Description

  The present invention relates to a piping device for piping a pipe material.

  Conventionally, for example, to use electricity outdoors, the terminal of a cable that is buried in the ground from an outlet or switchboard installed in a building or the like or branched out from an electric wire is fixed at a specific location. In addition, wiring and piping devices for outdoor installation that protect it are used. Patent Document 1 proposes a power supply pole as a piping device.

  The piping device of Patent Document 1 includes a pipe-shaped pole body (1) erected on the ground, and a waterproof outlet (6) as a power feeding portion whose insertion portion is exposed to the outside of the pole body (1). An electric wire (C) for energizing the waterproof outlet (6) passes through the inside of the pole body (1). In this piping device, wiring of the electric wire (C) from the power source to the waterproof outlet (6) is performed as follows. With the switchboard on the side wall of the building as a power source, a pipe (14) for interpolating and protecting the electric wire C is stretched over the ground. Then, the pipe (14) is inserted into the pole body (1) from the pipe insertion part (2) of the pole (1) and is connected to the partition wall (15) via the connector (16). The electric wire (C) inserted into the pipe (14) passes upward from the partition wall (15) and is electrically connected to the waterproof outlet (6).

Japanese Patent Laid-Open No. 6-86433

  However, in the invention of Patent Document 1, in order to pipe the pipe (14) for inserting the electric wire (C) into the pole (1), from the upper end opening of the pole body (1) or the outlet mounting hole, It is necessary to insert a tool and connect the end of the pipe (14) to the partition wall (15) with the connector (16) inside the pole body (1). In particular, many pipes (tube materials) that are generally used have flexibility, and the end of the pipe (14) hangs down by its own weight in the pole body (1). It takes a lot of time to search for the position of the end of the pipe (14) by inserting a hand through the opening or the like. Furthermore, regardless of whether the pipe (14) is flexible, while supporting or gripping the pipe (14) with one hand, maintaining its end in a position connected to the connector (16), Since the end of the pipe (14) must be connected to the connector (16), one hand is always closed in the pipe work, and work efficiency and workability are significantly reduced. In other words, the pipe connection work from these openings or mounting holes is performed in a closed (narrow) space in the pole (1), and the work is performed by groping in a place where the worker cannot reach.

The vertical and horizontal dimensions of the pipe material support member 120 and the positions of the support holes are designed so that the center substantially coincides with the center. That is, the pipe material support member of the present invention is designed to have a predetermined shape and size so as to correspond to the shape and size of the hollow cylinder and the pipe connector.

  Further, in the plan view of the tube material support member 120, a concave portion 125 formed in a step shape is formed on the outer surface thereof. While the contact portion 123 and the maintaining portion 124 are in close contact with the inner surface of the side wall 113 of the hollow cylinder 110, a predetermined space is formed between the hollow cylinder side wall 113 and the tube material support member 120 by the recess 125. The Through this space, a ground wire G (see FIG. 9) or the like can be wired outside the pipe material C.

  In addition, although the pipe material support member 120 of this embodiment is integrally molded with hard synthetic resin, this invention is not limited to this, The material and manufacturing method can be selected arbitrarily. For example, the maintenance part 124 of the tube material support member 120 may be configured as a metal leaf spring, and each part may be configured separately. Furthermore, although the support part of the tube material support member 120 of this embodiment is the support holes 121 and 122 drilled in the tube material support member main body, this invention is not limited to this. For example, the support portion may be a C-shaped or U-shaped support member instead of these through holes, and these may be assembled to the tube material support member main body as a divided body.

  A substantially cylindrical receiving port 135 having a retaining mechanism 138 capable of gripping and fixing the pipe material C is provided at the lower end of the piping box 134. Then, adjacent to the receiving port 135, a second receiving port 135 a for inserting (another) pipe material is formed in the bottom surface of the box portion 134. This receiving port 135a is used, for example, when wiring two systems of electric wires as in the modified example of FIG. 11, and inserts another pipe material arranged in parallel with the pipe material C so as to be piped.

  The pipe material C used in the present embodiment is a flexible corrugated pipe material, and as shown in FIG. 5 (d), the receiving port 135 has a retaining mechanism 138 that holds the bellows valley portion of the pipe material C. have. And the latching claw 138a protrudes inward of the receiving port 135 by operating the said retaining mechanism 138 by rotating it around an axis. As will be described later, when the tube material C is inserted into the receiving port 135 in this operating state, the locking claw 138a protruding inside the receiving port 135 is pushed by the entering tube material C and bent outward to allow further entry. At the same time, the pipe C can be fitted into the bellows valley of the pipe C and the pipe C can be locked in the longitudinal direction. Alternatively, after the tube material C is inserted into the receiving port 135 in the released state, the retaining mechanism 138 is rotated so that the locking claws 138a are fitted into the bellows valleys of the tube material C. Can be locked. On the other hand, when the retaining mechanism 138 is rotated in the reverse direction from the above operating state, the locking claw 138a is retracted, the lock is released, and the tube material C can move in the longitudinal direction in the receiving port 135. That is, in the retaining mechanism 138 of the present embodiment, the pipe material C is allowed to enter the receiving port 135 in both the operation and release states.

  In the present embodiment, one retaining port 135 is provided with a retaining mechanism, and the other retaining port 135a is not provided with a retaining mechanism. However, the present invention is not limited to this, and a retaining mechanism can be arbitrarily provided. Furthermore, it goes without saying that the receiving port and the pipe material of the present invention are not limited to the above-described embodiment, and the user can arbitrarily select the form. For example, the pipe connection member (coupling) is provided at the end of the pipe material, and the connection member corresponding to the pipe connection member is also provided at the receiving port, so that both can be connected. Alternatively, the tube material may be a rubber or metal tube having no bellows shape. In this case, the inner surface of the receiving port is in pressure contact with the outer surface of the tube material, so that the tube material can be connected to the receiving port so as not to come off.

  Moreover, although the instrument installation body 130 of this embodiment is obtained by shape | molding hard resin, this invention is not limited to this. For example, a metal plate or the like can be employed, and the material and manufacturing method can be arbitrarily selected.

  FIG. 6 is an overall perspective view of the wiring box 140 as the second pipe connector of the present invention. The wiring box 140 is a casing having an open front side surface, and includes a main body 141 that can be wired inside, and an upper receiving port 142 and a lower receiving port 143 formed on the upper and lower surfaces of the main body 141, respectively. As shown in FIG. 7B, the wiring box 140 has a rectangular shape when viewed from the front, and has a width and a length that substantially match the shape of the installation hole 116 of the hollow cylinder 110.

  As shown in FIGS. 7A and 7C, the upper receiving port 142 and the lower receiving port 143 formed on the upper surface and the lower surface of the main body 141 of the wiring box 140 are notched in a U shape in plan view. Thin engagement pieces 142a and 143a are formed at the notch edges, which are arranged in the valleys of the bellows tube. The upper receiving port 142 and the lower receiving port 143 have a width corresponding to the outer diameter of the tube material C (valley tube valley) so that the bellows-shaped tube material C can be slid sideways and inserted. In addition, the U-shape is opened on the rear side surface of the main body 141. That is, when the pipe material C is fitted into the receiving ports 142 and 143, the engaging pieces 142a and 143a sandwich the valley of the pipe material C, and the engaging pieces 142a and 143a are fitted into the bellows valley of the pipe material C. The pipe material C is connected to the receptacles 142 and 143.

  In the wiring box 140, an electric wire extending downward from the pipe member C1 connected to the upper receiving port 142 and an electric wire extending upward from the pipe member C2 connected to the lower receiving port 143 are connected, and these are energized or insulated. A switch S (see FIG. 8) is attached. However, the present invention is not limited to this, and an outlet or the like may be attached instead of the switch.

  In addition, although the wiring box 140 of this embodiment is obtained by shape | molding hard synthetic resin etc., this invention is not limited to this, The material and manufacturing method can be selected arbitrarily.

  FIG. 8 is an overall perspective view of the piping device 10 disposed on the ground. A hollow cylinder 110 to which the pipe material C is piped is erected on the ground, and an instrument mounting body 130 is attached to the upper end 111 side of the hollow cylinder 110. The lid portion 132 of the fixture installation body 130 closes the opening 114 at the upper end 111 of the hollow cylindrical body, and the wiring fixture fixing portion 131 and the skirt portion 133 are arranged across the edges 115a, 115b, and 115c of the through hole 115. Yes. Further, the wiring device E is installed so as to cover the through hole 131a. That is, in the state in which the piping device 10 is arranged so that power can be supplied, the opening 114 and the through hole 115 are closed by the instrument mounting body 130, and the inside of the hollow cylinder 110 is not exposed in a state where rainwater or the like can enter. A switch S is attached to the wiring box 140 embedded in the side wall 113 of the hollow cylinder 110. By operating the switch S, power supply to the wiring device E can be turned on and off. Note that, instead of the switch S, an outlet may be installed so that two power sources can be used. In this case, as illustrated in FIG. 11, by connecting two pipe members to the receiving port 135 and the receiving port 135 a of the fixture installation body 130, for example, 200 V power is supplied on the top side of the piping device 10, and the piping device 10 Different voltage power supplies can be provided so that a 100V power supply is supplied on the side.

  FIG. 9A is an AA longitudinal sectional view of the piping device 10. As shown in FIG. 9A, the tube material support member 120 is disposed in the hollow cylinder 110 in the vicinity of the upper end of the tube material C. The tube material support member 120 is disposed substantially parallel to the horizontal direction (that is, the width direction of the hollow cylinder 110), and supports the tip of the tube material C so as to be directed in the vertical direction (longitudinal direction of the hollow cylinder 110). ing. Then, in a state where the tube material C is inserted into the support hole 121 of the tube material support member 120 and supported by the tube material support member 120 at a predetermined connection position, the tip thereof is connected to the receiving port 135 of the instrument mounting body 130. Yes.

  FIG. 9B shows a BB cross-sectional view of FIG. As shown in FIG. 9B, the contact surface 123 of the tube material support member 120 is in close contact with the inner surface of the rear side wall 113d of the hollow cylinder 110, and the support hole 135 is separated from the rear wall 113d by a predetermined distance. At this time, the center of the support hole 121 and the center of the receiving port 135 are disposed so as to substantially coincide with each other in the front-rear direction of the hollow cylinder 110. That is, the abutting surface 123 is brought into contact with the rear side wall 113d, and at the same time, the pipe material C and the connection hole 135 are aligned in the front-rear direction.

  Further, the left and right side maintenance portions 124 of the pipe material support member 120 are in contact with the left and right side walls 113b and 113c and are bent and deformed inward. The tube material support member 120 is maintained at a predetermined position in the hollow cylindrical body 110 by the elastic restoring force of these maintaining portions 124. And since the external shape of the pipe material support member 120 is formed left-right symmetrically, both the maintenance parts 124 bend and deform | transform by the same amount, and the position of the left-right direction of the support hole 121 is defined. At this time, the center of the support hole 121 and the center of the receiving port 135 are disposed so as to substantially coincide with each other in the left-right direction of the hollow cylinder 110. That is, the left and right maintenance portions 124 are brought into contact with the left and right side walls 113b and 113c, respectively, and at the same time, the tube material C and the connection hole 135 are aligned in the left and right direction.

  That is, the abutment surface 123 and the maintaining portion 124 of the tube material support member 120 abut on the side walls 113b, c, d of the hollow cylinder 110 from three directions, thereby along the radial direction of the tube material C (or the hollow cylinder 110). In the horizontal plane, the center position of the support hole 121 (or 122) and the center position of the receiving port 135 (or receiving port 135a) are arranged so as to be substantially aligned with the longitudinal direction of the hollow cylinder 110. Yes. Then, the tube material C supported by the tube material support member 120 in the vicinity of the tip is guided into the receiving port 135 of the instrument installation body 130.

  Moreover, as shown to Fig.9 (a), the earth wire G by which the one end was buried in the ground is connected to the fixing hole 119a of the upper end 111 of the hollow cylinder 110. FIG. As shown in FIG. 9B, the ground wire G passes through the recess 125 of the tube material support member 120, and the tip of the ground wire G extends from the hole 116 of the hollow cylindrical lower end 112 and is grounded.

  In this piping device 10, the through hole 115 and the through hole 131 a (and the front opening of the box portion 134) communicate with each other, and externally (from the wiring device E) through the through hole 115 and the through hole 131 a. Electric power can be supplied. Since the wiring fixture fixing portion 131 is disposed along the cut-out edge 115b of the through hole 115, the wiring fixture fixing portion 131 is located inward of the (outermost) outer surface of the front side wall 113a of the hollow cylinder 110. ing. Accordingly, the wiring device E attached to the surface of the wiring device fixing portion 131 is arranged so as not to protrude outward from the front side wall 113a. The instrument mounting body 130 is stably locked to the hollow cylindrical body 110 by sandwiching an edge portion close to the lower end of the through hole 115 of the front side wall 113a between the downward portion of the skirt 133 and the closing portion 133a. .

  In the present embodiment, the thin wiring device E is used so that the wiring device E does not protrude outward from the front side wall 113a. However, the present invention is not limited to this, and the wiring device can be arbitrarily selected. It is. Further, in this embodiment, the wiring apparatus E employs a waterproof outlet with a hood provided on the top, but the present invention is not limited to this, for example, a thin outlet without a hood or other standards. An outlet can be adopted. That is, the user can employ the wiring device E as appropriate according to the application.

  Next, with reference to FIGS. 10A to 10C, a method for constructing the piping device 10 by attaching the instrument mounting body 130 to the hollow cylindrical body 110 and connecting the pipe material C to the receiving port 135 will be described. To do.

  First, as shown in FIG. 10A, the tube material support member 120 is moved from the opening 114 (upward) or the through hole 115 (side) of the hollow tube 110 into the hollow tube 110, and the tube material support member 120 is moved. The tip of the tube material C is inserted into the support hole 121. Then, when the tube material support member 120 is pushed rearward inside the hollow cylinder 110 with the tube material C inserted through the support hole 121 and supported, the contact surface 123 of the tube material support member 120 becomes the rear side wall of the hollow cylinder 110. It abuts on 113d. At this time, since the maintenance part 124 of the tube material support member 120 is in pressure contact with the inner surfaces of the left and right side walls 113b and c of the hollow cylinder 110, the tube material support member 120 is maintained in that position. And the pipe material C is supported by the pipe material support member 120 from the state bent at the front-end | tip of Fig.10 (a) to the state linearly extended along a perpendicular direction like FIG.10 (b). At this time, the distal end (connected portion) of the pipe material C is supported and maintained at a predetermined connection position. Furthermore, if necessary, the vertical alignment of the pipe material C is performed based on the instruction line 118. For example, the tip of the tube material C can be disposed in the vicinity of the indicator line 118 by cutting the tip of the tube material C or sliding the tube material C in the longitudinal direction. That is, in the state of FIG. 10B, the connected portion of the tube material C supported by the support hole 121 of the tube material support member 120 is aligned in the horizontal direction and the moving direction (axis L direction). In the maintenance state of the present embodiment, the tube material support member 120 can move up and down in the hollow cylinder 110 when a predetermined force is applied, but by using a stronger leaf spring, The tube material support member 120 may be arranged so as not to move.

  Next, as shown in FIG. 10 (b), the box part 134 and the receiving port 135 located on the back surface of the instrument mounting body 130 are inserted into the hollow cylinder 110 through the opening 114, and the flange 136 side surface and the left and right side walls 113b, The tool mounting body 130 is slid downward relative to the hollow cylinder 110 while bringing the outer surface of c into contact with the back surface of the wiring tool fixing portion 131 and the edge 115 b of the through hole 115. At this time, the center of the support hole 121 and the tube material C of the tube material support member 120 and the center of the receiving port 135 of the instrument installation body 130 are arranged on the same axis L. That is, the connecting direction of the receiving port 135 and the moving direction of the receiving port 135 to the hollow cylinder 110 are aligned in parallel along the axis L. Then, when the instrument mounting body 130 is brought close to the pipe material C along the axis L so that the instrument mounting body 130 cuts through the through-hole 115, the tip (connected portion) of the pipe material C is guided into the receiving port 135. Both are connected. At the same time, the lid 132 is engaged with the edge of the opening 114 to close the opening 114, and the skirt 133 is disposed on the edges 115 a and 115 c in the width direction of the through-hole 115. The receiving port 135 is tapered so that the inner diameter of the receiving port 135 is wider than the outer diameter of the tube material C. Therefore, even if the distal end of the tube material C and the center of the receiving port 135 are slightly deviated from the axis L, When the two come into contact with each other, the tip of the tube material C slides with respect to the inner surface of the receiving port 135, and the tube material C is guided to be inserted into the receiving port 135.

  And when connecting the front-end | tip of the pipe material C and the receiving port 135, the retaining mechanism 138 of the receiving port 135 can be used. That is, when the tubular material C is inserted into the receiving port 135 in a state where the retaining mechanism 138 of the receiving port 135 is operated, the entered tube material C is locked by the locking claws 138a of the retaining mechanism 138, and the tubular material C is received by the receiving port 135. It is connected indefinitely. However, if the receiving port 135 is accessible from the outside, the retaining mechanism 138 may be operated after connection. Alternatively, if the tubular material C does not move in the longitudinal direction with the other end portion of the tubular material C fixed, the tubular material C can be installed at the time of installation of the piping device 10 without operating the retaining mechanism 138. It is connected in the receptacle 135 so as not to be detached. That is, in a state where the piping device 10 is installed, a situation in which the pipe material C is bent in the longitudinal direction and comes out of the receiving port 135 rarely occurs, so that the pipe material C is stably maintained in a state where it enters the receiving port 135. Is done. In addition, when the pipe material support member 120 is disposed in the vicinity of the upper end of the pipe material C, when the pipe material support member 120 comes into contact with the receiving port 135 so that the end of the pipe material C does not interfere with the receiving port 135, the pipe material C It is preferable that the pipe material supporting member 120 is configured to slide downward along the pipe material supporting member 120. Alternatively, if the pipe material C and the pipe material support member 120 are disposed so as not to move relative to each other, the pipe material support member is previously lowered from the upper end of the pipe material C by the amount of the connection allowance so as not to disturb the connection. It is preferable to arrange 120 with respect to the pipe material C.

  As shown in FIG. 10 (c), the instrument mounting body 130 is formed on the flange 136 in a state in which the opening 114 and the through hole 115 of the hollow cylindrical body 110 are covered and the tube material C is connected to the receiving port 135. The fixing holes 137a and 137b are aligned with the fixing holes 119a and 119b formed in the side wall 113. The instrument mounting body 130 is fixed to the hollow cylinder 110 by screwing screws into the fixing holes 119 and 137. Furthermore, the electric wire which jumps out of the pipe material C and extends upward is connected to the wiring device E via the through hole 115 and the through hole 131a, and the wiring device E is inserted into the tubular material C while the electric wire device E is pushed into the through hole 131a. By fixing the wiring device fixing portion 131 with screws through the fixing holes 131b provided in the edge portion, the piping device 10 capable of supplying power can be constructed.

  In the above-described installation method of the present embodiment, the other end of the pipe material C is already fixed to the protective tube or the wiring source and the tip of the pipe material C cannot be pulled out. This is possible both in the case where the tube material C is not fixed and can be pulled out freely from the hollow cylinder 110. Because, by moving the tube support member 120 into the hollow cylinder 110 and supporting and maintaining the tube material C at a predetermined position by the tube support member 120, the instrument mounting body 130 is moved close to the tube material C. This is because the tip, which is a connected portion of the pipe material C, is guided into the receiving port 135 without gripping the pipe material C by hand. However, in the latter case, when connecting the pipe material C and the pipe connector 130, it is necessary to separately provide a means for regulating the movement of the pipe material C in the axial direction so that the pipe material C is not displaced in the axial direction.

  Hereinafter, the effect of the piping apparatus 10 of one Embodiment which concerns on this invention is demonstrated.

  According to the piping device 10 of the present embodiment, the abutment surface 123 and the maintenance portion 124 of the tube material support member 120 are abutted against the inner surface of the side wall 113 of the hollow cylinder 110 to facilitate positioning of the support holes 121 and 122. In addition, since the support holes 121 and 122 positioned in the hollow cylinder 110 can be maintained at a predetermined position by the leaf spring-shaped maintaining portion 124, the connected portion of the tube material C can be easily disposed at the predetermined connection position. Can be maintained. That is, the tube material support member 120 supports the tube material C so as to maintain the distal end (connected portion) of the tube material C at a predetermined connection position in the hollow cylindrical body 110, so that, for example, work is performed in a dark place. Even in this case, the operator can easily specify the position of the connected portion of the pipe material C by searching.

  Then, as described with reference to FIG. 10, the instrument mounting body 130 as a pipe connection body (other member) is brought close to the tip of the pipe material C in a state where the pipe material C is supported and maintained by the pipe material support member 120. As a result, the tip of the tube material C is guided into the receiving port 135 and the instrument mounting body 130 is attached to the hollow cylinder 110. That is, when attaching the instrument installation body 130 to the hollow cylinder 110, the tube material support member 120 is attached to the pipe material C at a predetermined connection position on the path (axis L) along which the receiving port 135 of the instrument installation body 130 moves. Arrange and maintain connections. That is, it is possible to eliminate the necessity for the operator to perform the connection work while holding either or both of the receiving port 135 and the tube material C so that the receiving port 135 and the connected portion of the tube material C are aligned with each other. In particular, when designing the power supply position of the power supply pole to be a high position, it is difficult to connect the tube material C to the instrument mounting body 130 in the hollow cylinder 110 after the hollow cylinder 110 is erected. However, in this embodiment, since the process of connecting the pipe material C to the receiving port 135 and the process of attaching the instrument mounting body 130 to the hollow cylinder 110 are common, the instrument mounting body 130 is moved closer to the pipe material C. The piping device 10 can be immediately constructed by one operation of making it occur. Therefore, according to the piping device 10 of the present embodiment, efficiency and ease in piping work can be improved.

  Further, as shown in FIG. 1, when shipping or transporting as a product a tube material C, a hollow cylinder 110, a tube material support member 120, a fixture installation body 130, and a wiring box 140 that are removably assembled together, the tube material C However, the tubular material C can be prevented from colliding with the inner surface of the side wall 113 of the hollow cylindrical body 110 by being violated inside the hollow cylindrical body 110. In particular, when the pipe material C is hard, such as metal, this effect is remarkable, and it is possible to suppress product damage and noise generation during transportation.

(Example 2)
The piping apparatus 10 shown in FIG. 11 is configured to pipe two pipe materials C and C ′. Furthermore, in the piping device 10 of the first embodiment, the wiring box 140 is embedded in the hollow cylinder 110 in advance, whereas in the piping device 10 of the second embodiment, the wiring box 140 is not embedded. That is, in the present embodiment, it will be described below that the function of the tube material support member of the present invention is similarly exhibited when the wiring box 140 is embedded in the hollow cylinder 110 from the side. In addition, since the process which attaches the instrument mounting body 130 to the hollow cylinder 110 and the pipe material C front-end | tip using the pipe material support member 120 arrange | positioned in the uppermost position is common in Example 1, description is abbreviate | omitted.

  As shown in FIG. 11, the tube material C is divided into two parts, an upper tube material C1 and a lower tube material C2, the lower end of the upper tube material C1 and the upper receiving port 142 of the wiring box 140 are connected, and the upper end of the lower tube material C2 And the lower receiving port 143 are connected to each other. Further, a plurality (three) of pipe material support members 120 are arranged near the upper end of the upper pipe material C1, near the lower end of the upper pipe material C1, and near the upper end of the lower pipe material C2. Each tubular material support member 120 supports and maintains the tubular materials C and C ′ at predetermined connection positions. Then, with the pipe material support member 120 supporting and maintaining the upper pipe material C1 and the lower pipe material C2 at predetermined connection positions, the piping box 140 is inserted into the installation hole 116 from the side of the hollow cylinder 110, The connected portions of the pipe materials C1 and C2 are connected to the receiving ports 142 and 143, respectively, and the piping box 140 is embedded in the installation hole 116 of the hollow cylinder 110.

  Next, the installation method of the piping box 140 will be described in more detail. In this method, two pipe material support members 120 arranged near the upper and lower sides of the installation hole 116 are used, and the uppermost tube material support member 120 is not particularly mentioned.

  First, one (upper) tube material support member 120 is disposed in the hollow cylindrical body 110 from the installation hole 116. Next, the lower end of the upper pipe material C <b> 1 is inserted into the support hole 121 of the pipe material support member 120. Then, in a state where the vicinity of the lower end of the upper tubular material C1 is supported by the tubular material support member 120, the contact surface 123 of the tubular material support member 120 is pushed into contact with the rear side wall 113d of the hollow cylindrical body 110, and the maintenance portion The tube material support member 120 is slid above the installation hole 116 so that 124 is brought into contact with the left and right side walls 113b, c, thereby positioning the support hole 121 (the connected portion of the tube material C1) in the width direction of the hollow cylinder 110. Do. Alternatively, the tubular support member 120 is disposed in the hollow tubular body 110 from the end (the opening 114 or the through hole 115) of the hollow tubular body 110, and the tubular material C1 is inserted into and supported by the support hole 121. The positions of the tube material support member 120 and the tube material C may be finely adjusted from the side of the tube (that is, from the installation hole 116). And the same operation | work is performed also about the other (lower side) pipe material support member 120, and the to-be-connected part vicinity of the upper end of the downward pipe material C2 is performed.

  Then, as shown in FIG. 12A, the center of the support hole 121 (that is, the connected portion of the upper tube material C1 and the lower tube material C2) of one and the other tube material support member 120 and the wiring embedded in the installation hole 116 The centers of the upper and lower receiving holes 142 and 143 of the box 140 are aligned on the axis M, and the wiring box 140 is moved closer to the pipes C1 and C2 in the radial direction thereof. As described above, since the configuration of the installation hole 116 and the outer shape of the wiring box 140 are configured to coincide with each other, when the wiring box 140 is inserted into the installation hole 116, the support hole 121 and the receiving ports 142 and 143 are naturally separated. Are aligned on axis M.

  As shown in FIG. 12B, when the wiring box 140 is inserted into the installation hole 116 and brought close to the pipes C1 and C1 along the axis M, the pipes C1 and C2 are placed at the open ends of the receiving ports 142 and 143, respectively. Led. And if the pipe material support member 120 is pushed in to the back, the engagement pieces 142a and 143a of the receptacles 142 and 143 will fit in the valley parts of the bellows pipe materials C1 and C2. Even if the positional relationship between the pipe materials C1 and C2 and the receiving ports 142 and 143 is slightly deviated from the axis M, the pipe materials C1 and C2 are bent and guided to the receiving ports 142 and 143.

  That is, in the second embodiment, the wiring box 140 is moved close to the tube material C so as to be fitted into the hollow cylinder 110 from the side, and at the same time, is supported at a predetermined connection position by the two tube material support members 120. The lower end (connected portion) of the upper tube material C1 and the upper end (connected portion) of the lower tube material C2 are guided into the upper receiving port 142 and the lower receiving port 143 of the wiring box 140. Therefore, by simply attaching the wiring box 140 to the installation hole 116 of the hollow cylinder 110, the connected portions of the pipe materials C1 and C2 can be quickly and easily connected to the receiving ports 142 and 143, respectively, and efficiency in piping work And ease can be improved. In this embodiment, the end portion of the pipe material is connected to the receiving port, but the receiving port of this embodiment is a type that can be engaged from the side of the tube material, so the position of the connected portion is other than the end portion. Can also be arbitrarily selected.

(Example 3)
Furthermore, as shown in FIG. 13, when the other end portion of the tube material C is not fixed and can be pulled out freely in the longitudinal direction, the tube material C is inserted into the support hole 121 of the tube material support member 120, and the tube material C The tube material support member 120 is arranged in the hollow cylinder 110 so that the center of the support hole 121 (and the connected portion of the tube material C) of the support member 120 and the center of the receiving port 135 are positioned on the same axis L. At this time, the tube material support member 120 holds the tube material C in the support hole 121 so as not to slide. Then, when the tubular material support member 120 is slid upward along the side wall 113 of the hollow cylindrical body 110 together with the tubular material C in a state where the tubular material C is gripped and moved close to the receiving port 135, The connecting portion is guided to the receiving port 135. That is, the abutting surface 123 and the maintaining portion 124 that functions as the abutting portion (hereinafter also referred to as the abutting portion 124 in the third embodiment) abut on the inner surface of the hollow cylinder 110, whereby the tube material C and the support member 120.

The form of the piping device of the present invention is not limited to the above embodiment. In the piping device 10 according to one embodiment, the hollow cylinder 110 has a square cylinder shape, but the present invention is not limited to this. For example, in the piping device 10A shown in FIG. 14A, the hollow cylinder 110A is formed in a cylindrical shape. A through hole 115A is formed by cutting out the side wall 113A of the hollow cylinder 110A in a plan view (circular) arc shape, and the through hole 115A and the opening 114A are continuous. In this instrument mounting body 130A, the lid portion 132A and the skirt portion 133A have an arc shape in plan view so as to correspond to the shape of the opening 114A and the plan view shape of the through hole 115A.

  Furthermore, as shown in FIG. 14B, the pipe material support member 120A is formed in a circular arc shape in plan view so that the outer surface thereof corresponds to the inner surface of the side wall 113 of the hollow cylinder 110A. The tube support member 120A is provided with support holes 121A and 122A through which the tube C is inserted, and a contact surface 123A is formed on the outer periphery thereof. Further, the contact surface 123A has a fine uneven surface, and when the contact surface 123A contacts the inner surface of the side wall 113A of the hollow cylinder 110A, a frictional force is generated to maintain the tube support member 120A in a predetermined position. Is possible. That is, the contact surface 123A also functions as the maintaining portion 124A. When the pipe support member 120A is disposed inside the hollow cylinder 110A, the pipe support member 120A is slid vertically downward (to resist the frictional force) from the opening 114A of the hollow cylinder 110A to a predetermined connection position. To place.

Furthermore, the maintenance part 124B protrudes from the both sides of the pipe material support member 120B. The maintenance part 124B is a plate spring of a type different from that of the maintenance part 124 of the first embodiment, and the tip thereof extends obliquely as a free end.

(Modification 3)
FIG. 15B shows a tube material support member 120C having a shape different from that of the above embodiment. In the pipe material support member 120C, a magnet is formed on the abutting surface 123B as the maintaining portion 124C. That is, when the hollow cylinder is a steel material, the support portion 124C can be attached to the side wall of the hollow cylinder by a magnetic force to maintain the support hole 124C of the tube material support member 120C at a predetermined connection position. Alternatively, instead of the magnet, the maintenance unit 124C can be a double-sided tape or the like. Furthermore, if the tube support member is processed with high precision so that the outer surface of the tube support portion and the inner surface of the hollow cylindrical body are in close contact with each other, even if a leaf spring or a magnet is not formed, the close contact surface A frictional force is generated, and the pipe support member can be maintained at a predetermined position by the frictional force.

  That is, any means that can be envisaged by those skilled in the art can be employed in the maintenance portion of the present invention as long as the tube material support member can be maintained at a predetermined position with respect to the hollow cylindrical body. Further, in the pipe material support member of the above-described embodiment, two support holes are formed as support portions, but it is also possible to form one or three or more support portions. Furthermore, in the present embodiment, the support portion is described as a support hole, but any means that can support the pipe material at a predetermined position may be used, and the concept is not limited to the support hole. For example, the support portion may be configured in a bowl shape so as to be supported by sandwiching the tube material C, or may be configured as a double-sided tape, a magnet, or the like to support the tube material C at a predetermined position. Moreover, the tube material support member of the present invention only needs to function so as to support and maintain the tube material, and the tube material support member integrally provided in the hollow cylinder other than the above-described embodiment and the non-detachable member are also the same. Needless to say, it is a concept included in
