Description

Technical Field

[0001] The present invention relates to a wooden house, and more particularly to a shear wall structure, a shear wall construction method, and a shear wall panel of a wooden house constructed by a wooden frame construction method.

Background Art

[0002] Conventionally, in a wooden house constructed by a wooden frame construction method using a foundation, columns, and horizontal members such as beams and girders, for example, a shear panel is attached so as to block an opening surrounded by two columns, a foundation, and horizontal members from the outside. The shear panel is fixed by being nailed to two columns, a foundation, and a beam at a constant pitch along its outer peripheral edge.

[0003] However, in a wooden house constructed by a wooden frame construction method using a shear panel, strong forces due to repeated earthquakes, typhoons, etc. during long-term residence act on the building structure, the nails fixing the shear panel become loose, or rust occurs due to internal condensation, resulting in a reduction in the function of the shear panel. As a result, the frame structure is deformed, and problems such as cracking of the exterior material and intrusion of rainwater into the interior occur.

[0004] Patent Document 1 describes a shear wall in which a cut having a depth substantially equal to the thickness of an outer structural plate is formed around an opening formed by columns, a foundation, and horizontal members, the peripheral edge of the outer structural plate is fitted into this cut, and it is fixed by fixing means such as nails. Patent Document 2 describes a shear ceiling wall and a shear floor wall having the same structure as that of Patent Document 1. Patent Document 3 describes a wall structure in which a recess having a depth corresponding to the thickness of a shear panel is formed in a structural member to which the shear panel is fixed, and the outdoor side surface of the shear panel is on the same plane as the outdoor side surface of the structural member.

[0005] However, the structures of Patent Documents 1 to 3 do not have sufficient overlap between the shear wall and the cut or recess into which the shear wall is fitted, the distance from the edge to the nailing position is insufficient, making nailing difficult, and the strength cannot be said to have been improved. Also, there was still a problem that the nails fixing the shear panel became loose against the torsion of the building structure.

[0006] Patent Document 4 describes a building panel having a honeycomb core in which a metal honeycomb core is interposed between a metal front panel and a back panel. Patent Document 5 describes a honeycomb panel in which a core material made of aluminum is interposed between a pair of opposing metal plates serving as front panels, and reinforcing ribs are erected on at least one surface of the honeycomb panel. Patent Document 6 describes a building panel in which a straight member having a U-shaped cross section composed of one web and two flanges is formed into a regular hexagonal load-bearing unit by cutting the flanges at five locations and bending the web, and this load-bearing unit is arranged to form a honeycomb structure in a frame member composed of a horizontal member and a vertical member.

[0007] However, the structures of Patent Documents 4 - 6 have problems in that since the honeycomb core is made of metal, it involves bending and joining processes, making manufacturing difficult, and also taking a long time and high cost for manufacturing.

Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0014] FIG. 1 shows a wooden house 1 to which a shear wall 2 according to an embodiment of the present invention is applied. The wooden house 1 is assembled by a wooden frame construction method using a foundation 3, a base 4, columns 5, and horizontal members 6 such as beams 6a and girders 6b (hereinafter, these are referred to as "frame members"). Between the two columns 5, a body connecting member 7 and an intermediate column 8 are provided as necessary. Note that the frame members include window frames and door frames.

[0015] An opening 9 surrounded by two columns 5, 5 (first and second frame members), a base 4, and a horizontal member 6 (third and fourth frame members) is closed by a double (double) shear wall 2 composed of a honeycomb core 11 and a shear surface material 12, or a conventional single (single) shear wall 10. Double (double) shear walls 2 are provided in the openings 9 including the columns 5 at the four corners of the first and second floors, and single (single) shear walls 10 are provided in the other openings 9. On the outdoor side of the shear walls 2, 10, exterior materials such as siding are provided via a waterproof sheet (not shown), and on the indoor side, interior materials are provided via a heat insulating material (not shown).

[0016] As shown in Fig. 2, the honeycomb core 11 that constitutes the inner wall of the double shear wall 2 has a plurality of honeycomb units 11a arranged in a honeycomb shape when viewed from the thickness direction of the shear wall 2 inside the rectangular opening 9 surrounded by the two columns 5, 5, the base 4, and the horizontal member 6. That is, on the base 4 between the two columns 5, 5, two honeycomb units 11a and one honeycomb unit 11a are alternately arranged upward to near the horizontal member 6. The honeycomb unit 11a is arranged with one corner facing down. The lower corners of the two adjacent honeycomb units 11a in the first row in the horizontal direction are in contact with the base 4, the opposing vertical sides are in contact with each other, and the vertical sides on the opposite side are in contact with the columns 5, 5. The lower diagonal side of the honeycomb unit 11a in the second row is in contact with the upper diagonal side of the two honeycomb units 11a in the first row. The lower diagonal sides of the two honeycomb units 11a in the third row are in contact with the upper diagonal side of the honeycomb unit 11a in the second row, the opposing vertical sides are in contact with each other, and the vertical sides on the opposite side are in contact with the columns 5, 5. The honeycomb units 11a from the fourth row and later are arranged in the same way.

[0017] The honeycomb unit 11a is made of wood and, as shown in Fig. 3, is formed by combining six trapezoidal blocks 13 cut from waste materials of frame members such as columns into a regular hexagon and joining them with screws (or bolts) 14. The trapezoidal blocks 13 may be joined with an adhesive. By combining three trapezoidal blocks 13, a half honeycomb unit 11b can also be formed. The two ends of the half honeycomb unit 11b may be joined with wooden connecting pieces 13a to form a reinforced half honeycomb unit 11b'. The half honeycomb unit 11b can be used to fill the spaces on both sides of the honeycomb units 11a in the second, fourth, and sixth rows in Fig. 2.

[0018] When two honeycomb units 11a are arranged between columns 5, 5, the core-to-core dimension S between columns 5, 5 is 910 mm, the thickness T of columns 5, 5 is 105 mm, the surface-to-surface dimension W of honeycomb unit 11a is (S - T) / 2 = (910 - 105) / 2 = 402.5 mm, the corner-to-corner dimension H is (W / 2) / √3 x 4 = 201.25 / √3 x 4 = 464.8 mm, and the length L of the bottom surface of trapezoidal block 13 is (W / 2) / √3 x 2 = 201.25 / √3 x 2 = 232.4 mm. Also, the thickness T of honeycomb unit 11a is the same as the thickness of columns 5, 5, which is 105 mm, but it may be less than that.

[0019] The load-bearing surface material 12 that constitutes the outer wall of the double load-bearing wall 2 has a rectangular shape larger than the opening 9 surrounded by two columns 5, 5, the base 4, and the horizontal members 6. The thickness is 28 mm in the embodiment, but it is not limited to this. As the load-bearing surface material 12, Mois (registered trademark) manufactured by Aitek Building Materials Co., Ltd. is preferable. The outer peripheral edge of the load-bearing surface material 12 is fixed by nailing nails 15 to two columns 5 (the first and second axis assembly members), the base 4, and the horizontal members 6 (the third and fourth axis assembly members).

[0020] The single load-bearing wall 10 has the same shape as the load-bearing surface material 12 of the double load-bearing wall 2 and is a load-bearing surface material (the third load-bearing surface material of the present invention) of the same material. Its outer peripheral edge is fixed by nailing to two columns 5 (the first and second axis assembly members), the base 4, and the horizontal members 6 (the third and fourth axis assembly members).

[0021] Next, the construction procedure of the load-bearing wall 2 of the wooden house 1 according to the embodiment of the present invention will be described.

[0022] As shown in FIG. 1, on the foundation 3, the wooden house 1 is assembled by the wooden frame construction method using the base 4, columns 5, and horizontal members 6 (axis assembly members) such as beams and girders. Between the two columns 5, body connecting members 7 and intermediate columns 8 are provided as necessary.

[0023] As shown in Fig. 4, two honeycomb units 11a of the first stage are installed on the base 4 of the opening 9 provided with the double shear walls 2. Here, the isosceles triangle gap and the right triangle gap between the honeycomb unit 11a and the base 4 may be filled with triangular blocks cut from waste materials to disperse the load. Also, as shown in Fig. 5(a), a groove 4a into which the corner of the honeycomb unit 11a fits may be formed in the base 4 where the corner of the honeycomb unit 11a hits, or as shown in Fig. 5(b), a chamfer 11c may be provided at the corner of the honeycomb unit 11a so that the load does not concentrate on the base 4. Subsequently, one honeycomb unit 11a of the second stage is installed on the two honeycomb units 11a of the first stage, and two honeycomb units 11a of the third stage are installed on the one honeycomb unit 11a of the second stage, and this is repeated until it is arranged near the horizontal member 6. Next, a body connecting member 7 is provided so as to contact the upper corner of the topmost honeycomb unit 11a. Both ends of the body connecting member 7 are joined to the column 5 by joining parts K1 such as, for example, Tekwan (registered trademark) jaw fittings and drift pins. The isosceles triangle gap and the right triangle gap between the honeycomb unit 11a and the body connecting member 7 may be filled with triangular blocks cut from waste materials to disperse the load in the same manner as the gap of the base 4. By installing the honeycomb units 11a as described above and assembling the honeycomb core 11, the outer surface on the outdoor side of the honeycomb core 11 is flush with the horizontal members 6 (framing members) such as the base 4, the column 5, the beam, and the girder.

[0024] Next, a shear-resistant facing material 12 is arranged so as to overlap the honeycomb core 11, and the outer peripheral edge of the shear-resistant facing material 12 is nailed to the horizontal members 6 (framing members) such as the base 4, the column 5, the beam, and the girder as shown in Figs. 6 and 7. Nailing is preferably performed at a constant pitch of 100 mm or less at a position more than the thickness of the shear-resistant facing material 12 (for example, 12 mm) away from the edge of the shear-resistant facing material 12. When there is an intermediate column 8 or a body connecting member 7 between the two columns 5, nailing is performed along them at a pitch twice the outer circumference.

[0025] For the opening 9 where the single shear wall 10 is provided, a shear wall material similar to the shear wall material 12 is arranged, and in the same manner as the shear wall material 12 of the double shear wall 2, the outer peripheral edge is nailed to the foundation 4, columns 5, beams, girders and other horizontal members 6 (framing members).

[0026] As shown in FIG. 2, the honeycomb cores 11 that make up the shear wall 2 constructed in this way are such that the honeycomb units 11a are in contact with each other and are also in contact with the columns 5, 5, the foundation 4, and the body connecting members 7. Therefore, the strength against the external force that causes the columns 5, 5, the foundation 5, and the horizontal members 6 to deform into a parallelogram due to external forces such as earthquakes is high. Also, since the honeycomb core 11 and the shear wall material 12 overlap each other, the external force acting on the shear wall 2 is dispersed to the honeycomb core 11 and the shear wall material 12, and the strength against displacement in the direction perpendicular to the surface is high. Thus, due to the synergistic effect of the honeycomb core 11 and the shear wall material 12, the shear wall 2 in this embodiment has high strength as a shear wall, has strong resistance against external forces caused by earthquakes and typhoons, the strength as a shear wall is improved, and the loosening of the nails 15 is prevented.

[0027] Also, since the double shear wall 2 composed of the honeycomb core 11 and the shear wall material 12 is mainly arranged and attached to the openings 9 on the sides including the columns 5 at the four corners of the wooden house, it can effectively resist the external force acting on the entire structure of the wooden house.

[0028] Furthermore, since the honeycomb core 11 is composed of a plurality of honeycomb units 11a formed by combining six trapezoidal blocks 13 cut from waste framing members into a regular hexagon, there is no need to discard or incinerate the waste materials, which is friendly to the global environment. In addition, it makes effective use of waste materials and can contribute to the achievement of the SDGs goals. Also, since the honeycomb core 11 is made of wood and there is no condensation inside the wall, there is no mold growth, and rust does not occur on the nails for attaching the shear wall material 12.

[0029] FIG. 8 shows a first modification of the arrangement of the honeycomb units 11a of the honeycomb core 11. In this first modification, two honeycomb units 11a of the first stage are arranged on the base 4, and one honeycomb unit 11a of the second stage is arranged thereon, and then two honeycomb units 11a of the third stage are arranged thereon, and then the first body connecting member 7a is attached. Further, two honeycomb units 11a of the fourth stage are arranged on the first body connecting member 7a, and one honeycomb unit 11a of the fifth stage is arranged thereon, and then two honeycomb units 11a of the sixth stage are arranged thereon, and then the second body connecting member 7b is attached. Both ends of the first and second body connecting members 7 are joined to the column 5 by joining parts K1 such as, for example, a jaw mounting bracket of Tech One (registered trademark) and a drift pin.

[0030] FIG. 9 shows a second modification of the arrangement of the honeycomb units 11a of the honeycomb core 11. In this second modification, one side surface of the honeycomb unit 11a is arranged downward. The lower side surfaces of two adjacent honeycomb units 11a spaced apart in the horizontal direction of the first stage are in contact with the base 4, the left and right opposing corners are spaced apart from each other, and the opposite corners are in contact with the columns 5, 5. The lower diagonal side surface of one honeycomb unit 11a of the second stage is in contact with the upper diagonal side surface of the two honeycomb units 11a of the first stage. The lower side surfaces of the two honeycomb units 11a of the third stage are in contact with the upper side surfaces of the honeycomb units 11a of the first stage, and the lower diagonal side surfaces are in contact with the upper diagonal side surfaces of the second stage. The honeycomb units 11a after the fourth stage are arranged in the same manner. It is preferable to arrange half honeycomb units 11b between the two honeycomb units 11a of the first stage and on both sides of the one honeycomb unit 11a at the uppermost stage. Further, a body connecting member 7 is provided on the honeycomb unit 11a at the uppermost stage. Both ends of the body connecting member 7 are joined to the column 5 by joining parts K1 such as, for example, a jaw mounting bracket of Tech One (registered trademark) and a drift pin.

[0031] In the above embodiment, the honeycomb unit 11a is directly arranged and attached between the columns 5, 5. However, a shear wall panel 16 as shown in FIG. 10 may be formed in advance, and this shear wall panel 16 may be fitted between the columns 5, 5.

[0032] The shear wall panel 16 shown in FIG. 10 is composed of a rectangular frame 17 and a honeycomb core 11. The frame 17 is composed of vertical first and second frame members 17a and 17b parallel to each other, and horizontal third and fourth frame members 17c and 17d parallel to each other and orthogonal to the first and second frame members 17a and 17b. Similar to the above embodiment, the honeycomb core 11 has a plurality of honeycomb units 11a formed by combining six trapezoidal blocks 13 in a regular hexagon. The honeycomb units 11a are arranged in a honeycomb shape when viewed from the thickness direction of the shear wall panel 16 inside the rectangular frame 17 surrounded by the first and second frame members 17a and 17b and the third and fourth frame members 17c and 17d. Further, a body connecting member 7 is provided above the uppermost honeycomb unit 11a. It is preferable that the honeycomb units 11a are joined to each other by joining components K2 such as Tech One (registered trademark) hozo pipes, drift pins, and wooden plugs (commisen). It is preferable that the honeycomb core unit 11a and the frame 17, and the body connecting member 7 and the frame 17 are joined by joining components K3 such as Tech One (registered trademark) jaw hanging brackets and drift pins.

[0033] This shear wall panel 16 can be fitted between the columns 5 of an existing house, and the frame 17 and the column 5 can be fixed by appropriate joining means and used for seismic reinforcement. Since the honeycomb units 11a are joined to each other and the honeycomb units 11a and the frame 17, it is not necessary to provide a shear wall surface material 16 as shown in FIG. 2. Covers made of glass or plastic can be detachably attached to the central space of the honeycomb unit 11a and the space between the honeycomb unit 11a and the frame, and the air-conditioned air from the air conditioner can be circulated by removing the cover.

[0034] The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention described in the claims.

[0035] For example, in the above embodiment, the double shear walls 2 are applied to the openings 9 of the side walls including the columns 5 at the four corners of the wooden house 1. However, when there is a window frame in the opening 9 of the side wall including the columns 5 at the four corners, the double shear walls 2 can be attached above and below the window frame. When there is a door frame, the double shear walls 2 can be attached to the opening 9 adjacent to the door frame. Further, it is preferable that the double shear walls 2 are provided in all of the four openings 9 of the side walls including the columns 5 at the four corners (projecting corners). However, due to the structure of the building, if there are circumstances where the double shear walls 2 cannot be provided in the opening 9, the attachment of the shear walls 2 to that opening 9 may be omitted. When there are corner columns 5, the double shear walls 2 may also be provided in the openings 9 of the side walls including the corner columns 5.

[0036] As described below, the double shear walls 2 of the present invention can also be applied to the floor walls on the first floor and the ceiling walls (which are also the floors on the second floor).

[0037] As shown in Fig. 11(a), in the case of the floor shear wall 21 applied to the floor wall, notches 18 are provided at the peripheries of the openings 9 surrounded by the four bases 4 adjacent to the columns 5 at the four corners of the wooden house 1. The support plates 19 are fitted into these notches 18. After the honeycomb cores 11 are arranged on these support plates 19, the load-bearing surface materials 12 are stacked and nailed with nails 15.

[0038] As shown in Fig. 12(a), in the case of the ceiling shear wall 22 applied to the ceiling wall, similar to the case of the floor shear wall 21, notches 18 are provided at the peripheries of the openings 9 surrounded by the two beams 6a and the two girders 6b adjacent to the columns 5 at the four corners. The support plates 19 are fitted into these notches 18. After the honeycomb cores 11 are arranged on these support plates 19, the load-bearing surface materials 12 are stacked and nailed with nails 15. In the case of the floor shear wall 21 or the ceiling shear wall 22, it is preferable to provide notches 20a and 20b at the four corners of the support plate 19 and the load-bearing surface material 12 so as not to interfere with the columns 5 and the studs 8.

[0039] Thus, since the double shear walls 21 and 22 composed of the honeycomb core 11 and the shear panel 12 are importantly arranged and attached to the openings 9 in the first floor floor surface or ceiling surface (second floor floor surface) adjacent to the columns 5 at the four corners of the wooden house, it is possible to efficiently resist the external force applied to the entire structure of the wooden house.

[0040] In the above embodiment, the honeycomb unit 11a and the column 5 or the horizontal member 6 are in surface contact. However, as shown in FIG. 13, of the left and right honeycomb units 11a, a convex portion 11d is formed on the vertical side surface facing the column 5 of the left honeycomb unit 11a, and a concave portion 11e is formed on the opposite side surface. A convex portion 11d is formed on the vertical side surface facing the column 5 of the right honeycomb unit 11a, and a convex portion 11d is also formed on the opposite side surface. The convex portions 11d of the left and right honeycomb units 11a are fitted into the concave grooves 5a formed in the column 5 in the vertical direction, and the concave portion 11e of the left honeycomb unit 11a and the convex portion 11d of the right honeycomb unit 11a may be fitted together.
