The next day, it was just dawn.
Zhuang Zhou got up and ate breakfast in a hurry.
Then he got on his motorcycle and headed straight to the grocery store.
Then go directly back to the modern era and head straight to the building materials market.
This time, Zhuang Zhou plans to purchase more.
Because the warehouse he wants to build is quite large.
The amount of materials required is also quite a lot.
Especially there are greenhouses, all of which require materials.
First came the shovel, steel chisel, steel tape measure, iron sand bucket, Luoyang shovel, safety belt, safety rope, gloves, etc.
Anyway, I bought whatever I thought I could use.
Then there are steel, screws, nailers, rammers, crushers, etc.
These are all essential.
In addition, Zhuang Zhou also plans to purchase some cutting machines and welding machines.
Although this is outdoor work, it is also essential.
For this purpose, Zhuang Zhou specially bought two generators as backup.
I also stopped by the hardware store and bought some electrical sockets, wire and other things.
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 seeing it and felt that he could start construction directly with the drawings.
When asked about the payment of design fees, Zhang Liang asked for eight thousand yuan.
Zhuang Zhou directly transferred 10,000 yuan to him.
Then he printed out the drawings and returned directly to Chang'an City.
…
Around noon.
Zhuang Zhou went directly to Mount Li.
The workers have dug the foundation and are tamping the soil.
Looking at 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 tools for tamping are even simpler.
It's just two wooden sticks tied with a square stone.
Two people carried it and relied on the gravity of the stone to compact it.
In this era, this method is mostly used to repair and build houses.
But in Zhuang Zhou's opinion, such a foundation is not stable at all.
If there is too much rain, sedimentation will definitely occur.
After the ground is compacted, the masons begin to lay bricks.
This is too watery!
Zhuang Zhou quickly called a halt and called everyone together.
He unfolded the drawings and gave an explanation while everyone looked at them.
Only then did everyone see clearly.
It turns out that this warehouse covering an area of 600 square meters is a single building.
In other words, it has a span of nearly seven zhang (20 meters).
The most ridiculous thing is.
There wasn't even a single support in the middle of the ceiling.
"Boss Zhuang, can't you repair this roof?"
At this time Xu Dingguo said worriedly.
Zhuang Zhou took a look and asked:
"What's wrong? Why can't you do it?"
“It’s too wide!”
Xu Dingguo continued:
"Ten feet is no problem, or longer.
But how can you build a structure with a width of nearly seven meters?
Unless all the columns in the middle row are added, the problem can be solved."
Zhuang Zhou finally understood what he meant.
This is a carpenter who usually uses wood to build roofs.
He certainly had never seen a roof made of lightweight steel.
According to national standards, the maximum span of steel structures can be 36 meters.
It's only 20 meters away, it's a completely solvable problem.
A large roof of 600 square meters.
This is something they dare not even think about.
Next, Zhuang Zhou took out the cement again.
Then he asked someone to bring some river sand and gravel over.
Prepare to make cement mortar and lay the foundation.
But before that, Zhuang Zhou arranged for carpenters to support the wood on the original compacted foundation.
That is to say, make a square groove.
Once the steel cage is completed, you can directly fill it with cement mortar.
River sand and gravel were collected and put into bamboo baskets.
"Master Zhuang, what do you want us to do by looking for river sand and gravel?"
Zhuang Zhou then placed a bag of cement on the ground:
“Do you know cement?”
"What's the meaning?"
"Is it adding water to the mud?"
“…”
Zhuang Zhou used a utility knife to cut open the cement bag, saying:
“This is called cement ash, and it’s used to strengthen the foundation load.
Now, compacting the foundation is just the first step, and we also need to build a ring beam on it.
Only then can we start laying bricks, so that the foundation is solid."
"Ground beam?"
Xu Dingguo pondered for a moment, but obviously still didn't understand.
Zhuang Zhou explained:
"This cement, as long as it is mixed with sand and gravel in the right proportion and water, can form cement mortar.
Once this cement mortar dries, it will become extremely hard.
If steel frame keel is added to cement mortar, it will become unbreakable.
It’s fine to manage it for a few decades.”
Having said that, Zhuang Zhou took out his newly bought shovel and started mixing the materials himself.
These are the ratios that have been checked in advance.
But when Zhuang Zhou mixed the 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 if you didn't mention this.
As soon as it was mentioned, 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 things that need to be carefully reminded:
"Remember this, everyone. You must not eat this cement dust!"
"Why can't I eat it? Is it poisonous?"
