PROBLEM TO BE SOLVED: To provide sufficient natural lighting indoor from the outside by providing a glass in a state of inclination by a predetermined angle against the upper part of the outside between the ceiling part of the lower part of the outer circumferential end edge of a roof and the upper end part of the wall standingly provided in the nearly vertical condition on the inside from the outer circumferential end edge of the roof. SOLUTION: For example, a transparent wired glass 20 is arranged in a state of inclination by a prescribed angle against the upper part of the outside, between the H-steel of the upper end part 13a of a wall 13 and the lower piece 3b of the H-steel 3 of a roof 1. This glass 20 is arranged between the outer circumferential end edge lower part of the roof 1 and the upper end part of the wall 13 by respectively fixing holding metal fittings 21, 22 provided on the upper and lower end parts 20a, 20b in the width direction of it to the respective H-steel by welding. Hence, by connecting the upper end part 13a of the wall 13 with the ceiling part through the glass 20, light from the outside can be sufficiently taken in the room of the uppermost story through the glass 20, and because a space part is formed between the upper end of the wall 13 and the connecting part of the ceiling 9, the blocking feeling in the room is lightened even in the case of a low ceiling. |
