To provide a column-beam joint structure which is small in deformation caused in a column and a beam made of wood material, and has good restoring performance even when a large force acts on a joint part between the column and the beam to cause deformation.SOLUTION: A column side steel plate 3 is fixed to a side surface of a column 1 made of a wood material, and a beam side steel plate 4 fixed to one end of a beam 2 made of a wood material is abutted on the column side steel plate in an overlapping manner to be joined by a plurality of bolts 5. One end of a bolt receiving member 51 having a predetermined length in the axial direction of the beam 2 is fixed to a surface of the beam side steel plate 4 which is abutted with the end face of the beam. A head of the bolt 5 engaged with the other end of the bolt receiving member, is disposed in the axial direction of the beam, penetrates the beam side steel plate 4, and has a tip end connected to the column side steel plate 3. The head of the bolt 5 and the bolt receiving member 51 are fixed so as to restrict the beam from being separated from each other in the axial direction. Further, a PC steel rod 6 penetrating from the beam to the column is arranged, and a tension force is introduced to introduce a compressive stress between the beam side steel plate and the column side steel plate.SELECTED DRAWING: Figure 2 【課題】木質材からなる柱及び梁に生じる変形が少なく、柱と梁との接合部に大きな力が作用して変形が生じても良好な復元性能を有する柱梁接合構造を提供する。【解決手段】木質材からなる柱１の側面に柱側鋼板３が固定され、木質材からなる梁２の一端に固定された梁側鋼板４を柱側鋼板に重ね合わせるように当接して複数のボルト５で結合される。梁側鋼板４の梁の端面と当接される面には、梁２の軸線方向に所定の長さを有するボルト受け部材５１の一端が固定されている。ボルト５は、頭部がボルト受け部材の他端に係止され、梁の軸線方向に配置されて梁側鋼板４を貫通し、先端部が柱側鋼板３と結合されている。このボルト５の頭部とボルト受け部材５１とは、梁の軸線方向への離脱を拘束するように固定されている。また、梁から柱に貫通するＰＣ鋼棒６が配置され、緊張力が導入されて梁側鋼板と柱側鋼板との間に圧縮応力度が導入されている。【選択図】図２
