Then, a rib-like protrusion 4f that protrudes inward is provided at the tip of the connection port 4a, and the protrusion 4f is brought into contact with the outer peripheral surface of the protection duct 3 so that the protection duct 3 is attached. To support. Therefore, a space is provided between the protective ducts 3 on the back side of the projection 4f of the connection port 4a, and the escape space 4c is formed by this space.

  Further, the projecting piece 4x is a flat plate extending in the extending direction P of the connection port 4a and having a plate surface facing a direction orthogonal to the extending direction P. In the illustrated embodiment, the plate surface has a rectangular shape in which the direction protruding from the inner peripheral surface of the connection port 4a is longer than the extending direction P (see FIG. 8). The protruding pieces 4x and 4x are arranged so that the protruding pieces 4x and 4x are aligned in the extending direction P of the connection port 4a. Specifically, the protruding pieces 4x are provided at left and right positions on the top plate 4e of the connection port 4a, that is, two sets are provided, and in each set, they are arranged in a line in the extending direction P of the connection port 4a. Are arranged as follows.

  On the other hand, the other connection port 4d is configured such that a sheath tube 5 (specifically, a corrugated sheath tube) that protects the wiring / piping material 2 is fitted, and thus the other connection port 4d has the sheath tube 5 attached thereto. By fitting, the other connection port 4d and the sheath tube 5 are connected to each other. The other connection port 4d has a plurality of types (in detail, four types) of connection ports having different inner diameters so as to correspond to a plurality of types (specifically, four types) of the sheath tubes 5, 5 having different outer diameters. 4g, 4g. Each connection port 4g is formed in a U-shaped cross section so that the construction surface 1 side is open. And these connection port parts 4g and 4g are located in a line so that a diameter may become small as the connection port part 4g located in the front end side. Here, the adjacent connection port portions 4g and 4g are formed to be severable. In the illustrated embodiment, the other connection ports 4d are formed so that the connection port portions 4g and 4g can be easily disconnected. For example, V-shaped notches 4h and 4h are provided on the outer peripheral surface of the.

  Therefore, the connection port 4g is used as a connection port connected to the sheath tube 5 by cutting away the tip side from the connection port portion 4g corresponding to the sheath tube 5 that is actually connected. However, in FIGS. 1-3, since the most advanced connection port part 4g is used, neither connection port part 4g is cut off. Moreover, in each connection port part 4g, the engaging part 4i engaged with the groove | channel 5a of the sheath pipe 5 is provided in the front end side so that it may protrude from an inner peripheral surface, and the outer peripheral surface of the sheath pipe 5 is provided in the back side. A support portion 4j that supports the sheath tube 5 by contacting is provided. In the illustrated embodiment, the support portion 4j is formed of a rib protruding from the inner peripheral surface of the connection port portion 4g, and this rib extends from the engagement portion 4i toward the back in each connection port portion 4g. Is done. In the illustrated embodiment, a bushing 6 that fills the space between the sheath tube 5 and the wiring / piping material 2 is attached to the end of the sheath tube 5.

  The attached protective cover 4 is provided with a fixing portion 4k for fixing the attached protective cover 4 to the construction surface 1. The fixing portion 4k is formed in a hook shape so as to project laterally, and a fixing hole 4m is formed in the fixing portion 4k. Therefore, the attached protective cover 4 is attached and fixed to the construction surface 1 by a fixing tool 7 such as a screw or a nail that is screwed or driven into the construction surface 1 through the fixing hole 4m.

  Next, the effect of the attached protective cover 4 having the above configuration will be described. According to the accessory protection cover 4, the protection duct 3 is fitted into the connection port 4 a of the accessory protection cover 4, so that the protection duct 3 and the accessory protection cover 4 are connected to each other. At this time, the connecting port 4a is provided with a restricting portion 4b facing the end surface 3d of the protective duct 3, and the restricting portion 4b restricts the amount of the protective duct 3 entering the depth of the connecting port 4a. Thereby, the displacement of the protective duct 3 is prevented. Here, a plurality of restricting portions 4b are formed so as to correspond to a plurality of amounts of entry of the protective duct 3 into the connection port 4a, and at least the restricting portions 4b excluding the innermost restricting portion 4b can be broken off. It consists of a protruding piece 4x. Accordingly, the restriction portion 4b positioned on the base side of the connection port 4a, that is, the protruding piece 4x is broken away from the restriction portion 4b corresponding to the entry amount of the protective duct 3 into the connection port 4a. The restricting portion 4b that faces the end surface 3d of the protective duct 3 prevents the protective duct 3 from entering the back of the connection port 4a (in FIG. 2, one protrusion located on the mouth side of the connection port 4a). The piece 4x is broken off, and the protruding piece 4x in the back prevents the protective duct 3 from entering.) Thereby, the difference in the length of the protective duct 3 can be absorbed by the restricting portion 4b formed of the projecting piece 4x that can be broken off, and therefore it is not necessary to cut the protective duct 3 accurately. And since it is not necessary to cut | disconnect the protective duct 3 correctly in this way, the connection operation | work of the attached protective cover 4 and the protective duct 3 can be performed easily. Of course, when the restricting portion 4b corresponding to the amount of entry of the protective duct 3 into the connection port 4a is the restricting portion 4b located at the forefront, none of the restricting portions 4b is broken off. .

  Moreover, since the protrusion 4x which forms the control part 4b consists of flat plates, this protrusion 4x can be easily folded. In addition, since the projecting piece 4x extends in the extending direction P of the connection port 4a, the strength in the depth direction, which is the extending direction P, is increased, and it is possible to accurately prevent excessive entry of the protective duct 3. it can.

  The connection port 4a is provided with a relief space 4c for the projecting piece 4x. By providing the escape space 4c in this way, the protrusion 4x may be folded without being removed from the connection port 4a when connecting to the protective duct 3. Therefore, as shown in FIG. 1, when the accessory protective cover 4 is pressed against the protective duct 3 and assembled, the amount of entry of the protective duct 3 into the connection port 4a (the amount of downward entry in FIGS. 1 and 2). ), The restricting portion 4b located on the base side of the connection port 4a, that is, the protruding piece 4x, is pushed and folded by the protective duct 3, but the protruding piece 4x is left as it is as a relief space. 4c. However, the protruding piece 4x is folded without being removed from the inner peripheral surface of the connection port 4a and stays in the escape space 4c. In addition, the projecting piece 4x is folded and removed from the inner peripheral surface of the connection port 4a. , It may remain in the escape space 4c.

  Further, as described above, the attached protective cover 4 is connected to one end of the protective duct 3, but in addition, when another attached protective cover is connected to the other end of the protective duct 3. It is preferable that the pitch between the restricting portions 4b and 4b in the auxiliary protective cover 4 is smaller than the reference amount of the protective duct 3 to the connection port of the other auxiliary protective cover. By doing so, even if the protective duct 3 is displaced toward the attached protective cover 4 side, the displacement is suppressed within the pitch between the restricting portions 4b and 4b. For this reason, the protective duct 3 does not come off from the connection port of the other accessory cover.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the wiring / piping material 2 may be a power line, a signal line, an optical fiber or the like as the wiring material, and may be a water pipe, a drain pipe, a refrigerant pipe, a gas pipe or the like as the piping material.

  In addition, the attached protective cover 4 is composed of a base on the construction surface 1 side and a cover to be assembled to the base, even if it does not consist of a cover body that opens on the construction surface 1 side. The piping material 2 may be accommodated.

  Further, the attached protective cover 4 may not be formed in a straight shape, but may be formed by bending (bending on a plane, bending on a protruding corner, or bending on an entering corner). The wiring / pipe material 2 along 1 may be guided below the construction surface 1.

  Further, even though the restricting portion 4b provided in the connection port 4a is not entirely formed of the projecting piece 4x that can be broken, the innermost restricting portion 4b may be formed so as not to be broken.

  Even if the restricting portion 4b is not arranged so as to be aligned in the extending direction P of the connection port 4a, the restricting portion 4b may be arranged so as to be shifted in the circumferential direction. Thereby, the pitch between the regulation parts 4b and 4b can be made small.
