Description

[Technical Field]

[0001] The present invention relates to a wall panel that constitutes a wall surface of a building and a method for installing the wall panel. [Background technology]

[0002] Patent Document 1 discloses a wall unit using a panel construction method in which a wall unit is manufactured in a factory, transported to a construction site, and attached to the building frame. The wall unit is made up of a frame that is attached to the building's framework and the fixtures that are installed within the frame. The fixtures can be various types of windows, such as sliding windows and inward-opening windows, and the frame is made up of the upper and lower members and left and right vertical members to which the window frames of the fixtures are attached.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-15713 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, there are some fixtures, such as terrace windows, terrace doors, and back door doors, that have a structure in which the bottom frame of the window or door frame is attached directly to the building's framework. When such fixtures are attached to the framework opening frame, the framework opening frame becomes a gate-shaped frame consisting only of a top member and left and right vertical members, and no bottom member can be provided. As a result, there is no bottom member to support the bottom frame of the fixture until the wall unit manufactured in the factory is transported to the construction site and attached to the building's framework, so the bottom frame of the fixture frame may deform under the weight of the shoji screen, which may cause the shoji screen to come off the frame. This meant that the wall unit with the fitting frame attached and the shoji screens (such as window screens and door frames) to be installed in the fitting frame had to be transported separately, and the shoji screens had to be attached to the fitting frame after the wall unit was installed in the building, which created the problem of reduced workability at the construction site.

[0005] An object of the present invention is to provide a wall panel and a method for installing the wall panel that can be transported with a shoji screen installed and installed in a building, thereby improving installation workability. [Means for solving the problem]

[0006] The wall panel of the present invention is a wall panel that comprises a window frame to which a shoji screen is attached and a panel frame that supports the window frame, and that forms the wall surface of a building. The panel frame comprises left and right vertical members, an upper member connected to each of the vertical members, and a surface member attached to the exterior surface of each of the vertical members. The window frame comprises left and right vertical frames, and an upper frame and a lower frame connected to each of the vertical frames. The lower frame has a base mounting portion that is placed on the foundation of the building, and a first reinforcing member that is positioned outside the base mounting portion and is capable of supporting the lower frame is detachably attached to the surface member.

[0007] The method for installing wall panels of the present invention is characterized by lifting up a wall panel having a panel frame having left and right vertical members, an upper member connected to each of the vertical members, and a face member attached to the exterior surface of each of the vertical members, a window frame having left and right vertical frames, an upper frame connected to each of the vertical frames, and a lower frame connected to each of the vertical frames and having a base mounting portion to be placed on the foundation of a building, a shoji screen incorporated into the window frame, and a first reinforcing member that is detachably attached to the face member and is positioned on the exterior side of the base mounting portion and can support the lower frame, and then placing the base mounting portion on the foundation of the building, and then removing the first reinforcing member from the face member.

[0008] The wall panel installation method of the present invention is characterized by lifting up a wall panel having: a panel frame having left and right vertical members, an upper member connected to each of the vertical members, and a face member attached to the exterior surface of each of the vertical members; a window frame having left and right vertical frames, an upper frame connected to each of the vertical frames, and a lower frame connected to each of the vertical frames and having a base mounting portion to be placed on the foundation of a building; a shoji screen incorporated into the window frame; a first reinforcing member that is detachably attached to the face member and is positioned on the exterior side of the base mounting portion and can support the lower frame; and a second reinforcing member that is detachably attached to each of the vertical members and can support the base mounting portion, and after removing the second reinforcing member from each of the vertical members, placing the base mounting portion on the foundation of the building, and then removing the first reinforcing member from the face member.

DETAILED DESCRIPTION OF THE INVENTION

[0011] A first embodiment of the present invention will be described below with reference to the drawings. 1 to 3, the wall panel 1 of this embodiment is handled as a single structure when attached to a building, and includes a panel frame 2 and a terrace window (floor window) 4, which is a fixture. The wall panel 1 also includes a first reinforcing member 7 and a second reinforcing member 8, which are used when the wall panel 1 is transported from a factory where the wall panel 1 is manufactured to a construction site and then installed on the building. FIG. 1 is an interior view of the wall panel 1 as seen from the interior side of the room, and FIGS. 2 and 3 are longitudinal and transverse cross-sectional views of the wall panel 1. In the cross-sectional views of FIGS. 2 and 3, hatching indicating the cross sections of the window frame 5 and the shoji screen 6 has been omitted. The pillar 110 shown in FIG. 3 is a pillar erected on the foundation of a building and will be positioned adjacent to the wall panel 1 when the wall panel 1 is installed in the building. As shown in FIG. 3, the wall panel 1 of this embodiment is a wall panel for a large wall, in which a facing material 30 is attached to the exterior side of the pillar 110 to conceal the pillar 110. For this reason, although not shown, panels such as gypsum board are attached to the interior sides of the wall panel 1, pillar 110, and beams, and are finished with wallpaper or the like. In the following description, the left-right direction of the wall panel 1 is defined as the X-axis direction, the up-down direction of the wall panel 1 is defined as the Y-axis direction, and the projection direction (indoor / outdoor direction) of the wall panel 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0012] [Panel Frame] The panel frame 2 is configured in a gate shape and includes an upper member 21 made of wood (solid material), vertical members 22, 23, horizontal members 24, vertical bars 25, and auxiliary vertical members 28, 29, and a surface member 30 is attached to the exterior surface. The upper ends of the vertical members 22 and 23 abut against the undersides of the left and right ends of the upper member 21, and the upper member 21 and the vertical members 22 and 23 are framed by horizontal members. A horizontal member 24 is hung between the vertical members 22 and 23, and a vertical crosspiece 25 is hung between the upper member 21 and the horizontal member 24. The auxiliary vertical members 28, 29 are fixed to the inner peripheral side surfaces of the vertical members 22, 23. The auxiliary vertical members 28, 29 have shorter projected dimensions than the upper member 21, the vertical members 22, 23, and the horizontal member 24. The upper member 21, vertical members 22, 23, and vertical bars 25 form the outer periphery panel wooden frame, and the horizontal member 24 and auxiliary vertical members 28, 29 form the panel wooden frame around the sash. The face material 30 is made of particle board and is attached with adhesive or the like to the exterior surfaces of the vertical members 22, 23 and to the exterior surfaces between the top member 21 and the horizontal member 24. Therefore, the face material 30 is attached to the exterior surfaces of the vertical members 22, 23, and in this embodiment, it is also attached to the exterior surface of the top member 21, forming a gate-like structure as a whole. Furthermore, the face material 30 extends outward more than the vertical members 22, 23 in the left-right direction (X-axis direction) and extends upward more than the top member 21 in the upward direction, and is configured so that it can be attached to the exterior surfaces of pillars 110 and beams (not shown) of a building. On the indoor side of the face material 30, a heat insulating material 90 is attached with adhesive or the like to the outer periphery of the vertical members 22, 23. As shown in Fig. 3, the heat insulating material 90 is configured so that it can be placed in the space between the vertical members 22, 23 and the pillar 110. Also, on the indoor side of the face material 30, a heat insulating material 91 is attached with adhesive or the like to the space partitioned by the top member 21, horizontal member 24, vertical members 22, 23, and vertical crosspiece 25. By using the wall panel 1 configured in this manner, it is possible to achieve a large wall fit in which the exterior surfaces of the pillars 110 and beams can be hidden by the surface material 30.

[0013] [Terrace window] The terrace window 4, which is a fixture, is arranged in an opening defined by a gate-shaped panel frame 2 and a first reinforcing member 7 and a second reinforcing member 8 attached to the panel frame 2. The terrace window 4 is a sliding window equipped with a window frame 5, which is a fitting frame, and a shoji screen 6, and is a French window whose bottom end is at floor level of the building. The window frame 5 is composed of an upper frame 51, a lower frame 52, and left and right vertical frames 53 and 54. The window frame 5 of this embodiment is made of synthetic resin, and is formed by cutting the ends of each frame 51 to 54 at a 45-degree angle and welding the small edges together. As shown in Figures 2 and 3, each of the frames 51 to 54 has outdoor mounting pieces 511, 521, 531, and 541, which are nail fin portions that protrude from the outer periphery of the window frame 5, and indoor mounting pieces 512, 522, 532, and 542 that protrude from the indoor side of the window frame 5. The outdoor mounting pieces 511, 521, 531, and 541, which are nail fin portions, are parts that come into contact with and are screwed to the outdoor surfaces of the panel frame 2, the second reinforcing member 8, and the base 100. The indoor mounting pieces 512, 522, 532, and 542 are parts that come into contact with and are screwed to the inner periphery of the panel frame 2, the second reinforcing member 8, and the top surface of the base 100. 2, a holding piece 523 having a generally L-shaped cross section is formed on the underside of the lower frame 52 to hold the outdoor end of the lower frame bracket 55 that reinforces the lower frame 52. The underside of the lower frame 52 on the indoor side of the outdoor mounting piece 521 forms a base mounting portion 524 that is placed on the base 100 as described below.

[0014] The lower frame bracket 55 includes a support piece 551 arranged along the underside of the lower frame 52, and a fixing piece 552 extending downward from the indoor end of the support piece 551. A groove opening to the upper surface is formed in the support piece 551, and a sealant is attached to this groove that abuts against the underside of the lower frame 52, sealing the gap between the lower frame bracket 55 and the lower frame 52 and improving watertightness. The lower frame bracket 55 is attached to the lower frame 52 by, for example, adhering the upper surface of the support piece 551 to the underside of the lower frame 52 with double-sided tape. The length of the lower frame bracket 55 in the X-axis direction is slightly shorter than the length of the lower frame 52.

[0015] The exterior mounting pieces 511, 531, 541 of the upper frame 51 and the vertical frames 53, 54 are fixed with screws 58 to the exterior surfaces (exterior facing surfaces) of the horizontal members 24 and vertical members 22, 23, i.e., the panel frame 2, via the face member 30. The interior mounting pieces 512, 532, 542 are also fixed to the panel frame 2 with screws (not shown). Therefore, the panel frame 2 functions as a support frame that supports the window frame 5. The auxiliary vertical members 28, 29 are arranged between the vertical members 22, 23 and the vertical frames 53, 54, and function as spacers that fill the spaces between them.

[0016] The shoji screen 6 comprises an outer shoji screen 6A and an inner shoji screen 6B. The outer shoji screen 6A comprises an upper frame 61, a lower frame 62, a door edge frame 63, an outer joint frame (not shown), and a surface material 65. The inner shoji screen 6B, like the outer shoji screen 6A, comprises an upper frame 61, a lower frame 62, a door edge frame 63, an inner joint frame 64, and a surface material 65. Each of the frames 61 to 64 comprises a frame body made of synthetic resin and a synthetic resin edge. The frame body is framed by welding together the edges of each frame, which have been cut at a 45-degree angle. The face material 65 may be a single pane of glass or double pane glass, but in this embodiment it is made of triple pane glass.

[0017] [First reinforcement material] As shown in FIGS. 2 and 4 , the first reinforcing member 7 includes a first reinforcing wood 70 and a first connecting metal fitting 71. The first reinforcing wood 70 is a piece of wood (square timber) with a rectangular cross section, and its longitudinal dimension is greater than the width of the terrace window 4 and less than the distance between the columns 110. The projected dimension of the first reinforcing wood 70, i.e., its dimension in the Z-axis direction, is set so that when the indoor surface of the first reinforcing wood 70 is abutted against the indoor-side mounting piece 522, the outdoor surface of the first reinforcing wood 70 substantially coincides with the outdoor surface of the sill 52. The height dimension of the first reinforcing wood 70, i.e., its dimension in the Y-axis direction, is substantially the same as the projected dimension of the first reinforcing wood 70. Note that the projected dimension and height dimensions of the first reinforcing wood 70, i.e., the dimensions in the X-axis and Y-axis directions, are not limited to the same dimensions as in this embodiment, and may be set taking into consideration the strength required of the first reinforcing wood 70 and dimensional restrictions on the wall panel 1 during transportation.

[0018] The first connecting fittings 71 are fittings that connect the left and right ends of the first reinforcing wood 70 to the face material 30 of the panel frame 2. As shown in Figure 4, the first connecting fittings 71 include a side fixing portion 72, an upper surface fixing portion 73, and an exterior surface fixing portion 74. The side fixing portions 72 extend downward from the side ends of the top fixing portion 73 and are fixed to the left and right end faces of the first reinforcing wood 70 with screws 75. The top fixing portion 73 is fixed to the top faces of the left and right ends of the first reinforcing wood 70 with screws 75. The exterior fixing portion 74 extends upward from the indoor end of the top fixing portion 73 and is fixed to the face material 30 with screws 75. For this reason, the face material 30 is set to a thickness dimension that allows the screws 75 to be threaded in to attach the first reinforcing material 7. The screws 75 are half-threaded countersunk wood screws, and the first connecting fitting 71 has countersunk holes that correspond to the screws 75. The position of the first reinforcing wood 70 in the prospective direction (Z-axis direction) is further outdoors than the outdoor mounting piece 521 and the fixed piece 552, that is, further outdoors than the base mounting portion 524, and is configured so that the lower frame 52 can be supported outdoors than the outdoor mounting piece 521. In this embodiment, a wooden spacer 76 is fixed with double-sided tape or the like to the upper surface of the first reinforcing wood 70. The spacer 76 is positioned closer to the room than the holding piece 523, and the spacer 76 abuts against the underside of the support piece 551, preventing the holding piece 523 from abutting against the upper surface of the first reinforcing wood 70 and causing deformation.

[0019] [Second reinforcement material] 1 to 4, the second reinforcing member 8 includes a second reinforcing wood 80 and a second connecting metal fitting 81. The second reinforcing wood 80 is a piece of wood (square timber) with a rectangular cross section, and its longitudinal dimension, i.e., its dimension in the X-axis direction, is approximately the same as the length dimension of the first reinforcing wood 70. The projected dimension of the second reinforcing wood 80, i.e., its dimension in the Z-axis direction, is approximately the same as the projected dimension of the panel frame 2, specifically, the length dimension from the exterior surface of the facing member 30 to the interior surfaces (interior facing surfaces) of the vertical members 22 and 23. The height dimension of the second reinforcing wood 80 is set to ensure the strength necessary to support the terrace window 4, while also taking into consideration dimensional restrictions during transportation of the wall panel 1. Furthermore, the undersides of the first reinforcing wood 70 and the second reinforcing wood 80 are formed flush, that is, positioned on the same plane without any steps, so the wall panel 1 can be erected by placing the undersides of the first reinforcing wood 70 and the second reinforcing wood 80 on the floor of a pallet, for example.

[0020] The second connecting fittings 81 are plate-shaped fittings that connect the vicinity of both the left and right ends of the second reinforcing wood 80 to the vertical members 22, 23 of the panel frame 2. The interior surface of the second reinforcing wood 80 is flush with the interior surfaces of the vertical members 22, 23, and the second connecting fittings 81 are positioned across these interior surfaces and fixed to each interior surface with screws 75. Countersunk holes that correspond to the screws 75 are formed in the second connecting fittings 81. As shown in FIG. 2, the indoor mounting piece 522 of the lower frame 52 is temporarily fixed to the second reinforcing wood 80 with a screw 59 .

[0021] [Wall panel manufacturing method] The process of assembling the wall panel 1 at the factory will be explained. First, the window frame 5 and shoji screens 6 that make up the terrace window 4 are assembled at the sash manufacturing factory. This assembly method is the same as that for a general terrace window 4, so an explanation will be omitted. The assembled window frame 5 and shoji screens 6 are transported to the panel frame 2 assembly factory. At the panel frame 2 assembly factory, the top member 21, vertical members 22, 23, horizontal member 24, vertical bars 25, and auxiliary vertical members 28, 29 are framed, and then the face member 30 and insulating materials 90, 91 are attached to assemble the panel frame 2. Also at the panel frame 2 assembly factory, the first reinforcing member 7 and the second reinforcing member 8 are fixed to the panel frame 2 with screws 75, and the window frame 5 is fixed to the panel frame 2 with screws 58, 59 to assemble the wall panel 1. The wall panels 1 assembled as described above are stacked flat on a transport pallet with spacers between them and transported to the construction site by truck or similar. The shoji screen 6 may be assembled into the window frame 5 at the assembly factory for the panel frame 2, or may be assembled into the window frame 5 at the construction site. Therefore, there are cases where the wall panel 1 with the shoji screen 6 assembled therein is transported by truck or similar, and cases where the wall panel 1 and the shoji screen 6 are transported separately by truck or similar.

[0022] [Wall panel installation method] A construction method for installing the wall panel 1 on a building will be described with reference to FIGS. At the construction site, the wall panel 1 is hoisted using a crane or the like. If the wall panel 1 and the shoji screen 6 are transported separately, the shoji screen 6 can be assembled into the window frame 5 before hoisting the wall panel 1. Note that the shoji screen 6 and the heat insulating materials 90 and 91 are not shown in Figures 5 to 8. As shown in Figure 5, the lifted wall panel 1 is moved above the foundation 100 of the building. The foundation 100 is placed on a base 101, and a floor material 102 is placed on part of the upper surface of the foundation 100. Next, as shown in Figure 6, with the wall panel 1 lifted up, the second reinforcing member 8 is removed from the panel frame 2. That is, the screws 59 that fastened the interior mounting piece 522 of the bottom frame 52 to the second reinforcing wood 80 and the screws 75 that fastened the second connecting fitting 81 to the vertical members 22 and 23 are removed, and the second reinforcing member 8, i.e., the second reinforcing wood 80 and the second connecting fitting 81, are removed from the panel frame 2 to the interior side.

[0023] Next, as shown in Figure 7, the wall panel 1 lifted by the crane is placed on the base 100. At this time, the position of the wall panel 1 in the prospective direction is determined by abutting the lower frame bracket 55 and the outdoor mounting piece 521, which is the nail fin portion, on the outdoor surface of the base 100. Therefore, the base mounting portion 524 of the lower frame 52 is placed on the upper surface of the base 100. Furthermore, the position of the wall panel 1 in the width direction, i.e., the X-axis direction, is determined as shown in Figure 3, by placing the wall panel 1 between the pillars 110, with the left and right insulation materials 90 abutting the side surfaces of the pillars 110, and the face material 30 covering approximately half of the outdoor surface of the pillars 110. After the panel frame 2 is positioned, the indoor mounting piece 522 is fixed to the base 100 using a screw 59.

[0024] Next, as shown in Figure 8, the first reinforcing member 7 is removed from the panel frame 2. That is, the screws 75 that attached the first connecting fittings 71 to the face material 30 are removed, and the first reinforcing member 7, i.e., the first reinforcing wood 70 and the first connecting fittings 71, are removed from the panel frame 2 to the outside of the room. Thereafter, the lower frame bracket 55 and the outdoor mounting piece 521 are fixed to the base 100 with the screws 58. Furthermore, the wall panel 1 is attached to the base 100 or the like using hold-down hardware, anchor bolts, double-ended tension bolts, etc. After that, exterior wall materials can be placed on the outdoor side of the wall panel 1, and finishing work can be performed by sealing.

[0025] [Effects of the first embodiment] According to this embodiment, the panel frame 2 is formed in a gate shape without a base material, so that the wall panel 1 incorporating the terrace window 4, in which the window frame 5 is placed directly on the base 100, can be assembled in a factory. Furthermore, because the first reinforcing member 7 is positioned on the outdoor side of the base mounting portion 524 of the sill 52, the base mounting portion 524 can be placed on and fixed to the base 100 with the first reinforcing member 7 attached. Therefore, the first reinforcing member 7 can be attached to the panel frame 2 until the wall panel 1 is lifted and installed on the base 100, so that the wall panel 1 can be lifted with the shoji screen 6 installed in the window frame 5, and deformation of the wall panel 1 during lifting can be prevented. The wall panel 1 can be assembled in a factory and transported to a construction site to be attached to a building, and the wall panel 1 can also be lifted and attached to a building with the shoji screen 6 already installed in the window frame 5, improving workability at the construction site and enabling the construction of a high-quality wall surface. Also, the wall panel 1 can be transported from the factory to the construction site with the shoji screen 6 already installed in the window frame 5, in which case there is no need to install the shoji screen 6 in the window frame 5 at the construction site, further improving workability at the construction site.

[0026] The first connecting fitting 71 of the first reinforcing member 7 is removably attached to the surface member 30, so that even when the wall panel 1 is installed between the pillars 110, the first reinforcing member 7 can be easily removed from the outside of the room. Furthermore, since the first connecting fitting 71 is fixed to the panel 30 with a screw 75 and is not fixed to the vertical members 22, 23, the width dimensions of the vertical members 22, 23 can be set to the minimum width dimensions required to fix the vertical frames 53, 54 and the second connecting fitting 81, thereby reducing costs. Furthermore, since the heat insulating material 90 is attached to the indoor side of the panel 30, even if the tip of the screw 75 that fixes the first connecting fitting 71 to the panel 30 penetrates the panel 30, the tip of the screw 75 can be buried and hidden within the heat insulating material 90.

[0027] The provision of the second reinforcing member 8 in addition to the first reinforcing member 7 further increases the strength of the sill 52. This allows the wall panel 1 to be transported from the factory where it is manufactured to the construction site with the shoji screen 6 assembled into the window frame 5. The second connecting fittings 81 are removably attached to the interior surfaces of the left and right vertical members 22, 23, so that even when the wall panel 1 is installed between the pillars 110 of a building, the second reinforcing member 8 can be easily removed from the interior side. The dimension in the prospective direction from the exterior surface of the first reinforcing member 7 to the interior surface of the second reinforcing member 8 is approximately the same as the dimension in the prospective direction from the exterior surface of the window frame 5 to the interior surface of the panel frame 2. Therefore, when the wall panel 1 is transported by truck or the like, the first reinforcing member 7 and the second reinforcing member 8 do not protrude from the exterior surface or the interior surface of the wall panel 1, and transportation efficiency is improved when the wall panel 1 is transported flat, for example.

[0028] [Second embodiment] Next, a wall panel 1B of a second embodiment will be described with reference to Fig. 9. Fig. 9 is a cross-sectional view showing the wall panel 1B. In the wall panel 1B, components that are the same as or similar to those of the wall panel 1 of the first embodiment are given the same reference numerals, and descriptions thereof will be omitted or simplified. The wall panel 1B includes a panel frame 2B, a back door 4B, a first reinforcing member 7, and a second reinforcing member 8. The first reinforcing member 7 and the second reinforcing member 8 have the same configuration as in the first embodiment, and therefore a description thereof will be omitted.

[0029] The panel frame 2B has the same configuration as the panel frame 2 of the first embodiment, but differs in that second vertical members 26, 27 are added to the outer periphery of the heat insulating material 90, and the upper member 21 is attached across the second vertical members 26, 27. Note that horizontal members may be added as appropriate between the vertical member 22 and the second vertical member 26, or between the vertical member 23 and the second vertical member 27. The back door 4B of the second embodiment includes a door frame 200 and a door 300 that is openably and closably connected to the door frame 200 by a hinge 250. Therefore, in the back door 4B, the door frame 200 is the window frame of the present invention, and the door 300 is a shoji screen. The door frame 200 is composed of an upper frame (not shown), a lower frame (not shown), a vertical frame 203 on the door tip side, and a vertical frame 204 on the hanging side. The vertical frames 203 and 204 are provided with outdoor mounting pieces 211 which are nail fin portions, and the outdoor mounting pieces 211 are fixed to the face material 30 and the vertical members 22 and 23 with screws 58.

[0030] In the wall panel 1B of the second embodiment, the first reinforcing member 7 supporting the lower frame of the door frame 200 is removably attached to the surface member 30, and the second reinforcing member 8 is removably attached to the vertical members 22, 23, so that the same effects as those of the first embodiment can be achieved. Because the panel frame 2B has the additional second vertical members 26, 27, the insulating material 90 can be placed between the vertical members 22, 23 and the second vertical members 26, 27 and attached with adhesive or the like, thereby stably holding the insulating material 90. Furthermore, because the second vertical members 26, 27 can be placed in contact with the pillars 110, the wall panel 1B can be easily positioned in the left-right direction (X-axis direction), and the second vertical members 26, 27 can also be fixed to the pillars 110, base 100, etc., improving the fixing strength of the wall panel 1B.

[0031] [Variations] The present invention is not limited to the configurations described in the above embodiments, and modifications within the scope of achieving the object of the present invention are included in the present invention. For example, in the above embodiment, two reinforcing members, the first reinforcing member 7 and the second reinforcing member 8, are provided on the panel frame 2. However, a wall panel with only the first reinforcing member 7 attached may be transported from a factory to a construction site, lifted by a crane, and installed on the base 100. In this case, the same effects as those of the wall panel 1 of the above embodiment can be achieved, and further, because there is no need to remove the second reinforcing member 8, the work of installing the wall panel on the base 100 can be easily performed.

[0032] The first reinforcing member 7 and the second reinforcing member 8 are not limited to those including wooden first reinforcing wood 70 and second reinforcing wood 80 and metal first connecting metal fittings 71 and second connecting metal fittings 81. For example, metal reinforcing members having a long frame body and fixing plates that are fixed to the face member 30 and the vertical members 22, 23 may also be used. Furthermore, the window frame 5 and the shoji screen 6 are not limited to frames and stiles made of synthetic resin or composite shapes of aluminum and synthetic resin, but may be made of metal such as extruded aluminum, or may use wooden frames and stiles. Furthermore, the fittings, i.e., the window frame and shoji screen, are not limited to terrace windows 4 and back door 4B, but may be fittings whose sills are placed directly on the foundation 100 of the building. Furthermore, the wall panel is not limited to a wall panel for large wall installation in which the face material 30 is fixed to the exterior surface of the pillars 110 or beams, but may also be a wall panel for solid wall installation that fits between the pillars 110. That is, in a wall panel for solid wall installation, similar to the wall panel 1B, the face material 30 is placed across the vertical members 22, 23 to which the window frame is attached and the second vertical members 26, 27 that are placed along the pillars 110, and the first reinforcing member 7 is detachably attached to this face material 30.

[0033] [summary] The present invention is a wall panel that forms the wall surface of a building and has a window frame to which a shoji screen is attached and a panel frame that supports the window frame, wherein the panel frame has left and right vertical members, an upper member connected to each of the vertical members, and a surface member attached to the exterior surface of each of the vertical members, the window frame has left and right vertical frames and an upper frame and a lower frame connected to each of the vertical frames, the lower frame has a base mounting portion that is placed on the foundation of the building, and a first reinforcing member that is positioned outside the base mounting portion and can support the lower frame is detachably attached to the surface member. According to this invention, the panel frame supporting the window frame has left and right vertical members and a top member, but no bottom member, making it possible to manufacture wall panels incorporating terrace windows in which the window frame is placed directly on the base. Furthermore, the first reinforcing members attached to the left and right vertical members of the panel frame are positioned outside the base mounting portion of the bottom frame, so the wall panel can be lifted with the first reinforcing members attached and its bottom frame placed on the building's foundation. Therefore, at the construction site, the wall panel can be lifted and installed on the building's foundation with the shoji screen installed in the window frame, improving workability at the construction site and preventing the wall panel from deforming during lifting. Furthermore, because the first reinforcing member is detachably attached to the face material, there is no need to attach the first reinforcing member to the vertical frame of the panel frame that secures the vertical frame of the window frame. This allows the width dimension of the vertical frame of the panel frame to be minimized, resulting in cost reduction.

[0034] In the wall panel of the present invention, it is preferable that the face material is attached to the exterior surface of each of the vertical members and extends outward from the vertical members, and that the first reinforcing member comprises a first connecting fitting that is detachably attached to the face material on the outer periphery of each of the vertical members. According to the present invention, the first connecting fitting of the first reinforcing material is removably attached to the surface material extending on the outer periphery of the left and right vertical members, so that even if the wall panel is installed, for example, between the pillars of a building, the first reinforcing material can be easily removed from the outside of the room.

[0035] In the wall panel of the present invention, it is preferable that a second reinforcing member capable of supporting the base mounting portion is detachably attached to each of the vertical members. According to the present invention, by providing a second reinforcing member in addition to the first reinforcing member, the support strength of the lower frame can be improved, and the wall panel can be transported from the factory to the construction site with a terrace window screen, which is heavy due to its large height, installed in the window frame.

[0036] In the wall panel of the present invention, the second reinforcing member preferably includes a second connecting metal fitting that is detachably attached to the indoor surface of each of the vertical members. According to the present invention, the second connecting fittings of the second reinforcing material are removably attached to the interior surfaces of the left and right vertical members, so that even if the wall panel is installed, for example, between the pillars of a building, the second reinforcing material can be easily removed from the interior side.

[0037] In the wall panel of the present invention, it is preferable that a heat insulating material is attached to the indoor side of the face material and on the outer periphery of the vertical member, and that the face material extends outward beyond the heat insulating material and is fixed to the outdoor surface of the building pillar. According to the present invention, the insulation material is attached to the indoor side of the facing material, thereby improving the insulation performance of the wall panel. In addition, since the facing material extends outward from the insulation material and is fixed to the outdoor surface of the building pillar, a large wall installation can be achieved.

[0038] The method for installing wall panels of the present invention is characterized by lifting up a wall panel having a panel frame having left and right vertical members, an upper member connected to each of the vertical members, and a face member attached to the exterior surface of each of the vertical members, a window frame having left and right vertical frames, an upper frame connected to each of the vertical frames, and a lower frame connected to each of the vertical frames and having a base mounting portion to be placed on the foundation of a building, a shoji screen incorporated into the window frame, and a first reinforcing member that is detachably attached to the face member and is positioned on the exterior side of the base mounting portion and can support the lower frame, and then placing the base mounting portion on the foundation of the building, and then removing the first reinforcing member from the face member. According to the present invention, the first reinforcing member is detachably attached to the facing member, so that deformation of the wall panel can be prevented when the wall panel is transported from the factory to the construction site and then lifted by a crane or the like at the construction site. Furthermore, because the first reinforcing member is positioned on the exterior side of the base mounting portion of the sill, the wall panel can be lifted with the first reinforcing member attached and the sill can be placed on the building's foundation, and the wall panel can be lifted and installed on the building's foundation with the shoji screen installed in the window frame. This improves workability at the construction site.

[0039] The wall panel installation method of the present invention is characterized by lifting up a wall panel having: a panel frame having left and right vertical members, an upper member connected to each of the vertical members, and a face member attached to the exterior surface of each of the vertical members; a window frame having left and right vertical frames, an upper frame connected to each of the vertical frames, and a lower frame connected to each of the vertical frames and having a base mounting portion to be placed on the foundation of a building; a shoji screen incorporated into the window frame; a first reinforcing member that is detachably attached to the face member and is positioned on the exterior side of the base mounting portion and can support the lower frame; and a second reinforcing member that is detachably attached to each of the vertical members and can support the base mounting portion, and after removing the second reinforcing member from each of the vertical members, placing the base mounting portion on the foundation of the building, and then removing the first reinforcing member from the face member. According to the present invention, the provision of a second reinforcing member in addition to the first reinforcing member improves the support strength of the sill, allowing the wall panel to be transported from a factory to a construction site with a terrace window screen, which is heavy due to its large height, installed in the window frame. Furthermore, the second reinforcing member is removed while the first reinforcing member remains attached, preventing the wall panel from deforming when lifted by a crane or other device. Furthermore, because the first reinforcing member is positioned outside the base mounting portion of the sill, with the second reinforcing member removed, the wall panel can be lifted with the first reinforcing member attached and the sill placed on the building's foundation. Furthermore, the wall panel can also be lifted with the sill installed and installed on the building's foundation. This improves workability at the construction site. [Explanation of symbols]
