この発明はフラツトスラブと型枠コンクリート
ブロツクを使用した耐震壁との組合せに係る鉄筋
コンクリート構造の建築物の構築法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a building with a reinforced concrete structure, which is a combination of a flat slab and a shear wall using a formwork concrete block.
フラツトスラブ構造の床構造は梁がないので、

の周囲の柱、梁の型枠、鉄筋作業の省力化が要望
され、その要望の達成によつてフラツトスラブ構
造の効果の増大が期待できる。 Since the floor structure of flat slab structure has no beams,
It can save labor in formwork work and reinforcing bar work. However, flat slab structures require shear walls around the core or around the core to cope with seismic stress. Therefore, the shear wall has a larger amount of wall than a column and beam structure. Therefore, there is a demand for labor-saving work on the shear wall and the columns, beam formwork, and reinforcing bars around the shear wall, and by achieving this demand, it is expected that the effectiveness of the flat slab structure will be increased.

ことができる。 The building in which the construction method of this invention is implemented is a multi-story building with a reinforced concrete structure, with one column and two beams on the outer periphery.
and a seismic wall 3, and in some cases, a seismic wall 3' is also arranged in the core part. Inside the building are multiple pillars 4
A flat slab 5 is provided which is supported by. The earthquake-resistant wall 3 is constructed by placing opposing formwork blocks 6 made of precast concrete, which serve as surface plates, at intervals or with the insides hollow, and reinforcing bars 7 are arranged inside, and concrete is poured. Formwork blocks can also be used for the columns 1, beams 2 and 4, and square steel pipes can be used for the columns 1 and 4 as permanent formwork.

筋してある。 Flat slab 5 uses a large movable formwork, on which floor reinforcement is placed, unbonded PC steel wire is placed, and concrete is poured. After the concrete has hardened, the unbonded PC steel wire 8 is tensed with jacks to introduce tension. The unbonded PC steel wires 8 are arranged densely in the column row zone and sparsely in the intercolumn zone in the X and Y2 directions, in accordance with the bending moment. They are placed close together to form a hanging shape. Inside this concrete slab 5, upper and lower main reinforcing bars 9 are arranged as floor reinforcement.

る。 The in-plane compression force and upward suspension force generated by tensioning the unbonded PC steel wire 8 contribute to the bending moment and shear force in addition to the action of the main reinforcing bar 9, improving the strength and preventing the occurrence of deflection. It can be prevented.

うるようにすることができる。 This invention has the above-mentioned configuration, and a shear wall is arranged around a flat slab structure with few columns and no beams, and the shear wall is constructed using formwork concrete blocks, making construction quick and easy. Floor reinforcement and unbonded PC are placed on the floor formwork.
Since concrete is poured after placing the steel wires, it is possible to economically construct a flat slab structure.
