It may have a fixing portion for fixing the attachment portion to the wall.

Regarding the separating member, the main body may have a short shape shorter than the dimension along the longitudinal axis of the duct.
Regarding the separating member, the duct may be attached to the attachment portion via double-sided tape, and the attachment portion may have an attachment surface to which the double-sided tape is attached.

Regarding the separating member, the separating member has a plurality of legs that come into contact with the wall surface in a fixed state with respect to the wall, and the plurality of legs may be separated from each other.
Regarding the separating member, the fixing portions are provided on both sides of the attachment portion in between, and the attachment portion and both of the fixing portions are aligned along the reference line, and the dimensions of the main body along the reference line. May be less than or equal to the width of the duct.

In the wiring / piping material laying structure for solving the above problems, a separating member made of a material that transmits ultraviolet rays is fixed to the wall surface of the indoor wall of the building, and the wiring / piping material laying route is provided to the separating member. A long duct may be attached to the inside, and the wiring / piping material may be laid in the laying path of the duct.

(First Embodiment)
Hereinafter, a first embodiment embodying a separation member, a wiring / piping material laying structure, and a duct installation device will be described with reference to FIGS. 1 to 10.

As shown in FIG. 1, a long duct 10 made of a synthetic resin material is laid on the wall surface Wa of the indoor wall W as a wall of a building via a plurality of separating members 20. The duct 10 is laid on the indoor wall W so that the longitudinal axis extends in the vertical direction.

The duct 10 is configured by integrating a long gutter-shaped duct main body 11 and a long lid 15. The duct main body 11 has a long plate-shaped bottom wall 12 and two side walls 13 that rise at intervals from the inner surface 12a of the bottom wall 12. The two side walls 13 face each other with a gap in the width direction of the bottom wall 12. Further, each side wall 13 extends along the long edge portion of the bottom wall 12 over the entire longitudinal axis of the bottom wall 12.

The duct main body 11 has a U-shaped cross section in the width direction. The duct body 11 has a storage space 14 defined by a bottom wall 12 and two side walls 13. The duct body 11 opens from between the two side walls 13. Each of the two side walls 13 has a shape that bends so as to protrude outward. The duct main body 11 is attached to the separating member 20 by attaching the outer surface 12b of the bottom wall 12 to the separating member 20.

The lid 15 has a long plate-shaped top plate 16 and two standing walls 17 that rise from the inner surface 16a of the top plate 16 at intervals. The two standing walls 17 face each other with a gap in the width direction of the top plate 16. Further, each standing wall 17 extends along the long edge portion of the top plate 16 over the entire longitudinal axis of the top plate 16. The lid body 15 has a U-shaped cross section in the width direction. The lid 15 opens from between the two standing walls 17. Each of the two standing walls 17 has a shape that bends so as to protrude outward.

Each vertical wall 17 of the lid 15 is fitted to the outside of each side wall 13 of the duct main body 11. The accommodation space 14 of the duct main body 11 is closed over the entire longitudinal axis by the top plate 16 of the lid body 15. A laying path 18 is defined inside the duct 10. The laying path 18 is defined by the bottom wall 12 and the side wall 13 of the duct main body 11, and the top plate 16 and the vertical wall 17 of the lid 15. The laying path 18 is defined over the entire longitudinal axis of the duct 10.

An optical cable 19 as a wiring / piping material is laid in the laying path 18 of the duct 10. Examples of wiring / piping materials include coaxial cables, communication cables, and synthetic resin flexible conduits.

The duct 10 includes a wide duct 101 and a narrow duct 102 having relatively different widths.
As shown in FIG. 7 or 10, in the wide duct 101, the dimension of the bottom wall 12 in the width direction is defined as the width W1, and in the narrow duct 102, the dimension of the bottom wall 12 in the width direction is defined as the width W2. The width W1 of the wide duct 101 is wider than the width W2 of the narrow duct 102.

As shown in FIG. 2 or 3, the separating member 20 includes a square plate-shaped main body 21 and a double-sided tape 41 attached to the main body 21. The main body 21 has an attachment portion 22 to which the duct 10 is attached, and a fixing portion 31 for fixing the attachment portion 22 to the indoor wall W. The main body 21 has a short shape shorter than the dimension along the longitudinal axis of the duct 10.

Specifically, the main body 21 has a long square plate-shaped attachment portion 22 and rectangular block-shaped fixing portions 31 provided on both sides of the attachment portion 22. The attachment portion 22 and both fixing portions 31 are integrally molded. The attachment portion 22 and both fixing portions 31 are made of a synthetic resin material that is colorless and transparent and can transmit ultraviolet rays. Examples of such synthetic resin materials include polycarbonate and acrylic.

The dimension of the mounting portion 22 in the plate thickness direction Z is defined as the thickness. The attachment portion 22 and both fixing portions 31 are arranged along the reference line L. The extending direction of the reference line L is the wide direction X of the main body 21. Looking at the main body 21 in the plate thickness direction Z is defined as the front view of the main body 21. In the front view of the main body 21, the main body 21 has a long square shape. Further, the direction orthogonal to both the wide direction X and the plate thickness direction Z is defined as the narrow direction Y of the main body 21. Therefore, when the main body 21 is viewed from the front in the plate thickness direction Z, the long side of the main body 21 extends in the wide direction X, and the short side of the main body 21 extends in the narrow direction Y.

The dimension L1 of the main body 21 in the wide direction X is the same as the width W1 of the wide duct 101. That is, the dimensions of the main body 21 along the reference line L are the same as those of the wide duct 101. The dimension L2 of the main body 21 in the narrow direction Y is the same as the width W2 of the narrow duct 102.

The attachment portion 22 includes a attachment surface 22a on one surface in the plate thickness direction Z. In the front view of the main body 21, the sticking surface 22a has a rectangular shape. Further, the sticking surface 22a is a flat surface. One side of the double-sided tape 41 is attached to the attachment surface 22a.

The dimension of the fixing portion 31 in the plate thickness direction Z is defined as the thickness. The thickness of each fixing portion 31 is thicker than the thickness of the mounting portion 22. Each of the two fixing portions 31 is provided with two insertion holes 32. Therefore, the main body 21 is provided with four insertion holes 32. Each of the four insertion holes 32 opens in the first end surface 31a and the second end surface 31b in the plate thickness direction Z. The first end surface 31a of the fixing portion 31 is a surface aligned with the attachment surface 22a of the attachment portion 22 in the front view of the main body 21. Each insertion hole 32 is opened at the first end surface 31a and the second end surface 31b so as to extend in the narrow direction Y.

As shown in FIG. 4 or 5, the dimension of each insertion hole 32 in the narrow direction Y gradually decreases from the first end surface 31a toward the center of the plate thickness direction Z of the fixing portion 31, and the second end surface. It gradually decreases from 31b toward the center of the fixing portion 31 in the plate thickness direction Z. Therefore, the inner surface that defines each insertion hole 32 and faces the narrow direction Y is inclined from the first end surface 31a toward the center of the fixing portion 31, and the plate thickness of the fixing portion 31 is from the second end surface 31b. Inclin towards the center of direction Z.

A fixing nail 50 for fixing the separating member 20 to the indoor wall W is inserted into each insertion hole 32. The fixing nail 50 has a head portion 50a and a shaft portion 50b integrated with the head portion 50a. The length of the shaft portion 50b is sufficiently longer than the thickness of the fixed portion 31.

Each fixing portion 31 is provided with a head recess 31c around the insertion hole 32 of the first end surface 31a. The head recess 31c is slightly recessed from the first end surface 31a toward the insertion hole 32. The head recess 31c has an elongated hole shape surrounding the insertion hole 32. The width of the head recess 31c in the wide direction X is slightly larger than the diameter of the head 50a.

As shown in FIG. 2, the first end surface 31a of each fixing portion 31 is located at a position protruding from the attachment surface 22a of the attachment portion 22 in the plate thickness direction Z. The sticking surface 22a is recessed in the plate thickness direction Z from the two first end surfaces 31a. The dimension from the sticking surface 22a to the first end surface 31a in the plate thickness direction Z is smaller than the thickness of the double-sided tape 41. Therefore, when one adhesive surface 41a of the double-sided tape 41 is attached to the attachment surface 22a, the other adhesive surface 41a of the double-sided tape 41 protrudes from the first end surface 31a. It can be said that the attachment portion 22 is composed of an attachment surface 22a to which the double-sided tape 41 is attached.

The separating member 20 is composed of a main body 21 and a double-sided tape 41 attached to the attachment surface 22a of the attachment portion 22 of the main body 21.
Then, the duct installation device 60 is composed of the wide duct 101, the narrow duct 102, and the separating member 20. In the duct installation device 60, the wide duct 101 and the narrow duct 102 have a long shape that internally defines the laying path 18 of the optical cable 19, and the widths are relatively different. Further, in the duct installation device 60, the separation member 20 includes a main body 21 that is interposed between the indoor wall W and the wide duct 101 or the narrow duct 102 to separate the optical cable 19 from the wall surface Wa, and the main body 21 is provided. Is made of a material that transmits ultraviolet rays. The main body 21 has an attachment portion 22 to which the wide duct 101 or the narrow duct 102 is attached. The shape of the attachment portion 22 when viewed from the front of the separating member 20 is a rectangular shape having the same width as the wide duct 101 as the long side and the same width as the narrow duct 102 as the short side.

The laying structure of the duct 10 using the separating member 20 will be described.
First, the laying structure of the wide duct 101 will be described.
As shown in FIG. 1, a wide duct 101 is laid on the wall surface Wa of the indoor wall W via a plurality of separating members 20. The front view is to see the indoor wall W along the direction orthogonal to the wall surface Wa. In the front view of the indoor wall W, the plurality of separating members 20 are fixed to the indoor wall W so that the wide direction X is the horizontal direction and the narrow direction Y is the vertical direction.

As shown in FIG. 6, each separating member 20 is fixed to the indoor wall W by driving a fixing nail 50 inserted into each insertion hole 32 into the indoor wall W. The fixing nails 50 are inserted one by one into the insertion holes 32.

Of the two insertion holes 32 arranged in the vertical direction, the fixing nail 50 inserted through the upper insertion hole 32 has a shaft portion 50b projecting diagonally upward from the first end surface 31a toward the second end surface 31b. It is inserted through the insertion hole 32. Of the two insertion holes 32 arranged in the vertical direction, the fixing nail 50 inserted through the lower insertion hole 32 has a shaft portion 50b projecting diagonally downward from the first end surface 31a toward the second end surface 31b. It is inserted into the insertion hole 32. Each fixing nail 50 is guided so as to be inclined obliquely by the inclined surface of the insertion hole 32. At this time, the fixing nail 50 is inserted into the insertion hole 32 so that the distance between the shaft portions 50b adjacent to each other in the narrow direction Y increases as the tip of the fixing nail 50 moves away from the second end surface 31b of the fixing portion 31. ing. A part of each head 50a is housed in the head recess 31c.

As shown in FIG. 1, the plurality of separating members 20 are fixed to the indoor wall W at intervals in the vertical direction. A wide duct 101 is attached to these plurality of separating members 20. The wide duct 101 is laid so that the longitudinal axis extends in the vertical direction. In the wide duct 101, the outer surface 12b of the bottom wall 12 of the duct main body 11 is attached to the double-sided tape 41 of each separating member 20. The wide duct 101 is attached to the separating member 20 by the double-sided tape 41.

As shown in FIG. 7, the outer surface 12b of the bottom wall 12 of the wide duct 101 is separated from the wall surface Wa of the indoor wall W by the thickness of the separating member 20. Therefore, in the outer surface 12b of the bottom wall 12 of the wide duct 101, a gap S corresponding to the thickness of the separating member 20 is formed between the portion of the outer surface 12b that is not opposed to the separating member 20 and the wall surface Wa of the indoor wall W. exist. The thickness of the separating member 20 is the sum of the thickness of the fixing portion 31 in the main body 21 and the thickness of the double-sided tape 41 protruding from the first end surface 31a.

The width W1 of the wide duct 101 is the same as the dimension L1 of the main body 21. Therefore, when both end faces in the width direction of the wide duct 101 and both end faces in the wide direction X of the main body 21 are aligned with each other in the front view of the indoor wall W and the wide duct 101 is attached to the separating member 20, two The fixing portion 31 is hidden behind the wide duct 101. That is, the insertion hole 32 of the fixing portion 31 and the head portion 50a of the fixing nail 50 are covered with the wide duct 101.

A plurality of optical cables 19 are housed in the wide duct 101 laid along the wall surface Wa of the indoor wall W. The optical cable 19 is laid along the laying path 18 of the wide duct 101. Therefore, in the laying structure of the optical cable 19, the separating member 20 made of a material that transmits ultraviolet rays is fixed to the wall surface Wa of the indoor wall W, and the separating member 20 has a length that internally defines the laying path 18 of the optical cable 19. A wide duct 101 in the shape of a shaku is attached. In the laying structure of the optical cable 19, the optical cable 19 is laid inside the wide duct 101.

Next, the laying structure of the narrow duct 102 will be described.
As shown in FIG. 8, in the front view of the indoor wall W, the plurality of separating members 20 are fixed to the indoor wall W so that the narrow direction Y is the horizontal direction and the wide direction X is the vertical direction. Since the method of fixing each separating member 20 to the indoor wall W is the same as when laying the wide duct 101, detailed description thereof will be omitted.

As shown in FIG. 9, the plurality of separating members 20 are fixed to the indoor wall W at intervals in the vertical direction. Note that FIG. 9 shows only one separating member 20. A narrow duct 102 is attached to these plurality of separating members 20. The narrow duct 102 is laid so that the longitudinal axis extends in the vertical direction. Since the method of attaching the narrow duct 102 to the separating member 20 is the same as the method of attaching the wide duct 101 to the separating member 20, detailed description thereof will be omitted.

As shown in FIG. 10, the outer surface 12b of the bottom wall 12 of the narrow duct 102 is separated from the wall surface Wa of the indoor wall W by the thickness of the separating member 20. Therefore, in the outer surface 12b of the bottom wall 12 of the narrow duct 102, a gap S corresponding to the thickness of the separating member 20 is provided between the portion of the outer surface 12b that is not opposed to the separating member 20 and the wall surface Wa of the indoor wall W. Exists. The thickness of the separating member 20 is the sum of the thickness of the fixing portion 31 in the main body 21 and the thickness of the double-sided tape 41 protruding from the first end surface 31a.

The width W2 of the narrow duct 102 is the same as the dimension L2 of the main body 21. Therefore, when both end faces in the width direction of the narrow duct 102 and both end faces in the narrow direction Y of the main body 21 are aligned with each other in the front view of the indoor wall W, the narrow duct 102 is attached to the separating member 20. , The main body 21 is hidden behind the narrow duct 102. That is, the insertion hole 32 of the fixing portion 31 and the head portion 50a of the fixing nail 50 are covered with the narrow duct 102.

A plurality of optical cables 19 are housed in the narrow duct 102 laid along the wall surface Wa of the indoor wall W. The optical cable 19 is laid along the laying path 18 of the narrow duct 102.

Therefore, the separating member 20 exists between the indoor wall W and the optical cable 19 laid along the wall surface Wa of the indoor wall W via the wide duct 101 or the narrow duct 102. Further, the separating member 20 includes a main body 21 that separates the optical cable 19 in the wide duct 101 or the narrow duct 102 from the wall surface Wa, and the main body 21 is made of a material that transmits ultraviolet rays.

Therefore, in the laying structure of the optical cable 19, the separating member 20 made of a material that transmits ultraviolet rays is fixed to the wall surface Wa of the indoor wall W, and the separating member 20 has a length that internally defines the laying path 18 of the optical cable 19. A scale-shaped narrow duct 102 is attached. In the laying structure of the optical cable 19, the optical cable 19 is laid inside the narrow duct 102.

Next, the operation of the separation member 20, the laying structure of the optical cable 19, and the duct installation device 60 will be described.
A plurality of separating members 20 are fixed to the indoor wall W at intervals in the vertical direction, and are separated from the outer surface 12b of the bottom wall 12 of the wide duct 101 or the narrow duct 102 and the wall surface Wa of the indoor wall W. There is a gap S corresponding to the thickness of the member 20. That is, the wall surface Wa of the indoor wall W is not covered by the wide duct 101 or the narrow duct 102 except for the fixed portion of the separating member 20.

Therefore, in the wall surface Wa of the indoor wall W, the portion facing the outer surface 12b of the wide duct 101 or the narrow duct 102, that is, the laying path 18 of the optical cable 19 is also irradiated with ultraviolet rays. Therefore, in the wall surface Wa of the indoor wall W, the portion facing the wide duct 101 or the narrow duct 102 is also irradiated with ultraviolet rays, and the color changes with the irradiation of the ultraviolet rays.

Then, in the wall surface Wa of the indoor wall W, the portion where the separating member 20 is fixed is covered by the separating member 20, but the separating member 20 is a colorless and transparent material that transmits ultraviolet rays. Therefore, in the wall surface Wa of the indoor wall W, the portion where the separating member 20 is fixed is also irradiated with ultraviolet rays, and the color changes with the irradiation of the ultraviolet rays.

According to the first embodiment, the following effects can be obtained.
(1-1) By separating the optical cable 19 accommodated in the wide duct 101 or the narrow duct 102 from the indoor wall W by the separating member 20, the wide duct 101 or the wide duct 101 accommodating the optical cable 19 in the wall surface Wa of the indoor wall W. Ultraviolet rays are also irradiated to a portion facing the narrow duct 102 and where the separating member 20 is not fixed. Further, the main body 21 of the separating member 20 is made of a colorless and transparent synthetic resin material capable of transmitting ultraviolet rays. Therefore, in the wall surface Wa of the indoor wall W, the portion covered by the separating member 20 is also irradiated with ultraviolet rays. Therefore, in the wall surface Wa of the indoor wall W, the portion facing the wide duct 101 or the narrow duct 102 is also discolored by the irradiation of ultraviolet rays. That is, a clear difference between the color of the wall surface Wa at the location facing the laying path 18 of the optical cable 19 and the color of the wall surface Wa at the location adjacent to the laying path 18 is unlikely to occur. Therefore, when the optical cable 19 is removed from the indoor wall W together with the wide duct 101 or the narrow duct 102, or is relocated to another place, the wall surface Wa of the indoor wall W is discolored and the discoloration is suppressed. It is difficult for a boundary with the portion where the wall is formed to occur, and deterioration of the appearance of the indoor wall W can be suppressed.

(1-2) The main body 21 of the separating member 20 has a mounting portion 22 and a fixing portion 31. Then, a wide duct 101 or a narrow duct 102 is attached to the attachment portion 22. Therefore, by using the separating member 20, the optical cable 19 separated from the indoor wall W can be accommodated in the wide duct 101 or the narrow duct 102, and the optical cable 19 can be protected by the wide duct 101 or the narrow duct 102.

(1-3) The main body 21 of the separating member 20 has a short shape shorter than the dimension along the longitudinal axis of the wide duct 101 or the narrow duct 102. Therefore, even if the wide duct 101 or the narrow duct 102 is separated from the indoor wall W by using a plurality of separating members 20, the distance between the adjacent separating members 20 can be widened, and the wall surface Wa of the indoor wall W can be widened. Of these, the area covered by the separating member 20 can be reduced.

(1-4) Double-sided tape 41 is attached to the attachment surface 22a of the attachment portion 22. Therefore, the wide duct 101 or the narrow duct 102 is attached to the main body 21 by the double-sided tape 41. Therefore, the wide duct 101 or the narrow duct 102 can be attached to the main body 21 with a simple configuration such as the double-sided tape 41.

(1-5) The dimension L1 of the main body 21 in the wide direction X is the same as the width W1 of the wide duct 101, and the dimension L2 of the main body 21 in the narrow direction Y is the same as the width W2 of the narrow duct 102. Is. Therefore, when the separating member 20 is fixed to the indoor wall W so that the wide direction X of the main body 21 is in the horizontal direction and the wide duct 101 is attached to the double-sided tape 41 of the separating member 20, the separating member is attached by the wide duct 101. 20 can be covered. Similarly, when the separating member 20 is fixed to the indoor wall W so that the narrowing direction Y of the main body 21 is horizontal, and the narrow duct 102 is attached to the double-sided tape 41 of the separating member 20, the narrow duct 102 is attached. The separating member 20 can be covered by the 102. Therefore, it is possible to prevent the separating member 20 from protruding from the wide duct 101 or the narrow duct 102 and deteriorating the appearance.

(Second embodiment)
Next, a second embodiment embodying the separation member, the laying structure of the wiring / piping material, and the duct installation device will be described with reference to FIGS. 11 to 13. Since the second embodiment has a configuration in which the main body 21 of the first embodiment is modified, detailed description thereof will be omitted for the same parts.

As shown in FIGS. 11 or 12, the main body 21 has the same dimensions of the attachment portion 22 and the fixing portion 31 in the plate thickness direction Z. Therefore, the main body 21 has the same dimensions in the plate thickness direction Z except for the portion where the insertion hole 32 is provided. The dimension of the fixed portion 31 of the second embodiment in the wide direction X is the same as the dimension of the fixed portion 31 of the first embodiment in the wide direction X. The attachment portion 22 is a portion sandwiched between the two fixing portions 31.

The main body 21 is provided with one insertion hole 32 in each fixing portion 31. The insertion hole 32 of one fixing portion 31 and the insertion hole 32 of the other fixing portion 31 are misaligned in the narrow direction Y. The insertion hole 32 of one fixing portion 31 is located near one end in the narrow direction Y, and the insertion hole 32 of the other fixing portion 31 is located near the other end in the narrow direction Y.

The separating member 20 includes two legs 33 protruding from the second end surface 31b of each fixing portion 31. Each leg 33 has a round bar shape. The first end surface of each leg 33 is joined to the second end surface 31b of the fixing portion 31, and the second end surface of each leg 33 is a contact surface 33a of the indoor wall W with the wall surface Wa. The contact surface 33a is a flat surface. The length along the axis of the leg 33 is the same for all four legs 33. The length along the axis of the leg 33 may be appropriately changed according to the unevenness of the wall surface Wa of the indoor wall W. The legs 33 are arranged at the four corners of the main body 21.
