PROBLEM TO BE SOLVED: To provide a column-plate junction structure in a wooden framework used for a secure and safe building with sufficient earthquake resistance achieved by a main column which penetrates the building at a central section thereof from a foundation to a roof and plates which are inserted into through-holes provided on the main column.SOLUTION: A main column has a pair of upper and lower through-holes which horizontally penetrate the same in directions normal to two column surfaces and partially intersect one another at a right angle. Each plate has a horizontal upper surface along a longitudinal direction and an inclined lower surface along the longitudinal direction. A horizontal upper surface of a lower plate which penetrates the lower through-hole has a cut-out section at an intersection portion where the same intersects with an upper plate which penetrates the upper through-hole. The upper and lower plates are engaged with each other at the intersection portion with the upper plate inserted into the cut-out section on the lower plate and a gap section in the upper through-hole. In addition, the upper and lower plates are fixed to the main column with wedges knocked in gaps between an inclined surface of the upper plate and the cut-out section of the lower plate and between the lower plate and the lower through-hole in the directions opposite to insertion directions of the plates.SELECTED DRAWING: Figure 1 |
