Description

Technical Field

[0001] The present invention relates to a building, and more particularly to a building in which water utilization facilities are used indoors.

Background Art

[0002] When changing the layout of indoor spaces by renovation or the like in buildings such as houses, there are cases where spaces where water utilization facilities are arranged, that is, so-called plumbing spaces, such as bathrooms, kitchens, washrooms, and toilets, are relocated. Generally, the walls and floors of plumbing spaces have different specifications and structures from those of rooms other than plumbing spaces. Therefore, when relocating a plumbing space in a conventional house, it has generally been necessary to demolish the entire floor including the floor of the plumbing space and the walls surrounding the plumbing space for a full-scale renovation.

[0003] On the other hand, considering the above points, buildings that can easily relocate plumbing spaces have been proposed. As an example, there is the house described in Patent Document 1. In the house described in Patent Document 1, a concave groove band is provided in a part of the floor surface, and a plurality of unit equipment rooms including kitchens, bathrooms, and toilets can be relocated within a certain area including this concave groove band. Thereby, it is possible to relatively easily change the layout including the plumbing space.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the house described in Patent Document 1, since the moving range of the unit equipment room is limited to the range where the above-described recessed band is provided, the degree of freedom in relocating the plumbing space is restricted. Further, when moving the unit equipment room, since the walls, floor, ceiling, and indoor equipment of the unit equipment room are integrally moved, the work load becomes large.

[0006] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a building in which the installation space of water-using equipment can be more easily relocated and the degree of freedom in relocation is improved.

Means for Solving the Problems

[0007] According to the building of the present invention, the above problems are solved by a plurality of floor panels arranged to form the floor of the indoor space and having changeable arrangement positions on the floor, a water-using facility installed on a first panel among the plurality of floor panels and using water supplied to the indoor space, a second panel adjacent to the first panel on the floor, and a wall panel erected between the first panel and the second panel and removable. When the arrangement position of the first panel is changed, the wall panel is removed along with the movement of the first panel and erected between the second panel adjacent to the first panel at the changed arrangement position and the first panel. In the building of the present invention configured as described above, by changing the arrangement position of the first panel on which the water-using facility is placed and moving the wall panel accordingly, the installation space (plumbing space) of the water-using facility can be relocated relatively easily. Further, since the arrangement position of the first panel on the floor can be freely changed, the degree of freedom in relocation is improved.

[0008] Further, in the building of the present invention, a support member for supporting the wall panel between the second panel and the first panel may be provided, and the support member may have a holding portion for holding the lower end portion of the wall panel in a state of being disposed in the gap between the second panel and the first panel. According to the above configuration, when the arrangement position of the first panel is changed, the wall panel that moves accordingly can be appropriately arranged at the moved position by the support member.

[0009] Further, in the above configuration, it is preferable that the holding portion has a concave portion, and the fitting member housed in the concave portion fits with the lower end portion of the wall panel to hold the lower end portion of the wall panel. With such a configuration, the wall panel can be more appropriately arranged at the moved position.

[0010] Further, in the above configuration, it is more preferable that the support member includes a flat mounting portion on which the first panel is mounted, and a connecting portion that connects the mounting portion and the holding portion. According to such a configuration, both the first panel whose arrangement position has been changed and the wall panel that has moved along with the change in the arrangement position of the first panel can be appropriately arranged by the support member.

[0011] Further, the building of the present invention may include a positioning member for positioning the second panel, and a fixing member that engages with the support member and to which the support member is fixed. In this case, it is preferable that a part of the fixing member is arranged along a part of the positioning member at a position adjacent to the positioning member. With the above configuration, the wall panel can be arranged at an appropriate orientation and arrangement position with respect to the second panel by the positioning member, the support member, and the fixing member.

[0012] Further, in the above configuration, it is even more preferable that the lower end portion of the fixing member is bent toward the side where the first panel is arranged and engages with the holding portion of the support member in the vertical direction. With the above configuration, a water-stopping function can be added to the fixing member. Further, the lower end portion of the fixing member engages with the holding portion of the support member, so that the joint property between the fixing member and the support member can be improved.

[0013] Further, in the above configuration, a panel receiving member that receives the floor panel from below and supports the floor panel may be provided, and the support member and the fixing member may be installed on the panel receiving member. According to the above configuration, the support member and the fixing member can be appropriately arranged by using the panel receiving member.

[0014] Further, in the building of the present invention, the first panel may be installed on the floor in a state where the upper surface of the first panel is inclined with respect to the horizontal plane. According to the above configuration, a gradient for draining water can be provided in the floor area of the installation space for water utilization facilities, and the installation space for water utilization facilities can be appropriately utilized.

[0015] Further, in the building of the present invention, when the arrangement position of the first panel is changed, among the plurality of floor panels, on the floor before the arrangement position of the first panel is changed, the floor panel at the arrangement position of the first panel after the change and the first panel may be exchanged. According to the above configuration, the installation space for water utilization facilities can be reasonably (economically) relocated without requiring the disposal and modification of the floor panel.

Effects of the Invention

[0016] According to the present invention, it is possible to more easily relocate the installation space for water utilization equipment, and a building with improved freedom of relocation can be realized.

Embodiments for Carrying Out the Invention

[0018] <<Regarding a building according to one embodiment of the present invention>> Hereinafter, a building according to one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the accompanying drawings. In the drawings, for the sake of easy understanding of the explanation, each member is illustrated in a somewhat simplified and schematic manner. Also, the sizes (dimensions) of each member shown in the drawings and the intervals between members, etc. are different from the actual ones. Also, among the equipment and devices in the building, those not related to the present invention and those with low relevance to the present invention will be omitted from the illustration.

[0019] Also, in the following description, when explaining the position, state (posture), and orientation of each equipment and each component, the content when the equipment and component are being used in the building will be described.

[0020] The building of the present invention is a building having the features (characteristic structures, properties, and functions) of the present invention to be described hereinafter. Hereinafter, a detached house will be taken as an example of the building for explanation. However, the building of the present invention is not limited to a detached house, and may be an apartment house, or a building other than a house, specifically, an office, a store, a shed, a warehouse, an office building, a commercial facility, a public facility, etc. Also, the detached house may be a single-story (bungalow) or a multi-story building.

[0021] The house according to this embodiment (hereinafter referred to as house 10) has an indoor space 12 surrounded by a ceiling, a floor, and side walls. The indoor space 12 here may be a space on the first floor, or may be a space on the second floor or above when the house 10 has multiple floors. As shown in FIG. 1, the indoor space 12 is partitioned into a plurality of spaces by partition walls or partitions (indicated by broken lines in FIG. 1). In other words, within the house 10, spaces for each use are arranged in a determined floor plan. Among the plurality of spaces, there is included a space where water-using facilities that utilize water (specifically, city water or well water) supplied to the indoor space 12 are arranged, that is, a plumbing space 14.

[0022] The water-using facilities are facilities that use water within the indoor space 12, specifically, kitchen facilities, bathtubs, showers, washbasins, toilets, and other sanitary facilities, etc. The plumbing space 14 is a space where one or more such water-using facilities are installed, specifically, kitchens, bathrooms, washrooms, and toilets, etc. Also, water supply lines and drainage lines made of pipes or hoses, etc. are laid around the plumbing space 14 and its periphery, and the water supply ports at the ends of the water supply lines are connected to the water-using facilities, or are arranged facing the water receiving parts provided on the water-using facilities. Hereinafter, the description will focus on the bathroom, which is one of the plumbing spaces 14. Note that the following description can also be applied to plumbing spaces other than the bathroom included in the indoor space 12.

[0023] The bathroom as the plumbing space 14 has a configuration in which the continuity with the spaces and rooms around the bathroom is blocked within the indoor space 12 from the perspective of moisture prevention, and is partitioned by a ceiling, a floor, and walls. The ceiling, floor, and walls of the bathroom are made of materials having water repellency, water resistance, or waterproofness, and have different specifications and structures from the ceiling, floor, and walls of spaces different from the plumbing space 14 such as the bathroom. Also, the floor surface of the bathroom is inclined so that water flows toward a drain groove (not shown), in other words, a gradient for draining water is provided on the floor surface of the bathroom (see FIG. 3).

[0024] Incidentally, in the present embodiment, as shown in FIG. 2, the floor 20 of the indoor space 12 is configured by arranging a plurality of floor panels 22. The floor panel 22 is a panel having a rectangular or square shape in plan view and is made of a known panel-shaped building material for floors. Further, the size, material, and shape of the floor panel 22 are not particularly limited as long as they are set according to the application or the like. Note that the floor panels 22 other than the first panel 24 described later may be general-purpose products used to form the floor of the general part (space other than the plumbing space 14) of the indoor space 12.

[0025] The plurality of floor panels 22 that make up the floor 20 are arranged in a grid pattern (grid-like), that is, a plurality are arranged in each of the column direction and the direction between beams of the house 10. Note that the number of floors 20 that make up the floor 20 is not particularly limited.

[0026] Also, in the floor 20 according to the present embodiment, each floor panel 22 is detachably arranged by the mounting hardware 30 described later. In other words, in the present embodiment, the arrangement position of each floor panel 22 on the floor 20 can be changed. For example, among the plurality of floor panels 22 that make up the floor 20, two different floor panels 22 can be exchanged and their respective arrangement positions can be changed.

[0027] The plurality of floor panels 22 include a first panel 24 that constitutes a floor area (hereinafter referred to as the bathroom floor area) arranged in the bathroom (plumbing space 14) of the indoor space 12. That is, as shown in FIG. 3, a bathtub 60 is arranged on the first panel 24 that constitutes the floor of the bathroom, and strictly speaking, it is placed on the first panel 24. Note that the number of the floor panels 22 that correspond to the first panel 24 (that is, the floor panels 22 used for the purpose of constituting the bathroom floor area) among the plurality of floor panels 22 is not particularly limited and may be one or a plurality.

[0028] The first panel 24 is different from the other floor panels 22 and is designed and structured for use in a bathroom. Specifically, it is made of a highly waterproof material such as tiles. Also, for reasons such as ensuring water drainage, the first panel 24 is installed on the floor 20 (strictly speaking, the floor area of the bathroom) with its upper surface inclined with respect to the horizontal plane (see Fig. 5). Further, joints may be installed on the first panel 24 as connection ports for the water supply line and the drainage line laid in the plumbing space 14. Known joints such as coupling joints can be used as the joints. Also, the method of attaching the joints to the first panel 24 is not particularly limited.

[0029] Also, in the present embodiment, as described above, since each of the plurality of floor panels 22 including the first panel 24 is movable, the arrangement position of the first panel 24 on the floor 20 can be changed. Specifically, as shown in Fig. 2, among the plurality of floor panels 22, the floor panel 22 (hereinafter referred to as the replacement target panel 23) located at the arrangement position of the first panel 24 after the change on the floor 20 before the arrangement position of the first panel 24 is changed, and the first panel 24 can be exchanged. Thereby, the arrangement position of the first panel is changed, and as a result, the position of the bathroom floor area on the floor 20 can be changed. That is, in the house 10 of the present embodiment, the bathroom (plumbing space 14) can be relocated in the indoor space 12. In Fig. 2, the hatched floor panel 22 corresponds to the first panel 24, and the floor panel 22 painted in gray corresponds to the replacement target panel 23.

[0030] Also, among the plurality of floor panels 22, the floor panel 22 adjacent to the bathroom floor area (in other words, adjacent to the first panel 24) will be hereinafter referred to as the second panel 26. The second panel 26 constitutes the floor of the space (general area) other than the plumbing space 14 in the indoor space 12 and is a floor panel 22 with general specifications and structure.

[0031] And between the first panel 24 and the second panel 26, a wall panel 28 that partitions the bathroom from its surrounding space is erected. Specifically, as shown in FIGS. 3 to 5, a gap is provided between the first panel 24 and the second panel 26, mounting hardware 30 is disposed within this gap, and the lower end portion of the wall panel 28 is inserted into the above-described gap and held by the mounting hardware 30. Thereby, the wall panel 28 is installed between the first panel 24 and the second panel 26 and stands up at its installation position.

[0032] The wall panel 28 has a configuration necessary as a wall material for the bathroom, but in other respects, it has the same specifications and structure as a general wall panel. Also, in the present embodiment, the wall panel 28 is installed in a removable state. Specifically, when the arrangement position of the first panel 24 is changed, the wall panel 28 is removed as the first panel 24 moves, and is erected between the second panel 26 adjacent to the first panel 24 at the changed arrangement position and the first panel 24.

[0033] For changing the arrangement position of the first panel 24 and relocating the wall panel 28, the mounting hardware 30 shown in FIG. 5 is used. The mounting hardware 30 is composed of three pieces of hardware, namely a support member 31, a fixing member 36, and a positioning member 40, and is disposed on the joist 50 as shown in FIG. 5. The joist 50 corresponds to a panel receiving member, is disposed across two adjacent floor panels 22, receives each of these floor panels 22 from below, supports the floor panel 22, and is formed of, for example, steel (H-shaped steel or I-shaped steel).

[0034] The support member 31 is a component that supports the wall panel 28 between the second panel 26 and the first panel 24. As shown in FIG. 5, the support member 31 has a holding portion 32 that holds the lower end portion of the wall panel 28, a placement portion 33 on which the first panel 24 is placed, and a connecting portion 34 that connects the placement portion 33 and the holding portion 32. In the present embodiment, each part of the support member 31 is formed by bending a single metal plate.

[0035] The holding portion 32 holds the lower end portion of the wall panel 28 while being disposed within the gap between the second panel 26 and the first panel 24. More specifically, as shown in FIG. 5, the holding portion 32 has a shape bent in a substantially J shape in side view, and has a groove-shaped recess 32a in its lower portion. A receiving member 35 as a fitting member is accommodated within the recess 32a. The receiving member 35 is a gasket such as a glazing channel, and is made of a material such as rubber or resin, for example. Then, the holding portion 32 holds the lower end portion of the wall panel 28 by the receiving member 35 within the recess 32a fitting with the lower end portion of the wall panel 28.

[0036] The placing portion 33 is a flat plate-like portion, and as shown in FIG. 5, extends in a direction inclined with respect to the horizontal direction. Thereby, when the first panel 24 is placed on the placing portion 33, the upper surface of the first panel 24 is in a somewhat inclined state. The inclination direction at this time is set such that the upper surface of the first panel 24 gradually descends as it approaches the position of the drain outlet (drain groove) in the bathroom. Note that the means for fixing the first panel 24 placed on the placing portion 33 is not particularly limited, but the first panel 24 may be fixed to the placing portion 33 with screws or the like, or the first panel 24 may be fixed with an adhesive or tape provided on the upper surface of the placing portion 33.

[0037] The connecting portion 34 is provided between the end portion of the holding portion 32 on the placing portion 33 side and the end portion of the placing portion 33 on the holding portion 32 side, and connects both of them.

[0038] As shown in FIG. 5, the positioning member 40 has a bent portion 41 bent in a substantially L shape in side view, and a hanging portion 42 hanging down from the tip of the horizontal portion of the bent portion 41. In the present embodiment, each portion of the positioning member 40 is formed by bending a single metal plate.

[0039] The bent portion 41 is fixed to the joist 50 by screws or the like while being placed (mounted) on the upper surface of the joist 50. Further, the bent portion 41 has a vertical portion extending in the vertical direction (up and down direction) and a horizontal portion extending in the horizontal direction. As shown in FIG. 5, the lower corner portion of the second panel 26 is brought into contact with both of these to position the second panel 26. The hanging portion 42 is locked to the side end of the flange portion of the H-shaped steel constituting the joist 50 as shown in FIG. 5. Thereby, the positioning member 40 is positioned with respect to the joist 50. Note that the hanging portion 42 is not limited to the configuration shown in FIG. 5, and may be bent in an L shape and function as a clip that sandwiches the flange portion of the joist 50 together with the horizontal portion of the bent portion 41.

[0040] The fixing member 36 is a component that engages with the support member 31 and to which the support member 31 is fixed, and is formed by bending a single metal plate. The fixing member 36 is arranged at a position adjacent to the positioning member 40 on the side opposite to the second panel 26 as shown in FIG. 5. More specifically, the fixing member 36 is arranged using the space between the first panel 24 and the second panel 26 and is placed (mounted) on the upper surface of the joist 50.

[0041] As shown in FIG. 5, the fixing member 36 has a shape bent in a substantially J shape in side view. In other words, the lower end portion of the fixing member 36 is bent toward the side where the first panel 24 is arranged to form a bent portion 37. Then, as shown in FIG. 5, the holding portion 32 of the support member 31 enters into the bent portion 37, so that the bent portion 37 engages with the holding portion 32 in the vertical direction (up and down direction). In this embodiment, the lower end portion of the fixing member 36 is bent toward the first panel 24 side, that is, toward the inside of the bathroom, so that the fixing member 36 also functions as a water stop member that prevents water from entering from the bathroom into the general area.

[0042] Further, as shown in FIG. 5, the fixing member 36 has a rising portion 38 extending along the vertical direction (up and down direction) as a part of the fixing member 36. The rising portion 38 is disposed at a position adjacent to the vertical portion (corresponding to a part of the positioning member 40) of the bent portion 41 of the positioning member 40 along the vertical portion. Further, in a state where the fixing member 36 is engaged with the holding portion 32 of the support member 31, the rising portion 38 is along the portion of the support member 31 extending in the vertical direction. And the rising portion 38 is joined (for example, screwed) to the bent portion 41 of the positioning member 40 together with the portion of the support member 31 extending in the vertical direction. Thereby, the support member 31 is fixed to the fixing member 36.

[0043] Further, as shown in FIG. 5, the upper end portion of the rising portion 38 is bent toward the positioning member 40 side to form a locking portion 39. The locking portion 39 is locked to the upper end of the vertical portion of the bent portion 41 of the positioning member 40 in the vertical direction. By locking the locking portion 39 to the upper end of the positioning member 40 in this way, the arrangement position of the fixing member 36 with respect to the positioning member 40 is determined. And in a state where the arrangement position of the fixing member 36 is determined, the fixing member 36 is joined to the bent portion 41 of the positioning member 40 together with the support member 31 in the above-described manner.

[0044] A plurality of wall panels 28 are arranged so as to surround the bathroom, and the above-mentioned fitting hardware 30 is used for each wall panel 28. Further, an overhead panel 44 forming the ceiling of the bathroom is installed above the plurality of wall panels 28. The overhead panel 44 is also installed in a detachable state, similar to the first panel 24 and the wall panel 28, and is removed when the bathroom is relocated and reinstalled according to the arrangement position of the bathroom after relocation.

[0045] [Procedure for relocating the plumbing space] Next, a procedure for relocating the plumbing space 14, specifically the bathroom, for the purpose of changing the floor plan in the indoor space 12 of the house 10 will be described with reference to FIGS. 2 and 6.

[0046] When relocating the bathroom, first, the bathtub 60, which is a water-using facility, is removed. Also, at this stage, each of the water supply line and the drainage line connected to the bathroom is shut off. For example, the joints provided in each line are removed, and the connection between the portion located upstream of the joint and the portion located downstream of the joint is released.

[0047] Next, as shown in Fig. 2, the first panel 24 is removed, and the wall panel 28 and the ceiling panel 44 surrounding the bathroom are removed. At this time, the support member 31 on which the first panel 24 is placed (in other words, the support member 31 that supported the removed wall panel 28) is removed from the fixing member 36 by releasing the engagement state between its holding portion 32 and the bent portion 37 of the fixing member 36. As a result, on the floor 20, the first panel 24 is removed together with the support member 31. Then, the fixing member 36 that was engaged with the removed support member 31 is also removed.

[0048] On the other hand, the second panel 26 arranged at a position adjacent to the removed first panel 24 and the positioning member 40 for positioning the second panel 26 are not removed and continue to be arranged (left) at the same position.

[0049] Also, as shown in Fig. 2, among the plurality of floor panels 22 constituting the floor 20, the replacement target panel 23 is removed. Note that the positioning member 40 is installed in the same mounting manner as the second panel 26 for the floor panel 22 adjacent to the replacement target panel 23 (hereinafter referred to as the replacement target adjacent panel).

[0050] After that, the removed first panel 24 and the replacement target panel 23 are swapped. That is, the replacement target panel 23 is arranged at the location where the first panel 24 was arranged until then. Also, the first panel 24 is arranged at the location where the replacement target panel 23 was arranged until then.

[0051] Specifically, as shown in FIG. 6, first, the adjacent panel to be replaced is set as the second panel 26, and the previously removed fixing member 36 is installed at a position adjacent to the positioning member 40 for positioning the second panel 26. Next, the previously removed support member 31 is lowered from above the fixing member 36, and the holding portion 32 provided at the lower end of the support member 31 is inserted into and engaged with the bent portion 37 of the fixing member 36. As a result, the fixing member 36 and the support member 31 are adjacent to each other, and in this state, the fixing member 36 and the support member 31 are fixed to the bent portion 41 of the positioning member 40 with screws or the like. Then, as shown in FIG. 6, the removed first panel 24 is lowered toward the placing portion 33 of the support member 31, placed on the placing portion 33, and fixed.

[0052] Before lowering the first panel 24 onto the placing portion 33, it is preferable to connect the water supply line and the drain line to the joints attached to the first panel 24 respectively, but they may also be connected after placing the first panel 24 on the placing portion 33.

[0053] By the above procedure, the arrangement position of the first panel 24 is changed. Also, a gap is formed between the first panel 24 at the changed arrangement position and the second panel 26 (the original adjacent panel to be replaced) adjacent to the first panel 24. The wall panel 28 is installed using this gap. More specifically, the holding portion 32 of the support member 31 is arranged in the above gap. As shown in FIG. 6, the wall panel 28 is lowered from above the holding portion 32, and the lower end portion of the wall panel 28 is inserted into the recess 32a provided in the holding portion 32. As a result, the lower end portion of the wall panel 28 is fitted into the receiving member 35 housed in the recess 32a, and as a result, the wall panel 28 is erected between the first panel 24 and the second panel 26.

[0054] After all the plurality of wall panels 28 surrounding the relocated bathroom are installed, the ceiling panel 44 is arranged. When the series of operations up to this point is completed, the relocation of the bathroom is completed.

[0055] According to the present embodiment described above, the plumbing space 14 such as in a bathroom can be relocated relatively easily. Also, the arrangement position of the first panel 24 on the floor 20 can be changed relatively freely. In other words, the degree of freedom in relocating the plumbing space 14 is increased. As a result, for example, when changing the floor plan within the house 10 due to changes such as the life stage of the residents of the house 10, it is possible to freely relocate the plumbing space 14.

[0056] Further, in the present embodiment, when moving the first panel 24 that constitutes the floor of the plumbing space 14, by exchanging the replacement target panel 23 arranged at the moving destination with the first panel 24, the generation of waste materials associated with the relocation of the plumbing space 14 can be suppressed. As a result, damage to the floor 20 can be minimized.

[0057] Furthermore, in the present embodiment, when installing the first panel 24 at the arranged position after movement, the fixing member 36 is attached to the positioning member 40 that positions the second panel 26 (specifically, the second panel 26 adjacent to the first panel 24 at the changed arranged position). Thereafter, the support member 31 is dropped onto the fixing member 36 to engage the two members, and the first panel 24 is placed on the placement portion 33 of the support member 31. Thereby, the first panel 24 can be installed at an appropriate position and orientation with respect to the second panel 26. Specifically, the first panel 24 can be arranged such that the opposing surface (narrow side surface) of the first panel 24 with respect to the second panel 26 and the opposing surface (narrow side surface) of the second panel 26 with respect to the first panel 24 are parallel to each other.

[0058] Also, by using the above-mentioned fittings 30 (support member 31, receiving member 35, and positioning member 40), the first panel 24 can be arranged at an appropriate position (height) in the vertical direction. Specifically, the first panel 24 can be arranged so that no step is formed between the first panel 24 and the second panel 26.

[0059] Furthermore, by using the above-mentioned mounting hardware 30, it is possible to easily attach and detach the wall panel 28 as the arrangement position of the first panel 24 is changed, and to arrange the wall panel 28 at an appropriate position according to the changed arrangement position of the first panel 24.

[0060] <<Regarding Other Embodiments>> So far, one specific embodiment of the building of the present invention has been described with examples. However, the above embodiment is merely an example for facilitating the understanding of the present invention and does not limit the present invention. That is, the present invention can be changed and improved without departing from its gist. In addition, it goes without saying that equivalents of the present invention are included.

[0061] Regarding other embodiments of the present invention, as means for supporting the wall panel 28 between the first panel 24 and the second panel 26, devices other than the above-mentioned mounting hardware 30, for example, known wall panel receiving members (specifically, members corresponding to the receiving material 35) may be used.

[0062] In the above embodiment, when relocating the plumbing space 14, the first panel 24 and the wall panel 28 are relocated separately.
