From 10:00 on July 3rd (Saturday), we have been observing the restoration work of "Matsuno Chaya" in Hamarikyu Onshi Park. . About 20 people participated.
The Tokyo Metropolitan Construction Bureau Eastern Park and Green Space Office, the Cultural Property Building Preservation Technology Association, and the Township Construction explained.
At present, the framework of the building has been formed, and he explained the roofing work.
The pillar material has a beautiful grain of toga, and it was said that it had a hard time finding such a high quality in Japan. The base is cypress.
The roof structure is east Asian hip-and-gable roof.
They performed a demonstration of the roofing (the material is Japanese Spanish mackerel) in different places. We also hit the bamboo nails to our visitors, and we had a very good experience because we could not do it without such an opportunity. The tools inside the bamboo nails can be seen in the picture are also special.
This is a method of contacting two pillars. I tried how to divide it into two in a state where it was touched, but I didn't know. It's really good enough to know when it actually disassembled it. I was surprised by the skills of Japanese craftsmen.
The photo below is also processed to match the shape of the foundation stone during the Edo period. In this way, the craftsmen's skills were seen everywhere.
In addition, various seismic reinforcements have been made according to the current building standards. I can't see it when it's done, but it was a good experience to see such a device.
Reinforcing the wall with steel frames
It seems that the strength is enough with thick pine beams, but it has braces.
It was a tour of about an hour, but it was an interesting tour that was so interesting that I didn't have enough chot time. It is said that it will be completed in November this year, but I'm looking forward to it. If there is such a tour, I would like to participate.
