Description

  The present invention relates to a building that can be used for a house, a store, or the like by being constructed on an inclined land.

  The land of our country is mountainous and there are few plains. In addition, there are many areas where there are few flat lands suitable for housing construction as the mountains approach the coastline, and it is not easy to secure land for housing construction in such areas. For this reason, it is considered that the use of residential land on slopes can be an effective measure for securing land for housing construction.

  In addition, in the Great East Japan Earthquake on March 11, 2011, many detached houses located on a flat land below an altitude of 10m following the coastline were severely damaged by the tsunami generated by the earthquake. The use of residential land on slopes helps to promote the construction of houses in places where sufficient altitude is secured to prevent tsunami damage. In particular, in an area where the mountainous area is within a few km from the coastline, there is an advantage that it is possible to form an urban area integrally with the flat land by constructing a house on an inclined land that is close to the flat land.

  The construction of a detached residential building on a slope with a slope of 1/100 or more and 1/20 or less (hereinafter also referred to as a gentle slope in the present specification) is based on a foundation constructed on a flat site by cutting. It has been widely practiced to construct an upper structure having a space inside (hereinafter also referred to as a sloped first construction method). Also, it is widely practiced to construct a plurality of foundations with different projecting dimensions from the ground surface on a gently sloping ground without flat construction, and to construct an upper structure on these foundations (hereinafter also referred to as a second construction method on a sloping land). It is.

  A plurality of foundations constructed on a gentle slope by the second slope construction method are constructed so that the base on the gentle slope underground side has a larger protruding dimension from the ground surface. For this reason, the distance between the floor constructed horizontally on the lowermost floor of the upper structure and the gently inclined ground surface increases toward the gentle slope underground side (see, for example, FIG. 3 of Patent Document 1).

  Moreover, in the construction of a detached house building on a slope with a slope exceeding 1/20 (hereinafter also referred to as a steep slope in this specification), the foundation built on the flat ground part secured above the natural slope. By securing the overhanging part that protrudes from the edge of the natural ground flat side of the natural ground flat part to the beam installed in the ground, and the upright part of this beam is raised up from the foundation constructed in the natural ground below There is known a method of supporting and constructing a substructure (hereinafter also referred to as a third construction method on an inclined land. For example, see FIG. 1, FIG. 4, FIG. 8, etc. of Patent Document 2). The substructure has a beam, a foundation, and a support. In this method, an upper structure is constructed on a beam of a lower structure (hereinafter also referred to as a base beam).

  The sloped first construction method has a problem that it is difficult to secure a site that can be constructed because there are large restrictions due to the topography of the sloped land and environmental conservation. For this reason, in view of facilitating securing the site, utilization of the above-described second slope construction method and third slope construction method is considered.

JP 2001-193206 A JP 2002-275811 A

  By the way, the inclined land is often configured such that a plurality of strata stacked vertically are exposed on the ground surface or a plurality of strata exist near the ground surface even if they are not exposed on the ground surface. The shaking behavior of the inclined surface layer with respect to the seismic energy varies depending on the location due to the structure and direction of the inclined surface layer and the surrounding stratum, the orientation, the internal structure of the natural ground, and the like.

  Therefore, in the second slope construction method and the third slope construction method, there is a possibility that the difference in the shaking behavior between the foundation construction sites in the slope ground will affect the house building during the action of strong seismic waves. . In addition, if the foundation is constructed in a wider area on the sloped land, the difference in the shaking behavior of each foundation construction location in the natural mountain tends to increase the risk of affecting the residential building. It was an obstacle to making it bigger.

  In addition, in the 3rd construction method of slope land, it is necessary to support one or more places of the overhang | projection part of a base beam with a support | pillar for the stable support of the overhang | projection part of a base beam. For this reason, the third construction method for sloped land requires a number of foundations and supports equal to or greater than the number of foundation beams installed to support the overhanging portions of the foundation beams installed in multiple arrays, and these constructions are troublesome. There is also a problem of hanging.

  The present invention has been made in view of such problems, and the floor of an upper structure (building body) is not increased in a building constructed on an inclined land without increasing the risk of being affected by damage due to the action of seismic waves. The object is to enable an increase in area.

  As shown in FIG.1 and FIG.2, the building 100 which concerns on this embodiment is used for a house (henceforth a housing building), The housing building 100 shown in FIG. Has been built. The residential building 100 includes a foundation 110, a base 120, a platform 130, and a building main body 140 (housing main body). The foundation 110, the base 120, the platform 130, and the building body 140 are provided so as to be stacked from the bottom to the top in this order. The residential building 100 also includes a seismic isolation device 150 interposed between the base 120 and the platform 130.

(Basic)
As shown in FIG. 2, the foundation 110 is constructed in the middle of the slope 11 of the slope 10. The foundation 110 is made of reinforced concrete. The lower part of the foundation 110 is embedded and fixed in the inclined land 10. The foundation 110 illustrated in FIGS. 1 and 2 is formed in a cylindrical shape extending with a central axis in the vertical direction. More specifically, the foundation 110 illustrated in FIGS. 1 and 2 is formed in a rectangular tube shape having a quadrangular cross section and extending in the vertical direction.

  In addition, in this embodiment, although the foundation 110 is provided in the middle of the slope 11, the place where the foundation 110 is constructed is not restricted to this. For example, the foundation 110 may be constructed on a flat ground naturally or artificially formed below the slope 11.

A concrete floor 111 is formed inside the upper portion of the foundation 110.
The concrete floor 111 illustrated in FIGS. 1 and 2 is formed on a natural ground in which the inside of the cylindrical foundation 110 is embedded.

(Base)
A foundation 120 is provided on the foundation 110. The base 120 in the illustrated example is made of reinforced concrete.

  The base 120 includes a frame-shaped portion 121 and an extending portion 122 that extends from the frame-shaped portion 121 to one side thereof. The extending part 122 extends from the frame-shaped part 121 in the direction of the central axis surrounded by the frame-shaped part 121. The frame-shaped part 121 illustrated in FIGS. 1 and 2 is formed in a square frame shape.

  The extension part 122 is a plurality of columnar structures. The extension part 122 extends from the four corners of the frame-like part 121 one by one. The base 120 mounts the four extending portions 122 so as to stand on the corners of the four corners of the foundation 110, respectively, and the central axis of the frame-shaped portion 121 on the extending portions 122 extends in the vertical direction. It is provided on the foundation 110 as it exists. Moreover, each extending part 122 is being fixed to the foundation 110, for example using fixing means, such as on-site concrete and a fastener. In addition, the length of the extension part is 3-5 m.

  A plurality of (four in the illustrated example) extending portions 122 of the base 120 are arranged so as to surround a virtual extension of the inner region of the frame-shaped portion 121. An inner space 123 surrounded by the frame-shaped part 121 and the extension part 122 of the base 120 penetrates the base 120 in the vertical direction.

For the construction of the foundation 120, various known methods such as a precast method and a concrete casting on site can be used.
In the precast method, a base 120 having a structure in which a plurality of concrete members are integrated and assembled may be adopted, and the base 120 may be assembled by integrating a plurality of concrete members carried on the foundation 110.

The concrete floor 111 inside the foundation 110 illustrated in FIGS. 1 and 2 has an upper surface at a position slightly shifted downward from the upper end surface of the foundation 110. The upper end surface of the foundation 110 is formed to extend in the horizontal direction. On the inner side of the upper end portion of the foundation 110, a concave space is secured that is recessed from the upper end of the foundation 110 and has the upper surface of the concrete floor 111 as a bottom surface. The concave space is located on a virtual extension of the inner space 123 of the base 120 and communicates with the inner space 123.
The residential building 100 illustrated in FIGS. 1 and 2 has a lower internal space that is configured by an inner space 123 of the base 120 and a concave space at the upper end of the foundation 110.
The lower internal space can be used for multiple purposes according to the design of the residential building 100 and the lifestyle of the resident. For example, it can be used as a space for storing equipment, storage fixtures, automobile supplies, agricultural and horticultural utensils.
The concrete floor 111 may be formed such that the upper surface thereof is flush with the upper end surface of the foundation 110, or may be formed on the foundation 110 in a slab shape that covers the upper end surface. In the case of the concrete floor 111 of these forms, the lower inner space coincides with the inner space 123 of the base 120.

  As shown in FIGS. 1 and 2, the residential building 100 in the illustrated example is a region (space; hereinafter referred to as “space”) between two extending portions 122 adjacent to each other in the circumferential direction of the base 120 (in the direction around the central axis of the inner space 123). , Also referred to as a region between the extension portions). The earth retaining plate 125 plays a role of preventing inflow into the foundation inner space 123 of flowing water flowing down the slope of the slope 10 or groundwater in the slope 10 of the slope 10 due to earth and sand of the slope 10 earth or rain. The earth retaining plate 125 is disposed so as to extend upward from the lower end (upper end surface of the foundation 110) of the region between the extension portions. In addition, the earth retaining plate 125 has its outer peripheral part directly abutted against the extension part 122 and the upper end surface of the foundation 110 on both sides of the region between the extension parts, or sealed between the extension part 122 and the upper end face of the foundation 110. A material is sandwiched between the extension part 122 and the foundation 110 to ensure waterproofness.

  The earth retaining plate 125 does not necessarily need to block the entire region between the extension portions. For example, in the residential building 100 of FIGS. 1 and 2, the upper end of the retaining plate 125 is located at a position shifted downward from the base frame-shaped portion 121, and the upper end of the retaining plate 125 and the base frame-shaped portion 121 A space 126 is secured between them. The height of the upper end of the retaining plate 125 from the lower end of the region between the extending portions is determined by the height of the inclined ground 10 natural ground around the foundation 110 and the base 120 due to earth and sand, precipitation, etc. from the inclined natural ground 10 ground. It is set as appropriate so as to prevent inflow of flowing water flowing down the slope into the base inner space 123.

A space 126 between the upper end of the base plate 125 and the base frame portion 121 functions as an opening that opens to the side surface of the base 120. Hereinafter, the space 126 is also referred to as a base side opening.
The base side opening 126 communicates with the base inner space 123. The base side opening 126 can be used for ventilation, lighting and the like in the lower internal space.
As will be described later, the platform 130 is provided so as to protrude outside the base 120. For this reason, it is possible to prevent rain or snow from entering the base inner space 123 from the base side opening 126.

  In the residential building 100 illustrated in FIGS. 1 and 2, the four extending portions 122 of the base 120 are connected to the inner space 123 through the central axis (also treated as the central axis of the base 120 in this specification). Two are arranged on the lower side (hereinafter referred to as the lower slope) of the slope 10 and two on the higher side (hereinafter referred to as the upper slope). In FIGS. 1 and 2, reference numerals 122 a and 122 b are attached to the two extended portions 122 on the lower side of the slope of the slope 10 via the center axis of the base 120, and the two extended portions 122 on the higher side are attached. Reference numerals 122c and 122d are assigned.

In the residential building 100 illustrated in FIGS. 1 and 2, a retaining plate 125 is provided in each of the four regions between the extension portions. However, the upper ends of the retaining plates 125 (indicated by reference numeral 125d in the figure) provided between the two extending portions 122a and 122b on the lower side of the slope of the base 120 are the two upper sides of the upper side of the slope of the base 120. The height from the upper end surface of the foundation 110 is lower than the upper end of the earth retaining plate 125 (indicated by reference numeral 125c in the drawing) provided between the extending portions 122c and 122d. In addition, it is provided between the extension part 122c on the slope 10 upper side and the extension part 122b on the slope lower side, and between the extension part 122d on the slope 10 slope upper side and the extension part 122a on the slope lower side, respectively. The height of the upper ends of the earth retaining walls 125a and 125b from the upper end surface of the foundation 110 is an intermediate height between the upper end of the earth retaining wall 125c on the slope of the slope 10 and the upper end of the earth retaining wall 125d on the lower side of the slope.
In addition, when the upper end of the slope 10 ground mountain which touches the side of the slope 110 below the slope 110 of the foundation 110 is located below the top face of the foundation 110, the earth retaining wall 125d below the slope of the slope 110 can be omitted.

(platform)
As shown in FIG. 1, the platform 130 is constructed by assembling the rod-shaped beam members 132 that extend straight, and is a framework provided so as to extend on a virtual plane perpendicular to the center axis of the base 120. It is a structure. The platform 130 of the residential building 100 illustrated in FIGS. 1 and 2 protrudes from the base 120 to the side. Here, the “side” that the platform 130 projects from the base 120 refers to a direction outward from the region on the base 120 in a direction perpendicular to the center axis of the base 120.

The platform 130 of the residential building 100 illustrated in FIGS. 1 and 2 extends along the virtual plane by connecting the beam members 132 arranged vertically and horizontally on a virtual plane perpendicular to the center axis of the base 120. It is built in a matrix.
In this specification, the connection part which connected the front-end | tip parts of the beam material 132 is called a beam connection part. The platform 130 of the residential building 100 illustrated in FIGS. 1 and 2 has, for example, as shown in FIG. 3, the ends of four beam members 132 arranged so as to form a cross shape in plan view are connected by beams. It has a beam connecting portion that is connected and integrated using the member 133. Further, in addition to the beam connecting portion illustrated in FIG. 3, the platform 130 connects and integrates the respective tip portions of the three beam members 132 so as to form a T shape in plan view using the beam connecting member 133. It also has a beam connecting portion that integrates and integrates the beam connecting portions and the tip portions of the two beam members 132 so as to form an L shape in plan view using the beam connecting member 133.

  Since the beam connecting member 133 illustrated in FIG. 3 is a combination of an L-shaped plate 133a and a bolt-nut 133b, the beam members 132 can be connected and disconnected. Thereby, the assembly and disassembly of the platform 130 are facilitated, and the relocation of the residential building 100 is facilitated.

  As a result of connecting the plurality of beam members 132 in this way, a plurality of surrounding regions 134 surrounded by the beam members 132 are defined. The platform 130 of the residential building 100 illustrated in FIG. 1 is constructed in a rectangular shape in plan view as a whole, in which nine surrounding areas 134 are defined in a 3 × 3 matrix. The surrounding area 134 in the center of the 3 × 3 matrix functions as an opening 131 that penetrates the center of the platform 130 in the vertical direction.

  The platform is not limited to the above shape. For example, as shown in FIG. 4A, the platform is surrounded by one beam area using three beams 132 outside the platform 130 at the center of each of the four sides of the outer periphery of the platform 130 illustrated in FIG. 1. The shape provided with 134 may be sufficient. Thereby, a larger living space can be utilized by providing a terrace in the building body 140. Further, for example, as shown in FIG. 4B, the two beam members 132 forming the corners of the 3 × 3 matrix frame may be replaced with one beam member 132. . As a result, the strength of the end portion of the platform 130 can be improved, and the mass of the platform 130 can be concentrated in the center of the platform to stabilize the platform 130 against the swinging force acting on the platform.

  As shown in FIGS. 1 and 2, the platform 130 has an opening 131 in the center in plan view communicating with the base inner space 123 below, and an inner peripheral portion surrounding the opening 131 is disposed on the base 120. Provided on the base 120. The planar view size of the opening 131 of the platform 130 is smaller than the base inner space 123 of the base inner space 123. The platform 130 is provided on the base 120 such that the opening 131 is substantially coaxial with the base inner space 123. An inner peripheral portion around the opening 131 of the platform 130 is installed on the frame-shaped portion 121 of the base 120.

  The platform 130 is provided on the base 120 so that the end portions on the opening 131 side of the eight beam members 132a to 132h projecting outward from the opening 131 in the plan view are positioned on the frame-shaped portion 121. It has been. The beam members 132a to 132h (specifically, the end portion on the opening 131 side) are respectively connected to the base 120 with the seismic isolation devices 150a to 150h provided on the base 120 (the frame-shaped portion 121 in the illustrated example). Is sandwiched between. The platform 130 is supported on the base 120 via the seismic isolation device 150. The platform 130 is connected to the base 120 via a seismic isolation device 150. In the residential building 100 shown in FIG. 1, the seismic isolation device 150 (150 a to 150 h) corresponds to the eight beam members 132 a to 132 h that project outward from the opening 131 of the platform 130. It is provided in the place.

  In the residential building 100 shown in FIG. 1, specifically, the opening 131 of the platform 130 is a base through a gap secured between the platform 130 and the base 120 by the seismic isolation device 150 (150a to 150h). It communicates with the inner space 123.

(Building body)
The building body 140 (upper structure) is constructed on the platform 130 in an annular shape along the inner periphery of the opening 131.
The building body 140 is constructed by connecting an inner hole 141 that vertically penetrates the inner peripheral side of the building main body 140 to the opening 131 approximately coaxially with the opening 131 of the platform 130.
As shown in FIG. 2, the inner hole 141 of the building main body 140 is a lower inner space configured by an inner space 123 of the base 120 and a concave space at the upper end of the foundation 110 through the opening 131 of the platform 130. Communicating with

The residential building 100 also has a panel orientation changing mechanism on the building body 140 that supports the photovoltaic panel 142 and changes the orientation of the photovoltaic panel 142 relative to the building body 140.
The panel orientation changing mechanism illustrated in FIGS. 1 and 2 includes a rail 143 provided in a ring shape centering on the central axis of the inner hole 141 on the building main body 140, and the rail 143 extending direction at a plurality of locations of the rail 143. And a gantry 144 that is movably supported in the circumferential direction of the ring-shaped rail 143. The photovoltaic power generation panel 142 is supported by the gantry 144. The gantry 144 supports the photovoltaic power generation panel 142 with a variable tilt angle via a horizontal rotation axis. The panel orientation changing mechanism includes an endless strip housed in a groove formed over the entire circumference of the rail 143 so as to be movable in the extending direction with respect to the rail 143, and the endless strip body in the direction in which the rail 143 extends. And a motor 145 that moves to and move to. The gantry 144 is attached to an endless strip. For this reason, the panel orientation changing mechanism can change the orientation of the photovoltaic power generation panel 142 supported by the gantry 144 by moving the endless strip by the driving force of the motor 145.

  The residential building 100 illustrated in FIGS. 1 and 2 is configured such that the electric power generated by the solar power generation panel 142 is passed through a storage battery (not shown) provided in the lower internal space through the inner hole 141. Can be stored.

Note that a roof covering the inner hole 141 may be separately provided without providing the photovoltaic power generation panel 142, and the inner hole 141 may be open to the sky.
In the configuration in which the inner hole 141 is opened upward, snowfall falls into the lower inner space via the inner hole 141. As a result, particularly in a snowy country, the load caused by snow on the roof of the building body 140 can be reduced.

A residential building 100 shown in FIG. 1 and FIG. 2 is attached to an end of the platform 130 on the sloped land 10 side, and is bridged between a ground 12 (ground) forming the sloped land 10 and the platform 130. Have
The natural ground 12 is provided with a bridge receiving portion 161. In FIG. 1 and FIG. 2, the bridge receiving portion 161 is specifically a slope 10 slope of a flat surface 12 a (for example, a flat ground including a road) secured above the slope 10 slope of the ground 12 of the slope 10. It is a block-shaped concrete body constructed at the end of the side.

  The bridge 160 shown in FIGS. 1 and 2 is formed in a long plate shape whose longitudinal direction is the interval direction between the end portion of the platform 130 on the inclined land 10 side and the upper surface of the bridge receiving portion 161 of the natural ground 12. The bridge 160 extends from the end portion of the platform 130 on the inclined land 10 side toward the bridge receiving portion 161, and the tip portion thereof is provided on the upper surface of the bridge receiving portion 161. Further, the residential building 100 is constructed such that the end of the upper surface of the bridge 160 on the platform 130 side is positioned at substantially the same height as the upper surface of the bridge receiving portion 161 in the vertical direction. In the residential building 100, the height of the platform 130 is set so that the upper surface of the bridge 160 installed between the upper surface of the bridge receiving portion 161 is horizontal or slightly inclined (for example, within 5 degrees with respect to the horizontal). Built.

The distal end portion of the bridge 160 is slidably mounted on the upper surface of the bridge receiving portion 161. The bridge receiving portion 161 allows a free sliding movement of the distal end portion of the bridge 160 placed on the upper surface in any direction on the upper surface. The upper surface of the bridge receiving portion 161 in FIGS. 1 and 2 is formed to extend in the horizontal direction.
Moreover, the base end part opposite to the front-end | tip part of the bridge | bridging 160 of the residential building 100 shown in FIG. 1, FIG. 2 is attached to the inclined land 10 side edge part of the platform 130 via the rotating shaft 163. FIG. The bridge 160 is rotatable with respect to the platform 130 via a rotation axis 163 with a rotation axis that is parallel to a virtual plane orthogonal to the center axis of the base 120 and perpendicular to the interval direction between the platform 130 and the upper surface of the bridge receiving portion 161. It is pivotally supported. For this reason, the tip of the bridge 160 can be raised and lowered on the upper surface of the bridge receiving portion 161.

Therefore, the front end portion of the bridge 160 is movable in the horizontal direction and the vertical direction with respect to the bridge receiving portion 161. For this reason, the bridge 160 has a relative displacement between the residential building 100 and the natural ground 12 when a relative displacement occurs between the residential building 100 and the natural ground 12 of the inclined land 10 due to an external force such as an earthquake or a strong wind. According to the displacement, relative displacement with respect to the bridge receiving portion 161 can be avoided, and destruction can be avoided. In the configuration in which the bridge 160 is fixed to the platform 130 and the bridge receiving portion 161, the bridge 160 is pulled from the bridge 160 to the platform 130 due to the relative displacement between the residential building 100 and the natural ground 12 of the slope 10, and is sheared and bent. If the bridge 160 is movable with respect to the bridge receiving portion 161 as in the present embodiment, the ground of the residential building 100 and the inclined land 10 may be applied. The force acting on the platform 130 from the bridge 160 in accordance with the relative displacement with respect to 12 is small, and there is no concern about the deformation or breakage of the residential building 100 due to this force.
In addition, when the relative displacement between the residential building 100 and the natural ground 12 of the sloped land 10 occurs, the bridge 160 and the platform 130 and the bridge receiving portion are provided as long as the tip portion thereof is located on the upper surface of the bridge receiving portion 161. 161 can be maintained in a state of being erected with respect to 161 (hereinafter also referred to as an erected state).

The bridge 160 that is rotatable around the rotation shaft 163 is rotated around the rotation shaft 163 so that the tip portion thereof is disposed on the rotation shaft 163 or on the building body 140 side from the rotation shaft 163 (hereinafter also referred to as a storage state). ) Is also possible. As a result, for example, when there is a risk of debris flow or avalanche on the slope of the slope above the flat surface 12a where the bridge receiving portion 161 of the natural ground 12 of the slope 10 is provided, the bridge 160 in the erected state is It is possible to avoid damage and destruction of the bridge 160 in the retracted state.
The bridge 160 can freely switch between the installation state and the storage state by rotating around the rotation shaft 163. The bridge 160 that has been changed from the installed state to the retracted state can be returned to the installed state by rotation about the rotation shaft 163.

  In the present embodiment, the bridge 160 is rotatably provided on the platform 130, but is not limited to this form. The residential building has a configuration in which, for example, the base end of the bridge 160 is supported by a guide member provided at the end of the platform 130 on the inclined land 10 side so as to be movable up and down, and the entire bridge 160 is supported by the platform 130 so as to be movable up and down. Can also be adopted.

  As shown in FIGS. 1 and 2, the residential building 100 has a structure in which a building main body 140 is provided on a platform 130 that is provided so as to protrude from the base 120 to the side thereof. A plan view size (more specifically, a region surrounded by the outer periphery of the top end surface of the foundation 110 in a plan view) of the construction range of the main body 140 on the ground (in FIG. 1 and FIG. 2, an inclined ground 10 ground). ) Can be ensured larger (wider). The construction range of the building main body 140 of the residential building 100 on the platform 130 is such that the distance from the opening 131 of the platform 130 in the extending direction of the platform 130 is larger than the inner periphery of the platform 130 supported by the seismic isolation device 150. It extends far away.

  The building main body 140 of the residential building 100 is provided in a limited area on the ground (10 slopes in FIG. 1 and FIG. 2) having a smaller area than the building area of the building main body 140 on the platform 130. Supported by the foundation 110. Thereby, since the residential building 100 can reduce the influence of the location dependence of the shaking behavior caused by the structure of the stratum of the slope 10 and the like, the damage to the building main body 140 due to the difference in the shaking behavior between the foundation 110 construction points can be prevented. Can be prevented. In addition, the residential building 100 having a structure in which the building body 140 is provided on the platform 130 on the foundation 110 increases the building area of the building body 140 without increasing the risk of being affected by damage due to the action of seismic waves. Can be made.

  Since conventional houses are built in close contact with the ground surface, there is a problem that moisture on the ground and the surface of the ground easily enters the building. On the other hand, in the residential building 100, the building main body 140 is located at a position spaced upward from the ground via the base 120 and the platform 130 from the ground (in this embodiment, the inclined ground mountain 12) on which the foundation 110 is constructed. The provided structure can prevent moisture from the ground from entering the building body 140. Further, in the case of the structure having the base side opening 126, the residential building 100 has a structure with excellent air permeability in which the base inner space 123 and the inner hole 141 of the building main body 140 are blown through, so It is possible to more reliably prevent moisture from entering the building body 140.

As shown in FIG. 2, the base side opening 126 provided between the two extending portions 122 c and 122 d on the upper side of the slope of the base 120 supplies electricity, gas, water, and the like to the residential building 100 from the outside. Therefore, the pipe 181 and the electric cable 182 can function as an insertion space 180 for guiding the lower side internal space.
In the residential building 100 illustrated in FIGS. 1 and 2, a space between the base 120 and the platform 130 between the seismic isolation devices 150 installed at a distance from each other is also lower from the outside of the residential building 100. It can be used as the insertion space 180 for passing the pipe 181 and the electric cable 182 drawn into the side internal space.

As shown in FIGS. 1 and 22, the building body 140 includes a flooring 146 provided on the platform 130.
A supporting tool 135 for supporting the pipe 181 and the electric cable 182 drawn from the outside into the residential building 100 to the platform 130 is provided at a portion of the platform 130 located below the building body 140. In FIG. 2, a pipe 181 and an electric cable 182 drawn from the flat surface 12 a of the sloped ground mountain 12 into the lower internal space of the residential building 100 are supported by a support 135 below the platform 130.
The support tool 135 supports the pipe 181 and the electric cable 182 routed through the insertion space 180 so as to be along the lower surface of the platform 130. Thereby, the part along the platform 130 lower side of the piping 181 and the electric cable 182 can be protected from falling rocks or the like on the slope 10 of the inclined land.

It is preferable to provide a plurality of supports 135 on the platform 130 so that the pipe 181 and the electric cable 182 are arranged along the lower side of the platform 130 as widely as possible. As a result, the portions of the pipe 181 and the electric cable 182 that are largely slackened downward from the platform 130 can be reduced. The portions of the pipe 181 and the electric cable 182 that are largely slackened downward from the platform 130 are likely to be damaged due to large fluctuations caused by strong winds, seismic waves, or the like. For this reason, it is effective in terms of preventing damage to the pipe 181 and the electric cable 182 to provide a plurality of support tools 135 and reduce the slackness of the pipe 181 and the electric cable 182.
In FIG. 2, the configuration in which the piping 181 and the electric cable 182 drawn into the lower internal space from the outside of the residential building 100 through the base side opening 126 is illustrated, but the piping 181 and the outside of the electric cable 182 are illustrated. The configuration in which the pipe 181 and the electric cable 182 are passed through the space between the seismic isolation devices 150 is advantageous in that the exposure is reduced and the pipe 181 and the electric cable 182 are protected from falling rocks on the slope of the slope 10.

  In the illustrated example, the pipe 181 and the electric cable 182 that pass through the insertion space 180 are connected to a device 172 installed in the lower internal space. The apparatus 172 includes a branch facility in which a branch portion of a pipe 171 for supplying fluid to the building main body 140 is housed in a casing, and a distribution board. The device 172 may include, for example, a storage battery or a tank for gas or water. For example, the device 172 may include a private power generation mechanism.

  When the device 172 connected to the pipe 181 or the electric cable 182 includes a storage battery or the like, life can be temporarily maintained in the building main body 140 even when supply of electricity or the like is stopped due to an earthquake.

  In the present embodiment, the pipe 181 and the electric cable 182 extend along the platform 130 via the insertion space 180 and are routed. However, the pipe 181 and the electric cable 182 are not limited to this. It may be led to the lower internal space of the residential building 100.

  As shown in FIG. 1 and FIG. 2, the residential building 100 has a pipe 171 for supplying gas, tap water, etc. to the building main body 140 or draining and exhausting the building main body 140 from the building main body 140. A configuration in which the inner holes 141 are intensively pulled out is adopted. In addition, the residential building 100 purifies fluid that is supplied into or discharged from the building body 140 via the pipe 171 into both the inner hole 141 of the building body 140 and the inner space 123 of the base 120. A fluid processing apparatus 170 for performing processing, heating, or cooling is installed. The ends of the pipes 171 drawn from the building main body 140 to the inner hole 141 are connected to the fluid treatment device 170, respectively.

  The pipe 171 is, for example, a water supply pipe, a drain pipe, an air supply pipe, an exhaust pipe, a heat medium fluid pipe, or a refrigerant fluid pipe. A fluid such as water or gas is supplied into the building main body 140 through the pipe 171, or the fluid flows in from the pipe 171.

  In the illustrated example, the pipe 171 is drawn out from the inside of the annular building main body 140 to the inner hole 141 and connected to the fluid processing apparatus 170 installed in the lower inner space. In the illustrated example, the pipe 171 is connected to both the inner hole 141 of the building body 140 and the inner space 123 of the base 120, but either one may be used.

  The fluid processing apparatus 170 is, for example, an air purifier, and performs a purification process of air (fluid) in the building main body 140. In the illustrated example, an indoor air purifier 170 a is provided in the inner hole 141 of the building main body 140.

  The fluid processing device 170 is, for example, a compressor, and is provided to heat or cool the heat medium fluid or refrigerant fluid flowing into the air conditioning device. In the illustrated example, the indoor compressor 170b is provided in the inner hole 141 of the building main body 140, and the compressor 170c for the lower internal space is provided in the lower internal space.

  Usually, since such a fluid processing apparatus is installed in contact with the outer wall of a residential building, the effective use of the outer wall of the building has been partially hindered. In the residential building 100 of the present invention, the fluid treatment device 170 is provided in one or both of the inner hole 141 of the building main body 140 and the inner space 123 of the base 120, so that the entire outer wall of the residential building 100 can be freely used. it can.

  A water heater 170d is provided in the lower internal space. The hot water heater 170d is a device that heats water supplied from the outside and supplies hot water. The water heater 170d may heat water using, for example, electric power supplied from the outside or heat generated by gas combustion. The hot water heater 170d may heat water using, for example, exhaust heat generated by operation of an air conditioner or the like.

  In order to supply electricity, gas, water and the like to the residential building 100 from the outside, a pipe 181 and an electric cable 182 are provided. As described above, the piping 171 in the residential building 100 is provided in the inner hole 141 of the building body 140 or the inner space 123 of the base 120. For this reason, the pipe 181 and the electric cable 182 need to be drawn into the inner hole 141 of the building body 140 or the inner space 123 of the base 120 from the power plant, the gas tank, the water purification plant, and the like via the inclined land 10.

  The residential building 100 has an insertion space 180 through which the pipe 181 and the electric cable 182 pass. The insertion space 180 is secured between the foundation 110 and the platform 130. In the present embodiment, the pipe 181 and the electric cable 182 are routed from the natural ground 12 to the residential building 100 so as to be suspended in a hollow state without turning over the ground. In the illustrated example, the base side opening 126 provided between the two extending portions 122 c and 122 d on the upper side of the slope of the base 120 is used as the insertion space 180.

  The space under the first floor of a conventional detached house building is narrow and the foundation is almost closed. For this reason, it was difficult to increase the number of pipes under the first floor after completion and to perform maintenance management. In the building body 140, the piping 171 can be freely provided using the lower internal space. For this reason, even after completion of construction, it is possible to easily add and maintain piping and the like.

The traffic between the building main body 140 and the lower internal space can be performed by a sliding ladder or a rope ladder (not shown) provided in the building main body 140. When the traffic is not performed, a ladder or the like is stored in the building body 140. Thereby, it is possible to prevent a suspicious person from entering the building main body 140 from the lower inner space through the base side opening 126.
In order to ensure crime prevention, the base side opening 126 may be covered with a net or a barbed net (not shown). As a result, entry from the outside can be made more difficult without substantially hindering the above-described ventilation effect.

  Note that a staircase or an elevator (not shown) may be permanently installed in the base inner space 123 for traffic between the building body 140 and the lower internal space. In this case, for crime prevention, instead of providing the base side opening 126, the cover plate 125 covers all of the extended portion 122, and a door or the like that can be locked to any of the plate 125 It is desirable to provide an entrance / exit.

  Since the building main body 140 is constructed in an annular shape along the inner periphery of the opening 131, the building main body 140 is designed in a corridor shape so that adjacent rooms on the same floor enter and exit from each other and go around the opening 131. It is possible to make it possible.

  In order to assist elderly people in their homes, it is possible to introduce robots for assistance, nursing care, and cleaning, as well as in-house mobile devices that use trolley rails. In other words, it is difficult to introduce them. In the building main body 140 of the present embodiment, since the rooms on the same floor are designed in a corridor shape, it is easy to introduce a robot and a moving device in a house, and it is possible to support the lives of elderly people.
