Description

The present invention relates to a building made of reinforced concrete.

In buildings with two or more floors, such as reinforced concrete housing complexes and office buildings, the first floor (above ground) is equipped with a piloti, which is an atrium space with no walls and only columns. There is.

Regarding buildings with pilotis, various structures have been proposed in the past, but one related to the present invention is, for example, the "building with piloti floors" described in Patent Document 1. There is.

This "building with piloti floors" is a building with a multi-story rigid frame structure consisting of beams and columns, and a piloti floor, which is the lower floor, and consists of one or more floors. between the ends of at least two upper floor columns located in the horizontal direction; A structural hanging wall depending vertically below the area from a structural beam and spaced apart from any structural support means; The structure is characterized by having a structural column that can be joined to the structural wall and extends from the lower end of the structural hanging wall to the lower end of the piloti floor.

This "building with piloti floors" has the advantage that it is possible to reduce the number of structural columns on the piloti floors, and at the same time, it is possible to give a degree of freedom to the position of the structural columns on the piloti floors.

As mentioned above, the "building with piloti floors" described in Patent Document 1 has the advantage that it is possible to reduce the number of structural columns on the piloti floors and to provide flexibility in the position of the structural columns on the piloti floors. It is equipped with

However, it is undeniable that buildings with pilotis generally lack strength and earthquake resistance compared to buildings without pilotis.

Therefore, the problem to be solved by the present invention is to improve the strength and earthquake resistance of buildings equipped with pilotis.

A first building according to the present invention includes a plurality of vertically erected columns, a beam connecting the columns and extending horizontally, and an atrium space surrounded by the plurality of columns. A reinforced concrete building with pilotis,
A stud installed between horizontally adjacent pillars among the plurality of pillars constituting the piloti, and between one of the horizontally adjacent pillars and the stud. An internal load-bearing wall is provided.

A second building according to the present invention includes a plurality of vertically erected columns, a beam connecting the columns and extending horizontally, and an atrium space surrounded by the plurality of columns. A reinforced concrete building with pilotis,
an outer pillar erected at a position apart from at least one pillar constituting the piloti on the outside of the piloti; an outer beam connected horizontally to the pillar and the outer pillar; The present invention is characterized by comprising a column, and an external load-bearing wall provided in an area surrounded by the column and the outer beam.

According to the present invention, the strength and earthquake resistance of buildings equipped with pilotis can be improved.

FIG. 3 is a partially omitted vertical sectional view taken along line BB in FIG. 2. FIG. 3 is a partially omitted vertical sectional view taken along line CC in FIG. 2. FIG. 3 is a partially omitted vertical sectional view taken along line DD in FIG. 2. FIG.

Hereinafter, a reinforced concrete building 100, which is an embodiment of the present invention, will be described based on FIGS. 1 to 5.

As shown in FIGS. 1 and 2, a reinforced concrete building 100 according to the present embodiment includes a plurality of columns 1a, 1b, 1c, 1d, 1e, 1f vertically erected, and columns 1a, 1b. , 1c, 1d, 1e, and 1f, a piloti is an atrium space surrounded by a beam 2 that is hung horizontally by connecting adjacent columns in the X and Y directions of the arrows, and a plurality of columns 1. It is equipped with P.

Among the plurality of columns 1a to 1f that constitute the piloti P, a stud 3a is erected between the columns 1e and 1f that are horizontally adjacent to each other along the arrow Y direction on the left side of the building 100, and the column 1e , 1f, an internal load-bearing wall 4a is provided between one pillar 1e located on the front side of the building 100 and a stud 3a.

Furthermore, a stud 3b is erected between the columns 1b and 1c that are horizontally adjacent to each other along the arrow Y direction on the right side of the building 100, and a stud 3b is located on the front side of the building 100 among the columns 1b and 1c. An internal load-bearing wall 4b is provided between one of the pillars 1c and the stud 3b.

The stud 3a is erected at a position closer to the front of the building 100 than the intermediate position between the columns 1e and 1f, and the stud 3b is erected at a position closer to the front of the building 100 than the intermediate position between the columns 1b and 1c. However, the positions of the studs 3a and 3b are not limited.

Furthermore, the building 100 is located outside of the piloti P from one pillar 1d located in front of the building 100 among the plurality of pillars 1a, 1b, 1c, 1d, 1e, and 1f that constitute the piloti P. The external pillar 5 is erected at the position, the external beam 2h is horizontally installed by connecting the pillar 1d and the external pillar 5, and the external pillar 5 is provided in the area surrounded by the external pillar 5, the external pillar 1d, and the external beam 2h. An external load-bearing wall 7 is provided.

As shown in FIG. 2, the space between the stud 3a and the column 1e is closed by an internal load-bearing wall 4a, and the space between the stud 3b and the column 1c is closed by an internal load-bearing wall 4b. Since the space between the space and between the stud 3b and the pillar 1b is a horizontal atrium space with no obstructions, the piloti P can maintain its original function.

As described based on FIGS. 1 to 5, the building 100 includes an internal load-bearing wall 4a between the stud 3a and the column 1e, and an internal load-bearing wall 4b between the stud 3b and the column 1c. Because of this, it is stronger and has better earthquake resistance than buildings with conventional pilotis.

In addition, as shown in FIGS. 1, 2, and 5, the building 100 has an external load-bearing wall 7 provided in an area surrounded by the external columns 5, 1d, and external beams 2h, so that the building 100 has a strong and is effective in improving earthquake resistance.

Furthermore, compared to buildings with conventional pilotis, the building 100 has an advantage in that the earthquake resistance of the first floor portion is increased, so that the deformation of the building (building 100) is reduced.

Note that the building 100 described based on FIGS. 1 to 5 is an example of a building according to the present invention, and the building according to the present invention is not limited to the building 100 described above.

The building according to the present invention can be widely used in industrial fields such as the civil engineering construction industry and the civil engineering construction industry as buildings such as reinforced concrete housing complexes and office buildings.
