Chapter 223 Centipede Bridge

During the entire construction process, Xu Jingxing really didn't use any fixing tools at all. Nails, ropes, and buckles were all useless, and the logs were not treated in any way. up.

Not to mention that Lao Bai and the carpenters were a little suspicious, even An Xin didn't quite understand, "Master, what's the reason? It looks familiar, but I can't figure it out."

"You, thanks to the fact that you are still a high school student, you can't even understand this?" He smiled and tapped An Xin on the head, and then began to explain the rationale.

The principle is actually very simple, it is the most basic physical principle, involving a little bit of leverage.If a simple explanation of the principle is more abstract, you can take a look at how those who like to stack coins stack them. You can use coins to press one by one without using auxiliary tools such as glue. You can use coins to stack them on an exaggerated scale. and styling.

In fact, the principle is the same, and it is easier to stack logs, because the logs are longer and can exert a stronger supporting force in the principle of leverage. As long as you find the right point of strength, it is as simple as it is to build.

Of course, this is not his original creation, but there are similar buildings in this area, but most of them are bridges, the most typical one is the wooden arcade bridge.

The wooden arch bridge is also called "centipede bridge" by the locals, because the bridge arch is built with round logs, and the supporting logs stretched side by side are a bit like centipede legs, so it has such a vivid nickname.

In Taishun County, south of Kecheng, there are many covered bridges, which are known as the "Hometown of Thousand Bridges" and "South Zhejiang Bridge Museum". A wooden arch structure made of logs.

The bridge with this structure is easy to make. You can find a few logs and have a knowledgeable teacher guide you. It can be built in half a day, and it is easy to disassemble and maintain. It is very suitable for folk construction.The most important thing is that the bridge with this structure is actually quite strong, as long as there is no flood, as long as it is not damaged by man-made, it can be used until the logs decay.

In the "Hometown of Thousand Bridges", there are still some wooden arch bridges in use in the Ming and Qing Dynasties. Among them, the Lanxi Bridge built in the Ming Dynasty has a single-hole span of 36.8 meters, almost reaching the limit of the single-hole span of a wooden arch bridge. And it is still well preserved, which can fully guarantee people's daily travel.

In addition to Lanxi Bridge, there are more than [-] wooden arch bridges such as Sixi Sisters Bridge, Sankui Xuezhai Bridge, Luoyang Xianju Bridge, Xiaocun Wenxing Bridge, and Santiao Bridge. Three of them are older and dated to the Southern Song Dynasty. It was built in Shaoxing seven years ago.

And this is only the number of Taishun County. If it is extended to the entire Jiangnan and even includes the southwest region, the number of wooden arch bridges will be even greater.

Of course, it is relatively rare to use this principle to build a house, because a house built with logs is not a permanent residence after all, and most people don't know how to build it.Although the principle is simple, it is not so easy to apply the principle in practice, because the gap between theory and practice is too great.

Xu Jingxing's explanation was clear, and An Xin could understand it, but she still felt a little unbelievable when she looked at each piece of wood, and if she was really asked to do it, she would still be dizzy.

Easier said than done, this is the truth.

After only two hours of work, all preparations were completed, Xu Jingxing pointed to the shelf that was put up before and said with a smile, "Okay, it can be dismantled."

"Really demolition?" Lao Bai asked a little worried.

"Of course, why hesitate?" Xu Jingxing asked back.

"But, I mean, these wooden walls are so high, if they fall down, they will crush people to death," Lao Bai looked at the trembling log house with a little trepidation, his worry was not unreasonable, it was just built The log house looks like it is completely supported by the lower frame. Once the frame is removed, it may collapse at any time. Smashed into meat paste.

Seeing this, Xu Jingxing smiled, went in and began to dismantle it by himself. His strength was great, and he dismantled a large area in a short time.When the brackets were removed, the logs that were built to a height of about three meters sank suddenly, as if they were about to collapse at any moment. A kind of carpenter screamed and rushed to rescue people, but in the next second, the logs that seemed to be about to collapse Instead, the house stabilized, and under the action of the log's own gravity, the overall structure became more stable.

At this time, everyone finally understood the principle, and breathed a sigh of relief. They boldly came in to help dismantle it, but they were always on tenterhooks during the whole process, and would run wildly at the slightest sign of trouble.

Only Xu Jingxing was always calm and calm, and he was relieved until later, and he followed suit.

After removing the brackets, he jumped on the roof and stepped on some logs that had not fully endured the force, which would make the whole structure more stable. The waterproof cloth was covered after the cattail grass, and then a layer of logs was pressed on the waterproof cloth.

At this time, a shed made of logs without any fixed tools is considered complete.

The entire shed is more than three meters high, with an interior space of about two or eight meters, covering an area of ​​[-] square meters. It is divided into three suites, a living room and two bedrooms. The thick rosin mixed with the fragrance of cattail grass gives a refreshing feeling.

And he cleverly set aside four windows, one for each of the two bedrooms, two for the living room, and of course, a main entrance.

At this time, look at this simple shed again, and think about the whole process of building it. It is as simple as building blocks, but all the carpenters present are aware of the difficulty. You must know that Xu Jingxing was completely unprepared and did not do this. The result of the on-site performance in the case of the design drawing, and the whole process was completed in one go, without mistakes, without rework, and even the number of logs used was similar to the previous estimate, and only a dozen were left idle after construction.

To achieve this level, it is not simply enough to say that you have rich experience, you must have a solid foundation.

Realizing this, a kind of carpenter looked at Xu Jingxing differently from before. Not only did he have a sense of identity, but he also had some respect. Craftsmen had nothing but respect for craftsmen with higher skills.

An Xin gave Xu Jingxing a thumbs up quietly, with a proud expression on her face, as if she felt that it was a great honor to have such a powerful master.
