Description

[Technical Field]

[0001] The present disclosure relates to wall panels. [Background technology]

[0002] Conventionally, a known construction method for constructing building walls is a framework formed using beams and other horizontal members and columns, and then fixing paneling to the framework. This construction method requires a large number of steps at the construction site, such as erecting columns and joining beams to the columns, and also has the problem of being prone to variations in construction quality. For example, Patent Document 1 below discloses an architectural wall panel comprising a horizontal frame member equivalent to a beam or girder, an embedded frame joined to the underside of the horizontal frame member, and a surface member installed across the front of the horizontal frame member and the embedded frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-125200 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, on one side of the horizontal frame material of such architectural wall panels in the panel thickness direction, joint objects such as beams that form the upper end of a partition wall, beams that support the ceiling substructure, floor beams and joists that form the floor substructure of the upper floor, etc. In such cases, at the construction site, it is necessary to perform notching or the like on the face material fixed to one side of the horizontal frame material in the panel thickness direction so as to surround the joint objects, and further improvement is desired.

[0005] The present disclosure has been made in consideration of the above-mentioned circumstances, and aims to provide a wall panel that can improve workability. [Means for solving the problem]

[0006] In order to achieve the above object, the wall panel according to the present disclosure comprises a panel frame body having a cross member constituting an upper end, a plurality of pillar members having their upper ends joined to the cross member, and lower cross members joined to the lower ends of the pillar members, and an upper end side member whose upper portion is fixed to one surface of the cross member in the panel thickness direction and which is provided so as to extend in the panel width direction at the upper end side of one surface of the panel frame body in the panel thickness direction, and which is characterized in that the upper end side member is provided with a receiving recess for receiving the end of the object to be joined which is to be joined to the one surface of the cross member in the panel thickness direction. [Effects of the Invention]

[0007] The wall panel according to the present disclosure has the above-described configuration, thereby enabling improved workability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiment, directions such as the up-down direction will be described based on a state in which an example of a wall panel according to this embodiment is installed. 1 to 6 are diagrams schematically showing an example of a wall panel according to this embodiment and an example of a construction procedure for the wall panel.

[0010] As shown in FIG. 3 , the wall panel 1 according to this embodiment includes a panel frame 10 having a cross member 11 constituting the upper end, multiple columns 12 whose upper ends are joined to the cross member 11, and lower cross members 14 joined to the lower ends of the columns 12. This configuration eliminates the need to join the columns 12 and cross members 11 that constitute the structural members at the construction site, improving workability. The wall panel 1 includes an upper side member 23 whose upper portion is fixed to one surface of the cross member 11 in the panel thickness direction (wall thickness direction) and which is provided at the upper end of one surface of the panel frame 10 in the wall thickness direction so as to extend in the panel width direction (wall width direction). This configuration reduces the amount of surface material required at the construction site, as the upper side member 23 is already fixed to the panel frame 10, thereby reducing the space required for storing the surface material. Furthermore, since a surface material (lower side surface material 29) can be fixed to the lower side of the upper end side surface material 23 at the construction site, wiring etc. can be easily performed inside the panel frame body 10.

[0011] Furthermore, as will be described later, if the upper end side surface material 23 is made of a non-combustible board, the upper end side surface material 23 can function as a fire stop material. Furthermore, as will be described later, if the upper end side surface material 23 is configured so that its lower end is at a height below the ceiling surface (the lower surface of the ceiling material 7 (see Figure 4(a))), there is no restriction on the order of installation of the lower side surface material 29 fixed to the lower side of the upper end side surface material 23 and the ceiling material 7. This upper end side surface member 23 is provided with a receiving recess 24 that receives the end of the joint object to be joined to one surface of the cross member 11 in the wall thickness direction. With this configuration, there is no need to cut out the surface material fixed to one surface of the cross member 11 in the wall thickness direction at the construction site in accordance with the joint object, improving workability. Furthermore, by providing the panel frame 10 with the configuration described above and the upper end side surface member 23, on-site work can be reduced, thereby reducing variation in construction quality among workers.

[0012] In this embodiment, as shown in Fig. 1, the wall panel 1 is installed to form an exterior wall that separates the indoors and outdoors of a building such as a residence. This wall panel 1 is installed to form the exterior wall of each floor of the building. The illustration shows a portion of the first floor of the building, with the wall panel 1 installed on the rising portion of the foundation 2 via a base 3. The foundation 2 is a reinforced concrete foundation constructed on the ground. This foundation 2 may be, for example, a so-called strip foundation in which a long horizontal base 3 is installed on the upper side and the rising portion is provided along the perimeter of the building and the main partition wall portion, but the example shown in the figure is a so-called mat foundation in which the lower end of the rising portion is integrated with the base plate. A plurality of anchor bolts are embedded in this foundation 2 at intervals along the longitudinal direction of the base 3 so that they protrude upward.

[0013] The base 3 is made of wood, such as cross-laminated timber (CLT), laminated lumber, or laminated veneer lumber (LVL), or solid wood, and has a generally rectangular pillar shape. The base 3 is provided with a plurality of insertion holes at intervals along its length, through which column connector fittings 4, which are attached to anchor bolts and joined to the lower ends of the columns 12 of the wall panel 1 described below, are inserted. Each base 3 may be joined to adjacent bases 3 with appropriate connector fittings. An appropriate foundation packing may be disposed between the underside of the base 3 and the upper end of the foundation 2. The foundation 2 need not necessarily be configured to extend along the entire length of the lower side of the base 3, but may have cutouts in appropriate locations for ventilation, piping, inspection, etc. Joists that are supported by floor beams and the like are joined to the base 3. The illustration shows an example in which floor subfloor plywood 5 that forms the floor substructure is installed on the base 3 and joists. As shown in Figure 5, the floor subfloor plywood 5 has a notched recess that receives the lower end of the pillar material 12.

[0014] 1 and 5 illustrate a first wall panel 1A and a second wall panel 1B joined in the wall width direction, and a third wall panel 1C joined perpendicularly to the second wall panel 1B, as the wall panel 1. The common configuration of the first wall panel 1A, the second wall panel 1B, and the third wall panel 1C will be described as the wall panel 1. The height dimension of the wall panel 1 is determined according to the ceiling height plus the height of the underfloor space (ceiling space) formed between the wall panel 1 and the upper floor. The height dimension of the wall panel 1 may be, for example, approximately 2700 mm to 3600 mm. The wall width dimension of the wall panel 1 is set appropriately depending on the ease of handling, the layout of the building, etc. The wall width dimension of the wall panel 1 may be, for example, approximately 1800 mm to 6000 mm. The wall width dimension of the wall panel 1 may be set to an integer multiple of the width dimension (standard width) of the standard-sized face materials (exterior wall side material 21 and lower side material 29) fixed to both sides in the wall thickness direction.

[0015] The panel frame 10 constitutes the core material of the wall panel 1, and constitutes the structural material and wall foundation of the building. As shown in Figure 3, the horizontal members 11 of the panel frame 10 are elongated in the wall width direction and form beams or girders as structural members. A plurality of column members 12, which are elongated in the vertical direction and form structural columns, are joined to the horizontal members 11 at intervals in the longitudinal direction. A first column member 12A, which constitutes a column member 12, is joined to a first end portion on one longitudinal side of the cross member 11, with its upper end surface abutting against the end face of the first end portion. The first column member 12A is joined to the first end portion of the cross member 11 in a longitudinal direction so that its upper end surface is flush with the top surface of the cross member 11. As shown in FIG. 5 , a beam connector 22 is attached to one or both of one side in the wall width direction (the outer side of the wall panel 1 in the wall width direction) and one side in the wall thickness direction (the interior side) of the upper end portion of the first column member 12A. The beam connector 22 connects the cross member 11 of another wall panel 1 adjacent to one or both of the outer side in the wall width direction and the interior side of the wall panel 1, or a beam (second beam 35) (described later) that constitutes the joint target, to the wall panel 1. The illustrated example shows an example in which the beam connector 22 is provided on one side in the wall thickness direction of the first column member 12A of the first wall panel 1A. Also shown is an example in which beam connectors 22, 22 are provided on the outer side of the wall width direction and one side of the wall thickness direction of the first pillar material 12A of the second wall panel 1B. Also shown is an example in which a beam connector 22 is provided on one side of the wall thickness direction of the first pillar material 12A of the third wall panel 1C.

[0016] The beam connector 22 includes a fixed piece that is positioned along the fixed surface of the first column 12A and fixed to the first column 12A with appropriate fasteners or fixtures, such as screws, and a pair of engaging pieces that protrude from both edges of the fixed piece. The pair of engaging pieces are spaced apart in the thickness direction of the objects to be connected (the beam 11 or the second beam 35) and are flat plates with the same thickness direction. As shown in FIG. 4(b), the upper ends of the pair of engaging pieces of the beam connector 22 are provided with recesses 22a that penetrate the thickness direction and open upward. Instead of such recesses 22a, insertion holes may be provided. One or more insertion holes 22b that penetrate the thickness direction are provided at vertically intermediate positions of the pair of engaging pieces of the beam connector 22. The example shown in FIG. 4(b) illustrates an example in which multiple insertion holes 22b are provided at intervals in the vertical direction of the pair of engaging pieces. The number of insertion holes 22b and the vertical dimensions of the beam joint fitting 22 are set to an appropriate number and dimensions depending on the vertical dimensions of the object to be joined.

[0017] As shown in FIGS. 3 and 5, a second end portion of the cross member 11 on the other longitudinal side is provided with an engagement groove 11a for receiving a beam connector 22 provided on another adjacent wall panel 1. The engagement groove 11a opens outward in the longitudinal direction of the cross member 11 and penetrates vertically. Two receiving grooves for receiving each engagement piece may be provided on the groove bottom side of the opening side that receives the base end of the beam connector 22 in the engagement groove 11a. The second end portion of the cross member 11 is provided with a plurality of insertion holes 11b spaced apart vertically, through which pins (drift pins) 8 (see also FIG. 4(a)) are inserted into the recesses 22a and insertion holes 22b of the beam connector 22 received in the engagement groove 11a. Each insertion hole 11b is provided to penetrate the cross member 11 in the thickness direction and to communicate with the engagement groove 11a. A reinforcing metal fitting having a through hole aligned with the insertion hole 11b may be provided along the inner groove surface of the engagement groove 11a.

[0018] As shown in Fig. 5, a beam joint fitting 22 similar to the above is provided at a longitudinal midpoint on one side (indoor side) of the cross member 11 in the wall thickness direction to join the objects to be joined. The illustrated example shows an example in which a plurality of beam joint fittings 22 are provided at intervals in the longitudinal direction of the cross member 11. The beam joint fittings 22 provided on the cross member 11 and the first column member 12A may be fixed to the wall panel 1 in advance at a factory or the like, or may be fixed at a construction site or the like after shipping from the factory. In Fig. 1, the first wall panel 1A shows an example in which two first beams 34, 34 with relatively large vertical dimensions are joined to a second beam 35 with a vertical dimension smaller than that of the first beam 34 via beam joint fittings 22, 22, 22. The second wall panel 1B shows an example in which the second beam 35 is joined to a third beam 36 with a vertical dimension smaller than that of the second beam 35 and constituting the upper end of the partition wall 9, and a fourth beam 37 with a vertical dimension smaller than that of the third beam 36 are joined to the second beam 35 via beam joint fittings 22, 22, 22. The third wall panel 1C shows an example in which a fifth beam 38 with a vertical dimension approximately the same as that of the third beam 36 is joined to the fifth beam 38 via beam joint fittings 22. The figure also shows an example in which one end of a fifth beam 38, one end of which is joined to the third wall panel 1C, is joined to a longitudinally intermediate portion of the third beam 36 that constitutes the upper end of the partition wall 9. The figure also shows an example in which the other end of a fourth beam 37, one end of which is joined to the second wall panel 1B, is joined to a longitudinally intermediate portion of the fifth beam 38. The figure also shows an example in which longitudinally intermediate portions of adjacent beams 34, 35, 36 that are joined to the first wall panel 1A and the second wall panel 1B and arranged in parallel as described above are joined together by a sixth beam 39 whose vertical dimension is approximately the same as that of the fourth beam 37.

[0019] As described above, beam joining fittings 22 similar to those described above are provided at the joints of the beams (first beam 34, second beam 35, third beam 36 and fifth beam 38) to which other beams (fourth beam 37 and sixth beam 39) are joined at intermediate longitudinal positions. Furthermore, the longitudinal ends of the first beam 34, second beam 35, third beam 36, fourth beam 37, fifth beam 38, and sixth beam 39 are provided with the same engagement grooves as above and insertion holes 34a (see FIG. 6(a)) through which the pins 8 are inserted. The pins 8 that are hooked into the recesses 22a of the beam joint fittings 22 may be inserted in advance into the insertion holes 34a at the top of the first beam 34, second beam 35, third beam 36, fourth beam 37, fifth beam 38, and sixth beam 39. The first beam 34, second beam 35, third beam 36, fourth beam 37, fifth beam 38, and sixth beam 39 are arranged so that their respective upper surfaces are flush with the upper end surfaces of the panel frames 10 of the respective wall panels 1, and form the ceiling substructure and the floor substructure (floor beams) of the upper floor. The first beam 34, second beam 35, third beam 36, fourth beam 37, fifth beam 38, and sixth beam 39 may be made of wood-based materials similar to those described above, or may be made of solid wood. The objects to which each wall panel 1 is joined are not limited to the above configurations, and various other configurations may also be used.

[0020] As shown in FIG. 3 , second pillar members 12B, which constitute pillar members 12, are joined to a longitudinally intermediate portion of the underside of the cross member 11, with their upper end surfaces abutting the underside. In the illustrated example, multiple second pillar members 12B are spaced apart along the longitudinal direction of the cross member 11. The first pillar members 12A and the second pillar members 12B may be arranged at a pitch (spacing) that corresponds to the width of the standard-sized face members (exterior wall side member 21 and lower side member 29). In other words, the dimension from the center of one of the adjacent pillar members 12 (first pillar member 12A and second pillar member 12B) in the wall width direction to the center of the other may be approximately the same as the width of the standard-sized face members (exterior wall side member 21 and lower side member 29). The pitch between these pillar members 12 (first pillar members 12A and second pillar members 12B) may be, for example, approximately 900 mm to 1200 mm. The lower ends of these columns 12 (first column 12A and second column 12B) are provided with insertion holes that open downward, into which column joint fittings 4 are inserted. The lower ends of these columns 12 (first column 12A and second column 12B) may also be provided with insertion holes that align with insertion holes that penetrate horizontally through the column joint fittings 4 and through which pins (drift pins) are inserted. Column joint fittings 4 similar to those described above may be embedded in the upper ends of the first column 12A and the top surfaces of the cross members 11 directly above the second column 12B, to be joined to the lower ends of the columns 12 of the wall panels 1 on the upper floor. The beam joint fittings 22 provided at the longitudinal midpoints of the cross members 11 are provided so as to be located above the respective second pillar members 12B, as shown in FIG. 2(a).

[0021] As shown in FIG. 3 , the panel frame 10 includes a plurality of vertical beam members 13, each with its upper end joined to the underside of the second end and a longitudinally intermediate portion of the horizontal beam member 11. The vertical beam members 13 have a smaller dimension along the wall width direction than the column members 12, forming a wall base. The vertical beam members 13 joined to the underside of the second end portions of the horizontal beam members 11 are arranged so that the surfaces facing outward in the wall width direction are flush with the end faces of the second end portions of the horizontal beam members 11. The vertical beam members 13 arranged along the longitudinal intermediate portion of the horizontal beam members 11 are arranged so as to be positioned approximately in the center of the wall width direction between the column members 12 (the first column member 12A and the second column member 12B or the second column members 12B, 12B) adjacent to each other in the wall width direction. Another vertical beam member 13 is also provided at approximately the center of the wall width direction between the vertical beam member 13 at the second end and the adjacent second column member 12B. The upper end of a vertical beam member 13 is also joined to the underside of the first end of the horizontal member 11, the vertical beam member 13 being provided along the inner surface of the first pillar member 12A in the wall width direction.

[0022] As shown in Fig. 5, an opening 19 is provided in the panel frame 10 of one of the multiple wall panels 1. In the illustrated example, openings 19, 19 constituting a window portion are provided in the first wall panel 1A and the second wall panel 1B, and no opening 19 is provided in the third wall panel 1C, but this is not a limited example. In addition, in the illustrated example, the dimension along the vertical direction of the opening 19 in the first wall panel 1A is larger than the dimension along the vertical direction of the opening 19 in the second wall panel 1B, but this is not a limited example. The illustrated example shows an example in which an opening 19 is provided in a vertically intermediate position between adjacent second pillar members 12B, 12B in the width direction of the wall, forming a waist-high window section. This opening 19 is defined by a window base 18 that surrounds it on all four sides, as shown in Figure 3. The illustrated example shows a window base 18 that includes upper and lower horizontal rail members that are provided to span between the second pillar members 12B, 12B and define the top and bottom of the opening 19, and vertical rail members on both sides that are provided to span between the upper and lower horizontal rail members and define both sides of the opening 19 in the width direction of the opening.

[0023] A vertical sash 16 is provided so as to span between the upper horizontal sash (lintel) of the window sill 18 and the horizontal member 11. A horizontal sash 17 is provided so as to span between the second pillars 12B, 12B and between the lower horizontal sash (window sill) of the window sill 18 and the lower pillar 14. Vertical sashes 16, 16 are provided on both the top and bottom of this horizontal sash 17 so as to span between the lower horizontal sash and the lower pillar 14 of the window sill 18, respectively. The vertical sashes 16, 16, 16 provided on both the top and bottom of the window sill 18 are provided so as to be located approximately in the center in the wall width direction between the pillars 12 (second pillars 12B, 12B) adjacent in the wall width direction, similar to the vertical sash 13 described above. The window base 18 that defines the opening 19 is not limited to the configuration described above, and may have various other configurations. The window portion defined by the opening 19 is not limited to a waist-high window, but may also be a French window, a window portion provided near the floor (ground window), or a window portion provided near the ceiling (high window). Furthermore, the opening 19 may be configured to have a door body that opens and closes the entrance instead of a window portion. The opening 19 is not limited to a configuration that is provided so as to fit between adjacent second pillar members 12B, 12B in the wall width direction, but may also be configured so as to cross one or more second pillar members 12B, or may have various other configurations.

[0024] As shown in FIG. 3 , the lower rails 14 are arranged to bridge adjacent columns 12 (the first column 12A and the second column 12B or the second column 12B, 12B) in the wall width direction and between the vertical rail 13 at the second end and the adjacent second column 12B. The lower rails 14 are arranged to be at the same height as each other. The lower ends of the vertical rails 13 (and the vertical rail 16 below the opening 19) are joined to the lower rail 14 with their lower end surfaces abutting the upper surface of the lower rail 14. The lower ends of the first column 12A and the second column 12B are arranged so that they protrude downward beyond the underside of the lower rail 14. The protrusion distance of the lower ends of the first column 12A and the second column 12B from the underside of the lower rail 14 is approximately the same as the thickness of the underfloor plywood 5. The first pillar 12A and the second pillar 12B are installed with their lower end surfaces abutting against the base 3. The lower rail 14 is installed with its lower surface abutting against the floor plywood 5. The panel frame 10 has upper horizontal beams 15 that are provided so as to span between adjacent vertical members (first pillar member 12A, second pillar member 12B, and vertical beam members 13, 16) at intervals below the horizontal members 11. The upper horizontal beams 15 are provided so as to be positioned at the same height as each other.

[0025] The horizontal members 11, first pillar members 12A, second pillar members 12B, vertical members 13, 16, lower member 14, upper horizontal member 15, horizontal member 17, and window siding 18 that make up the panel frame 10 have the same dimensions along the wall thickness direction so that their respective surfaces in the wall thickness direction are flush with one another. The dimensions of the horizontal members 11, first pillar members 12A, second pillar members 12B, vertical members 13, 16, lower member 14, upper horizontal member 15, horizontal member 17, and window siding 18 in the longitudinal direction and in the direction perpendicular to the wall thickness direction may be set to appropriate dimensions from the viewpoint of strength, etc. The horizontal member 11, the first pillar member 12A, the second pillar member 12B, the vertical members 13, 16, the lower member 14, the upper horizontal member 15, the horizontal member 17, and the window base 18 are made of wood, either from wood-based materials similar to those described above or from solid wood. The panel frame 10 is not limited to the above-described configuration, and may have various other configurations.

[0026] As shown in FIG. 4( a), the hollow spaces enclosed by the components constituting the panel frame 10 (horizontal members 11, first column members 12A, second column members 12B, vertical members 13, 16, bottom member 14, upper horizontal member 15, horizontal member 17, and window siding 18) are filled with insulating material 20. Such insulating material 20 may be a foam-based insulating material primarily composed of synthetic resin, or a fiber-based insulating material containing mineral fibers such as glass wool or rock wool. The insulating material 20 may be pre-filled in at least those hollow spaces covered by the upper side panel member 23 (described below), or may be pre-filled in all hollow spaces. In the illustrated example, the insulating material 20 has a dimension along the wall thickness direction that is approximately the same as the dimension along the same direction of the panel frame 10. However, the present invention is not limited to this example, and the insulating material 20 may be configured to allow for the installation of cables, plug connectors, switches (control panels), and the like indoors. Furthermore, a power outlet box constituting a plug connector, a switch box constituting a switch, etc. may be fixed to the panel frame 10 in advance.

[0027] As shown in FIGS. 2 and 4 , an exterior wall side surface material 21 may be pre-fixed to the outdoor side of the panel frame body 10, which is the other side in the panel thickness direction. This exterior wall side surface material 21 has an opening corresponding to the opening 19. This exterior wall side surface material 21 may be a wood-based board such as plywood or particle board. The illustrated example shows an example in which multiple exterior wall side surface materials 21 are fixed to the panel frame body 10 in the wall width direction. These exterior wall side surface materials 21 are fixed to the panel frame body 10 with fasteners such as screws. In the illustrated example, the exterior wall side surface material 21 is fixed so that the upper end of the panel frame body 10 is exposed. That is, the exterior wall side surface material 21 is fixed to the panel frame body 10 so that its upper end surface is located below the upper end surface of the panel frame body 10. The exterior wall side surface material 21 is fixed to the panel frame body 10 so that its lower end protrudes downward below the lower end surface of the panel frame body 10. The protruding portion at the lower end of the exterior wall side surface material 21 is arranged so as to fit along the outdoor side surface of the structural material below (the outdoor side surface of the base 3 in FIG. 4(a)).

[0028] As shown in FIG. 2 , the adjacent side end of the exterior wall side material 21 of a first wall panel 1A, which is one of the wall panels 1 adjacent to each other in the wall width direction, is provided with a protruding portion that protrudes in the wall width direction beyond the panel frame 10 of the first wall panel 1A. The adjacent side end of the exterior wall side material 21 of a second wall panel 1B, which is the other of the adjacent wall panels 1, is located more inward in the wall width direction than the adjacent end face of the panel frame 10 of the second wall panel 1B so as to be able to receive the protruding portion. In other words, the protruding portion of the exterior wall side material 21 of the first wall panel 1A is overlapped and fixed to the exposed portion of the panel frame 10 of the second wall panel 1B. The exterior wall side material 21 provided on the outdoor side of the panel frame 10 is not limited to this configuration and may have various other configurations. Furthermore, the exterior wall side material 21 of the adjacent side ends of wall panels 1, 1 that are joined orthogonally to form an exterior corner or an interior corner may have an appropriate configuration depending on the exterior corner or the interior corner. In addition to the exterior wall side material 21, some or all of the moisture-permeable waterproof sheet, furring strips, and exterior wall material may be provided on the outdoor side of the panel frame 10. Furthermore, if a window sash has been fitted into the opening 19 in advance, a waterproof base treatment or the like may be applied around the periphery of the opening 19.

[0029] The upper side surface material 23 is shaped like a strip of wood that is long in the wall width direction. This upper side surface material 23 is pre-fixed to the panel frame 10 with appropriate fasteners. The upper portion of this upper side surface material 23 may be fixed to the cross member 11 with fasteners, and its lower end may be fixed to the upper cross rail 15 with other fasteners. This upper side surface material 23 may be a non-combustible board such as gypsum board or calcium silicate board. The vertical dimensions of this upper side surface material 23 may be appropriately dimensioned so that it functions as a fire stop material. The illustrated example shows an example in which the upper side surface material 23 is fixed to the upper end of the panel frame 10 so that the upper portion of the cross member 11 is exposed. As shown in FIG. 2( a), the adjacent side end of the upper side member 23 of a first wall panel 1A, which is one of the wall panels 1 adjacent to each other in the wall width direction, is provided with a protruding portion 25 that protrudes in the wall width direction beyond the panel frame 10 of the first wall panel 1A. The adjacent side end 26 of the upper side member 23 of a second wall panel 1B, which is the other of the adjacent wall panels 1, is positioned more inward in the wall width direction than the adjacent end face of the panel frame 10 of the second wall panel 1B so as to be able to receive the protruding portion 25. With this configuration, the protruding portion 25 of the upper side member 23 of the first wall panel 1A can be fixed to the panel frame 10 of the second wall panel 1B. This allows the joint between the upper side members 23, 23 adjacent in the wall width direction to be positioned differently from the joint between the panel frames 10, 10 adjacent in the wall width direction, making it less likely that a step or the like will occur at the joint between the upper side members 23, 23 adjacent in the wall width direction.

[0030] The protrusion dimension of the protrusion 25 from the panel frame 10 may be an appropriate dimension from the viewpoint of securing the adjacent wall panel (second wall panel 1B) to the panel frame 10 and preventing damage. The protrusion dimension of this protrusion 25 from the panel frame 10 may be, for example, 20 mm or more, or may be equal to or less than the dimension along the wall width direction of the first pillar member 12A, and preferably equal to or less than half the dimension along the wall width direction of the first pillar member 12A. In the illustrated example, the protrusion 25 of the upper side member 23 of the first wall panel 1A defines the bottom of the receiving recess 24 that receives the joining object (the second beam 35 in FIG. 1 ) to be joined to the upper end of the first pillar member 12A of the second wall panel 1B. The adjacent side end 26 of the upper side member 23 of the second wall panel 1B defines the bottom of the receiving recess 24 that receives the joining object to be joined to the upper end of the first pillar member 12A of the second wall panel 1B. In other words, the protrusion 25 and the adjacent side end 26, which are abutted in the wall width direction, define the bottom of the receiving recess 24 that receives the joining object. Alternatively, only the protrusion 25 may define the bottom of the receiving recess 24. The receiving recess 24 penetrates in the wall thickness direction and opens upward. The dimensions of the receiving recess 24 along the wall width direction and along the vertical direction are set to appropriate dimensions depending on the object to be joined.

[0031] The receiving recess 24 for receiving the objects to be joined (the first beam 34 and the second beam 35 in FIG. 1) to the longitudinal intermediate portion of the cross member 11 is provided so as to penetrate the upper side surface member 23 in the wall thickness direction and open upward, as described above. The receiving recess 24 is provided at a position corresponding to the beam joint fitting 22 provided at the longitudinal intermediate portion of the cross member 11. As described above, the dimensions of this receiving recess 24 along the wall width direction and along the vertical direction are set appropriate depending on the objects to be joined. Note that the receiving recess 24 does not have to be provided in the longitudinal intermediate portion of the cross member 11 where the objects to be joined (the fourth beam 37 and the fifth beam 38 in FIG. 1) with relatively small vertical dimensions are to be joined (see also FIG. 5). Furthermore, when a partition wall 9 (see FIG. 1) is joined perpendicularly to a middle portion of the wall panel 1 in the wall width direction, a notch 24A may be provided in the upper side surface member 23 as a receiving recess to accommodate the partition wall 9 (see FIG. 5). That is, a middle portion of the upper side surface member 23 in the longitudinal direction may be provided with a notch 24A to accommodate the partition wall 9, dividing the middle portion in the wall width direction. The illustrated example shows an example in which a notch 24A is provided in a middle portion of the upper side surface member 23 in the longitudinal direction of the second wall panel 1B. This notch 24A is provided so as to leave the upper side surface member 23 missing across the entire vertical direction. The dimension of this notch 24A along the wall width direction corresponds to the wall thickness of the partition wall 9.

[0032] In addition, the illustrated example shows an example in which the upper end side surface material 23 of the wall panel 1 is made up of multiple face materials in the wall width direction, and the adjacent side edges of these face materials define the bottom portion of the receiving recess 24. In other words, the adjacent side edges of the multiple face materials that make up the upper end side surface material 23 are provided with protrusions that define the bottom portion of the receiving recess 24. The dimension along the wall width direction of each panel member constituting the upper end side surface member 23 may be the same as the width dimension of the standard dimension panel members (exterior wall side surface member 21 and lower side surface member 29). The thickness dimension of the upper end side surface member 23 may be approximately 9 mm to 25 mm, or may be 12 mm or more. Instead of the above-described embodiment, a configuration may be adopted in which a protrusion that defines the bottom portion of receiving recess 24 is provided on only one adjacent side end portion of the panel materials that are adjacent in the wall width direction and that make up upper end side surface material 23. Alternatively, a configuration may be adopted in which a panel material that defines the bottom portion of receiving recess 24 is provided between the adjacent side ends of adjacent panel materials that are spaced apart in the wall width direction and that make up upper end side surface material 23.

[0033] When another wall panel 1 is joined perpendicularly to a first pillar member 12A of a wall panel 1 so as to form an interior corner with the wall panel 1 on the indoor side, the pillar-side end 26A of the upper side surface member 23 may be positioned inward in the wall width direction so as not to overlap the first pillar member 12A (see Figures 2(a) and 5). In this way, the pillar-side end 26A of the upper side surface member 23 may be positioned inward in the wall width direction so as not to overlap the first pillar member 12A, and the missing portion may be understood as a receiving recess. The illustrated example shows an example in which the pillar-side end 26A of the upper side surface members 23 of the first wall panel 1A and the third wall panel 1C are positioned inward in the wall width direction so as not to overlap the first pillar member 12A. The receiving recess 24 provided in the upper end side surface member 23 and the cutout portion 24A that forms the receiving recess are not limited to the configurations described above, and can be modified appropriately depending on the object to be joined.

[0034] As shown in Fig. 4(a), the upper end side surface material 23 is provided so that its lower end is at or below the height of the ceiling surface (the lower surface of the ceiling material 7). In the illustrated example, the lower end of the upper end side surface material 23 and the ceiling surface (the lower surface of the ceiling material 7) are at approximately the same height, but this is not a limitation. A ceiling siding 30, which constitutes a long ceiling substructure extending in the width direction of the wall, is fixed along the upper side surface member 23. This configuration eliminates the need to fix the substructure of the ceiling material 7 along the wall at the construction site, improving workability. The ceiling siding 30 may be pre-fixed to the upper horizontal rail 15 via the upper side surface member 23 using fasteners. In the illustrated example, the ceiling siding 30 has a fixing piece that abuts the upper side surface member 23 and two side pieces that protrude toward the interior from both the upper and lower edges of the fixing piece, forming a roughly C-shape when viewed longitudinally. In other words, the ceiling siding 30 has a channel-shaped opening that faces horizontally. Alternatively, the ceiling siding 30 may be a wooden rectangular pillar.

[0035] In order to avoid interference with the edge 30 of another wall panel 1 to which it is joined perpendicularly, the edge 30 of this wall panel 1 may be provided so that its longitudinal end is positioned more inward in the wall width direction than the end face of the panel frame 10. When the partition wall 9 is joined as described above, the edge 30 may be divided midway in the wall width direction, as shown in Figure 5. As shown in FIG. 4(a), the ceiling substructure includes siding members 31 arranged at multiple locations parallel to the siding members 30 with a gap in one direction so that the underside is substantially flush with the underside of the siding members 30. The ceiling substructure also includes siding members 32, 32 arranged at multiple locations perpendicular to the siding members 31 with a gap in the other direction, supporting the longitudinal intermediate portions of the siding members 31. The illustrated example shows an example in which the siding members 32, 32 are suspended from first beams 34, 34 joined to two intermediate portions of the first wall panel 1A in the wall width direction via hanging members 33, 33. The longitudinal ends of the siding members 31 may be supported by other siding members 30 arranged perpendicular to the siding members 31 or by siding members 30 on both sides of the partition wall 9 in the wall thickness direction. In other words, the siding members 30 may function as siding hangers. The ceiling substrate that holds the ceiling material 7 is not limited to a steel substrate as shown in the figure, but may be a wooden substrate, and various other modifications are possible. Also, instead of the above-mentioned girders 30 being pre-installed on the wall panel 1, they may be fixed at the construction site.

[0036] As shown in Figure 5, an opening perimeter panel 27 is fixed to one surface in the wall thickness direction of the panel frame 10 on which the opening 19 is provided, so as to surround the opening 19. With this configuration, it is not necessary to fix a panel material by cutting or the like so as to surround the opening 19 at the construction site, thereby improving workability. The opening perimeter panel 27 and the upper end side surface member 23 are provided adjacent to each other in the panel height direction. With this configuration, it is not necessary to fix a panel material between the opening perimeter panel 27 and the upper end side surface member 23 at the construction site, thereby improving workability. The opening surrounding panel 27 has its upper end face abutted against the lower end face of the upper side panel 23, and is fixed in advance to the panel frame 10 with appropriate fasteners. This opening surrounding panel 27 may have its upper end fixed to the upper horizontal rail 15, its lower end fixed to the horizontal rail 17, and both widthwise ends fixed to the pillars 12 (second pillars 12B, 12B). In addition, the peripheral edge of this opening surrounding panel 27 on the opening 19 side may be fixed to the window base 18. This opening-periphery panel 27 may be a non-combustible board similar to the upper end side panel 23 described above. The thickness of this opening-periphery panel 27 is the same as that of the upper end side panel 23 described above. The height of this opening-periphery panel 27 may be an appropriate dimension so that both upper and lower ends can be fixed to the fixing objects described above. The width of this opening-periphery panel 27 may be an appropriate dimension so that both widthwise ends can be fixed to the fixing objects described above.

[0037] As shown in FIGS. 2(a) and 3 , the opening-periphery panel 27 is composed of two panels divided at the center of the opening 19 in the width direction and butted together in the wall width direction. The two panels constituting the opening-periphery panel 27 are generally C-shaped (U-shaped) when viewed in the wall thickness direction, opening toward each other in the wall width direction. This configuration reduces misalignment, gaps, and cracks in the wallpaper attached to the surface compared to a corner around the opening 19 formed by butting multiple panels together. The butting ends of these panels may be fixed to the vertical crosspiece 16. The opening-periphery panel 27 is not limited to this generally C-shaped configuration, opening toward each other in the width direction, but may also be generally C-shaped opening toward each other in the vertical direction, or may have various other configurations. Furthermore, depending on the opening width, opening height, etc. of opening 19, opening-surrounding panel 27 may be configured by providing a rectangular flat panel between roughly C-shaped panel members. Furthermore, instead of configuring opening-surrounding panel 27 from a plurality of panel members in this manner, a configuration may be adopted in which a single opening-surrounding panel 27 having an opening corresponding to opening 19 is provided.

[0038] 1, a lower end side surface member 28 is fixed to the lower side of this opening surrounding surface member 27. At the construction site, this lower end side surface member 28 is fixed to the panel frame 10 with an appropriate fastener, with its upper end surface abutting against the lower end surface of the opening surrounding surface member 27. This lower end side surface member 28 may have its upper end fixed to the horizontal rail member 17, its lower end fixed to the lower rail member 14, and both widthwise ends fixed to the pillar members 12 (second pillar members 12B, 12B). This lower end side surface material 28 may be a non-combustible board similar to the above-described upper end side surface material 23. The thickness dimension of this lower end side surface material 28 is the same as that of the above-described upper end side surface material 23. The height dimension of this lower end side surface material 28 may be an appropriate dimension so that both upper and lower end portions can be fixed to the above-described fixing objects. The width dimension of this lower end side surface material 28 may be an appropriate dimension so that both widthwise end portions can be fixed to the above-described fixing objects. Instead of the mode in which the lower end side surface member 28 is fixed to the lower side of the opening periphery surface member 27 at the construction site, the entire lower side of the opening 19 may be formed by the opening periphery surface member 27.

[0039] As shown in Figure 4(a), the mounting height of the panel material below the upper side surface material 23 of the panel frame 10 corresponds to the height of the lower side surface material 29, which is a standard-sized surface material (standard-length board). This configuration allows the lower side surface material 29, which has a standard height, to be fixed below the upper side surface material 23, reducing cutting work and the like at the construction site. This reduces the amount of waste material generated from the surface material. This lower side surface material 29 may be a non-combustible board similar to the above-mentioned upper side surface material 23. The height dimension (standard height) of this lower side surface material 29 may be approximately 1800 mm to 2500 mm. The width dimension (standard width) of this lower side surface material 29 may be approximately 900 mm to 1200 mm. The thickness dimension of this lower side surface material 29 is the same as that of the above-mentioned upper side surface material 23. This lower side member 29 may be fixed to the panel frame 10 at the construction site using appropriate fasteners. The upper end of this lower side member 29 may be fixed to the upper horizontal rail 15, its lower end to the lower rail 14, and both widthwise ends to the columns 12 or vertical rails 13. While the illustrated example shows an example in which the lower end surface of the lower side member 29 abuts or is close to the upper surface of the floor finishing material 6 provided on the underfloor plywood 5, it may also abut or be close to the upper surface of the underfloor plywood 5. Where the wall panels 1, 1 are joined perpendicularly, this lower side member 29 may be cut to an appropriate width rather than a fixed width. Furthermore, similar upper side member 23 and lower side member 29 may be fixed to both sides of the partition wall 9 in the wall thickness direction.

[0040] As shown in FIGS. 4(b) and 5, the wall panels 1 configured as described above may be installed sequentially after the floor underlayment plywood 5 constituting the first floor floor underlayment has been installed. For example, the first wall panel 1A is erected by joining the lower ends of each column 12 to the column joint fittings 4 with pins. Then, the beam joint fittings 22 provided on the first column 12A of the second wall panel 1B are engaged with the engagement grooves 11a of the cross members 11 of the first wall panel 1A, and the lower ends of each column 12 of the second wall panel 1B are joined to the column joint fittings 4 with pins to erect the second wall panel 1B. Furthermore, the pins 8 are inserted through the insertion holes 11b of the cross members 11 of the first wall panel 1A and into the insertion holes 22b of the beam joint fittings 22 of the second wall panel 1B. Furthermore, the protrusions 25 of the upper side members 23 of the first wall panel 1A are fixed to the first column members 12A of the second wall panel 1B. In addition, the protruding portion of the exterior wall side surface material 21 of the first wall panel 1A is fixed to the first pillar material 12A of the second wall panel 1B. Similarly, the beam connectors 22 attached to the first column members 12A of the third wall panel 1C are engaged with the engagement grooves 11a of the cross members 11 of the second wall panel 1B, and the lower ends of the columns 12 of the third wall panel 1C are joined to the column connectors 4 with pins to erect the third wall panel 1C. Furthermore, the pins 8 are inserted through the insertion holes 11b of the cross members 11 of the second wall panel 1B and into the insertion holes 22b of the beam connectors 22 of the third wall panel 1C. Similarly, the wall panels 1 constituting the exterior walls of the first floor may be constructed.

[0041] Then, as shown in Figure 6(a), a beam (first beam 34 in Figure 6) to be joined is joined to each wall panel 1. At this time, the pin 8 inserted into the uppermost insertion hole 34a of each beam (first beam 34 in Figure 6) may be hooked into the recess 22a of the beam joint fitting 22 of each wall panel 1 and temporarily held therein, and then the pin 8 may be inserted into the insertion hole 22b of the beam joint fitting 22 via another insertion hole 34a. 6(b), a lower side surface material 29, a floor finishing material 6, a siding support 32 and a siding 31 that constitute the ceiling base, a ceiling material 7, etc. may be installed. Also, a partition wall 9 may be installed as appropriate. Although not shown in the drawings, the underfloor plywood 5 may be laid on the upper floor (second floor) side, the wall panels 1 on the upper floor may be laid, and then the roof and the like may be laid. The above construction procedure is merely an example, and other construction procedures may be used.

[0042] In the above example, the opening-periphery surface material 27 is provided in advance on the wall panel 1 provided with the opening 19, but the surface material around the opening 19 may be fixed at the construction site. In the above example, the exterior wall side surface material 21 is provided in advance on the wall panel 1, but the exterior wall side surface material 21 may be fixed at the construction site. The wall panel 1 may be configured to include at least a panel frame 10 having a cross member 11, a plurality of columns 12, and a lower cross member 14, and an upper end side surface material 23. In the above example, the wall panel 1 is configured to be installed as an exterior wall that separates indoors from outdoors, but it may also be configured to be installed as a partition wall that separates indoors. In this case, the above-mentioned upper side surface members 23, 23 may be provided at the upper ends of both sides of the panel frame 10 in the wall thickness direction. The configurations of the members and parts of the wall panel 1 according to this embodiment are not limited to the configurations described above, and various other modifications are possible.
