Description

[Technical Field]

[0001] The present invention relates to a method for installing a wiring room in a building, and a wiring room unit. [Background technology]

[0002] A building with multiple floors is provided with a space for passing cables such as power lines and signal lines vertically across multiple floors, known as an EPS (Electric Pipe Shaft). Each floor of the building is also provided with a wiring room to which cables passing through the EPS are connected. For example, a wiring room includes a space used as an EPS on that floor. A wiring room is also called an EPS room or an electrical room. A relay device, such as a distribution board or terminal board, that relays power supply or communications is installed in the wiring room. The cables passing through the EPS and the cables connecting to each part of the floor are connected via the relay device. Power is supplied to each part of the floor and communications are carried out via the wiring room. Patent Document 1 discloses a wiring room. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-137645 Summary of the Invention [Problem to be solved by the invention]

[0004] A wiring room is constructed in the following order: In the first step, architectural work constructs the columns, beams, floors, and exterior walls of each floor of the building. In the second step, architectural work constructs the walls, ceilings, etc. of each floor. At this time, the walls for the wiring room are also constructed, and the space for the wiring room is secured. In the third step, electrical work installs relay devices such as distribution boards, various devices such as lighting, and cables in the space for the wiring room, thereby constructing the wiring room. For example, relay devices are fixed to the walls inside the wiring room. However, because wiring rooms are small rooms, the architectural work to build the walls for the wiring room tends to be postponed and fall behind schedule. This delays the start of the electrical work (third step), which is performed after the architectural work (first and second steps) is completed, and the electrical work is required to be completed within a short period of time, resulting in increased labor costs, increased overtime hours, and a decline in construction quality.

[0005] The present invention was made in consideration of the above circumstances, and its purpose is to provide a wiring room construction method and wiring room unit that allow electrical work to be started early to build a wiring room. [Means for solving the problem]

[0006] The wiring room construction method of the present invention is a method for constructing a wiring room within a building, characterized in that a box-shaped frame having a size equivalent to the size of the space within the wiring room is installed at the location where the wiring room is to be constructed before the walls of the wiring room are constructed, and a relay device for relaying power supply or communications is installed inside the box-shaped frame.

[0007] The wiring room unit of the present invention has a size equivalent to the size of the space inside the wiring room of a building, and is characterized by comprising a box-shaped frame that is installed at the location where the wiring room is to be constructed, and a relay device that is installed inside the box-shaped frame and relays power supply or communications.

[0008] In one embodiment of the present invention, before the walls of a wiring room are constructed within a building, a box frame is installed at the location where the wiring room is to be constructed, and a relay device such as a distribution board is installed inside the box frame. The walls of the wiring room can be constructed later outside the box frame. This allows electrical work to be started before the walls are constructed within the building, allowing for an early start to the electrical work. [Effects of the Invention]

[0009] According to the present invention, it is possible to start electrical work for constructing a wiring room early, thereby ensuring a longer period during which electrical work can be carried out, and other excellent effects of the present invention are achieved.

[0011] The present invention will now be described in detail with reference to the drawings showing embodiments thereof. Fig. 1 is a schematic cross-sectional view of a building 1 having multiple floors. The building 1 is provided with an EPS 11, which is a space for passing a primary cable 12 such as a power line or a communication line in the vertical direction. A through hole 14 for passing the primary cable 12 in the vertical direction is formed in a floor 13 of each floor. The through holes 14 on each floor are provided at approximately the same position when viewed vertically, and multiple through holes 14 are lined up vertically. The multiple through holes 14 lined up vertically are included in the EPS 11.

[0012] A wiring room 2 is provided on each floor of the building 1. The wiring room 2 includes a space used as an EPS 11 on each floor. The wiring room 2 is also called an EPS room or an electrical room. A relay device 21 that relays power supply or communications, such as a distribution board or terminal board, is installed in the wiring room 2. The relay device 21 may relay power supply and communications. The primary side cable 12 arranged through the EPS 11 is connected to the relay device 21. Note that the wiring room 2 may be located in a different position from the EPS 11.

[0013] The secondary cables 22 arranged on each floor are connected to the relay device 21. The relay device 21 relays power supply or communication. That is, the relay device 21 supplies power supplied through the primary cables 12 to various devices connected to the secondary cables 22. The relay device 21 also relays communication through the primary cables 12 by devices connected to the secondary cables 22. The relay device 21 may also relay communication between multiple devices connected to multiple secondary cables 22.

[0014] In the construction method for the wiring room 2 according to this embodiment, electrical work for constructing the wiring room 2 begins before the walls for the wiring room 2 are constructed in the building 1. FIG. 2 is a schematic diagram showing a floor 13 of the building 1 before walls are installed inside the building 1. No walls have yet been installed above the floor 13. Furthermore, through-holes 14 for passing the primary cables 12 are formed in the floor 13. The location of the wiring room 2 to be constructed is determined when the building 1 is designed. That is, the location of the wiring room 2 is determined in advance. In FIG. 2, the location 15 of the wiring room 2 to be constructed is indicated by a dashed line. In the example shown in FIG. 2, the location 15 of the wiring room 2 is an area of ​​a certain size that includes the location where the through-hole 14 is provided. In an embodiment in which the wiring room 2 is constructed in a location different from the EPS 11, the location 15 of the wiring room 2 is in a location different from the location where the through-hole 14 is provided.

[0015] In the construction method for the wiring room 2 according to this embodiment, first, a box-shaped frame 3 is installed at the position 15 of the wiring room 2 to be constructed. FIG. 3 is a schematic perspective view showing an example of the box-shaped frame 3. FIG. 3 shows an example of the box-shaped frame 3 installed at the position 15 of the wiring room 2 to be constructed. The box-shaped frame 3 is configured into a box shape by combining multiple linear frames. The box-shaped frame 3 has a size equivalent to the size of the space inside the wiring room. Furthermore, the size of the box-shaped frame 3 is set to fit within the position 15 of the wiring room 2 to be constructed. The inside of the box-shaped frame 3 is a space where objects can be installed and where people can work.

[0016] The box-shaped frame 3 is constructed by combining multiple rectangular frames 31. FIG. 4 is a schematic diagram showing an example of the rectangular frame 31. The rectangular frame 31 is composed of linear frames 32 having a linear shape. For example, the linear frames 32 are made of metal, resin, wood, or the like. The rectangular frame 31 is created by combining multiple linear frames 32 into a rectangle. The multiple linear frames 32 are joined to each other. For example, the multiple linear frames 32 are joined to each other using bolts, connecting metal fittings, adhesive, or the like. If the linear frames 32 are made of metal, the multiple linear frames 32 may be joined to each other by welding.

[0017] The multiple rectangular frames 31 are prepared in advance before electrical work to construct the wiring room 2 begins. During the electrical work, the multiple rectangular frames 31 are brought into the building 1 and combined into a box shape at the location 15 of the wiring room 2 to be constructed. In addition to the multiple rectangular frames 31, a linear frame 32 is used to assemble the box-shaped frame 3. The multiple rectangular frames 31 and the linear frame 32 are joined to each other. For example, the multiple rectangular frames 31 and the linear frame 32 are joined to each other using bolts, connecting metal fittings, adhesive, or the like. If the rectangular frames 31 and the linear frame 32 are made of metal, they may be joined by welding. The box-shaped frame 3 may be assembled using additional members other than the multiple rectangular frames 31 and the linear frame 32.

[0018] When assembling the box-type frame 3, multiple rectangular frames 31 are combined, which simplifies the work of assembling the box-type frame 3 compared to assembling the box-type frame 3 by combining linear frames 32. There is no need to create the rectangular frames 31 after the electrical work to construct the wiring room 2 has begun; instead, rectangular frames 31 that have been created in advance can be used, so the time required to assemble the box-type frame 3 at the construction site is short. This reduces the time required to construct the wiring room 2.

[0019] The box frame 3 is fixed to the floor 13. For example, the box frame 3 is fixed to the floor 13 using anchor bolts that are pre-embedded in the floor 13. The box frame 3 may also be fixed to a structure of the building 1 other than the floor 13. For example, the box frame 3 may be fixed to a wall, column, or beam of the building 1.

[0020] In the construction method for the wiring room 2, next, the equipment required for the wiring room 2 is installed inside the box frame 3. FIGS. 5 and 6 are schematic perspective views showing an example of the box frame 3 and the equipment installed inside the box frame 3. FIG. 5 shows a diagram in which the primary cable 12 and the secondary cable 22 are omitted. A relay device 21 is installed inside the box frame 3. The relay device 21 is, for example, a distribution board or a terminal board. FIG. 6 shows a state in which the primary cable 12 and the secondary cable 22 are connected to the relay device 21. FIGS. 5 and 6 show an example in which two relay devices 21 are installed. Only one relay device 21 may be installed inside the box frame 3, or three or more relay devices 21 may be installed.

[0021] The distribution board is connected to a primary cable 12, which is a power line, and is also connected to secondary cables 22, which are power lines connected to multiple locations within the building 1. The distribution board is provided with circuits for connecting, disconnecting, switching, etc. between the primary cable 12 and each secondary cable 22, and relaying the power supply. The distribution board connects the primary cable 12 to any of the secondary cables 22, and relays the power supply. Current flows from the primary cable 12 to the secondary cable 22 via the circuits within the distribution board, and power is supplied to each location within the building 1.

[0022] The terminal board is connected to the primary cable 12, which is a communication line, and is also connected to secondary cables 22, which are communication lines connected to multiple locations within the building 1. The terminal board is provided with a circuit for connecting the primary cable 12 to each secondary cable 22 and relaying the communication. The terminal board may also be provided with a circuit for connecting multiple secondary cables 22, which are communication lines. The terminal board connects the primary cable 12 to any one of the secondary cables 22, or connects multiple secondary cables 22 together, and relays communication for sending and receiving various data or signals, such as web data, device control signals, or audio signals.

[0023] The relay device 21 is installed inside the box-shaped frame 3 and fixed to the box-shaped frame 3. For example, the relay device 21 is fixed to any of the linear frames 32 included in the box-shaped frame 3 using bolts, connecting metal fittings, adhesive, or the like. By fixing the relay device 21 to the box-shaped frame 3, the relay device 21 can be fixed in the same way as in a conventional wiring room where the relay device is fixed to a wall.

[0024] In addition, in the construction method of the wiring room 2, a cable support member 23 is installed inside the box frame 3. The cable support member 23 is a facility for arranging and fixing multiple primary cables 12. The cable support member 23 is, for example, a metal cable rack configured in a long ladder shape. The cable support member 23 is arranged so that its longitudinal direction is the vertical direction. As shown in FIGS. 5 and 6 , the vertical length of the cable support member 23 may be longer than the vertical length of the box frame 3. The cable support member 23 may pass through the through holes 14 and be installed across multiple floors, or may be installed individually on each floor. When installed individually on each floor, the cable support member 23 is installed near the through holes 14. The cable support member 23 is fixed to the box frame 3. For example, the cable support member 23 is fixed to any of the linear frames 32 included in the box frame 3 using bolts or connecting metal fittings.

[0025] The multiple primary cables 12 arranged through the EPS 11 pass through the through-hole 14 and inside the box frame 3. The multiple primary cables 12 are bundled together and arranged inside the box frame 3 along the cable support member 23. The multiple primary cables 12 may be arranged in one or more bundles. The multiple primary cables 12 may be fixed to the cable support member 23 along the cable support member 23. For example, the primary cables 12 are fixed to the cable support member 23 with a tying band.

[0026] Some of the multiple primary cables 12 are connected to relay devices 21. For example, the primary cables 12 that are power lines are connected to the relay device 21 that is a distribution board, and the primary cables 12 that are communication lines are connected to the relay device 21 that is a terminal board. There may be relay devices 21 to which no primary cables 12 are connected. Some of the multiple primary cables 12 extend to other floors. By installing the multiple primary cables 12 along the cable support member 23, the multiple primary cables 12 are arranged in an organized manner within the wiring room 2, without being arranged in a disorderly manner.

[0027] FIG. 7 is a schematic diagram showing a relay device 21 to which a primary cable 12 and a secondary cable 22 are connected. The relay device 21 includes a device main body 211 including a circuit for relaying power supply or communication. The relay device 21 also includes a primary lead-out wire 212 and a secondary lead-out wire 213 connected to the circuit included in the device main body 211. The primary lead-out wire 212 and the secondary lead-out wire 213 are provided in the relay device 21 before electrical work begins. The primary lead-out wire 212 is a cable to which the primary cable 12 is connected, and the secondary lead-out wire 213 is a cable to which the secondary cable 22 is connected. A connecting component such as a connector for connecting the primary cable 12 is coupled to the primary lead-out wire 212, and the primary cable 12 is connected to the primary lead-out wire 212 via the connecting component. Similarly, a connection part to which the secondary cable 22 is connected is coupled to the secondary lead wire 213, and the secondary cable 22 is connected to the secondary lead wire 213 via the connection part. By connecting the primary cable 12 to the primary lead wire 212 and the secondary cable 22 to the secondary lead wire 213, the primary cable 12 and the secondary cable 22 are connected to the relay device 21. Compared to connecting the primary cable 12 and the secondary cable 22 directly to the circuits in the installed relay device 21, the work of connecting the primary cable 12 and the secondary cable 22 to the relay device 21 is simpler. This reduces the time required to construct the wiring room 2.

[0028] A plurality of cable support members 23 may be arranged inside the box-type frame 3. Cable support members 23 whose longitudinal direction is in a direction other than the vertical direction may be arranged. For example, cable support members 23 whose longitudinal direction is in a horizontal direction that intersects the vertical direction may be arranged. In a configuration in which the wiring room 2 is constructed in a position different from the EPS 11, the plurality of primary cables 12 that pass through the through holes 14 are extended to a position 15 of the wiring room 2 and connected to a relay device 21 inside the box-type frame 3.

[0029] An additional frame 33 can be attached to the box-shaped frame 3. The additional frame 33 is attached to one of the rectangular frames 31. FIG. 8 is a schematic diagram showing an example of a rectangular frame 31 with an additional frame 33 attached. The additional frame 33 is a linear frame and is arranged in the vertical direction. For example, the additional frame 33 is made of metal, resin, wood, or the like. The additional frame 33 is attached to the rectangular frame 31 so as to connect two parallel linear frames 32 included in the rectangular frame 31. The additional frame 33 is fixed to the two linear frames 32. For example, the additional frame 33 is fixed to the linear frame 32 using bolts, connecting metal fittings, adhesive, or the like.

[0030] The additional frame 33 can be fixed at any position along the two linear frames 32. That is, the additional frame 33 can be moved as needed. The additional frame 33 can be attached between any two linear frames 32 that are adjacent and parallel to each other in the horizontal direction. The additional frame 33 can also be attached to any rectangular frame 31. That is, the additional frame 33 can be attached to any position on the box-shaped frame 3. Multiple additional frames 33 may be attached to the box-shaped frame 3. The additional frames 33 may be arranged along the horizontal direction. In this embodiment, the additional frame 33 is attached between two linear frames 32 that are adjacent and parallel to each other in the vertical direction.

[0031] Devices 24 other than the relay device 21 may be installed inside the box-type frame 3. For example, the devices 24 are lights, switches, outlets, pipes with power lines inside, circuit breakers, relays, watt-hour meters, transformers, standby power supplies, control devices, etc. The relay device 21 and the devices 24 may be connected by power lines or communication lines. The devices 24 are fixed to the box-type frame 3. For example, the devices 24 are fixed to any of the linear frames 32 included in the box-type frame 3 using bolts, metal connectors, adhesives, etc. Some of the devices 24 may be fixed to the linear frames 32 in advance.

[0032] The relay device 21 or the device 24 may be fixed to the additional frame 33. Depending on the location where the relay device 21 or the device 24 is installed, there may be no linear frame 32 to fix the relay device 21 or the device 24. For example, if the relay device 21 or the device 24 is installed in a location away from any linear frame 32, there will be no linear frame 32 to fix the relay device 21 or the device 24. Since the additional frame 33 can be attached to any position on the box-type frame 3, even if there is no linear frame 32 to fix the relay device 21 or the device 24, the additional frame 33 can be placed near the relay device 21 or the device 24. The relay device 21 or the device 24 can be fixed to the additional frame 33 placed near the relay device 21 or the device 24. For example, the relay device 21 or the device 24 is fixed to the additional frame 33 using bolts, connecting metal fittings, adhesive, or the like.

[0033] The relay device 21 or the device 24 can be installed in any position by placing the additional frame 33 near the relay device 21 or the device 24 and fixing the relay device 21 or the device 24 to the additional frame 33. This allows the relay device 21 or the device 24 to be installed in an appropriate position inside the box-type frame 3. It also makes it possible to install as many relay devices 21 or devices 24 as possible inside the box-type frame 3.

[0034] As shown in Fig. 6, the box-shaped frame 3 and the equipment installed inside the box-shaped frame 3 are collectively referred to as the wiring room unit 20. When the wiring room unit 20 is completed, the functionality of the wiring room 2 can be realized.

[0035] The interior walls of the building 1 are constructed outside the box frame 3. Figure 9 is a schematic perspective view showing an example of a wiring room 2 with walls. A wall 16 is built on the floor 13. Part of the wall 16 forms the wall of the wiring room 2, and the wiring room unit 20 is covered by the wall 16. A door 25 is provided in part of the wall 16. The door 25 leads to the inside of the box frame 3. The inside of the box frame 3 is the interior of the wiring room 2. In other words, people can enter and exit the wiring room 2 through the door 25.

[0036] By constructing the walls 16 on the outside of the box frame 3, the walls of the wiring room 2 can be constructed and the wiring room 2 can be completed. The work of constructing the walls 16 can be performed independently of the work of installing equipment inside the box frame 3. The work of constructing the walls 16 may be performed after the wiring room unit 20 is completed, or may be performed in parallel with the work of installing equipment inside the box frame 3.

[0037] As described above in detail, in this embodiment, before the walls of the wiring room 2 are constructed, the box frame 3 is installed at the location 15 of the wiring room 2 to be constructed, and the equipment necessary for the wiring room 2, such as the relay device 21, is installed inside the box frame 3. This makes it possible to start electrical work to construct the wiring room 2 before the walls are constructed inside the building 1, allowing the electrical work to begin earlier. This makes it possible to secure a longer period of time for carrying out electrical work than before. The work for electrical work can be distributed over time, thereby leveling out the workload. This makes it possible to prevent increases in labor costs, increases in overtime hours, and declines in construction quality.

[0038] In this embodiment, the box frame 3 is fixed to the structure of the building 1, but the box frame 3 may be unfixed. Also, the relay device 21 may be unfixed to the box frame 3. In this embodiment, the wall 16 is constructed on the outside of the box frame 3, but the wiring room unit 20 may be used as the wiring room 2 without constructing the wall 16. The wiring room unit 20 may include a floor for the wiring room 2 that is separate from the floor 13 of the building 1. The floor of the wiring room 2 has a size that can fit inside the wiring room 2 and is placed on the floor 13, and the box frame 3 is installed on the floor of the wiring room 2. For example, the floor of the wiring room 2 is fixed to the floor 13, and the box frame 3 is fixed to the floor of the wiring room 2.

[0039] In this embodiment, the box frame 3 is assembled from the rectangular frame 31 at the construction site. However, the box frame 3 may also be assembled from the linear frame 32 at the construction site. In this embodiment, the box frame 3 does not include the rectangular frame 31 but includes multiple linear frames 32, and the additional frame 33 may be attached to any two of the linear frames 32. Alternatively, the box frame 3 may be assembled outside the building 1, and the pre-assembled box frame 3 may be transported into the building 1. The transported box frame 3 is installed and fixed at the position 15 of the wiring room 2. Transporting the pre-assembled box frame 3 into the building 1 eliminates the need to assemble the box frame 3 inside the building 1, thereby reducing the time required to construct the wiring room 2.

[0040] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. In other words, embodiments obtained by combining technical means modified appropriately within the scope of the claims are also included in the technical scope of the present invention.
