Tiles are pottery products. In terms of Tang Zheng’s current civilization level, have the words at hand.

But the angle between him and the ancients is different.

The other thing he has to consider is--

The catastrophic rainstorm a day later.

What scale of rainstorm?

Heavy rain? Pouring down?

This is just the native world's adjective for heavy rain.

But Tang Zheng is certain that in this world, the formidable power of heavy rain is definitely more than that.

Otherwise, it will not be guilty of repeated notifications around the world.

Under the formidable power of heavy rainfall, it is unknown whether the thin corrugation can withstand the baptism of heavy rain.

Tang Zheng is impossible to gamble on the probability of'may be able to bear, may be penetrated'.

Because it was on the day of the catastrophe, he didn't have time to rebuild another roof.

"If the tiles don't work, you can only think about mud bricks." Tang Zheng stared at Moffett who was still finishing up not far away, rubbing his chin and thinking.

At present, the best house material available is mud bricks.

Using iron metal to make the roof, the load-bearing capacity of the wall may not be enough.

In terms of thickness, mud bricks are also hard enough to resist rainstorm baptism.

How can the ceiling made of mud bricks not collapse?

Tang Zheng searched through the Encyclopedia of All Things and found no related records.

In the early days of the Bronze Age, the ancients had already started building roofs with thatch and tiles, because they did not need to withstand the extreme rain baptism.

Open the forum, enter the keyword "roof", and click search.

It turned out that Tang Zheng found a post three days ago.

[Sharing a strong roof structure, mother said it was very practical when I saw it! 】

Click in and take a look, Tang Zheng's eyes suddenly shine, and he pats his thigh.

Is this something I can see without spending money? !

Reward! Must be rewarded!

Reward heavily!

Tang Zheng rewarded a virtual coin to the player with the ID of'Ping Ping Wuqi Construction Worker'.

――――

Thank you for the 100 book coin rewards from the "who in this guy"!

Thank you so much!

Kow your head!

peng peng peng!

Chapter 37: Stone house construction is completed, the cataclysm is coming [second more]

The illustration provided by the player is a This kind of mortise and tenon structure building roof.

The so-called tenon and tenon joints are the cultural spiritual inheritance of Chinese craftsmen. It originated in the Hemudu era about 7000 years ago, and its history is longer than words.

To put it simply, it is to cut two or more parts into concave and convex shapes, and then combine them.

There is no need to use nails or bindings in the whole process, it follows the mechanics perfectly, and is very strong and firm.

Similar to the current puzzle.

But compared to simple puzzles, the process of tenon and tenon joints is undoubtedly much more sophisticated and complicated.

The most common mortise and tenon structure on the market is usually some expensive redwood or pear wood furniture, which is not easy to corrode and is easy to disassemble and clean.

The player provided a very detailed tenon and tenon roof structure, which can be spliced ​​with wooden boards.

Then put a layer of leaves and mud on the top, and a roof is completed.

Tang Zheng checked his posting time.

Three days ago, there was no global catastrophe warning, and the roof of this structure worked normally.

But now it needs to be improved. Put another layer of mud bricks on the tenon-and-mortise roof and compact it with mud.

In this way, the double roof.

Invincible!

Because of the ingenious structure, the tenon-and-mortise board below will not collapse easily.

What do you mean? Tactical backwards.

What has been inherited from Huaxia Old Ancestor for thousands of years has not been rejected so far, which shows that it is indeed the essence.

Tang Zheng guessed that the original intention of this player’s post was that he might want to gain some forum experience by sharing something he knows well.

In this chaotic world, everyone has to work hard to survive.

It’s just that the popularity of this post is not very high, and there are still many players who curse directly below the post.

[Haban, if I can do this, I still need to read your post? ]

[Thinking Huoxiang is crazy, wasting your dad’s time to come in! ]

[The pictures are pretty good, but I really can’t make them... Send something useful. ]

There was even a reply saying: [Silly egg, there will be a heavy rain tomorrow, can you withstand the heavy rain? No brains at all? ]

Tang Zheng couldn't help but reply on that floor.

[Why can you use the sword of the previous dynasty to cut the current official. ]

After closing the post, Tang Zheng is ready to give it a try.
