A dual adjustment system performs both coarse and fine adjustments to tightly clamp a pair of jaws at the lower end of the stanchion upon the edge of a floor slab in an elevated, unfinished building structure. A coarse jaw adjustment sleeve formed of a short section of hollow steel tubing is coaxially disposed about an outboard support member in sliding engagement therewith. The coarse adjustment sleeve has one or more perforations therethrough so that a locking pin can be passed through it and through aligned openings in the outboard support member. A fine adjustment screw member is disposed coaxially within a vertical rail support tube and may be rotated by lever arms to move the upper jaw closer to or further from the lower jaw. Adjustment of the fine positioning mechanism is performed by manipulating handles at the top of the vertical rail support tube.

Load transfer plate for in situ concrete slabs
A tapered load plate transfers loads across a joint between adjacent concrete floor slabs. The top and bottom surfaces may taper from approximately 4 inches wide to a narrow substantially pointed end over a length of approximately 12 inches. The tapered load plate accommodates differential shrinkage of cast-in-place concrete slabs. When adjacent slabs move away from each other, the narrow end of the tapered load plate moves out of the void that it created in the slab thus allowing the slabs to move relative to one another in a direction parallel to the joint. Tapered load plates may be assembled into a load-plate basket with the direction of the taper alternating from one tapered load plate to the next to account for off-center saw cuts. A tapered load plate and an end cap may be used to provide load transfer across an expansion joint.

A construction and a method for fireproof sealing between the outer edges of a floor and the exterior wall structure of a building which includes the placement of an insulation support member between the safing insulation positioned immediately around the floor edge, and the spandrel insulation extending between the vertical studs inside of the outer cladding. Safing insulation is normally compressed prior to placement, and this compression is maintained by positioning the insulation support member in abutment therewith. Also, by positioning the insulation support member between the safing insulation and the spandrel insulation, the support member itself is protected which enhances maintenance of the effective seal of the slot between the floor and the outer cladding. Also during installation, the insulation support member can be used to achieve a desired compression of the safing insulation by positioning it after initial positioning of the insulation member such that it is compressed during final installation of the insulation member.
