Abstract

The present invention provides a jointing method, a jointing structure and an assembly part, which can reduce processing time and work capacity, and at the same time increase the processing accuracy of jointing part. The upper frames (1) which are taken as one pair of jointed components are formed with plate shaped projections. The longitudinal frames (2) which are taken as the other pair of jointed components are formed with inserting through holes. Through clamping the front end of the projection which traverses the inserting hole and cutting thereby dividing the projection to a plurality of projection parts (15), and at the same time deforming the adjacent projection parts (15A, 15B) to a reverse direction, the processing time and work capacity can be reduced without beforehand forminga plurality of projection pars or inserting through holes. Furthermore, through cutting the front end of projection and deforming the projection, the processing homogeneity can be realized for increasing the processing accuracy of jointing part and ensuring stable jointing strength.

Description

technical field

[0001] The present invention relates to a joining method, a joining structure, and an assembly. Specifically, it relates to a joining method and a joining structure for joining a pair of joined members, and an assembly for joining constituent parts to each other using the joining structure. Background technique

[0002] In the conventional structure for joining a pair of joined parts, for example, when assembling frame parts such as window frames and sliding door frames, the ends of a pair of frame parts (joined parts) that will cross each other are fixed with screws. joint structure.

[0003] As a structure for fixing with screws, a structure is used in which a screw hole is provided in one of the mutually joined frame members, and a screw penetrating from the outside of the other frame member is screwed into the screw hole. However, metal press-formed parts are often used as frame parts, and when screw holes are formed in such press-formed parts, screw hol...
