Description

The present invention relates to a beam-column joint structure for fixing a beam to a column such as a carport.

Conventionally, a carport in which a support column and a beam are joined by a connecting member is known (see Patent Document 1). The connecting member is configured by joining a tubular half portion located in a column and another tubular half portion located in a beam by rivets.

Utility model registration No. 3113443

In the carport described in Patent Document 1, since the connecting member is formed by joining the tubular half portion on the support column side and the other tubular half portion on the beam side by rivets, the connecting member is attached to the upper end of the support column. In order to insert from, it is necessary to once lift the connecting member to a position higher than the upper end of the column, and the longer the tubular half part to be inserted into the column is formed, the higher the connecting member needs to be lifted. Becomes difficult.

It is provided with a reinforcing material extending in a direction, and the reinforcing material has a reinforcing front piece portion, a reinforcing rear piece portion, a first reinforcing side piece portion, and a second reinforcing side piece portion, and the reinforcing material is before the reinforcement. A hollow portion is formed by one portion, the reinforced rear piece portion, the first reinforced side piece portion, and the second reinforced side piece portion, and a joint body to which the beam is joined is fixed to the column. The hollow portion of the reinforcing material is connected to the first backing piece portion along the first reinforcing side piece portion and the first backing piece portion and along the second reinforcing side piece portion. A back support body having the second back support piece portion is arranged, and the joint body sandwiches the strut body and the first reinforcement side piece portion between the first back support piece portion and the support body. It is fixed to the first backing piece portion, and the second backing piece portion is fixed to the second reinforcing side piece portion.
