"Pit dwelling model" that understands the structure of the building

Children's Science May 2021 issue "Interesting Craft Development Site Kodomonokagaku Research Institute" is a "pit dwelling model" that shows how a building works.

Simplify the pit dwelling, complete a paper craft that allows you to understand the general mechanism, and decorate it nicely.

This is a prototype photo.

There are a few things I didn't write about in this magazine, so I'll write them down.

As shown in this diagram, there are various types of pit dwellings, such as Fushiya A type, Fushiya B type, and Fushiya C type.
The model I made this time is a two-stage fushiya style.

If you follow the making method with a model
[Pillar + Beam + Girder] parts up to the point where four pillars are erected, beams and girders are placed on top of the erected pillars, or they are fixed by fitting or tying them together.

On top of that , sasu and ridgepoles are assembled,
[purlin + roof material] parts.

The place where the rafters are hung is
[Rafters + roofing material] parts.

If you use grass for the roofing material, you can enjoy the atmosphere of thatching a roof...! Something like that.
It seems that not only plants were used, but also soil was used.
Produced using a transparent PVC board about 0.2 mm thick,
Carefully cover it with soil to dry it out, and if you look up from the bottom, you can see the atmosphere inside.

Also, the hearth in the middle is important.
Adjust the humidity, keep dangerous animals away,
It seems that they had various roles, such as preventing too many insects and molds.
Besides...the fact that there is always fire may have had an outstanding effect on maintaining the mind, somehow made me realize.

When people study and think about the structure of architecture and the living environment in the olden days when people started to build their own houses, they are very close to nature, such as soil, wood, water, temperature, light, and darkness, so they can directly deal with it. I think it's quite interesting to gradually understand the ingenuity of the time when I was working.

See you next time.
