G-5 Flashcards
- Group of anchor bolts positioned?
Details are included in the working drawings and approved by a professional engineer
Layout the holes so that their position matches the holes in the base plate of the structural steel. (as per the shop drawings)
Position the template so that the center marks coincide with the string lines
- Protect anchor bolt threads in a concrete placement
Wrapping the bolts with tape, or coating them with grease will protect the threads. Cover exposed threads with a pipe, end of pipe should be covered by mushroom cap.
- Find centre-to-centre location of anchor bolts
Use framing square and tape measure to check diagonals and centre-to-centre distances. Use string lines to locate points halfway between bolt positions
- Uniform contact between the machine base+slab
metal shims are used to level the machine during installation, and the gap must be filled with grout.
- Metal angle iron sometimes embedded outside edge
Angled metal plates are used to protect the edges of loading docks, doorsways, or on exposed corners of colums or walls in high traffic areas. Attach to form using nails,bolts, or wire.
- Secure precast walls to foundation
Weld plates are used to connect pre-cast walls
- BCBC = The distance reinforcing steel must lap
Multiply horizontal bar diameter by 24 vertically
- Smooth formed used in a joining of two slabs
Smooth dowels are used to keep two slabs in alignment. The dowels hold both slabs in place vertically while the smooth surface of the dowels allows the slabs to move horizontally.
- Imperial rebar diameter “10”
Approximate diameter of 10/8” (1 1/4)”
- Type of bolt with a loop called
Loop inserts, designed to use a coil bolt. used to support heavy loads.
- Job constructed reglets made in two pieces
create a groove ready reglet to receive counter flashing or direct embedding of the counter flashing into the concrete during placement
- Type of reglet that needs “no” caulking
PVC Reglet (duplex nails) and (“J” nails)
Window reglet
- The counter-flashing of a reglet
Counter-flashing can be placed into the groove left after stripping a two-piece reglet blockout. The flashing can also be cast directly into the concrete using a one-piece reglet blockout.
- What’s a reglet and location
A reglet is a continuous groove that is cut or formed into a wall, usually above the point of intersection with a flat roof.
- What’s a roof membrane
Type of roofing system for buildings (found off google)
- Man hole cover frame secured in place
Plastic Trough gets cast-in-place into the slab. A grate sits on a ledge that is part of the trough
- Installing form work for dock levelers
(two answers idk which is one)
A box that is set into the surface of a concrete slab, encased with concrete on five sides. Design the form so that it will come apart easily after the concrete is placed.
or
- Follow the manufacturer’s instructions for installing dock levelling units.
- Prior to placing concrete, check the following carefully
-control conduits are in place
-the elevation of the top of the formwork or unit
-the formwork of the unit is square
-the formwork of the unit itself for level.
- Water stop contains a hollow bulb
The hollow bulb in the center helps to reduce shearing forces if there is any movement in the concrete.
- Material used to shim inside of a concrete pour
Liquid Grout
- Split-serrated water stops
Serrated waterstops are used where differential settlement is expected and a firm grip in the concrete is required. Serrated waterstops come in widths from 4” to 12” and thickness of 1/8” to 1/2”
- Done to the thickness of a embedded metal door frame
plug the holes in metal door frames with rubber stops to prevent concrete from running through.
- Type of metal door jambs
Metal door jambs are either knocked down(KD) or welded and ready to install. Either type may be used in concrete or masonry walls either before or after the wall is constructed. Welded jambs have a spreader bar tacked near the bottom to hold the jamb square during installation.
- Concrete fastener for pressure treated lumber
Tapcon Anchor, made with coating that is corrosion resistant.
- BCBC = maximum spacing of anchor bolts
not more than 2.4m apart
