N E T GENERAL & TECH INFO GLOSSARY OF TERMINOLOGY GLOSSARY OF TERMINOLOGY ALIGNER Lumber or metal members used to align vertical formwork. (plumbing strut oralignment device) ANCHOR BRACKET A projecting member designed in combination with a specified anchor to attach to a previous concrete pour so as to support the dead weight of the subsequent formwork and live loads specified. ANCHORS Devices used to secure formwork, braces or accessories to previously placed concrete, either embedded during placement or set in holes drilled in hardened concrete. There are two basic parts: the embedded anchor device and the external fastener which is removed after use. BATTER WALL Wall with one or both faces slanting from the vertical, usually creating a wall thicker at its base than at its top. BEAM FORM The entire formwork to form the bottom and both sides of a beam. BEAM POCKET Opening left in a vertical member in which a beam is to rest; also an opening in a column or girder form where forms for intersecting beams will be framed. BEAM SIDE Vertical side panels or parts of a beam form. BOX-OUT An opening or pocket formed in concrete positioning a box-like form within the wall forms. BRACE Any external structural member used to resist horizontal forces exerted on the forms such as wind loads. BRACKET Projecting member from a structure to support weight beyond its face. BREAK-BACK The distance from the face of concrete to the end of the remaining imbedded portion of a tie (snapped off wire-tie, or the face of concrete clearance of a three-piece tie inner unit) (also referred to as Cut-Back). BRICK LEDGE Ledge on wall or footing to support a course of (BRICK SEAT) masonry. BUCK Framing to void an opening in a wall, such as a door buck, which forms the opening for a door. BUG HOLE Void on the surface of formed concrete caused by an adhering air or water bubble not displaced during consolidation. BULKHEAD A partition in the forms blocking fresh concrete from a section of the forms or closing the end of a form, such as at the construction joint. CAMBER An inward curvature of a wall or an upward curvature of an elevated slab or beam form to improve appearance or to compensate for anticipated load deflection. CANTILEVER FORM A special forming technique in which the lateral concrete pressure is resisted by a cantilevered vertical member. CAPITAL The tapered upper section of a column under the drop head. Conical shaped with round columns, pyramidal shaped with square columns. CAULK To use a putty-type material to seal form joints from grout leakage. CHAMFER A beveled external corner. It is usually formed in the concrete work by use of a chamfer strip placed in the form at the outside corner to provide a rounded or beveled corner. CHASE An elongated void or opening formed into a concrete surface. CLEANOUT An opening in the forms for removal of refuse, closed before the concrete is placed. CLEAT Small board used to connect two or more pieces of formwork lumber together. CLIMBING FORM A form which is raised vertically for succeeding lifts of concrete in a given structure, usually supported on anchor bolts or rods embedded in the top of the previous lift. The form is moved only after an entire lift is placed and (partially) hardened; this should not be confused with a slip form which moves during placement of the concrete. COIL BOLT The hex-head outer unit of a three-piece wall tie with external contoured threads to engage the helical threads of a coil tie inner unit. COIL TIE The non-reusable inner unit or center part of a three-piece wall form tie. Ties are made with two or more straight wire struts with helix coils welded at each end forming female threads. COLUMN CLAMP Any of the various types of stiffening or fastening units to hold a column form sides together CONSTRUCTION JOINT The surface where two adjacent placements of concrete meet, frequently with a keyway or reinforcement across the joint. CONTROL JOINT Formed, saw cut, or tooled groove in a concrete surface to regulate the location of shrinkage cracks. CORBEL The projection from the face of a concrete wall which is used to support a beam or elevated slab. CROSSMEMBER Intermediate stiffening member of a form panel connected at both ends of the perimeter frame. CRUSH PLATE An expendable strip of wood used as a pad to protect either the form or concrete surface from damage during prying action to strip forms. DADO Rectangular groove in the perimeter frame of a form which allows for the passage of ties without leaving a gap between forms. DEAD LOAD The load of forms, stringers, joists, reinforcing rods, and the actual concrete to be placed. DEADMAN A steel beam, block of concrete or other heavy item used to provide anchorage for a guy line or form brace.
