[0004] However, conventional metal joints, including the invention described in Patent Document 1, are attached to the side of columns to join beams. Therefore, when attempting to join long beams, the weight of the beams generates a large shear force at the joint, which may damage the columns. Therefore, conventional metal joints cannot increase the distance (span) between columns, making it difficult to build large wooden buildings.

[0018] As shown in Fig. 1, the beam support hardware 1 according to the present invention is for placing and joining a beam 12 to the upper end of a column 11 that constitutes a wooden building 10. Hereinafter, an embodiment of the beam support hardware 1 according to the present invention, a wooden building 10 using the same, and a wooden building construction method will be described.

[0019] The beam support hardware 1A of the first embodiment is made of high-strength steel plate or the like, and as shown in Figures 1 and 2, has a beam support plate 2 on which one ends of a plurality of beams 12 are placed, a pair of beam connection plates 3 standing up from the beam support plate 2, and a pair of column connection plates 4 hanging down from the beam support plate 2. Each component will be described below.

[0020] The beam mounting plate 2 is provided for mounting one end of the beam 12 that is hung from a plurality of directions on the column 11. In the first embodiment, the beam mounting plate 2 has a column-beam joint 21 interposed between the upper end surface of the column 11 and the lower surface of the beam 12, and a beam load distribution portion 22 that distributes and supports the load of the beam 12, as shown in Fig. 3. The beam mounting plate 2 is formed in a rectangular shape having the beam load distribution portions 22 at both end edges of the column-beam joint 21.

[0021] In the first embodiment, the column-beam joint 21 has a column abutment surface 211 on the lower side that abuts on the upper end surface of the column 11, and a beam end support surface 212 that supports the end of the beam 12 on the upper side of the column abutment surface 211. In addition, the beam load distribution portion 22 extends from the column-beam joint 21 along the longitudinal direction of the beam 12 with the same width, and its upper surface is formed flush with the beam end support surface 212.

[0022] The shape of the beam support plate 2 and the arrangement of the beam load distribution portion 22 are not limited to the above configuration, but may be any plate having an area larger than the upper end surface of the column 11, placed on the upper end surface of the column 11, and having one end of a plurality of beams 12 placed on its upper surface.

[0023] The beam joint plate 3 is joined to both side surfaces of one end of the beam 12 placed on the beam support plate 2. In the first embodiment, as shown in Fig. 1 and Fig. 2, the beam joint plate 3 is raised upward in the substantially vertical direction from a pair of long sides of the beam support plate 2 with a width substantially equal to the long sides, and is joined to each of the both side surfaces of one end of the beam 12.

[0024] The column joint plate 4 is joined to both side surfaces of the upper end of the column 11 on which the beam 12 is to be placed. In this first embodiment, as shown in Fig. 1 and Fig. 2, the column joint plate 4 hangs down substantially vertically from a pair of long sides of the beam placement plate 2 with substantially the same width as the column 11, and is joined to each of the both side surfaces of the upper end of the column 11.

[0025] In this first embodiment, the column joint plate 4 and the beam joint plate 3 are formed into a generally T-shape as a whole, as shown in Figures 1 to 3. The column joint plate 4 and the beam joint plate 3 are provided with a plurality of screw holes H in both the generally horizontal and generally vertical directions for fastening to the column 11 and the beam 12, respectively, with screws B. The screws B are thinner and smaller than a typical bolt, and are formed in a rod shape with a pointed tip, with a thread provided on the outer surface.

[0026] In the first embodiment, the beam support hardware 1A is for connecting beams 12 facing each other in a straight line as shown in Fig. 1. For this reason, a group of screw holes H for connecting to each beam 12 is provided on the left and right positions of the beam connecting plate 3. Note that the shape of the beam connecting plate 3 and the arrangement of the screw holes H are not limited to the above configuration, and may be changed as appropriate as long as the effects of the present invention are achieved.

[0027] Next, the operation of the beam support hardware 1A according to the present invention, the wooden building 10 using the same, and the wooden building construction method will be described.

[0028] When constructing a wooden building 10 using the beam support hardware 1A of the first embodiment, first, the beam support hardware 1A is placed on the upper end of the column 11, and a pair of column joint plates 4 are joined to both sides of the upper end of the column 11 (column joint plate joining process). As a result, the pair of column joint plates 4 fix and integrate the beam support hardware 1A to the upper end of the column 11, so that the beam 12 can be placed on the beam placement plate 2.

[0029] 1, one end of each beam 12 is placed on the upper surface of the beam mounting plate 2, and a pair of beam connecting plates 3 are joined to both side surfaces of one end of each beam 12 (beam connecting plate joining process). As a result, the pair of beam connecting plates 3 are fixed to one end of each beam 12 and integrated, so that each beam 12 is joined in a state in which it is placed on the upper end of the column 11. Note that, in this first embodiment, two beams 12 are used overlapping horizontally, but the present invention is not limited to this configuration, and one beam or three or more beams may be overlapped.

[0030] At this time, in the first embodiment, the column abutment surface 211 of the column-beam joint 21 abuts on the upper end surface of the column 11, and the beam end support surface 212 supports the end of each beam 12. Therefore, the column-beam joint 21 directly transmits the load of each beam 12 to the upper end surface of the column 11. In addition, the beam load distribution portion 22 expands the mounting area of ​​the beam mounting plate 2 beyond the upper end surface of the column 11 to distribute the load of the beam 12, thereby reducing the load on the upper end surface of the column 11. Therefore, even if a long beam 12 is joined, the column 11 is not damaged, and it is possible to increase the size of the wooden building 10.

[0031] In addition, in the first embodiment, the beam support hardware 1A is fixed to the columns 11 and beams 12 by screwing screws B into a plurality of screw holes H provided in the column joint plate 4 and the beam joint plate 3. Therefore, compared to the conventional case of fixing with thick bolts, there is no need to drill large holes in the columns 11 and beams 12, and the beam support hardware 1A is firmly fixed without placing a large burden on the columns 11 and beams 12.

[0032] According to the beam support hardware 1A of the first embodiment and the wooden building construction method using the same, beams 12 of the same width facing each other can be joined in a straight line, as shown in Fig. 1. Also, as shown in Fig. 1, joints 14 such as dovetail joints can be provided on both sides of the joined beams 12, and auxiliary beams 13 can be joined in the perpendicular direction. This makes it possible to construct a wooden building 10 in which beams 12 and auxiliary beams 13 are hung from four directions over a long span from one column 11, as shown in part A of Fig. 4. Note that other beams 12 and auxiliary beams 13 that are not directly hung on the column 11 are omitted in Fig. 4.

[0033] According to the first embodiment of the beam support hardware 1A according to the present invention, the wooden building 10 using the same, and the wooden building construction method, the following effects are achieved. 1. By placing the beams 12 on the upper ends of the columns 11 to distribute the load, it is possible to join long beams 12 without damaging the columns 11, and to construct a large wooden building 10. 2. The ends of the beams 12 are supported by the upper end surfaces of the columns 11, and the load of the beams 12 placed on them is distributed, thereby reducing the load on the columns 11. 3. Beams 12 of the same width facing each other can be joined in a straight line to the columns 11 that make up the wooden building 10. 4. The beam support hardware 1A can be firmly fixed without placing a large burden on the columns 11 and beams 12.

[0034] Next, a second embodiment of the beam support hardware 1B according to the present invention and a wooden building 10 and a wooden construction method using the same will be described. Note that, among the components of the second embodiment, components that are the same as or correspond to those of the first embodiment described above will be given the same reference numerals and will not be described again.

[0035] The characteristic of the beam support hardware 1B of the second embodiment is that, as shown in Figure 5, it joins a beam 12 that is suspended from one direction to a column 11 that constitutes a wooden building 10, and an auxiliary beam 13 that is suspended perpendicular to both sides of the beam 12.

[0036] In the second embodiment, as shown in Fig. 6, the beam mounting plate 2 is formed in a rectangular shape having a beam load distribution portion 22 at one end edge of the column-beam joint portion 21. Moreover, an auxiliary beam recess 31 for joining the auxiliary beam 13 in a direction perpendicular to the side surface of the beam 12 placed on the beam mounting plate 2 is provided at the other end edge side of the column-beam joint portion 21 in the beam mounting plate 3. Furthermore, the column joint plate 4 hangs down substantially vertically downward from the column-beam joint portion 21 in the beam mounting plate 2 with substantially the same width as the column 11.

[0037] When constructing a wooden building 10 using the beam support hardware 1B of the second embodiment, first, the beam support hardware 1B is placed on the upper end of the column 11, and a pair of column joint plates 4 are joined to both sides of the upper end of the column 11 (column joint plate joining process). As a result, the pair of column joint plates 4 are fixed to the upper end of the column 11 and integrated, so that the beam 12 can be placed on the beam support plate 2.

[0038] Next, as shown in FIG. 5, the pair of auxiliary beams 13 facing each other are placed on the beam mounting plate 2 with their ends protruding from the auxiliary beam recess 31 toward the column-beam joint 21 side, and then one end of the beam 12 is placed on the upper surface of the beam mounting plate 2, and a pair of beam joint plates 3 are joined to both sides of the beam mounting plate 2 (beam joint plate joining process). At this time, as shown in FIG. 5, grooves 121 into which the ends of the auxiliary beams 13 are inserted are formed on both sides of the beam 12. Therefore, one end of each auxiliary beam 13 is pressed down by the grooves 121. In addition, the pair of beam joint plates 3 are fixed to one end of the beam 12 and integrated, so that the beam 12 and the auxiliary beam 13 are joined in a state in which they are placed on the upper end of the column 11.

[0039] According to the beam support metal fitting 1B of the second embodiment and the wooden building construction method using the same as described above, in addition to the effects of the first embodiment, as shown in Fig. 5, it is possible to join a beam 12 that is hung from one direction to a column 11 that constitutes a wooden building 10, and an auxiliary beam 13 that is hung in a direction perpendicular to both sides of the beam 12. This makes it possible to construct a wooden building 10 in which a beam 12 is hung over a long span to a column 11 at the wall side, as shown in part B of Fig. 4.

[0040] Next, a third embodiment of the beam support hardware 1C according to the present invention and a wooden building 10 and a wooden construction method using the same will be described. Note that, among the components of the third embodiment, the same reference numerals will be used for the components that are the same as or correspond to the above-mentioned embodiments, and the repeated description will be omitted.

[0041] The beam support hardware 1C of the third embodiment is characterized in that, as shown in FIG. 7, a beam 12 and an auxiliary beam 13 facing each other are joined in a straight line to a pillar 11 that constitutes a wooden building 10.

In addition to the pair of beam joint plates 3 raised from the column-beam joint 21 and the beam load distribution part 22, the beam mounting plate 2 has a pair of auxiliary beam joint plates 32 raised from the auxiliary beam load distribution part 23 and joined to both side surfaces of one end of the auxiliary beam 13.

[0043] When constructing a wooden building 10 using the beam support hardware 1C of the third embodiment, first, the beam support hardware 1C is placed on the upper end of the column 11, and a pair of column joint plates 4 are joined to both sides of the upper end of the column 11 (column joint plate joining process). As a result, the pair of column joint plates 4 are fixed to the upper end of the column 11 and integrated, so that the beam 12 can be placed on the beam support plate 2.

[0044] Next, as shown in Fig. 7, one end of the auxiliary beam 13 facing the beam 12 is placed in a state where it protrudes beyond the auxiliary beam load distribution portion 23 toward the column-beam joint portion 21, and then one end of the beam 12 is placed on the beam placement plate 2. At this time, a recessed groove 121 into which one end of the auxiliary beam 13 is inserted is formed on one end surface of the beam 12, as shown in Fig. 7. Therefore, one end of the auxiliary beam 13 is pressed down by the recessed groove 121.

[0045] Thereafter, a pair of auxiliary beam joint plates 32 are joined to both side surfaces of one end of the auxiliary beam 13, and a pair of beam joint plates 3 are joined to both side surfaces of one end of the beam 12 (beam joint plate joining process). As a result, the pair of beam joint plates 3 are fixed to and integrated with one end of the beam 12, and the pair of auxiliary beam joint plates 32 are fixed to and integrated with one end of the auxiliary beam 13, so that the beam 12 and the auxiliary beam 13 facing each other are joined in a state of being placed in a straight line on the upper end of the column 11.

[0046] According to the beam support metal fitting 1C of the third embodiment and the wooden building construction method using the same, in addition to the effects of the first embodiment, as shown in FIG. 7, the beam 12 and the auxiliary beam 13 facing each other can be joined in a straight line to the column 11 that constitutes the wooden building 10. Also, as shown in FIG. 7, joints 14 such as dovetail joints can be provided on both sides of the joined beam 12, and the auxiliary beam 13 can be joined in an orthogonal direction. This makes it possible to build a wooden building 10 in which the beams 12 and the auxiliary beams 13 are hung from four directions over a long span on one column 11, as shown in part C of FIG. 9. Note that other beams 12 and auxiliary beams 13 that are not directly hung on the column 11 are omitted in FIG. 9.

[0047] Next, a fourth embodiment of the beam support hardware 1D according to the present invention and a wooden building 10 and a wooden construction method using the same will be described. Note that, among the components of the fourth embodiment, components that are the same as or correspond to those of the above-mentioned embodiments will be given the same reference numerals and will not be described again.

[0048] The characteristic of the beam support hardware 1D of the fourth embodiment is that, as shown in Figure 10, beams 12 of the same width facing each other are joined in a straight line to columns 11 that constitute a wooden building 10, and auxiliary beams 13 are joined perpendicular to the side faces of the beams 12.

Next, as shown in Fig. 10, one end of each beam 12 is placed on the upper surface of the beam mounting plate 2, and a pair of beam connection plates 3 are joined to both sides of one end of each beam 12 (beam connection plate joining process).

[0051] Thereafter, in the fourth embodiment, one end of the auxiliary beam 13 is joined to the side surface of the beam 12 in alignment with the auxiliary beam recess 31 (auxiliary beam joining process). At this time, in the fourth embodiment, a general joint metal (not shown) is attached to the position exposed by the auxiliary beam recess 31 on the side surface of the beam 12, and one end of the auxiliary beam 13 is joined by the joint metal.

[0052] According to the beam support metal fitting 1D of the fourth embodiment and the wooden building construction method using the same, in addition to the effects of the first embodiment, as shown in Fig. 10, beams 12 of the same width facing each other can be joined in a straight line to columns 11 that constitute a wooden building 10, and auxiliary beams 13 can be joined in a direction perpendicular to the side of the beams 12. This makes it possible to construct a wooden building 10 equipped with a beam 12 that is hung in a straight line over a long span to one column 11, and an auxiliary beam 13 that is hung in a direction perpendicular to the beam 12, as shown in part D of Fig. 9.

[0053] Next, a fifth embodiment of the beam support metal fitting 1E according to the present invention and a wooden building 10 and a wooden construction method using the same will be described. Note that, among the configurations of the fifth embodiment, the same reference numerals will be used for the configurations that are the same as or correspond to the above-mentioned embodiments, and the repeated description will be omitted.

[0054] The characteristic of the beam support hardware 1E of the fifth embodiment is that, as shown in Figure 12, beams 12 of the same width facing each other are joined in a straight line to columns 11 that constitute a wooden building 10, and auxiliary beams 13 are joined perpendicularly to both sides of the beams 12.

[0055] The beam support hardware 1E of the fifth embodiment has a basic structure similar to that of the beam support hardware 1A of the first embodiment described above, as shown in Fig. 13. Meanwhile, in the fifth embodiment, the beam joint plate 3 is provided with an auxiliary beam recess 31 for joining the auxiliary beam 13 in a direction perpendicular to the side surface of the beam 12 placed on the beam placement plate 2.

Furthermore, the beam support hardware 1E has a pair of auxiliary beam joint plates 32 that rise from the auxiliary beam load distribution portion 23 and are joined to both side surfaces of one end of the auxiliary beam 13.

Next, as shown in Fig. 12, each end of a pair of auxiliary beams 13 is placed on the auxiliary beam load distribution section 23 in a state where it protrudes from the auxiliary beam recess 31 to the column-beam joint section 21 side, and then one end of each beam 12 is placed on the upper surface of the beam mounting plate 2, and a pair of beam joint plates 3 are joined to both sides of the plate (beam joint plate joining process).

[0057] At this time, as shown in Fig. 12, grooves 121 into which the ends of the auxiliary beams 13 are inserted are formed on both side surfaces of one beam 12. Therefore, one end of each auxiliary beam 13 is pressed down by the grooves 121. In addition, a pair of auxiliary beam joining plates 32 are fixed to one end of the auxiliary beams 13 and integrated with each other, so that the beam 12 and the auxiliary beam 13 are joined in a state in which they are placed on the upper end of the column 11.
