PROBLEM TO BE SOLVED: To provide a masking structure in which masking sheets are stretched over both sides of a beam, capable of stretching the masking sheet with high tension without requiring structural reinforcement and which prevents rain from entering into joints of the masking sheet, while ensuring easiness and low costs in construction. ! SOLUTION: The masking structure comprises: a three-dimensional square cylindrical beam 4; and a masking sheet 2 having a sheet body 10 and strip-shaped covers 11 on the periphery of the sheet body 10. The sheet body 10 has a plurality of biding sections 12 along the sides of the sheet body 10. The strip-shaped cover 11 is coupled at ends thereof to the sheet inside the array of the binding parts 12, and has a length long enough to cover the binding parts 12 and the beam 4 and reach the adjacent masking sheet 2 on the other side of the three-dimensional beam 4. The strip-shaped covers 11 of the masking sheets 2 are layered over each other and folded together on the |
