Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape member connection method for connecting end portions of two shape members each having a hollow portion, a shape member connection structure, and a crimping tool for connecting shape members.

A profile is a member formed into a predetermined cross-sectional shape by extrusion molding, and is used in various fields (fittings, curtain walls, etc.). For example, in a frame or frame of fittings, at a corner, a connecting member is arranged in a hollow portion of two shaped members to connect the ends of the two shaped members with the connecting member. Further, conventionally, a fitting frame is known in which two frames are crimped to join a corner piece to the two frames (see Patent Document 1).

In the conventional door frame described in Patent Literature 1, two frames are shape members having hollow portions and are connected by a corner piece as a connecting member. When the stiles are crimped, for example, the ends of the two stiles are butted against each other, and the two stiles are fixed to the crimping device with a clamp. In this state, the two stiles are pressurized and crimped by a crimping tool of the crimping device. However, there is a possibility that the two stiles are fixed to the crimping device and the ends of the two stiles are connected to each other while there is a step or a gap between the two stiles. If there is a step or a gap between the two stiles, it is necessary to adjust the connection position of the two stiles after caulking, and the work of connecting the two stiles is troublesome.
