Question 1

1. Group of anchor bolts positioned?

Answer 1

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

Question 2

2. Protect anchor bolt threads in a concrete placement

Answer 2

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.

Question 3

3. Find centre-to-centre location of anchor bolts

Answer 3

Use framing square and tape measure to check diagonals and centre-to-centre distances. Use string lines to locate points halfway between bolt positions

Question 4

4. Uniform contact between the machine base+slab

Answer 4

metal shims are used to level the machine during installation, and the gap must be filled with grout.

Question 5

5. Metal angle iron sometimes embedded outside edge

Question 6

6. Secure precast walls to foundation

Answer 6

Weld plates are used to connect pre-cast walls

Question 7

7. BCBC = The distance reinforcing steel must lap

Answer 7

Multiply horizontal bar diameter by 24 vertically

Question 8

8. Smooth formed used in a joining of two slabs

Answer 8

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.

Question 9

Answer 9

Approximate diameter of 10/8” (1 1/4)”

Question 10

10. Type of bolt with a loop called

Answer 10

Loop inserts, designed to use a coil bolt. used to support heavy loads.

Question 11

11. Job constructed reglets made in two pieces

Answer 11

create a groove ready reglet to receive counter flashing or direct embedding of the counter flashing into the concrete during placement

Question 12

12. Type of reglet that needs “no” caulking

Answer 12

PVC Reglet (duplex nails) and (“J” nails)

Window reglet

Question 13

13. The counter-flashing of a reglet

Answer 13

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.

Question 14

14. What’s a reglet and location

Answer 14

A reglet is a continuous groove that is cut or formed into a wall, usually above the point of intersection with a flat roof.

   -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.

Question 18

18. Water stop contains a hollow bulb

Answer 18

The hollow bulb in the center helps to reduce shearing forces if there is any movement in the concrete.

Question 19

19. Material used to shim inside of a concrete pour

Answer 19

Liquid Grout

Question 20

20. Split-serrated water stops

Answer 20
