US 5,061,111 A · Metal connector for wooden building and jointing structure of wooden building using the same

Abstract

A metal connector and a jointing structure with which two wooden members are jointed to each other with a sufficient fastening strength. The metal connector comprises a metal connector body and a pair of driven wedges. The metal connector body includes a bottom plate, a core plate secured vertically to the bottom plate, and a pair of wedge guide elements secured to the opposite side faces of the core plate. The metal connector body is connected to one of a pair of wooden members to be jointed to each other and is closely fitted in a fitting recess formed in the other wooden member such that empty portions are formed in the fitting recess adjacent the wedge guide elements. The driven wedges are driven into the empty portions of the fitting recess along the wedge guide elements of the metal connector body, whereupon the other wooden member is forced to move toward the one wooden member until an end thereof is closely contacted with an end of the one wooden member thereby to firmly joint the two wooden members to each other.

Dependent claims

A metal connector for jointing first and second wooden members to each other, comprising:

a metal connector body including a bottom plate, a core plate secured vertically to an upper face of said bottom plate, and a pair of wedge guide elements secured to symmetrical locations on the opposite side faces adjacent a longitudinal end of said core plate;
said first wooden member having a fitting recess formed at a jointing end thereof in a profile suitable to closely receive said bottom plate and core plate of said metal connector therein except that said fitting recess is enlarged, at portions thereof adjacent said second wooden member in which said wedge guide elements are received, to form empty portions when said metal connector body is received in said fitting recess;
said metal connector body being connected at the other longitudinal end thereof to said second wooden member;
and
a pair of driven wedges for being driven into said empty portions of said fitting recess along said wedge guide elements of said metal connector body to force said first wooden member toward said second wooden member until said jointing end is closely contacted with a jointing end of said second wooden member.
