Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an apartment house suitable for use as a structure of an apartment house such as an apartment.

2. Description of the Related Art Conventionally, the structure of a plate-shaped apartment house is as follows.
A pair of rigid frame structures extending in the girder direction are arranged in parallel with each other, and a plurality of earthquake-resistant walls (serial walls) extending along the tension direction are provided between the pair of rigid frame structures. (Seismic wall).

[0003]

In a plate-shaped apartment house as described above, the rigidity of the rigid-frame structural structure resists the toughness against seismic force and the like, but the resistance of the multi-story earthquake-resistant wall. To resist. However, in this case, the larger the multi-story building is, the higher the height of the building is, the larger the multi-story shear walls will be, and the structures such as the frame pillars supporting the multi-story shear walls will also be large. Inconvenience that the cost becomes high as well as the obstacle occurs.

[0004] In addition, since such a conventional plate-shaped apartment house has a multi-story earthquake-resistant wall as described above, the horizontal rigidity is relatively large. Therefore, when the building's width-to-height ratio (height / column span) is raised to about 4 (specifically, about 20 stories), the vertical force generated at the foundation of the building due to the overturning moment during an earthquake It becomes too large, and the design of the foundation structure (pile) becomes impossible, or even if possible, it becomes too large, which is inconvenient. There is a method of reducing the above-mentioned width-to-height ratio by increasing the span in the direction, and reducing the vertical force generated on the foundation.However, it is impossible to widen the span due to the site shape, It is not suitable for implementation because it requires time and effort and causes a significant increase in cost.

[0005] In view of the above circumstances, the present invention is advantageous in terms of planning by minimizing the size of a structure such as a pillar in realizing a large and high-rise plate-shaped house, and keeps the cost as low as possible. It is another object of the present invention to provide a multi-family housing structure in which the overturning moment during an earthquake is made as small as possible, thereby making it unnecessary to increase the size of the foundation structure.

The multi-layer earthquake-resistant wall 150 on the other side (on the right side in FIG. 1) is connected to the column 9 on the second frame structure side 30 (that is, the column 9 on the right side in FIG. 1). ,
Each column 9 is a frame column for these multi-story shear walls 150. ). Each multi-story earthquake-resistant wall 150 extends in the directions of arrows C and D, which are installed in upper and lower layers at the predetermined floor height interval H1 and the plurality of earthquake-resistant walls 15 extending in the directions of arrows C and D installed in a line in the vertical direction. Each of the shear walls 15 and each of the frame beams 11 are provided with the multi-story shear walls 15.
0 is directly connected to the column 9 connected thereto (the height position of each frame beam 11 corresponds to the height position of each beam 10 described above). Further, the seismic walls 15 and the frame beams 11 are arranged alternately in the upper and lower directions. Therefore, one frame beam 11 connects the seismic walls 15, 15 between the vertically adjacent seismic walls 15, 15. It is arranged in.
Further, of each of the earthquake-resistant walls 15, the side 15 a connected to the column 9 is connected to the other side 1 facing away in the directions of arrows C and D.
5b is connected to a sub pillar 13 extending vertically.
The upper end and the lower end of the sub pillar 13 are connected to frame beams 11, 11 installed adjacently above and below the earthquake-resistant wall 15. That is, one earthquake-resistant wall 15 is fixed by the columns 9, the frame beams 11, 11, and the sub-columns 13 connected thereto.

Further, columns 9, 9 of the frame structures 20, 30, which are arranged corresponding to each other in the directions of arrows C, D.
Between the multi-story earthquake-resistant walls 150 installed between them, a multi-story opening 160 that is continuous in the vertical direction is formed,
A plurality of boundaries between the multi-story earthquake-resistant walls 150 extend in the directions of arrows C and D across the multi-story opening 160, and are arranged in upper and lower layers at the predetermined floor height interval H1 described above. They are connected by beams 14. That is, the plurality of boundary beams 14 ensure the integrity of the building. Specifically, each of the boundary beams 14 includes one frame beam 11 on one of the multi-story earthquake-resistant walls 150, 150 installed between the columns 9, 9 and the other, and It is provided so as to connect one frame beam 11 on the multi-story earthquake-resistant wall 150 side in the directions of arrows C and D. In other words, each boundary beam 1

0, the earthquake-resistant walls 15, 15 adjacent in the directions of arrows C and D
Each frame beam 11 connected to each of the earthquake-resistant walls 15
Are connected in the directions of the arrows C and D via the. In other words, if the structure composed of the boundary beam 14 and the frame beams 11, 11 connected by the boundary beam 14 is the beam unit 17, between the columns 9, 9 corresponding to each other in the directions of arrows C, D. In this example, a plurality of beam units 17 extending in the directions of arrows C and D are installed in the upper and lower layers at the above-mentioned predetermined floor height interval H1 (note that the boundary beams 14 are provided).
And the frame beams 11, 11 may form one continuous beam member, and therefore the beam unit 17 may be a single seamless beam member. ).

The boundary beam 14 is a steel beam member made of a very mild steel which is a low yield point steel having excellent toughness, that is, a tough steel material 61. The elongation performance of a general building steel material (normal steel material) is about 20% ("elongation performance" means that the length of a steel material in a state where it is not subjected to an external force is L, and a force is applied to the steel material. The length in the state immediately before breaking is L + Δ
L (that is, ΔL is the amount of extension) is represented by the value of ΔL / L. ), The elongation performance of the tough steel material 61 employed in this embodiment is 40% or more. Specifically, as shown in FIG. 10, the boundary beam 14 has a steel frame 62 that is an H-shaped steel,
The web portion of the steel frame 62 is formed of the above-described tough steel material 61, and the flange portion is generally formed of the steel material 60. By adopting a tough steel material 61 for the web portion, the boundary beam 14 is advantageous for shear yielding. In addition, boundary beam 1
The specific configuration of 4 is possible other than that shown in FIG. For example, as shown in FIG.
In the above, the flange portion of the steel frame 62 may be formed of the above-described tough steel material 61, and the web portion may be formed of the normal steel material 60. Thereby, the boundary beam 14 is advantageous for bending and tensile yielding. (Besides, the boundary beam 14 may be a steel-concrete beam member using extremely mild steel.)

In the present embodiment, as shown in FIG. 3, the width W of the frame beam 11 and the boundary beam 14 in the directions of arrows A and B is shown.
1. The width W2 of the sub pillar 13 in the directions of arrows A and B is the width W of the earthquake-resistant wall 15 connected thereto in the directions of arrows A and B.
3 (of course, in another embodiment, the width W
1, W2 and W3 may have different sizes. ).
Thereby, these frame beam 11, boundary beam 14, sub column 13,
Since the unevenness is not formed at the adjacent portion of the earthquake-resistant wall 15 and a smooth state is obtained, the aesthetic appearance at the adjacent portion is improved, and the absence of the unevenness is advantageous in plan planning.

Further, between the earthquake-resistant walls 15, 15 arranged side by side in the directions of arrows C, D, these earthquake-resistant walls 15, 1 are arranged.
The non-bearing openings 16 are formed between the sub-pillars 13 connected to the side portions 15b, 15b of the fifth member 5 so as to be vertically adjacent to each other.
It is formed so as to be sandwiched between 4 and 14. That is, the earthquake-resistant walls 15 and 15 are installed through the non-bearing openings 16, and the non-bearing openings 16 are connected to the above-described multi-layer openings 16.
It is part of 0. A non-bearing wall panel (not shown) extending in the directions of arrows C and D is installed in the non-bearing opening 16 so as to close the opening 16, and the non-bearing wall panel and the earthquake-resistant walls 15, 15, etc. What is configured is a door wall 18 (note that a non-bearing wall panel or the like may not be installed in the non-bearing opening 16 and the opening may be used as a freely traversable opening). On the other hand, the first ramen structural structure 2
A plurality of slabs 12 are supported by the frame structure members 20 and 30 and the beam unit 17 at a predetermined floor height interval H1 between the first frame structure 0 and the second frame structure structure 30. The floor spaces 50 are formed between the slabs 12 vertically arranged adjacent to each other. In this embodiment, the floor space 50
Is assumed to be formed of about 20 pieces (that is, the apartment house 1 is a high-rise house of about 20 stories, and the width-to-height ratio (height / column span in the span direction) of the building is about 4. .).

The structure main body 7 is configured as described above. As shown in FIG. 2, a plurality of common corridor members 40 extending in the directions of arrows A and B and basically formed in a floor plate shape are provided on the structure body 7. Each of these common corridor members 40 is installed on the side of the arrow C side in the form of upper and lower layers (only one is shown in FIG. 2).
Are arranged at positions corresponding to the slabs 12 described above. Therefore, the common corridor 40a in each floor space 50 is formed in the form of an outer corridor via these common corridor members 40. In addition, a plurality of balcony members 41 extending in the directions of arrows A and B and basically formed in a floor plate shape are vertically attached to the side of the structure main body 7 on the arrow D side. The balconies 41 are arranged in layers (only one is shown in FIG. 2), and these balcony members 41 are arranged at positions corresponding to the above-described slabs 12.

On the other hand, each floor space 50 has a plurality of dwelling units 5.
As shown in FIG. 2, as shown in FIG. 2, the dwelling units 51 are arranged in a row along the directions of arrows A and B in such a manner as to be separated from each other by the above-described door boundary walls 18. The common corridor member 40 installed corresponding to 50
The common corridor 40a is formed adjacent to the common corridor 40a and has an entrance (not shown) on the common corridor 40a side. Each dwelling unit 51 has, on the arrow D side thereof, a vulconi 41a formed so as to interpose the vulconi member 41 therebetween. Therefore, the vulconi member 41 has a plurality of vulconi 41a corresponding to the plurality of dwellings 51. Are arranged in a row in the directions of arrows A and B.

Since the apartment house 1 is constructed as described above, it resists seismic force or the like due to the toughness of the rigid-frame structural members 20 and 30 in the girder direction, and has a multi-story seismic resistance in the direction of the clam. The resistance against the strength of the earthquake-resistant wall 15 forming the wall 150 and the resistance against the toughness of the boundary beam 14 using the ultra-mild steel which is a low yield point steel are obtained. That is, since the boundary beam 14 that resists seismic force and the like by toughness and the earthquake-resistant wall 15 that resists seismic force and the like by the resistance are mixed in the direction of the tension, almost the whole As compared with the conventional configuration in which the earthquake-resistant wall is installed on the wall, the shear wall 15 can be made relatively small because the boundary beam 14 is mixed, and the structure such as the column 9 supporting the earthquake-resistant wall 15 is reduced as much as possible. Since it is possible to increase the size and height of the apartment house 1 without increasing the size, it is advantageous in planning and the cost can be kept as low as possible. Further, since the two earthquake-resistant walls 15 and 15 are installed through the non-bearing openings 16 in the span direction, the provision of the non-bearing openings 16 makes it possible to install the earthquake-resistant wall almost entirely in the span direction. Compared to the conventional configuration,
Horizontal stiffness is relatively small. Therefore, even if the width-to-height ratio of the building (height / column span in the span direction) is increased to about 4, the vertical force generated in the substructure 6 due to the overturning moment during the earthquake can be suppressed as small as possible. This is advantageous because it is not necessary to increase the size of the substructure 6 (especially the pile 3 and the like) (in addition, since it is not necessary to extend the low-rise part or the underground span, it is advantageous in planning or construction, and the cost is suppressed).

Further, since the boundary beam 14 uses a tough steel material 61 which is an extremely mild steel having a low yield point, the boundary beam 14 is relatively easily yielded by seismic force. That is, the use of extremely mild steel ensures a high deformation performance so that a large member deformation angle is generated in the boundary beam 14. This boundary beam 14 is advantageous because the horizontal rigidity of the apartment house 1 in the span direction can be further reduced, and the seismic response of the building can be reduced. Furthermore, since the energy absorption capacity of the boundary beam 14 using extreme mild steel is increased, plasticization of the structure is suppressed, and soundness of the building is ensured. Since the non-bearing opening 16 does not need to be provided with an earthquake-resistant wall or the like, it is possible to use this portion as an opening that can pass freely. Thereby, the degree of freedom of the plan is improved. Further, in the direction of the tension, the rigidity of the rigid frame structure is approached due to the mixture of the boundary beam 14 and the earthquake-resistant wall 15. This is convenient because it is possible to mix a ramen structure only.

Next, another embodiment of the structure of an apartment house according to the present invention will be described with reference to FIGS. In the embodiment shown in FIG. 4 and FIG.
0, 30 between these ramen structural structures 20, 30
Columns 9 corresponding to the directions of arrows C and D,
In between, one earthquake-resistant wall 15 extending in the directions of arrows C and D,
Non-bearing opening 16 between each of columns 9 on arrow C side and arrow D side
Are installed in a form one by one. Similar to the above-described embodiment, a plurality of the earthquake-resistant walls 15 are vertically connected via frame beams 11 in the directions of arrows C and D, and these earthquake-resistant walls 15 form a multi-layer earthquake-resistant wall 150. In addition, between the multi-story earthquake-resistant wall 150 and the columns 9, 9
The multi-layer openings 160 extending vertically are formed one by one so as to include the non-bearing openings 16 as a part thereof. Further, the earthquake-resistant wall 15, the earthquake-resistant wall 15 and the non-
The columns 9 and 9 adjacent to each other in the directions of arrows C and D via 6 are connected to each other by boundary beams 14 and 14 formed by adopting extremely mild steel. With this configuration, the same effect as in the above-described embodiment can be obtained. In addition, in this embodiment, two non-bearing openings 16 can be formed between the columns 9, 9, so that the horizontal rigidity can be further reduced in the tension direction, and a boundary beam is provided between the columns 9, 9. 14 can be provided two by two, so that the toughness can be further increased in the tension direction.

Next, still another embodiment of the structure of an apartment house according to the present invention will be described with reference to FIGS. In the embodiment shown in FIGS. 6 and 7, the structure of the frame structure 20, 30 in the tension direction between the columns 9, 9 corresponding to the directions of the arrows C, D, which are the tension directions, ie, one earthquake-resistant structure The wall 15 has one non-bearing opening 16 between each column 9
The structure in which the earthquake-resistant wall 15 and the columns 9 and 9 are connected by the boundary beams 14 and 14 respectively is the same as the above-described embodiment shown in FIGS. 4 and 5. is there. However, in the embodiment shown in FIGS. 6 and 7, a common corridor 40 a extending in the directions of arrows A and B and a plurality of balconies arranged in the directions of arrows A and B are provided between the frame structures 20 and 30. 41a are arranged (that is, the common hallway 40a and the balcony 41a are connected to the ramen structural structure 2).
It is installed on the slab 12 installed between 0 and 30. ). A plurality of balconies arranged in the directions of the arrows A and B through the non-bearing openings 16 on the arrow D side among the two non-bearing openings 16 between the columns 9 and 9 corresponding to the directions of the arrows C and D. A common corridor 4 in which a reference numeral 41a is disposed and extends through the non-bearing opening 16 on the arrow C side in the directions of the arrows A and B
0a is arranged. In addition, a partition plate 41b, which is a non-bearing member, is installed in the non-bearing opening 16 on the side of the balcony 41a so as to close the non-bearing opening 16 (for example, the partition plate 41b is broken in an emergency to allow a person to pass through). Is something you can do.). With this configuration, the same effects as those of the above-described embodiments can be obtained. In addition, the columns 9, 9 of the ramen frame structures 20, 30 corresponding to the direction of the space between them.
Since the common corridor 40a and the balcony 41a are arranged between them, the span in the direction of the space between the columns 9, 9 can be made as wide as possible. Therefore, the width-to-height ratio of the building (height / column span in the span direction) can be made as small as possible, so that the vertical force generated in the building foundation due to the overturning moment during the earthquake can be made as small as possible.

Next, still another embodiment of the structure of an apartment house according to the present invention will be described with reference to FIGS. In the embodiment shown in FIG. 8 and FIG. 9, in the structure of the frame structure 20, 30 in the tension direction between the columns 9, 9 corresponding to the directions of arrows C, D, which are the tension directions, FIG.
And 1 between the columns 9, 9 in the embodiment described above shown in FIG.
One load-bearing wall 15 replaces two load-bearing walls 15, 15 with one non-bearing opening 16 in the center. With this configuration, the same effect as in each of the above-described embodiments can be obtained. In addition, since three non-bearing openings 16 can be formed between the columns 9, 9, the horizontal rigidity can be further reduced in the span direction. Further, since three boundary beams 14 can be provided between the columns 9, 9, the toughness can be further increased in the direction of the gap.

In the structure of the multi-family housing according to the present invention, the ramen structural structures such as the ramen structural structures 20 and 30 which are adjacent in the horizontal direction are separated from each other by the ramen structural structures.
One or more earthquake-resistant walls such as one or more earthquake-resistant walls 15 extending in the direction of the space between the columns 9, 9 and the like corresponding to the predetermined direction of the space.
Since it is sufficient to arrange them in the tension direction through non-bearing openings such as the non-bearing openings 16, if the number of earthquake-resistant walls installed between the above-mentioned columns is one or more, two, three, ... … And so on as many as you want. Of course, the number of non-bearing openings (and the number of connecting beams such as the boundary beams 14) is not limited to one, two, three,... Further, in the above-described embodiment, the connecting beam is the boundary beam 14. However, when the beam unit 17 between the columns 9 and 9 is one member having no seam, the boundary beam 14 and the frame beam 1 are used.
The entire beam unit 17 may be used as a connecting beam without distinguishing from the beam unit 1. That is, in this case, the beam unit 17 is provided between each of the earthquake-resistant walls 15 and the columns 9 adjacent to each other in the span direction through the non-bearing openings 16 and the non-bearing openings 16. The shear walls 15, 15 adjacent to each other in the direction are connected to each other.

In the above-described embodiment, the sub pillar 13 is provided on the side of each of the earthquake-resistant walls 15. However, an embodiment in which the sub pillar 13 is not provided is also possible. The effect can be obtained.

As described above, according to the first aspect of the present invention, the slab such as the slab 12 is formed in a plurality of layers in the vertical direction, and the floor space such as the floor space 50 is provided between the vertically adjacent slabs. Are formed in a multi-family housing, each of which has a plurality of pillars such as a plurality of pillars 9 and a plurality of beams such as a plurality of beams 10 connecting between the pillars, which are arranged in parallel with each other so as to extend in a predetermined girder direction. Ramen surface structure 2
0, a plurality of ramen structural structures such as the second ramen structural structure 30 and the like, and between the ramen structural structures adjacent in the horizontal direction, in a predetermined tension direction of the ramen structural structures. Between the corresponding pillars, one or more earthquake-resistant walls, such as one or more earthquake-resistant walls 15 extending in the direction of the span, are arranged and arranged in the direction of the span through non-bearing openings such as the non-bearing openings 16. Between the earthquake-resistant wall and the column adjacent in the tension direction through the non-force-resistant opening or between the earthquake-resistant walls adjacent to each other in the tension direction through the non-force-resistant opening. ,
Since it is constituted by being connected by connecting beams such as boundary beams 14 formed using a tough steel material such as a tough steel material 61 having an elongation performance of substantially 40% or more, in an apartment house having a structure according to the present invention, With respect to seismic force, etc., in the girder direction, it resists by the toughness of the plurality of framed structural members, and in the tension direction, it resists by the strength of the earthquake-resistant wall. It comes to resist by toughness. In other words, in the span direction, the connecting beams that resist toughness against seismic force and the like and the earthquake-resistant walls that resist due to seismic force and the like are mixed. Compared with the conventional configuration where a wall is installed, the seismic wall can be made relatively small because the connecting beams are mixed, and the structure such as the frame pillar supporting the seismic wall is not enlarged as much as possible. Since it is possible to increase the size and height of the apartment house, it is advantageous in planning and the cost can be kept as low as possible. In addition, since one or more earthquake-resistant walls are installed through the non-bearing openings in the direction of the span, the existing configuration in which the earthquake-resistant walls are installed almost entirely in the direction of the span, because the non-bearing openings exist. The horizontal rigidity is relatively small as compared with. Therefore, even if the width-to-height ratio of the building (height / column span in the span direction) is increased to, for example, about 4, the vertical force generated in the building foundation due to the overturning moment during the earthquake can be suppressed as small as possible. The design of the foundation structure (pile 3) becomes easy. That is, there is no need to increase the size of the substructure, which is convenient. In addition, since it is not necessary to extend the low-rise part or the underground span in the apartment house, it is advantageous in planning or construction, and the cost can be reduced. In addition, since it is not necessary to install an earthquake-resistant wall or the like in the non-bearing opening, it is possible to use this portion as an opening that can pass freely. That is, the degree of freedom of the plan is improved. Furthermore, in the tension direction, the rigidity of the rigid frame structure is approached due to the mixture of the connecting beam and the earthquake-resistant wall. This is convenient because it is possible to mix different types. Furthermore, in the present invention, since the energy absorption capacity of the connecting beam formed using the tough steel material is increased, the plasticization of the structure is suppressed and the soundness of the building is ensured.

According to a second aspect of the present invention, in the structure of an apartment house according to the first aspect, a common corridor such as a common corridor 40a extending in the girder direction is provided in the floor space. Since it was installed using a load-bearing opening, a common corridor will be placed between the horizontally adjacent ramen structural structures and between the columns corresponding to the tension direction of these ramen structural structures. . Therefore, compared with the conventional structure in which the common corridor is arranged between the pillars corresponding to the direction of the span, the common corridor can be arranged inside between these pillars, so that the span in the direction of the span between these pillars is made as wide as possible. it can.
Therefore, in addition to the effects of the first aspect, the width-to-height ratio (height / column span in the direction of the span) of the building can be made as small as possible, so that the vertical force generated in the building foundation due to the overturning moment during an earthquake is made as small as possible. It can be kept small.

According to a third aspect of the present invention, in the structure of an apartment house according to the first aspect, the width of the connecting beam, such as the width W1 in the girder direction, is equal to the width of the earthquake-resistant wall connected to the connecting beam. Since the width is equal to the width W3 or the like in the spar row direction, irregularities are not formed as much as possible at the connection portions between these connection beams and the earthquake-resistant wall, and a smooth state is obtained. Therefore, in addition to the effect of the first invention, the appearance at the connecting portion between the column member and the earthquake-resistant wall is improved, and there is no unevenness, which is advantageous in plan planning.
