Leçon 1
Foundations, Grouting & Anchor Bolts
Foundation Types
Equipment foundations must support the weight and dynamic forces of the machinery:
| Foundation Type | Application | Key Feature |
|---|---|---|
| Concrete block | Most common for rotating equipment | Mass dampens vibration |
| Steel frame | Elevated equipment, platforms | Lighter, allows access underneath |
| Spring-isolated | Sensitive equipment, vibrating machines | Reduces transmitted vibration |
| Inertia block | Reciprocating equipment | Extra mass absorbs impulse forces |
Grouting
Grout fills the gap between the equipment baseplate and the concrete foundation:
- Cementitious grout - traditional, non-shrink, cost-effective
- Epoxy grout - higher strength, chemical resistant, more expensive
- Pourable grout - self-leveling for uniform contact
Level Equipment
Use leveling screws or shims to set final position
→
Build Forms
Install grout forms around the baseplate perimeter
→
Pour Grout
Pour continuously from one side to avoid air pockets
→
Cure
Allow full cure before tightening anchor bolts
Anchor Bolts
- L-bolts - cast into the concrete foundation
- J-bolts - cast into concrete, hook shape
- Sleeve anchors - drilled into existing concrete
- Epoxy anchors - bonded into drilled holes with epoxy adhesive
Grout Air Pockets
Always pour grout from one side only and let it flow under the baseplate. Pouring from multiple sides traps air pockets that create unsupported areas, leading to vibration and cracking.
Key Takeaway
Concrete block foundations are most common for rotating equipment. Use non-shrink grout to fill the gap between baseplate and foundation. Pour from one side only to prevent air pockets. Allow full cure before tightening anchor bolts.
