EXTENSION METHOD FOR BASE-ISOLATED BUILDING
To provide an extension method for a base-isolated building capable of quickly securing structural safety of the base-isolated building even when an earthquake occurs under construction of the extension part.SOLUTION: There is provided an extension method of a base-isolated building for constructing an extension building 3 to an existing building 2. Namely, it includes: steps S2, S3 of constructing a part of the extension building 3 on a newly constructed base-isolation device 50 by installing the newly constructed base-isolated device 50 of the extension building 3; step S4 of constructing parts other than a connection part with the existing building 2 among the rest of the extension building 3; step S5 of limiting lateral distance between the existing building 2 and the extension building 3 within a management reference value range of base-isolation clearance by a jack 70 when the lateral distance between the existing building 2 and the extension building 3 is out of the management reference value range of base-isolation clearance; step S6 of connecting a right-upper floor and the uppermost floor of a base-isolation layer 51 of the extension building 3 to the existing building 2 with a connection beam 72; and step 7 of connecting the rest floors of the extension building 3 to the existing building 3 with the connection beam 72.SELECTED DRAWING: Figure 7
【課題】増築部の建設工事中に地震が発生しても、免震建物の構造安全性を迅速に確保できる、免震建物の増築方法を提供すること。【解決手段】先行建物２に増築建物３を増築する免震建物の増築方法である。すなわち、増築建物３の新設免震装置５０を設置して、新設免震装置５０上に増築建物３の一部を構築するステップＳ２、Ｓ３と、増築建物３の残りのうち先行建物２との接合部以外の部分を構築するステップＳ４と、先行建物２と増築建物３との水平距離が免震クリアランスの管理基準値の範囲外である場合は、ジャッキ７０により先行建物２と増築建物３との水平距離を免震クリアランスの管理基準値の範囲内とするステップＳ５と、増築建物３のうち免震層５１の直上階および最上階を接合梁７２により先行建物２に接合するステップＳ６と、増築建物３の残りの階を接合梁７２により先行建物３に接合するステップＳ７と、を含む。【選択図】図７
