を貫通させるために、その作業が非常に面倒である。[Prior Art] In the conventional floor construction method of a building, a large beam is installed between columns and a slab is laid on it. According to such a general floor construction method, as shown in FIG. 5 (a), since the girder of the large girder c is large, the floor height is increased to secure a predetermined ceiling height h, and the small girder is assembled. Because of this, the beam form becomes complicated, and the amount of processing of steel frames and reinforcing bars increases, which is a drawback. Further, as shown in FIG. 5B, the pipe d is a beam e.
The work is very cumbersome to penetrate.

There is a "unidirectional rigid frame construction method" in which no large beams are installed on both sides of the building, but in this case as well, further improvements were made in terms of reduction of floor height, facilitation of facility piping work, and labor saving of beams and floor construction. Was desired.

題としたものである。The present invention has been made in order to meet such a demand, and not only eliminates the large beams on both sides of the center column in the girder row passing through the center column, but also improves the span of both sides of the center column in the beam row passing through the center column. Among them, the technical issue is to provide a mixed structure in which a flat slab is introduced by eliminating the large beam on the long span side.

のである。[Means for Solving the Problem] As a means for solving this technical problem, the present invention provides a center 2 with a capital 2 and spans on both sides of the middle pillar 1 in a beam row passing through the middle pillar 1. Short span of L 1
The side is a flat beam 3 composed of a beam whose height is matched with that of the capital 2.
The flat plate slab 4 is attached to the flat pillar slab 4, and the long span L 2 side of the spans on both sides of the center pillar 1 has a flat slab 5 structure without a girder.

る。[Operation] Since the girder size of the large girder can be reduced according to the capital, it is possible to reduce the floor height, and since there is no large girder on the long span side from the center pillar, it is easy to route the equipment piping. Moreover, since the floor structure is simple, it is possible to reduce the amount of materials and labor for construction.
［実施例］ 以下、図示の実施例により本考案を更に詳しく説明す

低くすることが出来る。FIG. 1 is a plan view of a standard floor of a building to which the present invention is applied, in which middle pillars 1 are erected in C-directions in the girder direction, and a capital 2 is provided at each upper end thereof. With the middle pillar 1 as a boundary, flat beams 3 are provided on the short span L 1 side of the beam rows passing through the middle pillar 1, and a flat plate slab 4 is mounted thereon. The flat beam 3 is formed so as to fit the lower surface of the capital 2, and in this case, it can be lowered by about 200 to 500 mm as compared with a normal girder.
一方、前記中柱１を通る梁行におけるスパンのうち長

それぞれピン接合されている。On the other hand, of the spans in the beam row passing through the center pillar 1, the long span L 2 side does not have a large beam unlike the one-way rigid frame, and has a flat slab structure via the capital 2 and its slab 5 The outer ends, that is, the A side, are pin-joined.
このような床構造は、第２図に示すように例えば８階
建てビルの２階から８階迄同様に採用されている。尚、
外壁要所には耐震壁６が取り付けられている。Such a floor structure is similarly adopted, for example, from the second floor to the eighth floor of an 8-story building as shown in FIG. still,
A seismic wall 6 is attached to a key part of the outer wall.

Only the short beams (flat beams) closer to the outer wall (D way) from the middle pillar 1 have beams, and the long beams closer to the outer wall (A way) do not exist. Buildings to which this floor structure can be applied are similar to the one-way frame construction method, that is, the total floor area is
This is for a building with a floor space of 3000 m 2 or more and 9 floors or less, and the condition that a floor plan that allows sufficient seismic resistance on the outer wall in the girder direction is available. Also, it is suitable for buildings with a flat shape and scale so that excessive axial force does not act on the corner posts during an earthquake.

期に亙って良好な品質を保持することが出来る。[Effects of the Invention] As described above, according to the present invention, since a long-span large beam is eliminated, the floor height can be lowered, and piping for passing the beam is not required. It becomes simple and efficient, and the degree of freedom of piping can be increased. Further, unlike the conventional case, it is not necessary to form a form of a large beam and a small beam, so that the frame construction work is easy, and the amount of rebar used is reduced, and labor can be saved. Furthermore, the quality of the building is equal to or better than that of unidirectional ramen, the slab thickness is thicker, and prestress is applied, so that good quality can be maintained for a long period of time.
