Even if it does in this way, it is possible to aim at the improvement of joining efficiency similarly to said each embodiment.

  Further, in each of the above-described embodiments, a known technique such as a gusset plate, a lag screw bolt, a stud gibber, or GIR is applied to the joint portion. Therefore, according to the present invention, it is possible to provide a column beam connection structure with excellent workability and low cost. In addition, since the joints are clear, it is easy to accommodate fireproof specifications such as fireproof coating.

  In addition, the present invention can be said to be a general-purpose structure that can cope with the hybrid of a wooden pillar and various types of wooden beams. By making the beams wooden at the same time as the pillars, it is possible to provide a wooden space with excellent design.

  As described above, according to the present invention, it is possible to provide an excellent column beam connection structure having advantages such as space freedom, frame freedom, design, construction, cost, and fire resistance.

  As described above, according to the column beam connection structure according to the present invention, in the column beam connection structure formed by bonding the wooden column member and the beam member, the protruding hardware for connecting the beam member is provided on the side end surface. A lower column member, a horizontal plate-like floor member disposed on the upper end surface of the lower column member and the beam member, and an upper column member disposed above the lower column member across the floor member The upper column member, the floor member, and the lower column member are protruded vertically from the upper and lower end surfaces of the floor member, inserted and arranged in the upper column member and the lower column member, and bonded using a steel bar attached and fixed thereto. In addition, the reinforcement member capable of transmitting the bending moment of the end of the beam member to the floor member is arranged inside the floor member to improve the bending strength, so that the wooden upper column member and the lower column member are It is rigidly joined to each other by a steel rod through the member, and the reinforcing part inside the floor member Bonding efficiency is enhanced. For this reason, compared with the conventional joining format, the rigidity and proof stress of a joined part can be improved.

  In addition, according to another beam-column joining structure according to the present invention, the beam member is composed of a laminated material having built-in steel frames or wood, so that the beam-column joining structure can be realized at a relatively low cost. It is possible to provide a woody space excellent in design.

  In addition, according to another column beam connection structure according to the present invention, in a column beam connection structure formed by bonding a wooden column member and a beam member, a joint member made of reinforced concrete or concrete to which the beam member is connected; A lower column member disposed on the lower end surface of the joint member, a horizontal plate-like floor member disposed on the upper end surface of the joint member and the beam member, and disposed above the joint member across the floor member. The upper column member, the floor member, the joint member, and the lower column member protrude vertically from the upper and lower end surfaces of the floor member, and are inserted into the upper column member, the joint member, and the lower column member. Bending strength was improved by placing a reinforcing member capable of transmitting the bending moment of the end of the beam member to the floor member inside the floor member. So, wooden upper column member and lower column member are floor members and joints Together are rigidly joined together by a steel rod through the timber, bonding efficiency is enhanced by the reinforcing member inside the floor member. For this reason, compared with the conventional joining format, the rigidity and proof stress of a joined part can be improved.

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

  Moreover, according to the other column beam joint structure according to the present invention, the floor member is made of reinforced concrete and the reinforcing member is made of a reinforcing bar extending in the axial direction of the beam member. The joint efficiency can be increased by the reinforcing bars, and a column beam joint structure having excellent workability can be realized at a relatively low cost.

  Further, according to the other column beam connection structure according to the present invention, the floor member is made of a dry material typified by cross-laminated timber or lightweight cellular concrete, and the reinforcing member is arranged in the axial direction of the beam member. Since the rod-shaped reinforcing rod extending to the wall member is used, the reinforcing efficiency inside the floor member can be increased, and a column-beam connecting structure having excellent workability can be realized at a relatively low cost.

  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 beam member are bonded, and is particularly suitable for improving the rigidity and proof stress of a bonded portion. Yes.
