  • Patent number: 4641480
    Abstract: A connector plate and tail truss are combined so that the formation of a floor truss of the tail truss type results wherein an extension of the top chord of the vertically spaced parallel chords extends outwardly beyond the end members of the truss so as to support the same on a bearing wall. The connector plate is of a general T-shape having a plurality of teeth struck therefrom with each of the plurality of teeth having a twisted shape with the outer portion of each of the teeth lying at approximately 50 degrees to the inner portion thereof adjacent the plate from which the teeth are struck. The twisted configuration of the teeth is such that any tendency of the truss to move vertically relative to the extended end portions thereof is resisted by the several teeth which tend to move inwardly of the timber of the truss so that the combined truss and connector plate resists sagging of the truss that would otherwise occur.
