Since there is no difference between the first-floor portion and the second-floor portion, the frame trunk edge integrated structure that is the gist of the present invention will be described below based on the second-floor portion.

  In a space formed by a pair of columns 2 and 3 made of steel frame and a pair of beams 4 and 5 made of steel frame, a brace 6 made of steel frame and trunk edges 7 to 12 are arranged. Here, with regard to the second floor portion, the pair of beams is composed of a beam 5 that supports the floor plate of the second floor and an upper oblique beam 4 that supports the roof member. Only one brace 6 is disposed in the space. Also, one brace 13 and a plurality of trunk edges 14 to 19 are disposed in another space formed by a pair of columns 1 and 2 and a pair of beams 4 and 5 adjacent to the space. As described above, it is a feature of the present invention that only one brace having a different arrangement direction is arranged in two adjacent spaces formed by a pair of columns and a pair of beams.

  FIG. 2 is an AA arrow view in FIG. 1 and shows a horizontal cross section including the column 2 and the vertical trunk edges 12 and 16. This example is a general residential building, and a square steel pipe of 100 mm × 100 mm × 3.2 mm 2 is used as a member of the pillar 2. That is, a square steel pipe having a square cross section with an outer dimension of 100 mm on one side and a wall thickness of 3.2 mm is used. In addition, as the material of the trunk edges 12 and 16, a steel base material (stud) for construction of 100 mm × 45 mm × 10 mm × 0.8 mm is used. That is, it is an architectural steel base material having a wall thickness of 0.8 mm. Such a thin and light construction steel base material can be used only by attaching wall panels (not shown) to the trunk edges 7 to 12 and 14 to 19, and the trunk edge is a strength member. It is not. In addition, 100 mm × 45 mm × 10 mm × 0.8 mm building steel base materials 20 and 21 having the same dimensions as the trunk edges 12 and 16 are fixed to both sides of the column 2 by welding or the like, and have the same functions as the trunk edges.

The steel base material 8 for steel can be incorporated as it is and bonded by welding or the like. As a result, strictly speaking, the outer surface of the runners 22 and 23 protrudes by 0.8 mm from the outer surface of the brace 6 and the width of the trunk edge 8, but the value is very small. There is no actual damage when the panel is mounted, and the inner and outer surfaces of the runners 22 and 23, the brace 6, and the trunk edge 8 can be handled as substantially the same plane.

  FIG. 4 is a cross-sectional view taken along the line CC in FIG. 1 and shows a cross section of the upper oblique beam 4. An H-section steel, which is a general structural steel, is used for the upper oblique beam 4. In order to facilitate the connection with the body edge 8 on the lower surface of the H-shaped steel, 102 mm × 40 mm × 0.8 mm thin and light channel steel is fixed as a runner 24 as a fixing material. Similarly, 102 mm × 40 mm × 0.8 mm thin and light channel steel is fixed to the upper surface of the beam 5 supporting the second floor plate as the runner 25 in order to facilitate the connection with the trunk edge. By using the channel steel having such a cross-sectional dimension as the runners 22 to 25, an architectural steel base material that is a body edge of 100 mm × 45 mm × 10 mm × 0.8 mm whose outer width dimension of the cross section is 100 mm. It can be assembled as it is and coupled by welding or the like. As a result, the inner and outer surfaces of the runners 22 to 25, the beams 4 and 5, and the trunk edges 7 to 12 can be handled as substantially the same plane in the same manner as the connection in the brace 6 member described above.
