Each of the ₀ side plate portions 51 is restored to the original shape and is covered with the base V ₀ without removing the lid L ₀ (see FIG. 1).

And in order to fix the protective cover K ₀ in a state where it is raised by the height (H ₁ + H ₂ ) with respect to the wall surface W by using the heat insulating material placement tool A ₁ and the spacer S, it is performed as follows. . FIG. 5 is a cross-sectional view of a state in which the heat insulator placement tool A ₁ and the spacer S are assembled and fixed to the wall surface W. First, as shown in FIG. 5, when the heat insulating material placement tool A ₁ is strongly pressed against the spacer S, the contact leg portion 14 c of the heat insulating material placement device A ₁ is slightly bent inward, and the heat insulating material placement material A ₁ is bent. The locked protrusion 21 of the tool A ₁ and the locking protrusion 33 of the spacer S are locked and connected to each other. In the state where the heat insulating material arranging tool A ₁ and the spacer S are connected as described above, there is a slight gap with respect to the separation direction. Further, as shown in FIG. 5, of the four pairs of contact leg portions 14 a to 14 d that form a one-to-one pair that constitutes the heat insulating material placement tool A ₁ , the contact formed with the locked protrusion 21. Only the leg portion 14c does not contact the main body plate portion 31 of the spacer S, and all the remaining contact leg portions 14a, 14b, 14d are in contact with the main body plate portion 31 of the spacer S. In addition, with respect to the spacer S, only the contact legs 34a and 34d at the center and both end portions are in contact with the wall surface W, and the remaining contact legs 34b and 34c are not in contact with the wall surface W. There is a slight gap between the wall surface W and the wall surface W.

Then, as shown in FIG. 5, a plurality at predetermined intervals in the longitudinal direction in the portion of the first positioning recessed streak 22a formed in the central portion in the width direction of the main plate portion 11 of heat insulating material disposed tool A ₁ By screwing in the screw B ₁ , the heat insulating material arranging tool A ₁ and the spacer S are integrated, and the integrated heat insulating material arranging tool A ₁ and the spacer S are fixed to the wall surface W. Next, when the heat insulating material D ₁ is bent in the width direction and both end portions thereof are inserted and accommodated in the heat insulating material accommodating portions 15 of the heat insulating material arranging tool A ₁ , the heat insulating material D ₁ is easily obtained. with no exit, and it is flat on the upper surface of the main plate portion 11 of heat insulating material disposed device a _1. As shown in FIG. 1, the heat insulating material D ₁ arranged in a plane inside the heat insulating material disposing tool A ₁ accommodates the piping material in the protective cover K _{0 that} covers the base V ₀ with the lid body L _0. The space 50 corresponds to almost all parts in a plan view (the heat insulating material D ₁ exists in all parts of the piping material accommodation space 50 in the width direction). Both the heat insulating material D ₁ and the heat insulating material D ₀ are formed of a lightweight resin foam and are slightly compressed and deformed.

Then, by pressing the base V ₀ which protective cover K ₀ with respect to the heat insulating material disposed tool A ₁ which is fixed to the wall W via the screw B ₁ a plurality of locking projections insulation arrangement device A ₁ When the locked protrusion 43 of the base V ₀ is locked to the base 18, the base V ₀ is connected to the heat insulating material arranging tool A ₁ fixed to the wall surface W. In this state, when screwing the screws B ₂ in the portion immediately below each holding space 46 in the fixed portion 41 of the base V ₀ to the portion of the wall surface W, the bis B ₂ is heat-insulating material disposed device A ₁ and the spacer S In the state where the main body plate portions 11 and 31 are passed through and the heat insulating material placement tool A ₁ and the spacer S are interposed between the main body plate portions 11 and 31 and the wall surface W, the screw B ₂ is raised by a height (H ₁ + H ₂ ). The base V ₀ is fixed to the wall surface W via In this state, it is received and held respectively the water supply pipe P ₁ and hot water supply pipe P ₂ each holding space 46 of the base V _0, and then to cause the covering the lid L ₀ relative to the base V _0.

Since each width (F) of the protective cover K ₀ , the heat insulating material arranging tool A ₁ and the spacer S is the same, the protective cover K ₀ is raised and fixed to the wall surface W by a height (H ₁ + H ₂ ). Does not recognize the heat insulating material placement tool A ₁ and the spacer S, and the whole is recognized as one protective cover K ₀ , so that the appearance of the protective cover K _{0 in} a fixed state is improved (the aesthetic appearance is maintained). ) Further, as shown in FIG. 1, the piping material accommodation space 50 formed inside by covering the lid body L ₀ on the base V ₀ has a heat insulation whose entire circumference is accommodated in the heat insulation material arrangement tool A _1. Since it is covered with the heat insulating material D ₀ disposed on the inner peripheral surface of the lid L ₀ of the material D ₁ and the protective cover K ₀ , the pipe material accommodation space 50 is not narrowed at all without narrowing the piping material accommodation space 50. The heat insulation of the water supply pipe P ₁ and the hot water supply pipe P ₂ held in each holding space 46 is enhanced.

The use of heat insulating material disposed device A ₁ and the spacer S, the protective cover K ₀ is established because it is raised by a height relative to the wall surface _{W (H 1 + H 2)} , a protective cover K ₀ directly to the wall W ( In the case of fixing), the interference can be avoided when it interferes with an interference existing on the wall surface W. In order to avoid interference with an interference object existing on the wall surface W, a “lifting height” corresponding to the height of the interference object is required. Therefore, the number of the heat insulator placement tool A ₁ and the spacer S is appropriately selected. Then, as described above, they are overlapped and connected for use.

Further, in the heat insulating material arranging tool A ₂ shown in FIG. 4 (b), the connecting plate portion 19 is omitted from the heat insulating material arranging tool A _{1 and} the width of the heat insulating material accommodating portion 15 ′ is increased (heat insulating material). The insertable dimension at the end of the width direction of D ₁ ′ is increased), and the width of the heat insulating material D ₁ ′ that can be installed is increased. Thereby, the heat insulation of the fixing cover 41 side of the protective cover K ₀ is further enhanced.

In addition, each of the above-described heat insulating material placement tools A ₁ and A ₂ is configured such that the entire heat insulating material D ₁ is within the thickness along the thickness direction of the heat insulation material placement tools A ₁ and A _2. However, in the range where the original heat insulating function is not hindered even if the heat insulating material is compressed and deformed, a part along the thickness direction of the heat insulating material protrudes to one side of the thickness direction of the heat insulating material arranging tool (extruded) ) Configuration. When the heat insulating material protrudes toward the wall surface with respect to the heat insulating material arranging tool, in use, the protruding portion of the heat insulating material is compressed in close contact with the wall surface or another spacer overlapped with each other. When the heat insulating material protrudes toward the protective cover with respect to the arrangement tool, the protruding portion of the heat insulating material is compressed in close contact with the protective cover.

Next, the piping material protection covers K _{1 to} K _{3 according} to the present invention will be described with reference to FIGS. FIGS. 6A and 6B are cross-sectional views of the base V ₁ and the protective cover K _{1 in} use. Protective cover K ₁ consists lid L ₁ Tokyo that is covering the base V ₁ and the base V _1. The base V ₁ is a fitting portion 63 in which a pair of holding pieces 61 arranged opposite to each other are integrally formed with the fixing portion 62 in a standing state, and the base end portions of the pair of holding pieces 61 are formed in a concave shape. It is a configuration. The fixing portion 62 includes a contact portion 62a at both end portions in the width direction and a non-contact portion 62b at the center portion in the width direction formed by raising the contact portion 62a. A pair of left and right abutment legs 68 that abut against the wall surface W are erected on both sides of the abutment part 62 b, a lower surface 62 b ₁ of the non-abutment part 62 b, The groove-shaped part opened in the lower surface formed by is a heat insulating material accommodation groove 64 capable of accommodating the heat insulating material D ₁₁ . Each of the pair of left and right holding pieces 61 is formed continuously at the tip of the pair of contact leg portions 68. The heat insulating material accommodating groove 64, without thickness sheet insulation material D ₁₁ is compressed in the thickness direction, moreover disposed in the same plane as the abutment surface of the lower surface of the contact portion 62a of the fixed portion 62 is accommodated in a state of being, it is adhered to the lower surface 62b ₁ and the inner surface 62a _1.

On the other hand, the lid body L ₁ is connected by a top plate portion 66 formed by bending a pair of side plate portions 65 arranged to face each other, and the fitted portion 67 is opposed to the inner side of the lower end portion of each side plate portion 65. is formed, the inner surfaces of the pair of side plate portions 65 and the top plate 66 is stuck heat insulating material D _12, both end portions in the width direction, the formed by the fitted portion 67 and the side plate portion 65 It is inserted into the groove-like portion 69.

Then, after being held in place in the holding space 60 between the pair of holding pieces 61 of the base V ₁ of hot water supply pipe P _2, when pushed the lid L ₁ with respect to the base V _1, base V _The fitted portion 67 of the lid L ₁ is fitted to each of the fitting portions 63, and the lid L ₁ is covered with respect to the base V ₁ . In this state, all parts except for the wall surface W side in the hot water supply pipe P ₂ accommodated in the protective cover K ₁ are covered with the heat insulating material D ₁₂ attached to the inner side surface of the lid L ₁ . The wall surface W side of the hot water supply pipe P ₂ is covered with a heat insulating material D ₁₁ accommodated in the accommodation groove 64 of the fixing portion 62 of the base V ₁ . Therefore, hot water supply pipe P ₂ has its entire periphery covered with a heat insulating material D ₁₁ and the D _12, heat insulation is enhanced. In particular, the heat insulating material D ₁₁ accommodated in the accommodating groove 64 formed in the base V ₁ is arranged between the wall surface W having a large heat transfer without narrowing the heat insulating material accommodating space of the protective cover K ₁ at all. Therefore, the heat insulation is greatly improved.

Next, with reference to FIGS. 7 and 8, only different portions of the protective cover K ₁ will be described for the other protective covers K ₂ and K ₃ . Each protective cover K _2, K _3, since containment configuration of the heat insulating material D _21, D ₃₁ with respect to the fixed portion 71,82 of the base V _2, V ₃ are different only in the protective cover K ₁ and identical parts Only the different parts will be described with the same reference numerals. Figure 7 (b), the protective cover K ₂ shown in (b), with undercut grooves 74a at both ends in the width direction of the heat insulating member receiving groove 74 formed on the base V ₂ is formed, a heat insulating material D both end portions of the ₂₁ width direction is to be inserted to the each undercut groove 74a, it is possible to accommodate without exiting insulation D ₂₁ in the heat insulating material housing groove 74 without using an adhesive or the like, the fixing portion An inclined surface portion 62c is formed on the upper surface of 62, and each of the undercut groove portions 74a is formed in a portion of the contact leg portion 68. width is wider for accommodating groove 74, the width of the heat insulating material D ₂₁ becomes wider, there is an advantage that heat insulation is enhanced. Note that the heat insulating material D ₂₁ slightly enters the accommodation groove 74 rather than the contact surface on the lower surface of the contact portion 62a of the fixed portion 62, and is not compressed at all.

The protective cover K ₃ shown in FIG. 8 has a heat insulating property enhanced by increasing the width of the heat insulating material D ₃₁ accommodated in the fixing portion 82 of the base V ₃ . That is, the plate thickness of the fixing portion 82 of the base V ₃ is formed to be thicker than the plate thickness of the fixing portion 62 of the base V ₁ , and the heat insulating material is formed on the contact surface side of the fixing portion 82. The width of the groove 84 is increased. Therefore, the heat insulating material D ₁₁ wide heat insulating material accommodating a D ₃₁ than is enabled, an amount corresponding thermal insulation width of the heat insulating material D ₃₁ becomes wider enhanced. In FIG. 8, reference numeral 82a denotes contact leg portions formed at both ends of the fixing portion 82 in the width direction. 6 (a), FIG. 7 (a) and FIG. 8 (a) are two-dot chain circles, which are the outer shapes of the hot water supply pipes P ₂ held by the pair of holding pieces 61, and the hot water supply pipes P _2.

Since the heat insulating material D ₄₁ having a large thickness (T) is accommodated, a part of the heat insulating material D _{41 in} the thickness direction slightly protrudes from the contact surface 82 b on the lower surface of the fixed portion 82. Therefore, when fixing the fixing portion 82 of the base V ₃ using screws B ₃ to the wall surface W, the thermal insulator D ₄₁ is compressed by the projecting amount (crushed monkey). The amount of compression of the insulation material D ₄₁ [T-J], it is necessary to extent the function is not compromised as a heat insulator, when the excessively compressed insulation is impaired.

Each of the protective covers K _{1 to} K ₃ described above is provided with the heat insulating material D in the heat insulating material receiving grooves 64, 74, and 84 formed on the side where the fixing portions 62 and 82 of the bases V _{1 to} V ₃ are installed on the wall surface W. ₁₁ , D ₂₁ , D ₃₁ , D ₄₁ are accommodated, and hot water is supplied by the heat insulating materials D ₁₁ , D ₂₁ , D ₃₁ , D ₄₁ and the heat insulating material D ₁₂ affixed to the inner surface of the lid L _1. Since the entire circumference of the pipe P ₂ is covered, the heat insulation of the hot water supply pipe P ₂ , in particular, the heat insulation between the wall W having a large heat transfer, without narrowing the heat insulating material accommodation space of each of the protective covers K _{1 to} K _3.
