Description

[Technical Field]

[0001] The present invention relates to an accessory protective cover for wiring and piping materials that can be placed while avoiding interference with trim materials placed in the inside corners of building walls, and a method for placing an accessory protective cover in the inside corners. [Background technology]

[0002] Patent Document 1 discloses an accessory protective cover for wiring and piping material, in which an inside corner of a building is formed by first and second wall surfaces that are orthogonal to each other, and which is provided with a peripheral wall portion having first and second end faces that abut the wall surfaces, and which is arranged to avoid interference with a trim material arranged in the inside corner, cover a through hole formed in the first wall surface and the wiring and piping material pulled out from the through hole, and store the wiring and piping material inside and connect to a straight protective cover arranged in the inside corner.

[0003] In order to arrange the accessory protective cover while avoiding interference with the trim material placed in the inside corner portion, the width and height dimensions in the direction perpendicular to the first and second wall surfaces of the trim material are measured, and the corner portion where the first and second end surfaces intersect on the peripheral wall portion of the protective cover is cut out in a rectangular shape according to the above dimensions to form a cutout portion of the same shape.

[0004] However, if the rectangular shape of the cutout does not correspond to the cross-sectional shape of the trim, that is, if at least one of the dimensions is smaller than the actual dimension, it will be impossible to install the attached protective cover, and it will be necessary to re-cut the cutout to increase the missing dimension in the cutout.In addition, if either of the dimensions of the cutout is significantly larger than the actual dimension, it will be possible to install the attached protective cover, but there will be a problem of a large gap between it and the trim, which will make it look unsightly.

[0005] Furthermore, measuring the height and width of trim pieces placed in narrow corners of building walls is a tedious task, and it is difficult to measure accurately, which causes the above-mentioned problems. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-323432 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention aims to cut out a rectangular cutout area at the corner of a peripheral wall to avoid interference with trim material placed at the inside corner of a building wall, and to accurately identify and cut out the rectangular shape of the cutout area in an attached protective cover placed at the inside corner. [Means for solving the problem]

[0008] The invention of claim 1 to solve the above problem is: An inside corner of a building wall is formed by first and second wall surfaces that are orthogonal to each other, and the building wall has a peripheral wall portion having first and second end faces that abut against both of the wall surfaces, and the protective cover is an accessory for wiring and piping materials that are arranged in the inside corner while avoiding interference with a trim material arranged in the inside corner, On the inner surface of the cutting region of the corner where the first and second end faces of the peripheral wall portion intersect, a plurality of linear groove-shaped cutting position indicators are formed parallel to the first end face at predetermined intervals along the longitudinal direction of the second end face so that the corner can be cut off at a position corresponding to a first dimension in a direction perpendicular to the first wall face of the trimming material, and a plurality of cutting position indicators are formed in the cutting region of the corner at predetermined intervals along the longitudinal direction of the first end face as indicators for cutting off the corner at a position corresponding to a second dimension in a direction perpendicular to the second wall face of the trimming material, This configuration is characterized in that the corner can be cut into a square shape by selecting a specific cutting position indicator portion corresponding to the first dimension of the trim from among the multiple cutting position indicator portions formed on the corner, and determining the cutting position using a specific cutting position indicator portion corresponding to the second dimension of the trim from among the multiple cutting position indicator portions formed on the corner as an indicator.

[0009] In the invention of claim 1, the first and second dimensions perpendicular to the first and second wall surfaces of the parting material placed in the inside corner (the dimensions relating to the height and width of the parting material when the first wall surface is used as the reference) are measured, and a specific cutting position indicator corresponding to the specific first dimension related to the measurement is selected from among the multiple cutting position indicators and cutting position indicators formed on the corner of the peripheral wall of the attached protective cover, and the specific cutting position indicator corresponding to the specific second dimension is used as an indicator to determine the cutting position, and the corner is cut away in a square shape. This makes it possible to arrange the attached protective cover in the inside corner without interference with the parting material placed in the inside corner, and without creating a large gap between the parting material and the square cut-out portion of the side wall. As a result, the corners of the peripheral wall of the attached protective cover can be accurately cut off in accordance with the height and width dimensions of the trim, and since the cutting position indicator is a linear groove, not only is it easy to cut off the corners, but there is no large gap between the trim and the square cut-out portion of the side wall, so the appearance of the trim is also good. Note that the first and second dimensions of a trim placed in an inside corner can be measured quickly and accurately by using the "method for arranging an attached protective cover for an inside corner" of the invention according to claim 7 described below.

[0010] The invention of claim 2 is the invention of claim 1, the cutting position indicator portion is composed of a stepped surface portion formed by a change in thickness of the peripheral wall portion in the cutting region, The cut-out area is characterized in that, in the extension direction of the cutting position indicator portion, the side of the second end face of the peripheral wall portion is thinner than the step surface portion, and the opposite side across the step surface portion is thicker.

[0011] According to the invention of claim 2, when cutting the corner of the accessory protective cover at a predetermined cutting position by indexing a specific cutting position indicator portion corresponding to the second dimension, cutting is made easier by cutting on the thinner side of the stepped cutting position indicator portion, and when the mold is separated after injection molding, there is no raised portion in the separation direction that would hinder the separation, so there is no need for a sliding piece (a sliding mold that slides in a different direction from the mold for the main body) to mold the cutting position indicator portion at the corner, making mold molding easier.

[0012] The invention of claim 3 is the invention of claim 1, The cutting position display portion and the cutting position indicator portion are formed only on the inner surface of the peripheral wall portion.

[0013] According to the invention of claim 3, since neither the cutting position display portion nor the cutting position indicator portion can be seen from the outside of the attached protective cover, the appearance of the outer surface of the peripheral wall portion is not impaired, and the aesthetic appearance can be maintained as is.

[0014] The invention of claim 4 is the invention of claim 2, The cutting position display portion and the cutting position indicator portion are formed only on the inner surface of the peripheral wall portion.

[0015] According to the invention of claim 4, the same effects as those of the invention of claim 3 are achieved.

[0016] The invention of claim 5 is any of the inventions of claims 1 to 4, The plurality of cutting position indicators are formed to have equal lengths, The smaller the second dimension, the more the multiple cutting position indicator portions are partially formed between the cutting position display portions closer to the first end face of the peripheral wall portion, and the larger the second dimension, the more the multiple cutting position indicator portions are partially formed between the cutting position display portions farther from the first end face of the peripheral wall portion, or the relationship between the size of the second dimension and the distance from the first end face to the formation position between adjacent cutting position display portions where the cutting position indicator portions are formed is reversed to the above, and all cutting position indicator portions are formed in a stepped shape.

[0017] According to the invention of claim 5, the multiple cutting position indicator portions are formed in a stepped manner between the cutting position display portions, making it easy to visually grasp the location of a specific cutting position indicator portion, so that the specific cutting position indicator portion corresponding to the second dimension of the trim material can be selected without error.

[0018] The invention of claim 6 is the invention of claim 5, The cutting position display portion and the cutting position indicator portion are characterized in that they are formed adjacent to each other alternately along a direction perpendicular to the groove formation direction of the cutting position display portion.

[0019] According to the invention of claim 6, the cutting position indicator portion is arranged between the linear groove-shaped cutting position display portions and can be recognized by standing out from the grooves on both sides, so that a specific cutting position indicator portion can be selected without error.

[0020] The invention of claim 7 is as follows: A method for arranging the protective cover attached to the wiring and piping material according to any one of claims 1 to 4 at the inside corner, comprising: a first mark is placed by abutting the peripheral wall portion of the attached protective cover against the parting material with a first end face of the peripheral wall portion against a first wall surface, selecting one of the plurality of cutting position indicating portions formed in the cut-out area that corresponds to a first dimension of the parting material, and placing a first mark; and abutting the peripheral wall portion of the attached protective cover against the parting material with a second end face of the peripheral wall portion of the attached protective cover against a second wall surface, selecting one of the plurality of cutting position indicator portions formed in the cut-out area that corresponds to a second dimension of the parting material as an indicator to determine a cutting position and place a second mark; The method is characterized in that the first and second perpendicular marks are used to cut out the cutting area in a square shape, and the attached protective cover is positioned in the inside corner portion while avoiding interference with the trim material.

[0021] According to the invention of claim 7, the first and second dimensions (height and width dimensions) of the trim material placed in the inside corner can be reliably and easily measured, and the corresponding first and second cutting position indicators can be selected and marked without error from among a plurality of first and second cutting position indicators, thereby facilitating the work of cutting the corners of the peripheral wall portion of the attached protective cover into a square shape corresponding to the cross-sectional shape of the trim material. [Effects of the Invention]

[0022] In order to avoid interference with trim materials placed at the inside corners of a building wall, the present invention involves cutting out the cut-out area at the corner of the peripheral wall in a square shape, and in the attached protective cover placed at the inside corner, a cut-out area is formed at the corner, equipped with a plurality of cutting position display portions and cutting position indicator portions corresponding to the first and second dimensions of various types of trim materials.By selecting a specific cutting position display portion corresponding to the first dimension of a specific trim material and determining the cutting position using the specific cutting position indicator portion corresponding to the second dimension of the trim material as an indicator, the cut-out area formed at the corner can be cut out into an accurate square shape corresponding to the cross-sectional shape of the trim material.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention will be described in more detail below with reference to several preferred embodiments. [Example]

[0025] First, an attached protective cover C1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 4. As shown in Figures 1 to 3, the attached protective cover C1 is disposed in an inside corner W0 of a building wall where a parting material F1 is disposed, so as to be connectable to one end of a conduit P disposed perpendicularly to a side wall surface W2, which is the other second wall surface constituting the inside corner W0, in order to conceal and accommodate an exposed portion of a cable K drawn out from a ceiling wall surface W1, which is one of the first wall surfaces constituting the inside corner W0, while avoiding interference with the parting material F1, and is formed by injection molding of resin using a molding die. The accessory protective cover C1 for this purpose has first and second openings 1 and 2 formed on the side of the building wall that constitutes the inside corner W0, facing the ceiling wall W1 and side wall W2 that are perpendicular to each other, and includes an inside corner arrangement portion A having a U-shaped cross section that is arranged between both the ceiling wall W1 and the side wall W2, an irregular saddle-shaped conduit connection portion B that is connected in an externally fitted state to one end of the conduit P that is arranged vertically along the side wall W2, and The corner arrangement portion A has a first end face 3 that is U-shaped in plan view and abuts against the ceiling wall surface W1, and the corner arrangement portion A, the irregularly shaped connection portion E, and the conduit connection portion B have a pair of second end faces 4 that are curved and linear in side view and perpendicular to the first end face 3, separated by the second opening face 2. The second end face 4, which is continuous in a curved and linear shape, is formed with a total of three linear end faces 4a, 4e, and 4b connected via bends.

[0026] The inside corner arrangement portion A comprises a pair of parallel first peripheral wall portions 5 arranged perpendicular to the inside corner portion W0, and a second peripheral wall portion 6 connecting the ends of the pair of first peripheral wall portions 5 opposite the second opening surface 2. The portion of the attached protective cover C1 that interferes with the parting material F1 arranged at the inside corner portion W0 is a corner portion 7 where the first end face 3 and the linear end face 4a constituting the second end face 4 of the inside corner arrangement portion A intersect. This corner portion 7 is provided with a rectangular cutout portion 8 (see Figures 6 and 7) that is cut out to correspond to the cross-sectional shapes of various parting materials F1, thereby avoiding interference with various parting materials F1. The size of the square cutout portion 8 varies depending on the cross-sectional shapes of the various parting materials F1, and a specific portion of the corner portion 7 forms a rectangular cutout area G1.

[0027] Regarding the dimensions of the cross section of the trim F1 placed in the inside corner W0, as shown in Figure 4, the dimension perpendicular to the ceiling wall W1 is defined as the first dimension L1, and the dimension perpendicular to the side wall W2 (parallel to the ceiling wall W1) is defined as the second dimension L2. That is, the height and width of the trim F1 are inversely related to each other depending on whether the ceiling wall W1 or the side wall W2 is selected as the reference. Therefore, to avoid misunderstandings and ensure generality, the expressions "first and second dimensions L1" and "L2" are adopted. Note that the cross section of the trim F1 is not limited to a rectangular shape, and other shapes are also contemplated, and the above-mentioned dimensional definitions are applicable even to shapes other than a rectangular shape.

[0028] On the inner surface of the cutout region G1 of the corner portion 7 of the pair of first peripheral wall portions 5 constituting the inside corner arrangement portion A of the accessory protective cover C1, a plurality of linear groove-like cutout position indication portions D are formed parallel to the first end face 3 at regular intervals along the longitudinal direction of the linear end face 4a of the second end face 4. 11 and adjacent cutting position display portions D at predetermined intervals along the longitudinal direction of the first end surface 3. 11 A plurality of cutting position indicators D are formed in a stepped surface shape by changing the thickness along the longitudinal direction of the first end surface 3 between the first end surface 3 and the cutting position indicators D. 12 The cutting position indicator D is a straight groove.11 indicates the position at which the resection area G1 is cut at a position corresponding to the first dimension L1. 12 is an indicator for determining an approximate position corresponding to the second dimension L2, and the specific cutting position is indicated by the cutting position indicator D 12 In some cases, the cutting position indicator D 12 The cutting position indicator D is in the form of multiple linear grooves. 11 are all of equal length, the overall shape of the excision region G1 is rectangular, and the plurality of cutting position indicators D 12 The smaller the second dimension L2, the closer the cutting position indication portion D to the first end surface 3 of the first peripheral wall portion 5. 11 As the second dimension L2 increases, the cutting position indication portion D on the side farther from the first end surface 3 of the first peripheral wall portion 5 is formed in a stepped surface shape. 11 The cutting region G1 is formed in a stepped shape by being partially formed between the cutting position indicator D 11 In the forming direction of the cutting position indicator portion D 12 The side of the straight end face 4a constituting the second end face 4 of the first peripheral wall portion 5 is thinner than the side of the cutting position indicator portion D 12 In this way, the thickness of the first peripheral wall portion 5 including the cutting region G1 is changed, and the cutting position indicator portion D 12 and a plurality of cutting position indicator portions D 12 is formed in the stepped shape as described above, and a considerable portion of the resection area G1 is thinned, which makes it easier to cut the resection area G1 using a cutting tool 42 (see Figures 6 and 7) to form the square resection portion 8.

[0029] Furthermore, when molding the inside corner arrangement portion A including the cut-out region G1 in the injection molding of resin using a mold, there is no protruding portion that hinders the separation of the mold in the separation direction, i.e., there is no undercut portion adjacent to the protruding portion in the separation direction of the mold, so the cutting position indicator portion D is not provided in the cut-out region G1. 12 Another advantage is that the slide pieces for molding the mold are no longer necessary, simplifying the mold structure.

[0030] The conduit connection portion B of the attached protective cover C1 is connected in a saddle-fitted state to the upper portion of the conduit P, which is disposed perpendicular to the side wall surface W2, which is the second wall surface. That is, the conduit connection portion B has a roughly U-shape in cross section, and in order to maintain the fitted state around the conduit P without coming off the conduit P, the side of the straight end surface 4a constituting the second end surface 4 of the attached protective cover C1 is formed to be thicker than other portions, and the thickness gradually decreases from the side of the straight end surface 4a toward the uniform thickness portion in correspondence with the circular cross section of the conduit P, and by connecting to the uniform thickness portion, the cross section of the inner peripheral surface is formed into a circle with a central angle θ of approximately 270° (see FIGS. 2(d) and (e)), and can be fitted around the circular cross section of the conduit P. That is, the conduit connection part B is composed of a semi-short cylindrical covering part 11 with a uniform thickness that covers approximately half of the cross section of the conduit P, and a pair of locking parts 12 that extend linearly from both ends of the covering part 11 and have a gradually thicker inner wall than the covering part 11, thereby performing a locking function to maintain the conduit P fitted over the conduit. The pair of thick-walled locking parts 12 have recessed parts 13 that open into the linear end faces 4b to prevent sink marks from occurring during resin injection molding. The conduit connection part B and the inside corner arrangement part A are connected to each other by a special-shaped connecting part E to form a pair of second end faces 4 that are arranged on the same plane, thereby forming an accessory protective cover C1.

[0031] 4, 5, and 8, a through hole 41 for pulling out a cable K is formed in the ceiling wall W1, which is the first wall, and the cable K pulled out from the through hole 41 is inserted into and accommodated in a conduit P arranged vertically on the side wall W2, which is the second wall, so that the portion of the cable K between the through hole 41 and the upper end of the conduit P is exposed, and the exposed portion of the cable K is covered with an attached protective cover C1, which is arranged to avoid interference with a parting material F1 arranged in the inside corner W0, by performing the following operations in the following order: The conduit P is arranged vertically and fixed to the side wall W2 via a plurality of saddles having an external fitting structure.

[0032] First, as shown in FIG. 4, in a state where the first end surface 3 of the inside corner arrangement portion A of the accessory protective cover C1 is abutted against the ceiling wall surface W1, which is the first wall surface, one of the first peripheral wall portions 5 of the inside corner arrangement portion A is abutted against the parting material F1, and the first dimension (height) L1 of the parting material F1 is determined, and the plurality of cutting position indication portions D 11 A specific cutting position display section D 11 5, the second end surface 4 of the accessory protective cover C1 is brought into contact with the side wall surface W2, which is the second wall surface, and one of the first peripheral wall portions 5 of the inside corner arrangement portion A is brought into contact with the parting material F1, the second dimension (width) L2 of the parting material F1 is determined, and the plurality of cutting position indicators D are attached to the parting material F1. 12 A specific cutting position indicator D 12 is selected and a second cutting line indication S2 (see FIG. 6) is attached to it.

[0033] Through the above steps, the first and second dimensions L1, L2, which are the height and width dimensions of the rectangular cross-section of the parting material F1 placed in the inside corner W0, are accurately measured, and the dimensions of the square cutout portion 8 that can be placed without interfering with the parting material F1 are identified. In Figure 6, the first and second cutting line indicators S1, S2 are applied to the cutout area G1 of each first peripheral wall portion 5 of the inside corner arrangement portion A of the attached protective cover C1, and cutting tool 42 is used to cut out the cutout area G1 into a square shape. As shown in Figure 7, square cutout portions 8 are formed in the corners 7 of each first peripheral wall portion 5 of the inside corner arrangement portion A of the attached protective cover C1. In Figure 7, 8' denotes a square cutout piece.

[0034] Then, as shown in Figure 8, a brush 43 is used to apply glue to the inner surface of the conduit connection portion B of the accessory protective cover C1, and then the accessory protective cover C1 is arranged in the recessed corner portion W0 formed by the first and second wall surfaces, the ceiling wall surface W1 and the side wall surface W2.As shown in Figures 9 and 10, the parting material F1 enters each of the square cutout portions 8 formed in each corner portion 7 of the pair of first peripheral wall portions 5 of the recessed corner arrangement portion A, thereby avoiding interference with the parting material F1, and the first and second end faces 3, 4 of the accessory protective cover C1 abut against the ceiling wall surface W1 and the side wall surface W2, respectively, and the exposed portion of the cable K is contained inside the accessory protective cover C1. The conduit connection portion B of the accessory protective cover C1 is elastically deformed outward almost entirely, and then restored to its original shape, so that the pair of locking portions 12 externally fits the upper end of the conduit P arranged perpendicularly to the side wall surface W2 with an locking structure, and the synergistic effect of the locking structure and adhesive adhesion allows the cover to be firmly externally fitted without coming off the upper end of the conduit P. As described above, the square cutout portions 8 formed on each corner portion 7 of the pair of first peripheral wall portions 5 of the inside corner arrangement portion A are cut out after accurately measuring the first and second dimensions L1, L2, which are the height and width of the parting material F1. Therefore, the accessory protective cover C1 can be installed in a single installation operation without interfering with the parting material F1, and no large gap is generated between the square cutout portions 8 and the parting material F1. In addition, when the accessory protective cover C1 is installed, the cutting position indicators D formed in the cutout area G1 11 and each cutting position indicator D 12 is formed on the inner surface of a pair of first peripheral wall portions 5 of the inside corner arrangement portion A and cannot be seen from the outside, so that the arrangement state of the parting material F1 portion of the attached protective cover C1 looks good.

[0035] In the cutting region G1 of each corner 7 of the pair of first peripheral wall portions 5 of the inside corner arrangement portion A, a plurality of cutting position indication portions D are provided corresponding to the cross-sectional shapes of various parting materials F1. 11 and cutting position indicator D 12 are formed, a plurality of cutting position display parts D are formed corresponding to the first and second dimensions L1, L2 of various parting materials F1 having a rectangular cross section and other shapes. 11and a specific one is selected from the plurality of cutting position indicators D 12 By using one of the above as an indicator to determine the cutting position and cutting the corner 7 into a square shape, it is possible to avoid interference with trimming materials F1 of various cross-sectional shapes and to arrange the accessory protective cover C1 at the recessed corner W0 formed at the intersection of the first and second wall surfaces W1, W2 that are perpendicular to each other.

[0036] Next, referring to Figures 11 to 14, the accessory protective covers C2 to C5 of Examples 2 to 5 of the present invention, which have different structures for the cutting position display portion and cutting position indicator portion formed in each resection area G2 to G5, will be described. Parts that are the same as or equivalent to those of Example 1 will be given the same symbols, and only the different parts will be described. [Example]

[0037] The cutting position indicator D formed in the cutting region G2 of the accessory protective cover C2 of the second embodiment shown in FIG. 21 The shape of the cutting position indicator D is the same as that of the first embodiment. 21 There are multiple cutting position indicators D between the two, which are stepped due to the change in thickness. 22 The cutting position indicators D are formed in a stepped shape in the same manner as in the embodiment, but the only difference is the direction in which the cutting position indicators D are arranged in the stepped shape. 22 Contrary to Example 1, the smaller the second dimension (width) of the trim material F1, the further it is formed from the first end face 3 of the inside corner arrangement portion A, and the larger the second dimension (width), the closer it is formed to the first end face 3, so it is arranged in a stepped pattern. [Example]

[0038] In the accessory protective cover C3 of the third embodiment shown in FIG. 12, the entire rectangular cutout area G3 is formed thinner than the other parts, and the plurality of cutting position indicators D of the first and second embodiments are formed in the thin cutout area G3. 11 , D 21 A plurality of linear groove-shaped cutting position display sections D having different lengths corresponding to the 31 By forming the cutting position display part D 31The formed ends of the trim F1 are different in a stepped shape, and each formed end has a cutting position indicator D that indicates the second dimension L2 of the trim F1 (width based on the ceiling wall surface W1). 32 Multiple cutting position indicators D 31 The position of the formed end is the cutting position indicator D of Example 1. 12 The cutout region G3 in Example 3 is formed thinner than the other portions as a whole, which makes it easier to cut when forming the rectangular cutout portion 8. [Example]

[0039] The cutting area G4 of the accessory protective cover C4 of the fourth embodiment shown in FIG. 13 is, contrary to the first embodiment, a plurality of linear groove-shaped cutting position indicators D that determine the cutting position corresponding to the second dimension L2 (width based on the ceiling wall surface W1, which is the first wall surface) of the parting material F1. 41 are formed at regular intervals along the longitudinal direction of the first end face 3 of the inside corner arrangement portion A, along the longitudinal direction of the linear end face 4a constituting the second end face 4, and each cutting position indication portion D 41 A plurality of cutting position indicators D for determining cutting positions corresponding to the first dimension L1 (height based on the ceiling wall surface W1, which is the first wall surface) of the parting material F1 are provided between the 42 are formed on a stepped surface due to a difference in thickness and arranged in a stepped pattern. [Example]

[0040] The cut-out area G5 of the accessory protective cover C5 of the fifth embodiment shown in FIG. 14 is formed by forming the entire rectangular cut-out area G5 thinner than the other parts, and forming a plurality of vertical and horizontal cutting position indication portions D 51 or cutting position indicator D 52 These are arranged perpendicular to each other to form a lattice-like structure as a whole. [Example]

[0041] While each of the accessory protective covers C1 to C5 of Examples 1 to 5 is intended to be used alone at an inside corner W0 of a building wall, the accessory protective cover C6 of Example 6 shown in Fig. 15 differs from the accessory protective covers C1 to C5 in two respects: it is made up of a base V6 and a lid body U6 and is used by connecting it to a straight protective cover C0 arranged at the inside corner W0, and it has a base V6 assembled integrally with the lid body U6. The accessory protective cover C6 is used by connecting it to the straight protective cover C0 arranged at the inside corner W0 to house and protect the bent portion of the piping material 44 housed and protected by the straight protective cover C0, and it is made up of a base V6 that is L-shaped in plan view and fixedly arranged at the inside corner W0, and a lid body U6 of the same shape that is assembled integrally with the base V6. A trim material F2 is placed in the inside corner W0, and the base V0 of the linear protective cover C0 and the base V6 of the attached protective cover C6 are both chamfered at the portions placed in the inside corner W0 so that they can be placed without interfering with the trim material F2.

[0042] The cover body U6 of the accessory protective cover C6 is L-shaped in a plan view and comprises a single-walled peripheral wall portion 21a disposed at the inside corner W0 and a pair of opposing peripheral wall portions 21b, 21c disposed at the side wall surface W2. A cutout region G6 is formed on the inner surface of a corner portion 22 disposed at the inside corner W0 of the peripheral wall portion 21b, and a cutting position indicator D identical to that of Example 4 is formed in the cutout region G6. 41 and cutting position indicator part D of Example 4 42A cutting position indicator (not shown) is formed by reversing the stepped arrangement of the cutout portion G6. Therefore, the cutout region G6 is cut out to form a rectangular cutout portion 23 corresponding to the cross-sectional shape of the parting trim F2. In this state, when the cover U6 is pressed against the base V6 disposed in the inside corner W0, the cover U6 is integrally assembled to the base V6 through an engaging structure, as shown in Figure 15(b). The piping material 44, which is installed horizontally in the inside corner W0, and the piping material 44, which is installed vertically on the side wall W2, are connected by an elbow 45, and the elbow 45 is housed and held in the accessory protective cover C6. The straight protective cover connected to the cover U6 of the accessory protective cover C6 at the side wall W2 is not shown in Figure 15. In Figure 15, 23' denotes a rectangular cutout piece.

[0043] In addition to the above-described embodiment, the "cutting position indicator" may be formed by a visible protrusion or by coloring. [Explanation of symbols]
