Install the supports

1.1.1.43

A. Install the expansion bolts

Before installation, use a vacuum cleaner to remove the dust inside and outside all the hole positions and then

measure the distance between the holes. Place the supports inside the holes to see whether the holes match

them. Do not mount the expansion bolt with large deviation to the holes. Instead, locate and drill the holes again.

Take out the gasket and nut of the expansion bolt, place the expansion rod and expansion bush vertically into

the hole and hammer the expansion bolt with a rubber hammer until it goes fully into the ground.

B. Adjust the supports

Roughly adjust the supports to their predefined height and fine tune the height-locking bolt of each support till the

upper support will not automatically slip. Place the supports at their installation positions and thread the

expansion bolts through the mounting holes on the supports.

C. Fix the supports

Align the holes on the antistatic floor with the connection holes on the support, screw in the bolts M12 × 70 from

the top down, and place the pressure plate assemblies in the method shown in Figure 4-16. Slightly knock the

supports with a rubber hammer and fine tune their height. Make the antistatic floorboard fall on the skeleton of

the floor according to its original position and ensure that the upper surface of the supports is closely pressed

against the antistatic floorboard. Then use a torque wrench to fasten the bolt of the pressure plate assembly, the

expansion bolt and the height-locking bolt of the support all to 45Nm. In this process, fasten the bolts in the

middle first before fastening the bolts at the two sides. Figure 4-17 shows the fastening of the bolts.
