Prepare.

  In order to rigidly connect the column and the horizontal member by arranging the column joint main body in the pair of notches, for example, a high-tension bolt is inserted into the column side bolt hole as a male screw member and embedded in the column in advance. The fixing member may be screwed together, and a high tension bolt as a male screw member may be inserted into the horizontal member-side bolt hole, and then screwed into the fixing member embedded in the horizontal member in advance.

  On the other hand, a gap adjusting spacer is inserted into a gap generated between the horizontal member and the horizontal member-side mounting plate, or a gap generated between the contact inner surface of the notch and the column-side mounting plate. At this time, the gap adjusting spacer is inserted into the gap as described above so that the male screw member enters the notch of the gap adjusting spacer.

  In this way, as in the first aspect, in addition to the basic action that the column is rigidly connected to the horizontal member and the column is prevented from being pulled out, the horizontal member and the horizontal member side mounting plate Alternatively, the gap formed between the contact inner surface of the notch and the column side mounting plate can be closed by inserting a spacer for adjusting the gap, and the column joining body is notched in the vertical direction with no play. Therefore, it is possible to prevent deformation on the compression side, that is, rotational deformation during an earthquake, and to secure a rigid connection between the column and the horizontal member.

  In the column connector of the present invention according to claim 3, the tension resistor, the column-side mounting plate provided at one end of the tensile resistor, and the tension resistor so as to be parallel to the column-side mounting plate. In addition to a column joint main body configured with a fabric foundation side mounting plate provided at the other end, an eccentric washer fitted into the fabric foundation side bolt hole is provided.

  In order to rigidly join the column and the fabric foundation by arranging the column joint main body in the pair of notches, for example, a high tension bolt is inserted into the column side bolt hole and then screwed into the fixing member embedded in the column in advance. In addition, the anchor bolt may be inserted into the cloth foundation side bolt hole and a high tension nut may be screwed into the anchor bolt.

  In this way, in addition to the basic effect that the column is rigidly connected to the fabric foundation and the column is prevented from being pulled out, even if there is a construction error in the anchor bolt embedded in the fabric foundation, the construction error Is absorbed by the eccentric washer, it is possible to secure a rigid joint between the column and the fabric foundation.

  In the column connector of the present invention according to claim 4, the tensile resistor, the column-side mounting plate provided at one end of the tensile resistor, and the tension resistor so as to be parallel to the column-side mounting plate. When equipped with a column joint body composed of a cloth foundation side mounting plate provided at the other end, and an eccentric washer fitted into the cloth foundation side bolt hole, and when the column joint body is disposed in the notch An anchor bolt inserted between the fabric foundation and the fabric foundation side mounting plate or between the contact inner surface of the notch and the column side mounting plate and inserted into the fabric foundation side bolt hole or a male inserted into the column side bolt hole.

  In order to rigidly join the column and the fabric foundation by arranging the column joint main body in the pair of notches, the column side bolt hole is inserted with a high tension bolt as a male screw member and embedded in the column in advance. In addition to being screwed into the fixing member, an anchor bolt as a male screw member may be inserted into the cloth base side bolt hole, and a high tension nut may be screwed into the anchor bolt.

  On the other hand, a gap adjusting spacer is inserted into a gap generated between the cloth foundation and the cloth base side mounting plate, or a gap generated between the contact inner surface of the notch and the column side mounting plate. At this time, the gap adjusting spacer is inserted into the gap as described above so that the male screw member enters the notch of the gap adjusting spacer.

  In this way, as in claim 3, in addition to the basic effect that the column is rigidly contacted with the fabric foundation and the column is prevented from being pulled out, the anchor bolt embedded in the fabric foundation has a construction error. Even so, such construction errors can be absorbed by the eccentric washer.

  In addition, it is possible to close the gap formed between the fabric foundation and the fabric foundation side mounting plate or between the notch contact inner surface and the column side mounting plate by inserting a gap adjusting spacer. The main body is installed in the cutout with no play in the vertical direction.

  Therefore, it is possible to prevent deformation on the compression side, that is, rotational deformation during an earthquake, and to secure a rigid connection between the column and the fabric foundation.

  The notch is designed so that when the column joint or column joint body is placed in the notch, the horizontal member side mounting plate of the column joint or column joint body is in contact with the top of the horizontal member and the column side The height dimension and width are set so that the mounting plate is brought into contact with the contact inner surface of the notch.

  Similarly, the height of the column bonding tool or the column bonding body so that the cloth base side mounting plate is in contact with the top end of the cloth base and the column side mounting plate is in contact with the contact inner surface of the notch. Set the dimensions and width.

  Such a notch is an arrangement space in which the column connector or the column bonding main body is arranged, and the shape thereof is not limited, but specifically, a rectangular notch is conceivable.

  The horizontal member means a horizontal frame member such as a waistline, a girder, and a beam.

  If the tension resistor can resist tensile force via the column side mounting plate provided at one end and the horizontal member side mounting plate or cloth foundation side mounting plate provided at the other end, its structure and shape Although it does not matter, it is conceivable to form this with a cylindrical body and provide a working opening in the cylindrical body.

  When the tensile resistance body is formed of a cylindrical body in this way, when a bending moment is generated at the column base or the head of the column during an earthquake, a pair of column joints or column joint bodies are subjected to a tensile force on one side and compressed on the other side. In this case, since the tensile resistor is formed of a cylindrical body as described above, on the compression side, the compressive force acts on the entire tensile resistor. It is possible to prevent a local buckling from occurring due to an excessive compressive force flowing in a part of the column joint body. In other words, the column bonding tool or the column bonding main body also functions as a buckling prevention member.

  For work openings, for example, high tension bolts are inserted into the column side bolt holes and screwed together, and high tension bolts and anchor bolts are similarly inserted into the horizontal material side bolt holes and cloth foundation side bolt holes. This is used when screwing.

  Moreover, you may make it form a tension resistance body with a semi-cylindrical cylinder.

  In such a configuration, the above-described screwing operation can be easily performed.
