Then, the screw 121a can be easily detached from the second screw holding portion 124 by pushing the shaft portion of the screw 121a from the outer surface of the bottom wall 111a to the front side through the hole 124b near the base end of the protrusion 124a.

  Further, in the present embodiment, a pair of screw holes 123 are formed on both sides of the fixing hole 113 of the wiring box bottom wall 111a. The pair of screw holes 123 are arbitrarily used to fix the wiring box 110 to the fixed portion with screws.

  As shown in FIGS. 3B and 3C, pin-like protrusions 116 protrude outward from the four corners of the outer surface of the bottom wall 111 a of the wiring box 110. The protrusion 116 is formed integrally with the wiring box bottom wall 111a. The protruding portion 116 is configured to be able to bite into the heat insulating board 130 which is a fixed portion and engage with the heat insulating board 130. It is sufficient that at least one protruding portion 116 is provided, and functions to lock the rotation of the wiring box 110 in cooperation with the screw 150, as will be described later. On the other hand, as shown in FIG. 3A, fitting holes 117 are provided at the four corners of the opening edge portion 112a of the wiring box 110, respectively. The four fitting holes 117 are arranged at positions corresponding to the four protruding portions 116. Each fitting hole 117 has a size corresponding to each protrusion 116. That is, as shown in FIG. 5, when a plurality of wiring boxes 110 are stacked, the protrusions 116 are fitted into the fitting holes 117 and are stacked so as not to deviate from each other. Thereby, it is possible to save the space at the time of storage and shipment of the wiring box 110.

  In addition, the wiring box 110 of this embodiment is formed from a synthetic resin. However, the material and shape dimensions of the wiring box of the present invention are not limited to the above embodiment, and can be arbitrarily selected by those skilled in the art.

  Next, with reference to FIG. 6, the heat insulation board 130 of the wiring apparatus 100 of one Embodiment of this invention is demonstrated. As shown in FIG. 6, the heat insulation board 130 is formed in a rectangular parallelepiped shape with a heat insulation material such as a rectangular parallelepiped foamed plastic or foamed rubber. The heat insulation board 130 is preferably formed of a hard foam material so as not to be pressed and deformed by a force when being fixed to the construction surface W with the screws 150. For example, in this embodiment, the heat insulating board 130 is made of rigid polyurethane foam. The heat insulating board 130 preferably has substantially the same shape (dimensions) as the wiring box bottom wall 111b in the front and rear surface shapes. Further, the thickness of the heat insulating board 130 is the distance between the construction surface W1 and the inner wall W3 (standing) along with the thickness of the wiring box 110 (the distance from the opening edge 112a to the bottom surface of the bottom wall 111a). Is preferably set to be equal. That is, the interposition of the heat insulating board 130 reduces a decrease in heat insulating performance at the installation location of the wiring box 110. Furthermore, double-sided adhesive layers 131 and 132 are attached to the front and rear surfaces of the heat insulation board 130, respectively. By these double-sided adhesive layers 131 and 132, the front and rear surfaces of the heat insulation board 130 are respectively adhered to the outer surface of the bottom wall 111b of the wiring box 110 and the construction surface W1, and the connection by the screws 150 is assisted. Before installation of the wiring box 110 and the heat insulation board 130, a release sheet 133 is attached to the double-sided adhesive layers 131 and 132 for convenience.

  In the present embodiment, the double-sided adhesive layers 131 and 132 simply (or temporarily) adhere the heat insulation board 130 to the wiring box 110 and the construction surface W1 in order to facilitate the installation work of the wiring box 110. Used to do. Finally, since it is sufficient to connect the wiring box 110 to the heat insulation board 130 and the construction surface W1 with the screws 150, the double-sided adhesive layer 131 on the front side may be omitted. On the other hand, the double-sided adhesive layer 132 on the rear surface side that bonds the heat insulation board 130 and the construction surface W1 prevents the heat insulation board 130 from rotating around the screw 150 with respect to the construction surface W1 during or after installation. It also functions as a rotation prevention means.

  FIG. 7 shows a wiring structure 10 in which the wiring device 100 and the wiring box 110 of this embodiment are installed between the construction surface W1 and the inner wall W3. In the present embodiment, the construction surface W1 is an inner wall surface of a concrete outer wall constituting the building, and the inner wall W3 is a finished wall made of a plaster board or a plywood board. And in order to ensure desired heat insulation performance between the wall surface space and the outside environment, a heat insulating layer W2 having a predetermined thickness is provided over the entire surface in the wall space between the construction surface W1 and the inner wall W3. ing. The thickness of the heat insulating layer W2 is substantially equal to the distance between the construction surface W1 and the back surface of the inner wall W3. The heat insulating layer W2 is made of a foamed resin such as foamed polyurethane. In addition, this invention is not limited to this form, You may form the heat insulation layer W2 only around the heat insulation board 130. FIG.

  As shown in FIG. 7, the wiring device 100 is installed in the wall space, and the wiring box 110 and the heat insulation board 130 are fixed to the construction surface W1 with screws 150. The opening edge 112a of the opening 112 of the wiring box 110 is disposed so as to substantially contact the back surface of the inner wall W3. Moreover, the heat insulation board 130 is located between the wiring box 110 and the construction surface W1. More specifically, the front surface of the heat insulation board 130 contacts (adheres) to the outer surface of the bottom wall 111a of the wiring box 110 through the double-sided adhesive layer 131, and the rear surface thereof contacts the construction surface W1 through the double-sided adhesive layer 132. Contact (adhesion). And the wiring box side wall 111b and the heat insulation board 130 side surface are substantially flush. Further, four protrusions 116 protruding from the outer surface of the bottom wall 111 a of the wiring box 110 bite into the heat insulation board 130 and engage with the heat insulation board 130.

  The screw shaft portion 152 of the screw 150 passes through the fixing hole 113 and the heat insulating board 130 of the wiring box 110 and is screwed (screwed) into the construction surface W1. At this time, the closing piece 115 closes the passage hole 114 (without closing the fixing hole 113) and is located between the screw head 151 and the construction surface W1. In the wiring structure 10, the screw shaft portion 152 is screwed deeply into the construction surface W1, and the screw head portion 151 is in pressure contact with the periphery of the fixing hole 113 (the inner surface of the bottom wall 111a) and the tip portion 115b of the closing piece 115. . That is, when the closing piece 115 is strongly pressed by the screw head 151 in the closing direction, the passage hole 114 is prevented from opening and the screw shaft portion 152 is stably maintained in the fixed hole 113. . Furthermore, since at least one protrusion 116 is engaged with the heat insulation board 130, the wiring box 110 is restricted from rotating with respect to the heat insulation board 130 around the screw 150. Therefore, in the wiring structure 10, the wiring box 110 and the heat insulating board 130 are firmly fixed to the construction surface W <b> 1 with the screws 150. In the present embodiment, the fixing hole 113 is disposed above the passage hole 114, but may be disposed upside down.

  Further, in the present embodiment, a heat insulating layer W2 having a predetermined thickness is filled in the space behind the construction surface W1 and the inner wall W3 and covers the periphery of the wiring device 100. That is, in the wiring structure 10, the heat insulating layer W <b> 2 is almost in close contact with the outer surface of the side wall 111 b of the wiring box 110 and the outer peripheral side surface of the heat insulating board 130, and no significant gap is formed. A part of the heat insulating layer W2 is cut out above the cable insertion portion 122 of the wiring box 110, and a passage for wiring the cable C is formed inside the wiring box 110. In the wiring structure 10, a cable C connected to a power source (not shown) is extended to the back of the wall through the passage.

  A wall hole H is formed in the inner wall W1 in front of the opening 112 of the wiring box 110 (on the wall front side). A pair of appliance mounting holes 121 provided on the opening edge 112a together with the opening 112 of the wiring box 110 face the wall surface through the wall hole H. And the wiring appliance E which is an outlet, a switch, etc. is being fixed to the pair of appliance attachment holes 121 with the screw 121a from the wall surface side. That is, the wiring device E is fixed so as to cover the opening 112 of the wiring box 110 via the pair of device mounting holes 121 of the wiring box 110. Further, the cable C passes through the cable insertion hole 122 formed in the side wall 111 b of the wiring box 110 and is wired inside the wiring box 110. The tip of the cable C is connected to a wiring device E attached to the wiring box 110 via a device mounting hole 121. That is, in the wiring structure 10 of FIG. 7, the wiring device 100 (the wiring box 110 and the heat insulating board 130) is in a state where the heat insulating layer W2 disposed in the wall space effectively insulates the wall surface space and the external space. It is installed behind the wall.

  Next, a method for constructing the wiring structure 10 by installing the wiring box 110 and / or the wiring device 100 will be described with reference to FIGS.

  First, the position where the wiring box 110 is installed in the plane of the construction plane W1 is determined, and the mounting position of the wiring box 110 is written on the construction plane W1. The double-sided adhesive layer 132 exposed on the rear surface of the heat insulation board 130 (with the release sheet removed) is attached to the construction surface W1 while aligning the heat insulation board 130 with the marking lines. Then, with the double-sided adhesive layer 132 temporarily fixed, the screw 150 is driven into the approximate center of the front surface of the heat insulating board 130. The tip of the screw shaft portion 152 of the screw 150 is screwed into the construction surface W1, and the heat insulating board 130 is fixed to the construction surface W1 with the screw 150. At this time, as shown in FIG. 8A, the screw shaft 152 base end is protruded from the front surface of the heat insulation board 130, and the screw head 151 is disposed so as to be separated from the front surface of the heat insulation board 130. The distance between the screw head 151 and the fixed portion is not limited as long as the screw head 151 can be passed through the passage hole 114 and the wiring box bottom wall 111a can be disposed at least between them.

  Next, the wiring box 110 is gripped, and the outer surface of the bottom wall 111a of the wiring box 110 is brought close to the front surface of the heat insulation board 130. At this time, the release sheet is peeled off, and the double-sided adhesive layer 131 on the front surface of the heat insulating board 130 is exposed. Then, the screw head 151 protruding from the heat insulation board 130 is brought into contact with the closing piece 115 (closing the passage hole 114) so as to press the wiring box 110 against the screw 150. As a result, the screw head 151 enters the passage hole 114 and is elastically deformed so that the closing piece 115 rotates toward the inner surface side of the wiring box bottom wall 111a with the base end 115a as an axis (FIG. 8A). reference). When the screw head 151 has completely passed through the passage hole 114, the screw box portion 152 is moved downward from the passage hole 114 to the fixed hole 113 by sliding the wiring box 110 downward. When the screw shaft portion 152 moves into the fixing hole 113, the closing piece 115 and the screw head 151 are separated from each other, and at the same time, the closing piece 115 is elastically restored to close the passage hole 114.

  Next, in a state where the screw shaft portion 152 is inserted into the fixing hole 113, the outer surface of the bottom wall 111a of the wiring box 110 is pressed against the front surface of the heat insulating board 130, and the four protruding portions 116 are digged into the heat insulating board 130. The protrusion 116 is engaged with the heat insulating board 130. Simultaneously with this engagement, the double-sided adhesive layer 131 bonds the outer surface of the wiring box bottom wall 111a and the front surface of the heat insulating board 130 together.

  As shown in FIG. 8B, the wiring box 110 is stably supported and temporarily fixed to the fixed portion (the heat insulating board 130 and / or the construction surface W1) with screws 150. In the support state (attached state) of FIG. 8B, since the closing piece 115 closes the passage hole 114, the relative movement of the screw shaft portion 152 into the passage hole 114 is restricted, and the wiring box 110 is It is prevented that the screw head 151 falls off. Then, the screw 150 is tightened in a state where the wiring box 110 is supported by the fixed portion, and the screw shaft portion 152 is formed on the construction surface W1 until the screw head 151 is pressed against the periphery of the fixing hole 113 and the closing piece tip portion 115b. Screw in. At this time, since the protruding portion 116 of the wiring box 110 is engaged with the heat insulation board 130, the rotation of the wiring box 110 relative to the heat insulation board 130 with the screw 150 being screwed is restricted. Similarly, the double-sided adhesive layer 132 restricts the heat insulating board 130 from rotating with respect to the construction surface W1. That is, in the state of FIG. 8B, the wiring box 110 is stably supported by the fixed portion and the rotation of the wiring box 110 is restricted by the protruding portion 116. The wiring box 110 (wiring device 100) is permanently fixed to the construction surface W1 easily and quickly (without pressing the wiring box 110 with one hand) without worrying about the dropout of the box 110 or the displacement of the position (installation angle). It is possible. As a result, as shown in FIG. 8C, the wiring box 110 is attached to the fixed portion. Although not shown, another screw may be driven into the pair of screw holes 123 of the wiring box 110 to more firmly fix the wiring box 110 to the construction surface W1.

  After the wiring device 100 is installed on the construction surface W1 as shown in FIG. 8C, wiring is performed by providing the heat insulating layer W2 and the inner wall W3. More specifically, as shown in FIG. 9A, the opening 112 of the wiring box 110 is masked with the masking tape M, and the entire wiring device 100 is surrounded (covered) over the construction surface W1. Spray foam insulation material W2 '. As a result, the wiring box 110 and the heat insulating board 130 are embedded in the blowing foam heat insulating material W2 'without a gap. Then, the masking tape M is removed from the opening 112, and a part of the blowing foam heat insulating material W2 'is removed to form a heat insulating layer W2 having a predetermined thickness. Further, in order to route the cable (wiring / piping material) C in the space behind the wall, a part of the heat insulating layer W2 is cut away to provide a wiring path. Note that the blowing foam heat insulating material W <b> 2 ′ may be blown only around the heat insulating board 130. In addition, the cable C is wired before the blowing foam heat insulating material W2 ′ is formed, and after the cable C is accommodated in the protective tube, the blowing foam heat insulating material W2 ′ is sprayed from above the protective tube. The wiring device 100 may be embedded in the heat insulating layer W2.

  Next, as shown in FIG. 9B, the cable C is routed along the wiring path, and the tip is inserted into the cable insertion portion 122 of the wiring box side wall 111b. After wiring the cable C, the inner wall W3 is erected. Although not shown in the figure, the inner wall W3 is constructed via a construction material (for example, a pillar material or a trunk edge material) on the back of the wall. At this time, the inner wall W3 is preferably erected so that the opening edge 112a of the wiring box 110 and the front surface of the heat insulating layer W2 are in contact with the back surface of the inner wall W3.

  Subsequently, the position of the wiring box 110 is detected from the wall surface side, and the wall hole H (for example, oval shape) is formed with a horuseau or the like so that the opening 112 of the wiring box 110 and the pair of appliance mounting holes 121 face the wall surface. To drill. Next, the end of the cable C is pulled out to the front side of the wall and connected to a wiring device E such as an outlet or switch. And the wiring structure 10 can be constructed | assembled by fixing the wiring instrument E to the wiring box 110 with the screw | thread 121a through a pair of instrument attachment hole 121. FIG. In addition, the installation method of the wiring / pipe box described here is only an example, and those skilled in the art can change the order of each process, change or omit unnecessary processes according to the situation, or add It is also possible to add a process.

  Hereinafter, the effect in the wiring apparatus 100 and the wiring box 110 of one Embodiment which concerns on this invention is demonstrated.

  According to the wiring device 100 and the wiring box 110 of the present embodiment, the heat insulation board 130 as a part of the fixed portion and the screw head 151 of the screw 150 screwed into the construction surface W1 in a protruding state are connected to the wiring box 110. The passage hole 114 is elastically deformed and brought into contact with the closing piece 115 to be opened. Then, the screw head 151 is passed through the inside of the box from the passage hole 114 and the screw shaft portion 152 is relatively moved into the fixed hole 113, and the passage hole 114 is closed by the elastically restored closing piece 115, thereby wiring. The box 110 can be easily and quickly attached to the fixed portion. Further, since the closing piece 115 closes the passage hole 114 with the screw shaft 152 passing through the fixing hole 113, the closing piece 115 locks the screw head 151, and the screw head 151 passes through the passage hole. Passing through 114 again is restricted. That is, when the passage hole 114 is closed by the closing piece 115, the wiring box 110 and the heat insulating board 130 are locked to the screw 150 and are prevented from being separated from each other. Thereby, the wiring box 110 can be stably supported with respect to the heat insulation board 130 and the construction surface W1. Further, in this support state, the protrusion 116 protruding from the outer surface of the bottom wall 111a of the wiring box 110 is engaged with the heat insulating board 130, whereby the rotation of the wiring box 110 is restricted. Thereby, the operator can fix the wiring box 110 (wiring device 100) to the construction surface W1 easily and quickly without worrying about the dropping off of the wiring box 110 or the shift of the position (installation angle). It is. Therefore, the wiring device 10 and the wiring box 110 of this embodiment greatly improve the installation ease and work efficiency.

(Example 6)
In the above embodiment, the fixing hole of the present invention is formed slightly larger than the shaft diameter of the screw, but the present invention is not limited to this. As shown in FIG. 17A, the fixing portion of the wiring box 510 includes a long fixing hole 513 extending left and right on the bottom wall 511 a, a passage hole 514 communicating with the fixing hole 513, and the passage hole 514. And a closing piece 515 that closes the door in an openable / closable manner. The fixing hole 513 is formed in such a size that the screw shaft 552 of the screw 550 (not shown) can pass and the screw head 551 cannot pass. That is, in this embodiment, the lateral width s1 of the fixing hole 513 is larger than the screw head diameter d1 and the screw shaft diameter d2 (s1> d1, d2). In addition, the vertical width s2 of the fixing hole 513 is smaller than the screw head diameter d1 and larger than the screw shaft diameter d2 (d2 <s2 <d1). On the other hand, the passage hole 514 and the closing piece 515 have the same shape as in the first embodiment.

  When the screw shaft portion 552 is inserted into the fixed hole 513 and the closing piece 515 closes the passage hole 514, the screw shaft portion 552 can slide in the longitudinal direction in the fixed hole 513. However, the screw head 551 cannot pass through the fixing hole 513. Therefore, in this embodiment, the wiring box 510 is supported by the screws 550 on the fixed portion (for example, a heat insulating layer, a construction surface, a construction material, etc.) to prevent the wiring box 510 from falling off, and along the longitudinal direction of the fixing hole 513. The mounting position of 510 can be freely adjusted to the left and right. Thereby, the installation work of the wiring box 510 is improved.

  In the wiring box 610 shown in FIG. 17B, the fixing hole 613 extends in the vertical direction, unlike FIG. 17A. The fixing hole 613 is formed in such a size that a screw shaft portion 652 of a screw 650 (not shown) can pass and a screw head portion 651 cannot pass. That is, in this embodiment, the vertical width s2 of the fixing hole 613 is larger than the screw head diameter d1 and the screw shaft diameter d2 (s2> d1, d2). Further, the lateral width s2 of the fixing hole 613 is smaller than the screw head diameter d1, and larger than the screw shaft diameter d2 (d2 <s1 <d1). In other words, in this embodiment, the wiring box 610 is supported by a fixed portion (for example, a heat insulating layer, a construction surface, a construction material, etc.) with screws 650 along the longitudinal direction of the fixing hole 613 while supporting the dropout prevention. The mounting position of 610 can be freely adjusted up and down. Therefore, this embodiment also exhibits the same operational effects as the embodiment of FIG.
