Description

The present invention relates to a door frame connection structure.

The conventional door frame is manufactured by manufacturing the upper and lower frame members and the left and right frame members, respectively, and welding the ends of each member. This assembly method has been used as a general method for many years. However, in order to weld separate members, one person needs to press the end of the member, and two people have to work. Furthermore, after the welding, a post-treatment is necessary to remove the welding marks.

Therefore, in view of improving the workability of assembling the door frame, assembly without using welding is desired. Patent Document 1 describes a door frame connection structure that does not use welding work. However, the door frame disclosed in Patent Document 1 connects the vertical frame member and the horizontal frame member using a piece formed by bending the periphery of the opening formed in one member, and is sufficiently strong. It couldn't be said to be a good one. Moreover, the connection by a rivet has the fault that it is weak to rotation of the members to be connected.
