In Ye Qing's hand, he held a round piece of synthetic light steel, which was analyzed by the local magnification function of the glasses and the number of materials. Ye Qing could clearly see the round light steel, which was surrounded by a layer of grayish-brown coarse particles from the fracture.

The surface of the light steel originally had a layer of black anti-rust paint, and now the anti-rust paint is neatly peeling off. In Ye Qing's field of vision, these coarse particles are composed of countless tiny cracks.

This is the most intuitive expression of metal fatigue, its internal structure has been destroyed by external forces, and its strength has been severely reduced.

The causes of metal fatigue are caused by repeated pressure from external forces. Many countries have had a series of regrettable aviation crashes caused by metal fatigue.

A piece of metal placed there will not be damaged without external force.

The light steel structure bracket of the canopy is stationary, and the bulb cables will not move.

Then the only moving parts that can occur are the water circulation cold air conditioner.

At intervals in the water circulation air conditioner, an extension is fixed at the top, and the extraction motor inside is buzzing and rotating at high speed.

"It should be the exhaust motor in the air conditioning extension, which caused the metal resonance of the bracket supporting the pipe and the external unit, and the bracket quickly fatigued. "Ye Qing's current glasses are transparent glass, and outsiders can't see anything abnormal.

"How do you judge?" Chief Designer Xiao Jun looked at Ye Qing with some nervousness.

"It's easy to prove it. Ye Qing took off his glasses, pointed to another exhibition hall passage and said, "The consistency of industrial products is very high. You can check that those pipe supports that have not fallen off, if the strength of those connections is also significantly reduced, it proves that the resonance must be caused by the operation of the motor. ”

"Very likely!" The representative manager of Deli Group was stunned for a moment, and then slapped his thigh: "Since there is no problem with our design, then resonance is the most suspected cause of the accident." ”

Several effective air conditioner maintenance personnel hurriedly ran under the intact extension next to them with scaffolding. Skillfully dismantle the extension, and then cut off two light steel structures connecting the extension and the pipeline.

Without the need for instruments, just by clamping the round light steel with pliers and doing a bending test, it can be very obvious that these two round light steels are extremely weak.

"It's really resonant. The representative manager said anxiously: "No, our motor products are absolutely qualified, and the concentricity of the bearing is much higher than the national standard, so there is no abnormal vibration at all." ”

"It's not an abnormal vibration, it's a natural vibration of the motor. Ye Qing explained to a group of people with confused faces: "If the motor vibrates abnormally, you can judge it by listening to the sound. ”

"But when the motor is running and the fan is spinning, there is a noticeable natural vibration. ”

"In layman's terms, it is normal vibration, the sound is soft, and the amplitude of the vibration is very small. However, there will still be high-frequency vibrations, and if this vibration frequency is close to the resonance frequency of the external fixing material, it will resonate. ”

"Obviously, the resonance flatness of these light steel structures is very close to the natural vibration frequency of the motor, and the metal fatigue of the severe zhòng will occur. ”

"I don't know if you've seen the movie Grim Reaper, there is a scene in it, which talks about the resonance between the air conditioning extension and the connection, and the entire air conditioning extension fell down. ”

"I see. The representative manager suddenly became enlightened: "This is a coincidence, a big coincidence." Our products are also tested for resonance, but natural vibrations cannot be eliminated. I didn't expect it to resonate with this light steel material. ”

"Simple~"

"It's very easy to solve, we just need to adjust the speed of the motor to avoid resonance. ”

"What about these scaffold structures that have been damaged?" Xiao Jun, the chief designer, was full of resentment and made many staff members who stood in various exhibition areas to watch the excitement and immediately fled in fright.

Oh, yes~

There is already a corner of the pipe and extension falling, which means that at this time, all the air conditioning extensions in the exhibition hall may fall.

With this kind of chance, who would dare to risk their own lives?

"The exhibition area was temporarily closed, and all the staff left, and they entered the venue after the hidden dangers were solved. The district magistrate Wen Xiaowei immediately issued an order, as long as there were no casualties, there was still room for redemption.

Without any hesitation, the crowd ran out.

Some seem to have walked from spring to summer, and the canopy has a certain heat preservation function, and the cool air inside has not completely dissipated.

At this moment, they all suddenly ran outside the canopy, and suddenly felt so hot.

"Thank you, thank you so much for your solution, you have saved us a lot of valuable time. Standing outside the canopy, the district chief Wen Xiaowei's nervous expression eased a lot, and he held Ye Qing's hands and kept shaking.

"Where is your showroom? If the showroom can be restored, I'll ask the staff to advertise your company on the giant screen projection TV. ”

"No. 42 in Zone Z is the giant beast heavy industry in the innermost corner. Ye Qing scratched his head a little embarrassed and reported the location of his company's exhibition area.

That's the corner of the last row, and there's no worse place than that.

"Behemoth Heavy Industry!" District Mayor Wen Xiaowei gave a thumbs up and praised: "A very bold name." ”

"Young man, you must be mechanical, and very proficient. Xiao Jun, the chief designer, also stepped forward to express his appreciation: "When we do architectural design, we will also consider the resonance test of wind power, and the Tacoma Narrows Bridge in the United States is the most tragic example." ”

"But it's indoors, a stationary thing, and who's going to spend a lot of money on a resonance test?"

"Even if I did, I couldn't measure it. Before, we were all passing the buck to each other, thinking that the weight was overrun due to the icing. ”

"Unexpectedly, the problem appeared on the motor resonance. Chief designer Xiao Jun said with some guilt: "This is completely a knowledge ...... two fields"

"Let's not talk about that. The district magistrate heard Xiao Wei speak: "The strictness of the matter must be understood by everyone. Since there was already a problem with the bracket structure of the canopy, we had to hurry up and solve it within a day. ”

"Otherwise, tomorrow at nine o'clock in the morning, the exhibition will not be held, and our people will be disgraced. ”

"Mr. Xiao, you are a well-known designer in China, and this canopy is from your studio, you can help give ideas. ”

Chief designer Xiao Jun nodded solemnly, falling into heavy thought, during which he walked back and forth, and made a few phone calls to ask the manufacturer responsible for the production of this batch of light steel materials if there was any inventory.

After the phone call, he asked his accompanying assistant to go in and test the strength of the main structure of the canopy in a simple way.

When the information was transmitted back one by one, the forehead of the chief designer Xiao Jun was slowly covered with beads of sweat.

Walking back and forth, pinching his eyebrows from time to time to think, he suddenly realized, and then shook his head in disappointment.

In the end, the chief designer Xiao Jun was ashamed and said: "There is no other way, this batch of light steel is a specially customized non-standard product." I just asked the manufacturer. They don't have a lot of stock, not even enough to repair the collapsed in the corner. ”

"In fact, even if there is enough inventory, there is no hurry, these light steel structure construction teams entered the site a month in advance, and then welded and assembled. ”

"At this point, there is only one way. ”

"What way?" the district chief Wen Xiaowei wiped the beads of sweat from his forehead and asked nervously.

"The main structure of the canopy is intact, and where the corner collapsed, we directly took the plastic plate and pasted it, and the air conditioner that fell down was not installed. ”

"The damaged exhibit area also needs to be repaired immediately. ”

"Then ......," Xiao Jun, the chief designer, said sadly: "Under all the air conditioning extensions, the steel pipes are erected, and the weight of the air conditioning units and pipes is supported by brackets. ”

"About 300 steel pipes, there's no time. The steel pipe should be thick enough to support the weight of the air conditioner and the bracket. ”

"Bang~", the district magistrate Wen Xiaowei next to an official, the crystal teacup in his hand was not held steady, and he fell to the ground by mistake.

He is the director of the Expo Park, and when he hears about the solution of this leading designer in China, he feels that he will not have to go out in the future, and he will be laughed at by everyone.

In an international large-scale exhibition, in the exhibition hall of good guys, all the enterprise display areas, and in the center of several main aisles, there were 300 steel pipes horizontally.

How does this make people go, and how does this make companies present their products?

What about walking in an S-shape around the pillar?

What do those domestic and foreign journalists, and managers of a large group of foreign companies, think when they see this?

What if there are a few more girls who play performance art and pole dance with a pillar in order to mock this exhibition?

The Expo Park is an internationally renowned park, and the director of the park has naturally seen many young men and women with strange thinking, making eye-catching performance art in the park.

"Mr. Xiao, ...... you" The district chief Wen Xiaowei was really anxious at this time, and even changed his title: "You can think of a way again, please." If it is really a pillar, then this exhibition ......"

Chief designer Xiao Jun shook his head weakly, the design of the canopy this time was from their studio, if there was a way, why didn't he want to save the reputation of the studio?

"We ...... It can only be used as a support for the steel pipe, which is used as a fuss. Chief designer Xiao Jun wiped the beads of sweat from his face tremblingly, and said in frustration: "Steel pipes must be had, we are willing to be laughed at, and we can't let guests face the risk of being smashed at any time." ”

"Three hundred steel pipes, no less. Perhaps there are places where the steel pipes can be placed a little more cleverly. For example, in the aisle, we can use a steel pipe in the shape of a door to make room for the aisle. ”

"To make a door-shaped steel pipe, we don't know if we can be in a hurry in time......"

"Then find an art studio to do some decorations, or latte art......"

"I ...... Tell me about the mayor. The district chief Wen Xiaowei took a deep breath and walked to the side to make a call.

Five minutes later, District Chief Wen Xiaowei walked over slowly, his face a little pale.

"Let's take action, Mr. Xiao, you are responsible for the location design of the steel pipe, so as not to obstruct pedestrians and the display activities of various companies. ”

"I contacted the park department and asked them to activate the machine shop and start processing the steel pipes immediately. ”

"By the way, what is the height and diameter of the steel pipe?"

"The height is two meters, the diameter is about eight centimeters, and the wall thickness is eight millimeters, so that a flat surface should be welded at the top to support the road, and the bottom should be fixed ......"

"The time is too short, and the bottom fixing is estimated to be only able to weld the flat plate, and then punch the four corners to install the nut. ”

The district mayor Wen Xiaowei's face turned pale again, this kind of design made him feel like he was inspecting the construction site of the community in the jurisdiction.

He was about to nod his head in agreement, but his eyes inadvertently glanced at Ye Qing, who was watching the excitement nearby.

"Mr. Ye, Mr. Ye. The district magistrate Wen Xiaowei hurriedly greeted Ye Qing and walked up to Ye Qing: "Mr. Ye, you are engaged in heavy industry machinery manufacturing, do you think there is any way to make the support column more beautiful?"

"At least...... Instead of welding the platform at the bottom, fix it with a nut. ”

"In one day, it can only be processed in sections, the base is made of a hollow steel pipe, the steel pipe is sealed and welded with a steel sheet at one end, and the hole is punched in it and fixed on the ground with a nut, and finally welded with the support steel pipe above. ”

"Anyway, the steel pipe has to be decorated, and no one will see the weld. ”

"Well...... Ye Qing thought for a while and said, "The steel pipe can be DN80 galvanized pipe, and the thickness and diameter are in line with the requirements. This kind of steel pipe is very common in the market, and it is also very convenient to process. Several processing plants process at the same time, and it is easy to make a quantity of 300 pieces. ”

So far, even if the district mayor Wen Xiaowei is extremely reluctant, he can only use the chief designer Xiao Jun's construction.

Yes, what is enough time in a day?

There's no way, contact those well-known art studios and make art decorations for the steel pipes.

It's better to let people see jokes than accidents, and the exhibition can be held smoothly.

"Mr. Ye, your smashed equipment, we will compensate after the exhibition. Please forgive me, we are really overwhelmed and don't have time right now. ”

"Understand, as a company participating in the exhibition, of course, we must cooperate with the holding of this exhibition. ”

Finalizing the solution, District Mayor Wen Xiaowei and Chief Designer Xiao Jun immediately set off to get busy.

The people who watched the lively business also dispersed, and it was almost noon, the weather was getting hotter and hotter, and it was like a sauna here.

Ye Qing also walked out, and it was almost lunch time, Ye Qing was going to take Xu Xiaohu and them out for a good meal, and they would be rewarded.

Walking out of the huge exhibition hall, Ye Qing took out a three-dimensional camera from the car and took a picture of the huge exhibition hall.

The exterior of the pavilion is modern and artistic, with a design by world-renowned architects. Take a three-dimensional drawing of it, and you can make a small mini pavilion by yourself when you go back and use it as an office.

There is still some time before lunch, and Ye Qing's photo suddenly can't stop like a photography enthusiast.

Because there are many strange buildings in the Expo Park.

Even the greenery, the various landscape trees, are works of art that have been carefully pruned by master gardeners.

For example, the tree in front of Ye Qing's eyes, the Yellow Mountain Welcome Pine entrenched on the rockery, is as if it was born out of a broken stone, with entrenched roots and whiskers, green and upright.

A 3D camera can take pictures of any object and create perfect 3D drawings in an instant. After photographing several buildings, Ye Qing locked the focus of the three-dimensional camera on this welcoming pine.

The metal melting center has a three-dimensional forging function, whether it is a hull or other more complex irregular shapes, as long as there are drawings, it can be smelted very quickly.

These landscape trees have unique shapes, and if a few of them are made in the smelting center and placed in their own factories, they will definitely be very, very forced.

Anhui Province folk have a well-known all over the world, with a history of more than 300 years of wonderful arts and crafts.

Iron Painting!

Paint with a hammer as a pen and iron as ink.

In the Anhui Hall of the Huaxia Auditorium, there is a huge iron painting "Welcome Pine". Countless foreign dignitaries have taken group photos in front of this iron picture, which also makes the welcome pine a symbol of friendship between China and Ping.

But!

Who has ever seen a pure metal welcome pine made of titanium alloy?

Ye Qing wants to ask the world, who has seen it?

I haven't seen it, but there is one in the factory of Monster Heavy Industries.

Ye Qing happily pressed the shutter, and then a perfect 3D Welcome Song drawing appeared in the 3D camera's infinite drawing memory card.

Then, after taking a picture of the welcome pine, Ye Qing instantly froze his figure.

It's like being struck by the lightning of the Nine Heavens.

The welcoming pine in front of him suddenly made Ye Qing think of a very, very important question.

If......

What if a welcome pine, made entirely of metal, could be used as the pillar of the air-conditioning ducts in the exhibition hall?

What is this concept?

The core purpose of the International Science and Technology Exhibition is scientific and technological innovation, and science and technology change life.

Take a look at the structure of the entire exhibition hall, from air conditioning, to the canopy, to the light steel structure support, all of which revolve around the theme of scientific and technological innovation.

If you replace the rotten street poles that serve as pole dancing pillars, they are all idle. In the form of this amazing industrial technology that no one has ever heard of or seen.

Hasn't that become the biggest highlight, the biggest hot spot and selling point of this exhibition?

According to the plan, 300 tattered steel pillars are needed, maybe there will be some ribbons and latte flowers hanging on them, and the peace festival will be arranged like a wedding room to cover up the steel pillars of the laughing dead.

What about welcome pine, podocarpus, and crape myrtle trees, which are valuable landscape trees with strong ornamental value?

A tree has umbrella-like forks that can become fulcrums to support those air conditioning ducts.

If properly designed, a tree can replace dozens, if not more, steel pipes to complete the support work, and the placement is more arbitrary, and it can be placed wherever you want.

Imagine that when people enter the showroom, the first thing they see is not the welcome words, nor the small advertisements of the companies.

Rather, it is a striking landscape tree that is ingenious and purely made of steel.

Isn't this a combination of technology and art?

Doesn't this carry forward the traditional culture of our country and make foreigners stunned and completely dumbfounded?

If aluminum alloy is used to build the branches of the tree, then these heat conduction properties are far better than the dense branches of iron, and can also fully absorb the cold air discharged by the air conditioner and conduct it to the entire tree.

In the increasingly hot summer, what kind of cool experience will it be to walk under this kind of tree?
