る。2. Description of the Related Art In a conventional wall-type reinforced concrete structure with no columns, a frame is composed of a wall, a floor, and a beam.
The beam that protrudes into the room is a hindrance in space. Further, in the conventional wall-type reinforced concrete structure, a constant wall amount is required in both the X and Y directions, which is spatially limited.

して許容している。[0003] In a conventional wall-type rigid frame type reinforced concrete structure, the frame is composed of columns, beams and small beams, and floors and walls. The columns, beams, small beams, floor and walls are protected against long-term vertical loads. While it is designed to work, columns, beams and walls are designed to work against earthquakes, but are wasteful in terms of material. Also, the pillars, girders, and girders protrude into the room, which hinders space. In addition, with conventional reinforced concrete structures,
Shear and bending cracks are likely to occur on walls, columns and beams during an earthquake. The design criteria allow for cracks.

る。In this wall-type rigid frame structure, the columns, beams, and small beams protruding into the room not only hinder the securing of a wide free space in the room, but also complicate the outer shape of the frame. Formwork and reinforcement work are not easy, which causes cost increase. In addition, since the presence of beams increases the floor height by that amount, when building an apartment house on a site with height restrictions, it becomes a factor that restricts the maximum number of floors.

い。[0010] In the present invention, the floor formed by wrapping the plurality of reinforcing bars for floors arranged and arranged as described above with cast concrete forms a plurality of densely arranged wide cross sections. Is formed in a cross-sectional structure in which the beam members are integrally incorporated. In other words, this floor is equivalent to a beam having a wide cross section continuously and repeatedly arranged in the depth direction. Further, a wall formed by wrapping a plurality of reinforcing steel cages for walls arranged and arranged as described above with cast concrete is composed of a plurality of densely arranged pillar members having a wide cross section. The cross-sectional structure is included in the combined state. In other words, this wall corresponds to a column in which columns having a wide cross section are repeatedly arranged continuously in the depth direction. Thus, the floor will also have the function of a beam and the wall will also have the function of a column. As a result, necessary and sufficient earthquake resistance is secured in the longitudinal direction as a rigid frame structure and in the short side direction as a conventional wall type structure.
In addition, sound insulation is improved by casting concrete to a thickness of 25 cm to 35 cm. Thus, the floor / wall type reinforced concrete structure without beams of the present invention is composed of floors and walls, and the floors and walls support long-term vertical loads, and function as earthquake-resistant members during an earthquake. The number of types of members is smaller than that of the conventional structure using beams and small beams, and there is no waste.

3, the floor 1 functions as a conventional structural member that also serves as a beam and a floor, while the wall 7 functions as a conventional structural member that also serves as a column and a wall. The pillars and beams protruding into the room can be omitted altogether, and a wide and free space without unevenness can be secured. Since there are no columns and beams, the windows for daylighting can be provided over the entire width and height of the floor if desired.

Has a sufficient and sufficient seismic strength as a ramen structure, and unlike conventional wall-type structures, there is no need to add a bearing wall for seismic reinforcement at right angles to the wall.

ため、型枠費の削減が可能である。The reinforced concrete structure of the present invention comprises only the floor 1 and the wall 7, and the structure of the floor 1 and the wall 7 itself is also simple, so that the mold for forming the floor and the wall is also simplified. Since the formwork can be standardized and the diversion width of the formwork can be increased, the formwork cost can be reduced.

圧縮が可能である。Further, as described above, the floor is a repetition of the reinforcement of the beams, and the wall is a repetition of the reinforcement of the columns. Therefore, the reinforcement of the floor and the wall is simplified, and the pre-assembly method of the rebar is appropriately used. Since it can be selected, the rebar assembly cost can be reduced. Due to the simplification, it is not necessary to arrange skilled technicians for rebar assembly, and relatively low-wage unskilled technicians are sufficient, so that labor costs can be reduced. In the reinforced concrete structure of the present invention, it is possible to reduce the overall construction cost by reducing the labor cost in the above-described formwork and reinforcing steel work.

向（奥行き方向）は厚目の壁があるため、壁量、壁率が
通常の鉄筋コンクリート造よりも高い。そのため、地震
に強く、壁方向はせん断ひび割れが発生しにくい構造と
なっている。In the reinforced concrete structure of the present invention, since there is a thick wall in the wall direction (depth direction), the wall amount and the wall ratio are higher than those of a normal reinforced concrete structure. For this reason, the structure is resistant to earthquakes and hardly generates shear cracks in the wall direction.

No shear cracks occur,
Utilizing the fact that cracks are easily concentrated on the wall and floor edges,
By including a crack-inducing joint in this part, it is possible to minimize crack damage during a small or medium-sized earthquake.
