EXPLOSION STRUCTURE OF DOME ROOF TANK

摘要

PROBLEM TO BE SOLVED: To provide an explosion structure of a dome roof tank which is easy to construct while an advantage of a dome of exhibiting explosion easily and surely is kept. SOLUTION: The explosion structure comprises an ascending cone-shaped adjust board 7 having a predetermined width and a predetermined small angle inward, which is interposed between an upper face of a top angle 4 fixed to an upper end of a cylindrical side board 3 and an outer peripheral rim lower face of a dome roof 5b formed with an outer diameter smaller than an inner diameter of the side board 3. The upper face of the top angle 4 and the adjust board 7 reduce strength at the time of buckling fracture of a compression bearing of the structure.
