KURODA EIICHI / SEKI MARIKO / HEBIISHI TAKAHIRO / CHATANI YUKIKO

To provide a junction structure and junction method for fire-resistant columns and fire-resistant beams in a wooden building.SOLUTION: There is provided a junction structure of the fire-resistant beam and the fire-resistant column of the wooden building having the rigid-framed structure of the beam priority. Each of the fire-resistant beam and the fire-resistant column includes a load support layer, and a fire stop layer disposed on both sides of the load support layer. In the joint between the fire-resistant beam and the fire-resistant column, the fire-resistant beam and the fire-resistant column are joined so that beam is prior. A plurality of fire-stop units are affixed around the fire-resistant beam and the fire-resistant column that are joined together. The boundary surface between the plurality of fire-stop units is not flush with the boundary surface between the fire-resistant beam and the fire-resistant column.SELECTED DRAWING: Figure 7
