Description

The present invention relates to a reinforced concrete building.

The structures of buildings such as reinforced concrete housing complexes and office buildings can be divided into two types: rigid-frame structures and wall structures.

Rahmen structures support buildings with a frame formed by vertical columns and horizontal beams that connect the columns. be able to. In addition, the Rahmen structure does not form immovable load-bearing walls in the interior of the building, so it has the advantage of making it easy to create a free space. . However, in a rigid-frame structure building, there is a demerit that the pillars and beams protrude into the room.

On the other hand, the wall-type structure is a structure in which a space is formed by a total of six walls including a floor, a ceiling and four walls, and is often constructed in buildings of five stories or less. In wall-type structures, rather than using columns and beams, the building is supported by flat walls, so the interior space becomes a clean space with no unevenness, making it easy to arrange furniture, and it also has the advantage of being strong against earthquakes. be.

However, since the walls that support the building cannot be removed in the wall-type structure, there is a demerit that the degree of freedom in changing the floor plan when renovating in the future is lower than in the Rahmen structure. In addition, since the wall-type structure has a larger self weight than the Rahmen structure, it is not suitable for high-rise buildings. In addition, when building a building of six stories or more with a wall structure, it is necessary to calculate the ultimate strength, which not only requires a lot of labor and time, but also requires examination by a special confirmation agency. Therefore, the review period tends to be longer.

As described above, conventionally, various improvement techniques have been proposed for buildings with rigid-frame structures that have various advantages and disadvantages. There is a wall frame frame.

This wall-type Rahmen frame creates a wide living space with a pair of girder-direction load-bearing walls arranged in parallel and long span-direction load-bearing walls installed between the facing wall pillars of the girder-direction load-bearing walls. Along with demarcating, the girder direction bearing walls are placed side by side in parallel with formation intervals such as corridors or balconies outside the girder direction bearing walls, and between each girder direction bearing wall and each span direction bearing wall part of the living space It is characterized in that it is constructed by arranging each floor slab for corridors, balconies, and the like.

JP-A-5-247997

In conventional Rahmen-structured buildings, some of the pillars and beams protrude into the interior of the room, which often interferes with the placement of furniture, cupboards, and other items. It is an impeding factor.

On the other hand, the wall-type Rahmen frame structure described in Patent Document 1 can form a wide living space without wall pillars or wall beams exposed in the room, and the frame bearing strength is increased, which is useful for partition planning, hotels, offices. It has the advantage of increasing the degree of freedom in changing buildings, etc., and making it possible to build high-rise buildings.

However, in the wall-type Rahmen frame structure described in Patent Document 1, as shown in [Fig. Since the girder-direction load-bearing walls 1 are arranged in parallel with the space between the slabs 4 or the floor slabs 5 such as verandas, the structure is complicated, which may impose restrictions on the design. In addition, since the wall pillars 1a are provided only in the girder direction load-bearing wall 1, there are areas where the earthquake resistance is not sufficient.

Therefore, the problem to be solved by the present invention is to be able to be constructed widely from low-rise buildings to high-rise buildings, to prevent columns and beams from appearing in the room, to have excellent earthquake resistance, and to reduce the amount of concrete used. It is to provide a building that can

A building according to the present invention is a reinforced concrete building comprising a plurality of vertically erected pillars and a beam extending horizontally by connecting the pillars,
a girder direction load-bearing wall formed integrally with the pillar between the pillars adjacent in the girder direction in the pillars forming an outer wall portion parallel to the girder direction;
a wall pillar erected at a position closer to one of the pillars between the pillars facing each other in the span direction in the pillars forming the outer wall portion parallel to the girder direction, and the pillar and the wall pillar a cross-beam direction load-bearing wall integrally formed with the pillar and the wall pillar,
A column width in the girder direction of the column and the wall column and a wall thickness of the inter-beam direction load-bearing wall are equal to each other.
In addition, the above-mentioned "equivalent" does not mean that it is "equivalent" in terms of high dimensional accuracy standards of about μm, but dimensional accuracy adopted in the fields of civil engineering construction industry and civil engineering construction industry It means "the same, equal" in the standard.

In the building, the beam width of the beam can be made equal to the wall thickness of the inter-beam direction load-bearing wall.

To provide a building which can be widely constructed from a low-rise building to a high-rise building, has no pillars or beams inside the building, has excellent earthquake resistance, and can reduce the amount of concrete used. can be done.

As shown in FIGS. 1 to 5, a building 100 according to the present embodiment includes a plurality of columns 1 erected in the vertical direction and columns 1, 1 adjacent to each other in the direction Y between the beams. and a beam 4 which connects the pillars 1 and 1 adjacent to each other in the girder direction X and spans them in the horizontal direction.

As shown in FIGS. 2 and 3, among a plurality of pillars 1 forming an outer wall portion 5 (see FIG. 1) parallel to the girder direction X, between the pillars 1, 1 adjacent to each other in the girder direction X, the pillars 1, 1 A longitudinal load-bearing wall 6 is formed integrally with 1 .

As shown in FIGS. 3 to 5, in a plurality of columns 1 forming the outer wall 5 parallel to the girder direction X, between the columns 1 adjacent to each other in the span direction Y, at a position near each column 1 A wall pillar 7 is erected, and an inter-beam direction bearing wall 8 is formed integrally with the pillar 1 and the wall pillar 7 between the pillar 1 and the wall pillar 7 . As shown in FIG. 1, the width 2w of the beam 2, the width 1w of the column 1, the width 7w of the wall pillar 7, and the wall thickness 8t of the bearing wall 8 in the inter-beam direction are the same.

Therefore, the wall type described in Patent Document 1 The earthquake resistance is greatly improved compared to the Rahmen frame.

As shown in FIG. 1, in the building 100, since the load on the beam 2 is reduced, the width 2w of the beam can be reduced, and the thickness 8t of the wall can also be reduced. can be reduced.

As shown in FIGS. 1, 3, and 4, in the building 100, the pillar 1, the wall pillar 7, and the beams 2 and 4 do not partially protrude into the room, so that a wide living space can be secured, and furniture can be installed. Space can be effectively used when placing a cupboard or the like.

As described above, the building 100 can reduce the stress load on the beams 2 and 4 by improving the earthquake resistance performance, so that the beam height can be suppressed and the floor height can be designed to be low. Further, as shown in FIGS. 1 to 3, by securing the beam width 3w of the beam 3 larger than the column width 1w of the column 1, the wall thickness 8t of the inter-beam direction bearing wall 8 can be reduced.
