VESSEL WITH AN UPRIGHT SHELL

摘要

???????????? SHELL A vessel, particularly a silo, has an upright shell of circular outline wherein a median part supports an upper part and rests on a lower part. Each of the upper and median parts consists of four arcuate sections which are secured to each other by strips or bars and screws, and the lower portion of the lower part tapers downwardly toward the axis of the shell. The upper portion of the lower part is a collar including a ring of triangular cross section which supports the median part and rests on four ground-contacting supports. The collar consists of four arcuate sections which abut against each other in planes including the axis of the shell and are secured to each other by upright T-bulb-section bars each having two flanges which are secured to the outer sides of neighboring sections of the collar by vertical rows of screws and a bulb which is remote from the collar and is ???ated between the ??????? rows of screws to afford access to such screws. The supports include profiled upright bars and plates inserted between the upper end portions of the support bars and the respective T-bulb-section bars. If the cylindrical outer portion of the ring of the collar extends upwardly beyond the other portion of the ring, the means for securing the sections of the collar to each other further comprises additional upright T-bulb-section bars each of which is ??? row symmetrical to the respective outer T-bulb-section bar and is screwed to the adjacent sections of the cylindrical portion above the other portions of the ring. The center of gravity of each support is disposed below and in vertical alignment with the point where the inner side of the respective outer T-bulb-section bar intersects the corresponding plane of abutment of neighboring collar sections.
