Abstract: Composite pan end connections for composite beam-joist construction are disclosed. Two versions of the composite pan can be fabricated on a standard break machine. A third version disclosed makes use of a standard steel stud. All three versions provide an economical, easily installed horizontal platform secured to the top chord seat angles of either conventional or composite open-web joists. In addition to economy in fabrication, and ease of use, the resulting rectangular shape of the concrete slab over the beam is structurally more efficient than heretofore obtainable.

Abstract: An improved deflection clip for connecting a stud to a structural building member while permitting relative compensating vertical movement of the clip, is disclosed. A planar sheet portion having a front end and a left and right side, has at least two perpendicular panels. A first panel extends downward at the front end of the planar sheet portion to form a bearing surface portion. The left side panel extends forward of the bearing surface portion and has an acute angle bend along its front width. This front segment is secured over the edge of a stud return, and the clip is then rotated so that the bearing surface portion contacts the outer surface of the stud flange. The laterally extending top surface of the planar sheet portion is then secured in any convenient manner to a bottom surface of a structural building member.

Abstract: A truss assembly for supporting a building brick or masonry wall comprising a top and bottom chord, a plurality of vertical and diagonal stud members interconnected between the chords; and a lintel angle, for supporting the brick wall, connected to the bottom of the stud members at least. Tieback members are provided which secure the wall to the truss assembly. Adjustment provisions allow aligning the truss assembly both vertically and horizontally before the wall is constructed. A further stud member spans the truss assembly horizontally and provides a physical connection between the truss and the concrete floor systems. Bracing is provided between the column supports, by interconnecting members between the floor slab and the bottom portion of the truss assembly.

Abstract: A precast concrete joist composite system having first and second spaced apart precast concrete joist members supported at their respective ends by a support, each of said joist members having a concrete portion, said joist members having at end portions respective projecting structures that have first parts anchored in said concrete portions of their respective joist members and second parts extending from said concrete portion end faces, said end faces having respective portions thereof that slope downward and away from said concrete portions, at least a first pan disposed at said end face, a first part of said pan element being disposed over the top surfaces of said concrete portions and a second part thereof disposed over said sloping portions of said end faces, and a decking element disposed over the respective said top surfaces of said first and second joist members and spanning the space between said joist members.

Abstract: An improved concrete slab and steel construction wherein a pan is extended between adjacent joists, said pan having a bend line axially along its length, a portion of said pan resting a joist, a second portion being transversely notched such that said pan straddles adjacent joists at said notches, said pan serving to support poured in place concrete such that said concrete haunches down to supporting beams, thereby forming a composite concrete slab and steel structure.

Abstract: An improved composite concrete and steel construction system for floor framing members using composite action open web steel joist and concrete slab construction, composite beams; unpunched corrugated decking and composite joists at columns only. All beams are composite and all joist ends are composite at the beams. Joists between the columns are standard open web joists. This composite system results in the columns having floor supporting members in both major directions that are composite with the poured in place concrete slab, thus providing superior bracing of the columns and direct duplication of the horizontal forces in the slab to the column through the supporting members. This design utilizes less composite joists, allows greater leeway in the spacing of the composite joist webbing and is economical. The floor slab will still act as a diaphram in both major directions due to the composite beams and the composite joists at the columns acting at right angles to one another.

Abstract: A composite action open-web steel joist, supporting beams and girders, and reinforced concrete slab interconnection. Upper apex portions of the steel joist webbing protrude through the upper chord members of the joist, and through apertures provided in the sheet metal formwork placed over such joists prior to the pouring of the concrete slab.
