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 constitutes the wall surface of a building and has a fitting frame to which a shoji screen is attached and a panel frame that supports the fitting frame, wherein the panel frame has left and right vertical members and an upper member connected to each of the vertical members, and the fitting frame has left and right vertical frames and upper and lower frames connected to each of the vertical frames, and reinforcing members that can support the lower frames are detachably attached to each of the vertical members.

[0007] The method for constructing wall panels of the present invention is characterized by lifting up a wall panel having a panel frame having left and right vertical members and an upper member connected to each of the vertical members, a door 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, a shoji screen incorporated into the door frame, and reinforcing members that are detachably attached to the left and right vertical members and can support the lower frame, and after removing the reinforcing members from the left and right vertical members, placing the lower frame on the foundation of a building. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a wall panel and a wall panel installation method that can be transported with a shoji screen installed and installed in a building, thereby improving installation workability. [Brief explanation of the drawings]

[0010] 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. Furthermore, the wall panel 1 includes reinforcing materials 8 that 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. Note that Fig. 1 is an interior view of the wall panel 1 as seen from inside 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. Also, the pillar 110 shown in Fig. 3 is a pillar erected on the foundation of the building, and is positioned adjacent to the wall panel 1 when the wall panel 1 is installed in the building. 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.

[0011] [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, intermediate vertical members 26, 27, 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 intermediate vertical members 26, 27 are fixed to the inner peripheral side surfaces of the vertical members 22, 23 in a range from the lower surface of the horizontal member 24 to the lower ends of the vertical members 22, 23. The auxiliary vertical members 28, 29 are fixed to the inner peripheral side surfaces of the intermediate vertical members 26, 27. The intermediate vertical members 26, 27 and 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 crosspieces 25 form the outer periphery panel wooden frame, and the horizontal member 24, intermediate vertical members 26, 27, and auxiliary vertical members 28, 29 form the panel wooden frame around the sash. The surface 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 intermediate vertical members 26, 27, and to the exterior surfaces between the top member 21 and the horizontal member 24. Therefore, the surface material 30 is provided in a gate shape as a whole.

[0012] [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 reinforcing member 8 attached to this 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, 541 which are nail fin portions that protrude from the outer periphery of the window frame 5, and indoor mounting pieces 512, 522, 532, 542 which protrude from the indoor side of the window frame 5. The outdoor mounting pieces 511, 521, 531, 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, reinforcing material 8, and base 100. The indoor mounting pieces 512, 522, 532, 542 are parts that come into contact with and are screwed to the inner periphery of the panel frame 2, reinforcing material 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. Furthermore, the lower frame 52 has a hollow portion 525 formed above the exterior mounting piece 521, which is the nail fin portion, and straddling the exterior mounting piece 521 in the projection direction. A lower frame reinforcement member 56 is disposed in the hollow portion 525. The lower frame reinforcement member 56 is made of a metal such as aluminum or steel and is formed in a hollow cylindrical shape, with its outer surface formed along the inner surface of the hollow portion 525. The lower frame reinforcement member 56 is disposed in the projection direction (Z-axis direction) from a position below the outer rail 526 that guides the outer shoji screen 6A described below to a position below the inner rail 527 that guides the inner shoji screen 6B. In other words, the lower frame reinforcement member 56 is disposed in the projection direction, including the range from the outer rail 526 to the inner rail 527. The lower frame reinforcement member 56 is also inserted over substantially the entire length of the lower frame 52 in the longitudinal direction (X-axis direction) of the lower frame 52.

[0013] 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.

[0014] 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 facing surfaces of the horizontal member 24 and intermediate vertical members 26, 27, i.e., the panel frame 2, via the surface 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 intermediate vertical members 26, 27 and the vertical frames 53, 54, and function as spacers that fill the spaces between them.

[0015] 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.

[0016] [Reinforcement material] 1 to 4, the reinforcing member 8 includes a reinforcing piece 80 and a connecting metal fitting 81. The reinforcing piece 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 width dimension of the panel frame 2. The projected dimension of the reinforcing piece 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 from the exterior surface of the surface member 30 to the interior surfaces (interior facing surfaces) of the vertical members 22 and 23. The height dimension of the 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. In addition, the underside of the reinforcing wood 80 is flat, so the wall panel 1 can be erected by placing the underside of the reinforcing wood 80 on the floor of a pallet, for example.

[0017] The connecting fittings 81 are plate-shaped fittings that connect the left and right ends of the reinforcing wood 80 to the vertical members 22, 23 of the panel frame 2. The indoor facing surface of the reinforcing wood 80 is flush with the indoor facing surfaces of the vertical members 22, 23, and the connecting fittings 81 are positioned across these indoor facing surfaces and fixed to each indoor facing surface with screws 75. Countersunk holes that correspond to the screws 75 are formed in the connecting fittings 81. As shown in FIG. 2, the indoor mounting piece 522 of the lower frame 52 is temporarily fixed to the reinforcing wood 80 with a screw 59.

[0018] [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, intermediate vertical members 26, 27, and auxiliary vertical members 28, 29 are framed, and then the surface member 30 is attached to assemble the panel frame 2. Also at the panel frame 2 assembly factory, the reinforcing member 8 is 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.

[0019] [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 lifted 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 lifting the wall panel 1. Note that the shoji screen 6 is not shown in Figures 5 to 7. 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 reinforcing material 8 is removed from the panel frame 2. That is, the screws 59 that fastened the interior mounting piece 522 of the lower frame 52 to the reinforcing wood 80 are removed, and the screws 75 that fastened the connecting metal fittings 81 to the vertical members 22 and 23 are removed, and the reinforcing material 8, i.e., the reinforcing wood 80 and connecting metal fittings 81, are removed from the panel frame 2 to the interior side.

[0020] 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. In addition, the position of the wall panel 1 in the width direction, i.e., the X-axis direction, is determined by placing the wall panel 1 between the pillars 110, as shown in Figure 3. After the panel frame 2 is positioned, the indoor mounting piece 522 is fixed to the base 100 using a screw 59. In addition, the lower frame bracket 55 and the outdoor mounting piece 521 are fixed to the base 100 with 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.

[0021] [Effects of the first embodiment] According to this embodiment, the panel frame 2 is formed in a gate shape without a base member, allowing the wall panel 1 incorporating the terrace window 4, which has the window frame 5 placed directly on the base 100, to be assembled in a factory. The panel frame 2 is removably attached with the reinforcement member 8 supporting the bottom frame 52 of the terrace window 4. Therefore, the wall panel 1 can be transported to the construction site and the reinforcement member 8 can remain attached to the panel frame 2 until immediately before the wall panel 1 is lifted and installed on the base 100. This allows the wall panel 1 to be transported or lifted with the shoji screen 6 installed within the window frame 5, preventing deformation of the wall panel 1 during lifting. Furthermore, the bottom frame reinforcement member 56 is inserted into the hollow portion 525 of the bottom frame 52. Therefore, as shown in FIG. 6 , even when the reinforcement member 8 is removed, the bottom frame reinforcement member 56 can support the weight of the shoji screen 6 applied to the bottom frame 52. This prevents deformation of the wall panel 1 between the time the reinforcement member 8 is removed and the time the wall panel 1 is installed on the base 100. Therefore, the wall panel 1 can be lifted and attached to the 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 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.

[0022] The lower frame reinforcement 56 inserted into the hollow portion 525 of the lower frame 52 is arranged in the projection direction (Z-axis direction) from the position of the outer rail 526 to the position of the inner rail 527, so that the weight of the outer shoji screen 6A and the inner shoji screen 6B can be supported by the lower frame reinforcement 56 via the outer rail 526 and the inner rail 527. This allows the use of a window frame 5 made of synthetic resin, improving the thermal insulation performance of the terrace window 4. A lower frame reinforcement member 56 is inserted into the hollow portion 525 of the lower frame 52, and a lower frame bracket 55 is also attached to the underside of the lower frame 52, so that the weight of the outer shoji screen 6A, which is placed outside the base 100 and the reinforcement member 8, can also be supported by the base 100 and the reinforcement member 8 via the lower frame bracket 55 and the lower frame reinforcement member 56. As a result, a semi-exterior terrace window 4 can be constructed in which a shoji screen 6, which is heavy due to its large height and the use of triple glass as the face material 65, is incorporated into a window frame 5 made of synthetic resin. The connecting fittings 81 are detachably attached to the interior facing 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 the building, the reinforcing member 8 can be easily removed from the interior side.

[0023] [Second embodiment] Next, a wall panel 1B of a second embodiment will be described with reference to Fig. 8. Fig. 8 is a longitudinal cross-sectional view showing a main part of the wall panel 1B. In the wall panel 1B, the same or similar components as those of the wall panel 1 of the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted or simplified. The wall panel 1B includes a panel frame 2, a terrace window 4B, and a reinforcing material 8. The panel frame 2 and the reinforcing material 8 have the same configuration as in the first embodiment, and therefore a description thereof will be omitted. The terrace window 4B of the second embodiment includes a window frame 200 and a shoji screen 300. The shoji screen 300 has an outer shoji screen 300A and an inner shoji screen 300B. The window frame 200 is composed of an upper frame (not shown), a lower frame 202, and left and right vertical frames (not shown), and each frame material is made of an aluminum-resin composite material having aluminum profiles (metal frame materials) and resin frame materials.

[0024] The lower frame 202 is composed of a metal frame material 210 and a resin frame material 220. The metal frame material 210 is composed of a metal shaped material, specifically an aluminum extrusion shaped material, and has a hollow portion 211, an exterior mounting piece 212 which is a nail fin portion extending downward from the hollow portion 211, a projection piece 213 which extends from the hollow portion 211 toward the interior of the room, and two extension pieces 214, 215 which extend downward from the projection piece 213. The hollow section 211 is formed in a substantially rectangular shape with an upper surface, a lower surface, an exterior surface, and an interior surface, and an outer rail 216 and an inner rail 217 are formed on the upper surface. The interior surface of the hollow section 211 is formed diagonally downward from the lower end of the inner rail 217 toward the exterior, and a screw hole is formed at the joint between the lower end and the interior end of the lower surface. An exterior mounting piece 212 extends from this screw hole. The projected position of the exterior mounting piece 212 is further inward than the exterior surface of the hollow section 211, further outward than the extension piece 214, and slightly outward than the inner rail 217. A screw hole is also formed near the lower end of the outer rail 216 on the upper surface of the hollow section 211. The position of extension piece 214 in the projection direction is further inside the room than hollow portion 211 and inner rail 217, and the position of extension piece 215 in the projection direction is further inside the room than extension piece 214. Extension piece 215 is formed with an interior mounting piece 219 that is fixed to reinforcing wood 80 or base 100 with screws 59. Screw holes 218 are formed on the underside of projection piece portion 213, specifically in the connection between projection piece portion 213 and extension piece 214. Lower frame 202 is connected to the vertical frame by screws that are threaded through through holes in the vertical frame and into screw holes 218 formed in three locations. The resin frame material 220 is attached to the upper surface of the projection piece 213, and covers the metal frame material 210 exposed on the indoor side of the inner rail 217. In addition, between the outer rail 216 and the inner rail 217, a resin cover material 225 is attached to cover the indoor side portion of the outer shoji screen 300A in the closed position, that is, the portion exposed on the indoor side when the shoji screen 300 is closed.

[0025] The outer shoji screen 300A is configured with an upper frame (not shown), a lower frame 302, a door edge frame (not shown), an outer joint frame (not shown), and a surface material 305. The inner shoji screen 300B has the same configuration as the outer shoji screen 300A. Each frame is configured with an aluminum-resin composite material having an aluminum profile (metal frame material) and a resin frame material. For example, the lower frame 302 is configured with a metal frame material 310 and a resin frame material 320. The surface material 305 may be a single piece of glass, but in this embodiment it is configured with double-glazed glass.

[0026] In the wall panel 1B of the second embodiment, the reinforcing member 8 that supports the bottom frame 202 of the window frame 200 is detachably attached to the panel frame 2, so that the same effects as those of the first embodiment can be achieved.

[0027] [Third embodiment] Next, a wall panel 1C of a third embodiment will be described with reference to Fig. 9. Fig. 9 is a longitudinal cross-sectional view showing a main part of the wall panel 1C. In the wall panel 1C, the same or similar components as those of the wall panel 1 of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified. The terrace window 4C, which is a fixture attached to the wall panel 1C, comprises a window frame 5C and a shoji screen 6. The window frame 5C is a window frame made of synthetic resin for interior installation, and differs from the window frame 5 in that it does not have an exterior mounting piece. The bottom frame 52C of the window frame 5C has an interior mounting piece 522 and is provided with a hollow portion 525C. As in the first embodiment, the hollow portion 525C is formed in the range from the outer rail 526 to the inner rail 527 in the projection direction. A bottom frame reinforcement member 56C is inserted into this hollow portion 525C. Like the bottom frame reinforcement member 56, the bottom frame reinforcement member 56C is a hollow, tubular metal material, and its outer peripheral surface is formed along the inner peripheral surface of the hollow portion 525C. The expected dimensions of the reinforcing wood 80 of the reinforcing material 8 are such that they can support the entire underside of the lower frame 52C, since no outdoor mounting piece is provided that protrudes from the underside of the lower frame 52C.

[0028] In the wall panel 1C of the third embodiment, the reinforcing member 8 that supports the lower frame 52C is also detachably attached to the panel frame 2, so that the same effects as those of the first embodiment can be achieved.

[0029] [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. The reinforcing member 8 is not limited to one including wooden reinforcing pieces 80 and metal connecting fittings 81. For example, a metal reinforcing member having a long frame body and a fixing plate fixed to the vertical members 22, 23 may be used. Furthermore, the window frame 5 and shoji screen 6 are not limited to those using 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 those for terrace windows, but may also be those for terrace doors or back door doors, as long as the slats are placed directly on the foundation 100 of the building.

[0030] The connecting fittings 81 of the reinforcing material 8 are not limited to the configuration of the above embodiment, and may be configured, for example, as plates that connect the left and right end faces of the reinforcing wood 80 to the sides of the vertical members 22, 23, and may be any plate that is detachable from the vertical members 22, 23 and can connect the reinforcing wood 80 to the vertical members 22, 23. The bottom frame reinforcement members 56, 56C are not limited to aluminum or steel, but may be any material capable of reinforcing the synthetic resin bottom frames 52, 52C that support the weight of the shoji screen 6. The shape and dimensions of the bottom frame reinforcement members are not limited to those of the above-described embodiment. For example, in the first embodiment, the hollow portion 525 of the bottom frame 52 is formed in the range from the outer rail 216 to the inner rail 217 in the projection direction, but this range is not limited to this. The bottom frame reinforcement members are not limited to hollow cylindrical shapes. For example, they may have a structure in which a first hollow portion located below the outer rail 216 is connected to a second hollow portion located below the inner rail 217 by a connecting portion, or the first hollow portion and the second hollow portion may be formed separately. In other words, the hollow portions formed in the bottom frame and the bottom frame reinforcement members may be configured to prevent the bottom frame from deforming due to the weight of the outer and inner shoji screens.

[0031] [summary] The present invention is a wall panel that forms the wall surface of a building and has a fitting frame to which shoji screens are attached and a panel frame that supports the fitting frame, wherein the panel frame has left and right vertical members and an upper member connected to each of the vertical members, and the fitting frame has left and right vertical frames and upper and lower frames connected to each of the vertical frames, and reinforcing members that can support the lower frames are detachably attached to each of the vertical members. According to the present 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 rests directly on the base. Furthermore, because the bottom frame is supported by reinforcement members attached to the left and right vertical members of the panel frame, the wall panel can be transported to the construction site with the reinforcement members attached, and can be lifted. Therefore, at the construction site, the wall panel can be lifted with the shoji screen installed in the window frame, and the reinforcement members can be removed just before installation on the building foundation, after which the bottom frame can be installed on the foundation. This improves workability at the construction site and prevents the wall panel from deforming during lifting.

[0032] In the wall panel of the present invention, it is preferable that the door frame is a semi-exterior door frame, the lower frame has a nail fin portion that is fixed to the exterior surface of the building's frame, and the reinforcing material is arranged inside the room relative to the nail fin portion. According to the present invention, when the fitting frame is semi-exterior-mounted with nail fins, the reinforcing material supporting the sill is positioned on the interior side of the nail fins, so the size of the reinforcing material can be minimized. Also, semi-exterior fittings are installed on the interior side of the nail fins, so even if the reinforcing material is only located on the interior side of the nail fins, the weight of the fitting can be reliably supported during transportation or lifting.

[0033] In the wall panel of the present invention, it is preferable that the lower frame is made of synthetic resin, is positioned above the nail fin portion, has a hollow portion formed across the nail fin portion in the projection direction, and has a lower frame reinforcement material inserted into the hollow portion. According to the present invention, a hollow portion is formed in the synthetic resin sill, spanning the nail fin portion in the projection direction, and a sill reinforcement material is inserted into this hollow portion, so that the weight of the shoji screen can be supported by the sill reinforcement material, and even if the reinforcement material is only provided on the indoor side of the nail fin portion, the weight of the building material can be reliably supported during transportation or lifting. In addition, since a lower frame reinforcement is inserted into the lower frame, deformation of the wall panel can be prevented even when the reinforcement is removed and the wall panel is attached to the base.

[0034] In the wall panel of the present invention, it is preferable that the lower frame is constructed with a metal shaped member, and the shaped member has a hollow portion, a nail fin portion extending downward from the hollow portion, a projection portion extending from the hollow portion toward the interior of the room, and an extension portion extending downward from the projection portion. According to the present invention, the lower frame is constructed with metal shaped members that have a hollow portion, nail fin portions, projection portions, and extension portions, so the weight of the shoji screen can be supported by the reinforcing material and base via the lower frame. In particular, because the exterior portion of the lower frame is constructed with a hollow portion, even if the shoji screen is placed outside the nail fin portion, the weight of the shoji screen can be supported by the reinforcing material and base via the hollow portion and nail fin portion.

[0035] In the wall panel of the present invention, it is preferable that screw holes are formed in at least one of the projection piece portion or the extension piece, and that the lower frame and the left and right vertical frames are connected by screws screwed into the screw holes. According to the present invention, screw holes are formed in at least one of the projecting piece or the extending piece of the lower frame, so that even if the reinforcing material is removed, the weight of the shoji screen applied to the lower frame can be supported by the vertical frame via the screws threaded into the screw holes.

[0036] In the wall panel of the present invention, the lower frame is made of a synthetic resin material having an outer rail and an inner rail, and has a hollow portion formed to include the range from the outer rail to the inner rail in the projected direction, and it is preferable that a lower frame reinforcement material is inserted into the hollow portion. According to this invention, a hollow portion is formed in the sill, and this hollow portion is formed to include the area from the outer rail to the inner rail in the projection direction. Since the sill reinforcement is inserted into this hollow portion, the weight of the shoji screen guided by the outer rail and the inner rail can be supported by the sill reinforcement. Therefore, when the reinforcement is removed from the wall panel and attached to the base, the wall panel can be prevented from deforming.

[0037] The method for constructing wall panels of the present invention is characterized by lifting up a wall panel having a panel frame having left and right vertical members and an upper member connected to each of the vertical members, a door 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, a shoji screen incorporated into the door frame, and reinforcing members that are detachably attached to the left and right vertical members and can support the lower frame, and after removing the reinforcing members from the left and right vertical members, placing the lower frame on the foundation of a building. According to the present 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 rests directly on the base. Furthermore, because the bottom frame is supported by reinforcement members attached to the left and right vertical members of the panel frame, the wall panel can be transported to the construction site with the reinforcement members attached, and can be lifted. Therefore, at the construction site, the wall panel can be lifted with the shoji screen installed in the window frame, and the reinforcement members can be removed just before installation on the building foundation, after which the bottom frame can be installed on the foundation. This improves workability at the construction site and prevents the wall panel from deforming during lifting. [Explanation of symbols]
