A spacing and support construction member for wood frame construction which provides precise positioning and support for cross-members, such as joists and rafters, on their supporting members, and, in addition, provides for pre-nailing positioning of blocking pieces between cross-members, and furnishes supplementary vertical connection and support, the latter having special use in the attachment of rafters. The construction member comprises a center strip, laid longitudinally along support members, from which transversely-oriented perpendicular projections extend to position the cross-members for attachment. Additional projections provide supplementary horizontal, or, when bent about the edge of the supporting member, vertical attachment means for the construction member, permitting direct vertical connection between the cross-member and its supporting member. The projections from the center strip additionally provide edges for the positioning of blocking pieces between the cross-members for attachment. Placement notches on the center strip facilitate positioning the strip on the supporting member so that the blocking pieces will be aligned with a side surface of the supporting member. A starter and terminal strip, compatible with the spacing and support construction member, is provided to position and support the first and last cross-members of a run thereof.

A spacing and support construction member for use both in the attachment of multiple cross-members, such as joists and rafters, onto supporting members, such as top plates, and in the attachment of between-cross-member blocking pieces, the said spacing and support construction member comprising: a center strip; means for attachment of said center strip longitudinally along said supporting member, which means include perforations formed in said center strip for nailing; a plurality of pairs of projections, which projections of each said pair extend perpendicularly from the said center strip and parallel to each other, and are oriented transverse to the said center strip so as to form, along with the included portion of the elongated center strip, a channel-like framework into which a said cross-member may be positioned for attachment, the said projections of each said pair of projections being spaced one from another so as to correspond to the thickness of the said cross-member; means for attachment of said perpendicular projection to said cross-members which means include perforations formed in said perpendicular projections for nailing; the said pairs of projections being precisely located along the length of the said center strip at the position where said cross-members are be attached to said supporting member; nailing tabs formed and extending outward from the sides in the plane of of the said elongated center strip, the said nailing tabs providing additional mean for attachment of the said elongated strip to the said supporting member; the said nailing tabs being formed so as to be readily bendable at a right angle about a longitudinal edge of the said supporting member so as to permit the said additional means of attachment by the said nailing tab to be oriented at a right angle to the said means of attachment of the said center strip to the said supporting member; wherein, in the attachment of said cross-members to said supporting members and particularly in the attachment of rafters to a top plate, where the said center strip is laid horizontally along the said top plate, the said nailing tab can be bent over the said longitudinal edge of said supporting member and attached in such bent position so as to provide both horizontal and vertical attachment of the said spacing and support construction member to the said supporting member and vertical attachment of the said spacing and support construction member to the said cross-member, thus providing direct vertical-to-vertical attachment through the said spacing and support construction member between the said rafters and the said top plate, thereby supplying additional means for vertically holding the rafters onto the said supporting members; each said nailing tab having an outer edge at its extremity most distant from and parallel to the said center strip; and each said perpendicular projection having an outer edge at its extremity most distant from and normal to the said center strip; and the said outer edge of said nailing tab and the said outer edge of said perpendicular projection, located on the same side of the center strip and projecting an equal distance from the said center strip, combining to form a pair of blocking stops atop the said supporting member on which the said center strip is attached and between consecutive said cross members, against which said blocking stops a said blocking piece may be quickly and firmly positioned for subsequent attachment by nailing to the said cross-members and the said supporting member.
