PROBLEM TO BE SOLVED: To provide upper-lower layer connection boundary part that can construct accommodation at a periphery of a part where an upper-lower layer connecting member which enables a building having a different structure to be easily built at low cost is used as a floor above a lower floor of a heavy steel frame structure.SOLUTION: The present invention relates to accommodation at a connection boundary part between a lower layer floor constructed in a heavy steel method and an upper layer floor constructed in a different method from the lower layer floor. The accommodation comprises: a beam H of the upper layer floor constructed with a heavy steel frame; a plurality of upper-lower layer connecting members 1 which are fixed on an upper surface of the beam H, serves as a fitting base for a structure of the upper layer floor, and is formed in a frame shape; a lower layer wall W1 which is fixed to an outer side face of the beam H and serves as an outer wall of the lower layer floor; an upper layer wall P which is fitted directly or indirectly to the upper-lower layer connecting members 1 and serves as an outer wall of the upper layer floor; and a throating material V which covers a boundary part between the upper layer floor and lower layer floor, the throating material being arranged to bridge the part between a lower end part of the upper layer floor and an upper end part of the lower layer wall. |
