The magic of reinforced concrete can be seen.

Wang Chen once watched a special video on the history of world architecture, which introduced why a single large-scale building was not built in ancient times, and the foundation of a single large-scale building is that there are good load-bearing materials that can carry the overall weight of a large building. In ancient China, the main materials of construction were wood and stone, which could not meet the load-bearing requirements of a single large-scale building.

It was not until the 19th century that steel and concrete began to be gradually applied to building materials, and single large-scale buildings began to appear. The reason is that the toughness of the steel bar and the strength of the concrete can withstand the weight of a single large building.

Of course, in ancient China, there were attempts to build high-rise buildings, such as pagodas and pavilions all over the place, but whether it was a pagoda or a pavilion, it was basically based on bricks and stones, and when it accumulated high enough, it was used to start building a superstructure with wood, in order to reduce the load-bearing!

Are stupas and pavilions considered monolithic large buildings?

In ancient times, it may be counted, but looking at the whole modern era, it is really not a large-scale single building.

Naturally, the emergence of reinforced concrete, a super-era building material, immediately shocked everyone!

Especially the foremen, one counts one, and they were all shocked!

"Can you build such building materials, a house covering an area of twenty acres?" Wang Chen looked at everyone and said softly.

Qiu Gongliang has been in the industry for decades!

I have never seen such an artifact building material taken out by Wang Chen!

It can be said that it simply subverts the worldview!

After reading Wang Chen's reinforced concrete! The five foremen and the family members looked at each other and said in their hearts, "Where are you here to build a house, and it is clearly used to build a palace where the heavenly gods live! You are going to change the entire construction industry of the Song Dynasty! They always thought that Wang Chen was a layman who did not know how to pretend to understand, liked to point fingers, and still covered an area of 20 acres of super-large-scale single house? No material could bear that weight! Even if Qiu Gongliang, who has been in the industry for decades, screwed off his head, it would be absolutely impossible to have that kind of building material!

However, no one expected that Wang Chen would actually take it out, a thing that looked like flour, with strips of steel, stones and river sand, subverting their cognition!

Indestructible!

Indestructible!

It is as indestructible as Wang Chen said!

You must know that Zhong Laowu, who is strong and strong, took the hammer of the quarry's special gravel to smash it, but he didn't smash it much!

Isn't this indestructible what is?

How can this not make them feel shocked?

However, this kind of unheard-of magical building materials they professionals have never seen, and they don't even dare to think about it, but today they actually saw it, or rather, it was an eye-opener!

Is Wang Chen in front of him really a layman? Is it really a layman who thinks of anything to point fingers? The five foremen didn't take this matter to heart before, since a few days ago, they thought that Wang Chen couldn't mention this matter again, today, I don't mention it, and let everyone see, what is the top building materials, is this really a layman can get it? Thinking of this, the five foremen couldn't help but smile bitterly!

Absolutely impossible to be a layman!

Because the layman can't imagine the development of this world's top building materials, he won't even understand many of the materials used in the house!

So in their eyes, Wang Chen immediately rose to the level of master of building materials, a master who is even more awesome than Qiu Gongliang!

The reinforced concrete brought by Wang Chen made it possible for them to think that the sky would not be able to happen when it fell, and even the families present who did not know much about architecture could see that as long as there were such building materials, not to mention Qiu Gongliang, who had been in the industry for decades, as long as he knew a little about ordinary craftsmen in the construction industry, he could build a real skyscraper!

At this moment, even Qiu Gongliang, who has been in the industry for decades, was moved, convinced, and completely conquered by the reinforced concrete brought by Wang Chen!

Everyone turned their heads and ears, and they were all stunned!

However, none of them know that the age of the real appearance of reinforced concrete is eight or nine hundred years later.

The invention of reinforced concrete appeared in modern times and is generally believed to have been invented in 1848. In 1868, a French gardener obtained a patent for a reinforced concrete planter and, subsequently, a reinforced concrete beam and column applied to a highway guardrail. In 1872, the world's first reinforced concrete building was completed in New York, USA.

A new era in the history of human architecture has begun!

Reinforced concrete structures were used on a large scale in engineering after 1900!

How could this group of people have seen it?

Even if Wang Yuncang, who had seen Wang Chen's magic many times, was a little suspicious that he was dreaming at the moment, he still looked at Qiu Gongliang, who had not spoken, for the first time, "Uncle Qiu, Mr. Wang's reinforced concrete, what do you think?"

Everyone else also looked at Qiu Gongliang.

Qiu Gongliang smiled bitterly, "Okay." ”

It's so good that it couldn't be better! But these foremen are so uneducated that I can't think of any words to describe it!

Wang Yuncang's mouth was very poisonous, "Then do you still want to screw your head off?"

Qiu Gongliang almost vomited blood, ignored the goods with a black face, looked at Wang Chen and said, "Dongjia, the concrete is good, but I still have some problems." ”

"What's the problem?" Wang Chen asked.

Qiu Gongliang frowned, said: "The main thing is the truncation and bending of the steel bar, although we used a saw to cut the steel bar a few days ago, but the saw blade is broken several, and the bending to form an arc is also a lot of waste, the use of reinforced concrete in the building is naturally not a problem, the key is that if there is no suitable cutting tool and bending tool, it will waste a lot of time, and the saw blade can not withstand the loss!"

That's just as well!

It's okay to rely on a saw one or two, and hundreds or thousands of tons can't tire people to death?

Wang Chen didn't think of this problem at first, but after thinking about it carefully, it really can't rely purely on manpower, but there is no electricity for the time being, and it is impossible to bring anything with the cutting machine!

Wang Yuncang said: "Let your craftsmen work harder." ”

"There's nothing wrong with working hard, but don't blame me for the long time it takes to build the house, the owner will have to pay a lot more money for labor. Qiu Gongliang was very kind, and told the truth, "Although the old man wants to make more money, he can't mention it without mentioning it with a clear conscience." Then he sighed and said: "The reinforced concrete is really magical, the owner let me wait for the eye-opening, it is incredible, but it is too troublesome to make, the steel bar is cut and bent is not solved, and the construction time of the house will be greatly increased." ”

In accordance with ancient techniques.

Cutting and bending the rebar is indeed a bit difficult.

Especially for very thick steel bars, if you use a saw from the Northern Song Dynasty to cut it, it is very likely that you will have to break a few saw blades when you cut it, which is really a waste of time!

Qiu Gongliang and the others couldn't think of the time to quickly cut and bend for the time being.

had to throw this question back to Wang Chen for the time being, after all, the reinforced concrete was made by Wang Chen.

Wang Yuncang was still a little unimpressed, and said: "You are all people who specialize in building houses, so you can't think of a way? The owner invited you to build a house, not to ask you questions." Speaking of this, Wang Yuncang said to Wang Chen: "Right, Mr. Wang?"

"You guys wait here, I'll figure it out. Wang Chen didn't say anything, and walked in the direction of his bedroom.

As soon as he took a few steps, he could still hear Wang Yuncang's voice of dissatisfaction with Qiu Gongliang and the others, Wang Chen knew that it was okay to rely on the technology of the Northern Song Dynasty, but it would indeed waste a lot of manpower as Qiu Gongliang said.

It's almost time to get to the bedroom.

Wang Chen actually has his own idea in his heart, the steel bar did not appear in the ancient building materials, Qiu Gongliang and others can't think of a way to quickly cut and bend it is normal, but Wang Chen is not an ancient person, he knows how to deal with steel bars in modern society.

For example, with a cutting machine.

It's just that the cutter needs electricity.

So, you can't cut steel bars without electricity?

No, according to Wang Chen's knowledge, steel bar cutting is divided into mechanical cutting and manual cutting two kinds, mechanical cutting is unrealistic, not to mention for the time being, and manual cutting often uses manual cutting machine, gram and bolt cutter and other tools, manual cutting machine can meet the diameter of 16 mm below the steel bar, gram is different, the power is very powerful, even 32 mm of steel bar can be cut, as for the bolt cutter is used to cut the wire.

Bending steel bars is also very simple, just buy some manual bending machines and manual hoop bending machines.

In fact, as long as people who have learned modern physics knowledge, they can also make a simple manual steel bar bending machine, the simplest is to punch holes in the wooden board, and then wear bolts, a little more complicated, that is, first use the steel plate to weld a steel bar on the side as the main mandrel, and then use a five-centimeter-long angle iron, weld a steel bar larger than the main mandrel outside the angle iron, make a hole at the head of the angle iron, and then put it on the side of the main mandrel to level it, weld a steel bar at the position of the angle iron hole on the steel plate, and finally punch holes at the four corners of the steel plate and fix it on the wooden board, of course, this wooden board can not be fixed。

In this way, a simple manual steel bar bending machine is made.

It's nothing more than the use of the principle of leverage, in fact, it is not a big trouble, after all, the steel bar is tough and will not break easily.

It's very simple.

But Wang Chen is too lazy to bother.

Hey, if you have this time, you might as well use the location teleportation to return to the modern buying point tool.

What are you wasting that time for?

Too simple bending machine may not meet the standard and waste steel bars, and slightly more complicated ones have to be welded, Wang Chen is too lazy to get them.

How convenient it is to go back to modern society to buy some manual bending machines and hoop bending machines!

Wang Chen felt that the problems that could be solved quickly by relying on modern society could be solved quickly, and the time for building the plant could not be delayed.

Even, as long as Wang Chen believes that as long as he brings some manual bending machines and hoop bending machines, with the wisdom of ancient craftsmen, he will be able to quickly manufacture corresponding tools.

Back to modern times once.

Wang Chen clicked on the positioning teleportation!

The virtual screen immediately popped up, this was his bedroom, and no one would come.

It is more convenient to locate and teleport, if you teleport in the Northern Song Dynasty, it will consume 100 energy points, and if you travel across time and space, it will consume 300 energy points.

However, going back to modern times, it will empty the energy value.

This was tested last time.

Wang Chen originally came back this morning with the last batch of steel bars normally, and the steel bars were still in the mysterious space before they had time to take them out, he wanted to see how much energy was maximum, and whether it would be a waste of positioning and teleportation.

As a result, at a glance, it looked like more than 500 in half a day.

Well, more than two hundred points may be wasted.

Forget it, waste is waste.

Wang Chen clicked on the location to transmit.
