When fixing a fixture F via a pair of screws B ₁ with respect to the base body V _0, 12 as (a), the bis B ₁ to one of the screw insertion holes 63 of the fixed body part 61 When the screw is inserted into the base body V ₀ , the fixed main body portion of the fixture F is fixed by the inclined pipe portions P ₃ a and P ₄ a of the pipes P ₃ and P ₄ to which the “curved ridges” are attached. One end portion of the first pipe direction Q ₁ in 61 may be lifted from the base body V ₁ in a side view. In this case, both end portions along the first piping direction Q ₁ of the bottom surface 61 a of the fixed main body portion 61 are tapered surfaces 61 b including substantially half of the lower end surface of the screw insertion hole 63. in the bis B ₁ threaded after turning, but anchoring body 61 is inclined in a side view, when threading the following bis-B _1, as shown in FIG. 12 (b), the pipe P _3, P ₄ Each of the inclined pipe portions P ₃ a and P ₄ a is forcibly bent and deformed so that the entire bottom surface 61 a of the fixed body 61 is in close contact with the second fixed surface 47 of the base body V ₀ .

Each tube P _3, the inclined pipe portion of the _{P 4 P 3 a, P 4} a is accommodated in the tube housing space K ₀ formed by the base body V ₀ and the cover body L _0.

As described above, the upper and lower end portions of the inclined pipe portions P ₃ a and P ₄ a in the pipes P ₃ and P ₄ accommodated in the inclined pipe adapter A ₀ are respectively connected via the fixture F so as not to move up and down. Since it is fixed to the base body V ₀ , the inclination of the inclined pipe portions P ₃ a and P ₄ a can be increased. In other words, even if the length (N ₀ ) along the first piping direction Q ₁ of the inclined pipe portions P ₃ a and P ₄ a is shortened, the inclined pipe portions P ₃ a and P in the pipes P ₃ and P ₄ are reduced. _{4 A} can be fixed firmly. As a result, the length of the inclined pipe adapter A ₀ along the first piping direction Q ₁ can be shortened, the area occupied by the inclined pipe adapter A _{0 on} the wall surface W is reduced, and the construction is facilitated. The appearance of the piping state is also improved.

In particular, when a “crosslinked polyethylene pipe” or “polybutene pipe” is used as the piping material, the rigidity of the pipe is high. The piping materials (pipe P ₃ , P ₄ ) piped in the upper stage are pre-attached with “bends” corresponding to the inclination angle (θ ₀ ) of the piping material in the inclined piping adapter A ₀ . "Is rarely completely coincident with the inclination angle (θ ₀ ) including the length (N ₀ ) of the inclined pipe portion. For this reason, it is necessary to further bend the highly rigid piping material previously attached with the “bend 癖” in either direction at the time of piping. In this case, the degree of bending (re-bending) is the initial “bending”. Since it is smaller than the case where “癖” is added, “re-bending” is restored to a state in which “bending 癖” is attached or a state close to this by the restoring force. However, in the present invention, the upper and lower end portions of the inclined piping portion of the piping material are respectively fixed to the first and second fixing surfaces of the base body V ₀ of the inclined piping adapter A ₀ by the fixture F and the pair of screws B _1. Since it can be securely fixed to 46 and 47 with a large force, the inclined piping portion of the piping material can be fixed to the base body V ₀ while maintaining the above-mentioned “re-bending”.

Thus, the inclined pipe portion P ₃ a of each tube _{P 3, P 4, P 4} a , even though short in length (N _0), yet the inclination angle (theta ₀₎ is large, the inclined pipe The parts P ₃ a and P ₄ a can be firmly fixed to the base body V ₀ .

Finally, the cover bodies L ₀ , L _{1 to} L ₅ are assembled to the base bodies V ₀ , V _{1 to} V _{5 of the} piping material housing members. First, as shown in FIG. 5, the cover bodies L _{1 to} L ₃ are assembled to the base bodies V _{1 to} V _{3 of the first to third} protective ducts D _{1 to} D ₃ , respectively. each assembled cover member L _0, L ₅ with respect to the base body V ₅ of the base body V ₀ and different height adapter a ₅ slope piping adapter a _0, finally, the base body V ₄ T-duct joint J ₄ Attach the cover body L ₄ to it.

In the first to third connection portions of the cover body L ₁ ~L ₃ of each protection duct D ₁ to D _3, the cover member of the T-shaped duct fittings J ₄ outside of the cover body L ₁ ~L ₃ L ₄ and the cover body L ₅ of different height adapter a ₅ is fitted by a predetermined length along the first and second respective pipes directions Q _1, Q ₂ (see FIG. 13).

An example of piping of Example 2 is shown in FIGS. The piping example of Example 2 is the same as the piping example of Example 1, except that the T-shaped duct joint J ₄ is omitted, and the holder S is used only in the upper stage of the first protective duct D _1. and the pipe P _3, P ₄ of the book is left parallelepiped, the ends of the cover body L ₁ to form a first protective one connection port C ₁₁ of the duct D _1, the cover body L ₀ of the inclined pipe adapter a ₀ Are connected to a small connecting piece 56 and have no step between the large connecting piece 55. Configuration inclined pipe adapter A ₀ of the base body V ₀ with respect to the two tubes P _3, each slope of P ₄ piping section P ₃ a, P ₄ a is fixed via the fixture F is Example 1 Is the same.

In Examples 1 and 2, the lower side of the inclined pipe adapter A ₀ (the side where the pipe height is (H ₁ )) is a straight line so that the pipes P ₃ and P ₄ can be straightly piped. Although connected to the second protective duct D ₂ , when the pipes P ₃ and P ₄ are bent at the wall surface W or penetrated through the wall surface W on the lower side of the inclined pipe adapter A ₀ , duct joint in correspondence with each of which is connected to the lower side of the inclined pipe adapter a _0.

The base body V ₀ of the inclined piping adapter A ₀ of the first embodiment includes the inclined piping surface M that is continuous along the first piping direction Q _1, and the pipes P ₃ and P ₄ on the inclined piping surface M are connected to each other. The portions necessary for the inclined piping are only the portions of the first and second fixing surfaces 46 and 47, and the inclined piping is possible even if there are no other portions.

'and the inclined pipe adapter a ₀ consisting of the cover body L ₀ Metropolitan' even, thereby enabling inclined pipe.

In the first embodiment, a total of four pipes P _{1 to} P ₄ piped in parallel at different heights are arranged in two upper and lower stages, and the center distance N ₂ between the two upper pipes P ₃ and P ₄ is provided. Since the outer diameters (nominal diameters) of the pipes P ₃ and P ₄ are smaller than the outer diameters of the other two pipes P ₁ and P ₂ , the lower two pipes P ₁ and P ₂ Since the distance is shorter than the center distance N ₁ , the clip 13 is used in the second protective duct D ₂ . However, in the case where a total of four pipes piped in parallel at different heights are piped up and down in two stages, if the outer diameters of the pipes are the same, the two pipes piped in parallel in the upper and lower stages Center-to-center distances are equal to each other, and such a two-stage pipe is also possible.

  In addition, the “two-stage piping” in the first embodiment is an example in which two pipes piped in parallel are arranged in two upper and lower stages, but two pipes arranged in a single pipe are arranged in two upper and lower stages. There may be examples, and there are various modes of “two-stage piping”.

In addition, since the length of the piping material that is “single-stage piping” from the upper stage to the lower stage of the “two-stage piping” by being bent in a side view is naturally finite, “Piping material” includes a material in which two piping materials are connected via a straight pipe joint. For example, in Example 1, when “two pipe members to be inclined piped” are connected via a straight pipe joint, the pipe joint is disposed inside the duct joint J _4. In many cases, the pipes are connected to each other.
