Abstract

An open living space is obtained by providing necessary strength without providing a structural member that protrudes from a ceiling or a floor in an opening.
The width of the beam 1 at the opening of the building is larger than the width of the pillar 2 and extends in the slab direction, and the beam 1 constitutes the floor surface of the balcony 5. The beam is almost equal to the distance between the ceiling surface and the floor surface of the living room, and there is no protrusion from the living room toward the opening 4 so that a large opening is formed, and a living room with a feeling of opening is obtained. Moreover, since a glass handrail or a vertical handrail can be adopted for the balcony 5, the view from the living room is open, and an open living room can be provided, and the balcony 5 has a deep depth. can do.

Description

  The present invention relates to a reinforced concrete structure, or a steel reinforced concrete structure and a steel structure building, which is excellent in daylighting and ventilation without providing a projecting member at the opening, and provides a sense of openness to residents. .

  Traditionally, reinforced concrete structures, steel reinforced concrete structures, and steel-framed buildings generally have a rigid frame structure consisting of columns and beams. However, to obtain the required strength, the beam formation is relatively large. There is a problem that it protrudes indoors and the height of the opening is limited, so that the opening cannot be made large, lacking in openness, and insufficient lighting and ventilation.

In order to solve such a problem, an inverted beam structure or a flat slab structure shown in FIG. 4 has been proposed. The reverse beam construction method can adopt a high sash and can take a large lighting surface, but when the beam is placed outside the balcony, it is used as the outer fence of the balcony, so the outer fence is made of reinforced concrete. It is a fence that blocks the field of view, and because it is a structural member, it is thick and the depth of the balcony is narrowed.
The flat slab is also used as a beam that bears a horizontal force, and the entire surface of the floor must be considerably thick.

Patent Document 1 (Japanese Patent Publication No. 4-28064) discloses a ramen-structured core and a short-span ramen that surrounds it as an improvement in aesthetics without providing a protruding member in the living space and an increased degree of freedom in floor plan. According to the structure, a flat space without a pillar is obtained, and in Patent Document 2 (Japanese Patent Laid-Open No. 2002-121924), a high-rigidity core reinforcing structure composed of a seismic wall is provided at the center of a building as an apartment building. It has been proposed to provide a slab that protrudes around the reinforcement structure and supports the slab, but in any case, a beam that receives the slab is required on the outer periphery of the building, so a large opening is obtained. I couldn't. (See Figure 5)

  An object of the present invention is to provide a necessary strength as a structure without providing a structural member having a large cross section that protrudes from a ceiling or a floor in an opening, and there is no feeling of pressure and an open living space. Is to be able to build.

In buildings with columns and beams, the floor height is increased by making the width of the beam at the opening larger than the width of the column and making the width of the beam that intersects the beam at the opening equal to or less than the width of the column. This makes it possible to obtain a large open room with no opening.
Further, by using this beam as a floor surface of a balcony, a glass handrail or the like can be adopted, and a feeling of opening is further provided.
In addition, the strength of the structure is to be borne by multiple floors, and the beams on each floor are smaller than the beams on the upper and lower floors. The overall height is reduced to reduce costs.

The present invention will be described based on examples.
Example 1
As shown in FIG. 1, the building of the present invention has a reinforced concrete structure or a steel reinforced concrete structure, and is a type in which a balcony 5 is provided. This embodiment assumes up to about 15 stories, but can also be applied to buildings with more than that.

The pillar 2 has a cross section of 1000 (b) × 1000 (mm) and a span of 6 to 8 m. The beam 1 of the opening 4 has a cross section of 1400 (B) × 600 (mm), has a width larger than the width of the pillar, and extends toward the living room side so as to constitute the floor surface of the balcony 5. . In addition, since the beam is placed between the ceiling surface and the floor surface, there is no protrusion from the living room toward the opening 4, and a large opening is obtained compared to the conventional case, and there is a feeling of opening. It can be a living room.
As shown in FIG. 2, the beam 11 that intersects the beam of the opening 4 is 600 × 900 (mm), and the thickness of the slab 3 is 200 to 250 (mm), which is the same as a normal residential building. It is.

The floor surface of the balcony 5 provided outside the opening 4 is composed of a beam 1, and an inclined surface directed inward is formed on the upper surface of the beam 1 to drain rainwater and the like. A drain groove 51 is provided at the end of the slope.
According to the present invention, a high sash having a height of about 2400 mm can be installed in the opening 4 as in the case of using a reverse beam. In addition, when the reverse beam is provided on the balcony portion, the beam blocks the field of view. However, in the present invention, a glass handrail or a vertical handrail can be adopted as in the case of the forward beam, so the field of view can be adopted. It can be opened without any obstacles, and it can be an open room, and the balcony can be deep.

Example 2
The example shown in FIG. 3 is a case where a balcony is not provided, and the basic structure is the same as the case where the balcony of Example 1 is provided.
The pillar 2 has a cross section of 1000 × 1000 (mm), and the basic cross section of the beam 1 is 1400 × 600 (mm). The cost is reduced by suppressing the height from increasing.

  In the openings of reinforced concrete structures or steel-framed reinforced concrete structures and steel buildings, the beam strength is suppressed by making the beam width larger than the column width, and the required strength as a structure without providing a member protruding in the opening Can be obtained, and a large opening can be set, so that the degree of freedom of the floor plan increases and the occupant can feel open.
