Title:
METAL CONNECTION FITTING
Document Type and Number:
WIPO Patent Application WO/2011/086770
Kind Code:
A1
Abstract:
This metal connection fitting connects together a pair of members to be connected, and exhibits energy absorption performance according to relative displacement between said members to be connected. Furthermore, said metal connection fitting is a steel channel member equipped with a web and a pair of flanges, said web being intended to be connected to one of the members to be connected, said pair of flanges being provided at both ends of this web and intended to be connected to the other member to be connected, and said both ends being in an intersection direction that intersects with the direction of said relative displacement. Moreover, said web comprises damper sections and interposed sections, each of said damper sections comprising a plurality of damper pieces formed in a row in said intersection direction, said damper pieces undergoing plastic deformation in response to said relative displacement, resulting in the said each of damper sections exhibiting said energy absorption performance, and said interposed sections being provided between the damper sections and the flanges. Furthermore, said metal connection fitting comprises a pair of frame edge sections, and strutting sections, said pair of frame edge sections being allocated in such a way as to include said interposed sections and said flanges, and said strutting sections being allocated so as to provide struts between those ends of said pair of frame edge sections which are in the direction of said relative displacement.
