(57) Abstract Objective The steel sheet make circle in the country elevator and the likeThe drainage of the cylinder silo levee crown is good, the steel sheet make whose at the same time cost is lowLevee crown structure of cylindrical silo. Constitution When heat insulation material 16 is provided in the surface of roof steel sheet 15Together, the concrete top board 17 conservation heat insulation material 16 facilitiesAccording to the levee crown rim which becomes the ke te, the said concrete top board 17Although parapet 18 stand facilities is done to the ri high position the heat insulation materialWith 16 and roof steel sheet 15 surface gap component 19ProvidingTo make the te surface void form 20, the said surface void 20 the aforementioned levee crownBelow aperture to the said parapet 18 in the inclined low-order sectionIt makes section drain port communicate 23. In addition, on the said lower part drain port 23Upper drain port 24 aperture to the section vicinity, aforementioned lower part drain port 23And vertical drain 25 is jointed to the said upper drain port 24.
