PROBLEM TO BE SOLVED: To provide an insulation structure of a beam and a method for forming a heat insulation line of a building, in which the number of components can be reduced as much as possible and construction labor (construction process) can be suppressed to the utmost.SOLUTION: A beam lower heat insulation part 34 is flatly formed and thus simplified as a member. Although the member may fall during construction since the member is installed below a steel frame beam 15 and faces it, an upper end header surface 33a of an exterior wall heat insulation part 33 abuts on an undersurface 34c of an outdoor side header part of the beam lower heat insulation part 34, so that the outdoor side header part is held between the exterior wall heat insulation part 33 and the steel frame beam 15, thereby preventing the beam lower heat insulation part 34 from falling. Accordingly, construction labor for preventing the falling can be eliminated. |
