To provide a structure (wooden rigid-frame structure) for integrating a column, a beam and a wall together, which is equipped with the annexation property of large-scale and small-scale buildings and which is achieved by the simplification of a processing member, execution of construction work and the like.

The structure has a mechanism, in which a column-beam member is joined and fixed by an integrating connection fitting using a tie nut and applied to coalition construction, and in which strength is increased by forming a wooden rigid-frame structure by stacking small-diameter wood wall materials to be integrated with a column and a beam on a wall. In the column-beam member, an iron bar (column-beam base shaft iron bar) is inserted through a part obtained by casing of the inside of a wooden square bar with a steel pipe, and a gap is filled with an urethane foam and a mortar resin.
