Abstract

PURPOSE: To enhance support strength and stability of a handrail wall. CONSTITUTION: In a balcony handrail wall support structure that a floor 15 of a balcony projects more than an outer wall 16 of a lower story and a handrail wall 17 is supported with an outside edge part of this projecting floor 15, the handrail wall 17 is joined to the outside edge part of the floor 15 in a condition where its lower end extends downward more than the floor 15. A lower end part of this handrail wall 17 and the outer wall 16 of a lower story are structurally joined together by an eaves ceiling panel 18. In this way, since the handrail wall 17 is structurally joined not only to the outside edge part of the floor 15 but also to the outer wall 16 of a lower story through the eaves ceiling panel 18, support strength and stability of the handrail wall 17 can be enhanced.
