The five supports 16 are arranged at equal intervals. For example, when a flexible pipe having a nominal diameter 50 rigidity is used for the drain pipe 20, the interval between the adjacent support tools 16 is set to 0.6 m or more. The five support tools 16 are first, second,..., Fifth support tools 16a, 16b,.

  The support 16 has a base 30 as shown in FIGS. 2 and 3A. The base 30 has a rectangular plate shape and is disposed horizontally. Screw holes 32 are formed at both ends of the base 30, and screws 34 are fitted into the screw holes 32. Two vertical support portions 36 extend from the upper surface of the base 30 in the vertical direction.

  The vertical support portion 36 has a rectangular plate shape, and the two vertical support portions 36 are provided in parallel with a gap therebetween. This interval is set larger than the outer diameter of the drain pipe 20, and the drain pipe 20 passes between the two vertical support portions 36. In addition, the cushioning material 38 is attached to the inner surface of the vertical support portion 36, that is, the surface on the side where the two vertical support portions 36 face each other. The buffer material 38 is formed of sponge or rubber. As a result, even if the drainage flows through the drainage pipe 20 and the drainage pipe 20 shakes and the drainage pipe 20 hits the vertical support portion 36, the generation of the collision sound and the breakage of the drainage pipe 20 are suppressed by the buffer material 38.

  Further, a long hole 40 is formed at the center of the vertical support portion 36 in the width direction, the long hole 40 extends in the longitudinal direction of the vertical support portion 36, and a scale 42 is attached to the side of the long hole 40. The scale 42 represents the height from the base portion 30 and is marked on the outer surfaces of the two vertical support portions 36.

  A lateral support portion 44 is provided at a right angle to the longitudinal support portion 36, and the lateral support portion 44 extends in the horizontal direction. The lateral support portion 44 includes a rectangular plate-like portion 46 and a bolt portion 48. The horizontal length of the plate-like portion 46 is set to be smaller than the interval between the two vertical support portions 36, and the plate-like portion 46 is disposed between the two vertical support portions 36. A cylindrical communication portion 50 is disposed at the center of the plate-like portion 46, and a communication hole 52 is provided at the center of the communication portion 50. The communication hole 52 is formed so as to penetrate the plate-like portion 46, and the long member 18 is passed through the communication hole 52.

  As shown in FIGS. 1 (A) and 1 (B), two support tools 16 arranged at both ends among the plurality of support tools 16 arranged, that is, the first support tool 16a and the fifth support tool. A tool that can be fixed to the communication portion 50 is used as the tool 16e, and the long member 18 is fixed to the support tool 16 at the fixable communication portion.

Then, the plate-like portion 46 is sandwiched between the body 152 and the nut 154, the wire chuck 150 is attached to the lateral support portion 44, and then the long member 18 is inserted into the communication hole 52. The scale member 18 can be fixed. Further, if the wire chuck 150 is further provided with a caulking portion (not shown) and the caulking portion is caulked through the long member 18, the long member 18 can be firmly fixed. Details of the wire chuck 150 are described in Japanese Patent Application Laid-Open No. 2005-265117.

  Bolt portions 48 are joined to both sides of the plate-like portion 46. As shown in FIGS. 2 and 3A, the bolt portion 48 extends in the horizontal direction from the end of the plate-like portion 46 and penetrates the long hole 40. Then, two fixing nuts 54 are attached to the bolt portion 48 with the vertical support portion 36 interposed therebetween. By sandwiching the vertical support portion 36 with the two fixing nuts 54, the horizontal support portion 44 is supported and supported by the vertical support portion 36. Fixed. Then, as shown in FIGS. 1A and 1B, in the first to fifth supporters 16, 16... 16, the height of the lateral support portion 44 from the drainage device 24 toward the merge pipe 28 and the like. Is adjusted to be low.

  As shown in FIG. 2, the long member 18 is flexible and has a strength capable of supporting the weight of the drain pipe 20 and the weight of the drainage flowing through the drain pipe 20. For example, a wire is used. Then, as shown in FIGS. 1 (A) and 1 (B), the long member 18 is passed through the communicating holes 52 of the arranged first to fifth supporters 16, 16,... It is fixed to the communication part 50 of a certain first support 16a and the communication part 50 of the fifth support 16e. Accordingly, the long member 18 is stretched between the first support member 16a and the fifth support member 16e with a predetermined gradient, and the second and second members between the first and fifth support members 16a and 16e. 4 The support tools 16b, 16c, 16d are supported while being positioned.

  As shown in FIGS. 2 and 4, the locking tool 22 has rigidity for locking the drain pipe 20 to the long member 18 and is made of synthetic resin or metal. The locking tool 22 has a hanging portion 56 and a holding portion 58, and the hanging portion 56 and the holding portion 58 are integrally formed. The hook 56 is C-shaped, and the notch 56 a is provided below the hook 56, and the long member 18 is passed from the notch 56 a to the inside of the hook 56. The inner diameter of the hanging portion 56 is set larger than the outer diameter of the long member 18, and the upper side of the hanging portion 56 is hung on the long member 18. The holding portion 58 is C-shaped, and the notch 58 a is provided on the upper side of the holding portion 58, and the drain pipe 20 is passed from the notch 58 a to the inside of the holding portion 58. The inner diameter of the holding portion 58 is set larger than the outer diameter of the concave portion of the drain pipe 20, and the lower side of the holding portion 58 is fitted into the concave portion of the drain pipe 20.

  When forming such a drainage pipe structure 10, first, as shown in FIGS. 1 (A), 1 (B) and FIG. 2, the pipe path of the drainage pipe 20 is first formed between the through hole 26 and the junction pipe 28. Decide. At this time, the drainage pipe 20 is arranged linearly or curvedly, and when curved, the bending radius is set so that the pipe wall of the drainage pipe 20 is not bent.

  Next, in the piping path, the first support 16 a is disposed near the through hole 26, and the fifth support 16 e is disposed near the merge pipe 28. And the 2nd-4th support tools 16b, 16c, and 16d are arrange | positioned on the piping path between the 1st support tool 16a and the 5th support tool 16e at equal intervals or substantially equal intervals. When arranging each support 16, the lateral support 44 is made perpendicular to the piping path. In this case, since the vertical support portion 36 is provided in parallel to the drainage pipe 20, the drainage pipe 20 hits the end of the vertical support 16 even if the space between the vertical support portion 36 and the drainage pipe 20 is narrow. It becomes difficult.

  When the five supports 16, 16... 16 are arranged and fixed to the base 14 with screws 34, the height of the lateral support portion 44 is adjusted according to the scale 42. This height is set such that, for example, 2 when the drainage pipe 20 is attached to the drain pipe 20 and the latch 22 is locked to the long member 18, the drain pipe 20 is directed from the through hole 26 toward the junction pipe 28. It is determined to be a downward slope at / 100. For this reason, the height of each lateral support portion 44 from the first support 16a to the fifth support 16e decreases.

  Then, the long member 18 is passed through all the communication holes 52 of the five support members 16, 16... 16 so that the long member 18 does not loosen, and then the first support member 16 a and the fifth support member 16 e communicate with each other. The long member 18 is fixed by fastening the part 50. As a result, the long member 18 is positioned by the five supports 16, 16,... 16 and passes through the center of the piping path, and is supported by each support 16 to have a predetermined gradient, for example, 2/100 downward gradient. And is stretched between the first support 16a and the fifth support 16e.

  Further, the drain pipe 20 is extended from the through hole 26 to the bottom of the floor 12, the holding portion 58 is fitted into the concave portion of the drain pipe 20, and the locking tool 22 is attached to the drain pipe 20. This attachment interval is set to be narrower than the interval between the support tools 16, and a plurality of, in this embodiment, two locking tools 22 are mounted on the drain pipe 20 between the adjacent support tools 16.

  When the hooking portion 56 is hung on the long member 18 after the locking tool 22 is attached to the drainage pipe 20, the drainage pipe 20 is locked to the long member 18 by the locking tool 22, and the long member 18 Supported. Further, since the drain pipe 20 is disposed along the long member 18 with a certain distance from the long member 18, the drainage pipe 20 is supported by the first support 16a to the fifth support with a predetermined gradient, for example, 2/100 downward gradient. Piped to the tool 16e. Finally, when the end of the drain pipe 20 is connected to the junction pipe 28, the drain pipe structure 10 is completed.

  As described above, the long member 18 and the drain pipe 20 can be uniformly arranged with a predetermined downward slope only by adjusting the height of each lateral support portion 44 according to the scale 42, and the workability is excellent.

  Further, by locking the drain pipe 20 to the long member 18 with the locking tool 22, the drain pipe 20 is supported by the long member 18, and the slack and vibration of the drain pipe 20 are suppressed. Can be widened to reduce the number of supports 16. Therefore, the trouble of fixing the support 16 and the trouble of attaching the drain pipe 20 to the support 16 can be omitted, and the efficiency is increased and the operation cost can be suppressed. Moreover, the cost reduction of the support tool 16 is achieved by the number of the support tools 16 reduced.

  Furthermore, if a flexible pipe is used for the drain pipe 20, the drain pipe 20 can be rolled and carried and stored.

  Since the hook 56 is only hung on the long member 18, the locking tool 22 can move in the longitudinal direction, and the locking tool 22 can also swing in a direction perpendicular to the longitudinal direction. . Thereby, if a flexible pipe is used for the drain pipe 20, the drain pipe 20 can move flexibly against an earthquake or the like, and the drain pipe structure 10 is excellent in earthquake resistance. Moreover, even if the drain pipe 20 is thermally expanded and contracted, the thermal expansion and contraction force can be absorbed by the entire drain pipe 20, and the drain pipe 20 is prevented from being damaged.

  Even if the height of the lateral support portion 44 changes due to an earthquake or the like and the drain pipe 20 deviates from a predetermined slope, the slope of the drain pipe 20 is adjusted by adjusting the height of the lateral support portion 44 based on the scale 42. Can be easily corrected.

  In addition, the piping path of the drain pipe 20 can be easily changed simply by changing the position of the support 16, and can be applied to reforming or the like.

  In addition, although the locking tool 22 was used in the said Example, it is not limited to such a dedicated member, What can fix the drain pipe 20 to the elongate member 18 like a binding band can also be used.

  Moreover, in the said Example, although the drain pipe 20 was attached to the elongate member 18 with the latching tool 22, as shown in FIG. 5, the elongate member 18 can also be directly attached to the drain pipe 60. FIG. In this case, a bellows pipe is used for the drain pipe 60. The pipe wall of the drain pipe 60 has a smooth inner wall 60a and an uneven outer wall 60b, and a hole 62 is formed in the outer wall 60b. The hole 62 penetrates the outer wall 60b, but does not affect the inner wall 60a, and the water tightness of the drain pipe 60 is maintained by the inner wall 60a. Then, if the long member 18 is passed through the hole 62, the long member 18 is attached to the drain pipe 60.

  In the drainage pipe structure 10 which is another embodiment of the present invention shown in FIG. 6, a drainage flexible pipe 64 shown in FIG. 7 is used. Since it is the same as the drainage piping structure 10 of FIG. 1 embodiment, the same number is attached | subjected about a common part and description of the number is abbreviate | omitted.

  The outer surface of the drainage flexible tube 64 is formed in a bellows shape, and the inner surface of the drainage flexible tube 64 is formed smoothly. A plurality of hanging portions 66 are provided on the outer surface of the drainage flexible tube 64 at intervals in the axial direction, and the holding portion is integrated with the tube wall of the drainage flexible tube 64. Thereby, the locking tool is formed integrally with the drainage flexible tube 20.

  As shown in FIG. 6, when the hanging portions 66 are respectively hung on the long members 18, the drainage flexible tubes 64 are supported by the long members 18, so that the drainage flexible tubes 64 are arranged and arranged without slack. The drainage flexible pipe 64 is suppressed from vibration. For this reason, similarly to FIG. 1 embodiment, the number of the support tools 16 can be reduced, and the efficiency can be improved and the cost can be reduced.

  Further, by forming the hanging portion 66 in the drainage flexible tube 64 in advance, it is possible to save the trouble of attaching the locking tool to the drainage flexible tube 64. And since the drainage flexible tube 64 is locked to the long member 18 only by hanging this hanging part 66 on the long member 18, the drainage flexible tube 64 can be easily supported by the long member 18. .

  In all of the above embodiments, the drainage pipe 20 and the drainage flexible pipe 64 are flexible bellows pipes. However, the flexible pipes made of a soft material and the flexibility formed of a vinyl chloride resin or the like are used. It is also possible to use a straight pipe without any.

  Moreover, although the wire was used for the elongate member 18 in all the said Example, it is not limited to this, What is necessary is just the elongate thing which has flexibility and intensity | strength, for example, the elongate shown in a chain | strand or FIG. This is the member 72. The long member 72 shown in FIG. 8 is formed by connecting a non-flexible rod-like portion 68 with a C-shaped connecting portion 70, and the long member 72 has flexibility by the connecting portion 70.

  In addition, although the latching tool 22 with which the drainage pipe 20 was mounted | worn in the said all Example was latched to the elongate member 18, this latched state is only the state which fixed the latching tool 22 to the elongate member 18. In addition, it should be understood to include a state in which the locking tool 22 is simply hooked on the long member 18. When the locking tool 22 is simply hooked on the long member 18, the locking tool 22 can move in the length direction of the long member 18 and further swing in a direction perpendicular to the length direction. Can do.

  Further, the specific numerical values of the angles and dimensions given above are merely examples, and can be appropriately changed as necessary.
