Figure 6-7 Assembling a step ladder
Step 2 Place the step ladder in the middle 5–10 mm away from the outward opening
door of the pre-fab. module, and mark mounting holes on the concrete pad for
the step ladder.
Step 3 Drill mounting holes using a hammer drill.
● When you drill a hole using a hammer drill, keep the drill bit perpendicular to the ground
and hold the drill stock firmly 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 fix its position, use a chisel to punch
a pit before drilling.
Step 4 Rotate nuts onto expansion sleeves to prevent the expansion sleeves from
fluttering.
Step 5 Knock the expansion bolts vertically into mounting holes until the flat washers are
flush with the floor.
Step 6 Remove the nuts, spring washers, and flat washers.
