary-looking girl, and the girl's eyes looked at the two people who were surrounded in the middle, but her mouth was a little suspicious.

'Smack! ’

In the face of these doubts and ridicules, the young man did not refute or explain.

I saw him grasp the bridge model with his right hand, temporarily dismantle the roof, and then put it hard in front of everyone.

He didn't speak, but his posture and movements were clearly revealed.

'It's a mule or a horse, let's pull it out and slip it.' ’

'Too lazy to talk nonsense with you, you step on it and take a look!' ’

This is undoubtedly what youth means.

"You go up and try it."

At this time, Lao Niu also spoke.

Lao Niu's words sounded, and several people immediately rushed in.

With sarcasm on their faces, they cautiously stepped on the deck of the bridge.

At the same time, everyone held their breath.

They looked at the toy-like model of the bridge, and they didn't dare to breathe, as if the bridge would be crushed in the next second.

But things are clearly not as they thought.

Alone

Two people

Three people

Three people stood up one after another, but the bridge was still steady, and there was no sign of collapse.

At this time, the crowd of onlookers suddenly sank, their eyes widened, and there was disbelief in their eyes.

The three people standing on the bridge were even more embarrassed.

"Go ahead."

The old cow smiled and opened his mouth again.

Four people

Five people

Six people

In the blink of an eye, there were already six people standing on the bridge deck, even more than the 'three or five people' at the beginning, but the bridge was still as stable as Mount Tai.

"It's really Gui Huahao!"

The onlookers had already covered their mouths and exclaimed.

At the same time, the girl made a statement.

"Go on!"

The smile on Lao Niu's face became thicker and thicker, and he said loudly.

On the deck of the model bridge, from the bridge head to the bridge position, it is already full of people, but at this time, this wooden bridge, without a nail or rivet, only a wooden bridge with a figure-eight arch is still stable!

Everyone has long since fallen silent.

The old cow and the young man stood up at some point, facing the bridge model.

"From the mechanical analysis, the upper longitudinal beam is pressed on the beam, and the beam is pressed on the opposite longitudinal beam, and the upper and lower longitudinal beams clamp a beam, and the friction force makes the beam unable to slide, and the structure is simple and wonderful."

Seeing this, the corners of the young man's mouth raised slightly, and a crisp voice sounded:

"This kind of structure, the whole is an arched structure, so it is compressed along the center of the arch as a whole, and there is no bending moment, and it is the simplest simply supported beam for each member, which bears two kinds of concentrated loads."

"As long as the two ends are fixed, the bridge can bear the downward load well, due to the special structure, the bridge is subject to the upward rebound force, it is easy to lose stability and be damaged, for this reason, the 'centipede bridge' are formed by the use of a covered bridge, the bridge corridor is not a burden, but increases the stability."

"In ancient times, whenever there was a flash flood, the local residents would move the heaviest objects or large stones in their homes to the bridge to increase the stability of the bridge."

In the face of the explanation, some people were stunned, but more people became more and more confused, and there was an unclear expression on their faces.

'Smack! Syllable! Syllable! ’

Lao Niu's applause was particularly loud.

"Mr. Gui Huahao, I formally invite you to join my team."

Lao Niu stretched out his broad palm and said seriously.

"It's my pleasure."

Holding hands, the young man replied with a smile.

"Gui Huahao? Gui Huahao! ”

"It's him!"

Someone whispered, and suddenly exclaimed: "It's him, no wonder!" ”

"It's the demon of Xi'an Jianzhu University who chose to be an architect because his grandfather is an art master, his father is a sculptor!"

"Didn't we put our faces over and let them beat them?"

One said with a wry smile
