N E T SLAB The thinner portion of the floor, usually of uniform depth, that is between the drop heads or beams. SLING A length of cable with a loop at each end, usually the cable line from the crane hook to ganged form. SLIP FORM A form which moves, usually continuously, during placing of the concrete. Movement may be either horizontal or vertical. Slip forming is like an extrusion process with the forms acting as moving dies to shape the concrete. SNAP TIE A wire-type tie with or without spreader washer or cones. After forms are released, the protruding tie ends are snapped off by twisting at a predetermined break-off crimp usually about 1" in the concrete. SOLDIERS Vertical wales used for strengthening or alignment. SPANDREL BEAM A beam in the perimeter of a building, spanning between columns and usually supporting floors or roof. An up-turned spandrel depth dimension extends above the floor, and a down-turned spandrel extends below the floor. SPREADER A brace, usually of wood, inserted in forms to keep the form faces the proper distance apart until the concrete is placed. SPREADER BEAM A beam utilized to distribute the weight of a ganged form through two or more equalized vertical pick-up points. SPUD Adjustable bolt-like strut extending between the skin of tunnel forms and bored rock tunnel walls to provide position support of the formwork. STAKE A pointed wood or metal object driven in ground to attach brace or to support form sides in footing forming. STIFFENER A structural member for the support of the plywood face or skin plate on panel forms sometimes called ribs. STRIP To remove formwork from concrete. STRIPPING BAR A solid bar positioned in-between form panels or adjoining ganged forms which is the first unit stripped thereby providing relief to readily strip the large form panels; also referred to as “wrecking strips.” STRONGBACK A load gathering member attached to the back of the formwork on the outside of the walers for added strength, to hold proper alignment (sometimes referred to as “stiffbacks”). STUD Supporting member to which sheathing is attached. TAG LINE Line connected to gang form or flying form to control free swing movement during crane lifting. TAPER TIE A one-piece reusable form tie with a slight taper to facilitate removal. TELLTALE Any device designed to indicate movement of formwork. TEMPLATE Thin plate or board frame used as a guide in positioning or spacing of form parts, reinforcements, anchors, etc. TIE A concrete form tie is a tensile unit adapted to holding concrete forms secure against the lateral pressure of unhardened concrete, with or without provision for spacing the forms a definite distance apart, and with or without provision for removal of metal to a specified distance back from the finished concrete surface. TIE DADO Half-slot thickness dado’s at the siderails of adjoining forms provide the tie location slot common to many prefabricated form systems. TOENAIL To drive a nail at an angle. TRAVELER Traveling support and bracing for ganged tunnel and culvert formwork. WALER Load gathering members used to hold studs or panel forms in position. WALKWAY SYSTEM All components including, but not limited to, scaffold brackets, scaffold planks, guard rails, toeboards and guard rail posts erected to provide a work platform for placing and vibrating concrete and to prevent workers from falling. WATERSTOP Rubber, plastic, or other material inserted in a construction joint to prevent the seepage of water through the joint. WEDGE A piece of wood or metal tapered to a thin edge, used to adjust elevation, tighten formwork, etc. WEDGE BOLT A two-way action designed wedge which contains a slot to facilitate its function as a connecting bolt also.
