Description

[Technical field]

[0001] The present invention relates to a cover for a pipe joint. [Background technology]

[0002] In a cold water and hot water supply system for a building or the like, when a pipe fitting is connected to a pipe installed along a wall surface, it is considered to cover the pipe fitting with a pipe fitting cover as in Patent Document 1. This pipe fitting cover has a main body part in which an accommodation space for accommodating the pipe fitting is formed. The main body part has an opening part formed therein through which a pipe connected to the pipe fitting passes when the pipe fitting is accommodated in the accommodation space. The opening part is connected to the accommodation space of the main body part.

[0003] Therefore, when the pipe fitting is covered with the pipe fitting cover, the pipe fitting is accommodated in the accommodation space of the main body, and the pipe connected to the pipe fitting is also accommodated in the accommodation space. The pipe extends from inside the accommodation space to the outside through the opening. Since the pipe fitting is larger than the pipe, the accommodation space that accommodates them becomes wider the further away from the opening. With the pipe fitting and the pipe accommodated in the accommodation space of the main body in this way, the pipe fitting cover is fixed to the wall surface with screws or the like.

[0004] In some cases, the pipes arranged along the wall surface are covered with a piping cover. In this case, when the pipe joint is covered with the pipe joint cover, the pipe joint is accommodated in the accommodation space of the main body, and the pipe connected to the pipe joint and the piping cover covering the pipe are also accommodated in the accommodation space. In this case, the piping cover is inserted into the opening of the main body. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-122508 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, since the accommodation space of the pipe joint cover is wider as it is farther from the opening, when the pipe cover is inserted into the opening, the contact area of ​​the opening with the pipe joint cover tends to be smaller. As a result, the pipe joint cover tends to move in a direction rotating around the opening relative to the pipe cover, in other words, the pipe joint cover tends to tilt relative to the pipe cover. Since the pipe joint cover tends to tilt relative to the pipe cover in this way, it becomes difficult to determine the fixing position when fixing the pipe joint cover to a wall surface with screws or the like. [Means for solving the problem]

[0007] The means for solving the above problems and their effects will be described below. A pipe fitting cover that solves the above problem covers a pipe fitting connected to a pipe provided along a wall surface. The pipe fitting cover includes a main body portion having an accommodation space formed therein for accommodating the pipe fitting. The main body portion is formed with a connection port into which a piping cover that covers the pipe is inserted. The main body portion has an appearance that, in the vicinity of the connection port, becomes wider in a direction along the wall surface as it moves from the connection port toward the pipe fitting. The accommodation space, in the vicinity of the connection port, differs from the appearance and has a shape that extends from the connection port toward the pipe fitting with a constant width.

[0008] According to the above configuration, when the pipe joint is covered with the pipe joint cover, the pipe joint is accommodated in the accommodation space of the main body, and the pipe connected to the pipe joint and the piping cover covering the pipe are also accommodated in the accommodation space. At this time, the piping cover is inserted into the insertion opening of the main body. Then, a portion near the connection opening in the accommodation space, i.e., a portion that has a shape that tends to have a constant width from the connection opening toward the pipe joint, abuts against the piping cover along the direction from the connection opening toward the pipe joint. This makes it possible to prevent the pipe joint cover from tilting relative to the piping cover, in other words, to prevent the pipe joint cover from easily moving in a direction rotating around the connection opening relative to the piping cover.

[0009] In the pipe joint cover, the main body is formed to open the accommodation space toward the wall surface and also open the connection port. A flange is formed at the opening of the main body that opens toward the wall surface and protrudes outward from the opening. Ribs are formed on the flange on both sides of the width direction of the connection port, extending in a direction from the connection port toward the pipe joint. The shape of the accommodation space near the connection port that extends at a constant width from the connection port toward the pipe joint is realized by the ribs.

[0010] According to the above-mentioned configuration, since the rib is formed on the flat flange, the formation of the rib is facilitated. In the pipe joint cover, a protrusion is formed on the flange of the main body, protruding from a tip in a protruding direction relative to the main body toward the wall surface. The rib is connected to the protrusion at an end on the connection port side at an acute angle, thereby extending in a direction from the connection port toward the pipe joint side.

[0011] According to the above-mentioned configuration, the rib is connected to the protruding portion of the flange at an acute angle, thereby increasing the rigidity of the flange. [Brief description of the drawings]

[0013] Hereinafter, one embodiment of a pipe joint cover will be described with reference to Figs. 1 shows the appearance of a piping system 11 to which a pipe joint cover is applied. The piping system 11 includes pipes 12, 13, pipe joints 14-17, 19, 20, a faucet 21, a piping cover 22, an adapter 23, pipe joint covers 24-28, 30, 31, and a connection cover 29.

[0014] It is possible to adopt pipes having a covering material as the pipes 12 and 13. The pipe 12 is provided along a wall surface 32a of the wall 32, and the pipe 13 is provided so as to penetrate the wall 32.

[0015] The pipe joint 14 is connected to the pipes 12, 13 to connect the pipes 12 and 13. The pipe joint 15 is connected to the pipes 12 extending in different directions along the wall surface 32a to connect the pipes 12. The pipe joint 16 is connected to the pipes 12 and the faucet 21 to connect the pipes 12 and the faucet 21. The pipe joint 17 is connected to the pipes 12 extending on the same axis to connect the pipes 12. The pipe joint 19 is connected to each pipe 12 to connect the pipes 12 extending on the same axis and to connect the pipes 12 extending in a direction perpendicular to the pipes 12. The pipe joint 20 is connected to the pipes 12 extending in a direction perpendicular to the wall surface 32a to connect the pipes 12 extending in a direction perpendicular to the wall surface 32a.

[0016] The piping cover 22 is for covering the pipe 12. The adapter 23 is for blocking the longitudinal end of the piping cover 22 while allowing the pipe 12 to pass through. The pipe joint covers 24-28, 30, 31 are for covering the above-mentioned pipe joints 14-17, 19, 20. The pipe joint covers 24-28, 30, 31 also cover the longitudinal end of the pipe 12. By fixing the pipe joint covers 24-28, 30, 31 to the wall surface 32a in this state, the piping cover 22 is attached to the wall surface 32a. When the pipe 12 is covered with a plurality of piping covers 22, the connection cover 29 covers the boundary between the piping covers 22. By fixing the connection cover 29 to the wall surface 32a in this state, the piping cover 22 is attached to the wall surface 32a.

[0017] <Attachment structure of pipe 12 to wall surface 32a> As shown in Fig. 2, the pipe 12 is attached to the wall surface 32a by being held by a saddle 33 fixed to the wall surface 32a. The pipe 12 may have different diameters depending on the usage situation. As shown in Figs. 2 to 4, the saddle 33 is capable of holding pipes 12 of different diameters. The pipe 12 and the saddle 33 are covered by the piping cover 22 described above.

[0018] As shown in FIG. 5, the saddle 33 includes a fixed piece 34, a positioning piece 35, and a movable piece 36. The fixed piece 34 is in the shape of a rectangular plate. The fixed piece 34 is formed with a hole 37 for fixing the saddle 33 to the wall surface 32a with a screw or the like, and a recess 40 used for positioning the saddle 33 with respect to the wall surface 32a. The positioning piece 35 protrudes from one side of the fixed piece 34 in the direction opposite to the wall surface 32a. The positioning piece 35 is used for positioning the piping cover 22 on the wall surface 32a. The movable piece 36 protrudes from one side of the fixed piece 34 opposite to the movable piece 36 side in the direction opposite to the wall surface 32a. The saddle 33 is capable of holding the pipe 12 between the positioning piece 35 and the movable piece 36.

[0019] The hole 37 and the recess 40 are used when fixing the saddle 33 to the wall surface 32a. The hole 37 is located closer to the movable piece 36 than the center of the fixed piece 34. The recess 40 is formed on one of the four sides that form the outer edge of the fixed piece 34, other than the positioning piece 35 and the movable piece 36. The recess 40 is located on a straight line L1 that is perpendicular to the center line of the hole 37 and parallel to the positioning piece 35. A reference line is drawn on the wall surface 32a as a reference when fixing the saddle 33. Then, a screw is driven into the center of the hole 37 in the wall surface 32a with the center of the hole 37 and the center of the recess 40 of the saddle 33 aligned with the reference line. As a result, the saddle 33 is fixed to the wall surface 32a in the state where it is positioned as described above.

[0020] A rib 38 is formed at the intersection of the positioning piece 35 and the fixed piece 34 in the saddle 33. The rib 38 is for reinforcing the saddle 33 so that the relative position of the positioning piece 35 with respect to the fixed piece 34 does not change through deformation. A slit 39 is formed at the intersection of the movable piece 36 and the fixed piece 34 in the saddle 33. The slit 39 is for reducing the rigidity of the saddle 33 so that the relative position of the movable piece 36 with respect to the fixed piece 34 can change through deformation. Therefore, by changing the relative position of the movable piece 36 with respect to the fixed piece 34 through the above deformation, it becomes possible for the saddle 33 to hold pipes 12 of different diameters as shown in Figures 2 to 4.

[0021] The piping cover 22 includes a main body 41 curved to open toward the wall surface 32a, and a flange 42 protruding outward in the width direction from the opening of the main body 41. The main body 41 and the flange 42 extend along the wall surface 32a in the same direction as the pipe 12. The flange 42 is formed with a protrusion 43 protruding toward the wall surface 32a from the tip in the protruding direction relative to the main body 41, and a protrusion 44 protruding from the flange 42 toward the wall surface 32a at a position closer to the main body 41 than the protrusion 43.

[0022] The portion on the outer surface of the piping cover 22 where the main body 41 and the flange 42 intersect forms a curved surface 45 with a predetermined radius of curvature. In addition, the portion on the outer surface of the piping cover 22 corresponding to the base end of the protrusion 43 of the flange 42 forms a curved surface 46 with a predetermined radius of curvature.

[0023] When covering the pipe 12, the piping cover 22 is applied to the wall surface 32a so as to accommodate the pipe 12 and the saddle 33 inside the main body 41. At this time, the inner surface of the main body 41 is applied to the positioning piece 35 of the saddle 33, thereby positioning the piping cover 22 relative to the wall surface 32a, more specifically, positioning the piping cover 22 relative to the reference line drawn on the wall surface 32a. Thereafter, the piping cover 22 is attached to the wall surface 32a as described above.

[0024] Next, the pipe joint covers 24 to 28, 30, and 31 and the connection cover 29 of the piping system 11 will be described in detail individually. <Pipe joint cover 24> As shown in Figs. 6 to 11, the pipe joint cover 24 has a main body 47. As shown in Fig. 12, an accommodation space 48 for accommodating the pipe joint 14a (14) shown in Fig. 1 is formed inside the main body 47. The main body 47 has a connection part 49 formed toward the piping cover 22 that covers the pipe 12 connected to the pipe joint 14a. The connection part 49 has a connection port 50 that is connected to the outer surface of the piping cover 22. The portion of the connection part 49 near the connection port 50 is the portion of the main body 47 near the connection port 50. The connection part 49 has an appearance that becomes wider in the direction along the wall surface 32a from the connection port 50 toward the inner depth of the accommodation space 48.

[0025] The main body 47 is formed so that the storage space 48 is open toward the wall surface 32a and the connection port 50 is also open. A flange 51 is formed at the opening of the main body 47 that opens toward the wall surface 32a and protrudes outward from the opening. The flange 51 extends along the opening of the main body 47. The flange 51 is included in the main body 47 and the connection portion 49. The flange 51 is formed with a plurality of holes 53 for fixing the pipe joint cover 24 to the wall surface 32a with screws or the like. The plurality of holes 53 are formed at predetermined intervals in the direction in which the flange 51 extends.

[0026] A boss 54 is formed on the surface of the flange 51 facing the wall surface 32a, in other words, on the inner surface of the pipe fitting cover 24, so as to surround the opening of the hole 53. The boss 54 protrudes from the inner surface. The flange 51 is formed with a protrusion 52 that protrudes from the tip in the protruding direction relative to the main body 47 toward the wall surface 32a. The protrusion 52 extends along the tip of the flange 51 in the same direction as the extension of the flange 51. The protruding height of the protrusion 52 is set to be equal to the protruding height of the boss 54.

[0027] The pipe fitting cover 24 covers the pipe fitting 14a so as to accommodate the pipe fitting 14a in the accommodation space 48. At this time, the portion of the pipe fitting cover 24 corresponding to the connection port 50 covers the outer surface of the longitudinal end of the piping cover 22. Thick portions 56, 57 that are thicker than other portions of the pipe fitting cover 24 are formed at the portion of the inner surface of the pipe fitting cover 24 that corresponds to the connection port 50, the portion where the main body 47 and the flange 51 intersect, and the portion that corresponds to the base end of the protrusion 52.

[0028] The thick portion 56 comes into surface contact with the portion on the outer surface of the piping cover 22 where the main body 41 and the flange 42 intersect, i.e., the curved surface 45. This surface contact can be realized because the surface of the thick portion 56 that faces the curved surface 45 is curved with the same radius of curvature as the curved surface 45. The thick portion 57 comes into surface contact with the portion on the outer surface of the piping cover 22 that corresponds to the base end of the protrusion 43, i.e., the curved surface 46. This surface contact can be realized because the surface of the thick portion 57 that faces the curved surface 46 is curved with the same radius of curvature as the curved surface 46.

[0029] When the pipe joint cover 24 covers the outer surface of the longitudinal end of the piping cover 22, the portion corresponding to the connection port 50 comes into contact with the outer surface as shown in FIG. 13. At this time, the longitudinal end of the piping cover 22 is inserted into the connection port 50. A rib 55 is formed on the inner side of the connection portion 49, more specifically, on the inner side of the protrusion 52 of the flange 42, at a position corresponding to the outer surface of the protrusion 43 of the flange 42 in the piping cover 22, so as to abut the outer surface. The rib 55 protrudes from the flange 42 in the same direction as the protrusion 52. The rib 55 extends in the longitudinal direction of the piping cover 22 on both sides of the width direction of the connection port 50. The rib 55 is connected to the protrusion 52 at the end on the connection port 50 side at an acute angle, so that it extends from the connection port 50 in the direction toward the pipe joint 14a.

[0030] The rib 55 determines the shape of the vicinity of the connection port 50 in the accommodation space 48. In detail, the accommodation space 48 has a shape that extends from the connection port 50 toward the pipe fitting 14a side, which is the innermost side of the accommodation space 48, with a constant width, unlike the appearance of the main body portion 47 (connection portion 49). Such a shape is realized by the rib 55. The rib 55 abuts against the outer surface of the protrusion 43 of the flange 42 in the piping cover 22 along the direction from the connection port 50 toward the pipe fitting 14a side. As a result, the inclination of the main body portion 47 of the pipe fitting cover 24 relative to the piping cover 22 is restricted by the rib 55. In other words, the pipe fitting cover 24 is prevented from easily moving in a direction rotating about the connection port 50 relative to the piping cover 22. Therefore, when the pipe fitting cover 24 is fixed to the wall surface 32a with a screw or the like, it is not difficult to determine the fixing position.

[0031] FIG. 14 shows another example of the rib 55 in the pipe joint cover 24. The rib 55 does not necessarily need to be connected to the protrusion 52 of the flange 42 as shown in FIG. 13, and may not be connected to the protrusion 52 as shown in FIG. 14. In this case, if the insertion amount of the longitudinal end of the piping cover 22 into the connection port 50 is reduced, the end of the piping cover 22 can be prevented from abutting against the rib 55. If the end of the piping cover 22 is not abutted against the rib 55, the pipe joint cover 24 can be freely tilted to a certain extent relative to the piping cover 22. As a result, the degree of freedom of the fixing position of the pipe joint cover 24 to the wall surface 32a is increased. By adjusting the insertion amount of the end of the piping cover 22 into the connection port 50 in this way, the rib 55 can be abutted against the piping cover 22 or not abutted against it depending on the situation, and the pipe joint cover 24 can be used in a variety of ways.

[0032] In addition, in the pipe joint cover 24 shown in Figs. 13 and 14, the rib 55 may be removed as necessary. <Pipe joint cover 25> As shown in Figures 15 to 20, the pipe joint cover 25 has a main body 58. As shown in Figure 21, an accommodation space 59 for accommodating the pipe joint 14b (14) shown in Figure 1 is formed inside the main body 58. As the pipe joint 14b, one having a smaller body size than the pipe joint 14a is used.

[0033] The main body portion 58 of the pipe fitting cover 25 is provided with a connection portion 60, a connection port 61, a flange 62, a protrusion 63, a hole 64, a boss 65, and thick portions 66, 67 which correspond to the connection portion 49, connection port 50, flange 51, protrusion 52, hole 53, boss 54, and thick portions 56, 57 in the main body portion 47 of the pipe fitting cover 24 described above.

[0034] The pipe joint cover 25 covers the pipe joint 14b, which is smaller in size than the pipe joint 14a covered by the pipe joint cover 24. When fixing the pipe joint cover 25 to the wall surface 32a with screws or the like, if the longitudinal end of the piping cover 22 is inserted too far inside the pipe joint cover 25, the flange 42 of the piping cover 22 may overlap with the hole 64 of the pipe joint cover 25. However, since the boss 65 is formed around the hole 64, when the above-mentioned overlap occurs, the boss 65 overlaps with the flange 42 of the piping cover 22 by an amount that causes the pipe joint cover 25 to float above the wall surface 32a.

[0035] By identifying this floating, the worker can know that the longitudinal end of the piping cover 22 is inserted too far inside the pipe fitting cover 25, and can redo the work of fixing the pipe fitting cover 25 to the wall surface 32a with screws or the like. If the pipe fitting cover 25 is fixed to the wall surface 32a with screws or the like while the flange 42 of the piping cover 22 overlaps with the hole 64 and boss 65 of the pipe fitting cover 25, the fixation may not be performed properly. However, the occurrence of such poor fixation can be prevented by redoing the work.

[0036] <Pipe joint cover 26> As shown in Figures 22 to 27, the pipe joint cover 26 has a main body 68. As shown in Figure 28, an accommodation space 69 for accommodating the pipe joint 15 shown in Figure 1 is formed inside the main body 68. As the pipe joint 15, one having a shape bent at a predetermined angle, such as 45°, is used.

[0037] The main body 68 of the pipe joint cover 26 is bent at a predetermined angle to correspond to the pipe joint 15. The main body 68 is provided with a connection portion 70, a connection port 71, a flange 72, a projection 73, a hole 74, a boss 75, and thick portions 76 and 77 which correspond to the connection portion 49, the connection port 50, the flange 51, the projection 52, the hole 53, the boss 54, and the thick portions 56 and 57 in the main body 47 of the pipe joint cover 24 described above.

[0038] <Pipe joint cover 27> As shown in Figures 29 to 34, the pipe joint cover 27 has a main body 78. As shown in Figure 35, an accommodation space 79 for accommodating the pipe joint 16 shown in Figure 1 is formed inside the main body 78. As the pipe joint 16, one having a shape to which the faucet 21 can be connected is used.

[0039] The main body 78 of the pipe fitting cover 27 is cylindrical. As shown in Figures 29 and 30, the main body 78 is formed with a hole 80 for connecting the faucet 21 to the pipe fitting 16 accommodated in the accommodation space 79. The main body 78 is provided with a connection portion 81, a connection port 82, a flange 83, a projection 84, a hole 85, a boss 86, and thick portions 87 and 88 which correspond to the connection portion 49, connection port 50, flange 51, projection 52, hole 53, boss 54, and thick portions 56 and 57 in the main body 47 of the pipe fitting cover 24 described above.

[0040] 36 and 37 show another example of the pipe joint cover 27. In this pipe joint cover 27, the height in the center line direction of the main body 78 is made lower than that shown in Figures 29 to 35, and the diameter of the hole 80 is made smaller than that shown in Figures 29 to 35.

[0041] <Pipe joint cover 28> As shown in Figures 38 and 39, the pipe joint cover 28 has a main body 89. Inside the main body 89, an accommodation space 90 is formed for accommodating the pipe joint 17 shown in Figure 1. As the pipe joint 17, one having a shape extending linearly is used. The pipe joint cover 28 can also be used to cover a tee joint.

[0042] The main body 89 of the pipe joint cover 28 has a shape that extends linearly in correspondence with the pipe joint 17. The main body 89 is provided with a connection portion 91, a connection port 92, a flange 93, a projection 94, a hole 95, a boss 96, and thick portions 97, 98 that correspond to the connection portion 49, connection port 50, flange 51, projection 52, hole 53, boss 54, and thick portions 56, 57 in the main body 47 of the pipe joint cover 24 described above.

[0043] <Connection cover 29> 40 and 41, the connection cover 29 has a main body 99. Inside the main body 99, an accommodation space 100 is formed for accommodating the ends of the piping covers 22 shown in FIG. 1, more specifically, the boundaries of the piping covers 22 when the pipes 12 are covered with the piping covers 22.

[0044] The main body 99 of the connection cover 29 has a shape extending linearly, and is shorter than the main body 99 of the pipe joint cover 28 shown in Figures 38 and 39. The main body 99 of the connection cover 29 is provided with a connection portion 101, a connection port 102, a flange 103, a projection 104, a hole 105, and thick portions 107, 108 which correspond to the connection portion 49, connection port 50, flange 51, projection 52, hole 53, and thick portions 56, 57 in the main body 47 of the pipe joint cover 24 described above.

[0045] <Pipe joint cover 30> As shown in Figures 42 and 43, the pipe joint cover 30 has a main body 109. Inside the main body 109, an accommodation space 110 for accommodating the pipe joint 19 shown in Figure 1 is formed. As the pipe joint 19, one having an elongated T-shape is used.

[0046] The main body 109 of the pipe joint cover 30 has an elongated T-shape corresponding to the pipe joint 19. The main body 109 is provided with a connection portion 111, a connection port 112, a flange 113, a projection 114, a hole 115, a boss 116, and thick portions 117, 118 which correspond to the connection portion 49, connection port 50, flange 51, protrusion 52, hole 53, boss 54, and thick portions 56, 57 in the main body 47 of the pipe joint cover 24 described above.

[0047] <Pipe joint cover 31> As shown in Figures 44 and 45, the pipe joint cover 31 has a main body 119. Inside the main body 119, an accommodation space 120 for accommodating the pipe joint 20 shown in Figure 1 is formed. As the pipe joint 20, one having a shape bent at 90 degrees is used.

[0048] The main body 119 of the pipe joint cover 31 is bent at 90° to correspond to the pipe joint 20. The main body 119 is provided with a connection portion 121, a connection port 122, a flange 123, a projection 124, a hole 125, a boss 126, and thick portions 127 and 128 which correspond to the connection portion 49, connection port 50, flange 51, projection 52, hole 53, boss 54, and thick portions 56 and 57 in the main body 47 of the pipe joint cover 24 described above.

[0049] Next, the function and effect of the pipe joint cover of this embodiment will be described. (1) On the inside of the connection portion 49 of the pipe joint cover 24, more specifically, on the inside of the protrusion 52 of the flange 42, ribs 55 are formed on both sides in the width direction of the connection port 50, extending in a direction from the connection port 50 toward the pipe joint 14a. The ribs 55 determine the shape of the vicinity of the connection port 50 in the accommodation space 48. More specifically, the accommodation space 48 has a shape that extends at a constant width from the connection port 50 toward the pipe joint 14a, which is the innermost side of the accommodation space 48, unlike the appearance of the main body portion 47 (connection portion 49). This shape is realized by the ribs 55.

[0050] When the portion of the pipe joint cover 24 corresponding to the connection port 50 covers the outer surface of the longitudinal end of the piping cover 22, the piping cover 22 is inserted into the connection port 50. At this time, the rib 55 abuts against the outer surface of the protrusion 43 of the flange 42 of the piping cover 22 in the direction from the connection port 50 toward the pipe joint 14a. This restricts the inclination of the main body 47 of the pipe joint cover 24 relative to the piping cover 22. In other words, the rib 55 at this time suppresses the pipe joint cover 24 from easily moving in a direction rotating around the connection port 50 relative to the piping cover 22.

[0051] This makes it possible to prevent the pipe joint cover 24 from being easily tilted with respect to the piping cover 22, that is, from being easily moved in a direction rotating around the connection port 50. Therefore, when fixing the pipe joint cover 24 to the wall surface 32a with screws or the like, it is not difficult to determine the fixing position. In addition, since the pipe joint cover 24 is not fixed to the wall surface 32a in a tilted state with respect to the piping cover 22, the aesthetic appearance of the pipe joint cover 24 when viewed from the outside is improved.

[0052] (2) In the pipe joint cover 24, the ribs 55 are formed on the flat flange 51, so that the ribs 55 can be easily formed. (3) The rib 55 extends in a direction from the connection port 50 toward the pipe fitting 14a by connecting the rib 55 to the protrusion 43 of the flange 51 at an acute angle at the end on the connection port 50 side. As described above, the rigidity of the flange 51 can be increased by connecting the rib 55 to the protrusion 43 of the flange 51 at an acute angle.

[0053] (4) Thickened portions 56, 57 are formed on the inner surface of the pipe fitting cover 24, i.e., on the surface of the flange 51 on the wall surface 32a side, at a location corresponding to the connection port 50, where the main body 47 and the flange 51 intersect, and at a location corresponding to the base end of the protrusion 52. The thickened portions 56, 57 are thicker than other locations on the pipe fitting cover 24. The thickened portion 56 is in surface contact with the location on the outer surface of the piping cover 22 shown in Figs. 2 to 4 where the main body 41 and the flange 42 intersect, i.e., the curved surface 45. The thickened portion 57 is in surface contact with the location on the outer surface of the piping cover 22 corresponding to the base end of the protrusion 43, i.e., the curved surface 46.

[0054] Therefore, the pipe joint cover 24 can be fixed to the wall surface 32a while being in stable contact with the piping cover 22. In addition, since it is not necessary to thicken the entire portion of the pipe joint cover 24 where the main body 47 and the flange 51 intersect, and the entire portion corresponding to the base end of the protrusion 52, the manufacturing cost of the pipe joint cover 24 can be kept low.

[0055] As described above, no gap is generated between the thick portions 56, 57 and the curved surfaces 45, 46 by making surface contact therebetween. Therefore, such a gap is not visible from the outside, and the aesthetic appearance of the pipe joint cover 24 can be improved.

[0056] (5) When fixing the pipe fitting cover 25 to the wall surface 32a with screws or the like, if the longitudinal end of the piping cover 22 is inserted too far inside the pipe fitting cover 25, the flange 42 of the piping cover 22 may overlap the hole 64 of the pipe fitting cover 25. However, since the boss 65 is formed on the surface of the flange 62 of the pipe fitting cover 25 on the wall surface 32a side so as to surround the hole 64, the worker can know that the longitudinal end of the piping cover 22 is inserted too far inside the pipe fitting cover 25. More specifically, when the above-mentioned overlap occurs, the pipe fitting cover 25 is raised from the wall surface 32a by the amount that the boss 65 overlaps with the flange 42 of the piping cover 22. By identifying this floating, the worker can know that the longitudinal end of the piping cover 22 is inserted too far inside the pipe fitting cover 25, and can redo the work of fixing the pipe fitting cover 25 to the wall surface 32a with screws or the like.

[0057] (6) The pipe joint covers 25 to 28, 30, 31 and the connection cover 29 also have thick portions corresponding to the thick portions 56, 57 of the pipe joint cover 24, and therefore the same effect as in (4) above can be obtained.

[0058] (7) The pipe joint covers 26 to 28, 30, and 31 also have bosses corresponding to the boss 54 of the pipe joint cover 24, and therefore the same effect as in (5) above can be obtained. The above embodiment can be modified, for example, as follows: The above embodiment and the following modified examples can be combined with each other to the extent that no technical contradiction occurs.

[0059] The thick portions 56, 57 do not necessarily have to be formed on the pipe joint cover 24. The boss 54 does not necessarily have to be formed on the pipe joint cover 24 . [Explanation of symbols]
