にしているものがある。(Prior Art) Conventionally, for example, as shown in FIG. 7, a heavy-duty warehouse with multiple floors has a steel-framed reinforced concrete structure on the first floor and an unbonded flat slab type reinforced concrete structure on the upper floor.
In some cases, the floor slab S on the upper floor is constructed by a conventional method in which beams B and B1 are projected below the slab, and the floor slab Sa on the upper floor is a flat slab.
（考案が解決しようとする課題） この従来例によると、２階の床スラブＳはスラブ下方に
縦横に配設してある梁B,B1が突出しているため、この梁

にある。(Means for Solving the Problem) The feature of the present invention is that the floor has a flat slab 2 structure with a flat beam, and between the pillars 5 in one direction, only the PC steel wire 31 is concentrated within the flat slab thickness. A centralized wiring portion 3 is arranged, and a flat beam 4 containing a steel frame 41 and having the same thickness as the capital 6 is provided between columns 5 in the other direction orthogonal to the above direction.

る。(Operation) The flat beam 4 has an effect of suppressing reduction in seismic resistance in the direction intersecting with the concentrated wiring portion 3. The flat beam 4 is
Unlike the concentrated wiring part 3 in which PC steel wires are concentrated, it can resist repeated forces during an earthquake, so it is more effective when applied in the direction in which horizontal resistance is required (for example, there is no bearing wall).
（実施例） 第１図において、建物１は、１階をSRC造で施工し、上

特徴を示す偏平梁付きフラットスラブ２としてある。(Example) In Fig. 1, in the building 1, the first floor is constructed by SRC construction, the upper floor is constructed in the same manner as the conventional example, and the floor on the second floor is flat with flat beams showing the features of the present invention. It is as Slab 2.
ここで、偏平梁付きフラットスラブ２の具体的構造を、
第２〜５図を参照して説明する。Here, the specific structure of the flat slab 2 with flat beams is
This will be described with reference to FIGS.

タル６の厚さと等しくなっている。Within the thickness of the flat slab 2 with flat beams, the central wiring portions 3 are provided between the pillars 5 in one direction (vertical direction in FIG. 2).
A flat beam 4 is provided between columns 5 in the other direction orthogonal to the wiring portion, and the flat beam formation is equal to the thickness of the capital 6 formed on the head of the column 5.

た複数のPC鋼線31,…からなる。The centralized wiring section 3 has pillars 5 that are orthogonal to the respective capitals 6.
It is arranged for each span of ... And consists of a plurality of PC steel wires 31, ... Wired in parallel in one direction.
他方向の偏平梁４は、第3,4図に示すように梁内部にＨ
形鋼梁鉄骨41を配設してあり、これはキャピタル６内で
Ｈ形鋼柱鉄骨51と直交している。The flat beam 4 in the other direction is H inside the beam as shown in Figs.
A shaped steel beam steel frame 41 is provided, which is orthogonal to the H-shaped steel column steel frame 51 in the capital 6.
キャピタル６内には、第3,5図に示すように柱鉄骨51に

レートに代えてアングルでもよい。As shown in FIGS. 3 and 5, the H-shaped steel reinforcing steel frame 7 is formed in the capital 6 so as to be orthogonal to the beam steel frame 41 with respect to the column steel frame 51.
Is provided. Only the upper flange 71 of the reinforcing steel frame is passed through the slab 2 along the wiring direction of the concentrated wiring portion 3,
This is used for steel frame construction. An angle may be used instead of the plate that is the flange.
また、偏平梁４と平行に等間隔に配設したPC鋼線８があ
る。Further, there are PC steel wires 8 arranged at equal intervals in parallel with the flat beam 4.
上例では、柱５の頭部付近に鉄骨41,7が位置しているた
め、パンチング耐力を増大させることができる。In the above example, since the steel frames 41, 7 are located near the head of the column 5, the punching resistance can be increased.
