ASTRONOMIC OBSERVATION DOME IN WHICH METAL PLATE IS WELDED TO FRAME WORK FOR REINFORCEMENT

摘要

PROBLEM TO BE SOLVED: To provide an astronomic observation dome in which, weight is not increased, rigidity of the astronomic observation dome is improved, the dome is split in a state an exterior sheet metal is pasted for transportation, precision of the astronomic observation dome is improved, a construction period at a site is shortened, a cost is made down at the site, a technique of an engineer is of lower cost, workers are assured, a finished quality is constant, and durability after delivery is improved.;SOLUTION: In an astronomic observation dome, a metal sheet is welded to an outside frame for raised rigidity, so that deformation rate is significantly reduced.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
