A pair of positioning pieces 9 provided on each base base 1 of the base V ₁ of the corner protection cover C ₁ are inserted to position the base V ₂₁ in the width direction with respect to the base V ₁ . Positioning grooves 71 are continuously formed in the longitudinal direction. The lid L ₂₁ of the straight protective cover C ₂₁ has a configuration in which a pair of side plate portions 72 are arranged facing each other with a width corresponding to the width of the base V ₂₁ and the top plate portions 73 are connected to each other. The base V ₂₁ and the lid L ₂₁ are fitted with the fitting protrusions 75 of the lid L ₂₁ into the fitting recesses 74 provided at both ends of the base V ₂₁ in the width direction. By being done, it can be assembled as one.

Next, referring to FIGS. 1 to 6, when each obstacle step portion D ₁ and D ₂ having different sizes are present at the intersection A ₀ of the wall surfaces W ₁ and W ₂ of the inside corner portion A. , And the arrangement structure of the protective cover C ₁ for the inside corner in a total of three cases when the obstacle step portion does not exist at the intersection A ₀ will be described. The obstacle step portion D ₁ is larger in size than the obstacle step portion D ₂ .

First, when a large-sized obstacle step portion D ₁ exists at the intersection A ₀ of the inside corner portion A, the base is as shown in FIGS. 1, 2 and 5-A (a). In each of the bending grooves 4a and 4c of V1, each base base portion is in a state where the small piece plate portion 3 connected to each base base portion ₁ is bent inward by an angle of 45 ° with respect to each base base base 1. When 1 is fixed to the wall surfaces W ₁ and W ₂ using screws B, each of the two small plate portions 3 connected while maintaining a flat surface has an obstacle step portion existing at the intersection A ₁ . Without interfering with D ₁ , the wall surfaces W ₁ and W ₂ are inclined at an angle of 45 ° to form an inclined base continuous portion 2a. Next, the pair of positioning pieces 9 provided on each base base 1 of the base V ₁ of the protection cover C ₁ for the inside corner is placed in each positioning groove 71 of the base V ₂₁ of the straight protection cover C ₂₁ . With the insertion and the end faces of the bases V ₁ and V ₂₁ in contact with each other, the base V ₂₁ of the straight protective cover C ₂₁ is arranged on the wall surfaces W ₁ and W ₂ . In this state, after piping the piping material P bent at the inside corner A on each base V ₂₁ of the straight protective cover C ₂₁ fixedly arranged on each wall surface W ₁ and W ₂ , each wall surface W Assemble the lid L ₂₁ integrally to each of the bases V ₂₁ of ₁ and W ₂ .

Finally, as shown in FIG. 2, each side plate is formed by folding each side plate 11 of the lid L ₁ of the inner corner protective cover C ₁ into an isosceles right triangle shape at the break groove 15. A missing corner portion 19 is formed in a portion of the portion 11 that faces the portion provided with the top plate portion 12 in the diagonal direction, and is fixed to the inside corner portion A where the wall surfaces W ₁ and W ₂ intersect. The lid L ₁ is integrally assembled with the base V ₁ of the arranged corner protection cover C ₁ . As a result, as shown in FIG. 5-A (a), each side plate portion 11 of the lid L ₁ has an obstacle step portion existing at the intersection A ₀ of the inside corner portion A due to the missing corner portion 19. The lid L ₁ is assembled to the base V ₁ while the interference with D ₁ is avoided. In FIG. 2, 21 indicates a broken piece.

Here, if a large obstacle step portion D ₁ exists at the intersection A ₀ of the inside corner portion A, both ends of the base V ₁ in the longitudinal direction are formed on the wall surfaces W ₁ and W ₂ , respectively. Only the base 1 of each base is fixedly arranged, and the base V ₁ passes through the intersection A ₀ of each wall surface W ₁ and W ₂ , and at 45 ° to each wall surface W ₁ and W ₂ . It is arranged symmetrically with respect to the intersecting planes of symmetry K [see FIG. 5-A (a)]. As a result, each fitting protrusion 14 of the lid L ₁ is located at a position slightly displaced toward the small plate portion 3 with respect to the center in the longitudinal direction of each of the linear fitting portions 6 of the base V ₁ . Arranged, as shown in FIG. 6, the fitted portion 6 of the base V ₁ and the fitting projection 14 of the lid L ₁ are fitted to each other at the above positions.

Further, when a small obstacle step portion D ₂ is present at the intersection A ₀ of the inside corner portion A, as shown in FIGS. 3 and 5A (b), each bending groove 4a is formed. , 4b (or 4b, 4c), bend the base V ₁ inward by an angle of 45 °, fix only one base base 1 on one wall surface W ₁ , and fix it on the other wall surface W ₂ . When the other base base 1 and one small plate 3 connected to the base base 1 are fixedly arranged, the other small plate 3 is inclined at an angle of 45 ° with respect to the wall surfaces W ₁ and W ₂ , respectively. By being arranged to form the inclined base continuous portion 2a, interference with the obstacle stepped portion D ₂ existing at the intersection A ₀ of the inside corner portion A is avoided, and the base V is provided at the inside corner portion A. ₁ is fixedly placed.

Then, the corner portion of each side plate portion 11 of the lid L ₁ facing the top plate portion 12 in the diagonal direction is cut off at the portion of the folding groove 16 in an isosceles right triangle shape to form the missing corner portion 22. The lid L ₁ is integrated with the base V ₁ fixedly arranged on the wall surfaces W ₁ and W ₂ by the fitting structure of the fitted portion 6 and the fitting protrusion 14. Assemble. Here, since the base V ₁ fixedly arranged on the wall surfaces W ₁ and W ₂ is arranged asymmetrically with respect to the plane of symmetry K, the base V ₁ has a lid on the linear fitted portion 6. The fitting position of the fitting protrusion 14 of the body L ₁ along the arrangement direction Q of the piping material P was fixed to the wall surface W ₁ with respect to the fitting position of the above-mentioned large obstacle step portion D ₁ . Displaced toward the base portion 1, each fitting projection 14 of the lid L ₁ is fitted at an end portion in the longitudinal direction with respect to each fitted portion 6 of the base V ₁ . In FIG. 3, 23 shows a broken piece of the side plate portion ₁₁ of the lid L1.

Further, when there is no obstacle step portion at the intersection A ₀ of the inside corner A, the base V ₁ is formed at the bent groove 4 b as shown in FIGS. 4 and 5-B (c). By bending at a right angle, each portion to which the base base portion 1 and one small plate portion 3 are connected is fixedly arranged on the wall surfaces W ₁ and W ₂ , and the folding grooves 15 and 16 of the side plate portions 11 are formed. The lid L ₁ is integrally assembled to the base V ₁ fixedly arranged on the wall surfaces W ₁ and W ₂ by the above fitting structure, while leaving the corners.

When there is no obstacle step portion at the intersection A ₀ of the inside corner A, the base V ₁ fixedly arranged on the wall surfaces W ₁ and W ₂ is arranged symmetrically with respect to the symmetry plane K. In the case where the obstacle step portion D ₁ having a large size is present, the fitting projections 14 of the lid L ₁ with respect to the linear fitting portions 6 of the base V ₁ are arranged in the arrangement direction Q. Each is fitted at a position displaced outward along the line.

In this way, the shape of the fixed arrangement of the base V ₁ with respect to each wall surface W ₁ and W ₂ is different, so that the arrangement position of each fitted portion 6 of the base V ₁ with respect to each wall surface W ₁ and W ₂ is a pipe. Even if the material P is displaced along the arrangement direction Q, each fitted portion 6 formed on the base V ₁ is formed in a linear shape along the arrangement direction Q of the piping material P. The fitting position of each fitting protrusion 14 of the lid L ₁ is displaced with respect to each fitting portion 6 of the base V ₁ fixedly arranged on the wall surfaces W ₁ and W ₂ .

Next, the protective cover C2 for the inside corner of the _second embodiment of the invention of claims 1 to 5 and 9 will be described with reference to FIGS. 10 to 14. The protective cover C ₂ for the inside corner has a rectangular base V ₂ whose overall shape has a long side along the arrangement direction Q of the piping material P, and a lid L which is integrally attached to the base V ₂ . Consists of ₂ . The base V ₂ has a configuration in which a pair of rectangular plate-shaped base bases 31 fixedly arranged on the wall surfaces W ₁ and W ₂ are connected by a base continuous portion 32. In the base continuous portion 32, a plurality of rectangular small plate portions 33 (three in the embodiment) are connected so as to be bendable at the bent grooves 34b and 34c, and each base base 31 and the corresponding base portion 31 are connected to each other. The small plate portion 33 connected to each base base portion 31 is foldably connected to each other via the bending grooves 34a and 34d, respectively. The base V ₂ is provided with a screw insertion hole 7, a screw pilot hole 8, and a positioning piece 9 in the same manner as the base V ₁ .

Since the lid L ₂ has the same configuration as the lid L ₁ , the same parts are designated by the same reference numerals, and only different parts will be described. That is, as shown in FIG. 12, the lid L ₂ is provided with respect to the top plate portion 12 on the inner side surface of the pair of side plate portions 11 arranged to face each other at intervals corresponding to the width of the base V ₂ . At the corners facing each other along the diagonal direction, a pair of first locking projections 36 and one second locking projection 37 have an angle of 45 ° with respect to both the contact end faces 17 and 18 orthogonal to each other. It is formed along the direction of inclination with. The pair of first locking projections 36 are formed inside the corners 38 of the contact end faces 17 and 18 with respect to one second locking projection 37. As shown in FIGS. 13 and 14, the one-to-one set of the first locking projection 36 and the one second locking projection 37 is an inclined base continuous portion composed of a total of three small plate portions 33. It is locked to each back surface of the inclined base continuous portion 32a composed of the 32a and the central small piece plate portion 33. The locking surface formed at the portion of the first and second locking projections 36 and 37 most distant from the corner portion 38 is formed perpendicular to the inner surface of each side plate portion 11.

Therefore, as shown in FIG. 10A, all the small plate portions 33 constituting the base continuous portion 32 are in an inclined arrangement with respect to the wall surfaces W ₁ and W ₂ of the inside corner portion A. When the base V ₂ is fixedly arranged on the wall surfaces W ₁ and W ₂ , all the small plate portions 33 function as the inclined base continuous portion 32 a and are fixed to the wall surfaces W ₁ and W ₂ . When the lid L ₂ is pressed against the arranged base V ₂ from the direction perpendicular to the inclined base continuous portion 32a and the second locking projection 37 reaches the portion of the inclined base continuous portion 32a, Each of the facing side plate portions 11 is expanded and deformed outward, and the second locking projection 37 gets over the inclined base continuous portion 32a. Further, when the pair of first locking projections 36 are pressed against the lid L ₂ and reach the portion of the inclined base continuous portion 32a, the opposing side plate portions 11 are again expanded and deformed outward. When the pair of first locking projections 36 of the lid L ₂ are arranged on the back surface of the inclined base continuous portion 32a of the base V ₂ , each side plate portion 11 has the original shape as shown in FIG. The pair of first locking projections 36 of the lid L ₂ are locked to the inclined base continuous portion 32a of the base V ₂ .

In the locked state described above, the contact end faces 17 and 18 of the lid L ₂ are in contact with the wall surfaces W ₁ and W ₂ , and the inclined base continuous portion 32a of the base V ₂ and the lid L ₂ are in contact with each other. Since the pair of first locking projections 36 are all inclined at an angle of 45 ° with respect to the wall surfaces W ₁ and W ₂ , the lid L with respect to the base V ₂ is provided only by the locking structure. No. ₂ becomes immovable in all directions, and the lid L ₂ is integrally assembled with the base V ₂ .

Further, as shown in FIG. 10B, only the central small plate portion 33 constituting the base continuous portion 32 is inclinedly arranged on the wall surfaces W ₁ and W ₂ , and the base V ₂ When is fixedly arranged on each wall surface W ₁ and W ₂ , as shown in FIG. 14, one second locking projection 37 near the corner 38 in the lid L ₂ is on the base V ₂ . The lid L ₂ is integrally assembled to the base V ₂ by being locked to the back surface of the central small plate portion 33 constituting the base continuous portion 32.

Regarding the assembly of the base and the lid that constitute the protective cover for the inside corner, the contact end faces 17 and 18 of the lid L ₂ are in contact with or close to the wall surfaces W ₁ and W ₂ , respectively. Therefore, even with the above-mentioned locking structure alone, the lid can be immovably assembled to the base fixedly arranged on each wall surface in all directions. However, the locking structure and the base can be assembled. It is more reliable when the fitting structure of the first embodiment of the configuration in which the fitting position between the linear fitted portion and the fitting portion of the lid is displaced along the arrangement direction of the piping material is used in combination. In addition, the base and the lid can be assembled integrally. Regarding the assembly of the base and the lid that constitute the protective cover for the inside corner, it may be used properly depending on the presence or absence of the obstacle step portion when only the fitting structure or only the locking structure is used.

Further, in the second embodiment, the first and second locking projections 36, 37 provided on the lid L ₂ are locked on the back surface side of the inclined base continuous portion 32a of the base V ₂ . However, it is also possible to lock it on the surface side.

Next, with reference to FIG. 15, the base V ₃ constituting the inner corner protective cover C ₃ according to the third embodiment of the invention of claim 6 will be described. The base V ₃ connects the base connecting portion 2 connecting the pair of base bases 1 of the base V ₁ of the first embodiment to the base connecting portion 2 ′ in the form of a thin sheet having flexibility. Since the remaining configuration is the same as that of the base V ₁ , the same reference numerals are given to explain only the flexible base continuous portion 2'which is a characteristic part. do. Since the base continuous portion 2'is formed in a sheet shape thinner than the base base 1 and has flexibility, an obstacle step portion D ₁ exists at the intersection A ₀ of the inside corner portion A. However, by arranging each base base 1 fixedly on each wall surface W ₁ and W ₂ , the base continuous portion 2'is freely bent and deformed according to the size of the obstacle step portion D ₁ . , The base V ₃ can be fixedly arranged at the inside corner A while avoiding the obstacle step portion D ₁ .

Next, the base V ₄ of the fourth embodiment will be described with reference to FIG. The fitted portion 6 of the base V1 of the _first embodiment is formed linearly by a predetermined length along the arrangement direction Q of the piping material P, and the horizontal step surface shape is a claw shape. The fitted portion 6'of the base V ₄ of 4 has a wide gate shape in a side view, and both ends in the longitudinal direction of the fitted plate portion 6'a arranged in the arrangement direction Q are the bases. Only the configuration in which the fitted space portion 6'c is formed between the fitted plate portion 6'a and the base base portion 1 by being fixed to the base portion 1 via the leg portion 6'b is available. , Different from the base _V1 . The base V ₄ is assembled with the lid L ₁ of the first embodiment.

Therefore, when a large obstacle step portion D ₁ exists at the intersection A ₀ of each wall surface W ₁ and W ₂ , as shown in FIG. 16 (a), two small pieces of the base V ₄ are provided. The portion 3 is bent to function as the inclined base continuous portion 2a, and the base V ₄ is fixedly arranged on the wall surfaces W ₁ and W ₂ , and in this state, the lid is attached to the base V ₄ . When L ₁ is pressed and assembled integrally, each fitting protrusion 14 of the lid L ₁ is inserted into the fitted space portion 6'c, and is in a state of being close to the inner leg portion 6'b. It is fitted to each fitted plate portion 6'a. On the other hand, when there is no obstacle step portion at the intersection A ₀ , as shown in FIG. 16 (b), each fitting projection 14 of the lid L ₁ is close to the outer leg portion 6'b. In this state, it is fitted to each fitted plate portion 6'a. Further, although not shown, when a small obstacle step portion D ₂ is present at the intersection A ₀ , each fitting projection 14 of the lid L ₁ is a fitted plate portion 6'of the base V ₄ . Fitted at the middle of each leg 6'b in a. The base V ₄ of the fourth embodiment has a lid L ₁ in the case where a large obstacle step portion D ₁ exists at the intersection A ₀ of the wall surfaces W ₁ and W ₂ , and when the obstacle step portion D 1 does not exist. Because the placement position with respect to the base 1 and its length are determined so that the fitting protrusion 14 is close to the legs 6'b at both ends along the placement direction of the fitted portion 6'. There is an advantage that the mating state between the base V ₄ and the lid L ₁ is stabilized.

Next, the base V ₅ of the fifth embodiment of the invention of claim 7 shown in FIG. 17 will be described. The base V ₅ of the fifth embodiment is also assembled to the lid L ₁ of the first embodiment. The base V ₅ differs from the base V ₁ of the first embodiment only in the configuration of the fitted portion 6, and the fitting projection 14 of the lid L ₁ is slightly along the arrangement direction Q. The only difference is the configuration in which the gate-shaped fitted portion 6 ”is provided in the side view to be fitted with a gap of the above. As shown in FIG. 17 (b), each wall surface W ₁ , When a large obstacle step portion D ₁ exists at the intersection A ₀ of W ₂ , the two small plate portions 3 are bent inward at a right angle to form a step avoidance portion 20 and become an interference avoidance space portion. When 10 is formed and there is no obstacle step portion, as shown by a two-dot chain line in the figure, each small plate portion is a portion of a bending groove 4b connecting each small plate portion 3. 3 is bent at a right angle and fixedly arranged in the inside corner portion A. As a result, in the above two arrangement modes, the arrangement position along the arrangement direction Q of each fitted portion ₆ of the base V5. Is the same, so that the fitted space 6 "c of the fitted portion 6" has a slight gap along the arrangement direction Q in the inserted fitting state of the fitting projection ₁₄ of the lid L1. It is only necessary to form.

It relates to the protective cover connectors E ₁ and E ₂ .

The protective cover connection body E ₁ is shown in FIGS. 18 to 23, and is attached to the base V ₁₁ fixed to the building wall W ₁₁ while avoiding the obstacle step portion D ₁₁ and the base V ₁₁ . It consists of a lid L ₁₁ . As shown in FIGS. 20 to 23, the base V ₁₁ has a rectangular overall shape having long sides along the arrangement direction Q of the piping material P, similarly to the base V ₁ . The pair of base bases 41 are connected by a base continuous portion 42. The base continuous portion 42 has a configuration in which a plurality of (five pieces in the embodiment) rectangular small plate portions 43 are foldably connected at the portion of the bending groove 44, and is connected to each base base 41. , Each small plate portion 43 connected to each base base portion 41 is foldably connected to each other by a bending groove 44. Partial standing walls 45 are formed at both ends of each base base 41 in the width direction R along the arrangement direction Q, and fitted protrusions 46 are arranged at the outer upper ends of each partial standing wall 45 in the arrangement direction. It is formed along Q. A positioning side 47 is formed on the outside of each base portion 41 in the central portion in the width direction R, and a screw insertion hole 48 is formed in the central portion in the width direction of each base base 41.

As shown in FIGS. 21 and 22, the lid L ₁₁ has a pair of side plate portions 51 which are opposed to each other at intervals corresponding to the width of the base V ₁₁ and are connected by the top plate portion 52. The cross section has an inverted U shape, and each opening at both ends of the piping material P along the arrangement direction Q serves as a connection port 53 connected to the end of the straight protective cover C ₂₁ . At the same time, the opening formed between the lower ends of each side plate portion 51 is an assembly opening 54 for assembling with the base V ₁₁ . The inner side surface of each side plate portion 51 arranged to face each other, and the central portion of the lower end portion thereof is to be folded off in order to avoid interference with the obstacle step portions D ₁₁ and D ₁₂ existing on the building wall W ₁₁ . Each of the square-shaped thin-walled thin-walled parts to be removed 55 is formed, and on both sides of the part to be removed 55, each of the linear shapes to be fitted with each of the fitted projections 46 of the base V ₁₁ is formed. The fitting portion 56 is formed up to the inner portion of the connection port 53. Each fitting portion 56 has an equal length and is arranged symmetrically with respect to the planned removal portion 55. By breaking off the planned removal portion 55 of each side plate portion 51, an interference avoidance opening 57 (see FIGS. 18 and 19) that can avoid the obstacle step portions D ₁₁ and D ₁₂ is formed. It should be noted that the base V ₁₁ and the lid L ₁₁ are assembled to the end of each of the linear fitting portions 56 on the side of the connection port 53 by fitting, and the base V 11 is attached to the base V ₁₁ . A stopper portion 58 is formed to prevent the lid L ₁₁ from sliding in the arrangement direction and coming off.

Then, when the obstacle step portion D ₁₁ exists on the building wall W ₁₁ , as shown in FIGS. 18, 19 and 23 (a), the base continuous portion 42 of the base V ₁₁ Of the plurality of bent grooves 44 formed in the connecting portion of each small plate portion 43, in all the remaining bent grooves 44 except for the two bent grooves 44 connected to each base base 41. By bending each small plate portion 43 into an isosceles trapezoidal shape to form an interference avoidance space portion 59, the base V ₁₁ is fixedly arranged on the building wall W ₁₁ while avoiding the obstacle step portion D ₁₁ . In this state, the positioning piece 47 of the base V ₁₁ is inserted into the positioning groove 76 at the longitudinal end of the base V ₂₁ of the straight protective cover C ₂₁ , and the base V of the protective cover connector E ₁ is inserted. Position the base V ₂₁ of the direct protection cover C ₂₁ with respect to ₁₁ in the width direction, and connect the base V ₂₁ to both ends of the base V ₁₁ in the arrangement direction Q. In this state, after piping the piping material P on the bases V ₁₁ and V ₂₁ , the lid L ₂₁ is attached to each base V ₂₁ of the direct protection cover C ₂₁ .

Finally, when the lid L ₁₁ is pressed against the base V ₁₁ fixedly arranged on the building wall W ₁₁ to avoid interference with the obstacle step portion D ₁₁ , the base is as shown in FIG. Each of the fitted protrusions 46 of V ₁₁ and the fitting portion 56 of the lid L ₁₁ are fitted to each other, and the base V ₁₁ and the lid L ₁₁ are integrally assembled.

Further, when the obstacle step portion D ₁₂ existing on the building wall W ₁₁ is large, as shown in FIG. 23 (b), the outermost two bending grooves 44 among the plurality of bending grooves 44 are formed. Using a total of four bending grooves 44 including, each small piece plate portion 43 of the base V ₁₁ is used to form an isosceles trapezoidal interference avoidance space portion 59'which is larger than the interference avoidance space portion 59. By forming it, interference with the obstacle step portion D ₁₂ is avoided.

Further, when there is no obstacle step portion on the building wall W ₁₁ , as shown in FIG. 23 (c), the base continuous portion 42 of the base V ₁₁ is left in a flat plate shape and has a lid. The parts to be removed 55 of each side plate portion 51 of the body L ₁₁ are left to be used as a normal base V ₁₁ and a lid L ₁₁ .

As shown in FIG. 23, since there is no obstacle step portion on the building wall W ₁₁ , when the base continuous portion 42 of the base V ₁₁ is used as a flat plate, the base V ₁₁ The fitting position between the fitted protrusion 46 and the fitting portion 56 of the lid L ₁₁ is a position close to the inside of the stopper portion formed inside the connection port 53 of each side plate portion 51 of the lid L ₁₁ . When the obstacle step portions D ₁₁ and D ₁₂ are present, the fitting position is a position having a slight gap inside the stopper portion. Therefore, in the fitted state between the base V ₁₁ and the lid L ₁₁ , the lid L ₁₁ does not slide significantly with respect to the base V ₁₁ .

Next, with reference to FIGS. 24 and 25, another protective cover connecting body E ₂ in which only a portion of the fitting structure of the protective cover connecting body E ₁ described above is modified will be described.

The protective cover connecting body E ₂ is composed of a base V ₁₂ and a lid L ₁₂ assembled to the base V ₁₂ . In the protective cover connecting body E ₁ , each fitting portion 56 formed at the lower end portion of the inner side surface of each side plate portion 51 of the lid body L ₁₁ has the same length and is symmetrical with respect to the planned removal portion 55. Although it is arranged, in the protective cover connecting body E ₂ , the removal scheduled portion 55'is formed long along the arrangement direction Q by entering the side of one fitting portion 56, and is scheduled to be removed. Fitting portions 56 and 56'of different lengths are formed on both sides of the portion 55', respectively. The short fitting portion 56'is fitted in a state where the fitting projection 46 of the base V ₁₂ is arranged with a slight gap between the stopper portions 58 on both sides. The arrangement position of the lid L ₁₂ along the arrangement direction Q with respect to one base base 41 of the base V ₁₂ is different from that of the protective cover connection body E ₁ in a constant configuration. By bending each small plate portion 43 of the base _V12 to form an interference avoidance space portion 59 that avoids interference with the obstacle step portion, the fitting portion 56 on the long side is formed. In the positioning piece 47', the entire decrease in the length of the base V ₁₂ shortened along the arrangement direction Q due to the bending of each small plate portion 43 enters the inside of the lid L ₁₂ . The positioning piece 47'of the base V ₁₂ on the side of the fitting portion 56 is longer than the other positioning pieces 47.

Therefore, as shown in FIG. 25 (a), in order to avoid the obstacle step portion D ₁₁ existing on the building wall W ₁₁ , each small plate portion 43 is bent to form the interference avoidance space portion 59. In both cases and as shown in FIG. 25 (b), since there is no obstacle step portion on the building wall W ₁₁ , the entire small plate portion 43 is used in a flat plate shape without bending. The arrangement position (assembly position) of the lid L ₁₂ with respect to one base base 41 of the base V ₁₂ along the arrangement direction Q is unchanged, and in the assembled state, with respect to the base V ₁₂ . The lid L ₁₂ cannot slide.

In addition, when removing the planned removal portions 55 and 55'formed on the lids L ₁₁ and L ₁₂ by avoiding the interference with the obstacle step portion, if the removal is performed according to the outer shape of the obstacle step portion, the removal is performed. There is no gap between the obstacle and the stepped portion, and the appearance is improved.
