Description

[Technical field]

[0001] The present invention relates to a construction method using a spacer member for interior construction work, and to a spacer member for interior construction work. [Background technology]

[0002] 2. Description of the Related Art Brick-like members for interior construction are known which are attached to a concrete surface to fix or support interior materials such as interior wall facings with a specified space between them and the concrete surface (see Patent Document 1).

[0003] Specifically, the brick-like component 100 for interior construction has a rectangular parallelepiped shape as shown in FIG. 7, and has heat insulating properties.

[0004] In construction using this brick-like component 100 for interior work, as shown in FIG. 8, the bottom surface 101 of the brick-like component 100 for interior work is adhered to a concrete wall surface 103 with adhesive 102, and then a spray material such as urethane (spray insulation material) is sprayed onto the wall surface 103 to form an insulation coating 104, and an interior material 105 is attached to a mounting surface 106 of the brick-like component 100 for interior work with screws 107.

[0005] [Patent Document 1] Utility Model Registration No. 3095213 Summary of the Invention [Problem to be solved by the invention]

[0006] In recent years, from the viewpoint of heat insulation and the like in houses and the like, it has become desirable to increase the thickness of the heat insulating coating (sprayed material) 104 formed on the wall surface 103.

[0007] When spraying the spray material, it is important to control the thickness of the spray material; if too much is sprayed (i.e., the spray material is too thick), the material will have to be scraped off when installing the interior material, and if not enough is sprayed (i.e., the spray material is too thin), the desired insulation effect, etc. will not be obtained.

[0008] However, in the above-mentioned spraying work, visibility of the work surface is poor due to gases generated from the spraying material, and since the material is foamed on-site while being sprayed, it is difficult to control (adjust) the thickness of the spraying material.

[0009] Therefore, an object of the present invention is to provide a construction method using a spacer member for interior work that makes it easy to control the thickness of the spraying material during the spraying work, and a spacer member for interior work. [Means for solving the problem]

[0010] The construction method using the spacer member for interior construction of the present invention includes the following steps: a spacer mounting process for mounting a spacer member for interior construction on a wall surface, the spacer member having a surface including a wall mounting surface to be mounted on the wall surface, a member mounting surface disposed at a first distance from the wall mounting surface in a normal direction to the wall mounting surface and to which an interior material or a fixing member for fixing the interior material is attached, and a peripheral surface between the wall mounting surface and the member mounting surface; a spraying step of spraying a spraying material onto the wall surface with the interior work spacer member attached to the wall surface; and a member mounting step of mounting the interior material or a fixing member for fixing the interior material to the member mounting surface of the interior work spacer member, The spacer member for interior construction has an indicator portion on the peripheral surface which indicates a position spaced a second distance from the wall mounting surface in the normal direction, the second interval being smaller than the first interval; In the spraying step, the spray insulation material is sprayed onto the wall surface using the indicator portion as an indicator.

[0011] In this way, by spraying the spray material onto the wall surface using the indicator part of the interior construction spacer member attached to the wall surface as an indicator, it becomes easy to control the thickness of the spray material during the spraying work. That is, since the second interval is smaller than the first interval, spraying the spray material onto the wall surface using the indicator part as an indicator can prevent the spray material from being too thick (overspraying), while spraying the spray material onto the wall surface using the indicator part that indicates the desired position (the position spaced the second interval from the wall mounting surface) as an indicator can also prevent the spray material from being too thin (insufficient spraying).

[0012] In addition, in the above construction method, In the spraying step, the spray material may be sprayed onto the wall surface so that a surface of the spray material after spraying is positioned at the position of the indicator portion.

[0013] According to this configuration, the spray material can be easily obtained with a desired thickness (second interval) from the wall surface.

[0014] In addition, in the above construction method, In the member attaching step, the interior material may be attached to the fixing member after the fixing member is attached.

[0015] By disposing the fixing member between the interior work spacer member and the interior material in this manner, it becomes easier to adjust the distance between the spray material and the interior material.

[0016] In addition, the spacer member for interior construction of the present invention is A spacer member for interior construction, the spacer member having a surface including a wall mounting surface to be mounted on a wall surface, a member mounting surface disposed at a first distance from the wall mounting surface in a normal direction to the wall mounting surface and to which an interior material or a fixing member for fixing the interior material is attached, and a peripheral surface between the wall mounting surface and the member mounting surface, An indicator portion is provided on the peripheral surface, which indicates a position spaced a second distance from the wall mounting surface in the normal direction and serves as an indicator of a thickness of the spray from the wall surface; The second spacing is smaller than the first spacing.

[0017] According to this configuration, the thickness of the spray material can be easily controlled during the spraying work by spraying the material onto the wall surface using the indicator part of the spacer member for interior construction adhered to the wall surface as an indicator. That is, since the second interval is smaller than the first interval, spraying the material onto the wall surface using the indicator part as an indicator can prevent the material sprayed onto the wall surface from being too thick (overspraying), while spraying the material onto the wall surface using the indicator part that indicates the desired position (the position spaced the second distance from the wall mounting surface) as an indicator can prevent the material sprayed onto the wall surface from being too thin (insufficient spraying).

[0018] In addition, in the spacer member for interior construction, The indicator portion may be configured as a protrusion or a recess.

[0019] In this way, by giving the indicator portion a three-dimensional configuration such as a convex or concave portion, it becomes easier for workers to see the indicator portion even at sites where spraying work is being performed (such as indoor sites where there is insufficient light). Effect of the Invention

[0020] As described above, according to the present invention, it is possible to provide a construction direction using a spacer member for interior work that makes it easy to control the thickness of the spraying material when spraying the spraying material, and a spacer member for interior work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0023] The spacer member for interior construction work in this embodiment (hereinafter also simply referred to as "spacer member") is a member used to form a space between a wall surface and an interior material when attaching the interior material to the wall surface.

[0024] The spacer member 1 is a block-shaped member as shown in Figs. 1 to 3, and has a predetermined thermal insulation property. This thermal insulation property is approximately the same as the thermal insulation property (thermal conductivity) of the spray material 6 (in this embodiment, sprayed insulation material: see Fig. 5) sprayed between the wall surface 5A and the interior material 8. The thermal conductivity (thermal insulation property) of the spacer member 1 of this embodiment is, for example, 0.064 W / m·k. The spacer member 1 is also made of a resin foam member such as expanded polystyrene, and the foaming ratio of the foam member constituting the spacer member 1 of this embodiment is 2.2 to 2.3 times.

[0025] Specifically, the spacer member 1 is a member including, on a surface 2, a wall mounting surface 21 that is adhered to a wall surface 5A via an adhesive layer 4, a component mounting surface 22 that is disposed at a first distance α1 from the wall mounting surface 21 in a normal direction to the wall mounting surface 21, and a peripheral surface 23 between the wall mounting surface 21 and the component mounting surface 22. The spacer member 1 of this embodiment is adhered to the wall surface 5A via the adhesive layer 4 that is formed from an adhesive. The adhesive layer 4 may be formed from a material other than an adhesive, such as double-sided tape.

[0026] This spacer member 1 has an index portion 3 that indicates a position on the peripheral surface 23 at a second distance α2 from the wall mounting surface 21 in the normal direction. The second distance α2 from the wall mounting surface 21 to the index portion 3 is smaller than the first distance α1 from the wall mounting surface 21 to the member mounting surface 22. In other words, the second distance α2 is smaller than the first distance α1. In this embodiment, the first distance α1 is 60 mm, and the second distance α2 is 50 mm. Furthermore, the index portion 3 is formed by a convex portion that protrudes from the peripheral surface 23 or a concave portion that is recessed into the peripheral surface 23, and the index portion 3 in this embodiment is formed by a concave portion.

[0027] The spacer member 1 of this embodiment is rectangular when viewed from the normal direction of the wall mounting surface 21. In the following description, the direction in which the long side of the rectangle extends is the X-axis direction of a Cartesian coordinate system, the direction in which the short side of the rectangle extends is the Y-axis direction of the Cartesian coordinate system, and the normal direction of the wall mounting surface 21 is the Z-axis direction of the Cartesian coordinate system.

[0028] The wall mounting surface 21 extends in a plane direction perpendicular to the Z-axis direction and has a plurality of recesses 21a. The wall mounting surface 21 of this embodiment is rectangular when viewed from the Z-axis direction and has a plurality of recesses over the entire area of ​​the wall mounting surface 21. These recesses are formed by embossing. The wall mounting surface 21 of this embodiment is rectangular with a dimension β1 in the X-axis direction of 75 mm and a dimension β2 in the Y-axis direction of 40 mm.

[0029] The component mounting surface 22 is rectangular and extends in a direction perpendicular to the Z-axis direction and is elongated in the X-axis direction. A dimension β4 of the component mounting surface 22 in the Y-axis direction is smaller than a dimension β2 of the wall mounting surface 21 in the Y-axis direction. The component mounting surface 22 in this embodiment is rectangular with a dimension β1 in the X-axis direction of 75 mm and a dimension β3 in the Y-axis direction of 25 mm.

[0030] The peripheral surface 23 is composed of two pairs of opposing surfaces 231, 232. Specifically, the peripheral surface 23 is composed of a pair of first opposing surfaces 231 opposing in the X-axis direction and a pair of second opposing surfaces 232 opposing in the Y-axis direction.

[0031] The first opposing surface 231 is a rectangular shape that is long in the Z-axis direction, with both corners on one side in the Z-axis direction (the component mounting surface 22 side) cut out in an L-shape, and in the spacer member 1, this cut-out portion (cutout portion) extends in the X-axis direction to form the indicator portion 3. The dimension β4 of this cut-out portion (indicator portion 3) in the Y-axis direction is 7.5 mm, and the dimension β5 in the Z-axis direction is 10 mm.

[0032] The second opposing surface 232 has a rectangular shape that is elongated in the X-axis direction, and the dimension β6 in the Z-axis direction is the same as the second interval α2. In this embodiment, the dimension β1 in the X-axis direction of the second opposing surface 232 is 75 mm, and the dimension β6 in the Z-axis direction is 50 mm.

[0033] The indicator portion 3 is a portion that serves as an indicator of the thickness of the sprayed insulation material 6 (see FIG. 5) sprayed from the wall surface 5A. Specifically, the indicator portion 3 is a portion that is recessed inward in the Y-axis direction from the second opposing surface 232 (circumferential surface 23) and extends in the X-axis direction. The indicator portion 3 of this embodiment is composed of a first surface 31 that spreads in a planar direction perpendicular to the Z-axis direction and a second surface 32 that spreads in a planar direction perpendicular to the Y-axis direction. In the spacer member 1 of this embodiment, the distance between the first surface 31 of the indicator portion 3 and the wall mounting surface 21 in the Z-axis direction is the second distance α2. In this embodiment, the dimension β1 of the first surface 31 in the X-axis direction is 75 mm, and the dimension β4 in the Y-axis direction is 7.5 mm. Moreover, the dimension β1 of the second surface in the X-axis direction is 75 mm, and the dimension β5 in the Z-axis direction is 10 mm.

[0034] Next, a method for installing interior material 8 using spacer member 1 configured as above will be described with reference to Figs. 4 to 6F.

[0035] First, an adhesion process (spacer attachment process) is performed in which a plurality of spacer members 1 are adhered to a wall surface 5A of a concrete wall 5. In this adhesion process, the spacer members 1 are adhered to the wall surface 5A by an adhesive such as a modified silicone adhesive. That is, the spacer members 1 are adhered to the wall surface 5A via an adhesive layer 4 formed by the adhesive (see Figs. 6A and 6B).

[0036] In this bonding process, the multiple spacer members 1 are bonded to the wall surface 5A at intervals. Of the multiple spacer members 1 bonded to the wall surface 5A, certain spacer members 1 are bonded to the wall surface 5A so as to be lined up at intervals in a predetermined direction (the horizontal direction in the example shown in FIG. 4). The rows of spacer members 1 spaced apart in the horizontal direction may be formed in multiple rows spaced apart in the vertical direction. Each of the spacer members 1 lined up in the predetermined direction is bonded to the wall surface 5A so that the longitudinal direction (X-axis direction) of the component mounting surface 22 coincides with the predetermined direction (the horizontal direction in the example shown in FIG. 4).

[0037] Next, a spraying process is performed in which the spray insulation material 6 is sprayed onto the wall surface 5A with the plurality of spacer members 1 adhered to the wall surface 5A (see FIG. 6C). The spray insulation material 6 in this embodiment is a rigid urethane foam, which is foamed by mixing two liquid chemicals during spraying and is sprayed onto the wall surface 5A. The thermal conductivity of this spray insulation material 6 is 0.026 W / m·k.

[0038] In this spraying process, the spray insulation 6 is sprayed onto the wall surface 5A using the indicator portion 3 of each spacer member 1 as an indicator. More specifically, in the spraying process, the spray insulation 6 is sprayed onto the wall surface 5A so that the position of the surface 6A of the spray insulation 6 after spraying is the position of the indicator portion 3, more specifically, the position of the first surface 31 of the indicator portion 3 in the Z-axis direction. As a result, the protruding portion formed by the member mounting surface 22 and the pair of second surfaces 32 of each spacer member 1 protrudes from the surface 6A of the spray insulation 6.

[0039] Next, a component mounting process is performed in which the interior material 8 or a fixing member 7 for fixing the interior material 8 is mounted on the component mounting surface 22 of the spacer member 1. This component mounting process includes a base material mounting process in which the fixing member 7 is mounted on the spacer member 1 or the like, and an interior material fixing process in which the interior material 8 is fixed to the fixing member 7.

[0040] In this construction method, the convex portion of the spacer member 1 (the portion formed by the component mounting surface 22 and a pair of second surfaces 32) protrudes from the surface 6A of the sprayed insulation material 6 sprayed onto the wall surface 5A, so that when the interior material 8 is attached to the component mounting surface 22 in the mounting process or when the interior material 8 is attached via the fixing member 7, a specified gap space can be easily and reliably formed between the surface 6A of the sprayed insulation material 6 and the interior material 8.

[0041] The fixing member 7 in this embodiment includes a gasket (adjustment member) 71, a first wooden shaft 72 extending in the direction in which the specified spacer members 1 are lined up (in this embodiment, the horizontal direction), and a second wooden shaft 73 extending in a direction intersecting the first wooden shaft 72 (in this embodiment, the vertical direction). The base material mounting process includes a first mounting process of mounting the gasket 71 to the spacer member 1, a second mounting process of mounting the first wooden shaft 72 to the gasket 71, and a third mounting process of mounting the second wooden shaft 73 to the first wooden shaft 72.

[0042] In the first mounting step, packings 71 are attached to each of the component mounting surfaces 22 of the spacer members 1 arranged in the horizontal direction (see FIG. 6D). Here, the packings 71 are square pieces of lumber measuring 30 mm×30 mm and having a length of approximately 100 mm. The packings 71 are attached to the component mounting surfaces 22 with nails N or screws so that the length direction of the packings 71 coincides with the longitudinal direction (X-axis direction) of the component mounting surfaces 22 of the spacer members 1. The packings 71 in this embodiment are attached with nails N.

[0043] In the second attachment step, the first wooden shaft 72 is attached to each packing 71 so as to overlap vertically with each packing 71 attached to the horizontally aligned spacer members 1 (see FIG. 6E). In the second attachment step of this embodiment, the first wooden shaft 72 is attached to the packing 71 so as to contact the packing 71 from below. At this time, the first wooden shaft 72 is attached (fixed) to each spacer member 1 by nails, screws, adhesive, etc. In the second attachment step of this embodiment, multiple first wooden shafts 72 are arranged at intervals in the vertical direction.

[0044] At this time, a positional deviation of up to about 10 mm occurs between the component mounting surfaces 22 of each spacer component 1 that are aligned horizontally in the normal direction of the wall surface 5A due to manufacturing errors of the wall surface 5A, etc. For this reason, at the mounting positions of the first wooden shaft 72 and each packing 71, the first wooden shaft 72 can be positioned straight by mounting the first wooden shaft 72 to each packing 71 while adjusting the amount of overlap between the first wooden shaft 72 and each packing 71 in the normal direction (amount of overlap in the Z-axis direction: see symbol L in FIG. 5).

[0045] In the third attachment step, the second wooden shafts 73 are attached to the first wooden shaft 72 at intervals in the horizontal direction (the direction in which the first wooden shaft 72 extends). The second wooden shafts 73 in this embodiment are attached (fixed) to the first wooden shaft 72 with nails, screws, or the like.

[0046] Once the attachment (positioning) of the fixing members 7 (gasket 71, first wooden shaft 72, second wooden shaft 73) to the wall surface 5A is completed through the above-mentioned base material attachment processes (first to third attachment processes), the interior material fixing process is then carried out (see Figure 6F).

[0047] In this interior material fixing process, the interior material 8 is attached (fixed) to the first wooden shaft 72 and the second wooden shaft 73. The interior material 8 in this embodiment is a plate-shaped member, for example, an inner wall such as gypsum board or plywood. This interior material 8 is fixed to the first wooden shaft 72 and the second wooden shaft 73 with nails, screws, or the like.

[0048] The construction method using the spacer member 1 described above includes an adhesion process (spacer mounting process) of mounting the spacer member 1 to the wall surface 5A, the spacer member 1 including, on its surface 2, a wall mounting surface 21 that is attached to the wall surface 5A (in this embodiment, it is glued), a component mounting surface 22 that is arranged at a first distance α1 from the wall mounting surface 21 in the Z-axis direction (normal direction to the wall mounting surface 21) and to which an interior material 8 or a fixing member 7 for fixing the interior material 8 is attached, and a peripheral surface 23 between the wall mounting surface 21 and the component mounting surface 22, a spraying process of spraying spray insulation material (spray material) 6 onto the wall surface 5A with the spacer member 1 attached to the wall surface 5A, and a component mounting process of attaching the interior material 8 or the fixing member 7 for fixing the interior material 8 to the component mounting surface 22 of the spacer member 1. The spacer member 1 has an index portion 3 on its peripheral surface 23 which indicates a position spaced a second distance α2 from the wall mounting surface 21 in the Z-axis direction, and the second distance α2 is smaller than the first distance α1. In the spraying process, the spray insulation material 6 is sprayed onto the wall surface 5A using the index portion 3 as an indicator.

[0049] In this way, by spraying the spray insulation 6 onto the wall surface 5A using the indicator portion 3 of the spacer member 1 bonded to the wall surface 5A as an indicator, it becomes easy to control the thickness of the spray insulation 6 during the spraying work. That is, since the second interval α2 is smaller than the first interval α1, by spraying the spray insulation 6 using the indicator portion 3 as an indicator, it is possible to prevent the spray insulation 6 sprayed onto the wall surface 5A from being too thick (overspraying), while by spraying the spray insulation 6 using the indicator portion 3 indicating the desired position (the position spaced the second interval α2 from the wall mounting surface 21) as an indicator, it is possible to prevent the spray insulation 6 sprayed onto the wall surface 5A from being too thin (insufficient spraying) even if the wall surface 5A is not visible due to the sprayed spray insulation 6 (i.e., spray the spray insulation 6 while adjusting the thickness).

[0050] In the spraying process of the application method of this embodiment, the spray insulation material 6 is sprayed onto the wall surface 5A so that the surface 6A of the spray insulation material (spray material) 6 after spraying is positioned at the position of the indicator portion 3. This makes it easy to obtain the spray insulation material 6 of the desired thickness (second interval) α2 from the wall surface 5A.

[0051] Furthermore, in the construction method of this embodiment, in the member mounting step, after the fixing member 7 is mounted, the interior material 8 is mounted to the fixing member 7. By disposing the fixing member 7 between the spacer member 1 and the interior material 8 in this manner, it becomes easier to adjust the distance between the spray insulation material 6 (surface 6A of the spray insulation material 6) and the interior material 8.

[0052] Furthermore, in the construction method of this embodiment, by restricting the foaming ratio of the spacer member 1 to 2.2 to 2.3 times, it is possible to prevent the nails N used when attaching the packing 71 to the member attachment surface 22 of the spacer member 1 from coming out. That is, by setting the foaming ratio of the spacer member 1 of this embodiment to 2.2 to 2.3 times, it is possible to prevent the nails N for driving the packing 71 (fixing member 7) from coming out of the spacer member 1, thereby achieving a balance between the weight reduction of the spacer member 1 and the difficulty of the nails N coming out.

[0053] The spacer member 1 of this embodiment is a spacer member 1 including, on its surface 2, a wall mounting surface 21 that is attached (glued in this embodiment) to the wall surface 5A, a component mounting surface 22 that is arranged at a first distance α1 from the wall mounting surface 21 in the Z-axis direction (the normal direction to the wall mounting surface 21) and to which an interior material 8 or a fixing member 7 for fixing the interior material 8 is attached, and a peripheral surface 23 between the wall mounting surface 21 and the component mounting surface 22, and is provided with an indicator portion 3 that indicates a position at the peripheral surface 23 separated by a second distance α2 from the wall mounting surface 21 in the Z-axis direction and serves as an indicator of the thickness of the spray from the wall surface 5A. The second distance α2 is smaller than the first distance α1.

[0054] According to this configuration, the thickness of the spray insulation 6 can be easily controlled during the spraying operation by spraying the spray insulation 6 onto the wall surface 5A using the indicator portion 3 of the spacer member 1 adhered to the wall surface 5A as an indicator. That is, since the second interval α2 is smaller than the first interval α1, spraying the spray insulation 6 using the indicator portion 3 as an indicator can prevent the spray insulation 6 sprayed onto the wall surface 5A from being too thick (overspraying), while spraying the spray insulation 6 using the indicator portion 3 indicating the desired position (the position spaced the second interval α2 from the wall mounting surface 21) as an indicator can prevent the spray insulation 6 sprayed onto the wall surface 5A from being too thin (insufficient spraying).

[0055] Moreover, in the spacer member 1 of this embodiment, the indicator portion 3 is configured by a recess. In this way, by forming the indicator portion 3 into a three-dimensional configuration such as a recess, it becomes easier for a worker to visually recognize the indicator portion 3 even at a site where spraying work is performed (such as an indoor site where the amount of light is insufficient). Furthermore, the weight of the spacer member 1 can be reduced compared to a rectangular parallelepiped spacer member without a recess.

[0056] The construction method using the spacer member for interior construction and the spacer member for interior construction of the present invention are not limited to the above-mentioned embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, part of the configuration of one embodiment can be deleted.

[0057] There are no limitations on the specific dimensions (β1 to β6) of the parts of the spacer member for interior work 1. Also, the shape of the spacer member for interior work 1 seen from the Z-axis direction is rectangular, but is not limited to this configuration and may be circular, polygonal, etc. In other words, the spacer member for interior work 1 only needs to have two parallel surfaces (wall mounting surface 21, member mounting surface 22) and the indicator portion 3 arranged on the peripheral surface 23.

[0058] In addition, the indicator portion 3 of the interior construction spacer member 1 in the above embodiment has a notch shape recessed in the Y-axis direction from the peripheral surface 23 (specifically, the second opposing surface 232) and extending in the X-axis direction, but is not limited to this configuration. For example, the indicator portion 3 may be configured by a line or a mark printed on the peripheral surface 23. In addition, the indicator portion 3 may be configured by a protrusion or a groove extending in the circumferential direction of the peripheral surface 23 (in the above embodiment, the first opposing surface 231 extends in the X-axis direction and the second opposing surface 232 extends in the Y-axis direction). That is, the indicator portion 3 may be configured by a protrusion or a recess. In this way, by making the indicator portion 3 a three-dimensional configuration such as a protrusion or a recess, it becomes easier for a worker to see the indicator portion even at a site where spraying work is performed (such as an indoor site with insufficient light).

[0059] Moreover, the indicator portion 3 of the spacer member 1 for interior construction may be disposed only on the second opposing surface 232 of the peripheral surface 23, or may be disposed only on the first opposing surface 231.

[0060] In addition, the wall mounting surface 21 of the interior construction spacer member 1 in the above embodiment has multiple recesses 21a, but is not limited to this configuration. The wall mounting surface 21 may have multiple protrusions, or multiple recesses and multiple protrusions. With these configurations, the surface area is increased compared to a flat surface, and the adhesive strength with the adhesive layer 4 when adhering to the wall surface 5A via the adhesive layer 4 is improved.

[0061] In the construction method of the above embodiment, the wall surface 5A to which the interior construction spacer member 1 is adhered is a wall surface extending in a plane direction perpendicular to the horizontal direction, but this is not limited to the configuration. The direction in which the wall surface 5A to which the interior construction spacer member 1 is adhered faces is not limited.

[0062] In the construction method of the above embodiment, the fixing member 7 is attached to the member mounting surface 22 of the spacer member 1 for interior work, and the interior material 8 is attached (fixed) to the fixing member 7, but the present invention is not limited to this configuration. The interior material 8 may be attached directly to the member mounting surface 22 of the spacer member 1 for interior work.
