Description

  The present invention includes a joining structure of wooden members for connecting wooden members to each other to form a building material for a wooden structure such as a wooden floor panel, a wooden wall panel, a wooden beam, a wooden pillar, and the like. The present invention relates to structural wooden building materials and joining methods.

  Building materials using wood include structural laminated members such as columns and beams, and interior laminated members such as plywood and laminated plates, and these are laminated materials that are bonded together with a chemical adhesive. It is known that the adhesive contains volatile harmful substances, and if it exceeds a certain ratio, it may affect health. Since the service life of the adhesive is much shorter than the service life of the joining member made of wood, it is also known that the joining structure made of wood is more friendly to the living environment and has a longer useful life.

  For this reason, today, there is a demand for a method of joining wooden members having a joining surface without using an adhesive or a hardware.

  Conventionally, as a joint structure between wooden members, the following joint structures (1) to (3) are known. (1) Joining with a rod-like wedge or joining with a dowel, (2) Joining with a plate-like wedge, (3) A continuous follow-up plug joining method is known.

  As shown in FIGS. 32 (a) and 32 (c), the joint (1) with the rod-shaped wedge or the dowel is joined with the wooden rod-shaped wedge 30 or FIGS. 32 (b) (c) at right angles to the overlapping surface 2 of the wooden member 1. ), A through-hole 32 is provided in one wooden member 1 and the other wooden member 1, as shown in FIG. 32A, and a rod-like wedge 30 is used. Are provided in the through holes 32 to connect the wooden members 1 to each other, or as shown in FIG. 32 (b), a concave portion 33 is provided on the joining surface of one wooden member 1 and the other wooden member 1, By fitting the dowels 31 so as to be press-fitted into both recesses, the wooden members 1 are connected to each other. In the case of such a structure, when a tensile stress as indicated by an arrow T acts between the wooden members 1 and 1, a bending moment M is generated at the joint, and the bending moment M causes a perpendicular to the overlapping surface. A sufficient shearing force P acts, and a structure that withstands the pulling out of the rod-shaped wedge 30 or the dowel shaft direction with the friction force in the wooden rod-shaped wedge 30 or the dowel shaft direction with respect to the shear force P is obtained, so that a sufficient joining force is obtained It is difficult to apply to structural members. In the case of the wooden rod wedge 30 and the dowel 31 as described above, the cross-sectional area of the wooden rod wedge 30 and the dowel 31 resisting by the shearing force is small as shown in FIG. There is a problem that it is not possible to achieve strong bonding with respect to the tensile force T as shown.

  As shown in FIG. 32 (d), the joining structure using the plate-shaped wedge of (2) is provided with a fitting groove 34 having an opening on the overlapping surface side on one wooden member 1 and on the other wooden member 1. A fitting groove 34 having an opening on the overlapping surface side is provided, the overlapping surfaces of the wooden members are overlapped so that the fitting grooves 34 face each other, and a plate-like wedge 36 is driven into the fitted fitting hole 35. The wooden members 1 are connected to each other. Also in the case of this joining structure, when the tensile stress T as shown by the arrow T is applied to the plate-like wedge 36 as described above, a bending moment M is generated at the joining portion. A force that rotates the wedge 36 and a shearing force H that separates the plate-like members 1 are generated, and the resistance force that opposes the shearing force H is minimal, as shown in FIG. In addition, it is necessary to have a structure for joining with joining brackets such as bolts 37 and nuts 38.

  In the case of the continuous chasing plug joint method of (3) above, the receiving groove 41 and the locking protrusion having a locking groove on one wooden member 40 with the structure as shown in FIGS. 34 (a) to (c). Are alternately provided, receiving grooves 44 having locking grooves on the other wooden member 43 and insertion parts 45 having locking protrusions are alternately provided on the receiving grooves 41 of the one wooden member 40. This is a method of fitting the insertion portion 45 having the locking projection in the other wooden member 43 and driving the wedge 46 into the gap between the fitted portions. In the case of this construction method, when a tensile stress T as shown by an arrow T acts on the wooden members 40 and 43, the locking projections of the insertion portion 45 and the locking projections on the receiving groove 41 side are shown in FIG. A lateral force as indicated by an arrow P is applied to a), and a bending moment M is generated accordingly, and the shearing force Y as indicated by a black arrow in FIG. It acts on the locking projection of the insertion portion 45 and the locking projection on the receiving groove 44 side. As shown in FIG. 34 (c), when tensile forces T in different directions act on one wooden member 40 and the other wooden member 43, the locking projection side at the tip of the insertion portion 42 is substantially centered. As a result, the shearing force S generated on the wedge 46 side and the shearing force S1 applied on the insertion portion 42 have opposite directions and different sizes. There is a problem that the shearing force Y acts on the locking projection and the locking projection on the receiving groove 44 side, and the burden is increased.

  Conventionally, as shown in FIG. 30, the first dovetail groove 51 is provided on the vertical side surface of one end of the wooden member 50 adjacent in the lateral direction so as to intersect at the corner so as to extend in the vertical direction. The second dovetail groove 52 opposite to the first dovetail groove 51 is provided on the vertical side of the end of the other wooden member 53 so as to extend in the vertical direction. There is known a joining structure in which a wooden joining member 55 having an inclined surface 54 that is inclined so as to approach each other in the thickness direction so as to be fitted to the dovetail groove 52 is fitted ( For example, refer nonpatent literature 1). In the case of the structure shown in FIG. 30, when a tensile force T as shown by an arrow T acts on the wooden member 50 and the wooden member 53 as shown in FIG. 33, the reaction force is received by the inclined surface 54 on one side. In addition, stress is applied in the direction in which the peeling failure occurs at the inward portion on the dovetail opening side, and the first dovetail groove 51 of the wooden member 50 or the second dovetail groove 52 portion of the wooden member 53 There is a problem that there is a high risk of damage.

Moreover, the junction structure as shown to Fig.31 (a) (c) (f) (g) is also known (for example, refer nonpatent literature 2). In the case of the joining structure of FIG. 31 (a), the first dovetail groove 51 and the first dovetail groove 51 provided on the opposite side end surfaces of one wooden member 50 and the other wooden member 53 which are adjacent in parallel in the horizontal direction. It is a joining form in which a wooden joining member 55 as shown in FIG. In the case of the joining structure of FIG. 31 (c), when the dovetail groove 51 or dovetail groove 52 as shown in FIG. 31 (d) is formed in one wooden member 50 or the other wooden member 53, This is a form in which a joining member 55 as shown in FIG. 31 (e) is fitted and joined across the first dovetail groove 51 and the second dovetail groove 52. In the case of FIG. 31 (f), the first dovetail groove 51 and the second dovetail groove 52 are hollow columnar dovetails on the back side, and circular ends are formed at both ends of the wooden joining member 55. It is the form which fitted and joined the wooden joining member 55 provided with the columnar part. Further, in the embodiment shown in FIG. 31 (g), the corrugated joining member 56 made of steel plate is driven in between the end portions of one wooden member 50 and the other wooden member 53 which are adjacent in parallel in the horizontal direction. The wooden members adjacent in the lateral direction are joined together.
In the case of the structure shown in FIG. 31 (f), when the wooden joining member 50 is a wedge-shaped member and the first dovetail groove 51 and the second dovetail groove 52 are long holes, as shown in FIG. 33 (b). In addition, there is a problem that it is difficult to drive the wedge-shaped wooden joining member 55. Moreover, since the plate | board thickness of the intermediate part of the wooden joining member 55 is thin, there exists a problem that shear resistance is small and joining force is also small.

Concentration occurs, and since the thickness is thin at the part from the opening, resistance stress or bending force acts on that part, so there is a possibility that the wooden part may be damaged at the thin part. Further, the wooden member is uniformly distributed over the entire length in the vertical direction (or thickness direction) of the wooden member, and over the entire length in the vertical direction (or thickness direction) of the wooden joining member 55.

In the embodiment in which two wooden joining members 10 are provided at an interval in the groove width direction, a wedge device 12 may be provided between them. In this case, the engaging portion between the wooden joining member 10 and the wedge device 12 is provided as follows. It is good also as a form which makes it fit and engage. In the following, description will be made more specifically in the order shown in FIG.

  With reference to Fig.1 (a), FIG.3 (a), FIG.5 and FIG.6, the joining structure of the wooden member of 1st Embodiment of this invention is demonstrated. In the cross section, a bonding groove 3 having a width dimension on the groove back side larger than a width dimension on the opening side is provided on the surface side on which the wooden member 1 is superposed. The joining groove 3 has a groove inner side wall surface including a groove inner vertical wall surface 13 perpendicular to the overlapping surface and a locking groove 14 connected to the groove inner side wall surface at one end in the groove width direction. The groove inner side wall surface at the other end in the groove width direction is a groove inner vertical wall surface 13 perpendicular to the overlapping surface, and the other groove inner vertical wall surface 13 and the inner surface of the locking groove 14 are parallel to the overlapping surface. Connected to the groove inner bottom surface 15, a bonding groove 3 is formed in which the width dimension on the groove back side is larger than the width dimension on the opening side on the surface side that is overlapped in the cross section. A plurality of such joining grooves 3 are provided as wooden members 1 provided in parallel at intervals, and the joining grooves 3 are symmetrically arranged around the overlapping surface so that each of the wooden members 1 faces each other. The wooden member 1 is matched so that it becomes. Or it superposes | polymerizes so that the wooden member 1 juxtaposed and the wooden member 1 juxtaposed may be made to oppose. In this way, the wood members 1 are superposed on each other, or the wood members 1 arranged in parallel are superposed on each other to form a closed joint hole 9, and the close joint holes 9 are parallel to each other at intervals. A plurality are provided.

  A plurality of the closing joint holes 9 are provided so as to penetrate in the width direction of the wooden member 1 at intervals in the longitudinal direction of the wooden member 1. If necessary, as shown in FIG. 22, a closed joining hole 9 using a joining groove 3 formed jointly with the wooden members 1 adjacent to the end portions of the members arranged in the plate width direction. It is good. In such a case, only one side of the joining groove 3 may be formed at the end of the wooden member 1.

  In the form of FIG. 1 (a), as shown in FIG. 6, a wooden joint member 10 is disposed on one side of the groove width direction in the closing joint hole 9 as described above, and a pair of wooden wedge pieces 16 is provided. Are arranged symmetrically with respect to each other, and the wedge device 12 in which the inclined surfaces 17 are opposed to each other is arranged in a state where the lateral width dimension is small, and then the pair of wooden wedge pieces 16 are arranged in the width dimension in the groove width direction. Is pushed in the direction in which the width of the wooden joint member 10 is increased, and the wooden joining member 10 is pressed by the back surface of the one wooden wedge piece 16 so that the wooden joining member 10 is inserted into each groove inner vertical wall surface 13 and the locking groove 14 in the groove width direction. Each wooden wedge piece 16 is pushed in so that the entire rear surface of the other wooden wedge piece 16 is pressed against the other groove inner vertical wall surface 13. In this way, a joining structure capable of increasing the plate thickness is obtained. If the wooden joint member 10 and the wooden wedge piece 16 are slightly smaller than the groove height dimension of the closing joint hole 9, the insertion work is facilitated, and the long wooden joint member 10 and the wooden wedge piece 16 are used. However, although it becomes easy to insert across the joining grooves 3 of the wooden members 1 arranged in parallel, the dimensions may be almost the same as the height of the grooves of the closing joining holes 9.

  As shown in FIGS. 1, 6, or 13, the wooden joining member 10 is arranged in the longitudinal direction of the member in order to match the groove inner vertical wall surface 13 and the locking groove 14 in the closing joining hole 9. Corresponding to one end side in the groove width direction with a right-angle cross section, one side surface is provided with a side wall surface 18 and an engaging protrusion 19 perpendicular to the overlapping surface, and on the opposite side, corresponding to the wedge device 12. The side wall surface 20 is perpendicular to the polymerization surface. The inclination angle (angle formed with the overlapping surface 2) of the inclined surface on the side wall surface 18 side of the engagement protrusion 19 is, for example, about 5 ° to 20 ° (for example, 5 °, 10 °, 15 °, 20 °). It is preferable that this angle is small because the shearing force acting on the engagement protrusion 19 is small.

  As shown in FIG. 18 (a) or FIG. 19 (a) (b), the wedge device 12 having the pair of wooden wedge pieces 16 has a flat surface 21 on one side and an inclined surface having a gradient on the opposite surface. In the wedge device 12 composed of a pair of wooden wedge pieces 16 having a surface 17, a large number of inclined surfaces 17 are provided continuously via respective boundary step portions 22, and the pair of wedge pieces 16 are provided with the inclined surfaces 17. It is good also as the wedge apparatus 12 of the form piled up closely. When the wedge device 12 installed in the closing joint hole 9 is short, as shown in FIG. 18, a plurality of wedges are connected in series by matching the pitch of the inclined surface 17 of the wedge piece 16 and the boundary step portion 22. It may be a wedge device in which the pieces 16 are arranged. The configuration shown in FIG. 19 may be a wedge device 12 in which the amount of movement in the groove width direction may be small, and such a wedge device may be used.

  Note that the ends of the wooden joining member 9 and the wooden wedge device 12 protruding from the joining groove 3 of the wooden member 1 are appropriately cut so as to match the end face of the wooden member (not shown).

  In the joining structure of the wooden member such as the wooden member or the wooden panel unit 6 shown in FIG. 29, the joining groove 3 formed in the wooden member 1 or the wooden panel unit 6 is used. Superposition at the overlapping surface 2 forms a closed joint hole 9, and a pair of wooden joint members 10 having wedge devices 12 are inserted into the closed joint hole 9 and widened in the groove width direction to form a wooden joint. A joining structure in which the members 1 are joined is employed.

  In the second embodiment shown in FIG. 1 (b), in the groove width direction of the closing joint hole 9, one end side of the closing joining hole 9 and the wooden joining member 10, the closing joining hole 9 and the wooden joining member 10 are provided. The end side is the same as that in the first embodiment, but the engagement structure between the wooden joining member 10 and the wedge device 12 is different from that in the above embodiment. In this embodiment, an engagement convex portion 23 is provided on one of the engagement surfaces of the wooden joining member 10 and the pressing wedge device 12, and an engagement concave portion 24 is provided on the other, and the engagement convex portion 23 is engaged with the engagement convex portion 23. The recess 24 is continuously fitted over the longitudinal direction of the closing joint hole 9. In the illustrated form, the wooden joining member 10 has a cross section perpendicular to the longitudinal direction of the member, and has a symmetrical shape in the vertical and horizontal directions. The wooden joint member 10 can be used in the same manner even if it is reversed and not reversed. Further, one wedge piece 16 on the side of the wedge device 12 has stepped portions on both sides in the height direction of the closing joint hole 9 and a pressing surface perpendicular to the overlapping surface 2 with a flat pressing surface at the center. And a wedge piece 16 having an engagement convex portion 23 whose one end is vertically symmetrical with respect to the overlapping surface 2 is used. Then, the engagement concave portion 24 of the wooden joining member 10 and the engagement convex portion 23 of one wedge piece 16 are engaged so as to be fitted. Thus, the wooden joining member 10 and the one wedge piece 16 are fitted to each other, thereby preventing the displacement in the height direction of the closing joining hole 9 between the wooden joining member 10 and the one wedge piece 16. At the same time, the eccentricity of the wedge piece 16 can be prevented. Further, in the illustrated form, the inner surface on the overlapping surface side of the locking convex portion 19 of the wooden joint member 10 is a gently inclined inner inclined surface, and the engaging convex portion 23 on the wedge piece 16 side can be engaged with this. Has an inclined surface on the outside so as to be tapered. FIG. 8A shows a cross section from which the wedge device 12 is taken out, and FIG. 8B shows an enlarged flat cross section. The inclination angle of the inclined surface on the side wall surface 24 side of the engaging protrusion 19 (the angle formed with the overlapping surface 2) is the same as the inclined angle of the inclined surface on the engaging convex portion 23 side, for example, 5 ° to 20 °. The degree (for example, 5 °, 10 °, 15 °, 20 °) may be sufficient, and a smaller angle is desirable because a bending force acting on the engaging protrusion 19 is reduced. The inclined surface on the engagement protrusion 19 side and the inclined surface on the engagement convex portion 23 side are pressure-bonded to each other. It can be engaged by being guided by the mutual guide action of the inclined surface on the engagement protrusion 19 side and the inclined surface on the engagement convex portion 23 side. The same applies to the following embodiments.

  In the wedge device 12 shown in FIG. 8, the wedge device 12 has a configuration in which a large number of parallel inclined surfaces 17 are continuously provided via respective boundary step portions 22 on the overlapping surface side of the wedge pieces 16. . In addition, when the length of the wedge piece 16 is short, for example, the cross-sectional shape of the wedge is different, but as shown in FIG. 11B, the inclined surface 17 and the boundary stepped portion 22 are alternately continuous. By installing the wedge pieces 16 in series and also installing the wooden joining member 10 in series, it is possible to cope with a case where the joining groove 3 is long.

  In the third embodiment shown in FIG. 1 (c), the joining groove 3 has a cross-sectional shape that is symmetrical with respect to the central axis perpendicular to the groove width direction (left-right direction in FIG. 1c). The closed joining hole 9 formed by polymerization is also formed in a cross-sectional form having a symmetrical shape with respect to the central axis perpendicular to the groove width direction. One end side of the joining groove 3 in the groove width direction is the same as in FIG. 1A, and the other end side is symmetrical with the one end side. That is, the groove inner side wall surface at the other end in the groove width direction is a groove inner side wall surface provided with a groove inner vertical wall surface 13 perpendicular to the overlapping surface and a locking groove 14 connected thereto. Further, the pair of left and right wooden joining members 10 can be widened in the groove width direction, and the back side of each of the left and right wooden joining members 10 is an inclined surface 17 inclined in the groove longitudinal direction, one of which is in the groove longitudinal direction. The inclined surface 17 has a gradually increasing thickness, and the other has an inclined surface 17 that has a gradually decreasing thickness in the longitudinal direction of the groove. The inclined surfaces are overlapped with each other and press-fitted to increase the thickness of each other. Thus, both the wooden joining members 10 are moved in the groove width direction, and each wooden joining member 10 is joined in a state in which the inner surface of the joining groove 3 of each wooden member 1 is pressed, and the joining structure is integrated. Has been. FIG. 9 shows a state in which a pair of wooden joining members 10 are inserted and disposed in the closing joint holes 9 with the dimensions in the groove width direction between the wooden joining members 10 being reduced. A state in which the joining member 10 is press-fitted, the engaging portion is moved in the groove width direction, and each wooden joining member 10 is pressed against the inner surface of the closing joining hole 9 is shown. In the form shown in FIG. 1C, the wedge device 12 is formed on the back surfaces of the wooden joining members 10 by providing the inclined surfaces 17 on the contact surfaces of the wooden joining members 10. The wedge piece 16 can be omitted.

  In the form of FIG. 1 (c), a form in which each of the wooden joining members 10 is superposed is replaced with the wooden joining member 10 in a form in which the inclined surface 17 is connected via the boundary step part 22. FIG. a) (b) (c). Since other forms are the same as the form shown in FIG. 1C, the same reference numerals are given to the same parts.

  Referring to FIG. 35, the case where tensile stress T acts on the joint structure of the third embodiment shown in FIG. 1 (c) and the fourth embodiment shown in FIG. 1 (d) will be described. As shown in FIG. 4, with the tensile stress T, the pressing force P is applied from the wooden member 1 side to the wooden joining member 10 and from each pressing surface perpendicular to the overlapping surface of the wooden members to each side surface of the wooden joining member 10. This is because the resisting force is received by a surface perpendicular to the tensile stress T in the longitudinal direction of the member, so that the joining groove 3 is compared with the case of using the inclined surface. A large shearing force does not act on the locking projection 11 on the opening side. Moreover, since a pair of wooden joining member 10 is latched by the latching convex part 11 which has a surface parallel to a member longitudinal direction at the wooden member 1 side in the both sides of a groove width direction, rotation of the wooden joining member 10 is carried out. In addition, the peeling stress accompanying the shearing force on the wooden joining member 10 is structured to cancel each other because the directions are different on both sides in the groove width direction. In addition, compared with the structure shown in FIG. 2 (a) (c) (e) or (b) (d) (f), the bonding shown in FIG. 1 (a) (b) (c) (e) (f). In the structure, the shearing force acting on the locking portions in the wooden joining member 10 and the joining groove 3 is smaller, and further, the direction of FIG. The acting bending force can be reduced. In the joining structure of the present invention, the compressive force due to the wedge action acts on the locking portions (the locking convex portions 19 and the engaging convex portions 11) in the wooden joining member 10 and the joining groove 3, Since there is no play in the groove width direction, and the wooden joint member 10 and the wedge device 12 are installed over the entire length of the closing joint hole 9 and the compressive force is acting almost evenly, the member width It has a structure capable of reliably distributing and transmitting stress over the entire length in the direction. As shown in FIG. 35 (b), the wooden joining member 10 is provided with an engaging convex portion 19 having an inclined surface, and the engaging convex portion 19 is coupled with the inclined surface on the engaging groove 14 side. It becomes a form which is easy to guide and fit. In the state of FIG. 35 (b), the pair of wooden joining members 10 is narrowed in the groove width direction and inserted into the closing joint hole 9, and the state immediately before the pair of wooden joining members 10 are widened in the groove width direction. Is shown.

  In the fourth embodiment shown in FIG. 1 (d), the locking groove 14 of the closing bonding hole 9 and the locking projection 19 of the wooden bonding member 10 have a square shape without providing inclined surfaces. Other than the above, the embodiment is the same as the embodiment shown in FIG. By providing an inclined surface when the engaging protrusion 19 is fitted to the engaging groove 14, the engaging protrusion 19 can be easily fitted by the guide action of the inclined surface. FIG. As shown, the bottom of the locking groove 14 and the tip of the locking projection 19 may have a square cross-sectional shape.

  In the fifth embodiment shown in FIG. 1 (e), the width of the joining groove 3 is increased, and the joining groove 3 is symmetrical with respect to the central axis in the direction perpendicular to the groove width direction (or the overlapping surface). A wedge having a pair of wooden wedges 16 disposed between both sides of the joining groove 3 in the groove width direction of the joining groove 3, with the closing joining holes 9 vertically and horizontally symmetrical. By disposing the device 12 and moving the wedge pieces 16 of the wedge device 12 so as to be relatively press-fitted in the longitudinal direction of the groove, the wooden joining members 10 are pressed and moved in the groove width direction, so that the closing joint holes 9 is a joint structure in which the wooden members 1 are joined and integrated by pressing against the inner side wall surface. In the case of this configuration, the wooden joint members 10 on both sides in the groove width direction are members having the same cross-sectional shape, and the processing is facilitated in that the overlapping surface of the wooden joint members 10 is a flat surface. The configuration of the wedge device 12 can also be simplified.

  In the sixth embodiment shown in FIG. 1 (f), the form shown in FIG. 1 (b) is further changed, and the width of the joining groove 3 is increased and the joining groove 3 is arranged in the groove width direction (or superposition). Symmetric with respect to the central axis in the direction perpendicular to the surface), the closing joint holes 9 are vertically symmetric, and the wooden joint members 10 having the form shown in FIG. The wedge device 12 is arranged between them, moved in the groove width direction of each wooden joining member 10, and pressed against the groove inner side wall surface of the closing joining hole 9, so that the wooden members are joined and integrated. It is a junction structure. In order to make it as described above, on both sides of the joining groove 3 in the groove width direction, a groove inner vertical wall surface 13 that is perpendicular to the overlapping surface and flat is provided and a locking groove 14 that is connected thereto is provided. Yes. Further, the other wedge piece 16 in the wedge device 12 is provided with an engaging convex portion 23 continuous in the groove longitudinal direction and stepped portions on both sides of the engaging convex portion 23 as shown in FIG. It is the same as that shown in FIG.

  With reference to Fig.2 (a), FIG.4 (a), and FIG. 13, the joining structure of the wooden member of 7th Embodiment of this invention is demonstrated. The joining groove 3 provided in each wooden member 1 at intervals in the longitudinal direction of the member has a cross-sectional cross section, and the width dimension on the groove back side is larger than the width dimension on the opening side on the surface side where the wooden member 1 is superposed. . The side wall surface inside the groove at one end in the groove width direction of the bonding groove 3 is an inclined side wall surface 25 that is inclined so that the groove width gradually decreases toward the overlapping surface, and the inclined side wall surface 25 is provided. The groove inner side wall surface at the other end in the groove width direction is the groove inner vertical wall surface 13 perpendicular to the overlapping surface, and the inclined side wall surface 25 and the groove inner vertical wall surface 13 are the overlapping surface. The bonding groove 3 is connected to the groove inner bottom surface 15 that is parallel to the groove, and has a width dimension on the groove back side larger than the width dimension on the opening side on the surface side that is overlapped in the cross section. Such a joining groove 3 is provided in the entire width of the wooden member 1 in the plate width direction, and a plurality of wooden members 1 are provided in parallel in the longitudinal direction of the plate so as to face each other. Further, the wooden member 1 is matched so that the joining grooves 3 are arranged symmetrically about the overlapping surface 2. Or it superposes | polymerizes so that the wooden member 1 juxtaposed and the wooden member 1 juxtaposed may be made to oppose. In this way, the wood members 1 are superposed on each other, or the wood members 1 arranged in parallel are superposed on each other to form a closed joint hole 9, and the close joint holes 9 are parallel to each other at intervals. A plurality of them are formed.

The wooden joint member 10 is pressed by the back surface of one wooden wedge piece 16 so that the wooden joint member 10 is pressed against one of the inclined side wall surfaces 25 in the groove width direction, and the other wooden wedge is pressed. Each wooden wedge piece 16 is pushed so that the entire back surface of the piece 16 is pressed against the other groove inner vertical surface 13. If the wooden joint member 10 and the wooden wedge piece 16 are slightly smaller than the groove height dimension of the closing joint hole 9, the insertion work is facilitated, and the long wooden joint member 10 and the wooden wedge piece 16 are used. However, although it becomes easy to insert across the joining grooves 3 of the wooden members 1 arranged in parallel, the dimensions may be almost the same as the height of the grooves of the closing joining holes 9. In this embodiment, since the joining groove 3 includes the inclined side wall surface 25, when the inclined side wall surface 25 is pressed, the wooden members 1 can be positively pressed toward the overlapping surface 2. This is a form in which resistance to peeling force increases when tensile stress acts on the wooden member 1.
