Description

[Technical Field]

[0001] The present invention relates to skeleton-infill buildings. [Background technology]

[0002] Skeleton-infill buildings are known in which the skeleton structure, which serves as the building's framework, and the infill, which serves as the building's interior and equipment, are constructed separately. Patent Document 1 discloses that a housing complex consisting of multiple dwelling units is constructed as a skeleton-infill building. In this housing complex, free space is secured in the skeleton structure, which is made up of columns and beams, and each dwelling unit can freely install a balcony or living room in the three spaces as needed.

[0003] Furthermore, Patent Document 1 discloses that the infill is unitized in an apartment building. The infill units are pre-assembled according to the needs of the residents and attached to the skeleton structure via hanging members and braces. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-256715 Summary of the Invention [Problem to be solved by the invention]

[0005] In the apartment building disclosed in Patent Document 1, the infill units are attached to the skeleton structure via hanging materials and bracing materials, so there is a risk that the response acceleration of the infill units along with the skeleton structure will increase during an earthquake.

[0006] The present invention aims to seismically separate an infill unit from a skeleton structure and reduce the response acceleration of the infill unit during an earthquake. [Means for solving the problem]

[0007] The skeleton-infill building according to the present invention comprises a skeleton structure including columns and beams, a space partitioned by the columns and beams, an infill unit including a floor and disposed in the partitioned space, and a seismic isolation member connecting the skeleton structure and the infill unit. The seismic isolation member includes a suspension member whose upper end is connected to the skeleton structure and hangs down, and whose lower end is connected to the infill unit. The seismic isolation member further includes a seismic isolation bearing that connects the upper end of the suspension member to the skeleton structure or the lower end of the suspension member to the infill unit. . In addition, the skeleton-infill building of the present invention comprises a skeleton structure including columns and beams, with a space partitioned by the columns and beams, an infill unit arranged in the space and including a floor, a seismic isolation member connecting the skeleton structure and the infill unit, and a vibration damping member provided between the skeleton structure and the infill unit, and the vibration damping member is arranged symmetrically so as to connect a pair of beams and infill units that form the space and face each other in a plan view. [Effects of the Invention]

[0008] According to the present invention, the infill unit can be seismically separated from the skeleton structure, thereby reducing the response acceleration of the infill unit during an earthquake. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a skeleton-infill building (hereinafter simply referred to as "building") according to an embodiment of the present invention will be described with reference to the drawings.

[0011] First Embodiment First, a building 100 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of the building 100. FIG. 2 is a cross-sectional elevation view of the building 100. The building 100 may be, for example, an apartment building, but is not limited to this. For example, the building 100 may be a commercial store (e.g., a cafe or a beauty salon) or a public facility (e.g., a library or a clinic), or may be a multi-use building including at least two of a residence, a commercial store, and a public facility. The building 100 may also be a hotel, a commercial tenant building, an office, a government office, an event facility, or a combination of these.

[0012] As shown in Figures 1 and 2, a building 100 comprises a skeleton structure 10 including columns 11 and beams 12, and infill units 20 including floors 21, walls 22, and ceilings 23. The columns 11 and beams 12 form a grid-like rigid frame structure. Spaces are partitioned by the columns 11 and beams 12, and one infill unit 20 is arranged corresponding to each partitioned space.

[0013] The skeleton structure 10 is made of, for example, steel or reinforced concrete, and functions as a skeleton supporting the overall load of the building 100. The skeleton structure 10 shown in Figures 1 and 2 is a multi-story, multi-span structural frame with uniform floor heights and spans, but the floor heights and spans do not have to be uniform. If the floor heights and spans are uniform, it becomes easy to interchange the infill units 20. The skeleton structure 10 may be a single-story, multi-span structural frame, or a multi-story, single-span structural frame.

[0014] The infill unit 20 shown in FIGS. 1 and 2 is box-shaped and includes a floor 21, walls 22, and a ceiling 23, but may also include only the floor 21. In that case, the infill unit 20 can be used, for example, as an outdoor terrace. The infill unit 20 is manufactured, for example, in a factory and delivered to the construction site of the building 100. The infill unit 20 may also be manufactured on the construction site. Although not shown, the infill unit 20 includes the equipment and interior of the building 100.

[0015] In this way, in the building 100, the infill units 20, including the equipment and interior, are arranged in the space formed by the skeleton structure 10, which functions as the building frame. Because the infill units 20 and the skeleton structure 10 are physically separated, the infill units 20 can be easily updated according to needs, while leaving the building frame as it is.

[0016] The walls 22 and ceilings 23 of the infill units 20 are visible on the exterior of the building 100. Because the infill units 20 can be easily updated, it also becomes easy to update the exterior wall and roof designs of the building 100.

[0017] When updating the infill units 20, they can be updated for a completely different purpose (for example, from a residential unit to a retail unit). Used infill units 20 may be reused for a different purpose without being dismantled. It is preferable that the infill units 20 have standardized sizes. In this case, after dismantling the used infill units 20, the floors 21, walls 22, and ceilings 23 can be recycled and used as materials for new infill units 20. Reusing and recycling the infill units 20 can reduce resource waste when updating the infill units 20, thereby reducing the environmental impact.

[0018] Fig. 3 is a cross-sectional view (elevation cross-sectional view) taken along line III-III in Fig. 2. Fig. 4 is a cross-sectional view (horizontal cross-sectional view) taken along line IV-IV in Fig. 3. As shown in Figs. 3 and 4, the building 100 is provided with seismic isolation members 30 that connect the skeleton structure 10 and the infill units 20. As a result, the infill units 20 are seismically isolated from the skeleton structure 10, and the natural period of the infill units 20 is lengthened. This reduces the response acceleration of the infill units 20 during an earthquake, reducing the risk of danger to the living space.

[0019] The effect of lengthening the period of the infill unit 20 by the seismic isolation member 30 is greater when the building 100 is low-rise (2-3 stories) to mid-rise (4-5 stories). For this reason, this embodiment is more effective when the building 100 is low-rise to mid-rise.

[0020] Furthermore, the seismic isolation members 30 allow the infill units 20 to function as mass dampers, reducing the seismic force acting on the skeleton structure 10. This reduces damage to the skeleton structure 10 during an earthquake, and extends the life of the skeleton structure 10.

[0021] Since the skeleton structure 10 and the infill units 20 are connected via the seismic isolation members 30, the infill units 20 can be separated from the skeleton structure 10 simply by disconnecting the seismic isolation members 30 from the skeleton structure 10 or the infill units 20. Therefore, the infill units 20 can be more easily updated.

[0022] When installing or updating the facilities and interior functions of the building 100, the infill unit 20 can be lifted by a crane or the like and connected to the skeleton structure 10 via the seismic isolation members 30. This reduces the on-site construction work for the building 100 and significantly shortens the construction period.

[0023] The seismic isolation member 30 includes a suspension member 31 whose upper end is connected to and hangs down from the beam 12 of the skeleton structure 10 via a first connecting member 32. The suspension member 31 is, for example, a wire cable or chain, but since the suspension member 31 needs to support the weight of the infill unit 20, it is more preferable to use a wire cable, which has high strength. The lower end of the suspension member 31 is connected to the infill unit 20, more specifically to the floor 21, via a second connecting member 33.

[0024] The extension of the period of the infill unit 20 by the suspension members 31 depends on the length of the suspension members 31 and is not affected by the weight of the infill unit 20. Therefore, the period of the infill unit 20 can be extended regardless of the weight of the infill unit 20. Therefore, the response acceleration of the infill unit 20 during an earthquake can be reduced without limiting the weight of the infill unit 20.

[0025] As shown in FIG. 4, the building 100 includes vibration damping members 40 disposed between the skeleton structure 10 and the infill units 20. The vibration damping members 40 are fluid pressure dampers, such as oil dampers, that damp the vibrations of the infill units 20. However, other types of damping members, such as viscous dampers and viscoelastic dampers, may also be used. The vibration damping members 40 are not shown in FIGS. 1 to 3. As shown in FIG. 4, for example, a total of four vibration damping members 40 are disposed to define a space and connect a pair of opposing beams 12 and the infill units 20. However, to effectively damp vibrations in two horizontal directions, a minimum of four vibration damping members may be used, disposed in two symmetrical pairs.

[0026] FIG. 5 is a diagram illustrating a construction method for a building 100, and corresponds to FIG. 3. As shown in FIG. 5(a), after constructing a skeleton structure 10, one end of a suspension member 31 is attached to a beam 12 of the skeleton structure 10 via a first connecting member 32, and the suspension member 31 is hung down. Next, as shown in FIG. 5(b), the infill unit 20 is lifted using a construction heavy machine 50 (e.g., a crane), and the infill unit 20 is placed in the space of the skeleton structure 10, and the lower end of the suspension member 31 is attached to the floor 21 of the infill unit 20 via a second connecting member 33. Thereafter, the infill unit 20 is removed from the heavy machine 50.

[0027] In this embodiment, the suspension members 31 are connected to the infill unit 20 while the infill unit 20 is suspended by construction heavy equipment 50 (e.g., a crane), i.e., while the suspension members 31 are relaxed. When the suspension support of the infill unit 20 by the heavy equipment 50 is released, the suspension members 31 become taut, and the infill unit 20 automatically moves to the installation position. Therefore, there is no need to precisely align the heavy infill unit 20 in the vertical and horizontal directions, improving workability.

[0028] Second Embodiment Next, a building 200 according to a second embodiment of the present invention will be described with reference to Figures 6 and 7. Differences from the first embodiment will be mainly described below, and components that are the same as or equivalent to those described in the first embodiment will be denoted by the same reference numerals in the figures and will not be described again. Furthermore, a schematic perspective view and a schematic cross-sectional elevation view of the building 200 are substantially the same as the schematic perspective view and schematic cross-sectional elevation view of the building 100 shown in Figures 1 and 2, respectively, and therefore will not be shown.

[0029] Fig. 6 is a cross-sectional view (elevation cross-sectional view) of the building 200, and is shown corresponding to Fig. 3. As shown in Fig. 6, the seismic isolation member 230 of the building 200 includes a seismic isolation bearing 234 placed on the beam 12 of the skeleton structure 10. The infill unit 20 is placed on the seismic isolation bearing 234. The seismic isolation bearing 234 is, for example, a laminated rubber, a linear slider, or a sliding bearing.

[0030] In this embodiment, as in the first embodiment, the infill units 20 are seismically separated from the skeleton structure 10, and the natural period of the infill units 20 is lengthened. Therefore, the response acceleration of the infill units 20 during an earthquake can be reduced. Also, damage to the skeleton structure 10 during an earthquake can be reduced, and the lifespan of the skeleton structure 10 can be extended. Furthermore, the infill units 20 can be updated more easily, and the on-site construction work of the building 200 can be reduced, significantly shortening the construction period.

[0031] FIG. 7 is a diagram illustrating a construction method for a building 200, and corresponds to FIG. 6. As shown in FIG. 7(a), after constructing a skeleton structure 10, seismic isolation bearings 234 are placed on the beams 12 of the skeleton structure 10. Next, as shown in FIG. 7(b), the infill unit 20 is lifted using heavy construction equipment 50 (e.g., a crane), and the infill unit 20 is placed in the space of the skeleton structure 10, and the floor 21 of the infill unit 20 is placed on the seismic isolation bearings 234. Thereafter, the suspension support of the infill unit 20 by the heavy construction equipment 50 is released.

[0032] In this embodiment, when the heavy equipment 50 is released from the suspension support of the infill unit 20, the infill unit 20 automatically moves to the installation position due to the restoring force of the seismic isolation bearing 234. Therefore, there is no need to precisely align the heavy infill unit 20 horizontally, which improves workability.

[0033] Third Embodiment Next, a building 300 according to a third embodiment of the present invention will be described with reference to Figures 8 and 9. Differences from the first embodiment will be mainly described below, and components that are the same as or equivalent to those described in the first embodiment will be denoted by the same reference numerals in the figures and will not be described again. Furthermore, a schematic perspective view and a schematic cross-sectional elevation view of the building 300 are substantially the same as the schematic perspective view and schematic cross-sectional elevation view of the building 100 shown in Figures 1 and 2, respectively, and therefore will not be shown.

[0034] 8 is a cross-sectional view (elevation cross-sectional view) of the building 300, and is shown corresponding to FIG. 3. As shown in FIG. 8, the building 300 includes a winding section 360 that winds up the suspension material 31. The winding section 360 is provided on the skeleton structure 10. The winding section 360 may be provided on the side surface of the beam 12, or on the bottom surface of the beam 12.

[0035] The winding unit 360 is a power machine such as a motor that can wind up and unwind the suspension material 31 to adjust the length of the suspension material 31. By driving the winding unit 360, the length of the suspension material 31 is changed and the infill unit 20 is raised and lowered. Therefore, compared to using a crane or the like, the infill unit 20 can be moved up and down in a shorter time and at lower cost, and the infill unit 20 can be updated and its position changed in short cycles (for example, on a daily or hourly basis).

[0036] This embodiment is more suitable for infill units 20 that are used for a temporary period, such as for events. Specifically, when there are no events, the infill units 20 are placed on the upper floors, leaving the lower floors (ground level) open as passageways, and when there are events, the infill units 20 are placed on the lower floors (ground level) and used as facilities. This allows the use of each floor to be changed depending on the time of day.

[0037] In addition, the building 300 may have an underground floor (not shown), and the infill unit 20 for emergency use may be placed on the underground floor during normal times, and may be raised to the ground floor only in an emergency to make the infill unit 20 available.

[0038] 9 is a cross-sectional view (horizontal cross-sectional view) taken along line IX-IX in FIG. 8. The winding sections 360 are provided in vertically adjacent layers at positions offset from each other in plan view. Specifically, when the winding section 360 in the first layer is referred to as "winding section 360a" and the winding section 360 in the second layer above the first layer is referred to as "winding section 360b," winding sections 360a and 360b are offset from each other so as not to overlap each other in plan view. Therefore, the hanging material 31 hanging down from winding section 360b is not wound up by winding section 360a.

[0039] <Fourth embodiment> Next, a building 400 according to a fourth embodiment of the present invention will be described with reference to Figures 10 and 11. Below, differences from the third embodiment will be mainly described, and components that are the same as or equivalent to those described in the third embodiment will be denoted by the same reference numerals in the figures as in the third embodiment, and descriptions thereof will be omitted.

[0040] Fig. 10 is a schematic elevational cross-sectional view of the building 400. As shown in Fig. 10, the building 400 is equipped with horizontal movement mechanisms 471 and 472 that horizontally move the infill units 20. The horizontal movement mechanisms 471 and 472 enable the horizontal movement of the infill units 20 without using a crane or the like. Therefore, the infill units 20 can be easily replaced horizontally within the skeleton structure 10.

[0041] The horizontal movement mechanism 471 is a belt conveyor provided in the underground layer. The infill unit 20 descends to the underground layer, is placed on the belt conveyor, and is moved horizontally by the power of the belt conveyor.

[0042] The horizontal movement mechanism 472 is a gondola installed on the roof. The infill unit 20 is raised to the roof and connected to the gondola, and is moved horizontally by the power of the gondola.

[0043] The building 400 is provided with both the horizontal movement mechanism 471 and the horizontal movement mechanism 472, but may be provided with only one of the horizontal movement mechanism 471 and the horizontal movement mechanism 472.

[0044] Furthermore, the infill unit 20 may be moved horizontally using a mechanism other than a belt conveyor or gondola. FIG. 11 is a diagram (horizontal cross section) for explaining a mechanism for moving the infill unit 20 horizontally using wheels 473, and is shown corresponding to FIG. 4. As shown in FIG. 11, the wheels 473 are attached to the side of the floor 21 of the infill unit 20. The skeleton structure 10 has rails 413 for horizontal movement provided on the inner surfaces of beams 12 that are adjacent to each other in the horizontal direction. The wheels 473 roll on the rails 413, causing the infill unit 20 to move horizontally.

[0045] <Modification of the Fourth Embodiment> Fig. 12 is a partially enlarged cross-sectional elevation view of a building 401 according to a modified example of the fourth embodiment. As shown in Fig. 12, the building 401 is provided with a traction device 474 (e.g., a traction motor) disposed on the skeleton structure 10. The traction device 474 applies a horizontal lateral force to the infill unit 20, thereby moving the infill unit 20 horizontally. The traction device 474 may be provided on all floors of the skeleton structure 10, or may be provided only on specific floors. On the ground floor, the infill unit 20 may be moved horizontally by a towing vehicle 475.

[0046] Fifth Embodiment Next, a building 500 according to a fifth embodiment of the present invention will be described with reference to Figures 13 to 15. Differences from the first embodiment will be mainly described below, and components that are the same as or equivalent to those described in the first embodiment will be denoted by the same reference numerals in the figures and will not be described again. Furthermore, a schematic perspective view and a schematic cross-sectional elevation view of the building 500 are substantially the same as the schematic perspective view and the schematic cross-sectional elevation view of the building 100 shown in Figures 1 and 2, respectively, and therefore will not be shown.

[0047] Fig. 13 is a cross-sectional view (elevation cross-sectional view) of the building 500, and corresponds to Fig. 3. Fig. 14 is a cross-sectional view (horizontal cross-sectional view) taken along line XIV-XIV shown in Fig. 13. Fig. 15 is an enlarged view of part XIV shown in Fig. 13.

[0048] The seismic isolation mechanism using the suspension members 31 lengthens the natural period of the infill unit 20 by using the pendulum principle. According to the pendulum principle, the natural period of the infill unit 20 depends only on the length of the suspension members 31. Because the length of the suspension members 31 is limited by the floor height of the skeleton structure 10, there is a limit to how far the natural period of the infill unit 20 can be lengthened by simply adjusting the length of the suspension members 31.

[0049] 13 to 15, the seismic isolation member 530 includes a suspension member 31 and a seismic isolation bearing 534. Specifically, sub-girders 535a and 535b are provided within the span of the beam 12 of the skeleton structure 10, and a seismic isolation bearing 534 is placed on the upper surface of each of the sub-girders 535a and 535b. A beam member 536 is erected across the seismic isolation bearing 534 placed on the sub-girder 535a and the seismic isolation bearing 534 placed on the sub-girder 535b, and the upper end of the suspension member 31 is attached to the beam member 536 via a metal fitting 537.

[0050] In the seismic isolation member 530, the natural period of the infill unit 20 can also be changed by adjusting the specifications of the seismic isolation bearing 534 (specifically, by adjusting the rubber material and shape of the laminated rubber, and selecting the specifications of the linear slider and sliding bearing). Therefore, the natural period of the infill unit 20 can be made longer.

[0051] <Modification 1 of the Fifth Embodiment> Fig. 16 is a cross-sectional view (elevation cross-sectional view) of a building 501 according to Modification 1 of the fifth embodiment, and is shown corresponding to Fig. 13. As shown in Fig. 16, in the building 501, a seismic isolation bearing 534 connects the lower end of the suspension member 31 to the infill unit 20. Specifically, a beam member 536 is attached to the lower end of the suspension member 31, the seismic isolation bearing 534 is placed on the upper surface of the beam member 536, and the infill unit 20 is placed on the upper surface of the seismic isolation bearing 534. In the building 501 as well, the seismic isolation bearing 534 and the suspension member 31 can be arranged in series, and therefore, similar to the building 500, the natural period of the infill unit 20 can be made longer.

[0052] <Modification 2 of Fifth Embodiment> Fig. 17 is an enlarged cross-sectional view of a building 502 according to Modification 2 of the fifth embodiment, and is shown corresponding to Fig. 15. As shown in Fig. 17, in the building 502, the seismic isolation bearing 534 is a laminated rubber member having a hollow planar cross-sectional shape. The upper flange 538 of the seismic isolation bearing 534 is a solid steel plate, and the lower flange 539 is a hollow steel plate. The suspension member 31 is attached to the upper flange 538 and hangs down through the hollow portion of the seismic isolation bearing 534.

[0053] In the building 500 (see FIG. 15), in order to support the infill units 20 so as not to generate tension in the seismic isolation bearings 534, it is necessary to provide beam members 536 between the seismic isolation bearings 534 and attach suspension members 31 to the beam members 536. In the building 502, the suspension members 31 pass through the hollow parts of the seismic isolation bearings 534, so it is possible to prevent tension from being generated in the seismic isolation bearings 534 without using the beam members 536. In other words, because it is possible to omit the beam members 536, the building 502 can be simplified compared to when solid seismic isolation bearings 534 are used, and construction can be facilitated.

[0054] <Modification 3 of Fifth Embodiment> Fig. 18 is an enlarged cross-sectional view of a building 503 according to Modification 3 of the fifth embodiment, and is shown corresponding to Fig. 15. As shown in Fig. 18, in the building 503, the seismic isolation bearings 534 are formed hollow so that their cross sections become larger as they extend vertically downward. At the position where the suspension members 31 undergo the greatest horizontal deformation, the shape of the seismic isolation bearings 534 makes it easy to ensure horizontal clearance with the seismic isolation bearings 534, and therefore the inner diameter of the seismic isolation bearings 534 can be minimized.

[0055] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.

[0056] The uses of buildings 100, 200, 300, 400, 401, 500, 501, 502, and 503 can be classified as follows: (1) uses where needs change over time, causing inconvenience and requiring renewal; (2) uses where uses are needed for a limited period of time; and (3) uses where uses become periodically unnecessary within a certain period of time. Examples of uses in category (1) include residential buildings, office buildings, government offices, and commercial tenants. Residential buildings may require renewal every few years due to changes in family structure or floor plans caused by physical and mental changes. The same is true for office buildings and government offices. Commercial tenants may require renewal every few months due to fluctuations in popularity. Examples of uses in category (2) include event facilities for sports. Examples of uses in category (3) include facilities for seasonal events such as swimming pools and qualification exams, or facilities that correspond to different days of the week, such as offices on weekdays and entertainment facilities on weekends.

[0057] The infill unit 20 may be a container unit, a unit in which CLT panel walls and ceilings are assembled to a PC floor slab, or a unit in which exterior materials are attached to a steel frame. By forming any or all of the floor 21, walls 22, and ceiling 23 of the infill unit 20 from wood materials, the environmental impact can be reduced through the carbon fixation effect, and the weight of the infill unit 20 can be reduced, making it easier to transport and lift during construction.

[0058] When adopting a suspended seismic isolation system using suspension material 31, the weight of the infill unit 20 can be reduced by making the infill unit 20 out of wood, and therefore the size of the suspension material 31 (such as the cross-sectional diameter of the wire cable or chain) can be reduced.

[0059] When the winding section 360, horizontal movement mechanisms 471, 472, wheels 473, and towing device 474 are used in addition to the suspended seismic isolation system, the weight of the infill unit 20 can be reduced by making the infill unit 20 out of wood, and the power required for the winding section 360, horizontal movement mechanisms 471, 472, wheels 473, and towing device 474 can be reduced, thereby shortening the time and reducing the cost of vertical and horizontal movement.
