Description

[Technical Field]

[0001] The present invention relates to a joining structure and a joining method. [Background technology]

[0002] One method of detailing the ends of wooden members when attaching them to surrounding structures is to fit metal members such as gusset plates into grooves formed in the wooden members and fasten them by penetrating the wooden and metal members with drift pins, bolts, etc. Another method of detailing the ends of wooden members when attaching them to surrounding structures is to insert female-threaded LSBs (Lag Screw Bolts) into holes formed in the wooden members and fasten metal members such as gusset plates to the wooden members with bolts, etc. [Prior art documents] [Patent documents]

[0004] Both of the above-mentioned construction methods require forming holes or grooves in the wooden members to attach metal members such as gusset plates. However, simply inserting the gusset plates into these holes or grooves can cause deterioration due to exposure to factors such as ultraviolet rays and water in the gaps around the gusset plates.

[0005] One object of the present invention is to prevent deterioration around holes or grooves formed in wooden members for attaching metal members. Other objects of the present invention will become apparent from the description of this specification. [Means for solving the problem]

[0006] One aspect of the present invention is a plate-shaped member comprising a plate-shaped wooden member having a groove formed on the inside of the outer periphery of the end face, a metal member having a plate-shaped portion that is fitted into the groove, and a filler material that fills the gap between the groove and the metal member.

[0007] Other features of the present invention will become apparent from the following description and drawings. [Effects of the Invention]

[0008] According to the above aspect of the present invention, deterioration of the periphery of a hole or groove formed in a wooden member for attaching a metal member can be suppressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] At least the following matters will become clear from the description of this specification and the accompanying drawings.

[0011] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The same or equivalent components, members, etc. shown in each drawing are designated by the same reference numerals, and redundant explanations will be omitted where appropriate.

[0012] ===This embodiment=== Fig. 1A is a perspective view showing an application example of a plate-shaped member 10 of this embodiment. Fig. 1B is an explanatory diagram of a joint structure 50 of this embodiment. Note that Fig. 1B shows a part of a cross-sectional portion of the upper joint structure 50 of the two joint structures 50 shown in Fig. 1A.

[0013] <<Definition of direction etc.>> First, with reference to FIGS. 1A and 1B, directions and the like in the plate-shaped member 10 of this embodiment will be defined.

[0014] As shown in Figures 1A and 1B, the vertical direction is referred to as the "up-down direction," the vertically upward direction is simply referred to as the "upward direction," and the vertically downward direction is simply referred to as the "downward direction." In the wooden member 11 (described below) of the plate-like member 10 attached to the member 90, among the horizontal directions, the direction parallel to the plate surface of the wooden member 11 is referred to as the "left-right direction," with one direction referred to as the "leftward direction" and the other direction referred to as the "rightward direction." Furthermore, among the horizontal directions, the direction perpendicular to the plate surface of the wooden member 11 is referred to as the "front-rearward direction," with one direction referred to as the "forward direction" and the other direction referred to as the "rearward direction." Note that the right side when looking at the "forward direction" from the "rearward direction" is the "rightward direction," and the left side when looking at the "forward direction" from the "rearward direction" is the "leftward direction."

[0015] 1A and 1B, the up-down direction, left-right direction, and front-rear direction are each represented by a line segment with a double arrow to facilitate understanding of directions and the like in the plate-like member 10. Note that the intersection of these line segments with a double arrow does not indicate the origin of coordinates.

[0016] The above definitions of directions and the like are common to other embodiments in this specification unless otherwise specified.

[0017] <<Summary>> Next, referring again to FIGS. 1A and 1B, an outline of the plate-shaped member 10 of this embodiment will be described.

[0018] The plate-shaped member 10 is a member having a plate-shaped wooden member 11. The wooden member 11 is joined to a member 90 (sometimes referred to as "another member"). To join the wooden member 11 to the member 90, the plate-shaped member 10 further has a metal member 12, a filler 13, and a connecting member 14, and as shown in FIG. 1B, the wooden member 11 and the metal member 12 are joined by the filler 13. Of the plate-shaped member 10, the metal member 12, the filler 13, and the connecting member 14 (not shown in FIG. 1B) are sometimes referred to as a "joining structure 50." The joining structure 50 is a member that joins the wooden member 11 to a member 90 (another member). In other words, the wooden member 11 is joined to the member 90 by the joining structure 50.

[0019] As shown in FIG. 1A, a member 90 to which the plate-like member 10 of this embodiment is applied has an upper member 91 and a lower member 92. In this embodiment, the member 90 is, for example, an architectural structure, the upper member 91 is, for example, an upper slab or a steel beam, and the lower member 92 is, for example, a lower slab. The application example of the plate-like member 10 shown in FIG. 1A is merely an example and is not limited to the above application example. The plate-like member 10 may be installed in a location other than between an upper slab and a lower slab. Furthermore, the member 90 is not limited to an architectural structure.

[0020] In this embodiment, the wooden member 11 is joined to each of the upper member 91 and the lower member 92 between the upper member 91 and the lower member 92 by the joining structures 50. Specifically, the plate-like member 10 has two joining structures 50, and the wooden member 11 is joined to the upper member 91 by the joining structure 50 located on the upper side, and is joined to the lower member 92 by the joining structure 50 located on the lower side.

[0021] <<Configuration>> Next, the configuration of the plate-shaped member 10 of this embodiment will be described with reference to FIGS. 1A and 1B again and also with reference to FIG.

[0022] FIG. 2 is an exploded perspective view of the upper part of the plate-shaped member 10 of this embodiment.

[0023] As described above, the plate-shaped member 10 includes the wooden member 11, the metal member 12, the filler material 13, and the connecting member 14.

[0024] <Wooden Material 11> The wooden member 11 is a plate-like member made of wood. In this embodiment, the wooden member 11 is a louver made of CLT (Cross Laminated Timber). However, the wooden member 11 may be made of a material other than CLT, such as LVL (Laminated Veneer Lumber) or laminated timber. The wooden member 11 may also be made of a combination of CLT, LVL, laminated timber, etc. Furthermore, the wooden member 11 may be something other than a louver, such as a partition or other member.

[0025] The wooden member 11 has a groove 111 formed on the inside of the outer periphery of the end face 110. The groove 111 is a recess recessed from the end face 110. In this embodiment, the opening of the groove 111 is located on the inside of the outer periphery of the end face 110, as shown in Fig. 2. Note that Fig. 2 shows that the groove 111 is formed on the upper end face 110 of the wooden member 11, but as shown in Fig. 1, the groove 111 is also formed on the lower end face 110 of the wooden member 11.

[0026] A plate-shaped portion 120 of the metal member 12, which will be described later, is fitted into the groove 111, and a filler material 13 is filled in the gap between the plate-shaped portion 120 and the groove. In this embodiment, no holes or grooves are formed on the wooden member 11 except on the end faces 110 (for example, on the side faces 113). In this embodiment, the portions other than the inside of the groove 111 (for example, the side faces 113) are exposed to the outdoors. However, the entire wooden member 11, including the portions other than the end faces 110 (for example, the side faces 113), may be placed indoors.

[0027] <Metal member 12> The metal member 12 is a member having a plate-shaped portion 120 made of metal. As shown in Fig. 2, the metal member 12 in this embodiment is entirely composed of the plate-shaped portion 120. However, the metal member 12 may have a protrusion, another plate-shaped portion, etc. in addition to the plate-shaped portion 120.

[0028] 2 shows only the metal member 12 of the joint structure 50 located on the upper side, but as shown in FIG. 1, the plate-like member 10 also has a metal member 12 in the joint structure 50 located on the lower side. Below, the detailed description of the metal member 12 of the joint structure 50 located on the upper side also applies to the metal member 12 of the joint structure 50 located on the lower side.

[0029] The plate-shaped portion 120 has a bonding surface 121. As shown in Fig. 2, the bonding surface 121 is a surface having a bonding surface length L that fits within the groove depth of the groove portion 111. In other words, the bonding surface 121 is a portion of the plate-shaped portion 120 that is fitted into the groove portion 111. Then, as will be described later, a filler 13 is filled into the gap between the bonding surface 121 and the inner surface of the groove portion 111.

[0030] A hole 122 is formed in the upper part of the joining surface 121 of the plate-shaped portion 120. The fastening member 15 passes through the hole 122. The fastening member 15 passes through the hole 122 and fastens the plate-shaped portion 120 of the metal member 12 to a splice portion 140 (described later) of the connecting member 14. The fastening member 15 is, for example, a bolt.

[0031] <Filling material 13> The filler 13 is a material that fills the gap between the groove 111 of the wooden member 11 and the joining surface 121 of the metal member 12. The filler 13 joins the wooden member 11 and the metal member 12 by filling the gap between the groove 111 of the wooden member 11 and the joining surface 121 of the metal member 12. The filler 13 may be an adhesive such as resin, or may be mortar.

[0032] It should be noted that the filler 13 is not shown in Fig. 2. As described above, only the joint structure 50 located on the upper side is shown in Fig. 2, but as shown in Fig. 1, the plate-like member 10 also has a joint structure 50 located on the lower side. Therefore, the description of the filler 13 described above is common to both the joint structure 50 located on the upper side and the joint structure 50 located on the lower side.

[0033] <Connection member 14> The connecting member 14 is a member for connecting the metal member 12 and the member 90. The connecting member 14 is formed of, for example, metal. In FIG. 2, only the connecting member 14 of the joining structure 50 located on the upper side is shown, but as shown in FIG. 1, the plate-like member 10 also has a connecting member 14 in the joining structure 50 located on the lower side. Below, the detailed description of the connecting member 14 of the joining structure 50 located on the upper side also applies to the connecting member 14 of the joining structure 50 located on the lower side.

[0034] The connecting member 14 has a press-fitting portion 140 and a flange portion 141. The press-fitting portion 140 has a press-fitting surface 142 that is pressed against the plate-like portion 120 of the metal member 12. A hole 144 is formed in the press-fitting portion 140. The hole 144 is a hole through which the fastening member 15 described above passes. The fastening member 15 passes through the hole 144 to fasten the plate-like portion 120 of the metal member 12 and the press-fitting portion 140 of the connecting member 14. The flange portion 141 has a flange surface 143 that is surface-joined with the member 90. The flange surface 143 is surface-joined with the member 90, so that the connecting member 14 is joined to the member 90 with a fastening member such as an anchor bolt (not shown). An anchor bolt hole 146 is formed in the flange portion 141, into which an anchor bolt is inserted. However, if the member 90 to be joined is, for example, a steel beam, the anchor bolt holes 146 may not be formed, and instead a welding member may be formed. The connecting member 14 may be joined to the member 90 by welding. Here, the flange surface 143 is perpendicular to the splice surface 142.

[0035] As described above, the wooden member 11 and the metal member 12 are joined via the filler material 13. Furthermore, the metal member 12 is fastened to the connecting member 14, and the connecting member 14 is joined to the member 90. In this way, the wooden member 11 is attached by being joined to the member 90 via the joining structure 50 (the metal member 12, the filler material 13, and the connecting member 14).

[0036] It should be noted that the plate-like member 10 does not necessarily have to have the connecting member 14. In this case, the metal member 12 may have a flange portion that is surface-joined to the member 90, and the metal member 12 may be joined to the member 90 without the connecting member 14. However, as in this embodiment, the joining structure 50 separates the metal member 12 on the wooden member 11 side (joined to the wooden member 11) from the connecting member 14 on the member 90 side (joined to the member 90), which makes it possible to easily attach the wooden member 11 to the member 90. This point will be described in detail later.

[0037] <<Comparative Example>> FIG. 3 is an exploded perspective view of the lower part of the plate-shaped member 10A of the first comparative example.

[0038] In the plate-shaped member 10 of the present embodiment described above, a groove 111 is formed on the inner side of the outer periphery of the end face 110 of the wooden member 11. In contrast, in the plate-shaped member 10A of the first comparative example, a hole 112A is formed in the side face 113 of the wooden member 11A. The fastening member 15A passes through the hole 112A. Furthermore, in the plate-shaped member 10 of the present embodiment described above, the wooden member 11 and the metal member 12 are joined via the filler material 13 filled in the groove 111 of the wooden member 11. In contrast, in the plate-shaped member 10A of the first comparative example, the fastening member 15A passes through the hole 112A and directly fastens the metal member 12A to the wooden member 11A. An anchor bolt hole 124 is formed in the bottom of the metal member 12A, and the metal member 12A is joined to a member 90 (not shown) with a fastening member such as an anchor bolt.

[0039] In the plate-shaped member 10A of the first comparative example, the hole 122A formed in the metal member 12A must be larger in diameter than the fastening member 15A. Therefore, even if the wooden member 11A and the metal member 12A are fastened together by the fastening member 15A, there is a possibility that rattle may occur. In other words, the initial rigidity of the plate-shaped member 10A may be reduced.

[0040] When the plate-shaped member 10A is exposed outdoors, the area around the hole 112A formed in the side surface 113 of the wooden member 11A for attaching the metal member 12A comes into contact with deteriorating factors such as water, which can cause deterioration. Specifically, moisture entering through the hole 122A through which the fastening member 15A passes can cause deterioration around the hole 112A or cracks originating from the hole 112A. Furthermore, when the plate-shaped member 10A is exposed outdoors, the wooden member 11A may be treated (weather-resistant treatment) or painted (weather-resistant coating) to improve its weather resistance. In this case, friction between the fastening member 15A and the wooden member 11A can cause deterioration of the weather-resistant treatment or weather-resistant coating.

[0041] FIG. 4 is an exploded perspective view of the upper part of a plate-shaped member 10B of the second comparative example.

[0042] In the plate-shaped member 10 of the present embodiment described above, the groove 111 was formed on the inside of the outer periphery of the end face 110 of the wooden member 11. In contrast, in the plate-shaped member 10B of the second comparative example, a hole 112B was formed in the side face 113 of the wooden member 11B. The hole 112B is a hole through which the fastening member 15B passes. Furthermore, in the plate-shaped member 10B of the second comparative example, the groove 111B is formed not only on the end face 110 of the wooden member 11B but also on the side face 113. The groove 111B is a groove into which the plate-shaped portion 120B of the metal member 12B is fitted. Furthermore, in the plate-shaped member 10 of the present embodiment described above, the wooden member 11 and the metal member 12 were joined via the filler 13 filled in the groove 111 of the wooden member 11. In contrast to this, in the plate-shaped member 10B of the second comparative example, the fastening member 15B passes through the hole 112B and directly fastens the metal member 12B to the wooden member 11B.

[0043] Here, even in the plate-shaped member 10B of the second comparative example, the hole 122B formed in the metal member 12B must be larger in diameter than the fastening member 15B. Therefore, even if the wooden member 11B and the metal member 12B are fastened together by the fastening member 15B, there is a possibility of rattle. In other words, the initial rigidity of the plate-shaped member 10B may be reduced. Furthermore, a longitudinal load on the fastening member 15B may generate a prying force on the wooden member 11B, increasing the likelihood of localized depression. This may result in cracking of the wooden member 11B. Furthermore, a longitudinal load on the fastening member 15A may generate a prying force on the wooden member 11A, increasing the likelihood of localized depression. This may result in cracking of the wooden member 11A.

[0044] When the plate-shaped member 10B is exposed outdoors, the areas around the holes 112B and grooves 111B formed in the side surface 113 of the wooden member 11B for attaching the metal member 12B are exposed to deterioration factors such as ultraviolet light and water, which can cause deterioration of the areas around the holes 112B and grooves 111B. Specifically, moisture entering through the holes 122B and grooves 111B through which the fastening members 15B pass can cause deterioration of the areas around the holes 112B and grooves 111B or cracks originating from the holes 112B and grooves 111B. Furthermore, when the plate-shaped member 10B is exposed outdoors, the wooden member 11B may be subjected to a treatment (weather-resistant treatment) or painting (weather-resistant coating) to improve its weather resistance. In this case, the weather-resistant treatment or weather-resistant coating may be deteriorated due to friction with the fastening members 15B.

[0045] Unlike the plate-shaped member 10A of the first comparative example and the plate-shaped member 10B of the second comparative example described above, in the plate-shaped member 10 of this embodiment, the wooden member 11 and the metal member 12 are joined together via a filler 13. Grooves 111 formed on the end surface 110 of the wooden member 11 are filled with the filler 13, and no holes or grooves are formed on other surfaces of the wooden member 11 (for example, the side surfaces 113). Therefore, in the plate-shaped member 10 of this embodiment, deterioration of the areas around the holes and grooves formed in the wooden member 11 for attaching the metal members 12 can be suppressed.

[0046] In addition, in plate-shaped member 10 of this embodiment, fastening member 15 fastens metal member 12, which is made of metal, to connecting member 14, thereby reducing the possibility of rattle occurring. Furthermore, in plate-shaped member 10 of this embodiment, when filler 13 is an adhesive, the adhesive force of the adhesive can transmit stress in the tensile direction of plate-shaped portion 120 as well, thereby reducing prying force on wooden member 11A and reducing localized sinking of groove portion 111.

[0047] <<Modifications>> FIG. 5 is an exploded perspective view of the upper part of a plate-shaped member 10C of the first modified example.

[0048] In the plate-shaped member 10 of the present embodiment described above, the end surface 110 of the wooden member 11, in which the groove 111 is formed, is configured as a flat surface. However, as in the wooden member 11C of the plate-shaped member 10C of the first modified example shown in FIG. 5 , a recess 111 may be formed in the end surface 110, and the opening of the groove 111 may be located in the recess 111. Even in this case, the opening of the groove 111 is located inside the outer periphery of the end surface 110. In the plate-shaped member 10C of the first modified example, deterioration of the periphery of the hole or groove formed in the wooden member 11C for attaching the metal member 12 can also be suppressed.

[0049] FIG. 6 is an exploded perspective view of the lower part of a plate-shaped member 10D of the second modified example.

[0050] In the plate-shaped member 10 of the present embodiment described above, the plate-shaped portion 120 of the metal member 12 and the splice portion 140 of the connecting member 14 are fastened together by the fastening member 15 passing through the hole 122. The plate-shaped member 10D of the second modified example may have a metal member 12D different from the metal member 12 of the present embodiment, or a connecting member 14D different from the connecting member 14 of the present embodiment.

[0051] As shown in Fig. 6, the metal member 12D has a protrusion 123 in addition to the hole 122. Also, as shown in Fig. 6, the connecting member 14D has a notch 145 formed therein. In the plate-shaped member 10D of the second modified example, the protrusion 123 can be fitted into the notch 145 to easily position the plate-shaped member 10D, and the plate-shaped member 120D of the metal member 12D can be easily attached to the attachment portion 140D of the connecting member 14D. Note that the plate-shaped member 10D of the second modified example also makes it possible to prevent deterioration of the periphery of the hole or groove formed in the wooden member 11D for attaching the metal member 12D.

[0052] <<Joining procedure>> FIG. 7 is a flow diagram of the joining procedure of this embodiment.

[0053] First, a groove 111 is formed inside the outer periphery of the end surface 110 of the wooden member 11 of the plate-like member 10 (S001, groove forming step).

[0054] Fig. 8A is an explanatory diagram showing the state before grooves 111 are formed on the end surface 110 of the wooden member 11 with the groove forming tool 70. Fig. 8B is an explanatory diagram showing the state after grooves 111 have been formed on the end surface 110 of the wooden member 11 with the groove forming tool 70.

[0055] In the joining procedure of this embodiment, when forming the grooves 111 on the end surfaces 110 of the wooden members 11, a groove forming tool 70 such as a chainsaw shown in Fig. 8A may be used. This makes it possible to easily form the grooves 111 on the end surfaces 110 of the wooden members 11.

[0056] Next, the plate-shaped portion 120 of the metal member 12 is fitted into the groove 111 of the wooden member 11 (S002, metal member fitting step). Then, the filler 13 is filled into the gap between the groove 111 and the plate-shaped portion 120 of the metal member 12 (specifically, the joining surface 121) (S003, filling step).

[0057] Fig. 9A is an explanatory diagram showing the state before the metal member 12 is fitted into the groove 111 formed in the end surface 110 of the wooden member 11. Fig. 9B is an explanatory diagram showing the state in which the metal member 12 is fitted into the groove 111 formed in the end surface 110 of the wooden member 11 and the filler material 13 is filled in.

[0058] In the joining procedure of this embodiment, as shown in FIG. 9A, the metal member 12 is arranged so as to be fitted horizontally into the groove 111. Then, as shown in FIG. 9B, the filler 13 is filled horizontally. In this case, a path is provided for sending the filler 13 to the back of the groove 111 using a filler filling hose or the like, and the filler 13 is filled so as to spread evenly from the back of the groove 111. This allows the filler 13 to be filled evenly into the groove 111. However, as long as the filling ability can be confirmed, the filler 13 does not have to be filled horizontally.

[0059] Finally, the metal member 12 and the member 90 are connected (S004, connecting step). In this embodiment, the connecting step is performed after the above-described groove forming step (S001), the above-described metal member fitting step (S002), and the above-described filling step (S003) have been performed in advance.

[0060] Fig. 10A is an explanatory diagram showing the state before the connecting member 14 joined to the member 90 and the metal member 12 joined to the wooden member 11 are connected. Fig. 10B is an explanatory diagram showing the state after the connecting member 14 joined to the member 90 and the metal member 12 joined to the wooden member 11 are connected.

[0061] In the plate-shaped member 10 of this embodiment, the metal member 12 on the wooden member 11 side (joined to the wooden member 11) and the connecting member 14 on the member 90 side (joined to the member 90) are separated. This allows the metal member 12 to be joined to the wooden member 11 in advance, and the connecting member 14 to the member 90 with anchor bolts 147, as shown in FIG. 10A .
