PROBLEM TO BE SOLVED: To solve the problem that: there are cost increase and a low degree of freedom in the arrangement of equipment and piping, in a structure of a conventional ceiling earthquake-proof countermeasure construction method, since large numbers of braces and the like are arranged.SOLUTION: In the ceiling earthquake-proof countermeasure construction method, a horizontal force support member 4 arranged along the periphery of a wall so as to support a ceiling member, is suspended by arranging a suspension member 5 in the vertical direction, and a lower end part is connected to a connection part between the horizontal force support member and the suspension member, and a brace member 1 is arranged and suspended by connecting an upper end part to an upper beam material obliquely upward relative to the suspension member so that component force resists to horizontal force at the time of an earthquake from the orthogonal direction to the horizontal force support member, and the horizontal force at the time of an earthquake is shared by the brace member 1. |
