2. Description of the Related Art H-section steel having flanges at both ends of a web is widely known as a high-strength building material, and has various uses such as construction of steel frame construction and construction of roofs, walls such as inner and outer walls. Is used for. In particular, in the construction of roofs and inner and outer walls of general buildings, and inner and outer walls such as middle and high-rise buildings and super high-rise buildings, the H-section steel is often used as a structural skeleton. In this case, concretely, as shown in FIG. 1, precast concrete or the like is preliminarily formed on the outer surface of the first flange portion 12 'of the web portion 11' of the adjacent H-shaped steel 1'which is assembled as a structural frame. A structure is widely adopted in which the formed wall underlayer material 50 is stretched over, the end face interval is filled with joint mortar 6, and an inner / exterior material (exterior material 72 in the drawing) is fixed to the outer surface thereof. Incidentally, in the figure, reference numeral 40 is a fireproof coating layer processed on the surface of the H-section steel 1 '. Further, as shown in FIG. 2, the first flange portion 1 of the H-shaped steel 1 '
On the outer surface of 2 ', a deck plate (abandonment form material 2) having a structure in which valleys and ridges are alternately continuous is stretched, and concrete 3 is cast (painted) on the upper surface of the abandonment form material 2 in situ. A structure in which an exterior material 72 which is a roof material is fixed to the outer surface thereof is also widely adopted. In the figure, reference numeral 4 is a fireproof coating material for protecting the H-section steel 1 ′ from being directly exposed to the flame from the inside. The wall body thus constructed has high strength because the concrete 3 can be filled also in the outer space of the valley portion of the discarding form material 2. Further, although it is a floor structure rather than a wall body, in order to provide each wiring for high electric current, low electric current, and telephone in the structure, for example, a part of the deck plate is disclosed as in the structure described in JP-A-2-272137. A method of using the outer space of the valley or the inner space of the mountain as a passage for wiring has also been adopted. on the other hand,
Several proposals have been made to improve the conventional H-section steel, for example, the section steel described in JP-A-6-328152 has a corrugated web portion to improve the yield strength. The shaped steel described in Japanese Patent Laid-Open Publication No. 2004-242242 is such that the middle of the web portion is bent to increase the second moment of area in both X and Y axis directions.

[0003]

However, in both the method of using the precast concrete board and the method of using the deck plate, the wall base material and the structure are supported on the outer surface of the first flange portion 12 'of the H-section steel 1'. Therefore, the sum of the length of H-section steel 1'and the thickness of the wall base material and the structure is the thickness of the wall, which causes the effective use space such as the living space to be narrowed. It was Therefore, in order to secure a certain effective use space, it is necessary to expand the entire building, which requires more building materials such as interior and exterior materials, resulting in higher material costs and construction costs. A large area was also needed. In addition, JP-A-6-328
The shape steels described in Japanese Patent No. 152 and Japanese Patent Application Laid-Open No. 6-120278 only improve the proof stress of the shape steel itself, and cannot solve the problem of the wall thickness. It was Further, when a foamed resin board or wood wool cement board that contributes to heat insulation and sound absorption, or a composite board of them is used as the discarding form material 2 instead of the deck plate, the structure of concrete itself to be cast on the outer surface thereof. Since the weight intensively acts on the foamed resin board or the like on the outer surface of the first flange portion 12 'of the H-shaped steel 1', there is a risk that the wall may be displaced after the completion of the work.
