<p>PURPOSE: To facilitate the execution work by forming a dome type truss roof fitting lower structural body into a spherical shape via the combination of triangular trusses, and arranging glass roof bodies on the triangular trusses. CONSTITUTION: Six base frames 5 are overlapped on joint casts 4 on the joints 3 of triangular trusses T, and a fitting bolt 17 at the peripheral section of the joint cast 4 is screwed into the hole of each base frame 5. The connection receiver 6a of a setting frame 6 is outwardly coupled with the connection section of the base frame 5, and an outer frame 15 assembled with a roof body R is mounted on the pedestal 6c of the setting frame 6. A back-up material 18 and a sealing material 19 are filled into the gap G between the outer frames 15 of adjacent roof bodies R, and the space in the base frame 15 is used a drainage channel of infiltrating water. The breakage of the roof bodies R is prevented, and the repair work can be facilitated.</p> |
