The top-side lighting frame unit 1 is attached to a first block A, which is mounted on a horizontal frame X formed of an appropriate beam and a beam, which is formed on an upper part of a wooden shaft frame constituting the second block B. Projects upward from the ridge. However, the building structure, planar shape, roof shape, and the like of each block are not particularly limited in the present invention.

  Top windows 20 and 30 are provided on the beam surface and the wife surface of the top lighting frame unit 1, respectively, and a sky window 40 is also provided on the top surface provided with the gradient. A structure for ensuring the maximum opening of these window openings will be described with reference to FIGS.

  The top lighting frame unit 1 is composed of four column members 5 arranged at four corners of a substantially rectangular plane, a beam member (a lower beam member 21 and an upper beam member 22) and a beam member (a lower beam member 31 and an upper beam member). 32), and the six structural surfaces, that is, the girder surface and the wife surface opposite to each other, the top surface, and the bottom surface are all frames having high rigid bodies.

  FIG. 5 shows the structure of a girder frame that constitutes the higher (ridge side) girder surface of the girder surfaces opposed to each other with a height difference. In the illustrated embodiment, the cross-section of the pillar material 5 that is practically assumed is a square of about 12 cm square, and the width of the lower girder material 21 and the upper girder material 22 is also about 12 cm. The height of the lower girder material 21 is about 33 cm, and the height of the upper girder material 22 is about 27 cm, so that a column-shaped frontage extending about 4 m is formed.

  The joints between the column member 5 and the lower girder member 21 and the upper girder member 22 are rigidly joined to each other via a steel connecting hardware 61. The illustrated connection hardware 61 is a combination of a plate and a plurality of tenon pipes. The plate is inserted into a slit formed at the end of the lower girder material 21 and the upper girder material 22 to form the column material 5.
