Description

  The present invention relates to a joint structure between a column and a beam.

  In the conventional method, the column and the beam are joined by, for example, an uneven joint obtained by cutting a joint portion of wood, but in recent years, for example, a technique using a joint metal as described in Patent Document 1 has been performed. Proposed. According to such a technique, it is possible to improve the seismic strength by strengthening the joint between the column and the beam while omitting the labor and cost of cutting the wood joint.

Further, the end of the beam 20 and the end of the beam 20 joined to the end of the beam joint member 33 are prevented from spreading in the width direction, and the column and the first column joint member 32 and the second column joint member 34 are prevented. Can be firmly joined.

  The pillars 10A and 10B and the beam 20 are formed with insertion holes that open to the end surfaces thereof, and the insertion holes are filled with an adhesive, and then the first pillar connection bolt 41, the second pillar connection bolt 43, and Since the second beam connecting bolt 52 protrudes from the end face and is fixedly inserted, the connecting bolts 41, 43, 52 and the columns 10A, 10B and the beam 20 are firmly fixed, and the columns 10A, 10B, and The beam 20 and the joining members 32, 33, 34 can be firmly fixed by bolt and nut joining.

In the above embodiment, an example in which the bolt and nut are joined with one bolt is shown, but the present invention is not limited to this. On each surface, bolts and nuts may be joined with two or more bolts.
Further, in the above-described embodiment, the joint structure between the pillar and the beam at the corner portion is described, but the present invention is not limited to this. By adjusting the number of first beam connecting bolts 51 to be inserted into the column beam connecting member 31, the present invention can be applied to a column-to-beam junction structure such as a protruding corner portion or a wall portion without unevenness.
In addition, in a modification, the same code | symbol is attached | subjected to the same member as the said embodiment, and description is abbreviate | omitted.
