Description
The present invention relates to a joining structure , a structural member , and a joining method. A known joining structure for connecting wooden members involves inserting a steel plate, joined to one wooden member, into a groove in the other wooden member, thereby joining the steel plate to the other wooden member. In the joining structure disclosed in Patent Document 1, drift pins are driven into holes in both the steel plate and the other wooden member to join them. The joining of the steel plate and the other wooden member is performed on-site. Japanese Patent Publication No. 2020-2669 This is a longitudinal cross-sectional view of a wooden member joining structure according to an embodiment of the present invention.This is a cross-sectional view taken along line A-A in Figure 1.This is a cross-sectional view taken along line B-B in Figure 1.This is an exploded perspective view of the joint structure of wooden members. The following describes the joining structure and joining method for wooden members according to embodiments of the present invention, based on Figures 1 to 4. As shown in Figures 1 and 2, the wooden member joint structure 1 according to this embodiment is a joint structure between a wooden column 2 and a beam 3. In this embodiment, the column 2 and beam 3 correspond to the first and second wooden members of the present invention. As shown in Figures 1 to 3, a concrete floor member 11 is provided above the column 2 and beam 3 (see Figures 1 and 2). As shown in Figures 1, 2, and 4, the first steel plate 4 is installed on the column 2. The second steel plate 5 is installed on the beam 3. The column 2 and the beam 3 are joined by joining the first steel plate 4 and the second steel plate 5. The column 2 and beam 3 are joined so that the end face 31 of beam 3 in the longitudinal direction faces the side face 21 of column 2 horizontally. The horizontal direction in the longitudinal direction of beam 3 where the side face 21 of column 2 and the end face 31 of beam 3 face each other is denoted as the X direction, and the horizontal direction perpendicular to the X direction in the width direction of beam 3 is denoted as the Y direction. Within the X direction, the side of beam 3 where column 2 is positioned is denoted as one side of the X direction, and the side of beam 3 where column 2 is positioned is denoted as the other side of the X direction. The first steel plate 4 has a first steel plate embedding portion 41 embedded in the upper end portion 22 of the column 2, and a first steel plate projection portion 42 projecting from the upper end portion 22 of the column 2 to the other side in the X direction. The first steel plate 4 is flat and is arranged so that its surface is a vertical plane facing the Y direction. The first steel plate 4 has the first steel plate embedding portion 41 on one side in the X direction, and the first steel plate projection portion 42 on the other side in the X direction. The first steel plate embedding portion 41 and the first steel plate projection portion 42 are provided integrally. The surface of the first steel plate projection 42 is a long rectangle in the vertical direction. The surface of the first steel plate embedded portion 41 is L-shaped. The vertical dimension of the other side of the first steel plate embedded portion 41 in the X direction (the side continuous with the first steel plate projection 42) is the same as the vertical dimension of the first steel plate projection 42. One side of the first steel plate embedded portion 41 in the X direction (the side away from the first steel plate projection 42) extends downward more than the other side. Furthermore, the first steel plate 4 may have a shape other than that described above, as long as it has a configuration that includes a first steel plate embedded portion 41 and a first steel plate protruding portion 42. A first groove 23 is formed in the upper end portion 22 of the column 2, into which the first steel plate embedded portion 41 is fitted. The first groove 23 opens upwards and on one side in the X direction. The first groove 23 is located in the center of the upper end portion 22 of the column 2 in the Y direction. The first steel plate projection 42 protrudes from the opening on one side of the first groove 23 in the X direction to the other side in the X direction. The upper edge of the first steel plate 4 is positioned at approximately the same height as the upper end of the column 2. The column 2 and the first steel plate 4 are joined by multiple first drift pins 61. As shown in Figures 2 and 3, the embedded portion 41 of the first steel plate has multiple holes 411 into which the first drift pins 61 are inserted. The upper end portion 22 of the column 2 has multiple holes 24 formed at positions that overlap with each of the multiple holes 411 in the first steel plate embedded portion 41 in the Y direction. The holes 24 reach the first groove portion 23 and penetrate the upper end port
