Installing park benches on a concrete base requires proper planning and the right hardware to ensure a secure, stable, and lasting installation. The primary need is a reliable anchoring system. You cannot simply place the bench; it must be mechanically fastened.
The most common and effective method is using concrete anchors or bolts. Here’s what you typically need:
1. Anchoring Hardware: Use expansion anchors (like wedge anchors or sleeve anchors), concrete screws, or chemical anchors. The choice depends on the bench's weight and design. Through-bolt systems with epoxy are often considered the strongest for heavy public benches.
2. Proper Tools: You will need a hammer drill with a masonry bit sized for your anchors, a wrench or socket set, a vacuum for cleaning debris, and safety gear.
3. Installation Process:
* Mark & Drill: Precisely mark the mounting hole locations from the bench's leg plates onto the concrete. Drill holes to the depth and diameter specified for your anchors.
* Clean Holes: Thoroughly remove all concrete dust from the holes using a vacuum or compressed air. This is critical for anchor grip.
* Set Anchors: Insert the anchors into the holes. For expansion anchors, tighten the nut to expand the sleeve against the concrete. For chemical anchors, inject epoxy resin first, then insert the threaded rod.
* Attach Bench: Position the bench over the anchors, place washers, and securely fasten the nuts. Do not overtighten.
Key considerations include checking for underground utilities before drilling, ensuring the concrete slab is in good condition (not spalled or cracked), and potentially using a mounting template for accuracy. A proper installation prevents tipping, theft, and wobbling, ensuring public safety and durability for years of use.
