As shown in FIGS. 4 and 5, the fluid pipe joint 120 is a so-called faucet elbow made of a hollow cylinder having an L shape.

  The fluid pipe joint 120 has a first opening end 121 at one end and a second opening end 122 that opens in a direction orthogonal to the first opening end 121 at the other end. In the fluid pipe joint 120, a cylindrical body extending in the opening direction of the first opening end 121 is formed at least longer than the wall thickness so as to be able to penetrate the wall hole H. The outer periphery of the cylinder near the first opening end 121 is provided with a male screw portion 121a in which a plurality of screw threads are formed in a spiral shape. On the other hand, a female screw part 121b is provided on the inner periphery of the cylinder in the vicinity of the first opening end 121. The female screw portion 121b can be screwed into the screwing portion 112 of the attachment body 111, and can be screwed with a male screw of a connecting member such as a general water faucet or pipe. The second open end 122 is formed so that a fluid pipe P having both rigidity and flexibility can be connected. As shown in FIG. 5B, the second opening end 122 includes a press-fit portion 122a and a pressure-bonding ring 122b having a diameter larger than the inner diameter of the fluid pipe P. And in order to connect the fluid pipe P to the 2nd opening end 122, the internal diameter of the fluid pipe P is expanded with the existing jig | tool, the press-fit part 122a is inserted in the enlarged diameter part of the fluid pipe P, and the fluid pipe P The crimp ring 122b may be press-fitted into the press-fit portion 122a from above. The fluid pipe P is composed of a cross-linked polyethylene pipe, a polybuden pipe, or the like and has a predetermined rigidity, but can be arbitrarily bent along the piping path.

  Further, a disc-shaped flange portion 123 projecting in the radial direction is provided at the proximal end of the male thread portion 121a of the fluid pipe joint 120. This flange part 123 consists of a ring body screwed to the base end of the external thread part 121a (it has a thread part in an inner periphery). However, the flange portion 123 may be integrally formed with the fluid pipe joint 120. Furthermore, the fluid pipe joint 120 includes a first water stop ring 124 that is disposed in close contact between the plane of the flange portion 123 and the back surface of the wall material W. The first water stop ring 124 is a flat ring-shaped packing, and can be formed of a soft synthetic resin, rubber, or the like. As will be described later, in addition to the water stop function, the first water stop ring 124 exhibits a function of suppressing co-rotation of the fluid pipe joint 120 at the time of fixing.

  Further, the fixture 130 of the present arrangement device 100 includes a fixing ring 131, a sliding ring 132, and a second water stop ring 133. The fixing ring 131 includes a screw portion 131a provided on the inner periphery and a pair of holes 131b provided on a plane. The screw portion 131a of the fixing ring 131 can be screwed with the male screw portion 121a and has a minimum inner diameter L2 (equal to the minimum outer diameter of the male screw portion 121a). Further, the inner diameters of the sliding ring 132 and the second water stop ring 133 are larger than the minimum inner diameter L2 of the fixing ring 131 and smaller than the maximum outer diameter of the male thread portion 121b of the fluid fitting 120. The outer diameter L1 of the flange 113 of the attachment body 111 is determined to be smaller than the inner diameter L2 of the fixing ring 131. In other words, the arrangement device 100 is configured such that the attachment body 111 and the string-like body 117 can pass through the hollows of the fixing ring 131, the sliding ring 132, and the second water stop ring 133.

  In addition, although the fluid pipe joint 120 of this embodiment consists of metal faucet elbows, the fluid pipe joint of this invention is not limited to this. For example, the fluid pipe joint may be an I-shaped faucet nipple or a T-shaped faucet cheese as long as the fluid pipe joint has a shape that can be disposed through the wall hole. Or you may shape | mold a fluid pipe joint with a synthetic resin. That is, those skilled in the art can arbitrarily select the shape and material of the fluid pipe joint.

  6 and 7 are a perspective view and a sectional view of the arrangement structure 10 of the fluid pipe joint 120 constructed by the arrangement device 100 of the present embodiment. In this arrangement structure 10, a fluid pipe joint 120, which is a faucet elbow, is arranged in a circular wall hole H drilled in a side wall (wall material W) of a unit bus that stands vertically.

  As shown in FIGS. 6 and 7, in this arrangement structure 10, the tubular body on the first opening end 121 side of the fluid pipe joint 120 passes through the wall hole H drilled in the wall material W, and the first opening end 121 protrudes from the wall surface. Then, the fixing ring 131 is screwed onto the male threaded portion 121a of the fluid pipe joint 120, and the peripheral edge of the wall hole H is clamped (or clamped) by the flange 123 and the fixing ring 131, whereby the fluid pipe joint 120 is It is fixed to the wall material W. At this time, the screw part 131a of the fixing ring 131 is firmly screwed into the male screw part 121a, whereby the fixing ring 131 presses the sliding ring 132 and the second water stop ring 133 against the wall surface. Thereby, the 2nd water stop ring 133 adheres and press-contacts to the wall surface of the wall surface side, and the back surface of the sliding ring 132, and seals between the wall surface space and the wall hole H in the water stop state. At the same time, the first water stop ring 124 is in close contact with and pressed against the wall surface on the wall back side and the surface of the flange portion 123, and seals between the wall back space and the wall hole H in a water stop state. This sealing prevents water from flowing into the wall hole H and the wall back space when the wall surface space is filled with water. However, the water stop ring may be omitted in applications and environments where it is not necessary to consider the inflow of liquid or the like.

  In the wall surface space of the arrangement structure 10, an arbitrary connection member is attached to the first opening end 121 of the fluid pipe joint 120 fixed by the fixture 130. For example, the connecting member is not limited to the following, but can be selected from a faucet having a male screw that can be screwed to the female screw part 121b of the fluid pipe joint 120, a joint, a pipe material, and the like. On the other hand, in the wall space of the arrangement structure 10, the fluid pipe P extending in the vertical direction is connected to the second opening end 122 of the fluid pipe joint 120. Here, the lower end of the fluid pipe P is expanded, and the press-fit portion 122a of the second opening end 122 is inserted into the pipe. A pressure-bonding ring 122b fitted from the outside of the fluid pipe P presses the fluid pipe P against the press-fit portion 122a. That is, the fluid pipe P is press-fitted into the second opening end 122 in a water-stopped state. The upper end of the fluid pipe P is connected upstream of the piping system (not shown). In the arrangement structure 10 of the present embodiment, one fluid pipe joint 120 is arranged on the wall material W, but a plurality of fluid pipe joints 120 are arranged on the wall as in the arrangement apparatus of Patent Document 1. You may arrange in parallel with material W.

  8 and 9 are a perspective view and a cross-sectional view of the arrangement structure 10 'of the fluid pipe joint 120 constructed by the arrangement device 100 of the present embodiment. In the arrangement structure 10 ′, unlike the arrangement structure 10, the attachment body 111 of the arrangement jig 110 is attached to the first opening end 121 of the fluid pipe joint 120. At this time, the threaded portion 112 of the attachment body 111 is almost completely screwed into the female threaded portion 121 b of the fluid pipe joint 120, and the O-ring-shaped water stop portion 115 is fitted with the flange portion 113 and the second opening end 122. Between the inner edges (tips of the female screw portion 122b) and press-contact the two. That is, in the arrangement structure 10 ′, since the attachment body 111 functions as a stop cock, water is injected from the upstream of the piping system to the first opening end 121 of the fluid pipe joint 120 to perform a water pressure test. It is possible to implement. In particular, the attachment body 111 having the threaded portion 112 and the water stop portion 115 has a simple and robust structure, and the attachment body 111 can stop the first opening end 121 more reliably. In other words, if this attachment body 111 is screwed to the first opening end 121, a water pressure test is performed under more severe conditions (exceeding the water pressure limit of the water faucet) before attaching the connecting member such as a water faucet. Is possible. Further, by maintaining the arrangement structure 10 ′ before attaching the connecting member, the attachment body 111 protects the threaded portion during the preliminary piping or the preceding piping, and further the inside of the fluid pipe coupling 120. It functions to prevent foreign substances such as dust from entering the tub.

  With reference to FIG.10 and FIG.11, the method to arrange | position the fluid pipe joint 120 to the wall hole H with the arrangement | positioning structure 100 of one Embodiment of this invention is demonstrated.

  First, as shown in FIG. 10 (a), the attachment body 111 is screwed to the female thread portion 121b of the fluid pipe joint 120 in a wide space outside the wall (for example, a wall surface space or a space above the wall material). The attachment portion 111 is screwed into the first opening end 121 of the fluid pipe joint 120 almost completely. Simultaneously with or before and after this step, the press-fit portion 122a of the fluid pipe joint 120 is inserted into the fluid pipe P whose diameter is expanded at the lower end. The pressure ring 122b (the inner diameter of the pressure ring 122b is larger than the standard diameter of the fluid pipe P) is arranged around the fluid pipe P in the press-fit portion 122a in the state where the fluid pipe P is inserted. By forcibly pushing down (small), the fluid pipe P is pressed into the second opening end 122 in a water-stopped state. Note that the upper end of the fluid pipe P may be connected upstream of the piping system at this point, or may be connected in any other process.

  Next, the attachment body 111 in a state where the string-like body 117 is suspended and the fluid pipe joint 120 integrated with the fluid pipe P extending in the vertical direction are pushed into the space behind the wall. The fluid pipe joint 120 is pushed toward the wall hole H while holding the fluid pipe P in the space outside the wall. In this way, the arrangement jig 110 (the attachment body 111 and the string-like body 117), the fluid pipe joint 120, and the fluid pipe P (a part or all of them) are arranged on the back of the wall. At this time, the position of the first opening end 121 of the fluid pipe joint 120 is separated from the wall hole H in the vertical direction and / or plane direction of the wall material W, and the string-like body 117 of the attachment body 111 is the wall hole. Hanging near H.

  Next, as shown in FIG. 10 (b), the magnetic traction tool 140 (which can be interpreted as a part of the arrangement device 100) is directed to the wall surface of the wall material W, and the suspended string-like body 117 is free. The end (the magnetized portion 118) is detected and attracted from the wall surface by magnetism (see virtual line). Then, the string-like body 117 is guided to the wall hole H by moving it to the wall hole H in a state where the magnetized portion 118 is magnetically attached to the magnetic traction tool 140 via the wall material W, and can be easily moved to the front side of the wall. It can be pulled out. The magnetic traction tool 140 is configured to be able to emit sufficiently strong lines of magnetic force so that the magnetically attached part 118 made of a magnetic material can be drawn across the wall material W having a predetermined thickness. The magnetic traction tool 140 may be a permanent magnet type or an electromagnet type. Alternatively, as long as the magnetized portion 118 and the magnetic traction tool 140 can be relatively magnetized, the magnetic traction tool 140 may be a magnetic metal instead of a magnet. Alternatively, if the string-like body 117 is in a position where it is caught by a finger or a tool, it is possible to insert the finger or tool and pull it out from the wall hole H to the wall front side without using a magnetic force.

  Subsequently, the string-like body 117 (or the magnetized portion 118) with the free end pulled out on the front side of the wall is gripped and pulled to the front side of the wall, whereby the fluid pipe joint 120 together with the attachment body 111 and the fluid pipe P on the back of the wall. Is forcibly pulled to guide the first opening end 121 connected to the attachment body 111 to the wall hole H. Then, the fluid pipe joint 120 is pulled by the string-like body 117 until the first opening end 121 of the fluid pipe joint 120 (near the tip of the male thread 121a) and the attachment body 111 project from the wall hole H to the wall front side. Then, the fluid pipe joint 120 is moved to the position where the wall hole H is disposed.

  Next, after passing the free end (magnetic attachment part 118) of the string-like body 117 through the hollow of each ring (fixing ring 131, sliding ring 132, and second water stop ring 133) of the fixture 130, the attachment body The fixing tool 130 is attached to the first opening end 121 protruding to the front side of the wall so that the flange portion 113 of the 111 passes through the hollow of each ring of the fixing tool 130. At this time, the second water stop ring 133, the sliding ring 132, and the fixing ring 131 are arranged in this order from the wall material W side. Then, the threaded portion 131 a on the inner periphery of the fixing ring 131 is screwed into the male threaded portion 121 a of the fluid pipe joint 120 while selectively pulling the string-like body 117 toward the wall front side. By screwing the fixing ring 131 to the first opening end 121 while pulling the string-like body 117, the fluid pipe joint 120 can be prevented from falling to the back side of the wall, and the operation can be performed more stably. However, the operation of pulling the string-like body 117 is not essential for this step.

  Then, by inserting a jig such as a faucet wrench into the pair of holes 131b of the fixing ring 131 and rotating it, the fixing ring 131 can be strongly fastened to the male screw portion 121a. At this time, since the sliding ring 132 interposed between the fixing ring 131 and the second water stop ring 133 reduces the rotational frictional resistance of the fixing ring 131, the fixing ring 131 smoothly rotates on the sliding ring 132. The fixing ring 131 can be screwed more firmly to the male screw portion 121a. At the same time, the first water stop ring 124 presses against the flange portion 123 and the wall surface on the wall behind the wall to generate a high frictional force, so that the fluid pipe joint 120 rotates together when the fixing ring 131 is screwed. Is suppressed. As a result, in a good water stop state in which the first water stop ring 124 is pressed against the wall surface of the wall and the second water stop ring 133 is pressed against the wall surface of the wall, the fluid fitting 120 is fixed to the wall material W by the fixture 130. Fixed.

  Further, as an optional step, after fixing the fluid pipe joint 120 to the wall material W with the fixture 130, the attachment body 111 of the placement jig 110 is screwed to the first opening end 121 of the fluid pipe joint 120. As it is (form of arrangement | positioning structure 10 '), it can inject water from the upstream of a piping system to the 1st opening end 121, and can implement the hydraulic test of a piping system. As above-mentioned, since the attachment body 111 functions as a water stop cock, a water pressure test can be implemented on the water pressure conditions higher than the conditions after attaching a connection member. In this water pressure test, if water leakage is found, the location is identified and repaired.

  Subsequently, as shown in FIG. 11A, the attachment body 111 screwed to the female thread portion 121 b of the fluid pipe joint 120 is screwed in the disengagement direction and removed from the first opening end 121. Finally, as shown in FIG. 11B, the arrangement structure 10 can be constructed by connecting the connection member Q to the first opening end 121. The connecting member Q is composed of a water supply port member (whose cross-sectional structure is not shown in detail) in which a decorative cover and a faucet are integrated, but this is merely an example, and the connecting member Q is It is not limited to.

  Hereinafter, the effect in the arrangement | positioning apparatus 100 (the arrangement | positioning jig | tool 110 and the arrangement | positioning method) of one Embodiment which concerns on this invention is demonstrated.

  In the disposing apparatus 100 and the disposing jig 110 according to one embodiment, the string member 117 is pulled from the wall surface in a state where the attachment body 111 of the disposing jig 110 is coupled to the fluid pipe joint 120. The fluid pipe joint 120 can be pulled together with the adherend 111 and guided toward the wall hole H. That is, the first threaded end 112 of the fluid pipe joint 120 is guided to the wall hole H by operating the string-like body 117 of the placement jig 110 from the wall surface, and the male thread portion of the fluid pipe joint 120 disposed on the back of the wall. 121a can be easily protruded from the wall hole H. Furthermore, since the fluid pipe joint 120 can be guided toward the wall hole H in a state where the fluid pipe P is connected to the second open end 122 of the fluid pipe joint 120, the fluid pipe is previously placed before being placed on the back of the wall. P can be connected to the second open end 122. In other words, it is possible to eliminate the necessity of performing the work of connecting the fluid pipe P to the fluid pipe joint 120 in the back space, and to perform the work in a wider work space. Therefore, the disposing device 100 of the present embodiment reduces the adverse effects caused by the space behind the wall, and allows the fluid pipe joint 120 to be disposed quickly and easily by the wall hole H.

  In the method of disposing the fluid pipe joint 120 in the wall hole H according to one embodiment, the placement jig 110 is attached to the first opening end 121 of the fluid pipe joint 120 before the fluid pipe joint 120 is placed on the back of the wall. The attached body 111 is attached, and the fluid pipe P is connected to the second open end 122 of the fluid pipe joint 120. Since these operations are performed in a wider working space outside the wall before the fluid fitting 120 is pushed into the wall, the operation can be performed easily and quickly. Then, the string-like body 117 of the arrangement jig 110 is operated from the wall surface to guide the first opening end 121 of the fluid pipe joint 120 to which the fluid pipe P is connected to the wall hole H, and is arranged on the back of the wall. Further, the male thread portion 121a of the fluid pipe joint 120 can be easily protruded from the wall hole H to the wall surface. Next, in this method, before the disposing jig 110 is detached from the fluid pipe joint 120, the fluid pipe joint 120 is fixed with the fixture 130. That is, the fixing tool 130 is provided so that the fluid pipe joint 120 is held in the wall hole H while selectively pulling the string-like body 117 of the arrangement jig 110 when the fixing is performed, and the fluid pipe joint 120 is not dropped from the wall hole H. Thus, the fluid pipe joint 120 can be securely fixed to the wall material W. Alternatively, even when the fluid pipe joint 120 is unexpectedly dropped on the back of the wall at the time of fixing, the attachment body 111 is connected to the fluid pipe joint 120. Therefore, by pulling the string-like body 117 again, the fluid pipe joint 120 can be easily returned to the position immediately before fixing. Furthermore, by maintaining the state where the attachment body 111 is attached to the first opening end 121 until the connecting member Q is connected to the first opening end 121, the first opening end 121 can be connected to the preliminary piping or the preceding piping. It is possible to protect and prevent foreign matter from entering the fluid pipe joint 120.

(Modification)
In the present embodiment, the first opening end 121 and the attachment body 111 are coupled by screwing, but the present invention is not limited to this. That is, other coupling means may be employed as long as at least the string-like body can be pulled along with the attachment body and guided toward the wall hole. For example, the first opening end and the attachment body may be coupled by fitting. In this case, compared to the above embodiment, the water stop effect by the attachment body cannot be expected, but the attachment body can be attached to the first opening end with a simpler operation. Alternatively, a hook-shaped locking portion is provided on the attachment body, and the locking portion is hooked on a locked portion provided on the arrangement body, and the arrangement body is pulled together with the attachment body by the string-like body. Good.

  The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes as long as they belong to the technical scope of the present invention.
