Structural engineered wood rim board corner system and method for light frame construction

摘要

A structural engineered wood rim board corner system for light frame construction involves two intersecting structural engineered wood rim boards each having a cavity on an exterior angle side of the intersection and an auxiliary corner support having two arms, each within a respective one of the cavities, is disclosed. A corresponding light frame construction corner forming method is also disclosed.

主权项

1. A structural engineered wood rim board corner system for light frame construction comprising:
A) two structural engineered wood rim boards, wherein
i) each of the two structural engineered wood rim boards is made up of a pair of flanges connected by a web so as to form a recessed cavity in-between the flanges on one side and on an opposite side of the structural engineered wood rim boards the pair of flanges and web form a surface that is substantially flat,ii) the width of the web of each of the two structural engineered wood rim boards is at least 50% of the overall width of the structural engineered wood rim boards,iii) the two engineered wood rim boards are abutted relative to each other at corresponding ends so as to form an angled intersection, with the cavity being on an exterior angle portion of the intersection; and B) an auxiliary corner support made up of two arms oriented at an angle relative to each other corresponding to the angled intersection, wherein
i) the auxiliary corner support has a width less than the width of the web and between 6¼″ and 8⅞″,ii) one of the two arms of the auxiliary corner support is within one of the cavities and the other of the two arms is within the other cavity, andiii) each of the two arms abut and are affixed to their corresponding webs, so as to concurrently (1) maintain the two engineered wood rim boards at an orientation relative to each other corresponding to the angle, and (2) assist the web in transferring a load applied to the upper flanges near the corner to a part of the structure below the lower flanges while resisting spreading of the corresponding ends of the two engineered wood rim boards at the angled intersection.
