As shown in this figure, in the conventional beam-to-column connection structure, a beam member having a T-shaped cross section is connected via a plurality of through bolts 2 (pull bolts) and nuts 2a that are horizontally inserted into a wooden column member 1. The base plate 3a of the metal fitting 3 is attached to the concave portion 1a on the side surface of the column 1, while the gusset plate 3b of the metal fitting 3 for connecting the beam member is inserted into the concave groove portion 4a on the end face of the wooden beam member 4, A detail in which the beam member 4 is connected to the beam member 4 by a joint such as a drift pin 5 is common. 11, the slab concrete 7 is provided on the upper surface of the beam member 4 via the lag screw bolt 6, and the wooden plug 8 is embedded in the end portion side of the drift pin 5, so that the column member. 1 shows an example in which a heat insulating material 9 such as a mortar bar is arranged at the edge of the concave portion 1a on the side surface of 1.

  In the case of such a joining type, when the beam member 4 is rotationally deformed with respect to the column member 1, the base plate 3 a of the metal object 3 having a T-shaped cross section is recessed into the column member 1 and at the same time, the extension of the through bolt 2. As a result, the rigidity of the joint portion is lowered, and there is a concern that the horizontal rigidity of the entire building including this column-beam joint structure may be greatly affected.

A joint member made of a material harder than wood, having an end surface, an upper column member disposed on the upper end surface of the joint member, and a lower column member disposed on the lower end surface of the joint member, The side of the beam member that protrudes up and down from the upper and lower end surfaces, is inserted and arranged in the upper column member and the lower column member, and is joined using a steel bar or bolt that is attached and fixed thereto, and faces the joint member of the beam member Since the metal bearing plate for transmitting the reaction force borne by this end to the joint member is provided on the side of the end of the wood, the wooden upper column member and the lower column member are harder than wood These are rigidly joined to each other by a steel bar or bolt through a joint member made of the above material. In addition, an input load that was borne only by a joint such as a drift pin or bolt installed on a wooden beam member in the conventional joint is borne by this joint and the bearing plate provided at the end of the beam member. By doing so, the possibility of destruction of the wooden beam member around the joint is reduced, and the toughness of the joint is improved. Therefore, the rigidity and proof stress of the joint can be improved as compared with the conventional joint type.

  Moreover, according to the other column beam connection structure according to the present invention, in the column beam connection structure formed by bonding the wooden column member and the wooden beam member, the protruding hardware for connecting to the beam member is provided on the side end surface. A joint member made of a material harder than wood, an upper column member disposed on the upper end surface of the joint member, and a lower column member disposed on the lower end surface of the joint member. A steel plate that protrudes up and down from the upper and lower end surfaces of the member and is inserted and arranged in the upper column member and the lower column member, and a through-hole provided in the steel plate and an insertion hole provided in the side surface of the upper column member and the lower column member The steel plate and the upper column member and the lower column member are joined to each other using a joint, and the side of the end of the beam member facing the joint member is borne by this end. Since the metal bearing plate is used to transmit the force to the joint member, the wooden upper pillar member and lower pillar Wood is rigidly joined to the second surface shearing by insertion placed steel plate via a Joint member made of a material harder than wood. In addition, an input load that was borne only by a joint such as a drift pin or bolt installed on a wooden beam member in the conventional joint is borne by this joint and the bearing plate provided at the end of the beam member. By doing so, the possibility of destruction of the wooden beam member around the joint is reduced, and the toughness of the joint is improved. Therefore, the rigidity and proof stress of the joint can be improved as compared with the conventional joint type.

  Moreover, according to the other column beam connection structure according to the present invention, in the column beam connection structure formed by bonding the wooden column member and the wooden beam member, the protruding hardware for connecting to the beam member is provided on the side end surface. A joint member made of a material harder than wood, an upper column member disposed on the upper end surface of the joint member, and a lower column member disposed on the lower end surface of the joint member. A steel plate that protrudes up and down from the upper and lower end surfaces of the member and is arranged so as to cover the side surfaces of the upper column member and the lower column member, and through holes provided in the steel plate and the side surfaces of the upper column member and the lower column member The steel plate and the upper column member and the lower column member are joined to each other through the provided insertion hole and joined to each other, and the end of the beam member on the side facing the joint member is connected to this end. Since the metal bearing plate is used to transmit the reaction force borne by the joint to the joint member, the wooden upper column Material and lower column member is rigidly joined to the second surface shearing by arranged steel sheet so as to cover through a Joint member made of a material harder than wood. In addition, an input load that was borne only by a joint such as a drift pin or bolt installed on a wooden beam member in the conventional joint is borne by this joint and the bearing plate provided at the end of the beam member. By doing so, the possibility of destruction of the wooden beam member around the joint is reduced, and the toughness of the joint is improved. Therefore, the rigidity and proof stress of the joint can be improved as compared with the conventional joint type.

  Further, according to the other column beam connection structure according to the present invention, the bearing plate is attached to the side surface of the end portion of the beam member with a wood screw or a coach bolt. Therefore, the portion provided with the bearing plate is reinforced, and the bearing plate is used. The effect can be increased.

  Moreover, according to the other column beam joint structure which concerns on this invention, since the joint member was comprised with the steel frame or the reinforced concrete, a column beam joint structure can be implement | achieved comparatively cheaply.

  As described above, the column beam connection structure according to the present invention is useful for a column beam connection structure in which a wooden column member and a wooden beam member are bonded, and in particular, to improve the rigidity and proof stress of the bonded portion. Is suitable.
