The beam clamp assembly (100) of the present invention allows use of beams (108) with end surfaces cut at right angles to the longitudinal length of the beam (108). A beam clamp assembly (100) has a base piece (100), a cap piece (12), abutments for beam ends, and means for clamping the base and cap pieces together with the ends of beams (108) held between them. Beams (108) generally slope downwardly away from the assembly. To allow beam ends cut square to lie flush with the abutments, these are correspondingly angled. They may be provided by facets of a polygonal wall (22) or L-shaped abutment pieces (14) than can be exchanged to allow for different slopes. ## Claims ### Claim 1 A clamped beam assembly comprising clamp means and a plurality of beans radiating from it in a non-coplanar array each of said beams terminating with an inner end abutment face which is perpendicular to its length, said clamp means comprising: a. a base piece including a floor defining a base plane and having a plurality of floor portions at angles to the base plane, each of said floor portions supporting an inner end of one of said beams; b. wall means rising from said floor portions and being arranged in an at least a partly-polygonal array in order to provide a plurality of abutment surfaces for receiving the inner end abutment faces of said beams, said abutment surfaces being perpendicular to their respective floor portions; c. a cap piece, having a plurality of crenellations along its lower edge; and d. means for clamping the base piece and the cap piece together with said inner end of the beams clamped between them and each of said inner end of the beams being received by one of the crenellations in the cap piece. ### Claim 2 (depends on 1) A beam clamp assembly according to claim 1 wherein the abutment surfaces are angled so that perpendiculars thereto are not coplanar. ### Claim 3 (depends on 1, 2) A beam clamp assembly according to claim 1 or 2 wherein the base piece comprises a floor and one or more walls which extend from the floor. ### Claim 4 (depends on 3) A beam clamp assembly accordingly to claim 3 wherein said walls provide said abutment surfaces. ### Claim 5 (depends on 4) A beam clamp assembly according to claim 4 wherein the floor defines a base plane and the walls are non-perpendicular thereto. ### Claim 6 (depends on 5) A beam clamp assembly according to claim 5 wherein the floor has portions at angles to said base plane which are perpendicular to respective walls so that a beam with an end face at right angles to a major face can abut a wall with its end face and a floor portion with said major face. ### Claim 7 (depends on 3) A beam clamp assembly according to any of claim 3 wherein the walls are arranged around a central hub. ### Claim 8 (depends on 3) A beam clamp assembly according to claim 3 wherein the plurality of abutment surface portions are provided by a plurality of angled abutment pieces locatable on or adjacent the base piece. ### Claim 9 (depends on 8) A beam clamp assembly according to claim 8 wherein the abutment pieces locate against the walls. ### Claim 10 (depends on 8) A beam clamp assembly according to claim 8 wherein the anqled abutment piece is provided with means for securing it to the base piece. ### Claim 11 (depends on 8) A beam, clamp assembly according to claim 8 wherein each angled abutment piece is L-shaped having two arms, with inner surfaces mutually at right angles and at least one of the arms having an outer surface at an angle to its corresponding inner surface. ### Claim 12 (depends on 11) A beam clamp assembly according to claim 11 wherein the inner faces of the arms of each angled abutment piece are grooved and the grooves provide a recess for engaging an end of a clamped beam. ### Claim 13 (depends on 7) A beam clamp assembly according to claim 7 wherein the plurality of abutment surface portions have beam attachment means. ### Claim 14 A clamped beam assembly comprising clamp means and a plurality of beams radiating from it in a non-coplanar array, each beam terminating with an inner end abutment surface perpendicular to its length; said clamp means comprising a base piece, a crenellated cap piece and means for clamping them together with inner end portions of the beams extending through the crenellations and being clamped between said crenellated cap piece and said base piece by said clamp means; the base piece comprising a floor and wall means rising from an inner region of the floor, said wall means providing an array of planar wall portions arranged so that the inner end abutment surface of each beam abuts a respective planar wall portion.
