である。2. Description of the Related Art H-section steel having flanges at the upper and lower ends of a longitudinal web is widely known as a high-strength building material, and is used for various purposes such as construction of steel frame construction and construction of floor structures. Has been done. In particular, H-shaped steel is often used as a beam material in the construction of floor structures such as general buildings and middle and high-rise buildings and super high-rise buildings. In this case, specifically, as shown in FIG. 1, a valley portion and a mountain are formed on the upper surface of the upper flange portion 12 'of the web portion 11' in the longitudinal direction of the adjacent H-section steel 1'framed as a beam. A method is widely adopted in which a deck plate 2 having a structure in which parts and parts are alternately continuous is bridged and placed, and the concrete 3 is cast in situ using the deck plate 2 as a scrap frame. In the figure, 4 is an H-shaped steel 1 '.
It is a fireproof coating that protects against direct exposure to the flame from below. The floor member thus constructed has high strength because the space above the valley of the deck plate 2 can be filled with the concrete 3. In addition, in the floor structure,
To provide each wiring for a telephone, for example, JP-A-2-2721
As in the structure described in Japanese Laid-Open Patent Publication No. 37, a method has been adopted in which a space above the valley part of the deck plate or a space below the mountain part is used as a wiring passage. Also, as shown in FIG.
A preformed floor plate material 5 such as precast concrete is placed on the upper surface of the upper flange portion 12 'of the H-shaped steel 1',
A method of filling the gap between the end faces with joint mortar 6 is also widely adopted. Incidentally, in the figure, reference numeral 40 is a fireproof coating layer processed on the surface of the H-section steel 1 '. The floor member thus constructed has excellent workability. On the other hand, some proposals for improving the conventional H-section steel have been made, for example, JP-A-6-3281.
The shaped steel described in Japanese Patent Laid-Open No. 52-52 has a corrugated web portion to improve the proof stress.
The shaped steel described in Japanese Patent No. 78 is obtained by refracting the middle of the web portion to increase the second moment of area in the X and Y axis directions.

なかった。However, both the method using the deck plate and the method using precast concrete described above are used for the upper flange portion 12 'of the H-section steel 1'.
Since the floor member is supported on the upper surface of the floor structure, the sum of the vertical dimension of the H-section steel 1'and the thickness of the floor member is the height of the floor structure, and especially in middle-high-rise buildings and skyscrapers. It was a cause of raising the height more than necessary. If the height of a high-rise building is high like this, a large amount of building materials such as column steel frames and interior / exterior materials will be required, resulting in high material costs and construction costs. Sometimes it developed. In addition, JP-A-6-328
The shaped steels described in Japanese Patent No. 152 and Japanese Patent Laid-Open No. 6-120278 only improve the proof stress of the shaped steel itself, and cannot solve the problem of height.

Although the deck plate 2 is placed on the upper surface of the upper flange portion 12 ′ of the above, in the first form of FIG. 3 in which the floor member is configured by similarly casting the concrete 3 on the spot using the deck plate 2 as a scrap frame, The deck plate 2 is mounted and fixed to the middle flange portion 14 instead of the upper flange portion 12 of the shaped steel 1 having the above-described configuration. In this case, the end portion of the deck plate 2 is supported between the upper flange portion 12 and the middle flange portion 14 in a sandwiched manner. When disposing the deck plate 2, a face door 21 that closes at least the end of the valley portion of the deck plate 2 is arranged, and when the cast-in-place concrete 3 is filled in the space above the valley portion, the end portion is filled. To prevent it from leaking. In addition, the shaped steel 1 exposed below the deck plate 2
A refractory coating material 4 such as asbestos or calcium sulfate plate is provided on the side and the lower side of the to protect the shaped steel 1 from being directly exposed to the flame. In this state, concrete 3 is cast on site to form a floor structure.

になる。As is clear from comparison between the floor structure of the first embodiment shown in FIG. 3 and the conventional floor structure shown in FIG. 1, it is necessary to reduce the height of the floor structure by the thickness of the deck plate 2. You can In a high-rise building, the effect occurs for each floor, so that the overall height of the high-rise building can be reduced. Further, since the cross-sectional performance in the X and Y axis directions is improved, the safety of the building against external force such as seismic force is improved. Further, since the fireproof coating material 4 may cover the middle flange portion 14 to the lower flange portion 13 exposed from the lower side of the deck plate 2, the usage amount can be reduced.

The same effect as that of the floor structure of the first embodiment is obtained. That is, the floor plate member 50 has its end face formed in a stepped shape, and the lower projecting portion 51 is provided with the upper flange portion 12 and the middle flange portion 14.
Since it is supported so as to be sandwiched between and,
The height of the floor structure can be reduced by one thickness. . In addition, the fireproof coating layer 40 made of rock wool or the like is sprayed on the side and underside of the shaped steel 1 exposed below the floor plate material 50 to form the fireproof coating layer 40, and the shaped steel 1 is directly exposed to the flame. I protected it so that it would not be done. A joint structure mortar 6 was filled in the space between the end faces of the adjacent floor board members 50, 50 to form a floor structure.

5 is rising, and bent horizontally to the upper end towards the outside respectively shaped steel 1 2 of the configurations the upper flange portion 16, 16 used, applying a floor member between the deck plate 2 and the poured concrete 3 It was done. It goes without saying that this floor structure also has the same effect as the floor structure of the first embodiment, but particularly in the floor structure of the third embodiment, the cast-in-place concrete is also applied between the upper web portions 15 and 15. Since 3 is filled, the decrease in strength in the beam portion is suppressed as compared with the floor structure of the first embodiment.

なくなるので、耐火被覆費用が軽減される。In summary, the shape steel of the present invention, when applied to a floor structure, can reduce the height of one floor by the thickness of the floor plate such as a deck plate without lowering the strength. Therefore, when it is applied to the construction of a high-rise building, its effect occurs for each floor, so that the overall height of the high-rise building can be reduced. As a result, it is possible to reduce costs such as the cost of building materials such as pillar steel frames, interior and exterior materials, and construction costs in high-rise buildings. However, the cost of the shaped steel alone rises, but all the members in the height direction can be saved,
Since the strength condition is also reduced, there is a cost reduction effect beyond the increase in the unit price of shaped steel. Furthermore, it will also contribute to the alleviation of the issue of sunshine right with the neighborhood. Further, since the floor structure using the shaped steel of the present invention has improved cross-sectional performance in both X and Y axis directions, the safety of the building against external force such as seismic force is improved. Further, in the floor structure using the shaped steel of the present invention, since the portion located above the middle flange portion of the shaped steel is embedded in the floor member, the portion exposed to the flame from below is reduced accordingly. Therefore, the fireproof coating cost is reduced.
