Description

  The present invention relates to a concealed piping auxiliary system for assisting the realization of concealed piping.

  For example, in condominiums such as condominiums and rental apartments, there is a room space (hereinafter referred to as “inside room space”) that faces only other room spaces without facing the external environment such as balconies or shared corridors. There is. And when installing an air conditioner in the inside room space, in order to avoid piping members such as refrigerant pipes connecting indoor units and outdoor units from being exposed indoors, the piping members should be There is a case where a so-called concealment pipe disposed in a concealed state on the back of the ceiling or the wall is performed. In order to make such a concealed piping possible in the future, it is possible to install a straight tubular guide member on the back of the ceiling in advance when constructing a housing complex, for example, Japanese Patent Laid-Open No. 6-42778 (Patent Document 1). Is disclosed. In the technique of Patent Document 1, work spaces are provided on both sides of a guide member installed on the back of the ceiling, and work ports are provided in portions corresponding to the work spaces on the ceiling plate.

  However, providing a work opening large enough to allow the operator's upper body to enter not only requires a large installation work for the work opening, but is also not preferable in terms of the appearance of the room. In addition, it is generally not easy for an operator to insert the piping member into the guide member in a narrow working space by entering the upper body from the working port, and the workability when actually implementing the concealed piping is good. I can't say that.

JP-A-6-42778

  It is desired to realize a concealed piping auxiliary system that can improve the workability when concealing piping is performed without significantly impairing the appearance of the room.

The hidden piping auxiliary system according to the present invention is
A concealed piping auxiliary system that assists in arranging a piping member connecting an indoor unit and an outdoor unit of an air conditioner in a concealed state on a ceiling or wall of a building,
A straight tubular guide member installed along a ceiling plate or partition wall as a concealing member in the ceiling or the back of the wall,
A tubular joint member installed in an inclined shape so as to connect a through hole formed in the concealing member and through which the piping member is inserted, and one end of the guide member;
Is provided.

  According to this configuration, the joint member installed in an inclined shape connects the insertion-side end portion of the piping member inserted from the through hole formed in the ceiling plate or the partition wall (concealment member) to one end of the guide member. Induce. Alternatively, the joint member installed in an inclined shape guides the insertion side end of the piping member fed from the other end of the guide member to the through hole formed in the concealing member. Therefore, the worker can easily arrange the piping member on the back of the ceiling or the back of the wall through the inside of the guide member and the joint member while remaining in the indoor space. In addition, it is not necessary to provide a work opening large enough to allow the operator's upper body to enter as in the prior art, and it is only necessary to form a through hole large enough to allow the piping member to be inserted. Less likely to get worse. Therefore, by using the concealed piping auxiliary system having the above-described configuration, it is possible to improve the workability when implementing the concealed piping without significantly impairing the appearance of the room.

  Hereinafter, preferred embodiments of the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.

It is preferable to further include a first covering member that covers a distal end edge of the hole facing the distal inner surface.

When the insertion side end of the piping member fed from one end of the guide member is guided to the through hole of the concealing member by the joint member installed in an inclined shape, the insertion side end of the piping member is distant from the joint member. Moves in sliding contact with the inner surface of the distal side. In this case, when the distal inner surface of the joint member and the distal end edge of the through hole are opposed to each other with a step, for example, the indoor space side of the piping member is located at the position of the distal end edge. Smooth movement may be hindered. Alternatively, a portion of the concealing member in the vicinity of the distal end edge of the through hole may be partially damaged by rubbing against the insertion side end of the piping member or the outer surface of the piping member.
In this regard, according to the above configuration, since the first covering member covers the distal inner surface of the joint member and the distal end edge of the through hole, the joint member is taken out when the piping member is taken out to the indoor space side. The piping member can be smoothly moved regardless of the positional relationship between the distal inner surface of the through hole and the distal end edge of the through hole. Moreover, it can prevent that the site | part near the distal end edge of the through-hole in a concealing member is damaged.

  As one aspect, in the insertion state inserted in the opening end on the through hole side in the joint member, the proximal inner surface located on the concealing member side among the inner surfaces of the joint member and the through hole in the through hole It is preferable to further include a second covering member that covers the proximal end facing the proximal inner surface.

When the piping member inserted from the through hole of the concealing member is further fed out through the inside of the guide member, the proximal inner surface of the joint member and the proximal end edge of the through hole have a step, for example. When facing each other, the piping member may move in sliding contact with the proximal end edge of the through hole. In this case, there is a possibility that a portion of the concealing member near the proximal end edge of the through hole is rubbed with the outer surface of the piping member and partially damaged.
In this respect, according to the above configuration, the second covering member covers the proximal inner surface of the joint member and the proximal end edge of the through hole. Regardless of the positional relationship between the proximal inner surface of the joint member and the proximal end edge of the through hole, it is possible to prevent a portion of the concealing member near the proximal end edge of the through hole from being damaged. .

  As one aspect, in the interpolated state, the inner surface of the joint member covers the proximal inner surface located on the concealing member side and the proximal edge facing the proximal inner surface of the through hole. It is preferable that a second covering member is further provided, and the first covering member and the second covering member are integrally formed.

  According to this configuration, the through-hole in the concealing member can be formed at the time of construction only by inserting a single member integrally formed with the first covering member and the second covering member into the opening end on the through-hole side of the joint member. It is possible to prevent damage to the vicinity of the edge of the pipe and to facilitate the work of taking out the piping member to the indoor space side.

  As one aspect, it is preferable that the joint member has a smooth inner surface.

  According to this configuration, it is possible to smoothly guide the insertion side end portion of the piping member inserted from the through hole formed in the concealing member to one end of the guide member. Or the insertion side edge part of the piping member sent out from the other end of the guide member can be smoothly guided to the through hole formed in the concealing member.

When the concealment pipe auxiliary system 1 is installed in the ceiling space Sc as in the present embodiment, the ceiling plate 75 serves as a “concealment member” that conceals the concealment pipe auxiliary system 1 and the pipe member 83.

  As shown in FIGS. 3 and 4, the joint member 30 is formed in a tubular shape. The joint member 30 of the present embodiment has a split structure, and includes a pair of joint split bodies 31 configured to be freely engaged and disengaged. The pair of joint divided bodies 31 is formed by equally dividing the joint member 30 on the left and right sides, and has a mirror target shape. One joint divided body 31 is provided with an engaging portion 32 made of, for example, an engaging protrusion, and the other joint divided body 31 is provided with an engaged portion 33 made of, for example, an engaging hole portion. In a state where the corresponding engaging portions 32 are engaged with the engaged portions 33, the pair of joint divided bodies 31 are integrated to form a tubular joint member 30.

  The joint member 30 is installed in an inclined shape as a whole so as to connect a through hole 76 formed in the ceiling plate 75 and through which the piping member 83 is inserted, and one end of the guide member 20 (see FIG. 9). The joint member 30 includes a connection port portion 34 connected to the end portion of the guide member 20 and a joint main body portion 35 extending from the connection port portion 34. The connection port portion 34 is formed to have a slightly larger diameter than the guide member 20 and is fitted on the guide member 20. The connection port portion 34 is disposed so as to be approximately parallel to the ceiling plate 75 in a state of being externally fitted to the guide member 20. The joint body 35 is formed so as to extend in a direction intersecting the connection port 34.

The through hole 76 is also formed in an elliptical shape similar to the shape of the opening end Eo. The joint member 30 is disposed such that the opening end Eo thereof faces the end edge 77 of the through hole 76. In the present embodiment, a portion of the end edge 77 of the through-hole 76 that faces the proximal side inner surface 38p of the joint member 30 is referred to as a “proximal side edge 77p” and is formed on the distal side inner surface 38d of the joint member 30. The facing part is referred to as “distal edge 77d”. Of the end edge 77 of the through hole 76, a portion on the guide member 20 side in a direction parallel to the axis of the guide member 20 is the proximal end edge 77 p, and a portion on the side away from the guide member 20 is the distal side. This is the edge 77d (see FIGS. 9 and 11).

  As shown in FIG. 5, the concealed piping auxiliary system 1 of the present embodiment further includes a first covering member 40 </ b> A that is inserted into the opening end Eo of the joint member 30 on the through hole 76 side. Here, “inserted into the opening end Eo” means that the first covering member 40A is inserted into the joint member 30 at least partially from the opening end Eo side. Therefore, an aspect in which a part of the first covering member 40A (for example, a hook-like portion 48 described later) is exposed to the outside of the joint member 30 is also included in the concept of “inserted into the opening end Eo”. . The first covering member 40A is inserted into the opening end Eo on the through hole 76 side of the joint member 30 (hereinafter, simply referred to as “insertion state”), and is distal to the opening end Eo side of the joint member 30. The side inner surface 38d and the distal end edge 77d of the through hole 76 are covered (see FIG. 9).

  The hidden pipe auxiliary system 1 of the present embodiment further includes a second covering member 40B that is inserted into the opening end Eo on the through hole 76 side of the joint member 30 separately from the first covering member 40A. The meaning of “inserted into the open end Eo” is as described above. The second covering member 40B covers the proximal inner surface 38p on the opening end Eo side of the joint member 30 and the proximal end edge 77p of the through hole 76 in the inserted state (see FIG. 9). In the present embodiment, the first covering member 40A and the second covering member 40B are integrally formed. In other words, the hidden pipe auxiliary system 1 includes the covering member 40 configured as a single member that covers the inner surface 38 on the opening end Eo side of the joint member 30 and the end edge 77 of the through hole 76 in the inserted state. ing.

  The covering member 40 includes a deformed tubular covering main body 41 that is actually disposed inside the joint member 30 in an inserted state, and a hook-like portion 48 that extends in a hook shape from the lower end of the covering main body 41. The covering main body 41 includes an elliptical tubular annular wall 42 corresponding to the shape of the through hole 76, a first wall 44 that is divided into two branches from the annular wall 42 and extends toward the inner side of the joint member 30, and 2nd wall part 45 is included. The first wall portion 44 extends from the first portion 42A corresponding to the distal inner surface 38d of the joint member 30 in the annular wall portion 42 and the distal end edge 77d of the through hole 76, and the joint member 30 in the annular wall portion 42 has the first wall portion 44A. A second wall 45 extends from the second portion 42B corresponding to the proximal inner surface 38p and the proximal end edge 77p of the through hole 76. The first wall portion 44 and the second wall portion 45 extend in different directions, and extend in different directions from the annular wall portion 42. A pair of curved cutout portions 46 are formed in the boundary region between the first wall portion 44 and the second wall portion 45.

  The first wall portion 44 is disposed in parallel to the distal inner surface 38 d of the joint member 30. The first wall portion 44 is disposed so as to be in full contact with the distal inner surface 38d (see also FIG. 9). The first portion 42 </ b> A of the annular wall portion 42 is formed to be steeper than the first wall portion 44 so as to be separated from the distal inner surface 38 d as it is separated from the first wall portion 44. The second wall portion 45 is disposed in a state where the second wall portion 45 approaches the proximal inner surface 38p of the joint member 30 as the distance from the second portion 42B of the annular wall portion 42 increases, and the distal end portion abuts on the proximal inner surface 38p. The annular wall part 42, the first wall part 44, and the second wall part 45 constituting the covering main body part 41 have a smooth inner surface. That is, the inner surface of the covering main body 41 is formed as a smooth surface without having irregularities. Further, the annular wall part 42, the first wall part 44, and the second wall part 45 constituting the covering main body part 41 are formed so as to be smoothly continuous with each other.

  The bowl-shaped part 48 is formed in a flat plate shape. The bowl-shaped portion 48 is formed in a perfect circle shape having a larger diameter than the maximum diameter of the through hole 76 formed in the ceiling plate 75. The bowl-shaped portion 48 is fixed to the ceiling plate 75 from the indoor space side so as to cover the through hole 76. The hook-shaped portion 48 is formed with a fixing hole 49 through which a fixing means such as a screw is inserted. The covering member 40 uses a fixing means in a state where the covering main body portion 41 is inserted into the opening end Eo on the through hole 76 side of the joint member 30 and the flange portion 48 is applied to the indoor side surface of the ceiling plate 75. And fixed to the ceiling plate 75. In a boundary region between the covering main body 41 (annular wall portion 42) and the flange-shaped portion 48, a pair of locked portions 43 made of, for example, slit-shaped holes are formed so as to face each other.

  In the present embodiment, the first covering member 40 </ b> A is configured by the first wall portion 44, the first portion 42 </ b> A of the annular wall portion 42, and the portions corresponding to these in the hook-shaped portion 48. The second covering member 40 </ b> B is configured by the second wall portion 45, the second portion 42 </ b> B of the annular wall portion 42, and portions corresponding to these in the hook-shaped portion 48.

  The concealed piping auxiliary system 1 of this embodiment further includes a lid member 50 that is attached to the bowl-shaped portion 48 of the covering member 40 and closes the through hole 76. As shown in FIG. 6, the lid member 50 is formed in a flat plate shape as a whole.

The standing height of the peripheral wall portion 52 is set to be approximately the same as the thickness of the bowl-shaped portion 48. Further, the lid member 50 includes a pair of locking portions 53 made of, for example, locking claws or the like that protrude from the lid main body portion 51. The pair of locking portions 53 are formed in the central region of the lid main body portion 51 so as to face each other. As shown in FIG. 7, the lid member 50 is attached to the covering member 40 from the indoor space side in a state where the locking portion 53 is locked to the locked portion 43 of the covering member 40. The lid member 50 is configured to be detachable from the covering member 40. For example, when the concealment pipe auxiliary system 1 is not used, the cover member 50 can block the opening end Eo of the joint member 30 on the through hole 76 side, and the cover member 50 can be removed during construction to implement the concealment pipe.

  Hereinafter, the construction procedure when carrying out concealment piping using the concealment piping auxiliary system 1 of the present embodiment will be described step by step. In addition, although it does not mention in particular regarding the indoor unit 81 and the outdoor unit 82 of the air conditioner 8, it shall install according to a conventional method.

  First, the cover member 50 is removed at both ends of the concealed piping auxiliary system 1, and the opening ends Eo on the through hole 76 side of the respective joint members 30 are exposed to the indoor space. Further, as shown in FIG. 8, a cap-shaped mounting member 60 is mounted on the insertion side end of the piping member 83. The mounting member 60 can be formed using the same resin material as that of each component constituting the concealed piping auxiliary system 1. The mounting member 60 is formed so as to become gradually thinner toward the tip end side and the tip end portion is rounded. The mounting member 60 has a smooth outer surface. That is, the outer surface of the mounting member 60 is formed as a smooth surface without having irregularities.

  Next, as shown in FIG. 9, the insertion-side end portion of the piping member 83 with the mounting member 60 mounted is inserted into the joint member 30 through the insertion-side through hole 76. At this time, the insertion-side end portion of the piping member 83 inserted from the through hole 76 is guided to one end of the guide member 20 by the joint member 30 installed in an inclined manner with respect to the ceiling plate 75. That is, the insertion-side end portion (mounting member 60) of the piping member 83 moves in sliding contact with the distal inner surface 38d of the joint member 30, and is guided to one end of the guide member 20 along the distal inner surface 38d. The Since both the distal inner surface 38d and the outer surface of the mounting member 60 are formed as smooth surfaces and the frictional resistance between them is small, the piping member 83 can be inserted smoothly.

  When the piping member 83 is guided to the guide member 20 and further inserted into the guide member 20, the piping member 83 may be in a state of being close to the proximal end edge 77p side of the through hole 76 as shown in FIG. is there. Even in this case, in this embodiment, the covering member 40 (particularly the second covering member 40B) is configured to connect the proximal inner surface 38p on the opening end Eo side of the joint member 30 and the proximal end edge 77p of the through hole 76. Since it coat | covers, the outer surface of the piping member 83 does not rub against the proximal side edge 77p directly. Therefore, when the piping member 83 is sent out, it is possible to prevent a portion of the ceiling plate 75 near the proximal end edge 77p of the through hole 76 from being damaged.

  When the piping member 83 is further inserted further, as shown in FIG. 11, the insertion side end portion (mounting member 60) of the piping member 83 extends from the other end of the guide member 20 to the inside of the joint member 30 on the extraction side. enter in. The insertion side end of the pipe member 83 to be sent out is guided to the through-hole 76 on the take-out side by the joint member 30 installed in an inclined manner with respect to the ceiling plate 75. That is, the insertion side end portion of the piping member 83 also moves in sliding contact with the distal inner surface 38d of the joint member 30 here, and is guided to the extraction side through hole 76 along the distal inner surface 38d. When the piping member 83 is further sent out, the insertion side end of the piping member 83 reaches the position of the tip of the first wall portion 44 of the covering member 40. At this time, the first wall portion 44 is disposed so as to be in full contact with the distal inner surface 38d, and the mounting member 60 is formed so that the tip portion is rounded. The insertion-side end portion easily climbs over a step corresponding to the thickness of the first wall portion 44. The insertion side end of the piping member 83 is further pushed out while sliding on the inner surfaces of the first wall portion 44 and the first portion 42A of the annular wall portion 42. Since both the inner surface of the covering main body 41 and the outer surface of the mounting member 60 are formed as smooth surfaces and the frictional resistance between them is small, the work of taking out the piping member 83 can be performed smoothly.

  The insertion side end of the piping member 83 advances toward the distal end edge 77d of the through hole 76 along the distal inner surface 38d of the joint member 30. Even in this case, in the present embodiment, the covering member 40 (particularly the first covering member 40A) is configured to connect the distal inner surface 38d on the opening end Eo side of the joint member 30 and the distal end edge 77d of the through hole 76. Since it is covered, the insertion side end and the outer surface of the piping member 83 do not directly rub against the distal end edge 77d (see FIG. 12). Therefore, when the piping member 83 is taken out, it is possible to prevent a portion of the ceiling plate 75 near the distal end edge 77d of the through hole 76 from being damaged.

  Thus, since the joint member 30 is provided on both the insertion side and the extraction side of the piping member 83 and the insertion and removal of the piping member 83 are appropriately guided, the operator can remain in the indoor space and The piping member 83 can be easily disposed in the back space Sc. In addition, for example, it is not necessary to provide a work opening large enough for the operator's upper body to enter, and it is only necessary to form the through-hole 76 large enough to allow the piping member 83 to be inserted with some margin. Appearance is less likely to deteriorate. Therefore, by using the concealed pipe auxiliary system 1 of the present embodiment, it is possible to improve the workability when the concealed pipe is carried out without significantly impairing the appearance of the room. In general, joint work by a plurality of workers is required for the execution of the concealment pipe, whereas the concealment pipe auxiliary system 1 of the present embodiment enables construction by only one worker. It was confirmed.

  Thereafter, as shown in FIG. 13, the piping member 83 taken out from the through hole 76 on the take-out side is sent out to the balcony BL through the through sleeve 94 fixed so as to penetrate the outer wall 72C. The piping member 83 is disposed downward along the outer wall 72 </ b> C, and the piping member 83 is connected to the outdoor unit 82 of the air conditioner 8. Finally, the piping member 83 exposed on the corner of the living room LDK and the balcony BL is covered with the piping cover 92. The pipe cover 92 can be configured by appropriately combining, for example, a straight pipe type cover 92A, an elbow type cover 92B, a cap type cover 92C, and the like according to the shape of the arrangement path of the pipe member 83.
