Description

【Technical Field】 , , , 【0003】 , , , , , 【0001】 The present invention relates to a wood connection structure and a connector for connecting one piece of wood to another. 【Background Art】 777> 【0002】 Conventionally, many wood connection structures for connecting one piece of wood to another have been proposed. For example, a structure for connecting CLT boards (cross-laminated timber boards) so as to intersect is known (see Patent Document 1). In this wood connection structure, notch portions are formed in both pieces of wood, the notch portions are fitted to each other and integrated, and the surfaces of both pieces of wood are connected by a metal connecting member, thereby connecting both pieces of wood. Similarly, in a structure in which notch portions of two pieces of wood are fitted and integrated, as shown in FIG. 25, a wood connection structure for connecting a lower CLT board 2 and an upper CLT board 3 with a first connecting hardware 7 and two drift pins 9 is known. In this wood connection structure, storage recesses 22 and storage recesses 32 (the storage recesses 32 are not shown), pin insertion holes 24 and pin insertion holes 34 are formed in the lower CLT board 2 and the upper CLT board 3, respectively. The first connecting hardware 7 has a cylindrical shape, and two pairs of opposing pin holes 71b3 formed along a straight line orthogonal to the central axis of the cylinder are formed vertically. The first connecting hardware 7 is stored in the storage recess 22 of the lower CLT board 2 and the storage recess 32 of the upper CLT board 3 such that the pin holes 71b3 and the pin insertion holes 24, and the pin holes 71b3 and the pin insertion holes 34 overlap. The lower CLT board 2 and the upper CLT board 3 are connected by inserting drift pins 9 into the overlapping pin holes 71b3 and pin insertion holes 24, and the pin holes 71b3 and pin insertion holes 34, respectively. Note that FIG. 25(a) shows the case where the lower CLT board 2 and the upper CLT board 3 intersect at 45°, and FIG. 25(b) shows the case where the lower CLT board 2 and the upper CLT board 3 are orthogonal to each other. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Publication No. 2024-114515 [Overview of the Initiative] [Problems that the invention aims to solve] 【0004】 In the conventional wood joint structure shown in Patent Document 1 and Figure 25, if the angles at which the two pieces of wood intersect are different, it is necessary to prepare a connecting fitting that corresponds to that angle. That is, in the connecting fitting shown in Patent Document 1, it is necessary to prepare a fitting whose angle of contact between the two plates is the same as the angle at which the two pieces of wood intersect. Also, in the wood joint structure shown in Figures 25(a) and (b), the first connecting fitting 7 needs to be formed such that the two sets of pin holes 71b3 intersect at a 45° angle, and the two sets of pin holes 71b3 are perpendicular to each other. 【0005】 The angle at which two pieces of wood intersect is designed to vary depending on aesthetics and other factors. However, this requires preparing connecting hardware for each angle, which reduces the versatility of the connecting hardware and leads to increased costs. 【0006】 Therefore, the present invention aims to solve the above problems and provide a wood joint structure and connector that can connect two pieces of wood using one type of connecting hardware, even if the angles at which the two pieces of wood intersect are different.

In this Embodiment 1, CLT boards (Cross Laminated Timber) are used as the wood, and a structure in which two CLT boards are arranged perpendicularly and joined together will be described. Furthermore, the wood used is not limited to CLT boards; any other type of wood (not limited to laminated timber) may be used. Also, the wood is not limited to boards; it may be in other shapes such as rods or blocks. Moreover, the arrangement of the two pieces of wood is not limited to perpendicular; they may intersect at any other angle. Furthermore, the wood may be used for any purpose, such as structural or decorative materials. For the sake of explanation, we will use terms that indicate direction, such as up, down, and side, but the direction in which gravity acts is down, and the opposite direction is up. 【0012】 [Overall structure] Figure 1 shows a wooden joint structure 1 of Embodiment 1 of the present invention, where (a) is a view from above and (b) is a view from the side. The wood connecting structure 1 of this embodiment 1 is a structure for connecting a lower CLT board 2 and an upper CLT board 3 (one piece of wood and another piece of wood), and is a structure for connecting an upright upper CLT board 3 on top of an upright lower CLT board 2 so that the lower CLT board 2 and the upper CLT board 3 are perpendicular to each other. In this embodiment 1, two wooden joint structures 1 are used. The lower CLT panel 2 and the upper CLT panel 3 are rectangular panels of the same thickness. 【0013】 A triangular prism-shaped notch 21 is formed at the upper part of the lower CLT plate 2 where it intersects with the upper CLT plate 3. The triangle at the base of this triangular prism is a right-angled isosceles triangle obtained by bisecting the square-shaped portion where the lower CLT plate 2 and the upper CLT plate 3 intersect (hereinafter referred to as the intersection) with one of its diagonals. Similarly, a triangular prism-shaped notch 31 is formed at the lower part of the upper CLT panel 3 where it intersects with the lower CLT panel 2. The notches 21 and 31 are positioned to complement each other at the intersection of the lower CLT plate 2 and the upper CLT plate 3, with the remaining portion of the upper CLT plate 3 at the intersection fitting into notch 21, and the remaining portion of the lower CLT plate 2 at the intersection fitting into notch 31 (see also Figure 7). Furthermore, the lower end surface of the notch 21 abuts against the lower end surface of the upper CLT plate 3, and the upper end surface of the notch 31 abuts against the upper end surface of the lower CLT plate 2, thereby enabling the lower CLT plate 2 to support the weight of the upper CLT plate 3. 【0014】 In this embodiment 1, the notches 21 and 31 are formed in the shape of right-angled isosceles triangles obtained by bisecting the intersection of the square shape with one of its diagonals. However, the embodiment is not limited to this, and the notches can also be formed from two opposing right-angled isosceles triangles obtained by dividing the intersection of the square shape with two diagonals. Furthermore, the notches may be formed in any other shape, taking into consideration the shape of the intersection. 【0015】 One wooden joint structure 1 has a first connecting fitting 4, a second connecting fitting 5, and a drift pin 6. In this embodiment 1, one first connecting fitting 4 is positioned on the underside of the lower end surface of the notch 21 of the lower CLT plate 2, one second connecting fitting 5 is positioned on the underside of the upper end surface of the remaining portion of the intersection of the lower CLT plate 2 other than the notch 21 (however, the second connecting member 51, which will be described later, protrudes from the upper end surface), one first connecting fitting 4 is positioned on the upper side of the upper end surface of the notch 31 of the upper CLT plate 3, and one second connecting fitting 5 is positioned on the upper side of the lower end surface of the remaining portion of the intersection of the upper CLT plate 3 other than the notch 31 (however, the second connecting member 51, which will be described later, protrudes from the lower end surface) (see also Figure 7). Then, the first connecting hardware 4 of the lower CLT plate 2 and the second connecting hardware 5 of the upper CLT plate 3 are connected, and the second connecting hardware 5 of the lower CLT plate 2 and the first connecting hardware 4 of the upper CLT plate 3 are connected, thereby connecting the lower CLT plate 2 and the upper CLT plate 3. 【0016】 [First connecting hardware] Figure 2 shows the components of the first connecting hardware 4 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the first insertion member 42 and (b) shows the first connecting member 41. The upper left of (b) is a front view and the lower left is a bottom view. Figure 3 shows the first connecting hardware 4 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the structure before assembly and (b) shows the structure after assembly. The first connecting fitting 4 has a first connecting member 41 and a first insertion member 42. The first connecting member 41 is formed in a bottomed cylindrical shape and has a first bottom portion 41a and a first cylindrical portion 41b. The first bottom portion 41a has a first insertion member fixing hole 41a1 through which the first insertion member 42 is inserted and fixed. The first cylindrical portion 41b has two pin holes 41b3 formed on the cylinder, opposite each other along a straight line 41b2 that is twisted to the central axis 41b1 of the first cylindrical portion 41b, through which the drift pin 6 is inserted. These two pin holes 41b3 form a pair. In this embodiment 1, the two pin holes 41b3 are formed to be continuous by a groove 41b4 formed on the inner circumference of the first cylindrical portion 41b. The inner diameter of the pin holes 41b3 is formed to be approximately the same as the outer diameter of the drift pin 6, which will be described later. Furthermore, in this embodiment 1, two sets of pin holes 41b3 are formed symmetrically with respect to the central axis 41b1 of the first cylindrical portion 41b. The first insertion member 42 is formed in a rod shape, with male threads 42a formed on the circumferential surface except for both ends, and female threads 42b formed on one end. 【0017】 As shown in Figure 3(a), the first connecting member 41 and the first insertion member 42 are assembled using a socket head cap screw 43. More specifically, the first insertion member 42 is assembled by bringing one end of the first connecting member 41, on which a female thread 42b is formed, into contact with the first bottom 41a of the first connecting member 41 from the outside, so as to cover the first insertion member fixing hole 41a1 of the first bottom 41a of the first connecting member 41, inserting the socket head cap screw 43 into the first insertion member fixing hole 41a1 from the opening 41c of the first connecting member 41, and fastening the female thread 42b with the male thread of the socket head cap screw 43. In this embodiment 1, the first connecting member 41 and the first insertion member 42 are fixed by fastening the female thread 42b with the socket head cap screw 43, but other known mounting means may also be used, for example, by fastening a male thread formed on the end of the first insertion member 42 with a nut, as described in Embodiment 2 later. As shown in Figure 3(b), the first insertion member 42 is attached to the first bottom portion 41a of the first connecting member 41, extending away from the first connecting member 41 on the central axis 41b1 of the first cylindrical portion 41b. 【0018】 [Second connecting hardware] Figure 4 shows the components of the second connecting hardware 5 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the second connecting member 51 and (b) shows the second insertion member 52. The upper left of (a) is a top view, and the lower left is a front view. Figure 5 shows the second connecting hardware 5 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the structure before assembly and (b) shows the structure after assembly. The second connecting fitting 5 has a second connecting member 51 and a second insertion member 52. The second connecting member 51 is formed in a bottomed cylindrical shape and has a second bottom portion 51a and a second cylindrical portion 51b. The second bottom portion 51a has a second insertion member fixing hole 51a1 through which the second insertion member 52 is inserted and fixed. The second cylindrical portion 51b has a groove 51b3 extending circumferentially around its outer surface. The depth of the groove 51b3 is formed to be approximately the same as the outer diameter of the drift pin 6, which will be described later. The second insertion member 52 is the same type of member as the first insertion member 42, and is formed in a rod shape. Male threads 52a are formed on the circumferential surface except for both ends, and female threads 52b are formed on one end. 【0019】 As shown in Figure 5(a), the second connecting member 51 and the second insertion member 52 are assembled using socket head cap screws 53, similar to the first connecting member 41 and the first insertion member 42. More specifically, the second insertion member 52 is assembled by bringing one end of the second connecting member 51, where the female thread 52b is formed, into contact with the second bottom 51a from the outside so as to cover the second insertion member fixing hole 51a1 in the second bottom 51a of the second connecting member 51, inserting the socket head cap screw 53 into the second insertion member fixing hole 51a1 from the opening 51c of the second connecting member 51, and fastening the female thread 52b with the male thread of the socket head cap screw 53. In this embodiment 1, the second connecting member 51 and the second insertion member 52 are fixed by fastening the female thread 52b with the socket head cap screw 53, but other known mounting means may also be used, for example, by fastening a male thread formed on the end of the second insertion member 52 with a nut, as described in Embodiment 2 later. As shown in Figure 5(b), the second insertion member 52 is attached to the second bottom portion 51a of the second connecting member 51, similar to the first insertion member 42, on the central axis 51b1 of the second cylindrical portion 51b, extending in a direction away from the second connecting member 51. 【0020】 [Drift Pin] Figure 6 shows a drift pin 6 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) is before assembly and (b) is after assembly. In this first embodiment, a drift pin with a nut is used as the drift pin 6, and it has a drift pin body 61 and a nut 62. The drift pin body 61 has a tapered portion 61a at one end and a male thread 61b at the other end. The drift pin 6 is assembled by fastening a nut 62 to the male screw 61b of the drift pin body 61. 【0021】 [Wood connection structure] Figure 7 shows the wooden joint structure 1 of Embodiment 1 of the present invention before it is connected. Figure 8 shows the connection process of the first connecting hardware 4 and the second connecting hardware 5 used in the wood joint structure 1 of Embodiment 1 of the present invention, and the connection of the first connecting hardware 4 and the second connecting hardware 5 proceeds in the order from (a) to (e). As described above, two sets of wooden connecting structures 1 are used to connect an upright upper CLT board 3 to the upper side of an upright lower CLT board 2, so that the lower CLT board 2 and the upper CLT board 3 are perpendicular to each other. A storage recess 22 for housing the first connecting member 41 is formed on the lower end surface of the notch 21 of the lower CLT plate 2. A first insertion hole 231 is formed, drilled downward from the bottom surface of the storage recess 22, into which the first connecting hardware 4 is screwed. Furthermore, two pin insertion holes 24 for inserting drift pins 6 are formed on the side surface of the lower CLT plate 2 corresponding to the location where the storage recess 22 is formed (see enlarged view in Figure 7(a)). The pin insertion holes 24 are drilled from one side surface and are formed so as not to penetrate to the other side surface. A second insertion hole 332 is formed on the lower end surface of the remaining portion of the upper CLT plate 3, excluding the notch 31, and is drilled upwards into which the second connecting hardware 5 is screwed. 【0022】 The male screw 42a of the first connecting hardware 4 is screwed into the first insertion hole 231 of the lower CLT plate 2, and the first connecting member 41 is housed in the storage recess 22. In addition, the male screw 52a of the second connecting hardware 5 is screwed into the second insertion hole 332 of the upper CLT plate 3, and the second connecting member 51 is projected onto the lower end surface of the upper CLT plate 3. In this way, the first connecting hardware 4 is attached to the lower CLT board 2 and the second connecting hardware 5 is attached to the upper CLT board 3, forming a single wooden connecting structure 1. Similarly, the first connecting hardware 4 is attached to the upper CLT board 3, and the second connecting hardware 5 is attached to the lower CLT board 2, forming another timber connecting structure 1. In this embodiment 1, since the pin insertion hole 24 does not penetrate to the other side surface, the appearance of the other side surface can be improved. Also, although the drift pin 6 is not inserted to the other side surface and therefore difficult to remove, in this embodiment 1 a drift pin with a nut is used and the nut portion protrudes from the CLT plate, so when removing the drift pin 6, the protruding nut portion can be used to easily remove it. 【0023】 The lower CLT plate 2 and the upper CLT plate 3 are connected, with the first connecting fitting 4 and the second connecting fitting 5 attached to them respectively. The remaining portion of the upper CLT plate 3, excluding the notch 31 at the intersection, fits into the notch 21 of the lower CLT plate 2, and the remaining portion of the lower CLT plate 2, excluding the notch 21 at the intersection, fits into the notch 31 of the upper CLT plate 3. The first connecting fitting 4 of the lower CLT plate 2 and the second connecting fitting 5 of the upper CLT plate 3 are connected, and the second connecting fitting 5 of the lower CLT plate 2 and the first connecting fitting 4 of the upper CLT plate 3 are connected, thus connecting the lower CLT plate 2 and the upper CLT plate 3. 【0024】 In the following description, we will focus on the wood joint structure 1 that connects the second connecting hardware 5 of the lower CLT board 2 to the first connecting hardware 4 of the upper CLT board 3, omitting the lower CLT board 2 and the upper CLT board 3, and instead describe the connection between the first connecting hardware 4 and the second connecting hardware 5. As shown in Figure 8(a), the first connecting hardware 4 attached to the upper CLT panel 3 and the second connecting hardware 5 attached to the lower CLT panel 2 are arranged vertically. (This corresponds to the state shown in Figure 7.) In this state, the positions of the two pin holes 41b3 of the first connecting member 41 align with the positions of the pin insertion holes 34 of the upper CLT plate 3 (see enlarged view in Figure 7(b)). To attach the first connecting hardware 4 to the upper CLT plate 3, first, the male screw 42a of the first insertion member 42 of the first connecting hardware 4 is screwed into the first insertion hole 331 of the upper CLT plate 3, with the end opposite to the end where the female screw 42b is formed being screwed in first. Once the male screw 42a is screwed into the first insertion hole 331, the first bottom 41a of the first connecting member 41 is brought into contact with the end of the first insertion member 42, and the hex socket head bolt 43 is fastened to the female screw 42b to fix the first connecting member 41 and the first insertion member 42. When fixing the first connecting member 41, it is stored in the storage recess 22. However, if a drift pin 6 is inserted through the pin insertion hole 34 of the upper CLT plate 3 and the pin hole 41b3 of the first connecting hardware 4 prior to fixing, the first connecting member 41 and the first insertion member 42 can be fixed together while maintaining the alignment of the pin insertion hole 34 and the pin hole 41b3 without the first connecting member 41 rotating when the hex socket head bolt 43 is fastened. Furthermore, to attach the second connecting fitting 5 to the lower CLT plate 2, first, the male screw 52a of the second insertion member 52 of the second connecting fitting 5 is screwed into the second insertion hole 232 of the lower CLT plate 2, with the end opposite to the end where the female screw 52b is formed being screwed in first. Once the male screw 52a is screwed into the second insertion hole 232, the second bottom 51a of the second connecting member 51 is brought into contact with the end of the second insertion member 52, and the hex socket head bolt 53 is fastened to the female screw 52b to fix the second connecting member 51 and the second insertion member 52. Note that in the second connecting fitting 5, the groove 51b3 is formed all the way around, so there is no need to pay attention to the rotational position of the second connecting member 51. 【0025】 Next, as shown in Figures 8(b) and 8(c), the first connecting member 41 of the first connecting fitting 4 is fitted onto the second connecting member 51 of the second connecting fitting 5. At this time, the drift pin 6 that was inserted when fixing the first connecting member 41 and the first insertion member 42 is removed. When the first connecting member 41 is fitted onto the second connecting member 51, a space is formed through which the drift pin 6 can be inserted by the groove 41b4 on the inner circumferential surface of the first cylindrical portion 41b of the first connecting member 41 and the groove 51b3 of the second connecting member 51. As shown in Figure 8(d), once the first connecting member 41 is fitted onto the second connecting member 51, the drift pin 6 is inserted through the pin hole 41b3 and the space formed by the groove 41b4 on the inner circumferential surface of the first cylindrical portion 41b and the groove 51b3 of the second connecting member 51. In practice, the drift pin 6 is inserted through the pin insertion hole 34 of the upper CLT plate 3. As shown in Figure 8(e), inserting the drift pin 6 completes the connection between the lower CLT plate 2 and the upper CLT plate 3. 【0026】 In this embodiment 1, two wooden connecting structures 1 are used to connect the lower CLT board 2 and the upper CLT board 3. However, it is also possible to connect them using only one wooden connecting structure 1, or using three or more wooden connecting structures 1. Furthermore, the first connecting fitting 4 and the second connecting fitting 5 are used as a set, and it is possible to choose at each connection point whether to use the first connecting fitting 4 on top and the second connecting fitting 5 on the bottom, or vice versa. Furthermore, in this embodiment 1, the pin hole 41b3 and groove 51b3 are each formed at one location in the axial direction of the first connecting member 41 and the second connecting member 51, but the pin hole 41b3 and groove 51b3 may be formed at two or more locations in the axial direction of the first connecting member 41 and the second connecting member 51, respectively. Furthermore, in this embodiment 1, one first insertion member 42 is attached to one first connecting member 41 in the first connecting hardware 4, but multiple first insertion members 42 can also be attached to one first connecting member 41. The same applies to the second connecting hardware 5. 【0027】 [Example 1] Figure 9 shows a modified example 1 of the wooden joint structure 1 of Embodiment 1 of the present invention, where (a) is a top view, (b) is a front view, and (c) is a side view. Modification example 1 is a wooden joint structure 1 for connecting a lower CLT board 2 and an upper CLT board 3 so that they intersect at a 60° angle. The wood joint structure 1 of the modified example 1 is generally the same as the wood joint structure 1 of embodiment 1, except that the shapes of the notches 21 and 31 and the arrangement of the first connecting hardware 4 and the second connecting hardware 5 are different. A triangular prism-shaped notch 21 is formed at the upper part of the lower CLT plate 2 where it intersects with the upper CLT plate 3. The triangle at the base of this triangular prism is an equilateral triangle obtained by bisecting the rhombus-shaped portion where the lower CLT plate 2 and the upper CLT plate 3 intersect (hereinafter referred to as the intersection) with one of its diagonals. Similarly, a triangular prism-shaped notch 31 is formed at the lower part of the upper CLT panel 3 where it intersects with the lower CLT panel 2. 【0028】 Furthermore, in this modified example 1, one second connecting fitting 5 is positioned on the underside of the lower end surface of the notch 21 of the lower CLT plate 2, one first connecting fitting 4 is positioned on the underside of the upper end surface of the remaining portion of the intersection of the lower CLT plate 2 other than the notch 21, one second connecting fitting 5 is positioned on the upper side of the upper end surface of the notch 31 of the upper CLT plate 3, and one first connecting fitting 4 is positioned on the upper side of the lower end surface of the remaining portion of the intersection of the upper CLT plate 3 other than the notch 31. 【0029】 [Differentiation 2] Figure 10 shows a modified example 2 of the wood joint structure 1 of Embodiment 1 of the present invention. In Embodiment 1, the first connecting member 41 of the first connecting hardware 4 is housed in the storage recess 22 of the lower CLT plate 2 and the storage recess 32 of the upper CLT plate 3. However, in this Modified Example 2, the lower CLT plate 2 does not have a storage recess 22 and the upper CLT plate 3 does not have a storage recess 32, and the first connecting member 41 is not housed in the storage recess 22 or the storage recess 32, which is the main difference. A first insertion hole 231 is formed on the lower end surface of the notch 21 of the lower CLT plate 2, drilled downwards, into which the first insertion member 42 is screwed, and a male screw 42a is screwed into the first insertion hole 231. In this modified example 2, unlike embodiment 1, the first connecting member 41 is provided protruding from the lower end surface of the notch 21 of the lower CLT plate 2. Furthermore, a first insertion hole 331 is formed on the upper end surface of the notch 31 of the upper CLT plate 3, drilled upward, into which the first insertion member 42 is screwed, and a male screw 42a is screwed into the first insertion hole 331. In this modified example 2, unlike embodiment 1, the first connecting member 41 is provided protruding from the upper end surface of the notch 31 of the upper CLT plate 3. In this modified example 2, the attachment of the second connecting hardware 5 to the lower CLT plate 2 and the upper CLT plate 3 is the same as in Embodiment 1. 【0030】 In this modified example 2, as in embodiment 1, the first connecting member 41 of the first connecting fitting 4 of the lower CLT plate 2 is fitted onto the second connecting member 51 of the second connecting fitting 5 of the upper CLT plate 3, and the first connecting member 41 of the first connecting fitting 4 of the upper CLT plate 3 is fitted onto the second connecting member 51 of the second connecting fitting 5 of the lower CLT plate 2. The lower CLT plate 2 and the upper CLT plate 3 are connected by inserting a drift pin 9 through the pin hole 41b3 of the first connecting member 41 and the groove 51b3 of the second connecting member 51. In this modified example 2, unlike embodiment 1, the first connecting member 41 of the first connecting hardware 4 and the second connecting member 51 of the second connecting hardware 5 are positioned in the space 2a created between the lower end surface of the notch 21 of the lower CLT plate 2 and the lower end surface of the remaining portion of the intersection of the upper CLT plate 3 other than the notch 31, and in the space 3a created between the upper end surface of the notch 31 of the upper CLT plate 3 and the upper end surface of the remaining portion of the intersection of the lower CLT plate 2 other than the notch 21. Thus, since the first connecting member 41 and the second connecting member 51 are not located inside the lower CLT board 2 or the upper CLT board 3, in the wood joint structure of this modified example 2, the drift pins 9 are not used to fix the lower CLT board 2 or the upper CLT board 3 to the first connecting member 41 or the second connecting member 51, and the lower CLT board 2 and the upper CLT board 3 do not have pin insertion holes 24 and 34, respectively. The wood joint structure 1 in this modified example 2 can be constructed more easily than the wood joint structure 1 in embodiment 1. Although 2a and space 3a are visible from the outside, they can be concealed by applying exterior and interior materials. 【0031】 [Difference 3] Figure 11 shows a modified example 3 of the wood joint structure 1 of Embodiment 1 of the present invention. This modified example 3 uses a first insertion member 42 and a second insertion member 52 that are different from those in Embodiment 1. In this modified example 3, the first insertion member 42 and the second insertion member 52 have the same configuration, so the first insertion member 42 will be described below. In Embodiment 1, the first insertion member 42 is formed in a rod shape, and male threads 42a are formed on the circumferential surface except for both ends. In this modified example 3, the first insertion member 42 is formed in a rod shape, similar to 42 in embodiment 1, and has a female thread 42b at one end. Multiple pin holes 42c for inserting the drift pin 9 are formed on the circumferential surface of the first insertion member 42 in the axial direction, perpendicular to the central axis of the first insertion member 42. In this modified example 3, pin insertion holes 24 and 34 are formed in the lower CLT plate 2 and the upper CLT plate 3, and the first insertion member 42 and the lower CLT plate 2 and the upper CLT plate 3 are fixed by aligning the position of the pin hole 42c with the pin insertion holes 24 and 34 and inserting the drift pin 9. The number of pin holes 42c can be appropriately designed, taking into account the lengths of the first insertion member 42 and the second insertion member 52, the fixing strength between the lower CLT plate 2 and the upper CLT plate 3 and the first insertion member 42, etc. 【0032】 Furthermore, the pin insertion holes 24 and 34 in the lower CLT plate 2 and upper CLT plate 3 may be formed so as not to penetrate to the other side surface, as in Embodiment 1, or they may penetrate to the other side surface, as in Embodiment 2 described later. In addition, the drift pin 9 may be a nutted drift pin as in Embodiment 1, or an ordinary drift pin (without a nut) as in Embodiment 2 described later. In Embodiment 1, the pin insertion hole is formed so as not to penetrate to the other side surface, and a nutted drift pin is used. Alternatively, as in Embodiment 2, the pin insertion hole can be made to penetrate to the other side surface, and a regular drift pin (without a nut) can be used. Conversely, in Embodiment 2, the pin insertion hole can be made to penetrate to the other side surface, and a regular drift pin can be used. Alternatively, as in Embodiment 1, the pin insertion hole can be formed so as not to penetrate to the other side surface, and a nutted drift pin can be used. Furthermore, as described above, the second insertion member 52 can be configured in a similar manner. Compared to the wood joint structure 1 of Embodiment 1, this modified example 3 allows for easier insertion of the first insertion member 42 and the second insertion member 52 into the first insertion holes 231, 331 and the second insertion holes 232, 332. 【0033】 [Embodiment 2] The wood joint structure 1 of Embodiment 2 according to the present invention will be described below with reference to the drawings. In this Embodiment 2, CLT boards are used as the wood, but the lower CLT board 2 and the upper CLT board 3 are arranged to intersect at a 45° angle and are connected in this structure. Furthermore, the wood used is not limited to CLT boards; any other type of wood (not limited to laminated timber) is acceptable. Also, the wood is not limited to boards; it may be in other shapes such as rods or blocks. Additionally, the arrangement of the two pieces of wood is not limited to intersecting at a 45-degree angle; they may intersect at any other angle. Furthermore, the wood may be used for any purpose, such as structural or decorative materials. For the sake of explanation, we will use terms that indicate direction, such as up, down, and side, but the direction in which gravity acts is down, and the opposite direction is up. 【0034】 [Overall structure] Figure 12 shows a wooden joint structure 1 of Embodiment 2 of the present invention, where (a) is a view from above, and (b) is an enlarged view of the area around the first connecting member 71 and the second connecting member 81. The wood connecting structure 1 of this embodiment 2 is a structure for connecting a lower CLT board 2 and an upper CLT board 3 (one piece of wood and another piece of wood), and is a structure for connecting an upright upper CLT board 3 on top of an upright lower CLT board 2 so that the lower CLT board 2 and the upper CLT board 3 intersect at a 45° angle. In this embodiment 2, one wooden joint structure 1 is used. The lower CLT panel 2 and the upper CLT panel 3 are rectangular panels of the same thickness. The lower end surface of the upper CLT plate 3 rests on the upper end surface of the lower CLT plate 2. The lower CLT plate 2 and the upper CLT plate 3 intersect at a rhombus-shaped section (hereinafter referred to as the intersection). At this intersection, the lower CLT plate 2 supports the weight of the upper CLT plate 3. 【0035】 The wooden joint structure 1 includes a first connecting fitting 7, a second connecting fitting 8, and a drift pin 9. In this second embodiment, the second connecting fitting 8 (however, the second connecting member 81, which will be described later, protrudes from the upper end surface) is positioned on the underside of the upper end surface of the intersection portion of the lower CLT plate 2, and the first connecting fitting 7 is positioned on the upper side of the lower end surface of the intersection portion of the upper CLT plate 3 (see also Figure 18). Then, the first connecting hardware 7 of the upper CLT plate 3 and the second connecting hardware 8 of the lower CLT plate 2 are connected, thereby connecting the upper CLT plate 3 and the lower CLT plate 2. 【0036】 [First connecting hardware] Figure 13 shows the components of the first connecting hardware 7 used in the wood joint structure 1 of Embodiment 2 of the present invention, where (a) shows the first connecting member 71 and (b) shows the first insertion member 72. (a) is a perspective view, plan view, side view, and bottom view from top to bottom. Figure 14 shows the first connecting hardware 7 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the structure before assembly and (b) shows the structure after assembly. The first connecting fitting 7 has a first connecting member 71 and a first insertion member 72. The first connecting member 71 is formed in a bottomed cylindrical shape and has a first bottom portion 71a and a first cylindrical portion 71b. The first bottom portion 71a has a first insertion member fixing hole 71a1 through which the first insertion member 72 is inserted and fixed. The first cylindrical portion 71b has two pin holes 71b3 formed at opposite locations on the cylinder along a straight line 71b2 perpendicular to the central axis 71b1 of the first cylindrical portion 71b, through which the drift pin 9 is inserted. These two pin holes 71b3 form a pair. The inner diameter of the pin holes 71b3 is formed to be approximately the same as the outer diameter of the drift pin 9, which will be described later. The first insertion member 72 is formed in a rod shape, with male threads 72a on the circumferential surface except for both ends, and male threads 72b on both ends. 【0037】 As shown in Figure 14(a), the first connecting member 71 and the first inserting member 72 are assembled by a nut 73 and a spring washer 74. More specifically, the first connecting member 71 and the first inserting member 72 are assembled by inserting one end of the first inserting member 72 from the outside into the first inserting member fixing hole 71a1 in the first bottom portion 71a of the first connecting member 71, inserting the nut 73 and spring washer 74 through the opening 71c of the first connecting member 71, and fastening the male screw 72a and nut 73, with the spring washer 74 sandwiched between the first bottom portion 71a and nut 73. In this embodiment 2, the first connecting member 71 and the first inserting member 72 are fixed by fastening the male screw 72a and nut 73, but other known mounting means may also be used, for example, by fastening a female screw formed at the end of the first inserting member 72 with a socket head cap screw, as in embodiment 1. As shown in Figure 14(b), the first insertion member 72 is attached to the first bottom portion 71a of the first connecting member 71, extending away from the first connecting member 71 on the central axis 71b1 of the first cylindrical portion 71b. 【0038】 [Second connecting hardware] Figure 15 shows the components of the second connecting hardware 8 used in the wood joint structure 1 of Embodiment 2 of the present invention, where (a) shows the second connecting member 81 and (b) shows the second insertion member 82. (a) is a perspective view, plan view, side view, and bottom view from top to bottom. Figure 16 shows a second connecting metal fitting 8 used in the wood joint structure 1 of Embodiment 1 of the present invention, where (a) shows the structure before assembly and (b) shows the structure after assembly. The second connecting fitting 8 has a second connecting member 81 and a second insertion member 82. The second connecting member 81 is formed in a bottomed cylindrical shape and has a second bottom portion 81a and a second cylindrical portion 81b. The second bottom portion 81a has a second insertion member fixing hole 81a1 through which the second insertion member 82 is inserted and fixed. The second cylindrical portion 81b has two pin holes 81b3 formed on the cylinder at opposite locations along a straight line 81b2 perpendicular to the central axis 81b1 of the second cylindrical portion 81b, through which the drift pin 9 is inserted. These two pin holes 81b3 form a pair. The inner diameter of the pin holes 81b3 is formed to be approximately the same as the outer diameter of the drift pin 9, which will be described later. The second insertion member 82 is formed in a rod shape, with male threads 82a formed on the circumferential surface except for both ends, and male threads 82b formed on both ends. 【0039】 As shown in Figure 16(a), the second connecting member 81 and the second inserting member 82 are assembled by a nut 83 and a spring washer 84. More specifically, one end of the second inserting member 82 is fitted from the outside into the second inserting member fixing hole 81a1 in the second bottom 81a of the second connecting member 81, and the nut 83 and spring washer 84 are inserted through the opening 81c of the second connecting member 81. The male screw 82b and the nut 83 are then fastened together with the spring washer 84 in between. In this second embodiment, the second connecting member 81 and the second inserting member 82 are fixed by fastening the male screw 82a and the nut 83. However, other known mounting means may be used, for example, as in the first embodiment, by fastening a female screw formed at the end of the second inserting member 82 with a socket head cap screw. As shown in Figure 16(b), the second insertion member 82 is attached to the second bottom portion 81a of the second connecting member 81, extending away from the second connecting member 81 on the central axis 81b1 of the second cylindrical portion 81b. 【0040】 [Drift Pin] Figure 17 shows a drift pin 9 used in the wood joint structure 1 of Embodiment 2 of the present invention. In this second embodiment, a drift pin 9 is used which has a tapered portion 9a formed at one end. 【0041】 [Wood connection structure] Figure 18 shows the wooden joint structure 1 of Embodiment 2 of the present invention before connection. Figure 19 shows the connection process of the first connecting hardware 7 and the second connecting hardware 8 used in the wood joint structure 1 of Embodiment 2 of the present invention, and the connection of the first connecting hardware 4 and the second connecting hardware 5 proceeds in the order from (a) to (e). As described above, using the wood joint structure 1, the upper CLT board 3, which is also upright, is connected to the upper CLT board 3, which is also upright, on top of the lower CLT board 2, which is also upright, so that the lower CLT board 2 and the upper CLT board 3 intersect at a 45° angle. A second insertion hole 232 is formed on the upper end surface of the intersection of the lower CLT plate 2, drilled downwards, into which the second connecting hardware 8 is screwed. A storage recess 32 for housing the first connecting member 71 is formed on the lower end surface of the intersection of the upper CLT plate 3. A first insertion hole 331 is formed, drilled upward from the bottom surface of the storage recess 32, into which the first connecting hardware 7 is screwed. Furthermore, a pin insertion hole 34 for inserting a drift pin 9 is formed on the side surface of the upper CLT plate 3 corresponding to the location where the storage recess 32 is formed. The pin insertion hole 34 is drilled from one side surface and is formed to penetrate to the other side surface. (See Figure 12(b)) In this second embodiment, since the pin insertion hole 34 penetrates to the other side, the drift pin 9 can be easily removed. Therefore, in this second embodiment, an ordinary drift pin (without a nut) can be used. 【0042】 The male screw 82a of the second connecting hardware 8 is screwed into the second insertion hole 232 of the lower CLT plate 2, and the second connecting member 81 is provided protruding from the upper end surface of the lower CLT plate 2. The male screw 72a of the first connecting hardware 7 is screwed into the first insertion hole 331 of the upper CLT plate 3, and the first connecting member 71 is housed in the storage recess 32. As shown above, the second connecting hardware 8 is attached to the lower CLT panel 2, and the first connecting hardware 7 is attached to the upper CLT panel 3. 【0043】 The upper CLT plate 3 and the lower CLT plate 2 are connected, with the first connecting fitting 7 and the second connecting fitting 8 attached to them respectively. The upper CLT plate 3 is placed on the upper end surface of the lower CLT plate 2, and the second connecting fitting 8 of the lower CLT plate 2 and the first connecting fitting 7 of the upper CLT plate 3 are connected, thereby connecting the lower CLT plate 2 and the upper CLT plate 3. 【0044】 In the following section, regarding the wood joint structure 1, the lower CLT board 2 and upper CLT board 3 will be omitted, and the connection between the first connecting hardware 7 and the second connecting hardware 8 will be explained. As shown in Figure 19(a), the first connecting fitting 7 attached to the upper CLT panel 3 and the second connecting fitting 8 attached to the lower CLT panel 2 are arranged vertically. (This corresponds to the state shown in Figure 18.) In this state, the position of the pin hole 71b3 of the first connecting member 71 aligns with the position of the pin insertion hole 34 of the upper CLT plate 3. To attach the first connecting hardware 7 to the upper CLT plate 3, first, the male screw 72a of the first insertion member 72 of the first connecting hardware 7 is screwed into the first insertion hole 331 of the upper CLT plate 3. Once the male screw 72a is screwed into the first insertion hole 331, the first insertion member fixing hole 71a1 of the first connecting member 71 is fitted to the end of the first insertion member 72, and the male screw 72b of the first insertion member 72 and the nut 73 are fastened and secured via the spring washer 74. When fixing the first connecting member 71, it is stored in the storage recess 32. However, prior to fixing, if a drift pin 9 is inserted through the pin insertion hole 34 of the upper CLT plate 3 on one side of the upper CLT plate 3 and the pin hole 71b3 of the first connecting hardware 7, the first connecting member 71 and the first insertion member 72 can be fixed together while maintaining the alignment of the pin insertion hole 34 and the pin hole 71b3 without the first connecting member 71 rotating when the nut 73 is tightened. Furthermore, to attach the second connecting hardware 8 to the lower CLT plate 2, first, the male screw 82a of the second insertion member 82 of the second connecting hardware 8 is screwed into the second insertion hole 232 of the lower CLT plate 2. Once the male screw 82a is screwed into the second insertion hole 232, the second insertion member fixing hole 81a1 of the second connecting member 81 is fitted to the end of the second insertion member 82, and the male screw 82b of the second insertion member 82 and the nut 83 are fastened and fixed via the spring washer 84. After that, in order to align the position of the pin hole 81b3 of the second connecting member 81 with the position of the pin insertion hole 34 of the upper CLT plate 3, a rod-shaped member is inserted through the two pin holes 81b3 and the second connecting member 81 is rotated. Note that since the second connecting member 81 is fixed to the second insertion member 82 with the nut 83 via the spring washer 84, the second connecting member 81 can be rotated relative to the second insertion member 82. 【0045】 Next, as shown in Figures 19(b) and (c), the first connecting member 71 of the first connecting fitting 7 is fitted onto the second connecting member 81 of the second connecting fitting 8. As shown in Figure 19(d), once the first connecting member 71 is fitted onto the second connecting member 81, the drift pin 9 is inserted through the pin holes 71b3 and 81b3. In practice, the drift pin 9 is inserted through the pin insertion hole 34 of the upper CLT plate 3. As shown in Figure 19(e), inserting the drift pin 9 completes the connection between the lower CLT plate 2 and the upper CLT plate 3. 【0046】 In this embodiment 2, one wooden connecting structure 1 is used to connect the lower CLT board 2 and the upper CLT board 3, but two or more wooden connecting structures 1 may be used for the connection. Furthermore, the first connecting fitting 7 and the second connecting fitting 8 are used as a set, and it is possible to choose at each connection point whether to use the first connecting fitting 7 on top and the second connecting fitting 8 on the bottom, or vice versa. Furthermore, in this second embodiment, the pin holes 71b3 and 81b3 are each formed at one location in the axial direction of the first connecting member 71 and the second connecting member 81, but two or more pin holes 71b3 and 81b3 may be formed at two or more locations in the axial direction of the first connecting member 71 and the second connecting member 81, respectively. Furthermore, in this second embodiment, one first insertion member 72 is attached to one first connecting member 71 in the first connecting hardware 7, but multiple first insertion members 72 can also be attached to one first connecting member 71. The same applies to the second connecting hardware 8. 【0047】 [Differentiation Example 4] Figure 20 shows a modified example 4 of the wood joint structure 1 of Embodiment 2 of the present invention, where (a) shows the structure before joining and (b) shows the structure after joining. This modified example 4 is an example of connecting three CLT boards, a first CLT board 10-1, a second CLT board 10-2, and a third CLT board 10-3, vertically. The first CLT board 10-1 and the second CLT board 10-2 intersect at 45°, and the first CLT board 10-1 and the third CLT board 10-3 intersect at 30° (the second CLT board 10-2 and the third CLT board 10-3 intersect at 15°). This is a wood joint structure 1 for connecting them. The wood joint structure 1 in modified example 4 is the same as the wood joint structure 1 in embodiment 2. The first CLT panel 10-1, the second CLT panel 10-2, and the third CLT panel 10-3 are all fitted with a first connecting member 71, a second connecting member 81, and a first inserting member 72. The second CLT panel 10-2 will be used as an example for explanation. A first insertion member 72 is screwed into the second CLT plate 10-2, and a first connecting member 71 is fastened to the male thread 72b at the upper end of the first insertion member 72, and a second connecting member 81 is fastened to the male thread 72b at the lower end of the first insertion member 72. The first connecting member 71 protrudes from the upper end surface of the second CLT plate 10-2, and the second connecting member 81 is housed in a storage recess on the lower end surface of the second CLT plate 10-2. Then, as shown in Figure 20(b), the second connecting member 81 at the bottom of the first CLT board 10-1 is connected to the first connecting member 71 at the top of the second CLT board 10-2, and the second connecting member 81 at the bottom of the second CLT board 10-2 is connected to the first connecting member 71 at the top of the third CLT board 10-3, thereby connecting the first CLT board 10-1, the second CLT board 10-2, and the third CLT board 10-3 in this order vertically. In this way, any number of CLT panels can be connected vertically using the wood joint structure 1. 【0048】 [Difference 5] Figure 21 shows a modified example 5 of the wood joint structure 1 of Embodiment 2 of the present invention, where (a) shows the structure before joining and (b) shows the structure after joining. This modified example 5 is almost identical to modified example 2, but differs mainly in the following respects. In Modification 4, one first insertion member 72 is screwed into the first CLT plate 10-1, the second CLT plate 10-2, and the third CLT plate 10-3, with the first connecting member 71 fastened to the male screw 72b at the upper end of the first insertion member 72 and the second connecting member 81 fastened to the male screw 72b at the lower end of the first insertion member 72. However, in Modification 5, the first insertion member 72 is screwed into the upper part of the first CLT plate 10-1, the second CLT plate 10-2, and the third CLT plate 10-3, with the second insertion member 82 screwed into the lower part, with the first connecting member 71 fastened to the male screw 72b at the upper end of the first insertion member 72 and the second connecting member 81 fastened to the male screw 82b at the lower end of the second insertion member 82. Furthermore, variations 4 and 5 can be selected by considering the dimensions of the CLT board height (the length of the first insertion member 72 and the second insertion member 82 in the insertion direction), etc. 【0049】 [Modification 6] Figure 22 shows a modified example 6 of the wood joint structure 1 of Embodiment 2 of the present invention, and is an enlarged view of the vicinity of the first connecting member 71 and the second connecting member 81. Figure 23 shows a modified example 6 of the wood joint structure 1 of Embodiment 2 of the present invention, and is a perspective view showing the first connecting member 71 and the second connecting member 81. In Embodiment 2, the first connecting member 71 of the first connecting hardware 7 is housed in the storage recess 32 of the upper CLT plate 3. However, in this modified example 6, the storage recess 32 is not formed in the upper CLT plate 3, and the first cylindrical portion 71b is not housed in the storage recess 32, which is the main difference. A first insertion hole 331 is formed on the lower end surface of the intersection of the upper CLT plate 3, drilled upwards, into which the first insertion member 72 is screwed, and a male screw 72a is screwed into the first insertion hole 331. In this modified example 6, unlike in embodiment 2, the first connecting member 71 is provided protruding from the lower end surface of the upper CLT plate 3. In this modified example 6, the attachment of the second connecting hardware 8 to the lower CLT plate 2 is the same as in embodiment 2. 【0050】 In this modified example 6, as in embodiment 2, the first connecting member 71 of the first connecting fitting 7 of the upper CLT plate 3 is fitted onto the second connecting member 81 of the second connecting fitting 8 of the lower CLT plate 2, and the lower CLT plate 2 and the upper CLT plate 3 are connected by inserting a drift pin 9 through the pin hole 71b3 of the first connecting member 71 and the pin hole 81b3 of the second connecting member 81. In this modified example 2, unlike embodiment 2, the first connecting member 71 of the first connecting hardware 7 and the second connecting member 81 of the second connecting hardware 8 are positioned in the space created between the upper end surface of the intersection of the lower CLT plate 2 and the lower end surface of the intersection of the upper CLT plate 3. Thus, since the first connecting member 71 and the second connecting member 81 are not located inside the lower CLT board 2 or the upper CLT board 3, in the wood joint structure 1 of this modified example 2, the drift pins 9 are not used to fix the upper CLT board 3 to the first connecting member 71 and the second connecting member, and the lower CLT board 2 and the upper CLT board 3 do not have pin insertion holes 24 and 34, respectively. The wood joint structure 1 in this modified example 6 can be constructed more easily than the wood joint structure 1 in embodiment 2. Although the space between the upper end surface of the intersection of the lower CLT panel 2 and the lower end surface of the intersection of the upper CLT panel 3 is visible from the outside, it can be concealed by applying exterior or interior materials. 【0051】 [Difference 7] Figure 24 shows a modified example 7 of the wood joint structure 1 of Embodiment 2 of the present invention, where the left figure shows the second insertion member 82, the center figure shows the second insertion member 82 before being inserted into the lower CLT board 2, and the right figure shows the second insertion member 82 after being inserted into the lower CLT board 2. This modified example 7 uses a first insertion member 72 and a second insertion member 82 that are different from those in Embodiment 2. In this modified example 64, the first insertion member 72 and the second insertion member 82 have the same configuration, so the second insertion member 82 will be described below. In Embodiment 2, the second insertion member 82 is formed in a rod shape, and male threads 82a are formed on the circumferential surface except for both ends. In this modified example 6, the second insertion member 82 is formed in a rod shape, similar to embodiment 2, and a male screw 82b is formed only at one end, not at both ends. Numerous ribs 82c are formed in the axial direction on the circumferential surface of the second insertion member 82. The lower CLT plate 2 has a first insertion hole 231 into which the second insertion member 82 is inserted, and the second insertion member 82 is inserted into the first insertion hole 231. During this insertion, adhesive G is injected together, and the second insertion member 82 is fixed to the lower CLT plate 2 by the rib 82c and adhesive G. Furthermore, as described above, the first insertion member 72 can be configured in the same manner. 【0052】 As described above, Embodiment 1 and its modifications 1 to 3, and Embodiment 2 and its modifications 4 to 7 according to the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments and modifications, and any design changes, etc., that do not depart from the gist of the present invention are also included. Furthermore, the above-mentioned embodiments and modifications can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose and configuration. 【0053】 As a design change, for example, in Embodiment 1 and its modified versions 1 to 3, and Embodiment 2 and its modified versions 4 to 7, the first insertion members 42, 72 and the second insertion members 52, 82 are all rod-shaped members with male threads 42a, 52a, pin holes 42c, 52c, and ribs 82c formed on the circumferential surface except for both ends. However, at least one of them can be a rod-shaped member without male threads 42a, 52a, pin holes 42c, 52c, or ribs 82c. In that case, the diameters of the first insertion members 42, 72 and the second insertion members 52, 82 are approximately the same as the diameters of the first insertion holes 231, 331 and the second insertion holes 232, 332, respectively, and the first insertion members 42, 72 and the second insertion members 52, 82 are inserted into the first insertion holes 231, 331 and the second insertion holes 232, 332, respectively. 【0054】 As a combination of embodiments and modifications, for example, instead of the configuration of Embodiment 1, in which notches are formed at the intersection of the upper and lower CLT plates and the notches and the remaining parts other than the notches are fitted together, the configuration of Embodiment 2 can be made in which no notches are formed and the lower and upper end surfaces of the upper and lower CLT plates are brought into direct contact. Conversely, instead of the configuration of Embodiment 2 in which the lower and upper end surfaces of the upper and lower CLT plates are brought into direct contact, the configuration of Embodiment 1 can be made in which notches are formed at the intersection of the upper and lower CLT plates and the notches and the remaining parts other than the notches are fitted together. 【0055】 Furthermore, instead of the configuration of Embodiment 1, in which the pin insertion hole is formed so as not to penetrate to the other side surface and a nutted drift pin is used, it is also possible to use a regular drift pin (without a nut) by having the pin insertion hole penetrate to the other side surface, as in Embodiment 2. Conversely, instead of the configuration of Embodiment 2, in which the pin insertion hole penetrates to the other side surface and a regular drift pin is used, it is also possible to use a nutted drift pin by having the pin insertion hole formed so as not to penetrate to the other side surface, as in Embodiment 1. 【0056】 Furthermore, the first connecting fitting 4 and the second connecting fitting 5 of Embodiment 1 can also be used as connecting fittings in the modified examples 4 and 5 of Embodiment 2. Furthermore, the first insertion member 42 and the second insertion member 52 of the modified example 3 of Embodiment 1 can be used in place of the first insertion member 72 and the second insertion member 82 of Embodiment 2, and the first insertion member 72 and the second insertion member 82 of the modified example 7 of Embodiment 2 can be used in place of the first insertion member 42 and the second insertion member 52 of Embodiment 1.
