In this example, a long hole is formed in the connecting portion 71 of the third embodiment. 73 is drilled, and the long hole is provided in substantially the entire length of the connecting portion 71, the weight is reduced by the length of the long hole 73, and the toughness at the joint portion is improved.

  As described above, in this embodiment, the same operations and effects as the above-described embodiments can be obtained, and also in this example, it is possible to improve the toughness while improving the rigidity of the column beam bracket body 1 by the connecting portion 71. it can.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to said each embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the embodiment, the width, the length, the thickness, the number and arrangement of the coupling holes of the outer piece and the inner piece are the same, but they may be set differently. Further, in the embodiment, the connection between the column and the beam has been described. However, the connection between the column that is the first bonding member and the climbing beam that is the second bonding member, and the climbing beam that is the first bonding member and the second bonding member. It can also be used for joining at the top with a certain climbing beam. In these cases, the angle of the end faces of the first joining member and the second joining member is not about 45 degrees shown in the embodiment, but about 60 degrees or It may be approximately 120 degrees.
