Description

Technical Field

[0005] ,

[0001] The present invention relates to a joining structure of a wooden structural material and an outer wall member, an inner wall member or a floor member using a metal joining plate and a method for forming the same.

Background Art

[0002] Conventionally, outer wall members, inner wall members, and floor members have been joined to wooden structural materials such as columns, beams, walls, and floors to form structures such as houses. As these outer wall members, inner wall members, and floor members, cement processed materials such as mortar and concrete are used. The cement processed material is a building material that is used by adding water and the like to cement, which is a gray powdery material, and processing it. Although it is a fluid in its initial state, it solidifies over time. When the cement processed material is used as an outer wall member, an inner wall member, or a floor member, it cannot be firmly joined to the wooden structural material and may slip.

[0003] Therefore, coach bolts have been used to fix outer wall members, inner wall members, and floor members to wooden structural materials to prevent slipping. However, in this case, a plurality of coach bolts have to be attached, which is time-consuming and costly. In addition, the joining was not sufficient.

[0004] On the other hand, GANG-NAIL is used as a member that reliably joins wood to wood and forms a wooden truss excellent in durability, accuracy, and stability. GANG-NAIL is a wood fastening hardware (nail plate) born in the United States, and hot-dip galvanized steel plates, ordinary steel plates, etc. are used. For example, a plurality of wooden members are joined by a joining component provided with a needle function part and processed into a large cross-section wooden structural material. (See Patent Document 1.) In addition, it has also been proposed to join a plurality of wooden members with a steel member provided with a roughing part to form a wood-steel hybrid structure. (See Patent Document 2.)

[0005] Therefore, we conceived the idea that such joining components could be used to easily and firmly join exterior wall members, interior wall members, or floor members made of cement-processed materials to wooden structural materials. After considering various joining components, we completed the present invention. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]

[0021] (Embodiment 1) (Joining structure of exterior wall members to wooden structural materials) Figure 1 is a perspective view showing an example of a joint structure for an exterior wall member to a wooden structural member of a wall. Figure 2 is a cross-sectional view taken along line AA, showing another example of a joint structure for an exterior wall member to a wooden structural member of a wall. In Figures 1 and 2, the left side is the exterior and the right side is the interior.

[0022] (wooden structural material) As the wood structural material 10, a wall structural material consisting of four layers of CLT (Cross Laminated Timber) boards is used. The board material is, for example, a board-shaped member made of wood or laminated timber. Laminated timber includes oriented boards in which multiple roughly rectangular sawn boards (laminas) are joined together at their long sides. The board material is preferably an oriented board, and preferably laminated and bonded so that the orientation of the board material is perpendicular to each other. This further increases the strength. The thickness of the board material is preferably 1 cm or more and 3.6 cm or less. If it is less than 1 cm, sufficient strength cannot be obtained, and if it is more than 3.6 cm, it may become too bulky and difficult to handle. The board material is preferably flame-retardant treated wood. This further increases the fire resistance. Note that the wood structural material is not limited to CLT, but any material used as a facing material (for example, sawn timber laid and bonded together, OSB material, MDF material, etc.) is acceptable.

[0023] (Mounting load-bearing fastener) The wooden structural member 10 is fitted with a load-bearing fastener 23. This allows for easy installation and handling. The mounting load-receiving fasteners 23 are connected to the curtain wall support fasteners, which are installed on the structural side of the building, for example, to steel beams or columns, by means of locking, welding, bolting, etc., thereby constructing the curtain wall exterior.

[0024] (Cement processing materials) The exterior wall member 11 is made of a cement-processed material. The cement-processed material is preferably mortar or concrete. This improves weather resistance and enhances the appearance. Cement is a gray, powdery material; mortar is a material made by adding water and sand to cement; and concrete is a material made by adding water, sand, and gravel to cement. With consideration for flame retardancy and fire resistance, it is preferable to use, for example, fiber-reinforced mortar or mortar reinforced with reinforcing bars as the exterior wall member 11. This makes it possible to improve flame retardancy and fire resistance while ensuring durability. Here, it is desirable that the flame retardant or fire-resistant material conforms to Article 107 of the Building Standards Act Enforcement Order. Examples of fibers in fiber-reinforced mortar include glass fibers (GRC), carbon fibers (CFRC), polypropylene resin fibers, steel fibers (SFRC), and stainless steel fibers.

[0025] (Waterproof coating) Furthermore, the exterior wall component 11 is coated with a waterproofing agent. This improves its waterproofing performance. Waterproofing treatments can include the application of various water-repellent materials, asphalt waterproofing, sheet waterproofing, membrane waterproofing, and coatings such as acrylic resin, acrylic urethane resin, acrylic silicone resin, fluororesin, and inorganic paints. However, if sufficient waterproofing performance can be ensured by the cement-based material, waterproofing can be omitted.

[0026] (Interior materials) Interior finishing material 24 is attached to the inside of the wooden structural material.

[0027] (Metal joint plate) The exterior wall member 11 is joined to the wooden structural material 10 of the wall by a metal joining plate 12. Figure 4 is a plan view showing an example of a metal joint plate (first metal joint plate). Figure 5 is a front view showing an example of a metal joint plate. Figure 6 is a side view showing an example of a metal joint plate. Figure 7 is a side view showing an example of a claw portion of a metal joint plate. The metal joint plate 12 is used when joining an exterior wall member 11 made of cement-processed material to a wooden structural material 10, which is a wall or floor. The metal joint plate 12 fixes and integrates the exterior wall member 11 with the wooden structural material 10. This makes it easier to handle.

[0028] The metal joining plate 12 has a flat plate portion 20 and a plurality of claw portions 21 provided on the flat plate portion 20. Figure 4 In this example, a rectangular plate in plan view is provided with 24 claws arranged in a 6x4 grid, but the shape of the plate, the number of claws, and their arrangement are not limited to this. The claw portion 21 is plate-shaped, with a flat plate portion 20 cut out and provided raised on one of its surfaces, with the claw portion raised on one surface facing upward. (First claw portion) It is called a claw, and the claw portion raised on the other side is a downward claw portion (Second claw portion) It is called [name of opening]. The raised opening is referred to as opening 22. As shown in Figure 7, the plan view shape of the claw portion 21 has an arrow shape, with a rectangular portion 21b extending outward from the flat plate portion 20 side and a triangular portion 21a provided thereon. The two vertices on the base side of the triangular portion 21a protrude substantially perpendicular to the piercing direction, forming first protrusions 21c and 21d that make it difficult to pull out when pierced into the joint surface. The rectangular portion 21b is provided with second protrusions 21e and 21f that protrude substantially perpendicular to the piercing direction from the first protrusions 21c and 21d towards the flat plate portion 20 side, making it even more difficult to pull out when pierced into the joint surface. By providing protrusions at different positions in the piercing direction of the rectangular portion 21b, the first resistance surfaces 21h, 21i and the second resistance surfaces 21j, 21k (also called "returns"), which are difficult to pull out, are doubled in the piercing direction, thereby strengthening the joint. In particular, this structure with double barbs can create a strong bond even when piercing a material that is fluid in its initial state but solidifies over time. This allows for easy and strong bonding of exterior wall components made of cement-processed material to the wooden structural material of the wall, preventing the exterior wall components from peeling off. Furthermore, the number of protrusions provided at different positions in the piercing direction of the rectangular portion 21b only needs to be two or more; it may be three or four. If the protrusions are of the same shape, a larger number will result in a stronger joint.

[0029] In Figures 1 and 2, metal connecting plates 12 are attached in a grid pattern, including the vicinity of the four corners on the outer surface of the wooden structural material 10, to integrate the exterior wall member 11 and the wooden structural material 10. However, the number and placement of the metal connecting plates 12 are not limited to these figures.

[0030] Figure 3 is an enlarged cross-sectional view showing an example of a joining structure for exterior wall members to the wooden structural members of a wall. As shown in Figure 3, the joining structure of the exterior wall member to the wooden structural member is such that a plurality of claw portions 21 protruding from one side of the flat plate portion 20 are inserted into the joining surface 10a of the wooden structural member 10 to join the metal joining plate 12 to the wooden structural member 10, and a plurality of claw portions 21 protruding from the other side of the flat plate portion 20 are inserted into the joining surface 11a of the exterior wall member 11 to join the metal joining plate 12 to the exterior wall member 11.

[0031] In this embodiment, an example of a joining structure for an exterior wall member to a wooden structural material of a wall is shown, but it may also be a joining structure for an interior wall member to a wooden structural material of a wall.

[0032] (Embodiment 2) Figure 8 is a perspective view showing another example of a joining structure for exterior wall members to the wooden structural members of a wall. Aside from the decorative material 17 being attached to the outside, the structure is the same as that shown in Embodiment 1. Wood can be used as the material for the decorative material 17. This configuration can further improve the appearance. Furthermore, when integrating the decorative material 17 (wooden finishing material) with the exterior wall member 11 (surface wall material such as concrete) in Figure 8, the integration can also be done using the metal connecting plate 12 (gang nail). Furthermore, when using concrete as a core material (a material that bears structural loads) and attaching wood finishing material to the surface, metal connecting plates 12 (gang nails) can be used to fasten them together. Furthermore, when using concrete for structures such as eaves and attaching a wooden finishing material to the surface, metal connecting plates 12 (gang nails) can be used to set them in place before pouring the concrete.

[0033] (Embodiment 3) Figure 9 is a perspective view showing an example of a joint structure for floor members to wooden structural materials of a floor. Figure 10 is a cross-sectional view showing an example of a joint structure for floor members to wooden structural materials of a floor. CLT is used as the wooden structural material 30 for the floor, and a floor member 31 made of RC slab is formed on its upper surface. The floor member 31 is made of cement-processed material. Multiple reinforcing bars 33 are laid inside the floor member 31. The reinforcing bars 33 include bars that extend from back to front and horizontal bars that extend from left to right. Multiple of each are arranged at regular intervals, forming a grid-like arrangement in plan view. The joining structure of the floor member to the wooden structural material of the floor is such that a plurality of claw portions 21 protruding from one side of the flat plate portion 20 are inserted into the joining surface 10a of the wooden structural material 30 of the floor, thereby joining the metal joining plate 12 to the wooden structural material 30, and a plurality of claw portions 21 protruding from the other side of the flat plate portion 20 are inserted into the joining surface 31a of the floor member 31, thereby joining the metal joining plate 12 to the floor member 31. This allows for fixed and integrated construction, increasing rigidity and preventing the floor members from shifting away from the wooden structural materials of the floor. The floor member 31 is fixed to the main beam 36 with headed studs 38, and the wooden structural member 30 of the floor is fixed with CLT support angles 37. The CLT is also fixed to the secondary beam 35 with headed studs 38. Note that the wooden structural member 30 does not have to be CLT; any material used as a surface material (for example, lumber that has been laid and glued together, OSB material, MDF material, etc.) is acceptable.

[0034] (Embodiment 4) Figure 11 is a perspective view showing an example of a joint structure for floor members to a wooden structural floor. Figure 12 is a cross-sectional view showing an example of a joint structure for floor members to a wooden structural floor. CLT is used as the wooden structural material 40 for the floor, and a floor member 41 made of RC slab is formed on its upper surface. The floor member 41 is made of cement-processed material. Multiple reinforcing wires 43 are stretched throughout the interior of the floor member 41. The reinforcing wires 43 consist of wires extending from back to front and horizontal wires extending from left to right. Multiple wires of each type are arranged at regular intervals, forming a grid-like arrangement in plan view. The joint structure of the floor member to the wooden structural member of the floor is such that a plurality of claw portions 21 protruding from one side of the flat plate portion 20 are inserted into the joint surface 40a of the wooden structural member 40 of the floor, thereby joining the metal joint plate 12 to the wooden structural member 40, and a plurality of claw portions 21 protruding from the other side of the flat plate portion 20 are inserted into the joint surface 41a of the floor member 41, thereby joining the metal joint plate 12 to the floor member 41. This allows for rigid integration and prevents the floor members from shifting away from the wooden structural material of the floor. Furthermore, the wooden structural member 40 of the floor does not have to be CLT; any material used as a surface material (such as plywood) is acceptable, and the wooden structural member 40 is held and fixed by multiple sawn timbers or laminated timbers 45. In addition, the floor member 41 is held and fixed on top of the wooden structural member 40 of the floor.

[0035] (Embodiment 5) Figure 13 is a perspective view showing another example of a metal joint plate (second metal joint plate). Figure 14 is a plan view showing another example of a metal joint plate. Figure 15 is a front view showing another example of a metal joint plate. The metal joining plate 52 has a flat plate portion 60 and a plurality of claw portions 21 provided on the flat plate portion 60. In Figures 13 and 14, the claw portions 21 are provided radially on a circular plate in plan view, offset at equal intervals from the center. The first row is located near the center. (inner ring) Then, the claw portion 21 is formed in the second stage at a distant position, the first stage is formed in eight equally spaced directions, and the second stage (inner ring) teeth Evenly spaced directionThey are formed in such a way that adjacent ones protrude in opposite directions. However, the shape of the plates, the number of claws, and their arrangement are not limited to these.

[0036] The claw portion 21 is plate-shaped, with a flat plate portion 60 cut out and positioned to rise on one of its surfaces. The raised opening portion is called the opening 22. As shown in Figure 7, the plan view shape of the claw portion 21 has an arrow shape, with a rectangular portion 21b extending outward from the flat plate portion side and a triangular portion 21a provided thereon. The two vertices on the base side of the triangular portion 21a protrude substantially perpendicular to the piercing direction, forming first protrusions 21c and 21d that make it difficult to pull out when pierced into the joint surface. In addition, the rectangular portion 21b is provided with second protrusions 21e and 21f that protrude substantially perpendicular to the piercing direction from the first protrusions 21c and 21d towards the flat plate portion 20, making it even more difficult to pull out when pierced into the joint surface. By providing protrusions at different positions in the piercing direction of the rectangular portion 21b, the first resistance surfaces 21h, 21i and the second resistance surfaces 21j, 21k (also called "returns"), which are difficult to pull out, are doubled in the piercing direction, thereby strengthening the joint. In particular, this structure with double barbs can create a strong bond even when piercing a material that is fluid in its initial state but solidifies over time. This allows for easy and strong bonding of exterior wall members made of cement-processed material to wooden structural materials, preventing the exterior wall members from peeling off and the floor members from shifting away from the wooden structural materials of the floor. Furthermore, the number of protrusions provided at different positions in the piercing direction of the rectangular portion 21b only needs to be two or more; it may be three or four. If the protrusions are of the same shape, a larger number will result in a stronger joint.

[0037] (Embodiment 6) Figure 16 is a perspective view showing yet another example of a metal joint plate (third metal joint plate). Figure 17 is a plan view showing yet another example of a metal joint plate. Figure 18 is a front view showing yet another example of a metal joint plate. Figure 19 is a side view showing yet another example of a metal joint plate. The metal joining plate 72 has a flat plate portion 80 and a plurality of claw portions 21, 81 provided on the flat plate portion 80. The plate, which is rectangular in plan view, has four vertical and three horizontal rows of claw portions 21, and two vertical and four horizontal rows of claw portions 81. The four horizontal rows of claw portions 81 sandwich the three horizontal rows of claw portions 21 in the vertical direction. The two vertical rows of claw portions 81 are positioned horizontally between the first and second rows and between the third and fourth rows of the four vertical rows of claw portions 21 from the left. However, the shape of the plate, the number of claw portions, and their arrangement are not limited to this.

[0038] (delete)

[0039] Furthermore, the claw portion 81 is also plate-shaped, with a notch cut into the flat plate portion 80, and is provided rising on one side. However, the rectangular portion 81b of the claw portion 81 is bent in a V-shape when viewed from the side at the bent portion 81g. With this structure, when the claw portion 21 on one side of the flat plate portion 80 is thrust into a wooden structural material, the claw portion 81 is pushed out to the other side of the flat plate portion 80, making it possible to thrust it into an exterior wall member or floor member. When the claw portion 21 is thrust in, it is pressed by the joining surface and the triangular portion 81a protrudes on the other side, so it is a protruding claw portion and a downward-facing claw portion. (Second claw portion) The raised opening is designated as the opening 82. This configuration ensures that the protruding claw portion does not protrude to the other side unless the claw portion 21 is pierced, thus making it easy to handle by only paying attention to one side. The plan view shape of the claw portion 81 has an arrow shape, with a triangular portion 81a provided on a connecting portion 81b extending outward from the flat plate portion side. The two vertices on the base side of the triangular portion 21a protrude substantially perpendicular to the piercing direction, forming first protrusions 81c and 81d that make it difficult to pull out when pierced into the joint surface. The rectangular portion 81b is provided with second protrusions 81e and 81f that protrude substantially perpendicular to the piercing direction from the first protrusions 81c and 81d towards the flat plate portion 80, making it even more difficult to pull out when pierced into the joint surface. By providing protrusions at different positions in the piercing direction of the rectangular portion 81b, the first resistance surfaces 81h, 81i and the second resistance surfaces 81j, 81k (also called "returns"), which are difficult to pull out, are doubled in the piercing direction, thereby strengthening the joint. In particular, this structure with double barbs can create a strong bond even when piercing a material that is fluid in its initial state but solidifies over time. This allows for easy and strong bonding of exterior wall members made of cement-processed material to wooden structural materials, preventing the exterior wall members from peeling off and the floor members from shifting away from the wooden structural materials of the floor. Furthermore, the number of protrusions provided at different positions in the piercing direction of the rectangular portion 81b does not need to be more than two; it may be three or four. If the protrusions are of the same shape, a larger number will result in a stronger joint.

[0040] (Embodiment 7) Figure 20 is a perspective view showing yet another example of a metal joint plate (a fourth metal joint plate). Figure 21 is a front view showing yet another example of a metal joint plate. Figure 22 is a left side view showing yet another example of a metal joint plate. The metal joint plate 92 has a flat plate portion 100 and a plurality of claw portions 21, 101 provided on the flat plate portion 100. The plate, which is rectangular in plan view, has four vertical and four horizontal rows of claw portions 21 and two claw portions 101 on each side. The rightmost column of claw portions 21 is oriented in the direction of an arrow pointing from right to left, and the column to its left repeats the direction of an arrow pointing from top to bottom and bottom to top. Furthermore, this pattern is repeated in the column to its left and the column to its left. However, the shape of the plate, the number of claws, and their arrangement are not limited to these.

[0041] The claw portion 21 is plate-shaped, with a notch cut into the flat plate portion 100, and is provided with one side raised. The raised opening portion is called the opening 22. As shown in Figure 7, the plan view shape of the claw portion 21 has an arrow shape, with a rectangular portion 21b extending outward from the flat plate portion side and a triangular portion 21a at its tip. The two vertices on the base side of the triangular portion 21a protrude substantially perpendicular to the piercing direction, forming first protrusions 21c and 21d that make it difficult to pull out when pierced into the joint surface. The rectangular portion 21b is provided with second protrusions 21e and 21f that protrude substantially perpendicular to the piercing direction from the first protrusions 21c and 21d towards the flat plate portion 20, making it even more difficult to pull out when pierced into the joint surface. By providing protrusions at different positions in the piercing direction of the rectangular portion 21b, the first resistance surfaces 21h, 21i and the second resistance surfaces 21j, 21k (also called "returns"), which are difficult to pull out, are doubled in the piercing direction, thereby strengthening the joint. In particular, this structure with double barbs can create a strong bond even when piercing a material that is fluid in its initial state but solidifies over time.

[0042] Furthermore, the claw portion 101 is plate-shaped and has a wave-shaped claw portion 101a with multiple roughly triangular tip portions arranged horizontally in a plan view, and a rectangular portion 101b connecting the wave-shaped claw portion 101a and the flat plate portion 100. The rectangular portion 101b is provided with a bent portion 101g that is angled in a side view, and when the bent portion 101g is struck from the bending direction, the wave-shaped claw portion 101a protrudes from the other side of the flat plate portion 100, making it a hammering claw portion, and a downward-facing claw portion. (Second claw portion) This structure allows the corrugated claw portion 101a to protrude from the other side of the flat plate portion 100 when the bent portion 101g is struck, enabling it to be pierced into the exterior wall member or floor member. With this configuration, the corrugated claw portion 101a does not protrude from the other side unless the bent portion 101g is struck, so handling only requires attention to one side, making it easy to use. This allows for easy and strong bonding of exterior wall members made of cement-processed material to wooden structural materials, preventing the exterior wall members from peeling off and the floor members from shifting away from the wooden structural materials of the floor.

[0043] Furthermore, the claw portion 101 is provided on the side. This allows the claw portion 101 to be driven in without the claw portion 21 getting in the way.

[0044] (Embodiment 8) Figure 23 is a perspective view showing yet another example of a metal joint plate (the fifth metal joint plate). Figure 24 is a front view showing yet another example of a metal joint plate. Figure 25 is a left side view showing yet another example of a metal joint plate. The metal bonding plate 112 has a flat plate portion 120 and a plurality of claw portions 21, 121 provided on the flat plate portion 120. The configuration is the same as the fourth metal bonding plate, except that the pattern of the direction of the arrows on the claw portions 21 is different and the number of claw portions 121 provided on each side is 4. The claw portions 121 have the same configuration as the claw portions 101.

[0045] The claw portion 21 is plate-shaped, with a flat plate portion 120 cut out and raised on one side. The raised opening portion is called the opening 22. As shown in Figure 7, the plan view shape of the claw portion 21 has an arrow shape, with a rectangular portion 21b extending outward from the flat plate portion side and a triangular portion 21a at its tip. The two vertices on the base side of the triangular portion 21a protrude substantially perpendicular to the piercing direction, forming first protrusions 21c and 21d that make it difficult to pull out when pierced into the joint surface. The rectangular portion 21b is provided with second protrusions 21e and 21f that protrude substantially perpendicular to the piercing direction from the first protrusions 21c and 21d towards the flat plate portion 20, making it even more difficult to pull out when pierced into the joint surface. By providing protrusions at different positions in the piercing direction of the rectangular portion 21b, the first resistance surfaces 21h, 21i and the second resistance surfaces 21j, 21k (also called "returns"), which are difficult to pull out, are doubled in the piercing direction, thereby strengthening the joint. In particular, this structure with double barbs can create a strong bond even when piercing a material that is fluid in its initial state but solidifies over time.

[0046] Furthermore, the claw portion 121 is plate-shaped and has a wave-shaped claw portion 121a with multiple roughly triangular tip portions arranged horizontally in a plan view, and a rectangular portion 121b connecting the wave-shaped claw portion 121a and the flat plate portion 120. The rectangular portion 121b is provided with a bent portion 121g that is angled in a side view, and when the bent portion 121g is struck from the bending direction, the wave-shaped claw portion 121a protrudes from the other side of the flat plate portion 120, making it a hammering claw portion, and a downward-facing claw portion. (Second claw portion) This structure allows the corrugated claw portion 121a to protrude from the other side of the flat plate portion 120 when the bent portion 121g is struck, enabling it to be pierced into the exterior wall member or floor member. With this configuration, the corrugated claw portion 121a does not protrude from the other side unless the bent portion 121g is struck, so handling only requires attention to one side, making it easy to use. This allows for easy and strong bonding of exterior wall members made of cement-processed material to wooden structural materials, preventing the exterior wall members from peeling off and the floor members from shifting away from the wooden structural materials of the floor.

[0047] The claw portion 121 is located on the side. This allows the claw portion 121 to be driven in without the claw portion 21 getting in the way.

[0048] (Reference form 1) Figure 28 is a diagram showing Reference Embodiment 1, which illustrates an example in which the metal bonding plate of the present invention is used in a bonding structure different from the bonding structure of the present invention. First, two metal connecting plates 12 are placed spaced apart on one side of a single beam (wooden) 130. Next, another beam (wooden piece) 130 is placed on top of the aforementioned surface. Next, two beams (wooden pieces) are fastened together with stopper bolts to create a double beam. This structure can achieve greater stability of the overlapping beams than when the metal joint plate 12 is not used, and the metal joint plate of the present invention can be effectively used even in beam (wood) to beam (wood) joining structures. [Examples]

[0049] (Examples 1-7, Comparative Example 1) Metal joint plates according to Examples 1 to 7 shown in Table 1 were formed, and coach bolts according to Comparative Example 1 were prepared. Next, a joint structure was formed using test timber structural materials and exterior wall members. Next, accelerated durability tests were conducted on each joint structure to evaluate its structural stability based on whether or not delamination occurred. The joint structures using metal joint plates in Examples 1 to 7 showed high structural stability, with no delamination occurring compared to the comparative example using coach bolts. Figure 26 is a photograph showing an example of a metal joint plate (the sixth metal joint plate), and Figure 27 is a photograph showing another example of a metal joint plate (the seventh metal joint plate).
