  In the building of Patent Document 1, since a part of the living space above the floor slab is used as a stockpile, there is a problem that the original living space is reduced accordingly.

Therefore, in order to solve this problem, for example, the above-mentioned piloti space (base isolation space) can be used as it is as a stockpile of disaster countermeasure equipment. In this case, Inconvenience arises.
[A] The seismic isolation space is always open to the outside, the temperature and humidity are unstable, and equipment piping is often installed, making it unsuitable for use as a stockpile. It is not preferable also from the viewpoint of theft prevention.
[B] After an earthquake occurs, the resident needs to go to the stockpile to collect stockpile, but to secure the function of the seismic isolation rubber, As the housing part (ground) is cut off, the upper housing part and the lower housing part may be displaced laterally in the event of an aftershock, etc. From the viewpoint of ensuring safety when going to stockpile items, it is not preferable.

  The present invention has been proposed in view of the above, and an object of the present invention is to provide a seismic isolation structure that can secure a stockpile of disaster countermeasure equipment directly under a floor slab while solving the above problems all at once.

  In order to achieve the above object, the present invention comprises a foundation and an upper casing that exists above the foundation, and the combination of the floor slab and beam on the lowermost floor in the upper casing and the foundation. In the seismic isolation structure in which a plurality of seismic isolation devices that support the upper frame on the foundation so as to be relatively displaceable in the event of an earthquake are spaced apart from each other, An auxiliary slab that defines a storage space capable of storing disaster countermeasure equipment between the lower surface of the floor slab is integrally coupled, and a plurality of the slabs are provided between the lower surface of the auxiliary slab and the upper surface of the foundation. The first feature is that the seismic isolation device of FIG. 1 is faced and the seismic isolation space that allows relative displacement between the upper frame and the foundation when an earthquake occurs is interposed.

Is provided integrally, and the auxiliary slab is integrally coupled to at least a part of the support leg.

  According to the present invention, in addition to the first or second feature, the floor slab can be opened and closed with an opening having an upper end opened on the floor of the lowest floor and a lower end opened on the ceiling surface of the storage space. A third feature is that a connection passage is provided between the doorway and the floor of the storage space to allow a resident to move in and out of the storage space. And

  In addition to the third feature of the present invention, in addition to the third feature, the floor slab selects a predetermined folded state in which an opening / closing lid for opening / closing the doorway blocks the doorway and a predetermined unfolded state for opening the doorway The opening / closing lid constitutes a part of the floor in the folded state and functions as a fall prevention fence by standing from the opening edge of the doorway in the unfolded state. 4 features.

  Further, the present invention is a seismic isolation structure having any one of the first to fourth characteristics, wherein the upper housing has a plurality of living sections and a resident can live for each living section, The storage space is provided with storage means having a plurality of storage spaces dedicated for each of the plurality of living sections, and each storage space has a disaster countermeasure equipment for a resident of the corresponding living section. It is a fifth feature that can be stored.

  According to the first feature of the present invention, in the seismic isolation structure in which a plurality of seismic isolation devices are provided between the foundation of the lowermost floor slab and the beam in the upper frame and the foundation, Since the auxiliary slab that defines the storage space shielded from the outside is integrally coupled with the lower surface of the floor slab, the seismic isolation space is interposed between the lower surface of the floor slab and the upper surface of the foundation, It is possible to store and store disaster countermeasure equipment sufficiently in normal times in the above-mentioned storage space, which is an indoor space that is directly under the floor slab and has little fluctuation in temperature and humidity (thus making it easy to prepare the storage environment). Therefore, even when the lifeline is cut off after the earthquake, residents who stay in buildings that are earthquake-resistant and strong against earthquakes can sustain their daily lives in their own living space while using stockpiled items. It is effective for improving convenience and reducing stress, and also effective for preventing theft of stored goods and preventing early deterioration during normal times. In addition, a part of the space directly below the floor slab of the fence, which is originally a dead space (base-isolation space), can be used as a storage space, so that there is sufficient storage without reducing the living space in the upper housing It is possible not only to maintain the seismic isolation function of the seismic isolation device, but also for the seismic isolation function, because the necessary space for seismic isolation is secured by the special provision of the storage space. Maintenance work such as seismic isolation devices in the space can be performed without hindrance. Furthermore, even if the resident is going to pick up the stockpile after the earthquake, the upper housing part (floor slab) and the lower housing part (auxiliary slab) of the storage space are connected and integrated with each other.

  Further, according to the second feature, the combined body of the floor slab and the beam is integrally provided with a plurality of support legs that extend below the floor slab and whose lower ends are respectively coupled to the upper ends of the plurality of seismic isolation devices. Since the auxiliary slab is integrally coupled to at least a part of the support legs, the above-mentioned support legs, which are concentrated on the load transmitted from the upper frame to the seismic isolation device, are coupled to this. The integrated auxiliary slab can be effectively reinforced. Further, the auxiliary slab functioning as the partition means for defining the storage space is also used as the reinforcing means for the support legs as described above, thereby contributing to simplification of the structure and cost reduction.

  According to the third feature, the floor slab is provided with an openable / closable doorway having an upper end opened on the floor of the lowermost floor and a lower end opened on the ceiling surface of the storage space. Between the floor and the floor, there is a connecting passage that connects the space to allow residents to move in and out of the storage space. Since it is possible to get off directly to the storage space directly below and it is not necessary to pass outside the building, it can contribute to the improvement of safety and convenience.

  According to the fourth feature, the floor slab is provided with an opening / closing lid that opens and closes the doorway so that the door can take a predetermined folded state that closes the doorway and a predetermined unfolded state that opens the doorway. The open / close lid forms a part of the floor on the lowest floor in the folded state, and stands up from the opening edge of the entrance / exit in the unfolded state, and functions as a fall prevention fence. It can be used both as a means and a fall-preventing means when the doorway is opened, and can contribute to simplification of the structure and cost reduction.

  According to the fifth feature, the storage space is provided with storage means having a plurality of dedicated storage spaces for each of the plurality of living sections of the seismic isolation structure. Because it is possible to store disaster countermeasure equipment for residents in the living section, it is possible to store disaster countermeasure equipment for each living section in a plurality of storage spaces of the storage means. The user can take out the stockpile without excess or deficiency, which is convenient.

  According to the sixth feature, the combination of the floor slab and the beam is integrally coupled with a maisonette slab that defines the lower living space of the maisonette between the lower surface of the floor slab. Since a seismic isolation space is interposed between the lower surface and the upper surface of the foundation, it is possible to form both the storage space and the lower housing space of the maisonette while securing the seismic isolation space. More effective utilization of the space directly under is possible.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, in FIG. 1 to FIG. 4, a disaster prevention support type apartment M as a seismic isolation structure has a base B as a lower housing fixed and supported on a sturdy ground (not shown), and an upper side of the base B. The upper frame S is provided on the foundation B and is elastically supported via a plurality of seismic isolation rubbers R arranged at intervals from each other. The seismic isolation rubber R has sufficient rigidity so that the upper housing S can be held stationary on the foundation B during normal times. When an earthquake occurs, each seismic isolation rubber R is elastically deformed in the same manner as a conventionally known seismic isolation structure, thereby allowing the upper housing S to be displaced relative to the base B (mainly lateral displacement), This prevents excessive vibration and shock caused by the earthquake from being applied to the upper housing S, and prevents each part of the upper housing S from being greatly damaged by vibration and impact. Thus, the seismic isolation rubber R constitutes the seismic isolation device of the present invention.

  The seismic isolation rubber R has the same structure as a well-known conventional seismic isolation rubber widely used in seismic isolation structures. For example, metal discs are laminated in multiple layers in hard rubber. In this state, a cylindrical main body portion Ra that is embedded and integrated, and upper and lower metal mounting flanges Rb and Rc that are integrally joined to the upper and lower ends of the main body portion Ra, respectively.

  In this embodiment, the foundation B is vertically and horizontally in a horizontal plane so as to integrally couple a plurality of foundation piles Ba that are erected and fixed on the ground and arranged at intervals from each other, and upper ends of these foundation piles Ba. An extending foundation beam Bb and a foundation slab Bc integrally coupled to the upper end of the foundation pile Ba and the foundation beam Bb are provided.

  Also, the base B is integrally formed with a column Bd that is formed wider than the base beam Bb and functions as a lower spring support for the seismic isolation rubber R at the intersection between the base beams Bb (that is, directly above the base pile Ba). Provided. The lower mounting flange Rc of the seismic isolation rubber R is detachably coupled and fixed to the upper end portion of the support column Bd by an appropriate fixing means (for example, a bolt).

  Further, a surrounding wall Be standing upward is integrally projected on the outer peripheral edge of the foundation slab Bc, and the upper edge of the surrounding wall Be extends to substantially the same height as the ground E, Acts as a clasp. In addition, a gap 10 is set between the opposing surfaces of the upper edge of the surrounding wall Be and the upper casing S so as to cut the gap (that is, to allow relative displacement therebetween).

  Each part of the foundation B is mainly composed of a framed steel frame and / or reinforcing bar and concrete with the frame embedded therein, as in the conventional well-known foundation structure. Keep on display.

  The upper housing S has a plurality of residence sections 11 and 12 on each floor, as in conventional ordinary apartments, and residents reside in the residence sections 11 and 12, respectively. In particular, in the present embodiment, the plurality of living sections 11 on the lowest floor (that is, the first floor) are configured in a maisonette type, that is, a type having an upper living space Cmu and a lower living space Cmd that are connected to each other by an inner stair 30 '. . A handrail 31 'is attached to the inner stairs 30', and a floor slab 1 on the lowermost floor is provided with a normally open doorway O 'corresponding to the inner stairs 30'.

The upper living space Cmu of the living section 11 and the approach space 18 to the living section 11 are included. In FIG. 2, reference numeral 19 denotes a piping space where facility piping (not shown) is centrally arranged.

  By the way, the floor slab 1 on the lowest floor is located at the intersection of a large and sturdy beam 2 that extends vertically and horizontally below the floor slab 1 and whose vertical width is sufficiently longer than the horizontal width, and the vertical and horizontal beams 2. Thus, a plurality of support legs 3 extending downward from the floor slab 1 are integrally coupled.

  Each support leg 3 is formed to be wider than the beam 2, and functions as a beam reinforcing means that reinforces the intersection by being integrated with the intersection of the vertical and horizontal beams 2, and the upper casing S. And a function as an upper spring support for each seismic isolation rubber R. Thus, the upper mounting flange Rb of the seismic isolation rubber R is detachably coupled and fixed to the lower end portion of the support leg 3 by an appropriate fixing means (for example, a bolt).

  A plurality of support columns 4 extending upward corresponding to the support legs 3 and the support columns 4 are integrated with each other at the upper portion of the combined body U in which the floor slab 1 and the beam 2 on the lowermost floor are combined and integrated. And a wall 5 extending in the vertical direction are integrally provided. The columns 4 and the wall body 5 are integrally coupled to a combined body U ′ of a floor slab 1 ′ and a beam 2 ′ on the upper floor (second floor). Furthermore, the frame structure on the upper floor (the third floor or higher) is the same as the above-described frame structure on the second floor.

  The auxiliary slab 7 that defines the storage space C1 shielded from the outside and the lower surface of the floor slab 1 is integrally coupled to the combined body U of the floor slab 1 and the beam 2 on the lowermost floor. The outer peripheral portion of the auxiliary slab 7 is integrally coupled to the lowermost floor slab 1 and the combined body U of the beam 2 (particularly the lower end portion of the beam 2) and the lower end portion of the support leg 3 that surround this from the four sides. . The storage space C1 is a space for storing and storing a plurality of disaster countermeasure equipment from normal times. In the present embodiment, the storage space C1 is disposed immediately below the entrance hall 14, but the arrangement is the floor slab 1. It can be selected as appropriate immediately below.

  In the storage space C, a storage rocker 20 with an open / close door is installed, and the storage rocker 20 has a dedicated storage space 21 for each of a large number of living sections 11, 12 in the upper housing S. The storage means is configured. A plurality of storage spaces 21... Provided in the storage rocker 20 for each of the residential sections 11 and 12 store various disaster countermeasure equipment dedicated for residents in the corresponding residential section.

  As disaster countermeasure equipment to be stored and stored in each storage space 21, various disaster countermeasures such as emergency food and water, emergency power supply, lighting equipment, cold protection equipment, simple toilet, heating appliance, blanket, cassette stove, etc. Goods can be selected. The storage rocker 20 may be provided with a locking means for each storage space 21. Of course, various disaster countermeasure goods can be appropriately stored in the empty space outside the storage rocker 20 in the storage space C.

  Note that the number of storage rockers 20 installed in the storage space C1 may be one or a plurality as in the embodiment. When only one storage locker 20 is provided, a plurality of storage spaces 21 dedicated to the plurality of living sections 11 and 12 are arranged in parallel in the single storage rocker 20. When a plurality of storage rockers 20 are provided, a dedicated rocker may be used for each single residential section 11 or 12, or a dedicated rocker may be used for several residential sections 11 and 12.

  In addition, in the combined body U of the floor slab 1 and the beam 2 on the lowermost floor, there is a masonette slab 8 that defines the lower living space Cmd of the lowermost floor maisonette-type living section 11 with the lower surface of the floor slab 1. Combined together. The lower living space Cmd is arranged in a stacked state directly below the upper living space Cmu, and the lower living space Cmd is shielded from the outside. The outer peripheral portion of the maisonette slab 8 is integrally connected to the lowermost floor slab 1 and the combined body U of the beam 2 (especially the lower end portion of the beam 2) and the lower end portion of the support leg 3 that surround this from the four sides. .

  Between the upper surface of the foundation B and the lower surfaces of the auxiliary slab 7 and the masonette slab 8, a seismic isolation space C2 that allows relative displacement between the upper housing S and the foundation B when an earthquake occurs is defined. . The seismic isolation space C2 extends horizontally over the entire upper surface of the foundation B, and all the seismic isolation rubber R directly below the upper housing S faces it.

  The seismic isolation space C2 is not only effective for maintaining the seismic isolation function of the seismic isolation rubber R by allowing the relative displacement between the upper casing S and the foundation B, but also the maintenance inspection and replacement of the seismic isolation rubber R. It can be used as a work space for maintenance such as equipment and equipment piping (not shown) installed on the bottom surface of the seismic isolation space C (that is, the top surface of the foundation slab Bc).

  In addition, each part (for example, floor slabs 1, 1 ', beams 2, 2', support legs 3, auxiliary slabs 7, maisonette slabs 8, etc.) of the upper frame S is a framed steel frame as in the known frame structure. The main structure is a skeleton composed of reinforcing bars and / or concrete in which the skeleton is embedded, but the frame structure itself is not the gist of the present invention. .

  Between the upper housing S and the foundation B, stopper means for restricting excessive relative displacement between them and damper means for damping the relative displacement are interposed. Since the structure of these stopper means and damper means is well known in the related art seismic isolation structures using seismic isolation devices such as seismic isolation rubber, further explanation and illustration are omitted.

  By the way, the floor slab 1 on the lowermost floor has an entrance O having an upper end opened on the floor f (the floor of the entrance hall 14 in this embodiment) and a lower end opened on the ceiling surface of the storage space C1. It is provided so that it can be opened and closed by an opening / closing lid H described later.

  Between the entrance / exit O and the floor surface fb of the storage space C1, a stairway 30 is installed and fixed as a connecting passage that connects the space between the entrance / exit O and the floor space fb of the occupant to allow the occupant to move in and out of the storage space C1. On both sides of the stairs 30, handrails 31 for preventing the fall are provided.

  On the floor slab 1 on the lowest floor, the opening / closing lid H has a predetermined folded state H ′ (see FIG. 6A) that closes the entrance / exit O and a predetermined unfolded state H ″ that opens the entrance / exit O (FIG. 6 (see (B)), and this open / close lid H forms a part of the lowermost floor f in the folded state H ′ and in the unfolded state H ″. Stands up from the three open edges of the doorway O and functions as a fall prevention fence.

  In order to achieve the above function, in the present embodiment, the open / close lid H has horizontal positions (see FIG. 7A) and vertical standing positions (see FIGS. 7B to 7D) at the left and right side edges of the entrance / exit O. The first and second cover plates 41 and 42 are pivotally supported so as to be capable of opening and closing. Between the first and second cover plates 41 and 42 and the floor slab 1, there is provided holding means (not shown) capable of selectively holding the cover plates 41 and 42 at the horizontal position and the vertical standing position as needed. .

  In the first and second cover plates 41 and 42, a pair of third cover plates 43 smaller than the cover plates 41 and 42 are folded at positions where they overlap each other on the back surfaces of the first and second cover plates 41 and 42 ( 7 (b)) and a vertical standing position (see FIGS. 7 (c) and 7 (d)) that is folded at a right angle from the folding position and stands on the rear edge of the entrance / exit O (see FIGS. 7 (c) and 7 (d)). It is pivotally supported. Between the first and second cover plates 41 and 42 and the third cover plate 43, a holding means (not shown) that can selectively hold each third cover plate 43 at the folding position and the vertical standing position as needed. Is provided.

  The first to third cover plates 41 to 43 have extension cover plates 44 that can be projected and lowered above the upper end slits of the first to third cover plates 41 to 43 in a state where they are held in the vertical standing position. Each is stored. Between each extended lid 44 and the corresponding first to third lids 41 to 43, there are provided holding means (not shown) that can hold the extended lid 44 at the upper limit position at any time. .

  The first and second cover plates 41 and 42 are fixedly provided with guide bars 45 that function as handrails when they are in the vertical standing position. The guide bar 45 is disposed at a position where the third cover plate 43 does not interfere with the third cover plate 43 even when the third cover plate 43 is in a folding position where the third cover plate 43 overlaps the back surfaces of the first and second cover plates 41 and 42. The The first to third cover plates 41 to 43 and the extension cover plate 44 may be provided with a handle for facilitating the folding and unfolding operations of the cover plates 41 to 44 as required. .

  Next, an operation process for changing the state of the opening / closing lid H from the folded state H ′ (FIG. 6A) that closes the doorway O to the expanded state H ″ that opens the doorway O (FIG. 6B), This will be described with reference to FIG.

  First, the first and second lid plates 41 and 42 of the opening / closing lid H in the folded state H ′ are moved around the horizontal axis from the horizontal position shown in FIG. 7A to the vertical standing position shown in FIG. Rotate upright and hold in its vertical upright position.

  Next, with respect to the first and second lid plates 41 and 42 in the vertical standing position, the third lid plate 43 is rotated about the vertical axis from the folded position shown in FIG. 7B to the vertical standing position shown in FIG. And is held in the vertical standing position.

  After that, the extension lid plate 44 that has been stored in the first to third lid plates 41 to 43 is moved from the upper end slits of the first to third lid plates 41 to 43 as shown in FIG. It slides upward and each extension cover plate 44 is hold | maintained in the raise limit position.

  Thus, the opening / closing lid H can be switched at any time from the folded state H ′ in FIG. 6A to the unfolded state H ″ in FIG. 6B. The switching operation to ′ may be performed in the reverse procedure to the above.

  The opening / closing lid H opens the entrance / exit O in the unfolded state H ″, and stands up from the three opening edges of the entrance / exit O to function as a fall-preventing fence. It is possible to prevent a fall accident from the floor f on the lowermost floor to the storage space C2 side, and to ensure safety.The open / close lid H is in the folded state H ′ and the floor f on the lowermost floor is secured. Because it becomes part, there is no worry of hindrance to walking.

  In addition, the floor slab 1 on the lowermost floor is for maintenance in which the upper end opens on the floor f on the lowermost floor (in this embodiment, the floor of the elevator hall 16) and the lower end opens on the ceiling surface of the seismic isolation space C2. The doorway 50 is provided so that it can be opened and closed at any time with the opening and closing hatch 51. Therefore, by opening this open / close hatch 51, an operator can directly enter and exit the seismic isolation space C2 through the maintenance entrance 50 from the floor f on the lowest floor using a ladder or the like. Maintenance work of the seismic isolation rubber R and equipment in the space C2 can be performed without any trouble.

  A disaster-supporting beverage vending machine 52 is installed on the floor f around the elevator hall 13. The beverage vending machine 52 is used as a beverage vending machine during normal times. However, when a disaster occurs, the beverage vending machine 52 can be set to be used at the time of a disaster to enable free takeout of beverages based on remote operation by a beverage provider or manual operation by an apartment manager. Switching is possible.

  According to the present embodiment described above, in the base-isolated apartment M in which a plurality of base-isolated rubbers R are provided between the foundation U and the combination U of the floor slab 1 and the beam 2 on the lowermost floor in the upper housing S. An auxiliary slab 7 that defines a storage space C1 shielded from the outside with the lower surface of the floor slab 1 is integrally coupled to the combined body U. A seismic isolation space C2 is interposed between the upper surface and the upper surface. As a result, a large number of disaster countermeasure equipment is stored and stored in the storage space C1, which is an indoor space that is directly under the floor slab 1 and has little fluctuation in temperature and humidity (thus making it easy to optimally prepare the storage environment). I can leave.

  Therefore, even when the lifeline is cut off after the earthquake, a condominium resident who stays in the seismically isolated condominium M uses his stored items in the storage space C1 and lives in his / her own living space 11, 12. This is effective for improving the convenience of residents and reducing stress. In other words, the resident can spend some comfort in his / her apartment M without being forced to live in an inconvenient evacuation shelter after the earthquake. Further, since the storage space C1 is shielded from the outside, it is effective for preventing the stock of stored goods during the normal time and preventing early deterioration.

  In addition, a part of the space immediately below the floor slab 1 on the lowermost floor in the upper housing S, which is originally a wide dead space (base isolation space), can be used for the storage space C1. It is possible to secure a sufficiently large storage space C1 in the housing S without causing a decrease in the living space, and the seismic isolation space C2 necessary immediately below the space C1 can also be secured by the special provision of the storage space C1. Therefore, not only is it effective for maintaining the seismic isolation function of the seismic isolation rubber R, but also maintenance work of the seismic isolation rubber R and equipment in the seismic isolation space C2 can be performed without any trouble. Furthermore, even when a resident goes to pick up stock after the earthquake, the upper part (floor slab 1 side) and the lower part (auxiliary slab 7 side) of the storage space C1 are combined and integrated. Since there is no risk of relative displacement when an aftershock occurs, the safety of residents can be ensured.

  Further, in the combined body U of the floor slab 1 and the beam 2 of the present embodiment, a plurality of support legs 3 extending below the floor slab 1 and having lower ends coupled to upper ends of the plurality of seismic isolation rubbers R, respectively. The auxiliary slab 7 is integrally coupled not only to the beam 2 existing around the auxiliary slab 7 but also to the support leg 3. Thereby, the load which acts on the seismic isolation rubber R from the upper housing S is concentrated, and the supporting leg 3 having a particularly large load can be effectively reinforced by using the auxiliary slab 7 coupled and integrated therewith. it can. In addition, the auxiliary slab 7 that functions as a partition wall for storage space definition is also used as a reinforcing means for the support leg 3 as described above, thereby simplifying the structure and reducing costs.

  In addition, the floor slab 1 of the present embodiment is provided with an entrance / exit O that is openable at the upper end of the floor f of the lowest floor and open at the lower end of the ceiling surface of the storage space C1, so that the entrance / exit O and the storage space can be opened and closed. Between the floor surface fb of C1, there is provided a stairway 20 as a connecting passage that connects between them and allows a resident to move in and out of the storage space C1. As a result, when a resident in the apartment M goes to pick up the stock, it is possible to go down directly from the floor f on the lowest floor of the upper housing S to the stock space C1 directly below, and it is necessary to pass outside the building. Therefore, safety and convenience can be improved.

  Further, in the floor slab 1 of the present embodiment, the opening / closing lid H of the entrance / exit O is in a folded state (see FIG. 6 (A)) that closes the entrance / exit O and an unfolded state in which the entrance / exit O is opened (see FIG. 6 (B)). The opening / closing lid H forms a part of the floor f of the lowermost floor in the folded state, and stands up from the opening edge of the entrance / exit O in the unfolded state as a fall prevention fence Function. Thereby, the opening / closing lid H of the entrance / exit O is used as the floor constituting means and the fall prevention means when the entrance / exit O is opened, thereby simplifying the structure and reducing the cost.

  Further, in the storage space C1 of the present embodiment, a storage rocker 20 having a plurality of dedicated storage spaces 21 for each of a plurality of living sections 11 and 12 in the base-isolated apartment M is installed. Can accommodate disaster countermeasure equipment for residents of the corresponding residence sections 11 and 12.

The upper frame S is provided on the foundation B and is elastically supported via a plurality of seismic isolation rubbers R arranged at intervals from each other. The seismic isolation rubber R has sufficient rigidity so that the upper housing S can be held stationary on the foundation B during normal times. When an earthquake occurs, each seismic isolation rubber R is elastically deformed in the same manner as a conventionally known seismic isolation structure, thereby allowing the upper housing S to be displaced relative to the base B (mainly lateral displacement), This prevents excessive vibration and shock caused by the earthquake from being applied to the upper housing S, and prevents each part of the upper housing S from being greatly damaged by vibration and impact. Thus, the seismic isolation rubber R constitutes the seismic isolation device of the present invention.

  The seismic isolation rubber R has the same structure as a well-known conventional seismic isolation rubber widely used in seismic isolation structures. For example, metal discs are laminated in multiple layers in hard rubber. In this state, a cylindrical main body portion Ra that is embedded and integrated, and upper and lower metal mounting flanges Rb and Rc that are integrally joined to the upper and lower ends of the main body portion Ra, respectively.

  In this embodiment, the foundation B is vertically and horizontally in a horizontal plane so as to integrally couple a plurality of foundation piles Ba that are erected and fixed on the ground and arranged at intervals from each other, and upper ends of these foundation piles Ba.

Provided. The lower mounting flange Rc of the seismic isolation rubber R is detachably coupled and fixed to the upper end portion of the support column Bd by an appropriate fixing means (for example, a bolt).

  Further, a surrounding wall Be standing upward is integrally projected on the outer peripheral edge of the foundation slab Bc, and the upper edge of the surrounding wall Be extends to substantially the same height as the ground E, Acts as a clasp. In addition, a gap 10 is set between the opposing surfaces of the upper edge of the surrounding wall Be and the upper casing S so as to cut the gap (that is, to allow relative displacement therebetween).

  Each part of the foundation B is mainly composed of a framed steel frame and / or reinforcing bar and concrete with the frame embedded therein, as in the conventional well-known foundation structure. Keep on display.

  The upper housing S has a plurality of residence sections 11 and 12 on each floor, as in conventional ordinary apartments, and residents reside in the residence sections 11 and 12, respectively.

Thus, a plurality of support legs 3 extending downward from the floor slab 1 are integrally coupled.

  Each support leg 3 is formed to be wider than the beam 2, and functions as a beam reinforcing means that reinforces the intersection by being integrated with the intersection of the vertical and horizontal beams 2, and the upper casing S. And a function as an upper spring support for each seismic isolation rubber R. Thus, the upper mounting flange Rb of the seismic isolation rubber R is detachably coupled and fixed to the lower end portion of the support leg 3 by an appropriate fixing means (for example, a bolt).

  A plurality of support columns 4 extending upward corresponding to the support legs 3 and the support columns 4 are integrated with each other at the upper portion of the combined body U in which the floor slab 1 and the beam 2 on the lowermost floor are combined and integrated. And a wall 5 extending in the vertical direction are integrally provided. The columns 4 and the wall body 5 are integrally coupled to a combined body U ′ of a floor slab 1 ′ and a beam 2 ′ on the upper floor (second floor).

The outer peripheral portion of the maisonette slab 8 is integrally connected to the lowermost floor slab 1 and the combined body U of the beam 2 (especially the lower end portion of the beam 2) and the lower end portion of the support leg 3 that surround this from the four sides. .

  Between the upper surface of the foundation B and the lower surfaces of the auxiliary slab 7 and the masonette slab 8, a seismic isolation space C2 that allows relative displacement between the upper housing S and the foundation B when an earthquake occurs is defined. . The seismic isolation space C2 extends horizontally over the entire upper surface of the foundation B, and all the seismic isolation rubber R directly below the upper housing S faces it.

  The seismic isolation space C2 is not only effective for maintaining the seismic isolation function of the seismic isolation rubber R by allowing the relative displacement between the upper casing S and the foundation B, but also the maintenance inspection and replacement of the seismic isolation rubber R. It can be used as a work space for maintenance such as equipment and equipment piping (not shown) installed on the bottom surface of the seismic isolation space C (that is, the top surface of the foundation slab Bc).

  In addition, each part (for example, floor slabs 1, 1 ', beams 2, 2', support legs 3, auxiliary slabs 7, maisonette slabs 8, etc.) of the upper frame S is a framed steel frame as in the known frame structure. The main structure is a skeleton composed of reinforcing bars and / or concrete in which the skeleton is embedded, but the frame structure itself is not the gist of the present invention. .

  Between the upper housing S and the foundation B, stopper means for restricting excessive relative displacement between them and damper means for damping the relative displacement are interposed. Since the structure of these stopper means and damper means is well known in the related art seismic isolation structures using seismic isolation devices such as seismic isolation rubber, further explanation and illustration are omitted.

  Therefore, even when the lifeline is cut off after the earthquake, a condominium resident who stays in the seismically isolated condominium M uses his stored items in the storage space C1 and lives in his / her own living space 11, 12. This is effective for improving the convenience of residents and reducing stress. In other words, the resident can spend some comfort in his / her apartment M without being forced to live in an inconvenient evacuation shelter after the earthquake. Further, since the storage space C1 is shielded from the outside, it is effective for preventing the stock of stored goods during the normal time and preventing early deterioration.

  In addition, a part of the space immediately below the floor slab 1 on the lowermost floor in the upper housing S, which is originally a wide dead space (base isolation space), can be used for the storage space C1. It is possible to secure a sufficiently large storage space C1 in the housing S without causing a decrease in the living space, and the seismic isolation space C2 necessary immediately below the space C1 can also be secured by the special provision of the storage space C1. Therefore, not only is it effective for maintaining the seismic isolation function of the seismic isolation rubber R, but also maintenance work of the seismic isolation rubber R and equipment in the seismic isolation space C2 can be performed without any trouble. Furthermore, even when a resident goes to pick up stock after the earthquake, the upper part (floor slab 1 side) and the lower part (auxiliary slab 7 side) of the storage space C1 are combined and integrated. Since there is no risk of relative displacement when an aftershock occurs, the safety of residents can be ensured.

  Further, in the combined body U of the floor slab 1 and the beam 2 of the present embodiment, a plurality of support legs 3 extending below the floor slab 1 and having lower ends coupled to upper ends of the plurality of seismic isolation rubbers R, respectively. The auxiliary slab 7 is integrally coupled not only to the beam 2 existing around the auxiliary slab 7 but also to the support leg 3. Thereby, the load which acts on the seismic isolation rubber R from the upper housing S is concentrated, and the supporting leg 3 having a particularly large load can be effectively reinforced by using the auxiliary slab 7 coupled and integrated therewith. it can. In addition, the auxiliary slab 7 that functions as a partition wall for storage space definition is also used as a reinforcing means for the support leg 3 as described above, thereby simplifying the structure and reducing costs.

  In addition, the floor slab 1 of the present embodiment is provided with an entrance / exit O that is openable at the upper end of the floor f of the lowest floor and open at the lower end of the ceiling surface of the storage space C1, so that the entrance / exit O and the storage space can be opened and closed. Between the floor surface fb of C1, there is provided a stairway 20 as a connecting passage that connects between them and allows a resident to move in and out of the storage space C1. As a result, when a resident in the apartment M goes to pick up the stock, it is possible to go down directly from the floor f on the lowest floor of the upper housing S to the stock space C1 directly below, and it is necessary to pass outside the building. Therefore, safety and convenience can be improved.

  Further, in the floor slab 1 of the present embodiment, the opening / closing lid H of the entrance / exit O is in a folded state (see FIG. 6 (A)) that closes the entrance / exit O and an unfolded state in which the entrance / exit O is opened (see FIG. 6 (B)). The opening / closing lid H forms a part of the floor f of the lowermost floor in the folded state, and stands up from the opening edge of the entrance / exit O in the unfolded state as a fall prevention fence Function. Thereby, the opening / closing lid H of the entrance / exit O is used as the floor constituting means and the fall prevention means when the entrance / exit O is opened, thereby simplifying the structure and reducing the cost.

  Further, in the storage space C1 of the present embodiment, a storage rocker 20 having a plurality of dedicated storage spaces 21 for each of a plurality of living sections 11 and 12 in the base-isolated apartment M is installed. Can accommodate disaster countermeasure equipment for residents of the corresponding residence sections 11 and 12. Thereby, since the disaster countermeasure equipment can be separately stored for each of the residence sections 11 and 12 in the plurality of storage spaces 21, each resident can take out the stockpile without excess or deficiency. Is even better.

  In addition, the combination U of the floor slab 1 and the beam 2 on the lowermost floor of the present embodiment is integrally formed with a maisonette slab 8 that defines the lower living space Cmd of the maisonette between the lower surface of the floor slab 1. The seismic isolation space C2 is also interposed between the lower surface of the maisonette slab 8 and the upper surface of the foundation B. As a result, it is possible to form both the storage space C1 and the lower living space C3 of the maisonette while securing the seismic isolation space C2 immediately below the floor slab 1, and further effective utilization of the space immediately below the floor slab 1 is achieved. It is done.

  In addition, the manager of the condominium M explains, for example, how to enter and exit the storage space C1 and the status and usage of the storage items in the space C1, or updates the storage items as appropriate. By holding events for exchanging, etc. at any time, it is possible to raise residents' awareness of disaster prevention from normal times and prepare for disasters.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various design change is possible in the range which does not deviate from the summary.

  For example, in the said embodiment, the floor slab 1 of the 1st floor of the seismic isolation apartment M is illustrated as a floor slab of the lowest floor in the upper frame S of a base isolation structure, and the floor slab 1 and the beam 2 of the 1st floor are illustrated.
