Following the fact that a lot of falling off of ceiling of building which had large-scale space occurred in the Great East Japan Earthquake, revised Building Standard Act enforcement order was enforced in April, 2014. In this way, about specific ceiling (※ see below) when we built newly, conformity to new standard was demanded. On the other hand, about specific ceiling of existing facility, there is not retroactivity to new standard, but of ki*fu*kaku became handled.
Therefore repair ki*fu*kaku and all identification ceilings such as use of citizen facilities that it was to ensure the civic security in Yokohama-shi, and to be able to carry out role of disaster prevention function at disaster enough; make it a principal, and plan as possible reduction of damage by ceiling falling off. We devised "Yokohama-shi community building ceiling falling off measures business plan" to promote this steadily and premeditatedly.
Thing such as the height of the ceiling exceeds 6m on hanging ceiling and the horizontal projection areas exceed 200m2 and weight of ceiling material exceeding 2 kg/m2.
Target facility: 102 facilities (138)
Facility (excluded from object about elementary and junior high school, high school, special support school for measures completion plan of 2015.) which has specific ceiling among the existing community buildings of Motoichi
Aim annual of business completion
2022 (Raiwa 4) (we assume "Yokohama-shi earthquake disaster prevention strategy" and aim annual plan that we matched.)
We push forward while taking trends of falling off degree of risk of ceiling, importance of function that you should perform at the time of disaster, repair technology and grant into consideration. In addition, we consider securing of civic service about use of citizen facility.
We divide into the first group and the subsequent second group aiming at business starting by priority at first for three years and promote.
