[[Mode for Carrying Out the Invention]]

[0010] Hereinafter, a skeleton-infill building (hereinafter also 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 the 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 vertical sectional view of the building 100. The building 100 is, for example, an apartment house, but is not limited thereto. For example, the building 100 may be a commercial store (such as a cafe or a beauty salon) or a public facility (such as a library or a clinic), or may be a mixed-use building including at least two of housing, commercial stores and public facilities. 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 includes a skeleton structure 10 including columns 11 and beams 12, and an infill unit 20 including a floor 21, walls 22, and a ceiling 23. The columns 11 and beams 12 form a grid-shaped 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, for example, a steel structure or a reinforced concrete structure, and functions as a frame that supports 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 uniform spans, but the floor heights do not need to be uniform, and the spans do not need to be uniform. When the floor heights are uniform and the spans are uniform, replacement between infill units 20 is facilitated. The skeleton structure 10 may be a single-story multi-span structural frame, or may be a multi-story single-span structural frame.

[0014] The infill unit 20 shown in Figures 1 and 2 is box-shaped including a floor 21, walls 22, and a ceiling 23, but it may be in a form including only the floor 21. In this case, for example, the infill unit 20 can be used as an outdoor terrace. The infill unit 20 is manufactured, for example, in a factory or the like, and carried into the construction site of the building 100. The infill unit 20 may be manufactured within the construction site. Although not illustrated, the infill unit 20 includes equipment and interior finishes of the building 100.

[0015] As described above, in the building 100, the infill unit 20 including equipment and interior finishes is arranged in a space formed by the skeleton structure 10 that functions as the frame. Since the infill unit 20 and the skeleton structure 10 are physically separated, the infill unit 20 can be easily updated according to needs while leaving the frame unchanged.

[0016] The walls 22 and ceiling 23 of the infill unit 20 are visible in the exterior of the building 100. Since the infill unit 20 can be easily replaced, it also becomes easier to update the exterior wall design and roof design of the building 100.

[0017] When the infill unit 20 is replaced, it can be replaced for a completely different purpose (for example, from a residential unit to a retail unit). The used infill unit 20 may be reused for another purpose without being dismantled. The infill unit 20 preferably has a standardized size, in which case, after the used infill unit 20 is dismantled, the floor 21, walls 22, and ceiling 23 can be recycled and used as materials for a new infill unit 20. By reusing and recycling the infill unit 20, resource waste when replacing the infill unit 20 can be reduced, thereby reducing the environmental impact.

[0018] Figure 3 is a cross-sectional view (vertical section) along the line III-III shown in Figure 2. Figure 4 is a cross-sectional view (horizontal section) along the line IV-IV shown in Figure 3. As shown in Figures 3 and 4, the building 100 is equipped with seismic isolation members 30 that connect the skeleton structure 10 and the infill unit 20. As a result, the infill unit 20 is seismically separated from the skeleton structure 10, and the natural period of the infill unit 20 is lengthened. Therefore, the response acceleration of the infill unit 20 during an earthquake can be reduced, and the risk to the living space can be reduced.

[0019] The effect of extending 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 member 30 allows the infill unit 20 to function as a mass damper, reducing the seismic force generated in the skeleton structure 10. This reduces damage to the skeleton structure 10 during earthquakes and extends its lifespan.

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

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

[0023] The seismic isolation member 30 includes a suspension member 31 whose upper end is connected to a beam 12 of the skeleton structure 10 via a first connecting member 32 and hangs down. The suspension member 31 may be, for example, a wire cable or a chain, but since the suspension member 31 needs to support the weight of the infill unit 20, the use of a wire cable with greater strength is more preferable. 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 lengthening of the period of the infill unit 20 by the suspension member 31 depends on the length of the suspension member 31 and is not affected by the weight of the infill unit 20. Therefore, the lengthening of the period of the infill unit 20 is possible regardless of the weight of the infill unit 20. Consequently, 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 Figure 4, the building 100 is equipped with vibration damping members 40 provided between the skeleton structure 10 and the infill unit 20. The vibration damping members 40 are fluid pressure dampers, such as oil dampers, which dampen the vibrations of the infill unit 20, but viscous dampers or viscoelastic dampers may also be used. The vibration damping members 40 are not shown in Figures 1 to 3. As shown in Figure 4, for example, a total of four vibration damping members 40 are arranged to form a space and connect a pair of opposing beams 12 and the infill unit 20, but in order to effectively dampen vibrations in two horizontal directions, it is sufficient to use a minimum of four vibration damping members and arrange them in two symmetrical sets.

[0026] Figure 5 is a diagram illustrating the construction method of building 100 and corresponds to Figure 3. As shown in Figure 5(a), after constructing the skeleton structure 10, one end of the suspension member 31 is attached to the beam 12 of the skeleton structure 10 via the first connecting member 32, and the suspension member 31 is suspended. Next, as shown in Figure 5(b), the infill unit 20 is lifted using construction heavy machinery 50 (e.g., a crane), 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 the second connecting member 33. After that, the infill unit 20 is removed from the heavy machinery 50.

[0027] In this embodiment, the suspension members 31 are connected to the infill unit 20 while it is suspended by construction heavy machinery 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 machinery 50 is released, the suspension members 31 become tense, and the infill unit 20 automatically moves to the installation position. Therefore, it is not necessary to precisely align the heavy infill unit 20 in the vertical and horizontal directions, thereby improving workability.

[0028] <Second Embodiment> Next, a building 200 according to the second embodiment of the present invention will be described with reference to Figures 6 and 7. In the following, the differences from the first embodiment will be mainly described, 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 as in the first embodiment and their descriptions will be omitted. Furthermore, the schematic perspective view and schematic elevation section of building 200 are substantially the same as the schematic perspective view and schematic elevation section of building 100 shown in Figures 1 and 2, respectively, and therefore will be omitted from the illustration.

[0029] Figure 6 is a cross-sectional view (elevation view) of the building 200, shown in correspondence with Figure 3. As shown in Figure 6, the seismic isolation members 230 of the building 200 include seismic isolation bearings 234 placed on the beams 12 of the skeleton structure 10. The infill unit 20 is placed on the seismic isolation bearings 234. The seismic isolation bearings 234 are, for example, laminated rubber, linear sliders, or sliding bearings.

[0030] In this embodiment, as in the first embodiment, the infill unit 20 is seismically separated from the skeleton structure 10, and the natural period of the infill unit 20 is lengthened. Therefore, the response acceleration of the infill unit 20 during an earthquake can be reduced. In addition, 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 unit 20 can be replaced more easily, and the on-site construction work of the building 200 can be reduced, significantly shortening the construction period.

[0031] Figure 7 is a diagram illustrating the construction method of the building 200 and is shown in correspondence with Figure 6. As shown in Figure 7(a), after constructing the skeleton structure 10, seismic isolation bearings 234 are placed on the beams 12 of the skeleton structure 10. Next, as shown in Figure 7(b), the infill unit 20 is lifted using construction heavy machinery 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. After that, the suspension support of the infill unit 20 by the heavy machinery 50 is removed.

[0032] In this embodiment, when the suspension support of the infill unit 20 by the heavy machinery 50 is released, the infill unit 20 automatically moves to the installation position due to the restoring force of the seismic isolation bearing 234. Therefore, it is not necessary to precisely align the heavy infill unit 20 in the horizontal direction, thereby improving workability.

[0033] <Third Embodiment> Next, a building 300 according to the third embodiment of the present invention will be described with reference to Figures 8 and 9. In the following, the differences from the first embodiment will be mainly described, 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 as in the first embodiment and will not be described. Furthermore, the schematic perspective view and schematic elevation section of building 300 are substantially the same as the schematic perspective view and schematic elevation section of building 100 shown in Figures 1 and 2, respectively, and therefore will not be shown.

[0034] Figure 8 is a cross-sectional view (elevation view) of the building 300, shown in correspondence with Figure 3. As shown in Figure 8, the building 300 is equipped with a winding section 360 for winding up the suspension member 31. The winding section 360 is provided in 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 powered machine such as a motor that can adjust the length of the suspension member 31 by winding it up or unwinding it. By driving the winding unit 360, the length of the suspension member 31 is changed, and the infill unit 20 moves up and down. Therefore, the infill unit 20 can be moved up and down in a shorter time and at a lower cost than when using a crane or the like, 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 used for temporary purposes such as events. Specifically, when there are no events, the infill units 20 are placed on the upper level, leaving the lower level (ground level) open as a passageway, and when there are events, the infill units 20 are installed on the lower level (ground level) and used as a facility. This makes it possible to change the use of each level according to the time of day.

[0037] Furthermore, the building 300 can be provided with an underground layer (not shown), and an infill unit 20 for emergency use can be placed in the underground layer during normal times, and only raised to the surface layer and made available for use in emergencies.

[0038] Figure 9 is a cross-sectional view (horizontal cross-section) along the line IX-IX shown in Figure 8. The winding sections 360 are located in offset positions in plan view in adjacent upper and lower layers. Specifically, if the winding section 360 in the first layer is called "winding section 360a" and the winding section 360 in the second layer above the first layer is called "winding section 360b", then winding sections 360a and 360b are positioned offset from each other in plan view so that they do not overlap. Therefore, the suspension member 31 hanging from winding section 360b is not wound onto winding section 360a.

[0039] <Fourth Embodiment> Next, a building 400 according to the fourth embodiment of the present invention will be described with reference to Figures 10 and 11. In the following, the 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 as in the third embodiment in the figures and their descriptions will be omitted.

[0040] Figure 10 is a schematic vertical cross-sectional view of the building 400. As shown in Figure 10, the building 400 is equipped with horizontal movement mechanisms 471 and 472 for horizontally moving the infill units 20. The horizontal movement mechanisms 471 and 472 enable horizontal movement of the infill units 20 without the use of cranes 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 installed in the underground layer. The infill unit 20 is lowered to the underground layer, placed on the belt conveyor, and 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 rises to the roof and connects to the gondola, and moves horizontally using the power of the gondola.

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

[0044] Alternatively, the infill unit 20 may be moved horizontally using a mechanism different from a belt conveyor or gondola. Figure 11 is a diagram (horizontal cross-sectional view) illustrating a mechanism for moving the infill unit 20 horizontally using wheels 473, and is shown in correspondence with Figure 4. As shown in Figure 11, the wheels 473 are attached to the side of the floor 21 of the infill unit 20. Rails 413 for horizontal movement are provided on the inner surfaces of beams 12 that are adjacent to each other horizontally in the skeleton structure 10. The infill unit 20 moves horizontally as the wheels 473 roll along the rails 413.

[0045] <Modified form of the fourth embodiment> Figure 12 is a partially enlarged vertical cross-sectional view of a modified example of the fourth embodiment of a building 401. As shown in Figure 12, the building 401 is equipped with a traction device 474 (e.g., a traction motor) located on the skeleton structure 10. By applying a horizontal lateral force to the infill unit 20 with the traction device 474, the infill unit 20 can be moved horizontally. The traction device 474 may be provided on all floors of the skeleton structure 10, or it may be provided only on specific floors. On the ground floor, the infill unit 20 may be moved horizontally by a traction vehicle 475.

[0046] <Fifth Embodiment> Next, a building 500 according to the fifth embodiment of the present invention will be described with reference to Figures 13 to 15. In the following, the differences from the first embodiment will be mainly described, 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 as in the first embodiment and will not be described. Furthermore, the schematic perspective view and schematic elevation section of building 500 are substantially the same as the schematic perspective view and schematic elevation section of building 100 shown in Figures 1 and 2, respectively, and therefore will not be shown.

[0047] Figure 13 is a cross-sectional view (elevation view) of building 500, shown in correspondence with Figure 3. Figure 14 is a cross-sectional view (horizontal view) along the line XIV-XIV shown in Figure 13. Figure 15 is an enlarged view of section XIV shown in Figure 13.

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

[0049] In this embodiment, as shown in Figures 13 to 15, the seismic isolation member 530 includes a suspension member 31 and a seismic isolation bearing 534. Specifically, secondary beams 535a and 535b are provided within the span of the beam 12 of the skeleton structure 10, and seismic isolation bearings 534 are placed on the upper surfaces of the secondary beams 535a and 535b, respectively. A beam member 536 is erected across the seismic isolation bearing 534 placed on the secondary beam 535a and the seismic isolation bearing 534 placed on the secondary beam 535b, and the upper end of the suspension member 31 is attached to the beam member 536 via a 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 by selecting the specifications of the linear slider or sliding bearing). Therefore, the natural period of the infill unit 20 can be made longer.

[0051] <Modification 1 of the 5th embodiment> Figure 16 is a cross-sectional view (vertical section) of building 501 according to modification 1 of the fifth embodiment, and is shown in correspondence with Figure 13. As shown in Figure 16, in building 501, the seismic isolation bearing 534 connects the lower end of the suspension member 31 and 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 building 501 as well, the seismic isolation bearing 534 and the suspension member 31 can be arranged in series, so the natural period of the infill unit 20 can be made longer, similar to building 500.

[0052] <Modification 2 of the 5th embodiment> Figure 17 is an enlarged cross-sectional view of building 502 according to modification 2 of the fifth embodiment, and is shown in correspondence with Figure 15. As shown in Figure 17, in building 502, the seismic isolation bearing 534 is a laminated rubber with 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 building 500 (see Figure 15), in order to support the infill unit 20 so that tensile force is not generated in the seismic isolation bearings 534, it is necessary to provide beam members 536 across the seismic isolation bearings 534 and attach suspension members 31 to the beam members 536. In building 502, since the suspension members 31 pass through the hollow portion of the seismic isolation bearings 534, tensile force can be prevented from being generated in the seismic isolation bearings 534 without using beam members 536. In other words, since the beam members 536 can be omitted, building 502 can be simplified compared to the case where solid seismic isolation bearings 534 are used, and constructability can be improved.

[0054] <Modification 3 of the 5th embodiment> Figure 18 is an enlarged cross-sectional view of building 503 according to modification 3 of the fifth embodiment, and is shown in correspondence with Figure 15. As shown in Figure 18, in building 503, the seismic isolation bearing 534 is formed hollow so that the cross-section increases as it extends vertically downward. Because the shape makes it easy to secure horizontal clearance with the seismic isolation bearing 534 at the position where the suspension member 31 undergoes the greatest horizontal deformation, the inner diameter of the seismic isolation bearing 534 can be minimized.

[0055] Although embodiments of the present invention have been described above, these embodiments only represent a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

[0056] The uses of buildings 100, 200, 300, 400, 401, 500, 501, 502, and 503 include (1) uses where needs change over time, making the current use inconvenient and requiring renewal, (2) uses required for a limited time, and (3) uses that periodically become unnecessary within a certain period. Examples of uses in (1) include residences, office buildings, government offices, and commercial tenants. Residences may require renewal every few years due to changes in family structure or physical and mental changes requiring changes in the layout. The same applies to office buildings and government offices. Commercial tenants may require renewal every few months due to fluctuations in popularity. Examples of uses in (2) include event facilities for sports. Examples of uses in (3) include seasonal event facilities such as swimming pools and qualification exam facilities, as well as facilities that correspond to the cycle of different days of the week, such as weekday offices and weekend entertainment facilities.

[0057] The infill unit 20 may be a container unit, a unit assembled with CLT panel walls and ceiling on a PC floor slab, or a unit with exterior cladding attached to a steel frame. By forming one or all of the floor 21, walls 22, and ceiling 23 of the infill unit 20 from wood material, the environmental impact can be reduced through carbon sequestration, and the infill unit 20 can be made lighter, improving ease of delivery and lifting during construction.

[0058] When adopting a suspension-type seismic isolation system using suspension members 31, the weight of the infill unit 20 can be reduced by using wood for the infill unit 20, which in turn allows for a reduction in the size of the suspension members 31 (such as the cross-sectional diameter of the wire cable or chain).

[0059] When the suspension-type seismic isolation system is used in conjunction with the winding unit 360, horizontal movement mechanisms 471 and 472, wheels 473, and traction device 474, the infill unit 20 can be made lighter by using wood, thereby reducing the power required for the winding unit 360, horizontal movement mechanisms 471 and 472, wheels 473, and traction device 474, and enabling shorter vertical and horizontal movement times and cost savings.
