GET IT 100% ACCURATE!!
Advantages of Gypsum Drywall - (ANSWER)low install cost, quick & easy
installation, fire resistance, sound control capability, easy availability, versatility,
ease of finishing & decorating, ease of installation of doors/other openings
Gypsum Drywall Edges - (ANSWER)Tapered: Most common; tapered on face side
along the long dimension of the panel & square edges at the end; allows for
application of reinforcing tape & joint compound without causing bulges at joints
Square: used where appearance is NOT a factor, for basic layers of 2-layer
applications & for veneer plaster work
Levels of Gypsum Drywall - (ANSWER)1: plenums above ceilings & other areas not
normally open to view (tape embedded in joint compound w/ surface free of
excess compound
2. water resistant backing board (all joints & angles have tape embedded in joint
& one separate coat of compound
3. heavy or medium textured finishes/heavy-grade wallcovering ( 2 coats of
compound)
4. Light textured or wallcoverings & where economy is concerned (3 layers)
5. all paints, severe lighting conditions (4 layers)
Studs are spaced how far apart? - (ANSWER)residential: 16" O.C.
,2
commercial: 24" O.C.
Slip Joint - (ANSWER)prevent wall from being damaged if the structural floor
deflects
Plaster Construction - (ANSWER)1. Scratch Coat
2. Brown Coat (level surface)
3. Finish Coat (Leveling & desired texture)
*Add Trim
Masonry Block Dimensions - (ANSWER)8"x8"x16" (-3/8" for mortar joints)
Demountable Partitions - (ANSWER)Consists of a system of individual
components that can be quickly assembled, disassembled & reused with nearly
total salvageability
consists of floor runners, ceiling runners, stud sections with clips to hold panels, &
prefinished gyp. wallboard panels
uses aluminum for framing
,3
Definition: Hinges - (ANSWER)Consist of 2 leaves with an odd number of knuckles
on one leaf and an even number of knuckles on the other
knuckles are attached with a pin
knuckle + pin = barrel (finished with tip)
Types of Hinge Tips - (ANSWER)-flat button (most common; typical)
-hospital
-oval head (typical)
-steeple
-flush
Butt Hinge - (ANSWER)MOST COMMON; has both leaves fully mortised into the
frame and the edge of the door so the hinge is flush with the surface of the frame
and door
raised barrel hinge - (ANSWER)used when there is not room for the barrel to
extend past the door trim; OFFSET to allow one leaf to be mortised into the frame
(kind of has an L shape on each side)
swing clear hinges - (ANSWER)has a special shape that allows the door to swing
90 degrees or 95 degrees so the full opening of the doorway is available
, 4
definition: latches & locksets - (ANSWER)device to operate a door, hold in
position & lock it
latchset - (ANSWER)ONLY holds door in place; NO lock (i.e. restroom partitions)
lockset - (ANSWER)special mechanism that allows the door to be locked with a
KEY or THUMBTURN
mortise lockset - (ANSWER)installed in rectangular area cut out of door; more
SECURE than cylindrical and offers wider variety of locking options
cylindrical - (ANSWER)most common; simple to install in holes drilled into door,
relatively inexpensive, most common in residential (like doors in home bedroom)
pre-assembled - (ANSWER)rectangular box that fits within a notch cut in the edge
of the door; easier to install than mortise; door knob OR lever can be used
center hung pivot - (ANSWER)allow door to swing in either direction & is
completely concealed
pivots CANNOT be used with a door stop (instead use a flexible strip of wool pile
or synthetic stripping can be rabbeted into the edge of the door) on the same side
of the door with both jambs because it makes it difficult to seal the door against
sound or light transmission on the hinge and strike sides
