Suppliers from both worlds have dominated the world since Datang!

The next day, it was dawn.

Zhuang Zhou got up and ate breakfast in a hurry.

Then I got on my motorcycle and went straight to the grocery store.

Then go straight back to modern times and head straight to the building materials market.

This time, Zhuang Zhou planned to purchase more.

Because the warehouse he wants to build is not small.

The amount of materials required is also quite large.

Especially along with greenhouses, these all require materials.

First, there are shovels, steel drills, steel tape measures, iron sand buckets, Luoyang shovels, safety belts, safety ropes, gloves, etc.

Anyway, I bought them all because I thought they would be useful.

Then there are steel, screws, nailers, rammers, stone crushers, etc.

These are essential.

In addition, Zhuang Zhou is also planning to purchase some cutting machines and welding machines.

Although this is outdoor work, it is still essential.

To this end, Zhuang Zhou also bought two generators for backup.

I also stopped by the hardware store and bought electrical wiring boards, iron wire and the like.

After purchasing all this, Zhuang Zhou contacted Zhang Liang again.

This professional does things differently.

It was originally said to take two days, but it ended up taking only one day and one night.

Zhang Liang finished the drawings.

Zhuang Zhou was very satisfied after reading it and could start construction directly with the drawings.

When asked about paying the design fee, Zhang Liang asked for 8,000 yuan.

Zhuang Zhou directly transferred ten thousand to him.

Then he printed out the drawings and returned directly to Chang'an City.

……

At noon.

Zhuang Zhou came directly to Lishan.

Workers have dug the foundation and are tamping the soil.

Seeing the busy figures of the workers, Zhuang Zhou felt relieved.

The foundation was dug about one and a half meters deep and then compacted with a mixture of lime, river sand and gravel.

And the tamping tools are even simpler.

It's just two wooden sticks tied to a square stone.

The two men carried it and relied on the gravity of the stone to compact it.

In this era, most houses were built using this method.

But in Zhuang Zhou's opinion, such a foundation is not stable at all.

If there is too much rain, subsidence will occur.

After compaction, masons began to lay bricks.

This is too watery!

Zhuang Zhou quickly stopped and called everyone together.

Expand the drawings and let everyone look at them and explain them at the same time.

Only then did everyone see clearly.

It turns out that this warehouse, which covers an area of ​​600 square meters, is a single building.

In other words, it is purely a large span of nearly seven feet (20 meters).

The most ridiculous thing is.

There isn't even a pillar in the middle of the ceiling.

"Mr. Zhuang, can't you repair this roof?"

At this time Xu Dingguo was worried.

Zhuang Zhou took a look and asked:

"What's wrong? Why can't it be done?"

"Too wide!"

Xu Dingguo continued:

"It's no problem if it's ten feet long, it can be any longer.

But you are nearly seven feet wide, how can you hold it up?

Unless all columns are added in one row, it can be solved. "

Zhuang Zhou finally understood what he meant.

This is a carpenter who usually uses wood to build ceilings.

Of course he had never seen a roof made of lightweight steel.

According to national standards, the maximum span of steel structures can reach 36 meters.

He is only 20 meters old, so it is completely solvable.

A large roof of 600 square meters.

This is something they never dare to think about.

Next, Zhuang Zhou took out the cement again.

Then he asked people to haul some river sand and gravel over.

Prepare to make cement mortar and lay the foundation.

But before that, Zhuang Zhou arranged for carpenters to prop up wood on the original tamped foundation.

That is to make a square slot.

Once the steel cage is completed, cement mortar can be filled directly inside.

River sand and gravel were found and packed in bamboo baskets.

"Dr. Zhuang, what do you want us to do by asking us to find river sand and gravel?"

Zhuang Zhou then put a bag of cement on the ground:

"Do you know cement?"

"What do you mean?"

"Adding water to the mud?"

"..."

Zhuang Zhou used a utility knife to cut open the cement bag and said:

“This is called cement ash, and it is used to strengthen the foundation load.

Now, tamping the foundation is only the first step, and a ring of ground beams must be built on top.

Only then can we start laying bricks, so that the foundation will be solid. "

"Ground beam?"

Xu Dingguo pondered slightly, but obviously still didn't understand.

Zhuang Zhou explained:

“This cement, as long as it is mixed with sand and gravel in proportion and water is added, it can form cement mortar.

Once this cement mortar dries, it will become extremely hard.

If you add steel frame keels to the cement mortar, it will become unbreakable.

It’s okay to manage it for any number of decades. "

Having said this, Zhuang Zhou took out his newly bought shovel and started mixing the ingredients himself.

These are the proportions that have been checked in advance.

But wait until Zhuang Zhou mixes cement, river sand, and gravel together.

One of them joked:

"Have you noticed that this cement dust really looks like flour?

Is it edible? "

It would be better not to mention this.

As soon as he mentioned it, Zhuang Zhou immediately realized a problem.

These are the people who have never seen cement dust.

Maybe, someone will actually eat it!

So there are some words that need to be carefully warned:

"You all remember, you must not eat this cement ash!"

"Why can't you eat it? Is it poisonous?"

someone asked curiously.

Zhuang Zhou shook his head and explained:

“It’s not that it’s poisonous, but once the cement ash enters the human body, it will solidify into a hard block.

Think about it, if you have a lump in your stomach, can you still live? "

When everyone heard this, their expressions changed.

He was obviously frightened by Zhuang Zhou's words.

But soon someone became suspicious again:

"Can this cement ash really harden?"

"Of course you can! I will give you a demonstration now, so you can watch it."

Seeing this, Zhuang Zhou quickly added:

"Also, when handling cement dust, it is best to wear gloves to avoid skin contact."

Everyone nodded, indicating that they remembered.

Zhuang Zhou felt relieved and continued to mix the ingredients.

Soon, the cement mortar was ready.

Zhuang Zhou personally demonstrated how to lay a steel cage in the trough.

In fact, Zhuang Zhou also made this thing when he was young, watching his family renovate the house.

it's actually really easy.

Then fill with cement mortar.

Seeing this, everyone gathered around and studied hard.

Zhuang Zhou demonstrated and explained at the same time, for fear that everyone would not understand.

Fortunately, these workers were all veterans and quickly mastered the ropes.

The section we are working on now is probably less than three meters long.

Wait for the cement mortar to be filled in.

Zhuang Zhou found another root and poked it back and forth.

Everyone couldn't help laughing when they saw this.

"Mr. Zhuang, why did you poke it?"

Zhuang Zhou explained:

“This is to eliminate the air in the cement mortar, think about it!

If there is air in it, wouldn't it be empty when it dries out? "

Only then did everyone realize.

Then they all found wooden sticks and started stabbing them together, imitating Zhuang Zhou.

I originally bought a plug-in concrete vibrator.

But this thing requires electricity.

You have to get the generator out.

But today cement and steel bars have been shown.

It’s better to take it slow!

Too much high tech revealed at once.

It's really hard to explain.
