Chateau Kamiya Old Winery Facility / Fermentation Facility,an Important Cultural Property, where restoration wascompleted in 2013. Here, so as not to affect the undergroundstorage room, exterior buttresses were installed (photos11, 12). Also, although not an Important Cultural Property,at Rikkyo University’s First Dining Hall restored in 2002, areinforced concrete kitchen annex was added onto the brickmasonry dining hall to burden seismic forces and supportthe dining hall (Yokota 2006). This can be considered to bean alternate method of exterior reinforcement.processes including plaster finish require additional care insubstrate work, as the steel plates are now the surface to befinished.At Meiji Gakuin University Chapel, a Minato Warddesignated cultural property, 9mm thick steel plates wereattached onto the entire length of the inside walls. Similarreinforcement had been earlier executed at Former HongKong Shanghai Bank Nagasaki Branch, an Important CulturalProperty, restored in 1995, but this chapel was the first tobe reinforced entirely fn 3 .３.５. Steel Plate ReinforcementThis is a method of attaching steel plates onto the innersurfaces of brick walls. Steel plates can be fixed with bolts,adhesive, or insertion of resin anchors.Advantages are that the maximum floor area canbe obtained, foundation work is fairly simple, and ifreinforcements are attached only with bolts, they can beeasily removed (Nishizawa 1994-1, p79).There is trouble involved in having to once disassemble theinterior finishes and because the wall thickness is increasedby the additionally inserted layer of steel plate, adjustmentswill be necessary to bring each of the interior fixtures suchas windowsills back into their original positions. Also, wet３.６. Resin Anchored ReinforcementThis is a method of inserting resin anchors from thetop ends of walls into vertically bored holes. Becausereinforcement is inserted into the walls, this technique canbe applied only to thick walls.One advantage is that reinforcement is hidden andcannot be seen from either the outside or inside. Withadvancements in boring technology, holes up to 15m longcan be made. This is a patented technique where if waterlessboring methods are adopted, effects to interior finishes suchas plasterwork can be kept to a minimum. However, evenwhen water is not used, preventive measures against dustparticles dispersed from exposed joints or drilling noise willphoto 9Former Yamagata Prefecture Assembly Hallphoto 11Chateau Kamiya Old Winery Facilityphoto 10 Former Yamagata Prefecture Assembly Hall, buttressreinforcementphoto 12 Chateau Kamiya Old Winery Facility / Fermentation Facility,exterior buttresses26Chapter 3Restoration of Brick Masonry Cultural Property Structures
