Figure 4-2 Hoisting a pre-fab. module
Step 2 Use four angle steel brackets to secure the pre-fab. module.
1. Remove the rubber plugs from the pre-fab. module
xing holes using a
Phillips screwdriver.
2. Align the two mounting holes in an angle steel bracket with the two holes on
the pre-fab. module, and mark the hole positions for mounting the angle
steel bracket on the concrete platforms using a marker.
– Mark all four mounting holes where each angle steel bracket contacts the
concrete platform.
– Place a wooden block on the top of an expansion bolt, and then knock at
the wooden block using a claw hammer to avoid damaging the expansion
bolt.
– When you drill a hole using a hammer drill, keep the drill bit perpendicular
to the ground and hold the drill stock
rmly with both hands to prevent
irregular drilling and damage to the ground.
– If the ground is too hard and smooth for the drill bit to secure its position,
use a chisel to punch a pit before drilling.
– Before you hammer an expansion bolt vertically into a mounting hole,
clean up dust from the inside and surrounding of the hole.
– Each angle steel bracket must be secured by two mounting holes.
Preferentially drill the outer two mounting holes. If steel bars in a concrete
platform block the drill bit, drill the inner mounting holes.
