However, in the above-mentioned column-beam joining member, since the column and the beam are joined by the support plate, there is a problem that the joining strength between the column and the beam is low.
Therefore, the present invention provides a column-beam joining member and a column-beam joining structure capable of increasing the joining strength between a column and a beam.

The beam-column joining member according to the present invention is a beam-column joining member for joining a column and a beam by combining a cylinder and a support, and the support is a first support plate. , The first support plate is provided with a second support plate insertion hole through which the second support plate is inserted, and the tubular body has a tubular space having a cross-sectional shape corresponding to the cross-sectional shape of the beam. A first support plate insertion hole through which the first support plate is inserted through one pair of side plates facing each other and a second side plate penetrating the other pair of side plates facing each other. It is provided with a second support plate insertion hole through which the support plate is inserted, and the plate surface of the first support plate is a surface along the central axis of the cylinder, and both ends of the first support plate are one pair of the cylinder. The first support plate is inserted into the first support plate insertion hole and installed in the cylinder so as to project outward from the side surface, and the plate surface of the second support plate is aligned with the surface along the central axis of the cylinder. The second support plate is formed in the second support plate insertion hole and the first support plate located inside the cylinder so that both ends of the second support plate project outward from the other pair of side surfaces of the cylinder. Since it is inserted into the second support plate insertion hole and installed in the cylinder, the column and the beam are joined via the support and the cylinder, so that the joint strength between the column and the beam can be increased. ..
Further, since a plurality of the first support plate and the second support plate are provided, the joint strength between the column and the beam can be further increased.
Further, in the beam-beam joining structure in which the pillar and the beam are joined by using the above-mentioned beam-beam joining member, the upper end side of the pillar installed below the beam-beam joining member is a pillar from the upper end surface of the pillar. A groove is formed in which the lower side of the first support plate and the lower side of the second support plate, which are extended in the extension direction of the beam and are located inside the cylinder, are inserted. A groove is formed in which the end side of the first support plate or the end side of the second support plate that extends in the extension direction and protrudes outward from the side surface of the cylinder is inserted, and the upper end side of the column opens the lower end opening of the cylinder. The lower side of the first support plate and the lower side of the second support plate, which are fitted into the inside of the cylinder and are located inside the cylinder, are inserted into the groove formed on the upper end side of the column, and are joined to the upper end side of the column by the beam beam. The member is joined, and the end side of the first support plate protruding outward from the side surface of the cylinder or the end side of the second support plate is inserted into the groove formed on the end side of the beam. Since the end of the beam and the first support plate of the beam-column joint member and the end of the beam and the second support plate of the beam-column joint member were joined, the column and the beam were joined. It is possible to obtain a beam-column joint structure that can increase the joint strength between the column and the beam.
Further, in the beam-beam joining structure in which the pillar and the beam are joined by using the above-mentioned beam-beam joining member, the lower pillar is on the upper end side of the lower pillar installed below the beam-beam joining member. A groove is formed which extends from the upper end surface in the extension direction of the column and into which the lower side of the first support plate and the lower side of the second support plate located in the cylinder are inserted, and is installed above the beam-column joint member. On the lower end side of the upper pillar, a groove is formed in which the upper side of the first support plate and the upper side of the second support plate, which are located in the cylinder body and extend from the lower end surface of the upper pillar in the extension direction of the pillar, are inserted. Then, the end side of the first support plate or the end side of the second support plate that extends from the end face of the beam in the extension direction of the beam and protrudes outward from the side surface of the cylinder is inserted into the end side of the beam. The lower end of the lower pillar is fitted into the cylinder through the lower end opening of the cylinder, and the lower side of the first support plate and the lower side of the second support plate located in the cylinder are the lower pillars. It is inserted into the groove formed on the upper end side to join the upper end side of the lower column and the beam-beam joining member, and the end side of the first support plate protruding outward from the side surface of the cylinder, or The end side of the second support plate is inserted into the groove formed on the end side of the beam, and the end of the beam and the first support plate of the beam-column joint member, and the end of the beam and the beam-column joint member The lower end side of the upper column is fitted into the inside of the cylinder of the beam-beam joining member joined to the upper end side of the lower pillar through the upper end opening of the cylinder to be fitted into the cylinder body. The upper side of the first support plate and the second support plate to be positioned is inserted into the groove formed on the lower end side of the lower column, and the lower end side of the upper column and the beam-beam joining member are joined. Since the upper and lower columns and the beam are joined, it is possible to obtain a column-beam joint structure capable of increasing the joining strength between the upper and lower columns and the beam.
In addition, since the joint strength between the lower column and the beam and the joint strength between the upper column and the beam are different, the joint strength between the upper column and the beam and the joint strength between the lower column and the beam are different. You will be able to have a relationship.
In addition, the groove depth of the groove formed on the upper end side of the lower column and the groove depth of the groove formed on the lower end side of the upper column are different, and between the upper end surface of the lower column and the lower surface of the beam. By configuring the vertical distance between the lower end surface of the upper column and the upper surface of the beam to be different, the joint strength between the lower column and the beam and the joint strength between the upper column and the beam Since the above is different, it becomes possible to have a magnitude relationship between the joint strength between the upper column and the beam and the joint strength between the lower column and the beam.
