PROBLEM TO BE SOLVED: To provide a ceiling hanging bolt installation device to enable a ceiling hanging bolt to be stiffly and horizontally installed on a steel purlin fixed to roof materials having a variety of inclinations.SOLUTION: A steel purlin 3 which is a horizontal material made of lipped channel steel 3 is fixed to an orthogonally-crossed steel roof frame 2 installed at an angle in accordance with varying inclinations of a roof material 1. A ceiling hanging bolt 4 is installed on the lipped channel steel 3 with mounting hardware 5. The mounting hardware 5 has: a horizontal base piece 6 provided with a screw hole 6a where the ceiling hanging bolt 4 is vertically inserted thereinto and screwed shut; and erecting pieces 7 and 8 which are erected from both edge sections of the horizontal base piece 6. One erecting piece 7 or 8 is engaged with a lower lip section 3e of the lipped channel steel 3 and the other erecting piece 8 or 7 is screwed to a vertical flange section 3c of the lipped channel steel 3. The ceiling hanging bolt 4 is screwed into the screw hole 6a on the horizontal base piece 6 with an upper edge section 4a of the bolt 4 pressed against and contacted with a lower face of a lower flange section 3c of the lipped channel steel 3.SELECTED DRAWING: Figure 1
【課題】種々の勾配角度の屋根材に取り付けられる鉄骨製母屋に天井吊りボルトを強固に且つ水平に取り付けるための天井吊りボルト取付装置を提案する。【解決手段】屋根材１の種々の勾配角度に傾斜して配設される鉄骨製屋根骨枠２に直交して水平材である鉄骨製母屋３を固着し、この鉄骨製母屋であるリップ付き溝形鋼３に天井吊りボルト４を取付金具５によって取り付けるにあたって、取付金具５は、天井吊りボルト４が垂直に嵌挿され且つねじ止めされるためのネジ止め孔６ａを有する水平基部片６と、水平基部片６の両端部から立ち上がる立ち上がり部片７，８とからなり、そのうちの一方の立ち上がり部片７又は８がリップ付き溝型鋼３の下リップ部３ｅに係合され、他方の立ち上がり部片８又は７がリップ付き溝型鋼３の縦フランジ部３ｃにビス止めされ、水平基部片６のねじ止め孔６ａに天井吊りボルト４がねじ込まれて該ボルト４の上端部４ａがリップ付き溝型鋼３の下フランジ部３ｃの下面に圧接するようにした。【選択図】図１
