Description

[Technical field]

[0001] The present invention relates to a wall panel support structure and a wall panel upright support method for supporting a plurality of wall panels in an upright position on guide rails along a floor surface in construction in which a plurality of wall panels are connected to construct an interior wall. [Background technology]

[0002] At construction sites where interior walls of bathrooms and living rooms are constructed, a large number of wall panels mass-produced in a factory are supported in an upright position on guide rails that run along the floor surface FL, and adjacent wall panels aligned along the guide rails are connected to construct the interior walls. When constructing these interior walls, if the guide rails are not positioned horizontally along the floor surface FL due to unevenness in the floor surface FL, the multiple wall panels supported by the guide rails will also be supported at an angle, and the positions of the top ends of each wall panel will differ, resulting in gaps between the ceiling surface and the upright support fittings fixed to the building frame cannot be connected to the tops of the wall panels, making it impossible to support the wall panels upright along a vertical plane.

[0003] Therefore, a support structure for a wall panel is known in which a height adjustment fitting is placed between the wall panel and the guide rail to adjust the height of the guide rail above the floor surface, and the wall panel is supported in an upright position on a guide rail arranged horizontally along the floor surface FL (Patent Document 1).

[0004] The wall panel support structure 100 described in Patent Document 1 will be described below with reference to Figures 9 and 10. In the figures, reference numeral 101 denotes a wall panel that is supported upright on guide rails 102 by the wall panel support structure 100, and a fitting frame 103 having a downward U-shaped cross section is fixed along the lower end of the wall panel 101. A nut 107 is fixed by welding to the flat surface of the fitting frame 103, and a panel adjustment bolt 106, whose male thread portion passes through the fitting frame 103 and screws into the nut 107, is screwed to the fitting frame 103 with its head at the lower end.

[0005] In addition, the guide rail 102 is composed of a gutter-shaped runner member 102A fixed to the floor surface FL with anchor bolts 104, a rail 102B that fits into the inside of the runner member 102A from above, and a horizontal adjustment fitting 102C with a downward U-shaped cross section that is arranged on the rail 102B via a height adjustment fitting 105 and fits around the runner member 102A.

[0006] The height adjustment fitting 105 is composed of a height adjustment bolt whose head abuts the inner top surface of the horizontal adjustment fitting 102C and whose male screw is screwed into the rail 102B, and the height adjustment bolts 105 of the same structure are screwed into a plurality of positions of the rail 102B along the longitudinal direction of the guide rail 102. The height adjustment fitting 105 adjusts the plane of the horizontal adjustment fitting 102C to a horizontal plane even if the floor surface FL is uneven. That is, before the horizontal adjustment fitting 102C is fitted from above onto the runner member 102A, each height adjustment bolt 105 is rotated so that the heads of the plurality of height adjustment bolts 105 screwed into the rail 102B belong to the same horizontal plane, and the horizontal adjustment fitting 102C is placed on the height adjustment bolts 105 whose heads are aligned on the same horizontal plane, and the plane of the horizontal adjustment fitting 102C is adjusted to be horizontal regardless of the unevenness of the floor surface FL.

[0007] The wall panel 101 is supported in an upright position on the guide rail 102 by fitting the fitting frame 103 fixed along its lower edge, fitting onto the level adjustment metal fitting 102C, and placing the panel panel 101 on the level adjustment metal fitting 102C via the panel adjustment bolts 106. Therefore, if the lengths of the panel adjustment bolts 106 protruding downward from the fitting frame 103 are the same, the wall panels 101 placed on the level adjustment metal fitting 102C adjusted along the horizontal plane can be supported at the same height along the horizontal plane. The height of each wall panel 101 can be adjusted by adjusting the amount that each panel adjustment bolt 106 is screwed into the nut 107.

[0008] In addition to this conventional wall panel support structure 100, a height adjustment fitting for adjusting the guide rail so that it is positioned along a horizontal plane can also be provided. The height adjustment fitting is made up of a first angle plate consisting of a first vertical plate having a long hole with the vertical direction as its longitudinal direction and a first horizontal plate supporting the guide rail, a second angle plate consisting of a second vertical plate having a long hole with the vertical direction as its longitudinal direction and a second horizontal plate positioned along the floor surface FL, tightening bolts inserted into the long holes of the first and second vertical plates, and tightening nuts holding the first and second vertical plates stacked along the vertical plane between the tightening bolts. By changing the positions of the long holes of the first and second vertical plates through which the tightening bolts are inserted, the spacing between the first and second horizontal plates can be adjusted, and the height of the guide rail supported by the first horizontal plate above the floor surface FL can be adjusted. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Utility Model Application Publication No. 4-63706 Summary of the Invention [Problem to be solved by the invention]

[0010] However, the adjustment work for supporting and adjusting the guide rail 102 (horizontal adjustment fitting 102C) on the floor surface FL along a horizontal plane using this wall panel support structure 100 is performed by aligning the heads of multiple height adjustment bolts 105 along the same horizontal plane and then placing the horizontal adjustment fitting 102C on the heads of the height adjustment bolts 105, making the adjustment work complicated. If the horizontal adjustment fitting 102C itself is deformed, the plane of the horizontal adjustment fitting 102C will not be horizontal.

[0011] If an opening for rotating and adjusting the height adjustment bolts 105 is formed on the side of the horizontal adjustment fitting 102C, it becomes possible to adjust the horizontal adjustment fitting 102C horizontally while the horizontal adjustment fitting 102C is placed on the heads of multiple height adjustment bolts 105; however, the heads of the height adjustment bolts 105, which are adjusted by moving them back and forth in the vertical direction, must be rotated and adjusted from the side through the opening, making the adjustment work still complicated.

[0012] On the other hand, if a height-adjustable fitting consisting of a pair of angle plates is used, the head of the tightening bolt, which is adjusted by moving it back and forth laterally (in a direction parallel to the floor surface), protrudes to the side of the pair of angle plates consisting of a first vertical plate and a second vertical plate stacked along a vertical plane, making it easy to rotate and adjust the tightening bolt.However, since the guide rail is supported only by the frictional force between the first and second vertical plates held between the tightening bolt and the tightening nut, if the guide rail supports a heavy wall panel, such as a wall panel with ceramic tile panels attached, the insertion position of the tightening bolt's long hole gradually drops, and there is a risk that the guide rail will tilt relative to the horizontal plane.

[0013] In addition, both the height adjustment fittings (height adjustment bolts) 105 of the wall panel support structure 100 and the height adjustment fittings using a set of angle plates are positioned below the guide rails that support the wall panel, which would mar the appearance of the room if left as is. Therefore, in the wall panel support structure 100, the base plate 101a of the wall panel 101 is suspended vertically up to nearly the bottom of the guide rails 102, and the height adjustment fittings 105 are covered by the base plate 101a.

[0014] The present invention has been made in consideration of the above-mentioned conventional problems, and aims to provide a wall panel support structure and a method for supporting a wall panel upright, in which the guide rails supporting the wall panels can be easily adjusted with height-adjustable fittings so that they are positioned along a horizontal plane, and in which the height of the guide rails adjusted with the height-adjustable fittings does not change even when a heavy wall panel is supported by the guide rails.

[0015] Another object of the present invention is to provide a wall panel support structure and a method for supporting a wall panel in an upright position, in which a plurality of height-adjustable metal fittings, the guide rails of which are adjusted so as to be positioned along a horizontal plane, are not visible from inside a room in which the wall panels are installed. [Means for solving the problem]

[0016] In order to achieve the above-mentioned object, the wall panel support structure described in claim 1 comprises a plurality of wall panels, a guide rail that supports the plurality of wall panels and aligns the plurality of wall panels along the guide portion with a guide portion that engages with the bottom surface of each wall panel, an upright support bracket that is connected to the main body and supports the wall panels supported by the guide rail in an upright position along a vertical plane, a plurality of height adjustment brackets that are arranged between the floor surface and the guide rail and can adjust the height of the guide rail above the floor surface, and a floor surface finishing layer that is laid on the floor surface, and is characterized in that the plurality of height adjustment brackets that adjust the height of the guide rail above the floor surface are embedded in the floor surface finishing layer so that the guide rail is positioned along a horizontal plane.

[0017] Even if the floor surface is uneven, the guide rail can be positioned along a horizontal plane by adjusting the height of the guide rail with multiple height-adjusting metal fittings. The multiple height-adjusting metal fittings adjust the height of the guide rail above the floor surface so that the guide rail is positioned along a horizontal plane, and the movable parts that adjust the height are fixed by being embedded in the floor finishing layer. In addition, the height-adjusting metal fittings that are positioned between the floor surface and the guide rail are embedded in the floor finishing layer, and the guide rail is supported at a constant height by the floor finishing layer that is interposed between the floor surface and the guide rail.

[0018] The height adjustment fittings are covered by the floor finishing layer and are not visible from inside the room enclosed by the wall panels.

[0019] The support structure for the wall panel described in claim 2 is characterized in that the height-adjustable metal fitting comprises a first angle plate integrally connected to a first vertical plate having a first insertion hole and a first horizontal plate supporting the guide rail, a second angle plate integrally connected to a second vertical plate having a second insertion hole and a second horizontal plate to be placed on the floor surface, a tightening bolt inserted into the first insertion hole and the second insertion hole, at least one of which is an elongated hole with the vertical direction as its longitudinal direction, and a tightening nut screwed onto the tightening bolt, This is characterized by clamping a first vertical plate and a second vertical plate stacked along a vertical plane between a tightening bolt and a tightening nut.

[0020] The distance between the second horizontal plate placed on the floor surface and the first horizontal plate supporting the guide rail changes depending on the position of the tightening bolt inserted into the long hole. At a height where the first horizontal plate supports the guide rail along a horizontal plane, the tightening bolt is inserted into the first and second insertion holes, at least one of which is a long hole, and the tightening bolt protruding to the side of the height-adjustable fitting is rotated to clamp the first and second vertical plates between the tightening nut and the tightening bolt, thereby adjusting the height of the guide rail so that it is positioned along a horizontal plane.

[0021] The supporting structure for the wall panel according to claim 3 is characterized in that the floor finishing layer is a mortar layer.

[0022] The mortar layer has a certain strength and a small drying shrinkage rate because the cement contains fine aggregate such as silica sand.

[0023] The support structure for a wall panel described in claim 4 is characterized in that the wall panel is formed by laminating a ceramic tile plate integrated with a reinforcing plate on the surface of a rectangular metal frame.

[0024] Even if a heavy ceramic tile board is used for the wall panel, the guide rail does not descend and the panel can be placed along a horizontal surface.

[0025] Since a reinforcing plate is laminated on one ceramic tile plate, the ceramic tile plate is less likely to be damaged.

[0026] The support structure for the wall panel described in claim 5 is characterized in that the upright support fitting is composed of a horizontal plate portion fixed to the main body and having a pin insertion hole drilled therein, and a dowel pin that is inserted vertically into the pin insertion hole and the dowel hole of the wall panel supported by the guide rail.

[0027] The pin insertion holes drilled in the horizontal plate of the upright support bracket fixed to the building structure are positioned horizontally. The dowel holes of the wall panels that can move horizontally are restricted from moving horizontally by inserting the dowel pins vertically into the pin insertion holes, and the wall panels supported by the guide rails are also supported in an upright position on the guide rails.

[0028] The method for supporting a wall panel according to claim 6 comprises: (A) a first step of arranging a plurality of height adjustment fittings between a guide rail supporting a plurality of wall panels and a floor surface, the height of the guide rail above the floor surface being adjustable; (B) a second step of adjusting the height of the guide rail above the floor surface with one or more height adjustment fittings, and arranging the guide rail along a horizontal plane on the floor surface; (C) a third step of engaging a bottom surface of one of the adjacent first wall panels supported along the guide rail with a guide portion of the guide rail and supporting the first wall panel supported by the guide rail in an upright position along a vertical plane with an upright support bracket connected to the framework; (D) a fourth step of engaging a bottom surface of the other second wall panel adjacent to the first wall panel with a guide portion of the guide rail, connecting the second wall panel to the first wall panel along the guide portion, and then supporting the second wall panel supported by the guide rail in an upright position along a vertical plane with an upright support bracket; (E) a fifth step of laying a floor surface finishing layer on the floor surface and embedding a plurality of height adjustment fittings in the floor surface finishing layer; The present invention is characterized in that it comprises:

[0029] In the second step of (B), the guide rail can be positioned horizontally on the floor even if the floor surface is uneven. The height-adjusting fittings that adjusted the height of the guide rail in the second step of (B) are then fixed in place by being embedded in the floor finish layer in the fifth step of (E). Also, in the fifth step of (E), the guide rail is supported at a constant height by the floor finish layer that is interposed between the guide rail and the floor surface.

[0030] The height-adjustable fittings placed between the floor surface and the guide rail in the first step (A) are covered with the floor finishing layer in the fifth step (E) and are not visible from inside the room enclosed by the wall panels.

[0031] The method for supporting a wall panel upright according to claim 7 is characterized in that the floor surface finishing layer laid on the floor surface in the fifth step is a mortar layer.

[0032] The mortar layer used as the floor finishing layer in the fifth step (E) has a prescribed strength and a small drying shrinkage rate because the cement contains fine aggregate such as silica sand. Effect of the Invention

[0033] According to the inventions of claims 1 and 6, even when a guide rail that aligns multiple wall panels along a horizontal plane supports multiple heavy wall panels, the height adjustment fittings that adjust the height of the guide rail are not displaced by the weight of the wall panels and are maintained along the horizontal plane.

[0034] Furthermore, the plurality of height-adjustable fittings that support the guide rail along the horizontal plane are hidden from the inside of the room enclosed by the wall panels, without the need for any special members that serve as concealers.

[0035] According to the invention of claim 2, the tightening bolt can be rotated and adjusted from the horizontal direction to the side of the height-adjustable metal fitting, so that the height of the guide rail can be easily adjusted by the height-adjustable metal fitting.

[0036] In addition, even if the tightening force applied by the tightening bolts and tightening nuts loosens, the guide rail is supported at a constant height by the floor finishing layer interposed between the second horizontal plate placed on the floor surface and the first horizontal plate supporting the guide rail.

[0037] According to the inventions of claims 3 and 7, the mortar layer that finishes the concrete floor surface can be utilized to prevent the guide rail, the height of which is adjusted by the height-adjusting metal fittings, from descending.

[0038] Since the mortar layer has a small drying shrinkage rate, the gap between the guide rail and the floor surface caused by the drying shrinkage of the mortar layer is very small and does not affect the guide rail placed along the horizontal surface even over a long period of time.

[0039] According to the invention of claim 4, even if heavy ceramic tile plates are used for the wall panels, a plurality of wall panels can be aligned on the guide rails arranged along a horizontal plane.

[0040] Since a reinforcing plate is laminated onto one ceramic tile plate, the wall panel is not damaged during transportation from the factory where the wall panels are mass-produced to the construction site where the interior walls are constructed.

[0041] According to the invention of claim 5, by simply dropping the dowel pin into the dowel hole of the wall panel supported by the guide rail, the wall panel supported by the guide rail can be supported in an upright position along a vertical plane. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] A wall panel support structure 1 according to an embodiment of the present invention will be described below with reference to Figs. 1 to 8. The wall panel support structure 1 according to this embodiment is a structure in which a plurality of wall panels 2, 2..., which have been mass-produced in advance at a manufacturing factory, are supported in an upright position along a vertical plane on a guide rail 4 along a horizontal plane on a floor surface FL in construction for connecting a plurality of wall panels 2, 2... inside a building to form an inner wall 10, and the wall panels 2, 2 are aligned along the guide rail 4 in order to connect adjacent wall panels 2, 2. In the following description of each part in this embodiment, the vertical direction in the upright state of the wall panel 2 is the up-down direction, the connecting direction between the wall panels 2, 2 illustrated in Fig. 2 is the left-right direction, the direction in which the ceramic tile plate 24 of the wall panel 2 illustrated in Fig. 3 is attached is the front, and the direction of the frame body 20 is the rear.

[0044] As shown in Figures 1 to 3, the wall panel support structure 1 is composed of a plurality of wall panels 2, 2..., guide rails 4 supporting the plurality of wall panels 2, 2..., upright support brackets 5 connected to the wall surface WA of the main body and supporting the wall panels 2 supported on the guide rails 4 in an upright position along a vertical plane, a plurality of height adjustment brackets 3 arranged between the floor surface FL and the guide rails 4, and a floor finishing layer M laid on the floor surface FL.

[0045] The guide rail 4 supporting the wall panels 2, 2... further comprises an aluminum alloy base runner 41 having a pair of rails 41a, 41a parallel to each other and integrally protruding from the upper surface by die casting along the longitudinal direction, and a thin, strip-like flat bar 42 that is fixed along the lower surface of the base runner 41 with screws to reinforce the base runner 41. The pair of rails 41a, 41a engage with the inner wall surface of the lowermost horizontal rail 22 of the wall panel 2, which will be described later, and act as a guide section that guides the wall panels 2, 2... along the linear guide rail 4, and the wall panels 2, 2... are guided by the pair of rails 41a, 41a and supported on the guide rail 4 aligned on the same plane as each other.

[0046] In order to position the guide rail 4 along a horizontal plane on a concrete floor surface FL, multiple height adjustment fittings 3 are placed between the guide rail 4 and the floor surface FL to adjust the height of the guide rail 4 above the floor surface FL. As shown in Figures 4 to 6, the height adjustment fitting 3 consists of a set of first angle plate 31 and second angle plate 33 formed by bending a rectangular rigid plate at a right angle by press molding, and tightening bolts 35 and tightening nuts 36 that tighten the first vertical plate 31a of the first angle plate 31 and the second vertical plate 33a of the second angle plate 33 which are stacked along the vertical plane.

[0047] The second horizontal plate 33b of the second angle plate 33 is disposed along the floor surface FL, and the second angle plate 33 is fixed to the floor surface FL by anchor bolts 37 that pass through the second horizontal plate 33b and are screwed into the concrete of the floor surface FL. A second long hole 34 with its longitudinal direction extending in the up-down direction is drilled in the center in the left-right direction of the second vertical plate 33a that stands upward at the rear end of the second horizontal plate 33b.

[0048] The first angle plate 31 is formed in the same shape as the second angle plate 33, and the first vertical plate 31a is placed on the front of the second vertical plate 33a of the second angle plate 33 in a position rotated 180 degrees around an axis in the front-rear direction with respect to the second angle plate 33. As a result, the first long hole 32, which is drilled in the center of the left-right direction of the first vertical plate 31a and has a longitudinal direction in the up-down direction, communicates with the second long hole 34 in the front-rear direction, and a tightening bolt 35 can be freely inserted through the first long hole 32 and the second long hole 34. In this rotated position, the first horizontal plate 31b of the first angle plate 31 faces the second horizontal plate 33b above it, and supports the guide rail 4 on its upper surface as shown in FIG. 6.

[0049] The first long hole 32 and the second long hole 34 are longitudinally aligned in the vertical direction, and are partially connected in the front-rear direction, so that the interval between the second horizontal plate 33b and the first horizontal plate 31b, i.e., the height at which the guide rail 4 is supported on the floor surface FL, can be adjusted by inserting the fastening bolt 35. Therefore, at a position where the interval between the second horizontal plate 33b and the first horizontal plate 31b is adjusted so that the guide rail 4 is arranged along a horizontal plane, the fastening bolt 35 is screwed and rotated, and the first vertical plate 31a and the second vertical plate 33a are fastened between the fastening nut 36, thereby fixing the first angle plate 31 to the second angle plate 33 fixed to the floor surface FL. This screwing and rotating operation of the fastening bolt 35 can be performed from the front-rear direction with the guide rail 4 arranged on the multiple height-adjusting fittings 3 along the horizontal plane, so that the height of each height-adjusting fitting 3 can be easily adjusted.

[0050] The multiple height adjustment brackets 3 are arranged at the connecting parts between the wall panels 2, 2 connected on the guide rail 4, and between the guide rail 4 below the midpoint of each wall panel 2 and the floor surface FL, so as to prevent a large bending moment from occurring in the guide rail 4, assuming that the guide rail 4 will receive an evenly distributed load from the heavy wall panel 2.

[0051] The multiple wall panels 2, 2... supported on the guide rails 4 are each formed of the same material and with the same shape. As shown in Figure 1, each wall panel 2 is composed of a frame body 20 with a rectangular outline made of vertical bars 21 and left-right bars 22 assembled in a lattice pattern and fixed with screws, and a single ceramic tile plate 24 with the same outline is affixed to the front of the frame body 20 via a reinforcing plate 23.

[0052] The ceramic tile board 24, which is the decorative board for the wall, is a large area of ​​about 1800 mm long and 850 mm wide, and is formed of a single ceramic tile with a thickness of 6 mm to 10 mm. In conventional ceramic tile construction for interior walls, it is difficult to transport such a large ceramic tile board to the construction site without damaging it, so the ceramic tile is divided into several small pieces and attached to the base such as gypsum board by a wet method using cement or a pressure bonding method using adhesive. Therefore, skilled craftsmen are required to smooth the base surface and to make the surface consisting of many ceramic tiles smooth, and waste such as cement debris, tile debris, and packaging materials for packaging the ceramic tiles is generated at the construction site. In this embodiment, the wall panel 2, whose decorative panel is made of a single large-area ceramic tile plate 24, is manufactured in advance at a manufacturing factory, and a plurality of wall panels 2, 2 are connected to construct the interior wall 10. In particular, the connected wall panels 2 are aligned by a straight guide rail 4, so that the ceramic tile wall surface naturally becomes smooth and no waste material such as that described above is generated at the construction site.

[0053] The reinforcing plate 23 laminated on the back side of the ceramic tile plate 24 is made of a lightweight plate material such as a calcium silicate board, flexible board, or magnesium oxide board, and is formed to the same outer shape as the ceramic tile plate 24. It is fixed to the back surface of the ceramic tile plate 24 with an adhesive or the like to reinforce the large-area ceramic tile plate 24.

[0054] The vertical bars 21 and horizontal bars 22 that make up the frame 20 are each formed from a hard metal material that is resistant to deformation, such as aluminum, galvanized steel, or stainless steel. The vertical bars 21, which are arranged vertically on both the left and right sides of the wall panel 2, are H-shaped steel bars with flanges 21a, 21b perpendicular to the web formed integrally on both the front and rear sides of the web, as shown in Figure 7. The rear flange 21b is formed into a thick rectangular pipe shape so that the vertical bars 21 will not deform even when supporting a ceramic tile board 24 under a heavy load.

[0055] The horizontal crosspiece 22 is formed by dividing the two strip-shaped support pieces 22a, 22b, which are longitudinally aligned in the left-right direction, into three vertical stages, which are connected together by three webs 22c, 22d, and 22e along a horizontal plane. Therefore, the uppermost web 22c and the lowermost web 22e, and the two strip-shaped support pieces 22a and 22b, form the upper and lower ends of the horizontal crosspiece 22 into a gutter shape that opens upward and downward along the left-right direction, respectively. In addition, dowel holes 25a and 25b, through which dowel pins 51, which will be described later, are inserted, are drilled along the vertical direction at two positions in the uppermost web 22c and the middle web 22d of the horizontal crosspiece 22.

[0056] Since the reinforcing plate 23 is fixed to the front surface of the frame body 20 with an adhesive, the front surface of the belt-like support piece 22a at the front of the horizontal crosspiece 22 is exposed on the same plane as the flange 21a at the front of the vertical crosspiece 21. In addition, both left and right ends of the two belt-like support pieces 22a, 22b are drawn inward so as to abut against the inner wall surfaces of the flanges 21a, 21b of the vertical crosspiece 21. As a result, both ends of the horizontal crosspiece 22 abut against the webs of the vertical crosspieces 21, 21 arranged on both the left and right sides of the wall panel 2, so that the horizontal crosspiece 22 is hung between the vertical crosspieces 21, 21 in the left-right direction by screwing a male screw (not shown) that passes through the web of the vertical crosspiece 21 into a female screw portion 22f (see FIG. 3) in which a screw hole is recessed and formed in the middle web 22d of the horizontal crosspiece 22.

[0057] 3, the lowest horizontal crosspiece 22 attached along the lower end of the wall panel 2 is attached between the vertical crosspieces 21, 21 upside down to the other horizontal crosspieces 22, and both ends of the two belt-shaped support pieces 22a, 22b of the lowest horizontal crosspiece 22, which are drawn inward, and both sides of the webs of the vertical crosspieces 21, 21 are cut out from the lower ends at the height of the rail 41a of the guide rail 4. As a result, the pair of rails 41a, 41a of the guide rail 4 engage with the opposing inner surfaces of the two belt-shaped support pieces 22a, 22b of the lowest horizontal crosspiece 21 and the notched grooves cut out from the lower ends of the webs of the vertical crosspieces 21, 21, and guide the wall panel 2 movably along the guide rail 4.

[0058] As shown in FIG. 1, a downward locking plate 26a and an upward locking plate 26b that engage with each other are attached along the rear surface of the flanges 21b at the rear of the left and right vertical bars 21, and adjacent wall panels 2, 2 are aligned in the left-right direction, which is the connecting direction, by rails 41a consisting of two parallel straight protrusions of the guide rail 4, and are connected by engaging the downward locking plate 26a and the upward locking plate 26b via the joint post 6 that is arranged upright between them.

[0059] 7, the joint post 6 is made of a hard metal material that is difficult to deform, such as aluminum, galvanized steel, or stainless steel, and is integrally formed with a post-side web 61 that is a long, plate-like shape with a plane extending in the front-to-rear direction, and a pair of post-side flanges 62, 62 that are long, plate-like shapes with a plane extending in the left-to-right direction and perpendicular to the post-side web 61. The front-to-rear width of the post-side web 61 is approximately equal to the front-to-rear width of the web of the vertical crosspiece 21, and the pair of post-side flanges 62, 62 fit between the flanges 21a, 21b of the vertical crosspieces 21, 21 of adjacent wall panels 2.

[0060] Therefore, the vertical bars 21, 21 of adjacent wall panels 2, 2 and the joint posts 6 placed between them have connecting parts with H-shaped cross sections that overlap each other along the connecting direction, and the wall panels 2, 2 connected together along the same plane via the joint posts 6 can be easily arranged on the straight line rails 4a, and a smooth interior wall 10 can be constructed from the multiple wall panels 2, 2...

[0061] The upright support bracket 5 is used to upright the wall panel 2 supported on the guide rails 4 along the vertical wall surface WA, and as shown in Figure 3, is composed of an L-shaped angle plate 52 fixed to the wall surface WA of the main body with an anchor bolt 54, a horizontal plate portion 53 attached by stacking it on the horizontal plate 52b of the L-shaped angle plate 52, and a dowel pin 51 inserted from above into a pin insertion hole 53a of the horizontal plate portion 53.

[0062] Since the position where the anchor bolt 54 is screwed into the wall surface WA is determined to some extent, in order to adjust the height of the L-shaped angle plate 52 fixed by the anchor bolt 54, a vertical adjustment long hole 5a with the vertical direction as the longitudinal direction is drilled in the vertical plate 52a of the L-shaped angle plate 52, as shown in FIG. 8(a).

[0063] 8(b) and 8(c), the horizontal plate 52b and the horizontal plate portion 53 of the L-shaped angle plate 52 are respectively provided with a front-rear adjustment slot 5b with the longitudinal direction as the longitudinal direction and a left-right adjustment slot 5c with the left-right direction as the longitudinal direction, and when the horizontal plate portion 53 is stacked on the horizontal plate 52b, the intersection of the front-rear adjustment slot 5b and the left-right adjustment slot 5c communicates in the vertical direction, and as shown in FIG. 8(d), a fastening bolt 56 that holds and positions the stacked horizontal plate 52b and the horizontal plate portion 53 between the fastening nut 55 can be inserted. Therefore, the pin insertion hole 53a formed in the horizontal plate portion 53 through which the dowel pin 51 is inserted is positioned by the vertical adjustment slot 5a, the front-rear adjustment slot 5b, and the left-right adjustment hole 5c so as to be adjustable in the vertical direction and the horizontal directions of the front-rear and left-right directions with respect to the position of the wall surface WA into which the anchor bolt 54 is screwed.

[0064] 1 to 3, a floor finishing layer M is laid on the floor surface FL between the floor surface FL and the guide rail 4, and the height-adjustable metal fittings 3, the height of which is adjusted so that the guide rail 4 is positioned along a horizontal plane, are embedded in the floor finishing layer M. In this embodiment, the floor finishing layer M is a mortar layer M.

[0065] Mortar made of Portland cement containing fine aggregate such as silica sand has a certain strength and a small drying shrinkage rate, so even after a long period of time, the guide rail 4 is firmly supported by the hardened mortar layer M that is interposed between the floor surface FL with no gaps. Furthermore, when the height of the guide rail 4 is adjusted to a position, the height adjustment fitting 3 that holds and fixes the first angle plate 31 and the second angle plate 33 between the tightening bolt 35 and the tightening nut 36 is entirely buried in the dried and hardened mortar layer M, so there is no relative movement between the first angle plate 31 and the second angle plate 33.

[0066] Therefore, even if multiple heavy wall panels 2 are supported for a long period of time by the guide rails 44 arranged along a horizontal plane, the guide rails 4 will not bend downward or move downward toward the floor surface FL, and the interior wall 10 can be supported on the guide rails 4 that are aligned along the horizontal plane. That is, according to this embodiment, the mortar layer M that finishes the concrete floor surface FL can be used to prevent the guide rails 4, the height of which is adjusted by the height-adjustable metal fittings 3, from moving downward. Furthermore, since the multiple height-adjustable metal fittings 3 for supporting the interior wall 10 along the horizontal plane are embedded in the hardened mortar layer M and cannot be seen with the naked eye, there is no need to use materials or treatments to hide the height-adjustable metal fittings 3 that would detract from the aesthetic look of the room.

[0067] Hereinafter, a method for supporting a wall panel 2 upright using the above-mentioned wall panel support structure 1 will be described along with a process for connecting the upright supported wall panels 2 to construct an interior wall 10.

[0068] (A) A first step of arranging a plurality of height adjustment fittings 3 between a guide rail 4 and a floor surface FL

[0069] Here, the height-adjustable fittings 3 are placed below both ends and the middle of each of the multiple wall panels 2, 2... that make up the interior wall 10, so the width of the wall panel 2 is 840 mm, and multiple height-adjustable fittings 3 are placed at 420 mm intervals, which is 1 / 2 the width, on the floor surface FL along a straight line along which the interior wall 10 is constructed. Each height-adjustable fitting 3 is fixed to the floor surface FL by placing the second angle plate 33 with the second vertical plate 33a facing rearward on the floor surface FL, and screwing the anchor bolt 37 inserted through the second horizontal plate 33b into the floor surface FL.

[0070] As shown in Figure 5, the first vertical plate 31a is placed on the front of the second vertical plate 33a of the second angle plate 33 so that the first horizontal plate 31b of the first angle plate 31 faces above the second horizontal plate 33b fixed along the floor surface FL, and fastening nuts 36 are screwed onto fastening bolts 35 inserted through the first long holes 32 and second long holes 34 that communicate in the front-to-rear direction, so that the first angle plate 31 is temporarily held on the second angle plate 33 fixed to the floor surface FL.

[0071] Next, the flat bar 42 of the guide rail 4 is fixed with an adhesive or the like onto the flat surface of the first horizontal plates 31b of the multiple first angle plates 31 which are temporarily held by the multiple second angle plates 33, and the guide rail 4 is hung over the multiple height adjustment fittings 3, 3....

[0072] (B) A second step of adjusting the height of each of the first horizontal plates 31b of the plurality of height-adjustable fittings 3, 3... on the floor surface FL, and arranging the guide rail 4 along the horizontal plane on the floor surface FL.

[0073] Using a laser level, a laser beam is emitted in the left-right direction to mark out the horizontal plane, the vertical distance between the second horizontal plate 33b and the first horizontal plate 31b of each height-adjustable fitting 3 is adjusted so that the guide rail 4 is positioned along the horizontal plane, and the tightening bolts 35 are screwed and rotated at this adjusted position to fasten the first vertical plate 31a and the second vertical plate 33a between the tightening nuts 36 to fix them together. Height adjustment with this height-adjustable fitting 3 can be easily performed because the tightening bolts 35 are screwed and rotated from the front-rear direction.

[0074] (C) A third step in which the bottom surface of one wall panel 2 supported along the guide rail 4 is engaged with the rail 41a of the guide rail 4 and the wall panel 2 supported on the guide rail 4 is supported in an upright position along a vertical plane by an upright support bracket 5 connected to the framework WA.

[0075] In the third step, before at least the wall panel 2 is supported on the guide rail 4, the anchor bolt 54 movably inserted through the vertical adjustment slot 5a of the upright support bracket 5 is screwed into the wall surface WA near the upper side of each of the dowel holes 25a, 25b of the wall panels 2, 2, constituting the inner wall 10, to temporarily fix the upright support bracket 5. In addition, the tightening bolt 56 inserted through the front-rear adjustment slot 5b and the left-right adjustment slot 5c is also screwed into the tightening nut 55 so as to be movable within the front-rear adjustment slot 5b and the left-right adjustment slot 5c, and the horizontal plate 52b and the horizontal plate portion 53 are temporarily fixed.

[0076] Thereafter, the inner wall surface of the lowest crosspiece 22 of one wall panel 2 is engaged with a pair of rails 41a, 41a of the guide rail 4 arranged along a horizontal plane, and the wall panel 2 is supported on the guide rail 4 along the pair of rails 41a, 41a.

[0077] The height of the horizontal plate 52b of the L-shaped angle plate 52 can be fine-tuned by changing the insertion position of the vertical adjustment long hole 5a, through which the anchor bolt 54 is inserted. Next, the insertion position of the vertical adjustment long hole 5a of the anchor bolt 54 is adjusted so that the upper end of the wall panel 2, which is supported by the guide rail 4 whose height above the floor surface FL has been adjusted by the height adjustment bracket 3, is positioned at least below the horizontal plate 52b, and the L-shaped angle plate 52 is clamped between the anchor bolt 54 screwed into the wall surface WA and the wall surface WA, and fixed to the main body. Also, the tightening bolt 56 is inserted through the front-rear adjustment long hole 5b and the left-right adjustment long hole 5c so that the pin insertion hole 53a of the standing support bracket 5 is positioned above the dowel holes 25a, 25b drilled in the cross rail 22 of the wall panel 2, and the horizontal plate 52b and the horizontal plate portion 53 are clamped between the tightening nut 55, and the position of the pin insertion hole 53a drilled in the horizontal plate portion 53 is determined along the horizontal plane relative to the horizontal plate 52b of the L-shaped angle plate 52 fixed to the wall surface WA. By this positioning adjustment, the pin insertion hole 53a on the standing support bracket 5 side and the dowel holes 25a, 25b on the wall panel 2 side are aligned on the same vertical axis, so the dowel pin 51 is dropped from above into the pin insertion hole 53a and the dowel holes 25a, 25b, and the wall panel 2 supported by the guide rail 4 is supported in an upright position along the vertical plane.

[0078] Furthermore, in order to absorb horizontal assembly errors of the pin insertion hole 53a and the dowel holes 25a, 25b, the inner diameters of the pin insertion hole 53a and the dowel holes 25a, 25b can be made slightly larger than the outer diameter of the dowel pin 51, and the dowel pin 51 with an elastic adhesive such as an epoxy-based adhesive attached to its periphery can be inserted through them.

[0079] (D) A fourth step in which the bottom surface of the wall panel 2 (hereinafter, the connecting wall panel 2 will be referred to as the wall panel 2B) adjacent to the wall panel 2 (hereinafter, the connecting wall panel 2 will be referred to as the wall panel 2A) supported on the guide rail 4 in the third step is engaged with the rail 41a of the guide rail 4, the adjacent wall panels 2A and 2B are connected along the rail 41a, and then the connected wall panel 2B is supported in an upright position along a vertical plane by the upright support bracket 5.

[0080] In the third step, on the side of the wall panel 2A supported on the guide rail 4 where the wall panel 2B is to be connected, the joint post 6 is attached by fitting the post side flanges 62, 62 of the joint post 6 between the flanges 21a, 21b of the vertical bars 21 of the wall panel 2A, as shown in Figure 1. Next, the inner wall surface of the lowest horizontal rail 22 of the wall panel 2B adjacent to the side of the wall panel 2A is engaged with the pair of rails 41a, 41a to support the wall panel 2B on the guide rail 4, and while fitting the post side flanges 62, 62 of the joint post 6 between the flanges 21a, 21b of the vertical rails 21 of the wall panel 2B, the wall panel 2B is lifted diagonally upward toward the wall panel 2A to be connected, and at a position where the downward lock plate 26a of the wall panel 2B engages with the upward lock plate 26b of the wall panel 2A, the wall panel 2B is lowered onto the guide rail 4, and the downward lock plate 26a and the upward lock plate 26b are engaged to connect the wall panel 2B to the wall panel 2A.

[0081] In this connecting operation, the wall panel 2B is moved in the vertical and horizontal directions, but the horizontal plate portion 53 of the upright support bracket 5 is temporarily held so as to be movable beyond the distance of that movement, so that the upper end of the wall panel 2B does not interfere with the horizontal plate portion 53 and impede the connecting operation.

[0082] In addition, the wall panel 2B can be moved in the left-right direction because the post side flanges 62, 62 of the joint post 6 fit between the flanges 21a, 21b of the vertical bars 21 and the inner wall surface of the lowest horizontal bar 22 engages with a pair of rails 41a, 41a, and the downward locking plate 26a and the upward locking plate 26b engage reliably.

[0083] After connecting the wall panel 2B to the wall panel 2A, similarly to the third step, the upright support bracket 5 fixed to the wall surface WA above the wall panel 2B is positioned vertically and horizontally so that the pin insertion hole 53a is located vertically above the dowel holes 25a, 25b, and the dowel pin 51 is dropped from above into the pin insertion hole 53a and the dowel holes 25a, 25b, and the wall panel 2B connected to the wall panel 2A is also supported in an upright position along the vertical plane on the guide rail 4. As a result, the connected wall panels 2A, 2B are aligned and supported along the rail 41a and connected on the same vertical plane.

[0084] Similarly, the fourth step is repeated to arrange all of the wall panels 2, 2, ... constituting the interior wall 10 along the horizontal plane, and then, as shown in Figure 7, the gaps between the connected wall panels 2A, 2B are filled with joints 26 made of a silicone material or the like to complete the interior wall 10.

[0085] (E) The fifth step of laying a mortar layer M on the floor surface FL and burying all the height adjustment fittings 3 in the mortar layer M.

[0086] A mortar layer M is laid between the concrete floor surface FL and the guide rails 4, and all height-adjustable fittings 3 that adjust the height of the guide rails 4 are buried. As the mortar layer M dries and hardens, the height-adjustable fittings 3 are buried in the mortar layer M and cannot be seen from inside the room. Furthermore, even when the guide rails 4 support multiple heavy wall panels 2, 2..., they are firmly supported by the hardened mortar layer M between them and the floor surface FL, and will not drop or deform.

[0087] In the above-described embodiment, the wall panel 2 supported on the guide rails 4 is supported in an upright position along a vertical plane by the upright support bracket 5 fixed to the wall surface WA of the main body, but the upright support bracket 5 may be suspended from the ceiling surface of the main body to support the wall panel 2 along a vertical plane.

[0088] In addition, the guide portion of the guide rail 4 engages with the bottom surface of the wall panel 2 to align the multiple wall panels 2, 2... along the guide rail 4. However, the guide portion is not limited to a protrusion such as the rail 41a in the above embodiment, and may be a recess such as a groove that engages with the bottom surface of the wall panel 2.

[0089] In addition, in the above embodiment, a mortar layer is used as the floor finishing layer, but a concrete floor paint may be applied onto the floor surface to form the floor finishing layer.

[0090] Furthermore, the shape and structure of the wall panel 2 are merely examples, and the present invention can be applied to supporting wall panels of various shapes and structures. [Industrial Applicability]

[0091] The present invention is suitable for construction of an interior wall by connecting a plurality of wall panels supported in an upright position on guide rails. [Explanation of symbols]
