Description

[Technical field]

[0001] The present invention relates to a wall-embedded pipe cover. To Regarding. [Background technology]

[0002] Patent Document 1 discloses a protective cover for wiring and piping materials that houses and protects wiring and piping materials without exposing them along the wiring and piping path on a wall surface. The protective cover described in Patent Document 1 consists of a linear main cover and an accessory cover connected to the main cover. The main cover and the accessory cover each include a base that is in close contact with the surface of the wall and a lid that is fitted onto the base. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-16799 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the protective cover described in Patent Document 1 has a structure in which a lid is fitted to a base that is in close contact with the surface of a wall. Therefore, the entire protective cover protrudes from the surface of the wall. As a result, there are problems such as poor appearance and poor space efficiency around the protective cover.

[0005] An object of the present invention is to provide a wall-embedded pipe cover capable of minimizing the protruding height of the pipe cover from the surface of the wall. - The purpose is to provide. [Means for solving the problem]

[0006] In order to achieve the above object, a wall-embedded pipe cover is provided that is inserted into a slit formed in a wall, has an opening that opens toward the front side of the wall, and has a storage recess for storing a pipe member, and is formed on both sides of the storage recess and is attached to the wall in a state where it is overlapped on the surface of the wall. With screws The housing includes a base member having a flange portion to which the housing is fixed, and a flat decorative cover that is assembled to the base member, covers the opening of the accommodating recess, and is overlapped with the flange portion.

[0007] According to this configuration, the accommodating recess of the base member that accommodates the piping member is inserted into the slit formed in the wall, and the flange portion is assembled to the wall in a state where the flange portion is superimposed on the surface of the wall, so that the protruding height of the piping cover from the surface of the wall can be kept small.

[0008] In the wall-embedded pipe cover, the decorative cover has a cut surface, and preferably includes a cut surface cover that covers the cut surface of the decorative cover. The length of the base member and the decorative cover that constitute the pipe cover is determined according to the length of the pipe member to be housed. At the construction site, a worker cuts the decorative cover of a certain length to a length determined according to the length of the pipe member to perform construction. Therefore, if the cut surface of the decorative cover is exposed to the outside, the aesthetic appearance of the pipe cover may be impaired.

[0009] In this regard, according to the above-mentioned configuration, since the cut surface of the decorative cover is covered by the cut surface cover, the cut surface is not exposed to the outside, and the appearance of the piping cover can be improved. In the above-mentioned wall-embedded type piping cover, it is preferable that the accommodating recess of the base member has a pair of opposing side walls, and the outer surfaces of both of the side walls are planar and parallel to each other.

[0010] By fixing a pair of splints to the back surface of the wall on both sides of the slit along the extending direction of the slit, the peripheral portion of the wall around the slit can be reinforced. By fixing the flange portion of the base member to such a wall, the flange portion can be stably supported by the wall.

[0011] According to the above configuration, the outer surfaces of the pair of side walls constituting the receiving recess of the base member are parallel to each other, so that the outer surfaces of the pair of side walls are aligned with the side surfaces of the pair of splints arranged on both sides of the slit. This allows the base member to be positioned relative to the wall. This improves ease of installation when fixing the base member to the wall.

[0012] In the above-mentioned wall-embedded piping cover, the base member comprises a first base member that accommodates a pipe as the piping member, and a second base member that accommodates a fitting as the piping member, and the decorative cover comprises a first decorative cover assembled to the first base member, and a second decorative cover assembled to the second base member, and it is preferable that the first decorative cover has a cut surface and the cut surface is covered by the second decorative cover.

[0013] According to this configuration, in a front view of the piping cover, the first decorative cover and the second decorative cover are continuous, and the cut surface of the first decorative cover is covered by the second decorative cover. Therefore, it is possible to improve the appearance of the piping cover without providing a dedicated cover for covering the cut surface of the first decorative cover.

[0014] In the above-mentioned wall-embedded pipe cover, the base member and the decorative cover are provided above a baseboard provided at the bottom of the wall or below a molding provided at the top of the wall, and it is preferable that the protruding height of the decorative cover from the surface of the wall is less than or equal to the protruding height of the baseboard or the molding from the surface of the wall.

[0015] With this configuration, the decorative cover does not protrude beyond the baseboard, so the decorative cover does not get in the way when placing a washing machine or other appliance close to the wall. Therefore, the washing machine or other appliance can be placed with a small gap between the wall.

[0016] In addition, an installation method for a wall-embedded type piping cover to achieve the above-mentioned object includes the steps of forming a slit extending along a predetermined direction in the wall, fixing a splint to the rear surface of the wall along the extension direction of the slit, inserting the accommodating recess of the base member into the slit and fixing the flange portion to the wall in a manner such that the wall is sandwiched between the splint and the accommodating recess, and assembling the decorative cover to the base member.

[0017] According to this method, the splint is fixed to the rear surface of the wall along the extending direction of the slit, so that the peripheral portion of the wall around the slit is reinforced. By fixing the flange portion of the base member to such a wall, the flange portion can be stably supported by the wall. Effect of the Invention

[0018] According to the present invention, the protruding height of the piping cover from the surface of the wall can be kept small. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, one embodiment will be described with reference to Fig. 1 to Fig. 11. As shown in Fig. 1, a wall-embedded type piping cover (hereinafter, piping cover 10) includes a first base member 20, a first decorative cover 30, a second base member 40, a second decorative cover 50, a support member 60, and a cut surface cover 70.

[0021] Next, a detailed description will be given of each component of the piping cover 10. <First base member 20> As shown in Fig. 1, Fig. 2 and Fig. 4, the first base member 20 includes a gutter-shaped accommodating recess 21 that accommodates a pipe 81 as a piping member 80, and a pair of flange portions 27 formed on both sides of the accommodating recess 21 in the width direction.

[0022] The accommodating recess 21 has a long, flat bottom wall 22 and a pair of opposing side walls 23 that are bent and extend from both widthwise edges of the bottom wall 22. Both outer surfaces of the side walls 23 are planar and parallel to each other.

[0023] On the inner surface of each side wall 23, in order from closest to the bottom wall 22, a pair of first ridges 24, a pair of second ridges 25, and a pair of third ridges 26 extend along the longitudinal direction of the bottom wall 22 and throughout the entire longitudinal direction.

[0024] The first ridges 24, the second ridges 25, and the third ridges 26 face each other in the width direction of the accommodating recess 21. Each flange portion 27 extends outward in the width direction of the accommodating recess 21 from the outer surface of the tip of each side wall 23. Each flange portion 27 has a plurality of screw holes 28 formed at intervals.

[0025] The first base member 20 is integrally molded from a hard resin material. The first base member 20 of this embodiment is formed by extrusion molding. <First decorative cover 30> As shown in Figs. 1, 3 and 4, the first decorative cover 30 has a flat cover body 31 that covers the opening 21a of the accommodating recess 21 and is overlapped with the flange portion 27, and a pair of protrusions 32 formed on the back surface of the cover body 31.

[0026] The cover body 31 has a rectangular shape when viewed from the front. Both widthwise ends of the cover body 31 are curved so that the outer sides in the widthwise direction are located toward the back side of the cover body 31. Each protrusion 32 extends along the longitudinal direction of the cover body 31 and over the entire longitudinal direction.

[0027] The ridges 32 are inclined so as to approach each other as they move away from the cover body 31. A locking claw 33 is formed at the tip of each ridge 32. The locking claws 33 are inclined so as to move away from each other as they move away from the cover body 31.

[0028] Both ends of the first decorative cover 30 in the longitudinal direction are cut surfaces 30a. As shown in Fig. 4, the first decorative cover 30 is assembled to the first base member 20 by engaging the locking claws 33 with the third protrusions 26 of the first base member 20. At this time, a gap S is formed between the cover body 31 and each flange portion 27.

[0029] The first decorative cover 30 is integrally molded from a hard resin material. The first decorative cover 30 of this embodiment is formed by extrusion molding. <Second base member 40> As shown in Fig. 1 and Fig. 5, the second base member 40 has an accommodating recess 41 that accommodates a joint 82 as a piping member 80, and flange portions 47 formed on both sides of the accommodating recess 41.

[0030] The accommodation recess 41 has a bottom wall 42 and a side wall 43 that is bent and extends from an edge of the bottom wall 42 and has an inverted U-shape when viewed from the front. As shown in Fig. 5, a recess 42a for allowing the rear portion of the joint 82 to escape is formed on the surface of the bottom wall 42.

[0031] A plurality of screw holes 45 are formed at intervals in a portion surrounding the recess 42a in the bottom wall 42. The flange portion 47 extends from the outer surface of the tip of the side wall 23 outward in the width direction and toward the opposite side from the first base member 20. The flange portion 47 is provided with a plurality of screw holes 48 and a plurality of engagement holes 49 at intervals.

[0032] The second base member 40 has a bottom wall 42 and the side wall 43 have extensions 44 extending toward the first base member 20. The second base member 40 is integrally molded from a hard resin material. In this embodiment, the second base member 40 is formed by injection molding.

[0033] <Second decorative cover 50> As shown in Figures 1 and 6, the second decorative cover 50 has a flat cover body 51 that covers the opening 41a of the accommodating recess 41 and is overlapped on the flange portion 47, and a plurality of engagement claws 52 formed on the back surface of the cover body 51.

[0034] The cover body 51 has a generally rectangular shape in a front view. Of the four edges of the cover body 51, three edges 51b, excluding an edge 51a that overlaps with the first decorative cover 30, are bent and protrude toward the rear side.

[0035] When the second decorative cover 50 is attached to the second base member 40, the edge 51b is located on the outer periphery of the flange portion 47 of the second base member 40. An insertion hole 51c is provided in the center of the cover body 51 to allow a faucet or the like to be connected to the joint 82 to pass through.

[0036] The second decorative cover 50 is integrally molded from a hard resin material. The second decorative cover 50 of this embodiment is formed by injection molding. <Supporting member 60> As shown in Figures 1, 2 and 4, the supporting member 60 is detachably provided on the first base member 20 and supports the pipe 81, and has a base plate 61, a pair of restricting projections 62 protruding from the surface of the base plate 61, and a supporting portion 63 protruding from the surface of the base plate 61 and supporting the pipe 81.

[0037] The base plate 61 has a rectangular shape when viewed from the front, and a long hole 61a that is long in the longitudinal direction of the base plate 61 is formed in the center thereof. A pair of corners 61b at diagonal positions of the base plate 61 are right-angled, while the remaining pair of corners 61c are rounded into an arc shape when viewed from the front. In this embodiment, the pair of corners 61c are located at the upper left and lower right when viewed from the front when attached to the first base member 20.

[0038] A pair of fitting protrusions 61d are formed on both longitudinal ends of the surface of the base plate 61. As shown in Fig. 4, both longitudinal ends of the base plate 61 are fitted between the bottom wall 22 of the first base member 20 and the pair of first protrusions 24, whereby the support member 60 is attached to the first base member 20.

[0039] 2, with the longitudinal direction of the support member 60 aligned with the longitudinal direction of the first base member 20, the support member 60 is rotated 90 degrees clockwise in a front view while being abutted against the bottom wall 22. As a result, both longitudinal end portions of the base plate 61, more specifically, the portions where the pair of fitting protrusions 61d are provided, are fitted between the bottom wall 22 of the first base member 20 and the pair of first ridges 24.

[0040] As described above, the pair of corners 61c of the base plate 61 are rounded into an arc shape when viewed from the front, which allows the support member 60 to rotate clockwise when viewed from the front from the position shown by the two-dot chain line in FIG.

[0041] 2, further rotation of the support member 60 is prevented by the pair of corners 61b abutting against the pair of side walls 23. On the other hand, rotation of the support member 60 in the counterclockwise direction as viewed from the front from the position shown by the two-dot chain line in FIG. 2 is prevented by the pair of corners 61b abutting against the pair of side walls 23.

[0042] The pair of regulating protrusions 62 regulate the fitting allowance when both longitudinal ends of the base plate 61 are fitted between the bottom wall 22 of the first base member 20 and a pair of first protrusions 24, and are provided on both longitudinal sides of the base plate 61 and extend along the width direction of the base plate 61.

[0043] The support portion 63 is provided in the center of the base plate 61 in the longitudinal direction, and has a concave surface with an arc-shaped cross section on its surface for supporting the pipe 81. The support portion 63 is provided across the entire base plate 61 in the width direction.

[0044] The support member 60 is integrally molded from a hard resin material. The support member 60 of this embodiment is formed by injection molding. <Cut Surface Cover 70> As shown in Fig. 1, the cut surface cover 70 covers the cut surface 30a of the first decorative cover 30 and is substantially flat.

[0045] The cut surface cover 70 has a generally rectangular shape in a front view that is long in the width direction of the cover body 31 of the first decorative cover 30. The longitudinal edges of the cut surface cover 70 are bent and protrude toward the rear side.

[0046] The cut surface cover 70 is integrally molded from a hard resin material. The cut surface cover 70 of this embodiment is formed by injection molding. Next, a method for installing the piping cover 10 will be described with reference to Figs. 7 to 11. In this embodiment, a method for installing the piping cover 10 that houses the piping members 80 extending upward from piping arranged under the floor of a house or the like, that is, the so-called underfloor piping, will be described.

[0047] First, as shown in Fig. 7, a slit 91 extending in the up-down direction is formed in a wall 90. The slit 91 extends to the bottom of the wall 90. A baseboard 93 extending in the width direction of the slit 91 (the horizontal direction in the figure) is fixed to the bottom of the surface of the wall 90 by a nail or the like (not shown). The lower end of the slit 91 is covered by the baseboard 93 from the front side.

[0048] The upper end of the slit 91 is formed in an arc shape when viewed from the front. Next, a pair of splints 92 are fixed to the rear surface of the wall 90 along the extension direction of the slit 91. More specifically, the splints 92 made of a pair of square timbers are fixed to both sides of the wall 90 in the width direction of the slit 91. A screw 94 is inserted from the front side into a hole 90a formed in the wall 90, and the screw 94 is screwed into the splint 92, thereby fixing the splint 92 to the wall 90.

[0049] 8, the second base member 40 is inserted into the upper portion of the slit 91, and the flange portions 47 are fixed to the wall 90 in such a manner that the wall 90 is sandwiched between the second base member 40 and the splint 92. The opening 41a of the accommodation recess 41 opens toward the front side of the wall 90, and the pair of flange portions 47 are fixed to the wall 90 in a state where they are overlapped on the surface of the wall 90. More specifically, the screws 95 are inserted into the screw holes 48 of the flange portions 47 from the front side, and the screws 95 are screwed into the wall 90 and the splint 92, thereby fixing the second base member 40 to the wall 90.

[0050] Next, the accommodating recess 21 of the first base member 20 is inserted into the lower part of the slit 91, and the flange portion 27 is fixed to the wall 90 in a manner that the wall 90 is sandwiched between the accommodating recess 21 and the splint 92. The opening 21a of the accommodating recess 21 opens toward the front side of the wall 90, and the pair of flange portions 27 are fixed to the wall 90 in a state where they are overlapped on the surface of the wall 90. More specifically, the screw 96 is inserted into the screw hole 28 of the flange portion 27 from the front side, and the screw 96 is screwed into the wall 90 and the splint 92, thereby fixing the first base member 20 to the wall 90.

[0051] An upper end of the accommodating recess 21 of the first base member 20 overlaps with the front side of the extending portion 44 of the second base member 40. Next, as shown in Fig. 9, a pipe 81 is accommodated in the accommodating recess 21 of the first base member 20, and a joint 82 is accommodated in the accommodating recess 41 of the second base member 40. At this time, the pipe 81 is supported by the two support members 60 attached to the accommodating recess 21. Specifically, the pipe 81 is fastened to the support members 60 via a cable tie (not shown) inserted through the long hole 61a of the support members 60.

[0052] Furthermore, a screw 97 is inserted into a mounting seat (not shown) of the joint 82 and screwed into the screw hole 45 of the accommodating recess 41, thereby fixing the joint 82 to the accommodating recess 41. Next, as shown in Fig. 10, the first decorative cover 30 is assembled to the first base member 20. Next, the second decorative cover 50 is assembled to the second base member 40. As a result, the cut surface 30a at the upper end of the first decorative cover 30 is covered by the second decorative cover 50.

[0053] Also, a cut surface cover 70 is attached so as to cover the cut surface 30a at the lower end of the first decorative cover 30. The cut surface cover 70 is fixed to the surface of the first decorative cover 30 via, for example, double-sided tape or adhesive.

[0054] As shown in Figures 11(a) and 11(b), the protruding heights of the first decorative cover 30, the second decorative cover 50 and the cut surface cover 70 from the surface of the wall 90 are less than the protruding height of the baseboard 93 from the surface of the wall 90.

[0055] Next, the effects of this embodiment will be described. (1) The accommodating recesses 21, 41 of the base members 20, 40 that accommodate the piping member 80 are inserted into the slits 91 formed in the wall 90, and the flange portions 27, 47 are fixed to the wall 90 in a state in which the flange portions 27, 47 are superimposed on the surface of the wall 90. Therefore, the protruding height of the piping cover 10 from the surface of the wall 90 can be kept small.

[0056] (2) The length of the first base member 20 and the first decorative cover 30 constituting the piping cover 10 is determined according to the length of the piping member 80 to be housed. At the construction site, a worker cuts the first base member 20 and the first decorative cover 30, each having a fixed length (for example, 2 to 3 m), to a predetermined length determined according to the length of the piping member 80, and performs construction. Therefore, if the cut surface 30a of the first decorative cover 30 is exposed to the outside, the aesthetic appearance of the piping cover 10 may be impaired.

[0057] In this regard, according to the above configuration, the cut surface 30a of the first decorative cover 30 is covered by the cut surface cover 70, so that the cut surface 30a is not exposed to the outside, and the appearance of the piping cover 10 can be improved.

[0058] (3) If a pair of splints 92 are fixed to portions of the rear surface of the wall 90 located on both sides of the slit 91 along the extending direction of the slit 91, the peripheral portion of the wall 90 around the slit 91 is reinforced. If the flange portion 27 of the first base member 20 is fixed to such a wall 90, the flange portion 27 can be stably supported by the wall 90.

[0059] According to the above configuration, the outer surfaces of the pair of side walls 23 constituting the accommodating recess 21 of the first base member 20 are planar and parallel to each other, so that the outer surfaces of the pair of side walls 23 run along the side surfaces of the pair of splints 92 arranged on both sides of the slit 91. This allows the first base member 20 to be positioned relative to the wall 90. This makes it possible to improve the ease of construction when fixing the first base member 20 to the wall 90.

[0060] (4) The first decorative cover 30 has a cut surface 30a, and the cut surface 30a is covered by the second decorative cover 50. According to this configuration, in a front view of the piping cover 10, the first decorative cover 30 and the second decorative cover 50 are continuous, and the cut surface 30a of the first decorative cover 30 is covered by the second decorative cover 50. Therefore, the appearance of the piping cover 10 can be improved without providing a dedicated cover for covering the cut surface 30a of the first decorative cover 30.

[0061] (5) The protruding height of the decorative covers 30, 50 and the cut surface cover 70 from the surface of the wall 90 is equal to or less than the protruding height of the baseboard 93 from the surface of the wall 90. With this configuration, the decorative covers 30, 50 and the cut surface cover 70 do not protrude forward beyond the baseboard 93, so that the decorative covers 30, 50 and the cut surface cover 70 do not get in the way when a washing machine or the like is placed close to the wall 90. Therefore, the washing machine or the like can be placed with a small distance from the wall 90.

[0062] (6) The installation method of the pipe cover 10 includes a step of forming a slit 91 extending in the up-down direction in the wall 90, and a step of fixing a splint to the rear surface of the wall 90 along the extension direction of the slit 91. The installation method also includes a step of inserting the accommodating recesses 21, 41 of the base members 20, 40 into the slits 91 and fixing the flange portions 27, 47 to the wall 90 in a manner that the wall 90 is sandwiched between the accommodating recesses 21, 41 and the splint 92, and a step of assembling the decorative covers 30, 50 to the base members 20, 40.

[0063] According to this method, the splint 92 is fixed to the back surface of the wall 90 along the extending direction of the slit 91. This reinforces the peripheral edge of the slit 91. By fixing the flange portions 27, 47 of the base members 20, 40 to such a wall 90, the flange portions 27, 47 can be stably supported by the wall 90.

[0064] (7) A plurality of screw holes 28 are provided at intervals in each flange portion 27 of the first base member 20. With this configuration, when each flange portion 27 is fixed to the wall 90, the screws 94 already driven into the wall 90 can be visually observed through the screw holes 28. This makes it possible to avoid driving screws 96 in positions that overlap with the screws 94.

[0065] In addition, when cutting the first base member 20 of a fixed length to a specified length determined according to the length of the piping member 80, the first base member 20 can be cut while checking the position of the screw 94 through the screw hole 28 of the first base member 20 so that the position of the screw 94 already installed in the wall 90 does not overlap with the position of the screw hole 28.

[0066] (8) The upper end of the slit 91 is formed in an arc shape when viewed from the front. This reduces stress concentration at the upper end of the slit 91 in the wall 90. This makes it possible to effectively prevent cracks from occurring in the wall 90.

[0067] (9) The outer peripheral surface of the side wall 43 of the second base member 40 is inverted U-shaped when viewed from the front. Therefore, whether the shape of the upper end of the slit 91 is an arc shape when viewed from the front as in this embodiment or a rectangular shape when viewed from the front, the accommodating recess 41 of the second base member 40 can be inserted for construction.

[0068] (Modifications) The above embodiment can be modified as follows, for example. This embodiment and the following modifications can be combined to the extent that no technical contradiction occurs. The shape of the upper end of the slit 91 is not limited to an arc shape when viewed from the front. For example, the slit can be rectangular when viewed from the front. In this case, the slit can be easily formed in the wall 90.

[0069] 12(a) and 12(b) has a pair of engagement portions 46 protruding to the front side on the bottom wall 42. The pair of engagement portions 46 are provided side by side on the first base member 20 side with respect to a pair of screw holes 45 formed on either side of the recess 42a in the width direction. Note that in the second base member 40 shown in FIG. 12, configurations that are the same as or correspond to those in the above embodiment are given the same reference numerals and redundant explanations will be omitted.

[0070] As shown in Figures 13(a) and 13(b), the fitting 82 used with the modified second base member 40 is, similar to the above embodiment, an elbow-shaped fitting having a first connection port 82a to which the pipe 81 is connected and a second connection port 82b to which a faucet (not shown) is connected, and has multiple mounting seats 83A, 83B.

[0071] Specifically, the multiple mounting seats 83A, 83B include one mounting seat 83A protruding from the main body of the joint 82 toward the side opposite to the first connection port 82a (the upper side in the figure), and a pair of mounting seats 83B protruding from the main body toward the outside in the width direction. Each of the mounting seats 83A, 83B is open toward the tip in the protruding direction and is formed with an insertion portion 83a through which a screw 97 is inserted.

[0072] Next, as shown in Fig. 14, a process of attaching the piping member 80 to the second base member 40 will be described. First, as shown in Fig. 14(a), a screw 97 is temporarily fastened into the uppermost screw hole 45 of the second base member 40. At this time, the distance between the head of the screw 97 and the bottom wall 42 of the second base member 40 is larger than the thickness of the mounting seat 83A of the joint 82.

[0073] Next, while tilting the joint 82 with respect to the second base member 40, the insertion portion 83a of the mounting seat 83A is inserted into the portion between the head of the screw 97 and the bottom wall 42 of the second base member 40. This causes the joint 82 to be temporarily held on the second base member 40. At this time, the upper end of the pipe 81 is connected to the first connection port 82a of the joint 82.

[0074] 14(b), the joint 82 is pushed into the recess 42a. As a result, the pair of left and right mounting seats 83B come into contact with the bottom wall 42 of the second base member 40 and also come into contact with the upper surfaces of the pair of engagement portions 46, thereby engaging with the second base member 40.

[0075] 14(c), the temporarily tightened screws 97 are fully tightened, and the pair of screws 97 are inserted into the insertion portions 83a of the pair of left and right mounting seats 83B and screwed into the screw holes (not shown). In this manner, the joint 82 is assembled to the second base member 40.

[0076] According to this configuration, the joint 82 can be temporarily held on the second base member 40, so that the worker does not need to hold down the joint 82 with one hand when screwing in the screw 97. Therefore, the ease of installation of the joint 82 can be improved.

[0077] The screw holes 28 provided in each flange portion 27 of the first base member 20 may be omitted. In this case, a worker at the construction site will determine the positions in the flange portions 27 where the screws 96 are screwed in. At this time, as shown in Fig. 9, for example, it is preferable to form protrusions 29 extending along the longitudinal direction (the vertical direction in the figure) on the surface of each flange portion 27 as markers for the positions where the screws 96 are screwed in.

[0078] In the above embodiment, the slits 91 were formed in the wall 90 along the vertical direction in order to arrange the piping member 80 along the vertical direction. However, for example, when the piping member 80 is arranged along the left-right direction perpendicular to the up-down direction, the slits 91 may be formed along the left-right direction.

[0079] In the above embodiment, a pair of splints 92 are fixed to the back surface of the wall 90, but one or both of the splints 92 may be omitted. For example, the protruding height of the second decorative cover 50 and the cut surface cover 70 from the surface of the wall 90 may be greater than the protruding height of the baseboard 93 from the surface of the wall 90. The same applies to the first decorative cover 30.

[0080] In the above embodiment, the installation method of the piping cover 10 that houses the piping member 80 extending upward from the underfloor piping has been described, but the present invention can also be embodied as an installation method of a piping cover that houses piping arranged above the ceiling, i.e., piping members extending downward from the so-called ceiling piping. In this case, the base members 20, 40 and the decorative covers 30, 50 are provided below the molding provided at the top of the wall 90. Even in this case, if the protruding height of the decorative covers 30, 50 and the cut surface cover 70 from the surface of the wall 90 is set to be equal to or less than the protruding height of the molding from the surface of the wall 90, the same effect as effect (5) of the above embodiment can be achieved.

[0081] The cut surface 30a at the upper end of the first decorative cover 30 may not be covered by the second decorative cover 50. In this case, a dedicated cover for covering the cut surface 30a at the upper end of the first decorative cover 30 may be provided.

[0082] The pair of side walls 23 of the first base member 20 may be closer to each other as they approach the bottom wall 22. The same applies to the second base member 40. The number of support members 60 can be changed as appropriate. Also, the support members 60 can be omitted.

[0083] For example, if the lower end of the first decorative cover 30 is not the cut surface 30a, the cut surface cover 70 may be omitted.

[0084] 15 and 16, in the process of inserting the accommodating recess 21 of the first base member 20 into the slit 91 of the wall 90 and fixing the flange portion 27 of the first base member 20 to the wall 90, an opening correction jig 100 is used to correct the dimensions of the opening of the accommodating recess 21. In this way, it is possible to easily assemble the first decorative cover 30 to the first base member 20 and to reliably fit the first base member 20 and the first decorative cover 30 together at a high level. This will be described in detail below.

[0085] The first base member 20, which is thin and made of a resin material, is easily deformed by external forces acting on the flange portion 27 during installation, such as when screwing in the screws 96, and the width of the opening 21a of the accommodating recess 21, which has particularly low rigidity, in other words, the distance between the pair of side walls 23 on the opening 21a side, becomes wider or narrower than the specified value L.

[0086] When the distance between the pair of side walls 23 on the opening 21a side becomes wider than the specified value L, the distance between the pair of third ridges 26 located on the opening 21a side becomes wider than the specified value. When the first base member 20 is fixed to the wall 90 with the screws 96 in a state in which the distance between the pair of third ridges 26 becomes wider than the specified value, the engagement of the locking claws 33 with the third ridges 26, i.e., the fit between the first base member 20 and the first decorative cover 30, becomes loose, and the first base member 20 becomes more likely to fall off the first decorative cover 30.

[0087] Conversely, when the distance between the pair of side walls 23 on the opening 21a side becomes narrower than the specified value L, the distance between the pair of third ridges 26 located on the opening 21a side becomes narrower than the specified value. When the first base member 20 is fixed to the wall 90 with the screws 96 in a state in which the distance between the pair of third ridges 26 is narrower than the specified value, the engagement of the locking claws 33 with the third ridges 26, i.e., the fit between the first base member 20 and the first decorative cover 30, becomes difficult, making it difficult to assemble the first decorative cover 30 to the first base member 20.

[0088] The opening correction jig 100 is for correcting the opening 21a of the accommodating recess 21 in the first base member 20 so that the width of the opening 21a is a specified value L. The opening correction jig 100 is formed integrally from a synthetic resin material with an insertion portion 110 for preventing the width of the opening 21a of the accommodating recess 21 from becoming less than the specified value L and a restraint portion 120 for preventing the width of the opening 21a of the accommodating recess 21 from exceeding the specified value L.

[0089] The insertion portion 110 has an insertion plate 111 having the same width as the specified value L, and an engagement plate 112 connected to the insertion plate 111 and having a width smaller than the specified value L. Engagement recesses 112a are formed on both end faces in the width direction of the engagement plate 112. The plate thickness of the insertion plate 111 is 10 to 30% of the regulated value L.

[0090] The restraining portion 120 has a pair of restraining plates 121 respectively protruding from both end faces in the width direction of the insertion plate 111. Each restraining plate 121 is bent in a crank shape near the insertion plate 111, and a restraining recess 121a is formed by the bent portion and the end face of the insertion plate 111. The width of each restraining recess 121a is approximately the same as the width of the rib 21b that protrudes from the flange portion 27 in the first base member 20 to form the opening 21a. The thickness of the tip of each restraining plate 121 is approximately the same as or smaller than the gap S (see FIG. 4) between the cover body 31 and the flange portion 27.

[0091] The opening correction jig 100 is attached to the first base member 20 near the screw hole 28 before the first base member 20 is fixed to the wall 90 by the screw 96. The attachment is performed by inserting the insertion portion 110 of the opening correction jig 100 into the opening 21a of the accommodating recess 21 of the first base member 20. When the insertion portion 110 is inserted into the opening 21a of the accommodating recess 21 to a predetermined position, each rib 21b is inserted into the corresponding restraining recess 121a.

[0092] When the insertion portion 110 is inserted to a predetermined position into the opening 21a of the accommodation recess 21, the engagement recess 112a of the engagement plate 112 engages with the corresponding second protrusion 25, so that the opening correction jig 100 can be maintained in an attached state to the first base member 20 even without support from an operator. Also, since the plate thickness of the insertion plate 111 is appropriately large at 10 to 30% of the regulated value L, the insertion force of the insertion plate 111 into the opening 21a can be reduced while stabilizing the posture of the insertion plate 111 when inserted into the opening 21a, and the opening correction jig 100 does not fall over during the insertion, resulting in good workability.

[0093] Now, if the width of the opening 21a is smaller than the specified value L before the opening correction jig 100 is inserted, the width is corrected by inserting the insertion plate 111 and widened to the specified value L. If the width of the opening 21a is larger than the specified value L before the opening correction jig 100 is inserted, the width is corrected by inserting the corresponding rib 21b into each restraining recess 121a and narrowed to the specified value L. do.

[0094] If the first base member 20 is fixed to the wall 90 by screwing the screws 96 into the flange portions 27 (screw holes 28) while the opening correction jig 100 is attached, the width of the opening 21a will be maintained at the specified value L even after the opening correction jig 100 is removed. By repeating such correction work near the corresponding pairs of screw holes 28 using one opening correction jig 100, or by attaching a dedicated opening correction jig 100 to each corresponding pair of screw holes 28, the width of the opening 21a will not deviate from the specified value L as a whole in the longitudinal direction of the first base member 20.

[0095] In addition, when the correction work is performed with one opening correction jig 100, the opening correction jig 100 may be slid in the longitudinal direction of the first base member 20 while remaining inserted in the first base member 20 to the vicinity of the next pair of screw holes 28. Since the plate thickness of the insertion plate 111 is appropriately increased to 10 to 30% of the regulated value L, the opening correction jig 100 does not fall over when it is slid to the vicinity of the next pair of screw holes 28, and this improves workability.

[0096] Here, as shown in Figure 16, when the opening correction jig 100 is attached, if the screw 96 is properly screwed into the flange portion 27 (screw hole 28) and the amount by which the screw 96 protrudes from the flange portion 27 is less than the thickness of the tip of the corresponding restraint plate 121, it can be known in advance that the protruding portion of the screw 96 from the flange portion 27 will fit within the gap S between the cover body 31 and the flange portion 27, in other words, that the protruding portion will not hinder the assembly of the first decorative cover 30 to the first base member 20.

[0097] Conversely, although not shown, if the screw 96 is not sufficiently screwed into the flange portion 27 (screw hole 28) when the opening correction jig 100 is attached and the amount by which the screw 96 protrudes from the flange portion 27 is greater than the thickness of the tip of the corresponding restraint plate 121, it can be known in advance that the protruding portion of the screw 96 from the flange portion 27 will not fit into the gap S between the cover body 31 and the flange portion 27, in other words, that the protruding portion will hinder the assembly of the first decorative cover 30 to the first base member 20.

[0098] 17 and 18 show a modified example of the opening correction jig 100. In the modified opening correction jig 100, each restraining plate 121 is bent at a right angle near the tip, not near the insertion plate 111, and a restraining recess 121a is formed by the bent part and the end face of the insertion plate 111. The width of each restraining recess 121a is approximately the same as the sum of the width of the corresponding flange portion 27 and the width of the rib 21b.

[0099] When the insertion portion 110 is inserted to a predetermined position into the opening 21a of the accommodation recess 21, each flange portion 27 and each rib 21b is inserted into the corresponding restraining recess 121a. Then, if the width of the opening 21a is larger than the specified value L before the opening correction jig 100 is inserted, the width is corrected and narrowed to the specified value L by inserting the corresponding flange portion 27 and rib 21b into each restraining recess 121a.

[0100] When the opening correction jig 100 is attached, a gap is formed between each of the restraint plates 121 and the corresponding flange portion 27. The gap is approximately the same as or smaller than the gap S between the cover body 31 and the flange portion 27.

[0101] 18, if the screw 96 is properly screwed into the flange portion 27 (threaded hole 28) and the amount of protrusion of the screw 96 from the flange portion 27 is less than the gap S between the cover body 31 and the flange portion 27, even if the opening correction jig 100 is moved in the longitudinal direction of the first base member 20, the movement will not be hindered by the protruding portion of the screw 96 from the flange portion 27. From this, it can be known in advance that the protruding portion of the screw 96 from the flange portion 27 will fit into the gap S between the cover body 31 and the flange portion 27, in other words, that the protruding portion will not hinder the assembly of the first decorative cover 30 to the first base member 20.

[0102] Conversely, although not shown, if the screw 96 is not sufficiently screwed into the flange portion 27 (threaded hole 28) and the amount by which the screw 96 protrudes from the flange portion 27 is greater than the gap S between the cover body 31 and the flange portion 27, when the opening correction jig 100 is moved in the longitudinal direction of the first base member 20, the movement is hindered by the protruding portion of the screw 96 from the flange portion 27. From this, it can be known in advance that the protruding portion of the screw 96 from the flange portion 27 will not fit into the gap S between the cover body 31 and the flange portion 27, in other words, that the protruding portion will hinder the assembly of the first decorative cover 30 to the first base member 20.

[0103] (Additional Note) The technical idea that can be understood from the above embodiment is as follows: in the wall-embedded pipe cover described in any one of claims 1 to 5, an opening correction jig is used in the process of fixing the flange portion of the base member to the wall with screws, for correcting the width of the opening of the accommodating recess, the opening correction jig having a judgment means for judging whether the amount of protrusion of the screw from the flange portion is appropriate when attached to the base member.
