  However, in a configuration in which a plurality of support brackets are provided at predetermined intervals, it is necessary to arrange the support brackets linearly in a state of being separated from each other, and the work of attaching the support brackets to the wall portion is difficult. It will be high. For example, when the mounting height position varies from one support bracket to another, there is a concern that the design of the wall portion may deteriorate due to distortion or unevenness in the cove forming portion.

  This invention is made | formed in view of the said situation, and provides the interior structure of the building which can make the designability regarding a wall part suitable in the structure by which the cove is provided with respect to the wall part. This is the main purpose.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  An interior structure of a building according to a first aspect of the present invention includes a cove forming portion that forms a cove that is open upward or downward in a building and a wall portion, and the cove forming portion projects from the wall portion. In this state, the cove frame extending in the longitudinal direction of the wall width direction of the wall portion, and fixed to the upper surface portion and the lower surface portion of the cove frame in a state of extending along the longitudinal direction of the cove frame, A pair of mounting plate portions provided so as to extend from the wall surface of the wall portion, and provided on the opposite side of the wall portion across the cove, in a state extending along the longitudinal direction of the cove frame A curtain plate portion fixed to the cove frame, the cove frame having a first square member fixed to the wall portion with the wall width direction as a longitudinal direction, and a wall surface of the wall portion Wall thickness orthogonal to And a second square member whose one end is fixed to the first square member with a direction as a longitudinal direction, and a plurality of the second square members are arranged at predetermined intervals along the longitudinal direction of the first square member. It is characterized by.

  According to the first invention, in the cove frame, since the plurality of second square members are fixed to the first square member, the first square member and the second square member are not individually attached to the wall portion. By attaching the cove frame to the wall portion, the first square member and the second square member can be attached to the wall portion collectively. Here, at the stage of manufacturing the cove frame, it is relatively easy to linearly arrange a plurality of second square members along the first square member. Therefore, the second square member is attached with the cove frame attached to the wall. It is possible to suppress the mounting height position from varying. In this case, in the mounting plate portion and curtain plate portion attached to the cove frame, distortion and unevenness are less likely to occur in the respective plate thickness directions, and as a result, the design of the wall portion to which the cove forming portion is attached. The property can be made suitable.

  Since the cove frame can be manufactured by combining a plurality of general-purpose members such as simple square members instead of specially processed special members, the cost burden when constructing the cove forming portion can be reduced.

  In a second invention, in the first invention, in the cove frame, each upper surface and each lower surface of the first square member and the second square member form the upper surface portion and the lower surface portion, and the pair An upper upper plate portion of the mounting plate portion is fixed to each upper surface of the first square member and the second square member, and a lower lower plate portion is fixed to the first square member and the second square member. It is being fixed to each of each undersurface.

  In the cove frame in which a plurality of second square bars are fixed to the first square bar, even if the first square bar is firmly fixed to the wall, a load is applied to the second square bar to cause a second against the first square bar. There is a concern that the connection of the square bars will be released. On the other hand, according to the second invention, since the pair of mounting plate portions straddle the boundary portion between the first square member and the second square member, the load from these mounting plate portions is the first. It is not added to only one of the first square bar and the second square bar, but is added to both the first square bar and the second square bar. In addition, since each mounting plate portion is fixed to each of the first square member and the second square member, the fixing strength between the first square member and the second square member is enhanced by these mounting plate portions. As described above, the support strength of the cove frame manufactured by combining a plurality of square members can be increased.

  In a third invention, in the second invention, the cove forming portion is provided in a state of being stretched over each second square member on the opposite side of the first square member with the plurality of second square members interposed therebetween. A third square member, the third square member is fixed to each tip of the plurality of second square members, and the upper plate portion is provided on each upper surface of the first square member and the second square member. In addition, it is fixed to the upper surface of the third square bar, and the lower plate portion is fixed to the lower surface of the third square bar in addition to the lower surfaces of the first square bar and the second square bar.

  In a cove frame in which one end of the second square bar is fixed to the first square bar, there is a concern that the height position of the tip of each second square bar (the end opposite to the first square bar) varies. On the other hand, according to the third invention, since the tips of the plurality of second square bars are fixed to the third square bars, the tips of the second square bars are linearly arranged along the third square bars. can do. For this reason, it can suppress more reliably that a distortion and unevenness arise in a cove formation part.

  According to a fourth invention, in any one of the first to third inventions, a fixing tool that penetrates the first square bar and is driven into the wall portion is provided at a height position near the upper end of the first square bar. An upper fixing tool and a lower fixing tool provided at a position lower than the upper fixing tool, and the upper fixing tool and the lower fixing tool are respectively arranged at predetermined intervals along the wall width direction. A plurality of lower fixtures are arranged side by side, and each lower fixture is arranged between the adjacent upper fixtures.

  According to the fourth invention, in the configuration in which the upper fixing tool and the lower fixing tool penetrate the first square member and are driven into the wall portion, the upper fixing tool and the lower fixing tool are arranged in a staggered manner. Therefore, the number of the upper fixing tool and the lower fixing tool can be reduced as compared with the configuration in which the upper fixing tool and the lower fixing tool are driven in positions vertically aligned. In this case, it is possible to reduce the cost burden and work burden of fixing the first square member after increasing the fixing strength of the first square member to the wall portion by driving the fixture into the first square member in two steps.

  According to a fifth invention, in any one of the first to fourth inventions, the pair of mounting plate portions are provided side by side along the wall width direction, and the curtain plate portion has the wall width. A plurality of curtain plates are formed side by side along the direction, and the cove frame is provided side by side along the wall width direction.

  The cove forming part 23 has a plurality of parts such as a pair of plate parts 41 and 42, a curtain plate part 43a, a cove base part 44, and a counter plate part 58, and the same parts are in the wall width direction. A plurality are provided side by side. Here, the connection configuration of adjacent cove foundation portions 44 will be described with reference to FIGS.

  FIG. 5 is a view showing the arrangement of the plurality of cove foundation portions 44, FIG. 6 is a view showing the boundary between the cove foundation portions 44, and FIG. 7 is a perspective view showing the configuration of the cove forming portion 23. 5A is a plan view of each cove ground portion 44, FIG. 5B is a plan view around the cove ground portion 44 and the corner corner ground portion 61, and FIG. In addition to the portions 44 and 61, a counter plate portion 58 and a curtain plate portion 43a are shown. 6A is a cross-sectional view taken along the line CC of FIG. 5A, FIG. 6B is a front view of the cove forming portion 23, and FIG. A pair of plate portions 41 and 42 are shown. 7A is a perspective view of the wall-side cross member 51 and the connecting member 53, and FIG. 7B is a perspective view of the cove forming portion 23. FIG.

  As shown in FIG. 5A, the plurality of cove base portions 44 are arranged in series along the wall width direction of the wall portion 12, and each cove base portion 44 extends along the wall width direction. It has a horizontally long shape. In each cove foundation 44, the lengths of the wall-side cross member 51 and the room-side cross member 52 in the wall width direction are the same. And the boundary part of each room side cross member 52 overlap in the wall thickness direction. Further, in the cove foundation portion 44, the connecting member 53 is disposed at a position that does not protrude from the cross members 51, 52 in the wall width direction.

  Similarly to the cove foundation portion 44, a plurality of upper plate portions 41, lower plate portions 42, curtain plate portions 43a and counter plate portions 58 are arranged along the width direction of the wall portion 12, and each upper plate portion 41, Each lower plate portion 42, each curtain plate portion 43a, and each opposing plate portion 58 have a horizontally long shape extending along the wall width direction. Further, the upper plate portion 41, the lower plate portion 42, the curtain plate portion 43a, and the opposing plate portion 58 have the same length dimension in the wall width direction as the cove foundation portion 44. Here, the boundary portion between the upper plate portions 41 and the boundary portion between the opposing plate portions 58 coincide with the boundary portion between the cove foundation portions 44 in the wall width direction, while the boundary portion between the lower plate portions 42. And the boundary portion between the curtain plate portions 43a do not coincide with the boundary portion between the cove foundation portions 44 in the wall width direction. That is, the boundary part between the decorative face materials does not coincide with the boundary part between the cove foundation parts 44 in the wall width direction.

  As shown in FIGS. 6A, 6B, and 7A, the boundary portion N2 between the lower plate portions 42 is one side in the wall width direction with respect to the boundary portion N1 between the cove foundation portions 44. The boundary portion N3 between the curtain plate portions 43a is shifted to the opposite side of the boundary portion N2 between the lower plate portions 42 with the boundary portion N1 between the cove base portions 44 interposed therebetween. In this case, the boundary portion N2 between the lower plate portions 42 and the boundary portion N3 between the curtain plate portions 43a do not coincide with each other in the wall width direction, and the lower plate portion 42 and the curtain plate portion 43a are the cove foundation portion 44. The boundary portion N1 is covered with the outside of the cove forming portion 23 (the side opposite to the cove 21). In this case, in the boundary portion N1 between the adjacent cove base portions 44, the formation of a step or a gap between the cove base portions 44 is suppressed by the lower plate portion 42 and the curtain plate portion 43a. Even so, the steps and gaps can be covered by the lower plate portion 42 and the curtain plate portion 43a.

  The boundary portion N1 between the cove foundation portions 44 is disposed between the boundary portion N2 between the lower plate portions 42 and the boundary portion N3 between the curtain plate portions 43a. In this case, the positional deviation of the lower plate portion 42 with respect to the cove base portion 44 and the positional deviation of the curtain plate portion 43a are opposite in the wall width direction. For this reason, for example, when a step or gap occurs in one of the boundary portion N2 between the lower plate portions 42 and the boundary portion N3 between the curtain plate portions 43a, the other is caused by the occurrence of the step or gap. It can suppress that a level | step difference and a clearance gap generate | occur | produce.

  The lower plate portion 42 is fixed to each of the two cove foundation portions 44 over which the lower plate portion 42 straddles with screws or the like. Further, the curtain plate portion 43a is fixed by screws or the like to each of the two cove foundation portions 44 and the opposing plate portion 58 that the curtain plate portion 43a straddles.

  The positional deviation of the lower plate portion 42 with respect to the cove base portion 44 and the positional deviation of the curtain plate portion 43a in the wall width direction are the same. In this case, the separation distance L1 between the boundary portion N1 between the cove base portions 44 and the boundary portion N2 between the lower plate portions 42 is between the boundary portion N1 between the cove base portions 44 and the boundary portion N3 between the curtain plate portions 43a. It is the same as the separation distance L2 (L1 = L2).

  In the cove foundation portion 44, the plurality of connecting members 53 include connecting members 53 a that are arranged at positions that vertically overlap the boundary portion N <b> 2 between the lower plate portions 42. The connecting member 53 a is in a state of straddling the boundary portion N <b> 2 between the lower plate portions 42 in the wall width direction, and the lower surface thereof is overlaid on the upper surface of each lower plate portion 42. In this case, both of the adjacent lower plate portions 42 are fixed to the connecting member 53a with screws or the like.

  As shown in FIGS. 6 (a) and 7 (b), a plurality of screws 55 and 56 fixing the wall-side cross member 51 of the cove foundation 44 to the wall 12 are struck along the wall width direction. It has been. In this case, the distance D1 (for example, 30 cm) between the upper screws 55 is the same as the distance D2 (for example, 30 cm) between the lower screws 56. Further, the upper screw 55 is arranged at a position that does not overlap with the lower screw 56 in the vertical direction, and the arrangement of the upper screw 55 and the lower screw 56 is staggered. In this case, the upper screw 55 is disposed in the middle of the adjacent lower screws 56, and the separation distance D3 (for example, 15 cm) between the upper screws 55 and the lower screws 56 is the separation distance D1 ( This is half of the distance D2) between the lower screws 56 (D1 = D2 = D3 × 2).

  In the vertical direction, the separation distance H1 (for example, 25 mm) between the upper screw 55 and the lower screw 56 is about half of the height dimension H2 (for example, 55 mm) of the wall-side cross member 51. Further, the separation distance H3 (for example, 10 mm) of the upper screw 55 from the upper end of the wall-side cross member 51 is made smaller than the separation distance H4 (for example, 20 mm) of the lower screw 56 from the lower end of the wall-side cross member 51. Yes.

  At the boundary portion between the cove foundation portions 44, the end surfaces of the upper plate portion 41 and the lower plate portion 42 are overlapped, and the side surfaces of the respective connecting members 53 are overlapped. In this case, the connecting members 53 whose side surfaces are overlapped with each other are fixed to each other by the screws 59 being driven from one connecting member 53 to the other connecting member 53.

  Returning to the description of FIG. 5A, in the cove forming portion 23, the plurality of cove base portions 44 extend along the first inner wall surface 12 a among the two inner wall surfaces 12 a and 12 b that are orthogonal to each other in the wall portion 12. The first cove base portion 44a and the second cove base portion 44b extending along the second inner wall surface 12b are included. The cove forming portion 23 has a corner corner base portion 61 provided at a corner portion of the wall portion 12, and the corner corner base portion 61 includes a first cove ground portion 44a and a second cove ground portion 44b. Are connected.

  The corner corner base 61 includes a first connection part 61a connected to the first cove base part 44a, a second connection part 61b connected to the second cove base part 44b, and the connection parts 61a and 61b. And an intermediate connection portion 61c provided. In the corner base portion 61, the first connection portion 61a and the second connection portion 61b extend from the intermediate connection portion 61c in a direction orthogonal to each other, and are formed in an L shape as a whole.

  As shown in FIG. 5B, each of the connection portions 61 a to 61 c has substantially the same configuration as the cove foundation portion 44. Each of the connecting portions 61 a to 61 c includes a wall side cross member 51, a room side cross member 52, and a connecting member 53. The first connection portion 61a is disposed in series with the first cove ground portion 44a, and the second connection portion 61b and the intermediate connection portion 61c are disposed in series with the second cove ground portion 44b. In this case, in the second connection part 61b and the intermediate connection part 61c, the respective cross members 51 and 52 are arranged side by side, and the respective connecting members 53 are arranged in parallel.

  Here, the wall-side cross member 51 of the second connection portion 61b and the wall-side cross member 51 of the intermediate connection portion 61c are formed of one member, and among these members, the side of the second connection portion 61b on the side of the room. The portion facing the material 52 corresponds to the wall-side cross member 51 of the second connection portion 61b, and the portion facing the room side cross member 52 of the intermediate connection portion 61c corresponds to the wall-side cross member 51 of the intermediate connection portion 61c. . In addition, in the intermediate connection part 61c, the connection member 53 arrange | positioned on the opposite side to the 2nd connection part 61b is extended along the 1st inner wall surface 12a, and with respect to the 1st inner wall surface 12a in that state It is fixed. The connecting member 53 is arranged in series with the wall-side cross member 51 of the first connecting portion 61a.

  In the 1st connection part 61a, the wall side crosspiece 51 protrudes in the intermediate connection part 61c side rather than the room side crosspiece 52, and the end surface of the room side crosspiece 52 of the intermediate connection part 61c is on the side surface of the protrusion part. It is connected. In addition, in the 1st connection part 61a, the wall side crosspiece 51 does not need to protrude to the intermediate connection part 61c side rather than the room side crosspiece 52, and in this case, the room side crosspiece 52 of the intermediate connection part 61c is It will be in the state which entered between the connection member 53 of the intermediate | middle connection part 61c, and the wall side cross member 51 of the 1st connection part 61a. Moreover, in the corner entry base part 61, the intermediate connection part 61c may be arrange | positioned in series with the 1st cove base part 44a with the 1st connection part 61a.

  In the corner entry base portion 61, a counter plate portion 58 is individually attached to each of the first connection portion 61a and the second connection portion 61b. In the corner portion of the corner corner base portion 61, the end surface of the counter plate portion 58 attached to the second connection portion 61b is superimposed on the plate surface of the counter plate portion 58 attached to the first connection portion 61a. . The winning / losing relationship may be reversed, and the end surface of the opposing plate portion 58 on the first connection portion 61a side may be overlapped with the plate surface of the opposing plate portion 58 on the second connection portion 61b side.

  The boundary between the opposing plate portion 58 attached to the first cove foundation portion 44a and the opposing plate portion 58 attached to the first connecting portion 61a of the corner corner base portion 61 is the first cove foundation in the wall thickness direction. It overlaps the boundary portion N4 between the portion 44a and the corner entry base portion 61. On the other hand, the curtain plate portion 43a attached to the first cove base portion 44a protrudes to the corner corner base portion 61 side from the boundary portion N4, and the protruding portion is fixed to the corner corner base portion 61 by staples or the like. Yes. Although not shown, the lower plate portion 42 attached to the first cove base portion 44a also protrudes toward the corner corner base portion 61 with respect to the boundary portion N4. It is fixed to the part 61.

  In this case, since the curtain plate portion 43a and the lower plate portion 42 are stretched over the first cove base portion 44a and the corner corner base portion 61, the first cove base portion 44a and the first cove base portion 44a Generation of a step or a gap with the corner base portion 61 is suppressed by the curtain plate portion 43a or the lower plate portion 42. Even if a step or a gap is generated, the step or gap is reduced to the curtain plate portion 43a or the gap. The lower plate portion 42 can be covered.

  Similarly, for the boundary portion N5 between the second cove ground portion 44b and the corner corner ground portion 61, the opposing plate portion 58 attached to the second cove ground portion 44b and the second connection portion 61b of the corner corner ground portion 61 are connected. A boundary portion with the attached counter plate portion 58 overlaps the boundary portion N5 in the wall thickness direction. On the other hand, the curtain plate portion 43a attached to the second cove base portion 44b protrudes to the corner corner base portion 61 side from the boundary portion N5, and the protruding portion is fixed to the corner corner base portion 61 by staples or the like. Yes. Although not shown, the lower plate portion 42 attached to the second cove base portion 44b also protrudes toward the corner corner base portion 61 side from the boundary portion N5. It is fixed to the part 61.

  In this case, since the curtain plate portion 43a and the lower plate portion 42 are in a state of being spanned between the second cove base portion 44b and the corner entry base portion 61, the second cove base portion 44b and the second cove base portion 44b Generation of a step or a gap with the corner base portion 61 is suppressed by the curtain plate portion 43a or the lower plate portion 42. Even if a step or a gap is generated, the step or gap is reduced to the curtain plate portion 43a or the gap. The lower plate portion 42 can be covered.

  In the corner portion of the corner corner base portion 61, the curtain plate portion 43a on the first connection portion 61a side (first cove ground portion 44a side) and the second connection portion 61b side (second cove ground portion 44b side). The winning / losing relationship with the curtain plate portion 43a is the same as the winning / losing relationship between the opposing plate portion 58 on the first connecting portion 61a side and the opposing plate portion 58 on the second connecting portion 61b side. In this case, since the end surfaces of the opposing plate portion 58 and the curtain plate portion 43a do not form the same surface on the first connecting portion 61a side or the second connecting portion 61b side, a boundary portion between the opposing plate portions 58 is provided. , The generation of a gap or a step between the opposing plate portions 58 is suppressed by the curtain plate portion 43a. Even if a step or a gap is generated, the step or gap may be covered by the curtain plate portion 43a. it can.

  Although not shown, the corner corner base 61 includes the lower plate portion 42 on the first connection portion 61a side (first cove base portion 44a side) and the second connection portion 61b side (second cove base portion 44b). The lower plate portion 42 is covered from the lower side, and the winning and losing relationship of the lower plate portions 42 is determined by the curtain plate portion 43a on the first connection portion 61a side and the curtain plate portion 43a on the second connection portion 61b side. This is the opposite of the win / loss relationship. In this case, with respect to the corner corner base 61, the direction in which the boundary between the lower plates 42 extends is orthogonal to the direction in which the boundary between the curtain plates 43a extends, so the boundary between the lower plates 42 and When a step or a gap is generated in one of the boundary portions between the curtain plates 43a, it is possible to prevent the step or the gap from being easily generated in the other due to the generation of the step or the gap.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the cove foundation portion 44 (cove frame) is formed including the wall side cross member 51 and the plurality of connecting members 53, the wall side cross member 51 and the connecting member 53 are not individually attached to the wall portion 12. The wall side member 51 and the connecting member 53 can be attached together by attaching the cove foundation portion 44 to the wall portion 12. In particular, by attaching a plurality of connecting members 53 to the wall-side cross member 51 before attaching the wall-side cross member 51 to the wall portion 12, the connecting members 53 are straightened along the wall-side cross member 51. It becomes easy to arrange. Thereby, it can suppress that the height position of the some connection member 53 changes in the state which attached the cove foundation | substrate part 44 to the wall part 12. FIG. In this case, the plate portions 41 and 42 and the curtain plate portion 43a attached to the cove foundation portion 44 are less likely to be distorted or uneven in the plate thickness direction, and as a result, the cove forming portion 23 is attached. The design property of the wall part 12 made can be made suitable.

  In addition, the cove foundation portion 44 is not a specially processed special member, but can be manufactured by combining a plurality of general-purpose members such as the wall-side cross member 51, the room-side cross member 52, and the connecting member 53 formed of simple square members. Moreover, the cost burden at the time of constructing the cove formation part 23 with a wall can be reduced.

  Since the upper plate part 41 and the lower plate part 42 are fixed to each of the wall side cross member 51 and the connecting member 53 in a state of straddling the boundary between the wall side cross member 51 and the connecting member 53, The load applied to the plate portion 41 and the lower plate portion 42 is distributed and applied to both the wall-side cross member 51 and the connecting member 53. For this reason, for example, compared to a configuration in which the pair of plate portions 41, 42 are not fixed to the wall-side cross member 51, when a load is applied to the plate portions 41, 42, the connecting member 53 to the wall-side cross member 51. Is difficult to release. In this case, the wall-side cross member 51 and the connecting member 53 are also indirectly connected via the plate portions 41 and 42 in addition to being directly connected by staples or the like. The fixing strength between the wall-side cross member 51 and the connecting member 53 can be increased. As described above, the support strength of the cove foundation portion 44 manufactured by combining a plurality of square members can be increased.

  In the cove foundation portion 44, the tips of the plurality of connecting members 53 are respectively fixed to the room-side cross member 52, so that the tips can be arranged linearly along the room-side cross member 52. For this reason, it can suppress that the height position of each front-end | tip of the some connection member 53 varies, and the separation distance of these front-end | tips varies. Thereby, in the cove formation part 23, it can suppress more reliably that a distortion and unevenness generate | occur | produce in each board thickness direction about the lower board part 42 and the curtain board part 43a.

  Since the screws 55 and 56 fixing the wall-side cross member 51 to the wall portion 12 are arranged in two steps, when the load is applied to the wall-side cross member 51 in the vertical direction, the wall side The fixed state of the cross member 51 can be suitably maintained. Moreover, since the upper screw 55 and the lower screw 56 are arranged in a staggered manner, the wall-side cross member 51 is fixed to the wall portion 12 as compared with a configuration in which the screws 55 and 56 are arranged side by side. The work burden and the cost burden when doing this can be reduced.

  Since the cove base portions 44 arranged in a plurality along the wall width direction are horizontally long, it is not necessary to separate the cove base portions 44 from each other, and the cove base portions 44 are linearly arranged and fixed to the wall portion 12. Work can be facilitated. In this case, the end portions of the pair of plate portions 41 and 42 and the curtain plate portion 43a do not have to coincide with the end portions of the cove foundation portion 44. Therefore, the plate portions 41 and 42 and the curtain plate portion 43a with respect to the cove foundation portion 44 are used. Can be arbitrarily set in the wall width direction. Thereby, a work burden can be reduced when the plate portions 41 and 42 and the curtain plate portion 43a are attached to the cove foundation portion 44.

  Since the lower plate portion 42 and the curtain plate portion 43a straddle the boundary portion between the cove substrate portions 44, the lower plate portion 42 and the gap between the cove substrate portions 44 are caused by a step and a gap at the boundary portion N1. Even if a step or a gap occurs, the step or gap can be covered by the lower plate part 42 or the curtain plate part 43a. Here, since the lower plate portion 42 is vertically stacked with respect to the cove base portion 44, it is possible to suitably exert a deterrent against the occurrence of a step in the vertical direction at the boundary portion N1 between the cove base portions 44. On the other hand, since the curtain plate portion 43a is overlapped with the cove base portion 44 in the wall thickness direction, it can suitably exert a deterrent against the occurrence of a step in the wall thickness direction at the boundary portion N1 between the cove base portions 44. .

  Since the curtain plate portion 43a straddles the boundary portion N2 between the lower plate portions 42, and the lower plate portion 42 straddles the boundary portion N3 between the curtain plate portions 43a, the lower plate Even if a step or a gap occurs in one of the boundary portion N2 between the portions 42 and the boundary portion N3 between the curtain plate portions 43a, a step or a gap occurs in the other due to the occurrence of the step or the gap. Can be prevented.

  Since the curtain plate portion 43a is fixed to the cove base portion 44 via the counter plate portion 58, the portion protruding upward from the cove base portion 44 in the curtain plate portion 43a can be suitably supported by the counter plate portion 58.

  Since the boundary portion between the upper plate portions 41 and the boundary portion between the opposing plate portions 58 coincide with the boundary portion N1 of the cove base portion 44, the upper plate portion 41 and the counter plate portion 58 are preliminarily formed into the cove base portion 44. In the attached state, the cove foundation portion 44 can be attached to the wall portion 12 together with the upper plate portion 41 and the counter plate portion 58. For this reason, the work man-hour after attaching the cove foundation | substrate part 44 to the wall part 12 can be reduced.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, both the upper screw 55 and the lower screw 56 are driven into the backing material 46, but the target to be driven by these screws 55, 56 may not be the backing material 46. For example, as shown in FIG. 8, a block material 71 is provided on the back side of the inner wall surface material 31, and the upper screw 55 penetrates the inner wall surface material 31 and is driven into the backing material 46. The screws 56 penetrate the inner wall surface material 31 and are driven into the block material 71. The block material 71 is provided between the base horizontal members adjacent to each other on the upper and lower sides in the inner wall base 32, and is fixed to the base cross member with screws or the like while extending along the lower base cross member. Yes.

  The backing material 46 is a medium-weight backing material, and is provided in a state of being spanned between the upper base material and the block material 71. In the above embodiment, a heavyweight backing material is used. A wiring hole 72 communicating with the wiring hole 33 of the inner wall surface material 31 is formed in the backing material 46.

  Here, as described in the above embodiment, when one of the screws 55 and 56 is used for fixing and the other is used for pulling out, the fixing screw of the backing material 46 and the block material 71 is fixed. It can be said that the one that is driven is a fixing screw base, and the one that is pulled out is a drawing screw base. For example, when the lower screw 56 is for fixing and the upper screw 55 is for pulling out, the block material 71 is a fixing screw base, and the backing material 46 is equivalent to a pulling screw base.

  (2) In the above embodiment, in the wall width direction, the positional deviation of the lower plate portion 42 relative to the cove foundation portion 44 and the positional deviation of the curtain plate portion 43a are the same size (L1 = L2). The magnitude of the positional deviation may be different (L1 ≠ L2). Further, the lower plate portion 42 and the curtain plate portion 43a may have the same misalignment direction with respect to the cove foundation portion 44. In this case, the positional deviation of the lower plate portion 42 and the positional deviation of the curtain plate portion 43a may be the same (L1 = L2) or different (L1 ≠ L2).

  (3) In the above embodiment, of the boundary portion between the upper plate portions 41 and the boundary portion N2 between the lower plate portions 42, only the boundary portion N2 between the lower plate portions 42 is the boundary portion N1 between the cove ground portions 44. However, at least one of the boundary portion between the upper plate portions 41 and the boundary portion N2 between the lower plate portions 42 is separated from the boundary portion N1 between the cove foundation portions 44 by a wall. It suffices if they are separated by a predetermined distance in the width direction. For example, the boundary portion between the upper plate portions 41 is separated from the boundary portion N2 between the lower plate portions 42 with the boundary portion N1 between the cove base portions 44 interposed therebetween.

  (4) In the above embodiment, the boundary portion between the opposing plate portions 58 overlaps the boundary portion N1 between the cove base portions 44 in the wall thickness direction, but this boundary portion is a boundary portion between the cove base portions 44. It may be separated from N1 in the wall width direction. Also in this case, it is preferable that the boundary portion between the opposing plate portions 58 is separated from the boundary portion N3 between the curtain plate portions 43a in the wall width direction.

  (5) In the above embodiment, the boundary portion N2 between the lower plate portions 42 and the boundary portion N3 between the curtain plate portions 43a are separated in the wall width direction, but these boundary portions N2 and N3 have a wall width. It does not have to be separated in the direction. That is, they may overlap in the wall thickness direction. However, these boundary portions N2 and N3 are preferably separated from the boundary portion N1 between the cove foundation portions 44 in the wall width direction.

  (6) The boundary portion N1 between the cove foundation portions 44, the boundary portion N2 between the lower plate portions 42, and the boundary portion N3 between the curtain plate portions 43a may not be separated in the wall width direction. That is, they may overlap in the wall thickness direction or the wall height direction.

  (7) The cove foundation portion 44 may not have the room side cross member 52 and the connecting member 53 as long as it has the wall side cross member 51. In this case, it is preferable that the thickness dimension of the wall-side cross member 51 is the same as the thickness dimension of the cove 21 in the wall width direction.

  (8) In the above embodiment, in the wall side cross member 51, the separation distance H3 between the upper end of the wall side cross member 51 and the upper screw 55 is the separation distance H4 between the lower end of the wall side cross member 51 and the lower screw 56. Is smaller (H3 <H4), but may be H3> H4 or H3 = H4.

  (9) In the above embodiment, the cove forming portion 23 is disposed at a height position near the ceiling surface, but may be disposed at a height position near the floor surface. That is, the floor surface may be illuminated by the lighting fixture 22 installed in the cove 21. For example, it is assumed that the cove 21 is opened downward rather than upward. In this configuration, the lower plate portion 42 corresponds to the cove side plate portion disposed on the cove 21 side, and the upper plate portion 41 corresponds to the exposed plate portion disposed on the side opposite to the cove 21. Further, the curtain plate portion 43a protrudes downward from the cove foundation portion 44, and the lighting fixture 22 is installed in a state of entering the cove 21 from below.

  (10) A wall material may not be attached to a portion of the wall portion 12 that faces the curtain plate portion 43a. That is, the inner wall base 32 may be exposed to the cove 21 side. Even in this case, it is possible to prevent the design of the wall portion 12 from being deteriorated by covering the inner wall base 32 with the curtain plate portion 43a.
