The block member is connectable to the top or bottom of a vertical column or between two abutting vertical columns by a joiner insert composed of a flat flange section and a transverse stud section extending normally outwardly from one side of the flange to engage within a central hole provided in the end wall of the hollow block member. The joiner insert also includes a plug section extending normally outwardly from the flange section in a direction opposite the stud section to engage within a socket formed in the end portion of each column. The connector assembly also includes a T-shaped bracket engageable within a vertical slot formed in each end portion of the horizontal beams. The bracket includes a plurality of vertically spaced apart downwardly open hooks which slidably engage within, and securely lock with, the block member slots to thereby interconnect the horizontal beams with the end portion of a column or between the ends of two vertically abutting columns. ## Claims ### Claim 1 A connector assembly for connecting vertical wooden columns with the end portions of horizontal wooden beams, said connector assembly comprising, in combination: (A) a connector member composed of side walls and planar top and bottom end walls for closing off substantially the entire end portions of said side walls to form said connector member in a hollow block shape, said end walls each having portions defining a small, centrally located opening extending therethrough, said connector member: having a plurality of receiving apertures integrally formed with said connector member side walls and disposed along substantially the entire height of the side walls; (B) joiner insert means for interconnecting the ends of said connector member with the adjacent end portions of a corresponding wooden column, said joiner insert means including: a flat liquid impervious flange section for overlying substantially an entire connector member end wall; a first plug section extending normally from one side of said flange section to slidably engage within a corresponding connector member end wall central opening; and a second plug section extending normally from the side of said flange section opposite said first plug section to slidably engage within a socket formed in the end portion of the column; and (C) a bracket having: an elongate upright wall engageable within the end portion of a wooden beam, said upright wall having a forward edge adjacent the end of the wooden beam; a heel plate disposed transversely to, and fixedly attached to the bottom edge of said upright wall to underlie and support the bottom edge of the beam; and latch means extending outwardly from the forward edge of said upright wall to slidably, detachably engage with said connector member receiving apertures to securely lock said bracket with said connector member. ### Claim 2 (depends on 1) A connector assembly according to claim 1, wherein: the height of said bracket upright wall being substantially equal to the height of the connector member; and said latch means comprising a plurality of downwardly open hook members extending outwardly from the forward edge of said bracket upright wall and slidably engageable within said connector member apertures, said hook members being spaced apart along substantially the entire height of said upright wall forward edge at distances apart from each other corresponding to the spacing of said connector member apertures. ### Claim 3 (depends on 2) A connector assembly according to claim 2, wherein said connector member side walls are substantially planar; and the receiving apertures are disposed along a vertical row extending centrally along the height of each connector member planar side wall. ### Claim 4 (depends on 2) The connector assembly according to claim 2, wherein said bracket heel plate having a forward edge portion disposed substantially coplanar with the forward edge portion of said bracket upright wall, said heel plate forward edge portion extending transversely outwardly from both sides of said bracket upright wall forward edge portion for bearing against the adjacent connector member side wall. ### Claim 5 (depends on 1) A connector assembly according to claim 1, wherein said first plug section includes a circularly shaped stud fixedly attached to said flange member. ### Claim 6 (depends on 1) A connector assembly according to claim 1, wherein one of said plug sections is tubular in cross section. ### Claim 7 (depends on 6) A connector assembly according to claim 6, wherein said tubular plug section includes a plurality of flat side walls extending transversely to the plane of said flange section. ### Claim 8 (depends on 1) A connector assembly according to claim 1, wherein said first and second plug sections comprise a circularly shaped stud fixed relative to said flange member.
