Although not shown, in the present protective duct device and / or protective duct installation structure 10, the base 111, the lid 117 (protective duct 110), and / or the installation pedestal 120 can be selected according to the length of the wiring / piping material. The numbers may be arbitrarily changed, and they may be arranged in the longitudinal direction.

  As shown in FIG. 10A, the pair of engaging claws 119 are respectively formed in the pair of engaging grooves 115 from the outer surface side of the side wall 113 in a state where the closing portion 118 of the lid body 117 closes the opening portion 114 of the base 111. Is engaged. In addition, the outer surface of the curved portion 113b at the tip of the side wall 113 is disposed so as to abut along the inner surfaces of both ends of the lid body 117. FIG. 10A is a cross-sectional view of the vicinity of the end in the longitudinal direction of the lid 117. Here, the cover 126 of the installation base 120 is disposed outside the closing portion 118 of the lid 117. . That is, both end portions in the width direction of the lid body 117 enter the inside from the longitudinal cutouts of the flange portions 121 b of the base body 121. At this time, the contact surface 126a of the cover 126 and the end surface of the lid 117 are in contact. That is, in the longitudinal direction of the base 111, the installation base 120 and the lid body 117 partially overlap with each other via the cover portion 126. As a result, the end portion in the longitudinal direction of the lid body 117 disposed adjacent to both sides of the mounting base 120 is covered with the covering portion 126 without exposing a gap between the mounting base 120 and the lid body 117.

  As illustrated in FIG. 10B, the installation base 120 is installed between the pair of side walls 113 of the protective duct 110. At this time, the frame part 121a of the installation base 120 is stretched over the opening part 114 so that the bottom wall 112 faces the front surface from the opening part 122a and the opening part 114, and the flange part 121b of the installation base 120 is the base. The outer surface of the curved part 113b of the side wall 113 of 111 is covered from the side. Then, the engaging convex portion 123 is fitted into the engaging groove 115 from the outer surface of the side wall 113. That is, the mounting base 120 is fitted to the base 111 of the protective duct 110 by the engagement (fitting) between the engagement convex portion 123 and the engagement groove 115.

  As shown in FIG. 10C, the pair of restricting portions 124 of the mounting base 120 extend substantially perpendicular to the wall surface W so as to face the inner surface of the side wall 113 in the wiring / pipe space inside the base 111. More specifically, the contact piece 124 a of the restricting portion 124 extends linearly from the opening 122 a of the instrument mounting portion 122 to the bottom wall 112 of the base 111. Further, the restricting portion 124 is disposed at a position shifted from the engaging convex portion 123 in the longitudinal direction of the protective duct 110. And the side wall 113 is arrange | positioned between the engagement convex part 123 and the contact piece 124a by the positional relationship of the width direction of the protective duct 110. FIG. In other words, when the side wall 113 of the base 111 is bent and deformed toward the inner surface side in the width direction, the restricting portion 124 is opposite to the engaging convex portion 123 with the side wall 113 interposed therebetween so as to support the side wall 113 from the inner surface (the other surface). Extends to the side. Each contact piece 124a is separated from the inner surface of each side wall 113 or a part thereof (the tip of the curved portion 113b or the tip of the rib 116) by a predetermined distance. The separation distance is smaller than the insertion depth of the engagement protrusion 123 into the engagement groove 115. Similarly, this separation distance is preferably smaller than the insertion depth of the engaging claw 119 of the lid 117. Further, the rear surface of the refractive piece 124b is in contact with the bottom wall 112 by the surface. The protective duct 110 is fixed to the wall surface W by the screw 125a passing through the bottom wall 112 through the fixing hole 125 formed in the refracting piece 124b. That is, the screw 125a directly fixes both the protective duct 110 and the mounting base 120 to the wall surface W. Therefore, in the protective duct installation structure 10, the instrument installation device 100 is installed on the wall surface W in a state where the installation base 120 is firmly fixed to the protective duct 110.

  FIG. 11 is a partially enlarged sectional view of FIG. 10C in a state where the protective duct 110 is bent and deformed. In the bending deformation state of FIG. 11, force is applied to the side wall 113 of the protective duct 110 from the outer surface in the width direction, and the side wall 113 is tilted to the inner surface side. And the front-end | tip of the curved part 113b which is a part of inner surface of the side wall 113 is latched by contacting the contact piece 124a outer surface of the control part 124. At this time, since the restricting portion 124 is fixed to the bottom wall 112 and the wall surface W, the restricting portion 124 can stably restrict the tilt of the side wall 113 even if the side wall 113 is tilted by a strong force. Further, in the bending deformation state of FIG. 11, as the side wall 113 is tilted, the engagement convex portion 123 shifts to the outer surface side with respect to the engagement groove 115 and the tip thereof moves to the vicinity of the opening of the engagement groove 115. ing. However, as shown in FIG. 10C, in a normal state where no bending deformation occurs, the distance between the restricting portion 124 and the inner surface of the side wall 113 is that the engaging protrusion 123 and the engaging claw 119 are inserted into the engaging groove 115. Therefore, the engagement convex portion 123 and the engagement claw 119 are restricted from being detached from the engagement groove 115 at the time of bending deformation. That is, in the protection duct installation structure 10, the installation base 120 and the lid body 117 are firmly attached to the protection duct base 111.

  Next, the process of constructing the protective duct installation structure 10 will be described. First, the place where the wiring / pipe material is arranged on the wall surface W is determined, and the position where the protective duct 110 is fixed and the position where the instrument W is installed are determined on the wall surface W. Then, the engagement convex portion 123 of the installation base 120 is engaged with the engagement groove 115 of the protection duct 110, and the installation base 120 is attached to the base 111 of the protection duct 110. At this time, the installation base 120 may be fitted to the base 111 while pushing the installation base 120 from the front of the base 111 to bend and deform the flange portion 121b outward. Alternatively, the installation base 120 may be fitted to the base 111 so that the installation base 121 is slid laterally from the end of the base 111 in the longitudinal direction. Since the restricting portion 124 is disposed at a position shifted from the engaging convex portion 123 in the longitudinal direction of the protective duct 110, either the engaging convex portion 123 or the restricting portion 124 is used as the side wall of the base 111. After being arranged with respect to 113, the other can be arranged with respect to the side wall 113 at a different position in the longitudinal direction of the base 111. Thereby, it can suppress that the engagement convex part 123 and the control part 124 interfere with each other, and can engage the engagement convex part 123 with the engagement groove | channel 115 easily.

  Then, with the mounting base 120 fitted to the protective duct 110, the bottom wall 112 of the base 111 is directed to a predetermined position on the wall surface W, and the screw 125a is screwed into the fixing hole 125 from the opening 122a. The base 111 is fixed to the wall surface W together with 120. Subsequently, the wiring / piping material is arranged in the wiring / piping space inside the base 111, the wiring / piping material is connected to the instrument K, and the instrument K is fixed to the instrument mounting portion 122 of the installation base 120 with screws. To do. Next, the lid 117 is pressed against the base 111 from the front so as to close the opening 114 with the lid 117, and the lid 117 is fitted to the base 111 on both sides of the installation base 120. Subsequently, the lid 117 is slid in the longitudinal direction of the base 111, and the end of the lid 117 is disposed in the cover 126. The protective duct installation structure 10 can be constructed through the above steps.

  However, it is possible to change the order of each process or to omit unnecessary processes as appropriate, and the process of constructing the protective duct installation structure 10 is not limited to the above process. For example, you may install the instrument installation apparatus 100 in the wall surface W as follows. First, the base 111 of the protective duct 110 is fixed to a predetermined position on the wall surface W (without the fixing hole 125), and then the wiring / pipe material is disposed in the wiring / pipe space. Then, the two lids 117 are assembled to the base 111 so that the ends of the two lids 117 are spaced in the longitudinal direction of the base 111. Next, the mounting base 120 is assembled to the base 111 so that the engagement protrusion 123 is fitted into the engagement groove 115 of the base 111 exposed between the two lids 117. Subsequently, the screw 125 a is screwed into the fixing hole 125, and the restricting portion 124 of the mounting base 120 is fixed to the bottom wall 112 and the wall surface W of the protective duct 110. Finally, the wiring / piping material is connected to the appliance K, and the appliance K is attached to the appliance mounting portion 122 of the installation base 120.

  Hereinafter, the effect in the instrument installation apparatus (protection duct apparatus) 100 of one Embodiment which concerns on this invention is demonstrated.

  According to the instrument installation device 100 of the present embodiment, the engagement convex portion 123 enters the engagement groove 115 from the outer surface (one surface) side of the side wall 113 of the base 111 with the installation base 120 attached to the protective duct 110. And the contact piece 124a of the restricting portion 124 is arranged to extend on the inner surface (the other surface) side of the side wall 113. Then, when the side wall 113 of the base 111 is bent and deformed toward the inner surface side in the width direction, the contact piece 124 a contacts the inner surface of the side wall 113 and restricts the tilt of the side wall 123. Furthermore, since the separation distance between the restricting portion 124 and the inner surface of the side wall 113 is smaller than the insertion depth of the engaging convex portion 123 and the engaging claw 119 with respect to the engaging groove 115, the engaging convex portion 123 and the engaging claw at the time of bending deformation. The disengagement of the 119 from the engagement groove 115 is restricted. As a result, the engagement protrusion 123 and the engagement claw 119 are prevented from being detached from the engagement groove 115 and the installation base 120 and the lid body 117 are prevented from being detached from the base 111 of the protective duct 110. Therefore, the instrument installation apparatus 100 according to the present embodiment can more stably maintain the configuration in which the installation base 120 and the lid 117 are attached to the protective duct base 111.

  Further, in the conventional arrangement device (equipment installation device), since the protruding piece (14) extends along the longitudinal direction on the bottom surface of the wiring duct (11), the wiring device is not particularly disposed. In this case, the projecting piece (14) obstructs the wiring and piping space. On the other hand, when the protruding piece (14) is removed in order to expand the wiring / piping space of the wiring duct (11), only the engagement between the protruding piece (31) and the concave strip (13) is required to attach the wiring device. The frame (23) is more easily detached from the wiring duct (11). In the present embodiment, since the restricting portion 124 assists in maintaining the engagement between the engaging convex portion 123 and the engaging groove 115, the protective duct 110 is not necessarily fixed to the wall surface W together with the protective duct 110. And the mounting base 120 can be stably maintained. That is, in this embodiment, by strengthening the coupling between the engaging portion and the engaged portion, the projecting piece (14) of the conventional arrangement device can be omitted, and the wiring / pipe space is further reduced. It can also be used widely. Furthermore, in the present embodiment, a fixing hole 125 is provided in each regulating portion 124 of the installation base 120. For this reason, wiring / pipe space is not narrowed over the whole longitudinal direction unlike the past. That is, the instrument installation apparatus 100 of the present embodiment further enhances the fixing of the protective duct 110 and the installation base 120 to the wall surface without narrowing the wiring / piping space more than necessary.

  The present invention is not limited to the above embodiment, and various embodiments and modifications can be taken. Hereinafter, a second embodiment and a modification of the present invention will be described. In each embodiment, components having the same last two digits have the same or similar features, and a part of the description is omitted.

[Second Embodiment]
With reference to FIG.12 and FIG.13, the protection duct apparatus 200 and the construction body 220 of 2nd Embodiment are demonstrated. In addition, the protective duct 210 of this embodiment is the same as the protective duct 110 of 1st Embodiment, and is provided with the base 211 and the cover body 217. 12A, 12B, and 12C are a schematic perspective view, a rear view, and a side view of the instrument installation device 200 according to an embodiment of the present invention. FIG. 13 is a schematic cross-sectional view of the protective duct device. And although the protection duct apparatus of this invention is a concept containing an instrument installation apparatus, it does not need to have the function to install an instrument like 1st Embodiment. Similarly, the erected body of the present invention is a concept including an installation base, but its application is not limited to “application for installing an instrument”.

  As shown in FIG. 12, the erected body 220 of this embodiment has a function as a lid that closes the opening 214 of the protective duct 210. The erected body 220 is represented as a plate having a rectangular shape in front view, but may be a long body that is continuous in the longitudinal direction. The installation body 220 includes a main body 221, an engagement convex portion 223 as an engagement portion that engages with an engagement groove 215 of the base 211 from the outer surface (one surface) side of each side wall 213, and the base 211. A regulating portion 224 for regulating the deformation of the side wall 213 in the width direction, and a cover portion 226 for covering the end portion of the lid 217 disposed adjacent to the construction body 220.

  The main body portion 221 functions as a closing portion for closing the opening portion 214 of the protective duct 210. The main body 221 is greatly bent from the front side to the back side at both ends in the width direction, and a plurality of (two in the present embodiment) pairs of engaging convex portions 223 face each other inward in the width direction. It extends like so. The width of the interval (or the main body 221) between the pair of opposing engaging projections 223 corresponds to the width of the opening 214 of the protective duct 210. Further, the engaging convex portions 223 adjacent to each other in the longitudinal direction (left and right direction in FIG. 12B) are arranged at positions spaced equidistant from the center. Each engaging convex portion 221 extends along the longitudinal direction of the protective duct 210 and is configured to be fitted into the engaging groove 215 of the protective duct 210 when the erected body 220 is attached to the protective duct 210. ing.

  The restricting portion 224 linearly extends from the back surface of the main body portion 221 to the back side inside the width direction (vertical direction in FIG. 12B) of each engagement convex portion 223. The restricting portion 224 includes a contact piece 224a having an elongated flat plate shape extending substantially perpendicularly to the back side. The contact piece 224 a is shorter than the height of the side wall 213 of the base 211. Further, each restricting portion 224 is disposed at a substantially center in the longitudinal direction. That is, each restricting portion 224 is disposed at a position different from the engaging convex portion 223 in the longitudinal direction of the protective duct 210 (the left-right direction in FIG. 12B).

  Formed on both ends (or one end) of the main body 221 in the longitudinal direction so that the cover 226 can cover the end of the lid 217 arranged adjacent to the installation body 220 in the longitudinal direction of the base 211. Has been. In other words, the cross-sectional shape of the cover 226 is slightly larger than the cross-sectional shape of the cover 217 so that the bent inner surface of the cover 226 contacts the outer surface of the cover 217. Accordingly, the erected body 220 and the lid body 217 can be arranged so as to overlap with each other in the longitudinal direction of the base 211 via the cover portion 226. The cover 226 can connect the short lid 217 to the long base 211 in the longitudinal direction and suppress the lids 217 from coming off the base 211.

  In the protective duct device 200 of this embodiment shown in FIG. 13, the erected body 220 is erected in the width direction of the opening 214 of the protective duct 210. At this time, both ends in the width direction of the erected body 220 cover the outer surface of the curved portion 213b of the side wall 213 of the base 211, respectively, and the engaging convex portion 223 is fitted into the engaging groove 215 from the outer surface of the side wall 213. Yes. That is, the erected body 220 is attached to the protective duct 210 by engagement (fitting) between the engagement convex portion 223 and the engagement groove 215. And the control part 224 of the construction body 220 is extended so that the side wall 213 inner surface which adjoins in the internal space of the base 211 may be opposed. Further, the restricting portion 224 is disposed at a position shifted from the engaging convex portion 223 in the longitudinal direction of the protective duct 210. And the side wall 213 is arrange | positioned between the engagement convex part 223 and the contact piece 224a by the positional relationship of the width direction of the protection duct 210. FIG. In other words, when the side wall 213 of the base 211 is bent and deformed toward the inner surface side in the width direction, the restricting portion 224 is opposite to the engaging convex portion 223 with the side wall 213 interposed therebetween so as to support the side wall 213 from the inner surface (the other surface). Extends to the side. Each contact piece 224a is separated from the inner surface of each side wall 213 or a part thereof (the tip of the curved portion 213b or the tip of the rib 216) by a predetermined distance. The separation distance is smaller than the insertion depth of the engagement protrusion 223 into the engagement groove 215. Thus, when the protective duct 210 is bent and deformed, the restriction portion 224 restricts the tilting of the side wall 213 and restricts the engagement convex portion 223 from being disengaged from the engagement groove 215. Therefore, the protection duct device 200 of the present embodiment enables the installation body 220 to be attached to the protection duct 210 more stably.

  Therefore, the protective duct device 200 and the erected body 220 of the present embodiment can similarly exhibit the effect of the present invention that can suppress the bending of the protective duct.
