  According to the present invention, a wall panel is not manufactured on site using a wall frame, a structural plywood, a foam, and a gypsum board, but a wall panel is preliminarily at least a wall frame, an outer layer, an inner layer, and a wiring part. , And a moisture-proof layer to make a unit, which is then transported to the site and fixed.

As described above, according to the present invention, the wall panel is not manufactured on site, but is manufactured in advance in a factory or the like and then transported to the site. Therefore, the workability can be improved and the work period can be shortened, and the mechanical strength can be reduced. There is an effect that can be secured. Also, instead of attaching the wiring parts when the wall panel is fixed or after it is fixed, when the wall panel is manufactured in advance in a factory, etc., it can be inspected with the wiring part built in the wall frame, so it is engaged in work There is an effect that the wiring work can be made smooth, efficient, easy and the like without depending on the skill of the person who performs the work. In addition, the wiring code of the wiring part is not pulled out to the outside by inserting the wiring code of the wiring part into the moisture-proof layer, but it is not necessary to repair the insertion part of the moisture-proof layer because the wiring code of the wiring part is pulled out from the through hole at the top of the wall frame Excellent airtight structure can be obtained.

Also, when wall panels are manufactured in advance in factories, etc., a moisture-proof layer is interposed between the wall frame and the inner layer to ensure sufficient airtightness and to stabilize the quality. The airtightness can be maintained and stabilized without being influenced by the skill of the person who performs the work. In addition, since at least the lower part of the moisture-proof layer is exposed from between the wall frame and the inner layer and extends in a bent state in the outer layer direction, the lower end of the moisture-proof layer is overlapped with the lower surface of the lower part of the wall frame, thereby improving airtightness. Can do.
Also, the thread is not formed on the entire body of the first and second wood screw members, but the thread is formed only on the front part and the rear part of the body, and the thread is not formed on the other parts. Thus, it is possible to obtain a wood screw member that is strong against wind from the lateral direction, etc., and is superior in shear strength, strength, rigidity, and the like to a normal nail or screw.

Moreover, since the wall frame made of lumbar material is used, the drying property can be improved at low cost. Also, since the first partition material is installed between the upper and lower portions of the wall frame, and the second partition material is installed between both side portions of the wall frame, the wall frame can be configured to have a large size exceeding 2.33 m. Even if the wall panel is made to have a total height of 2.34 m or more and the ceiling is raised, excellent strength and rigidity can be obtained.
Moreover, if a plurality of spaces are formed by the first and second partition members and each of the partitioned spaces is filled with at least a heat insulating filler, the filler is prevented from being displaced or offset. It becomes possible.

Further, if a ventilation layer is provided on the outer layer of the wall panel, it is possible to prevent dew condensation due to high temperature and high humidity air or water vapor entering the filler. Further, if an outer wall material is provided in the ventilation layer, excellent appearance beauty and texture can be obtained.
Furthermore, if the silicone sealing material is filled in the gap between the structure and the lower lower surface of the inner layer of the wall panel, the airtightness can be improved.
Furthermore, because the wall panel is unitized, it is not possible to build a wall frame in the structure and fix the lower part with a nail, but the first wood screw member is inserted obliquely downward into the lower part of the outer layer. While fixing the wall panel and the structure, the wall panel and the structure are fixed to the lower part of the inner layer by inserting the second wood screw member obliquely downward, so that the wall panel is not manufactured in the field in advance. Even if a wall panel is manufactured at a factory and unitized, the wall panel can be firmly and easily fixed to the structure.

  The gypsum board 13 is formed in a vertically long rectangle having a thickness of 12.5 mm or more, and the lower part is shorter than the lower horizontal beam 4 of the wall frame 1. A gap 15 for sealing is formed in a rectangular cross section (see FIGS. 3 and 4). In the lower part of the gypsum board 13, tip holes, marks, and the like for the fasteners 40 are formed side by side as necessary. Moreover, the upper part of the gypsum board 13 is aligned with the upper horizontal rail 3 of the wall frame 1 as necessary, or is positioned lower than the upper horizontal rail 3.

  The wiring parts 16 are installed in the lower part of the pier 5 and exposed from the exposure opening 14 of the gypsum board 13, and the wiring cord connected to the outlet box 17 and exposed through the through hole 7 of the upper horizontal rail 3. 18. The outlet box 17 is covered with an outlet cover (not shown) that is screwed into the exposure port 14. Further, the wiring cord 18 is locked in the longitudinal direction of the pier 5 via a wiring fitting.

  Each glass wool 19 is made of, for example, an inorganic fiber material having excellent durability and water resistance. The glass wool 19 is filled in each of the plurality of spaces 8 of the wall frame 1 to cover the wiring parts 16 and exhibits a heat insulating function as a heat insulating material and a high airtight function.

  The moisture-proof and air-tight film 20 is formed in a rectangular shape using a film made of aluminum, OPP, PET, or the like having a thickness of 0.2 mm or more, for example, and the periphery of the upper, lower, and left and right sides is a wall frame 1. And the gypsum board 13 are exposed to the outside, and the exposed portion is sandwiched between the wall frame 1 and the structure 30 and between the wall frame 1 and another wall frame 1 adjacent to the wall frame 1 ( (See FIGS. 1 and 3).

  As shown in FIG. 3 and FIG. 4, the building structure 30 includes a foundation 31 placed and cured on a crushed crushed stone via a moisture-proof sheet. The pull is fixed by anchor bolts or the like, and a floor joist 33 for the first floor is assembled on the base 32 and the large pull. The floor joist 33 is provided with a heat insulating material 34 made of urethane foam or the like, and a structural plywood 35. And the flooring 36 which is the floor surface are sequentially laminated and laid.

  The lowermost portion 12 of the structural plywood 10 is fixed from the horizontal outer direction via a fastener 40 on the outer surface, which is an upright surface of the floor joist 33. In the gap 15 between the flooring 36 and the lower lower surface of the gypsum board 13, An airtight / waterproof sealant 37 made of modified silicone or the like is applied by a caulking gun.

As shown in FIGS. 4 to 6, the fastener 40 includes a plurality of nails 41 for fixing the lowermost part 12 of the structural plywood 10 and the outer surface of the floor joist 33, and the lower part of the structural plywood 10 obliquely from the outside. A dedicated first screw 42 that penetrates downward and fixes the lower horizontal rail 4 of the wall panel and the floor joist 33, and a lower horizontal rail of the wall panel that penetrates the lower part of the gypsum board 13 obliquely downward from the inside. 4 and a second screw 42A dedicated for fixing the floor joist 33.
The plurality of nails 41 are driven side by side in the left and right direction of the lowermost part of the structural plywood 10 and are arranged at intervals in the vertical direction.

  As shown in FIG. 5, the first and second screws 42 and 42 </ b> A have a barrel 43 formed to a diameter of φ4.2 mm using, for example, cast steel, forged steel, cast iron, carburized and hardened steel wire, or the like. A sharp screw thread 44 protrudes from the front portion and the rear portion of the body 43 including the sharp tip portion, and a head portion 45 having a substantially truncated cone shape and a hole is integrally formed at the end portion. The overall length is 12 cm and the size is 6 mm. These first and second screws 42 and 42A are screwed side by side in the left-right direction of the wall frame 1, and are arranged in a staggered manner so as not to interfere with each other (see FIG. 6).

  The inclination angle when the first and second screws 42 and 42A are screwed is not particularly limited, but is 45 ° to 85 °, preferably 60 ° to the horizontal plane from the viewpoint of improving workability. The range is 80 °. As such first and second screws 42 and 42A, a screw manufactured by Dandri Seisakusho (trade name SP-120: body diameter 4.2 mm, screw portion mountain diameter 6.0 mm, total length 120 mm, screw length 45 mm) is preferably used.

  In the above, when manufacturing a wall panel, first, the wall frame 1 is assembled using a pair of vertical bars 2, a pair of upper horizontal bars 3, a lower horizontal bar 4, a plurality of bars 5, and a horizontal bar 6 ( 7), a plurality of structural plywoods 10 are arranged in a horizontal row on the outer surface of the wall frame 1 through a nail and adhered (see FIG. 8), and the wall frame 1 with the opening 11 is turned upside down. .

  After the plurality of structural plywoods 10 are thus attached to the wall frame 1, the outlet box 17 and the wiring cord 18 of the wiring parts 16 are wired in the wall frame 1 (see FIG. 9), and the wiring cord 18 is connected to the pair of upper horizontal rails. 3 is pulled out from the through hole 7 and filled with glass wool 19 in the plurality of spaces 8 of the wall frame 1 to cover the wiring parts 16 (see FIG. 10).

  And the moisture-proof airtight film 20 is laminated | stacked on the inner surface of the wall frame 1, and several glass wool 19 is coat | covered (refer FIG. 11), the circumference | surroundings of the moisture-proof airtight film 20 are made to protrude from the circumference | surroundings of the wall frame 1, and the wall frame 1 A plurality of gypsum boards 13 are arranged in a row through nails and adhered to the inner surface of the board (see FIG. 12), and then the outlet box 17 of the wiring parts 16 is exposed from the exposure opening 14 of the gypsum board 13 to form a unit. Wall panels can be manufactured.

  Next, when a wall panel is joined and fixed to the structure 30 of the building, first, the transported wall panel is erected on the flooring 36 of the structure 30 already constructed, and the flooring 36 and the wall panel are placed between them. The bent lower part of the moisture-proof and airtight film 20 is bent and interposed (see FIGS. 3 and 4), and the lowermost part 12 of each structural plywood 10 is positioned on the outer surface of the floor joist 33 constituting the structure 30. The nail 41 is used for fixing.

  Next, a plurality of first screws 42 are inserted obliquely downward into the lower part of each structural plywood 10 to fix the lower cross rail 4 of the wall panel, the floor joists 33 of the structural body 30, and the structural plywood 35, A plurality of second screws 42 </ b> A are inserted obliquely downward at the bottom of each gypsum board 13 to fix the lower cross rail 4 of the wall panel, the floor joist 33 of the structure 30, and the structural plywood 35. A sealing material 37 for airtightness and waterproofing is applied to the gap 15 between the lower lower surface of 13 and the flooring 36 with a caulking gun to ensure the airtightness of the wall frame 1, the plasterboard 13 and the flooring 36 (see FIG. 3). .

  At this time, the plurality of first and second screws 42 and 42 </ b> A exhibit a strong frictional force and holding force by screwing the front screw thread 44 to the floor joist 33 of the structure 30, and the rear screw. The mountain 44 is screwed into the lower crosspiece 4 of the wall panel to exert a strong frictional force and holding force, and a central portion 46 not engraved with the screw thread 44 penetrates the lower horizontal crosspiece 4 of the wall panel (FIG. 4). reference).

  If a sheet-shaped windproof material 50, a ventilation layer 51, and a decorative fire-resistant outer wall material 52 are sequentially laminated on the outer surface of the plurality of structural plywoods 10 as the base material, the structure of the building A wall panel can be bonded and fixed to 30 (see FIG. 13). As the outer wall material 52, for example, a light wooden outer wall material, a metal outer wall material, an asbestos-based outer wall material, a lightweight cellular concrete, or the like is used.

  According to the above configuration, since the wall panel which is a main part is manufactured and stocked at the factory, it is not necessary to manufacture the wall panel at the site over time. Therefore, workability can be remarkably improved and the construction period can be shortened. Further, since it is not necessary to perforate the window holes 55 in the lower part and the side part of the plaster board 13 or to close each opened window hole 55 with plaster or the like, the mechanical strength of the wall panel itself is reduced. Suppression can be prevented.

  In addition, since a plurality of crosspieces 5 and crosspieces 6 are arranged and combined in the wall frame 1 to prevent the wall panel from being bent, it is excellent even when trying to increase the ceiling by setting the wall panel to an overall height of 2.34 m or more. The strength and rigidity can be effectively ensured. In addition, the wiring cord 18 of the wiring part 16 is not inserted through the moisture-proof airtight film 20 and pulled out to the outside, but the wiring cord 18 of the wiring part 16 is pulled out from the through-hole 7 of the upper side rail 3 to the outside. There is no need to repair the 20 insertion portions, and an excellent airtight structure can be obtained.

  In addition, the wall wool 1 is not simply filled with the glass wool 19, but the glass wool 19 is filled into each of the plurality of partitioned spaces 8, so that the workability can be improved by suppressing the positional displacement of the glass wool 19 and the like. become. Further, since the plurality of glass wools 19 are not simply covered with the moisture-proof and air-tight film 20, the moisture-proof and air-tight film 20 is laminated on the entire inner surface of the wall frame 1, and the periphery thereof is projected from the periphery of the wall frame 1. It is possible to improve heat insulation, improve the efficiency of energy used, prevent condensation and mold, and prevent the corrosion of buildings.

  Moreover, since the lowermost part 12 where the structural plywood 10 is extended is fixed to the outer surface of the floor joist 33, the structural plywood 10 can be easily temporarily fixed. Further, the lower portion of the moisture-proof and airtight film 20 is not simply aligned with the lower horizontal rail 4 of the wall panel, but the lower portion of the moisture-proof and airtight film 20 is inserted between the flooring 36 and the lower horizontal rail 4 of the wall panel so as to be dehumidified. It will be possible to significantly improve waterproofing and airtightness.

  In addition, because the wall panel is unitized, the wall frame 1 cannot be built on the floor surface of the structure 30 and the lower horizontal rail 4 cannot be fixed by the nail 41A. The wall 42 and the floor joist 33 are fixed by inserting the second screw 42 obliquely downward, and the wall panel and the floor joist 33 are fixed by inserting the second screw 42A obliquely downward to the lower part of the gypsum board 13. Instead of manufacturing the wall panel at the site, the wall panel can be firmly and easily fixed to the structure 30 even if the wall panel is manufactured in advance at the factory and unitized.

  Further, instead of using nails having a weak holding force or forming the screw threads 44 on the entire body 43 of the first and second screws 42 and 42A, only the front and rear portions of the cylinder 43 are threaded. 44 is formed in a protruding manner, and the strength is increased without forming the thread 44 in the central portion 46 of the body 43, so that it is possible to obtain a screw that is strong against wind from the lateral direction and has excellent strength and rigidity, and The use of the first and second screws 42 and 42A can be expected to greatly improve the bonding and fixing strength of the wall panel. In particular, when SP-120 is used as the first and second screws 42 and 42A, it is possible to obtain a holding power and high reliability that are three to four times as compared with ordinary screws.

  Further, the sealing material 37 is filled in the gap 15 between the lower lower surface of the gypsum board 13 and the flooring 36 instead of simply contacting the lower lower surface of the gypsum board 13 and the flooring 36, so that the moisture-proof and airtight film 20 and the sealing material 37 are filled. Ensuring sufficient airtightness can be expected through the multilayer structure.

  In addition, the wall frame 1 of the said embodiment can be formed in a rectangle or a square, and the number of the crosspieces 5 and the crosspieces 6 can be increased / decreased suitably. Further, other layers may be appropriately interposed between the wall frame 1 and the structural plywood 10 and / or between the wall frame 1 and the gypsum board 13. Moreover, in the said embodiment, although the liquid sealing material 37 was filled into the clearance gap 15 between the lower lower surface of the gypsum board 13, and the flooring 36, it is not limited to this at all. For example, a fixed sealing material may be used.

  Further, when joining a plurality of wall panels side by side, the side portions of the moisture-proof and air-tight film 20 may be sandwiched between adjacent wall panels to improve dehumidification, waterproofness, and airtightness (FIG. 13). reference). Furthermore, the wall panel can be used not only for each part of the first floor but also for construction of each part of the second floor.
