Description

[Technical Field]

[0001] The present invention relates to a structural member connecting structure for connecting one wooden structural member to another structural member. [Background technology]

[0002] Conventionally, a wooden connection structure has been known that includes a beam support metal fitting and a drift pin for connecting a beam, which is a structural material made of wood, to a column, which is also a structural material made of wood (Patent Documents 1 to 3). For example, in a conventional timber connecting structure 1', the base plate 41 of the beam support hardware 4 is fixed to the column 3 with bolts and nuts 7 (see Figures 15(a), (b), and 17(b)). The uppermost drift pin 51 is inserted into the drift pin insertion hole 23 of the beam 2 (see Figures 15(c) and (d)). An insertion plate 42 protruding vertically from the base plate 41 is inserted into a slit 22 formed in the beam 2, and the uppermost drift pin 51 inserted into the drift pin insertion hole 23 of the beam 2 engages with the engagement groove 421 of the insertion plate 42 (see Figures 16(a), (b), and 17(b)). The lower drift pin 52 is then inserted into the drift pin insertion hole 23 formed in the beam 2 and the beam support hardware-side pin hole 422 of the insertion plate 42 (see Figures 16(c), 17(a), and 17(b)). This structure connects the beam 2 to the column 3. The processing of the column 3 and the attachment of the beam support hardware 4 to the column 3, as well as the processing of the beam 2 and the insertion of the top drift pin 51 into the drift pin insertion hole 23, are generally carried out in a pre-cut factory, and at the construction site, the insertion plate 42 of the beam support hardware 4 fixed to the column 3 is inserted into the slit 22 of the beam 2, and the top drift pin 51 engages with the engagement groove 421, supporting the beam 2 on the column 3. In this state, assembly can be completed by inserting the lower drift pin 52 into the drift pin insertion hole 23 of the beam 2 and the beam support hardware side pin hole 422 of the beam support hardware 4, which has the effect of simplifying and facilitating on-site construction.

[0004] However, in the conventional combination of beam support hardware and drift pins, the uppermost drift pin only engaged from above with a pin groove cut into the top of the beam support hardware. Therefore, while the vertical load acting from above the beam could be supported by two drift pins, the upward thrust load acting from below the beam could only be supported by one lower drift pin, resulting in a problem in that the strength to withstand the upward thrust load was inferior to the strength to withstand the vertical load. An example of the upward load acting on this beam is the upward load acting on the beam by the diagonal brace 9 when the structure is deformed by lateral shaking such as an earthquake, in a case where a diagonal brace 9 is installed in a structure consisting of a beam 2 and a column 3 to improve earthquake resistance, as shown in Figure 18. This problem also occurs when there are two or more lower drift pins, and since the number of drift pins required to withstand a thrust load is one less than the number of drift pins required to withstand a vertical load, the strength to withstand a thrust load is inferior to the strength to withstand a vertical load.

[0005] One way to increase the strength against thrust loads is to increase the number of lower drift pins, but this would increase the number of parts in the connecting structure, and the number of holes in the beam support hardware would increase, making the structure more complex and larger, and the cross-sectional size of the beams would also increase, which would increase costs and the number of connecting processes.

[0006] Therefore, the present invention aims to solve the above problems and provide a structural material connection structure that has a simple structure and can improve the resistance to thrust loads applied to beams using parts and processes that are almost the same as conventional structures. [Means for solving the problem]

[0007] In order to solve such problems, the present invention has the following configuration. A structural member connecting structure for connecting one wooden structural member to another structural member, Includes connecting hardware, drift pins and reinforcement plates, The one structural member has a slit and at least two pin insertion holes formed therein, The metal connector has a base plate and at least one insert plate protruding perpendicularly from the base plate, An engagement groove for engaging with a drift pin is formed on one side edge of the insertion plate, At least one metal-side pin hole through which the drift pin is inserted is formed on the other side edge of the insertion plate of the engagement groove, the reinforcing plate is formed with at least two plate-side pin holes through which the drift pins are inserted; A structural material connection structure characterized in that the substrate is fixed to the other structural material, the insertion plate is inserted into the slit, one of the drift pins is inserted into one of the pin insertion holes and one of the plate side pin holes and engaged with the engagement groove, and at least one of the other drift pins is inserted into one of the pin insertion holes, one of the plate side pin holes and one of the metal side pin holes, thereby connecting the one structural material to the other structural material. [Effects of the Invention]

[0008] The present invention can provide a structural member connection structure that has a simple structure and can improve the resistance to thrust loads applied to beams using parts and processes that are almost the same as conventional structures. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] [Embodiment] Hereinafter, a structural member connection structure 1 according to an embodiment of the present invention will be described with reference to the drawings. Note that in this embodiment, a structural member connection structure 1 is described in which a beam 2 made of wood as a structural member is connected to a column 3 made of wood. However, the present invention can be applied to any structural member connection structure that connects one structural member made of wood to another structural member made of wood, such as connecting a beam made of wood to another beam made of wood. Furthermore, the present invention is not limited to a structure in which two structural members are connected perpendicularly, but can also be applied to a structure in which two structural members are connected at an angle. Furthermore, the other structural material is not limited to being made of wood, but may be made of reinforced concrete, steel frame, etc. In other words, the present invention can also be applied to a structure in which a structural material made of wood is connected to a structural material made of reinforced concrete, steel frame, etc. In the following description, the same reference numerals in different drawings indicate parts with the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. For convenience of explanation, terms indicating directions such as up, down, and side are used, but the direction in which gravity acts is down, and the opposite is up.

[0011] [Overall structure] 1 to 3 are diagrams showing the connecting process of a structural member connecting structure 1 according to an embodiment of the present invention. The process progresses in the order of FIGS. 1(a), (c), (d), 2(a), (b), (c), and 3(a). FIG. 1(b) is a view of FIG. 1(a) from a different angle, and FIG. 3(b) is a view of FIG. 3(a) without the beam 2 and column 3. In FIGS. 1 to 3, the heads of the drift pins 5 are hatched to make it easier to distinguish between the drift pin insertion holes 23 and the reinforcing plate-side pin holes 61 and the drift pins 5. The structural material connection structure 1 of this embodiment is a structure for connecting a beam 2 (one structural material) to a column 3 (another structural material), and is a structure for connecting one end of the beam 2 to the side of the upper end of the upright column 3 so that the beam 2 and column 3 are perpendicular to each other, and has a beam support hardware 4 (connecting hardware), a drift pin 5, and a reinforcing plate 6. A beam support hardware 4 is fixed to the side of the upper end of the column 3 with bolts and nuts 7, and the end of the beam 2 is fixed to the beam support hardware 4, thereby connecting the beam 2 and the column 3.

[0012] [Column] The pillar 3 is a long, rod-shaped member made of wood, and is erected vertically on a foundation structure (not shown). A bolt and nut insertion hole 31 is formed on the side of the upper end of the pillar 3, through which a bolt and nut 7 for fixing the beam support hardware 4 is inserted. At the end of the bolt and nut insertion hole 31 on the beam support hardware 4 side, there is a fitting hole into which a round tenon 411 of the beam support hardware 4 (described later) can be fitted, and at the opposite end, there is a fitting hole into which the nut of the bolt and nut 7 can be fitted. The bolt and nut insertion holes 31 and the two fitting holes are processed in a pre-cut factory. In this embodiment, the cross section of the pillar 3 is square, but is not limited to this and may be any shape such as a polygon such as a rectangle, a circle, or an ellipse.

[0013] [Beam] The beam 2 is a long rod-shaped member made of wood, and one end of the beam 2 is connected to the side of the upper end of the pillar 3. On one end face of the beam 2, a shallow groove 21 into which a base plate 41 of the beam support hardware 4 described later fits, and deep slits 22 into which an insertion plate 42 can be inserted are formed on both ends of the groove 21. Further, a drift pin insertion hole 23 (pin insertion hole) through which the drift pin 5 can be inserted is formed so as to be perpendicular to the groove 21 and the two slits 22. The drift pin insertion holes 23 are formed in two locations: one at a position corresponding to the closed side of the engagement groove 421 of the beam support hardware 4 described later, and the other at a position corresponding to one of the beam support hardware side pin holes 422. The inner diameter of the drift pin insertion holes 23 is formed to be approximately the same diameter as the outer diameter of the drift pin 5 described later. The groove 21, the two slits 22, and the two drift pin insertion holes 23 are processed in a pre-cut factory.

[0014] [Beam support hardware (connecting hardware)] FIG. 4 is a diagram showing the metal parts of the structural material connection structure 1 according to the embodiment of the present invention, and (a) to (c) are diagrams showing the beam support metal part 4 (connection metal part). The beam support hardware 4 has a base plate 41 and insertion plates 42 formed by bending both sides of the base plate 41 and protruding perpendicularly from the base plate 41. On the surface of the base plate 41 opposite the surface on which the insertion plate 42 protrudes, a cylindrical tenon 411 is formed at one end in the longitudinal direction of the base plate 41, and an arc-shaped protrusion 412 is formed at the other end. The tenon 411 and the protrusion 412 are arranged parallel to the longitudinal direction of the base plate 41. The inner diameter of the tenon 411 is sized to allow the head of a bolt of the bolt nut 7, which will be described later, to fit therein. The tenon 411 and the protrusion 412 may be arranged so as to be tilted from the longitudinal direction of the base plate 41, or the tenon 411 and the protrusion 412 may be arranged inversely. Neither the tenon 411 nor the protrusion 412 is an essential component, and it is possible to omit either one or both of them.

[0015] Each of the two insertion plates 42 has a notched engagement groove 421 formed in the edge (one side edge) of one end (the same side as the side on which the round tenon 411 of the base plate 41 is formed) in the direction (longitudinal direction) perpendicular to the protruding direction, and two beam support hardware side pin holes 422 (hardware side pin holes) formed side by side on the other end (other side edge). The engagement groove 421 and the two beam support hardware side pin holes 422 are arranged side by side parallel to the longitudinal direction of the insertion plate 42. Note that the engagement groove 421 and the two beam support hardware side pin holes 422 may be arranged so as to be inclined from the longitudinal direction of the insertion plate 42. Furthermore, another engagement groove 421 may be formed on the other end side of the insertion plate 42 in the longitudinal direction. The closed side 4211 of the engagement groove 421 is formed to have an inner diameter that is approximately the same as the outer diameter of the uppermost drift pin 51 so that it can engage with the uppermost drift pin 51 described later, and the open side 4212 is formed to gradually widen from the closed side 4211 to facilitate engagement with the uppermost drift pin 51. Similarly, the inner diameters of the two beam support hardware side pin holes 422 are also formed to have approximately the same dimension as the outer diameter of the lower drift pin 52.

[0016] [Drift Pin] FIG. 4 is a diagram showing the metal parts of the structural material connection structure 1 according to the embodiment of the present invention, and (d) to (e) are diagrams showing the drift pin 5. The drift pin 5 is a metal member that is inserted into the drift pin insertion hole 23 of the beam 2, the engagement groove 421 and the beam support hardware side pin hole 422 of the beam support hardware 4, and the reinforcing plate side pin hole 61 of the reinforcing plate 6 to fix the beam 2 to the beam support hardware 4. In this embodiment, to ensure that the drift pins 5 are securely engaged with the reinforcing-plate-side pin holes 61 of the reinforcing plate 6 described later, a seat-equipped drift pin is used, in which a seat having an outer diameter larger than the outer diameter of the drift pin 5 is formed at one end of the drift pin 5. Note that if the dimensions and shape of the reinforcing plate 6 and the dimensions of the drift pins 5 ensure secure engagement with the reinforcing-plate-side pin holes 61 of the reinforcing plate 6, a drift pin without a seat can also be used. In this embodiment, the same uppermost drift pin 51 and lowermost drift pin 52 are used, but the uppermost drift pin 51 and lowermost drift pin 52 may have different dimensions and shapes.

[0017] [Reinforcement plate] FIG. 4 is a diagram showing the metal parts of the structural material connection structure 1 according to the embodiment of the present invention, and (f) to (g) are diagrams showing the reinforcing plate 6. As shown in FIG. The reinforcing plate 6 is a rectangular metal plate with two reinforcing plate pin holes 61 formed therein. The two reinforcing plate pin holes 61 are formed parallel to each other in the longitudinal direction at one end and the other end of the reinforcing plate 6. In this embodiment, only the lower beam support hardware pin hole 422 of the two beam support hardware pin holes 422 of the beam support hardware 4 is used. Therefore, the two reinforcing plate pin holes 61 are formed so that the spacing between the two reinforcing plate pin holes 61 corresponds to the engagement groove 421 of the beam support hardware 4 and the lower beam support hardware pin hole 422, respectively, and the spacing between the two reinforcing plate pin holes 61 is the same as the spacing between the engagement groove 421 of the beam support hardware 4 and the lower beam support hardware pin hole 422. The inner diameters of the two reinforcing plate pin holes 61 are formed to be approximately the same as the outer diameter of the lower drift pin 52. In addition, a screw hole 62 is formed between the two reinforcing plate side pin holes 61. The reinforcing plate 6 is not limited to being made of metal, but may be made of resin or wood.

[0018] [Structural material connection structure] Figure 3(b) is a diagram showing the beam support hardware 4, drift pin 5, reinforcing plate 6, and bolt nut 7 in the structural material connection structure 1 of an embodiment of the present invention, in a state in which the beam 2 is connected to the column 3 (see Figure 3(a)). The bolt of the bolt nut 7 is inserted into the round tenon 411 of the beam support hardware 4, with the head on one end thereof fitting into the round tenon 411 and a nut fastened to the other end. The two insertion plates 42 of the beam support hardware 4 are inserted into the slits 22 of the beam 2, the uppermost drift pin 51 is inserted into one of the reinforcing plate side pin holes 61 of the reinforcing plate 6 and is engaged with two engagement grooves 421 of the beam support hardware 4, and the lower drift pin 52 is inserted into the other reinforcing plate side pin hole 61 of the reinforcing plate 6 and is inserted into two beam support hardware side pin holes 422 on the lower side of the beam support hardware 4. Note that the screws driven into the screw holes 62 are omitted.

[0019] The vertical load applied to the beam 2 is transmitted to the uppermost drift pin 51 and the lower drift pin 52, and the vertical load transmitted to the uppermost drift pin 51 is transmitted to the engagement groove 421, and the vertical load transmitted to the lower drift pin 52 is transmitted to the pin hole 422 on the beam support hardware side, and is supported by the beam support hardware 4 fixed to the column 3. That is, the vertical load is supported at two points per insertion plate 42 of the beam support hardware 4: the engagement groove 421 and the pin hole 422 on the beam support hardware side. Furthermore, in this embodiment, the uppermost drift pin 51 and the lower drift pin 52 are each connected at one end by a reinforcing plate 6. The upward load applied to the beam 2 is transmitted to the uppermost drift pin 51 and the lower drift pin 52, the upward load transmitted to the uppermost drift pin 51 is transmitted to the lower drift pin 52 via the reinforcing plate 6, and the upward load transmitted to the lower drift pin 52 is combined with the upward load transmitted from the uppermost drift pin 51 and transmitted to the beam support hardware side pin hole 422, and is supported by the beam support hardware 4 fixed to the column 3. That is, the thrust load is supported by the beam support hardware 4 via the uppermost drift pin 51 and the lower drift pin 52.

[0020] In a conventional timber connecting structure 1' (see Figures 15 to 17) without a reinforcing plate 6, the upward load transmitted to the uppermost drift pin 51 is not transmitted to the beam support hardware 4, and only the upward load transmitted to the lower drift pin 52 is supported by the beam support hardware 4. In other words, the upward load is supported only by the lower drift pin 52. In contrast, in this embodiment, the uppermost drift pin 51 and the lower drift pin 52 support the thrust load, and the strength against the thrust load is greatly improved. In this way, in the structural material connection structure 1 of this embodiment, simply by adding the reinforcing plate 6 to the conventional wooden connection structure 1', it is possible to greatly improve the strength against thrust loads.

[0021] [Connection process] The process of connecting a beam 2 and a column 3 will be described with reference to FIGS. 1 to 3, which show the connecting process of a structural member connecting structure 1 according to an embodiment of the present invention. As described above, the bolt and nut insertion hole 31 and two fitting holes are formed in the column 3, and the groove 21, two slits 22, and two drift pin insertion holes 23 are formed in the beam 2 in advance at the pre-cut factory. As shown in Figures 1(a) and (b), the beam support hardware 4 is fixed to the column 3 by a bolt nut 7. If the beam support hardware 4 is fixed to the column 3 only by the bolt nut 7, the beam support hardware 4 may rotate relative to the column 3 around the bolt nut 7 as an axis. In this embodiment, the protrusion 412 of the beam support hardware 4 penetrates into the side of the column 3, preventing the beam support hardware 4 from rotating around the bolt nut 7 as an axis. As shown in Figures 1(c) and (d), the top drift pin 51 is driven through one of the reinforcing plate side pin holes 61 of the reinforcing plate 6 into the upper drift pin insertion hole 23 of the beam 2, and driven until the seat of the top drift pin 51 contacts the outer surface of the reinforcing plate 6, thereby fixing the beam 2 and the reinforcing plate 6. If the beam 2 and the reinforcing plate 6 are fixed only by the uppermost drift pin 51, the reinforcing plate 6 may rotate relative to the beam 2 around the uppermost drift pin 51. In this embodiment, screws (not shown) are driven into the beam 2 through the screw holes 62 in the reinforcing plate 6 to fix the reinforcing plate 6 so that it does not rotate relative to the beam 2. Note that if there is no particular problem with the rotation of the reinforcing plate 6, screw fastening may be omitted. In this case, a reinforcing plate 6 without the screw holes 62 may be used. As described above, the process of fixing the reinforcing plate 6 to the beam 2 and the process of fixing the beam support hardware 4 to the column 3 can also be carried out in advance at the pre-cut factory.

[0022] The beam 2 to which the reinforcing plate 6 is fixed, prepared in the above-mentioned process, is connected to the column 3 to which the beam support hardware 4 is fixed at the construction site. As shown in FIG. 1( d ), the two insertion plates 42 of the beam support hardware 4 are lowered from above the column 3 on which the beam 2 is erected so as to be inserted into the two slits 22 of the beam 2 , respectively. As shown in Figure 2(a), when the end face of the beam 2 is lowered along the side of the column 3, the top drift pin 51 fixed to the beam 2 engages from above with the engagement groove 421 of the beam support hardware 4, and the beam 2 is supported by the beam support hardware 4 fixed to the column 3, as shown in Figure 2(b). In this state, the other reinforcing plate side pin hole 61 of the reinforcing plate 6, the drift pin insertion hole 23 below the beam 2, and the beam support hardware side pin hole 422 below the beam support hardware 4 are concentric. As shown in Figure 2(c), the lower drift pin 52 is driven and inserted from the other reinforcing plate side pin hole 61 of the reinforcing plate 6 into the drift pin insertion hole 23 below the beam 2 and the beam support hardware side pin hole 422 below the beam support hardware 4. Then, as shown in FIG. 3(a), the lower drift pin 52 is driven in until its seat comes into contact with the outer surface of the reinforcing plate 6, thereby fixing the beam 2 and the beam support hardware 4.

[0023] The above steps complete the process of connecting the beam 2 and the column 3. The only difference from the process of connecting the beam 2 and the column 3 in the conventional wooden connecting structure 1' shown in Figures 15 to 17 is that when inserting the drift pin 5 into the drift pin insertion hole 23 of the beam 2, it is inserted by aligning it with the reinforcing plate side pin hole 61 of the reinforcing plate 6, and, if necessary, the reinforcing plate 6 is fastened to the beam 2 with a screw. As such, the process of connecting the beam 2 and the column 3 in this embodiment is almost the same as the process of connecting the beam 2 and the column 3 in the conventional wooden connection structure 1', and the number of steps in the connection work is only slightly increased, making it almost the same.

[0024] [Modifications of the reinforcing plate (Modifications 1, 2, and 3)] 5A to 5F are diagrams showing modified examples of the reinforcing plate 6, with (a) to (c) showing modified example 1 and (d) to (f) showing modified example 2. In FIG. FIG. 6 shows a third modified example, in which (a) to (c) show a reinforcing plate 6a3, and (d) shows an example of its use. As described above, the reinforcing plate 6 of the embodiment has a screw hole 62 formed therein, and after the top drift pin 51 is inserted from one of the reinforcing plate side pin holes 61 of the reinforcing plate 6 to the drift pin insertion hole 23 on the upper side of the beam 2, a screw is driven into the beam 2 through the screw hole 62 of the reinforcing plate 6 to prevent the reinforcing plate 6 from rotating relative to the beam 2 around the top drift pin 51 as its axis. Instead of fixing the reinforcing plate 6 to the beam 2 with this screw, a protrusion that penetrates into the beam 2 can be formed on one side of the reinforcing plate 6, and when the reinforcing plate 6 is fixed to the beam 2 with the uppermost drift pin 51, the protrusion penetrates into the beam 2, thereby fixing the plate.

[0025] In variant 1, the reinforcing plate 6a1 is punched out into a mountain shape using a press, and a triangular protrusion 63 is formed on one side of the reinforcing plate 6a1. When the top drift pin 51 is driven into the beam 2, the reinforcing plate 6a1 abuts against the side of the beam 2, and the protrusion 63 penetrates into the beam 2 from one vertex of the triangle, fixing the reinforcing plate 6a1 to the beam 2 so that it does not rotate around the top drift pin 51. In variant 2, the reinforcing plate 6a2 is punched out into a circular shape using a press, and a circumferential protrusion 64 is formed on one surface of the reinforcing plate 6. When the uppermost drift pin 51 is driven into the beam 2, the reinforcing plate 6a2 comes into contact with the side surface of the beam 2, and the protrusion 64 penetrates into the beam 2 from the tip of the circumferential shape, and the reinforcing plate 6a2 is fixed to the beam 2 so that it does not rotate around the uppermost drift pin 51. In these modified examples 1 and 2, there is no need to fasten the reinforcing plates 6a1 and 6a2 with screws, and the reinforcing plates 6a1 and 6a2 can be fixed to the beam 2 more easily.

[0026] In the third modification, as shown in FIGS. 6(a) to 6(c), the reinforcing plate 6a3 has a locking piece 65 formed by bending one end in the longitudinal direction thereof. As shown in FIG. 6(d), the locking piece 65 is formed so as to be locked to the upper surface of the beam 2 when the reinforcing plate 6a3 is fixed to the beam 2. When the reinforcing plate 6a3 is attached to the beam 2 using the uppermost drift pin 51, the locking piece 65 can be hooked onto the upper surface of the beam 2, thereby aligning the position of the pin hole 61 on the reinforcing plate with the position of the drift pin insertion hole 23, improving workability. Furthermore, by locking the locking piece 65 to the beam 2, after the reinforcing plate 6a3 is fixed to the beam 2 by the uppermost drift pin 51, it is prevented from rotating relative to the beam 2 around the uppermost drift pin 51 as an axis. The length of the reinforcing plate 6a3 and the arrangement of the pin holes 61 on the reinforcing plate side are such that when the reinforcing plate 6a3 is used in the structural material connection structure 1 with the drift pins 51 and 52, they match the upper surface of the beam and the position of the drift pin insertion holes 23, respectively. The locking piece 65 may be locked to the lower surface of the beam 2 instead of the upper surface.

[0027] [Modification of Drift Pin (Modification 4)] FIG. 7 shows a fourth modification in which the drift pin 5 of the embodiment is replaced with a bolt nut 8. In FIG. The two drift pins 5 of the embodiment are changed to two bolts and nuts 8. Furthermore, reinforcing plates 6 are arranged on both ends of the bolts and nuts 8, and a total of two reinforcing plates 6 are used. In this fourth modification, the uppermost bolt nut 81 and the lower bolt nut 82 are connected by two reinforcing plates 6. Therefore, the thrust force received by the uppermost bolt nut 81 is transmitted to the lower bolt nut 82 by the two reinforcing plates 6, further improving the resistance to the thrust load. In addition, because the reinforcing plates 6 are arranged on both sides of the beam 2 in the width direction, the moment around the axis perpendicular to the base plate 41 of the beam support hardware 4 can be reduced when transmitting the thrust load. Although two reinforcing plates 6 are used in this variant example 4, it is also possible to use a reinforcing plate 6 only on one end of the bolt nut 8, and abut the other end of the bolt nut directly against the beam 2 or abut it via a washer, i.e., to use only one reinforcing plate 6. In this fourth modification, the same bolt nut 81 and the same lower bolt nut 82 are used, but the uppermost bolt nut 81 and the lower bolt nut 82 may have different dimensions and shapes.

[0028] [Modification of beam support hardware (Modification 5)] FIG. 8 is a diagram showing a beam support hardware 4a which is a modified example of the beam support hardware 4 according to the embodiment of the present invention. The beam support hardware 4 of the embodiment has two insertion plates 42 formed by bending both side portions of a base plate 41 and protruding perpendicularly from the base plate 41. In the beam support hardware 4a (connecting hardware) of this modified example 5, the number of insertion plates 42 has been changed to one. That is, one insertion plate 42 extending in the longitudinal direction of the base plate 41 is provided at the center of the short side of the base plate 41 so as to protrude perpendicularly from the base plate 41. One slit is formed in the beam 2, into which one insertion plate 42 is inserted. The structure of the insertion plate 42 is the same as that of the insertion plate 42 of the embodiment. In the beam support hardware 4a of the fourth modification, the insertion plate 42 is provided at the center of the base plate 41 in the short direction, so it is difficult to form an insertion hole in the base plate 41 through which the bolt nut 7 is inserted. Therefore, in the beam support hardware 4a, a round tenon 411a is provided on one end of the longitudinal direction of the base plate 41, on the side opposite to the side on which the insertion plate 42 of the base plate 41 is protruded, and a female screw is formed on the inner surface of this round tenon 411a. That is, the beam support hardware 4a is fixed to the pillar 3 by a screw inserted through a screw insertion hole (similar to the bolt and nut insertion hole 31 in the embodiment) formed on the side surface of the upper end of the pillar 3. The beam support hardware 4a of this modified example 5 is fixed to the column 3 with a screw, so it is almost impossible for the beam support hardware 4 to rotate around the screw axis relative to the column 3 even after being fixed. For this reason, the beam support hardware 4a does not have a protrusion like the protrusion 412 of the beam support hardware 4 of the embodiment. However, it is possible to form a similar protrusion on the beam support hardware 4a of this modified example 5. In this modification 5, the strength against thrust loads can be greatly improved simply by adding a reinforcing plate to a conventional wooden connection structure using one insert plate.

[0029] [Modification of structural material connection structure (Modification 6)] FIG. 9 is a diagram showing a modified example of the structural material connecting structure 1 of the present invention, in which (a) to (c) show a beam support metal fitting 4b, and (d) to (e) show a reinforcing plate 6b. In this variant example 6, when the beam size is large or the load applied to the beam is large, two lower drift pins 52 are used and both lower drift pins 52 are inserted into the beam support hardware 4b.

[0030] The beam support hardware 4b, like the beam support hardware 4 of the embodiment, has a base plate 41b and insertion plates 42b formed by bending both sides of the base plate 41b and protruding perpendicularly from the base plate 41b. Similar to the insert plate 42 of the embodiment, each of the two insertion plates 42b has an engagement groove 421b cut out at one longitudinal edge, and four beam support hardware side pin holes 422 (metal-side pin holes) arranged side by side at the other edge. In this modification 6, the upper three of the four beam support hardware side pin holes 422b are arranged at equal intervals, and the lower one is arranged slightly away. In this modification 5, only the middle beam support hardware side pin hole 422b and the lower one of the upper three beam support hardware side pin holes 422b are used. Note that either of the other two beam support hardware side pin holes 422b may be used, and the arrangement of the beam support hardware side pin holes 422b can be appropriately modified. Furthermore, a configuration using three or more lower drift pins 52 is also possible.

[0031] The reinforcing plate 6b is a rectangular metal plate with three reinforcing plate pin holes 61b formed in it. The three reinforcing plate pin holes 61b are aligned parallel to the longitudinal direction of the reinforcing plate 6b. In this modification 6, only the middle beam support hardware pin hole 422b and the lower beam support hardware pin hole 422b out of the four beam support hardware pin holes 422b of the beam support hardware 4b are used, so the three reinforcing plate pin holes 61b are arranged to correspond to the engagement grooves 421b and two beam support hardware pin holes 422b of the beam support hardware 4b, respectively. Furthermore, a screw hole 62b for fixing the reinforcing plate 6b to the beam 2 is formed between the two reinforcing plate side pin holes 61b.

[0032] In this sixth modification, because the load on the beam 2 is large, two bolts and nuts 7 are used to secure the beam support hardware 4b to the column 3. Therefore, the tenons 411b are also formed in two places. Depending on the load on the beam 2, it is also possible to form one tenon and one protrusion, and secure the reinforcing plate 6b to the beam 2 with one bolt and nut 7, as in the embodiment.

[0033] The vertical load applied to the beam 2 is transmitted to the top drift pin 51 and the two lower drift pins 52, and the vertical load transmitted to the top drift pin 51 is transmitted to the engagement groove 421b, and the vertical load transmitted to the lower drift pins 52 is transmitted to the pin hole 422b on the beam support hardware side, and is supported by the beam support hardware 4b fixed to the column 3. That is, the vertical load is supported at three points per insertion plate 42b of the beam support hardware 4b: the engagement groove 421b and the two beam support hardware side pin holes 422b. Furthermore, in this modified example 6, the uppermost drift pin 51 and the two lower drift pins 52 are each connected at one end by a reinforcing plate 6b. The upward load applied to the beam 2 is transmitted to the uppermost drift pin 51 and the two lower drift pins 52, the upward load transmitted to the uppermost drift pin 51 is transmitted to the two lower drift pins 52 via the reinforcing plate 6b, and the upward load transmitted to the two lower drift pins 52, together with the upward load transmitted from the uppermost drift pin 51, is transmitted to the two beam support hardware side pin holes 422b and is supported by the beam support hardware 4b fixed to the column 3. That is, the thrust load is supported by the beam support hardware 4b via the uppermost drift pin 51 and the two lower drift pins 52. In this sixth modification, too, the strength against thrust loads can be significantly improved simply by adding a reinforcing plate to a conventional wooden connection structure using two lower drift pins.

[0034] [Modification of structural material connection structure (Modification 7)] 10A and 10B are diagrams showing a structural material connection structure 1 which is a modified example of the structural material connection structure 1 of the present invention, where (a) is a diagram seen from above, (b) is a diagram seen from a side, and (c) is a diagram showing a reinforcing plate 6c. In Fig. 10, the head of the drift pin 5 is hatched to make it easier to distinguish the drift pin 5 from the beam support hardware side pin hole 422c and the reinforcing plate side pin hole 61c. In the seventh modified example, the beam support metal fitting 4c and the reinforcing plate 6c are different from those of the embodiment. The beam support hardware 4c, like the beam support hardware 4 of the embodiment, has a base plate 41c and insertion plates 42c formed by bending both sides of the base plate 41c and protruding perpendicularly to the base plate 41c. Each of the two insertion plates 42c has a notched engagement groove 421c formed on both one and the other longitudinal edge. This configuration allows the beam support hardware 4c to be used upside down. In addition, three beam support hardware side pin holes 422c (metal side pin holes) are formed at equal intervals at a position off the line connecting the two engagement grooves 421c. In this modification example 7, only the engagement groove 421c on one side edge of the two engagement grooves 421c and the lowest beam support hardware side pin hole 422c of the three beam support hardware side pin holes 422c are used. Note that either of the other two beam support hardware side pin holes 422c may be used, and the arrangement of the beam support hardware side pin holes 422c can be modified as appropriate. It is also possible to configure the structure to use two or more lower drift pins 52.

[0035] The reinforcing plate 6c is a rectangular metal plate with two reinforcing plate pin holes 61c formed in it. The two reinforcing plate pin holes 61c are formed at the diagonal upper and lower ends of the reinforcing plate 6c. In this seventh modification, only the engagement groove 421c on one side edge of the beam support hardware 4c and the beam support hardware pin hole 422c at the bottom are used, so the two reinforcing plate pin holes 61c are arranged to correspond to the engagement groove 421c on one side edge and the beam support hardware pin hole 422c at the bottom, respectively. In other words, the distance between the two reinforcing plate pin holes 61c is equal to the distance between the engagement groove 421c on one side edge and the beam support hardware pin hole 422c at the bottom. Furthermore, a screw hole 62c for fixing the reinforcing plate 6c to the beam 2 is formed between the two reinforcing plate side pin holes 61c.

[0036] In this modified example 7, two bolts and nuts 7 are used to fix the beam support hardware 4c to the column 3. Therefore, two bolt and nut insertion holes are formed in the base plate 41c. Also, although the beam support hardware 4c does not have a round tenon, a round tenon can be formed as in the embodiment. In this seventh modification, the strength against thrust loads can be significantly improved simply by adding the reinforcing plate 6c to the conventional wooden connection structure.

[0037] [Modification of structural material connection structure (Modification 8)] 11 is a diagram showing a structural material connection structure 1 which is a modified example of the structural material connection structure 1 of the present invention, where (a) is a diagram seen from above, (b) is a diagram seen from the side, (c) is a diagram showing reinforcing plate 6, and (d) and (e) are diagrams showing an example in which reinforcing plate 6d is used instead. In FIG. 11, the head of drift pin 5 is hatched to make it easier to distinguish between beam support hardware side pin hole 422c and reinforcing plate side pin holes 61 and 61d and drift pin 5. The eighth modification is different from the seventh modification in the reinforcing plate, but other configurations are the same as those of the seventh modification. In the present modified example 8, only the engagement groove 421c on one side edge and the central beam support hardware side pin hole 422c out of the three beam support hardware side pin holes 422c are used.

[0038] 11(a) to 11(c), the reinforcing plate 6 used in the embodiment is used as the reinforcing plate, but the engagement groove 421c on one side edge and the beam support hardware side pin hole 422c are arranged at an angle rather than parallel to the longitudinal direction of the insertion plate 42c, so the reinforcing plate 6 is also used at an angle. In addition, the two reinforcing plate side pin holes 61 are arranged to correspond to the engagement groove 421c on one side edge and the beam support hardware side pin hole 422c in the center, respectively. In other words, the distance between the two reinforcing plate side pin holes 61 is formed equal to the distance between the engagement groove 421c on one side edge and the beam support hardware side pin hole 422c in the center.

[0039] As shown in FIGS. 11(d) to (e), reinforcing plates 6d of different shapes can also be used. The reinforcing plate 6d is a rectangular metal plate with two reinforcing plate pin holes 61d formed in it. The two reinforcing plate pin holes 61d are formed at the diagonal upper and lower ends of the reinforcing plate 6d. In this modification 8, only the engagement groove 421c on one side edge and the central beam support hardware pin hole 422c are used, so the two reinforcing plate pin holes 61d are positioned to correspond to the engagement groove 421c on one side edge and the central beam support hardware pin hole 422c, respectively. Furthermore, a screw hole 62d for fixing the reinforcing plate 6d to the beam 2 is formed between the two reinforcing plate side pin holes 61d. That is, the distance between the two reinforcing plate side pin holes 61d is equal to the distance between the engagement groove 421c on one side edge and the beam support hardware side pin hole 422c in the center. In the present modified example 8, the strength against the thrust load can be greatly improved simply by adding the reinforcing plate 6 or the reinforcing plate 6d to the conventional wooden connecting structure.

[0040] [Modification of structural material connection structure (Modification 9)] Figure 12 shows a structural material connection structure 1 which is a modified example of the structural material connection structure 1 of the present invention, where (a) is a diagram showing a state in which a beam 2 is connected to a column 3, and (b) is a diagram showing a beam support hardware 4, drift pin 5, reinforcing plate 6e, and bolt nut 7 when the beam 2 is connected to the column 3. In this modification 9, the beam support hardware 4, drift pins 5, and bolt nuts 7 are the same as those in the embodiment. Note that three drift pins are used as the drift pins 5: an uppermost drift pin 51, a lower drift pin 52, and an additional drift pin 53. Similar to the reinforcing plate 6b of the sixth modification, the reinforcing plate 6e of the ninth modification is a rectangular metal plate with three reinforcing plate pin holes formed therein. The three reinforcing plate pin holes are aligned parallel to the longitudinal direction of the reinforcing plate 6e, from one end to the other. In the ninth modification, only the beam support hardware pin hole 422 of the two beam support hardware pin holes 422 of the beam support hardware 4 is used. Therefore, the reinforcing plate pin hole at one end of the three reinforcing plate pin holes and the middle reinforcing plate pin hole are positioned to correspond to the engagement groove 421 of the beam support hardware 4 and the lower beam support hardware pin hole 422, respectively. The reinforcing plate pin hole at the other end of the three reinforcing plate pin holes is positioned away from the middle reinforcing plate pin hole toward the other end so as to correspond to an area where the beam support hardware 4 is not present. Furthermore, a screw hole 62e for fixing the reinforcing plate 6e to the beam 2 is formed between the two upper reinforcing plate side pin holes.

[0041] The bolt of the bolt nut 7 is inserted into the tenon 411 of the beam support hardware 4, with the head on one end thereof fitting into the tenon 411 and a nut fastened to the other end. The uppermost drift pin 51 is inserted into the reinforcing plate side pin hole on one end side of the reinforcing plate 6e and engages with two engagement grooves 421 of the beam support hardware 4, and the lower drift pin 52 is inserted into the reinforcing plate side pin hole in the middle of the reinforcing plate 6c and into the beam support hardware side pin hole 422 on the lower side of the beam support hardware 4. The uppermost drift pin 51 and the lower drift pin 52 are inserted into drift pin insertion holes 23 formed in the beam 2. The additional drift pin 53 is inserted into the reinforcing plate side pin hole on the other end side of the reinforcing plate 6e and into the drift pin insertion hole 23 formed in the beam 2, but is not inserted into the beam support hardware side pin hole 422 of the beam support hardware 4. The screw driven into the screw hole 62e is omitted.

[0042] In the present modified example 9, the uppermost drift pin 51, the lower drift pin 52, and the additional drift pin 53 are each connected at one end by a reinforcing plate 6e. The vertical load applied to the beam 2 is transmitted to the uppermost drift pin 51, the lower drift pin 52, and the additional drift pin 53; the vertical load transmitted to the uppermost drift pin 51 is transmitted to the engagement groove 421; the vertical load transmitted to the lower drift pin 52 is transmitted directly to the pin hole 422 on the beam support hardware side; and the vertical load transmitted to the additional drift pin 53 is transmitted to the uppermost drift pin 51 and the lower drift pin 52 via the reinforcing plate 6c, and is supported by the beam support hardware 4 fixed to the column 3. The upward load applied to the beam 2 is transmitted to the uppermost drift pin 51, the lower drift pin 52, and the additional drift pin 53, and the upward load transmitted to the uppermost drift pin 51 and the load transmitted to the additional drift pin 53 are transmitted to the lower drift pin 52 via the reinforcing plate 6e, and the load transmitted to the lower drift pin 52, together with the upward load transmitted from the uppermost drift pin 51 and the upward load transmitted from the additional drift pin 53, is transmitted to the beam support hardware side pin hole 422 and is supported by the beam support hardware 4 fixed to the column 3. That is, the thrust load is supported by the beam support hardware 4 via the uppermost drift pin 51, the lower drift pin 52, and the additional drift pin 53. In the eighth modified example, the strength against the thrust load can be significantly improved simply by adding the reinforcing plate 6e and the additional drift pin 53 to the conventional wooden connecting structure 1'. Furthermore, in the present modified example 9, the strength against vertical loads can be greatly improved compared to the conventional wooden connecting structure 1'.

[0043] [Modification of structural material connection structure (Modification 10)] Figure 13 shows a structural material connection structure 1 which is a modified example of the structural material connection structure 1 of the present invention, where (a) is a diagram showing a state in which a beam 2 is connected to a column 3, and (b) is a diagram showing a beam support hardware 4, drift pin 5, reinforcing plate 6, and bolt nut 7 when the beam 2 is connected to the column 3. In this modified example 10, the beam support hardware 4, drift pin 5, reinforcing plate 6, and bolt nut 7 are the same as those in the embodiment. The tenth modification differs from the embodiment in the arrangement of the reinforcing plate 6. In the embodiment, the reinforcing plate 6 is disposed on the outer surface of the beam 2 , but in the tenth modification, the reinforcing plate 6 is disposed in a slit 22 formed in the beam 2 . The reinforcing plate 6 is inserted into one of the slits 22 together with one of the insertion plates 42 of the beam support hardware 4. Therefore, one of the slits 22 into which the reinforcing plate 6 is inserted is formed to have a thickness greater than that of the other slit 22 .

[0044] The reinforcing plate 6 used in this modified example 10 does not need to have screw holes 62, and it is possible to use a reinforcing plate without screw holes 62. In addition, it is not necessary to use drift pins with seats, and it is sufficient to use drift pins without seats. In this modified example 10, simply by adding a reinforcing plate 6 to the conventional wooden connecting structure 1', it is possible to greatly improve the strength against the thrust load. In addition, in this variant example 10, the reinforcing plate 6 is stored inside the beam 2 and is not visible from the outside, so it does not detract from the aesthetic appearance.Furthermore, since the reinforcing plate 6 is positioned near the center of the width of the beam 2, the moment around the axis perpendicular to the base plate 41 of the beam support hardware 4 can be reduced when transmitting the thrust load. It is also possible to use two reinforcing plates 6, in which case a reinforcing plate 6 is placed in both of the two slits 22. In this case, the strength against the thrust load can be improved more than when one reinforcing plate 6 is used, and the moment that tends to rotate the beam support hardware 4 can be reduced.

[0045] [Modification of structural material connection structure (Modification 11)] 14A to 14C are diagrams showing a structural material connection structure 1 which is a modified example of the structural material connection structure 1 of the present invention, in which (a) is a diagram showing a state in which a beam support hardware 4 is attached to a column 3, (b) is a diagram showing a state in which a reinforcing plate 6f is attached to a beam 2, (c) is a diagram showing a state in which the beam 2 is connected to the column 3, and (d) is a diagram showing the beam support hardware 4, drift pin 5, reinforcing plate 6f, and bolt nut 7 in a state in which the beam 2 is connected to the column 3. In addition, in Figs. 14A to 14C, the head of the drift pin 5 is hatched to make it easy to distinguish between the drift pin insertion hole 23, the reinforcing plate side pin hole 61f, and the drift pin 5. The eleventh modification differs from the tenth modification in the reinforcing plate 6f. In this modification 11, similarly to modification 10, the reinforcing plate 6f is inserted into the slit 22 formed in the beam 2 together with the insertion plate 42 of the beam support hardware 4. The reinforcing plate 6f used in this modified example 11 is characterized in that two reinforcing plates 6 of modified example 10 are joined together to form one member. The reinforcing plate 6f is formed by bending a single metal plate at two locations, and has a substantially U-shape with two reinforcing portions 6f1 connected by a connecting portion 6f2. Each of the two reinforcing portions 6f1 has reinforcing plate side pin holes 61f formed at two locations.

[0046] As shown in FIGS. 14(a) and 14(b), the two reinforcing portions 6f1 of the reinforcing plate 6f are inserted into the slits 22 of the beam 2, and the top drift pin 51 is inserted into the drift pin insertion hole 23 of the beam 2 and the two reinforcing plate-side pin holes 61f of the reinforcing plate 6f to fix the reinforcing portion 6f1 to the beam 2. At this time, the connection portion 6f2 of the reinforcing portion 6f1 abuts against the upper surface of the beam 2, preventing the reinforcing portion 6f1 from rotating relative to the beam 2 around the top drift pin 51. In addition, simply inserting the reinforcing plate 6f, which is formed in a substantially U-shape, between the two slits 22 of the beam 2 makes it easy to position the two reinforcing portions 6f1 in the slits 22 and to align the positions of the two reinforcing plate-side pin holes 61f with the positions of the drift pin insertion holes 23, thereby improving workability compared to the tenth modification. Then, the two insertion plates 42 of the beam support hardware 4 are inserted into the slits 22, and the uppermost drift pin 51 is engaged with the engagement groove 421 of the beam support hardware 4, thereby supporting the beam 2 on the column 3. In this state, as shown in Figure 14(c), the lower drift pin 52 is inserted through the drift pin insertion hole 23, the reinforcing plate side pin hole 61f, and the beam support hardware side pin hole 422, thereby connecting the beam 2 to the column 3.

[0047] In this modification 11, the reinforcing plate 6f used does not need to have screw holes, and there is no need to use drift pins with seats; drift pins without seats are sufficient. In this modification 11, simply by adding the reinforcing plate 6f to the conventional wooden connecting structure 1', it is possible to greatly improve the strength against the thrust load. Furthermore, in this variant example 11, the reinforcing plate 6f is stored inside the beam 2 and is not visible from the outside, so it does not detract from the aesthetic appearance.Furthermore, the two reinforcing portions 6f1 of the reinforcing plate 6f are positioned on either side of the center of the beam 2 in the width direction, so when transmitting the thrust load, the moment around the axis perpendicular to the base plate 41 of the beam support hardware 4 can be made extremely small.

[0048] As described above, the embodiment and its modifications 1 to 11 according to the present invention have been described in detail with reference to the drawings, but the specific configurations are not limited to these embodiments and modifications, and the present invention also includes design changes and the like that do not deviate from the gist of the present invention. Furthermore, the above-described embodiment and modifications can be combined by utilizing each other's technologies as long as there are no particular contradictions or problems in their purposes, configurations, etc. [Explanation of symbols]
