Description

Technical Field

[0001] The present invention relates to a reinforcing wall.

Background Art

[0002] Patent Document 1 discloses a seismic panel that is inserted into an opening of a frame structure and attached to the frame structure in order to improve the seismic resistance of the frame structure. This seismic panel includes a rectangular thin plate, front and back frames, and a plurality of fire striking plates on the front and back. Four fire striking plates on the front side are respectively welded to the four corners inside the front frame, and four fire striking plates on the back side are respectively welded to the four corners inside the back frame. The front frame is in surface contact with the front of the thin plate along the entire circumference of the thin plate, and the back frame is in surface contact with the back of the thin plate along the entire circumference of the thin plate. The front frame and the back frame sandwich the thin plate by the fastening force of bolts and nuts. The four fire striking plates on the front side are respectively in surface contact with the front of the thin plate at the four corners of the thin plate, and the four fire striking plates on the back side are respectively in surface contact with the back of the thin plate at the four corners of the thin plate. The fire striking plates on the front side and the fire striking plates on the back side sandwich the thin plate by the fastening force of bolts and nuts. The thin plate elastically deforms with respect to shaking having a magnitude below a predetermined value. The thin plate plastically deforms with respect to shaking having a magnitude exceeding the predetermined value. Such deformation reduces the load applied to the frame structure.

[0003] If the structure has been in existence for many years since completion, the frame structure may be distorted. The distortion of the frame structure causes non-parallelism between columns and non-parallelism between beams. Therefore, the seismic panel disclosed in Patent Document 1 cannot be easily installed on a distorted frame structure.

[0020] Embodiments will be described below with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The scope of the present invention is not limited to the examples in the drawings, as the drawings are provided for illustrative purposes only.

[0021] <1. Buildings> Figure 1 is a cross-sectional view of building 1.

[0022] Building 1 is a temple or shrine building that has been standing for many years since its completion. Building 1 is a wooden stone building constructed using traditional construction methods. Building 1 has multiple columns 2 and multiple horizontal members 5 that are framed using timber framing methods. Horizontal members 5 refer to girders, main beams, secondary beams, rainbow beams, lintels, head beams, tie beams, lintels, or foot braces. The columns 2 and horizontal members 5 are collectively called framing members. At the joints between the columns 2 and horizontal members 5, the columns 2 and horizontal members 5 are joined by mortise and tenon joints, dovetail joints, or through-beams, so Building 1 can be said to be a flexible structure. The columns 2 are erected on foundation stones 3. The columns 2 may not be tightly fastened to the foundation stones 3 and may be dynamically insulated from the foundation stones 3. The lower ends of the columns 2 may be joined to the foundation stones 3 with dowels. In other words, the dowel is installed at the upper end of the foundation stone 3, a dowel hole is formed at the lower end of the column 2, and the dowel may be fitted into or loosely fitted into the dowel hole.

[0023] Building 1 is a temple or shrine building that has been standing for many years, and as a result of age-related deterioration, it has become weak against earthquakes. Therefore, Building 1 is seismically reinforced with multiple reinforcing walls. The reinforcing walls are installed in parts of Building 1 that lack sufficient seismic resistance. The reinforcing walls are installed between adjacent columns 2. The columns 2 on both sides of the reinforcing wall may be located on the outer perimeter of Building 1, and the reinforcing wall may be an exterior wall. The columns 2 on one or both sides of the reinforcing wall may be located on the inside of the outer perimeter of Building 1, and the reinforcing wall may be an interior wall (partition wall). If an existing wall, such as an earthen wall, is installed between adjacent columns 2, the existing wall may be removed and the reinforcing wall may be installed in its place.

[0024] <2. Reinforcement Wall> Figure 2 is a front view of the reinforcing wall 10 installed between adjacent columns 2. Figure 3 is a vertical cross-sectional view along the line III-III shown in Figure 2. Figure 4 is a vertical cross-sectional view along the line IV-IV shown in Figure 3. Figure 5 is a horizontal cross-sectional view along the line VV shown in Figures 3 and 4.

[0025] The reinforcing wall 10 may be used as a small wall, a low wall, or a hanging wall. The reinforcing wall 10 comprises six wooden panels 20, an inner frame 30, an outer frame 40, a front facing material 50, and a back facing material 60.

[0026] The wood panels 20 are structural materials. When constructing the reinforcing wall 10, the wood panels 20 are manufactured in advance at a factory and transported from the factory to the construction site of building 1. Because the wood panels 20 are manufactured at a factory, they have high load-bearing capacity, strength, durability, and quality.

[0027] The wooden panel 20 comprises a pair of vertical frame members 21, a pair of horizontal frame members 22 connected between the upper and lower ends of the vertical frame members 21, and a pair of facing members 23 attached to both sides of a rectangular frame made up of the vertical frame members 21 and horizontal frame members 22. The thickness of the facing members 23 is set so that the reinforcing wall 10 achieves the target load-bearing capacity and rigidity. The vertical frame members 21 are shorter than the horizontal frame members 22. The wooden panel 20 may have auxiliary cross members 24 assembled to the frame on the inside of the frame. The vertical frame members 21, horizontal frame members 22, facing members 23, and auxiliary cross members 24 are made of wood. The wooden panel 20 may have insulation material filled on the inside of the frame. In the example shown in Figure 4, the auxiliary support members 24 are provided parallel to the vertical frame members 21. However, the auxiliary support members 24 may also be provided parallel to the horizontal frame members 22. In the example shown in Figure 4, the auxiliary support member 24 is positioned biased toward one of the vertical frame members 21, and the distance from one vertical frame member 21 to the auxiliary support member 24 is shorter than the distance from the other vertical frame member 21 to the auxiliary support member 24. However, the auxiliary support member 24 may also be positioned at the midpoint between one vertical frame member 21 and the other vertical frame member 21.

[0028] The wooden panels 20 are arranged horizontally, with the width of each panel being smaller than the height of each panel. The wooden panels 20 are stacked in a double layer in the out-of-plane direction to form a stack. The stacked wooden panels 20 may simply be touching each other, or they may be joined together with adhesive or screws. The stack may also consist of three or more layers of wooden panels 20 stacked in the out-of-plane direction. In other words, a stack is defined as two or more layers of wooden panels 20 stacked in the out-of-plane direction. The number of layers of wooden panels 20 is set so that the reinforcing wall 10 achieves the target load-bearing capacity, rigidity, and thickness.

[0029] Multiple stacks are arranged vertically without gaps between adjacent columns 2. Each stack has the same number of overlapping wooden panels 20. Vertically adjacent wooden panels 20 may be joined by adhesive or screws. In the example shown in Figure 3, there are 3 stacks, but the number of stacks may be 2 or 4 or more. The number of stacks is set so that the reinforcing wall 10 achieves the target load-bearing capacity, rigidity, and area. In the examples shown in Figures 4 and 5, the auxiliary bracing members 24 of each wood panel 20 are positioned at the same location in the lateral direction. However, the lateral position of the auxiliary bracing members 24 of at least one wood panel 20 may be offset laterally from the lateral position of the auxiliary bracing members 24 of the other wood panels 20. For example, as shown in Figure 6, the auxiliary bracing members 24 of vertically aligned wood panels 20 may be arranged alternately in the lateral direction. In this case, the auxiliary bracing members 24 of wood panels 20 that overlap out of plane may be arranged alternately in the lateral direction, or they may be positioned at the same location in the lateral direction. For example, as shown in Figure 7, the auxiliary bracing members 24 of wood panels 20 that overlap out of plane may be arranged alternately in the lateral direction. In this case, the auxiliary bracing members 24 of vertically aligned wood panels 20 may be arranged alternately in the lateral direction, or they may be positioned at the same location in the lateral direction.

[0030] The inner frame 30 is assembled in a rectangular frame shape. The inner frame 30 is positioned outside the stack arrangement. The inner circumference of the inner frame 30 is joined to the outer circumference of the stack arrangement by adhesive or screws. The inner frame 30 is equal to the total thickness of the stack. The inner frame 30 has a pair of vertical members 31 and a pair of horizontal members 32. The vertical members 31 and horizontal members 32 are square-bar-shaped pieces of wood. The two vertical members 31 are joined to the left and right ends of the stack arrangement, respectively. The two horizontal members 32 are joined to the top and bottom ends of the stack arrangement, respectively. The upper horizontal member 32 is connected between the top ends of the two vertical members 31. The lower horizontal member 32 is connected between the top ends of the two vertical members 31.

[0031] The outer frame 40 is assembled in a rectangular frame shape. The outer frame 40 encloses the inner frame 30 between adjacent columns 2. The outer frame 40 is joined to the columns 2 on both sides of the outer frame 40 by adhesive or screws. An L-shaped bracket 70 is placed in the inner corner formed by the outer frame 40 and the columns 2, and the bracket 70 is joined to the outer frame 40 and the columns 2 by screws or the like.

[0032] The inner circumference of the outer frame 40 is separated from the outer circumference of the inner frame 30, and a gap 90 exists between the inner circumference of the outer frame 40 and the outer circumference of the inner frame 30. The outer frame 40 is equal to the thickness of the stack, that is, the total thickness of the wooden panels 20 that make up the stack. The outer frame 40 has a thickness equal to the thickness of the inner frame 30. The outer frame 40 has a pair of vertical members 41 and a pair of horizontal members 42. The vertical members 41 and horizontal members 42 are rectangular wooden rods. The two vertical members 41 are joined to the two columns 2, respectively. The upper horizontal member 42 is connected between the upper ends of the two vertical members 41. The lower horizontal member 42 is connected between the upper ends of the two vertical members 41. Note that since many years have passed since the construction of the building 1, adjacent columns 2 may not be parallel. If adjacent columns 2 are not parallel, then the two vertical members 41 are also not parallel.

[0033] If the horizontal member 5 is installed between adjacent columns 2 above, below, or both above and below the outer frame 40, the outer frame 40 may be joined to the columns 2 on both sides of the outer frame 40 by adhesive or screws. Alternatively, the upper, lower, or upper and lower horizontal members 42 may be the horizontal member 5.

[0034] The front facing material 50 surrounds the arrangement of the stacks and is attached to the front surfaces of the outer frame 40 and inner frame 30 with screws or adhesive. The gap between the outer frame 40 and inner frame 30 is closed by the facing material 50 from the front surfaces of the outer frame 40 and inner frame 30. The facing material 50 consists of multiple structural plywood sheets arranged in a rectangular frame shape. Specifically, there are four structural plywood sheets, with the upper structural plywood attached to the front surfaces of the upper horizontal members 32 and 42, the lower structural plywood attached to the front surfaces of the lower horizontal members 32 and 42, the right structural plywood attached to the front surfaces of the right vertical members 31 and 41, and the left structural plywood attached to the front surfaces of the left vertical members 31 and 41. Gaps may exist between adjacent structural plywood sheets. The front surfaces of the outer frame 40 and inner frame 30 are also called the first visible surfaces.

[0035] The back panel 60 surrounds the arrangement of the stacks and is attached to the front of the outer frame 40 and inner frame 30 with screws or adhesive. The gap between the outer frame 40 and inner frame 30 is sealed from the back of the outer frame 40 and inner frame 30 by the panel 60. The panel 60 consists of multiple structural plywood sheets arranged in a rectangular frame shape. Specifically, there are four structural plywood sheets, with the upper structural plywood attached to the back of the upper horizontal members 32 and 42, the lower structural plywood attached to the back of the upper horizontal members 32 and 42, the right structural plywood attached to the back of the right vertical members 31 and 41, and the left structural plywood attached to the back of the left vertical members 31 and 41. Gaps may exist between adjacent structural plywood sheets. The back of the outer frame 40 and inner frame 30 is also called the second visible surface.

[0036] The total thickness of the facing materials 50, 60 and the outer frame 40 is greater than the thickness of the stack, that is, the total thickness of the wood panels 20 that make up the stack. However, the inner frame 30 and the outer frame 40 may have a thickness less than the thickness of the stack, and the total thickness of the facing materials 50, 60 and the outer frame 40 may be equal to the thickness of the stack.

[0037] In the above description, a single reinforcing wall 10 is installed between adjacent columns 2. In contrast, multiple reinforcing walls 10 may be installed between adjacent columns 2, and these reinforcing walls 10 may be arranged vertically with or without gaps between them.

[0038] The reinforcing wall 10, configured as described above, firmly supports the building 1 by receiving its load and seismic forces. The reinforcing wall 10 contributes to improving the seismic resistance of the building 1.

[0039] The reinforcing wall 10 is installed between adjacent columns 2, allowing the columns 2 to withstand in-plane seismic forces between them. The reinforcing wall 10 contributes to suppressing damage to the columns 2 caused by earthquakes, such as buckling, deformation, breakage, or cracking.

[0040] Since the wooden panels 20, which are manufactured in advance at the factory, are used for the reinforcing wall 10, the load-bearing capacity of the reinforcing wall 10 is high, and the construction period required for the installation of the reinforcing wall 10 is short.

[0041] Even if column 2 is warped or adjacent columns 2 are not parallel, a gap exists between the inner frame 30 and the outer frame 40, and this gap absorbs the warping and non-parallelism of column 2. This reinforcing wall 10 can be installed between adjacent columns 2 even if column 2 is warped or adjacent columns 2 are not parallel.

[0042] Because the reinforcing wall 10, particularly the outer frame 40, is joined to the column 2 in a vertically extended area, localized damage to the column 2 does not occur. However, if diagonal bracing were installed between adjacent columns 2 instead of the reinforcing wall 10, there is a risk of localized damage to the column 2 at the point where the diagonal bracing is joined to the column 2. This problem does not occur with the reinforcing wall 10.

[0043] Building 1 will be seismically reinforced by reinforcing wall 10. Building 1 is a valuable cultural property that was born, nurtured, and preserved throughout Japan's long history. Reinforcing wall 10 will contribute to achieving the SDGs (Sustainable Development Goals) through the protection of such cultural properties.

[0044] <3. Variant Example> (1) Figure 8 is a front view of the reinforcing wall 10A of the first modified example. Figure 9 is a vertical cross-sectional view along the line IX-IX shown in Figure 8. Figure 10 is a vertical cross-sectional view along the line XX shown in Figure 9. Figure 11 is a horizontal cross-sectional view along the line XI-XI shown in Figures 9 and 10.

[0045] The same reference numerals are used to denote the corresponding components between the modified reinforcement wall 10A and the reinforcement wall 10 described above. The following will mainly explain the differences between the modified reinforcement wall 10 and the modified reinforcement wall 10.

[0046] In the reinforced wall 10 described above, the wooden panels 20 are doubled in the out-of-plane direction, the stacks are arranged vertically without gaps inside the inner frame 30, and the outer periphery of the stack arrangement is joined to the inner periphery of the inner frame 30.

[0047] In contrast, in the reinforced wall 10A, the wooden panels 20 are not overlapped but form a single layer, the wooden panels 20 are arranged vertically without gaps, and the outer perimeter of the arrangement of wooden panels 20 is joined to the inner perimeter of the inner frame 30. The thickness of the wooden panels 20 in the reinforced wall 10A is equal to the thickness of the stack in the reinforced wall 10. However, the thickness of the wooden panels 20 in the reinforced wall 10A may be equal to the thickness of the wooden panels 20 in the reinforced wall 10.

[0048] In the reinforcing wall 10A, the inner frame 30 and the outer frame 40 have a thickness thinner than the thickness of the wood panel 20, and the total thickness of the facing materials 50, 60 and the outer frame 40 is equal to the thickness of the wood panel 20. However, the total thickness of the facing materials 50, 60 and the outer frame 40 may be thicker than the thickness of the wood panel 20.

[0049] Reinforcement wall 10A is identical to reinforcement wall 10, except as described above.

[0050] In this case, a single reinforcing wall 10A is installed between adjacent columns 2. Alternatively, multiple reinforcing walls 10A may be installed between adjacent columns 2, and these reinforcing walls 10A may be arranged vertically with or without gaps between them.

[0051] (2) Figure 12 is a front view of the reinforcing wall 10B of the second modified example. Figure 13 is a vertical cross-sectional view along the line XIII-XIII shown in Figure 12. Figure 14 is a vertical cross-sectional view along the line XIV-XIV shown in Figure 13. Figure 15 is a horizontal cross-sectional view along the line XV-XV shown in Figures 13 and 14.

[0052] The same reference numerals are used to denote the corresponding components between the modified reinforcement wall 10B and the reinforcement wall 10 described above. The differences between the modified reinforcement wall 10 and the modified reinforcement wall 10 will be explained below.

[0053] In the reinforced wall 10 described above, the wooden panels 20 are doubled in the out-of-plane direction, the stacks are arranged vertically without gaps, and the outer perimeter of the stack arrangement is joined to the inner perimeter of the inner frame 30.

[0054] In contrast, in the reinforced wall 10B, the wooden panels 20 are not overlapped but are single-layered, and the outer perimeter of a single wooden panel 20 is joined to the inner perimeter of the inner frame 30.

[0055] In the reinforced wall 10B, the inner frame 30 and the outer frame 40 have a thickness thinner than the thickness of the wood panel 20, and the total thickness of the facing materials 50, 60 and the outer frame 40 is equal to the thickness of the wood panel 20. However, the total thickness of the facing materials 50, 60 and the outer frame 40 may be thicker than the thickness of the wood panel 20.

[0056] Reinforcement wall 10B is identical to reinforcement wall 10, except as described above. In this case, a single reinforcing wall 10B is installed between adjacent columns 2. Alternatively, multiple reinforcing walls 10B may be installed between adjacent columns 2, and these reinforcing walls 10B may be arranged vertically with or without gaps between them.

[0057] In the reinforcing wall 10B, the wooden panels 20 were not overlapped and were in a single layer. In contrast, the wooden panels 20 may be overlapped in two or more layers in the out-of-plane direction to form a stack, and the outer perimeter of a single stack may be joined to the inner perimeter of the inner frame 30. In this case as well, a single reinforcing wall may be installed between adjacent columns 2, or multiple reinforcing walls arranged vertically may be installed between adjacent columns 2.

[0058] (3) Reinforcement walls 10, 10A, or 10B are installed between adjacent columns 2. Alternatively, reinforcement walls 10, 10A, or 10B may be installed between adjacent horizontal members 5. In this case, the two horizontal members 42 are joined to the upper and lower horizontal members 5, respectively.

[0059] (4) In the reinforced wall 10 described above, the wooden panels 20 are arranged horizontally, with the wooden panels 20 overlapping in a double layer in the out-of-plane direction, and such stacks are arranged vertically without gaps inside the inner frame 30, and the outer periphery of such stack arrangement is joined to the inner periphery of the inner frame 30. In contrast, the wooden panels 20 may be arranged vertically, with two or more layers of wooden panels 20 overlapping in the out-of-plane direction, and such stacks may be arranged horizontally without gaps inside the inner frame 30, with the outer perimeter of such stack arrangement being joined to the inner perimeter of the inner frame 30. Furthermore, the wooden panels 20 may be arranged horizontally or vertically, and the wooden panels 20 may be stacked in two or more layers in the out-of-plane direction, and such stacks may be arranged without gaps in the horizontal and vertical directions inside the inner frame 30, and the outer periphery of such stack arrangement may be joined to the inner periphery of the inner frame 30. Alternatively, the wooden panels 20 may be arranged horizontally, and the wooden panels 20 may be in a single layer without overlapping, and multiple wooden panels 20 may be arranged horizontally without gaps inside the inner frame 30, with the outer perimeter of the arrangement of wooden panels 20 being joined to the inner perimeter of the inner frame 30.
