  The present invention relates to a load bearing wall used in buildings such as wooden structures and steel structures.

  As a bearing wall, a rectangular space formed by a base member extending in the horizontal direction, a pair of column members extending in the vertical direction, and a beam member extending in the horizontal direction is composed of a plurality of lattice ribs in the vertical direction and the horizontal direction. The thing which has arrange | positioned the panel material made from a synthetic resin is proposed (for example, refer patent document 1).

JP 2006-77565 A

  However, in the load-bearing wall described in Patent Document 1, since the panel material is composed of longitudinal and lateral lattice ribs, the panel material is deformed when an oblique load is applied, and the wall is distorted as a whole.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a lightweight and small bearing wall capable of accurately resisting loads in all directions.

  In order to achieve the above object, in the present invention, a base member extending in the left-right direction, a pair of column members extending upward from the base member and provided at intervals in the extending direction of the base member, and each of the columns A bearing wall having a beam member connected to the upper end side of the member and extending in the left-right direction, in a rectangular space in front view formed by the base member, each column member, and the beam member, in a predetermined front-rear direction A core member obtained by bending a long sheet-like reinforcing fiber plastic material having a width dimension so as to form a plurality of closed cross sections in a front view, and a plate-like reinforcing fiber plastic material closing the front end of the core member There is provided a load bearing wall in which a reinforcing panel including a front blocking member and a rear blocking member including a plate-like reinforcing fiber plastic material blocking the rear end of the core member is disposed.

  According to this bearing wall, the core member of the reinforced panel is curved so as to form a plurality of closed cross sections when viewed from the front, so that the core member can accurately match the loads in all directions as long as it is in the in-plane direction of the reinforced panel. Can withstand. In addition, since the core member is blocked by the front blocking member and the rear blocking member, the bending rigidity of the reinforced panel is not impaired. Furthermore, since the core member, the front closing member, and the rear closing member are configured to include the reinforcing fiber plastic material, the reinforcing panel can be reduced in weight and size while imparting relatively high strength to the reinforcing panel.

  In the load bearing wall, each of the closed cross sections may be substantially circular in a front view.

  According to this load-bearing wall, since each closed cross section of the core member is substantially circular, it is possible to almost uniformly resist loads in all directions in the in-plane direction of the reinforcing panel.

  In the load-bearing wall, each closed section is aligned with the intersection of the virtual triangular lattice at a predetermined cycle so that the center of the circle forming the closed section is the position of the apex of the regular triangle in front view. It may be arranged.

  According to this load-bearing wall, adjacent to the outside of each closed section, the six closed sections are arranged at intervals of 60 degrees in the circumferential direction, whereby each closed section can be densely arranged in a front view.

  In the load-bearing wall, the core member is composed of a single unit of the reinforcing fiber plastic material, and the unit cores formed continuously while vertically shifting the closed cross sections in two rows in the left-right direction. You may comprise by arranging two or more in a direction.

  According to this bearing wall, although each closed cross section becomes an incomplete circle, the core member can be produced efficiently.

  In the bearing wall, the reinforcing fiber plastic material of the core member may be formed in a sheet shape having a thickness of less than 3.0 mm.

  According to this load-bearing wall, the reinforcing panel can be made extremely light by making the core member a sheet having a thickness of less than 3.0 mm, and the handling of the strengthening panel and the load-bearing wall is facilitated.

  In the load-bearing wall, the distance between the centers of the column members in a front view may be 450 mm or more and 460 mm or less.

  According to this load-bearing wall, a building such as a house is generally designed with a distance between the centers of each column member as a reference dimension of about 910 mm. It can be around half and can be used in general standard dimensions of buildings.

  In the load-bearing wall, the reinforcing panel may be fixed to the column members by a plurality of fixing members extending in the front-rear direction and arranged in the up-down direction.

  According to this load-bearing wall, the left and right outer sides of the reinforcing panel are fixed to the column members by the fixing members arranged vertically, so that the reinforcing panel can be fixed integrally to the column members and added to the load-bearing wall. Can withstand loads effectively.

  In the load-bearing wall, the reinforcing panel may be disposed at a distance from the base member and the beam member.

  According to this load-bearing wall, since the reinforcing panel is disposed independently of the base member and the beam member, the reinforcing panel is restrained by the base member and the beam member, and an excessive load is not applied to the reinforcing panel. Further, the compressive force in the vertical direction does not act directly on the reinforcing panel 50 from the base member 10 and the beam member 30.

  According to the bearing wall of the present invention, it is possible to accurately resist loads in all directions while being lightweight and small.

  1 to 4 show an embodiment of the present invention, and FIG. 1 is a schematic front view of a load bearing wall.

  As shown in FIG. 1, the load-bearing wall 1 includes a base member 10 that extends in the left-right direction, and a pair of column members 20 that extend upward from the base member 10 and are provided at intervals in the extending direction of the base member 10. The beam member 30 is connected to the upper end side of each column member 20 and extends in the left-right direction. In addition, although the installation direction of the load-bearing wall 1 in a building is arbitrary, the extension direction of the base member 10 and the beam member 30 is prescribed | regulated as a left-right direction, and is demonstrated. A space 40 having a square shape in front view is formed in the bearing wall 1 by the base member 10, the column members 20, and the beam members 30. The bearing wall 1 is disposed in the space 40 and has a reinforcing panel 50 mainly made of a reinforcing fiber plastic material.

  The base member 10 is made of wood and has a quadrangular cross section when viewed from the side. On the upper surface of the base member 10, a pair of mortises 11 having a square shape in a top view are formed. In this embodiment, as the wood of the base member 10, a square member having a front-rear dimension of 105 mm and a vertical dimension of 105 mm is used. In addition, an upper surface reinforcing plate 12 is provided in a contact portion with each column member 20 on the upper surface of the base member 10. The upper surface reinforcing plate 12 is made of metal, for example.

  Each column member 20 is made of wood and has a quadrangular cross section in plan view. A lower tenon 21 that fits into the tenon 11 of the base member 10 is formed at the lower end of each column member 20. Further, an upper tenon 22 that fits into a tenon 31 of a beam member 30 described later is formed at the upper end of each column member 20. A receiving hole 23 that extends in the vertical direction and receives the outer end of the reinforcing panel 50 is formed on the inner side surface of each column member 20. In the present embodiment, as the wood of each column member 20, a square member having a front-rear dimension of 105 mm and a left-right dimension of 150 mm is used. The distance A between the centers of the column members 20 in the front view is arbitrary, but is, for example, not less than 450 mm and not more than 460 mm, and is 455 mm in the present embodiment.

  The beam member 30 is made of wood and has a quadrangular cross section when viewed from the side. On the lower surface of the beam member 30, a pair of mortises 31 having a quadrilateral view are formed. In the present embodiment, a square member having a longitudinal dimension of 105 mm and a vertical dimension of 105 mm is used as the wood of the beam member 30. The distance C between the base member 10 and the beam member 30 in the front view is arbitrary, but is, for example, 2600 mm or more and 2900 mm or less, and in this embodiment, 2820 mm.

  As shown in FIG. 2, the reinforcing panel 50 is formed to have a predetermined front-rear thickness and is connected to each column member 20. In the present embodiment, the reinforcing panel 50 is disposed at a distance from the base member 10 and the beam member 30. Although the thickness of the reinforced panel 50 is arbitrary, it can be 20 mm or more and 40 mm or less, for example, and is 30 mm in this embodiment. Moreover, in this embodiment, the left-right dimension of the reinforcement panel 50 is 405 mm, and an up-down dimension is 2620 mm. The reinforcing panel 50 includes a core member 52 made of a sheet-like reinforcing fiber plastic material, a front closing member 53 made of a plate-like reinforcing fiber plastic material closing the front end side of the core member 52, and a rear end side of the core member 52. And a rear-side closing member 54 made of a plate-like reinforcing fiber plastic material. Although the thickness of the core member 52, the front side blocking member 53, and the rear side blocking member 54 is arbitrary, the thickness of the core member 52 can be 18 mm or more and 36 mm or less, for example, the front side blocking member 53 and the rear side blocking member 54 The thickness of the member 54 can be 1.0 mm or more and 2.0 mm or less, respectively.

  As shown in FIG. 3, the core member 52 is formed by bending a long sheet-like reinforcing fiber plastic material having a predetermined front-rear width dimension so as to form a plurality of closed sections 55 in a front view. . In the present embodiment, each closed section 55 is substantially circular in front view. Note that the shape of each closed section 55 can be changed as appropriate, and may be, for example, elliptical. Further, as shown in FIG. 3A, in the present embodiment, each closed cross-section 55 is predetermined so that the center of the circle forming the closed cross-section 55 is the position of the apex of the equilateral triangle in front view. Are arranged in alignment with the intersections of the virtual triangular lattice T with a period of. That is, each closed section 55 is regularly arranged so that one closed section 55 is surrounded by six closed sections 55. Thereby, adjacent to the outside of each closed cross-section 55, the 6 closed cross-sections 55 are arranged at intervals of 60 degrees in the circumferential direction, whereby each closed cross-section 55 can be densely arranged in a front view. The arrangement state of each closed section 55 can be appropriately changed. For example, each closed section 55 is aligned with the intersection of virtual square lattices at a predetermined cycle so that the center is the position of the apex of the square. It can also be arranged.

  In the present embodiment, the core member 52 has a plurality of unit cores 56 made of sheets 51 of reinforced fiber plastic material. Although the thickness of the sheet | seat 51 is arbitrary, it is preferable to set it as less than 3.0 mm, More preferably, it is less than 1.0 mm, and is 0.5 mm in this embodiment. Moreover, although the circular diameter dimension of each closed cross-section 55 is also arbitrary, it can be 10 mm or more and 40 mm or less, and is 36 mm in this embodiment. Each unit core 56 is continuously formed by one sheet 51 while vertically shifting the closed cross sections 55 in two rows in the left-right direction. The core member 52 is configured by arranging a plurality of unit cores 56 in the vertical direction. Thereby, although each closed cross-section 55 becomes an incomplete circle, the core member 52 can be produced efficiently.

  The front blocking member 53 and the rear blocking member 54 are each made of a reinforced fiber plastic material, and the core member 52 is entirely bonded. The reinforcing panel 50 is configured by sandwiching a core member 52 by a front closing member 53 and a rear closing member 54. In the present embodiment, the front blocking member 53 and the rear blocking member 54 are translucent. By making the front blocking member 53 and the rear blocking member 54 transparent or translucent materials, light can be taken into the room through the reinforcing panel 50. In this case, a lighting device for taking light into the room through the front blocking member 53 and / or the rear blocking member 54 is provided as necessary. The left and right outer sides of the reinforcing panel 50 are fitted into the receiving holes 23 of the column members 20 via an adhesive. This adhesive can be omitted.

  The reinforcing panel 50 is fixed to each column member 20 by a plurality of fixing members 60 that extend in the front-rear direction and are arranged in the up-down direction. In the present embodiment, a metal drift pin is used as the fixing member 60. The material of the fixing member 60 is arbitrary, and can be made of resin, for example. Further, as the fixing member 60, for example, a nail may be used in addition to the pin member. In this manner, the left and right outer sides of the reinforcing panel 50 are fixed to the column members 20 by the fixing members 60 arranged in the vertical direction, so that the reinforcing panel 50 can be fixed integrally to the column members 20 and the bearing wall It is possible to effectively resist the load applied to 1. That is, each column member and the panel material are not fixed integrally as in the case where the four corners of the panel material are fixed to the base member, each column member, and the beam member, and can sufficiently resist the load applied to the bearing wall 1. There is nothing that cannot be done. As shown in FIG. 1, the interval B between the fixing members 60 in the reinforcing panel 50 can be set to 150 mm or more and 300 mm or less. Thereby, the reinforcement panel 50 can be accurately fixed to each column member 20 without restraining it excessively. Specifically, if the interval B is less than 150 mm, the reinforcing panel 50 is liable to crack when a load is applied to the bearing wall 1, and if the interval B is greater than 300 mm, the reinforcing panel 50 and the column member 20 move relatively. It becomes easy. Note that the upper and lower ends of the reinforcing panel 50 are firmly fixed by two fixing members 60 close to each other in the vertical direction.

  According to the load-bearing wall 1 configured as described above, since the core member 52, the front blocking member 53, and the rear blocking member 54 are configured to include the reinforcing fiber plastic material, the reinforcing panel 50 has a relatively high strength. The reinforcing panel 50 can be reduced in weight and size while being applied. According to the present embodiment, the reinforcing panel 50 can be made extremely lightweight by using the core member 52 as the sheet 51 having a thickness of less than 3.0 mm, and the handling of the reinforcing panel 50 and the load bearing wall 1 is facilitated.

  When the magnification test was performed on the bearing wall 1 of the present embodiment with the distance A between the centers of the column members 20 set to 455 mm, the distance between the centers of the column members provided with wood panels on the column members was 910 mm. It was confirmed that the wall magnification was equal to or greater than the bearing wall. In general, a building such as a house is often designed with a reference dimension of about 910 mm for the distance between the centers of the pillar members, and the bearing wall 1 of the present embodiment is about 455 mm, which is half of this reference dimension. Can be used in the general standard dimensions of buildings. For example, if a wall magnification equivalent to that of a conventional bearing wall is required within the reference dimension, it is only necessary to provide one bearing wall 1 according to the present embodiment within the reference dimension. In this case, it is possible to reduce the space where the bearing wall is provided in the building, and the remaining space can be used as another space such as a window or a living room, and the design freedom in the building is dramatically improved. Further, for example, it is possible to dramatically improve the wall magnification within the reference dimension by providing two bearing walls 1 of the present embodiment within the reference dimension.

  Moreover, according to the load-bearing wall 1 of this embodiment, since the core member 52 of the reinforced panel 50 is curved so as to form a plurality of closed cross sections 55 in a front view, the in-plane direction of the reinforced panel 50 is The core member 52 can accurately resist loads in all directions. In particular, since each closed cross-section 55 has a substantially circular shape, it is possible to almost uniformly resist loads in all directions in the in-plane direction of the reinforcing panel 50. Further, since the core member 52 is blocked by the front blocking member 53 and the rear blocking member 54, the bending rigidity of the reinforcing panel 50 is not impaired.

  Furthermore, according to the load-bearing wall 1 of the present embodiment, the reinforcing panel 50 is disposed independently of the base member 10 and the beam member 30, so that the reinforcing panel 50 is restrained by the base member 10 and the beam member 30, An excessive load is not applied to the reinforcing panel 50. Further, the compressive force in the vertical direction does not act directly on the reinforcing panel 50 from the base member 10 and the beam member 30.

  Moreover, by providing the upper surface metal plate 12, it is possible to prevent the pillar members 20 from being sunk into the base member 10 when a load is generated. The reinforcing panel 50 of the present embodiment has a relatively high strength, and the load tends to concentrate on the connecting portion between each column member 20 and the base member 10, so that reinforcement by the upper surface metal plate 12 is extremely effective.

  In the above embodiment, the base member 10, each column member 20, and the beam member 30 are made of wood. However, other materials such as iron and steel may be used.

  While the embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. In addition, it should be noted that not all the combinations of features described in the embodiments are essential to the means for solving the problems of the invention.
