これを第２図ａ，ｂで説明する。 This will be explained with reference to FIGS. 2a and 2b.

によらねばならない。``Problems to be Solved by the Invention'' With the conventional structures mentioned above, the recent trend is that due to the rising cost of factory land and the difficulty in acquiring it, it is necessary to make buildings multi-layered and secure the total floor area. The problem is that there is no flexibility in terms of space or plan, the cost is relatively high, and it is difficult to shorten the construction period.
That is, in the conventional structure, in order to secure a large effective working space, it is necessary to either raise the floor height or reduce the truss structure by inserting columns between the pillars.
しかし、階高を上げると建物全体が大きくなり
建設費が高くなり、又、中間に柱を入れるとクリ

計画上の融通性が損なわれるという難点がある。 However, raising the floor height increases the size of the entire building and increases construction costs, and adding pillars in the middle restricts the layout of the clean room, impairing flexibility in terms of space or floor plan.

提供することを目的としている。 The present invention reduces the weight of the steel frame of the truss frame, increases its rigidity, and makes effective use of the space within the truss frame, so that the beam frame, the frame floor surface, and the free access floor can be connected without inserting columns in between. Achieving a significant reduction in slab formation consisting of
The object of the present invention is to provide a vibration-proof floor structure that supports a free access floor that can constitute a large effective work space.

間をダクトスペースとしたものである。"Means for Solving the Problems" In order to achieve the above object, in the vibration-proof floor structure supporting the free access floor of the present invention, the lower flange of the lower chord of the truss beam installed between the columns is made of SRC. At the same time, a small beam truss is installed orthogonally connected to the truss beam, a stay is brought out from the truss beam, the small beam truss is supported, and the beam frame supporting these trusses is used as a reverse beam to rest on the lower chord of the truss beam. The floor surface of the frame is laid on the upper surface of the beam structure, and a free access floor surface is laid on the upper surface of the beam structure, and the space inside the beam structure is used as a duct space.
「作用」

を持ち出しされて支持される小梁トラスは高剛性
となると共に鉄骨重量が低減される。"Function" In the vibration-proof floor structure configured as above, the truss beam, which is the main beam, has a lower flange of the lower chord.
Since it is constructed with SRC construction, the truss has a reduced steel frame weight and high rigidity, and the small beam truss, which is supported by the stays brought out from the main beam side, has high rigidity and reduces the steel frame weight.
さらには、叙上のステイ持ち出しは大梁のトラ
ス梁にとつては座屈補剛となる。 Furthermore, the above-mentioned stay corral serves as buckling stiffening for the truss beam of the girder.
しかして、トラス架構としては重量増大化を伴
なうことなくして著しく剛性を高められる。 Therefore, the rigidity of the truss frame can be significantly increased without increasing the weight.
さらに、いままで利用せずにデツドスペースで

る。 Furthermore, since the space inside the truss frame, which had been unused and was a dead space until now, was to be used as duct space, the size of the slab consisting of the beam frame, the frame floor, and the free access floor became significantly smaller, requiring a large amount of work. Effective space can be secured.
「実施例」
以下これを実施例図にもとづいて詳細に説明す

成される。 In the figure, 11 indicates a steel column, and 12 indicates a truss beam (large beam), and an access floor surface 13 is laid in contact with the top of the truss beam 12. For the small beam truss 14 that connects to the truss beam 12, as shown in Figure b, the stay 1 is lowered from the upper chord member 12a of the truss beam 12.
A 5 is rolled and supported. The frame floor surface 16 is constructed by laying a deck plate 17 on the lower chord member 12b of the truss beam 12 and pouring slab concrete 18. In other words, the truss beam 12 is a reverse beam. Further, the lower flange of the lower chord member 12b of the truss beam 12 is covered with concrete 19 to form SRC.

上をなしつつ大スパンの耐震架構となる。 Therefore, in the floor structure of the present invention, as described above, the truss beam 12 has the lower flange of the lower chord member 12b.
Because it is made of SRC, the neutral axis of the lower chord is lowered, increasing the rigidity of the entire truss, which has a large vibration-proofing effect.
In addition, the rigidity can be easily changed by changing the cross section of the SRC section, making it easy to control the natural frequency, reducing the weight of the steel frame and improving the rigidity of the truss, while creating a large-span earthquake-resistant structure.

１２の座屈補剛の効果を達成している。 Further, since the small beams 14 are supported by the stays 15 which serve as tension members, the rigidity is increased and the weight of the steel frame is reduced. Moreover, since it is located above the floor surface 16 of the building frame, the members become smaller and the ceiling space is freed up. On the other hand, the stay 15 achieves the effect of buckling and stiffening the truss beam 12.

有する。 In the present invention, since the upper chord member 12a of the truss beam 12 is raised to the free access floor surface 13, a large space can be constructed with the already mentioned large span earthquake-resistant frame without increasing the floor height of the building. The horizontal force of the free access floor surface 13 can be handled by the truss beam 12, improving earthquake resistance, and there is no beam at all within the ceiling surface 20, which is composed of a suspended structure. , ducts can be freely swung around, making it possible to create a highly flexible space in terms of equipment functionality, and the area below the free access floor surface 13 can be freely accessed between diagonal members of the truss. have
