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.
