MIXED STRUCTURE AND CONSTRUCTION METHOD FOR THE SAME

PROBLEM TO BE SOLVED: To enable a multi-story building with a skeleton mainly of reinforced concrete to be easily constructed.SOLUTION: A mixed structure building 1 comprises: an external skeleton 2 which is constructed of rebar and concrete; and an internal skeleton 3 which is installed in a space S inside the external skeleton 2 and constructed of a material different form the external skeleton 2. The external skeleton 2 has: a first floor body 23; a plurality of main columns 21 upwardly extended from the first floor body 23 with a distance from each other; and a second floor body 23 supported by the plurality of main columns 21 at an elevation higher than the first floor body 23. The internal skeleton 3 has: third floor bodies 59 and 66 which are installed in the space S between the first floor body 23 and the second floor body 23 in a manner that separates the space S into an upper portion and a lower portion; and support members 41 and 51 which are installed between the first floor body 23 and the third floor bodies 59 and 66 and support the third floor bodies 59 and 66.SELECTED DRAWING: Figure 9 【課題】主に鉄筋コンクリートを躯体とする複数階建ての建築物を容易に施工できるようにする。【解決手段】鉄筋およびコンクリートを含んで形成された外部躯体２と、当該外部躯体２の内側に形成された空間Ｓに、当該外部躯体２とは異なる材料で形成された内部躯体３と、を備える混構造建築物１とする。外部躯体２は、第一床体２３と、第一床体２３から互いに間隔を空けて上方に延びる複数の主柱２１と、第一床体２３よりも上方において複数の主柱２１に支持された第二床体２３と、を備え、内部躯体３は、第一床体２３と第二床体２３との間に形成された空間Ｓ内に、当該空間Ｓを上下に仕切るように設けられた第三床体５９，６６と、第一床体２３と第三床体５９，６６との間に設けられ、第三床体５９，６６を支持する支持部材４１，５１と、を備える。【選択図】図９
