Description

  The present invention relates to a building.

  In a building such as a house, an elevator may be installed for ease of movement to the upper and lower floors. This is especially beneficial for elderly people who have weak legs and have difficulty climbing up and down stairs. However, since the initial cost of installing an elevator is high, there is a consciousness that it will suffice to install it after becoming an elderly person, and there are many cases where an elevator is installed in the case of future renovation.

  As a technique for installing an elevator during renovation in this way, conventionally, there is known a technique of constructing a hoistway adjacent to a building and installing the elevator there (external elevator) (see, for example, Patent Document 1). .

JP 2003-160284 A

  However, in the case of an external elevator, an elevator hoistway is provided so as to project outward from an existing building. For this reason, when such an elevator hoistway cannot be installed due to restrictions on the site or the like, there is a problem that the elevator cannot be installed later. In addition, since a new structure called an elevator hoistway is to be built, there is a problem that the installation cost of the elevator also increases.

  Therefore, an object of the present invention is to provide a building in which an elevator can be retrofitted inside an existing building, and in addition, an elevator can be easily installed and the space can be effectively used in a state before the installation. And

  The present invention employs the following means in order to solve the above problems.

  That is, in the first invention, an elevator retrofit space which is provided on the assumption that the elevator is retrofitted and communicates from the first floor to the upper floor thereof and serves as a hoistway of the elevator, and upper and lower floor boundaries in the elevator retrofit space In the installed state, the elevator retrofit space is divided into a lower floor space portion and an upper floor space portion, while the lower floor space portion and the upper floor space portion are removed by detachment. The floor partition member is provided with a ventilation portion for ventilating the lower floor space portion and the upper floor space portion in the installed state.

  According to the first aspect of the invention, assuming that the elevator is retrofitted, the elevator retrofit space is provided in advance in the building. Therefore, the elevator can be retrofitted inside the existing building. For this reason, when an elevator is retrofitted with renovation or the like, there is no restriction on the site or the like, and an increase in installation cost can be suppressed.

  In addition, the elevator retrofit space is partitioned into a lower floor space portion and an upper floor space portion by an inter-story partitioning member before the elevator is installed. Thereby, the upper floor side space is not made a dead space, but the space can be effectively used. When the floor partition member is removed, a vertical space communicating from the first floor to the upper floor is formed. The vertical space can be used as an elevator hoistway, and the elevator can be easily installed.

  Furthermore, since the ventilation part is provided in the floor partition member, it is possible to ventilate between the lower floor side space part and the upper floor side space part even in a state of being partitioned by the floor partition member. Become. The ventilation can be used to air-condition the building.

  In 2nd invention, it attaches or detaches to the boundary part between the elevator pit provided under the 1st floor side space part in the elevator retrofit space, and the semi-underground space which has the 1st floor side space part and the elevator pit. A first-floor floor partition member that allows the first-floor space and the semi-underground space to communicate with each other by detaching the first-floor-side space and the semi-underground space in the installed state; It has.

  According to the second aspect of the invention, the first floor space portion of the elevator retrofit space is partitioned from the semi-underground space by the first floor partition member before the elevator is installed. For this reason, the space on the first floor of the elevator retrofit space is not made a dead space, but the space can be effectively used.

  In addition, since an elevator pit in which an elevator drive device and the like are installed in advance is provided below the first floor side space, if the first floor partition member is removed, the first floor side space from the elevator pit in the semi-underground space A vertical space extending vertically to the upper floor side space through the portion is formed. Thereby, installation of a drive device etc. becomes easy and elevator installation becomes still easier.

  In 3rd invention, the said floor partition member is a floor structure connected with a building body part, and the said 1st floor partition member is a floor structure mounted in the foundation.

  According to the third aspect of the present invention, the floor partition member is a floor structure connected to the building body part, and the first floor partition member is a floor structure mounted on the foundation. Strength as a structure is secured. As a result, the upper floor side space part and the first floor side space part partitioned by the partition member can be used as a space for a person to enter, and the width of the use form of the space can be widened to improve convenience.

  In a fourth aspect of the invention, at least one of the upper floor space and the first floor space is a storage space.

  According to the fourth aspect of the present invention, the upper floor side space part and the first floor side space part of the elevator retrofit space are used as a storage space that tends to be insufficient in the building, thereby effectively using the elevator retrofit space. Can be planned.

  In a fifth aspect of the present invention, the ventilation portion in the floor partition member is a ventilation slit, and has a ventilation adjustment device that adjusts ventilation through the ventilation slit.

  According to the fifth aspect of the invention, the ventilation adjustment device adjusts the ventilation through the ventilation slit arbitrarily or automatically by the building user, so that the air conditioning of the building using the ventilation slit can be performed more suitably. it can.

  In a sixth aspect of the present invention, a building ventilation system is provided that ventilates a building using the ventilation portion of the floor partition member. The building ventilation system includes a lower floor adjacent space and an upper floor adjacent to the elevator retrofit space. A room temperature sensor for detecting a room temperature of each adjacent space; and a ventilation control means for controlling the ventilation controller based on the room temperature of the lower floor adjacent space and the upper floor adjacent space.

  According to the sixth aspect of the present invention, the ventilation through the ventilation slit of the floor partition member is automatically adjusted by the building ventilation system according to the room temperature of the upper floor adjacent space and the lower floor adjacent space to be air-conditioned. Thus, air conditioning such as reducing the room temperature difference between the upper floor side and the lower floor side can be performed, and a comfortable air environment can be automatically created.

  In the seventh invention, the ventilation control means is configured in the summer mode when the room temperature of the upper floor adjacent space is higher than the room temperature of the lower floor adjacent space and the difference between the room temperatures exceeds a predetermined temperature. In the winter mode, when the room temperature of the lower floor adjacent space is lower than the room temperature of the upper floor adjacent space, and the difference between the room temperatures exceeds a predetermined temperature, The ventilation adjusting device is controlled so as to block the ventilation through the ventilation slit.

  According to the seventh aspect of the present invention, in the summer, when the room temperature of the upper floor adjacent space becomes higher than that of the lower floor due to the rise of hot air toward the upper floor, ventilation through the ventilation slit becomes possible. This ventilation can be used to generate an air flow in the building, for example, to distribute the heat on the second floor side to the first floor side. On the other hand, in the winter season, when the room temperature in the adjacent space on the lower floor becomes lower than that on the upper floor due to a cool air drop toward the lower floor, ventilation through the ventilation slit is blocked. Thereby, it can suppress that the heat of the lower floor side escapes to the upper floor side. As a result, the room temperature difference between the upper floor portion and the lower floor portion can be reduced for each season, and air conditioning in the building can be suitably realized.

  In an eighth aspect of the present invention, the building ventilation system further includes an air volume sensor that is provided in the floor partition member and detects an air volume of the air flow that passes through the ventilation slit, and the ventilation control unit is configured to control the air volume. Based on this, the air flow adjusting device was controlled.

  According to the eighth aspect of the present invention, since the air volume of the air flow passing through the ventilation slit is also a consideration factor in controlling the ventilation adjustment device, the contents of control in performing the ventilation adjustment are further enhanced. Comfortable air conditioning can be realized.

  Hereinafter, an embodiment will be described with reference to the drawings. In this embodiment, the building is embodied as a two-story house.

  FIG. 1 is a longitudinal sectional view schematically showing a house. As shown in FIG. 1, the house 10 has a first floor portion 11 and a second floor portion 12. In the house 10, the first floor portion 11 is provided on the foundation 13, and the roof portion 14 is provided on the second floor portion 12.

  This house 10 is scheduled to be retrofitted with an elevator EV that connects the first floor part 11 and the second floor part 12, and is referred to as an elevator retrofit space 21 (hereinafter referred to as an EV retrofit space 21) for use as a hoistway of the elevator EV. ) Is provided. The EV retrofit space 21 is a blow-off space that allows the first floor portion 11 and the second floor portion 12 to communicate with each other when the elevator EV is installed, and a space that meets the standards of the elevator EV is secured in advance.

  However, as shown in the figure, in the state before the elevator EV is installed, the second floor structure panel 22 is provided in the upper and lower floor boundary portion 15 and is partitioned into the first floor side space portion 21a and the second floor side space portion 21b. Yes. The second floor structure panel 22 is provided in a detachable state. By removing the second floor structure panel 22, the first floor space 21a and the second floor space 21b are communicated with each other. And in the state in which the 2nd floor structure panel 22 is installed, the 2nd floor side space part 21b will be in the state which can be utilized as space space with a floor, for example, it is utilized as storage space.

  In the EV retrofit space 21, a first-floor floor structure panel 23 is provided on the floor side of the first-floor space 21a so as to partition the space below the floor. The underfloor space partitioned by the first-floor floor structure panel 23 is provided with an elevator pit P by the rising portion 13a of the foundation 13 and becomes a semi-underground space. The first-floor floor structure panel 23 is also provided in a removable state, and by removing the first-floor floor structure panel 23, the first-floor space 21a communicates with the elevator pit P under the floor. In the state in which the first floor structure panel 23 is installed, the first floor side space portion 21a is also in a state that can be used as a space space with a floor, and is used as, for example, a storage space.

  Thus, the EV retrofit space 21 exists as a separate space, which is a storage space, that is, the first floor side space portion 21a and the second floor side space portion 21b by the second floor structure panel 22 and the first floor structure panel 23. ing. In the subsequent renovation, the second-floor structure panel 22 and the first-floor structure panel 23 are removed to form an atrium space connected from the elevator pit P to the second-floor space 21b through the first-floor space 21a. The blow-off space becomes a hoistway of the elevator EV, and the elevator EV drive device K is installed in the elevator pit P.

  In this embodiment, the second floor structure panel 22 corresponds to a floor partition member, and the first floor structure panel 23 corresponds to a first floor structure. The first floor side space portion 21a corresponds to the lower floor side space portion, and the second floor side space portion 21b corresponds to the upper floor side space portion.

  In the house 10, the first floor portion 11 is provided with a first floor space 31 adjacent to the first floor side space portion 21a, and the second floor portion 12 is provided with a second floor space 32 adjacent to the second floor side space portion 21b. . The first floor space 31 corresponds to the lower floor adjacent space, and the second floor space 32 corresponds to the upper floor adjacent space.

  A first door 34 is provided at the entrance 33 that leads from the first floor side space 21 a to the first floor space 31, and a second door 36 is provided at the entrance 35 that leads from the second floor side space 21 b to the second floor space 32. . Both door bodies 34 and 36 have undercuts 34a and 36a, and air can be passed between the spaces through the undercuts 34a and 36a. In addition to the undercuts 34a and 46a, a ventilation gallery (not shown) may be provided in the upper portions of the door bodies 34 and 36 and the partition wall portion, and the spaces can be vented through these ventilation openings.

  The first floor space 31 and the second floor space 32 are adjacent to the staircase space 37, and it is possible to go back and forth between the two spaces 31 and 32 through the staircase space 37. As shown in the figure, the first floor space 31 and the second floor space 32 are not only a corridor and a entrance hall that lead to the staircase space 37, but also a room is provided for each, although not shown.

  Next, the configuration of the second floor structure panel 22 and the first floor structure panel 23 will be described in detail. As described above, the floor structure panels 22 and 23 are detachably installed. In addition, as shown in FIG. 1, the second-floor structure panel 22 is characterized in that it has a ventilation performance to ventilate between the first-floor space 21a and the second-floor space 21b.

  FIG. 2 is a cross-sectional view showing the installation configuration of the second floor structure panel 22 and the first floor structure panel 23. As shown in FIG. 2, each of the floor structure panels 22 and 23 has a structure different from the normal floor portion 41 provided adjacent thereto. In the case of the normal floor portion 41, a floor base material 43 such as lightweight cellular concrete (ALC) is laid on the beam member 42 and the foundation 13 which are building driving parts, and the floor finishing material 44 is placed on the floor base material 43. It is provided.

  On the other hand, the second-floor floor structure panel 22 and the first-floor floor structure panel 23 are configured as simple floor panels that can be easily removed. Both are made into a single panel so as to be detachable with respect to the beam member 42 and the interposition member 45 on the foundation 13, and are placed on the beam member 42 or the foundation 13, and fixed members 46 such as bolts and screws. 47 is fixed. If the fixing members 46 and 47 are removed, the floor structure panels 22 and 23 can be easily removed.

  In this embodiment, the EV retrofit space 21 is provided adjacent to the outdoors via the outer wall portion of the house 10. For this reason, the outer wall panel 48 attached to the beam member 42 exists next to the first floor structure panel 23 and the second floor structure panel 22. In addition, on the indoor side, after the first-floor floor structure panel 23 and the second-floor floor structure panel 22 are installed, an inner wall material 49 such as a plaster board is stretched, and the first-floor side space portion 21a and the second-floor side space portion 21b are stored. It can be used as a space.

  Next, the structure which each of the second floor structure panel 22 and the second floor structure panel 22 has individually is demonstrated. First, the second floor structure panel 22 will be described. FIG. 3 is a plan view of the second-floor structure panel 22, and FIG. 3 is appropriately referred to in addition to FIG.

  As shown in FIG. 2, the second floor structure panel 22 includes a frame member 51, a slit floor material 52, and a shutter device 53 as a ventilation adjustment device, which are integrated to form a single panel. ing.

  As shown in FIG. 3, the frame member 51 has a quadrangular shape in plan view, and both ends are supported between the beam members 42 that extend in parallel to the plane dimension of the EV retrofit space 21 (standard for elevator installation). It has only dimensions. At the four corners of the frame member 51, there are mounting portions 51a. The fixing member 46 is provided on the mounting portion 51a and fixes the frame member 51 to the beam member 42. As shown in FIG. 2, a lid member 54 is detachably provided on the attachment portion 51 a, and the lid member 54 is first removed to remove the fixing member 46.

  The slit flooring 52 is provided inside the frame member 51, and is attached to the frame member 51 in a state where strength as a floor structure is secured. The slit flooring 52 has a plurality of ventilation slits 55 that penetrate both the upper and lower surfaces of the slit flooring 52. The ventilation slit 55 corresponds to a ventilation part. As shown in FIG. 3, the ventilation slits 55 are formed so as to extend over substantially the entire area between the opposite sides of the frame member 51 and to be parallel to each other.

  As shown in FIG. 2, the shutter device 53 is provided below the slit flooring 52 and includes a plurality of slats 56 and a slat driving unit 57 that drives the slats 56. Each slat 56 extends along the same direction as the direction in which the ventilation slit 55 extends, and is arranged side by side in the horizontal direction so as to be parallel to each other. Each slat 56 is provided so as to be rotatable about a central axis along the extending direction thereof, and is rotated by driving of a slat driving portion 57.

  As shown in FIG. 2, one end of the rotation range is a first inclined state in which each slat 56 stands up and an inclination angle with respect to a horizontal plane is increased. In this first inclined state, a gap S is formed between the slats 56, and ventilation through the gap S becomes possible. That is, the space between the first floor side space portion 21a and the second floor side space portion 21b can be ventilated through the ventilation slit 55 and the gap S. Thereby, the airflow which distribute | circulates between both the space parts 21a and 21b can be produced.

  On the other hand, FIG. 4 is a cross-sectional view of the second-floor structure panel 22 showing a state in which each slat 56 is disposed at the other end of the rotation range. As shown in FIG. 4, each slat 56 is rotated from the first inclined state and is in a sleeping state, and is in a second inclined state in which the inclination angle with respect to the horizontal plane is reduced. In this second inclined state, the slats 56 partially overlap each other and the gap S is closed. Thereby, it will be in the non-ventilated state which cannot ventilate between the 1st floor side space part 21a and the 2nd floor side space part 21b.

  Incidentally, the second floor side space portion 21b is used as a storage space as described above. The stored items may be directly placed and stored on the second floor structure panel 22, but in terms of preventing the ventilation slit 55 from being blocked, a shelf is installed in the second floor space portion 21b. It is preferable to store the stored items on a shelf.

  Next, the first floor structure panel 23 will be described with reference to FIG. The first floor structure panel 23 includes a frame member 61, a floor material 62, and a heat insulating material 63, which are integrated to form a single panel. The frame member 61 has a quadrangular shape in plan view, and has substantially the same dimensions as the frame member 51 of the second-floor structure panel 22. The frame member 61 also has mounting portions 61a at the four corners, and the fixing member 47 for the first floor structure panel 23 is provided on the mounting portion 61a so that the frame member 61 is used as the interposition member 45 on the base 13. Fix it. A lid member 64 is also detachably provided on the attachment portion 61a, and the lid member 64 is first removed in order to remove the fixing member 47.

  The first-floor floor structure panel 23 is not provided with up-and-down air permeability and requires heat insulation performance for the semi-underground space (elevator pit P), but it is also necessary to ensure ease of panel removal. A function different from that of the floor structure panel 22 is required. For this reason, the floor material 62 is usually the same as the finish of the floor portion 41, and the heat insulating material 63 is not the floor base material 43 but a heat insulating material such as glass wool.

  By the way, if the ventilation function of the second floor structure panel 22 is used, the air permeability between the first floor portion 11 and the second floor portion 12 can be enhanced indoors. Since the house 10 has such a building ventilation system, the building ventilation system will be described next.

  Returning to FIG. 1, the building ventilation system has a controller 71 that controls the building ventilation system. The controller 71 is a well-known microcomputer provided with a CPU or the like, and is installed in a unitized state together with a system operation unit or the like, for example, on the wall surface of an indoor room. A controller that controls a system (for example, an air conditioning system) provided in the house 10 separately from the building ventilation system may have a function as the controller 71 of the building ventilation system.

  A first floor room temperature sensor 72 that detects the room temperature of the first floor portion 11 and a second floor room temperature sensor 73 that detects the room temperature of the second floor portion 12 are connected to the controller 71. The first-floor room temperature sensor 72 and the second-floor room temperature sensor 73 are provided on the wall surfaces of the first-floor space 31 and the second-floor space 32, for example, as illustrated. For this reason, the controller 71 grasps the room temperature of the first floor space 31 detected by the first floor room temperature sensor 72 and the room temperature of the second floor space 32 detected by the second floor room temperature sensor 73, respectively.

  The controller 71 is connected to the slat drive unit 57 provided on the second floor structure panel 22 and outputs a control signal to the slat drive unit 57 to control the rotation of the plurality of slats 56. For this reason, the controller 71 corresponds to a ventilation control means. The controller 71 is also connected to a ceiling fan 74 provided in the ceiling portion of the staircase space 37, and controls the driving of the ceiling fan 74.

  Next, the flow of automatic ventilation control in this building ventilation system will be described based on the flowchart of FIG. The automatic ventilation control process is executed by the controller 71 at a predetermined time period. This control process is started when an automatic control ON operation is performed by a resident, and is ended when an OFF operation is performed due to a long-term absence of the resident.

  In FIG. 5, first, in step S101, room temperature information from the room temperature sensors 72 and 73 is read. Thereby, the room temperature of each of the first floor space 31 and the second floor space 32 is grasped. In a succeeding step S102, a mode determination process is executed. Specifically, based on the season information, it is determined which mode is “summer” or “winter”.

  The season information used as the basis for the determination here can be obtained based on the date timer of the controller 71, room temperature information acquired from the room temperature sensors 72 and 73, and the like. In addition, for example, season information may be obtained based on temperature information obtained from a communication network such as the Internet or an outside temperature sensor connected to the controller 71. In the intermediate period between summer and winter, based on temperature information of room temperature and outside temperature, for example, if it is 23 ° C. or higher, it is regarded as “summer”, and if it is lower than 23 ° C., it is regarded as “winter”.

  Processing branches according to the mode determination result, and if “summer mode” determination is made, the process proceeds to step S103, and if “winter season mode” determination is made, the process proceeds to step S106. FIGS. 6A and 6B are explanatory diagrams for explaining the air flow in the house 10. FIG. 6A illustrates the summer season and FIG. 6B illustrates the winter season. Refer to FIG. 6 as appropriate for the contents of control performed for each mode.

  First, the process in the “summer mode” will be described. In step S103, a second-floor room temperature determination process is executed. In this second-floor room temperature determination, the difference in room temperature from the first-floor room temperature grasped from the detection information of the first-floor room-temperature sensor 72 is larger than a predetermined temperature (for example, 3 ° C.) It is determined whether or not. As shown in FIG. 6A, in the summer (including the case where it is determined to be summer), hot air rises from the first floor space 31 to the second floor space 32 through the staircase space 37 as the indoor temperature rises. Thereby, since hot air gathers in the second floor space 32 and the room temperature rises higher than the first floor space 31, it is determined whether or not the room temperature difference has become larger than a predetermined temperature due to the room temperature rise.

  If the room temperature difference is larger than the predetermined temperature by this determination, the determination in step S104 is affirmed and the process proceeds to the next step S105. If the room temperature difference is equal to or lower than the predetermined temperature, the determination in step S104 is denied and the process is continued. The control process ends. In step S105, a control signal is output to the slat drive unit 57 of the shutter device 53 to set the slat 56 in the open state, that is, the first inclined state. Thereby, the first floor side space portion 21a and the second floor side space portion 21b in the EV retrofit space 21 are in a ventilation state through the gap S between the ventilation slit 55 and the slat 56 of the second floor structure panel 22. Thereafter, this control process is terminated.

  As shown in FIG. 6A described above, an upward airflow from the first floor space 31 to the second floor space 32 is generated as the indoor air environment when the summer mode is determined. Through the undercuts 34a and 36a of the first door body 34 and the second door body 36, the first floor space 31 can be ventilated with the first floor space section 21a and the second floor space 32 with the second floor space section 21b. For this reason, when the first-floor space 21a and the second-floor space 21b are in a vented state, they are dragged by the rising air flow from the first-floor space 31 to the second-floor space 32, and the first-floor space 21a from the second-floor space 21b. A downward airflow is formed. Thereby, indoor air is circulated using the up-and-down ventilation in EV retrofit space 21, and the room temperature difference between the 1st floor part 11 and the 2nd floor part 12 can be eliminated.

  Next, the process in the “winter mode” will be described. In step S106, a first-floor room temperature determination process is executed. In this first-floor room temperature determination, the difference between the first-floor room temperature obtained from the detection information of the first-floor room-temperature sensor 73 and the second-floor room temperature obtained from the detection information of the second-floor room-temperature sensor 73 is more than a predetermined temperature (for example, 3 ° C.) Determine whether it is larger. In the winter season (including the case where it is determined to be winter season), warm air rises from the first floor space 31 to the second floor space 32 through the staircase space 37, and cold air descends from the second floor space 32 to the first floor space 31. Thereby, since cold air gathers in the first floor space 31 and the room temperature is lower than that of the second floor space 32, it is determined whether or not the room temperature difference is larger than a predetermined temperature due to the room temperature decrease.

  If it is determined that the room temperature difference is greater than the predetermined temperature, the determination in step S107 is affirmed and the process proceeds to the next step S108. If the room temperature difference is equal to or less than the predetermined temperature, the determination in step S107 is denied and the process is continued. The control process ends. In step S108, a control signal is output to the slat drive unit 57 of the shutter device 53 to place the slat 56 in the closed state, that is, in the second inclined state. As a result, in the EV retrofit space 21, the first floor side space portion 21a and the second floor side space portion 21b are in a non-ventilated state. In the subsequent step S109, a control signal is output to the ceiling fan 74 to rotate it so as to generate a descending airflow, and then this control process is terminated.

  Then, as shown in FIG. 6B, a descending airflow from the first floor space 31 to the second floor space 32 through the staircase space 37 is formed by the rotation of the ceiling fan 74. Thereby, the warm air gathered in the second floor space 32 is returned to the first floor space 31 side. In addition, since the first floor space portion 21a and the second floor space portion 21b are in a non-ventilated state, the vertical ventilation is blocked in the EV retrofit space 21. Thereby, it can prevent that the warm air of the 1st floor side space part 21a escapes to the 2nd floor side space part 21b, and moves the cold air of the 2nd floor side space part 21b to the 1st floor side space part 21a. By combining these elements, the room temperature difference between the first floor portion 11 and the second floor portion 12 can be eliminated.

  As described above, according to the present embodiment, the following advantageous effects can be obtained.

  (1) Since the EV retrofit space 21 is provided in advance in the house 10 assuming that the elevator EV will be retrofitted, the elevator EV can be retrofitted to an indoor portion of the house 10. For this reason, when an elevator EV is retrofitted with renovation or the like, there is no restriction on the site or the like, and an increase in installation cost can be suppressed.

  (2) In the stage before the elevator installation, the EV retrofit space 21 is partitioned into the first floor side space portion 21a and the second floor side space portion 21b by the second floor structure panel 22. Moreover, the first floor structure panel 23 partitions the first floor space 21a from the semi-underground space where the elevator pits P are provided in advance. Thereby, the first floor side space portion 21a and the second floor side space portion 21b do not become dead spaces but can be used as individual spaces with a floor, and the space can be effectively used. Particularly, since it is used as a storage space that tends to be insufficient in a building, it is preferable in that it can compensate for insufficient storage.

  Both floor structure panels 22 and 23 are detachable, and are configured as simple floor panels that can be easily removed. For this reason, if these floor structure panels 22 and 23 are removed, a vertical space communicating from the elevator pit P through the first floor side space portion 21a to the second floor side space portion 21b is formed. Thereby, the elevator EV can be easily installed later in the vertical space by reforming or the like.

  (3) Since the second floor structure panel 22 has the ventilation slit 55, it is possible to ventilate the space between the first floor space portion 21a and the second floor space portion 21b even in the panel installation state. Using this ventilation, air conditioning in the house 10 can be performed.

  (4) Since the second floor structure panel 22 connected to the beam member 42 and the first floor structure panel 23 placed on the foundation 13 are used as a partition member for partitioning the EV retrofit space 21, the partition portion Then, the strength as a floor structure is secured. Thereby, the first floor side space portion 21a and the second floor side space portion 21b can be used as a space for a person to enter, and the width of the space usage form can be expanded to improve convenience.

  (5) The second floor structure panel 22 is provided with a shutter device 53, and by adjusting the opening degree of the plurality of slats 56, the ventilation through the ventilation slit 55 can be adjusted. Thereby, the resident can adjust the ventilation arbitrarily or automatically, and air conditioning using the ventilation slit 55 can be suitably performed.

  (6) A building ventilation system is provided, and ventilation through the ventilation slit 55 by adjusting the opening of the slat 56 is automatically performed according to the room temperature of the first floor space 31 and the second floor space 32 adjacent to the EV retrofit space 21. Adjusted to Thus, air conditioning such as reducing the room temperature difference between the upper floor side and the lower floor side can be performed, and a comfortable air environment can be automatically created.

  That is, in the summer, when the room temperature of the second-floor space 32 becomes higher than that of the first-floor space 31 due to the rise of hot air to the second-floor side, the slat 56 is opened and ventilation through the ventilation slit 55 is possible. By utilizing this ventilation, the heat on the second floor side is distributed to the first floor side, and air can be circulated in the house 10. On the other hand, when the room temperature of the first floor space 31 becomes lower than that of the second floor space 32 due to the cool air descending to the first floor side in winter, the slats 56 are closed. Thereby, it is possible to suppress the warm air on the first floor side from escaping to the second floor portion 12 through the ventilation slit 55. As a result, the room temperature difference between the first floor side and the second floor side can be reduced for each season, and the air conditioning in the house 10 can be suitably realized.

  Note that the present invention is not limited to the embodiment described above, and may be implemented in the form shown as another example below.

  (A) In the above embodiment, the second-floor floor structure panel 22 and the first-floor floor structure panel 23 are embodied as partition members. However, for one or both of them, a partition panel having no floor structure may be installed instead. Good. In the embodiment, since the first floor side space portion 21a and the second floor side space portion 21b are used as storage spaces, it is assumed that a resident enters inside, and the strength as a floor structure is required. This is because the strength up to is sometimes not required.

  (B) In the above-described embodiment, the second floor structure panel 22 is provided with the shutter device 53 as a ventilation adjustment device and is configured to be switched to the ventilation or non-ventilation state. However, the shutter device 53 is an essential configuration. Instead, this may be omitted. However, in order to function as a building ventilation system using the second-floor structure panel 22, a configuration having the shutter device 53 is preferable. Further, as the ventilation adjustment device, a shutter device having a shutter plate for adjusting the opening degree of the ventilation slit 55 may be employed instead of the shutter device 53 having the slat 56 as in the above embodiment.

  (C) In the above embodiment, the ventilation portion is embodied as the ventilation slit 55, but it is not a long slit like the ventilation slit 55, but on one surface of the floor material provided in the frame member 51. A large number of vent holes may be provided. Moreover, the grating which replaces the slit flooring 52 is provided, and the hole which the grating has is good also as a ventilation part.

  (D) In the said embodiment, although the 1st floor structure panel 23 becomes a structure which does not have ventilation performance, you may also give this 1st floor structure panel 23 ventilation performance. Thereby, as shown in FIG. 7, the air of the elevator pit P can be taken in indoors through the ventilation slit 81, and it can be used for the improvement of indoor air environment. Since the temperature of the air in the elevator pit P is substantially constant throughout the year due to geothermal heat, cold air can be taken indoors in the summer and warm air can be taken indoors in the winter.

  In this case, it can be considered that the air in the elevator pit P is directly and forcibly introduced indoors by a fan device or the like provided in the elevator pit P. In this case, not only the air is introduced into the first floor side space 21a, but also in the summer, the cold air may be introduced to the second floor side through a duct or the like in consideration of the natural fall of the cold air. In addition, as shown in the drawing, the descending airflow from the second floor space 32 to the first floor space 31 may be formed by rotating the ceiling fan 74. Ascended by the descending airflow, an updraft from the first floor side space portion 21a to the second floor side space portion 21b is generated, and the air in the elevator pit P can be taken in by the updraft.

  (E) In the above embodiment, automatic ventilation control processing using a building ventilation system has been described. However, not only automatic control but also an operation device provided in the controller 71 can be used to manually open and close the slat 56. It is good. Thereby, based on a resident's own judgment with respect to indoor air environment, the slat 56 can be opened and closed and ventilation can be adjusted.

  In addition, regarding the ventilation control process, the control content and the air flow described in the embodiment are merely examples. For example, it is conceivable that hot air rises from the first floor side space portion 21a to the second floor side space portion 21b in the summer when ventilation through the ventilation slit 55 is possible. In this case, if an exhaust port such as a ventilation gallery communicating with the outdoors is provided in the second floor side space portion 21b, heat can be exhausted therefrom. The EV retrofit space 21 plays a role as an exhaust tower, and the room temperature difference between the first floor space 31 and the second floor space 32 can be reduced accordingly. In addition, a fan device may be installed in the first floor side space portion 21a so that the cool air existing on the first floor side is raised to the second floor side. Also in the winter season, instead of blocking the ventilation through the ventilation slit 55, a control for enabling ventilation may be performed. If a fan device is installed in the second-floor space 21b and the rising hot air is lowered, the difference in room temperature between the first-floor space 31 and the second-floor space 32 can be reduced accordingly.

  (F) In the above embodiment, the floor structure panels 22 and 23 are provided on the floor and the floor of the first floor portion 11 respectively. However, when the attic space is provided above the EV retrofit space 21, A configuration in which a ceiling partition panel is provided on the ceiling of the second-floor space 21b may be employed. For example, as shown in FIG. 8, if a detachable ceiling partition panel 83 for partitioning from the attic space 82 is provided in the ceiling portion of the second floor side space portion 21 b, when the elevator EV is installed, the attic space 82 Part of it can be used as an elevator installation space.

  Further, by providing the ceiling partition panel 83 with a ventilation function similar to that of the second-floor structure panel 22, the hot air that has risen to the second-floor space portion 21 b is transmitted through the top light 84 provided on the roof portion 14 in the summer. Can exhaust heat. As the heat flow to the second-floor space 21b, the hot air in the second-floor space 32 is taken in through a vent opening such as the undercut 34a. Further, when the second-floor structure panel 22 is in a ventable state, the hot air in the first-floor space 31 taken into the first-floor space portion 21a through the vent opening such as the undercut 36a passes through the vent slit 55 and reaches the second-floor side. It rises to the space 21b. Here too, the EV retrofit space 21 serves as an exhaust tower, and the room temperature difference between the first floor space 31 and the second floor space 32 can be reduced.

  (G) In the above embodiment, the room temperature sensors 72 and 73 are provided on the wall of the space, but the first floor room temperature sensor 72 is provided on the first floor structure panel 23 and the second floor room temperature sensor 73 is provided on the second floor structure panel 22. You may make it install. In this case, if the controller 71 is also installed on one of the floor structure panels 22 and 23, the building ventilation system is removed along with the removal of the floor structure panels 22 and 23 at the time of renovation. This leads to simplification of the renovation work.

  (H) In the above embodiment, the ventilation control is performed based on the detection information of the room temperature sensors 72 and 73. However, an air volume sensor may be provided and the detection information may be used for the control. In this case, the air volume sensor is provided in the vertical ventilation path (for example, the ventilation slit 55) in the second-floor structure panel 22. The control content can be further enhanced by taking the air volume of the ventilation into consideration. In particular, in the summer when the ventilation is performed, it is possible to perform control such that the slat 56 is driven so as to have an inclination angle with which the air volume is ensured as much as possible, thereby realizing further comfort.

  (I) In the above embodiment, the EV retrofit space 21 is provided adjacent to the outdoors via the outer wall portion of the house 10, but the arrangement of the EV retrofit space 21 is arbitrary. For this reason, for example, the EV retrofit space 21 may be disposed in the central portion of the house 10.

  (J) In the above embodiment, the building is embodied as a two-story house 10, but it is not a single-story multi-story house, a detached house but a building such as a warehouse or a store. May be. In a multi-story building, a floor structure panel having the same configuration as that of the second floor structure panel 22 is installed at the boundary between the floors.
