Description

【０００１】
【発明の属する技術分野】
本発明は、建物の屋根構造に関する。
【０００２】
【従来の技術】
従来、建物の屋根構造として、実公平１−２４２４３号公報や特開平３−５５３４１号公報に記載されているように、複数の建物ユニットからなるユニット建物において、建物構造体の上部に屋根ユニットを設置するとともに、建物構造体の軒先側の上部に屋根ユニットの桁面に連なる屋根ユニットを設置し、さらに、建物構造体に設置した屋根ユニットと屋根パネルとを取付金具で結合した屋根構造が知られている。
【０００３】
【発明が解決しようとする課題】
ところで、従来は、屋根パネルに幅大の軒梁を設け、この軒梁から下方に突出したボルトを建物ユニットの天井梁に予め形成されたボルト挿通孔に挿入することにより屋根パネルを建物構造体の上に設置するため、設置時の位置決めが困難であった。
また、このような屋根構造においては、構成する部材寸法を高精度にすることが要求されるので、高価に付くという問題や、軒元部の固定部品を変更しない限り屋根の勾配の変更は行えないという問題があった。
