Description

[Technical field]

[0001] The present invention relates to a building made of reinforced concrete. [Background technology]

[0002] In buildings with two or more floors, such as reinforced concrete apartment buildings and office buildings, some have a pilotis, an open-air space on the first floor (ground level) with no walls and only columns.

[0003] Various structures have been proposed for buildings with pilotis in the past, but one example related to the present invention is the "building with pilotis floor" described in Patent Document 1.

[0004] This "building with a piloti floor" is a building having an upper floor of a rigid frame structure consisting of multiple floors and beams and columns, and a lower floor, a piloti floor consisting of one or more floors, characterized in that it has structural support means erected at both ends of at least one side of the piloti floor, structural beams connecting the upper ends of the structural support means, a structural hanging wall hanging from the structural beam vertically below the area between both ends of at least two upper floor columns positioned horizontally and spaced apart from any of the structural support means, and structural center columns which are fewer in number than the at least two upper floor columns and can be joined at any position of the lower end of the structural hanging wall and extend from the lower end of the structural hanging wall to the lower end of the piloti floor.

[0005] Furthermore, this "building with pilotis floors" has the advantage that it is possible to reduce the number of structural columns on the pilotis floors, while at the same time allowing freedom in the positioning of the structural columns on the pilotis floors.

[0006] [Patent Document 1] JP 2006-328760 A Summary of the Invention [Problem to be solved by the invention]

[0007] As mentioned above, the "building with pilotis floor" described in Patent Document 1 has the advantage that it is possible to reduce the number of structural columns on the pilotis floor and to allow freedom in the positioning of the structural columns on the pilotis floor.

[0008] However, it is undeniable that buildings with pilotis generally lack strength and earthquake resistance compared to buildings without pilotis.

[0009] Therefore, the problem that the present invention aims to solve is to improve the strength and earthquake resistance of buildings equipped with pilotis. [Means for solving the problem]

[0010] The reinforced concrete building of the present invention is characterized in that it comprises an exterior column erected at a position away from at least one column that constitutes a pilotis outside the pilotis, an exterior beam connecting the column and the exterior column and spanning the horizontal direction, and an external load-bearing wall provided in the area surrounded by the exterior column, the column, and the exterior beam. Effect of the Invention

[0011] The present invention makes it possible to improve the strength and earthquake resistance of buildings equipped with pilotis. [Brief description of the drawings]

[0013] Hereinafter, a reinforced concrete building 100 according to an embodiment of the present invention will be described with reference to Figs. 1 to 5.

[0014] As shown in Figures 1 and 2, the reinforced concrete building 100 of this embodiment includes multiple columns 1a, 1b, 1c, 1d, 1e, and 1f erected vertically, beams 2 horizontally connecting adjacent columns among the columns 1a, 1b, 1c, 1d, 1e, and 1f in the directions of the arrows X and Y, and a pilotis P, which is an open-ceiling space surrounded by the multiple columns 1.

[0015] Of the multiple columns 1a to 1f that make up the piloti P, a partition wall 3a is erected between adjacent columns 1e, 1f that are horizontally arranged along the direction of arrow Y on the left side of the building 100, and an internal load-bearing wall 4a is provided between one of the columns 1e, 1f, 1e located on the front side of the building 100, and the partition wall 3a.

[0016] In addition, a partition wall 3b is erected between adjacent columns 1b, 1c horizontally along the direction of arrow Y on the right side of the building 100, and an internal load-bearing wall 4b is provided between one of the columns 1b, 1c, which is located on the front side of the building 100, and the partition wall 3b.

[0017] Stud 3a is erected at a position closer to the front of building 100 than the midpoint between pillars 1e and 1f, and partition 3b is erected at a position closer to the front of building 100 than the midpoint between pillars 1b and 1c, but this does not limit the positions of partition 3a and 3b.

[0018] The building 100 also includes an outer column 5 erected at a position away from one column 1d located at the front of the building 100, out of the multiple columns 1a, 1b, 1c, 1d, 1e, and 1f that make up the piloti P, outside the piloti P, an outer beam 2h that connects the column 1d and the outer column 5 and is suspended horizontally, and an external load-bearing wall 7 provided in the area surrounded by the outer column 5, the column 1d, and the outer beam 2h.

[0019] As shown in Figure 2, the space between stud 3a and column 1e is blocked by internal load-bearing wall 4a, and the space between stud 3b and column 1c is blocked by internal load-bearing wall 4b. However, the spaces between stud 3a and column 1f, and between stud 3b and column 1b are each unobstructed horizontal open spaces, so pilotis P can maintain its original function as a pilotis.

[0020] As explained based on Figures 1 to 5, building 100 has an internal load-bearing wall 4a between stud 3a and column 1e, and an internal load-bearing wall 4b between stud 3b and column 1c, so that it is stronger and has better earthquake resistance than conventional buildings with pilotis.

[0021] In addition, as shown in Figures 1, 2, and 5, the building 100 is equipped with an external load-bearing wall 7 provided in an area surrounded by the outer columns 5, columns 1d, and outer beams 2h, which is effective in improving strength and earthquake resistance.

[0022] Furthermore, compared to a conventional building with a pilotis, the earthquake resistance of the first floor of the building 100 is improved, which has the advantage that deformation of the building (building 100) is reduced.

[0023] It should be noted that the building 100 described with reference to FIGS. 1 to 5 is merely one 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. [Industrial Applicability]

[0024] The building according to the present invention can be widely used in industrial fields such as the civil engineering and construction industry as buildings such as apartment buildings and office buildings made of reinforced concrete. [Explanation of symbols]
