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.
