[Roof joint of branch building \/ indoor rain gutter \/ Japanese good house \u3256-2]<\/p>\n

This is Hitachi’s former Ota family residence, part 2.
\nI wrote about the branch format yesterday, but as you can see in the photo, the two buildings are joined.
\nOn the outside, the hipped roof on the front side is attached to the hipped roof on the back side.
\nSince the roof is a sloping roof, valleys are formed, so rain concentrates on the joints.
\nThis type of construction is premised on the rain gutter being exposed indoors.
\nIt will be a large-diameter gutter so that it will not collapse even during heavy rainfall.
\nWell, it can be inferred that the last-minute situation would have happened.
\nIn addition, serious damage can be expected when it snows in winter.
\nTherefore, it seems that it is an architectural style that cannot be found in northern houses.
\nFrom what I’ve seen, I think South Kanto is the limit.
\nHowever, the appearance of this Hitachi house is similar to the “Southern bent house” that went further north.
\nThere is a horse shop in the dirt floor, and the positional relationship between the human-dominated main house and the dirt floor
\nIt seems that it seems to be made like a bent house.
\nRather, I can feel the connection between such a branch building and a bent house.
\nThe top two photos show the “rain gutter” indoors.
\nThe inside of the wood with a trunk thickness of about 30 cm is hollowed out and used.
\nIt is passed in the middle of the building that borders the eaves.
\nIt is attached to the horizontal members of both buildings with something like a bark.
\nThe span is fairly fine, but these features are made only of natural materials.
\nIt is constructed without using hardware.
\nWith this finishing method, it has lasted for a considerable period of time over 300 years.
\nPerhaps the bark for binding was renewed at regular intervals.
\nShould this gutter exceed its capacity, rainwater will overflow.
\nIt is possible that it flowed into the room like a waterfall.
\nJust in case, it seems that the area directly below it is basically a dirt floor.
\nIt seems that the interior space raised above 30 cm was preserved.
\nHowever, maintenance and maintenance of this indoor rain gutter may have been the biggest problem.
\nWhile maintaining the convenience of using this flat surface, the problem of rainwater treatment was solved.
\nIt is imagined that it was a southern bender.
\nAs the main structure, the girders on the main building side are extended longer to form an integrated building.
\nIt seems that the inevitable “valley” on the roof of the annex was suppressed.<\/p>\n

As a universal spatial element of humankind, as an architectural treatment of housing and labor
\nPerhaps there was a process transition of such a structure.
\nThe regional watershed may have been the middle line between the Kanto region and the Iwate \/ Southern region.
\nAfter that, such a branch structure became obsolete, even in the modern floor plan.
\nGiven that it hasn’t survived, it’s a missing link in a residential building.
\nImagine what kind of life you felt in the indoor space of such a branch building and a rain gutter.
\nFirst, there is the problem of “rain noise”. And the end of rainwater
\nI am also interested in how I used it.
\nFrom the state of architecture, it is possible to “visualize” the way people lived in the past.<\/p>\n","protected":false},"excerpt":{"rendered":"
