[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a joint structure of a composite beam in which a surface of a steel material is covered with a decorative material, and more particularly, to a joint portion between a column member or a beam member and a composite beam member, and both of them. The present invention relates to a joint structure between a wooden column or a beam and a composite beam, which simplifies the joining work of a composite material.

[0002]

2. Description of the Related Art Wood, steel, concrete and the like are generally used as structural building materials such as columns and beams. The joint structure of a pillar and a beam made of wood is mainly applied to a wooden building such as a wooden house, and both of them are joined by a pillar having a tenon and a beam having a tenon. The joint structure between a column and a beam made of a steel material is mainly applied to a steel frame structure, and these are joined by a bracket, a bolt and a nut, or welding.

[0003] Therefore, in the joint structure of the pillar and the beam of wood,
Since the beam is likely to be warped or bent, it is necessary to increase the sectional area of the beam. However, there is a problem that if the cross-sectional area of the beam is increased, the construction cost is increased and the economy becomes uneconomical. Therefore, recently, instead of wood, a joint structure between a column and a beam using a decorative material-coated square steel pipe configured by coating a surface of a steel pipe with a decorative material as a column and a beam has been proposed. (Japanese Utility Model Laid-Open No. 1-96901 (Japanese Utility Model Application No. 62-193807)).

[0004] The joint structure described in the above publication is a joint structure between a column and a beam made of a decorative material-coated rectangular steel pipe formed by coating the surface of a rectangular steel pipe with a decorative material,
The column and the beam are connected by a bracket and a connecting bolt, and this joint structure promotes simplification of an on-site joining operation.

[0005]

However, in the conventional joint structure described in the above-mentioned publication, both the column and the beam are both constituted by decorative material-coated square steel pipes (composite steel pipes). It has the advantage of being able to easily and firmly join columns and beams, but the structure of the joints of both the columns and beams is complex, and requires a great deal of labor to process the joints. There has been a problem that it is difficult to join them.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wooden column which can easily process a joint between a wooden column or beam and a composite beam, and can easily perform a joint operation on site. It is to provide a joint structure with a composite beam.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a joint structure for joining a pillar or beam made of wood, such as wood or glued laminated wood, to a composite beam made of a steel material coated with a decorative material. A mortise formed in a wooden pillar or beam, a composite beam having a tenon portion formed of a protruding steel material fitted into the mortise, the composite beam and the column or beam The above object is achieved by providing a joint structure for a composite beam, comprising: a bracket engaged with the composite beam, wherein the column member or the beam member is joined to the composite beam material by a connection bolt via the bracket. It was done.

[0008]

According to the present invention, when pillars and beams are factory-processed, mortises corresponding to the cross-sectional shape of the steel are provided on the columns, and bolt holes are provided near the joints of the composite beams. In order to join the column and the composite beam, the tenon of the composite beam is fitted into the mortise of the column, and these are connected by the bracket and the connection bolt. Just can be easily joined.
