  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The present embodiment exemplifies a building panel (hereinafter, referred to as “interior panel 1”) in which the planar heater 3 </ b> A is incorporated as the electrical device 3.

  The interior panel 1 includes a rectangular panel body 2 and a planar heater 3A incorporated therein.

  As shown in FIG. 1, the panel main body 2 is made of a base material 9, heat insulating materials 10 a and 10 b that are fitted into a recessed portion 11 provided on the surface side of the base material 9, and a wooden or And a resin surface plate 12. The base material 9 is composed of a frame body 19 made of hard foamed resin or wood having self-retaining properties and a back plate 13 lined behind it, or a separate body. Of the heat insulating materials 10a and 10b, the heat insulating material 10a located on the back surface side functions as a reinforcing heat insulating layer such as urethane, and the heat insulating material 10b located on the front surface side functions as a lightweight heat insulating layer made of a vacuum heat insulating material. . In addition, the base material 9 and the reinforcing heat insulating material 10a can be configured integrally, in addition to being configured separately.

  As shown in FIG. 2 (a), the side end portion 13 a of the back plate 13 includes a side end portion of the frame body 19 constituting the base material 9, at one side end portion 2 a on the short side 2 c side of the panel body 2. The side end 12a of the surface plate 12 is disposed so as to substantially overlap the side end 19a of the frame body 19 while projecting outward from 19a.

  Further, a wiring space 8 is formed at one side end 2a of the panel body 2 on the short side 2c side. The wiring space portion 8 is opened to the other side end portions 2b and 2b on the long side on both sides adjacent to the one side end portion 2a and in a direction substantially orthogonal to the one side end portion 2a. Arrows A, C, and C in FIG. 1 indicate the opening direction of the one side end 2a. Thereby, in the state (FIG. 7) where the other end portions 2b, 2b of the plurality of panel main bodies 2 are arranged adjacent to each other in parallel (see FIG. 7), the wiring space portions 8 of each panel main body 2 are arranged in a straight line. It has become.

  In the wiring space 8, transition wires 18, 18 a, 18 b for supplying external power are stored. A storage recess 5 is formed at the center of the wiring space 8 of this example so as to be recessed toward the inside of the panel body 2. The storage recess 5 stores a repeater 4A, which will be described later, so that the relay 4A can be inserted and removed, and the relay 4A can be pulled out between the storage recess 5 and the wiring space 8.

  Further, in the wiring space portion 8, the surplus wiring storage portion 20 (see FIG. 5) is recessed toward the inside of the panel body 2 on both sides of the storage recess 5 in this example, with the storage recess 5 interposed therebetween. 3) is provided, and the surplus portion 18c of the transition wiring 18 (18a, 18b) wired along the wiring space 8 can be stored.

  On the other hand, the planar heater 3A incorporated in the panel body 2 is interposed between the heat insulating material 10b of the panel body 2 and the surface plate 12, as shown in FIG. The planar heater 3A is made of, for example, a PTC heater, which can directly warm a person or a futon while suppressing an increase in room temperature by a windless radiation method, and can save power without wasting heat loss. Safe and clean radiant heating can be realized without overdrying the air and rolling up house dust. In this example, two sheet heaters 3A and 3A are provided, and each sheet heater 3A is electrically connected to a relay 4A constituting the electrical connection portion 4 shown in FIG. The number of planar heaters 3A is not limited to two, but may be one large area planar heater 3A (FIG. 8) or three or more small area planar heaters. These planar heaters 3A are controlled for operation by an operating device (not shown) provided in the room.

  Further, a recess for storing the planar heater 3A and the like of the base material 9 through the wiring groove 31 (FIGS. 2B and 2C) provided in the side end portion 19a of the frame body 19 constituting the base material 9 is provided. The connector 11 provided at the end of the power supply line 17 is communicated with the housing recess 5 and the power supply line 17 from the planar heater 3A is connected along the wiring groove 31. 14 is connected to a connecting portion at the rear end of the relay 4A housed in the housing recess 5. The feeder line 17 is pulled out when the repeater 4A is pulled out, and is pushed in without difficulty when the repeater 4A is pushed in.

  In addition, on one side of the repeater 4A (FIG. 2) of the first-stage panel body 2 arranged closest to the power supply side, there is a connection portion to which the power supply connecting wiring 18 (FIG. 2 (a)) is connected. Provided on the other surface is a connecting portion to which one connector 15 of the crossover wiring 18a is connected. The connecting portion to which the other connector 16 of the above-mentioned transition wiring 18a is connected and one connector 15 of another transition wiring 18b are connected to both surfaces of the second-stage and subsequent repeater 4A (FIGS. 3 and 4). Connecting portion. A connection portion to which the other connector 15 (FIG. 7) of the crossover wiring 18b is connected is provided on one surface of the final-stage repeater 4A. For example, VVF electric wires are used as the crossover wires 18, 18a, 18b.

  Further, in the vicinity of the storage recess 5 for storing the repeater 4A, as shown in FIGS. 2B and 2C, the connector 15 (16) of the crossover wiring 18a (18b) connected to the repeater 4A is provided. A connector fitting recess 6 is provided in accordance with the outer shape. This connector fitting recess 6 prevents incomplete connection so that the connector 15 (16) can be fitted into the connector fitting recess 6 only when the connector 15 (16) is securely connected to the relay 4A. Configure the means.

  Next, an example of a construction procedure in the case where the interior panel 1 having the above configuration is attached to a part of the ceiling surface 30 as shown in FIG. 5 will be described.

  First, as shown in FIG. 6A, a plurality of panel main bodies 2 before wiring are fixed on the mounting surface 30 with fixing screws in a state where they are arranged adjacent to each other in parallel. Thereafter, wiring work is performed from the indoor side to the repeater 4 </ b> A of each panel body 2. That is, as shown in FIG. 2C, the connector 15 of the wiring 18a is connected to the connecting portion on one side of the relay 4A in a state where the relay 4A is pulled out from the storage recess 5 through the wiring space 8. . Note that, for example, either the transition wiring 18 shown in FIG. 2A or the connector 16 of the transition wiring 18b shown in FIG. Thereafter, as shown in FIG. 2 (b), the relay 4 </ b> A is pushed into the storage recess 5. In this way, the connecting wires 18, 18a, 18b are sequentially connected to the respective relays 4A of the panel bodies 2 (FIG. 7). Finally, as shown in FIGS. 6 (b) and 6 (c), the wiring cover 8 of each panel body 2 is covered with an end cover 21 serving as a peripheral edge to complete the operation.

  Thus, after the panel body 2 having the above configuration is mounted on the mounting surface 30, the wiring lines 18, 18a, 18b can be wired from the indoor side along the wiring space 8 of the panel body 2 and the relay 4A. Can be easily connected. Therefore, the construction work of the panel body 2 and the electric wiring work of the planar heater 3A can be separated, and each work can be performed regardless of the relationship. And since the interior panel 1 which incorporates the planar heater 3A is light, the workability and safety | security to the attachment surface 30 can be ensured, and design property improves further by thin shape. In addition, since it can be retrofitted to the ceiling or the like, there is an advantage that it is possible to easily cope with the transfer and expansion of the interior panel 1.

  In addition, since the wiring space portion 8 in this example is opened not only in the three directions A, C, and C but also in the front direction B (FIG. 2A), the panel body 2 is attached to the attachment surface 30 in the state. Since the wiring space portion 8 is opened not only in the horizontal direction but also in the downward direction, wiring work from below can be performed more smoothly even if not a skilled worker. Moreover, when the connection of the crossover wiring 18a (18b) to the repeater 4A is incomplete, a gap G is generated between the repeater 4A and the connector 15 (16) as shown in FIG. Since (16) does not fit into the connector fitting recess 6 and consequently cannot be pushed back in the direction of the arrow d, a connection failure can be easily confirmed during the work.

  Further, since the surplus wiring 18, 18 a, 18 b has a surplus portion 18 c, it can be connected to the repeater 4 </ b> A with a margin, and the surplus provided in the middle of the wiring space 8 after the connection. Since it can be stored in the wiring storage unit 20, the surplus portion 18 c does not protrude outside the panel body 2. Further, after the wiring, the wiring space portion 8 is covered with the end cover 21 serving as a peripheral edge, so that the relay 4A and the crossover wires 18, 18a, 18b are not exposed to the outside. In addition, since it is not necessary to provide a working opening for performing wiring work on a part of the surface plate 12 of the panel body 2, the appearance of the interior panel 1 as a whole is further improved.

  7 is not limited to the crossover wiring structure on both opposing sides of the panel body 2, and for example, a single-sided crossover wiring structure as shown in FIG. 8 may be used.

  Next, an example of the attachment structure of the end cover 21 will be specifically described with reference to FIGS. Parts other than the attachment structure of the end cover 21 are the same as those in the above embodiment, and corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 9 and 10, the end cover 21 as a peripheral edge covers the wiring space 8 of the panel body 2, and the long vertical piece 26 and the horizontal piece 27 have an L-shaped cross section. Are integrally formed. The end cover 21 of this example is formed by extrusion molding using a known extruder. In addition, formation by injection molding, such as a synthetic resin and aluminum, is also possible.

  The end cover 21 is attached to the panel body 2 using the attaching means 7 (FIG. 15).

  The attachment means 7 includes a panel-side fitting portion 40 of the panel body 2, a groove portion 23 of the end cover 21, and an end cover attachment tool 22. Hereinafter, it demonstrates in order.

  As shown in FIG. 10A, a panel-side fitting portion 40 is projected from a part of the wiring space portion 8 of the panel body 2. The panel side fitting part 40 of this example protrudes from two places on the left and right sides of the housing recess 5 in the wiring space 8. Each panel side fitting part 40 consists of a pair of upper and lower claw parts 40a, 40b (FIG. 15) extending in parallel to each other in the lateral direction P.

  As shown in FIG. 11B, a groove 23 is formed in the inner surface 26 a of the vertical piece 26 of the end cover 21 over the entire length in the length direction R of the end cover 21. The groove portion 23 is composed of a pair of upper and lower L-shaped projecting pieces 23a and 23b (FIG. 15) that extend in parallel to each other in the lateral direction P at a position that does not interfere with the panel-side fitting portion 40.

  The end cover fixture 22 is plugged into the groove 23. As shown in FIG. 11 (b), the end cover attachment 22 includes an insertion portion 24 that is fitted and inserted into the groove portion 23 from one end portion 21 a in the length direction R of the end cover 21, and the insertion portion 24. A cover-side fitting portion 25 that can be slidably fitted to the panel-side fitting portion 40 from the insertion direction (lateral direction P) is integrally formed. The insertion portion 24 of this example is formed in an elongated plate shape having a length of about 1/3 of the entire dimension of the groove portion 23, and a grip piece that can be grasped by hand at the base end portion of the insertion portion 24. 28 and an end cap 29 for covering the open end surface of the wiring space 8 can be attached to the outer surface of the handle piece 28. The handle piece 28 has a smaller diameter than the inner diameter dimension of the wiring space 8, and a wiring hole 28 a is formed in the center.

  At the distal end side of the insertion portion 24, a cover side fitting portion 25 that slide-fits to either one of the panel side fitting portions 40 protruding from the left and right portions of the wiring space portion 8 is provided. Yes. The cover side fitting portion 25 of this example is composed of a pair of upper and lower square bent pieces 25 a and 25 b (FIG. 15) standing from both sides in the width direction of the insertion portion 24, and the claw portion 40 a of the panel side fitting portion 40. , 40b so as not to deviate in the front direction Q perpendicular to the lateral direction P.

  Thus, after the panel body 2 is mounted on the wall or ceiling mounting surface 30 with fixing screws, the crossover wiring work is performed in the wiring space 8. Here, as shown in FIG. 12, the holding member 32 is pulled out from the housing recess 5 in the center of the wiring space 8 and both connectors for the crossover wiring 18a are connected to the relay 4A held by the holding member 32. 15 and 16 are connected to each other, and the holding member 32 is pushed in the direction of the arrow S to house the repeater 4A in the housing recess 5 (state shown in FIG. 10A). The holding member 32 of this example is integrally provided with a grip portion 32a at the tip and a plate-like portion 32b that holds the relay 4A, and is configured by bending a metal plate, a resin plate, or the like. In the following FIGS. 13 to 15, the illustration of the crossover wiring 18 a is omitted.

  After the transition wiring is completed, the wiring space 8 is covered with the end cover 21. That is, a state in which the lower end of the vertical piece 26 of the end cover 21 is along the upper front surface of the surface plate 12 of the panel body 2 and the rear end of the horizontal piece 27 is along the upper end surface of the substrate 9 of the panel body 2 ( 15), when the insertion portion 24 of the end cover attachment 22 is inserted into the groove portion 23 from the one end portion 21a of the end cover 21 as shown in FIG. The joining portion 25 is slidably fitted to the panel side fitting portion 40 from the lateral direction P. Similarly, the insertion part 24 of another end cover attachment 22 is inserted from the other end part 21 b of the end cover 21, and the cover side fitting part 25 is slid with respect to the other panel side fitting part 40. It is made to fit (state of FIG. 11, FIG. 14). In this slide fitting state, as shown in FIG. 15, the upper and lower bent pieces 25 a and 25 b of the cover side fitting portion 25 are detached from the upper and lower claws 40 a and 40 b of the panel side fitting portion 40 in the front direction Q. The end cover 21 can be easily attached to the panel body 2 with the wiring space 8 secured inside the end cover 21.

  In addition, since it is not necessary to fix the end cover 21 to the panel body 2 with screws or the like, the appearance of the end cover 21 is not deteriorated due to the exposure of the screws, and at the same time, the screw fixing work can be omitted. The end cover 21 is attached to the panel main body 2 quickly.

  Further, since the end cover 21 has a cross-sectional shape in which the groove 23 is formed in the entire length in the length direction R, it can be formed by extrusion molding, and the investment in the mold (mold cost) can be suppressed. Since the cross-sectional shape is constant regardless of where it is cut, it can be used after being cut to a predetermined length according to the size of the panel body 2, and one type of end cover 21 can accommodate different panel body 2 sizes. is there.

  Further, when the screw fixing portion 50 (FIG. 10) of the panel body 2 is provided in a part of the wiring space portion 8, even if the screw head of the fixing screw protrudes, the end cover mounting tool 22 is used. Since the end cover 21 having an L-shaped cross section can be attached to the panel body 2 so as not to interfere with the screw fixing portion 50 (FIG. 10), interference between the screw head of the panel body 2 and the end cover 21 is avoided. The space portion 8 for wiring can be secured, thereby preventing interference between the screw head and the end cover 21, and as a result, a non-interference space for avoiding interference with the screw head is formed in the end cover 21 by machining. There is also an advantage that it is not necessary to form and the labor of processing the end cover 21 can be omitted.

  In addition, as an example of use of the end cover 21 of this example, not only the use for one panel main body 2 but also a plurality of panel main bodies 2 are arranged adjacent to each other as shown in FIGS. In the cross wiring structure in which the wiring space portions 8 of each panel body 2 are continuously arranged in a straight line, the wiring space portion 8 is covered with the end cover 21 for each panel body 2. In this case, the handle piece 28 is not attached to the handle piece 28 of the end cover attaching tool 22 used for attaching the end cover 21 to the panel body 2 on the center side. By connecting the end cap 29 to the handle piece 28 of the end cover mounting tool 22 located on the outermost side, the wiring space 8 between the wiring spaces 8 can be routed through the 28 wiring holes 28a. The open side end surface of the outermost wiring space 8 can be closed.

  Moreover, although each said embodiment demonstrated the case where the interior panel 1 was attached to a part of ceiling surface as a ceiling radiant heating panel, it attaches to a part of wall surface, and the use as a wall radiant heating panel is also possible. Furthermore, the interior panel 1 itself can be used as a ceiling structure material or a wall structure material.

  Moreover, although the planar heater 3A was illustrated as the electric equipment 3, it is not restricted to this, The electric heater provided exposed to the exterior of the panel main body 2 may be sufficient, and also it has various facilities of illumination and sound It may be.
