Abstract Corner joiner units for connecting standard two-by-four lumber and the manner of making structures from these is depicted. The corner units are of plastic and have two horizontal sleeves for receiving horizontal two-by-fours and at least one vertical sleeve for receiving the butt end of a vertical two-by-four. The plastic unit includes internal walls and internal openings between the sleeves, so that each two-by-four received in the horizontal sleeves is in direct wood-to-wood contact with approximately half of the butt surface of the vertical two-by-four, so as to directly transfer vertical forces there between, without the joiner unit being subject to such vertical forces. Several variations of such joiner units are disclosed for different types of corners, as is a framework made from such members and two-by-fours.
In combination, a connector member comprising a unitary body, said body including a first sleeve defining a vertically oriented opening, a first piece of lumber fitted in said first sleeve opening, said body further including a second sleeve defining a first horizontally oriented opening disposed at substantially a right angle to said first sleeve opening, a second piece of lumber fitted in said second sleeve opening, said body further including a third sleeve defining a second horizontally oriented opening disposed at substantially right angles to said second sleeve opening, a third piece of lumber fitted in said third sleeve opening, said body further including a wall part extending into said second sleeve opening adjacent said first and third sleeve openings, said wall part constituting means for preventing ingress of said second piece of lumber into either of said first or third sleeve opening, said first piece of lumber constituting means for supporting said second and third pieces of lumber in wood to wood contact when said pieces of lumber are fitted in their respective openings.
