Title:
RIGID STRUCTURE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/137182
Kind Code:
A1
Abstract:
The present invention relates to a rigid structure, comprising: a plate-shaped body including a first bending part which has a thin plate and is bent with respect to a base part, and a second bending part bent with respect to the base part so as to form a gap from the first bending part; a fixing member including a first groove which is inserted and fixed in the gap and corresponds to the first bending part, and a second groove corresponding to the second bending part, thereby enhancing formability, simultaneously improving a lightweight characteristic and rigidity, reinforcing the strength by maximizing the rigidity using a bridge of a fixing member or a female-male coupling structure and the like, reducing deformation of a product, and greatly improving the formability and productivity.
