As shown in FIGS. 1B and 4, the storage battery 30 is fastened and fixed to the upper flange 26 </ b> B and the lower flange 26 </ b> C of the beam member 26 with bolts 34. Specifically, a plurality of bolt insertion holes 36 are coaxially formed in the upper flange 26B and the lower flange 26C of the beam member 26. On the other hand, the upper end wall of the storage battery 30 (more precisely, the upper end wall of the storage battery case forming the outline of the storage battery 30) 38 and the lower end wall (not shown) have internal threads on the inner peripheral surface. Bolt insertion holes 40 are formed. The bolt insertion hole 40 and the bolt insertion hole 36 are arranged coaxially. Then, the storage battery 30 is detachably fixed to the space portion 32 of the beam member 26 by screwing the bolts 34 into the bolt insertion holes 40 from above the upper flange 26B and below the lower flange 26C. Yes. As shown in FIG. 1B, the wiring 42 drawn out from the storage battery 30 is routed in the space 32 of the beam member 26 along the longitudinal direction of the beam member 26 and led to an indoor outlet. .

As the refractory material, a foamable refractory paint that foams at a predetermined high temperature to form a heat insulating layer can be used. As an example, SK Tika Coat (trade name) manufactured by SK Kaken Co., Ltd. can be used. When the fireproof coating material reaches about 250 ° C. in the event of a fire, the fireproof coating layer having a thickness of several millimeters foams to about 20 to 30 times to form a heat insulating layer. In addition, Taikalit (trade name) manufactured by Nippon Paint Co., Ltd., Nullifier System S (trade name) manufactured by Nalifier, etc. are applicable.

  In addition, as said storage battery 30, although storage batteries, such as a lithium ion storage battery, a nickel hydride storage battery, and a lead storage battery, are applicable, other storage batteries, such as a nickel cadmium storage battery, may be sufficient.

FIG. 6A shows an outline of a building power storage system 54 using the storage battery 30. Briefly described with reference to this figure, a solar cell panel 58 for photovoltaic power generation is disposed on the roof portion of the house 56. The solar cell panel 58 is connected to the distribution board 62 via the solar power generation control device 60. The house 56 is provided with a power receiving panel 66 connected to the commercial power system 64. The power receiving board 66 is connected to a distribution board 62, and the distribution board 62 is connected to a plurality of electrical devices (AC loads) via wirings 68A to 68C.

  Furthermore, an indoor control system 70 is disposed in the house 56. FIG. 6B shows a block diagram of the indoor control system 70. As shown in this figure, the indoor control system 70 is connected to the storage battery 30 to control charging / discharging of the storage battery 30 and to manage storage battery 30 temperature and overdischarge / overcharge (SOC). A control device 72 is provided. The storage battery charge / discharge control device 72 is connected to a relay circuit 74. A DC / DC converter 76 and an AC / DC bidirectional converter 78 are connected to the relay circuit 74, and an AC input from the distribution board 62, an AC output to the distribution board 62, and an electric vehicle or a plug-in hybrid vehicle. 80, DC output to a direct current load such as a natural refrigerant heat pump water heater, an LED lighting device, and the like is possible. In addition, a ground detection device 82 is connected to the relay circuit 74, and when it is detected that the ground detection device 82 is grounded, the relay circuit 74 is closed.

The building power storage system 54 is a kind of energy-saving technology that uses the storage battery 30 to store and supply electricity used in the house 56. For example, when this power storage system 54 for buildings is used, electric power obtained by the solar system is stored in the storage battery 30 during the daytime, and late-night power is stored in the storage battery 30 at night, and the daytime charge is high. It can be used such that the power stored in the storage battery 30 is discharged and used.

(Action / Effect)
Next, the operation and effect of this embodiment will be described with reference to the flowchart shown in FIG.

  FIG. 7 shows an outline of the process until the storage battery 30 is housed in the beam member 26 and the building power storage system 54 enters the standby state. As shown in this figure, first, in step 100, the foundation 12 of the house 10 is placed, and the housing 20 of the house 10 is constructed on the foundation 12. In the construction work of the housing 20, the lower end portion of the pillar 22 of the first floor portion 14 is fastened and fixed to an anchor bolt (not shown) standing from the foundation 12, and the upper end portion of the pillar 22 is fixed to the second floor portion 16. The floor beam member 26 is fastened and fixed to the lower flange 26 </ b> C with bolts 48 and nuts 50. Similarly, the lower end portion of the pillar 22 of the second floor portion is fastened and fixed to the upper flange 26B of the beam member 26 of the floor of the second floor portion 16 with bolts 48 and nuts 50, and the upper end portion of the pillar 22 is the ceiling of the second floor portion 16. The beam member 26 is fastened and fixed to the lower flange 26 </ b> C by a bolt 48 and a nut 50.

  Next, in step 102, the storage battery 30 is fixed to the beam member 26 and the ground wire 44 is connected to the fastening portion of the column 22.

  Next, at step 104, it is determined whether or not an external power receiving path such as an external power source such as the solar battery panel 58 or the commercial power system 64 is connected to the indoor control system 70 via the distribution board 62. This determination is made by the storage battery charge / discharge control device 72 of the indoor control system 70. If the determination in step 104 is affirmative, it is determined that there is no disconnection or the like in the external power receiving path and the external power receiving path is normally secured. If the determination in step 104 is negative, this determination is repeated until the disconnection location returns because there is a disconnection location in the external power receiving path.

  On the other hand, if the result in step 104 is affirmative, the process proceeds to step 108, and it is determined whether or not power is input from the outside. That is, depending on the weather or the like, there is a case where solar power generation is not performed or there is a power outage. Therefore, it is determined in step 108 whether or not electric power necessary for storing in the storage battery 30 is generated.

  If the result in Step 108 is negative, the necessary power is not generated. Therefore, the process returns to Step 104. If the result in Step 108 is positive, the required power is generated. It is determined whether or not the ground wire 44 is grounded. Specifically, the determination is made based on whether or not the grounding detection device 82 detects the grounding. If the result in Step 110 is negative, it means that the ground wire 44 has been removed from the fastening location or the like, and the process returns to Step 104. In addition, although it returns to step 104 from a viewpoint of control in the indoor control system 70, it returns to step 102 from a viewpoint of a work procedure.

On the other hand, if the determination at step 110 is affirmative, the routine proceeds to step 112, where the relay circuit 74 of the indoor control system 70 is closed. Thereby, the storage to the storage battery 30 becomes possible.
Here, in this embodiment, since shape steel is used for the beam member 26 and the storage battery 30 is stored in the space 32 provided in the beam member 26, the storage space for the storage battery 30 is expanded. In particular, since the beam member 26 is arranged everywhere as a structural material of the house 10, if the space 32 provided in the beam member 26 can be used as a storage space for the storage battery 30, it will also be an effective use of dead space, There are many advantages.

  Furthermore, since the beam member 26 is a steel material, the heat generated from the storage battery 30 is efficiently transmitted to the beam member 26. Therefore, heat dissipation of the storage battery 30 is promoted.

  As a result, according to the present embodiment, the storage battery 30 can be sufficiently accommodated, and the heat dissipation can be improved.

  In the present embodiment, the storage battery 30 is disposed in contact with or close to the surface of the beam member 26. In other words, the size (one size) in which the height and the depth substantially match the space portion 32 of the beam member 26. Since the storage battery 30 having a smaller size is accommodated, the heat transfer from the storage battery 30 to the beam member 26 compared to the case where a relatively large gap is formed between the storage battery 30 and the beam member 26. The amount increases. As a result, the cooling efficiency of the storage battery 30 can be increased.

  Furthermore, in this embodiment, since the fireproof material layer 52 is formed by covering the constituent surface of the space portion 32 of the beam member 26 in which the storage battery 30 is housed, the fireproof coating layer 52 is formed. Further, it is possible to prevent the storage battery 30 from being damaged by the high heat conduction heat. In addition, when the storage battery 30 abnormally radiates heat, the beam member 26 can be prevented from being damaged by abnormal heat dissipation from the storage battery 30. In normal times, the heat released from the storage battery 30 is dissipated through the beam member 26, so the effect of increasing the efficiency of the storage battery 30 is not impaired. As a result, according to the present embodiment, the storage battery 30 can be protected from high heat during an abnormality, and the beam member 26 can be prevented from being damaged by heat. The efficiency of 30 can be increased.

  Further, in the present embodiment, since the fireproof coating material constituting the fireproof coating layer 52 is made of a material that expands when it reaches a high temperature of a predetermined temperature or more, for this reason, when an abnormality such as when a fire or the like occurs, When the fireproof covering layer 52 expands, it is possible to suppress high-temperature conduction heat from being transmitted to the storage battery 30 and to prevent the storage battery 30 from being damaged. In addition, when the storage battery 30 abnormally radiates heat, the fireproof coating layer 52 expands to prevent the beam member 26 from being damaged by abnormal heat dissipation from the storage battery 30. In addition, since the fireproof coating layer 52 does not expand at normal times, the heat released from the storage battery 30 is dissipated through the beam member 26, and the effect of increasing the efficiency of the storage battery 30 is not impaired. As a result, according to the present embodiment, it is possible to protect the storage battery 30 from high heat at the time of abnormality, and to reduce damage due to heat of the beam member 26 and thus the housing 20.

  Further, in the present embodiment, the storage battery 30 is disposed at a portion of the beam member 26 where the fireproof coating layer 52 is provided. When the surface of the beam member 26 is exposed to a high temperature due to a fire or the like, the surface of the beam member 26 is An expanded fireproof coating layer 52 is interposed between the battery 30 and the storage battery 30. That is, a heat insulating layer is formed between the surface of the beam member 26 and the storage battery 30. For this reason, in the case of an abnormality such as when a fire or the like occurs, the heat insulating layer formed by the expansion of the refractory coating layer 52 suppresses the transfer of high heat conduction heat to the storage battery 30 and damages the storage battery 30. Can be prevented. Further, when the storage battery 30 is abnormally radiated, such as when the battery 30 is abnormally dissipated, the heat insulating layer formed by the expansion of the fireproof coating layer 52 prevents the beam member 26 from being damaged by abnormal heat dissipation from the storage battery 30. can do. In addition, normally, since the fireproof covering layer 52 does not expand and a heat insulating layer is not formed, the heat released from the storage battery 30 is dissipated through the beam member 26, and the effect of increasing the efficiency of the storage battery 30 is not impaired. As a result, according to the present embodiment, the storage battery 30 can be more effectively protected from the high heat at the time of abnormality, and damage due to heat of the beam member 26 and thus the housing 20 can be further reduced.

  Moreover, in this embodiment, since the wiring 42 drawn out from the storage battery 30 is routed along the beam member 26 in the space 32 of the beam member 26, it is not necessary to secure a wiring route specially. For this reason, it is not difficult to secure the wiring path.

  In this embodiment, the storage battery 30 is fixed to the beam member 26 with the bolts 34. However, the present invention is not limited to this, and a fitting structure with claws may be adopted as shown in FIG. In brief, the claw 84 protrudes from the upper end and lower end of the storage battery 30. The claw 84 is formed in a cylindrical shape, and is set to have an outer diameter slightly smaller than the inner diameter of the bolt insertion hole 36 formed in the upper flange 26B and the lower flange 26C of the beam member 26. The tip of the claw 84 is an inclined surface 84A. In addition, a cylindrical recess 86 in which the claw 84 can be stored is formed in the wall portion of the storage battery 30, and a compression coil spring 88 that is a spring member is stored in the recess 86. The lower end portion of the compression coil spring 88 is locked to the bottom surface of the recess 86, and the upper end portion of the compression coil spring 88 is locked to the bottom surface of the claw 84. Therefore, the compression coil spring 88 presses and biases the claw 84 in a direction in which it always protrudes.

  According to the above structure, the claw 84 protrudes from the upper end and the lower end of the storage battery 30 in the state shown in FIG. For this reason, when the storage battery 30 is to be stored in the space 32 of the beam member 26, the inclined surfaces 84A of the upper and lower claws 84 interfere with the side surfaces of the upper flange 26B and the lower flange 26C of the beam member 26, and the storage battery 30 still remains. Is pushed into the space portion 32 side, the claw 84 is pushed toward the bottom surface side of the recess 86 against the urging force of the compression coil spring 88 and retracted. Thereafter, when the claw 84 corresponds to the bolt insertion hole 36 formed in the beam member 26, the claw 84 extends into the bolt insertion hole 36 as shown in FIG. 8B, and the storage battery 30 is fixed to the beam member 26. It will be in the state.

  According to this configuration, a fastener such as a bolt 34 is not necessary, and the storage battery 30 can be fixed to the beam member 26 with a single touch.

  As shown in FIGS. 9 and 10, the second embodiment is characterized in that the storage battery 30 is fixed to the beam member 26 using a fixing member 150.

  Specifically, the fixing member 150 is formed in a U shape in plan view, and includes left and right side portions 150A and an intermediate portion 150B. The heights of the side portions 150A and the intermediate portion 150B are set slightly lower than the height of the space portion 32 of the beam member 26. For this reason, the fixing member 150 can be inserted between the upper flange 26B and the lower flange 26C of the beam member 26.

  In addition, right-sided triangular engagement protrusions 152 are integrally formed on the upper and lower edge portions of the left and right side portions 150A. The engaging protrusion 152 is formed so that the hypotenuse is positioned on the insertion direction side of the fixing member 150. Further, the height of the engagement protrusion 152 is set to a height at which the front end of the engagement protrusion 152 interferes with the side surfaces of the upper flange 26B and the lower flange 26C of the beam member 26.

  Although not shown, screw insertion holes are formed at a plurality of locations in the intermediate portion 150B of the fixing member 150, and correspondingly, the side surface on one side of the storage battery 30 is coaxial with the screw insertion holes. A screw insertion hole is formed. Then, both the screw insertion holes are coaxially positioned, and the screw is screwed from the outside of the intermediate portion 150B of the fixing member 150, whereby the fixing member 150 is fixed to one side surface of the storage battery 30. Yes.

  Moreover, although illustration is abbreviate | omitted, the fireproof coating layer demonstrated in 1st Embodiment is provided also in the inner surface of the said fixing member 150. FIG.

(Action / Effect)
According to the above configuration, the storage battery 30 is fixed to the beam member 26 in the following manner. First, the intermediate portion 150B of the fixing member 150 is fixed to the side surface on one side of the storage battery 30 with a screw. Thereby, the fixing member 150 is integrated with the storage battery 30. When this state is viewed from the side, the state is as shown in FIG. From this state, as shown in FIG. 11B, the fixing member 150 is mounted in the space portion 32 of the beam member 26. At this time, the engaging protrusions 152 formed on the upper and lower edges of both side portions 150A of the fixing member 150 interfere with the side surfaces of the upper flange 26B and the lower flange 26C of the beam member 26, but still the fixing member 150. Is pushed into the space portion 32 of the beam member 26, the tip portions of the two upper and lower sets of engaging projections 152 formed on both side portions 150A of the fixing member 150 are crimped (compressed and deformed by compression plastic deformation). Thereby, the storage battery 30 is fixed in the state accommodated in the space part 32 of the beam member 26.

  Thus, in this embodiment, since the storage battery 30 is fixed between the upper flange 26B and the lower flange 26C of the beam member 26 using the fixing member 150, there is no bolt fastening operation, and the storage battery 30 is attached to the beam member 26. Can be fixed. Therefore, the work of fixing the storage battery 30 to the beam member 26 is facilitated. Further, in the state where the storage battery 30 is fixed, the intermediate portion 150B of the fixing member 150 covers one side surface of the storage battery 30, and the intermediate portion 150B is disposed outside the beam member 26, so that the heat generated from the storage battery 30 Is radiated from the intermediate portion 150B. Therefore, heat dissipation of the storage battery 30 can be promoted and the efficiency of the storage battery 30 can be increased. As a result, according to the present embodiment, workability when fixing the storage battery 30 to the beam member 26 can be improved, and efficiency can be improved by improving heat dissipation of the storage battery 30.

  Moreover, in this embodiment, since the fireproof coating layer demonstrated in 1st Embodiment was provided in the inner surface of the fixing member 150, the heat which generate | occur | produced from the storage battery 30 is interrupted | blocked by the said fireproof coating layer. Therefore, the heat generated from the storage battery 30 hardly reaches a member (for example, a ceiling material or a floor material) disposed near the beam member 26. For this reason, not only the surface of the storage battery 30 outside (the side opposite to the web 26A of the beam member 26) is covered with the intermediate portion 150B of the fixing member 150, but a fireproof coating layer is further provided on the inner surface thereof. In addition, members (for example, ceiling materials and floor materials) arranged near the beam member 26 can be kept well.

  In the present embodiment, the configuration in which the right-angled triangular engagement protrusions 152 are integrally formed on the upper edge portion and the lower edge portion of the both side portions 150A of the fixing member 150 is not limited thereto. As shown in FIG. 12, engagement protrusions 156 having the same shape are integrally formed on the middle part of the upper edge part and the lower edge part of both side parts 154A of the fixing member 154 formed in a U shape in plan view. It may be formed.

[Supplementary explanation of the above embodiment]
